Description

Technical Field

[0001] The invention belongs to the technical field of automobile processing, in particular to an automobile pipe welding device. Background Art

[0002] Some pipes inside the car are not round pipes. For example, the exhaust pipe and other structures are special-shaped pipes. The processing technology of assembling special-shaped pipes by welding can produce parts with complex shapes and positions to meet the needs of automobile processing. For small-sized special-shaped pipe welding assemblies with high sealing requirements but low load-bearing requirements, they are generally processed by soft solder brazing on special welding equipment.

[0003] When welding special-shaped pipes, a large amount of welding slag will be generated at the connection parts of the pipes to ensure the tightness of the connection structure between the pipes. Therefore, the welding slag needs to be ground after welding to reduce the weight, aesthetics and practicality of the pipes and prevent slag from falling off when the pipes are used. However, during the grinding work, since the pipes are not uniform arc structures, the grinding force on the pipes will be different, which will lead to a worse slag removal effect of the pipes, so the welding equipment needs to be improved.

[0006] Furthermore, an arc-shaped groove is provided at the top of the inner cavity of the counterweight plate, and a side push rod is symmetrically provided on the inner wall of the arc-shaped groove. The top of the side push rod is arc-shaped and can be pushed upward by itself. The top of the side push rod is rotatably connected with a docking sleeve, and the docking sleeve is connected to the arc surface of the top of the side push rod through the groove of the inner wall. The docking sleeve is always adsorbed on the metal plane at the top of the inner wall of the adjustment base, and can also slide along the top of the inner wall of the adjustment base, but will not detach from the top of the inner wall of the adjustment base. The axis of the upper surface of the counterweight plate is rotatably connected to the axis of the top of the inner wall of the adjustment base through a connecting shaft. The upper surface of the docking sleeve is slidably connected to the top of the inner wall of the adjustment base, and the bottom end of the side push rod is slidably connected to the inner cavity of the counterweight plate through a connecting rod.

[0007] Further, the clamping device includes a horizontal support plate, the inner cavity of the horizontal support plate is evenly provided with flat rollers, the outer surface of the horizontal support plate is symmetrically provided with guide side plates on both sides, the upper surface of the guide side plate is slidably connected with a vertical baffle through a guide groove, the inner cavity of the vertical baffle is evenly provided with vertical rollers, and the bottom of the inner cavity of the horizontal support plate is provided with an absorption device, and when clamping a square tube, the flat rollers and the vertical rollers are both in contact with the outer surface of the square tube.

[0009] The beneficial effects of the present invention are as follows: 1. The device can weld the butt joints of special-shaped pipes. When welding is performed by the top welding equipment above, the weld below the special-shaped pipe can be ground by the grinding equipment below, so as to clean up the welding slag at the weld of the pipe fittings. The adjustment base can be deflected to a certain extent under the control and pushing action of the internal side push rod, so that the grinding roller can grind the weld of the pipe body in a changeable direction, and then the grinding force of the pipe fittings can be changed by pushing the grinding roller, and then the different parts of the square pipe can be fine-tuned to achieve a more uniform grinding effect, avoiding the problem of improper grinding force of the square pipe.

[0010] 2. When the square tube of the device is processed, the welding work and the slag treatment work are carried out simultaneously, thereby saving the time consumed by performing a single work, and the processing work of the two can be complementary, that is, the grinding equipment can process the position where the square tube solder is thicker, and the top welding equipment can perform repair welding on the gap after the square tube is ground, thereby compensating for the position where the square tube is over-ground and ensuring the firmness of the square tube welding point position. Through the above-mentioned cyclic processing, the weld of the tube body is guaranteed to be firm, and the retained solder will not be thicker, making the tube body more beautiful.

[0011] 3. The clamping device can fix the placed special-shaped tubes. When the square tube needs to be turned over, the outer surface of the special-shaped tube can be rolled and rubbed by the internal roller to achieve the effect of twisting the special-shaped tube. When the special-shaped tube is not twisted, the static friction of the stationary roller on the outer surface of the special-shaped tube can fix the tube body. The clamping device can fix and automatically turn over special-shaped tubes of different shapes. The vertical baffle can also slide and adjust with the turning action of the special-shaped tube to ensure that the extrusion force is applied to the special-shaped tube for fixing, and can also avoid the problem of extrusion deformation caused by excessive clamping force after the tube body is turned over.

[0012] 4. When the grinding roller below is grinding, the bent hollow plate will slide to a position close to the weld of the square tube through the sliding shaft on the side, thereby lengthening the folding connecting rod so that the position of its air intake groove is close to the weld position below the square tube. Then the side push box starts to suck air, and absorbs the welding slag generated by grinding into the inside of the bent hollow plate. Due to the blocking and filtering work of the filter plate core, the welding slag will not enter the inside of the side push box, ensuring the adsorption force of the side push box, thereby preventing the ground welding slag from falling into the bottom arc shell and affecting the overall deflection work of the grinding equipment.

