Description

technical field [0001] The invention belongs to the technical field of precision machinery manufacturing, and in particular relates to a grinding device used for mechanical grinding and obtaining high machining accuracy. Background technique [0002] In mechanical processing, grinding technology has developed rapidly. From traditional manual grinding, various types of grinding machines have been developed, which have replaced manual labor to a certain extent and met the grinding requirements of small and medium-sized parts. Like manual grinding, it is qualitative grinding. For large and heavy parts and large planes, the finishing of such parts still adopts the traditional processing idea. After the rough machining and semi-finishing of large-scale equipment, the finishing is completed by manual local repairing. Because it is a qualitative correction , there are blindness and human factors, the accuracy is difficult to improve. Quantitative grinding technology has been well...

Problems solved by technology

The axial reciprocating motion of the rotation shaft of the planetary wheel type CNC grinding and polishing removal function generator adopts sliding series motion, and the sliding friction resistance of the reciprocating motion is affected by the transmission torque and the roughness of the contact surface. Reduced reciprocating sensitivity, which reduces the stability of the removal function

In addition, the strict translation of the rotation shaft system during the revolution process is constrained by two sets of vertically arranged swing rods. The swing rods are hinged with the transition plate, the retaining seat, and the slewing seat to ensure the translation of the slewing seat during the revolution movement. Supporting gravity, asymmetric restraint force, reducing the stability of revolution motion and dynamic stiffness of the system
