Abstract

The invention discloses an inner curve grinding tool for a hydraulic motor shell and belongs to the field of mechanical machining. The inner curve grinding tool includes a motor shell fixture, a plurality of pads and a plurality of pressure plates, wherein the pads and the pressure plates are arranged in a complete set; the motor shell fixture is fixed on a working table of a curve grinding machine; the middle part of the motor shell fixture is provided with a convex platform matching a circular spigot on the end face of the hydraulic motor shell; the plurality of pads are arranged uniformly around the motor shell fixture in the circumferential direction of the motor shell, and each pad is fixed on the side wall of the motor shell fixture; and one end of each pressure plate is inserted into an oil port of the hydraulic motor shell, the other end of each pressure plate is pressed on the corresponding pad, and the middle part of each pressure plate is fixed on the motor shell fixture through a connecting member.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an inner curve grinding tool for hydraulic motor casings. Background technique [0002] Hydraulic motor is a common hydraulic component. In ship deck machinery, hydraulic motor is used to provide mechanical energy for equipment such as towing winch. [0003] The hydraulic motor mainly includes a hydraulic motor housing, rotor, motor shaft and blades. The inner surface of the hydraulic motor housing is an inner curved surface composed of multi-section curved surfaces. When the hydraulic motor is working, the blades are in contact with the inner curved surface of the hydraulic motor housing to realize the normal operation of the hydraulic motor. Therefore, the precision requirements for the inner curved surface are very high. [0004] When machining the inner curved surface, since the hydraulic motor housing is an irregular cylindrical part, it is not easy to clamp and fix the...
