Technical Field
[0001] This utility model belongs to the field of refrigeration pipe welding technology, and in particular relates to a refrigeration pipe welding assembly that is easy to assemble. Background Technology
[0002] A refrigeration tube is a cooling tool that converts hot and cold energy through compressed air in a vortex tube. It is mainly used in fields such as machining cooling, electronic component testing, and laboratory low-temperature experiments. Its working principle is based on the separation effect of compressed air within the vortex tube; one end generates low-temperature cold air (down to -20℃), while the other end releases high-temperature hot air (up to 87℃). Precise temperature and flow rate can be controlled by adjusting the valve at the hot air end. This device has no moving parts, requires no chemical refrigerant, and relies on airflow for cooling. It features a compact structure, electromagnetic interference resistance, and resistance to high-temperature and high-humidity environments. In practical applications, small sections of the refrigeration tube need to be welded together to form a refrigeration pipeline to fully utilize its cooling effect. However, the following problems still exist when welding the refrigeration pipeline: When performing welding work, it is necessary to weld around the refrigeration pipe. The traditional welding operation is for the worker to hold a welding gun and rotate it around the refrigeration pipe to weld. There are certain requirements for the rotation speed of the welding gun. Otherwise, some areas will be under-welded and have porosity, while some areas will be over-welded and have weld beads. However, the precision of manual operation is limited, and it is impossible to ensure that the rotation speed is consistent throughout the entire process. When performing welding work, it is necessary to use solder to repair the welded parts. When welding manually, the solder rotates with the welding gun and needs to be fed evenly. The operation is too difficult and difficult to control. It is easy to feed the solder too fast or too slow, resulting in weld beads and porosity, which affects the performance of the refrigeration pipe. During welding, it is inevitable that liquefied solder will drip, polluting the working environment and wasting solder.
[0003] To address these issues, we provide a conveniently assembled refrigeration piping welding assembly. Utility Model Content
[0004] The purpose of this utility model is to provide a convenient assembly for welding refrigeration pipes. By setting up a collection plate, rotating rod, driving gear, motor, sleeve, driven gear, clamping assembly, three-jaw chuck and cylinder, it solves the problems of uneven rotation speed, uneven solder feeding and solder dripping polluting the working environment during refrigeration pipe welding.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a conveniently assembled refrigeration pipe welding assembly, including a workbench, a sleeve, a clamping assembly, a welding torch, and a three-jaw chuck. Two support plates are symmetrically fixedly connected to the top of the workbench. A second support plate is fixedly connected to one side of the top of the workbench between the two support plates. A sleeve is rotatably connected to each of the two support plates. A clamping assembly is located near the center of the workbench around the sleeve. The clamping assembly includes two symmetrically arranged arc-shaped clamping plates inside the sleeve. A three-jaw chuck is located on the side of the second support plate near the center of the workbench. A welding torch is positioned above the center of the workbench. The central axis of the three-jaw chuck is higher than the upper end of the sleeve when viewed from the front. The height of the welding torch is higher than the three-jaw chuck when viewed from the front, and the central axis of the welding torch is directly above the center of the workbench. Before welding, use a three-jaw chuck to hold the solder. Then, insert the two cooling tubes into the sleeves and move them so that the contact points are above the center of the worktable. Next, move the clamping plate to hold and fix the cooling tubes. After fixing, start the welding torch. The two sleeves rotate simultaneously, in the same direction, and at the same speed. After the welding torch heats the cooling tubes to the welding temperature, the three-jaw chuck moves to move the solder to the welding area to weld the two sections of cooling tubes. The welding work is completed after one revolution.
[0006] Furthermore, a cross-shaped support frame is fixedly connected to the center of the top of the workbench, and a limit rod is fixedly connected to the top of each of the four ends of the support frame. A collection tray is provided at the top of the support frame between the four limit rods. Incompletely bonded liquid solder drips down the side of the cooling pipe into the collection tray.
[0007] Furthermore, a driven gear is fixedly connected to the periphery of the sleeve located between the two support plates, and a rotating rod is rotatably connected between the two support plates away from the support plate. A driving gear is fixedly connected to the periphery of the rotating rod near the two support plates, and the driving gear meshes with the driven gear close to it. A motor is fixedly connected to the side of one of the support plates away from the driving gear, and the output shaft of the motor is connected to the end of the rotating rod close to it in a transmission connection. When the motor is started, the output shaft of the motor rotates, which drives the rotating rod and the driving gear to rotate, and in turn drives the driven gear and the two sleeves to rotate, so that the two sections of the refrigeration pipe rotate in the same direction and at the same speed.
[0008] Furthermore, a fixing plate is fixedly connected to the periphery of the sleeve near the center of the worktable. A sliding groove is formed inside the fixing plate above the sleeve, and the sliding groove extends downward through the upper part of the sleeve. Limiting grooves are also formed in the fixing plates on both sides of the upper part of the sliding groove. Two symmetrically distributed sliders are slidably connected in the sliding groove. A limiting block is slidably connected in the limiting groove. The limiting block and the adjacent slider are fixedly connected. The slider and the upper end of the adjacent clamping plate are fixedly connected. By sliding the slider along the groove, the clamping plate can be moved within the sleeve to clamp and fix the refrigeration pipe.
