[0031] 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.

[0032] Reference Figures 1-3 An embodiment of this utility model provides a clamping device for welding processing, including a base 1, a motor 2 fixedly connected to the side wall of the base 1, a bidirectional threaded rod 3 fixedly connected to the output end of the motor 2, a threaded sleeve 4 slidably connected to the inner wall of the base 1, the bidirectional threaded rod 3 passing through and rotatably connected to the inner wall of the base 1, the bidirectional threaded rod 3 and the threaded sleeve 4 being threadedly connected, starting the motor 2 to drive the bidirectional threaded rod 3 to rotate, and at the same time the bidirectional threaded rod 3 rotates, it will drive the two sets of threaded sleeves 4 threadedly connected to it to slide synchronously in opposite directions on the inner wall of the base 1, and a positioning mechanism 5 and a clamping mechanism 6 are provided on the top of the base 1.

[0033] Reference Figures 2-4, the positioning mechanism 5 includes a sliding table 51. The sliding table 51 is fixedly connected to the top of the threaded sleeve 4. The inner wall of the sliding table 51 penetrates and is slidably connected to a clamping plate 52. The side of the plate can be clamped by the clamping plate 52. The clamping plate 52 is an "L"-shaped plate structure. A return spring 53 is fixedly connected to the inner wall of the clamping plate 52. The end of the return spring 53 away from the clamping plate 52 is fixedly connected to the side wall of the sliding table 51. Under the connection of the return spring 53, when the sliding table 51 slides, it will带动 the clamping plate 52 to move synchronously, and the elastic force of the return spring 53 can带动 the clamping plate 52 to slide back to its original position. A bent rod 54 is hinged to the side wall of the clamping plate 52. When the push rod 57 moves along the inner wall of the chute 56, it will push the bent rod 54, causing the bent rod 54 to rotate on the side wall of the clamping plate 52. The end of the bent rod 54 away from the sliding table 51 is fixedly connected to a pressing rod 55. Through the rotation of the bent rod 54 and the cooperation of the pressing rod 55, the top of the plate can be limited. A chute 56 is opened on the bent rod 54. A push rod 57 is fixedly connected to the side wall of the sliding table 51. The push rod 57 is a "U"-shaped rod structure. The outer wall of the push rod 57 fits against the inner wall of the chute 56. When the clamping plate 52 is blocked by the plate, when the sliding table 51 slides, it will带动 the push rod 57 to move along the inner wall of the chute 56.

[0034] Refer to Figures 2-3 , the pressing mechanism 6 includes a sliding rod 61. The sliding rod 61 penetrates and is slidably connected to the inner wall of the base 1. A top rod 62 penetrates and is slidably connected to the inner wall of the sliding rod 61. The sliding rod 61 will带动 the top rod 62 to move synchronously. By the movement of the top rod 62, the two groups of plates placed on the base 1 can be pushed, so that the two groups of plates can approach each other. A limiting block 63 is fixedly connected to the end of the top rod 62 close to the sliding rod 61. A limiting spring 64 is fixedly connected to the side wall of the limiting block 63. The end of the limiting spring 64 away from the limiting block 63 is fixedly connected to the outside of the sliding rod 61. Using the elasticity of the limiting spring 64 and the cooperation of the limiting block 63, the top rod 62 can press against the plate, so that the two groups of plates can be kept in a fitting state, which is beneficial to improving the welding quality of the plates. A connecting rod 65 is hinged to the bottom of the sliding rod 61. A vertical rod 66 is fixedly connected to the bottom of the sliding table 51. The end of the vertical rod 66 away from the sliding table 51 is hinged to the connecting rod 65. When the sliding table 51 slides in the inner wall of the base 1, the sliding table 51 will带动 the vertical rod 66 to push the connecting rod 65, causing the connecting rod 65 to push the sliding rod 61. At this time, the sliding rod 61 will slide in the inner wall of the base 1.

[0035] Working principle: The welded plate is placed between two sets of slides 51. Then, the motor 2 is started, driving the bidirectional threaded rod 3 to rotate. The rotation of the bidirectional threaded rod 3 causes the two sets of threaded sleeves 4, which are threaded to it, to slide synchronously on the inner wall of the base 1 and move closer to each other. At this time, the two sets of threaded sleeves 4 will drive the two sets of slides 51 to move synchronously, thus bringing the two sets of slides 51 closer together. While sliding, the slides 51, under the connection of the return spring 53, will drive the clamping plate 52 to move synchronously. When the clamping plate 52 contacts the side wall of the plate during its movement, the plate's obstruction will prevent the clamping plate 52 from moving further. While the slide table 51 continues to slide, it will press the return spring 53. At the same time, the slide table 51 will drive the push rod 57 to move synchronously. As the push rod 57 moves, it will move against the inner wall of the slide groove 56 and push the bent rod 54, causing the bent rod 54 to rotate on the side wall of the clamping plate 52. As the bent rod 54 rotates, it will drive the pressure rod 55 to swing downward. When the pressure rod 55 swings downward and contacts the upper surface of the plate, it will press the plate downward. At this time, the pressure rod 55 can limit the top of the plate, and the clamping plate 52 can clamp the two sides of the plate, so that the plate can be clamped in two directions simultaneously.

[0036] When the pressure rod 55 swings downward and contacts the upper surface of the plate, the plate's obstruction prevents it from swinging further downward, thus preventing the bent rod 54 from rotating. Once the bent rod 54 cannot rotate, the slide groove 56 limits the push rod 57, preventing the slide table 51 from moving the push rod 57. With the push rod 57 unable to move, the slide groove 56, in conjunction with the bent rod 54, limits the clamping plate 52, maintaining a fixed distance between it and the slide table 51. This prevents the clamping plate 52 from sliding on the inner wall of the slide table 51, allowing the clamping plate 52 and the pressure rod 55 to provide stable and effective clamping of the plate.

[0037] When it is necessary to release the clamping of the plate, the motor 2 first drives the bidirectional threaded rod 3 to rotate, causing the two sets of threaded sleeves 4 to move the two sets of slides 51 away from each other. As the slides 51 move away from each other, they will gradually release the pressure of the return spring 53. At this time, under the elastic action of the return spring 53, the clamping plate 52 will still be attached to the side wall of the plate. Therefore, as the slides 51 slide, they will drive the push rod 57 to move against the inner wall of the slide groove 56. At the same time, the push rod 57 will push the bent rod 54, causing the bent rod 54 to rotate on the side wall of the clamping plate 52 and drive the pressure rod 55 to swing upward, so that the pressure rod 55 can release the restriction on the top of the plate. At the same time, with the movement of the slides 51 and the connection action of the return spring 53, the clamping plate 52 can be driven to detach from the side wall of the plate, thereby releasing the restriction on the side wall of the plate.

[0038] When the two sets of sliding tables 51 approach each other, the sliding tables 51 will drive the vertical rod 66 to push the connecting rod 65, so that the connecting rod 65 pushes the sliding rod 61. At this time, the sliding rod 61 will slide on the inner wall of the base 1 and gradually approach the base 1. At the same time, the sliding rod 61 will drive the top rod 62 to move synchronously. The movement of the top rod 62 can push the two sets of plates placed on the base 1, so that the two sets of plates can approach each other. At the same time, the elasticity of the limiting spring 64 and the limiting block 63 can make the top rod 62 press against the plate, so that the two sets of plates can be kept in a close fit so that the workers can weld the plates.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
