Description

Technical Field

[0001] The invention belongs to the technical field of exhaust pipe welding, and in particular relates to a motorcycle exhaust pipe welding device. Background Art

[0002] The motorcycle exhaust pipe is an important component connecting the engine and the exhaust system. Its design and performance directly affect the vehicle's power, fuel efficiency and emission level. The exhaust pipe guides the exhaust gas generated by combustion into the atmosphere when the engine is working, and the engine's performance can be adjusted by designing and adjusting the structure of the exhaust pipe. The basic principle of the exhaust pipe is to use the momentum and pressure difference of the exhaust gas to produce a negative pressure effect through the tortuosity and expansion design inside the exhaust pipe, thereby helping to improve the engine's air extraction efficiency, promote the entry of fresh air into the combustion chamber, improve combustion efficiency, and thus improve power output and fuel efficiency. In addition to its basic functions, the exhaust pipe also plays an important role in the design of motorcycles in terms of aesthetics and sound adjustment. Through the shape design and material selection of the exhaust pipe, a unique appearance style can be added to the motorcycle. At the same time, the internal structure and silencer of the exhaust pipe can adjust the vehicle's exhaust sound to meet the relevant regulatory requirements or meet the personalized needs of the owner. In general, the motorcycle exhaust pipe is not only an important channel for the engine to discharge exhaust gas, but also an important part of engine performance adjustment and vehicle aesthetics and sound adjustment.

[0003] When welding a motorcycle exhaust pipe, a welding gun needs to be used to weld part of the short pipe, and the short pipe is rotated to weld all around, but there are also shortcomings. The existing motorcycle exhaust pipe welding device only clamps one end when welding the motorcycle exhaust pipe, which causes the welding joint to be easily misaligned under the squeezing of the welding gun during welding, resulting in the exhaust pipe needing to be reworked twice, thereby wasting a lot of time and resource consumption. At the same time, the motorcycle exhaust pipe before production contains other impurities and burrs before welding, resulting in the exhaust pipe after welding being unstable. At the same time, the welding joint of the motorcycle exhaust pipe after welding is relatively rough, which can easily scratch the operator, causing certain safety hazards, thereby greatly affecting the subsequent processing effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a motorcycle exhaust pipe welding device.

[0005] The technical solution adopted to solve the above technical problems is: a motorcycle exhaust pipe welding device, comprising a main body, a bottom frame is fixedly connected to the bottom of the main body, a bottom plate is fixedly connected to the bottom of the bottom frame, and a pipe opening is opened inside the main body; A clamping mechanism is installed on the top of one side of the main body, two support rods are fixedly connected to one side of the top of the base frame, and a direction-changing clamping mechanism is installed between the two support rods; A rotating mechanism is installed on the other side of the main body, a fixed plate is fixedly connected to one side of the rotating mechanism, a driving mechanism is installed on the top of one side of the fixed plate, and an alternating mechanism is installed on the bottom of the driving mechanism.

[0006] Furthermore, the clamping mechanism includes a first motor fixedly connected to the top of one side of the main body, the output end of the first motor is fixedly connected to the first driving shaft, the outer wall of the first driving shaft is fixedly connected to the first synchronous wheel, the outer wall of the first synchronous wheel is rotatably connected to the first synchronous belt, the other end of the first synchronous belt is rotatably connected to the second synchronous wheel, a plurality of first fixed seats are fixed to one side of the main body, the bottom of the first synchronous wheel and the second synchronous wheel are both fixedly connected to a two-way threaded rod, both sides of the outer walls of the two two-way threaded rods are rotatably connected to sliding seats, an arc clamp is fixedly connected between each two of the sliding seats, the interior of each two of the first fixed seats is rotatably connected to one of the two-way threaded rods, and the two arc clamps are respectively located at the upper and lower parts of the pipe mouth.

