Specific embodiment

In conjunction with attached drawing, the utility model is described in further detail.This specific embodiment is only to the utility model Explanation, be not limitations of the present invention, those skilled in the art, can be according to need after reading this specification The modification of not creative contribution is made to the present embodiment, but as long as in the scope of the claims of the utility model all by The protection of Patent Law.

Embodiment 1: as depicted in figs. 1 and 2, a kind of fixture, including with angle index pedestal 1, along pedestal 1 individually turn Two dynamic pivoted arms 2 and the clamping device 3 that 2 end of pivoted arm is arranged in, the pedestal 1 are equipped with locking member 4.Two pivoted arms 2 one end is rotatably installed on the pedestal 1 and is locked in turned position by same locking member 4, and clamping machine is arranged in the other end Structure 3.At least one end face paste of pivoted arm 2 leans against on the pedestal 1, at least sticks on one side on the end face of another pivoted arm 2, pivoted arm 2 are equipped with the through-hole for observing the graduation mark positioned at turned position.

Clamping device 3 includes backup plate 32, the clamping plate 31 of 32 one end of backup plate is arranged in, the installation of 32 other end of backup plate is arranged in Plate 33, the collet 34 being arranged between clamping plate 31 and mounting plate 33 and the feeding part 35 for pushing collet 34 mobile, the clamping plate Perpendicular to the plate face of the backup plate 32, the feeding part 35 is mounted on the mounting plate 33 31 plate face, and pushes the folder First 34 move along the board direction perpendicular to the clamping plate 31, and the collet 34 is made to clamp gripped object with the clamping plate 31.Into It is puller bolt to part 35, the puller bolt is screwed on the mounting plate 33, and the axis of puller bolt is perpendicular to the folder The plate face of plate 31, the collet 34 are fixed on the end of the puller bolt.

The line of two ends of the plate face of clamping plate 31 and the pivoted arm 2 forms angle α, and angle α size is 45 °, makes to press from both sides It holds mechanism 3 to be inclined on pivoted arm 2, the inclined direction of the clamping device 3 on two pivoted arms 2 is on the contrary, i.e. two pivoted arms 2 are in When on same straight line, the axis intersection of two puller bolts.

Locking member 4 is clamping screw, and the clamping screw is screwed on the pedestal 1, and the clamping screw is equipped with lock Tight piece, lock sheet are fixed on the clamping screw, two pivoted arms 2 be clamped in the pedestal 1 and the lock sheet it Between.

Embodiment 2: difference from Example 1 is that collet 34 is rotatably installed in the puller bolt, and along the top The axis rotation of tight bolt is just able to achieve feeding by rotation, is holding out against process since puller bolt is screwed on mounting plate 33 In puller bolt is rotated, and collet 34 does not rotate, and prevents collet 34 from rotating relative to clamped part and damaging clamped part table Face.

Embodiment 3: place unlike the embodiments above is, lock sheet is set on the clamping screw and relatively described Clamping screw rotation, during locking, clamping screw is rotated relative to lock sheet, and lock sheet remains stationary, this to guarantee Pivoted arm 2 will not be driven to rotate because lock sheet rotates during locking, influence positioning accuracy.
