Description

Technical Field

[0001] The present application relates to the technical field of brake caliper testing for new energy vehicles, and in particular to an exhaust and oil discharge testing device for automobile brake calipers. Background Art

[0002] The brake caliper of new energy vehicles is a key component in the vehicle's braking system, mainly used to clamp the brake disc to achieve the braking effect. According to different braking methods, calipers can be divided into single-piston, double-piston and multi-piston types, which are widely used in new energy cars, trucks and special-purpose vehicles. The design of the caliper must not only meet the different braking force requirements of the vehicle, but also take into account reliability and durability. As an important guarantee for vehicle driving safety, the brake caliper must have high strength, high precision and excellent fatigue resistance.

[0003] After the production of brake calipers for new energy vehicles is completed, in order to ensure that their performance meets the design requirements, they need to undergo a number of rigorous performance tests, including oil injection and exhaust tests, braking force tests, sealing tests, and durability tests. The oil injection and exhaust test is a key step in production testing, the purpose of which is to inject brake fluid into the caliper and exhaust the gas in it to ensure braking performance.

[0004] In the actual vehicle assembly process, the installation angle of the brake caliper is crucial to the precise positioning of the bleed screw hole. However, in the test environment of the laboratory, the caliper assembly is usually fixed on the test fixture, and the caliper may not reach the actual assembly angle during the test, which leads to the failure of smooth gas discharge, especially the presence of residual gas areas that are difficult to discharge, affecting the accuracy of the test data and in some cases may cause safety hazards, such as reduced braking performance or brake failure.

[0005] Even if the angle consistent with the actual vehicle assembly is taken into account, when adjusting the installation angle of the brake caliper, the operator needs to manually adjust the installation angle of the brake caliper and fix it. This link requires manual intervention, precise adjustment and repeated inspection, which not only increases the complexity of the operation, but also may cause incomplete gas emission due to errors in human operation, thereby affecting the accuracy of the test results. In addition, the existing oil injection and exhaust test process involves the linkage operation of multiple devices. In these processes, the operator also needs to monitor multiple parameters in real time and adjust the coordination between multiple devices to ensure the smooth operation of the test equipment. However, since multiple steps require manual coordination, this also greatly increases the difficulty of the test and the probability of error.

[0006] Therefore, the current oil injection and exhaust test process has great operational complexity, especially in the adjustment of the caliper installation angle and equipment coordination. Excessive reliance on manual intervention can easily lead to improper operation and low efficiency. In addition, due to the cumbersome angle adjustment and exhaust process, the test process is unstable and the reliability of the data is difficult to ensure. Summary of the invention

[0007] In order to improve the accuracy of the test results, the present application provides an automobile brake caliper exhaust and oil discharge test device.

[0008] The present application provides an automobile brake caliper exhaust and oil discharge test equipment, which adopts the following technical solution: An automobile brake caliper exhaust and oil discharge test equipment is used to test the brake caliper, comprising a test bench, the test bench is provided with a clamping tool for clamping the brake caliper, and the clamping tool can drive the brake caliper to rotate, and the clamping tool is provided with a nameplate identification mechanism for identifying the nameplate information on the brake caliper and an angle adjustment mechanism for adjusting the rotation angle of the brake caliper; The test bench is provided with an exhaust and oil discharge testing mechanism for testing the brake caliper and a cleaning mechanism for cleaning the inner cavity of the brake caliper after the test. The test bench is also provided with a control panel. The nameplate recognition mechanism, the angle adjustment mechanism, the exhaust and oil discharge testing mechanism and the cleaning mechanism are all electrically connected to the control panel.

[0009] By adopting the above technical scheme, when it is necessary to test the brake caliper, the brake caliper is installed on the clamping fixture, and the control panel is operated so that the control panel controls the nameplate identification mechanism to first identify the nameplate on the brake caliper, thereby identifying the brand, model, batch and other information of the brake caliper to be tested, and then the angle adjustment mechanism drives the brake caliper to rotate to the actual loading angle. At this time, the exhaust and oil discharge test mechanism performs oil filling, exhaust, pressurization and other tests on the inside of the brake caliper. After the test is completed, the cleaning mechanism automatically cleans the inside of the brake caliper. Since the entire process does not require too much manual participation, the errors and improper operations that may be caused by manual participation are greatly reduced, and the efficiency and accuracy of the test are greatly improved.