[0007] Through the above technical solution, when in use, the motorcycle exhaust pipe is inserted from the pipe mouth, and the middle end is clamped by the clamping mechanism to avoid rotation during welding. Specifically, when the motorcycle exhaust pipe is placed in the main body, the first motor on the top of one side of the main body is started to drive the first drive shaft to rotate. Since the first synchronous wheel and the second synchronous wheel are connected under the first synchronous belt transmission, the two bidirectional threaded rods rotate, and then the multiple first fixed seats on the two bidirectional threaded rods move thereon respectively, thereby driving the two arc clamps to clamp the motorcycle exhaust pipe, so that the middle end of the motorcycle exhaust pipe is clamped and waits for subsequent processing.

[0008] Furthermore, the direction-changing clamp mechanism includes a clamp seat rotatably connected to the top of the base plate, a hydraulic cylinder is fixedly connected to the inside of the clamp seat, a first connecting plate is fixedly connected to the piston end of the hydraulic cylinder, side plates are fixedly connected to the two sides of the clamp seat, the tops of the two side plates are fixedly connected to the second connecting plates, the second connecting plates are rotatably connected to the clamp bodies on both sides, the first connecting plates are rotatably connected to the two sides of the first connecting plate, the bottom of the clamp seat is fixedly connected to the steering column, the front and rear ends of the outer wall of the steering column are fixedly connected to the first fixing bolts, the outer walls of the two first fixing bolts are fixedly connected to the springs, the other ends of the two springs are fixedly connected to the second fixing bolts, the other ends of the two connecting rods are rotatably connected to the corresponding clamp bodies respectively, the steering column runs through the inside of the base plate, and the top of the second fixing bolt is fixedly connected to the base plate.

[0009] Through the above technical scheme, when in use, when the exhaust pipe passes through the main body, the head end will reach the redirecting clamp mechanism, and when the exhaust pipe in different bending directions enters, it can be clamped, which greatly improves the stability of the exhaust pipe during welding. Specifically, when the head end of the exhaust pipe reaches the redirecting clamp mechanism, the hydraulic cylinder inside the clamp seat is started to push the first connecting plate upward. Since the first connecting plate and the two sides of the clamp body are respectively connected by two connecting rods, when the first connecting plate moves upward, the two connecting rods support the clamp bodies on both sides of the second connecting plate upward until the head end of the exhaust pipe is clamped. After that, after the top of the redirecting clamp mechanism is subjected to force, the steering column rotates in the direction of the exhaust pipe, which will pull a spring on the outer wall of the steering column to ensure that the redirecting clamp mechanism can be reset after being loosened, thereby ensuring that the exhaust pipe will not be misaligned during and after welding.

[0010] Furthermore, the rotating mechanism includes a second motor fixedly connected to the bottom of one side of the main body, the output end of the second motor is fixedly connected to a second driving shaft, the outer wall of the second driving shaft is fixedly connected to a third synchronous wheel, the outer wall of the third synchronous wheel is rotatably connected to a second synchronous belt, the other end of the second synchronous belt is rotatably connected to a synchronous ring, and the other side of the main body is rotatably connected to multiple rotating shafts, the outer walls of the multiple rotating shafts are all fixedly connected to limiting wheels, an inner groove is opened in the synchronous ring, the second driving shaft runs through the interior of the main body, and the outer walls of the multiple limiting wheels are rotatably connected to the inner groove.

[0011] Through the above technical solution, during use, when the exhaust pipe is clamped, the rotating mechanism is used to drive the welding device to weld the exhaust pipe. Specifically, the second motor at the bottom of one side of the starter body drives the third synchronous wheel on the outer wall of the second drive shaft to rotate, and the limiting wheels on the outer walls of multiple rotating shafts are used to fix the synchronous ring for rotation. When the second synchronous belt is connected with the synchronous ring and the third synchronous wheel in rotation, the rotating mechanism can operate normally.

