Description

Technical Field

[0001] This utility model relates to the field of resistance welding transformer technology, specifically a tooling for welding the secondary tube of a resistance welding transformer. Background Technology

[0002] The working principle of resistance welding transformer secondary tube welding is to melt the metal by using the resistance heat generated when current passes through the conductor. Resistance welding transformer secondary tube welding is a commonly used welding method that uses resistance heat to weld metal pipes together.

[0003] The existing tooling for welding the secondary tubes of resistance welding transformers cannot protect personnel and the surrounding environment during use. This results in welding spatter and sparks causing injury to personnel. Furthermore, the welding process involves placing the device on a flat surface and welding it with the equipment, which reduces the welding stability and presents limitations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tooling for welding the secondary tubes of a resistance welding transformer, which has the advantages of providing protection during welding and increasing welding stability, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a tooling for welding the secondary tube of a resistance welding transformer, comprising a platform, a motor fixedly installed on the inner wall of the platform, a lead screw fixedly mounted on the power output shaft of the motor, a slider threadedly connected to the outer wall of the lead screw, a protective plate fixedly installed on the outer wall of the slider, a stabilizing plate fixedly installed on the top of the platform, a support block fixedly installed on the top of the platform, a screw threadedly connected to the inner wall of the support block, a stabilizing block mounted on the outer wall of the screw, a first connecting rod rotatably connected to the outer wall of the stabilizing block, a baffle rotatably connected to the outer wall of the first connecting rod, a spring fixedly installed on the outer wall of the baffle, a fixing rod fixedly installed on the outer wall of the baffle, a support plate fixedly installed on the outer wall of the fixing rod, a second connecting rod rotatably connected to the outer wall of the first connecting rod, a through plate fixedly installed on the top of the platform, a handle fixedly installed on the outer wall of the screw, a controller fixedly installed on the outer wall of the protective plate, and a support rod fixedly connected to the bottom of the platform.

[0006] As a preferred technical solution of this utility model: a sliding groove is fixedly installed on the top of the platform, and the inner wall of the sliding groove is slidably connected to the bottom of the stabilizing block.

[0007] As a preferred technical solution of this utility model: the outer wall of the second connecting rod is rotatably connected to the outer wall of the stabilizing block, and the second connecting rod is rotatably connected to another baffle.

[0008] As a preferred technical solution of this utility model: the outer wall of the fixing rod is slidably sleeved with the inner wall of the through plate, and the other end of the spring is fixed to the outer wall of the through plate.

[0009] As a preferred technical solution of this utility model: the controller and the motor are electrically connected, the lead screw is composed of a positive thread rod and a negative thread rod, and the outer walls of the positive thread rod and the negative thread rod are respectively threaded to the inner wall of the slider.

[0010] As a preferred technical solution of this utility model: the number of protective plates is two, and the two protective plates are symmetrically arranged with the motor as the center, and the outer wall of the protective plate is slidably connected to the outer wall of the platform.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This fixture for welding the secondary tube of a resistance welding transformer uses a controller to drive a motor to rotate a lead screw. The positive and negative threaded rods drive the sliders to move closer to each other. When the motor drives the lead screw to rotate in the opposite direction, the sliders separate. Two protective plates are symmetrically arranged around the motor, allowing them to slide on the outer wall of the platform via the sliders, thus providing welding protection for the top of the platform.

[0013] 2. This fixture for welding the secondary tube of a resistance welding transformer uses an externally rotated handle to drive a screw to connect to the inner wall of the support block. This causes the screw to slide along the inner wall of the groove, thus limiting the movement of the screw and preventing deviation of the trajectory. The stability block drives the second and first connecting rods to rotate. Depending on the size of the component to be welded, a fixing rod pushes the support plate closer to the outer wall of the stability plate to achieve clamping. The second and first connecting rods drive the baffle to press against the spring, compressing the spring. The fixing rod then clamps and fixes the support plate and the component. The spring force provides vibration damping and buffering during the welding process. Attached Figure Description

A motor 8 is fixedly mounted on the inner wall of the platform 1. A lead screw 9 is fixedly mounted on the power output shaft of the motor 8. A slider 19 is threadedly connected to the outer wall of the lead screw 9. A protective plate 2 is fixedly mounted on the outer wall of the slider 19. A stabilizing plate 18 is fixedly mounted on the top of the platform 1. A support block 6 is fixedly mounted on the top of the platform 1. A screw 7 is threadedly connected to the inner wall of the support block 6. A stabilizing block 16 is mounted on the outer wall of the screw 7. A rotating connection is made to the outer wall of the stabilizing block 16. A first connecting rod 15 is rotatably connected to a baffle 14 on its outer wall. A spring 11 is fixedly installed on the outer wall of the baffle 14. A fixing rod 20 is fixedly installed on the outer wall of the baffle 14. A support plate 13 is fixedly installed on the outer wall of the fixing rod 20. A second connecting rod 17 is rotatably connected to the outer wall of the first connecting rod 15. A through plate 12 is fixedly installed on the top of the platform 1. A handle 5 is fixedly installed on the outer wall of the screw 7. A controller 3 is fixedly installed on the outer wall of the protective plate 2. A support rod 4 is fixedly connected to the bottom of the platform 1.

