A gear grinding device that satisfies circumferential positioning in a pair of gear teeth

Abstract

The invention discloses a gear polishing device with gear alignment meeting the requirement of circumferential positioning. The gear polishing device structurally comprises a polishing body, clampingplates and a chassis, wherein the clamping plates are arranged on the periphery of the outer surface of the polishing body; the polishing body is fixedly welded onto the chassis; multiple grinding wheel grooves, a circular shaft and telescopic extension rods are arranged in the polishing body; the multiple grinding wheel grooves are formed; the four telescopic extension rods with same structures and sizes are welded onto the circumferential surface of the circular shaft; and a limited clamping ring, an auxiliary extraction piece and a grinding wheel are arranged on the inner side of the position, on which the inner wall of the polishing body is matched with each telescopic extension rod. According to the gear polishing device with gear alignment meeting the requirement of circumferential positioning provided by the invention, the four telescopic extension rods are matched with the circular shaft, a fan-shaped plate is arranged between each two telescopic extension rods, one clamping plate is matched between each two adjacent fan-shaped plates, the fan-shaped plates are identical, and automatic calibrating and positioning can be realized by utilizing the clamping plates, the circular shaft and the telescopic extension rods, so that the circumferential positioning is ensured to be accurate enough before gear polishing.

Description

technical field [0001] The invention relates to the field of gear manufacturing, in particular to a gear grinding device that satisfies circumferential positioning among gear pairs. Background technique [0002] With the development of science and technology in our country and the improvement of equipment level, the requirements for the precision of gear transmission parts are getting higher and higher, and high-precision gears with hard tooth surfaces have been widely used. As the mainstream core process equipment for high-precision, hard-tooth surface gear processing, the application of gear grinding machine tools is becoming more and more popular. Generally speaking, gear grinding is the tooth profile finishing process of gear parts. It is based on the completion of tooth profile rough machining (such as gear hobbing, milling, etc.) and heat treatment, etc., to remove the finishing allowance by grinding to further A tooth profile finishing process to improve gear precisi...

Problems solved by technology

[0003] If the circumferential positioning of the workpiece before grinding is inaccurate, the amount of grinding on both sides of the tooth groove will be uneven, and the serious grinding wheel will directly hit the tooth surface to wear the workpiece and even cause the loss of machine tool accuracy; and the circumferential positioning deviation will It directly affects the allowance of the tooth side of the subsequent grinding teeth, so the actual grinding gear must be considered according to the side with the larger allowance, resulting in an increase in the number of radial feeds, thereby reducing the processing efficiency
