Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling for processing holes of an upper connecting plate. Background Art

[0002] The upper connecting plate is a mechanical connecting component. During processing, corresponding parts of the connecting plate will be drilled and expanded for connection and installation.

[0003] The traditional processing method is to place the upper connecting plate on the positioning plate of the fixture, and then set the angle cylinder and clamping plate at different external force points. After the angle cylinder is activated, the clamping plate is driven to press down to clamp the workpiece, and then drilling and expanding are carried out.

[0004] The above processing method has the problem that the workpiece cannot be fully positioned when expanding the hole, that is, it is only pressed and clamped at some points. When drilling, the workpiece is easily moved by the force, thereby reducing the product processing accuracy. At the same time, after the drilling process, most of the iron chips fall directly on the positioning plate, which easily causes the accumulation of iron chips. During the rotation of the drill bit, it is easy to hit the iron chips, causing splashing, and easily causing scratches on the workpiece surface, which also greatly reduces the product processing accuracy and is not conducive to production and processing use.

[0007] The auxiliary device includes a base, an upper die base and an auxiliary block. The base is fixedly connected to the lower die base and is located at the bottom of the lower die base. The base has a blanking cavity, which is located on one side of the base. The upper die base is located above the lower die base. The upper die base has a matching cavity, which is located on the upper die base.
