Description
Technical Field
[0001] The utility model relates to the technical field of positioning fixtures, in particular to a differential housing clamping device. Background Art
[0002] The differential housing is the housing that contains the planetary gears in the main reducer. The differential housing plays the role of supporting, connecting, and transmitting torque, so it has high requirements for strength, plasticity, and toughness, so cast iron materials need to be selected. During the production and processing of the differential housing, for example, after the differential housing is machined, it needs to be deburred, so the differential housing needs to be clamped and positioned to ensure the stability of the differential housing during the manual deburring process.

[0006] The beneficial effects of the utility model are as follows: through the setting of the hydraulic cylinder, the support height of the support platform can be adjusted, the clamping position of the differential housing can be adjusted, and then the differential housings of various sizes can be clamped accordingly. When the clamping outer plate gradually approaches the differential housing under the drive of the linkage side plate, the protective inner pad approaches synchronously until the protective inner pad is tightly fitted with the differential housing. The three clamping outer plates approach the center synchronously to clamp and fix the differential housing, and the fit of the protective inner pad with the differential housing is used to prevent the differential housing from moving.

[0014] As a further improvement of the above technical solution: the sliding cross bar is slidably connected to the positioning ring, and the outer ring diameter of the positioning ring matches the outer ring diameter.
[0015] The beneficial effect of this improvement is that under the transmission action of the ring gear, the other two bevel gears drive the corresponding adjusting screws to rotate, thereby causing the other two movable side plates to move synchronously, so that the three movable side plates can be closed and approached to the center synchronously, and the differential housing can be clamped and fixed.

[0023] As a further improvement of the above technical solution: the clamping outer plates are arranged in an arc-shaped structure and three of them form a group, and the three clamping outer plates in the same group are arranged equidistantly around the circumference.
[0024] The beneficial effect of this improvement is that during the rotation of the adjusting screw, the movable side plate is driven to move toward the center of the positioning ring, thereby moving the three movable side plates synchronously. At the same time, during this process, the movable side plate drives the sliding cross bar and the linkage side plate to move.
[0025] To clamp and fix the differential housing:
[0026] As a further improvement of the above technical solution: one end of the clamping outer plate away from the linkage side plate is connected to a protective inner pad, and the protective inner pad is a rubber pad with an arc-shaped structure.

The three clamping outer plates approach the center synchronously to clamp and fix the differential housing, and the fit between the protective inner pad and the differential housing is used to prevent the differential housing from moving.
