Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a pipe welding fixture. Background Technology

[0002] In the existing welding technology field, tooling equipment for pipe welding is frequently used. For example, a welding tooling disclosed in the technical solution CN118081241A includes a mounting base, a support frame, a lifting component, and a support member. The mounting base is used to place the battery cell module assembly. The support frame includes a support portion, which is vertically spaced from the mounting base so that the battery cell module assembly is located between the support portion and the mounting base. A preset opening is provided on the support portion. The output portion of the lifting component passes through the mounting base and abuts against or connects to the battery cell module assembly to drive the battery cell module assembly on the mounting base to rise. A welding nozzle is provided on the support member, which is disposed on the support portion so that the welding nozzle is positioned above the part to be welded on the lifted battery cell module assembly through the preset opening, and is in contact with or has a gap from the part to be welded. Using the welding tooling of this application makes the welding operation of welding aluminum or copper busbars to the electrodes of the battery cell more convenient.

[0003] However, in actual work, there are some pipe structures that do not directly weld two pipes together when welding. Some pipes need to have welding holes processed at the side wall of the end, and then the smaller pipe body is welded into the welding hole. This structure can usually be used in some heat exchangers, and this type of pipe welding device is more difficult to weld.

[0004] The main problem is fixing the welded pipe. The welded pipe needs to be fixed in the welding hole to achieve a good welding result. However, due to the large number of welding holes and their special positions, it is very troublesome and difficult to weld this type of pipe. The welding efficiency and welding quality are poor and do not meet the current technical requirements.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a pipe welding fixture with a reasonable structure that can effectively improve welding quality and efficiency. Summary of the Invention

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a pipe welding fixture; the technical solution is as follows:

[0007] A pipe welding fixture includes a fixed base. A first groove is provided on the left side of the fixed base, and two lead screw sliders are embedded in the first groove. A clamping mechanism is correspondingly connected to the upper end of the two lead screw sliders. The clamping mechanism is located on the upper left side of the fixed base. The two lead screw sliders can respectively drive the two clamping mechanisms to move left and right on the fixed base. A lead screw motor is also installed on the fixed base. The lead screw shaft of the motor extends laterally into the first groove and passes through the two lead screw sliders. When the lead screw motor drives the lead screw shaft to rotate, the two lead screw sliders embedded in the first groove can correspondingly drive the clamping mechanisms above to move.

[0008] Furthermore, a vertical partition is installed in the middle of the first chute, and the lead screw shaft passes through the vertical partition. The threads on the lead screw shafts on both sides of the vertical partition are arranged in opposite directions. When the lead screw motor rotates and drives the lead screw shaft to rotate, the lead screw sliders on both sides move inward or outward simultaneously. The two clamping mechanisms are installed inside the pipe to be welded, and the pipe is clamped and fixed from the inside by the clamping mechanisms on both sides.

[0009] Furthermore, a welding hole is provided on one side of the pipe, and a second sliding groove is provided on the right side of the fixed base. A movable slider is installed in the second sliding groove, and a support rod is installed on the movable slider. An auxiliary plate is installed on the support rod, and an auxiliary hole is provided on the auxiliary plate that corresponds to the position of the welding hole on the pipe. The height of the auxiliary hole is the same as the height of the welding hole. The welding pipe extends laterally from the auxiliary hole and then extends into the welding hole, and then is welded by welding equipment.

[0010] Furthermore, the support rod is configured as a telescopic rod structure with adjustable height; by setting the height-adjustable support rod, the height of the auxiliary plate can be adjusted accordingly to correspond to the welding holes on the pipes of different heights.

[0011] Furthermore, the pipe is configured as a circular or square pipe structure; this device can be used not only for circular pipes but also for square pipes, and the position of the clamping mechanism and the position of the auxiliary plate are set according to the shape and structure of the pipe.

[0012] Furthermore, a tightening rod is installed on the tightening mechanism, and a tightening block is installed at the end of the tightening rod. The tightening mechanisms on both sides move inward or outward simultaneously under the action of the lead screw and slider. The tightening mechanisms on both sides move synchronously, and the tightening blocks on both sides simultaneously tighten outward or retract inward.

