Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, specifically to a welding processing device for refrigeration equipment tanks. Background Technology

[0002] Refrigeration tanks (or simply refrigeration tanks) are devices used for cooling and storing fresh milk or other liquid materials, widely used in the dairy, beverage, and pharmaceutical industries. Their main function is to cool the liquid materials inside the tank to the required low temperature through a refrigeration system, thereby extending their shelf life and preventing bacterial growth. As a pressure-bearing component in a refrigeration system, the quality of the circumferential weld of the refrigeration tank directly affects the system's sealing and safety. Because refrigeration tanks are mostly elliptical in cross-section, traditional welding of refrigeration tanks often involves fixing them with a support frame and then welding manually. Welders must use different welding angles (flat, vertical, overhead, etc.) to weld the circumferential welds at different heights, depending on the angle of the refrigeration tank.

[0003] However, when existing refrigeration tanks are welded manually, the welding efficiency is low, it is difficult to guarantee the stability at various welding angles, and the quality of the weld is poor. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding processing device for refrigeration equipment tanks. An electric cylinder drives a U-shaped frame to rise and fall, while an electric cylinder drives the U-shaped frame on the support plate to move horizontally. A motor on the U-shaped frame drives rollers, causing the refrigeration tank to rotate on the rollers. This ensures that the highest point of the weld seam on the refrigeration tank is always directly below the welding torch, allowing for continuous welding of the refrigeration tank. Furthermore, the welding torch always welds the refrigeration tank at a flat welding angle. Compared to manual welding, this device offers higher welding efficiency and better quality for refrigeration tanks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a welding processing device for refrigeration equipment tank, including a frame, and further including a moving mechanism for moving the refrigeration tank and a welding mechanism for welding the weld seam in the refrigeration tank, wherein the moving mechanism and the welding mechanism are respectively arranged on the frame;

[0006] A plurality of the aforementioned moving mechanisms are arranged in a linear array on the frame. Each moving mechanism includes a fixed frame connected to the frame, a support plate horizontally slidably disposed within the fixed frame, an electric cylinder one vertically disposed on the support plate, and a U-shaped frame connected to the output end of the electric cylinder one. The two ends of the U-shaped frame are provided with rollers for supporting the refrigeration tank, and one end of the U-shaped frame is provided with a motor for driving one of the rollers. The support plate is provided with an electric cylinder two for driving the support plate to slide.

[0007] The inner side of the fixed frame is provided with guide grooves facing each other, and the bearing plate is slidably disposed in the guide grooves.

[0008] The U-shaped frame is equipped with stabilizing rods at both bottom ends, and the stabilizing rods slide through the bearing plate.

[0009] The welding mechanism includes a vertical support with one end mounted on the frame and a horizontal support connected to the vertical support. A welding torch for welding refrigeration tanks is mounted on the horizontal support.

[0010] The bottom side of the cross brace is provided with a plurality of distance measuring sensors facing the refrigeration tank, and the plurality of distance measuring sensors are symmetrically arranged around the welding gun.

[0011] The frame is also equipped with a pushing mechanism to prevent the refrigeration tank from shifting. The pushing mechanism includes two support rods vertically mounted on the frame and an electric cylinder three mounted on the support rods. The drive end of the electric cylinder three is positioned towards the refrigeration tank.

[0012] The support rod is equipped with a second distance sensor facing the refrigeration tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The U-shaped frame is raised and lowered by electric cylinder one, and the U-shaped frame on the bearing plate is moved horizontally by electric cylinder two. The rollers on the U-shaped frame are driven by the motor, which in turn drives the refrigeration tank to rotate on the rollers. This ensures that the highest point of the weld seam of the refrigeration tank is always directly below the welding gun, so that the refrigeration tank can be continuously welded. This ensures that the welding gun is always welding the refrigeration tank at a flat welding angle. Compared with manual welding, the welding efficiency of the refrigeration tank is higher and the quality is better.

[0015] (2) During the welding process, the distance sensor 1 detects whether the cooling tanks on both sides are misaligned and whether the distance to the welding gun is consistent. The distance sensor 2 detects whether the cooling tanks are misaligned in real time and adjusts them in time through the moving mechanism and the pushing mechanism. The welding operation is more precise and the welding quality is better.

