Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a fixing device for pipe welding. Background Technique

[0002] Pipes are materials used for making pipe fittings. Different pipe fittings require different pipes. The quality of the pipes directly determines the quality of the pipe fittings. Such pipes are widely used in construction projects, power plants, chemical plants, etc. When installing and connecting metal pipes, it is necessary to align and weld two sections of metal pipes, so a pipe fixing device is required. In the field of pipe welding, especially in occasions where high-precision welding is required, the fixing and positioning of pipes are crucial for welding quality.

[0003] Traditional fixing devices often adopt a single fixing method, such as rigid support or simple clamps. This fixing method is difficult to adapt to pipes of different diameters and shapes. When the diameter of the pipe changes, the fixing device cannot provide sufficient supporting force and stability, resulting in the pipe being prone to displacement or shaking during the welding process. Moreover, traditional fixing devices lack the function of adjusting the clamping force. The non-adjustable clamping force limits the adaptability of the fixing device to different pipes. Therefore, the utility model proposes a fixing device for pipe welding. Content of the Utility Model

When the diameter of the pipe changes, the fixing device cannot provide sufficient supporting force and stability, resulting in the pipe being prone to displacement or shaking during the welding process. Moreover, traditional fixing devices lack the function of adjusting the clamping force. The non-adjustable clamping force limits the adaptability of the fixing device to different pipes.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0023] The following will be described in conjunction with the preferred embodiments of the device of the present utility model.

[0024] Please refer to Figures 1-4 As shown, the fixing device for pipe welding includes a workbench 1. A through hole 101 is correspondingly opened at the top end of the workbench 1. A fixed clamping mechanism 3 is correspondingly arranged on the upper surface of the workbench 1 above the through hole 101. Below the bottom of the workbench 1, a debugging mechanism 5 is arranged below the fixed clamping mechanism 3;

[0025] Among them, the fixed clamping mechanism 3 includes a base 301, a lower fixing plate 302, a fixing rod 303, a fixing sleeve 304, a nut 305, a threaded hole 306, a lead screw 307, a knob cap 308 and an upper fixing plate 309. The base 301 is slidably arranged on the upper surface of the workbench 1. Lower fixing plates 302 are provided on the left and right sides of the top of the base 301. And on the upper surface of the base 301, and corresponding fixing rods 303 are provided between the two lower fixing plates 302 on both sides. The fixing rods 303 serve as the lifting guides for the upper fixing plate 309. The top of the fixing rod 303 is fixedly sleeved with a fixing sleeve 304 through a nut 305. A threaded hole 306 is opened in the center of the fixing sleeve 304. A lead screw 307 is threadedly connected to the threaded hole 306. And the top end of the lead screw 307 extends above the fixing sleeve 304 and is fixedly connected with a knob cap 308. The bottom end of the lead screw 307 is fixedly connected with an upper fixing plate 309.

[0026] Furthermore, a first pipe 9 and a second pipe 10 are respectively inserted between the upper fixing plates 309 and the lower fixing plates 302 on both sides.

[0027] Furthermore, the openings on the sides of the upper fixing plate 309 and the lower fixing plate 302 close to the pipes are V-shaped, which is convenient for pipes of different diameters to be inserted and fixed, and effectively prevents the pipes from sliding or rolling during the clamping process.

[0028] Furthermore, Teflon coatings are applied to the inner sides of the lower fixing plate 302 and the upper fixing plate 309. The Teflon coatings applied to the inner sides of the lower fixing plate 302 and the upper fixing plate 309 have excellent wear resistance and corrosion resistance, and can prevent the pipes from being damaged during the fixing process.

[0029] Specifically, when it is necessary to place the pipe into the clamping mechanism, first adjust the position of the base 301 on the workbench 1 so that it is aligned with the pipe to be welded. Place the pipe on the lower fixing plate 302 and ensure that the axis of the pipe is perpendicular to the fixing rod 303. Then rotate the knob cap 308. Through the threaded connection between the lead screw 307 and the threaded hole 306, the upper fixing plate 309 moves up and down along the fixing rod 303. As the upper fixing plate 309 descends, the distance between it and the lower fixing plate 302 gradually decreases, thereby clamping the pipe. By continuously rotating the knob cap 308, the clamping force can be precisely adjusted to ensure that the pipe remains stable during the welding process. When the clamping force reaches an appropriate level, stop rotating the knob cap 308. At this time, the upper fixing plate 309 and the lower fixing plate 302 jointly form a stable clamping of the pipe. Since the sides of the upper fixing plate 309 and the lower fixing plate 302 close to the pipe are designed to be V-shaped, it can adapt to pipes of different diameters and effectively prevent the pipes from sliding or rolling during the clamping process. And the application of the Teflon coating further ensures that the pipes will not be damaged during the clamping process.

[0030] Furthermore, the debugging mechanism 5 includes a mounting plate 501, a driving motor 502, a bidirectional threaded rod 503, and threaded blocks 504. The mounting plate 501 is vertically arranged on both sides of the bottom of the workbench 1. A driving motor 502 is fixedly installed on one side of the mounting plate 501, and the output end of the driving motor 502 penetrates through the mounting plate 501 and is rotationally connected to the bidirectional threaded rod 503. When rotating, the threaded blocks 504 on both sides will move in opposite directions to achieve the horizontal adjustment of the clamping mechanism. Threaded blocks 504 are correspondingly threadedly connected to the outside of the bidirectional threaded rod 503.

[0031] Furthermore, a connecting block 4 is fixedly connected to the bottom of the base 301, and the connecting block 4 is fixedly connected to the top of the threaded block 504 through the through hole 101.

[0032] Specifically, start the driving motor 502. By rotating the bidirectional threaded rod 503, the threaded blocks 504 on both sides will move relatively in opposite directions, thereby driving the horizontal adjustment between the fixed clamping mechanisms 3 through the connecting block 4.

[0033] Furthermore, an installation frame 2 is arranged below the workbench 1. Bearing plates 6 are provided at the four corners of the bottom of the installation frame 2. The bearing plates 6 provide installation positions for the moving wheels 8 and the supporting members 7. Moving wheels 8 are arranged at the bottom of the bearing plates 6, and supporting members 7 are arranged beside the moving wheels 8. The supporting members 7 provide support during the operation of the device to prevent the device from moving due to the sliding of the moving wheels 8.

[0034] Working principle: First, insert the first pipe 9 and the second pipe 10 into the fixed clamping mechanisms 3 on both sides respectively. Then rotate the knob cap 308 to make the upper fixing plate 309 move downward along the fixed rod 303. Thus, through the descent of the upper fixing plate 309, it cooperates with the lower fixing plate 302 to clamp the pipe. Then, use the debugging mechanism 5 to move the fixed clamping mechanism 3 horizontally, so as to accurately butt the two sections of pipes, and then carry out the welding work of the pipes.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
