Description

Technical Field

[0001] This invention belongs to the field of automotive processing technology, specifically an automotive pipe welding equipment. Background Technology

[0002] Some internal automotive components are not circular tubes; for example, exhaust pipes are irregularly shaped tubes. The process of assembling these irregularly shaped tubes through welding can create parts with complex shapes and positions, meeting automotive manufacturing requirements. For smaller, irregularly shaped tube components requiring high sealing performance but low load-bearing capacity, welding with soft solder is typically performed on specialized welding equipment.

[0003] During the welding of irregularly shaped pipes, a large amount of welding slag is generated at the pipe joints to ensure the tightness of the connection structure. Therefore, the welding slag needs to be ground after welding to reduce the weight of the pipes, improve their aesthetics and practicality, and prevent slag shedding during use. However, during the grinding process, the grinding force on the pipes will vary because the pipes are not uniform arc structures, which leads to a poorer slag removal effect. Therefore, the welding equipment needs to be improved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: an automotive pipe welding equipment, comprising a square pipe, with clamping devices symmetrically arranged on both sides of the outer surface of the square pipe, a processing device arranged at the bottom of the clamping devices, and a top welding device arranged at the top of the square pipe;

[0005] The top welding equipment includes a fixed top plate, with push slide rods evenly arranged at the bottom of the fixed top plate. A butt arc shell is fixedly connected to the bottom end of the push slide rod. Concentrated arc rods are symmetrically arranged on both sides of the lower surface of the butt arc shell. Monitoring lenses are evenly arranged in the inner cavity of the concentrated arc rods. The concentrated arc rods can monitor the direction of the welding point of the square tube through the monitoring lenses. A control slide plate is slidably connected at the axis of the inner cavity of the butt arc shell. The bottom end of the control slide plate is fixedly connected to the welding end through a push rod.

[0006] The processing equipment includes a fixed base, on which height-adjusting columns are symmetrically arranged on the left and right sides of the upper surface of the fixed base. A bottom arc-shaped shell is fixedly connected to the center of the upper surface of the fixed base by a push rod. The bottom arc-shaped shell has the same structure as the docking arc-shaped shell. After the two are docked, they can form a relatively round shell, which can then wrap the square tube inside. Compensation detectors are symmetrically arranged on both sides of the inner wall of the bottom arc-shaped shell, and a grinding device is installed in the inner cavity of the bottom arc-shaped shell.

[0007] Furthermore, the grinding equipment includes an active slide plate, with a connecting push rod fixedly connected to the top of the active slide plate. A counterweight plate is fixedly connected to the top of the connecting push rod, and an adjusting base is fixedly connected to the top of the counterweight plate. The cylindrical part of the adjusting base can be folded and deformed, and its top is a metal circular plate that will not deform. Torque motors are fixedly connected to both sides of the upper surface of the adjusting base via vertical frame plates. Grinding rollers are fixedly connected to the outer surface of the output shaft of the torque motors. The control slide plate and the active slide plate have the same structure, both having a connecting push rod that penetrates the corresponding arc-shaped shell, and can also actively slide along the inner wall of their arc-shaped shells via side rollers. The outer surface of the active slide plate is slidably connected to the inner cavity of the bottom arc-shaped shell through an arc-shaped groove. The outer surface of the connecting push rod extends to the outside of the bottom arc-shaped shell through an arc-shaped groove. The outer surface of the grinding rollers is pressed against the weld seam of the outer surface of the square tube.

[0008] Furthermore, the top of the inner cavity of the counterweight plate is provided with an arc-shaped groove, and symmetrical side push rods are arranged on the inner wall of the arc-shaped groove. The top of the side push rod is arc-shaped and can be pushed upward. The top of the side push rod is rotatably connected to a docking sleeve. The docking sleeve is in contact with the arc surface of the top of the side push rod through a groove in the inner wall. The docking sleeve is always attached to the metal plane at the top of the inner wall of the adjusting base and can slide along the top of the inner wall of the adjusting base, but will not detach from the top of the inner wall of the adjusting 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 adjusting base through a connecting shaft. The upper surface of the docking sleeve is slidably connected to the top of the inner wall of the adjusting base. The bottom end of the side push rod is slidably connected to the inner cavity of the counterweight plate through a connecting rod. Both sides of the outer surface of the active slide plate are slidably connected to the inner cavity of the bottom arc-shaped shell through rollers.

