[0002] The automobile air conditioning compressor is one of the core components of the automobile air conditioning system. It is a mechanical device that compresses, condenses, and evaporates gas.

[0039] Reference Figures 1 to 5As shown, an automobile air-conditioning compressor detection device according to an embodiment of the utility model comprises: a frame 200, two fixing mechanisms 300, an adapter 400, a driving unit 500, and a refrigerant storage mechanism 600; a working platform plate is arranged at the top of the frame 200. The two fixing mechanisms 300 are symmetrically connected to the frame 200, and the two fixing mechanisms 300 are both located above the working platform plate. The installation space of the compressor 100 is defined between the two fixing mechanisms 300, and the two fixing mechanisms 300 cooperate to clamp the compressor 100 in the left and right directions to limit the horizontal position of the compressor 100; the adapter 400 is rotatably mounted on the frame 200, and the rotation axis of the adapter 400 is arranged vertically. The adapter 400 is used to connect the input shaft of the compressor 100; the rotation direction of the input shaft of the compressor 100 is also vertical, and the driving unit 500 is installed on the frame 200, and the driving unit 500 is located below the working platform plate. The driving part 500 uses a three-phase asynchronous motor 320, and the driving part 500 is used to drive the adapter 400 to rotate. The refrigerant storage mechanism 600 is connected to the inlet and outlet of the compressor 100 through two hoses 630, and the refrigerant storage mechanism 600 is used to input refrigerant to the compressor 100 and receive the refrigerant output by the compressor 100. If the compressor 100 can work normally, when the input shaft of the compressor 100 is driven to rotate by the driving part 500, the refrigerant should be sucked from the inlet of the compressor 100 and discharged from the outlet of the compressor 100. The temperature and pressure of the refrigerant discharged from the outlet of the compressor 100 should be greater than the temperature and pressure of the refrigerant sucked from the inlet of the compressor 100. The difference in temperature and pressure represents the working efficiency of the compressor 100. When the speed of the adapter 400 remains unchanged, the greater the temperature difference between the refrigerant discharged from the outlet of the compressor 100 and the refrigerant sucked into the inlet of the compressor 100, the better the working state of the compressor 100 is, and the higher the utilization value is. When the speed of the adapter 400 remains unchanged, the greater the pressure difference between the refrigerant discharged from the outlet of the compressor 100 and the refrigerant sucked into the inlet of the compressor 100, the better the working state of the compressor 100 is, and the higher the utilization value is. By fixing the compressor 100 by the fixing mechanism 300 and driving the compressor 100 to work by the adapter 400, various types of compressors 100 can be tested quickly, thereby improving the detection efficiency.

[0040] Reference Figures 1 to 4As shown, it can be understood that the fixing mechanism 300 includes a guide part 310, a motor 320, and a horizontal cylinder 330. The guide part 310 is vertically welded above the working platform plate, and a slide groove is vertically opened in the guide part 310. A slider 311 is slidably connected inside the guide part 310, and the slider 311 is embedded in the slide groove. The slide groove limits the slider 311 so that the slider 311 cannot rotate, and the slider 311 can only move in the up and down directions. The motor 320 is fixedly connected to the guide part 310, and the motor 320 is bolted to the upper end of the guide part 310, and the output shaft of the motor 320 is connected to the screw 321. It can be foreseen that the output shaft of the motor 320 is connected to the reducer, and the reducer is connected to the screw 321. The reducer can be a common gear reducer. By increasing the torque of the motor 320 through the reducer, the rotation control accuracy of the motor 320 can also be improved. The screw 321 is vertically arranged and threadedly connected to the slider 311, and the screw 321 is rotatably installed in the center of the slide groove. The fixed end of the horizontal cylinder 330 is bolted to the side wall of the slider 311, and a vertical avoidance groove is provided on the side wall of the guide part 310, through which the fixed end of the horizontal cylinder 330 passes. The telescopic end of the horizontal cylinder 330 can be extended to abut against the compressor 100 located in the installation space to fix the compressor 100. A pressure block is connected to the telescopic end of the horizontal cylinder 330, and the shape and size of the pressure block match the external shape of the compressor 100. The pressure blocks connected by the two fixing mechanisms 300 are respectively abutted against the compressor 100 from the left and right sides to fix the compressor 100. The fixing mechanism 300 fixes the compressor 100 from different positions through the movement of the motor 320 and the horizontal cylinder 330, and can adapt to compressors 100 of various sizes. No manual operation is required in the process of fixing the compressor 100, which effectively reduces the labor intensity of the operator.

[0041] Reference Figures 1 to 4 As shown, it can be understood that an electric chuck 410 is provided at the upper end of the adapter 400. The specific structure of the electric chuck 410 is prior art, so it will not be described in detail. The electric chuck 410 can clamp the input shaft of the compressor 100 to drive the input shaft of the compressor 100 to rotate. A pulley is usually provided on the input shaft of the compressor 100. The pulley on the input shaft of the compressor 100 is fixed by the electric chuck 410. It has wide applicability and is convenient and quick to fix. The operator only needs to put the input shaft of the compressor 100 on the electric chuck 410, and the electric chuck 410 can be clamped to complete the fixation and centering. The labor intensity of the operator is effectively reduced.

