The device comprises a housing, wherein the inner wall of the housing is rotatably connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to a protective cover, and the upper surface of the housing is fixedly connected to a pressing component; a surrounding device can also make the roller roll against the outer surface of the special-shaped pipe while driving the roller to rotate in a circular motion.

Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle pipe welding, and in particular to a processing and welding device for special-shaped pipes of electric vehicles. Background Art

[0002] Electric vehicles, or electric-powered vehicles, use batteries as their energy source. Through the vehicle's controller, motor, and other components, they convert electrical energy into mechanical motion, controlling the current flow to change speed. Electric vehicles greatly facilitate transportation and play an indispensable role in daily use. Before production and assembly, electric vehicles require welding of some pipes, some of which are irregularly shaped. These irregularly shaped pipes are a general term for seamless steel pipes with cross-sectional shapes other than round.

[0003] During the welding process of special-shaped electric vehicle pipes, due to the special shapes of the pipes, when rotating welds of special-shaped elbows of different diameters, the center of the weld does not coincide with the center of the elbow joint, resulting in an incomplete weld seam at the joint during the welding process, further deteriorating the welding quality of the special-shaped electric vehicle pipes. Therefore, the present invention designs a special-shaped electric vehicle pipe welding device for processing elliptical special-shaped pipes to solve the above problem. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an electric vehicle special-shaped pipe processing and welding device, comprising a housing, an inner wall of the housing being rotatably connected to a rotating shaft, an outer surface of the rotating shaft being fixedly connected to a protective cover, and an upper surface of the housing being fixedly connected to a pressing component;

[0005] The processing and welding equipment also has:

[0006] The surrounding mechanism includes a fixed plate, a ring rail is fixedly connected to the side of the fixed plate away from the casing, the outer surface of the ring rail is rotatably connected to the surrounding device, the bottom of the surrounding device is fixedly connected to the telescopic rod, the end of the telescopic rod away from the surrounding device is fixedly connected to the connecting plate, the side of the connecting plate away from the telescopic rod is fixedly connected to the extrusion spring, and protective components are hinged at both ends of the connecting plate; the surrounding device rotates along the surface of the ring rail, and the slide rail is arranged in the middle of the casing, wherein the surrounding device rotates around the outer surface of the ring rail and drives the rotation of the telescopic rod and the connecting plate.

[0007] The rolling component includes an extrusion box. A welding gun is fixedly connected to the side of the extrusion box away from the connecting plate. A hose is fixedly connected to both sides of the extrusion box. The end of the hose away from the extrusion box is fixedly connected to a water tank. A water pipe is provided below the hose. The outer surface of the water pipe has water flow holes. The end of the water pipe away from the extrusion box is rotatably connected to a roller. The water pipe is made of a hard material.

[0008] Furthermore, the outer surface of the roller is provided with filter holes, the outer surface of the water pipe is fixedly connected to a limit plate, the side of the limit plate away from the roller is fixedly connected to an L-shaped plate, and the side of the L-shaped plate away from the limit plate is fixedly connected to a shield. The number of filter holes is relatively large.

[0009] Furthermore, the bottom end of the fixed plate is fixedly connected to the upper surface of the casing, the ring rail is arranged in the middle of the casing, the end of the extrusion spring away from the connecting plate is fixedly connected to the outer surface of the extrusion box, and the inner wall of the protective cover is slidably connected to the outer surface of the casing.

[0010] Furthermore, the inner walls on both sides of the extrusion box are slidably connected to the outer surfaces on both sides of the connecting plate, the outer surface of the water tank is fixedly connected to the inner wall of the surrounding device, and the end of the water pipe away from the roller is fixedly connected to the inner wall of the extrusion box.

[0011] Furthermore, the side of the stop plate proximal to the roller is rotatably connected to the roller's outer surface, the inner wall of the L-shaped plate is fixedly connected to the outer surface of the water pipe, and the shield is positioned between the roller and the welding gun. During extension, the telescopic rod surrounding the bottom of the device causes the connecting plate, the extrusion box, the welding gun, the water pipe, and the roller to move toward the surface of the special-shaped pipe until the roller is in contact with the surface of the special-shaped pipe.

