Description

Technical Field

[0001] The utility model relates to a welding clamping and positioning device for automobile air-conditioning pipes, belonging to the field of welding and processing equipment for automobile spare parts. Background Technique

[0002] Automobile air-conditioning pipes are important components in the automobile air-conditioning system, used to transport refrigerants and coolants to achieve the functions of cooling and heating the air inside the vehicle. The welding and processing of air-conditioning pipes is a crucial link in the manufacturing process, directly affecting the system's sealing performance, pressure resistance, and service life.

[0003] In the prior art, after the two sections of air-conditioning pipes are centered and clamped, it is necessary to manually move two groups of jigs, moving the two groups of jigs and the fixed two ends of the air-conditioning pipes simultaneously to align the ports of the two sections of air-conditioning pipes. The overall movement is too large and cumbersome, reducing the pipeline docking efficiency and thus the welding and processing efficiency of automobile air-conditioning pipes.

[0004] In summary, the utility model provides a welding clamping and positioning device for automobile air-conditioning pipes to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a welding clamping and positioning device for automobile air-conditioning pipes to solve the problem of reduced welding and processing efficiency caused by the cumbersome pipeline docking method in the above background technique.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions: A welding clamping and positioning device for automobile air-conditioning pipes includes a fixed seat. The four sides of the front side and the four sides of the rear side of the top of the fixed seat are fixedly connected with support rods. A connecting plate is fixedly connected between the tops of every four support rods. The four sides of the bottoms of the two connecting plates are fixedly connected with electric push rods. A first mounting plate is fixedly connected between the output ends of every two longitudinally arranged electric push rods. An upper clamping plate is fixedly connected between the adjacent sides of the tops of every two first mounting plates. On both sides of the top of the fixed seat and directly below each first mounting plate, a support seat is fixedly connected. A second mounting plate is fixedly connected to the top of each support seat. A lower clamping plate is fixedly connected between the adjacent sides of the bottoms of every two second mounting plates. Three rows of electric roller groups are evenly embedded from front to back on the opposite sides of the upper clamping plate and the lower clamping plate.

[0007] Further, the number of rollers in each row of the electric roller group is three, and the lower clamping plate is directly below the upper clamping plate.

[0008] Further, both the upper clamping plate and the lower clamping plate are in the shape of arc-shaped curved plates, and the upper clamping plate and the lower clamping plate are installed in a mirror-symmetrical structure.

[0009] Further, the electric roller set includes three mounting through holes which are opened between the inner arc surface and the outer arc surface of the clamping plate. An electromagnetic shaft is rotatably connected between two sides of the inner wall of the mounting through hole. A roller sleeve is sleeved on the shaft surface of the electromagnetic shaft, and a rubber roller is sleeved outside the roller sleeve.

[0010] Further, the three mounting through holes are circumferentially arranged around the center of the bending radian of the arc-shaped clamping plate and are evenly distributed on the clamping plate from left to right.

[0011] Further, the electromagnetic shaft is fixedly connected to the roller sleeve, and the roller sleeve is fixedly connected to the rubber roller.

[0012] Further, the roller surface of the rubber roller is in an elliptical convex shape, and the top and bottom of the roller surface of the rubber roller extend outside the mounting through hole.

[0013] Advantages of the utility model:

[0014] By respectively placing two sections of automotive air-conditioning pipes to be welded and processed on the tops of two lower clamping plates, then starting each electric push rod to simultaneously push two upper clamping plates, the two sections of air-conditioning pipes can be centered and clamped and fixed at the same time. Then, starting the electric roller sets on the two upper clamping plates and the two lower clamping plates, while driving the two automotive air-conditioning pipes to be centered and clamped, they are conveyed in opposite directions. Without moving the whole fixture, the ports of the two sections of automotive air-conditioning pipes can be quickly aligned, improving the pipe docking efficiency, and thus improving the welding and processing efficiency of the automotive air-conditioning pipes.

[0015] Since the roller surface of the rubber roller is in an elliptical convex shape and the top and bottom of the roller surface of the rubber roller extend outside the mounting through hole, the convex roller surface of the rubber roller can avoid scratching during the pipeline transmission process, thereby effectively improving the clamping and welding processing quality of the automotive air-conditioning pipes.

[0022] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a welding clamping and positioning device for an automotive air-conditioning pipe, including a fixed seat 1. Four support rods 2 are fixedly connected to the periphery of the front side and the periphery of the rear side of the top of the fixed seat 1. A connecting plate 3 is fixedly connected between the tops of every four support rods 2. Electric push rods 4 are fixedly connected to the periphery of the bottoms of the two connecting plates 3. A first mounting plate 5 is fixedly connected between the output ends of every two longitudinally arranged electric push rods 4. An upper clamping plate 8 is fixedly connected between the adjacent sides of the tops of every two first mounting plates 5. Support seats 6 are fixedly connected to both sides of the top of the fixed seat 1 and directly below each first mounting plate 5. A second mounting plate 7 is fixedly connected to the top of each support seat 6. A lower clamping plate 10 is fixedly connected between the adjacent sides of the bottoms of every two second mounting plates 7. Three rows of electric roller groups 9 are evenly embedded from front to back on the opposite sides of the upper clamping plate 8 and the lower clamping plate 10. The number of rollers in each row of the electric roller group 9 is three. The lower clamping plate 10 is directly below the upper clamping plate 8. The upper clamping plate 8 and the lower clamping plate 10 are both arc-shaped curved plates, and the upper clamping plate 8 and the lower clamping plate 10 are installed in a mirror-symmetrical structure. The eight electric push rods 4 are all connected to an external power supply and are provided with the same power control switch, so that the two upper clamping plates 8 can be driven to move simultaneously in the same direction through the four first mounting plates 5

