Description

Technical Field

[0001] This utility model relates to the field of air conditioner testing technology, and in particular to a testing device for air conditioner repair. Background Technology

[0002] As the core component of the air conditioning refrigeration system, the performance of the air conditioning compressor directly determines the operating efficiency and service life of the air conditioner. During the air conditioning repair process, it is necessary to accurately test key indicators such as the airtightness, high and low pressure conditions, and operational stability of the air conditioning compressor in order to determine the cause of the fault and formulate a repair plan. The professional equipment used for this testing scenario is an important tool for achieving efficient repair.

[0003] However, existing testing equipment has the following shortcomings in practical use:

[0004] On the one hand, most equipment only has a single air conditioner compressor with a clear work station. During testing, the entire process of fixing, wiring, and testing an air conditioner compressor must be completed before the next one can be replaced, resulting in low testing efficiency. This is especially true in scenarios with a large volume of repairs, making it difficult to meet the needs of batch testing.

[0005] On the other hand, the air conditioner compressor is often fixed by rigid clamping, which lacks a buffer structure. This can easily damage the air conditioner compressor casing due to improper clamping force control. At the same time, there is no precise positioning structure during fixing, which may lead to misalignment between the air conditioner compressor and the testing pipeline, affecting the accuracy of the test data. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a testing device for air conditioner repair, which overcomes the shortcomings of the prior art and effectively solves the problems of low single-station testing efficiency and easy damage to the fixed air conditioner compressor due to lack of buffer.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A testing device for air conditioner repair includes an operating table. A stepper motor is fixedly connected to the bottom outer wall of the operating table by screws, and the output shaft of the stepper motor is fixedly connected to a docking frame by a coupling. An air conditioner compressor placement platform is welded to the outer walls of both ends of the docking frame. A support frame is welded to the top outer wall of the operating table, and a cylinder is fixedly connected to the top outer wall of the support frame by screws. A lower pressure plate is fixedly connected to the piston rod of the cylinder, and adjacent guide rods are arranged through the outer wall of the lower pressure plate. A clamping plate is welded to the bottom outer wall of the guide rod, and a buffer spring is fixedly connected between the clamping plate and the lower pressure plate.

[0009] Preferably, a control cabinet is fixedly connected to one side of the top outer wall of the control panel by screws, and a display screen is provided on the inclined surface of one side outer wall of the control cabinet, and an alarm is installed on the top outer wall of the control cabinet.

[0010] Preferably, an air conditioning compressor is placed on the outer wall of the top of one of the air conditioning compressor placement platforms, and adjacent high-voltage detection lines and low-voltage detection lines are connected between the air conditioning compressor and the control cabinet.

[0011] Preferably, the bottom outer wall of the operating table is fixedly connected to a detection box by screws, and one side outer wall of the detection box is fixedly connected to an adjacent first fixing pipe and a second fixing pipe.

[0012] Preferably, a suction pipe is fixedly connected between the first fixed pipe and the air conditioning compressor, and an exhaust pipe is fixedly connected between the second fixed pipe and the air conditioning compressor.

[0013] Preferably, solenoid valves and pressure gauges are fixedly connected to the outer walls of both the first and second fixed pipes, and the control cabinet is connected to the stepper motor, cylinder, detection box, solenoid valves and pressure gauges via signal lines.

[0014] Preferably, the top outer wall of the air conditioner compressor placement platform is provided with a positioning groove, and the size of the positioning groove is adapted to the size of the air conditioner compressor.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The testing equipment for air conditioner repair designed in this paper improves testing efficiency through a dual-station design. The stepper motor at the bottom of the operating table can drive the docking frame to rotate, allowing the air conditioner compressor placement platforms at both ends to alternately enter the testing station. While one air conditioner compressor is being tested, the placement and preliminary preparation of the air conditioner compressor to be tested can be completed on the other placement platform, which greatly shortens the equipment's idle time and solves the problem of low testing efficiency of traditional single-station equipment. It is especially suitable for batch repair scenarios.

