Description

Technical Field

[0001] The utility model relates to the technical field of oil-containing bearing processing, in particular to a clamping device for oil-containing bearing processing. Background Art

[0002] As we all know, oil-containing bearings, that is, porous bearings, use metal powder as the main raw material. Oil-containing bearings are sintered bodies made by powder metallurgy. They are inherently porous and have technical advantages such as the number, size, shape and distribution of pores can be adjusted more freely during the manufacturing process.

[0003] After production, oil-containing bearings often need to be clamped again for deburring to ensure the stability of product use. When deburring different parts, for example, when deburring the end face, only the grinder needs to be rotated, and when rounding and deburring the side edges, the material needs to be rotated. The traditional clamping device cannot meet the corresponding needs, nor can it adjust the height of the material being clamped to reserve processing space for the product, which makes it inconvenient to use.

The two groups of clamping blocks 8 threadedly connected to the positive and negative thread screws 6 move toward each other under the limit of the slide groove. The clamping blocks 8 stably clamp the material in the center. The height at which the material is clamped can be adjusted by the lifting assembly. When the material needs to be rotated, start the motor 2, and the motor 2 drives the turntable 4 to rotate.

[0023] In actual use, it is often necessary to stably fix the material. For this purpose, a locking part for fixing the turntable 4 is also provided on the workbench 1.
