Description

A dual-station integrated fixture for manufacturing industrial robots

technical field

The invention relates to a fixture used in horizontal machining of mechanical parts, in particular to a fixture used for processing a fixed plate of an injection molding machine part on a horizontal machining center.

Background technique

At present, when processing the fixed plate of injection molding machine parts, a double-station horizontal machining center is selected. The fixed plate has six faces, which are processed by a horizontal machining center. As shown in Figure 3 and Figure 4, the fixed plate is three-dimensionally oriented, the horizontal direction is X direction, the vertical direction is Y direction, and the paper feeding direction is Z direction. The part of the fixed plate that involves fixture clamping and positioning reference during processing includes the foot Reference surface A14, assembly bottom surface A15, Z-direction positioning surface A16, positioning reference surface A17, X-direction rough reference A18, X-direction fine reference A19, assembly bottom surface B20, Z-direction reference surface B21, Z-direction reference surface A22, Y-direction reference Surface A23, X-direction coarse reference B24, Z-direction reference surface B25, Y-direction reference surface B26, positioning reference surface B27, Z-direction reference surface C28.

In the existing processing process, two processes are adopted, and two separate fixtures are required, which are respectively clamped on the workbenches of the two stations of the machining center, as shown in Fig. 5 and Fig. 6 . During the processing of the first process, the operator clamps the second process at another station. Since the processing time of the first process is relatively short, the time of the second process is long. This leads to insufficient clamping time for the second process, and the machine tool stops processing and waits for the clamping to be turned to the side of the spindle for processing. This reduces the utilization rate of machine tools and increases production costs. In addition, the fixture accessories are assembled by processing and welding steel parts. The fixture structure of steel welding and screw assembly will be deformed or the assembly position will be shifted, the structural strength is not high, and there will be internal stress after welding. In addition, when the fixed plate is processed in the second process, there are 4 sides of the product that need to be processed. The product is placed in the center of the workbench so that the processing tool is too long, resulting in slow processing speed and unstable dimension of vibration tool accuracy.

Contents of the invention

In order to overcome the shortcomings of low utilization rate of machine tool, long tool, slow processing speed and unstable size in the current processing, the present invention provides a fixture for double-station horizontal machining center to process and fix parts of injection molding machine Plate, this kind of fixture can not only improve the efficiency of the machine tool, but also ensure high-speed and large-scale machining, and the accuracy and quality of the product are guaranteed.

The technical scheme adopted by the present invention to solve the technical problem is: the processing machine tool remains unchanged, the processing technology of the fixed plate is adjusted, and after the adjustment, each process only processes the dimensions on three surfaces. In this way, the product can not be installed in the center of the workbench, and the product needs to be processed as close as possible to the main shaft within the travel range of the machine tool, so that the cutting tool can be shortened and the processing speed can be increased. Integrate the two processes of the product into two different stations of a fixture, so that there will be no problem that the processing time of the two processes is different, causing the machine to stop to clamp the product. After such adjustment, the two worktables of the machine tool can respectively make two kinds of products with similar processing time and clamping time, which improves the utilization rate of the machine tool.

This adjustment is realized by utilizing the double-station integrated fixture for manufacturing industrial robots of the present invention. Specifically, the scheme adopted by the present invention is:

A double-station integrated fixture for manufacturing industrial robots, which is used to clamp the fixed plate when processing the fixed plate of an injection molding machine horizontally, is characterized in that the fixture for manufacturing industrial robots is a double-station integrated fixture The main body 2 includes a bottom plate and two vertical plates integrated with the bottom plate. The two vertical plates are combined through a skeleton, and a pad 1, an X-direction adjusting screw 3, a Y-axis support A4, and a Y-axis are installed on one of the vertical plates. Axial support B5; Z-direction screw backer 6, hook platen 7, Z-direction support nail 8, X-direction pressing screw 9, Y-direction movable support A10, Z-direction pressing screw A11, Y-direction are installed on another vertical plate Press the screw B13 toward the movable support B12 and the Z direction. When adopting the dual-station integrated fixture for manufacturing industrial robots of the present invention, each vertical plate and the accessories installed on it represent a station, and each station processes three faces of the fixed plate, so each fixture clamps Holds two fixed plate parts, so the processing time of these two stations is basically the same or similar. After the processing is completed, the two processes are reversed to complete the processing of the corresponding other process, and the efficiency is greatly improved.

The bottom plate and the vertical plate of the fixture main body 2 can be integrated together in any way, but for the sake of stability and firmness, it is preferred to be an integrally formed integral body.

The beneficial effects of the present invention are:

The main body of the fixture is cast and formed, and its strength is better than that of steel parts welded or assembled. The non-standard parts used in the fixture and the size of the processing are reduced, and a large number of standard parts are used to improve the design and processing speed. Reduce the cost of jig manufacturing and reduce the number of jigs. After using this new type of fixture, the machine tool can process 2 kinds of products, and only one kind of product can be processed before. Reduce administrative costs for machine allocation in the production department. The processing tool is shortened, the processing speed is increased, and the production efficiency is increased.

Each vertical plate of the fixture main body 2 represents a station, and each station corresponds to a corresponding process. Specifically, a pad 1, an X-direction adjusting screw 3, a Y-axis support A4, and a Y-axis support B5 are installed on a station. Among them, the spacer 1 is assembled on the main body of the fixture with screws, which plays the role of positioning and fixing the Z direction; the X-direction adjusting screw 3 is in the threaded hole on the main body of the fixture 2, and the X-direction coarse reference B24 of the fixed plate is leaned against to play the role of X-direction. Clamping action in the top pressure direction; Y-axis support A4 cooperates with the X-direction fine reference 19 to position the fixed plate; Y-axis support B5 cooperates with the X-direction fine reference 19 to position the fixed plate. Thereby a process is fixed at this station.

Among them, the Z-direction screw backer 6 leans against the Z-direction datum C28 surface to position the Z-direction of the fixed plate; the hook-type pressure plate 7 is assembled on the fixture main body 2 to clamp the product; the Z-direction support nail 8 leans against the Z-direction datum plane On A22, rough positioning fixes the Z direction; X-direction pressing screw 9 presses on the X-direction rough datum A18 to position the X-direction; Y-direction movable support A10 is assembled on the main body of the fixture, and the floating support is assembled on the bottom surface A15; Z-direction pressing The screw A11 presses against the Z-direction positioning surface A16 for clamping and fixing; the Y-direction movable support B12 is assembled on the fixture body and the bottom surface B20; the Z-direction pressing screw B13 presses against the Z-direction reference plane B21 for clamping and fixing. Another process is thereby fixed.

Referring to FIG. 7 , it shows a schematic view of the fixing plate for the two processes of clamping on the fixture of the present invention. It can be seen from the figure that each fixture clamps two fixed plate parts, and each station processes three surfaces of the fixed plate, so the processing time of these two stations is basically the same or similar. After the processing is completed, the two processes are reversed to complete the processing of the corresponding other process, and the efficiency is greatly improved.
