Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly to a welding equipment for the production and processing of motorcycle throttle valves. Background Art

[0002] Motorcycle throttle valves are usually installed at the rear of the engine, and most of them are silver. The throttle valve controls the amount of air entering the vehicle. The entry of air into the cylinder is completed by the throttle valve. The function of the throttle valve is to control the air intake and exhaust of the engine. After the air enters the engine, it will be mixed with gasoline to form a mixture gas, providing power in this way. During operation, the throttle valve controls the engine intake like a valve body. The throttle pipe is not easy to be demolded in one piece during processing and needs to be processed by means of segmented welding, which requires the use of welding equipment to assist in the production and processing of motorcycle throttle valves.

[0003] During the welding process of existing welding equipment, high temperature is generated, which will cause a heat affected zone at the weld position of the motorcycle throttle pipe, resulting in local rapid heating and cooling of the material at the weld position of the motorcycle throttle valve, generating thermal expansion and contraction, and thus causing internal stress concentration in the throttle valve assembly. Excessive temperature changes will cause deformation at the weld position, affecting the welding quality of the motorcycle throttle valve. Summary of the Invention

[0017] The present invention provides a welding device for the production and processing of motorcycle throttle valves. It has the following beneficial effects:

[0018] 1. The welding equipment for the production and processing of motorcycle throttle valves locks the motorcycle throttle valve pipes through the cooperation of the movable locking assembly and the locking and reinforcement mechanism, rotates the pipes by means of the driving motor and the turntable, and welds the joints of the pipes by means of the welding mechanism. The thermal stress reduction mechanism is used to slowly cool the welds of the motorcycle throttle valve pipes step by step, eliminate the influence of thermal stress at the welds, and avoid the deformation of the weld positions caused by excessive temperature changes, so as to improve the welding quality of the motorcycle throttle valves.

[0019] 2. The welding equipment for the production and processing of motorcycle throttle valves makes the moving plate and the vertical plate move through the cooperation of the servo motor and the lead screw, fixes the motorcycle throttle valve pipes in cooperation with the rotating seat and the turntable, and uses the contact between the edge of the connecting plate and the inner wall of the pipe to push the sliding column to slide in the outer sleeve, compressing the compression spring to deform. Then, in cooperation with the sliding of the reinforcement component on the inner wall of the connecting plate and the contact with the inner wall of the pipe, the friction force between the pipe and the inner wall of the pipe is increased to lock and reinforce the pipe. The pipe end fitting component is used to contact the end face of the pipe for end face protection, ensuring that when the driving motor and the turntable rotate, the pipe and the rotating seat rotate synchronously, so that the welding torch can comprehensively weld the joints of the pipe, thereby improving the utilization efficiency of the equipment.

[0020] 3. The welding equipment for the production and processing of motorcycle throttle valves makes the folding plate slide on the arc-shaped block through the sliding of the sliding column. Affected by the arc-shaped slope of the arc-shaped block, the folding plate is lifted, and in cooperation with the flexible material characteristics of the rubber strip, the friction force between the rubber strip and the motorcycle throttle valve pipe is further increased. With the setting of the deformation groove, the friction force and the extrusion force act together to cause the rubber strip to deform, so that the deformation groove fits with the inner wall of the pipe, increasing the contact area, thereby ensuring the stability of the motorcycle throttle valve during rotary welding.

[0021] 4. The welding equipment for the production and processing of motorcycle throttle valves enables the circulating air to enter the storage box through the setting of the air guide box, and in cooperation with the supporting component to support the pipe and leave a space between the pipe and the storage box. It ensures that the diffuser and the direct blowing pipe blow air towards the first dispersion arc plate and the air-gathering arc plate respectively. By using the flow blockage of the air in the dispersion groove, the wind speed is reduced and the volume of air blown towards the weld is reduced, avoiding the rapid cooling of the weld position caused by a large amount of direct air blowing and resulting in deformation. With the settings of different positions and shapes of the dispersion groove and the converging groove, a stepped air circulation path is formed to ensure the cooling effect of the weld, thereby improving the processing quality of the motorcycle throttle valves.

