Setting adjusts mobile and locking right retaining mechanism 1, right sleeve 2, right screw 3, middle locking in centre frame lower body 17
Mechanism 4, middle screw rod 5, middle sleeve 6, left retaining mechanism 12, left screw 13, left sleeve 14,.It is arranged in centre frame upper body 21 and adjusts
Mobile and locking upper retaining mechanism 23, upper screw rod 24, upper bush 25.By upper between centre frame upper body 21 and centre frame lower body 17
Lower body connecting shaft 19 and bolt 22 connect.
Oil cylinder 18 connects centre frame upper body 21 by oil cylinder connecting shaft 15, oil cylinder connecting shaft 20 and is mounted on centre frame lower body
Oil cylinder connecting bracket 16 on 17.Centre frame lower body 17 is fixed on lathe bed by the first and second pressing plate 7,11.
As shown in Fig. 2, cylinder body 33 is connect with flange 31 and is mounted on upper bush by screw 32, butterfly by screw 29
Spring 30 is sleeved on piston 28, and sliding shoe 26 is connected with straight pin 34 with piston 28 by screw 27 forms elastic clamping machine
Structure.
Working principle: when clamping workpiece, release bolt 22, starting oil cylinder 18 pulls centre frame upper body 21, surrounds upper lower body
Connecting shaft 19 is rotated to required position.Be packed into workpiece, rotation right screw 3, left screw 13, middle screw rod 5 come adjust right sleeve 2, in
