[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a pipe head welding auxiliary device. The pipe head welding auxiliary device includes a base assembly 1, a clamping assembly 2, and a clamping component 3. By cooperating with the clamping assembly 2 and the clamping component 3, the limitations of traditional fixed brackets are broken, and the position of the clamping component can be adjusted to meet the precise positioning requirements of welding at different angles. The eccentric shaft hole of the clamping assembly 2 is linked with the extrusion column, which can realize the quick locking and releasing of the clamping component through simple operation, greatly shortening the braking time and significantly improving the work efficiency.

[0035] Specifically, the base assembly 1 includes a base 11, the top of which has a first movable groove 11-1 and the center of the top of the base 11 has a second movable groove 11-2, and the bottom of the inner cavity of the first movable groove 11-1 and the second movable groove 11-2 are both fixed with toothed plates 12.

[0036] By using the first movable groove 11-1 of the circumferential array, the clamping component 3 can be installed in the first movable groove 11-1 at different positions to meet the welding requirements of pipe heads at different angles. In conjunction with the second movable groove 11-2, multi-angle pipe head welding can be achieved.

[0037] Specifically, the clamping component 2 is disposed on the base 11, including a support seat 21 fixed to the top of the base 11, a support block 22 fixed on the support seat 21, a fixing rod 23 connected to the inner side of the support block 22, a handle 25 rotatably connected to the fixing rod 23, a pressing column 24 slidably connected inside the support seat 21, and a first spring 27 disposed on the outer side of the pressing column 24.

[0038] By setting the clamping component 2, the extrusion column 24 can apply anti-slip pressure to the clamping component 3 after the clamping component 3 has completed its operation, effectively ensuring the stability of the position of the clamping component 3, which is more in line with the requirements of subsequent welding processing.

[0039] Specifically, the clamping member 3 is disposed on the top of the base 11, including a clamp housing 31 located on the top of the base 11. The clamp housing 31 has a first storage groove 31-1 on both sides. The first storage groove 31-1 is rotatably connected to the clamping arm 35. The clamping arm 35 can expand outward or retract inward along the first storage groove 31-1.

[0040] A gear 32 is provided inside the clamp housing 31. A fixed shaft 32-1 is fixed at the center of the gear 32. The fixed shaft 32-1 is rotatably connected to the clamp housing 31. A clamping arm 35 is fixed on the outer ring of the fixed shaft 32-1. A second spring 33 is fixed on the inner side of the clamping arm 35. A clamping claw 36 is fixed on the top of the clamping arm 35.

[0041] Using the reset force of the second spring 33, the gripper 36 is made to fit against the curved surface of the pipe head wall to pre-clamp and position the pipe. Through the cooperation of the gear 32 and the toothed plate 12, the gripper slides up and down on the clamp housing 31, which can open or close the clamping arm 35 connected to the gear 32 along the first receiving groove 31-1 to complete the tight locking of the pipe.

[0042] Example 2

[0043] Reference Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, there are several first movable slots 11-1, and they are arranged in a circular array outside the second movable slot 11-2. The first movable slot 11-1 and the second movable slot 11-2 have the same size.

[0045] Specifically, there are several clamping components 2, which are symmetrically distributed on the outside of the first movable groove 11-1 and the second movable groove 11-2. The clamp housing 31 is in sliding contact with the first movable groove 11-1 and the clamp housing 31 is in sliding contact with the second movable groove 11-2.

[0046] When the fixture housing 31 slides along the first movable groove 11-1 or the second movable groove 11-2, the handles 25 on both sides rotate simultaneously, squeezing and pushing the squeezing column 24 to slide, applying pressure to the fixture housing 31 synchronously, and completing the locking.

[0047] Specifically, an extrusion block 26 is fixed on the extrusion column 24, one end of the first spring 27 is fixed on the extrusion block 26, and the other end of the first spring 27 is fixed on the support base 21.

[0048] When the drive handle 25 rotates, it rotates eccentrically on the fixed rod 23 in the cooperation of the eccentric shaft hole 25-1, thereby pushing the extrusion column 24 to slide, causing the first spring 27 to compress and store energy, and the extrusion column 24 to move and press against the clamp housing 31, greatly increasing the friction force that the clamp housing 31 needs to overcome, and completing the anti-slip locking.

[0049] The toothed plate 12 includes a first fixing plate with toothed grooves in the upper half and a second fixing plate with smooth lower half. The bottom of the first fixing plate is fixedly connected to the top of the second fixing plate. The first fixing plate meshes with the gear 32, while the second fixing plate does not contact the gear 32.

[0050] When in use, first install the clamping component 3 into the first movable groove 11-1 and slide it downward. At this time, the gripper 36 expands outward and the second spring 33 is stretched until the gear 32 is moved to the position of the second fixed plate on the toothed plate 12. At this time, the gear 32 does not mesh with the first fixed plate on the toothed plate 12. Under the action of the second spring 33, the clamping arm 35 and the gripper 36 automatically reset.

[0051] Then, the tube head is placed between the jaws 36. The size of the tube head is larger than the distance between the two jaws 36 in their natural state. The tube head will expand outward against the jaws 36, and the clamping arm 35 will rotate synchronously. Under the elastic connection of the second spring 33, the jaws 36 will pre-clamp and position the tube head, automatically adapting to the tube diameter.

[0052] Then the clamp housing 31 is moved upward, and the gear 32 moves upward to mesh with the toothed plate 12, causing the two clamping arms 35 to rotate inward at the same time, and the clamping jaws 36 lock the tube head.

[0053] Finally, the drive handle 25 is rotated, pressing the extrusion column 24 to move, thus locking the fixture housing 31, ensuring the stability of the fixture housing 31 in position, as well as the stability of the pipe head clamping, to meet the requirements of subsequent stable welding.

[0054] After the above operations are completed, according to the installation position of the clamping component 3 on the first movable groove 11-1, and in conjunction with the clamping component 3 in the second movable groove 11-2, a fixed angle is formed between the two pipe fittings. At this time, the corresponding bend head can be sleeved on the pipe fitting, and then welding operations can be performed. Alternatively, the two matching bend heads can be directly welded and fixed.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
