[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a mechanical parts welding device, including a welding device body, the welding device body includes a box body 1, both ends of the box body 1 are movably mounted with a movable seat 2, a displacement mechanism 4 is fixedly mounted on the movable seat 2, the displacement mechanism 4 is an electric push rod, the electric push rod later pushes the support assembly 3 to adjust its position inside the pipeline 16, so as to effectively support the pipeline 16, one end of the displacement mechanism 4 is fixedly mounted with a support assembly 3, the support assembly 3 is movably mounted inside the box body 1, a support seat 5 is fixed at the bottom of the box body 1, a fixing frame 20 is welded on the side of the box body 1, a welding mechanism 21 is movably mounted on the fixing frame 20, a movable column 7 is installed on the displacement mechanism 4, the support assembly 3 includes a fixed plate 8, the fixed plate 8 is fixed to one end of the movable column 7, the welding mechanism 21 is a welding gun, and the welding gun is placed on the fixing frame 20 when not in use, so as to facilitate taking it out when in use later.

[0025] In this embodiment, a rotating disk 9 is movably installed on one side of the fixed disk 8, and a fixing groove 10 is opened on both the rotating disk 9 and the fixed disk 8, and a roller 11 is movably installed inside the fixed groove 10. A power mechanism 12 is fixedly installed on the fixed disk 8, and the power mechanism 12 is a DC motor. The DC motor drives the rotating disk 9 to rotate, and the rotating disk 9 realizes the synchronous rotation of the pipeline 16 through the roller 11. One side of the rotating disk 9 is fixedly installed on the power mechanism 12, and a slide groove is opened on the inner wall of the fixed groove 10. A slider 13 is movably installed inside the slide groove. The slider 13 is installed inside the slide groove through a supporting mechanism 15. The supporting mechanism 15 is a supporting spring. The supporting spring always moves upward through the slider 13. The roller 11 on the slider 13 squeezes and contacts the inner wall of the pipeline 16, and the pipeline 16 is rotated for use later under the push of the roller 11.

[0026] In this embodiment, a lifting mechanism 19 is fixedly installed inside the box body 1. The lifting mechanism 19 is an electric push rod. The electric push rod pushes the roller 18 to move up and down. The up and down movement of the roller 18 is slightly adjusted in height according to the diameter of the pipe 16. A U-shaped frame 17 is fixed on the lifting mechanism 19. The roller 18 is rotatably installed on the U-shaped frame 17. The pipe 16 is installed on the roller 18. The pipe 16 is movably installed on the support assembly 3. A cavity is opened inside the box 1. A connecting seat 6 is movably installed inside the cavity. A tension spring is fixed at one end of the connecting seat 6. One end of the tension spring is fixed on the inner wall of the cavity. A rotating shaft 14 is rotatably installed on the slider 13. The rotating shaft 14 is installed at both ends of the roller 11. The tension spring drives the connecting seat 6 to move inward. The inward movement of the connecting seat 6 pushes the pipe 16 inward, so that the two ends of the pipe 16 are squeezed and contacted, which is convenient for subsequent welding alignment.

[0027] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When using the device, first move the movable seat 2 to both sides, and the movable seat 2 drives the connecting seat 6 to be pulled out from the inside of the box body 1. After being pulled out, the overall width between the movable seats 2 increases, and the two pipes 16 are placed on the top of the roller 18. The lifting mechanism 19 pushes the U-shaped frame 17 to move up and down. The movement of the U-shaped frame 17 adjusts the height of the roller 18 and the pipe 16, so that the center of the pipe 16 is aligned with the support component 3. After the height adjustment of the pipe 16 is completed, the displacement mechanism 4 is started to push the fixed disk 8 and the rotating disk 9 into the inside of the pipe 16. After the fixed disk 8 and the rotating disk 9 enter the inside of the pipe 16, the inner wall of the pipe 16 squeezes the roller 11, and the roller 11 moves downward in the fixed groove 10 through the slider 13, and the roller 11 is moved downward to adjust the roller 1 1, so that the roller 11 fits the inner wall of the pipe 16 and moves left and right. When the fixed disk 8 and the rotating disk 9 are respectively moved to one end of the inside of the pipe 16, the support assembly 3 and the roller 18 realize the upper and lower limit between the pipe 16, and the movable seat 3 is released. The movable seat 3 moves inward under the drive of the connecting seat 6. The inner wall of the movable seat 2 cooperates with one end of the pipe 16. The movable seat 2 pushes the pipe 16 to move inward and squeezes and aligns. After alignment, the position of the support assembly 3 is adjusted again, so that the support assembly 3 moves to the inside of the pipe 16 respectively, and then the power mechanism 12 is started. The power mechanism 12 drives the rotating disk 9 to rotate. The rotating disk 9 uses the roller 11 as a support point, and drives the pipe 16 to rotate slowly under the friction between the roller 11 and the inner wall of the pipe 16. The pipe 16 rotates synchronously to complete the welding of one circle at the gap, which is convenient for increasing the welding speed.