[0012] Furthermore, the pressing component includes a supporting plate, the inner wall of which is slidably connected to an extrusion block, the outer surface of which is fixedly connected to a limit tube, the side of the extrusion block close to the limit tube being fixedly connected to a telescopic spring, and the end of the telescopic spring away from the extrusion block being fixedly connected to a clamping block. The upper surfaces of the clamping block and the extrusion block are both convex arc-shaped, while the middle portion is a concave arc-shaped surface.

[0013] Furthermore, the bottom of the carrier plate is fixedly connected to the upper surface of the housing, the outer surface of the limiting tube is slidably connected to the inner wall of the pressing block, the end of the telescopic spring away from the extrusion block is fixedly connected to the inner wall of the pressing block, and the bottom of the pressing block is slidably connected to the inner wall of the carrier plate. During the downward pressing process, the special-shaped tube first contacts the raised curved surface and presses against the extrusion blocks and the pressing blocks on both sides, forcing the extrusion blocks and the pressing blocks to slide along the inner surface of the carrier plate toward the side away from the special-shaped tube. During the sliding process, the limiting tube slides outward on the inner wall of the pressing block, and the telescopic spring on the inner wall of the pressing block is stretched.

[0014] Furthermore, the protective component includes a servo motor, the bottom of the servo motor is fixedly connected to a support seat, the output shaft of the servo motor is fixedly connected to an arc plate, and the end of the arc plate away from the servo motor is fixedly connected to the protective plate.

[0015] Furthermore, the bottom of the support base is fixedly connected to the upper surface of the connecting plate, and the curved plates are symmetrically arranged on both sides of the welding gun. A servo motor drives the curved plates and the protective plates to rotate toward one side of the welding gun until the left and right protective plates are attached to the outer surface of the welding gun.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The surrounding device can also make the roller roll along the outer surface of the special-shaped tube while driving the roller to rotate in a circular motion. Therefore, the extrusion force of the special-shaped tube on the roller will change with the change of the contact position between the roller and the surface of the special-shaped tube. The roller after being squeezed will drive the moving box and the welding gun to move. Therefore, the device can make the welding gun automatically adjust its position according to the position of the special-shaped tube to be welded, so that the center of the rotary welding and the center of the special-shaped tube connection always coincide with each other, ensuring that the weld seam at the connection always remains complete and continuous during the rotary welding of special-shaped tubes of different diameters, thereby solving the problem of poor welding quality of special-shaped tubes for electric vehicles.

[0018] (2) When the roller rotates to the upper surface of the special-shaped tube, the water inside the water tank can flow into the roller. At the same time, the small filter holes on the roller surface can make the water inside the roller flow to the surface of the special-shaped tube, washing away the debris attached to the surface of the special-shaped tube, and preventing the debris from adhering to the surface of the roller. As a result, the debris will hinder the roller from rotating in the process of fitting the special-shaped tube surface and cause bumps, further affecting the welding accuracy of the welding gun on the special-shaped tube connection. At the same time, the shield can block most of the debris splashed during the welding process during the roller rotation, reducing the amount of debris splashing onto the outer surface of the roller near the welding gun, preventing the roller from being attached to the hot debris, and reducing the cost of cleaning the debris on the roller surface.

[0019] (3) During the welding process of the special-shaped tube, the arc plate and the protective plate wrap the outer surface of the welding gun. When the roller rotates to the surface of the convex side of the special-shaped tube, the roller is squeezed by the convex side of the special-shaped tube, which can drive the welding gun to slide toward the arc plate and the protective plate, thereby scraping off the debris attached to the surface of the welding gun. Because the convex parts on both sides of the special-shaped tube are in a horizontal position, the scraped debris will fall directly into the inside of the casing, and will not fall on the connection of the special-shaped tube surface, preventing the welding gun from welding the gap and debris at the connection together, thereby improving the welding quality of the weld. The device uses the shape of the special-shaped tube to effectively scrape off the debris on the surface of the welding gun, thereby preventing the hot debris from adhering to the outer surface of the welding gun and causing damage to the welding gun.

