Description

Technical Field

[0001] The invention belongs to the field of automobile parts processing, in particular to a welding tool for automobile parts processing. Background Art

[0002] As the foundation of the automotive industry, auto parts are essential for its sustained and healthy development. This is especially true with the current vigorous and dynamic development of independent development and innovation within the automotive industry, which requires a robust parts system to support it. Independent vehicle brands and technological innovation rely on parts as a foundation, and independent innovation in parts, in turn, strongly drives the development of the entire vehicle industry. These processes influence and interact with each other, and welding is an essential step in the processing of automotive parts. Welding, also known as fusion, is a manufacturing process and technology that uses heat, high temperature, or high pressure to join metals or other thermoplastic materials, such as plastics. Modern welding uses a variety of energy sources, including gas flame, arc, laser, electron beam, friction, and ultrasonic waves. The welding of automotive parts often requires welding multiple pipes to form exhaust pipes.

[0003] The existing technology is not convenient for processing the contact surface of the two sections of pipes when welding them. If there are burrs or other debris on the contact surface of the two sections of pipes, the pipe joint gap will be uneven during welding. The arc cannot evenly heat the contact surface during welding, and some areas do not reach the melting temperature, resulting in incomplete welding or incomplete fusion. Secondly, in order to ensure the sealing of the welding, it is necessary to perform circumferential welding on a circle of the pipe. The existing technology is not convenient for adjusting the position of the pipe during the welding process, resulting in a relatively single welding position. If the pipe is rotated manually, it cannot be guaranteed that the two sections of the pipe are always aligned during the welding process. When the pipe is misaligned, the welding point is very likely to leak. In addition, it is not convenient to inspect the welding point of the two sections of the pipe after welding, and it is impossible to judge whether the welding is firm in time. If a cold weld occurs, it will greatly affect the quality of the welded pipe.

[0004] To this end, the present invention provides a welding tool for processing automobile parts. Summary of the Invention

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that the existing technology is not convenient for processing the contact surface of the two pipes when welding two pipes, if there are burrs and other debris on the contact surface of the two pipes, the pipe joint gap will be uneven during welding, and the arc cannot evenly heat the contact surface during welding. Some areas do not reach the melting temperature, resulting in incomplete welding or incomplete fusion. Secondly, in order to ensure the sealing of the welding, it is necessary to perform circumferential welding on a circle of the pipe. The existing technology is not convenient for adjusting the position of the pipe during welding, resulting in a relatively single welding position.

[0016] The beneficial effects of the present invention are as follows: 1. The welding tool for processing automobile parts described in the present invention controls two sections of pipes by means of two first electric telescopic rods, one of which is clamped and the other is in a relaxed state. The motor controls the rotation of the first bevel gear, which drives the rotation of the two second bevel gears, which in turn drives the rotation of the two first straight gears, which in turn drives the rotation of the two gear rings, thereby rotating the two clamping platforms. On the basis of driving the rotation of one pipe, the other pipe is caused to rotate in the same direction.

[0017] 2. The welding tool for processing automobile parts described in the present invention can increase the longitudinal friction between the pipeline and the pulley by arranging a rubber ring on the outer wall of the pulley. After the pipeline is firmly clamped by a plurality of clamping plates, the pipeline can be driven to rotate along with the rotation of the clamping platform. After the welding of the two sections of pipeline is completed, the two first electric telescopic rods are controlled so that the pipelines in the two clamping platforms are firmly clamped. At this time, the motor is started again to drive the first bevel gear to rotate, so that the two second bevel gears rotate at the same time. Since the two second bevel gears rotate in opposite directions, the two sections of pipeline in the two clamping platforms rotate one forward and the other backward. At this time, the welding position will be subjected to torque load, causing shear stress and torsional stress in the weld. If the weld is not fully penetrated, it will be obviously deformed or cracked under the action of torque. It is necessary to repair the welding of the two sections of pipeline in time to improve the firmness of the pipeline after welding.

[0018] 3. The welding tool for processing automobile parts described in the present invention is configured to place several first grinding blocks in a state of being close to each other by means of several second springs. After the pipe is inserted into the clamping table, the end face of the pipe is pressed against the several first grinding blocks. At this time, the clamping table is controlled to rotate by a motor, which can drive the several first grinding blocks to rotate, thereby grinding the end face of the pipe to remove burrs on the end face of the pipe and avoid affecting the splicing of two sections of the pipe during welding. When the several sliders are controlled to approach each other to clamp the pipe, the several first grinding blocks are opened by the linkage assembly to facilitate the passage of the pipe.

