Description

Technical Field

[0001] The present invention relates to the technical field of oil pump accessory processing, and particularly relates to a grinding device for processing an oil pump housing. Background Art

[0002] During the processing of an oil pump housing, in order to ensure the surface accuracy of the oil pump housing, it is usually necessary to grind the surface of the oil pump housing. In order to facilitate the grinding of the oil pump housing, workers usually use a grinding device to grind the oil pump housing. The existing grinding device usually consists of an oil pump housing grinding box, an oil pump housing grinding seat, a driving motor, a pressing plate, a driving cylinder, and a grinding disc.

[0003] For example: The utility model with the application number CN202222246819.9 discloses an oil pump housing grinding device. The present utility model belongs to the technical field of grinding devices, and specifically discloses an oil pump housing grinding device. A recovery bin is fixedly connected to the inner cavity side wall of the housing through bolts. A pump machine is fixedly connected to the top of the recovery bin through screws. An auxiliary frame is fixedly connected to the side wall of the recovery bin through bolts. A grinding driver is fixedly connected to the side wall of the auxiliary frame through bolts. A lifting rod is inserted into the output end of the grinding driver. A grinding wheel disc is fixedly connected to the bottom of the lifting rod through screws. In this oil pump housing grinding device, through the combined use of accessories, a grinding driver carrying a grinding wheel disc is arranged inside the housing. After grinding, a pumping pipe with a porous plate is used to transfer grinding debris, and a sound reduction filter cylinder is arranged on the elbow pipe to facilitate noise reduction processing of the pumping noise entering the recovery bin by using the sound reduction filter cylinder.

[0004] However, when grinding an oil pump housing, it is usually necessary for workers to first place the oil pump housing to be ground on the oil pump housing grinding seat, and then fix the oil pump housing by adjusting the position of the pressing plate. After grinding, the position of the pressing plate is adjusted again to release the fixation of the oil pump housing. However, during the process of grinding a large number of oil pump housings, the operator needs to continuously repeat the operations of fixing and releasing the fixation of the oil pump housing, that is, frequently adjusting the position of the pressing plate will affect the grinding efficiency of the oil pump housing, and the operation is relatively cumbersome and inconvenient to use.