[0013] Furthermore, a tightening pad is provided at the end of the tightening block; the tightening pad can conveniently protect the lower end of the pipe, resulting in a reasonable structure.

[0014] Furthermore, a bearing is provided at the outer end of the movable slider, and a threaded rod is correspondingly installed on the bearing. The threaded rod passes backward through the second sliding groove, and a handle is installed at the end of the rod.

[0015] Beneficial effects: This utility model has the following beneficial effects:

[0016] 1) This device adjusts the position of the two top mechanisms so that the pipe can be lowered to fit the two clamping mechanisms inside. After the pipe is lowered to fit the two clamping mechanisms, the two clamping mechanisms are opened simultaneously so that the two clamping mechanisms can move to both sides at the same time. Thus, the clamping blocks clamp and fix the pipe on both sides from the inside. The whole device can fix the pipe, has a reasonable structure, and is easy to use.

[0017] 2) The position of the clamping mechanism in this device is adjustable. The top clamping mechanism is connected to a lead screw slider, which is embedded in the first slide groove. A lead screw motor and a lead screw shaft are installed at the corresponding position of the first slide groove. A vertical partition is set in the middle of the first slide groove to separate the positions of the two lead screw sliders and also to limit their movement. More importantly, the lead screw threads on both sides of the lead screw shaft are reversed using the vertical partition as the dividing point. When the lead screw shaft rotates, the lead screw sliders on both sides can move inward or outward simultaneously. The lead screw motor can then drive the clamping mechanism on both sides to move inward or outward simultaneously, thus adjusting the position of the clamping mechanism. The clamping motor is then used to fix the pipe. The structure is ingeniously and reasonably designed and easy to use.

[0018] 3) An auxiliary plate is also provided on the right side of this device. The auxiliary holes on the auxiliary plate correspond to the welding holes on the pipe. Therefore, during welding, the auxiliary holes can be aligned with the welding holes, and the welding pipe can be inserted into the auxiliary holes and then extended into the welding holes. At this time, the position of the welding holes is fixed, and welding can be performed by welding equipment. This can achieve the welding fixation of the welding holes opened at the upper end of the pipe and the pipe body. The structure is ingenious and easy to use.

[0019] 4) The height of the support rod in this device is adjustable, so it can be adjusted according to the height of the welding hole at the upper end of the pipe to make the welding hole correspond to the auxiliary hole. Secondly, the support rod is mounted on the movable slider, which is embedded in the second slide groove. The movable slider can move back and forth in the second slide groove under the action of the threaded rod at the rear, thereby adjusting the position of the movable slider in the second slide groove. Then, the position of the auxiliary plate above can be adjusted according to the length of the welded pipe to be welded, which can adapt to welded parts of different lengths and heights. The overall structure is very reasonable and easy to use, and it is suitable for structures with welding holes at the upper end of pipes. Attached Figure Description

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pipe welding fixture includes a fixed base 1. A first groove 101 is provided on the left side of the fixed base 1. Two lead screw sliders 2 are embedded in the first groove 101. The upper ends of the two lead screw sliders 2 are connected to and installed with a clamping mechanism 3. The clamping mechanism 3 is located on the upper left side of the fixed base 1. The two lead screw sliders 2 can drive the two clamping mechanisms 3 to move left and right on the fixed base 1 respectively. A lead screw motor 4 is also installed on the fixed base 1. The lead screw shaft 5 of the lead screw motor 4 extends laterally into the first groove 101 and passes through the two lead screw sliders 2. When the lead screw motor 4 drives the lead screw shaft 5 to rotate, the two lead screw sliders 2 embedded in the first groove 101 can correspondingly drive the clamping mechanism 3 above to move.

[0026] Furthermore, a vertical partition 6 is installed in the middle of the first slide groove 101. The lead screw shaft 5 passes through the vertical partition 6, and the threads on the lead screw shafts 5 on both sides of the vertical partition 6 are set in opposite directions. When the lead screw motor 4 rotates and drives the lead screw shaft 5 to rotate, the lead screw sliders 2 on both sides move inward or outward at the same time, and the two clamping mechanisms 3 are installed inside the end of the pipe 7 to be welded. The pipe 7 is clamped and fixed from the inside by the clamping mechanisms 3 on both sides.

