Problems solved by technology

In the existing grinding device, since the diameter of the grinding rod is fixed, when grinding the step hole, in order to adapt to the change of the inner diameter of the step hole, the grinding rod needs to be replaced frequently. Finally, it is necessary to repeat the positioning of the grinding rod, which is not only time-consuming and laborious, but also difficult to ensure the grinding accuracy

Abstract

The invention discloses a polishing device for mechanical equipment parts, and belongs to the technical field of machining equipment. The polishing device for the mechanical equipment parts comprises a rack, a power device, a polishing rod, a controller and a power supply device, and further comprises a transmission shaft connected with the output end of the power device and provided with a first liquid through hole, and the first liquid through hole communicates with a hydraulic control loop; the adjusting mechanism comprises an annular plate and a plurality of adjusting pistons, the side wall of the annular plate is provided with a plurality of sliding holes in the radial direction of the annular plate, the sliding holes communicate with the first liquid through hole, one end of each adjusting piston is in sliding connection with one sliding hole, and the other end of each adjusting piston is connected with one polishing rod. According to the polishing device for the mechanical equipment parts, the inner walls, with different inner diameters, of stepped holes can be polished under the condition that the polishing head is not replaced, so that the time consumed for frequently replacing the polishing head is shortened, and then the polishing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a grinding device for mechanical equipment parts. Background technique [0002] In the later stage of the machining process, the surface of mechanical parts often needs to be ground to reduce the surface roughness to meet the requirements of the surface accuracy of the parts. Some parts have stepped hole structures. For assembly needs, the inner walls of these stepped holes will be ground. When grinding these stepped holes, a grinding rod is often required. [0003] Some existing devices for grinding step holes mostly include a frame, a power device, a grinding rod, a controller, and a power supply device. The controller is used to control the power device to drive the grinding rod to rotate, thereby grinding the stepped holes. In the existing grinding device, since the diameter of the grinding rod is constant, when grinding the stepped hole, in order to ...