[0042] Reference Figures 1 to 5As shown, it can be understood that the adapter 400 is rotatably mounted on the frame 200 through the radial bearing 420 and the thrust bearing 430. The radial bearing 420 and the thrust bearing 430 form a bearing group to reduce the friction when the adapter 400 rotates. A boss is provided on the working platform plate, and a center hole for the output shaft of the driving unit 500 to pass through is provided in the center of the boss, and a radial bearing 420 is sleeved on the outer peripheral wall of the boss. The radial bearing 420 can be a ball bearing. A first circular groove for the radial bearing 420 to be embedded is provided at the lower end of the adapter 400. The thrust bearing 430 uses a deep groove ball bearing, and a second circular groove is provided in the first circular groove. The thrust bearing 430 is arranged in the second circular groove, and the lower end of the thrust bearing 430 is against the boss, and the upper end of the thrust bearing 430 is against the top wall of the second circular groove. The radial bearing 420 and the thrust bearing 430 form a bearing group to reduce the friction and vibration when the adapter 400 rotates.

[0043] Reference Figure 5 As shown, it can be understood that the driving part 500 is connected to the adapter part 400 by a spline. The spline connection is convenient for disassembly and assembly. The driving part 500 is installed on the motor frame 200, and the motor frame 200 is bolted to the bottom of the working platform plate. When disassembling and assembling the driving part 500, only the motor frame 200 and the driving part 500 need to be disassembled and assembled as a whole. It is convenient for installation and maintenance.

[0044] Reference Figures 1 to 5 As shown, it can be understood that the refrigerant storage mechanism 600 includes a first storage tank 610 and a second storage tank 620, both of which are stainless steel tanks, and the first storage tank 610 and the second storage tank 620 are connected to the inlet and outlet of the compressor 100 through two hoses 630, respectively, and the hoses 630 are fixed to the inlet and outlet of the compressor 100 through stainless steel hose clamps. The first storage tank 610 and the second storage tank 620 are connected through a balance pipe 640, and a balance valve 641 is provided on the balance pipe 640. When the compressor 100 is running, the refrigerant in the first storage tank 610 will be transferred to the second storage tank 620. Therefore, the pressure difference between the first storage tank 610 and the second storage tank 620 will become larger and larger. When the pressure difference between the first storage tank 610 and the second storage tank 620 reaches a preset value, the balance valve 641 opens to allow the refrigerant in the second storage tank 620 to flow to the first storage tank 610 until the pressure between the first storage tank 610 and the second storage tank 620 is equal.

[0045] Reference Figures 1 to 5As shown, it can be understood that the first storage tank 610 and the second storage tank 620 are both connected to a temperature stabilizer, and the temperature stabilizer can be a combination of a heat sink and a heat dissipation fan, or a common circulating water plus tube heat exchanger, etc. The specific structure is the prior art, so it will not be described in detail. The temperature stabilizer is used to keep the temperature of the refrigerant in the first storage tank 610 and the second storage tank 620 stable within a preset range. Since the temperature of the refrigerator will affect the refrigeration work ability of the compressor 100, in order to control the variable, it is necessary to control the temperature of the refrigerant in the first storage tank 610 and the second storage tank 620 within a preset range. The accuracy of the detection result is effectively improved.

[0046] Reference Figures 1 to 5 As shown, it can be understood that a first refrigerant flow pipe 611 is vertically arranged on the upper end of the first storage tank 610, and one end of the first refrigerant flow pipe 611 away from the first storage tank 610 is connected to a hose 630 connected to the inlet of the compressor 100, and the first refrigerant flow pipe 611 is a metal hard pipe, which is convenient for installing temperature and pressure sensors.

A first shut-off valve 612 is arranged on the first refrigerant flow pipe 611, and the first refrigerant flow pipe 611 is a metal hard pipe, which is convenient for the first shut-off valve 612. A second shut-off valve 622 is arranged on the second refrigerant flow pipe 621. The second refrigerant flow pipe 621 is a metal hard pipe, which is convenient for the second shut-off valve 622. The temperature and pressure sensors may be disposed in the first storage tank 610 and the second storage tank 620 , and may also be disposed in the first refrigerant circulation pipe 611 and the second refrigerant circulation pipe 621 .

[0047] Reference Figures 1 to 5 As shown, it can be understood that a throttle 623 is provided on the second refrigerant flow pipe 621. In the air conditioning system, a throttle 623 is provided at the outlet of the compressor 100, and a throttle 623 is provided on the second refrigerant flow pipe 621 to simulate the actual working condition of the compressor 100, which is conducive to improving the accuracy of the detection result.

The second vacuum pump 800 is connected to the second refrigerant flow pipe 621, and the second vacuum pump 800 is connected to the second refrigerant flow pipe 621 through the second vacuum pipe. The second vacuum pipe is connected to the second refrigerant flow pipe 621 located above the second shut-off valve 622. The first vacuum pump 700 and the second vacuum pump 800 are used to extract the air in the compressor 100 and the hose 630 when the first shut-off valve 612 and the second shut-off valve 622 are closed. The air will not enter the first storage tank 610 and the second storage tank 620, so as to ensure the purity of the refrigerant in the first storage tank 610 and the second storage tank 620 and improve the life of the refrigerant cycle. The first vacuum pipe and the second vacuum pipe are both provided with a leak-proof valve.

[0049] Usage steps: Place the input end of the compressor 100 downward onto the electric chuck 410, and close the electric chuck 410 to clamp the input end of the compressor 100. Then, adjust the movement of the motor 320 and the horizontal cylinder 330 according to the position of the compressor 100, so that the two pressure blocks clamp the compressor 100 from the left and right ends. Then, connect the two hoses 630 to the inlet and outlet of the compressor 100, open the two anti-leakage valves, start the first vacuum pump 700 and the second vacuum pump 800, and shut down the first vacuum pump 700 and the second vacuum pump 800 after running for at least 5 minutes.
