Description

Technical Field

[0001] This utility model relates to the field of compressor testing technology, and in particular to a performance testing device for automotive air conditioning compressors. Background Technology

[0002] The automotive air conditioning compressor is the heart of the air conditioning refrigeration system, providing the power to maintain the circulation of refrigerant within the system. Its function is to keep the refrigerant circulating. The compressor draws in refrigerant vapor from the low-pressure side, pressurizes the refrigerant, and then discharges it to the condenser. The compressor's performance indicators mainly include displacement, cooling capacity, input power, net mass, and volumetric efficiency. To evaluate the performance of an automotive air conditioning compressor, verify whether the product meets design requirements, and ensure compatibility between the compressor and the air conditioner, it is necessary to know the compressor's performance parameters, namely its cooling capacity, input power, and changes in performance parameters at different speeds. To test the relevant parameters of the automotive air conditioning compressor before it leaves the factory, and thus reflect whether the overall performance of the compressor meets factory requirements, it is necessary to simulate the compressor's operating state. Therefore, automotive air conditioning compressor performance testing equipment is required to test the compressor's performance.

[0003] Existing automotive air conditioning compressor performance testing equipment typically involves first connecting the compressor under test to the equipment. After the test is completed, the tested compressor needs to be removed from the equipment and taken out of the storage platform. Then, another compressor under test needs to be taken out and transported to the testing position of the equipment for pipeline connection. This back-and-forth disassembly and installation process greatly reduces the efficiency of compressor factory testing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing automotive air conditioning compressor performance testing equipment. Typically, when testing a compressor, the compressor under test is first connected to the equipment. After the test is completed, the tested compressor needs to be removed from the equipment, and another compressor under test needs to be taken from the storage platform and transported to the testing position of the equipment for pipe connection. This back-and-forth disassembly and installation process significantly reduces the efficiency of compressor factory testing. Therefore, this invention proposes an automotive air conditioning compressor performance testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automotive air conditioning compressor performance testing device includes a housing and a condenser assembly, an evaporator assembly, and an electronic expansion valve mounted on the housing. A support plate for placing products is installed inside the housing. A connecting frame is provided at the bottom of the support plate. The connecting frame and the housing are slidably connected via a damping slide rail and a first slider. A clamping assembly for fixing products is mounted on the support plate. The clamping assembly includes a base plate, a first slide groove, and a bidirectional lead screw installed within the first slide groove. Slide seats are fitted at both ends of the bidirectional lead screw, and irregularly shaped clamping components are connected to the slide seats.

[0007] Furthermore, the irregularly shaped clamping component includes a clamping plate, the inner surface of which has a groove, and a fixing post is adhered to the groove.

[0008] Furthermore, a movable sleeve is fitted at the end of the fixed column, and an elastic element is bonded to the inner end of the movable sleeve. The movable sleeve and the fixed column form an elastic structure through the elastic element.

[0009] Furthermore, a damping plate is provided between the damping slide rail and the first slider, and the damping plate is detachably connected to the inner walls of both sides of the damping slide rail.

[0010] Furthermore, the support plate has a second U-shaped sliding groove, a limiting groove is provided on the bottom side of the second sliding groove, and a spacer plate is installed in the middle section of the arc-shaped part of the second sliding groove.

[0011] Furthermore, the second slide groove and the second slider are slidably connected. The second slider has a cylindrical structure and is provided with embedded balls on its outside. The outer wall of the embedded balls is in contact with the inner wall of the second slide groove.

[0012] Furthermore, both ends of the bidirectional lead screw are connected to adjustment handles through the base plate, and a rubber ring is provided at the connection between the bidirectional lead screw and the second slide groove to limit the position.

[0013] Furthermore, a rotating component is provided between the support plate and the second slider, and an inlet opening is provided in the middle of the support plate.

