Description

Technical Field

[0001] This application relates to the field of welding equipment technology, specifically to an automatic welding device for water distribution pipes. Background Technology

[0002] Water distribution pipes consist of main pipes and branch pipes. Multiple branch pipes are installed on a single main pipe to divert the medium in the main pipe to different directions or different equipment. Water distribution pipes are widely used in heating systems, industrial or air conditioning water systems.

[0003] In the current technology, when connecting branch pipes to main pipes, manual welding or equipment welding is mostly used to connect the branch pipes to the main pipes. Branch pipes include square pipes and round pipes. However, most of the welding equipment in the current technology can only clamp and position round pipes. When welding square branch pipes, it is necessary to change to a different clamp to clamp the square branch pipes. That is, square branch pipes and round branch pipes require two different clamps. Since most of the existing clamps are fixedly connected to the welding equipment, the welding of square branch pipes and round branch pipes often requires different welding equipment, which increases welding costs and equipment space occupation.

[0004] Therefore, the existing automatic welding equipment for water distribution pipes has room for further improvement. Utility Model Content

[0005] In view of this, and in response to the technical problem that a single welding device in the prior art cannot weld both square and round water distribution pipes, this application provides an automatic welding device for water distribution pipes, whose clamps can simultaneously hold both square and round water distribution pipes, thereby enabling automatic welding of both types of water distribution pipes.

[0006] This application provides an automatic welding device for water distribution pipes, comprising: Mounting base; A welding torch is used to weld branch pipes to main pipes. A clamp, at least two, arranged at intervals along the same horizontal direction, is used to clamp a main pipe; it includes an L-shaped base and a clamping plate, the base and the clamping plate forming a clamping space; The clamping plate is provided with an L-shaped clamping part for clamping square and round main pipes.

[0007] Compared with existing technologies, the automatic welding equipment for water distribution pipes in this application can automatically weld main pipes and branch pipes. It includes multiple clamps spaced apart along the same horizontal direction to clamp the same main pipe. The welding torch can move along the arrangement direction of the clamps, thus automatically welding multiple branch pipes to the same main pipe to complete the welding of the water distribution pipes. Specifically, in this application, the clamps include a base and a clamping plate, with the clamping plate and base forming a clamping space. The base is L-shaped, and the clamping plate has an L-shaped clamping part. The L-shaped structure forms a clamping space. When clamping a square water pipe, the outer surface of the square water pipe makes surface contact with the L-shaped structure, thus achieving clamping of the square water pipe. When clamping a round water pipe, the outer surface of the round water pipe makes line contact with the L-shaped structure, thus achieving clamping of the round water pipe. Consequently, the automatic water pipe welding equipment of this application can simultaneously clamp both square and round water pipes, thereby improving the applicability of the welding equipment, reducing the number of welding equipment required for different types of water pipes, and reducing welding costs.

[0008] Preferred options also include: The mounting bracket is located on the mounting base, and its length extends parallel to the direction of the clamp arrangement. The displacement mechanism, mounted on the mounting bracket, is used to drive the welding torch to move in the horizontal and vertical planes.

[0009] In this embodiment, the mounting bracket is arranged along the clamp arrangement direction, and the displacement mechanism is arranged on the mounting bracket, so that the displacement mechanism can drive the welding torch to move along the clamp arrangement direction, so as to realize automatic welding at the connection between each branch pipe and the main pipe.

[0010] Preferably, the displacement mechanism includes: A horizontal displacement assembly, connected to a mounting bracket, is used to drive the welding torch to move horizontally. A vertical displacement component, connected to a horizontal displacement component, is used to drive the welding torch to move vertically. A rotary displacement assembly is used to connect the welding torch to the mounting base and to drive the welding torch to rotate in the horizontal plane.

[0011] In this embodiment, the horizontal displacement component, the vertical displacement component, and the rotational displacement component work together to achieve horizontal and vertical displacement of the welding torch, as well as rotation in the horizontal plane, thereby improving displacement flexibility and enabling the welding torch to be flexibly moved to the accurate position for welding, thus improving welding accuracy.

