Referring to fig. 1 to 6, the self-locking clamping device for welding the header 5, which is suitable for multiple specifications, includes a support 1, two guide shafts 3, a flexible clamping module 4, and further includes a V-shaped support block 2:
the two guide shafts 3 are horizontally and fixedly arranged on the support 1 in parallel, the flexible clamping module 4 is provided with a through hole matched with the guide shafts 3, and the flexible clamping module 4 is slidably arranged on the guide shafts 3 through the through hole;
the V-shaped supporting block 2 is in a strip shape, and the V-shaped supporting block 2 is arranged on the support 1;
the flexible clamping module 4 comprises a support 41, a lifting mechanism, a pressing mechanism and a driving cylinder 44, wherein the through hole is formed in the support 41, a shell part of the driving cylinder 44 is fixedly arranged on the support 41, a wedge block 45 is arranged at the output end of the driving cylinder 44, a plurality of inclined plane groups are arranged on a slope surface 451 of the wedge block 45, and each inclined plane group comprises a lifting inclined plane 4511 and a balance inclined plane 4512 which are connected;
it includes slider 421, locates the gas spring 422 of slider 421 top and locates the platform 424 that lifts above the gas spring 422 to lift the mechanism, it is located to lift the platform 424 the below of V type tray 2, the lower surface and the wedge 45 looks adaptation of slider 421. The included angle between the balance inclined surface 4512 and the horizontal plane is smaller than the equivalent friction angle between the balance inclined surface 4512 and the slider 421.
The pressing mechanism is two sets of link mechanisms symmetrically arranged, each link mechanism comprises a connecting rod 431, a pressing arm 432 and a pressing block 433, the middle of each pressing arm 432 is arranged on the support 41 through a pin shaft 435, the lower end of each connecting rod 431 is hinged to the corresponding sliding block 421, the upper end of each connecting rod 431 is hinged to the lower end of each pressing arm 432, and the pressing blocks 433 are arranged at the upper ends of the pressing arms 432. The pressing mechanism is driven by the slide block 421 to realize synchronous clamping movement of the header 5.
The bracket 41 comprises a first side plate and a second side plate which are arranged in parallel, and the lifting mechanism and the pressing mechanism are arranged between the first side plate and the second side plate. Because the sliding block 421 is limited between the first side plate and the second side plate, it cannot move along the horizontal direction, and a guide groove in the vertical direction is arranged on the inner side of the first side plate and the second side plate, so that the sliding block 421 moves in the guide groove, and further, the sliding block 421 can only move in the vertical direction.
When the driving cylinder 44 pushes the wedge-shaped block 45 to move in the horizontal direction, the lifting surface on the slope surface 451 of the wedge-shaped block 45 is inserted below the slider 421 to force the slider 421 to move in the vertical direction, so that the lifting platform 424 abuts against the bottom of the V-shaped supporting block 2, when the balance inclined surface 4512 on the slope surface 451 of the wedge-shaped block 45 reaches below the slider 421, if the action of the driving cylinder 44 is stopped, because the included angle between the balance inclined surface 4512 and the horizontal plane is smaller than the equivalent friction angle between the balance inclined surface 4512 and the slider 421, friction self-locking can be generated on the movement of the slider 421 in the vertical direction;

If the V-shaped support block 2 is not provided, the welding deformation force is transmitted to the guide shaft 3, which causes the deflection deformation of the guide shaft 3, and if the guide shaft 3 is deformed, the clamp to the header 5 is deformed, and the welding deformation of the header 5 cannot be suppressed.
The flexible clamping module 4 is designed to drive the air cylinder 44 to push the wedge-shaped block 45, the inclined plane of the wedge-shaped block 45 is designed according to an equivalent friction angle, the wedge-shaped block 45 is matched with the sliding block 421 to realize the upward movement of the sliding block 421, and meanwhile, mechanical friction self-locking is formed at the clamping position, so that the welding deformation of the headers 5 with different specifications is overcome; the driving cylinder 44 drives the connecting rod 431 and the pressing arm 432 which are symmetrically arranged to enable the pressing blocks at the two sides to synchronously clamp the manifold 5, so that the manifold 5 is prevented from being pressed and biased to influence the positioning. After welding, the driving cylinder 44 pulls the wedge block 45 to retract, and the gas spring 422 pushes the sliding block 421 to move downwards, so that the clamping device is reset.
The device realizes symmetrical clamping, automatic clamping and opening and friction mechanical self-locking, realizes automatic positioning of the collecting pipe 5, overcomes welding deformation, ensures stable welding seams and improves the forming size of a product after welding.
One end of the gas spring 422 is screwed on the slide block 421, and the other end is provided with a bulb 423 and is arranged in the storage groove of the flexible clamping module 4.
The gas spring 422 utilizes the ball head 423 to realize flexible connection, the acting force of the ball head 423 in the storage groove is parallel to the axial direction of the gas spring 422, and the resetting fluency and the service life of the gas spring 422 are improved.
The flexible clamping module 4 can move on the guide shaft 3, so that the positioning requirements of the headers 5 with different lengths are met; the V-shaped supporting block 2 can be adapted to the collecting pipes 5 with different diameters by virtue of the V-shaped structure, and automatic centering and positioning can be realized, so that the device can be adapted to positioning and clamping of the collecting pipes 5 with different lengths and different diameters. According to the scheme, the four-point compression of the collecting pipe 5 is realized by means of the compression mechanism and the V-shaped supporting block 2, and meanwhile, mechanical friction self-locking is formed at a clamping position, so that the collecting pipe 5 is firmly maintained in an original state; the symmetrically arranged link mechanisms are driven to enable the pressing blocks 433 on the two sides to synchronously clamp the manifold 5, so that the manifold 5 is prevented from being biased to influence positioning.
