Description

Technical Field

[0001] This utility model relates to the field of pressure testing fixture technology, and more specifically to a pressure testing fixture for radiator cores. Background Technology

[0002] The radiator core is a heat exchanger. When the engine is running, it generates a large amount of heat, raising the temperature of the coolant. The hot coolant flows into the radiator core and transfers heat to the fins or heat sinks through the cooling pipes. Air flows over the outside of the radiator core, absorbing heat from the fins or heat sinks, cooling the coolant and warming the air. This heat exchange helps maintain the engine within a suitable operating temperature range. During production, the radiator core undergoes a sealing test using a pressure testing fixture to check for leaks under a certain pressure. This ensures the quality and performance of the radiator core and prevents leaks such as water or air leaks during actual use, which could affect the radiator's heat dissipation effect and the normal operation of the entire system.

[0003] For example, a radiator core pressure testing fixture with prior art publication number CN222070028U collects water droplets falling from the radiator core through a perforated plate. The water droplets enter the test chamber through a perforated groove and a guide groove, achieving the effect of water conservation. Then, by running a fan, the radiator core can be quickly dried, making it more practical.

[0004] However, the existing technology described above still has the following problems in use: when the heat sink core moves above the drain plate, the dripping water droplets will splatter everywhere on the motherboard and drain plate, and under the blowing of the fan, the water droplets will also drift around, polluting the environment around the motherboard. Based on this, the present invention provides a heat sink core pressure testing fixture. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a radiator core testing fixture. It automatically transports radiator cores for testing using a clamping plate and a drive mechanism, resulting in high testing efficiency. A hot air blower and an air outlet are used to dry the radiator core with the blown air. Simultaneously, the cover plate and the testing chamber form a sealed space, effectively preventing water droplets from polluting the surrounding environment during drying. The entire testing fixture integrates testing and drying functions into one unit, is small in size, and occupies little space, thereby improving flexibility and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a radiator core pressure testing fixture, including a pressure testing chamber. The top of the pressure testing chamber is provided with a cover plate, and the bottom of the cover plate is provided with two symmetrically distributed clamping plates for conveying the radiator core for pressure testing. The outer walls of the two clamping plates are machined with multiple evenly distributed round holes. The bottom of the cover plate is provided with a driving mechanism for moving the two clamping plates. The inner wall of the pressure testing chamber is fixedly provided with multiple air outlets. The top of the cover plate is fixedly provided with a hot air blower. The hot air blower is connected to the multiple air outlets through an air supply pipe. Both sides of the pressure testing chamber are provided with lifting mechanisms for driving the cover plate to rise and fall.

[0007] In a preferred embodiment, the bottom of the cover plate is provided with a sliding groove, and the driving mechanism includes a lead screw that is rotatably disposed in the sliding groove. Two nut blocks are threadedly connected to the lead screw. The threads of the two nut blocks and the lead screw are opposite in direction, so that the two nut blocks move in opposite directions. With the cooperation of the lead screw and the nut blocks, the synchronous adjustment of the two clamping plates can be achieved.

[0008] In a preferred embodiment, two waterproof electric push rods are fixedly provided at the bottom of each of the two nut blocks. The bottom of the piston rods of the two waterproof electric push rods are fixed to the top of the clamping plate. The height of the clamping plate can be automatically adjusted by means of the waterproof electric push rods, so as to facilitate the rapid detection of the radiator core.

[0009] In a preferred embodiment, a servo motor is fixedly inserted through the side wall of the cover plate. One end of the output shaft of the servo motor passes through the cover plate and is fixed to the lead screw. The lead screw is driven to rotate by the servo motor, thereby improving the detection efficiency of the radiator core.

[0010] In a preferred embodiment, the lifting mechanism includes two waterproof electric push rods. Two fixing grooves are machined on both sides of the outer wall of the pressure test chamber. The two waterproof electric push rods are fixed in the two fixing grooves respectively. The cover plate is automatically driven to lift and lower by means of the waterproof electric push rods, thereby improving the testing efficiency of the radiator core.

[0011] In a preferred embodiment, the outer wall of the pressure test chamber is provided with multiple observation ports, each of which is fitted with tempered glass. The bottom inner wall of the pressure test chamber is set as an inclined surface. A drain valve is fixedly inserted through one side of the pressure test chamber. The drain valve is connected to the inside of the pressure test chamber. Opening the drain valve facilitates the drainage of water from the pressure test chamber, making it convenient to replace the water for testing.

