Or the machine tool matching piece 16 is a trapezoid block, and the machine tool with the dovetail groove can be matched through the trapezoid block.

The base 1 is symmetrically provided with sliding grooves 5, a bearing seat 6 is arranged in each sliding groove 5, and a bearing roller 7 is arranged on each bearing seat 6. During processing, only the bearing pieces are required to be placed on the two sides of the carrier rollers 7. Meanwhile, the diameter and the length of the processed part are different, and the round bearing roller 7 can also well support the processed part, so that the accuracy in processing is ensured. And meanwhile, the dead weight of the part can be overcome so as to avoid deformation of the part.

In order to conveniently align the polishing main shaft of the polishing machine tool, a height adjusting device of a bearing roller 7 is additionally arranged. The bearing seat 6 comprises a T-shaped base 61 and a movable seat 62, the movable seat 62 is inserted into the T-shaped base 61, a push rod motor 63 is embedded and installed in the T-shaped base 61, and the output end of the push rod motor 63 is installed on the movable seat 62. In order to ensure the uniform height of the two side carrier rollers 7 so as to avoid the problem of polishing offset, the push rod motors 63 on two sides are connected with the same control terminal.

The T-shaped base 61 is slidably connected to the chute 5, and the backup roll 7 is disposed on the movable seat 62. The side wall of the T-shaped base 61 is provided with a slide block 8, a pair of slide block grooves 9 are formed in the slide groove 5, the slide block 8 is slidably connected to the slide block grooves 9, and a matching mechanism is arranged between the slide block grooves 9 and the slide block 8. The position adjustment and locking of the two side bearing brackets 6 can be completed through the matching mechanism, so that the height of the polished bearings is adjustable, and the shaft centers of the bearings with different diameters can be adjusted as required, so that the bearings are ensured to correspond to the main shaft of the machine tool.