[0024] Please refer to Figures 2-4, the electric roller group 9 includes three mounting through holes 91 which are opened between the inner arc surface and the outer arc surface of the clamping plate. A magnetic shaft 92 is rotatably connected between both sides of the inner wall of the mounting through hole 91. A roller sleeve 93 is sleeved on the shaft surface of the magnetic shaft 92, and a rubber roller 94 is sleeved outside the roller sleeve 93. The magnetic shaft 92 realizes its function based on the working principle of an electromagnetic clutch or a brake. When the electromagnetic coil is energized, the generated electromagnetic force will cause the friction plates in the clutch to engage, thereby transmitting torque. When the electromagnetic coil is de-energized, the friction plates separate and the transmission stops. Similarly, the electromagnetic brake is to make the brake pads and the brake wheel engage through electromagnetic force when energized, thereby realizing the braking function. By rotating the magnetic shaft 92 forward and backward, the roller sleeve 93 and the rubber roller 94 can be driven to rotate forward and backward, so as to convey the automotive air-conditioning pipe clamped between the upper clamping plate 8 and the lower clamping plate 10 back and forth. The three mounting through holes 91 are circumferentially arranged around the center of the bending arc of the circular arc clamping plate and are evenly distributed on the clamping plate from left to right. The output ends of the magnetic shafts 92 inside the electric roller groups 9 mounted on the two upper clamping plates 8 rotate in opposite directions, and the output ends of the magnetic shafts 92 inside the electric roller groups 9 mounted on the two lower clamping plates 10 rotate in opposite directions. The output ends of the magnetic shafts 92 inside the electric roller groups 9 mounted on the upper clamping plate 8 and the lower clamping plate 10 rotate in opposite directions. Place the two sections of automotive air-conditioning pipes to be welded and processed on the tops of the two lower clamping plates 10 respectively, and then start each electric push rod 4 to push the two upper clamping plates 8 at the same time, so that the two sections of air-conditioning pipes can be centered and clamped and fixed at the same time. Then start the electric roller groups 9 on the two upper clamping plates 8 and the two lower clamping plates 10 to drive the two automotive air-conditioning pipes to be conveyed in opposite directions while being centered and clamped, so that the ports of the two sections of automotive air-conditioning pipes can be quickly aligned, improving the pipeline docking efficiency and thus the welding and processing efficiency of the automotive air-conditioning pipe.

[0025] Please refer to Figures 2-4 , the magnetic shaft 92 is fixedly connected to the roller sleeve 93, the roller sleeve 93 is fixedly connected to the rubber roller 94, and the roller surface of the rubber roller 94 is in an elliptical convex shape. The top and bottom of the roller surface of the rubber roller 94 extend outside the mounting through hole 91. By rotating the magnetic shaft 92, the rubber roller 94 can be driven to rotate, so that the two sections of automotive air-conditioning pipes clamped by the two upper clamping plates 8 and the two lower clamping plates 10 can be moved closer to each other and the ports can be automatically aligned. The convex roller surface of the rubber roller 94 can avoid scratching during the pipeline transmission process, thus effectively improving the clamping and welding processing quality of the automotive air-conditioning pipe.

[0026] Detailed implementation method: The output ends of the electromagnetic shafts 92 inside the electric roller groups 9 installed on the two upper clamping plates 8 rotate in opposite directions, the output ends of the electromagnetic shafts 92 inside the electric roller groups 9 installed on the two lower clamping plates 10 rotate in opposite directions, and the output ends of the electromagnetic shafts 92 inside the electric roller groups 9 installed on the upper clamping plate 8 and the lower clamping plate 10 rotate in opposite directions. By placing the two sections of automotive air-conditioning pipes to be welded and processed on the tops of the two lower clamping plates 10 respectively, and then starting each electric push rod 4 to simultaneously push the two upper clamping plates 8, the two sections of air-conditioning pipes can be centered and clamped and fixed at the same time. Then, start the electric roller groups 9 on the two upper clamping plates 8 and the two lower clamping plates 10 to drive the two automotive air-conditioning pipes to be conveyed in opposite directions while being centered and clamped, so that the ports of the two sections of automotive air-conditioning pipes can be quickly aligned, improving the pipeline docking efficiency and thus the welding and processing efficiency of the automotive air-conditioning pipes.

[0027] The roller surface of the rubber roller 94 is in an elliptical convex shape, and the top and bottom of the roller surface of the rubber roller 94 extend to the outside of the mounting through hole 91. The convex roller surface of the rubber roller 94 can avoid scratching during the pipeline transmission process, thus effectively improving the clamping and welding processing quality of the automotive air-conditioning pipes.

[0028] In addition, it should be understood that although this specification is described according to the implementation manners, not every implementation manner only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
