Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled plate detection, in particular to a butt joint device for water-cooled plate water inlet and outlet detection. Background Technique

[0002] With the development of the automotive industry, problems such as environmental pollution and energy shortage brought by automobiles have become increasingly prominent. New energy vehicles have the advantages of environmental protection and the ability to use multiple energy sources, and have gradually become the development trend of the automotive industry. The core structure of new energy vehicles is the power battery, which is very sensitive to temperature. During use, the battery temperature will rise, and too high a temperature will cause battery thermal runaway, affecting battery performance and safety. Therefore, it is crucial to cool the battery pack. As an important part of liquid cooling, the water-cooled plate makes full contact with the battery surface and uses the coolant flowing inside to take away the battery heat to achieve heat exchange, thereby reducing the battery temperature. Therefore, there is an urgent need for a butt joint device for water-cooled plate water inlet and outlet detection in the market.

[0003] However, the existing technology still has the following problems:

[0004] First of all, when the existing water-cooled pipe butt joint device fixes the water-cooled plate, most of them can only fix water-cooled plates of one size. However, if water-cooled plates of other sizes need to be detected, the device can only be replaced, resulting in low applicability of the device.

[0005] Secondly, when the existing water-cooled pipe butt joint device is butt-jointed, it usually requires manual butt-joint by workers. However, due to the position of the water-cooled plate water inlet and outlet being not easy to locate on the production line, it needs to be tried many times to succeed in butt-joint, and the success rate is too low, reducing the detection efficiency. Content of the Utility Model

[0006] In order to solve the problems of low device applicability and low detection efficiency; the purpose of the utility model is to provide a butt joint device for water-cooled plate water inlet and outlet detection.

[0007] To solve the above technical problems, the present utility model adopts the following technical solutions: an insertion device for water-cooled plate water inlet detection, comprising a bottom plate. A helium detection box is fixedly connected to the top end of the bottom plate. An air outlet pipe is fixedly connected to one end of the helium detection box. Helium gas is discharged through the air outlet and introduced into the water-cooled plate to detect the sealing performance of the water-cooled plate. A fixing device is slidably arranged on the top end of the bottom plate. A docking device is fixedly connected to the top end of the bottom plate. The fixing device includes two long plates distributed in a mirror image. Two long rods are slidably arranged on the inner surface of the upper long plate. The two long rods are fixedly connected to the top end of the lower long plate together, and the bottom end of the lower long plate is slidably connected to the top end of the bottom plate. Clamping blocks are fixedly connected to one ends of the two long plates. Two tube grooves distributed in a mirror image are formed at the opposite ends of the two clamping blocks. The two tube grooves in front of the air outlet pipe are used to fix the water inlet pipe of the water-cooled plate. Rubber soft pads are fixedly arranged on the inner surfaces of the four tube grooves. Four telescopic air rods are fixedly connected to the opposite ends of the two long plates. The opposite ends of every four adjacent telescopic air rods are fixedly connected to a clamping plate together. A first motor is fixedly connected to the top end of the bottom plate. The output end of the first motor is fixedly connected to a gear. The outer surface of the gear is meshed with a rack. One end of the rack is fixedly connected to the upper clamping block. Two sliding rods are fixedly connected to the top end of the lower clamping block. The outer surfaces of the two sliding rods are slidably sleeved with the inner surface of the upper clamping block.

[0008] Preferably, the docking device includes a support frame. A push plate is arranged at one end of the support frame. One end of the push plate is fixedly connected to one of the long plates. A push rod is fixedly connected to the end of the push plate away from the two long plates. By driving the movement of the push rod, the fixing device can be driven to move, so that one of the tube grooves can be moved onto the outer surface of the air outlet pipe. Two sliders are fixedly connected to both ends of the push rod. Chute grooves for cooperating with the sliders are formed on the inner walls of both sides of the support frame. A long groove is formed at the top end of the push rod. A rotating rod is slidably connected to the inner surface of the long groove. The top end of the rotating rod is rotatably sleeved with the upper inner wall of the support frame. A second motor is arranged at the top end of the support frame. The output end of the second motor is fixedly connected to the top end of the rotating rod.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1. By setting the fixing device, under the action of the first motor driving the pipe to fix the water inlet of the water-cooled plate, the device can fix water-cooled plates of different sizes, effectively improving the practicability of the device.

[0011] 2. By setting the docking device, under the action of the second motor driving the long plate to move, the air outlet pipe can be accurately docked with the water inlet of the water-cooled plate, effectively improving the docking success rate and the detection efficiency.

[0018] Embodiment: As Figures 1-3As shown in the figure, the utility model provides a plug-in device for detecting the water inlet of a water-cooled plate, including a bottom plate 1. A helium detection box 3 is fixedly connected to the top end of the bottom plate 1. An air outlet pipe 4 is fixedly connected to one end of the helium detection box 3. A fixing device 6 is slidably arranged on the top end of the bottom plate 1. A docking device 7 is fixedly connected to the top end of the bottom plate 1. The fixing device 6 includes two long plates 20 distributed in a mirror image. The bottom end of the lower long plate 20 is slidably connected to the top end of the bottom plate 1. Two long rods 18 are slidably arranged on the inner surface of the upper long plate 20. The two long rods 18 are jointly fixedly connected to the top end of the lower long plate 20, which can play a role in secondarily supporting the upper long plate 20 and making the device more stable. One end of each of the two long plates 20 is fixedly connected with a clamping block 5. Two pipe grooves 13 distributed in a mirror image are opened at the opposite ends of the two clamping blocks 5.