[0016] (3) By adjusting the jacking mechanism and the moving mechanism, the position and angle of the two parts of the refrigeration tank can be adjusted respectively, thereby realizing the spot welding and fixing operation on the tank welding processing device, avoiding the weld point breakage caused by uneven stress when hoisting to the welding processing equipment after spot welding, making the welding operation safer and more reliable.

[0025] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] See Figures 1-7 A welding processing device for a refrigeration equipment tank includes a frame 1, a moving mechanism 2 for moving a refrigeration tank 5, and a welding mechanism 3 for welding the weld seam in the refrigeration tank 5. The moving mechanism 2 and the welding mechanism 3 are respectively mounted on the frame 1.

[0027] A number of moving mechanisms 2 are arranged in a linear array on the frame 1. The moving mechanism 2 includes a fixed frame 21 connected to the frame 1, a support plate 22 horizontally slidably arranged in the fixed frame 21, an electric cylinder 23 vertically arranged on the support plate 22, and a U-shaped frame 24 connected to the output end of the electric cylinder 23. Rollers 25 for supporting the refrigeration tank 5 are provided at both ends of the U-shaped frame 24, and a motor 26 for driving one of the rollers 25 is provided at one end of the U-shaped frame 24. An electric cylinder 27 for driving the support plate 22 to slide is provided on the support plate 22.

[0028] The inner side of the fixed frame 21 is provided with a guide groove 211 facing each other, and the bearing plate 22 is slidably disposed in the guide groove 211.

[0029] The two bottom ends of the U-shaped frame 24 are provided with stabilizing bars 221, which slide through the bearing plate 22.

[0030] The welding mechanism 3 includes a vertical support 31 with one end set on the frame 1 and a horizontal support 32 connected to the vertical support 31. A welding torch 33 for welding the refrigeration tank 5 is set on the horizontal support 32.

[0031] Several distance sensors 321 facing the refrigeration tank 5 are provided on the bottom side of the cross brace 32, and the several distance sensors 321 are symmetrically arranged on the periphery of the welding torch 33.

[0032] The frame 1 is also equipped with a pushing mechanism 4 to prevent the refrigeration tank 5 from shifting. The pushing mechanism 4 includes two vertically mounted support rods 41 on the frame 1 and an electric cylinder 42 mounted on the support rods 41. The driving end of the electric cylinder 42 faces the refrigeration tank 5 and is equipped with a pad. The pad increases the contact area with the refrigeration tank 5 to ensure the stability of pushing the refrigeration tank 5.

[0033] A distance sensor 43 facing the refrigeration tank 5 is installed on the support rod 41.

[0034] A controller is installed on the frame 1. The input end of the controller is connected to the distance measuring sensor 321 and the distance measuring sensor 43. The output end of the controller is electrically connected to the electric cylinder 23, the electric cylinder 27, the electric cylinder 42, the motor 26, and the welding torch 33. The position of the refrigeration tank 5 on the welding processing device is detected in real time by the distance measuring sensor 321 and the distance measuring sensor 43, and the refrigeration tank 5 is adjusted by the moving mechanism 2 to ensure welding accuracy and quality.

[0035] The specific working process of this utility model:

[0036] In use, the two parts of the refrigeration tank 5 that need to be welded are placed on the rollers 25 of the two sets of moving mechanisms 2 respectively. First, start the electric cylinder 1 23 and electric cylinder 27. The height of the refrigeration tank 5 on the U-shaped frame 24 is controlled by the electric cylinder 1 23. The bearing plate 22 is driven to slide along the fixed frame 21 by the electric cylinder 27 to control the horizontal position of the refrigeration tank 5. By adjusting the height and position of the refrigeration tank 5, the center of the refrigeration tank 5 is aligned with the electric cylinder 3 42 of the pushing mechanism 4. Then, start the electric cylinder 3 42 of the pushing mechanism 4. The two electric cylinders 3 42 push the two parts of the refrigeration tank 5 close together and leave a weld seam. At this time, the distance sensor 2 43 measures the distance between the outer wall of the refrigeration tank 5 and the support rod 41.

