[0025] A fixed rod 16 is fixedly connected in the installation cavity, and the moving block 12 is slidably connected to the fixed rod 16. A second spring 17 is sleeved on the fixed rod 16, one end of the second spring 17 is fixedly connected to the fixed rod 16, and the other end of the second spring 17 is fixedly connected to the moving block 12. The limit block 13 is in contact with the lower surface of the moving block 12 in the initial state. When the slide plate 14 shrinks into the installation cavity, the limit block 13 will be offset from the moving block 12. Under the elastic force of the second spring 17, the moving block 12 will move downward, and after the pressure plate 7 moves downward, the lower surface of the rubber material will be in close contact with the upper surface of the workpiece.

[0026] A plurality of slots are provided on one side of the second clamping plate 6, in which an insertion rod 15 is clamped, and a round hole for connecting the insertion rod 15 is provided on the moving block 12. One end of the insertion rod 15 is passed through the round hole and clamped with the corresponding slot on the second clamping plate 6, which can prevent the moving block 12 from sliding relative to the second clamping plate 6 at will. A limiting plate 2 is fixedly connected to the support seat 1, and a plurality of through holes are provided on the limiting plate 2. A groove is provided on one side of the support plate 5, and the limiting plate 2 is connected to the groove through an insertion shaft. One end of the insertion shaft is passed through the corresponding through hole on the limiting plate 2 and clamped with the groove, which can prevent the support plate 5 and the slider 11 from rotating relative to each other.

[0027] A rectangular groove for installing a slider 11 is provided on the support seat 1, and a reciprocating screw 10 is rotatably arranged in the rectangular groove. The slider 11 is threadedly connected to the reciprocating screw 10, and the reciprocating screw 10 is manually rotated. During the rotation of the reciprocating screw 10, the slider 11 will move along the reciprocating screw 10, and the slider 11 can slide stably horizontally inside the slide groove, so that the position of the support plate 5 and the workpiece can be adjusted.

[0029] In the present invention, when in use, the workpiece is first placed on the support plate 5, and one side surface of the workpiece is made to fit with the surface of the first clamping plate 8, and then the hydraulic cylinder 3 works, the hydraulic cylinder 3 drives the bending block 4 to move, and then drives the second clamping plate 6 to move in the direction close to the first clamping plate 8, and during the movement of the slide plate 14, one side surface of the slide plate 14 will move against the surface of the workpiece, and the slide plate 14 will slide relative to the second clamping plate 6 at the same time, until the one side surface of the slide plate 14 and the surface of the second clamping plate 6 are in the same plane, and the surfaces of the slide plate 14 and the first clamping plate 8 are both in contact with the surface of the workpiece. Tightly fitting, at this time, the compression of the first spring 18 reaches the maximum, and the limit block 13 is in contact with the lower surface of the moving block 12 in the initial state. During the process of the slide plate 14 shrinking to the inside of the installation cavity, the limit block 13 will be staggered with the moving block 12, and under the elastic force of the second spring 17, the moving block 12 will move downward, and after the pressure plate 7 moves downward, the lower surface of the rubber material will be in close contact with the upper surface of the workpiece. Under the joint limiting action of the first clamping plate 8, the second clamping plate 6, the slide plate 14 and the pressure plate 7, the workpiece can be limited and fixed, and the operation is relatively convenient and quick, which is conducive to the use of the welding platform.
