Description

Technical Field

[0001] This utility model relates to the field of refrigeration welding technology, and more specifically, to a refrigeration evaporator welding device. Background Technology

[0002] In the refrigeration equipment manufacturing industry, the evaporator, as a key heat exchange component in a refrigeration system, directly determines the overall energy efficiency and operational stability of the refrigeration equipment. Among these factors, the welding quality between the evaporator tubes and the heat transfer plate is one of the core factors affecting the heat exchange efficiency and service life of the evaporator.

[0003] Currently, the welding equipment for refrigeration evaporators on the market mainly uses manual hand-held welding torches to connect the evaporator tubes and heat transfer plates. This includes components such as the welding torch, clamps, and simple positioning brackets. Although this traditional welding method allows operators to adjust the angle of the welding torch and the amount of heat input to suit different welding positions based on their experience, it has revealed significant shortcomings in actual production.

[0004] Since the welding trajectory relies entirely on manual visual positioning and manual control, it is difficult to guarantee the uniformity of the weld. Operational deviations can easily lead to incomplete welding or overheating at the contact surface between the evaporator tube and the heat transfer plate, directly affecting the heat exchange performance and sealing reliability of the evaporator. At the same time, in welding scenarios with complex curved surfaces or narrow spaces, manual operation makes it difficult to achieve precise alignment between the welding torch and the weld, resulting in low welding efficiency and large fluctuations in product qualification rate.

[0005] In addition, prolonged handheld welding torch operation can increase the labor intensity of operators and increase the risk of exposure to high temperature, arc light and harmful gases. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welding equipment for refrigeration evaporators that can automatically weld.

[0007] To achieve the above objectives, this utility model provides the following technical solution: The refrigeration evaporator welding equipment includes a housing, a material placement block disposed on the top of the housing for placing the evaporator tube and heat transfer plate to be welded, and a clamping part disposed on the material placement block for clamping the evaporator tube and heat transfer plate to be welded. The equipment also includes a position adjustment mechanism and a grinding mechanism assembly. The position adjustment mechanism is disposed on the top of the housing and includes a lifting part, a driving part, a rotating part, a displacement part, and a first welding machine. The lifting part is slidably disposed on the top of the housing. The driving part is disposed at the bottom of the lifting part and above the clamping part. The rotating part is disposed at the bottom of the driving part. The displacement part is slidably disposed beside the rotating part. The first welding machine is disposed below the displacement part and is used to weld the evaporator tube and heat transfer plate placed and clamped on the clamping part. The grinding mechanism assembly is disposed at the bottom of the rotating part and beside the displacement part, and is used to grind the weld joint of the evaporator tube and heat transfer plate after welding.

[0008] By adopting the above technical solution, the problem of manual welding has been solved, and welding efficiency has been improved.

[0009] The present invention is further configured such that: the position adjustment mechanism includes a linear driver and a first telescopic cylinder; the linear driver is disposed on the side of the rotating part; the first telescopic cylinder has multiple cylinders and is disposed on the bottom of the housing, and the output ends of the multiple first telescopic cylinders are all connected to the bottom of the material block, but when the first telescopic cylinder is started, it can drive the multiple material blocks to move in an upward or downward state.

[0010] The present invention is further configured such that: the position adjustment mechanism also includes a second telescopic cylinder; there are multiple second telescopic cylinders respectively disposed on the top of the housing, and the output ends of the multiple second telescopic cylinders are all connected to the lifting part, so that when the second telescopic cylinder is started, it can drive the lifting part to a sliding state.

[0011] The present invention is further configured such that: the position adjustment mechanism includes a flipping part and a second welding machine; the flipping part is disposed at the bottom of the rotating part and located beside the displacement part; the second welding machine is rotatably disposed beside the flipping part, and when the flipping part flips, it can drive the second welding machine to be in a synchronous flipping state.

[0012] The present invention is further configured such that: the grinding mechanism assembly includes a setting part, a rotating part, and a grinding device; the setting part is installed at the bottom of the displacement part, and the first welding machine is fixedly connected to the setting part; the rotating part is rotatably installed at the bottom of the setting part; the grinding device is set at the bottom of the rotating part, and the grinding device is located beside the first welding machine.

[0013] The present invention is further configured such that: the grinding mechanism assembly also includes a fixed frame and a third telescopic cylinder; the fixed frame is disposed on the side of the rotating part and above the material block; the third telescopic cylinder is disposed below the fixed frame, and the output end of the third telescopic cylinder is fixedly connected to the outside of the grinding device, so that when the third telescopic cylinder is started, it can drive the grinding device to move in a downward or upward movement state.

[0014] The present invention is further configured such that: the grinding mechanism assembly includes a rotary driver, an air pump and an exhaust pipe; the rotary driver is installed on the top of the mounting part and the output end of the rotary driver is connected to the rotating part; the air pump is located at the bottom of the rotating part and is located between the grinding device and the first welding machine; the exhaust pipe is located at the bottom of the air pump and the exhaust end of the exhaust pipe faces downward of the grinding device.

