Description

Technical Field

[0001] This utility model relates to the technical field of pressure testing devices for water tanks, specifically a multi-station pressure testing frame for radiator water tanks. Background Technology

[0002] After production, automotive radiators typically undergo airtightness testing to prevent leaks during use and ensure compliance with factory requirements. Currently, the pressure testing process usually requires transferring radiators from the production line to the testing station. Radiators that pass the pressure test are then stored in a unified warehouse. The testing station is not well-suited to the production line, resulting in lengthy transfer times and impacting testing efficiency. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a multi-station pressure testing frame for a heat dissipation water tank.

[0004] The technical solution of this utility model is as follows:

[0005] A multi-station pressure testing frame for a heat dissipation water tank includes a main frame and multiple sets of pressure testing devices arranged linearly on it, and the pressure testing of water tanks on the production line can be completed through the multiple sets of pressure testing devices.

[0006] As the core technical concept of this utility model, the pressure testing device includes a lifting mechanism, a fixing mechanism, and a pressure testing mechanism arranged sequentially from bottom to top. The main frame can be passed through by the production line. The lifting mechanism includes a lifting plate that can be set under the production line and can lift the pallet on the production line. The fixing mechanism includes two fixing arms arranged opposite each other, which are configured to clamp and fix the pallet lifted by the lifting plate. The pressure testing mechanism includes an inflation unit that can inflate the water tank on the pallet and a detection unit that can detect the gas pressure inside the water tank. Based on the above structure, the pressure testing frame (the above-mentioned multi-station pressure testing frame for a radiator water tank) is... This system allows for better integration with the production line. When the production line moves the pallet to transport the water tank to the lifting mechanism, the lifting plate lifts the pallet and the water tank, and the fixing arm of the fixing mechanism secures the pallet. Then, the water tank is manually pressure tested on the pallet using the pressure testing mechanism. After the pressure test is completed, the pallet and the water tank are returned to the production line using the lifting plate. By controlling the lifting plate to complete one lift and then immediately reset, interference between the production line operation and the lifting plate's movement is prevented. This ensures that the water tank pressure test on the production line can be carried out more smoothly and sequentially through multiple pressure testing mechanisms, significantly improving the pressure testing efficiency.

[0007] As described above, the multi-station pressure test frame for a radiator includes a main rod with a telescopic cylinder on it. The telescopic end of the telescopic cylinder is equipped with a support plate. By controlling the movement of the support plate through the telescopic cylinder, it can cooperate with the support plate that lifts the lifting plate to clamp and fix it.

[0008] As a preferred embodiment, to ensure the clamping and fixing effect of the support strip on the pallet, the support strip has an "L" shaped cross section. Its horizontal part can support the lower side of the pallet, and its vertical part can clamp and fix it to both sides of the pallet, thereby ensuring the fixing effect on the pallet and preventing the pallet from shaking during the pressure test.

[0009] As a further preferred embodiment, in order to reduce the space occupied by the fixed arm and thus reduce the space requirement for the single set of pressure testing devices, the telescopic cylinder is located inside the main body rod, with its telescopic end extending from one side of the main body rod and connected to the support plate.

[0010] To further describe the structure of the fixed arm, the main rod includes a strip-shaped receiving box with an opening at the top. The telescopic cylinder is located inside the receiving box, and its telescopic end protrudes from one side of the receiving box. A sealing cover is fastened to the top of the receiving box to ensure the ease of deployment of the telescopic cylinder.

[0011] Preferably, to further ensure the fixing effect of the support plate by the fixing arm, multiple telescopic cylinders are linearly arranged on the same main body rod.

[0012] As described above, in terms of the structure of the multi-station pressure testing frame for a heat dissipation tank, the inflation unit includes an air pump and an inflation head. The detection unit is connected to the air pump and the inflation head pipe. By connecting the inflation head and the water tank, the detection unit can inject air at a preset pressure into the water tank and detect the changes in gas pressure in the water tank in real time, thus completing the pressure test of the water tank's sealing performance. In order to facilitate the temporary storage of the inflation head after the pressure test of a single water tank is completed, and to prevent it from interfering with the transportation of the production line, the main frame or fixed arm is also provided with a placement box for placing the inflation head.

[0013] As described above, in order to ensure that the production line can continue to operate without affecting the pressure testing work and to reduce the control requirements for the transportation work of the production line, a limiting mechanism is also provided on one side of the lifting mechanism to stop the pallet on the production line.