[0019] 4. The welding tool for processing automotive parts described in the present invention controls the co-directional rotation of two sections of welded pipes. A second electric telescopic rod controls a second grinding block to press against the pipes. As the two sections of pipes rotate in the same direction, excess weld excess height at the weld joint between the two sections of pipes can be ground. After the weld excess height is ground, it is convenient to observe whether there is any leakage at the weld joint between the two sections of pipes. The arc-shaped surface at the top of the baffle guides debris to be concentrated in the concave surface at the top of the baffle, making the debris easier to clean. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the second support plate 12 is fixedly connected to a fixed ring 13, and the outer wall of the fixed ring 13 is rotatably connected to a second rotating ring 14. The outer wall of the second rotating ring 14 is equidistantly fixedly connected to a plurality of push rods 15, which are slidably connected to the clamping table 7 and cooperate with the inclined groove 16. The inner wall of the clamping plate 9 is equidistantly fixedly connected to a plurality of first rotating shafts 17, and the outer wall of the first rotating shaft 17 is rotatably connected to a pulley 18. The rotating assembly includes two third support plates 20, which are symmetrically fixedly mounted on the bottom At the top of the seat 1, the inner walls of the two third support plates 20 are rotatably connected to the second rotating shaft 23, one end of the second rotating shaft 23 is fixedly connected to the first spur gear 25, the outer wall of the clamping platform 7 is fixedly connected to the gear ring 26, the first spur gear 25 is meshed with the gear ring 26, the other end of the second rotating shaft 23 is fixedly connected to the second bevel gear 24, the top of the base 1 is fixedly connected to the motor 21, the output end of the motor 21 is fixedly connected to the first bevel gear 22, and the two second bevel gears 24 are meshed with the first bevel gear 22.

[0024] Through the above technical solution, by arranging a number of pulleys 18 on the clamping plate 9, it is convenient to insert the two sections of pipe into the two clamping platforms 7 respectively, start the two first electric telescopic rods 10, and drive the two fixed rings 13 to approach the two clamping platforms 7 respectively. When the fixed ring 13 approaches the clamping platform 7, it drives the second rotating ring 14 to approach the clamping platform 7, so that the several push rods 15 are all inserted into the clamping platform 7. While the several push rods 15 move, they respectively press against the inclined surfaces of the outer walls of the several sliders 8. Under the pressure of the several push rods 15, the several sliders 8 are brought close to each other, driving the several clamping plates 9 to approach each other, clamping and fixing the pipes in the clamping platform 7, thereby fixing the two sections of pipe together, welding the two sections of pipe by the welding gun 4, and after welding the two sections of pipe at a point, controlling one of the first electric Move the telescopic rod 10 to move the top rod 15 inside the corresponding clamping platform 7 out, thereby adjusting the tightness of the clamping of the clamping plate 9 on the pipe, and keeping the pipe in the clamping platform 7 able to rotate. At this time, one pipe is clamped and the other pipe is loosened. Start the motor 21 to drive the first bevel gear 22 to rotate, so that the two second bevel gears 24 rotate, drive the two second rotating shafts 23 to rotate, and drive the two first straight gears 25 to rotate, and drive the two gear rings 26 to rotate, thereby rotating the two clamping platforms 7. On the basis of driving one pipe to rotate, the other pipe follows and rotates in the same direction. Under the limit of several clamping plates 9, the pipe can rotate stably between several clamping plates 9, thereby facilitating circumferential welding of the joints of the two pipe sections, and enabling the two pipe sections to rotate smoothly, thereby improving the precision of welding.

[0025] Specifically, a plurality of rubber rings 19 are fixedly connected to the outer wall of the pulley 18 at equal intervals.

[0026] Through the above technical solution, the longitudinal friction between the pipe and the pulley 18 can be increased by providing the rubber ring 19 on the outer wall of the pulley 18. After the pipe is firmly clamped by several clamping plates 9, the pipe can be driven to rotate with the rotation of the clamping platform 7. After the welding of the two sections of the pipe is completed, the motor 21 is turned off and the two first electric telescopic rods 10 are controlled so that the pipes in the two clamping platforms 7 are firmly clamped. At this time, the motor 21 is started again to drive the first bevel gear 22 to rotate, so that the two second bevel gears 24 rotate at the same time. Since the two second bevel gears 24 rotate in opposite directions, the two clamping platforms 7 are driven to rotate forward and backward, so that the two sections of the pipe in the two clamping platforms 7 rotate forward and backward. At this time, the welding position will be subjected to torque load, causing shear stress and torsional stress to be generated in the weld. If the welding is not fully penetrated, it will be obviously deformed or cracked under the action of torque. It is necessary to repair the two sections of the pipe in time to improve the firmness of the pipe after welding.