[0012] Preferred options also include: The first adjustment hole is located on the base, which penetrates the base horizontally, and its length extension direction is inclined to the horizontal plane. The first limiting member is provided on the clamping plate and is at least partially inserted into the first adjusting hole to achieve the connection between the clamping plate and the base; Wherein, the length of the first limiting member is less than the length of the first adjusting hole, and the first limiting member is slidably connected to the first adjusting hole.

[0013] In this embodiment, a first adjustment hole inclined to the horizontal plane is provided on the base, and a first limiting member is slidably disposed in the first adjustment hole, so that the clamping plate can slide along the first adjustment hole, thereby changing the distance between the L-shaped clamping part of the clamping plate and the base. That is, by changing the size of the clamping space, the clamping of pipes of different diameters can be realized, thereby improving the flexibility and applicability of the clamp.

[0014] Preferred options also include: A driving component is connected to the end of the clamping plate away from the clamping part, and is used to drive the clamping plate to move along the first adjustment hole; The driving direction of the driving component is parallel to the horizontal plane or parallel to the length extension direction of the first adjusting hole. And / or, The L-shaped clamping part has rounded corners at its ends, and the base has rounded corners at its ends.

[0015] In this embodiment, the driving component can provide support force to the clamping plate, so that the clamping plate is stable in a certain position to ensure the stability of the clamping plate, so that the clamp can stably clamp the main pipe to ensure the welding effect; at the same time, the driving component can drive the clamping plate to move along the length direction of the first adjustment hole to change the size of the clamping space to clamp main pipes of different diameters; and the ends of the L-shaped clamping part and the base are set with rounded corners instead of sharp corners, which can reduce damage to the outside of the circular water pipe.

[0016] Preferred options also include: The connector has one end connected to the drive component and the other end connected to the clamping plate. The second adjustment hole is provided on the connecting seat, and it passes through the connecting seat in the horizontal direction, with its length extending parallel to the vertical plane. The second limiting member is provided on the clamping plate and is at least partially inserted into the second adjusting hole; The length of the second limiting member is less than the length of the second adjusting hole, and the second limiting member is slidably connected to the second adjusting hole.

[0017] In this embodiment, by providing a second adjustment hole extending vertically on the connecting seat, when the clamping plate is driven to slide tilted along the first adjustment hole by the driving member, the connection position between the clamping plate and the driving member can also slide accordingly, thereby ensuring the synchronous displacement of the clamping plate, the base, and the driving member, and avoiding clamping.

[0018] Preferred options also include: The first mounting hole is provided on the clamping plate and is used to install the first limiting member; The second mounting hole is provided on the clamping plate and is distributed horizontally at intervals from the first mounting hole, and is used to install the second limiting member; Among them, the first adjustment hole, the second adjustment hole, the first mounting hole, and the second mounting hole are all waist-shaped structures; The first limiting member includes a first waist-shaped mounting portion that is adapted to the first adjusting hole and the first mounting hole; The second limiting member includes a second waist-shaped mounting portion that is adapted to the second adjusting hole and the second mounting hole.

[0019] In this embodiment, by setting the first adjustment hole, the second adjustment hole, the first mounting hole, and the second mounting hole as an oblong structure, the contact area between the first limiting member and the base and the contact area between the second limiting member and the connecting seat can be increased, thereby increasing the stability of the clamp displacement.

[0020] Preferred options also include: A connecting bracket is used to connect the welding torch to the mounting base; An adjustment device, located between the connecting bracket and the welding torch, is used for fine-tuning the horizontal direction of the welding torch.

[0021] In this embodiment, by setting an adjustment device, the horizontal direction of the welding torch can be finely adjusted to improve the accuracy of the welding position.

[0022] Preferably, the adjusting device includes: The housing has a movable cavity and a mounting port, with the mounting port communicating with the movable cavity; The movable block includes a limiting part and a connecting part, with the limiting part located inside the movable cavity; one end of the mounting part is connected to the limiting part, and the other end extends out of the mounting port and is connected to the welding gun; The outer diameter of the limiting part is R1, the inner diameter of the mounting part is R2, the inner diameter of the movable cavity is R3, and the inner diameter of the mounting port is R4, where R3>R1>R4>R2; Where (R3-R1)≥(R4-R2)=△R, △R=1~3mm.

