Description

Fixing hole processing tooling for small cylindrical pins

technical field

The invention relates to a small straight pin, in particular to a machining tool for the fixing hole on the pin body of the small straight pin.

Background technique

One or two fixing holes are generally arranged on the pin body of the cylindrical pin for inserting the cotter pin to realize the positioning of the pin body. The fixing hole is drilled by a drilling machine, because the drill bit is easy to slip when drilling a hole on a cylinder and needs to be processed by a tooling. When processing the fixed hole on the cylindrical pin, because the cylindrical pin has many specifications and different thicknesses, even the positions of the holes required to be processed on the same type of cylindrical pin are not the same, resulting in various drilling tools for the pin body, resulting in processing costs High, on-site management is difficult.

Contents of the invention

The invention provides a pin body fixing hole processing tool for small cylindrical pins, which solves the technical problem that the machining tools for fixing holes on the pin bodies of various small cylindrical pins cannot be used in common.

The present invention solves the above technical problems through the following technical solutions:

The tail end of the sliding wall block is provided with a T-shaped plug joint, and the sliding wall block is installed through its tail end. The T-shaped plug-in connector is movably plugged in the T-shaped chute, and a threaded through hole for a jacking screw is provided on the sliding wall block, and a jacking screw is screwed in the threaded hole of the jacking screw, and the lower end of the jacking screw is connected to the On the pin column of the small cylindrical pin, a guide hole is set on the sliding wall block on the side of the screw thread through hole, a high-hardness wear-resistant guide sleeve is set in the guide hole, and a drill bit is set directly above the guide hole , A pre-processed pin body fixing hole is arranged directly below the guide hole, and the central axis of the threaded through hole of the top screw and the central axis of the guide hole are arranged parallel to each other.

A rotatable workpiece baffle is arranged on the L-shaped processing table outside one end of the V-shaped groove; threaded through holes for fixing screws are arranged on the sliding suspension wall block, and the fixing screws connect the vertical suspension wall block and the L-shaped processing table. The boards are fixedly connected together.

The present invention realizes the processing of the fixing holes at different positions on the pin body of the small cylindrical pin through the horizontal sliding of the sliding suspension wall block on the vertical plate of the L-shaped processing table. With the cooperation of different diameters, the clamping and processing of small cylindrical pins is realized, which has strong versatility, saves costs, facilitates production management, and improves processing efficiency.
