Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1 to 3, a lathe clamping tool for flanges comprises a base 1 connected with a lathe bed 17. The base 1 is provided with a push block 2, the bottom of the push block 2 is provided with a lug 15, and a return spring 16 is arranged between the lug 15 and the inner wall of the base 1. Lifter 4 in the middle of the

ejector pad

2, 4 tops of lifter have cup jointed briquetting 3, briquetting 3 is connected with

ejector pad

2, 4 bottoms of lifter are connected with actuating mechanism, the other supplementary fixed block 8 that is equipped with of base 1, the 8 lower extremes of supplementary fixed block inlay in bed board 17 and link block 18, slider 18 cup joints on translation pivot 10, the other translation motor 13 that is equipped with of translation pivot 10, translation pivot 10 and translation motor 13 pass through translation gear 12 meshing and connect.

The driving mechanism is arranged in the lathe, a threaded rod 5 of the driving mechanism is arranged below a lathe bed plate 17, the top end of the threaded rod 5 is embedded into the lifting rod 4, the lifting motor 7 is arranged beside one end of the threaded rod 5, the threaded rod 5 is connected with the lifting motor 7 through the lifting gear 6, and the other end of the threaded rod 5 is provided with a limiting block 11. Translation pivot 10 and translation motor 13 are established on lift backup pad 9, and translation pivot 10 is equipped with two and connects through chain 14, and chain 14 cup joints on translation motor 12.