[0019] The air outlet pipe 4 and the center of one of the pipe grooves 13 are on the same horizontal line, which can make the pipe groove 13 accurately move to the outer surface of the air outlet pipe 4. The pipe groove 13 in front of the air outlet pipe 4 is used to fix the water inlet pipe of the water-cooled plate, and the other side is used to fix the water outlet pipe of the water-cooled plate.

[0020] Rubber soft pads 15 are fixedly arranged on the inner surfaces of the four pipe grooves 13, which can effectively avoid air leakage during detection and effectively improve the detection accuracy. Four telescopic air rods 2 are fixedly connected to the opposite ends of the two long plates 20. The opposite ends of every four adjacent telescopic air rods 2 are jointly fixedly connected with a clamping plate 11. A first motor 17 is fixedly connected to the top end of the bottom plate 1. The output end of the first motor 17 is fixedly connected with a gear 16. The outer surface of the gear 16 is meshed with a rack 12. One end of the rack 12 is fixedly connected with the upper clamping block 5. The rack 12 is slidably connected to one end of the lower clamping block 5.

[0021] The first motor 17 drives the gear 16 to rotate. The gear 16 drives the rack 12 to move. The rack 12 drives the upper clamping block 5 and the long plate 20 to move downward. Under the action of the two long plates 20, the two groups of telescopic air rods 2 can be driven to move. The two groups of telescopic air rods 2 drive the clamping plate 11 to fix the water-cooled plate.

[0022] The rack 12 can move more smoothly during movement. Two sliding rods 14 are fixedly connected to the top end of the lower clamping block 5. The outer surfaces of the two sliding rods 14 are jointly slidably sleeved with the inner surface of the upper clamping block 5.

[0023] The docking device 7 includes a support frame 21. One end of the support frame 21 is provided with a push plate 19. One end of the push plate 19 is fixedly connected to one of the long plates 20. The end of the push plate 19 away from the two long plates 20 is fixedly connected to a push rod 23. The bottom end of the push rod 23 is in contact with the top end of the bottom plate 1, which can play a role in supporting the push rod 23. Both ends of the push rod 23 are fixedly connected with two sliders 24. Slide grooves 26 for cooperating with the sliders 24 are provided on both inner walls of the support frame 21, which can make the push rod 23 move more smoothly and reduce the moving resistance. A long groove 22 is provided at the top end of the push rod 23. A rotating rod 25 is slidably connected to the inner surface of the long groove 22. The top end of the rotating rod 25 is rotatably sleeved on the upper inner wall of the support frame 21. A second motor 27 is provided at the top end of the support frame 21. The output end of the second motor 27 is fixedly connected to the top end of the rotating rod 25.

[0024] The second motor 27 can drive the rotating rod 25 to rotate. Under the action of the long groove 22, the rotating rod 25 can drive the push rod 23 to reciprocate, and the push rod 23 can drive the push plate 19 to reciprocate.

[0025] Working principle: When the water-cooled plate needs to be subjected to a sealing test, the water-cooled plate is placed between the two clamping plates 11. Then, the water inlet of the water pipe is placed in the pipe groove 13 on the same horizontal line as the air outlet pipe 4, and the water outlet of the water-cooled plate is placed in another pipe groove 13. The second motor 27 is turned on. The second motor 27 can drive the rotating rod 25 to rotate. Under the action of the long groove 22, the rotating rod 25 can drive the push rod 23 to reciprocate, and the push rod 23 can drive the push plate 19 to reciprocate. The push plate 19 can drive the lower long plate 20 to move. Then, under the action of the long plate 20, the entire fixing device 6 will be driven to move. When the pipe groove 13 on the same horizontal line as the air outlet pipe 4 moves to the outer surface of the water and gas pipe, the fixing device 6 is turned on for fixing.

[0026] When the water-cooled plate needs to be fixed, first seal the water outlet of the water-cooled plate. Then, the first motor 17 is turned on. The first motor 17 will drive the gear 16 to rotate. The gear 16 will drive the rack 12 to move. The rack 12 will drive the upper clamping block 5 and the long plate 20 to move downward. Under the action of the two long plates 20, the two groups of telescopic air rods 2 can be driven to move. The two groups of telescopic air rods 2 will drive the clamping plates 11 to fix the water-cooled plate. At the same time, the upper clamping block 5 will move downward and fix the water inlet of the water-cooled plate. Thus, the water inlet of the water-cooled plate and the air outlet pipe 4 can be fixed in the pipe groove 13. Under the action of the rubber soft pad 15, the device is not easy to leak air, improving the accuracy of the detection.