[0027] A welding hole 8 is provided on one side of the pipe 7, and a second slide groove 102 is provided on the right side of the fixed base 1. A movable slider 10 is installed in the second slide groove 102, and a support rod 11 is installed on the movable slider 10. An auxiliary plate 12 is installed on the support rod 11. An auxiliary hole 13 is provided on the auxiliary plate 12, which corresponds to the position of the welding hole 8 on the pipe 7. The height of the auxiliary hole 13 is the same as the height of the welding hole 8. The welding pipe 14 extends laterally from the auxiliary hole 13 and then extends into the welding hole 8, and then is welded by the welding equipment.

[0028] The support rod 11 is a telescopic rod structure with adjustable height; the tube 7 is a circular or square tube structure.

[0029] A clamping rod 15 is installed on the clamping mechanism 3, and a clamping block 16 is installed at the end of the clamping rod 15. The clamping mechanisms 3 on both sides move inward or outward simultaneously under the action of the screw slider 2. The clamping mechanisms 3 on both sides move synchronously, and the clamping blocks 16 on both sides clamp outward or retract inward simultaneously.

[0030] The end of the clamping block 16 is also provided with a clamping pad 17.

[0031] A bearing 18 is also provided at the outer end of the movable slider 10. A threaded rod 19 is installed on the bearing 18. The threaded rod 19 passes through the second slide groove 102 and a handle 9 is installed at the end of the rod.

[0032] The specific working principle of this device is as follows: First, the positions of the two top-mounted mechanisms are adjusted so that the pipe can be lowered to fit the two clamping mechanisms inside. After the pipe is lowered to fit the two clamping mechanisms, the two clamping mechanisms are opened simultaneously, so that the two clamping mechanisms can move to both sides at the same time. Thus, the clamping blocks clamp and fix the pipe on both sides from the inside. The whole device can fix the pipe, with a reasonable structure and convenient use.

[0033] Furthermore, in the above process, the position of the clamping mechanism is adjustable. The top clamping mechanism is connected to a lead screw slider, which is embedded in the first slide groove. A lead screw motor and a lead screw shaft are installed at the corresponding position of the first slide groove. A vertical partition is set in the middle of the first slide groove to separate the positions of the two lead screw sliders, which also serves as a limit. More importantly, with the vertical partition as the dividing point, the lead screw threads on both sides of the lead screw shaft are set to be opposite. So when the lead screw shaft rotates, the lead screw sliders on both sides can move inward or outward simultaneously. Then, the clamping mechanism on both sides can be driven by the lead screw motor to move inward or outward simultaneously, which can realize the position adjustment of the clamping mechanism. Then, the clamping motor is used to fix the pipe. The structure is ingenious and reasonable, and easy to use.

[0034] An auxiliary plate is also provided on the right side of this device. The auxiliary holes on the auxiliary plate correspond to the welding holes on the pipe. Therefore, during welding, the auxiliary holes are aligned with the welding holes, and the welding pipe is inserted into the auxiliary holes and then extended into the welding holes. At this time, the position of the welding holes is fixed, and welding can be performed using welding equipment. This device can achieve welding and fixing of the welding holes opened at the upper end of the pipe to the pipe body. The structure is ingenious and easy to use.

[0035] Furthermore, the height of the support rod in this device is adjustable, allowing it to be adjusted according to the height of the welding hole at the upper end of the pipe, ensuring that the welding hole corresponds to the auxiliary hole. Secondly, the support rod is mounted on a movable slider, which is embedded in the second slide groove. The movable slider can move back and forth within the second slide groove under the action of the threaded rod at the rear, thereby adjusting its position within the groove. This allows adjustment of the position of the upper auxiliary plate, which can be adjusted according to the length of the pipe to be welded, accommodating weldments of different lengths and heights. The overall structure is very reasonable and convenient to use, making it suitable for structures with welding holes at the upper end of pipes.

All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
