AI Technical Summary

Technical Problem

Existing grinding equipment has unstable clamping when fixing screwdriver blanks, resulting in reduced grinding accuracy. In particular, the non-parallel state between the plane of the insert end and the line of the bit end causes the bit to be skewed when it contacts the grinding disc, affecting grinding accuracy.

Method used

The screwdriver head grinding machine adopts multi-station synchronous grinding. Through the combination design of clamping parts and support blocks, the screwdriver blank is pre-fixed and corrected by the drive unit and locking unit to ensure that the screwdriver blank maintains the accurate angle during the grinding process.

Benefits of technology

It improves the grinding precision and quality of screwdriver blanks, ensuring that the screwdriver blanks do not rotate during the grinding process, thereby improving grinding efficiency and accuracy.

Abstract

The invention discloses a multi-station synchronous grinding screwdriver head edge grinding machine, and relates to the technical field of screwdriver machining, the multi-station synchronous grinding screwdriver head edge grinding machine comprises a base, and a plurality of conveying mechanisms are arranged on the base; edge grinding mechanisms are arranged at the tail ends of the conveying mechanisms; the conveying mechanism comprises a moving frame which is installed on the top of the base in a sliding mode and used for conveying screwdrivers; the two supporting blocks are symmetrically arranged on the two sides of the moving frame in the conveying direction of the moving frame and located on the two sides of the screwdriver moving path. The supporting blocks are rotationally connected with clamping pieces used for fixing screwdrivers. The two positioning blocks are symmetrically arranged relative to the movable frame, positioning grooves are formed in the inner sides of the positioning blocks, and the inner contours of the positioning grooves are matched with the outer contours of screwdriver bits; the screwdriver blank can be located at an accurate angle when abutting against the edge grinding mechanism, and the grinding precision and quality of the screwdriver blank can be effectively improved.