[0023] In this embodiment, the limiting part cooperates with the movable cavity to ensure that the movable block and the shell are limited in the vertical direction; while there is a gap between the mounting part and the mounting port, and a gap between the movable cavity and the limiting part, so that the movable block can be displaced on the horizontal plane relative to the shell, thereby realizing the fine adjustment of the welding gun on the horizontal plane by 1~3mm.

[0024] Preferred options also include: An elastic element is located at the top of the limiting part and acts vertically between the housing and the limiting part; A rolling element, located at the bottom of the limiting part, acts vertically between the limiting part and the housing; The first mounting groove is located on the housing and is used to install the elastic element; The second mounting groove is located at the top of the limiting part and is used to install the elastic element; The third mounting slot, located on the housing, is used to mount rolling elements.

[0025] In this embodiment, the elastic element can apply a vertical clamping force to the movable block, so that the movable block can always maintain a tight fit with the rolling element, thereby reducing the displacement friction of the movable block in the horizontal direction and ensuring the smoothness and flexibility of the welding torch fine adjustment.

[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0029] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0030] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0031] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 6 illustrate.

[0032] This application provides an automatic welding equipment for branch pipes (hereinafter referred to as welding equipment), which is used to weld branch pipes onto main pipes and also has the function of clamping main pipes, which can ensure the stability of branch pipe welding.

[0033] Specifically, such as Figure 1 , Figure 2 As shown, the welding equipment includes a mounting bracket 4, a mounting base 1, a welding torch 3, a displacement mechanism, and a clamp 2. The mounting base 1 is a box structure. The mounting bracket 4 and the clamp 2 are both mounted on the platform of the mounting base 1. Multiple clamps 2 are provided and arranged at intervals along the same direction. Multiple clamps 2 are used to clamp the same main pipe to ensure the stability of the main pipe, and thus ensure the stability during welding. The mounting bracket 4 and the clamp 2 are arranged at intervals on the horizontal plane. The length extension direction of the mounting bracket 4 is the same as the arrangement direction of the clamp 2, and the length of the mounting bracket 4 is greater than the arrangement length of the clamp 2. The displacement mechanism is set on the mounting bracket 4 and is connected to the welding torch 3. The displacement mechanism can at least drive the welding torch 3 to move along the length direction of the mounting bracket 4 to realize the automatic welding of multiple branch pipes and the main pipe.

[0034] Among them, such as Figures 2 to 4As shown, the clamp 2 includes a clamping plate 22 and a base 21. The base 21 is fixed to the mounting base 1 by bolts or screws, etc. The mounting base 1 and the clamping plate 22 form a clamping space for clamping the main pipe. The base 21 has an L-shaped structure, which includes a baffle 213 and a bottom plate 211. The baffle 213 is vertically connected to the bottom plate 211, and the bottom plate 211 is set parallel to the horizontal plane. The bottom plate 211 is fixedly connected to the mounting base 1. The clamping plate 22 has an L-shaped clamping part 223 at one end near the base 21. The two L-shaped structures are opposite each other to form a clamping space. The base 21 and the clamping plate 22 respectively limit the diagonal direction of the main pipe. When clamping the square water pipe, two adjacent sides of the main pipe of the square water pipe make surface contact with the two limiting surfaces of the base 21, and the other two adjacent sides of the square water pipe make surface contact with the two limiting planes of the clamping part 223, thereby realizing the clamping of the main pipe of the square water pipe. Figure 3 As shown, when the main pipe of the circular water distribution pipe is clamped, the outer side of the main pipe of the circular water distribution pipe contacts the two vertical surfaces of the base 21 and the clamping part 223, thereby achieving clamping of the main pipe of the circular water distribution pipe; thus enabling the automatic water distribution pipe welding equipment of this application to simultaneously clamp both square and circular water distribution pipes, thereby improving the applicability of the welding equipment, reducing the number of welding equipment for different types of water distribution pipes, and reducing welding costs.

