Description

Technical Field

[0001] The utility model relates to the technical field of differential housing processing, in particular to a differential housing grinding device with a tightening structure. Background Art

[0002] The car differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right half-shaft gears, two planetary gears and a gear rack. Its function is to make the left and right wheels roll at different speeds when the car is turning or driving on uneven roads, that is, to ensure that the drive wheels on both sides perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels, and the differential housing needs to be polished during the production process.

The utility model pulls the two groups of arc plates closer to move the case. The body is sleeved between the two groups of arc plates, and the first spring reset pushes the two groups of arc plates to press against the inner wall of the shell, and then presses the shell downward to abut against the top of the fixed column, so that the shell can be fixed more conveniently and grinding is convenient; the above-mentioned existing technical scheme has the following shortcomings: during the use of the grinding device, the arc plate on the cross plate cooperates with the spring to clamp the differential housing.

Therefore, it is necessary to design a differential housing grinding device with a clamping structure to solve the above problems. Utility Model Content
