[0002] Currently, welding equipment is a general term for various tools and machines used to complete welding processes, mainly including types such as electric arc welding, gas shielded welding, resistance welding, laser welding, ultrasonic welding, and friction welding. Its core components include a power supply, welding torch or welding gun, wire feeder, cooling system, and control system. It also needs to be equipped with auxiliary tools such as protective equipment, fixtures, positioners, and testing equipment.

[0003] In practical applications, metal rings need to be welded. The manufacturing process of metal rings includes steps such as raw material preparation, forming, processing and treatment, quality control, and post-processing. First, a suitable metal material is selected according to the requirements and cut into blanks. Then, the blanks are bent to form a ring shape.

[0004] During the welding process of the metal ring, the workers manually pick up the ring and then face the joint of the ring toward the welding equipment, which then welds the joint of the metal ring.

[0005] Regarding the aforementioned technologies, the inventors believe that when manually handling the metal ring for welding, the position of the metal ring is prone to shift, which in turn affects the welding effect of the metal ring. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a clamping mechanism for a metal ring welding equipment, which solves the technical problem that the position of the metal ring is easily displaced when the metal ring is manually picked up for welding, thereby affecting the welding effect of the metal ring.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A clamping mechanism for a metal ring welding device includes a frame for supporting the clamping mechanism. The frame is characterized by having a support base on which a metal ring is placed; a first clamping assembly and a second clamping assembly on the frame, which clamp the metal ring onto the support base; and a positioning assembly on the frame for positioning the metal ring.

[0010] Furthermore, the positioning assembly includes a positioning cylinder and a positioning plate. The positioning cylinder is mounted on the frame, the positioning plate slides between the two support seats, and the positioning plate is mounted on the piston rod of the positioning cylinder.

[0011] Furthermore, the first clamping assembly includes a first clamping cylinder, one end of which faces the side close to the support base, and a first clamping plate is provided at one end of the piston rod of the first clamping cylinder.

[0012] Furthermore, the second clamping assembly includes a second clamping cylinder, one end of which faces the side close to the support base, and a second clamping plate is provided at one end of the piston rod of the second clamping cylinder.

[0013] Furthermore, a sliding cylinder is provided on the frame, the sliding cylinder is mounted on the frame, and one end of the piston rod of the sliding cylinder is connected to the second clamping cylinder.

[0025] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a clamping mechanism for a metal ring welding equipment.

[0028] Reference Figure 1 A clamping mechanism for a metal ring welding device includes a frame 1 with a support base 2 on the frame 1, on which a metal ring is placed. A positioning assembly 3 is provided on the frame 1 to position both ends of the metal ring. A first clamping assembly 4 and a second clamping assembly 5 are also provided on the frame 1 to clamp the metal ring onto the support base 2. After the metal ring is fixed on the frame 1, the ends of the metal ring are welded using welding equipment.

[0029] Reference Figure 2 During processing, the metal ring is formed by bending a metal strip into a ring. When in use, the two ends of the metal ring need to be welded. To improve the stability of the metal ring on the support base 2, two support bases 2 are spaced apart on the frame 1. During use, the two ends of the metal ring rest on the support base 2. Since the cross-section of the metal ring is circular, to further enhance the stability of the metal ring resting on the support base 2, both support bases 2 have a supporting arc surface 21, and the two ends of the metal ring rest on the supporting arc surface 21 of the support base 2.

