Description

Technical Field

[0001] The present application relates to the technical field of processing jigs, and in particular to a processing jig for automobile connectors. Background Art

[0002] Automotive connectors play a vital role in modern industry, particularly in the automotive manufacturing sector. They must possess not only excellent mechanical properties but also high precision and stability. With the continuous advancement of automotive manufacturing processes, higher requirements are being placed on the machining accuracy of connectors to ensure the overall performance and safety of the vehicle. Therefore, improving the precision and stability of connector machining has become a key issue that needs to be addressed in the automotive manufacturing sector.

[0003] Utility Model Patent Publication No. CN220658972U discloses a stamping-resistant automotive die. The top of the lower die base is securely connected to a guide post, while the upper die base slides along the outer periphery of the guide post. A connecting block is fixedly mounted on the top of the upper die base, which is further connected to a hydraulic rod via this connecting block. A precision stamping mechanism is integrated within the lower die base. The workpiece is positioned above a positioning plate and precisely positioned by positioning posts and positioning blocks, effectively preventing any potential displacement or misalignment. When the hydraulic rod is activated, the upper die base moves downward to perform the stamping operation. After stamping is complete, the elastic force of the first spring pushes the positioning plate, along with the completed workpiece, upward, enabling rapid workpiece removal. The sliding post and second spring work together to provide the necessary cushioning protection for the upper die base. The second spring can be easily replaced and maintained by rotating the handwheel and threaded ring. However, installing a cushioning structure on the outside of the positioning plate only cushions external components such as the positioning plate, but not the internal workpiece. This can easily lead to inaccurate machining under rapid impact. Summary of the Invention

[0004] The purpose of this application is to provide a jig for machining automobile connectors, in order to solve the problem of inaccurate machining caused by the inability of the buffer structure to buffer the workpiece.

[0005] The present application provides a jig for processing automobile connectors using the following technical solutions:

[0017] Optionally, the mounting seat is further provided with a plurality of first positioning rods, which pass through the lower mold base and penetrate into the lower mold.

[0018] By adopting the above technical solution, since the processing jig usually only fixes the mounting seat, multiple first positioning rods can ensure the stability of the relative positions between the mounting seat, the lower die seat and the lower mold, thereby ensuring that the upper die seat and the upper mold pressed from above can be accurately pressed together, thereby improving the accuracy of processing.

[0019] Optionally, the lower die base is further provided with a second positioning rod, and the second positioning rod penetrates into the upper die base.

[0020] By adopting the above technical solution, since the upper mold and the lower mold are respectively installed in the upper mold base and the lower mold base, when the upper mold base is pressed against the lower mold base, the positioning rod is provided to make the positioning between the upper mold and the lower mold more precise, thereby effectively improving the stability and processing accuracy of the processing jig during use.

[0021] Optionally, a connecting plate is further included, which is arranged on the upper side of the upper mold base and has a connecting ring for connecting to an external mobile device.

[0022] By adopting the above technical solution, the connecting plate is arranged on the upper side of the upper die seat and has a connecting ring for connecting to an external mobile device, which facilitates the movement and positioning of the entire fixture and improves the operational convenience and precision during the processing.

[0023] Optionally, the upper mold further includes a positioning piece, the lower mold has a positioning groove, the positioning piece fits into the positioning groove, the positioning piece has a connecting rod, and the connecting rod passes through the upper mold and the upper mold base.

[0024] By adopting the above technical solution, the positioning part fits into the positioning groove. Before closing the upper mold and the lower mold, the positioning part is first set on the lower mold, and then the upper mold and the upper mold base are passed through the connecting rod of the positioning part to ensure that the upper mold and the upper mold base are accurately connected when connecting the lower mold and the lower mold base, further enhancing the stability of the pressing, thereby improving the processing accuracy and product quality.

[0025] Optionally, the upper die base is provided with a fixing piece, the fixing piece connects the connecting rod and the upper die base, and the connecting ring passes through the connecting plate to expose the fixing piece.

[0026] With this technical solution, since the positioning member is not attached to the lower mold, once processing is complete, the connecting rod and upper mold base are connected via the fixing member, allowing the connecting member to be removed along with the upper mold and upper mold base, preventing the positioning member from falling off and affecting the processed product. The connecting ring exposes the fixing member, allowing the operator to secure the connecting rod through the connecting plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The upper mold includes a processing block, a pressing part and an elastic part. The processing block can be detachably arranged in the upper mold. The pressing part is arranged in the upper mold and contacts the processing block.