[0020] (4) The extrusion block and the pressing block can clamp the special-shaped tubes of different widths under the elasticity of the telescopic spring, avoiding the problem of only being able to fix the special-shaped tubes of a single width. At the same time, the clamping effect of the equipment on the special-shaped tubes can enable the roller to effectively clamp the special-shaped tubes when rolling on the surfaces of different special-shaped tubes, avoiding the problem of shaking of the special-shaped tubes during the welding process.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] For the first embodiment, please refer to Figure 1-Figure 7 The present invention is a special-shaped pipe processing and welding device for electric vehicles, comprising a housing 1, an inner wall of the housing 1 being rotatably connected to a rotating shaft 2, an outer surface of the rotating shaft 2 being fixedly connected to a protective cover 3, and an upper surface of the housing 1 being fixedly connected to a pressing component 4;

[0032] The processing and welding equipment also has:

[0033] The surrounding mechanism 5 includes a fixed plate 51, a ring rail 52 fixedly connected to the side of the fixed plate 51 away from the casing 1, a surrounding device 53 rotatably connected to the outer surface of the ring rail 52, a telescopic rod 54 fixedly connected to the bottom of the surrounding device 53, a connecting plate 55 fixedly connected to the end of the telescopic rod 54 away from the surrounding device 53, an extrusion spring 56 fixedly connected to the side of the connecting plate 55 away from the telescopic rod 54, and protective components 7 hinged at both ends of the connecting plate 55; the surrounding device 53 rotates along the surface of the ring rail 52, and the ring rail 52 is arranged in the middle of the casing 1, wherein the surrounding device 53 rotates around the outer surface of the ring rail 52 and drives the rotation of the telescopic rod 54 and the connecting plate 55.

[0034] The rolling component 6 includes an extrusion box 61. A welding gun 62 is fixedly connected to the side of the extrusion box 61 away from the connecting plate 55. A hose 63 is fixedly connected to both sides of the extrusion box 61. The end of the hose 63 away from the extrusion box 61 is fixedly connected to a water tank 64. A water pipe 65 is provided below the hose 63. The outer surface of the water pipe 65 has a water flow hole 66. The end of the water pipe 65 away from the extrusion box 61 is rotatably connected to a roller 67. The water pipe 65 is made of a hard material.

[0035] The outer surface of the roller 67 is provided with filter holes 601. The outer surface of the water pipe 65 is fixedly connected to a limit plate 602. An L-shaped plate 603 is fixedly connected to the side of the limit plate 602 away from the roller 67. A shielding plate 604 is fixedly connected to the side of the L-shaped plate 603 away from the limit plate 602. There are a large number of filter holes 601.

[0036] The bottom end of the fixing plate 51 is fixedly connected to the upper surface of the casing 1 , the end of the extrusion spring 56 away from the connecting plate 55 is fixedly connected to the outer surface of the extrusion box 61 , and the inner wall of the protective cover 3 is slidably connected to the outer surface of the casing 1 .

[0037] The inner walls on both sides of the extrusion box 61 are slidably connected to the outer surfaces on both sides of the connecting plate 55, the outer surface of the water tank 64 is fixedly connected to the inner wall of the surrounding device 53, and the end of the water pipe 65 away from the roller 67 is fixedly connected to the inner wall of the extrusion box 61.

[0038] The side of the limiting plate 602 close to the roller 67 is rotatably connected to the outer surface of the roller 67 , the inner wall of the L-shaped plate 603 is fixedly connected to the outer surface of the water pipe 65 , and the shielding plate 604 is arranged between the roller 67 and the welding gun 62 .

[0039] The pressing component 4 includes a supporting plate 41, the inner wall of which is slidably connected to an extrusion block 42. The outer surface of the extrusion block 42 is fixedly connected to a limit tube 43. A telescopic spring 44 is fixedly connected to the side of the extrusion block 42 close to the limit tube 43. A pressing block 45 is fixedly connected to the end of the telescopic spring 44 away from the extrusion block 42. The upper surfaces of the pressing block 45 and the extrusion block 42 are both convex arc-shaped, while the middle part is a concave arc-shaped surface.

