Description

Technical Field

[0001] This utility model relates to the field of cooling cabinet technology, and in particular to a copper tube welding device for cooling cabinets. Background Technology

[0002] A cooling cabinet is a refrigeration device specifically designed for transporting frozen or temperature-controlled fresh goods. It maintains a set temperature environment through a refrigeration system to ensure the stable quality of temperature-sensitive goods such as frozen fish, aquatic products, fruits and vegetables, and dairy products. Its refrigeration methods include mechanical, external, and plate-type technologies. The temperature control range can reach -60℃ to +30℃, and it also has humidity control and ventilation functions. Cooling cabinets use copper pipes for refrigeration, and welding equipment is required to weld the copper pipes.

[0003] As shown in the reference case "An auxiliary welding device for copper pipes" (publication number CN220547847U), by rotating the worm gear, the worm gear drives the worm wheel and the rotating shaft, which in turn drives the rotating plate to rotate. This allows for adjustment of the angle during auxiliary welding of the copper pipe. The moving block on the rotating plate cooperates with this adjustment to precisely adjust the angle and distance during welding. This allows the copper pipe to be welded into a bend at a certain angle while maintaining clamping, making it highly practical.

[0004] According to the above reference materials, in the above device, the positioning frame and the fixing plate are arranged opposite each other to position and clamp the two copper pipes. The rotating block on the worm drives the worm wheel to rotate. The worm wheel and the rotating shaft rotate synchronously. The rotating shaft drives the rotating plate to rotate to adjust the angle of the copper pipe on its inner side. However, when the device is used to weld the copper pipe, there is a tendency for the welding machine and the copper pipe to deviate. The induction coil of the welding machine is prone to contact with the copper pipe, which affects the welding of the copper pipe and makes it inconvenient to accurately weld the copper pipe, thus reducing the effectiveness of the device. Utility Model Content

[0005] Therefore, it is necessary to provide a copper pipe welding device for cooling cabinets to address the problem of inconvenience in accurately welding copper pipes.

[0006] The device includes a base plate, on one end of which a high-frequency welding machine body is mounted. Two induction coils are mounted on the front end of the high-frequency welding machine body. A positioning mechanism is provided at the top of the base plate. The positioning mechanism includes a positioning block fixedly connected to the top of the other end of the base plate. One end of the top of the positioning block is aligned with the induction coil. A fixing plate is slidably connected to one end of the top of the base plate. A mounting plate is slidably connected to the top of the inner wall of the fixing plate. Two sets of clamping blocks are provided on both sides of the top of the mounting plate, with two clamping blocks in each set. A fixing component is provided at the top of the mounting plate.

[0007] In one embodiment, the positioning mechanism further includes a first electric push rod installed on both sides of the inner wall of the mounting plate, one end of the first electric push rod being fixedly connected to the bottom end of the mounting plate.

[0008] In one embodiment, one of the clamping blocks is fixedly connected to the top of the fixing plate, and the other clamping block is disposed above the one of the clamping blocks.

[0009] In one embodiment, a second electric push rod is installed in the middle of the inner wall of the base plate, and one end of the second electric push rod is fixedly connected to the bottom end of the fixed plate.

[0010] In one embodiment, a number of evenly arranged sliders are fixedly connected to the bottom end of the high-frequency welding machine body. The sliders are slidably connected to the top end of the base plate. An electric slide rail is installed on the inner wall of the base plate, and the electric slide rail is fixedly connected to one of the sliders.

[0011] In one embodiment, the fixing component includes a mounting bracket fixedly connected to one side of one of the clamping blocks, a connecting bracket slidably connected to the top of the mounting bracket, and the connecting bracket being fixedly connected to the other clamping block.

[0012] In one embodiment, a fixing bolt is slidably connected to one side of the mounting bracket, one end of the fixing bolt passes through the mounting bracket and is threadedly connected to the connecting bracket, and a washer is sleeved on one end of the fixing bolt.

[0013] In one embodiment, a groove is provided on one side of the mounting bracket, and the fixing bolt is slidably connected to the inner wall of the groove.

[0014] Beneficial effects 1. The above-mentioned copper pipe welding device for the cooling cabinet has two sets of clamps in a V-shape structure, which can quickly place and position the copper pipe for welding. One end of the top of the positioning block is an arc structure, and the central axis of the top end of the positioning block is aligned with the middle of the induction coil. By fitting the copper pipe against the positioning block, the copper pipe can be positioned in the middle of the induction coil, improving the welding effect. The height of the copper pipe can be adjusted by the first electric push rod, and the position of the copper pipe on the clamp can be adjusted by the second electric push rod in cooperation with the fixing plate. The main body of the high-frequency welding machine and the induction coil move to one end through the electric slide rail to weld the copper pipe. The welding point of the copper pipe can be accurately positioned, improving the welding accuracy of the welding device. 2. When welding copper pipes, another clamping block slides within the mounting frame via a connecting bracket. This clamping block, in conjunction with one of the clamping blocks, clamps and secures the copper pipe, preventing displacement during welding. The fixing bolts on the connecting bracket engage with the grooves, allowing the bracket to slide along the mounting frame. The fixing bolts also engage with the washers to fix the position of the connecting bracket. The washers increase the friction coefficient between the fixing bolts and the mounting frame, effectively clamping and positioning the copper pipe and improving the welding device's performance.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5 This invention describes a copper tube welding device for a cooling cabinet.

