Description

Technical Field

[0001] The 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-driven vehicles, use batteries as their energy source. They use the vehicle's controller, motor and other components to convert electrical energy into mechanical energy to change speed by controlling the current. Electric vehicles greatly facilitate transportation in daily use and play an indispensable role. Before the production and assembly of electric vehicles, some pipes need to be welded, and some of the pipes have special-shaped pipes. Special-shaped pipes are a general term for seamless steel pipes with other cross-sectional shapes except round pipes.

[0003] In the process of processing and welding special-shaped pipes for electric vehicles, since the pipes are of special shapes, when performing rotation welding on 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 at the joint during the rotation welding process, which further leads to the problem of poor welding quality of special-shaped pipes for electric vehicles. Therefore, the present invention designs a special-shaped pipe processing and welding equipment for electric vehicles for elliptical special-shaped pipes to solve the above problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an electric vehicle special-shaped pipe processing and welding device, comprising a housing, 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; The processing and welding equipment also has: The surrounding mechanism includes a fixed plate, a side of the fixed plate away from the casing is fixedly connected to a ring rail, the outer surface of the ring rail is rotatably connected to a surrounding device, the bottom of the surrounding device is fixedly connected to a telescopic rod, the end of the telescopic rod away from the surrounding device is fixedly connected to a connecting plate, the side of the connecting plate away from the telescopic rod is fixedly connected to an extrusion spring, and the outer surface of the surrounding mechanism is fixedly connected to a protective component; 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 telescopic rod and the connecting plate to rotate.

[0005] The rolling component includes an extrusion box, a welding gun is fixedly connected to the side of the extrusion box away from the connection plate, hoses are fixedly connected to both sides of the extrusion box, one end of the hose away from the extrusion box is fixedly connected to a water tank, a water pipe is arranged below the hose, a water flow hole is opened on the outer surface of the water pipe, and a roller is rotatably connected to the end of the water pipe away from the extrusion box. The material of the water pipe is a hard material.

[0006] Furthermore, the outer surface of the roller is provided with filter holes, the outer surface of the water pipe is fixedly connected with a limit plate, the side of the limit plate away from the roller is fixedly connected with an L-shaped plate, and the side of the L-shaped plate away from the limit plate is fixedly connected with a shielding plate. The number of filter holes is relatively large.

[0007] Furthermore, the bottom end of the fixing 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.

[0008] Furthermore, the inner wall of the extrusion box is slidably connected to the outer surface of the connecting plate, the outer surface of the water box 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.

[0009] Furthermore, the side of the limit plate close to the roller is rotatably connected to the outer surface of the roller, the inner wall of the L-shaped plate is fixedly connected to the outer surface of the water pipe, and the shield is arranged between the roller and the welding gun. The telescopic rod surrounding the bottom of the device can move the connecting plate, the extrusion box, the welding gun, the water pipe and the roller toward the surface close to the special-shaped pipe during the extension process until the roller fits on the surface of the special-shaped pipe.

[0010] Furthermore, the pressing component includes a bearing plate, the inner wall of the bearing plate is slidably connected with an extrusion block, the outer surface of the extrusion block is fixedly connected with a limit tube, the side of the extrusion block close to the limit tube is fixedly connected with a telescopic spring, and the end of the telescopic spring away from the extrusion block is fixedly connected with a clamping block. The upper surfaces of the clamping block and the extrusion block are both convex arc surfaces, and the middle part is a concave arc surface.

[0011] Furthermore, the bottom of the carrier plate is fixedly connected to the upper surface of the housing, the outer surface of the limit 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 arc surface and presses 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 to the side away from the special-shaped tube. During the sliding process, the limit 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.

[0012] Furthermore, the protective component includes a servo motor, a support base is fixedly connected to the bottom of the servo motor, an arc plate is fixedly connected to the output shaft of the servo motor, and a protective plate is fixedly connected to one end of the arc plate away from the servo motor.