[0022] V. The welding equipment for manufacturing the motorcycle throttle forms an air circulation channel through the cooperation of a transfer box and an inclined pipe. With the setting of an arc-shaped guide plate, the air rotates in the inclined pipe and converges on the swing plate, blowing the swing plate to swing. Then, by using the turbulence plates and evacuation grooves on the swing plate, the air circulation path is disrupted, and the air diffuses in the lower regions of the first and second dispersion arc plates, preventing the air from directly blowing on the weld seam and causing rapid shrinkage at the weld seam, resulting in deformation of the weld seam. Thus, the use safety and processing efficiency of the equipment are ensured. Brief Description of the Drawings

Cooperating with the rotating seat 435 and the turntable 42 to fix the motorcycle throttle pipe. Then, by rotating the output shaft of the driving motor 41 to drive the turntable 42 to rotate, driving the pipe and the rotating seat 435 to rotate synchronously, so that the welding torch 23 can comprehensively weld the joint of the pipe;

[0039] The thermal stress reduction mechanism 3 includes an air guide box 31. The bottom surface of the air guide box 31 is fixedly connected to the top of the frame 1. A support assembly 32 is fixedly installed at the output end of the air guide box 31. A transition air-gathering assembly 33 is fixedly installed inside the top of the support assembly 32.

[0040] The transition air-gathering assembly 33 includes a first dispersion arc plate 331 and a second dispersion arc plate 333. The first dispersion arc plate 331 and the second dispersion arc plate 333 are symmetrically arranged about the center line of the supporting assembly 32. A gas-gathering arc plate 332 is fixedly connected between the bottom ends of the first dispersion arc plate 331 and the second dispersion arc plate 333. Dispersion grooves 334 are formed in the bottom surfaces of the first dispersion arc plate 331 and the second dispersion arc plate 333, and a converging groove 335 is formed in the bottom surface of the gas-gathering arc plate 332.

[0042] Second Embodiment. On the basis of the first embodiment, please refer to Figures 4 to 8 As shown, the diffusion component 34 includes a transfer box 341. The outer surface of the transfer box 341 is fixedly connected to the top inner wall of the base 321. The output end of the air guide box 31 extends into the transfer box 341 and is communicated with the transfer box 341. A direct blowing pipe 343 is fixedly connected to the middle of the upper surface of the transfer box 341. The direct blowing pipe 343 is located below the air-gathering arc plate 332. Diffusion members 342 are arranged at both ends of the top of the transfer box 341. The diffusion members 342 are inclined, and the diffusion members 342 arranged at both ends are respectively located below the first dispersion arc plate 331 and the second dispersion arc plate 333. The bottoms of the diffusion members 342 and the direct blowing pipe 343 are both communicated with the inside of the transfer box 341. Through the setting of the air guide box 31, the circulating air enters the transfer box 341, and the pipeline is supported in cooperation with the supporting arc plate 323;

[0043] The diffuser 342 includes inclined tubes 3421 which are inclined and communicate with the interior of the transfer box 341. An arc-shaped guide plate 3422 is fixedly connected to the inner wall of the inclined tube 3421. A swing plate 3423 is rotatably connected to a position on the inner wall of the inclined tube 3421 away from the arc-shaped guide plate 3422. A turbulence plate 3425 is fixedly connected to the inner surface of the swing plate 3423. Evacuation grooves 3426 are formed on the surface of the turbulence plate 3425. An elastic bent rod 3424 is fixedly connected to the top end of the outer surface of the swing plate 3423, and the bottom end of the elastic bent rod 3424 is fixedly connected to the outer surface of the inclined tube 3421. Through the cooperation of the transfer box 341 and the inclined tube 3421, an air circulation channel is formed. Then, by using the arc-shaped guide plate 3422, the air is rotated in the inclined tube 3421 and concentrated on the swing plate 3423, blowing the swing plate 3423 to swing. By using the turbulence plate 3425 and the evacuation grooves 3426 on the swing plate 3423, the air circulation path is disturbed, so that the air is diffused in the area below the first dispersion arc plate 331 and the second dispersion arc plate 333, preventing the air from directly blowing on the weld, and avoiding rapid shrinkage at the weld and causing deformation of the weld.

