The finger claw and the claw tooth both comprise a left part and a right part. The two-finger synchronous cylinder drives the two fingers to move left and right simultaneously to realize the opening and closing of the fingers.
The reset mechanism comprises a stop block arranged on the outer frame and a reset block arranged on the finger claw, and the reset block and the stop block are arranged oppositely. After carrying out skew compensation, pneumatic fixture and manipulator are in non-centering position between the two, consequently should carry out the centering with position between them before the next clamp is got, remove about driving the finger claw through two finger synchronous cylinder, lean on the dog to carry out automatic centering through the reset block on the finger claw of both sides.
A sliding block and a linear sliding rail which are matched with each other are arranged between the pneumatic clamp and the outer frame, and the pneumatic clamp slides relative to the outer frame through the sliding between the sliding block and the linear sliding rail. The outer frame is fixed with a slide block, and the linear slide rail is fixed with a pneumatic clamp.
The locking mechanism is a clamping cylinder, a connecting plate is arranged on the pneumatic clamp, and one side of the connecting plate extends to a position between output ends of the clamping cylinder. The connecting plate is provided with a tooth-shaped structure for increasing friction. The locking mechanism is used for fixing the whole pneumatic clamp when the manipulator transports the workpiece, so that the sliding of the pneumatic clamp is avoided.
Compared with the prior art, the utility model has the beneficial effects that: the frame is used for being connected with the manipulator in this application, pneumatic fixture on the frame if press from both sides when the centre gripping work piece and get irregular work piece then can lead to pneumatic fixture both sides atress to have the time difference and produce for the frame and slide, thereby realize the compensation of central coordinate skew, thereby pneumatic fixture supports when opening before the secondary is got and leans on driving pneumatic fixture on the baffle simultaneously and adjust to frame central point and put, carry out the clamp of next time again and get, cycle in proper order, the tiny error that the above-mentioned process produced the product because of producing leads to central coordinate skew to compensate, guaranteed that the work piece can accurately place on next station after the transfer.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1, the coordinate offset compensation fixture comprises an outer frame 1 connected with a manipulator, wherein a pneumatic fixture is connected on the outer frame 1 in a sliding manner; the outer frame 1 is provided with a locking mechanism 5 for clamping the pneumatic clamp; the outer frame 1 is also provided with a resetting mechanism, and the resetting mechanism is used for resetting and centering the pneumatic clamp. Frame 1 is used for being connected with the manipulator in this scheme, pneumatic clamp on the frame 1 gets irregular work piece 01 when centre gripping work piece 01 if the clamp can lead to pneumatic clamp both sides atress to have the time difference, it has prior back to lead to two claw tooth contact work pieces, thereby bring whole pneumatic clamp part to the party of contact earlier, it just stops to contact the work piece until two claw teeth of cleft hand, and this only produces for frame 1 and slides, and the frame does not move, thereby realize the compensation of central coordinate skew, press from both sides the clamp at the secondary and get before and adjust pneumatic clamp to frame 1 central point through canceling release mechanical system, thereby carry out next clamp and get.