[0012] Furthermore, the driving mechanism includes a movable block rotatably connected to the surface of the fixed plate, the front end of the movable block is fixedly connected to a third motor, the output end of the third motor is fixedly connected to a one-way threaded rod, and the outer wall of the one-way threaded rod is rotatably connected to a movable seat.

[0013] Through the above technical solution, during use, after the exhaust pipe is clamped and adjusted, the third motor at the front end of the movable block is started to drive the one-way threaded rod to rotate, so that the movable seat can move smoothly on the one-way threaded rod, thereby realizing the welding and grinding of the exhaust pipe, greatly improving the functionality of the welding device.

[0014] Furthermore, the alternating mechanism includes a connecting body rotatably connected to the inside of the movable seat, the other side of the main body is rotatably connected to a first ring body, one side of the first ring body is fixedly connected to a second ring body through a support body, the other side of the main body is fixedly connected to two cylindrical seats, one side of the two cylindrical seats is rotatably connected to sliding rods, the outer walls of the two sliding rods are slidably connected to sliding sleeves, two movable grooves are provided inside the first ring body, the other end of one of the sliding rods is fixedly connected to a grinder, and the other end of the other sliding rod is fixedly connected to a welding gun, a limiting groove is provided on the surface of the fixed plate, the two cylindrical seats are respectively located at two ends of the first ring body, the two sliding sleeves are fixedly connected to the first ring body and the second ring body, and the other side of the first ring body is rotatably connected to the limiting groove.

[0015] Through the above technical scheme, when in use, after the exhaust pipe is adjusted, an alternating mechanism is used to first grind it before welding, and then it is adjusted and welded. After welding is completed, it is polished again to ensure its aesthetics. Specifically, as the movable seat moves, the connector is driven, and then the first ring body and the second ring body rotate. Since the two sliding sleeves are fixed between the first ring body and the second ring body, the two sliding sleeves move on the corresponding sliding rods respectively. When rotating in the opposite direction, one of the sliding sleeves moves upward on the corresponding sliding rod, and then the grinder moves to the middle end to grind the exhaust pipe. The other sliding sleeve moves downward on the corresponding sliding rod, and the welding gun will move to the outside, and then move in one of the movable grooves, and then during welding, it moves forward, thereby realizing the entire grinding and welding work.

[0016] The beneficial effects of the present invention are as follows: (1) By designing a clamping mechanism, a direction-changing clamping mechanism, a rotating mechanism, a driving mechanism and an alternating mechanism, the present invention can fix the exhaust pipe of different lengths and bending shapes forward and backward when the motorcycle exhaust pipe enters the welding device, thereby ensuring that the welding joint will not be offset during the welding process, avoiding rework, and being able to grind the exhaust pipe forward and backward, so that the exhaust pipe welding can be more stable and maintain a certain aesthetics; (2) By designing a clamping mechanism and a direction-changing clamping mechanism, the present invention can weld exhaust pipes of different lengths and shapes. At both ends of the welding joint, by linear clamping and clamping in different directions, the exhaust pipe will not be offset due to the instability of the welding joint during welding, thereby greatly improving the stability of welding; (3) By designing a rotating mechanism, a driving mechanism and an alternating mechanism, the present invention can grind the motorcycle exhaust pipe before welding to remove burrs and other substances at the welding joint. At the same time, after welding, the motorcycle exhaust pipe is grinded to ensure that the welding part of the motorcycle exhaust pipe has a certain aesthetics, thereby greatly improving the performance of the welding device.

The two arc clamps 509 are respectively located at the upper and lower parts of the pipe mouth 4. When in use, the motorcycle exhaust pipe is inserted from the pipe mouth 4, and the middle end is clamped by the clamping mechanism 5 to avoid rotation during welding. Specifically, when the motorcycle exhaust pipe is placed in the main body 1, the first motor 501 on the top of one side of the main body 1 is started to drive the first drive shaft 502 to rotate. Since the first synchronous wheel 503 and the second synchronous wheel 505 are rotatably connected with the first synchronous belt 504, the two two-way threaded rods 507 are rotated, and then the multiple first fixed seats 506 on the two two-way threaded rods 507 are respectively moved thereon, thereby driving the two arc clamps 509 to clamp the motorcycle exhaust pipe, so that the middle end of the motorcycle exhaust pipe is clamped and waits for subsequent processing.