[0010] Optionally, the clamping fixture includes a fixed seat, a rotating shaft and a caliper assembly fixed plate, the fixed seat is fixed to the test bench, the rotating shaft is partially rotatably inserted in the fixed seat, the caliper assembly fixed plate is fixedly installed on the portion of the rotating shaft extending from the fixed seat, and the brake caliper is detachably fixedly installed on the caliper assembly fixed plate; The brake caliper is provided with a liquid inlet hole and a bleed screw hole, and the fixing seat is also provided with a driving mechanism for driving the rotating shaft to rotate. The driving mechanism is electrically connected to the control panel, and the driving mechanism can drive the bleed screw hole on the brake caliper to rotate to a vertical upward position.

[0011] By adopting the above technical solution, when the brake caliper needs to be rotated to the actual loading angle, the driving mechanism is controlled by the control panel, and the driving mechanism controls the rotation of the rotating shaft so that the brake caliper can be rotated to the actual loading angle. At this time, the bleed screw hole on the brake caliper is rotated to a vertical upward position, ensuring that the gas in the exhaust process can be discharged smoothly and avoiding gas residue in the test. At the same time, the design of the caliper assembly fixing plate facilitates the disassembly and installation of the caliper, so that different models of calipers can be easily adapted to the test equipment, thereby improving the versatility of the equipment.

[0012] Optionally, the driving mechanism includes a driving member, a driving bevel gear and a driven bevel gear, the driving member is mounted on the fixed seat and electrically connected to the control panel, the driving bevel gear is coaxially fixed on the output shaft of the driving member, the driven bevel gear is coaxially fixed on the rotating shaft, and the driving bevel gear and the driven bevel gear are meshed.

[0013] By adopting the above technical solution, when the driving part is working, the transmission of the active bevel gear and the driven bevel gear drives the rotation of the rotating shaft, so that the installation angle of the brake caliper is rotated to an angle consistent with the actual loading angle. Through the efficient automatic caliper angle adjustment method, accurate angle adjustment can be achieved through the electronic control system. The drive system ensures accurate control of the rotation angle through the gear transmission mechanism, and can automatically adjust the angle according to the instructions on the control panel, avoiding the error of manual adjustment and improving the accuracy and efficiency of the test process. The combination of the electronic control of the drive mechanism and the control panel makes the operation easier and more stable.

[0014] Optionally, the nameplate recognition mechanism includes a first mounting rod and an image recognition sensor, an arc-shaped avoidance groove is opened at the end of the fixed seat, one end of the first mounting rod passes through the avoidance groove and is fixedly connected to the end of the rotating shaft, the image recognition sensor is arranged at the other end of the first mounting rod, located at the nameplate position facing the brake caliper, and the image recognition sensor is electrically connected to the control panel.

[0015] By adopting the above technical solution, the image sensor will detect the nameplate on the brake caliper and automatically record the brand, model, batch and other information of the brake caliper to be detected. After confirmation, the driver will drive the rotating shaft to rotate. During the rotation, the angle adjustment mechanism will detect the rotation angle. When it rotates to the corresponding angle, the driver stops and rotates the brake caliper to the actual assembly angle of the vehicle. In this process, the brake caliper can be automatically identified and relevant information can be tracked, avoiding omissions or errors caused by manual identification or erroneous operations. The image recognition sensor can accurately capture the nameplate information, further improving the level of intelligence in the test process. This design can automatically record the brand, batch and other information of each caliper, ensuring the traceability of the entire test process, which is helpful for quality control and troubleshooting.

[0016] Optionally, the angle adjustment mechanism includes a second mounting rod, a laser emitter and a receiver, a plurality of avoidance slots are opened at the end of the fixed seat, one end of the second mounting rod passes through the corresponding avoidance slots and is fixedly connected to the end of the rotating shaft, the laser emitter is fixedly mounted on the other end of the second mounting rod, the receiver is fixedly connected to the fixed seat, and the receiver is composed of a plurality of sensor arrays in an arc shape, the laser emitter and the receiver are both electrically connected to the control panel, and when the rotating shaft rotates, the emitting end of the laser emitter can move along the arc direction of the receiver with a surface facing the receiver.

