Description

Technical Field

[0001] The utility model relates to the technical field of bearing bush processing, in particular to a bearing bush drilling fixture. Background Art

[0002] The bearing shell is divided into a semi-cylindrical bearing shell with a shell shape and a cylindrical bearing shell with a ring-shaped longitudinal section. When the sliding bearing is working, a very thin oil film is required between the bearing shell and the rotating shaft for lubrication. If the lubrication is poor, there will be direct friction between the bearing shell and the rotating shaft, and the friction will generate very high temperature. Although the bearing shell is made of a special high-temperature resistant alloy material, the high temperature generated by direct friction is still enough to burn it, so the oil injection hole needs to be processed on the annular surface of the bearing shell.

[0003] After searching, the patent document with application number CN202022312206.1 discloses an adjustable clamping device for bearing processing, including a fixed frame, the right side of the fixed frame is movably connected to a rotating shaft with one end passing through and extending into the interior of the fixed frame, the left side of the rotating shaft is fixedly connected to a movable frame movably connected to the left inner wall of the fixed frame, the right side of the fixed frame is fixedly connected to a fixed plate, and the bottom of the fixed plate is movably connected to a worm gear.

[0004] In the above-mentioned prior art, although the movement of the inner plate and the outer plate can be controlled by the bidirectional studs and the screw, and the bearing can be clamped and fixed, the rotation of the bidirectional studs and the screw needs to be manually controlled, which is rather troublesome. In addition, when drilling holes in the bearing, there are no corresponding auxiliary drilling measures. When the staff uses a drilling machine to drill holes in the annular surface of the bearing, it is easy to cause deviation. Therefore, a bearing drilling fixture is now proposed.
