Problems solved by technology

However, this kind of grinding operation is usually manual, and the efficiency is extremely low. The coaxiality of the inner spline and the outer spline of the spline pair cannot be guaranteed, and it can only be carried out on small-sized and light-weight parts. When the workpiece is large and relatively When heavy, manual grinding cannot be achieved

Abstract

The invention provides a pneumatic spiral spline grinding device which is characterized in that a static ground workpiece is fixed with a grinding workbench, another ground workpiece is connected with a reciprocating mechanism, a cylinder body is fixed on the workbench, and a cylinder piston rod is connected with the reciprocating mechanism; the motion coaxiality between the reciprocating motion mechanism and the workbench is guaranteed through the guide mechanism, and the air cylinder reciprocates up and down under the control of the pneumatic control system. A tension spring mounting bracket is fixed on the workbench, four tension springs can be mounted, one end of each tension spring is fixed on the tension spring mounting bracket, and the other end of each tension spring is fixed on a workpiece which reciprocates up and down; the pressing force of the ground tooth surfaces of the internal and external spiral splines is improved, and the grinding efficiency is improved.

Description

technical field [0001] The present invention relates to helical spline grinding. Specifically, it refers to a pneumatic grinding device for grinding large-size helical splines to improve the tooth surface finish and the contact ratio of the paired spline teeth. [0002] technical background [0003] The synchronous automatic clutch is a tooth clutch with high power density and high reliability that automatically engages and disengages depending on the input and output speed changes, and the helical spline is the key structure for the synchronous automatic clutch to generate spiral motion and transmit torque. The tooth surface finish and mating spline tooth contact ratio will affect the sliding smoothness of the synchronous automatic clutch sliding part and the load distribution when the helical spline transmits torque. At present, the common processing methods of helical splines are profile grinding and gear shaping. When the part has a large enough space for helical spline...