[0037] The height of the refrigeration tank 5 is adjusted by raising and lowering the electric cylinder 23 controlled by the controller. The horizontal movement of the bearing plate 22 is driven by the electric cylinder 27, so that the highest point of the refrigeration tank 5 is directly below the welding torch 33 in the welding mechanism 3. The welding torch 33 is started for spot welding. Then, several motors 26 are started simultaneously, and the motors 26 drive the rollers 25 to rotate synchronously. The rollers 25 drive the refrigeration tank 5 to roll synchronously for a certain distance and then stop. At the same time, in conjunction with the raising and lowering of the electric cylinder 23 and the horizontal extension and retraction of the electric cylinder 27, the other part of the circumferential weld of the refrigeration tank 5 is directly below the welding torch 33. The distance between the refrigeration tank 5 and the welding torch 33 is measured by the distance sensor 321 to ensure that the distance meets the welding requirements. Spot welding is performed again by the welding torch 33. This process is repeated to complete several spot welds at the weld seam, thus completing the temporary fixation of the two parts of the refrigeration tank 5.

[0038] After the spot welding is completed and cooled to form strength, the motor 26 and electric cylinders 23 and 27 continue to work together to ensure that the highest point of the weld is always directly below the welding torch 33. The welding torch 33 continuously welds the weld of the refrigeration tank 5 until the circumferential weld of the refrigeration tank 5 is completed.

[0039] The electric cylinder 23 drives the U-shaped frame 24 to rise and fall, and the electric cylinder 27 drives the U-shaped frame 24 on the support plate 22 to move horizontally. The motor 26 on the U-shaped frame 24 drives the roller 25 to move, thereby causing the refrigeration tank 5 to rotate on the roller 25. This ensures that the highest point of the weld of the refrigeration tank 5 is always directly below the welding gun 33, thus enabling continuous welding of the refrigeration tank 5. This also ensures that the welding gun 33 always welds the refrigeration tank 5 at a flat welding angle. Compared with manual welding, the welding efficiency of the refrigeration tank 5 is higher and the quality is better.

[0040] During the welding process, the distance sensor 321 detects whether the cooling tanks 5 on both sides are misaligned and whether the distance between them and the welding torch 33 is consistent. The distance sensor 43 detects whether the cooling tanks 5 are misaligned in real time and adjusts them in time through the moving mechanism 2 and the pushing mechanism 4. The welding operation is more precise and the welding quality is better.

[0041] By adjusting the jacking mechanism 4 and the moving mechanism 2, the position and angle of the two refrigeration tanks 5 can be adjusted respectively, thereby enabling spot welding and fixing on the tank welding processing device. This avoids the weld point breakage caused by uneven stress when hoisting to the welding processing equipment after spot welding, making the welding operation safer and more reliable.

[0042] In addition, the welding processing device can also perform welding of the longitudinal weld seam of the refrigeration tank 5, see [link / reference]. Figure 7As shown, the refrigeration tank 5, which has been circumferentially welded, is rotated 90 degrees. The electric cylinder 23 of the two side moving mechanisms 2 is activated, and the refrigeration tank 5 is limited by the side of the roller 25. Then, the electric cylinder 27 is activated in conjunction with the movement of the motor 26 to realize the horizontal movement of the refrigeration tank 5. The longitudinal weld is then welded by the welding gun 33. The welding gun 33 is implemented using existing technology and will not be described in detail here.

[0043] Furthermore, existing welding processes for refrigeration tanks lack compensation mechanisms for axial displacement caused by thermal deformation of the tank body, and differences in the linear speeds of multiple sets of rollers result in spiral scratches on the tank surface. Existing equipment generally lacks misalignment warning devices, failing to effectively suppress the accumulation of misalignment in the initial stages of welding. These technical deficiencies severely restrict the yield rate of mass production of high-precision tanks, necessitating the development of an intelligent welding system with multi-dimensional collaborative adjustment and real-time correction functions. This solution addresses these issues through the combination of a moving mechanism 2, a welding mechanism 3, and a pushing mechanism 4.

[0044] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