[0012] In a preferred embodiment, a pressure relief valve is fixedly inserted through the top of the cover plate. The pressure relief valve is connected to the inside of the pressure test chamber and is located on the side of the hot air blower. The pressure relief valve can release air during the blowing and drying process to prevent excessive air pressure inside the pressure test chamber from causing danger.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention utilizes a clamping plate and a drive mechanism to automatically transport radiator cores for testing, resulting in high testing efficiency. It also employs a hot air blower and an air outlet to dry the radiator cores with the blown air. Simultaneously, the cover plate and the pressure test chamber form a sealed space, effectively preventing water droplets from leaking out and polluting the surrounding environment during drying. The entire pressure test fixture integrates testing and drying functions into one unit, is small in size, and occupies little space, thereby improving flexibility. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the attached diagram in the instruction manual. Figures 1-5This utility model provides a pressure testing fixture for radiator cores, including a pressure testing chamber 1. The pressure testing chamber 1 has a cover plate 2 on top, and two symmetrically distributed clamping plates 3 at the bottom of the cover plate 2 for conveying the radiator core for pressure testing. The outer walls of the two clamping plates 3 are machined with multiple evenly distributed round holes 4. The bottom of the cover plate 2 is provided with a driving mechanism 5 for driving the two clamping plates 3 to move. Specifically, the bottom of the cover plate 2 has a sliding groove 9. The driving mechanism 5 includes a lead screw 51, which is rotatably disposed in the sliding groove 9. Two nut blocks 52 are threadedly connected to the lead screw 51. The threads of the two nut blocks 52 and the lead screw 51 have opposite directions, so that the two nut blocks 52 move in opposite directions. Two waterproof electric push rods 53 are fixedly provided at the bottom of the two nut blocks 52. The bottom ends of the piston rods of the two waterproof electric push rods 53 are fixed to the top of the clamping plates 3. A servo motor 54 is fixedly inserted through the side wall of the cover plate 2. One end of the output shaft of the servo motor 54 passes through the cover plate 2 and is fixed to the lead screw 51.

[0025] like Figure 3 As shown, multiple air outlets 6 are fixedly installed on the inner wall of the pressure test chamber 1. Specifically, there are four air outlets 6, which are respectively fixed on the inner wall surface of the pressure test chamber 1. A hot air blower 7 is fixedly installed on the top of the cover plate 2. The hot air blower 7 is connected to the multiple air outlets 6 through an air supply pipe. Both sides of the pressure test chamber 1 are provided with lifting mechanisms 8 for driving the cover plate 2 to rise and fall. Specifically, the lifting mechanism 8 includes two waterproof electric push rods 81. Two fixing grooves 82 are machined on both outer walls of the pressure test chamber 1. The two waterproof electric push rods 81 are respectively fixed in the two fixing grooves 82. The cover plate 2 is automatically driven to rise and fall by means of the waterproof electric push rods 81, thereby improving the testing efficiency of the radiator core.

[0026] In actual use, firstly, the four waterproof electric push rods 281 extend to drive the cover plate 2 to rise. After the operator places the radiator core to be tested between the two clamping plates 3, the waterproof electric push rods 281 are used to drive the cover plate 2 to descend and fit against the top of the pressure test chamber 1. Then, the waterproof electric push rods 153 extend to drive the clamping plates 3 and the radiator core to sink into the water at the bottom of the inner cavity of the pressure test chamber 1. When there are gaps inside the radiator core, air bubbles will be generated, indicating that the radiator core is unqualified; otherwise, the radiator core is qualified. After the test, the waterproof electric push rod 53 lifts the radiator core out of the water, allowing the water droplets on the radiator core to drip off again. The hot air blower 7 then blows air into multiple air outlets 6 to dry the water droplets on the radiator core. This prevents water droplets from polluting the surrounding environment during material unloading. At the same time, the cover plate 2 at the top of the test chamber 1 acts as a seal to prevent water droplet leakage. The entire test fixture integrates testing and drying functions into one unit, with a small size and small footprint, thus improving flexibility.

[0027] Refer to the attached diagram in the instruction manual. Figures 1-5 The outer wall of the pressure test chamber 1 is provided with multiple observation ports 10, and each observation port 10 is fixedly provided with tempered glass 11, so that the staff can observe the inside of the pressure test chamber 1 in real time. The bottom inner wall of the pressure test chamber 1 is set as a slope. A drain valve 12 is fixedly inserted through one side of the pressure test chamber 1. The drain valve 12 is connected to the inside of the pressure test chamber 1. Opening the drain valve 12 makes it easy to drain the water in the pressure test chamber 1, so that the water can be replaced and tested again.

[0028] A pressure relief valve 13 is fixedly inserted through the top of the cover plate 2. The pressure relief valve 13 is connected to the inside of the pressure test chamber 1 and is located on one side of the hot air blower 7. The pressure relief valve 13 can release air during the blowing and drying process to prevent the pressure inside the pressure test chamber 1 from becoming too high and causing danger.