[0044] During operation, through the arrangement of the air guide box 31, the circulating air enters the transfer box 341, and the pipe is supported by the supporting arc plate 323. Then, through the cooperation of the transfer box 341 and the inclined tube 3421, an air circulation channel is formed. Further, by cooperating with the arc-shaped guide plate 3422, the air is rotated in the inclined tube 3421 and concentrated on the swing plate 3423, blowing the swing plate 3423 to swing. By using the turbulence plate 3425 and the evacuation grooves 3426 on the swing plate 3423, the air circulation path is disturbed, so that the air is diffused in the area below the first dispersion arc plate 331 and the second dispersion arc plate 333, preventing the air from directly blowing on the weld. The air is directly blown onto the air-gathering arc plate 332 through the direct blowing pipe 343, and the gathered air is blown onto the weld. Together with the air guiding effect at the first dispersion arc plate 331 and the second dispersion arc plate 333, the thermal stress influence at the weld position is eliminated.

[0045] The third embodiment is based on the first and second embodiments. Please refer to Figures 9 to 12As shown in the figure, the locking and reinforcement mechanism 5 includes an outer sleeve 51. The outer surface of the outer sleeve 51 is fixedly connected to the inner surface of the rotating seat 435. A pipe end fitting assembly 55 is fixedly connected to the outer surface of the outer sleeve 51. The outer surface of the pipe end fitting assembly 55 is fixedly connected to the outer surface of the rotating seat 435. A sliding column 52 is slidably connected to the inner wall of the outer sleeve 51. A compression spring 56 is fixedly connected to the surface of one end of the sliding column 52 close to the outer sleeve 51. The end of the compression spring 56 away from the sliding column 52 is fixedly connected to the inner wall of the outer sleeve 51, and the outer surface of the compression spring 56 is slidably connected to the inner surface of the outer sleeve 51. A connecting plate 53 is fixedly connected to the end of the sliding column 52 away from the outer sleeve 51. A reinforcement assembly 54 is hinged to the outer surface of the outer sleeve 51. The end of the reinforcement assembly 54 away from the outer sleeve 51 is slidably connected to the inner wall of the connecting plate 53. By using the contact between the edge of the connecting plate 53 and the inner wall of the pipeline, the sliding column 52 is pushed to slide in the outer sleeve 51, compressing the compression spring 56 to deform. Then, in cooperation with the sliding of the reinforcement assembly 54 on the inner wall of the connecting plate 53 and its contact with the inner wall of the pipeline, the friction force with the inner wall of the pipeline is increased to lock and reinforce the pipeline, and the end face protection is carried out by using the contact between the pipe end fitting assembly 55 and the end face of the pipeline.

[0046] The reinforcement assembly 54 includes a folding plate 541. One end of the folding plate 541 is hinged to the outer surface of the outer sleeve 51. The end of the folding plate 541 away from the outer sleeve 51 is slidably connected to the inner wall of the connecting plate 53. An arc-shaped stopper 542 is fixedly connected to the inner wall of the connecting plate 53. The surface of the folding plate 541 is slidably connected to the outer surface of the arc-shaped stopper 542. A rubber strip 543 is fixedly connected to the outer surface of the folding plate 541 close to the connecting plate 53. A deformation groove 544 is formed on the outer surface of the rubber strip 543. A resilient member 545 is fixedly connected to the bent surface of the folding plate 541. The end of the resilient member 545 away from the folding plate 541 is fixedly connected to the outer surface of the sliding column 52. Through the sliding of the sliding column 52, the folding plate 541 slides on the arc-shaped stopper 542. Affected by the arc-shaped slope of the arc-shaped stopper 542, the folding plate 541 is lifted. And in cooperation with the flexible material property of the rubber strip 543, the friction force with the motorcycle throttle pipeline is increased. By using the deformation generated by the compression of the deformation groove 544 and the combined action of the friction force and the extrusion force, it fits with the inner wall of the pipeline to increase the contact area. The pipe end fitting assembly 55 includes a fixed seat 551. One end of the fixed seat 551 is fixedly connected to the outer surface of the outer sleeve 51, and the outer surface of the fixed seat 551 is fixedly connected to the outer surface of the rotating seat 435. A soft gasket 552 is fixedly connected to the inner surface of the fixed seat 551. A fitting plate 553 is fixedly connected to the inner surface of the soft gasket 552. One end of the fitting plate 553 is fixedly connected to the outer surface of the fixed seat 551. The compression deformation of the soft gasket 552 is used for buffering, and the protection is carried out in cooperation with the fitting of the fitting plate 553 and the pipeline port.

