Universal clamp for machining pin holes of ball-head screws

Abstract

The invention discloses a universal clamp for machining pin holes of ball-head screws. The universal clamp comprises a drilling die bracket arranged on the right end surface of a V-shaped base, wherein a drilling sleeve is embedded into a hole on the drilling die bracket; a drilling die is arranged in a hole of the drilling sleeve; the right end surface of the V-shaped base is provided with a key groove which is internally provided with a guide key by a fixed bolt; the center line of the key groove is consistent to the center of a V-shaped surface; the right end surface of the V-shaped base is also provided with a ball bowl which is provided with a handle; the ball surface of the ball bowl is matched with the ball surfaces of the top ends of the ball-head screws, and the other surface of the ball bowl is matched with the inner side surface of the drilling die bracket; the center of the drilling die bracket is provided with a vertical U-shaped through groove which is matched with the guide key. The universal clamp disclosed by the invention has the advantages that the pin holes of the ball-head screws with different specifications are conveniently machined, the production accuracy is improved, the production cost is reduced, the production efficiency is improved, the phenomena of wearing, chip falling and burning in use of the ball-head screws are effectively avoided, and the production need is met.

Description

technical field [0001] The invention relates to a universal fixture, in particular to a universal fixture for processing the pin hole of a ball screw. Background technique [0002] In the design of the sealing height adjustment mechanism of the press, it is a common practice to use the dial pin to drive the ball screw to rotate to adjust the sealing height. In the production process, once there is a deviation in the processing of the pin hole of the ball screw, the ball sleeve driving the pin will deflect and interfere with other parts. In addition, the processing of the pin hole is usually drilled by a drilling machine after scribing, or processed by a boring and milling machine after alignment. The former has low precision, and the latter has a large cost and low efficiency in mass production. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a universal jig for processing ball screw pin h...

AI Technical Summary

Problems solved by technology

In the production process, once there is a deviation in the processing of the pin hole of the ball screw, it will cause the ball sleeve that drives the pin to deflect and interfere with other parts.

In addition, the processing of pin holes is often drilled with a drilling machine after scribing, or processed after alignment with a boring and milling machine. The former has low precision, and the latter costs a lot. In mass production, the efficiency is low.