Specifically, when the head end of the exhaust pipe reaches the redirecting clamping mechanism 7, the hydraulic cylinder 702 inside the clamp seat 701 is started to push the first connecting plate 703 upward. Since the first connecting plate 703 and the clamping body 706 are respectively connected by two connecting rods 707 on both sides, when the first connecting plate 703 moves upward, the two connecting rods 707 support the clamping bodies 706 on both sides of the second connecting plate 705 upward until the head end of the exhaust pipe is clamped.

[0022] like Fig.11 and Fig.12The other side of the main body 1 is equipped with a rotating mechanism 8, which includes a second motor 801 fixedly connected to the bottom of one side of the main body 1, a second drive shaft 802 fixedly connected to the output end of the second motor 801, a third synchronous wheel 803 fixedly connected to the outer wall of the second drive shaft 802, a second synchronous belt 804 rotatably connected to the outer wall of the third synchronous wheel 803, a synchronous ring 805 rotatably connected to the other end of the second synchronous belt 804, a plurality of rotating shafts 806 rotatably connected to the other side of the main body 1, the outer walls of the plurality of rotating shafts 806 are all fixedly connected to the limiting wheel 807, and an inner groove 80 is provided inside the synchronous ring 805. 8. The second drive shaft 802 runs through the inside of the main body 1, and the outer walls of multiple limiting wheels 807 are rotatably connected to the inner groove 808. When in use, when the exhaust pipe is clamped, the rotating mechanism 8 is used to drive the welding device to weld the exhaust pipe. Specifically, the second motor 801 at the bottom of one side of the main body 1 is started to drive the third synchronous wheel 803 on the outer wall of the second drive shaft 802 to rotate, and the limiting wheels 807 on the outer walls of multiple rotating shafts 806 are used to fix the synchronous ring 805 for rotation. Under the rotation connection between the second synchronous belt 804, the synchronous ring 805 and the third synchronous wheel 803, the rotating mechanism 8 operates normally.

[0023] like Figure 8 , Fig. 9 and Fig.10 As shown, a fixed plate 9 is fixedly connected to one side of the rotating mechanism 8, and a driving mechanism 10 is installed on the top of one side of the fixed plate 9. The driving mechanism 10 includes a movable block 1001 rotatably connected to the surface of the fixed plate 9, a third motor 1002 is fixedly connected to the front end of the movable block 1001, a one-way threaded rod 1003 is fixedly connected to the output end of the third motor 1002, and a movable seat 1004 is rotatably connected to the outer wall of the one-way threaded rod 1003. When in use, after the exhaust pipe is clamped and adjusted, the third motor 1002 at the front end of the movable block 1001 is started to drive the one-way threaded rod 1003 to rotate, so that the movable seat 1004 can move smoothly on the one-way threaded rod 1003, thereby realizing the welding and grinding of the exhaust pipe, which greatly improves the functionality of the welding device.

