Detailed ways

The embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, but the utility model can be implemented in various ways defined and covered by the claims.

Referring to Fig. 1 and Fig. 2, the utility model provides a special-shaped fine polishing machine tool, including a frame base 1, a polishing unit 3 located on the frame base 1, and a workpiece spindle group 2; the workpiece spindle group 2 is used for clamping and fixing For the product to be polished, the polishing unit 3 is used to connect and adjust the position of the polishing wheel, and a single polishing unit 3 cooperates with a single workpiece spindle group 2 to polish the product.

Referring to Fig. 3 and Fig. 4, each group of polishing units 3 includes a first slider 6 at the bottom, a gantry 4 mounted on the first slider 6, a rotating central axis 7 horizontally running through the front and rear of the gantry 4, and a polisher main shaft 15 And the first motor 5 that drives the gantry 4 to move left and right and the cylinder mechanism 8 that drives the polishing machine main shaft 15 to move up and down.

The machine tool gantry 4 can swing left and right. The rod end bearing of the connecting rod eccentric wheel mechanism of the first motor 5 is connected to the first slider 6.