[0027] Specifically, the inner wall of the clamping table 7 is equidistantly and slidingly connected to several slides 27, the outer wall of the slide 27 is fixedly connected to a connecting frame 28, one side of the connecting frame 28 is fixedly connected to a mounting plate 29, the outer wall of the mounting plate 29 is fixedly connected to a first grinding block 30, and a linkage assembly is provided between the slide 27 and the slider 8; the linkage assembly includes several third rotating shafts 31, and several third rotating shafts 31 are equidistantly and fixedly connected to the inside of the clamping table 7, the third rotating shaft 31 is located between the slide 27 and the slider 8, the outer wall of the third rotating shaft 31 is rotatably connected to the second spur gear 32, the outer wall of the slider 8 is fixedly connected to the first rack 33, the outer wall of the slide 27 is fixedly connected to the second rack 34, the first rack 33 and the second rack 34 are both meshed with the second spur gear 32, one side of the slide 27 is fixedly connected to a second spring 44, and the second spring 44 is fixedly connected to the clamping table 7.

[0028] Through the above technical solution, by setting up several second springs 44, several first grinding blocks 30 are placed in a state of being close to each other. After the pipe is inserted into the clamping table 7, the end face of the pipe is pressed against the several first grinding blocks 30. At this time, the motor 21 controls the rotation of the clamping table 7, which can drive the several first grinding blocks 30 to rotate, grind the end face of the pipe, remove burrs on the end face of the pipe, and avoid affecting the splicing of the two sections of the pipe during welding. When controlling the several sliders 8 to approach each other to clamp the pipe, as the slider 8 moves, the first rack 33 is driven to move, the second spur gear 32 is moved, and the slide plate 27 is driven to move toward the inside of the clamping table 7, pressing the second spring 44, thereby making the several first grinding blocks 30 move away from each other and open, so as to facilitate the passage of the pipe.

[0029] Specifically, a baffle 41 is fixedly connected to the top of the base 1 and above the motor 21. The top of the baffle 41 is set as an arc surface, and two groups of side panels 42 are symmetrically fixedly connected to the arc surface at the top of the baffle 41; a guide ring 43 is fixedly connected to the outer wall of the clamping platform 7, and the inner wall of the guide ring 43 is set as an annular inclined surface.

[0030] Through the above technical solution, the baffle 41 is set to block the debris generated by the pipe grinding, preventing the debris from falling on the motor 21. The debris ground by the first grinding block 30 falls on the baffle 41 along the guidance of the guide ring 43, and then is guided by the curved surface at the top of the baffle 41 to concentrate the debris in the concave surface at the top of the baffle 41, making it easy to clean the debris.

[0031] Specifically, the inner wall of the baffle 41 is fixedly connected to the second electric telescopic rod 35, the output end of the second electric telescopic rod 35 is fixedly connected to the fixed plate 36, the inner wall of the fixed plate 36 is symmetrically slidably connected to two sliding shafts 37, the bottoms of the two sliding shafts 37 are fixedly connected to the limiting blocks 38, the tops of the two sliding shafts 37 are fixedly connected to the second grinding blocks 40, the outer walls of the two sliding shafts 37 are sleeved with first springs 39, the bottom of the first spring 39 is fixedly connected to the fixed plate 36, and the top of the first spring 39 is fixedly connected to the second grinding block 40.

[0032] Through the above technical solution, after the welding of the two sections of the pipe is completed, the second electric telescopic rod 35 controls the fixing plate 36 to move upward, so that the second grinding block 40 moves upward. The first spring 39 is provided so that the second grinding block 40 can be pressed against the welding point of the two sections of the pipe. At this time, the fixation of one section of the pipe is released, and the two sections of the pipe are rotated in the same direction on the basis of controlling the rotation of the other section of the pipe. With the cooperation of the second grinding block 40, the excess weld height on the welding point of the two sections of the pipe can be ground. After the weld height is ground, it is convenient to observe whether there is any leakage in the welding point of the two sections of the pipe.