[0013] Furthermore, the bottom of the support seat is fixedly connected to the upper surface of the connecting plate, and the arc plates are symmetrically arranged on both sides of the welding gun. The servo motor drives the arc plate and the protective plate to rotate, so that the arc plate and the protective plate rotate toward one side of the welding gun until the protective plates on the left and right sides are attached to the outer surface of the welding gun.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) When the surrounding device drives the roller to rotate in a circular motion, the roller can also roll against the outer surface of the special-shaped tube. 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 where the special-shaped tube needs to be welded, so that the center of the rotary welding and the center of the connection of the special-shaped tube always keep coincidence, ensuring that the device can rotate and weld special-shaped tubes of different diameters, so that the weld at the connection always keeps the characteristics of complete and coherent, thereby solving the problem of poor welding quality of special-shaped tubes of electric vehicles.

[0015] (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 fine 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, which causes the roller to be blocked by debris and bumps during the rotation process of the roller in contact with the surface of the special-shaped tube, further affecting the welding accuracy of the welding gun at the connection of the special-shaped tube. At the same time, the shield can block most of the debris splashed during the welding process during the rotation of the roller, reduce the amount of debris splashed to the outer surface of the roller close to the welding gun, prevent the roller from being attached by hot debris, and reduce the cost of cleaning the debris on the roller surface.

[0016] (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 raised side of the special-shaped tube, the roller is squeezed by the raised 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 raised 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 instead of falling on the connection of the special-shaped tube surface, preventing the welding gun from welding the gap at the connection and the debris 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.

[0017] (4) The extrusion block and the clamping block can clamp the special-shaped tubes of different widths under the elasticity of the telescopic spring, avoiding the problem of only fixing the special-shaped tubes of a single width. At the same time, the clamping effect of the equipment on the special-shaped tube can make the roller effectively clamp the special-shaped tube when rolling on the surface of different special-shaped tubes, avoiding the problem of shaking of the special-shaped tube during the welding process.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.

[0021] For the first embodiment, please refer to Figure 1-Figure 7The present invention is a welding device for processing special-shaped pipes of electric vehicles, comprising a housing 1, a rotating shaft 2 is rotatably connected to the inner wall of the housing 1, a protective cover 3 is fixedly connected to the outer surface of the rotating shaft 2, and a pressing component 4 is fixedly connected to the upper surface of the housing 1; The processing and welding equipment also has: The surrounding mechanism 5 includes a fixed plate 51, a side of the fixed plate 51 away from the housing 1 is fixedly connected to a ring rail 52, the outer surface of the ring rail 52 is rotatably connected to a surrounding device 53, the bottom of the surrounding device 53 is fixedly connected to a telescopic rod 54, the end of the telescopic rod 54 away from the surrounding device 53 is fixedly connected to a connecting plate 55, the side of the connecting plate 55 away from the telescopic rod 54 is fixedly connected to an extrusion spring 56, and the outer surface of the surrounding mechanism 5 is fixedly connected to a protective component 7; 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 housing 1, wherein the surrounding device 53 rotates around the outer surface of the ring rail 52 and drives the telescopic rod 54 and the connecting plate 55 to rotate.

[0022] 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, an end of the hose 63 away from the extrusion box 61 is fixedly connected to a water tank 64, a water pipe 65 is arranged below the hose 63, a water flow hole 66 is opened on the outer surface of the water pipe 65, and a roller 67 is rotatably connected to the end of the water pipe 65 away from the extrusion box 61. The material of the water pipe 65 is a hard material.

[0023] 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, the side of the limit plate 602 away from the roller 67 is fixedly connected to an L-shaped plate 603, and the side of the L-shaped plate 603 away from the limit plate 602 is fixedly connected to a shielding plate 604. The number of filter holes 601 is relatively large.

[0024] 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 .

[0025] The inner wall of the extrusion box 61 is slidably connected to the outer surface of the connecting plate 55 , the outer surface of the water box 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 .

[0026] 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 .