[0017] 2. The testing equipment designed for air conditioner repair optimizes the fixing effect and testing accuracy of the air conditioner compressor. The positioning slot on the air conditioner compressor placement platform is adapted to the size of the air conditioner compressor, enabling quick and accurate positioning and ensuring accurate connection of the testing pipelines. At the same time, when the cylinder drives the lower pressure plate to descend, the clamping plate uses a buffer spring to elastically clamp the air conditioner compressor, avoiding damage to the outer shell caused by rigid clamping. This solves the defects of traditional fixing methods, such as inaccurate positioning and easy damage to the air conditioner compressor, and ensures the safety and data reliability of the testing process.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 Example 1: A testing device for air conditioner repair includes an operating table 1. A stepper motor 2 is fixedly connected to the bottom outer wall of the operating table 1 by screws, and the output shaft of the stepper motor 2 is fixedly connected to a docking frame 3 by a coupling. An air conditioner compressor placement platform 4 is welded to the outer walls of both ends of the docking frame 3. A positioning groove 22 is opened on the top outer wall of the air conditioner compressor placement platform 4, and the size of the positioning groove 22 is adapted to the size of the air conditioner compressor.

[0027] With the above solution, the stepper motor 2 serves as the power source, and the rotation of its output shaft can drive the docking frame 3 to rotate around the axis, thereby realizing the switching of the work positions of the two air conditioning compressor placement platforms 4; the positioning slot 22 can play a precise limiting role for the air conditioning compressor. When placing it, simply put the air conditioning compressor into the slot to ensure that its center is aligned with the center of the subsequent testing pipeline and clamping structure, without the need for repeated manual adjustments, thus improving the ease of operation.

[0028] In this embodiment, the dual-station design improves testing efficiency. The stepper motor 2 at the bottom of the operating table 1 can drive the docking frame 3 to rotate, allowing the air conditioner compressor placement tables 4 at both ends to alternately enter the testing station. While one air conditioner compressor is being tested, the placement and preliminary preparation of the air conditioner compressor to be tested can be completed on the other placement table, which greatly shortens the equipment idle time and solves the problem of low testing efficiency of traditional single-station equipment. It is especially suitable for batch repair scenarios.

[0029] In embodiment 2, a support frame 5 is welded to the top outer wall of the operating table 1, and a cylinder 6 is fixedly connected to the top outer wall of the support frame 5 by screws. The piston rod of the cylinder 6 is fixedly connected to a lower pressure plate 7, and adjacent guide rods 8 are arranged through the outer wall of the lower pressure plate 7. A clamping plate 9 is welded to the bottom outer wall of the guide rod 8, and a buffer spring 10 is fixedly connected between the clamping plate 9 and the lower pressure plate 7.

[0030] Through the above scheme, the support frame 5 provides stable installation support for the cylinder 6, ensuring that it will not shake during operation; the cylinder 6 drives the lower pressure plate 7 to move up and down through the extension and retraction of the piston rod, and the guide rod 8 can limit the movement direction of the clamping plate 9 to prevent it from shifting during clamping; the buffer spring 10 has elastic extension and retraction characteristics. When the clamping plate 9 contacts the air conditioner compressor, the buffer spring 10 will automatically adjust the compression amount according to the shape and hardness of the air conditioner compressor shell to achieve flexible clamping and prevent excessive pressure from damaging the equipment.

[0031] In this embodiment, the fixing effect and detection accuracy of the air conditioner compressor are optimized. The positioning slot 22 on the air conditioner compressor placement platform 4 is adapted to the size of the air conditioner compressor, which can quickly achieve accurate positioning and ensure accurate connection of the detection pipeline. At the same time, when the cylinder 6 drives the lower pressure plate 7 to descend, the clamping plate 9 uses the buffer spring 10 to elastically clamp the air conditioner compressor, avoiding damage to the outer shell caused by rigid clamping. This solves the defects of inaccurate positioning and easy damage to the air conditioner compressor in the traditional fixing method, and ensures the safety and data reliability of the detection process.

[0032] The control cabinet 11 is fixedly connected to one side of the top outer wall of the control console 1 by screws, and a display screen 12 is provided on the inclined surface of one side of the outer wall of the control cabinet 11. An alarm 23 is installed on the top outer wall of the control cabinet 11.

[0033] With the above solution, the control cabinet 11 is the control core of the equipment, which integrates control chips, circuit modules, etc., and can receive signals from various components and issue control commands. The tilted display screen 12 is ergonomically designed, making it convenient for operators to clearly view detection data, equipment operating status and other information while standing. When the detection data exceeds the normal range or the equipment malfunctions, the alarm 23 will issue an audible and visual alarm to promptly remind the operator to handle the situation.

[0034] An air conditioning compressor is placed on the top outer wall of one of the air conditioning compressor placement platforms 4, and high-voltage detection lines 13 and low-voltage detection lines 14 are connected adjacently between the air conditioning compressor and the control cabinet 11.

