[0027] When the utility model is used, the locking screw 104 is gradually unscrewed from the threaded hole of the sliding plate 103, when the locking screw 104 is no longer in contact with the workbench 101, the fixing state of the sliding plate 103 on the workbench 101 is released, then the fixed nut 112 is gradually unscrewed from the fixed bolt 111, when the fixed nut 112 is completely unscrewed from the fixed bolt 111, the fixed bolt 111 is removed from the through hole of the rotating rod 109 and the fixed plate 110, so that the fixing state of the rotating rod 109 is released, repeat the above operation, the fixing state of all the sliding plate 103 and the rotating rod 109 is released, after the fixing state is released, the two sliding plates 103 arranged oppositely move away from each other until the distance between the two sliding plates 103 arranged oppositely reaches the maximum.

[0028] At this time, the workpiece to be clamped and positioned is placed on the supporting block 102, the sliding plate 103 is moved towards the workpiece, thereby driving the rotating block 105 to move towards the workpiece, and further driving the clamping plate 106 to move towards the workpiece, in the process of moving the clamping plate 106 towards the workpiece, the rotating block 105 is rotated, thereby driving the clamping plate 106 to rotate, combined with the movement of the clamping plate 106 towards the workpiece, the clamping plate 106 can be rotated to a position matched with the shape of the workpiece and clamps the workpiece, at this time, the telescopic rod 113 and the buffer spring 114 can jointly buffer the clamping plate 106, so that the workpiece is clamped more accurately and the error is reduced, in the process of rotating the clamping block, the rotating rod 109 rotates with the rotating block 105, thereby driving the second gear 108 to rotate along its axis in the first gear 107, and further driving the first gear 107 to rotate along its axis in the groove 115, through the rotation of the first gear 107 along its axis in the groove 115, the position of the rotating block 105 is temporarily limited.

When the locking screw 104 presses the workbench 101 tightly, the locking screw 104 can no longer be screwed in. At this time, the locking screw 104 fixes the slide plate 103 on the workbench 101, so that the clamping plate 106 can no longer move. Finally, the fixing bolt 111 is inserted into the through holes of the rotating rod 109 and the fixing plate 110 in sequence, and The fixing nut 112 is gradually screwed into the outside of the fixing bolt 111. When the end of the fixing bolt 111 contacts the rotating rod 109 and the fixing nut 112 contacts the fixing plate 110, the fixing nut 112 is tightened outside the fixing bolt 111, so that the rotation position of the rotating rod 109 is limited and fixed, and the rotation position of the clamping plate 106 is limited and fixed and cannot continue to rotate. Since the clamping plate 106 can no longer move and rotate, the clamping plate 106 can clamp and position the workpiece. Repeat the above operation, so that the clamping plate 106 can clamp and position irregularly shaped workpieces, thereby improving the applicability of the positioning auxiliary device.