[0035] In this embodiment, as Figure 3 As shown, the two tips of the L-shaped clamping part 223 of the clamping plate 22 are rounded, and the tip of the base 21 is rounded, so that the tips of the base 21 and the clamping plate 22 facing the clamping space are smooth arc surfaces. When the tip is in contact with the main pipeline, it can reduce damage to the outside of the circular water distribution pipe.

[0036] Furthermore, the clamp 2 is described in more detail; the base 21 also includes wing plates 212, and two wing plates 212 extend from the side of the base plate 211 away from the baffle 213. The angle between the wing plates 212 and the base plate 211 is an obtuse angle. The wing plates 212 are provided with a first adjustment hole 214, which extends horizontally through the wing plates 212. The length of the first adjustment hole 214 extends in an inclined direction to the horizontal plane. The clamping plate 22 is at least partially located between the two wing plates 212. The clamping plate 22 is provided with a first limiting member 25, which protrudes horizontally from both sides of the clamping plate 22. At least part of the first limiting member 25 is located within the first adjustment hole 214 to achieve the connection between the clamping plate 22 and the base 21. The length of the first limiting member 25 is less than the length of the first adjustment hole 214. The first limiting member 25 is slidably connected to the first adjustment hole 214, thereby allowing the clamping plate 22 to slide along the first adjustment hole 214 to change the size of the clamping space.

[0037] The clamp 2 further includes a driving member 24. The driving end of the driving member 24 is connected to the end of the clamping plate 22 away from the clamping part 223. The driving member 24 is located on the side away from the baffle 213 of the base 21. The driving member 24 is used to drive the clamping plate 22 to move horizontally, thereby moving the clamping plate 22 along the length extension direction of the first adjustment hole 214. The driving direction of the driving member 24 is parallel to the horizontal plane or parallel to the length extension direction of the first adjustment hole 214. In this embodiment, the driving member 24 is set on the platform of the mounting base 1, and the driving direction of the driving member 24 is parallel to the horizontal plane. In this embodiment, the driving member 24 can provide support force to the clamping plate 22, so that the clamping plate 22 is stable in a certain position, thereby ensuring the stability of the clamping plate 22 and enabling the clamp 2 to stably clamp the main pipe, thus ensuring the welding effect. At the same time, the driving member 24 can drive the clamping plate 22 to move along the length direction of the first adjustment hole 214, thereby changing the size of the clamping space to clamp the main pipe of different diameters, thus improving the applicability of the welding equipment.

[0038] The clamping plate 22 is provided with a first mounting hole 221, which is used to install a first limiting member 25. The first limiting member 25 passes through the first mounting hole 221 and is inserted into the first adjusting hole 214. In order to ensure the installation stability of the first limiting member 25 and the clamping plate 22, the outer wall surface of the first limiting member 25 is tightly fitted with the inner wall surface of the first mounting hole 221.

[0039] In this embodiment, the driving component 24 is a linear drive component, which can be a linear drive motor or a linear drive hydraulic cylinder.

[0040] Furthermore, such as Figures 3 to 4As shown, the clamp 2 also includes a connecting seat 23, which is disposed between the driving member 24 and the clamping plate 22. One end of the connecting seat 23 is connected to the driving member 24, and the other end is connected to the clamping plate 22. The connecting seat 23 is provided with a second adjusting hole 231, which extends horizontally through the connecting seat 23 and its length is parallel to the vertical plane. The clamping plate 22 also has a second limiting member 26, which protrudes horizontally from both sides of the clamping plate 22. The second limiting member 26 is at least partially inserted into the second adjusting hole 231 to achieve the connection between the clamping plate 22 and the connecting seat 23. The length of the second limiting member 26 is less than the length of the second adjusting hole 231, and the second limiting member 26 is slidably connected to the second adjusting hole 231. To achieve a sliding connection between the clamping plate 22 and the connecting seat 23; in this embodiment, the driving member 24 applies a horizontal driving force to the clamping plate 22. Under the action of the first adjusting hole 214, the horizontal driving force is decomposed, and the clamping plate 22 is displaced in both the vertical and horizontal directions. However, the first adjusting hole 214 simultaneously limits the clamping plate 22 in both the horizontal and vertical directions. The setting of the second adjusting hole 231 causes the clamping plate 22 to also be displaced in the vertical direction relative to the driving member 24, thereby offsetting the limitation of the first adjusting hole 214 on the clamping plate 22 in the vertical direction, ensuring the synchronous displacement of the clamping plate 22 with the base 21 and the driving member 24, making the clamping plate 22 slide more smoothly along the first adjusting hole 214, and avoiding jamming when the clamping plate 22 is displaced.