[0027] The pressing component 4 includes a bearing plate 41, the inner wall of which is slidably connected to a squeezing block 42, the outer surface of which is fixedly connected to a limiting tube 43, a telescopic spring 44 is fixedly connected to the side of the squeezing block 42 close to the limiting tube 43, and a clamping block 45 is fixedly connected to the end of the telescopic spring 44 away from the squeezing block 42. The upper surfaces of the clamping block 45 and the squeezing block 42 are both convex arc surfaces, and the middle part is a concave arc surface.

[0028] 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 slidably 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 slidably connected to the inner wall of the supporting plate 41.

[0029] When in use, first, when there is no need to weld the special-shaped tube, the protective cover 3 is snapped on the outer surface of the casing 1 to prevent external dust from entering the interior of the protective cover 3. When it is necessary to weld the special-shaped tube, the staff rotates the protective cover 3 outward around the rotating shaft 2 to open the internal space enclosed by the protective cover 3 and the casing 1.

[0030] 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 surfaces are 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 clamping blocks 45 on both sides, forcing the extrusion blocks 42 and the clamping 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 clamping block 45, and the telescopic spring 44 on the inner wall of the clamping 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.

[0031] Before welding the special-shaped tube, the port of the special-shaped tube 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 fits the surface of the special-shaped tube, and 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.

[0032] 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, so the welding gun 62 can perform circular welding on the gap at the connection of the two special-shaped tubes during the rotation. During the welding process, the speed of the surrounding device 53 is relatively slow, so the roller 67 can rotate slowly in contact with the surface of the special-shaped tube. When the roller 67 rotates from the smooth side of the special-shaped tube to the outer surface of the convex side while in contact with the outer surface of the elliptical special-shaped tube, the convex side of the special-shaped tube will exert an extrusion force on the roller 67, so that the two rollers 67 drive the water pipe 65 and the extrusion box 61 to move toward the side close to the connecting plate 55. During the movement of the extrusion box 61, the inner surface of the extrusion box 61 slides with the outer surface of the connecting plate 55, and the extrusion box 61 also squeezes the extrusion spring 56 during the movement. The extrusion of the roller 67 by the special-shaped tube can drive the movement of the moving box and the welding gun 62 at the bottom of the moving box, so that the welding gun 62 can automatically adjust its position according to the position of the special-shaped tube to be welded, so as to avoid the center of the rotation welding not coinciding with the center of the joint of the special-shaped tube, resulting in the problem of incomplete welding surface at the connection of the two special-shaped tubes.

[0033] When the water pipe 65 drives the roller 67 to rotate in contact with the outer surface of the special-shaped tube, the roller 67 will rotate 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 shielding plate 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 inside of the squeeze box 61 through the hose 63. The inside of the squeeze box 61 is hollow, so the water inside the squeeze box 61 can enter the inside of the water pipe 65, and then enter the inside 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. The material of the water pipe 65 is hard water pipe 65, not soft. The moisture inside the roller 67 can have a good cooling effect on the roller 67. At the same time, the moisture flows to the surface of the special-shaped tube, and can also quickly cool down the position near the welding point of the special-shaped tube, and can also wash away the debris attached to the surface of the special-shaped tube, so as to prevent the debris from adhering to the surface of the roller 67, causing the roller 67 to be offset when it rotates in contact with the surface of the special-shaped tube. The limiting tube 43 limits the roller 67 during the rotation of the roller 67, and the shielding plate 604 can block most of the debris splashed by the welding when the roller 67 is rotating, so as to prevent the debris from splashing to the outer surface of the roller 67, causing damage to the roller 67.

[0034] When the water tank 64, the squeeze box 61 and the roller 67 rotate to the lower surface of the special-shaped tube, the water tank 64 is located below the squeeze box 61 and the roller 67, so the water inside the water tank 64 cannot enter the squeeze box 61 through the hose 63, and the water will not enter the roller 67, thereby avoiding the problem of water waste. Only when the roller 67 rotates to the top of the special-shaped tube, water will enter the roller 67 to cool the roller 67 and produce other effects.

[0035] For the second embodiment, please refer to Figure 1-Figure 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.

[0036] The bottom of the support seat 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 .