[0017] By adopting the above technical solution, during the rotation of the rotating shaft, the second mounting rod will drive the laser transmitter to rotate, and the laser emitted by the laser transmitter can be received by the receiver in real time, so as to determine the rotation angle of the brake caliper. Accurate rotation angle detection is achieved through the cooperation of the laser transmitter and the receiver. The emitted light of the laser transmitter can accurately quantify the rotation angle of the brake caliper by aligning it with the receiver. The receiver is designed in an arc shape consisting of multiple sensor arrays, which can capture laser signals over a wide range, making the entire angle adjustment process more flexible and stable. This structure not only improves the accuracy of angle adjustment, but also makes the adjustment process more automated, reducing the error caused by manual adjustment.

[0018] Optionally, the exhaust and oil discharge test mechanism includes a liquid storage tank, an oil filling pump, a pressure pump, a first switching valve, an oil delivery pipe, an oil delivery connecting pipe, an oil discharge connecting pipe, an oil discharge pipe and an ultrasonic bubble sensor, the inner cavity of the liquid storage tank is equipped with brake fluid, and both ends of the oil filling pump and the pressure pump are connected to the liquid storage tank and the first switching valve respectively through the oil delivery pipe; The oil delivery connecting pipe and the oil drain connecting pipe are both installed on the caliper assembly fixing plate, one end of the oil delivery connecting pipe is communicated with the first switching valve through the oil delivery pipe, and the other end can be communicated with the liquid inlet hole of the brake caliper installed on the caliper assembly fixing plate, one end of the oil drain connecting pipe is communicated with the oil drain pipe, and the other end can be communicated with the bleed screw hole of the brake caliper installed on the caliper assembly fixing plate, and the ultrasonic bubble sensor is installed on the oil drain pipe for detecting bubbles in the brake fluid passing through the oil drain pipe; The oil injection pump, the pressure pump, the first switching valve, and the ultrasonic bubble sensor are all electrically connected to the control panel.

[0019] By adopting the above technical solution, when the brake caliper rotates to the actual loading angle, the control panel automatically controls the oil filling pump to start, and the oil filling pump transports the brake fluid in the reservoir to the first switching valve through the oil delivery pipe. At this time, the first switching valve is connected to the oil filling pump, and the brake fluid enters the inner cavity of the brake caliper through the oil inlet hole after passing through the oil delivery connecting pipe. At this time, the air in the brake caliper will be discharged from the bleed screw hole. When the inner cavity of the brake caliper is full of brake fluid, the brake fluid will be discharged from the oil drain pipe after passing through the oil drain connecting pipe. During the discharge process, the ultrasonic bubble sensor will detect the bubbles in the brake fluid in the oil drain pipe. When no bubbles are detected, it means that the air in the inner cavity of the brake caliper has been exhausted.

[0020] Then, the first switching valve automatically switches to connect the booster pump to the first switching valve. At this time, the booster pump works to pressurize the brake fluid in the reservoir and pass it into the brake caliper through the oil pipe and the oil connecting pipe, thereby creating pressure in the brake caliper to simulate the working pressure that the brake caliper is subjected to during actual use. This pressure is usually set according to the needs of the brake caliper when working in an actual vehicle. By simulating the actual working environment, the booster pump ensures that the brake caliper can operate normally during the test, thereby verifying its sealing, exhaust performance and other key performance.

[0021] Optionally, both ends of the oil delivery connecting pipe and the oil discharge connecting pipe are respectively provided with a rotary sealing joint and a quick-connect joint, and the rotary sealing joint is used for rotary sealing connection between the oil delivery connecting pipe and the oil delivery pipe, or for rotary sealing connection between the oil discharge connecting pipe and the oil discharge pipe; The quick-connect joint can be detachably mounted on the ends of the oil delivery connecting pipe and the oil discharge connecting pipe, and the quick-connect joint is provided with a plurality of different models and sizes corresponding to different models of brake calipers.

