Modular structure of CNC vertical lathe

With the development of machine tool related technology, the structure of CNC vertical lathe is also constantly developing, and its modular structure must reflect the increase of functions, expand the process performance, and improve the automation level of control. In order to reduce the special process equipment and installation adjustment time for processing new parts, multi-purpose tool holders, tool magazines and inspection devices for directly inspecting part sizes should be added (all of which represent the development trend of modular vertical lathe modularity). This paper will explain the realization process of the modular structure of CNC vertical lathe based on the structure of a series of CNC vertical lathes.

1 The horizontal series modularization of the workbench module workbench module is divided into general workbench, indexing workbench, mobile workbench and exchange workbench according to different purposes. The vertical series modularization is divided into 5 sections from 125Ctam to 3150mm according to the processing diameter. Therefore, each horizontal series has 5 vertical series modules.

In order to be able to easily machine the end face, the side surface of the workpiece and the hole different from the axis of rotation of the blank, a table indexing device can be added on the basis of the general workbench to obtain the indexing table structure module.

The indexing device includes a faceplate refilling device, a swivel reading sensor, and a faceplate positioning gripper. In order to make the tool move in three dimensions, a movable table is designed. In the manufacture of flexible processing units and flexible processing systems, in order to automatically exchange workpieces, the towing station, the storage table and the alignment table should be added to form an exchangeable table. The structural modules of the horizontal series of the workbench mainly increase the functions of the machine tools to meet the needs of the multi-purpose workbench.

The basic part of the 2 tool holder module is a welded part. The main factor to consider when performing the vertical series modularization of the tool holder is the effect of the maximum cutting force.

When the machining diameter is less than 1250mm, the specification is a module with a specification. When the machining diameter is 1250mm to 3150mm, the maximum cutting force varies. When the horizontal series of the tool holder is modularized, it can be divided into a tool holder and a milling cutter according to its function. Among them, the tooling and tool clamping of the tool holder are manually carried out, and the four- or six-square tool table indexing tool holder is used; if the tool is automatically clamped, the single-knife automatic clamping type tool holder is used. The single-knife automatic clamping type tool holder has two types: non-rotating type tool holder and rotary type tool holder. In order to expand the technical performance of the machine tool, if the milling function head is mounted on the vertical tool holder, only the tool rotary type vehicle can be used. Tool holder. The formation of the horizontal series of tool holders is mainly adapted to the degree of automation of the machine tool and the need to meet the functions of the machine tool.

3 The support module support module mainly has a column, a beam and a slide module, and the basic parts are large parts of the numerical control vertical lathe, which are cast. Therefore, the modularization of the support module mainly considers the modularization of large parts. The purpose of the modularization is to expand the working space of the machine tool, so that the specifications of the machine tool have the possibility of changing under the premise of ensuring the rigidity of the machine tool.

The horizontal series modularization of the column is mainly divided into three types: basic type, light type and heightened type according to the change of the processing height; the horizontal series modularization of the beam is mainly determined according to the range of movement of the tool holder in the horizontal direction. Since the tool magazine is mounted on the beam body, the installation of the tool magazine affects the movement of the tool holder in the horizontal direction. Therefore, the length of the beam should be changed depending on whether the tool magazine is installed or not and the installation position. For example, if the magazine is loaded on the right side of the beam, the right side should be lengthened accordingly. The role of the slide is mainly to support the tool holder, does not affect the processing range of the machine tool, and its use is relatively simple, so there is no need to develop a horizontal series.

The columns and beams have a large variation in stiffness within the range of their machining diameters, which are standardized as five vertical series modules. The beam body adopts a box-shaped structure, and the back structure of the vertical series module is sequentially increased. Due to its small change in stiffness, the vertical series of slides are divided into two types. The module is a module with a diameter of 1250mm or less. When the diameter is 1250mm to 3150mm, it is a module of another specification.

Not large, standardizing a module of one specification. The primary stage of the Xinjiang-Zhujia-PushingH block is mainly large-scale modularization. The modular design of the vertical lathe in Wuzhong Factory is basically at this level.

4 Transmission module transmission module mainly has main transmission, vertical and horizontal feed box, beam lifting box and other modules. Its transmission structure is relatively mature, and it is not suitable to develop horizontal series products with different structures. The vertical series modularization mainly considers the strength and stiffness problems caused by the power. Due to the difference of the transmission power, when the machining diameter is below 1250mm, the specification is a module of one specification. When the machining diameter is 1250mm to 3150mm, the specification is another specification. Module.

For the beam lifting box module, there are 4 kinds of maximum machining heights of the machine tool in the machining range of the machine tool, and the corresponding beam lifting stroke is also different, but only the screw can be replaced. Therefore, the beam lifting box module only needs one specification.

5 Auxiliary module and monitoring module Auxiliary module and monitoring module are independent functional units, which can be optional, easy to assemble and match. The main function is to expand the machine function, increase the degree of automation and improve the processing efficiency. For the milling head, the protective cover and the towing device, the components can be modularized; the workpiece measuring device, the in-machine tool setting device and the tool monitoring device can realize the modularization of the functional unit.

For automatic tool changers, horizontal series modules can be developed depending on the application and performance. If only the turning tool is required to realize automatic tool change, the disc type tool magazine is used; if both the turning tool and the milling cutter need to be automatically replaced, a double-layer disc tool magazine is used, and 4~6 non-rotating tools are stored in the upper layer ( Clipper), the lower layer (up to page 34) of the graphic file (.dwg). Load and run the above program, type *(load*profile.lsp*)* at the command line, enter the profile, and run continuously until you get all the tooth profiles of the gear, such as (c), (b) for the gear teeth. Form the picture in the process.

2 The method of generating the entire tooth profile of the involute gear by the conversion of the automatically generated solid gear generally has software for automatically generating the physical gear function, which can be used for this type of method. We use CAXA-V2, a solid modeling software developed by Beihang, as an example.

In its solid modeling environment, after clicking the gear icon in the tool item, in the dialog box that appears, specify the number of teeth, the tooth shape, the pressure angle and the radius of the index circle, etc., to generate the corresponding solid gear, and then save the disk.

In its drawing environment, the corresponding solid gears can be directly converted to the desired multi-face view.

Store the smaller diameter shank and milling cutter. The large-capacity milling cutters required for flexible machining units use a rotary drag chain magazine with a robot for automatic tool change.

Auxiliary modules and monitoring modules best reflect the development level of vertical lathes. With the development of modern technology, the modularization of auxiliary modules and monitoring modules should be taken seriously when designing the vertical lathe.

The modular design of the CNC vertical lathe is finally embodied in the modular structure. For each functional module, there are structural modules with different uses and different structures. The collection of these structural modules constitutes the module library of the CNC vertical lathe. From a functional point of view, the functions of mechanical products can be decomposed into functions such as transmission, execution, support, auxiliary and monitoring. The purpose of the design is to realize the transformation from function to structure. In accordance with this, the structure of the mechanical product can also be composed of modules such as transmission module and execution module. Different modular methods are adopted for different modules, so that the transmission module is generalized, the execution module is expanded, and the support module is adjustable. The self-control of the monitoring module can truly reflect the advantages of modular design.
