Detailed ways

Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be combined arbitrarily to form new implementations. example.

As shown in Figure 1-2, the welding flexible tooling includes a workbench 1, a pair of lateral support rods 2 are symmetrically arranged on both sides of the workbench 1, and a clamping device is provided on the support rods 2.

The clamping device includes a sliding rod 31, an upper pressing plate 32 and a lower pressing plate 33. The upper pressing plate 32 is movably connected to the upper part of the sliding rod 31 and moves up and down along the axial direction of the sliding rod 31. The lower pressing plate 33 is fixedly arranged. At the bottom of the sliding rod 31, the sliding rod 31 is fixedly connected with the support rod 2, the sliding rod 31 is provided with an external thread, and a nut 34 is sleeved on the sliding rod 31, and the nut 34 is located at the bottom of the sliding rod 31. above the upper platen 32;

The bottom of the upper pressing plate 32 and the top of the lower pressing plate 33 are both provided with an accommodating groove 35, a pair of notches of the accommodating grooves 35 are opposite to each other, and a baffle plate 36 is arranged in the accommodating groove 35, The baffle plate 36 is provided with a plurality of through holes, and a clamping rod 37 is passed through the plurality of the through holes. A spring 38. A pair of clamping devices respectively clamps a piece to be welded, and the position of the clamping device can be adjusted by sliding the sliding plate 12; when using the clamping device to clamp, rotate the nut 34 upward, and then manually move the upper pressure plate 32 upward to increase the The distance between the upper pressure plate 32 and the lower pressure plate 33, the part to be clamped is placed between the upper pressure plate 32 and the lower pressure plate 33, and the nut 34 is rotated downward to drive the upper pressure plate 32 to move downward, reducing the gap between the upper pressure plate 32 and the lower pressure plate 33. The distance between the clamping rod 37 and the workpiece to be welded is in contact. When the distance is gradually reduced, the clamping rod 37 is squeezed to move toward the bottom of the accommodating groove 35, and the first spring 38 is in a compressed state. The shape and the moving distance of the clamping rods 37 are inconsistent, and finally the curved surfaces where the clamping rods 37 are located are consistent with the surface of the workpiece to be welded, which maximizes the contact area between the clamping device and the workpiece to be welded and ensures the clamping effect. It is stable and reliable, and at the same time, under the elastic support of the first spring 38, the contact with the piece to be welded is more flexible and elastic, and the structure is reasonable and compact, which improves the versatility of the clamping device.
