Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial welding devices, in particular to a welding arc clamping device. Background Art
[0002] Existing arc welding clamping devices typically consist of a base plate and a mounting plate fixed atop the base plate. The mounting plate is equipped with a limit clamping structure to limit the outer side of the arc workpiece, a support structure to support the arc workpiece, and a clamping plate sliding on the base plate. When clamping the arc workpiece, if the workpiece is a thin-walled circular ring, this type of arc welding clamping device structure can easily deform and damage the workpiece, making quality assurance difficult. Furthermore, the point contact between the fixture and the workpiece can easily damage the workpiece surface. Heat dissipation is also inadequate. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of the above-mentioned existing technologies and to provide a welding arc clamping device with simpler clamping and heat dissipation, which can wrap the product and quickly cool it down during production. It will not leave scars on the product surface during clamping, and can improve efficiency and pass rate.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a welding arc clamping device, which is provided with a base plate, and a first plasma welding chuck plate is fixed at one end of the base plate; a guide rail is provided at the other end of the base plate, and a slide is provided on the guide rail, and the slide can move back and forth on the guide rail, and the second plasma welding chuck plate is fixed on the slide, and the first plasma welding chuck plate and the second plasma welding chuck plate are connected by a double hook spring; the first plasma welding chuck plate and the second plasma welding chuck plate each have a notch, and when the first plasma welding chuck plate and the second plasma welding chuck plate are pulled together by the double hook spring to close the mold, the gap between the two can clamp the workpiece.
[0005] The notch is a shape that matches the outer diameter of the workpiece.
[0006] Preferably, after the first plasma welding chuck plate and the second plasma welding chuck plate are molded together, the notch completely wraps the workpiece in the middle of the mold and contacts the edge of the mold, and has a semicircular shape that matches the outer diameter of the workpiece.
[0007] Furthermore, the notch is semicircular.
[0008] Among them, the double-hook springs are arranged in parallel on both sides of the first plasma welding chuck plate and the second plasma welding chuck plate. In the original position of the double-hook springs, the first plasma welding chuck plate and the second plasma welding chuck plate are pulled together by the double-hook springs to close the mold. When the double-hook springs are pulled apart, the first plasma welding chuck plate and the second plasma welding chuck plate are separated, and the second plasma welding chuck plate is fixed on the slide along the guide rail away from the first plasma welding chuck plate.
[0009] Compared to existing technology, the arc workpiece welding clamping fixture of the present invention uses a limited clamping structure to initially limit the arc workpiece's two sides, and a support structure to support the workpiece's inner surface. This allows the support plate to support the arc workpiece while the driving mechanism drives the clamping plate to clamp and secure it, effectively preventing damage to the arc workpiece caused by excessive external forces. Furthermore, the position of both the limited plate and the support plate are adjustable, making it easy to clamp and secure arc workpieces of varying sizes and curvatures.
[0010] The significance of this utility model is also to provide a welding arc clamping device that is simpler to clamp and dissipate heat. The structure of this utility model has a large contact surface with the metal of the product, which can be wrapped around the product to quickly cool it down during production. The clamping will not leave scars on the product surface, which can improve efficiency and pass rate.

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents selected embodiments of the present invention.

[0015] In order to make the technical problems to be solved by the present invention, the technical solutions proposed, and their beneficial effects more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. The scope of protection of the present invention is not limited by the specific embodiments.
[0016] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the utility model. Figure 1 The device primarily comprises a first plasma welding chuck plate 1 (designed as a semicircular shape with the same outer diameter as the workpiece), a second plasma welding chuck plate 2 (designed as a semicircular shape with the same outer diameter as the workpiece), a base plate 3, two double-hook springs 4, a slide 5, and guide rails 6. The base plate 3 is fixed to the equipment table, while the second plasma welding chuck plate 2 is fixed to the slide 5, which can move back and forth on the guide rails 6. Double-hook springs 4 are attached to the left and right sides of the second plasma welding chuck plate 2, which is also fixed to the first plasma welding chuck plate 1. The first plasma welding chuck plate 1 and the second plasma welding chuck plate 2 are clamped together, primarily relying on the tension of the double-hook springs 4. After the first and second plasma welding chuck plates 1 and 2 are clamped together, the finished product is completely enclosed in the center of the mold hole and contacts the hole wall. This prevents the first and second plasma welding chuck plates 1 and 2 from falling out when clamped together, and allows for rapid dissipation of high temperatures during welding.
[0017] The double-hook spring 4 is arranged in parallel on both sides of the first plasma welding chuck plate 1 and the second plasma welding chuck plate 2. In the original position of the double-hook spring 4, the first plasma welding chuck plate 1 and the second plasma welding chuck plate 2 are pulled together by the double-hook spring 4 to close the mold. When the double-hook spring 4 is pulled open, the first plasma welding chuck plate 1 and the second plasma welding chuck plate 2 are separated, and the second plasma welding chuck plate 2 is fixed on the slide 5 and moves away from the first plasma welding chuck plate 1 along the guide rail 6.
[0018] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and exemplary embodiments. They can be applied to a variety of fields suitable for the present invention. Further modifications will be readily apparent to those skilled in the art.