[0014] Furthermore, the housing is equipped with industrial control components, including an industrial computer. The industrial computer contains a PLC controller connected to the condenser assembly, the evaporator assembly, and the electronic expansion valve. Four sets of cabinet doors are distributed on the outside of the housing, and a movable door is installed at the bottom of one of the cabinet doors located in the direction of the damping slide rail.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, by setting up a support plate and clamping components, after the compressor inside the equipment completes the testing operation, the equipment pipeline connected to it is disassembled and directly installed on another compressor on the support plate. Furthermore, by operating the two sets of clamping components to switch positions, the next compressor can be tested. This structural design greatly saves the time required to pick up and drop products back and forth between the pre-test and post-test products, improves the product manufacturing efficiency, and has high practicality.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 A performance testing device for an automotive air conditioning compressor includes a housing 1 and a condenser assembly 2, an evaporator assembly 4, and an electronic expansion valve 3 mounted on the housing 1. The housing 1 contains a support plate 13 for placing products. A connecting frame 7 is provided at the bottom of the support plate 13. The connecting frame 7 and the housing 1 are slidably connected via a damping slide rail 6 and a first slider 8. A clamping assembly 10 for fixing products is mounted on the support plate 13. The clamping assembly 10 includes a base plate 1001, a first slide groove 1002, and a bidirectional lead screw 1003 installed within the first slide groove 1002. Slide seats 1004 are fitted at both ends of the bidirectional lead screw 1003, and irregularly shaped clamping members 17 are connected to the slide seats 1004.

[0027] By adopting the above technical solution, through the action of the two sets of clamping components 10 on the support plate 13, after a set of products in the equipment completes the testing operation, the equipment pipeline is disconnected from the product, and the corresponding equipment pipeline is connected to another set of products to be tested. Then, the tested product is removed from the equipment, and the product to be tested with the pipeline connected is pushed into the equipment for testing. This design helps to save the time that workers need to walk back and forth to pick up and put down products between disassembling the previous set and assembling the next set of products, greatly shortens the time for changing products, improves the factory's production efficiency, and has high practicality.

[0028] Furthermore, the electronic expansion valve 3 is installed on the connecting pipe between the condenser assembly 2 and the evaporator assembly 4, so that the refrigerant cooled by the condenser assembly 2 can undergo pressure reduction and temperature reduction through the expansion valve. The structure and principle of the condenser assembly 2 and the evaporator assembly 4 are the same as those of the prior art or can be implemented by the prior art, and will not be described in detail here.

[0029] The irregular clamping component 17 includes a clamping plate 1701, the inner surface of which is provided with a groove 1702, and a fixing post 1703 is bonded to the groove 1702.

[0030] Furthermore, the irregularly shaped clamping component 17 provides stable clamping for the product under test, ensuring that the product on the carrier plate 13 will not shift or fall off during the movement of the carrier plate 13, thus preventing any disruption to the smooth progress of the product testing operation.

[0031] A movable sleeve 1704 is fitted at the end of the fixed column 1703. An elastic element 1705 is bonded to the inner end of the movable sleeve 1704. The movable sleeve 1704 and the fixed column 1703 form an elastic structure through the elastic element 1705.

[0032] By adopting the above technical solution, specifically, the elastic element 1705 uses a spring and / or spring sheet, so that the movable sleeve 1704 and the elastic element 1705 can abut against the uneven surface of the product, thereby clamping the product and preventing the product from shifting or falling off during movement, which has high practicality.

[0033] A damping plate 9 is provided between the damping slide rail 6 and the first slider 8, and the damping plate 9 is detachably connected to the inner walls of both sides of the damping slide rail 6.

[0034] By adopting the above technical solution, the material of the damping plate 9 can be rubber, polyurethane, silicone, etc., so that the connecting frame 7 and the bearing plate 13 can effectively absorb the vibration and impact in the mechanical system when they are pulled out. According to the characteristics of the damping material, the thicker and harder the material, the better the damping effect.

[0035] The bearing plate 13 has a second sliding groove 12 in a U-shaped structure. The bottom side of the second sliding groove 12 is provided with a limiting groove. A partition plate 18 is installed in the middle section of the arc-shaped part of the second sliding groove 12.

[0036] By adopting the above technical solution and setting the second slide 12, the two sets of clamping components 10 can change positions on the support plate 13. This facilitates the direct connection of the equipment's pipeline to the next compressor product after the previous compressor product has completed testing, and the position can be changed. This saves the time that workers need to walk back and forth to pick up and put down products between disassembling the previous set and assembling the next set of products. The products in the reserved positions can be installed with the equipment's pipeline in advance, which greatly shortens the time for changing products and helps to improve the factory's production efficiency.

