Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to an automatic welding anti-deformation positioning structure for the longitudinal seam of a high-voltage electrical switch housing. Background Technology

[0002] For example, patent publication number CN121373992B, entitled "A Positioning Structure for Welding a Car Body," includes a side abutment, a front abutment, a following frame, a positioning plate one, a positioning plate two, and a locking assembly. In this application, the following frame is locked to the car body panel by the clamping of the locking block. Therefore, during the pre-welding process, because the following frame is locked to the car body panel as one unit, and the pressing and bonding process ensures that the lining plate and the frame are tightly bonded, the welding quality is improved. Secondly, the positioning plate one and the positioning plate two guide the spot welding process, improving welding accuracy while simplifying welding steps and enhancing convenience. During the continuous welding process, the following frame is located in the middle position in the front-rear direction of the car body panel, providing a working reference and a positioning guide reference during continuous welding. In summary, during the welding process, it not only provides positioning and guiding functions, but also ensures that the lining plate and the frame are tightly bonded during spot welding, improving welding quality and enhancing overall work efficiency and convenience.

[0003] This application aims to solve the following technical problems existing in the above-mentioned applications: First, the existing welding equipment lacks a flexible angle adjustment mechanism, which makes it inconvenient to splice and fix shell parts, and makes it difficult to accurately control the splicing angle of the mating parts. Secondly, the high-temperature thermal stress during welding can easily cause deformation of thin-walled shells, resulting in larger weld gaps or misalignment. Furthermore, traditional welding torch positioning lacks real-time rigid constraints, which affects weld formation. Third, conventional follow-up support structures have significant sliding friction when moving along the weld, which increases the equipment load and easily scratches the surface of the precision housing. Furthermore, they have limited effect on suppressing the "wave deformation" common in thin plate welding.

[0004] Therefore, this application provides an automatic welding anti-deformation positioning structure for the longitudinal seam of a high-voltage electrical switch housing to meet the requirements. Summary of the Invention

[0005] The purpose of this application is to provide an automatic welding anti-deformation positioning structure for the longitudinal seam of a high-voltage electrical switch housing, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an automatic welding anti-deformation positioning structure for the longitudinal seam of a high-voltage electrical switch housing, comprising: Angle control mechanism; A positioning and clamping mechanism, comprising several such mechanisms arranged symmetrically in two rows above an angle control mechanism, wherein the angle control mechanism is configured to adjust the angular orientation of the positioning and clamping mechanisms, and wherein the positioning and clamping mechanisms are used to support and fix the welding angle of the housing; and A weld deformation control mechanism is located at the upper middle part of the angle control mechanism and is configured to provide positioning support and perform welding based on the part splicing corners defined by the positioning and clamping mechanism.

[0007] The angle control mechanism includes a support frame, and control turntables are provided on both sides of the upper end of the support frame. A drive motor for driving the control turntable to rotate is provided on one side of one of the control turntables. A support plate is provided between the two control turntables, and a slide rail is provided at the upper center of the support plate.

[0008] The positioning and clamping mechanism includes a fixed frame, which is fixedly installed on the upper end of the support plate. A hydraulic rod is provided on one side of the fixed frame. A structural plate is rotatably installed on the upper end of the hydraulic rod, and a rotating block is provided on the lower end of the structural plate. The structural plate is rotatably connected to the fixed frame through the rotating block.

[0009] The structural plate has a load-bearing plate at one end, and two first electric telescopic rods are symmetrically arranged at the lower end of the load-bearing plate. A contact plate is rotatably installed at one end of each of the two first electric telescopic rods, and the contact plate is rotatably connected to the load-bearing plate by a hinge.

[0010] The contact plate is provided with an electromagnetic adsorption device in the middle, which is used to adsorb and fix the shell parts placed on the upper part of the contact plate.

[0011] The weld deformation control mechanism includes a drive base, which is slidably mounted on the upper end of a slide rail, and a welding torch is provided on the upper end of the drive base. The upper end of the drive base is symmetrically provided with a second electric telescopic rod, and the upper end of each of the two second electric telescopic rods is provided with a mounting block. The two mounting blocks are rotatably mounted with two symmetrically arranged abutment plates inside, and the welding torch is located on the axis between the two abutment plates.