[0020] In one embodiment, a copper pipe welding device for a cooling cabinet includes a base plate 100. A high-frequency welding machine body 200 is mounted on one end of the top of the base plate 100. Two induction coils 300 are mounted on the front end of the high-frequency welding machine body 200. A positioning mechanism 400 is provided at the top of the base plate 100. The positioning mechanism 400 includes a positioning block 410 fixedly connected to the top of the other end of the base plate 100. One end of the top of the positioning block 410 is aligned with the induction coil 300. A fixing plate 420 is slidably connected to one end of the top of the base plate 100. An mounting plate 430 is slidably connected to the top of the inner wall of the fixing plate 420. Two sets of clamping blocks 440 are provided on both sides of the top of the mounting plate 430, with two clamping blocks 440 in each set. A fixing component 490 is provided at the top of the mounting plate 430.

[0021] It should be noted that copper pipe welding equipment typically consists of three parts: an induction welding system, a control system, and tooling fixtures. Induction welding system Typically equipped with a high-frequency welding machine, the welding area is rapidly heated by an induction coil 300, and temperature closed-loop control is achieved in conjunction with an infrared thermometer.

[0022] control system Most systems utilize PLCs for intelligent control and are equipped with touchscreens to display real-time data such as temperature profiles and welding counts. They also support manual / automatic mode switching and fault code display.

[0023] tooling fixtures Pneumatic clamps are used to achieve precise axial and radial positioning of copper tubes. Some devices also include an automatic positioning pin correction system to reduce clamping deviations.

[0024] The positioning mechanism 400 can clamp and fix the copper tube to be welded by two clamping blocks 440. The position of the copper tube on the clamping block 440 can be adjusted by the cooperation of the first electric push rod 450 and the second electric push rod 460 and it can be attached to one end of the positioning block 410 for welding. The positioning mechanism 400 can be used in conjunction with the fixing component 490 to position and adjust the welding point of the copper tube without affecting the normal use of the welding device.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the positioning mechanism 400 also includes a first electric push rod 450 installed on both sides of the inner wall of the fixed plate 420. One end of the first electric push rod 450 is fixedly connected to the bottom end of the mounting plate 430. One clamping block 440 is fixedly connected to the top end of the fixed plate 420, and another clamping block 440 is disposed above the clamping block 440. A second electric push rod 460 is installed in the middle of the inner wall of the base plate 100. One end of the second electric push rod 460 is fixedly connected to the bottom end of the fixed plate 420. Several evenly arranged sliders 470 are fixedly connected to the bottom end of the high-frequency welding machine body 200. The sliders 470 are slidably connected to the top end of the base plate 100. An electric slide rail 480 is installed on the inner wall of the base plate 100. The electric slide rail 480 is fixedly connected to one of the sliders 470.

[0026] In this embodiment, one of the clamping blocks 440 can place the welding copper tube. The height of the welding copper tube can be adjusted by driving the mounting plate 430 upward through the first electric push rod 450. The position of the welding copper tube can be adjusted by driving the fixing plate 420 to one end through the second electric push rod 460. The welding copper tube can be made to fit with one end of the top of the positioning block 410, so that the welding position of the welding copper tube is aligned with the induction coil 300. The electric slide rail 480 cooperates with one of the sliders 470 to adjust and move the position of the high-frequency welding machine body 200 and the induction coil 300, so as to weld the welding copper tube, quickly and accurately position the welding copper tube, and improve the welding effect of the welding device.

[0027] like Figure 5 As shown, the fixing assembly 490 includes a mounting bracket 491 fixedly connected to one side of one of the clamping blocks 440. A connecting bracket 492 is slidably connected to the top of the mounting bracket 491. The connecting bracket 492 is fixedly connected to the other clamping block 440. A fixing bolt 493 is slidably connected to one side of the mounting bracket 491. One end of the fixing bolt 493 passes through the mounting bracket 491 and is threadedly connected to the connecting bracket 492. A washer 494 is sleeved on one end of the fixing bolt 493. A groove 495 is provided on one side of the mounting bracket 491. The fixing bolt 493 is slidably connected to the inner wall of the groove 495.

[0028] In this embodiment, when fixing the welded copper pipe, the connecting frame 492 moves another clamping block 440 downward along the inner wall of the mounting frame 491. The welding copper pipe can be clamped and fixed by cooperating with one of the clamping blocks 440. When the connecting frame 492 slides, it drives the fixing bolt 493 to slide downward along the groove 495. Rotating the fixing bolt 493 and connecting frame 492 threadedly connects the washer 494 to the mounting frame 491, which can fix the other clamping block 440. This can position and clamp the welding copper pipe, improving the welding effect of the welding copper pipe.

[0029] Working principle: The copper tube to be welded is placed on two clamping blocks 440. The control system drives the first electric push rod 450 to move the copper tube on the mounting plate 430 upward to align with one end of the positioning block 410. The control system then drives the second electric push rod 460 to move the fixing plate 420 to one end, so that the copper tube contacts the positioning block 410, which can position and adjust the welding point of the copper tube. The connecting frame 492 moves the other clamping block 440 downward to fix the copper tube on one of the clamping blocks 440. Manually rotating the fixing bolt 493 and connecting frame 492 causes the washer 494 to contact the mounting frame 491, which can fix the other clamping block 440. The control system drives the electric slide rail 480 to cooperate with one of the sliders 470, which can move the induction coil 300 at one end of the high-frequency welding machine body 200 to one end, so that the copper tube to be welded is located in the middle of the induction coil 300, which can then be welded.

[0030] It should be noted that the high-frequency welding machine body 200, induction coil 300, first electric push rod 450, second electric push rod 460, electric slide rail 480, etc. mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the high-frequency welding machine body 200, induction coil 300, first electric push rod 450, second electric push rod 460, and electric slide rail 480 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