[0037] When in use, when welding is to be performed, the servo motor 71 is started and drives the arc plate 73 and the protective plate 74 to rotate, so that the arc plate 73 and the protective plate 74 rotate toward the side of the welding gun 62, until the protective plates 74 on the left and right sides are attached to the outer surface of the welding gun 62, and the upper surface of the welding gun 62 is wrapped. When the roller 67 rotates from the smooth side of the special-shaped tube to the outer surface of the protruding side, the roller 67 drives the water pipe 65, the extrusion box 61 and the welding gun 62 to move toward the connecting plate 55, so that the welding gun 62 will slide along the inner wall of the protective plate 74 toward the side close to the connecting plate 55 during the movement, and the debris attached to the surface of the welding gun 62 can be scraped off by the protective plate 74, because the protruding parts on both sides of the special-shaped tube are in a horizontal position, so the protective plate 74 is also in a horizontal position, and the scraped debris will directly fall 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 be used to effectively scrape off the debris on the surface of the welding gun 62, thereby preventing the hot debris from adhering to the outer surface of the welding gun 62 and causing damage to the welding gun 62.

[0038] When the welding gun 62 is damaged, the servo motor 71 drives the arc plate 73 and the protective plate 74 to reset, which is also convenient for the maintenance and replacement of the welding gun 62. When the welding is completed, the staff will take out the welded special-shaped tube from the inner wall of the extrusion block 42 and the pressing block 45, and then take it out from the center of the ring track 52. The moisture and most of the debris in the use process will fall into the inside of the housing 1, which is convenient for subsequent collection and centralized cleaning.

[0039] The specific workflow is as follows: 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 clamping of the special-shaped tube is achieved by the clamping blocks 45 and the extrusion blocks 42 on the left and right sides.

[0040] 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 fits 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.

[0041] When welding the special-shaped pipe, the surrounding device 53 rotates in a circle along the outer surface of the ring rail 52 during operation, and can drive the telescopic rod 54 and the connecting plate 55 to rotate. 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 pipe during the rotation process, so the welding gun 62 can perform circular welding on the gap at the connection of the two special-shaped pipes during the rotation process. When the roller 67 rotates in the process of fitting the outer surface of the elliptical special-shaped pipe, the roller 67 rotates from the smooth side of the special-shaped pipe to the outer surface of the convex side, the convex side of the special-shaped pipe will have an extrusion force on the roller 67, so that the two rollers 67 drive the water pipe 65 and the extrusion box 61 to move to the side close to the connecting plate 55, and the inner surface of the extrusion box 61 slides with the outer surface of the connecting plate 55 during the movement of the extrusion box 61, and the extrusion box 61 will also squeeze the extrusion spring 56 during the movement. The special-shaped tube squeezes the roller 67, which can drive 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 special-shaped tube to be welded. When the water pipe 65 drives the roller 67 to rotate in contact with the outer surface of the special-shaped tube, the roller 67 will rotate around the outer surface of the water pipe 65, and the water pipe 65 can also drive the L-shaped plate 603 and the shielding plate 604 to rotate. When the roller 67 is located on the upper surface of the special-shaped tube, the water in the water tank 64 can enter the extrusion box 61 through the hose 63. The interior of the extrusion box 61 is hollow, so the water in the extrusion box 61 can enter the water pipe 65, and then enter 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 the vicinity of the welding point of the special-shaped tube can be quickly cooled down, and the debris attached to the surface of the special-shaped tube can be washed away. The shield 604 can block most of the debris splashed by welding when the roller 67 is rotating.

[0042] When protecting the welding gun 62, the servo motor 71 starts and drives the arc plate 73 and the protective plate 74 to rotate, so that the arc plate 73 and the protective plate 74 rotate on the side facing the welding gun 62 until the protective plates 74 on the left and right sides are attached to the outer surface of the welding gun 62 and wrap 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 convex side, the roller 67 drives the water pipe 65, the extrusion box 61 and the welding gun 62 to move toward the connecting plate 55, so that the welding gun 62 slides along the inner wall of the protective plate 74 to the side close to the connecting plate 55 during the movement, and the debris attached to the surface of the welding gun 62 can be scraped off by the protective plate 74.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