[0033] When in use, by setting a plurality of pulleys 18 on the clamping plate 9, it is convenient to insert the two sections of pipe into the two clamping platforms 7 respectively, and by setting a plurality of second springs 44, the plurality of first grinding blocks 30 are in a state of being close to each other. After the pipe is inserted into the clamping platform 7, the end face of the pipe is pressed against the plurality of first grinding blocks 30. At this time, the clamping platform 7 is controlled to rotate by the motor 21, which can drive the plurality of first grinding blocks 30 to rotate, grind the end face of the pipe, remove burrs on the end face of the pipe, and avoid affecting the splicing of the two sections of pipe during welding. The two first electric telescopic rods 10 are started to drive the two fixed rings 13 to approach the two clamping platforms 7 respectively. When the fixed ring 13 approaches the clamping platform 7, it drives the second rotating ring 14 to approach the clamping platform 7, so that the plurality of ejector rods 15 are all inserted into the clamping table 7, and several push rods 15 move while pressing against the inclined surfaces of the outer walls of several sliders 8. Under the extrusion of several push rods 15, several sliders 8 are moved close to each other, driving several clamping plates 9 to move close to each other, clamping and fixing the pipes in the clamping table 7, thereby fixing the two sections of pipes together. When controlling the several sliders 8 to approach each other to clamp the pipes, as the sliders 8 move, the first rack 33 is driven to move, the second spur gear 32 is moved, and the slide plate 27 is driven to move toward the inside of the clamping table 7, pressing the second spring 44, thereby making the several first grinding blocks 30 move away from each other and open, so that the pipes can pass through. The two sections of the pipes are welded by the welding gun 4. After welding a point on the two sections of the pipes, one of the first electric The telescopic rod 10 moves out the top rod 15 inside the corresponding clamping platform 7, thereby adjusting the tightness of the clamping plate 9 on the pipe, keeping the pipe in the clamping platform 7 able to rotate. At this time, one pipe is clamped and the other pipe is loosened. The motor 21 is started to drive the first bevel gear 22 to rotate, which drives the two second bevel gears 24 to rotate, drives the two second rotating shafts 23 to rotate, and drives the two first straight gears 25 to rotate, which drives the two gear rings 26 to rotate, thereby rotating the two clamping platforms 7. On the basis of driving one pipe to rotate, the other pipe follows and rotates in the same direction. Under the limit of several clamping plates 9, the pipe can rotate stably between several clamping plates 9, thereby facilitating the circumferential welding of the joints of the two pipe sections and enabling the two pipe sections to rotate smoothly, improving the working efficiency. In order to improve the precision of welding, the longitudinal friction between the pipe and the pulley 18 can be increased by setting the rubber ring 19 on the outer wall of the pulley 18. After the pipe is firmly clamped by several clamping plates 9, the pipe can be driven to rotate with the rotation of the clamping platform 7. After the welding of the two pipe sections is completed, the fixing plate 36 is controlled to move upward by the second electric telescopic rod 35, so that the second grinding block 40 moves upward. The second grinding block 40 can be pressed against the welding point of the two pipe sections by the first spring 39. At this time, the fixation of one of the pipe sections is released, and the two pipe sections are rotated in the same direction on the basis of controlling the rotation of the other pipe section. With the help of the second grinding block 40, the excess weld height on the welding point of the two pipe sections can be ground. After the weld height is ground,It is convenient to observe whether there is any leakage at the welding of the two sections of pipes, and then turn off the motor 21, control the two first electric telescopic rods 10, so that the pipes in the two clamping platforms 7 are firmly clamped, and then start the motor 21 again, driving the first bevel gear 22 to rotate, so that the two second bevel gears 24 rotate at the same time. Since the two second bevel gears 24 rotate in opposite directions, the two clamping platforms 7 are driven to rotate one forward and one backward, so that the two sections of pipes in the two clamping platforms 7 rotate one forward and one backward. At this time, the welding position will be subjected to torque load, causing shear stress and torsional stress to be generated in the weld. If there is incomplete penetration in the welding, it will be obviously deformed or cracked under the action of torque. It is necessary to repair the two sections of pipes in time to improve the firmness of the pipe welding. The baffle 41 provided can block the debris generated by pipe grinding to prevent the debris from falling on the motor 21. The debris ground by the first grinding block 30 falls on the baffle 41 along the guide ring 43, and then guided by the arc-shaped surface at the top of the baffle 41, the debris is concentrated in the concave surface at the top of the baffle 41, so that the debris is easy to clean. ,