[0009] Furthermore, the slide groove is provided with a rotating shaft that is rotatably connected to the fixed plate. The rotating shaft has two opposite threads on its circumference, and each threaded segment on the rotating shaft is threadedly connected to a slider. Both ends of the rotating shaft extend through the fixed plate and are fixedly connected with nuts. Rotating the nut causes the shaft to rotate, which in turn moves the two sliders closer together or further apart within the groove.
[0010] Furthermore, a fixing rod is fixedly connected to the upper part of the side of the support plate two near the center of the workbench, and the end of the fixing rod away from the support plate two is fixedly connected to the welding gun. The fixing rod provides support for the welding torch.
[0011] Furthermore, a cylinder is fixedly connected to the side of the support plate two away from the center of the workbench, and the piston rod of the cylinder extension end is fixedly connected to the end of the three-jaw chuck nearby. When the cylinder is activated, the piston rod at the extension end of the cylinder extends, which drives the three-jaw chuck to move towards the center of the worktable to feed the solder at a uniform speed.
[0012] This utility model has the following beneficial effects: This invention solves the problem of uneven rotation speed during welding by setting up a rotating rod, a driving gear, a motor, a sleeve, a driven gear, and clamping components. One section of the cooling tube is passed through one sleeve, and the other section is passed through the other sleeve. The positions of the two cooling tubes are moved so that their contact points are above the center of the worktable. The two cooling tubes are clamped by two clamping components. The motor is started, and the motor output shaft rotates, driving the rotating rod and the driving gear to rotate, which in turn drives the driven gear and the sleeve to rotate. This allows the two cooling tubes to rotate in the same direction, at the same speed, and at a uniform speed, achieving the purpose of uniform rotation for welding.
[0013] This invention solves the problem of uneven solder feeding by setting up a three-jaw chuck and a cylinder. Before welding, the three-jaw chuck is used to hold the solder. When welding, the cylinder is started and the piston rod at the telescopic end of the cylinder is slowly extended to achieve uniform and slow feeding, thus preventing porosity and weld beads during welding.
[0014] This invention solves the problem of dripping solder polluting the working environment by setting up a collection tray; the unbonded liquid solder drips downwards and eventually falls into the collection tray, which collects the dripping solder and can be reused after processing, thus achieving the goal of saving costs.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation
[0026] Please see Figure 1-7 This utility model is a conveniently assembled refrigeration pipe welding assembly, including a workbench 1, a sleeve 3, a clamping assembly 4, a welding torch 5, and a three-jaw chuck 6; two support plates 101 are symmetrically fixedly connected to the top of the workbench 1, and a support plate 102 is fixedly connected to one side of the top of the workbench 1 between the two support plates 101. The sleeve 3 is rotatably connected through both support plates 101. The clamping assembly 4 is provided around the sleeve 3 near the center of the workbench 1. The clamping assembly 4 includes two arc-shaped clamping plates 405 symmetrically arranged inside the sleeve 3. The three-jaw chuck 6 is provided on the side of the support plate 102 near the center of the workbench 1. The welding torch 5 is provided above the center of the workbench 1. The central axis of the three-jaw chuck 6 is higher than the higher end of the sleeve 3 when viewed from the front. The height of the welding torch 5 is higher than the three-jaw chuck 6 when viewed from the front, and the central axis of the welding torch 5 is located directly above the center of the workbench 1. Workbench 1 provides a working environment for welding. Before welding, the solder is held in place by a three-jaw chuck 6. The position of the three-jaw chuck 6 is moved so that the end of the solder is close to the center of workbench 1. Then, two sections of cooling tubes are inserted into sleeves 3. The two cooling tubes are moved so that their contact points are above the center of workbench 1. Then, the clamping plate 405 is moved to clamp and fix the cooling tubes. After fixing, the welding torch 5 is started. The two sleeves 3 rotate in the same direction and at the same speed. The welding torch 5 heats the periphery of the welding area of the cooling tubes to the welding temperature. The three-jaw chuck 6 moves and moves the solder to the top of the welding area. The welding torch 5 melts the solder, and the solder drips onto the cooling tubes. After the solder solidifies, the two sections of cooling tubes can be connected. The welding work is completed after one revolution.
[0027] Among them, such as Figure 3 As shown, a cross-shaped support frame 103 is fixedly connected at the center of the top of the workbench 1. Limiting rods 1031 are fixedly connected to the top of each of the four ends of the support frame 103. A collection tray 104 is provided at the top of the support frame 103 located between the four limiting rods 1031. The support frame 103 provides support for the collection tray 104, and the limiting rod 1031 limits the collection tray 104 to prevent it from deviating. The collection tray 104 is large in size and can fully catch the dripping solder. The liquid solder that is not fully bonded can drip into the collection tray 104 along the periphery of the cooling pipe.