[0030] Reference Figure 3Furthermore, to improve the accuracy of the welding equipment in positioning the two ends of the metal ring, the positioning assembly 3 includes a positioning cylinder 31 and a positioning plate 32. The positioning cylinder 31 is horizontally mounted on the frame 1, with one end of the piston rod of the positioning cylinder 31 facing towards the side closest to the two support seats 2. The positioning plate 32 is located between the two support seats 2 and is connected to the piston rod of the positioning cylinder 31. In use, the positioning plate 32 slides away from or towards the support seat 2 via the positioning cylinder 31. During processing, the metal ring is elastic. When the stress of the metal ring when it unfolds does not exceed the elastic limit, the metal ring will attempt to return to its original shape. When the metal ring is placed on the support seat 2, both ends of the metal ring are pressed against the sides of the positioning plate 32 in the thickness direction. When welding is required on the metal ring, the positioning plate 32 moves away from the support seat 2 under the drive of the positioning cylinder 31, and then the welding equipment welds the metal ring.

[0031] Reference Figure 4 To improve the stability of the metal ring on the frame 1, the first clamping assembly 4 includes a first clamping cylinder 41, which is fixedly mounted on the frame 1. The first clamping cylinder 41 corresponds to one of the support seats 2, and the angle between the first clamping cylinder 41 and the support seat 2 in the horizontal direction is 45 degrees. One end of the piston rod of the first clamping cylinder 41 faces the side closer to the support seat 2, and a first clamping plate 42 is provided at one end of the piston rod of the first clamping cylinder 41. The first clamping plate 42 clamps the metal ring on the support seat 2.

[0032] A slide plate 11 is provided on the frame 1. The slide plate 11 slides horizontally toward or away from the support seat 2 corresponding to the first clamping cylinder 41. A sliding cylinder 12 is provided on the frame 1. The sliding cylinder 12 is horizontally installed on the frame 1, and one end of the piston rod of the sliding cylinder 12 is connected to the slide plate 11. In use, the sliding cylinder 12 drives the slide plate 11 to slide on the frame 1.

[0033] Another support 2 is installed on the slide plate 11. When in use, the sliding cylinder 12 drives the support block on the slider to move closer to the support 2 on the opposite side. After the metal ring is placed on the two support 2, the sliding cylinder 12 drives the slide plate 11 to move away from the support 2 on the opposite side, so that the metal ring can maintain a ring shape when it is placed on the two support 2, thus improving the convenience of placing the metal ring on the two support 2.

[0034] Furthermore, the second clamping assembly 5 includes a second clamping cylinder 51, which is mounted on the slide plate 11. The angle between the second clamping cylinder 51 and the horizontal direction of the support seat 2 on the slide plate 11 is 45 degrees, and one end of the piston rod of the second clamping cylinder 51 faces the side closer to the support seat 2. In addition, a second clamping plate 52 is provided at one end of the piston rod of the second clamping cylinder 51, which clamps the metal ring onto the support seat 2. The angle between the first clamping cylinder 41 and the second clamping cylinder 51 is 90 degrees. The first clamping cylinder 41 and the second clamping cylinder 51 drive the first clamping plate 42 and the second clamping plate 52 to clamp the metal ring onto the two support seats 2.

[0035] To prevent the metal ring from shifting in position on the support base 2, thus affecting the clamping of the metal ring by the first clamping plate 42 and the second clamping plate 52, guide slopes 43 are formed on the side of the first clamping plate 42 and the second clamping plate 52 closest to the support base 2. When the metal ring shifts in position, as the first clamping plate 42 and the second clamping plate 52 move towards the support base 2, the guide slopes 43 on the first clamping plate 42 and the second clamping plate 52 guide the metal ring, thereby improving the stability of the metal ring's position on the support base 2.

[0036] During the welding process of the metal ring, a large amount of welding fumes are generated. To reduce the impact of welding fumes on the workers, a dust collection hood 13 is installed on the frame 1. The dust collection hood 13 is located between the two support bases 2. In use, the dust collection hood 13 is connected to an external air extraction device, and the welding fumes generated during the metal ring welding process are collected by the dust collection hood 13. In addition, to reduce the impact of the dust collection hood 13 on the welding equipment, a clearance groove 131 is formed on the dust collection hood 13. In use, the external welding equipment welds the metal ring between the two support bases 2 through the clearance groove 131.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