[0014] The beneficial effects of this utility model are as follows: This utility model is a multi-station pressure testing frame for heat dissipation water tanks, which can be better adapted to the production line. When the production line moves the pallet to transport the water tank to the lifting mechanism, the lifting plate can lift the pallet and the water tank on it, and the pallet is fixed by the fixing arm of the fixing mechanism. Then, the manual pressure testing of the water tank is completed on the pallet by the pressure testing mechanism. After the pressure test is completed, the pallet and the water tank on it are put back on the production line by the lifting plate. By controlling the lifting plate to complete one lift and then immediately reset, the operation of the production line and the movement of the lifting plate are prevented from interfering with each other. This ensures that the pressure testing of the water tank on the production line can be carried out more smoothly in sequence by multiple sets of pressure testing mechanisms, which significantly improves the pressure testing efficiency.

[0025] Example

[0026] This embodiment provides a multi-station pressure testing frame for a heat dissipation water tank. (See also...) Figure 1 and Figure 2 It includes the main frame 1 and multiple sets of pressure testing devices arranged linearly on it. The pressure testing of water tanks on the production line can be completed through the multiple sets of pressure testing devices. The structure of the pressure testing frame will be described in detail below with reference to the attached drawings.

[0027] In this embodiment, as the core technical concept of this utility model, the pressure testing device includes a lifting mechanism 2, a fixing mechanism 4, and a pressure testing mechanism 5 arranged sequentially from bottom to top. The main frame 1 can be passed through by the production line. The lifting mechanism 2 is configured to lift the pallet on the production line, and the fixing mechanism 4 can complete the fixing of the pallet lifted by the lifting mechanism 2. Finally, the water tank can be pressure tested manually on the pallet through the pressure testing mechanism 5.

[0028] Firstly, regarding the structure of the lifting mechanism 2, in conjunction with... Figure 3 The lifting mechanism 2 includes a lifting plate 21 that can be installed on the lower side of the production line and can lift the pallets on the production line, and a drive unit that can drive the lifting plate 21 to rise and fall.

[0029] Specifically, the main frame 1 includes a frame 11, in which multiple fixed plates 12 are horizontally arranged corresponding to multiple sets of pressure testing devices. The support plate is designed to pass over the fixed plates 12 under the drive of the production line. The lifting plate 21 is horizontally arranged on the upper side of the fixed plates 12, and multiple sliding rods 22 are vertically arranged on its lower side. The sliding rods 22 are vertically slidably connected to the fixed plates 12. One of the sliding rods 22 has a threaded structure. A lifting motor 23 is arranged on the lower side of the fixed plate 12 corresponding to its position. The lifting motor 23 and the threaded sliding rod 22 cooperate to complete the lifting and lowering drive of the lifting plate 21. As for the specific cooperation method between the motor and the threaded sliding rod 22, a threaded cylinder can be rotatably arranged on the lower side of the fixed plate 12, and the threaded sliding rod 22 is helically engaged with the threaded cylinder. The motor drives the rotation of the threaded cylinder to drive the lifting and lowering of the lifting plate 21. Of course, the motor and the threaded sliding rod 22 can also have other transmission cooperation methods. The specific transmission cooperation method is not limited here.

[0030] Regarding the structure of the fixing mechanism 4, in conjunction with Figure 4 and Figure 5 The fixing mechanism 4 includes two fixing arms 41 that are arranged opposite to each other and perpendicular to the linear arrangement direction of the multiple sets of pressure testing devices. The two fixing arms 41 are configured to clamp and fix the lifting plate 21.

[0031] Specifically, the fixed arm 41 includes a horizontal main rod whose arrangement direction is perpendicular to the linear arrangement direction of multiple sets of pressure testing devices. The main rod is equipped with a telescopic cylinder 414, and the telescopic end of the telescopic cylinder 414 is equipped with a support plate 415. The telescopic cylinder 414 can control the movement of the support plate 415, thereby clamping and fixing the pallet lifted by the lifting plate 21.

[0032] As a preferred embodiment, in order to reduce the space occupied by the fixed arm 41 and thus reduce the space requirement for the single set of pressure testing devices, the telescopic cylinder 414 is located inside the main body rod, and its telescopic end extends out from one side of the main body rod and is connected to the support strip 415.

