DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0039] like Figures 1 to 3 As shown, a stainless steel water pipe welding device is provided in an embodiment of the present application. The device is mainly used as a welding auxiliary equipment for stainless steel pipes. When the stainless steel pipes are butt-jointed, the stainless steel pipes need to be accurately butt-jointed to facilitate the welding of the pipes.

[0040] In the docking process, specifically:

[0041] In order to achieve the above technical effects, the present application provides a variety of embodiments, wherein in the first embodiment, it is provided with:

[0042] A plurality of support frames 110 are provided, and the plurality of support frames 110 are all arranged in an arc shape, and the plurality of support frames 110 are combined with each other to form a support ring, and a support cavity 130 is formed on the support ring, and the support cavity 130 is used to support and fix the welded stainless steel pipe to facilitate the welding of the stainless steel pipe, wherein a plurality of abutment grooves 111 are annularly opened on the support frame 110, and two abutment grooves 111 are provided, and the two abutment grooves 111 are respectively arranged at two sides of the support frame 110, and the abutment grooves 111 are connected to the support cavity 130.

[0043] In the embodiment of the present application, the upper depth of the abutment groove 111 is less than half the thickness of the support frame 110, and an abutment member 120 is arranged in the abutment groove 111. The abutment member 120 is partially located in the abutment groove 111, and the shape of the abutment member 120 facing the abutment groove 111 matches the shape of the abutment groove 111, so that the abutment member 120 can be completely installed in the abutment groove 111, and the abutment member 120 performs linear movement back and forth in the abutment groove 111, so that the abutment member 120 can enter the support cavity 130 through the abutment groove 111.

[0044] In the above, one end of the abutment 120 toward the supporting cavity 130 is in a contracted state, so that when the abutment 120 moves in the abutment groove 111, the abutment 120 presents a contracted structure toward one side of the abutment groove 111. When the pipe is placed in the supporting cavity 130, one end of the abutment 120 toward the pipe is clamped between the inner wall of the supporting cavity 130 and the pipe, so that when the outer diameter of the pipe is smaller than the inner diameter of the supporting cavity 130, the abutment 120 can support the pipe, so that the support cavity 130 can support and fix pipes with different outer diameters.

[0045] In the present application, preferably, the width of the abutment member 120 in the abutment groove 111 in the direction from the support cavity 130 toward the outside of the support frame 110 gradually increases, so that the abutment member 120 can slowly abut against the pipeline.

[0046] In order to enable the abutment member 120 to effectively support the pipeline, the width of the widest part of the abutment member 120 is smaller than the width of the abutment groove 111 .

[0047] In the present application, the width of the abutting groove 111 is always the same on the supporting frame 110 .

[0048] Among them, in the above structure, in order to facilitate the movement of the abutment member 120 in the abutment groove 111, an inner wall and an outer wall are formed in the abutment groove 111, and the support cavity 130 is a circular structure as a whole. The inner wall and the outer wall in the abutment groove 111 are tangent to the support cavity 130, so that the abutment member 120 in the abutment groove 111 can smoothly enter the support cavity 130.

[0049] Preferably, in order to facilitate the movement of the abutting member 120 from the abutting groove 111 into the supporting cavity 130, the inner wall and the outer wall of the abutting groove 111 are both configured as arc-shaped structures, and both sides of the abutting member 120 are located in relative contact with the inner wall and the outer wall of the abutting groove 111, specifically:

[0050] A first abutting wall 121 and a second abutting wall 122 are provided on the abutting member 120. The first abutting wall 121 and the second abutting wall 122 are respectively provided on both sides of the abutting member 120, and the first abutting wall 121 always abuts against the inner wall of the abutting groove 111, and the second abutting wall 122 always abuts against the outer wall of the abutting groove 111, so that the abutting member 120 is stably installed in the abutting groove 111.

[0051] Since the above description states that the width of the abutment groove 111 is always the same on the support frame 110, and the width on the abutment member 120 gradually increases in the direction of the abutment groove 111 from the support cavity 130 toward the outside of the support frame 110, in order to avoid this structural conflict, a micro-elastic member is arranged inside the abutment member 120 in the present application, and the micro-elastic member abuts against the first abutment wall 121 and the second abutment wall 122 of the abutment member 120, so that when the abutment member 120 is placed in the abutment groove 111, the micro-elastic member always pushes the first abutment wall 121 to abut against the inner wall, and the micro-elastic member always pushes the second abutment wall 122 to abut against the outer wall, so that both sides of the abutment member 120 abut against the abutment groove 111.

[0052] The micro elastic member mentioned above is a micro spring, and a plurality of micro springs may be provided. The plurality of micro springs may be directly provided inside the abutting member 120 .

[0053] In the above description, both the first abutting wall 121 and the second abutting wall 122 are arc-shaped structures.

[0054] On the basis of the above structure, a driving device 300 is further provided, and the driving device 300 drives the abutting member 120 so that the abutting member 120 moves in the abutting groove 111 .

[0055] The driving device 300 is disposed on one side of the abutting member 120 , and is specifically installed on the supporting frame 110 , so that the driving device 300 can drive the abutting member 120 .