[0012] Both sides of the two mounting blocks are provided with side plates, and the upper end of each side plate is provided with several limiting holes. A frame is provided on one side of each of the two contact plates, and a connecting rod is provided on one side of the frame. The connecting rod is located inside the limiting hole, and a first spring is sleeved on the outer surface of the connecting rod. The first spring is configured to provide a counter-thrust force applied to the frame, which pushes the abutment plate against the corner of the housing part.

[0013] The two contact plates each have several square holes on their opposite surfaces. Two sliding blocks are slidably installed inside the frame. A spindle roller is rotatably installed between the two sliding blocks. The spindle roller is located inside the square holes. A second spring is provided on one side of each of the two sliding blocks. The second spring is configured to apply a thrust to cause the sliding block to drive the spindle roller to abut against the surface of the housing part.

[0014] The spindle roller is shaped like a spindle and is configured to abut against the surface of the housing part in a point contact or small area contact manner, and slide or rotate on the surface of the housing part.

[0015] The second electric telescopic rod is configured to move the mounting block and the contact plate up and down to finely adjust the distance between the welding gun and the weld. The drive base is configured to slide on the upper end of the slide rail to drive the welding torch and the contact plate to move along the weld direction.

[0016] In summary, the technical effects and advantages of this invention are as follows: 1. This invention drives the turntable to rotate via a drive motor, which in turn rotates the entire support plate and the upper component, adjusting it to an assembly angle that is easy for operators to operate. Then, a hydraulic rod drives the structural plate to rotate around the rotating block, achieving coarse adjustment of the angle of the shell parts. Then, the first electric telescopic rod drives the contact plate to fine adjust the angle around the hinge, and the electromagnetic adsorption device is used to fix it, ensuring extremely high precision in the splicing position of the two mating shell parts.

[0017] 2. In the welding process, the weld deformation control mechanism plays a crucial role in preventing deformation and providing precise guidance. The counter-force provided by the first spring is transmitted through the frame, pushing the contact plate to firmly abut against the corner of the shell part. The compression limit effectively prevents the gap between the parts from becoming too large or misaligned under welding thermal stress, ensuring the geometric stability of the weld. The sliding of the connecting rod in the limiting hole ensures the accuracy of the force direction, while the welding torch is located on the axis between the two contact plates, ensuring the absolute accuracy of the welding position and significantly improving the forming quality of the weld.

[0018] 3. In this invention, the second spring pushes the sliding block to drive the spindle roller to abut against the surface of the housing. The design of the spindle body shape makes it make point contact or small area contact with the housing. When the drive base moves along the slide rail, the spindle roller can slide with the mechanism and roll parallel to the surface of the housing, providing stable support force and effectively suppressing wave deformation during the welding process, thereby comprehensively improving the production efficiency and product qualification rate of longitudinal seam welding of high voltage electrical switch housing.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, Reference Figures 1 to 13 The above describes an automatic welding anti-deformation positioning structure for the longitudinal seam of a high-voltage electrical switch housing, which includes an angle control mechanism 1, a positioning clamping mechanism 2, and a weld deformation control mechanism 3.

[0024] Among them, several positioning and clamping mechanisms 2 are provided and are symmetrically distributed in two rows on the upper end of the angle control mechanism 1 to support and fix the welding angle of the shell. The weld deformation control mechanism 3 is located at the middle of the upper end of the angle control mechanism 1 and is configured to provide positioning support and perform welding operations based on the part splicing corners defined by the positioning clamping mechanism 2.

[0025] The drive motor 14 drives the control turntable 13 to rotate, which in turn drives the support plate 12 and the positioning clamping mechanism 2 and weld deformation control mechanism 3 above to rotate as a whole, adjusting to an angle that is convenient for workers to operate. Then, the housing parts are placed on the contact plate 23, and the hydraulic rod 27 is used to extend and retract to drive the structural plate 26 to rotate around the rotating block 28, so as to achieve the initial coarse adjustment of the part angle. Then, the first electric telescopic rod 24 drives the contact plate 23 to make fine adjustments around the hinge to precisely control the docking angle. Finally, the electromagnetic adsorption device 22 is energized to firmly adsorb and fix the parts.

[0026] During the welding stage, the corners of the mating parts are located between the two contact plates 34. The first spring 311 provides a counter-force, pushing the contact plates 34 to tightly press the corners of the parts, preventing welding thermal stress from causing excessive gaps or misalignment. The connecting rod 312 slides within the limiting hole 36 to ensure stable force direction. The welding torch 32 is always aligned with the axis between the two contact plates 34 for precise welding. The second electric telescopic rod 35 can move the contact plates 34 up and down to fine-tune the spacing of the welding torch 32.