[0033] Specifically, regarding the arrangement of the telescopic cylinder 414, the main rod includes a strip-shaped receiving box 411 with an open top. A vertical strip plate 413 with a straight surface is provided at the bottom center of the receiving box 411 along its length. The telescopic cylinder 414 is located inside the receiving box 411 and fixed to one side of the vertical plate 413. An opening is provided on one side of the receiving box 411 corresponding to the telescopic cylinder 414. The telescopic end of the telescopic cylinder 414 extends through the opening on one side of the receiving box 411. A sealing cover 412 is also fastened to the upper end of the receiving box 411 to ensure the ease of installation of the telescopic cylinder 414.

[0034] To further reduce the space requirements for the pressure testing device, two adjacent pressure testing devices share a fixed arm 41. Specifically, several fixed arms 41 of multiple pressure testing devices are arranged linearly. Among the several fixed arms 41 of multiple pressure testing devices, the fixed arms 41 located at both ends along the linear arrangement direction of the pressure testing devices are the first fixed arms, and the fixed arms 41 located between the two first fixed arms 41 are the second fixed arms. A telescopic cylinder 414 is provided on one side of the vertical plate 413 inside the main body of the first fixed arm, and telescopic cylinders 414 are provided on both sides of the vertical plate 413 inside the main body of the second fixed arm.

[0035] As a further preferred embodiment, to ensure the clamping and fixing effect of the support strip 415 on the pallet, the support strip 415 has an "L" shaped cross section. Its horizontal part can support the lower side of the pallet, and its vertical part can clamp and fix it to both sides of the pallet, thereby ensuring the fixing effect of the pallet and preventing the pallet from shaking during the pressure test.

[0036] Preferably, to further ensure the fixing effect of the support plate by the fixing arm 41, multiple telescopic cylinders 414 are linearly arranged on the same main body rod.

[0037] Finally, regarding the structure of the pressure testing mechanism 5, it includes an inflation unit capable of inflating the water tank on the pallet, and a detection unit capable of detecting the gas pressure inside the water tank. Based on the above structure, the pressure testing frame can be better adapted to the production line. When the production line moves the pallet and transports the water tank to the lifting mechanism 2, the lifting plate 21 can lift the pallet and the water tank on it, and the pallet is fixed by the fixing arm 41 of the fixing mechanism 4. Then, the manual pressure testing of the water tank is completed on the pallet by the pressure testing mechanism 5. After the pressure test is completed, the pallet and the water tank on it are put back onto the production line by the lifting plate 21. By controlling the lifting plate 21 to complete one lift and then immediately reset, the operation of the production line and the movement of the lifting plate 21 are prevented from interfering with each other. This ensures that the pressure testing of the water tank on the production line can be carried out more smoothly in sequence by multiple sets of pressure testing mechanisms 5, which significantly improves the pressure testing efficiency.

[0038] Specifically, the inflation unit includes an air pump and an inflation head (not shown in the figure). The detection unit includes a main body box located on the upper side of the frame 11, which contains a control valve connected to the air pump and the inflation head pipe, as well as a pressure sensor capable of detecting gas pressure. By connecting the inflation head and the water tank, under the combined action of the control valve and the pressure sensor in the detection unit, air at a preset pressure can be injected into the water tank, and the changes in gas pressure in the water tank can be detected in real time to complete the pressure test of the water tank's sealing performance. Of course, the inflation operation and the detection of gas pressure can also be implemented in other ways, which are not specifically limited here.

[0039] As a preferred embodiment, in order to facilitate the temporary storage of the inflation head after a single water tank is pressurized, and to prevent it from interfering with the transportation of the production line, the main frame 1 or the fixed arm 41 is also provided with a placement box 6 for placing the inflation head.

[0040] In this embodiment, in order to ensure that the production line can operate continuously without affecting the pressure testing and inspection work, and to reduce the control requirements for the transportation work of the production line, a limiting mechanism 3 that can stop the pallets on the production line is also provided on one side of the lifting mechanism 2.

[0041] Specifically, the limiting mechanism 3 includes a lifting motor mounted on the frame 11 and located on the side of the corresponding lifting mechanism 2 along the transport direction of the transport line. Its upper end is a transmission end and is equipped with a stop. When the pallet carried by the transfer line reaches the corresponding lifting mechanism 2, the lifting motor can drive the stop to rise to stop the pallet. Finally, the lifting mechanism 2 can smoothly lift the pallet. The specific working sequence or principle of the limiting mechanism 3 should be determined according to the detection of multiple sets of pressure testing devices. The specific control method or sequence will not be elaborated here.
