Description

Technical Field

[0001] The utility model relates to the technical field of differential housings, in particular to a differential housing clamping device. Background Art

[0002] The differential is an important part of the automobile transmission system. It allows the left and right wheels of the vehicle to rotate at different speeds to accommodate tire slippage and vehicle stability when turning. The differential housing is used to carry and protect the gears and mechanical devices inside the differential. In order to ensure that the differential remains stable during operation, users generally fix the differential housing with a clamping device.

[0003] The existing differential housing only has the function of carrying and protecting the gears and mechanical devices inside the differential, but does not fix the differential housing. In this case, it is impossible to ensure that the differential remains stable during operation, thus affecting the normal operation of the differential. In addition, since the clamping device only has the function of fixing the differential housing, it is impossible to fix the device itself, which may cause the clamping device to fall off or be misplaced, thereby affecting the operation of the differential.

[0004] Therefore, those skilled in the art provide a differential case clamping device to solve the problems raised in the above background technology. Utility Model Content

Since the threads on both sides of the bolt are opposite, the motor is turned on to make the bolt drive two bearings to move, and the two bearings drive four clamping columns to move, so as to fix the differential case. In addition, when the bolt rotates, it will drive the gear to rotate, and the gear will cooperate with the first control block and the clamping plate to fix the device, so as to prevent the device from falling when fixing the differential case, thereby causing damage to the device and the differential case.

[0021] Furthermore, the two push blocks are moved by the second control block, and the four clamping columns are moved between each other by the push blocks;

[0022] Through the above technical solution, the two second control blocks can drive the two push blocks to move, and the two push blocks will drive the four clamping columns to move while moving, thereby facilitating the fixation of the differential housing.
