Efficient relief-grinding mechanism

Abstract

The invention relates to an efficient relief-grinding mechanism. The efficient relief-grinding mechanism comprises a basal body, a motor mounting base, a swing body and a swing mechanism, wherein the motor mounting base is arranged at one side of the basal body, and is fixed relative to the basal body; a servo motor A is fixedly mounted on the upper part of the motor mounting base; the output end of the servo motor A is connected to a workpiece main shaft; the swing mechanism is arranged between the swing body and the basal body; the swing mechanism comprises a servo motor B, a cam, a roller, a large gear, a roller shaft and a swing arm; the servo motor B is mounted on the lower part of the motor mounting base, and is in transmission connection to the cam; the roller is pressed on the cam; the roller is in transmission connection to one end of the swing arm; a rotary shaft is rotatably mounted on the basal body; the rotary shaft is hinged with the other end of the swing arm; and the swing arm rotates around the rotary shaft. The efficient relief-grinding mechanism has the advantages that: the mass is small, high-frequency relief-grinding can be realized, the highest relief-grinding speed can be 6000 times / minute, the processing efficiency is high and the product quality is good; and the relief-grinding amount is regulated by regulating the position of a lever pivot, so that the spade shape of the Archimedes spiral is guaranteed to be unchanged.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to an efficient relief grinding mechanism. Background technique [0002] Thread grinding mostly adopts grinding head relief grinding, such as Drake linear motor thread grinding method adopts grinding head linear motor relief grinding, the relief grinding efficiency is about 1000 times / min; SB725G (multi-line) grinding head uses three-headed nut relief grinding, Relief grinding efficiency is about 600 times / min; SB725F (single wire) adopts servo motor (electronic cam) for relief grinding, and the relief grinding efficiency is about 600 times / min; due to the heavy grinding head frame, the inertia of relief grinding is large, so the relief grinding efficiency Low, affecting the efficiency of thread grinding, and the vibration of the grinding wheel affects the surface quality of the workpiece.

AI Technical Summary

Problems solved by technology

[0002] Most thread mills use grinding heads for relief grinding. For example, Drake linear motor thread grinding adopts grinding head linear motor for relief grinding, and the relief grinding efficiency is about 1000 times / min; SB725G (multi-line) grinding head uses three-headed nuts for relief grinding. Relief grinding efficiency is about 600 times / min; SB725F (single wire) adopts servo motor (electronic cam) for relief grinding, and the relief grinding efficiency is about 600 times / min; due to the heavy grinding head frame, the inertia of relief grinding is large, so the relief grinding efficiency Low, affecting the efficiency of thread grinding, and the vibration of the grinding wheel affects the surface quality of the workpiece
