1. a kind of opening-and-closing chuck, which is characterized in thatLinear guide rail is set on the outside of chuck main body, a pair of of manipulator of clamping workpiece is arranged on the guideway, it shouldAt least one is the moving machinery hand moved freely along the guide rail among a pair of of manipulator,The track embeded slot that there is the moving machinery hand guide rail to be fitted into, the side wall inner surface in the left and right of the track embeded slotThe first groove and the track of the rail-sides are respectively formed with the position opposite each other of the side of the left and right of the guide railSecond groove of embeded slot side, the sandwiched rolling element between first groove and the second groove pass through the rolling of the rolling element, instituteMoving machinery hand is stated to move freely along the guide rail,In the inside of the chuck main body, setting is with the moving machinery palmistry with the air cylinder device of quantity, air cylinder device toolThe standby piston and bar that moving back and forth is carried out by the axis direction for acting on cylinder-bore of air pressure, the front end of the bar is from instituteThe end for stating chuck main body is protruding to the outside, in the front end of the bar, to pass through the moving back and forth of the bar and the chuck main bodyEnd it is close and isolated mode installs the end block opposite with the end of the chuck main body,The end block is that side observation shape in the case where axis direction observation forms substantially rectangular end block, with eachFrom inner side end and the chuck main body the first end side and opposite mode configures in parallel the end face of the second end side,On the inner side end of the end block, it is mounted with flexible end damper,The moving machinery hand and the end block link, and driving is opened and closed through the end block by the bar,The end of side among the length direction both ends of the guide rail provided with the end block is from the end of the chuck main bodyIt is prominent into the movable area of the end block, on the end block, in order to avoid the collision with the guide rail, form the guide railOne end insertion avoid holes,The position of the bar and end block connection is proximate to the position of the one end of a long side of the rectangle of the end blockIt sets, and is proximate to the position of the one end of a short side of the rectangle of the end block;

  • The moving machinery hand with it is describedThe position of end block connection is proximate to the position of the one end of another long side of the rectangle of the end block, and is proximate to instituteState the position of the one end of another short side of the rectangle of end block.