[0056] Specifically:

[0057] As shown in the figure, a driving roller 310 is provided at the output end of the driving device 300. The driving roller 310 is rotationally connected to the abutment member 120, and the driving roller 310 at the output end of the driving device 300 is tangent to the abutment groove 111. A docking portion 123 is provided at a position corresponding to the driving device 300 on the abutment member 120. The docking portion 123 is meshedly connected with the driving roller 310, so that the driving roller 310 drives the abutment member 120 to move in the abutment groove 111.

[0058] In the present application, the docking portion 123 is preferably a rack-shaped structure, and the driving roller 310 is a gear structure. When the gear is meshed with the rack, the driving roller 310 can drive the docking portion 123 to move, thereby driving the abutment member 120 to move in the abutment groove 111.

[0059] In the above structure, since the driving device 300 pushes the abutment member 120, a part of the abutment member 120 is located in the support cavity 130. When the pipeline is placed in the support cavity 130, the pipeline will be displaced in the support cavity 130 by the abutment action of the abutment member 120. In the embodiment of the present application, corresponding driving devices 300 are provided on both sides of the support frame 110. The two driving devices 300 drive the abutment member 120 at the same time, and the driving parameters of the two driving devices 300 are the same, so that the position of the pipeline in the support cavity 130 can always be kept relatively fixed during driving.

[0060] In the above description, the drive device 300 is arranged at one side of the inner wall or one side of the outer wall of the abutting member 120 to achieve the abutting driving effect on the abutting member 120 .

[0061] Among them, since abutment members 120 are provided on both sides of the support frame 110, in order to improve the abutment efficiency, a transmission shaft is also provided on the support frame 110. The transmission shaft passes through both sides of the support frame 110, and the transmission shaft is connected to the output end of the driving device 300, so that the driving device 300 can simultaneously drive the abutment members 120 on both sides through the transmission shaft.

[0062] Since the abutment members 120 on both sides need to be driven at the same time, when operated with a traditional transmission shaft, the abutment members 120 on both sides will rotate in the same direction, so that the abutment member 120 on one side moves toward the support cavity 130, and the abutment member 120 on the other side moves away from the support cavity 130. To avoid this situation, the transmission shaft in the embodiment of the present application is a coaxial reversal mechanism.

[0063] When the bearing on one side of the coaxial reversing mechanism rotates in the forward direction, the bearing on the other side rotates in the reverse direction, so that the abutting members 120 on both sides can abut and support the pipeline.

[0064] In order to effectively support the pipeline, a movable groove 140 is provided on the support frame 110. The movable groove 140 is arranged at a position corresponding to the abutment groove 111. Figure 2 shown.

[0065] The movable groove 140 is specifically arranged at one side of the abutting groove 111, more specifically at the outer wall of the abutting groove 111. The movable groove 140 is connected to the abutting groove 111. A movable part 141 and a movable plate 142 are arranged in the movable groove 140. The movable plate 142 is installed in the movable groove 140 through the movable part 141.

[0066] In the embodiment of the present application, the movable member 141 is a movable spring.

[0067] In the above description, since the movable plate 142 is arranged in the movable groove 140, an outer wall is formed on one side of the movable plate 142 toward the abutment groove 111. When the abutment member 120 moves in the abutment groove 111, the abutment member 120 pushes the movable member 141 to move toward the inner wall of the movable groove 140, so that the abutment member 120 can better and effectively support the pipeline.

[0068] In the above description, the movable groove 140 is disposed in the abutting groove 111 at one end thereof facing the supporting cavity 130 .

[0069] The support frame 110 is also provided with an opening 150, which is provided at one side of the support frame 110. Figure 1 As shown, the provision of the opening 150 can facilitate the welding of the pipeline by the welding device.

[0070] A second embodiment is also provided in the present application. Figure 4 As shown, specifically:

[0071] On the basis of the first embodiment, a support rod 200 and a support assembly 100 are further provided, wherein the support assembly 100 is composed of a plurality of support frames 110, and a plurality of support assemblies 100 are provided, and the plurality of support assemblies 100 all support and clamp the pipeline. For the convenience of description, in the present application, two support assemblies 100 are provided, and the two support assemblies 100 are connected by a support rod 200, so that support assemblies 100 are provided at both ends of the support rod 200, and a welding device 400 is sleeved on the support rod 200, and the welding device 400 slides on the support rod 200 along the setting direction of the support rod 200, so that the welding device 400 can weld the pipeline conveniently.

[0072] A third embodiment is also provided in the present application. Figure 5 As shown, specifically:

[0073] On the basis of the second embodiment, the abutting grooves 111 are correspondingly arranged on the two supporting assemblies 100 , and both ends of the abutting member 120 are respectively located in the abutting grooves 111 on the two supporting assemblies 100 .

[0074] By means of the abutment member 120, the pipeline can be abutted manually to a certain extent.

[0075] On the basis of the above embodiments, a welding method is provided in an embodiment of the present application, and the welding method comprises:

[0076] Step 1: Assemble multiple support frames 110 to form a support assembly 100, and place the pipe to be welded into the support cavity 130 on the support frame 110;

[0077] Step 2: Move the abutment member 120 in the abutment groove 111 by the driving device 300 so that the abutment member 120 supports the pipeline;

[0078] Step 3: Welding the pipeline using welding equipment 400.

[0079] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