[0015] By adopting the above technical solution, after the grinding device finishes grinding, the air pump starts and blows away the iron filings generated after grinding through the exhaust pipe, which can reduce the adhesion of iron filings to the evaporator tube and heat transfer plate after welding.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] By setting up a position adjustment mechanism, the lifting unit can drive the driving unit, rotating unit, displacement unit, and first welding machine to move synchronously when it rises or falls, thereby adjusting the position of the first welding machine so that it can move towards the evaporator tube and heat transfer plate to be welded. This allows for vertical position adjustment of the first welding machine. When it is necessary to adjust the rotation of the first welding machine along the axis of the driving unit, the driving unit rotates first, which in turn drives the lifting unit, displacement unit, and first welding machine to rotate, thus adjusting the rotational position of the first welding machine along the rotating unit. Then, the first welding machine can slide horizontally on the top of the rotating unit via the displacement unit. This allows the position of the first welding machine to be adjusted vertically, horizontally, and rotationally, adapting to the welding work of evaporator tubes and heat transfer plates, solving the problem of manual welding, and improving welding efficiency.

[0018] By incorporating a grinding mechanism, the rotary drive can rotate the rotating part upon startup, thereby enabling the switching of positions between the first welding machine and the grinding device. After the grinding device finishes grinding, the air pump starts and blows away the iron filings generated during grinding through the exhaust pipe, reducing the adhesion of iron filings to the evaporator tubes and heat transfer plates after welding.

Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] Embodiment 1 includes a housing 1, a material placement block 2 disposed on the top of the housing 1 for placing the evaporator tube and heat transfer plate to be welded, and a clamping part 3 disposed on the material placement block 2 for clamping the evaporator tube and heat transfer plate to be welded. The refrigeration evaporator welding equipment also includes a position adjustment mechanism 4 and a grinding mechanism assembly 5. The position adjustment mechanism 4 is disposed on the top of the housing 1 and includes a lifting part 41, a driving part 42, a rotating part 43, a displacement part 44, and a first welding machine 45. The lifting part 41 is slidably disposed on the top of the housing 1; the driving part 42... The lifting part 41 is located at the bottom and above the clamping part 3; the rotating part 43 is located at the bottom of the driving part 42; the displacement part 44 is slidably located beside the rotating part 43; the first welding machine 45 is located below the displacement part 44, and the first welding machine 45 is used to perform welding work on the evaporator tube and heat transfer plate to be welded that are placed and clamped on the clamping part 3; the grinding mechanism assembly 5 is located at the bottom of the rotating part 43 and beside the displacement part 44, and the grinding mechanism assembly 5 is used to grind the weld joint of the evaporator tube and heat transfer plate after welding.

[0031] Specifically, the clamping part 3 is preferably a servo cylinder. When the servo cylinder is started, it can drive the clamping part 3 to move and clamp the evaporator tube and heat transfer plate to be welded. First, the evaporator tube and heat transfer plate to be welded are placed above multiple material blocks 2 by means of a robotic arm. The driving part 42 is preferably a servo motor. When the driving part 42 is started, it can drive the rotating part 43 to rotate. This allows the driving part 42, the rotating part 43, the displacement part 44 and the first welding machine 45 to move synchronously when the lifting part 41 rises or falls, thereby realizing the adjustment of the position of the first welding machine 45, so that the first welding machine 45 can move towards the evaporator tube and heat transfer plate to be welded. At this point, the vertical position of the first welding machine 45 can be adjusted. When it is necessary to adjust the rotation of the first welding machine 45 along the axis of the drive unit 42, the drive unit 42 rotates first, which in turn drives the rotating unit 43, the displacement unit 44, and the first welding machine 45 to rotate. This allows the rotational position of the first welding machine 45 along the rotating unit 43 to be adjusted. Then, the first welding machine 45 can slide horizontally on the top of the rotating unit 43 via the displacement unit 44. This allows the position of the first welding machine 45 to be adjusted vertically, horizontally, and rotationally, which can adapt to the welding work of evaporator tubes and heat transfer plates, and solves the problem of manual welding, thus improving welding efficiency. After welding is completed, a robotic arm is used to remove the welded evaporator tubes and heat transfer plates for unloading.

[0032] See Figure 3The position adjustment mechanism 4 also includes a linear driver 46 and a first telescopic cylinder 47; the linear driver 46 is located on the side of the rotating part 43; there are multiple first telescopic cylinders 47 respectively located at the bottom of the housing 1, and the output ends of the multiple first telescopic cylinders 47 are all connected to the bottom of the material block 2, but when the first telescopic cylinder 47 is started, it can drive the multiple material blocks 2 to move in an upward or downward state.

[0033] Specifically, the output end of the linear actuator 46 is equipped with a ball screw threadedly connected to the displacement part 44. When the ball screw is activated, it drives the displacement part 44 to move horizontally, thereby enabling the displacement part 44 to move the first welding machine 45. To accommodate the welding of longer evaporation tubes by the first welding machine 45, the first telescopic cylinder 47 is activated, which in turn drives the material block 2 to slide upward. This lifts the heat transfer plate and the evaporation tube, allowing the longer evaporation tube to pass through the top of the casing 1, thus improving the welding adaptability of the evaporation tube and heat transfer plate to be welded.