[0027] Furthermore, when the contact plate 34 is in contact with the part, the second spring 315 pushes the sliding block 314 to drive the spindle roller 313 to closely contact the surface of the housing. The spindle shape of the spindle roller 313 makes it make point or small area contact with the part. When the drive base 31 moves along the slide rail 15 for welding, the spindle roller 313 can follow and roll parallel, thereby reducing friction while providing stable support and effectively suppressing welding deformation.

[0028] Example 2: This example provides a further technical solution for the angle control mechanism 1 and the positioning clamping mechanism 2.

[0029] Specifically, the angle control mechanism 1 includes a support frame 11, with control turntables 13 installed on both sides of the upper end of the support frame 11. One side of one of the control turntables 13 is equipped with a drive motor 14 for driving the control turntable 13 to rotate. A support plate 12 is provided between the two control turntables 13. A slide rail 15 is provided in the middle of the upper end of the support plate 12 to provide guidance for the sliding of the subsequent welding components.

[0030] Furthermore, the positioning and clamping mechanism 2 includes a fixed frame 21, which is fixedly installed on the upper end of the support plate 12. A hydraulic rod 27 is provided on one side of the fixed frame 21. A structural plate 26 is rotatably installed on the upper end of the hydraulic rod 27. A rotating block 28 is provided on the lower end of the structural plate 26, and a rotating connection is formed between the structural plate 26 and the fixed frame 21 through the rotating block 28. A load-bearing plate 25 is connected to one end of the structural plate 26. Two first electric telescopic rods 24 are symmetrically installed on the lower end of the load-bearing plate 25. A contact plate 23 is rotatably installed on one end of each of the two first electric telescopic rods 24. The contact plate 23 is rotatably connected to the load-bearing plate 25 through a hinge. An electromagnetic adsorption device 22 is provided in the middle of the contact plate 23, which is used to adsorb and fix the shell parts after being energized to ensure stability during the welding process.

[0031] Before the welding operation, the control turntable 13 connected to it is driven by the drive motor 14 to rotate. Since the support plate 12 is connected between the two control turntables 13, the rotation of the control turntable 13 will drive the entire support plate 12 and the positioning clamping mechanism 2 and the weld deformation control mechanism 3 installed on its upper end to rotate.

[0032] The drive motor 14 operates to adjust the support plate 12 to a preset angle, such as a horizontal or slightly tilted position, which is convenient for the operator to assemble.

[0033] At this time, the operator places the high-voltage electrical switch housing parts to be welded onto the upper end of the contact plates 23 on both sides. The electromagnetic adsorption device 22 on the contact plate 23 is energized, generating magnetic force to initially adsorb and fix the metal housing parts on the contact plate, preventing the parts from sliding or shifting during subsequent angle adjustment.

[0034] After the shell parts are attached and fixed, the splicing and alignment stage begins. By controlling the extension and retraction of the hydraulic rod 27, the structural plate 26 is pushed or pulled. Since the structural plate 26 is rotatably connected to the fixed frame 21 through the rotating block 28 at the lower end, the movement of the hydraulic rod 27 will cause the structural plate 26 to swing around the axis of the rotating block 28. The swing of the structural plate 26 will then cause the load-bearing plate 25 and the contact plate 23 to rotate as a whole. Through the coordinated movement of the hydraulic rods 27 on both sides of the support plate 12, the spatial posture and relative angle of the two shell parts can be adjusted significantly to make them roughly aligned and meet the basic requirements of splicing.

[0035] Based on the above adjustments, in order to ensure the uniformity of the weld gap and the butt joint accuracy, the first electric telescopic rod 24 is activated. The telescopic action of the first electric telescopic rod 24 will push or pull the contact plate 23 to rotate around the hinge between it and the load-bearing plate 25, so that the included angle between the contact plate 23 and the load-bearing plate 25 can change slightly, thereby making fine-tuning of the angle of the shell parts attached to it. Through the dual mechanism of coarse adjustment and fine adjustment, the corner positions of the two butt joint shell parts can be precisely controlled to ensure the geometric accuracy of the weld.

