Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding tooling technology, and in particular to a welding tooling for processing upright poles. Background Technology
[0002] Welding fixtures are a set of flexible welding fixtures for fixing, clamping, and positioning. They are mainly used for welding various weldable materials, including large, medium, and small materials.
[0003] However, in the existing technology, when welding two uprights, welding fixtures are generally used to fix and position the two uprights to ensure that the welding ends of the two uprights can be accurately positioned. Since the uprights are mostly cylindrical, when welding them, workers often need to hold the welding gun and move around the welding seam of the upright at a uniform speed. Such welding operations are difficult and prone to welding errors. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies: since most uprights are cylindrical, welding them often requires workers to hold a welding torch and move it around the weld seam of the upright at a constant speed, which is difficult and prone to welding errors.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a welding fixture for pole processing, comprising a welding fixture table, a mounting bracket fixedly connected to the lower surface of the welding fixture table, and a lower insert plate rotatably penetrating the middle end of the mounting bracket, and a passage opening being provided on the surface of the welding fixture table directly above the lower insert plate, a first motor fixedly connected to the lower end of the mounting bracket, and the output shaft of the first motor being fixedly connected to the lower insert plate, an electric telescopic rod fixedly fixed to the upper surface of the welding fixture table, and a fixing plate fixedly fixed to one end of the electric telescopic rod, an upper insert plate rotatably penetrating one end of the fixing plate, a second motor fixedly fixed to the upper surface of the fixing plate, and the output shaft of the second motor being fixedly connected to the upper insert plate, and pole bodies being engaged and connected to the surfaces of both the lower and upper insert plates.
[0006] In a preferred embodiment, a placement platform is fixedly connected to the support leg at the lower end of the welding fixture.
[0007] In a preferred embodiment, the welding fixture is provided with a positioning ring directly above the passage opening, and both ends of the positioning ring are fixed with support frames, one end of which is fixedly connected to the welding fixture.
[0008] In a preferred embodiment, rotating rollers are rotatably connected to both the passage opening and the surface of the positioning ring, and several rotating rollers are equidistantly arranged around the surface of the passage opening and the positioning ring.
[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0010] This invention involves engaging one end of each of the two uprights to be welded onto a lower and upper insert plate, respectively. Then, by retracting the electric telescopic rod, the fixing plate descends as a whole, causing the upper insert plate, a second motor, and the uprights connected to the upper insert plate to descend as well. This allows the welding ends of the two uprights to fit tightly together. Finally, by having the first and second motors rotate the lower and upper insert plates and the two uprights in the same direction, the operator no longer needs to hold a welding torch and weld around the uprights, reducing the difficulty of the welding operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1
[0018] like Figure 1-3As shown, this utility model provides a technical solution: a welding fixture for pole processing, including a welding fixture table 1. A mounting bracket 2 is fixedly connected to the lower surface of the welding fixture table 1. With the help of the mounting bracket 2, the rotational stability of the lower insertion plate 3 is improved. The lower insertion plate 3 is rotatably passed through the middle end of the mounting bracket 2. An opening is provided on the surface of the welding fixture table 1 directly above the lower insertion plate 3. By passing the lower half of the pole body 13 through the opening and engaging one end with the lower insertion plate 3, the pole body 13 can be stably erected, facilitating its subsequent stable rotation. A first motor 4 is fixedly connected to the lower end of the mounting bracket 2, and the output shaft of the first motor 4 is fixedly connected to the lower insertion plate 3. The first motor 4 drives the lower insertion plate 3 to rotate, thereby achieving the effect of rotating the lower half of the pole body 13. An electric telescopic rod 9 is fixed to the upper surface of the welding fixture table 1, and a fixing plate 10 is fixed to one end of the electric telescopic rod 9. One end of the 0 rotates through the upper insertion plate 11. By engaging one end of the upper pole body 13 with the upper insertion plate 11, and then retracting the electric telescopic rod 9, the fixing plate 10 is lowered as a whole. This causes the upper insertion plate 11, the second motor 12, and the pole body 13 connected to the upper insertion plate 11 to descend, allowing the welding ends of the two pole bodies 13 to fit tightly together, facilitating subsequent welding operations. The second motor 12 is fixed on the upper surface of the fixing plate 10, and the output shaft of the second motor 12 is fixedly connected to the upper insertion plate 11. The second motor 12 drives the upper insertion plate 11 to rotate, thereby achieving the effect of rotating the upper pole body 13. The pole bodies 13 are engaged and connected to the surfaces of the lower insertion plate 3 and the upper insertion plate 11. By having the first motor 4 and the second motor 12 drive the lower insertion plate 3, the upper insertion plate 11, and the two pole bodies 13 to rotate in the same direction, the operator does not need to hold a welding gun to weld around the pole body 13, reducing the difficulty of welding operations.
[0019] Example 2
[0020] like Figure 1-3As shown, a placement platform 5 is fixedly connected to the lower leg of the welding fixture 1. The placement platform 5 provides a platform for placing the tools needed during welding operations, making it convenient for operators to access and use them. A positioning ring 7 is set directly above the passage opening of the welding fixture 1, and support frames 6 are fixed to both ends of the positioning ring 7. One end of the support frame 6 is fixedly connected to the welding fixture 1. The support frame 6 supports the positioning ring 7, while the positioning ring 7 positions the upper half of the upright body 13, allowing the upper half of the upright body 13 to be stably connected to the lower half of the upright body 13. Rotary rollers 8 are rotatably connected to both the passage opening and the surface of the positioning ring 7. Several rotating rollers 8 are equidistantly arranged around the surface of the passage opening and the positioning ring 7. With the help of the rotating rollers 8, the resistance encountered by the upright body 13 when rotating at the passage opening and the positioning ring 7 is reduced, and the smoothness of the rotation of the upright body 13 is improved.
[0021] Working principle:
[0022] like Figure 1-3 As shown, when using this utility model, the user first passes the lower half of the upright body 13 downward through the positioning ring 7, allowing it to pass through the passage opening, and then engages one end of the lower half of the upright body 13 with the lower insert plate 3. Next, the upper half of the upright body 13 passes downward through the positioning ring 7, bringing the welding ends of the two upright bodies 13 into contact. Then, by retracting the electric telescopic rod 9, the fixing plate 10 descends as a whole. The descent of the fixing plate 10 drives the upper insert plate 11 and the second motor 12 to descend as well. Finally, the upper insert plate 11 engages with one end of the upper half of the upright body 13. Then, by having the first motor 4 and the second motor 12 drive the lower insert plate 3, the upper insert plate 11, and the two upright bodies 13 to rotate in the same direction, the operator no longer needs to hold a welding torch to weld around the upright body 13, reducing the difficulty of the welding operation.
[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
