Description

Technical Field

[0001] This utility model relates to the field of pipe welding, and in particular to a positioning device for welding air conditioning water pipes. Background Technology

[0002] During the installation of air conditioning water pipes, argon arc welding is usually used to weld and fix the water pipes to ensure their safety and sealing, thereby ensuring the stability and safety of the air conditioning system.

[0003] The air conditioning water pipe wiring design in related technologies has a curved section, which is to connect two straight pipes through a bend. When workers weld this type of air conditioning pipe, they usually spot weld the two ends of the bend to the corresponding straight pipes one after another, and then fully weld the bend and the two straight pipes in sequence.

[0004] However, visually locating bends and straight pipes by workers is prone to significant errors. If the bend's positioning deviates, workers must break the spot weld and re-weld it. This not only affects work efficiency but also negatively impacts the aesthetics and quality of the air conditioning water pipes due to repeated welding, and therefore needs improvement. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an air conditioning water pipe welding positioning device, which can realize the rapid positioning of air conditioning water pipes, improve work efficiency, and ensure the welding quality and aesthetics of air conditioning water pipes.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an air conditioning water pipe welding positioning device, including a horizontally arranged support frame, support legs respectively provided at the four corners of the bottom of the support frame, a positioning plate horizontally fixedly connected to the support frame, and multiple support holes through the positioning plate, and the multiple support holes are arranged in a matrix.

[0007] A positioning rod is vertically slidably inserted into each of the support holes, and an elastic damping ring is fixedly connected to each of the support holes. The damping ring is sleeved on the corresponding positioning rod so that the positioning rod and the corresponding damping ring form a damping sliding fit.

[0008] Optionally: A limiting plate is horizontally provided below the positioning plate, and the limiting plate is fixedly connected to the support frame. A plurality of limiting holes are provided through the limiting plate, and the plurality of limiting holes are aligned with the plurality of support holes one by one.

[0009] Multiple positioning rods pass through corresponding limiting holes, and each positioning rod is fixedly fitted with a limiting ring. The limiting ring is located between the positioning plate and the limiting plate, and the limiting ring can form an abutment limit with the positioning plate and the limiting plate.

[0010] Optionally: A reset plate is horizontally arranged below the limiting plate, and guide rails are vertically fixedly connected to both sides of the bottom of the limiting plate. Guide blocks are fixedly connected to both sides of the reset plate, and the two guide blocks are vertically slidingly engaged with the corresponding guide rails. The reset plate is used to push the multiple positioning rods to move upward synchronously.

[0011] Optionally, a pair of electric push rods are provided between the limiting plate and the reset plate, with the tail ends of the pair of electric push rods fixedly connected to the limiting plate and the piston ends fixedly connected to the reset plate.

[0012] Optionally, each of the support legs includes a support rod vertically disposed at the bottom of the support frame. The support rod is connected to the support frame via an electric cylinder, and the electric cylinder is used to control the vertical movement of the corresponding support rod.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 An air conditioning water pipe welding positioning device includes a horizontally arranged support frame 1, support legs 2 are respectively arranged at the four corners of the bottom of the support frame 1, a positioning plate 3 is horizontally fixedly connected to the support frame 1, and multiple support holes 4 are arranged through the positioning plate 3. The multiple support holes 4 are arranged in a matrix, and a positioning rod 5 is vertically slidably inserted into each support hole 4.

[0021] Reference Figure 1 Each support hole 4 has an elastic damping ring 6 fixedly connected inside. The damping ring 6 is tightly fitted onto the corresponding positioning rod 5, so that the positioning rod 5 and the corresponding damping ring 6 form a damped sliding fit. In this embodiment, the frictional force between the damping ring 6 and the positioning rod 5 is greater than the weight of the positioning rod 5, preventing the positioning rod 5 from sliding downwards when there is no contact.