[0034] See Figure 4 The position adjustment mechanism 4 also includes a second telescopic cylinder 48; there are multiple second telescopic cylinders 48 respectively disposed on the top of the housing 1, and the output ends of the multiple second telescopic cylinders 48 are all connected to the lifting part 41. When the second telescopic cylinder 48 is started, it can drive the lifting part 41 to a sliding state.

[0035] Specifically, when the evaporator pipe is long and the position of the rotating part 43 needs to be adjusted, the second telescopic cylinder 48 is first started and drives the lifting part 41 to rise into a sliding state. During this process, the lifting part 41 can drive the rotating part 43, the displacement part 44 and the first welding machine 45 to rise synchronously, so that the position of the first welding machine 45 can be adjusted according to the actual welding needs of the evaporator pipe and the heat transfer plate.

[0036] See Figure 4 and Figure 5 The position adjustment mechanism 4 also includes a flipping part 49 and a second welding machine 491; the flipping part 49 is disposed at the bottom of the rotating part 43 and located beside the displacement part 44; the second welding machine 491 is rotatably disposed beside the flipping part 49, and when the flipping part 49 flips, it can drive the second welding machine 491 to a synchronous flipping state.

[0037] Specifically, a motor for controlling the rotation of the second welding machine 491 is provided on the side of the flipping part 49. When the motor is started, it can drive the second welding machine 491 into a flipping state. When the first welding machine 45 is welding the evaporator and heat transfer plate to be welded, the second welding machine 491 is in a flipped state away from the rotating part 43. Then the motor starts and drives the second welding machine 491 to flip until the second welding machine 491 is above the evaporator tube and heat transfer plate to be welded. Then the second welding machine 491 can perform welding on the middle position of the evaporator tube and heat transfer plate to be welded, avoiding the welding blind spot of the first welding machine 45. After welding, the second welding machine 491 flips again without affecting the subsequent welding of the first welding machine 45.

[0038] See Figure 4 and Figure 5 The grinding mechanism assembly 5 includes a setting part 51, a rotating part 52, and a grinding device 53; the setting part 51 is installed at the bottom of the displacement part 44, and the first welding machine 45 is fixedly connected to the setting part 51; the rotating part 52 is rotatably installed at the bottom of the setting part 51; the grinding device 53 is located at the bottom of the rotating part 52, and the grinding device 53 is located beside the first welding machine 45.

[0039] Specifically, the rotating part 52 is rotatable. When the first welding machine 45 is welding the evaporator tube and the heat transfer plate to be welded, the rotating part 52 does not rotate in this state. After the welding is completed, the rotating part 52 rotates and changes the position of the grinding device 53 and the first welding machine 45. Then the grinding device 53 can grind the welded position after welding to avoid burrs after welding.

[0040] See Figure 5 The grinding mechanism assembly 5 also includes a fixed frame 54 and a third telescopic cylinder 55; the fixed frame 54 is located beside the rotating part 52 and above the material block 2; the third telescopic cylinder 55 is located below the fixed frame 54, and the output end of the third telescopic cylinder 55 is fixedly connected to the outside of the grinding device 53. When the third telescopic cylinder 55 is started, it can drive the grinding device 53 to move in a downward or upward movement state.

[0041] Specifically, when the positions of the grinding device 53 and the first welding machine 45 change, the third telescopic cylinder 55 starts and drives the grinding device 53 to move towards the position of the welded evaporator tube and heat transfer plate until the grinding device 53 contacts the welded position. At this time, the welded position can be ground. In the initial state, the grinding device 53 is not on the same horizontal plane as the bottom of the first welding machine 45. The horizontal plane of the first welding machine 45 is higher than the horizontal plane of the grinding device 53, so that the first welding machine 45 will not make the grinding device 53 contact the evaporator tube and heat transfer plate to be welded during welding.

[0042] See Figures 5-7 The grinding mechanism assembly 5 also includes a rotary driver 56, an air pump 57, and an exhaust pipe 58; the rotary driver 56 is mounted on the top of the mounting part 51, and the output end of the rotary driver 56 is connected to the rotating part 52; the air pump 57 is located at the bottom of the rotating part 52, and the air pump 57 is located between the grinding device 53 and the first welding machine 45; the exhaust pipe 58 is located at the bottom of the air pump 57, and the exhaust end of the exhaust pipe 58 faces downwards from the grinding device 53.

[0043] Specifically, when the rotary driver 56 is started, it can drive the rotating part 52 to rotate, thereby switching the positions of the first welding machine 45 and the grinding device 53. After the grinding device 53 finishes grinding, the air pump 57 starts and blows away the iron filings generated after grinding through the exhaust pipe 58, which can reduce the adhesion of iron filings to the evaporator tube and heat transfer plate after welding.

[0044] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