[0040] The bottom of the supporting plate 41 is fixedly connected to the upper surface of the casing 1, the outer surface of the limiting tube 43 is slidingly connected to the inner wall of the clamping block 45, the end of the telescopic spring 44 away from the extrusion block 42 is fixedly connected to the inner wall of the clamping block 45, and the bottom of the clamping block 45 is slidingly connected to the inner wall of the supporting plate 41.

[0041] During use, first, when there is no need to weld the special-shaped tube, the protective cover 3 is snapped onto the outer surface of the casing 1 to prevent external dust from entering the interior of the protective cover 3. When the special-shaped tube needs to be welded, the staff rotates the protective cover 3 outward around the rotating shaft 2 to open the internal space surrounded by the protective cover 3 and the casing 1.

[0042] When fixing the special-shaped tube, the staff places the special-shaped tube above the extrusion block 42 and the pressing block 45, and then presses the special-shaped tube downward toward the middle position of the limiting tube 43. The uppermost surfaces of the extrusion block 42 and the pressing block 45 are set to a convex arc, and the lower surface is set to a concave arc. Therefore, the special-shaped tube first contacts the convex arc surface during the downward pressing process, and is squeezed toward the extrusion blocks 42 and the pressing blocks 45 on both sides, forcing the extrusion blocks 42 and the pressing blocks 45 to slide along the inner surface of the supporting plate 41 toward the side away from the special-shaped tube. During the sliding process, the limiting tube 43 slides outward on the inner wall of the pressing block 45, and the telescopic spring 44 on the inner wall of the pressing block 45 is stretched. When the special-shaped tube is pressed down continuously until it fits into the concave arc surface, the staff no longer presses the special-shaped tube. Under the tension of the telescopic spring 44, the special-shaped tube is fit by the extrusion blocks 42 and the pressing blocks 45 on both sides, thereby achieving an automatic fixing effect on the special-shaped tube.

[0043] Before welding the special-shaped tube, the special-shaped tube port in the present invention is elliptical in shape. The telescopic rod 54 located at the bottom of the surrounding device 53 can move the connecting plate 55 and the extrusion box 61, the welding gun 62, the water pipe 65 and the roller 67 toward the surface close to the special-shaped tube during the extension process until the roller 67 is in contact with the surface of the special-shaped tube. The telescopic rod 54 stops extending. At this time, the welding port of the welding gun 62 is also close to the connection between the two special-shaped tubes. The welding gun 62 is started to weld the connection between the two special-shaped tubes.

[0044] When welding the special-shaped tube, the bottom end of the fixed plate 51 is fixedly connected to the upper surface of the casing 1, so the ring rail 52 is fixed by the fixed plate 51, and the surrounding device 53 can rotate in a circle along the outer surface of the ring rail 52 during operation. The surrounding device 53 can drive the rotation of the telescopic rod 54 and the connecting plate 55 during the rotation, and the connecting plate 55 can also drive the extrusion box 61, the welding gun 62 at the bottom of the extrusion box 61, the water pipe 65, and the roller 67 to rotate around the surface of the special-shaped tube during the rotation. Therefore, the welding gun 62 can perform circumferential welding on the gap at the connection of the two special-shaped tubes during the rotation. During the welding process, the surrounding device 53 rotates at a relatively slow speed, so the roller 67 can rotate slowly in contact with the surface of the shaped tube. When the roller 67 rotates in contact with the outer surface of the elliptical shaped tube, the roller 67 rotates from the smooth side of the shaped tube to the outer surface of the convex side of the shaped tube. The convex side of the shaped tube exerts a squeezing force on the roller 67, causing the two rollers 67 to drive the water pipe 65 and the squeeze box 61 to move toward the side close to the connecting plate 55. During the movement of the squeeze box 61, the inner surface of the squeeze box 61 slides against the outer surface of the connecting plate 55, and the squeeze box 61 also squeezes the squeezing spring 56. The squeezing of the shaped tube on the roller 67 drives the moving box and the welding gun 62 at the bottom of the moving box to move, so that the welding gun 62 can automatically adjust its position according to the position of the shaped tube to be welded, avoiding the problem of the center of the rotation welding not coinciding with the center of the shaped tube joint, resulting in an incomplete weld surface at the connection of the two shaped tubes.

