Quick clamping jig for grinding machine of pin wheel housing tooth slot of robot joint precision reducer

Abstract

The invention discloses a quick clamping jig for a grinding machine of a pin wheel housing tooth slot of a robot joint precision reducer. The quick clamping jig comprises a guide pedestal and a workpiece clamp which is detachably fixedly arranged on the guide pedestal; and the workpiece clamp is used for positioning and clamping the outer wall of a pin wheel housing workpiece in a self-adaptive mode. The quick clamping jig utilizes the workpiece clamp capable of clamping the outer wall of the pin wheel housing workpiece in the self-adaptive mode, so that clamping of a workpiece is quick and convenient, and therefore, clamping and grinding efficiency is improved; and manufacturing cost is saved on the basis of guaranteeing product processing precision. The quick clamping jig can be applied to clamping pin wheel housing workpieces of the speed reducer and corresponding circular-ring-shaped workpieces.

Description

technical field [0001] The invention relates to the field of manufacturing pin gear housings of RV reducers, in particular to a fast clamping jig for a pin gear housing tooth groove grinder of a robot joint precision reducer. Background technique [0002] The RV reducer is an important core component of the robot, and the precision control of its production process directly affects the manufacturing cost and service life of the robot. Among them, the grinding process of the tooth groove of the pin gear shell is an important step in the manufacture of RV reducer. [0003] At present, most of the workpieces of this type of grinding machine in the world and in China are clamped manually and manually. This method is inefficient. It takes more than 10 minutes to clamp the workpiece at a time, which directly affects the pin teeth of the RV reducer. The production efficiency of shell tooth groove grinding; the early and current imported foreign grinding machines use the workpiece ...

Problems solved by technology

[0003] At present, most of the workpieces of this type of grinding machine in the world and in China are clamped manually and manually. This method is inefficient. It takes more than 10 minutes to clamp the workpiece at a time, which directly affects the pin teeth of the RV reducer. The production efficiency of shell tooth groove grinding; the early and current imported foreign grinding machines use the workpiece to be placed on the workpiece spindle rotating table, and then the center of the workpiece needs to be manually aligned gradually, and then manually locked and fixed

[0004] From this point of view, the existing domestic and imported machine tool fixtures have the advantages of simple structure, but the disadvantage is that the workpiece installation and clamping time is long, the efficiency is low, and the auxiliary time is too long, which directly prolongs the product processing time.
