[0033] The base plate 1 is hinged with a swing arm 5, the swing arm 5 is provided with a pressing plate 6, and the swing arm 5 can drive the pressing plate 6 to press onto the clamping seat 4.

[0034] In the embodiment, the workpiece is a slot pipe 7, and the slot pipe 7 includes a slot plate 701 and a cover plate 702, and the cover plate 702 can be buckled onto the slot plate 701, and the two can be welded together to form the slot pipe 7.

[0035] Specifically, the clamping seat 4 includes a fixed table 401, a guide rail 403, and a hinged seat 405 provided on the base plate 1.

[0036] The clamping block 404 is movably arranged on the guide rail 403; in the embodiment, the clamping block 404 is slidingly connected to the guide rail 403, as Figure 1 shown.

[0037] The hinged seat 405 is provided with a clamping roller 402, which is arranged between the fixed table 401 and the clamping block 404.

[0038] The clamping roller 402 has a clamping gap with the fixed table 401, the guide rail 403, and the clamping block 404, and the workpiece can be inserted into the clamping gap. In the embodiment, when the slot pipe 7 is welded and positioned, the slot plate 701 can be inserted into the clamping gap, the cover plate 702 is buckled onto the slot plate 701 and is pressed tightly by the pressing plate 6, as Figure 2 and Figure 3 shown; further, after positioning is completed, the slot plate 701 and the cover plate 702 can be welded and combined by manual operation. In the embodiment, the minimum value of the clamping gap between the clamping roller 402 and the fixed table 401 is equal to the wall thickness of the slot plate 701.

[0039] As Figure 2In the embodiment, the number of the hinge seats 405 is 2, and the number of the clamping rollers 402 is also 2. The two clamping rollers 402 are respectively close to the inner side of the fixed table 401 and the clamping block 404, as shown in the figure. Figure 3 As shown in the figure.

[0040] The base plate 1 is also provided with a stop block 406 for limiting the workpiece. The stop block 406 is arranged between the fixed table 401 and the clamping block 404. The stop block 406 can be used for axial limiting of the groove pipe 7.

[0041] Specifically, the clamping wheel assembly 2 includes an eccentric wheel frame 201 arranged on the base plate 1, an eccentric wheel 202 hinged to the eccentric wheel frame 201, and a handle 203 arranged on the eccentric wheel 202.

[0042] One end of the jacking rod 301 is hinged to the clamping block 404. The other end of the jacking rod 301 can abut against the eccentric wheel 202. Rotating the handle 203 can drive the eccentric wheel 202 to rotate, and the eccentric wheel 202 can drive the clamping block 404 to move along the guide rail 403 through the jacking rod 301.

[0043] In the embodiment, when the side with larger radius of the eccentric wheel 202 abuts against the jacking rod 301, the clamping block 404 moves to the side close to the fixed table 401, and the groove pipe 7 can be clamped; on the contrary, when the side with smaller radius of the eccentric wheel 202 abuts against the jacking rod 301, the clamping block 404 moves to the side away from the fixed table 401, and the groove pipe 7 loses clamping.

[0044] In the embodiment, the eccentric wheel 202 and the jacking rod 301 can realize self-locking, and the jacking rod 301 cannot reversely push the eccentric wheel 202. Artificially rotating the eccentric wheel 202 can adjust the clamping gap between the clamping block 404 and the clamping roller 402. The clamping gap between the clamping block 404 and the clamping roller 402 is constant during conventional welding. When the groove pipe 7 is clamped between the fixed table 401 and the clamping block 404 due to thermal deformation after welding, the eccentric wheel 202 can be manually rotated to move the clamping block 404 away from the clamping roller 402, so as to increase the clamping gap between the clamping block 404 and the clamping roller 402, thereby facilitating the removal of the groove pipe 7 from the clamping seat 4. Next time, the clamping block 404 can be adjusted to the original position to clamp and position the groove pipe 7 again.

[0045] Specifically, the jacking rod assembly 3 includes a support seat 302 arranged on the base plate 1, a jacking rod 301 slidingly connected to the support seat 302, a stop table 3011 arranged at one end of the jacking rod 301, and a spring 303 sleeved on the jacking rod 301, which can be elastically supported between the stop table 3011 and the support seat 302, as shown in the figure. Figure 5 The spring 303 can be used for elastic return of the jacking rod 301, so that the jacking rod 301 can continuously contact the eccentric wheel 202.

[0046] In the embodiment, the stop table 3011 is fixedly connected to the top rod 301 by a screw at an end away from the clamping block 404.

[0047] One end of the top rod 301 is hingedly connected to the clamping block 404; the stop table 3011 can abut against the eccentric wheel 202, as shown in Figure 5 .

[0048] Specifically, the clamping roller 402 comprises a roller body 4021, a flat surface 4022 is arranged on the side wall of the roller body 4021, and a lever 4023 is arranged on the roller body 4021. In the embodiment, the cross section of the clamping roller 402 is in the shape of D; the clamping roller 402 can be rotated by the lever 4023 by manual operation; when the flat surface 4022 faces the inner side of the fixed table 401 and the clamping block 404, the clamping gap between the clamping roller 402 and the two is increased; at this time, the groove plate 701 can be loosely inserted into the clamping gap; after the groove plate 701 is inserted, the clamping roller 402 is rotated until the outer circular surface of the roller body 4021 abuts against the inner side of the groove plate 701; at this time, the groove plate 701 is clamped between the clamping roller 402, the fixed table 401 and the clamping block 404.

[0049] Specifically, as shown in Figure 2 , a handle is arranged on the swing arm 5 to facilitate manual gripping of the swing arm 5.

[0050] The specific use principle of the utility model is as follows:

[0051] First, the clamping roller 402 is rotated by the lever 4023 by manual operation, so that the flat surface 4022 of the clamping roller 402 faces the inner side of the fixed table 401 and the clamping block 404; at this time, the clamping gap between the clamping roller 402 and the two is increased, so that the groove plate 701 can be loosely inserted into the clamping gap. One end of the groove plate 701 can be axially limited against the stop block 406 to ensure accurate positioning.

[0052] After the groove plate 701 is inserted in place, the clamping roller 402 is rotated again, so that the outer circular surface of the roller body 4021 abuts against the inner side of the groove plate 701, thereby clamping the groove plate 701 between the clamping roller 402, the fixed table 401 and the clamping block 404. Then, the cover plate 702 is buckled to the groove plate 701, and then the swing arm 5 is driven by manual operation to press the pressing plate 6 to one side of the clamping seat 4, so that the pressing plate 6 presses and positions the cover plate 702 to the groove plate 701, completing the positioning before welding of each component of the groove pipe 7; at this time, the groove plate 701 and the cover plate 702 can be manually welded.

[0053] After the welding is completed, if the groove pipe 7 is clamped due to thermal deformation, the eccentric wheel 202 can be driven to rotate by the crank 203, at this time the top rod 301 moves under the support of the spring 303, the top rod 301 drives the clamping block 404 to move away from the clamping roller 402 along the guide rail 403, so as to increase the clamping gap, and the welded groove pipe 7 is conveniently taken off from the clamping seat 4. After the groove pipe 7 is taken off, the eccentric wheel 202 is manually rotated to drive the clamping block 404 to reset through the top rod 301, so as to prepare for the next clamping.
