[0002] The bearing shell is the contact part between the sliding bearing and the journal, and its shape is a semi-cylindrical shell. During the width processing of the bearing shell, it is necessary to load the bearing shell into the work station of the mold turntable through the width mold, and then push the bearing shell to the reference surface by the position adjustment device relatively arranged on the two end surfaces of the mold turntable, so as to ensure the accuracy of the bearing shell in the subsequent width cutting process and make the bearing shell reach the target width.

[0003] In the process of the position adjustment device pushing the bearing, the position adjustment device on one side pushes the bearing first, and the pushing surface of the position adjustment device is the reference surface. The bearing will deviate from the reference surface due to the thrust and inertia, so the position adjustment device on the other side needs to correct the bearing. However, in actual applications of the existing position adjustment device, the position adjustment device on the other side often applies too much thrust to the bearing, causing the reference surface to retreat, thereby causing the bearing to deviate, reducing the accuracy and processing quality of the bearing cutting, and making it difficult to achieve accurate correction of the bearing.

The first straight groove 4 and the second straight groove 5 are respectively connected to the two ends of the arc groove 3.

[0045] The transmission mechanism includes a follower and a push plate 6. The follower is divided into a follower rod 7 and a push rod 8 from bottom to top. The follower rod 7 is embedded in the arc groove 3 so that it can be moved by the cam 2. The first straight groove 4 and the second straight groove 5 are both used to limit the follower rod 7. One end of the push rod 8 passes through and exceeds the first side of the support frame 1, and is used to connect the push plate 6. The push plate 6 is used to push the bearing.

[0046] In a specific embodiment, the support frame 1 is an iron frame structure.

[0047] In one embodiment, the driving assembly includes a connecting shaft 9, a rocker arm 10 and a cylinder connecting head 11, the connecting shaft 9 is connected to one end of the cam 2 and extends to a second side of the supporting frame 1 opposite to the first side, the rocker arm 10 is sleeved on the connecting shaft 9 on the second side of the supporting frame 1, and the cylinder connecting head 11 is arranged on the rocker arm 10 for connecting to an external cylinder.

[0048] Specifically, when the cylinder connecting head is connected to the external cylinder, the external cylinder can drive the cylinder connecting head to move downward and drive the rocker arm to rotate counterclockwise, thereby driving the cam to rotate. At the same time, the follower rod can move with the rotation of the arc groove, thereby driving the push rod and the push plate to move, so that the push plate approaches and pushes the bearing.

[0054] When the position adjustment device of the utility model is in use, the position adjustment device is first installed to the specified position through the installation groove and the adjustment mechanism, and then the external cylinder is started to drive the cam to rotate and synchronously drive the driven rod and the push rod to move, so that the push plate pushes the bearing shell, and then the driven rod is clamped in the second straight groove.

[0055] The position adjustment device for bearing processing proposed by the utility model has an arc groove on the cam, and a driven rod is embedded in the arc groove, so that the driven rod can move following the rotation of the cam, so that the push rod drives the push plate to move, so as to realize the correction of the bearing.