[0036] Once the splicing angle of the shell parts is precisely adjusted, the weld deformation control mechanism 3 begins to function to prevent welding thermal deformation. The drive base 31, which is set on the slide rail 15 in the middle of the support plate 12, moves to the welding start position. The first spring 311 continuously provides a counter-force, pushing the frame 39 to expand outward, so that the two symmetrically arranged abutment plates 34 tightly abut against the two sides of the splicing corner of the shell parts. The lateral extrusion force can effectively limit the thermal expansion and contraction deformation of the parts under the high temperature of welding, and prevent the weld gap from becoming larger or misaligned during the welding process.

[0037] In this embodiment, the drive motor 14 drives the control turntable 13 to rotate, which can drive the entire support plate 12 and the upper component to rotate and adjust to an assembly angle that is easy for the operator to operate. Then, the hydraulic rod 27 drives the structural plate 26 to rotate around the rotating block 28 to achieve coarse adjustment of the angle of the shell parts. Then, the first electric telescopic rod 24 drives the contact plate 23 to fine adjust the angle around the hinge. With the adsorption and fixation of the electromagnetic adsorption device 22, the extremely high precision of the splicing position of the two docking shell parts is ensured.

[0038] Example 3 provides a further technical solution for the weld deformation control mechanism 3.

[0039] In addition, the weld deformation control mechanism 3 includes a drive base 31, which is slidably mounted on the upper end of the slide rail 15. A second electric telescopic rod 35 is symmetrically arranged on its upper end. An installation block 37 is installed on the upper end of each of the two second electric telescopic rods 35. A side plate 33 is connected to both sides of the two installation blocks 37. A number of limiting holes 36 are opened on the upper end of the side plate 33.

[0040] Two symmetrically arranged abutment plates 34 are rotatably mounted inside the two mounting blocks 37. Several square holes 38 are opened on the opposite surfaces of the abutment plates 34. A frame 39 is provided on one side of the abutment plates 34. Two sliding blocks 314 are slidably mounted inside the frame 39. A spindle roller 313 is rotatably mounted between the two sliding blocks 314. A second spring 315 is provided on one side of the sliding block 314.

[0041] A connecting rod 312 is provided on one side of the frame 39. The connecting rod 312 is located inside the limiting hole 36, and a first spring 311 is sleeved on its outer surface to provide a counter-thrust force to push the contact plate 34 against the corner of the housing part.

[0042] The spindle roller 313 is located inside the square hole 38. The upper end of the drive base 31 is also equipped with a welding gun 32, which is located on the axis between the two contact plates 34 to ensure the accuracy of the welding position.

[0043] When the housing parts are initially fixed and angle adjusted by the positioning and clamping mechanism 2, the drive base 31 slides along the slide rail 15 at the upper end of the support plate 12, driving the entire weld deformation control mechanism to move to the predetermined welding start position. At this time, the welding corner between the two mating housing parts is exactly between the two symmetrically arranged abutment plates 34. Since the welding gun 32 is installed on the drive base 31 and its position is strictly set on the axis between the two abutment plates 34, it ensures that no matter how the mechanism moves, the welding gun 32 is always accurately aligned with the center trajectory of the weld.

[0044] Before welding begins, the first spring 311, which is sleeved on the outer surface of the connecting rod 312, is in a pre-compressed or naturally reset state. It continuously applies a counter-pushing force to the frame 39. This force is transmitted through the frame 39 and pushes the two abutment plates 34 to move inward, so that they are tightly pressed against the two sides of the splicing corner of the housing parts.

[0045] During this process, the connecting rod 312 slides within the limiting hole 36 opened in the side plate 33. The limiting hole 36 ensures that the connecting rod 312 can rotate freely within it or that the sliding position of the connecting rod 312 can be offset. This ensures that the direction of the counter-thrust force applied by the first spring 311 is always transmitted to the frame 39. The abutment plate 34 not only makes the corner positioning of the housing parts more accurate and eliminates assembly gap errors, but also effectively resists the thermal expansion stress caused by the high temperature of welding, preventing the gap between the parts from becoming abnormally large or misaligned during the welding process.

[0046] When the contact plate 34 is pressed against the surface of the part under the action of the spring force, the sliding block 314 installed inside the frame 39 slides under the pushing force of the second spring 315, which drives the spindle roller 313, which is rotated between the two sliding blocks 314, to extend out of the square hole 38, so that the spindle roller 313 protrudes from the square hole 38 and presses tightly against the surface of the housing part.

