Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not restricted by specific implementation.
The embodiments of the present invention are such：As shown in Figures 1 to 3, a kind of change stroke mechanical hand clamping jaw structure, including
Wide type pneumatic clamper 1 and two clamping parts 2 being oppositely arranged, wide type pneumatic clamper 1 include the first cylinder 11 and two positioned opposite and energy edges
The corpus unguis 12 of opposite direction linear movement, the center line being connected between corpus unguis 12 and clamping part 2 along wide type pneumatic clamper 1 are arranged symmetrically
And the second cylinder 3 for adjusting 2 stroke of clamping part, wherein the second cylinder 3 adjusts direction and the corpus unguis 12 of 2 stroke of clamping part
Moving direction it is parallel.It is the utility model stable structure, easy to use, by adjusting the stroke of both sides clamping jaw simultaneously, it is used for
The gripping for adapting to different sized products haves no need to change the position of center line that adjustment clamping jaw is also needed to after stroke, improves work effect
Rate.
In the present embodiment, the buffering of clamping part 2 and workpiece collision can be slowed down by being equipped between clamping part 2 and the second cylinder 3
Device 4.Buffer unit 4 includes the bearing 41 being fixedly connected with the second cylinder 3, is arranged with and opposite with bearing 41 can move on bearing 41
The moving direction of dynamic guide rod 42, the moving direction and corpus unguis 12 of guide rod 42 is perpendicular, and guide rod 42 is fixed with clamping part 2
Connection, is additionally provided with the spring 43 being socketed with guide rod 42 between bearing 41 and clamping part 2.
Here, guide rod 42 could be provided as the shape of cuboid, the effect of limit can be directly reached in this way.In this practicality
In novel, in order to keep limit more stable and accurate, using cylindrical guide rod 42, meanwhile, buffer unit 4 includes that can guide
The line rail 44 that clamping part 2 moves along a straight line, line rail 44 and guide rod 42 are respectively arranged on the both sides of clamping part 2, line rail 44 and branch
Seat 41 is fixedly connected.2 energy of clamping part under the position-limiting action of rail 4, has the opposite sliding of short distance, to facilitate folder in vertical direction online
Contact of the portion 2 in gripping with workpiece is held, but the movement of clamping part 2 is easy to damage the second cylinder 3 of upper end, especially
Using the second cylinder 3 of light and thin type, therefore, the spring 41 of buffer unit 4 can preferably slow down the collision suffered by the second cylinder 3,
Extend the service life of the second cylinder 3.
In the present embodiment, wide type pneumatic clamper 1 further includes being set to the mounting portion 13 of 11 top of the first cylinder.Mounting portion 13 is used for
The installation of entire clip claw mechanism and manipulator connects.Second cylinder 3 is slim guide rail cylinder.Slim guide rail cylinder is lighter,
The load for mitigating wide type pneumatic clamper 1 makes whole device structure more stablize.Two opposite sides of clamping part 2 are equipped with clamping jaw piece