[0022] By adopting the above technical solution, when the rotating shaft drives the caliper assembly fixing plate to rotate, the rotating sealing joint can reduce the impact of the oil connection pipe on the oil pipe when it rotates, so that the oil connection pipe can be connected to the oil pipe in rotation. The detachable quick-connect joint allows different types of brake calipers to be quickly connected and disassembled, improving the flexibility and adaptability of the equipment, especially during the test process, different caliper models can be quickly switched, shortening the working time and improving production efficiency.

[0023] Optionally, a gas-liquid separator and a vacuum pump are provided on the oil drain pipe, and both the gas-liquid separator and the vacuum pump are electrically connected to the control panel. The end of the oil drain pipe is connected to the inlet of the gas-liquid separator, and the gas outlet of the gas-liquid separator is connected to the suction port of the vacuum pump. A waste liquid collection tank is also provided on the test bench, and the liquid outlet of the gas-liquid separator is connected to the waste liquid collection tank.

[0024] By adopting the above technical solution, the setting of gas-liquid separator and vacuum pump solves the problem of gas and liquid mixing during oil discharge. The gas-liquid separator can effectively separate liquid and gas, ensure that bubbles are effectively removed, and prevent gas from entering the oil discharge pipe, thereby improving the reliability of test data. The role of the vacuum pump is to further extract gas after gas-liquid separation, reduce gas residue, and ensure that the liquid in the oil discharge pipe reaches the expected purity to prevent interference from bubbles.

[0025] Optionally, a connecting pipe is provided between the waste liquid collection tank and the liquid storage tank, the connecting pipe is provided with a filter for filtering impurities in the brake fluid, and the minimum liquid level in the waste liquid collection tank is higher than the height of the connecting point between the liquid storage tank and the connecting pipe.

[0026] By adopting the above technical solution, the connecting pipe between the waste liquid collection tank and the liquid storage tank and the filter design ensures the effective recovery of waste liquid and filters the impurities therein, preventing impurities from entering the liquid storage tank and contaminating the brake fluid. The liquid level design in the waste liquid collection tank ensures the smooth flow of liquid in the system and effectively prevents waste liquid from entering the liquid storage tank, further ensuring the quality of the liquid during the test.

[0027] Optionally, the cleaning mechanism includes a cleaning liquid storage tank, a liquid pump, a liquid injection pipe, a second switching valve and a cleaning liquid collection tank, the liquid pump is electrically connected to the control panel, and the liquid inlet and liquid outlet of the liquid pump are respectively connected to the cleaning liquid storage tank and the first switching valve through the liquid injection pipe; The second switching valve is arranged between the liquid outlet of the gas-liquid separator and the waste liquid collection tank and is connected to the two. The cleaning liquid collection tank is connected to the second switching valve, and the second switching valve is electrically connected to the control panel. When the second switching valve is switched, the liquid outlet of the gas-liquid separator is connected to the waste liquid collection tank or the cleaning liquid collection tank.

[0028] By adopting the above technical solution, the cleaning mechanism can effectively clean the test equipment after completing the exhaust and oil discharge test through the configuration of the cleaning liquid storage tank, the liquid pump and the cleaning liquid collection tank. The use of cleaning liquid can effectively remove residual liquid and impurities in the equipment, avoid cross contamination between different tests, and ensure the cleanliness of the equipment and the accuracy of the next use. At the same time, the setting of the second switching valve allows the cleaning liquid to flexibly flow into the cleaning liquid collection tank or the waste liquid collection tank, avoiding unnecessary waste of liquid and improving the resource utilization efficiency of the equipment.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. The whole process does not require too much operator involvement. It is only necessary to connect the corresponding pipes with the liquid inlet and the bleed screw holes on the brake caliper before the test begins. This process greatly reduces the stages of manual intervention, manual adjustment and manual inspection, and greatly reduces the complexity of the operation. Since there is no operator involvement and the whole process is fully automatic, it greatly reduces possible misoperations and errors during the operation, and greatly improves the accuracy of the test results; 2. When the brake caliper needs to be rotated to the actual loading angle, the driving mechanism is controlled by the control panel, and the driving mechanism controls the rotation of the rotating shaft to rotate the brake caliper to the actual loading angle. At this time, the bleed screw hole on the brake caliper is rotated to a vertical upward position to ensure that the gas in the exhaust process can be discharged smoothly and avoid gas residue in the test; 3. The image sensor will detect the nameplate on the brake caliper and automatically record the brand, model, batch and other information of the brake caliper to be detected. After confirmation, the driver will drive the rotating shaft to rotate. During the rotation process, the angle adjustment mechanism will detect the rotation angle. When it rotates to the corresponding angle, the driver stops, so that the brake caliper rotates to the actual assembly angle of the vehicle. During this process, the brake caliper can be automatically identified and relevant information can be tracked, avoiding omissions or errors caused by manual identification or incorrect operations. The image recognition sensor can accurately capture the nameplate information, further improving the intelligence level of the test process. This design can automatically record the brand, batch and other information of each caliper, ensuring the traceability of the entire test process, which is helpful for quality control and troubleshooting. 4. During the rotation of the rotating shaft, the second mounting rod will drive the laser transmitter to rotate, and the laser emitted by the laser transmitter can be received by the receiver in real time, so as to determine the rotation angle of the brake caliper. Through the cooperation of the laser transmitter and the receiver, accurate rotation angle detection is achieved. The emitted light of the laser transmitter can be aligned with the receiver to accurately quantify the rotation angle of the brake caliper; The receiver is designed in an arc shape consisting of multiple sensor arrays, which can capture laser signals over a large range, making the entire angle adjustment process more flexible and stable. This structure not only improves the accuracy of angle adjustment, but also makes the adjustment process more automated, reducing the errors caused by manual adjustment.