[0047] Because the spindle roller 313 is designed in the shape of a spindle, it forms point contact or a very small area of ​​line contact with the surface of the housing part. When the drive base 31 moves along the weld, the spindle roller 313 not only rotates between the sliding blocks 314, but also rolls parallel to the surface of the housing. The continuous thrust provided by the second spring 315 ensures the continuity of support, even if there are small flatness errors on the surface of the workpiece.

[0048] The second electric telescopic rod 35 extends and retracts, causing the mounting block 37 and the contact plate 34 to move up and down as a whole. This allows for fine adjustment of the height distance between the welding torch 32 and the weld, ensuring the stability of the welding heat input and the consistency of the weld formation.

[0049] As the drive base 31 slides smoothly on the slide rail 15, the welding torch 32 performs continuous automatic welding on the weld. Throughout this process, the contact plate 34 always applies rigid limit to both sides of the weld, and the spindle roller 313 provides follow-up rolling support. The two work together to effectively suppress angular deformation and wave deformation caused by welding stress, thereby ensuring high precision and high quality of longitudinal seam welding of high voltage electrical switch housing.

[0050] During the welding process, the weld deformation control mechanism 3 plays a crucial role in preventing deformation and providing precise guidance. The counter-force provided by the first spring 311 is transmitted through the frame 39, pushing the contact plate 34 to press tightly against the corner of the shell part. The compression limit effectively prevents the gap between the parts from becoming too large or misaligned under the welding thermal stress, ensuring the geometric stability of the weld. The sliding of the connecting rod 312 in the limiting hole 36 ensures the accuracy of the force direction. The welding torch 32 is located on the axis between the two contact plates 34, ensuring the absolute accuracy of the welding position and significantly improving the forming quality of the weld.

[0051] In addition, the second spring 315 pushes the sliding block 314 to drive the spindle roller 313 to abut against the surface of the housing. The design of the spindle shape makes it make point contact or small area contact with the housing. When the drive base 31 moves along the slide rail 15, the spindle roller 313 can slide with the mechanism and roll parallel to the surface of the housing, providing stable support force and effectively suppressing wave deformation during the welding process, thereby comprehensively improving the production efficiency and product qualification rate of longitudinal seam welding of high voltage electrical switch housing.

[0052] The working principle of this embodiment is as follows: When performing automatic welding of the longitudinal seam of the high-voltage electrical switch housing, the drive motor 14 first drives the control turntable 13 to rotate, which in turn drives the support plate 12 and the overall positioning and clamping mechanism 2 and weld deformation control mechanism 3 to rotate, adjusting to an angle that is convenient for workers to assemble the housing parts. Then, the housing parts are placed on the upper end of the contact plate 23, and the hydraulic rod 27 extends and retracts to drive the structural plate 26 to rotate around the rotating block 28, which in turn drives the load-bearing plate 25 and the contact plate 23 to rotate, thus achieving the initial adjustment of the angle of the housing parts. When fine-tuning is required, the first electric telescopic rod 24 extends and retracts, causing the contact plate 23 to rotate around the hinge, changing the angle between it and the load-bearing plate 25, thereby finely adjusting the angle of the two mating shell parts to ensure accurate positioning. At the same time, after the electromagnetic adsorption device 22 is powered on, it can firmly adsorb the shell parts onto the upper end of the contact plate 23.

[0053] Once the housing parts are fixed, the welding corners between the two mating parts are positioned between the two contact plates 34. During welding, the first spring 311 provides a counter-pushing force applied to the frame 39, pushing the contact plates 34 to abut against the corners of the housing parts. Through the squeezing action, the corners of the housing parts are positioned more accurately, and the gap between the parts is prevented from being too large.

[0054] The connecting rod 312 slides within the limiting hole 36 to ensure the stability of the direction of the reverse thrust. At the same time, the welding torch 32 is aligned with the axis position between the two contact plates 34 to weld, ensuring the accuracy of the weld. The second electric telescopic rod 35 can drive the mounting block 37 and the contact plate 34 to move up and down, thereby fine-tuning the distance between the welding torch 32 and the weld.

[0055] Furthermore, when the contact plate 34 contacts the surface of the part, the sliding block 314 slides inside the frame 39 under the thrust of the second spring 315, causing the spindle roller 313 to contact the surface of the housing part. Since the spindle roller 313 is spindle-shaped, it forms point contact or small area contact with the surface of the housing part. It can rotate between the sliding blocks 314 and slide parallel to the surface of the housing part when the drive base 31 slides on the slide rail 15, ensuring stable support and anti-deformation control of the housing part during the welding process.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
