The two clamping brackets are completely identical in structure and are arranged relative to each other, and the distance between the two clamping brackets is adjustable. The two clamping springs are completely identical in structure and are arranged relative to each other, and the clamping springs can be adjusted forward and backward.

[0006] The clamping bracket includes a horizontal fixing part, an inclined part and a clamping part. The horizontal fixing part is fixedly connected to the handle, the inclined part is inclined in a direction away from the handle, and the clamping part is parallel to the handle and extends toward the front of the handle.

[0007] The rear end of the clamping spring piece is fixedly connected to the handle, and the front end is semicircular. The front ends of the two clamping spring pieces are arranged opposite to each other.

[0008] The adjusting block is fixedly connected to the adjusting block fixing plate by bolts, and a gasket is arranged between the adjusting block fixing plate and the adjusting block.

[0009] A mounting hole is provided on the clamping spring piece, and long strip bolt holes are provided on the upper and lower sides of the handle respectively, and the clamping spring piece is fixedly connected to the handle by bolts.

[0010] The advantages of the utility model are as follows: the utility model first clamps the small-volume workpiece by the clamping spring sheet, and then puts the tool with the small-volume workpiece into the large-volume workpiece through the handle, and the clamping bracket clamps the outer end of the large-volume workpiece, and completes the pre-positioning while ensuring that the relative positions of the two workpieces meet the requirements, and completes the subsequent clamping operation of the fixture. At this time, the large-volume workpiece has been completely positioned and clamped by the fixture, and finally the tool is removed for welding. The utility model has a reasonable design, simple operation, and low manufacturing cost. When the worker operates, the tool can be used to easily clamp the workpiece in place, saving time and effort.

[0014] like Figure 1 As shown, a workpiece auxiliary clamping tool for a small space includes a handle 1, a clamping bracket 2 is fixed on the upper and lower sides of the middle part of the handle 1, a clamping spring 4 is fixed on the upper and lower sides of the handle 1 in front of the clamping bracket 2, an adjustment block fixing plate 6 is fixed between the two clamping springs 4 at the front of the handle 1, and an adjustment block 3 is fixedly installed on both ends of the adjustment block fixing plate 6 on both sides of the handle 1. The two clamping brackets 2 have the same structure and are arranged relative to each other. The distance between the two clamping brackets 2 can be adjusted. By arranging gaskets of different thicknesses between the clamping brackets 2 and the handle 1, the distance between the two clamping brackets can be adjusted to adapt to large-volume workpieces 5 of different widths; the two clamping springs 4 have the same structure and are arranged relative to each other. The clamping springs 4 can be adjusted forward and backward to adapt to the size of large and small volume workpieces. The adjustment block 3 can be adjusted forward and backward according to the relative position between the large and small volume workpieces. Similarly, the front and rear position of the adjustment block can be adjusted by adjusting the thickness of the gasket between the adjustment block 4 and the adjustment block fixing plate 6. The clamping spring 4 can clamp small-volume workpieces 7 within a certain range.

[0015] The clamping bracket 2 includes a horizontal fixed part, an inclined part and a clamping part. The horizontal fixed part is fixedly connected to the handle, the inclined part is inclined in the direction away from the handle, and the clamping part is parallel to the handle and extends toward the front of the handle. When in use, the clamping part is clamped on the outside of the large workpiece 5.

[0016] The rear end of the clamping spring piece 4 is fixedly connected to the handle 1 , and the front end is semicircular, and the front ends of the two clamping spring pieces are arranged opposite to each other. When in use, the small-volume workpiece 7 is clamped between the front end arcs of the two clamping spring pieces 4 .

[0017] The adjusting block 3 is fixedly connected to the adjusting block fixing plate 6 by bolts, and a gasket is provided between the adjusting block fixing plate 6 and the adjusting block 3. The front and rear positions of the adjusting block can be adjusted by adjusting the thickness of the gasket between the adjusting block 3 and the adjusting block fixing plate 6.

[0018] A mounting hole is provided on the clamping spring piece 4, and long strip bolt holes are provided on the upper and lower sides of the handle 1, respectively, and the clamping spring piece 4 is fixedly connected to the handle 1 by bolts. The position of the clamping spring piece 4 can be adjusted forward and backward.

[0019] like Figure 2 , 3 As shown, the small-volume workpiece 7 is clamped by the clamping spring 4, and then the tool with the small-volume workpiece 7 is placed in the large-volume workpiece 5, the clamping bracket 2 clamps the outer end of the large-volume workpiece 5, and the adjustment block 3 blocks the outer end of the large-volume workpiece 5. The pre-positioning is completed while ensuring that the relative positions of the two workpieces meet the requirements, and the subsequent clamping operation is completed by the welding fixture 8. After the clamping is completed, the tool of the utility model is removed and the welding operation is performed. Since the clamping spring 4 is elastic, it is easy to remove the tool of the utility model. The welding fixture 8 used here does not belong to the protection scope of the utility model. The utility model only protects the clamping tool. The welding fixture is selected according to the different workpieces.