[0033] The following is combined with Figure 1-5 , further details of this application are given.

[0034] The embodiment of the present application discloses an automobile brake caliper exhaust and oil discharge test device.

[0035] Reference Figure 1 and Figure 2 , an automobile brake caliper exhaust and oil discharge test equipment, used for testing a brake caliper 231, comprises a test bench 1, on which a clamping fixture 2 for clamping the brake caliper 231 is provided, and the clamping fixture 2 can drive the brake caliper 231 to rotate, and the clamping fixture 2 is provided with a nameplate identification mechanism 4 for identifying the nameplate information on the brake caliper 231 and an angle adjustment mechanism 5 for adjusting the rotation angle of the brake caliper 231.

[0036] The test bench 1 is provided with an exhaust and oil discharge testing mechanism 6 for testing the brake caliper 231 and a cleaning mechanism 7 for cleaning the inner cavity of the brake caliper 231 after the test. The test bench 1 is also provided with a control panel 11. The nameplate identification mechanism 4, the angle adjustment mechanism 5, the exhaust and oil discharge testing mechanism 6 and the cleaning mechanism 7 are all electrically connected to the control panel 11.

[0037] The control panel 11 is electrically connected to all electrical components, and a fully automatic test program is pre-set in the program of the control panel 11. When the brake caliper 231 needs to be tested, the brake caliper 231 is fixedly installed on the clamping fixture 2, and the pipelines involved in the exhaust and oil discharge test mechanism 6, the cleaning mechanism 7, etc. are connected to the brake caliper 231, and then the program is started. The control panel 11 will automatically realize the entire experimental process.

[0038] The nameplate identification mechanism 4 first identifies the nameplate information on the brake caliper 231, records the actual loading angle of the brake caliper 231 to be tested, and then the driving mechanism 3 drives the brake caliper 231 to rotate. During the rotation process, the angle adjustment mechanism 5 will detect the rotation angle of the brake caliper 231. When it rotates to the actual loading angle, the driving mechanism 3 stops rotating and fixes the brake caliper 231 at the actual loading angle.

[0039] Then, the exhaust and oil discharge test mechanism 6 automatically performs the oil filling, exhaust and pressurization test. After the test is completed, the cleaning mechanism 7 automatically cleans the inner cavity of the brake caliper 231 to complete the entire experimental process.

[0040] The following is a detailed description of all the structures involved above: Specifically, refer to Figure 2 and Figure 3 The clamping fixture 2 includes a fixed seat 21, a rotating shaft 22 and a caliper assembly fixed plate 23. The fixed seat 21 is fixed on the test bench 1. The rotating shaft 22 is partially rotatably inserted in the fixed seat 21. The caliper assembly fixed plate 23 is fixedly installed on the portion of the rotating shaft 22 extending out of the fixed seat 21. The brake caliper 231 is detachably fixedly installed on the caliper assembly fixed plate 23.

