Description

Technical Field

[0001] The utility model belongs to the technical field of differential processing and relates to an online turning mechanism for a differential housing. Background Art

[0002] When assembling the differential, the differential case is positioned online, and then the half-shaft gears are installed. After the differential case is flipped, the planetary gears are installed one by one from the other side of the differential case. At present, online assembly is mainly completed manually by flipping the differential case. Manual flipping of the differential case is not only laborious (the differential case is heavy), but also its position will change after flipping and putting it back, which is not conducive to assembly efficiency and continuity of online manual assembly. Utility Model Content

[0003] The purpose of the utility model is to provide an online turning mechanism for a differential housing in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to complete the online in-situ turning of the differential housing.

[0004] The purpose of the utility model can be achieved through the following technical solutions: an online turning mechanism for a differential housing, characterized in that it includes a linear motor 1 fixed on a frame, a mounting frame fixed on an output shaft of the linear motor 1 and a clamping assembly arranged on the mounting frame, the clamping assembly includes a bidirectional cylinder and two clamping blocks, the two push rods of the bidirectional cylinder are both slidably connected to the mounting frame, a connecting arm is fixedly provided on the two push rods of the bidirectional cylinder respectively, a mounting rod is fixedly provided on the outer end of the clamping block, and the mounting rod is rotatably connected to the connecting arm through a bearing; a linear motor 2 is also fixedly provided on the mounting frame, two racks corresponding to the mounting rods are fixedly provided on the push rod of the linear motor 2, and the mounting rod has an outer gear ring that cooperates with the corresponding racks.

[0005] Linear motor 1 controls the longitudinal movement of the mounting frame, and moves it down to the position corresponding to the differential housing before the two clamps close, and then controls the two-way cylinder to make the two clamps close together to clamp the differential housing. Linear motor 1 controls the mounting frame to move up as a whole, and carries the differential housing up. After moving to a height where the differential housing will not interfere with the differential housing and the resting plane when the differential housing is flipped, linear motor 2 controls the rack to move horizontally, and then drives the clamp and the differential housing to flip. After flipping 180°, linear motor 1 controls the mounting frame to move down to the differential housing for rest, and finally controls the clamp to release the differential housing, thus completing the online flipping of the differential housing. This can greatly reduce the operating intensity for differential housings with heavier weights, and can also avoid the position offset of the differential housing after flipping caused by manual operation, making it more consistent to complete multiple processes online.

[0006] Furthermore, the housing of the bidirectional cylinder is fixed on a mounting frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0010] like Figure 1 The online flipping mechanism of the differential housing shown in the figure comprises a linear motor 1 fixed on a frame, a mounting frame 2 fixed on an output shaft of the linear motor 1 and a clamping assembly arranged on the mounting frame 2, the clamping assembly comprising a bidirectional cylinder 3 and two clamping blocks 4, the housing of the bidirectional cylinder 3 is also fixed on the mounting frame 2, the two push rods of the bidirectional cylinder 3 are both slidably connected to the mounting frame 2, a connecting arm 5 is fixedly provided on the two push rods of the bidirectional cylinder 3 respectively, a mounting rod 6 is fixedly provided on the outer end of the clamping block 4, and the mounting rod 6 is rotatably connected to the connecting arm 5 through a bearing; a linear motor 2 7 is also fixedly provided on the mounting frame 2, two racks 8 corresponding to the mounting rods 6 are fixedly provided on the push rod of the linear motor 2 7, and the mounting rod 6 has an outer gear ring that cooperates with the corresponding rack 8.

[0011] The linear motor 1 controls the longitudinal movement of the mounting frame 2, and moves down to the position corresponding to the differential housing before the two clamping blocks 4 are closed, and then controls the bidirectional cylinder 3 to make the two clamping blocks 4 close together to clamp the differential housing. The linear motor 1 controls the mounting frame 2 to move up as a whole, and carries the differential housing up. After moving up to a height where the differential housing will not interfere with the differential housing and the placement plane of the differential housing when the differential housing is flipped, the linear motor 2 7 controls the rack 8 to move horizontally, and then drives the clamping block 4 and the differential housing to flip. After flipping 180°, the linear motor 1 controls the mounting frame 2 to move down to the differential housing for placement, and finally controls the clamping block 4 to release the differential housing, thereby completing the online flipping of the differential housing. The operating intensity can be greatly reduced for the differential housing with a heavier mass, and the position offset of the differential housing after flipping caused by manual operation can be avoided. Multiple processes can be completed online more continuously.

[0012] In this way, the linear motor 1 can be located on one side of the working line, that is, the other side of the differential housing conveying line away from the operating side of the operator.

[0013] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
