Bolt, T shape screw rods include the T prefixs and screw rod of connection, and T prefixs are matched with T shape card slots, and screw rod is sequentially connected across kidney slot
There are washer and nut.
Further, the quantity of T shapes card slot is 3, and is arranged along the even circumferential of chuck.
Further, two long sides of kidney slot are arc.
Further, the side of chuck is circumferentially uniformly machined with 2~4 fixing screwed holes, the center of fixing screwed hole
Line along chuck radial direction, and fixing screwed hole in screw in have fixing bolt.
Further, the side of chuck is machined with rectangular through-hole, and inserted with datum plate in rectangular through-hole.
The utility model is provided with T shape card slots on chuck, and detent mechanism can slide in T shape card slots, so as to claw
Grasp workpiece, claw is slidably connected with locating piece, encounter to process larger workpiece when, two and half V-arrangement claws can pass through
Sliding rail is separated to both sides, the applicability that the present apparatus processes abnormal workpieces can be improved, in addition, machined kidney-shaped on locating piece
Hole, in the case where T shape screw rods are motionless, locating piece can be moved left and right, and to change the position of claw, search out workpiece
Upper convenient for positioning and fixed position, the utility model is reasonable for structure, easy to operate, and positioning is rapid, has significant economic valence
Value and social value.

The utility model will be further described below with reference to the accompanying drawings, but is not subject in any way to the utility model
Limitation belongs to the scope of protection of the utility model based on any changes and modifications made by the utility model introduction.
Embodiment
As shown in Fig. 1~Fig. 6, the utility model includes chuck 1 and detent mechanism, on chuck 1 processing there are one with chuck 1
Concentric circular through hole 2 is machined with T shapes card slot 3 radially on the end face of chuck 1, and the quantity of T shapes card slot 3 is 3~4, fixed
The quantity of position mechanism is identical as the quantity of T shapes card slot 3, and detent mechanism includes claw 4, locating piece 5 and T shapes screw rod 6, and claw 4 wraps
Two and half V-arrangement claws 7 are included, each half V-arrangement claw 7 is slidably connected by sliding rail 8 and locating piece 5, and in two and half V-arrangement claws
It is connected with spring 9 between 7, kidney slot 10 and threaded hole 11 are offered on locating piece 5, threaded hole 11 is connected to sliding rail 8, and in spiral shell
Being screwed in pit 11 has bolt 12, and T shapes screw rod 6 includes the T prefixs 61 and screw rod 62 of connection, and T prefixs 61 match with T shapes card slot 3