[0035] Through the above scheme, the high-voltage detection line 13 and the low-voltage detection line 14 are signal transmission channels connecting the air conditioner compressor and the control cabinet 11. They are used to collect key parameters such as pressure and voltage at the high-voltage and low-voltage ends of the air conditioner compressor during operation. The plug-in connection method facilitates quick plugging and unplugging. When replacing the air conditioner compressor, the wiring and disconnection operations can be completed efficiently, further improving the detection efficiency.

[0036] The bottom outer wall of the operating table 1 is fixedly connected to the detection box 15 by screws, and the outer wall of one side of the detection box 15 is fixedly connected to the adjacent first fixed pipe 16 and second fixed pipe 17. The first fixed pipe 16 and the air conditioner compressor are fixedly connected to the suction pipe 18, and the second fixed pipe 17 and the air conditioner compressor are fixedly connected to the exhaust pipe 19.

[0037] Through the above scheme, the test box 15 can integrate devices such as a vacuum pump and a gas delivery pump to simulate the actual operating conditions of the air conditioner compressor; the first fixed pipe 16 cooperates with the extraction pipe 18 to evacuate the air conditioner compressor or extract the internal gas for component detection; the second fixed pipe 17 and the exhaust pipe 19 are used to inject test gas into the air conditioner compressor or discharge internal gas to realize the detection of indicators such as the air conditioner compressor's sealing performance and ventilation performance.

[0038] Solenoid valves 20 and pressure gauges 21 are fixedly connected to the outer walls of the first fixed tube 16 and the second fixed tube 17, and the control cabinet 11 is connected to the stepper motor 2, cylinder 6, detection box 15, solenoid valves 20 and pressure gauges 21 through signal lines.

[0039] Through the above scheme, the solenoid valve 20 is used to control the opening and closing of the first fixed pipe 16 and the second fixed pipe 17. The operator can remotely control the valve opening and closing through the control cabinet 11 to realize the automation of the detection process. The pressure gauge 21 can monitor the pressure change in the pipe in real time and transmit the pressure data to the control cabinet 11 through the signal line, and finally display it on the display screen 12, so that the operator can keep track of the detection pressure status in real time. The signal connection between each component and the control cabinet 11 realizes the centralized control and data integration of the equipment, and improves the automation level and data accuracy of the detection process.

[0040] Working principle: First, the equipment is initialized by setting detection parameters, such as the detection pressure range and clamping force threshold, through the control cabinet 11. Then, the air conditioner compressor to be tested is placed into the positioning slot 22 of one of the air conditioner compressor placement platforms 4 to complete the initial positioning. The control cabinet 11 is then activated to start cylinder 6. The piston rod of cylinder 6 pushes the lower pressure plate 7 down, and the guide rod 8 guides the clamping plate 9 to contact the top of the air conditioner compressor. The buffer spring 10 is compressed and provides elastic clamping force to firmly fix the air conditioner compressor.

[0041] Next, connect the high-pressure detection line 13 and the low-pressure detection line 14 to the high and low pressure interfaces of the air conditioning compressor and the control cabinet 11, respectively. At the same time, connect the suction pipe 18 and the exhaust pipe 19 to the air conditioning compressor interface and the first fixed pipe 16 and the second fixed pipe 17, respectively. After the connection is completed, start the detection box 15 through the control cabinet 11 and open the corresponding solenoid valve 20. The detection box 15 evacuates or injects detection gas into the air conditioning compressor through the suction pipe 18. The exhaust pipe 19 cooperates to complete the gas circulation or discharge. The pressure gauge 21 monitors the pressure in the pipe in real time and transmits the data to the control cabinet 11. The high-pressure detection line 13 and the low-pressure detection line 14 collect the operating parameters of the air conditioning compressor. All data are displayed on the display screen 12.

[0042] If the test data is abnormal, alarm 23 will sound an alarm. After the current air conditioner compressor test is completed, stepper motor 2 is started, which drives docking frame 3 to rotate, turning the tested air conditioner compressor out of the test station. At the same time, another air conditioner compressor to be tested, prepared in advance on another placement table, is turned into the station. The above fixing, wiring, and testing process is repeated to achieve continuous and efficient testing. After all tests are completed, the equipment is turned off, all connecting pipelines are disconnected, and the air conditioner compressor can be removed.

[0043] 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.