[0009] Furthermore, the clamping device includes a horizontal support plate, with flat rollers evenly arranged in the inner cavity of the horizontal support plate. Guide side plates are symmetrically arranged on the front and rear sides of the outer surface of the horizontal support plate. A vertical baffle is slidably connected to the upper surface of the guide side plate via a guide groove. A vertical roller is evenly arranged in the inner cavity of the vertical baffle. An absorption device is provided at the bottom of the inner cavity of the horizontal support plate. When clamping a square tube, both the flat rollers and the vertical rollers are in contact with the outer surface of the square tube. The outer surface of the guide side plate is fixedly connected to the side of the horizontal support plate. The outer surface of the flat roller is rotatably connected to the inner cavity of the horizontal support plate via a rotating groove. The bottom end of the vertical baffle is slidably connected to the inner cavity of the guide side plate via a guide groove, and the outer surface of the vertical roller is rotatably connected to the inner cavity of the vertical baffle via a rotating groove.

[0010] Furthermore, the absorption device includes a side push box, the inner cavity of which is uniformly provided with folding connecting rods. A bent hollow plate is fixedly connected to the end of the folding connecting rods away from the side push box. A filter core is filled into the inner cavity of the bent hollow plate near the folding connecting rods. Sliding shafts are symmetrically arranged on the front and rear sides of the outer surface of the bent hollow plate. Air inlet slots are uniformly formed at the end of the inner cavity of the bent hollow plate away from the filter core. The end of the sliding shaft away from the bent hollow plate is slidably connected to the bottom of the inner cavity of a horizontal support plate via a guide rail. The axis at the bottom of the inner cavity of the horizontal support plate is fixedly connected to the top of an adjustable base column. The outer surface of the side push box is fixedly connected to the inner cavity of the horizontal support plate.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. This device can perform welding on the butt joints of irregularly shaped tubes. While welding is being done using the top welding equipment, the bottom grinding equipment can also grind the weld seam below the irregularly shaped tube, thereby cleaning the weld slag at the weld seam. The adjusting base can be tilted to a certain extent under the control of the internal side push rod, allowing the grinding roller to perform grinding work on the weld seam of the tube body in a different direction. By pushing the grinding roller, the grinding force on the tube can be changed, and fine-tuning can be performed on different parts of the square tube to achieve a more uniform grinding effect and avoid the problem of improper grinding force on the square tube.

[0013] 2. During the processing of the square tubes in this device, the welding and slag removal work are carried out simultaneously, thus saving the time consumed by performing each work separately. Moreover, the two processes can complement each other. That is, the grinding equipment can handle the areas with thicker weld material on the square tubes, and the top welding equipment can perform filler welding on the gaps after grinding, thereby compensating for the areas of the square tubes that have been over-ground and ensuring the firmness of the weld points. Through the above-mentioned cyclic processing, the weld seams of the tube body are ensured to be firm, and the remaining weld material is not too thick, making the tube body more aesthetically pleasing.

[0014] 3. The clamping device can fix the placed irregular tubes. When a square tube needs to be flipped, the internal rollers roll and rub the outer surface of the irregular tube to achieve the effect of twisting the irregular tube. When the irregular tube is not twisted, the static friction of the stationary rollers on the outer surface of the irregular tube can fix the tube. The clamping device can fix and automatically flip irregular tubes of different shapes. The vertical baffle can also slide and adjust with the flipping action of the irregular tube to ensure that the irregular tube is fixed by applying extrusion pressure. It can also avoid the problem of extrusion deformation due to excessive clamping force after the tube is flipped.

[0015] 4. During the grinding operation on the lower grinding rollers, the bent hollow plate slides towards the weld seam of the square tube via the side sliding shaft, thereby lengthening the folding connecting rod and bringing the air inlet slot closer to the weld seam below the square tube. Then, the side push box begins to suck in air, absorbing the welding slag produced during grinding into the interior of the bent hollow plate. Due to the blocking and filtering effect of the filter plate core, the welding slag will not enter the interior of the side push box, ensuring the suction force of the side push box and preventing the welding slag from falling into the bottom arc shell and affecting the overall deflection of the grinding equipment.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0025] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: an automotive pipe welding equipment, including a square pipe 1, clamping devices 2 symmetrically arranged on both sides of the outer surface of the square pipe 1, a processing device 4 arranged at the bottom of the clamping device 2, and a top welding device 3 arranged at the top of the square pipe 1.