[0028] Among them, such as Figure 1 , Figure 2 and Figure 4 As shown, a driven gear 301 is fixedly connected to the periphery of the sleeve 3 located between the two support plates 101. A rotating rod 2 is rotatably connected between the two support plates 101 at a position away from the support plate 102. A driving gear 201 is fixedly connected to the periphery of the rotating rod 2 at a position close to the two support plates 101. The driving gear 201 meshes with the driven gear 301 that is close to it. A motor 202 is fixedly connected to the side of one of the support plates 101 away from the driving gear 201. The output shaft of the motor 202 is connected to the end of the rotating rod 2 that is close to it in a transmission connection. When the motor 202 is started, the output shaft of the motor 202 rotates, causing the rotating rod 2 and the two driving gears 201 to rotate in the same direction and at the same speed, which in turn drives the two driven gears 301 and the two sleeves 3 to rotate together, so that the two sections of the refrigeration pipe can rotate in the same direction and at the same speed.
[0029] Among them, such as Figure 4-6 As shown, a fixing plate 401 is fixedly connected to the sleeve 3 near the center of the worktable 1. A sliding groove 402 is opened inside the fixing plate 401 located above the sleeve 3. The sliding groove 402 extends downward through the upper part of the sleeve 3. Limiting grooves 4021 are also opened in the fixing plates 401 located on both sides of the upper part of the sliding groove 402. Two symmetrically distributed sliders 403 are slidably connected in the sliding groove 402. A limiting block 4031 is slidably connected in the limiting groove 4021. The limiting block 4031 and the slider 403 adjacent to it are fixedly connected. The slider 403 and the clamping plate 405 adjacent to it are fixedly connected at the higher end. By sliding the two sliders 403 towards each other along the slide groove 402, the clamping plate 405 can be moved closer to each other within the sleeve 3 to clamp and fix the refrigeration pipe.
[0030] Among them, such as Figure 4-6 As shown, the slide 402 is provided with a rotating shaft 404 that is rotatably connected to the fixed plate 401. The rotating shaft 404 has two opposite threads on its circumference, and each threaded segment on the rotating shaft 404 is threadedly connected to a slider 403. Both ends of the rotating shaft 404 extend through the fixed plate 401 and are fixedly connected with nuts 4041. Rotating the nut 4041 causes the rotating shaft 404 to rotate, which in turn causes the two sliders 403 to move closer or further apart within the groove 402. Due to the two opposite threaded configurations, the displacement distance of the two clamping plates 405 is consistent, ensuring that the cooling pipe is always located in the center position inside the sleeve 3, preventing the cooling pipe from deviating during rotation.
[0031] Among them, such as Figure 1 , Figure 7 As shown, a fixing rod 501 is fixedly connected to the upper part of the support plate 2 102 near the center of the workbench 1. The end of the fixing rod 501 away from the support plate 2 102 is fixedly connected to the welding gun 5. A cylinder 601 is fixedly connected to the side of the support plate 2 102 away from the center of the workbench 1. The piston rod of the telescopic end of the cylinder 601 is fixedly connected to the end of the three-jaw chuck 6 nearby. The fixed rod 501 provides support for the welding torch 5. The welding torch 5 is located directly above the welding area, which can stably carry out the welding work. When the cylinder 601 is started, the piston rod at the telescopic end of the cylinder 601 is stretched, which can drive the three-jaw chuck 6 to move towards the center of the worktable 1 to carry out the uniform feeding of the welding material.
[0032] The working principle of this embodiment is as follows: Before welding, the solder is held by a three-jaw chuck 6. The position of the three-jaw chuck 6 is moved so that the end of the solder is close to the center of the worktable 1. Then, the two cooling tubes are inserted into the sleeve 3. The two cooling tubes are moved so that their contact points are above the center of the worktable 1. Then, the nut 4041 is rotated, which drives the rotating shaft 404 to rotate. This drives the two sliders 403 to move closer or further apart in the slide groove 402. Due to the two opposite threaded configurations, the two clamping plates 405 move closer to each other to clamp and fix the cooling tubes. After fixing, the welding torch 5 is started, and the motor 202 is started. The output shaft of the motor 202 rotates, driving the rotating rod 2 and the two drive gears 201 to rotate together. The two cooling pipe sections rotate in the same direction and at the same speed, which in turn drives the two driven gears 301 and the two sleeves 3 to rotate together, so that the two cooling pipe sections rotate in the same direction and at the same speed. After the welding torch 5 heats the periphery of the welding part of the cooling pipe to the welding temperature, the cylinder 601 is started. The piston rod at the telescopic end of the cylinder 601 is stretched, which drives the three-jaw chuck 6 to move to the center position of the worktable 1 to feed the solder at a uniform speed. The welding torch 5 melts the solder, and the solder drips onto the cooling pipe. After the solder solidifies, the two cooling pipe sections can be connected. The welding work is completed after one revolution. During the welding process, the liquid solder that is not fully bonded drips down the periphery of the cooling pipe into the collection tray 104. The solder collected in the collection tray 104 can be reused after processing.
[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