[0041] The brake caliper 231 is provided with a liquid inlet hole 2311 and a bleed screw hole 2312. The fixed seat 21 is also provided with a driving mechanism 3 for driving the rotating shaft 22 to rotate. The driving mechanism 3 is electrically connected to the control panel 11. The driving mechanism 3 can drive the bleed screw hole 2312 on the brake caliper 231 to rotate to a vertical upward position.

[0042] Reference Figure 2 and Figure 3 The driving mechanism 3 includes a driving member 31, a driving bevel gear 32 and a driven bevel gear 33. The driving member 31 can be a reduction motor, a stepping motor, etc. In the present embodiment, the driving member 31 is a reduction motor, which is mounted on the fixing seat 21 and electrically connected to the control panel 11. The driving bevel gear 32 is coaxially fixed on the output shaft of the reduction motor, and the driven bevel gear 33 is coaxially fixed on the rotating shaft 22, and the driving bevel gear 32 and the driven bevel gear 33 are meshed.

[0043] When the reduction motor is working, the transmission of the active bevel gear 32 and the driven bevel gear 33 drives the rotation of the rotating shaft 22, so that the installation angle of the brake caliper 231 is rotated to an angle consistent with the actual loading angle. Through the efficient automatic caliper angle adjustment method, accurate angle adjustment can be achieved through the electronic control system.

[0044] The drive system ensures accurate control of the rotation angle through the gear transmission mechanism, and can automatically adjust the angle according to the instructions on the control panel 11, avoiding the error of manual adjustment and improving the accuracy and efficiency of the test process. The combination of the electric control of the drive mechanism 3 and the control panel 11 makes the operation easier and more stable.

[0045] Reference Figure 2 and Figure 3 The nameplate recognition mechanism 4 includes a first mounting rod 41 and an image recognition sensor 42. An arc-shaped avoidance groove 211 is opened at the end of the fixed seat 21. One end of the first mounting rod 41 passes through the avoidance groove 211 and is fixedly connected to the end of the rotating shaft 22. The image recognition sensor 42 is arranged at the other end of the first mounting rod 41, located at the nameplate position facing the brake caliper 231, and the image recognition sensor 42 is electrically connected to the control panel 11.

[0046] The image sensor will detect the nameplate on the brake caliper 231 and automatically record the brand, model, batch and other information of the brake caliper 231 to be detected. After confirmation, the reduction motor drives the rotating shaft 22 to rotate. During the rotation, the angle adjustment mechanism 5 will detect the rotation angle. When it rotates to the corresponding angle, the reduction motor stops, allowing the brake caliper 231 to rotate to the actual assembly angle for loading.

[0047] During this process, the brake caliper 231 can be automatically identified and relevant information can be tracked, avoiding omissions or errors caused by manual identification or erroneous operations. The image recognition sensor 42 can accurately capture the nameplate information, further improving the level of intelligence in the test process. This design can automatically record the brand, batch and other information of each brake caliper 231, ensuring the traceability of the entire test process, and facilitating quality control and troubleshooting.

[0048] Since the colors of different models and brands of brake calipers 231 may be different, the colors of their nameplates may also be different, and the image recognition sensor 42 is greatly affected by external light sources, in order to enable the image recognition sensor 42 to have a good recognition effect in environments with different external light intensities and nameplates of different colors, a light shielding adjustment mechanism 8 is provided between the image recognition sensor 42 and the nameplate of the brake caliper 231.

[0049] Reference Figure 3 and Figure 4 The light-shielding degree adjustment mechanism 8 includes a light-shielding tube 81, a light-shielding sheet 82, a servo motor 83, a point light source 84, and a light sensor 85. The light-shielding tube 81 is hollow, and a reflective coating is coated on the inner wall. The light-shielding tube 81 is installed at the end of the image recognition sensor 42, and the recognition end of the image recognition sensor 42 is directly opposite to the opening end of the light-shielding tube 81. The shading sheet 82 is rotatably installed in the shading tube 81, and the initial surface of the shading sheet 82 is perpendicular to the length direction of the shading tube 81. The transmittance at this position is the largest. In other embodiments, if the shading sheet 82 needs to have more transmittance adjustment, the shading sheet 82 can be set to have different thicknesses at both ends. In this case, a wider range of transmittance adjustment can be achieved.