[0022] In the above structure, by installing the stabilizing plate 18, the welding device is placed between the support plate 13 and the stabilizing plate 18, and the support plate 13 pushes the device to abut against the stabilizing plate 18 to achieve clamping stability.

[0023] In a preferred embodiment, a slide groove 10 is fixedly installed on the top of the platform 1, and the inner wall of the slide groove 10 is slidably connected to the bottom of the stabilizing block 16.

[0024] In the above structure, by rotating the handle 5 with external force, the handle 5 drives the screw 7 to make a threaded connection on the inner wall of the support block 6, so that the screw 7 drives the stabilizing block 16 to slide on the inner wall of the slide groove 10, thereby causing the screw 7 to push the stabilizing block 16 to limit the movement and prevent the movement trajectory from deviating.

[0025] In a preferred embodiment: the outer wall of the second connecting rod 17 is rotatably connected to the outer wall of the stabilizing block 16, and the second connecting rod 17 is rotatably connected to another baffle 14.

[0026] In the above structure, the second connecting rod 17 and the first connecting rod 15 are rotated by the stabilizing block 16. According to the volume of the component to be welded, the support plate 13 is pushed close to the outer wall of the stabilizing plate 18 by the fixing rod 20 to achieve clamping stability.

[0027] In a preferred embodiment: the outer wall of the fixing rod 20 is slidably connected to the inner wall of the through plate 12, and the other end of the spring 11 is fixed to the outer wall of the through plate 12.

[0028] In the above structure, the other end of the spring 11 is fixed to the outer wall of the through plate 12. The second connecting rod 17 and the first connecting rod 15 drive the baffle 14 to abut against the spring 11, so that the spring 11 is compressed. The fixing rod 20 drives the support plate 13 to clamp and fix the device. The elastic force of the spring 11 enables vibration reduction and buffering during the welding process.

[0029] In a preferred embodiment: the controller 3 and the motor 8 are electrically connected, the lead screw 9 is composed of a positive thread and a negative thread, and the outer walls of the positive thread and the negative thread are respectively threaded to the inner wall of the slider 19.

[0030] In the above structure, the motor 8 drives the lead screw 9 to rotate by the control controller 3. The positive thread rod and the negative thread rod drive the slider 19 to move closer to each other. When the motor 8 drives the lead screw 9 to rotate in the opposite direction, the slider 19 separates towards each other.

[0031] In a preferred embodiment, there are two protective plates 2, and the two protective plates 2 are symmetrically arranged with the motor 8 as the center. The outer wall of the protective plate 2 is slidably connected to the outer wall of the platform 1.

[0032] In the above structure, two protective plates 2 are symmetrically arranged around the motor 8, so that the two protective plates 2 slide on the outer wall of the platform 1 via the slider 19, thereby providing welding protection for the top welding of the platform 1.

[0033] Working principle: The controller 3 drives the motor 8 to rotate the lead screw 9. The positive and negative threaded rods respectively drive the sliders 19 closer together. When the motor 8 drives the lead screw 9 to rotate in the opposite direction, the sliders 19 separate. Two protective plates 2 are symmetrically arranged around the motor 8, allowing them to slide on the outer wall of the platform 1 via the sliders 19. This provides welding protection to the top of the platform 1. External force rotates the handle 5, causing the screw 7 to connect threadedly to the inner wall of the support block 6. The screw 7 then drives the stabilizing block 16 in the groove. The inner wall of 10 slides, thereby causing the screw 7 to push the stabilizing block 16 to limit the movement and prevent the movement trajectory from deviating. The stabilizing block 16 drives the second connecting rod 17 and the first connecting rod 15 to rotate. According to the volume of the component to be welded, the fixing rod 20 pushes the support plate 13 to approach the outer wall of the stabilizing plate 18 to achieve clamping. The second connecting rod 17 and the first connecting rod 15 drive the baffle 14 to abut against the spring 11, so that the spring 11 is compressed. The fixing rod 20 drives the support plate 13 to clamp and fix the component. The elastic force of the spring 11 enables vibration reduction and buffering during the welding process.