[0041] Among them, such as Figure 4 As shown, the clamping plate 22 includes a connecting block 224 and ear plates 225. Two ear plates 225 are provided, which are arranged in parallel and spaced apart. The connecting seat 23 is located between the two ear plates 225. One end of the connecting block 224 is connected to the clamping part 223, and the other end is connected to the ear plate 225. A first mounting hole 221 is provided at one end of the connecting block 224 near the ear plate 225. A second mounting hole 222 is provided on the ear plate 225 and penetrates the ear plate 225 in a horizontal direction. A second adjustment hole 231 is provided at the corresponding position of the connecting seat 23. A second limiting member 26 passes through the second mounting hole 222 and the second adjustment hole 231 to connect the clamping plate 22 to the connecting seat 23, while allowing the clamping plate 22 to slide relative to the connecting seat 23 along the second adjustment hole 231 through the second limiting member 26.

[0042] In this application, as Figure 4As shown, the first adjustment hole 214, the second adjustment hole 231, the first mounting hole 221, and the second mounting hole 222 are all waist-shaped structures. The first limiting member 25 includes a first limiting part and a first waist-shaped mounting part. The first waist-shaped mounting part has a waist-shaped structure, and its width is the same as the width of the first mounting hole 221 and the first adjustment hole 214. That is, the shape of the cross-section of the first limiting member 25 is consistent with the shape of the first mounting hole 221, and the size is adapted to each other. This makes the first limiting member 25 a flat elongated structure. This setting can prevent the clamping plate 22 from shaking or rotating around the first limiting member 25, thereby ensuring the stability and reliability of clamping. There are two first limiting parts, which are circular plate structures, located at both ends of the first waist-shaped mounting part. The width of the first limiting part is greater than that of the first waist-shaped mounting part, which is used to limit the displacement of the first waist-shaped mounting part in its length extension direction and prevent the first limiting member 25 from coming out of the first adjustment hole 214 and the first mounting hole 221.

[0043] Correspondingly, the second limiting member 26 includes a second limiting part and a second waist-shaped mounting part. The second waist-shaped mounting part has a waist-shaped structure, and its width is the same as the width of the second mounting hole 222 and the second adjusting hole 231. That is, the shape of the cross-section of the second limiting member 26 is consistent with the shape of the second mounting hole 222, and the dimensions are compatible. This makes the second limiting member 26 a flat, elongated structure. This arrangement can prevent the clamping plate 22 from shaking or rotating around the second limiting member 26, thereby ensuring the stability and reliability of clamping. There are two second limiting parts, which are strip-shaped structures. The second limiting parts extend towards the driving member 24 to limit the displacement of the second waist-shaped mounting part in its length extension direction and prevent the second limiting member 26 from coming out of the second adjusting hole 231 and the second mounting hole 222.

[0044] Based on any of the above embodiments, the displacement mechanism will be further described; such as Figure 1 , Figure 2 , Figure 5 As shown, the displacement mechanism includes a horizontal displacement component 5, a vertical displacement component 6, and a rotary displacement component 7. The horizontal displacement component 5 is connected to the mounting bracket 4. The vertical displacement component 6 is connected to the drive end of the horizontal displacement component 5 via a connecting plate. The rotary displacement component 7 is connected to the drive end of the vertical displacement component 6 via a connecting bracket 8. The drive end of the rotary displacement component 7 is connected to the welding torch 3. This allows the horizontal displacement component 5 to simultaneously drive the vertical displacement component 6, the rotary displacement component 7, and the welding torch 3 to move linearly in the horizontal direction. The vertical displacement component 6 can simultaneously drive the rotary displacement component 7 and the welding torch 3 to move linearly in the vertical direction. The rotary displacement component 7 can drive the welding torch 3 to rotate on the horizontal plane, thereby improving the displacement flexibility of the welding torch 3 and enabling it to flexibly move to the accurate position for welding, thus improving welding accuracy.