[0024] like Figure 8 , Fig. 9 and Fig.10As shown, an alternating mechanism 11 is installed at the bottom of the driving mechanism 10, and the alternating mechanism 11 includes a connecting body 1101 rotatably connected to the inside of the movable seat 1004, a first ring body 1102 is rotatably connected to the other side of the main body 1, a second ring body 1103 is fixedly connected to one side of the first ring body 1102 through a supporting body, and two cylindrical seats 1104 are fixedly connected to the other side of the main body 1, and sliding rods 1105 are rotatably connected to one side of the two cylindrical seats 1104, and the outer walls of the two sliding rods 1105 are slidably connected to sliding sleeves 1106, two movable grooves 1107 are provided inside the first ring body 1102, one of the sliding rods 1105 is fixedly connected to a grinder 1108 at the other end, and the other sliding rod 1105 is fixedly connected to a welding gun 1109 at the other end. A limiting groove 1110 is provided on the surface of the fixed plate 9, and two cylindrical seats 1104 are respectively located at both ends of the first ring body 1102, and two sliding sleeves 1106 are fixedly connected to the first ring body 1102 and the second ring body 1103. The other side of the first ring body 1102 is fixedly connected to the The limiting groove 1110 is rotatably connected. When in use, after the exhaust pipe is adjusted, the alternating mechanism 11 is used to first grind it before welding, and then adjust it for welding. After welding, it is polished again to ensure its aesthetics. Specifically, as the movable seat 1004 moves, the connecting body 1101 is driven, and then the first ring body 1102 and the second ring body 1103 rotate. Since the two sliding sleeves 1106 are fixed between the first ring body 1102 and the second ring body 1103, the two sliding sleeves 1106 move on the corresponding sliding rod 1105 respectively. When rotating in the opposite direction, one of the sliding sleeves 1106 moves upward on the corresponding sliding rod 1105, and then the grinder 1108 moves to the middle end to grind the exhaust pipe, and the other sliding sleeve 1106 moves downward on the corresponding sliding rod 1105. The welding gun 1109 will move outward, and then move in one of the movable grooves 1107, and then during welding, it moves forward, thereby realizing the entire grinding and welding work.

[0025] The working principle of this embodiment is as follows. When the motorcycle exhaust pipe is placed in the main body 1, the first motor 501 on the top of one side of the main body 1 is started to drive the first drive shaft 502 to rotate. Since the first synchronous wheel 503 and the second synchronous wheel 505 are connected by the first synchronous belt 504, the two bidirectional threaded rods 507 are rotated, and then the multiple first fixing seats 506 on the two bidirectional threaded rods 507 move thereon respectively. When the head end of the exhaust pipe reaches the direction-changing clamping mechanism 7, the hydraulic cylinder 702 inside the clamp seat 701 is started to move The first connecting plate 703 is pushed upward. Since the first connecting plate 703 and the clamping body 706 are connected to two connecting rods 707 on both sides, when the first connecting plate 703 moves upward, the two connecting rods 707 support the clamping bodies 706 on both sides of the second connecting plate 705 upward until the head end of the exhaust pipe is clamped. Then, after the top of the reversing clamp mechanism 7 is stressed, the steering column 708 rotates in the direction of the exhaust pipe, which pulls a spring 710 on the outer wall of the steering column 708. After the exhaust pipe is clamped and adjusted, the third motor at the front end of the movable block 1001 is started. 1002 drives the one-way threaded rod 1003 to rotate, so that the movable seat 1004 can move smoothly on the one-way threaded rod 1003. As the movable seat 1004 moves, the connecting body 1101 is driven, and then the first ring body 1102 and the second ring body 1103 rotate, and the movable block 1001 is also adjusted along the rotation direction, so that the two sliding sleeves 1106 move on the corresponding sliding rod 1105 respectively. When rotating in the reverse direction, one of the sliding sleeves 1106 moves upward on the corresponding sliding rod 1105, and then the connecting body 1101 is driven. The grinder 1108 moves toward the middle end to grind the exhaust pipe, and another sliding sleeve 1106 moves downward on the corresponding sliding rod 1105, and the welding gun 1109 moves outward, so that welding and grinding are performed alternately. After the adjustment is completed, the second motor 801 at the bottom of one side of the main body 1 is started to drive the third synchronous wheel 803 on the outer wall of the second drive shaft 802 to rotate, and the limiting wheels 807 on the outer wall of multiple rotating shafts 806 are used to fix the synchronous ring 805 for rotation, so that the grinder 1108 and the welding gun 1109 can run around the exhaust pipe.
