AI Technical Summary

Technical Problem

The screw hole processing of existing mallet heads has problems of low accuracy and poor safety, especially the cylindrical mallet heads are difficult to fix, resulting in inaccurate processing.

Method used

A cylindrical mallet head connecting screw hole drilling device is designed to achieve limiting the tap head through the horizontal induction part and the induction end of the proximity switch, ensuring the accurate machining depth of the threaded hole. At the same time, the placement of grooves and elastic anti-slip layer are used to clamp the mallet head to improve the safety and accuracy of processing.

Benefits of technology

The accuracy and safety of threaded hole processing are improved, ensuring the close connection between the hammer head and the rod body, and improving the reliability of assembly.

Abstract

The utility model discloses a cylindrical mallet head connecting screw hole drilling device which comprises a drilling machine and a machine frame, the drilling machine is located behind the machine frame, and a main machine of the drilling machine is located over a top plate of the machine frame. A cylindrical containing block is fixed to the middle of the top face of a top plate of the rack, a containing groove is formed in the middle of the top face of the cylindrical containing block, the left end and the right end of the containing groove extend out of the left side wall and the right side wall of the cylindrical containing block, and the inner wall face of the containing groove is an arc-shaped wall face. The outer side wall of the lower part of the mallet head is pressed against and matched with the inner side wall of the placing groove; the lifting of the screw tap head is limited through the approach of the horizontal induction part and the induction end of the proximity switch, the accuracy of the machining depth of a threaded hole is guaranteed, the machining accuracy is guaranteed, meanwhile, a cylindrical mallet head can be clamped and fixed, machining is convenient, and the safety is improved.