[0045] In this embodiment, the horizontal displacement component 5 and the vertical displacement drive can be linear drive type electric actuators or cylinder-type components, and the rotary displacement component 7 can be rotary drive type cylinders or electric actuator-type components.

[0046] Based on any of the above embodiments, the welding equipment can be further expanded; such as... Figures 5 to 6 As shown, the welding equipment also includes a connecting bracket 8 and an adjusting device 9. One end of the connecting bracket 8 is connected to the vertical displacement component 6, and the other end is connected to the welding torch 3. The welding torch 3 includes a mounting shell, a positioning shaft 31, and a welding head 32. The mounting shell is sleeved on the positioning shaft 31, which serves as the welding center. The welding head 32 is connected to the mounting shell 91 through a rotary displacement component 7, which can drive the welding head 32 to rotate around the center line of the positioning shaft 31.

[0047] Specifically, the adjusting device 9 operates between the connecting bracket 8 and the mounting shell. The adjusting device 9 is used to make micro-distance adjustments to the welding torch 3 in the horizontal direction. On the one hand, it can make fine adjustments between the welding torch 3 and the welding station to improve welding accuracy. On the other hand, when the position of the welding torch 3 is about to shift during the operation of the welding torch 3 and is misaligned with the welding position, the movable block 92 is moved by force to keep the welding torch 3 and the welding position fixed. The misalignment is offset by the relative movement of the movable block 92 and the shell 91.

[0048] like Figure 5 , Figure 6 As shown, the adjusting device 9 includes a housing 91 and a movable block 92. The top of the housing 91 is connected to the connecting device via bolts, screws, or other connecting parts. The housing 91 contains a movable cavity 911, and the bottom of the movable cavity 911 has a downward-facing mounting opening 912 that communicates with the movable cavity 911. The movable block 92 includes a limiting part 921 and a connecting part. The limiting part 921 is located within the movable cavity 911. The top of the mounting part 922 is connected to the limiting part 921, and the bottom of the mounting part 922 extends out of the mounting opening 912 and is detachably connected to the mounting housing via bolts or screws. The outer diameter of the limiting part 921 is R1, the inner diameter of the mounting part 922 is R2, and the movable cavity 911... The inner diameter of 11 is R3, and the inner diameter of the mounting port 912 is R4. R3>R1>R4>R2, and (R3-R1)≥(R4-R2)=△R, △R=1~3mm. In this embodiment, the limiting part 921 cooperates with the movable cavity 911, and the outer diameter of the limiting part 921 is larger than the outer diameter of the mounting port 912, which can ensure the vertical limiting of the movable block 92 and the housing 91. There is a gap between the mounting part 922 and the mounting port 912, and there is a gap between the movable cavity 911 and the limiting part 921 on the horizontal plane, so that the movable block 92 can be displaced on the horizontal plane relative to the housing 91, thereby realizing the fine adjustment of the welding gun 3 on the horizontal plane by 1~3mm.

[0049] Preferably, △R=2mm, meaning that the welding torch 3 can achieve a fine adjustment of 2mm on the horizontal plane.