[0022] During the downward pressing of the air conditioning water pipe, the positioning rod 5 located directly below the water pipe moves downward. At this time, the positioning rod 5 located beside the water pipe can limit the water pipe horizontally. Simultaneously, in conjunction with the positioning plate 3 supporting and limiting the water pipe, rapid positioning during the welding process can be achieved. This positioning device enables rapid positioning of the air conditioning water pipe with high accuracy. It not only facilitates welding operations for workers but also reduces their workload, improves work efficiency, and ensures welding quality and aesthetics.

[0023] Reference Figure 1 A limiting plate 7 is horizontally positioned below the positioning plate 3 and is fixedly connected to the support frame 1. Multiple limiting holes 8 are provided through the limiting plate 7, and these holes 8 are aligned with multiple support holes 4. Multiple positioning rods 5 pass through their respective limiting holes 8, and each positioning rod 5 is fixedly fitted with a limiting ring 9. The limiting ring 9 is located between the positioning plate 3 and the limiting plate 7, and it can abut against and limit the positioning plate 3 and the limiting plate 7.

[0024] When the positioning rod 5 moves downward and its top retracts into the corresponding support hole 4, the limiting ring 9 abuts against the positioning plate 3 to limit the downward sliding stroke of the positioning rod 5. Similarly, when the positioning rod 5 moves upward and the limiting ring 9 abuts against the support plate, the upward sliding stroke of the positioning rod 5 is limited to prevent excessive sliding and thus ensure the stability of the positioning device.

[0025] Reference Figure 1 A reset plate 10 is horizontally positioned below the limiting plate 7. Guide rails 11 are vertically fixed to both sides of the bottom of the limiting plate 7. Guide blocks 12 are fixedly connected to both sides of the reset plate 10, and the two guide blocks 12 slide vertically with the corresponding guide rails 11. A pair of electric push rods 13 are provided between the limiting plate and the reset plate 10. The tail ends of the pair of electric push rods 13 are fixedly connected to the limiting plate 7, and the piston ends are fixedly connected to the reset plate 10. The pair of electric push rods 13 can jointly control the vertical movement of the reset plate 10. When the reset plate 10 moves upward, it can simultaneously push multiple positioning rods 5 to the reset position.

[0026] Reference Figure 1 Each support leg 2 includes a support rod 21 vertically disposed at the bottom of the support frame 1. The support rod 21 is connected to the support frame 1 via an electric cylinder 22, and the electric cylinder 22 is used to control the vertical movement of the corresponding support rod 21 so that the height of the support plate can be adjusted.

[0027] Reference Figure 1 Each support rod 21 has an adjustment hole 23 at its bottom and an adjustment seat 24 at its bottom. An adjustment screw 25 is vertically fixed to each adjustment seat 24, and the adjustment screw 25 is threadedly connected to the corresponding adjustment hole 23, allowing the support plate and other components to be leveled. Additionally, an adjustment handwheel 26 is fixedly connected to the bottom of each adjustment screw 25, allowing for quick rotation by the operator.

[0028] The positioning device in this embodiment is used as follows:

[0029] Place the positioning device below the straight pipe, and rotate the adjusting handwheel 26 to control the adjusting screw 25 until the support plate is leveled. Then, control the piston ends of the four electric cylinders 22 to extend synchronously. At this time, the support plate moves upward until the straight pipe abuts against the support plate. During this process, the straight pipe presses down the portion of the positioning rod 5 located below it. Next, align the bent pipe with the straight pipe and press it down. The portion of the positioning rod 5 located directly below the bent pipe is pressed down. At this time, the portion of the positioning rod 5 beside the bent pipe and the straight pipe positions the bent pipe and the straight pipe, and then spot welding can be performed on the bent pipe and the straight pipe. Immediately afterwards, control the piston ends of the four electric cylinders 22 to retract synchronously until the positioning device separates from the bent pipe and the straight pipe, and then the bent pipe and the straight pipe can be fully welded and fixed.
