[0019] Specifically, the replacement unit 3 comprises a connecting frame 31, a clamping head 32, a connecting seat 33, a mounting box 34, a threaded cylinder 35, a screw rod 36, two slide rails 37, a moving plate 38, a bearing seat 39 and an insertion block 310, the connecting frame 31 is fixedly arranged at the top of the adjusting seat 22, the connecting seat 33 is fixedly connected with the clamping head 32, and the connecting seat 33 is movably arranged in the connecting frame 31, the connecting seat 33 can move freely in the connecting frame 31, a clamping groove is arranged at the top of the connecting seat 33, the mounting box 34 is fixedly arranged at the outer top of the connecting frame 31, the threaded cylinder 35 is fixedly arranged at the outer top of the mounting box 34, the screw rod 36 is threadedly connected with the threaded cylinder 35, the screw rod 36 movably penetrates through the top of the mounting box 34, the two slide rails 37 are respectively fixedly arranged at the left and right sides in the mounting box 34, the moving plate 38 is slidably connected with the two slide rails 37, and the top of the moving plate 38 is connected with the bottom end of the screw rod 36 through the bearing seat 39, and the insertion block 310 is fixedly arranged at the bottom of the moving plate 38 and movably penetrates through the top of the connecting frame 31, and the insertion block 310 is matched with the clamping groove.
[0020] Specifically, the top end of the screw rod 36 is fixedly provided with a handle 311, which facilitates the rotation of the screw rod 36.
[0021] Working principle: when fixing metal products, the operation process starts from selecting a suitable clamping head 32, which ensures that the device can adapt to different shapes of workpieces. The selected clamping head 32 is provided with a connecting seat 33, which is inserted into the connecting frame 31 to lay the foundation for the fixation of the clamping head 32. Then, the operator starts to rotate the screw rod 36 downward, which converts the rotary motion of the moving plate 38 into linear motion through the limiting action of the bearing seat 39 and the slide rail 37. With the downward movement of the moving plate 38, the insertion block 310 fixed at the bottom of the moving plate 38 also moves downward and finally accurately inserts into the clamping groove of the connecting seat 33, so that the clamping head 32 is firmly fixed in the appropriate position.
[0022] After the fixation of the clamping head 32 is completed, the next step is to adjust the height of the replacement unit 3 to adapt to the different height requirements of the workpiece. This process is completed by moving the adjusting seat 22 up and down, and the operator moves the adjusting seat 22 to the appropriate height to ensure that the adjusting hole on the adjusting seat 22 corresponds to the pair of fixed holes on the supporting seat 21. Once the position is aligned, the operator passes the bolt 23 through the adjusting hole and the fixed hole of the supporting seat 21, and tightens the bolt 23 with the nut 24, thereby completing the height adjustment.
[0023] Finally, the staff can perform positioning operation.