[0050] Furthermore, such as Figure 6 As shown, the adjusting device 9 also includes an elastic element 93 and a rolling element 94. In this embodiment, the elastic element 93 is a spring and the rolling element 94 is a steel ball. In this embodiment, there are at least three rolling elements 94 and at least one elastic element 93. The elastic element 93 is located at the top of the limiting part 921 and acts vertically between the housing 91 and the limiting part 921. The elastic element 93 provides the movable block 92 with a force that always points towards the welding gun 3. The rolling element 94 is located at the bottom of the limiting part 921 and acts vertically between the limiting part 921 and the housing 91. In this embodiment, twelve rolling elements 94 are provided and are evenly distributed around the center of the movable block 92. The tops of the rolling elements 94 are located on the same horizontal plane, so that the movable block 92 can receive uniform support force during movement, reducing the frictional resistance of the movable block 92 during movement, improving the smoothness and flexibility of the movement of the movable block 92. At the same time, this evenly distributed design can also better disperse the external force on the movable block 92 and extend the service life of the movable block 92 and the rolling elements 94. The twelve elastic elements 93 are provided and are evenly distributed around the center of the movable block 92, providing the movable block 92 with an all-round and stable elastic force.

[0051] In this embodiment, the rolling element 94 can also be replaced by a component with a hemispherical top surface or a component with an arc-shaped top surface. The rolling element 94 is used to provide support for the movable block 92. Using a spherical shape can reduce the contact area with the movable block 92, making the movement of the movable block 92 smoother. The rolling element 94 can also move, and the movement is even smoother. The three rolling elements 94 are in close contact with the movable block 92, and the three points form a surface, so that the movable block 92 is equivalent to sliding on a plane, which provides good support stability for the movable block 92. The elastic element 93 is used to provide clamping force for the movable block 92, so that the contact between the movable block 92 and the rolling element 94 is reliable. Through the cooperation of the rolling element 94 and the elastic element 93, the movable block 92 can move freely and is subject to appropriate pressure constraint to ensure the stability and adjustment accuracy of the welding torch 3 during use.

[0052] like Figure 6As shown, the housing 91 is provided with a first mounting groove that mates with the elastic element 93, and the top of the limiting part 921 is provided with a second mounting groove that mates with the first mounting groove. The two ends of the elastic element 93 are respectively located on the first mounting groove and the second mounting groove. The cooperation of the first mounting groove and the second mounting groove not only provides a mounting position for the elastic element 93, but also effectively prevents the elastic element 93 from shifting or falling off during operation, ensuring the reliable operation of the elastic element 93. After the two ends of the elastic element 93 are bound by the first mounting groove and the second mounting groove, the movable block 92 slides horizontally during operation, and the upper and lower ends of the elastic element 93 shift. After the operation is completed, the elastic element 93 automatically resets, and the movable block 92 automatically returns to its position. During the operation of the welding torch 3, the twelve elastic elements 93 can work together, and are compressed or stretched accordingly according to the moving direction and distance of the movable block 92, thereby adjusting the magnitude and direction of the elastic force on the movable block 92 in real time, further ensuring the smooth movement of the movable block 92 and the precision of the welding torch 3 adjustment.

[0053] To ensure reliable installation of the elastic element 93, both the first and second mounting grooves are circular grooves, and the diameters of both grooves match the outer diameter of the elastic element 93. During installation, the elastic element 93 fits snugly against the inner walls of the first and second mounting grooves, preventing it from wobbling or shifting unnecessarily within the grooves, thus improving the stability of the installation. The circular groove design also facilitates manufacturing, reducing production costs and increasing production efficiency.

[0054] To ensure reliable installation of the rolling element 94, the movable cavity 911 is provided with a third mounting groove that mates with the rolling element 94. The rolling element 94 is located in the third mounting groove, with its top outside the groove. The design of the third mounting groove allows for positioning and fixing of the rolling element 94, facilitating its installation. It also limits the movement of the rolling element 94, ensuring its position within the movable cavity 911.

[0055] To ensure reliable movement of the movable block 92, the rolling elements 94 are evenly distributed around the center of the movable block 92, and the maximum distance between the two third mounting slots is less than the diameter of the movable block 92. The even distribution of the rolling elements 94 around the center of the movable block 92 forms a stable support structure, ensuring that the movable block 92 experiences uniform force during movement and will not tilt. The diameter of the movable block 92 is greater than the maximum distance between the two opposing third mounting slots, and a distance is also maintained between the top of the rolling elements 94 and the wall of the third mounting slot. This ensures that the movable block 92 will not exceed the rolling elements 94 during small-range movements, guaranteeing the support of the rolling elements 94 for the movable block 92.