DETAILED DESCRIPTION

[0015] 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.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0016] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: an automobile pipe welding device, comprising a square tube 1, a clamping device 2 is symmetrically arranged on both sides of the outer surface of the square tube 1, a processing device 4 is arranged at the bottom of the clamping device 2, and a top welding device 3 is arranged on the top of the square tube 1; The top welding device 3 includes a fixed top plate 31, a push slide 32 is evenly arranged at the bottom of the fixed top plate 31, a docking arc shell 33 is fixedly connected to the bottom end of the push slide 32, and a central arc rod 36 is symmetrically arranged on both sides of the lower surface of the docking arc shell 33, and a monitoring lens 37 is evenly arranged in the inner cavity of the central arc rod 36. The central arc rod 36 can monitor the direction of the welding point of the square tube 1 through the monitoring lens 37, and a control slide 34 is slidably connected to the axis of the inner cavity of the docking arc shell 33, and the bottom end of the control slide 34 is fixedly connected to the welding end 35 through the push rod; The processing equipment 4 includes a fixed base 41, and height-adjusting bottom columns 42 are symmetrically arranged on the left and right sides of the upper surface of the fixed base 41. A bottom arc shell 43 is fixedly connected to the axis of the upper surface of the fixed base 41 through a push rod. The bottom arc shell 43 has the same structure as the docking arc shell 33. After the two are docked with each other, a relatively round shell can be formed, and then the square tube 1 can be wrapped inside. Compensation detectors 44 are symmetrically arranged on both sides of the inner wall of the bottom arc shell 43, and a grinding device 6 is arranged in the inner cavity of the bottom arc shell 43.

[0017] The grinding device 6 includes an active slide 61, the top of the active slide 61 is fixedly connected with a connecting push rod 62, the top of the connecting push rod 62 is fixedly connected with a counterweight plate 63, the top of the counterweight plate 63 is fixedly connected with an adjustment base 66, the cylinder part of the adjustment base 66 can be folded and deformed, and the top is a metal round plate, where no deformation will occur, the two sides of the upper surface of the adjustment base 66 are fixedly connected with a torque motor 67 through a vertical frame plate, and the outer surface of the output shaft of the torque motor 67 is fixedly connected with a grinding roller 68, and the control slide 34 has the same structure as the active slide 61, both of which have a connecting push rod 62 that penetrates the corresponding arc shell, and can also perform active sliding motion along the inner wall of its arc shell through the roller on the side. The outer surface of the active slide 61 is slidably connected to the inner cavity of the bottom arc shell 43 through an arc groove, the outer surface of the connecting push rod 62 extends to the outside of the bottom arc shell 43 through the arc groove, and the outer surface of the grinding roller 68 is squeezed against the weld on the outer surface of the square tube 1.

[0018] The top of the inner cavity of the counterweight plate 63 is provided with an arc-shaped groove, and the inner wall of the arc-shaped groove is symmetrically provided with a side push rod 64. The top of the side push rod 64 is arc-shaped, and it can actively push the rod body upward. The top of the side push rod 64 is rotatably connected with a docking sleeve 65, and the docking sleeve 65 is connected with the arc surface of the top of the side push rod 64 through the groove of the inner wall. The docking sleeve 65 is always adsorbed on the metal plane at the top of the inner wall of the adjustment base 66, and can also slide along the top of the inner wall of the adjustment base 66, but will not be separated from the top of the inner wall of the adjustment base 66. The axis of the upper surface of the counterweight plate 63 is rotatably connected with the axis of the top of the inner wall of the adjustment base 66 through the connecting shaft. The upper surface of the docking sleeve 65 is slidably connected with the top of the inner wall of the adjustment base 66, and the bottom end of the side push rod 64 is slidably connected with the inner cavity of the counterweight plate 63 through a connecting rod. Both sides of the outer surface of the active slide plate 61 are slidably connected with the inner cavity of the bottom arc shell 43 through rollers.

[0019] When the device is used to weld square tubes 1, the two square tubes 1 to be welded are placed on the clamping devices 2 on both sides respectively, and then the top heights of the bottom columns 42 on both sides are adjusted to align the square tubes 1 on both sides and butt them together to prepare for welding.

[0020] The push slide bars 32 on the upper and lower sides push the docking arc shell 33 and the bottom arc shell 43 respectively, so that the docking arc shell 33 and the bottom arc shell 43 are engaged and docked together, and the square tube 1 is surrounded inside. Figure 1As shown, the upper welding end 35 then automatically welds the weld position between the square tubes 1 on both sides. During the welding process, the control slide 34 will slide along the inner cavity of the docking arc shell 33, thereby driving the bottom welding end 35 to synchronously deflect along the inner wall of the docking arc shell 33. However, since the docking arc shell 33 is only a half-sectioned arc shell, the actual deflection range of the welding end 35 is limited, and welding work cannot be performed on the other side of the square tube 1. At this time, the clamping devices 2 on both sides are required to assist in cooperating, so as to turn the square tube 1 over, and then achieve comprehensive welding work on the joint of the square tube 1.

