Description

Technical Field

[0001] The utility model relates to the field of clamping mechanisms, and particularly relates to a feeding clamping mechanism for a needle roller bearing support bushing. Background Art

[0002] The needle roller bushing includes a support bushing. In the manufacturing process of the support bushing, there is a process of polishing its inner wall. Before polishing the support bushing, it is necessary to fix the support bushing first, and then drive the support bushing to rotate synchronously under the rotation of the clamping mechanism. In an existing technology, the clamping mechanism includes a clamping cylinder and a clamping block. The clamping cylinder drives the clamping block to move, so that the clamping block clamps and fixes the support bushing. However, this clamping mechanism only has a primary clamping component. The so-called primary clamping component means that the clamping range of the clamping block is small, and there is only one clamping block distributed on the periphery of the base. However, it cannot clamp the support bushing with a larger diameter, thus restricting the application range of the clamping mechanism to a certain extent. Summary of the Invention