[0047] During operation, by utilizing the contact between the edge of the connecting plate 53 and the inner wall of the pipeline, the sliding column 52 is pushed to slide in the outer sleeve 51, deforming the compression spring 56. Then, through the sliding of the sliding column 52, the folding plate 541 slides on the arc-shaped stopper 542. Affected by the arc-shaped slope of the arc-shaped stopper 542, the folding plate 541 is lifted. Combining with the flexible material characteristics of the rubber strip 543, the friction with the motorcycle throttle pipeline is increased. By utilizing the deformation generated when the deformation groove 544 is pressed, together with the friction and extrusion force, it fits with the inner wall of the pipeline, increasing the contact area and the friction with the inner wall of the pipeline, locking and strengthening the pipeline. And by utilizing the compression deformation of the soft gasket 552 and the fitting contact between the fitting plate 553 and the pipeline port, end face protection is carried out.

[0048] Next, the working principle of the welding equipment for the production and processing of the motorcycle throttle will be specifically described.

[0049] During use, the staff places the pipe to be welded of the motorcycle throttle valve on the supporting arc plate 323, and then, by using the contact between the edge of the connecting plate 53 and the inner wall of the pipe, pushes the sliding column 52 to slide in the outer sleeve 51, compressing the compression spring 56 to deform. Then, through the sliding of the sliding column 52, the folding plate 541 slides on the arc-shaped stopper 542. Affected by the arc-shaped slope of the arc-shaped stopper 542, the folding plate 541 is lifted, and with the flexible material characteristics of the rubber strip 543, the friction with the motorcycle throttle valve pipe is increased. By using the deformation generated when the deformation groove 544 is pressed, combined with the friction and extrusion force, it fits with the inner wall of the pipe, increasing the contact area and the friction with the inner wall of the pipe, locking and strengthening the pipe. Then, the output shaft of the servo motor 431 rotates to drive the lead screw 432 to rotate, causing the moving plate 433 and the vertical plate 434 to move, cooperating with the rotating seat 435 and the locking and strengthening mechanism 5 to move, and cooperating with the turntable 42 to fix the motorcycle throttle valve pipe. At the same time, the output shaft of the cylinder 21 extends and retracts to drive the lifting plate 22 and the welding torch 23 to descend, adjusting the position of the welding torch 23. The output shaft of the driving motor 41 rotates to drive the turntable 42 to rotate, driving the pipe and the rotating seat 435 to rotate synchronously, so that the welding torch 23 comprehensively welds the joint of the pipe. Then, the air guide box 31 is used to guide the air to blow into the base 321, so that the circulating air enters the storage box 341, and cooperates with the supporting arc plate 323 to support the pipe. The storage box 341 and the inclined pipe 3421 cooperate to form an air circulation channel. Then, with the arc-shaped guide plate 3422, the air rotates in the inclined pipe 3421 and concentrates on the swing plate 3423, blowing the swing plate 3423 to swing. By using the turbulent flow plate 3425 and the evacuation groove 3426 on the swing plate 3423, the air circulation path is disturbed, so that the air diffuses in the lower area of the first dispersion arc plate 331 and the second dispersion arc plate 333, avoiding the air blowing directly at the weld. The direct blowing pipe 343 blows the air directly at the air-gathering arc plate 332, gathering the air to blow at the weld, blowing the air at the first dispersion arc plate 331 and the air-gathering arc plate 332. By using the flow blockage of the air in the dispersion groove 334, the wind speed is reduced and the amount of air blowing at the weld is reduced. With the settings of different positions and shapes of the dispersion groove 334 and the converging groove 335, a stepped air circulation path is formed to cool the weld area in a zoning manner, eliminating the influence of thermal stress. After the welding of the motorcycle throttle valve pipe is completed, the locking of the pipe is released, and it can be removed.