[0021] During welding, due to the particularity of the shape of the special-shaped tube, in order to ensure the firmness of the welding at the joint of the tube body, it is necessary to concentrate the monitoring lens 37 of the arc rod 36 to monitor the range of the weld position, and to check for leaks and perform appropriate repair welding. After the joint of the square tube 1 is welded, the welding slag coverage area at the weld will definitely be larger than the actual weld area, so these slags need to be processed. The weld part after flipping will be located at the bottom. At this time, the slag near the weld position can be ground by the grinding equipment 6 at the bottom to remove the excess welding slag.

[0022] After the active slide plate 61 pushes the counterweight plate 63 close to the square tube 1 by connecting the push rod 62, the square tube 1 is polished by the grinding roller 68 rotating at the top height, and the side pushing rods 64 located on both sides of the inner wall of the adjustment base 66 will push the top part of the adjustment base 66 to tilt by raising one side and shortening the other side, thereby changing the grinding focus range of the grinding roller 68, and then applying different extrusion forces and different grinding angles to the outer surface of the square tube 1, thereby completing the grinding of the thicker welding slag.

[0023] Since the top welding equipment 3 will monitor and repair the weld position of the square tube 1 multiple times, the polished weld will be scanned again by the monitoring lens 37 directly above after being flipped. When it is detected that the weld is excessively polished and causes a thinner portion at the weld interface, the top welding equipment 3 will repair and reinforce this more fragile portion. At the same time, the lower grinding equipment 6 is still performing grinding work, and the excess welding slag generated by the welding of the upper top welding equipment 3 is also processed multiple times. After repeating the above work for a period of time, the weld position of the square tube 1 is relatively perfect. At this time, the top welding equipment 3 and the processing equipment 4 can be separated, and the welded rectangular tube 1 can be taken out from the inside of the clamping device 2.

[0024] Example 2, please refer to Figure 1-Figure 7The present invention provides a technical solution: on the basis of embodiment 1, the clamping device 2 comprises a horizontal support plate 21, the inner cavity of the horizontal support plate 21 is evenly provided with flat rollers 22, the outer surface of the horizontal support plate 21 is symmetrically provided with guide side plates 23 on both sides, the upper surface of the guide side plates 23 is slidably connected with a vertical baffle 24 through a guide chute, the inner cavity of the vertical baffle 24 is evenly provided with vertical rollers 25, and the bottom of the inner cavity of the horizontal support plate 21 is provided with an absorption device 5, when clamping the square tube 1, the flat rollers 22 and the vertical rollers 25 are both in contact with the outer surface of the square tube 1. The outer surface of the guide side plate 23 is fixedly connected to the side of the horizontal support plate 21, the outer surface of the flat roller 22 is rotatably connected to the inner cavity of the horizontal support plate 21 through a rotating groove, the bottom end of the vertical baffle 24 is slidably connected to the inner cavity of the guide side plate 23 through a guide chute, and the outer surface of the vertical roller 25 is rotatably connected to the inner cavity of the vertical baffle 24 through a rotating groove.

[0025] The absorption device 5 includes a side push box 51, the inner cavity of the side push box 51 is evenly provided with folding connecting rods 52, the end of the folding connecting rod 52 away from the side push box 51 is fixedly connected with a bent hollow plate 53, the inner cavity of the bent hollow plate 53 is filled with a filter plate core 54 on the side close to the folding connecting rod 52, and sliding shafts 56 are symmetrically provided on the front and rear sides of the outer surface of the bent hollow plate 53, and the end of the inner cavity of the bent hollow plate 53 away from the filter plate core 54 is evenly provided with air intake grooves 55. The end of the sliding shaft 56 away from the bent hollow plate 53 is slidably connected to the bottom of the inner cavity of the horizontal support plate 21 through a guide rail, the axis of the bottom of the inner cavity of the horizontal support plate 21 is fixedly connected to the top of the height adjustment bottom column 42, and the outer surface of the side push box 51 is fixedly connected to the inner cavity of the horizontal support plate 21.

[0026] When the square tube 1 is placed on the clamping device 2, its lower surface will contact the outer surface of the flat roller 22, and the vertical baffles 24 on both sides will be squeezed along the slide groove of the guide side plate 23 to the position close to the side of the square tube 1, so that the side position of the square tube 1 is clamped by the vertical roller 25. When the square tube 1 is flipped, the flat roller 22 and the vertical roller 25 will drive the internally clamped square tube 1 to rotate by active rotation. At the same time, the vertical baffles 24 on both sides and the bottom height adjustment bottom column 42 are also fine-tuned to ensure the height stability of the square tube 1 and the stability of the square tube 1 after flipping.

[0027] When the grinding roller 68 below is grinding, the bent hollow plate 53 will slide to a position close to the weld of the square tube 1 through the lateral sliding shaft 56, thereby lengthening the folding connecting rod 52 and making the position of its air intake groove 55 close to the weld position below the square tube 1. Then the side push box 51 starts to suck air, and absorbs the welding slag generated by grinding into the inside of the bent hollow plate 53. Due to the blocking and filtering work of the filter plate core 54, the welding slag will not enter the inside of the side push box 51, thereby ensuring the adsorption force of the side push box 51, thereby preventing the ground welding slag from falling into the bottom arc shell 43 and affecting the overall deflection work of the grinding equipment 6.

[0028] 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.