[0045] As the water pipe 65 drives the roller 67 to rotate against the outer surface of the special-shaped tube, the roller 67 rotates around the outer surface of the water pipe 65, and the water pipe 65 can also drive the rotation of the L-shaped plate 603 and the shield 604. When the roller 67 is located on the upper surface of the special-shaped tube, the water inside the water tank 64 can enter the interior of the squeeze box 61 through the hose 63. The interior of the squeeze box 61 is hollow, so the water inside the squeeze box 61 can enter the interior of the water pipe 65, and then enter the interior of the roller 67 through the water flow hole 66 on the surface of the water pipe 65. Finally, it flows through the filter hole 601 on the surface of the roller 67 to the outer surface of the special-shaped tube. The material of the water pipe 65 is hard, not soft. The moisture inside roller 67 effectively cools roller 67. Simultaneously, the moisture flows to the surface of the shaped tube, rapidly cooling the area near the weld joint and washing away debris adhering to the surface of the shaped tube, preventing it from adhering to the surface of roller 67 and causing positional deviation of roller 67 during rotation relative to the shaped tube. The limiting tube 43 limits the position of roller 67 during its rotation, while the shield 604 blocks most of the debris splashed by the welding process, preventing it from splashing onto the outer surface of roller 67 and causing damage to it.

[0046] When the water tank 64, the squeeze box 61, and the roller 67 rotate to the bottom surface of the special-shaped tube, the water tank 64 is located below the squeeze box 61 and the roller 67. Therefore, the water inside the water tank 64 cannot enter the squeeze box 61 through the hose 63, and the water also cannot enter the roller 67, thus avoiding the problem of water waste. Only when the roller 67 rotates to the top of the special-shaped tube will water enter the roller 67, cooling the roller 67 and achieving other effects.

[0047] For the second embodiment, please refer to Figures 1-8 The present invention is a special-shaped pipe processing and welding device for electric vehicles. The protective component 7 includes a servo motor 71. The bottom of the servo motor 71 is fixedly connected to a support seat 72. The output shaft of the servo motor 71 is fixedly connected to an arc plate 73. The end of the arc plate 73 away from the servo motor 71 is fixedly connected to a protective plate 74.

[0048] The bottom of the support base 72 is fixedly connected to the upper surface of the connecting plate 55 , and the arc-shaped plates 73 are symmetrically arranged on both sides of the welding gun 62 .

[0049] During use, when welding is to be performed, the servo motor 71 is activated and drives the arc plate 73 and the protective plate 74 to rotate, causing the arc plate 73 and the protective plate 74 to rotate toward the side of the welding gun 62 until the left and right protective plates 74 are in contact with the outer surface of the welding gun 62, covering the upper surface of the welding gun 62. When the roller 67 rotates from the smooth side of the special-shaped tube to the outer surface of the raised side, the roller 67 drives the water pipe 65, the squeeze box 61, and the welding gun 62 toward the connecting plate 55. As the welding gun 62 moves, it slides along the inner wall of the protective plate 74 toward the side close to the connecting plate 55. Debris attached to the surface of the welding gun 62 can be scraped off by the protective plate 74. Because the raised areas on both sides of the special-shaped tube are horizontal, the protective plates 74 are also horizontal. The scraped off debris will fall directly into the interior of the housing 1 and will not fall on the surface of the special-shaped tube. The shape of the special-shaped tube can effectively scrape off the debris on the surface of the welding gun 62, preventing the hot debris from adhering to the outer surface of the welding gun 62 and causing damage to the welding gun 62.

[0050] If welding gun 62 becomes damaged, servo motor 71 drives curved plate 73 and protective plate 74 to reset, facilitating repair and replacement of welding gun 62. Once welding is complete, the welded shaped tube is removed from the inner walls of extrusion block 42 and compression block 45, and then from the center of ring rail 52. Moisture and most debris released during use will fall into housing 1, facilitating subsequent collection and centralized cleaning.