[0026] The top welding equipment 3 includes a fixed top plate 31. The bottom of the fixed top plate 31 is uniformly provided with push slide rods 32. The bottom end of the push slide rods 32 is fixedly connected to a butt arc shell 33. The two sides of the lower surface of the butt arc shell 33 are symmetrically provided with concentrated arc rods 36. The inner cavity of the concentrated arc rods 36 is uniformly provided with monitoring lenses 37. The concentrated arc rods 36 can monitor the direction of the welding point of the square tube 1 through the monitoring lenses 37. The axis of the inner cavity of the butt arc shell 33 is slidably connected to a control slide plate 34. The bottom end of the control slide plate 34 is fixedly connected to a welding end 35 through a push rod.

[0027] The processing device 4 includes a fixed base 41. Adjustable base columns 42 are symmetrically arranged on the left and right sides of the upper surface of the fixed base 41. A bottom arc-shaped shell 43 is fixedly connected to the axis of the upper surface of the fixed base 41 by a push rod. The bottom arc-shaped shell 43 has the same structure as the docking arc-shaped shell 33. After the two are docked, they can form a relatively round shell, which can then wrap the square tube 1 inside. Compensation detectors 44 are symmetrically arranged on both sides of the inner wall of the bottom arc-shaped shell 43. A grinding device 6 is installed in the inner cavity of the bottom arc-shaped shell 43.

[0028] The grinding equipment 6 includes an active slide plate 61. A connecting push rod 62 is fixedly connected to the top of the active slide plate 61. A counterweight plate 63 is fixedly connected to the top of the connecting push rod 62. An adjusting base 66 is fixedly connected to the top of the counterweight plate 63. The cylindrical part of the adjusting base 66 can be folded and deformed. Its top is a metal circular plate that will not deform. Torque motors 67 are fixedly connected to both sides of the upper surface of the adjusting base 66 via vertical frame plates. Grinding rollers 68 are fixedly connected to the outer surface of the output shaft of the torque motors 67. The control slide plate 34 has the same structure as the active slide plate 61. Both have a connecting push rod 62 that penetrates the corresponding arc-shaped shell and can also actively slide along the inner wall of the arc-shaped shell via side rollers. The outer surface of the active slide plate 61 is slidably connected to the inner cavity of the bottom arc-shaped shell 43 through an arc-shaped groove. The outer surface of the connecting push rod 62 extends to the outside of the bottom arc-shaped shell 43 through an arc-shaped groove. The outer surface of the grinding rollers 68 is pressed against the weld seam of the outer surface of the square tube 1.

[0029] 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 side push rods 64. The top of the side push rod 64 is arc-shaped and can actively push the rod body upward. The top of the side push rod 64 is rotatably connected to a docking sleeve 65. The docking sleeve 65 is in contact with the arc surface of the top of the side push rod 64 through a groove in the inner wall. The docking sleeve 65 is always attached to the metal plane at the top of the inner wall of the adjusting base 66 and can slide along the top of the inner wall of the adjusting base 66, but will not detach from the top of the inner wall of the adjusting base 66. The axis at the top surface of the counterweight plate 63 is rotatably connected to the axis at the top of the inner wall of the adjusting base 66 through a connecting shaft. The upper surface of the docking sleeve 65 is slidably connected to the top of the inner wall of the adjusting base 66. The bottom end of the side push rod 64 is slidably connected to 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 to the inner cavity of the bottom arc-shaped shell 43 through rollers.

[0030] When using this device to weld square tubes 1, place the two square tubes 1 to be welded on the clamping devices 2 on both sides, and then adjust the top height of the adjustable base columns 42 on both sides so that the square tubes 1 on both sides are aligned and joined together, ready to carry out the welding work.

[0031] The upper and lower push rods 32 respectively advance the mating arc-shaped shell 33 and the bottom arc-shaped shell 43, thereby causing the mating arc-shaped shell 33 and the bottom arc-shaped shell 43 to engage and mate together, enclosing the square tube 1 inside. Figure 1As shown, the upper welding end 35 then automatically welds the weld seam between the two square tubes 1. During the welding process, the control slide 34 slides along the inner cavity of the mating arc shell 33, thereby driving the bottom welding end 35 to deflect synchronously along the inner wall of the mating arc shell 33. However, since the mating arc shell 33 is only a half-section arc shell, the actual deflection range of the welding end 35 is limited, and it is impossible to weld the other side of the square tube 1. At this time, the clamping devices 2 on both sides need to assist in the process, so as to flip the square tube 1 over and then achieve the full welding work at the joint of the square tube 1.

