In the process that the clamping block 22 clamps the workpiece therein, the shape of the workpiece needs to be adjusted, if only direct clamping is adopted, no external interference is added, and the aim of adjustment is possible to be achieved, the invention adopts the adjusting part 23 arranged on the sliding part 21, the rotating chuck 230 is controlled by the locking unit 24, the rotating chuck 230 can act on one clamping block 22 or two clamping blocks according to the requirement, the rotating chuck 230 rotates, the front end of the rotating chuck 230 is contacted with the inner side of the clamping block 22, the rotating chuck 230 rotates to move the clamping block 22 in the sliding part 21 towards two outer sides, so that the two clamping blocks 22 can not act on the workpiece at the same time, the force form applied to the two sides of the workpiece is not a couple, the workpiece can be self-adjusted, but the last two clamping blocks 22 can act on the two sides of the workpiece for clamping, and the aim of adjusting the workpiece is achieved, meanwhile, the position of the workpiece is limited, and the six-axis mechanical arm 1 can be grabbed conveniently.

The supporting component 3 is arranged between the two sliding portions 21, the supporting component 3 comprises a telescopic cylinder (not shown in the figure) and a supporting block 32, the telescopic cylinder is connected to the bottom of the processing platform 14, the head of the telescopic cylinder is connected with a detachable ejector rod 33, the supporting block 32 is connected with the telescopic cylinder through the ejector rod 33, the telescopic cylinder controls the supporting block 32 to ascend and descend and contacts with the bottom of the workpiece 7, and then the pressure of the workpiece 7 on the clamping blocks 22 on the two sides is adjusted.

Set up supporting component 3 between two sliding parts 21, increase the adjustment of a vertical direction to the work piece position on the one hand, can further avoid the emergence of work piece skew, on the other hand, telescopic cylinder control supporting shoe 32 rise with descend and contact with the bottom of work piece, it is too big to receive two grip block 22 form squints when the work piece, the contained angle that forms with the surface of water is big, make grip block 22's impetus undersize, make the centre gripping dynamics when too big, through the removal from top to bottom with the work piece, change work piece outer wall and grip block 22's contact impetus, adjust the work piece to the pressure of both sides grip block 22, and then make the centre gripping more balanced.

The outside of supporting component 3 is connected with the strengthening rib, and telescopic cylinder passes through the strengthening rib to be connected with processing platform 14. The reinforcing ribs play a role in reinforcing the connection between the fixed support assembly 3 and the processing platform 14. The leveling component 4 is arranged on one side of the limiting component 2, a through hole 41 is formed in the leveling component 4, and an elastic rubber pad 42 is arranged on the inner wall of the through hole 41. The flat-arranging component 4 is added, the other side of the tubular workpiece is sleeved in the through hole 41 to support and lift the tubular workpiece to keep horizontal, wherein the elastic rubber pad 42 is used for placing the workpiece to be in direct contact with the through hole 41 to collide with the inner wall of the through hole 41 to damage or wear after long-time work, the flat-arranging component 4 is provided with a slide rail 43, and the flat-arranging component 4 is in sliding connection with the processing platform 14 through the slide rail 43. The flat-arranging component 4 is provided with a slide rail 43, the force point of the through hole 41 on the flat-arranging component 4 and the tubular workpiece is changed through the slide rail 43, the flat-arranging component can adapt to the requirements of tubular workpieces with different lengths, the adjustment is convenient, the inner sides of the clamping blocks 22 are arc-shaped, and a gap is reserved between the two clamping blocks 22. The clearance is to leave a space for the ejector rod 33 and the head of the telescopic cylinder. The inner side of the clamping block 22 is arc-shaped, which can be customized according to the outer shape of the actual workpiece, and is also suitable for the requirement of tubular workpieces.
