Abstract

The invention discloses hobbing technological equipment for a cylinder body of a hydraulic motor and a clamping technology. A center of a top cover assembly is connected with one end of a gear hobbing machine compressing device. An elastic swelling base is fixed to a clamp body, and then the clamp body is connected with the other end of the gear hobbing machine compressing device. The cylinder body of the hydraulic motor is arranged on the elastic swelling base, and a connecting shaft is connected with a gear hobbing machine stretching device. A gear hobbing machine hydraulic system is started, the gear hobbing machine compressing device compresses the cylinder body of the hydraulic motor, and the connecting shaft is pulled downwards by the stretching device. The connecting shaft and a conical rod are drawn synchronously, the conical body section of the conical rod is made to stretch into the elastic swelling base, and the elastic swelling base is swelled open, so that an inner hole of the cylinder body of the hydraulic motor is tightly swelled. In this way, hobbing positional accuracy is effectively improved. According to the technological equipment, after the cylinder body of the hydraulic motor is clamped to a gear hobbing machine workbench, it can be guaranteed that in the hobbing process, radial run-out does not exceed 0.01 mm. Moreover, alignment time is short, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gear hobbing machine tool manufacturing technology equipment, in particular to a hydraulic motor cylinder gear hobbing technology equipment and a clamping process. Background technique [0002] The cylinder block is a very important part in the hydraulic motor, and the processing accuracy of its teeth directly affects the overall quality of the hydraulic motor. The accuracy of cylinder teeth is mainly related to motion accuracy, stability accuracy and contact accuracy. In gear hobbing, the motion accuracy is ensured by controlling the length of the common normal line and the radial runout of the ring gear, the stability of the work is ensured by the control of the tooth shape error and the base joint deviation, and the contact accuracy is ensured by the control of the tooth direction error. At present, gear hobbing is mostly manual clamping, which has the problems of low positioning accuracy, long alignm...