[0032] During welding, due to the special shape of the irregular tube, in order to ensure the strength of the weld at the joint of the tube body, it is necessary to use the monitoring lens 37 of the arc rod 36 to monitor the weld position and perform appropriate repair welding to check for omissions and make up for deficiencies. After the joint of the square tube 1 is welded, the area covered by the welding slag at the weld will definitely be larger than the actual weld area. Therefore, it is necessary to deal with this slag. 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.

[0033] After the active slide plate 61 pushes the counterweight plate 63 close to the square tube 1 via the connecting push rod 62, the grinding roller 68, which rotates at the top height, grinds the square tube 1. Meanwhile, the side push rods 64 located on both sides of the inner wall of the adjustment base 66 tilt the top part of the adjustment base 66 by raising one side and shortening the other side, thereby changing the grinding focus range of the grinding roller 68. This applies different squeezing forces and different grinding angles to the outer surface of the square tube 1, thus grinding away the thicker welding slag.

[0034] Because the top welding equipment 3 will perform multiple monitoring and repair welding operations on the weld position of the square tube 1, the weld after grinding will be scanned again by the monitoring lens 37 directly above after being flipped. When it is detected that the weld joint is thin due to excessive grinding, the top welding equipment 3 will perform repair welding to reinforce this weak part. At the same time, the grinding equipment 6 below is still performing grinding work, and the excess welding slag produced by the welding of the top welding equipment 3 above is also processed multiple times. After repeating the above work for a period of time, the weld 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 equipment 2.

[0035] Example 2, please refer to Figures 1-7This invention provides a technical solution: Based on embodiment 1, the clamping device 2 includes a horizontal support plate 21. Flat rollers 22 are uniformly arranged in the inner cavity of the horizontal support plate 21. Guide side plates 23 are symmetrically arranged on the front and rear sides of the outer surface of the horizontal support plate 21. A vertical baffle 24 is slidably connected to the upper surface of the guide side plate 23 via a guide groove. A vertical roller 25 is uniformly arranged in the inner cavity of the vertical baffle 24. An absorption device 5 is arranged at the bottom of the inner cavity of the horizontal support plate 21. When clamping the square tube 1, both the flat rollers 22 and the vertical rollers 25 are 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 via a rotating groove. The bottom end of the vertical baffle 24 is slidably connected to the inner cavity of the guide side plate 23 via a guide groove, and the outer surface of the vertical roller 25 is rotatably connected to the inner cavity of the vertical baffle 24 via a rotating groove.

[0036] The absorption device 5 includes a side push box 51. Folding connecting rods 52 are evenly arranged within the inner cavity of the side push box 51. A bent hollow plate 53 is fixedly connected to the end of the folding connecting rods 52 away from the side push box 51. A filter core 54 is filled into the inner cavity of the bent hollow plate 53 near the folding connecting rods 52. Sliding shafts 56 are symmetrically arranged on the front and rear sides of the outer surface of the bent hollow plate 53. Air inlet slots 55 are evenly formed at the end of the inner cavity of the bent hollow plate 53 away from the filter core 54. 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 via a guide rail. The axis at the bottom of the inner cavity of the horizontal support plate 21 is fixedly connected to the top of the height adjustment column 42. The outer surface of the side push box 51 is fixedly connected to the inner cavity of the horizontal support plate 21.

[0037] 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, while the vertical baffles 24 on both sides will press along the sliding groove of the guide side plate 23 towards the side of the square tube 1, thereby clamping the side of the square tube 1 by the vertical roller 25. When flipping the square tube 1, the flat roller 22 and the vertical roller 25 will drive the square tube 1 clamped inside to rotate by actively rotating. At the same time, the vertical baffles 24 on both sides and the bottom height adjustment column 42 are also finely adjusted to ensure the stability of the height of the square tube 1 and the stability of the square tube 1 after flipping.

[0038] When the grinding roller 68 performs grinding, the bent hollow plate 53 slides towards the weld of the square tube 1 via the sliding shaft 56 on the side, thereby lengthening the folding connecting rod 52 and bringing the position of its air inlet groove 55 closer to the weld below the square tube 1. Then, the side push box 51 starts to suck in air, absorbing the welding slag produced by grinding into the interior 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 interior of the side push box 51, ensuring the suction force of the side push box 51, thereby preventing the welding slag from falling into the bottom arc shell 43 and affecting the overall deflection of the grinding equipment 6.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort 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, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