[0051] The specific workflow is as follows:

[0052] First, when fixing the special-shaped tube, the staff places the special-shaped tube above the extrusion block 42 and the clamping block 45, and then presses the special-shaped tube downward toward the middle position of the limiting tube 43. The uppermost surfaces of the extrusion block 42 and the clamping block 45 are set to a convex arc, and the lower surface is set to a concave arc. The special-shaped tube is clamped by the clamping blocks 45 and the extrusion block 42 on the left and right sides.

[0053] Before welding the special-shaped tube, the telescopic rod 54 can move the connecting plate 55, the extrusion box 61, the welding gun 62, the water pipe 65 and the roller 67 toward the surface close to the special-shaped tube during the extension process until the roller 67 is in contact with the surface of the special-shaped tube. The telescopic rod 54 stops extending, and the welding port of the welding gun 62 is also close to the connection between the two special-shaped tubes. The welding gun 62 is started to weld the connection between the two special-shaped tubes.

[0054] When welding a special-shaped pipe, the surrounding device 53 rotates in a circular motion along the outer surface of the ring rail 52 during operation, driving the telescopic rod 54 and the connecting plate 55 to rotate. During this rotation, the connecting plate 55 also drives the extrusion box 61, the welding gun 62 at the bottom of the extrusion box 61, the water pipe 65, and the roller 67 to rotate around the surface of the special-shaped pipe. Therefore, the welding gun 62 can perform circular welding on the gap at the connection between the two special-shaped pipes during this rotation. When the roller 67 rotates along the outer surface of the oval special-shaped pipe, as the roller 67 rotates from the smooth side of the special-shaped pipe to the outer surface of the raised side of the special-shaped pipe, the raised side of the special-shaped pipe exerts a squeezing force on the roller 67, causing the two rollers 67 to drive the water pipe 65 and the extrusion box 61 to move toward the side closer to the connecting plate 55. During this movement, the inner surface of the extrusion box 61 slides against the outer surface of the connecting plate 55, and the extrusion box 61 also compresses the extrusion spring 56 during this movement. The compression of roller 67 by the special-shaped tube drives the movement of the movable box and the welding gun 62 at its bottom, allowing the welding gun 62 to automatically adjust its position according to the desired welding location on the special-shaped tube. As the water pipe 65 drives roller 67 to rotate against the outer surface of the special-shaped tube, roller 67 rotates around the outer surface of the water pipe 65, driving the L-shaped plate 603 and shield 604 to rotate. When the roller 67 is located on the upper surface of the special-shaped tube, the water inside the water tank 64 can enter the interior of the extrusion box 61 through the hose 63. The interior of the extrusion box 61 is hollow, so the water inside the extrusion box 61 can enter the interior of the water pipe 65, and then enter the interior of the roller 67 through the water flow hole 66 opened on the surface of the water pipe 65, and then flow to the outer surface of the special-shaped tube through the filter hole 601 opened on the surface of the roller 67. At the same time, the water flows to the surface of the special-shaped tube, and can also quickly cool the position near the welding point of the special-shaped tube and wash away the debris attached to the surface of the special-shaped tube. The shield 604 can block most of the debris splashed by the welding when the roller 67 is rotating.

[0055] When protecting the welding gun 62, the servo motor 71 is activated, driving the arc plate 73 and the protective plate 74 to rotate, causing the arc plate 73 and the protective plate 74 to rotate toward the side of the welding gun 62 until the left and right protective plates 74 are attached to the outer surface of the welding gun 62, covering the upper surface of the welding gun 62. When the roller 67 rotates from the smooth side of the special-shaped tube to the outer surface of the raised side, the roller 67 drives the water pipe 65, the squeeze box 61, and the welding gun 62 toward the connecting plate 55. Therefore, during the movement, the welding gun 62 slides along the inner wall of the protective plate 74 toward the side close to the connecting plate 55, and debris attached to the surface of the welding gun 62 can be scraped off by the protective plate 74.

[0056] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