[0037] The second slide groove 12 and the second slider 15 are slidably connected. The second slider 15 has a cylindrical structure and is provided with embedded balls 11 on the outside. The outer wall of the embedded balls 11 is in contact with the inner wall of the second slide groove 12.

[0038] By adopting the above technical solution, the second slider 15, through the setting of embedded ball bearings 11, makes the sliding between the second slider 15 and the second slide groove 12 smoother, thereby enabling the position exchange of the two sets of clamping components 10 to be carried out smoothly.

[0039] Both ends of the bidirectional lead screw 1003 pass through the base plate 1001 and are connected to the adjustment handle 1005. A rubber ring is provided at the connection between the bidirectional lead screw 1003 and the second slide groove 12 to limit the position.

[0040] By adopting the above technical solution, the setting of the double-headed adjustment handle 1005 allows both ends of the clamping assembly 10 to rotate the bidirectional lead screw 1003 by operating the adjustment handle 1005, so that the two sets of slides 1004 on the bidirectional lead screw 1003 can move relative to each other, thereby adjusting the irregular clamping member 17 and providing clamping work for the test product.

[0041] A rotating component 14 is provided between the support plate 13 and the second slider 15, and a wire inlet opening 16 is provided in the middle of the support plate 13.

[0042] Specifically, the rotating component 14 can be a rotating damper (the specific structure of the rotating damper can be easily implemented by those skilled in the art based on relevant technologies, and will not be described in detail here). Before placing the product, the two sets of clamping components 10 are moved to the front section (inside the equipment) and the rear section (outside the equipment) of the support plate 13, respectively. The product to be tested is placed on the two sets of clamping components 10 and fixed. By cooperating with the rotating component 14, the clamping components 10 at the front and rear sections are rotated from the vertical direction to the horizontal direction, which facilitates the subsequent closing of the cabinet door 101 and the testing of the equipment's compressor. At this time, the product to be tested is located outside the equipment.

[0043] The housing 1 is equipped with an industrial control component 5, which includes an industrial computer. The industrial computer contains a PLC controller connected to the condenser assembly 2, the evaporator assembly 4, and the electronic expansion valve 3. When the product to be tested is connected to the equipment's testing pipeline, the industrial control component 5 is operated to activate the various components of the equipment (structures not described in this utility model are the same as or can be implemented using existing technology and are therefore not elaborated here) to perform product testing. The housing 1 has four sets of cabinet doors 101 distributed on its exterior, including one cabinet door 101 located in the sliding direction of the damping slide rail 6. The bottom is equipped with a movable door 102. Specifically, the movable door 102 has a corresponding storage slot at the handle position of the cabinet door 101. Magnetic components are installed at the corresponding positions of the storage slot and the handle (the specific structure of the magnetic components can be easily implemented by those skilled in the art based on relevant technologies, and will not be elaborated here). When the movable door 102 is opened, the magnetic components overlap to fix the open state of the movable door 102. The movable door 102 is an upward-flipping opening method, providing space for the compressor stored outside the equipment, and avoiding interference with the closing operation of the cabinet door 101 when the first set of compressors is being tested due to the presence of the compressor to be tested outside the equipment.

[0044] Working principle: By manually opening the cabinet door 101 of the housing 1 located in the sliding direction of the damping slide rail 6, the bearing plate 13 and connecting frame 7, along with the first slider 8, are pulled out of the damping slide rail 6, so that most of the bearing plate 13 is outside the housing 1. Then, the product to be tested (in this embodiment, the product being tested is a vehicle compressor) is manually fixed onto the clamping assembly 10. The irregularly shaped clamping parts 17 on the clamping assembly 10 provide clamping action for products with uneven surfaces. Then, the testing pipeline of the equipment is connected to the corresponding port of the compressor. After the compressor testing is completed, the... The equipment pipeline and compressor are disassembled, and the equipment pipeline is directly connected to another set of clamped compressors to be tested on the support plate 13. Then, the tested product is removed from the equipment with the second slide 12. At this time, the clamping assembly 10 with the compressor is pushed into the equipment for testing. This design helps to save the time that workers need to walk back and forth to pick up and put down products between disassembling the previous set and assembling the next set of products. After disassembling the previous set of compressors, the equipment pipeline can be directly installed with the other set of compressors, which greatly shortens the time for changing products and has high practicality.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