[0050] The servo motor 83 is installed on the top of the light shielding tube 81, and the output shaft is connected to the light shielding sheet 82. When the servo motor 83 rotates, it can drive the light shielding sheet 82 to rotate a certain angle, so that the intensity of light passing through the light shielding sheet 82 and reaching the image recognition sensor 42 can be changed; There are multiple point light sources 84 evenly and spaced apart. The multiple point light sources 84 are spaced apart at the end of the light shielding tube 81 away from the image recognition sensor 42 . There are two light sensors 85 symmetrically disposed on the inner wall of the light shielding tube 81 .

[0051] When the nameplate of the brake caliper 231 is in an environment with too strong light, the nameplate may glow, making it difficult for the image recognition sensor 42 to accurately identify the information on the nameplate. At this time, the light sensor 85 detects the light intensity, and the servo motor 83 drives the shading plate 82 to rotate the corresponding angle, so that the information on the nameplate can be accurately identified by the image recognition sensor 42.

[0052] When the nameplate of the brake caliper 231 is in a low-light environment, multiple point light sources 84 evenly illuminate the surface of the nameplate, so that the information on the surface of the nameplate can be accurately recognized by the image recognition sensor 42, making the adjustment angle of the brake caliper 231 more accurate.

[0053] Specifically, refer to Figure 2 and Figure 3The angle adjustment mechanism 5 includes a second mounting rod 51, a laser emitter 52 and a receiver 53. A plurality of avoidance slots 211 are provided at the end of the fixed seat 21. One end of the second mounting rod 51 passes through the corresponding avoidance slots 211 and is fixedly connected to the end of the rotating shaft 22. The laser emitter 52 is fixedly mounted on the other end of the second mounting rod 51. The receiver 53 is fixedly connected to the fixed seat 21, and the receiver 53 is composed of a plurality of sensor arrays in an arc shape. The laser emitter 52 and the receiver 53 are both electrically connected to the control panel 11. When the rotating shaft 22 rotates, the emitting end of the laser emitter 52 can move along the arc direction of the receiver 53 with the surface facing the receiver 53.

[0054] During the rotation of the rotating shaft 22, the second mounting rod 51 drives the laser emitter 52 to rotate, and the laser emitted by the laser emitter 52 can be received by the receiver 53 in real time, thereby determining the rotation angle of the brake caliper 231. When the brake caliper 231 rotates, the image recognition sensor 42 starts to detect the nameplate information on the brake caliper 231, and through the cooperation of the laser emitter 52 and the receiver 53, accurate angle adjustment is achieved.

[0055] The emitted light of the laser emitter 52 can accurately quantify the rotation angle of the brake caliper 231 by aligning with the receiver 53. The receiver 53 is designed in an arc shape consisting of multiple sensor arrays, which can capture laser signals over a wide range, making the entire angle adjustment process more flexible and stable. This structure not only improves the accuracy of angle adjustment, but also makes the adjustment process more automated, reducing the error caused by manual adjustment.

[0056] After the adjustment of the actual mounting angle of the brake caliper 231 is completed, an exhaust and oil discharge test will be performed. Figure 1 , Figure 2 and Figure 4 The exhaust and oil discharge test mechanism 6 includes a liquid storage tank 61, an oil filling pump 62, a pressure pump 63, a first switching valve 64, an oil delivery pipe 65, an oil delivery connecting pipe 66, an oil discharge connecting pipe 67, an oil discharge pipe 68 and an ultrasonic bubble sensor 69. Brake fluid is installed in the inner cavity of the liquid storage tank 61, and both ends of the oil filling pump 62 and the pressure pump 63 are connected to the liquid storage tank 61 and the first switching valve 64 respectively through the oil delivery pipe 65.

[0057] The oil supply connecting pipe 66 and the oil drain connecting pipe 67 are both installed on the caliper assembly fixing plate 23. One end of the oil supply connecting pipe 66 is connected to the first switching valve 64 through the oil supply pipe 65, and the other end can be connected to the liquid inlet hole 2311 of the brake caliper 231 installed on the caliper assembly fixing plate 23. One end of the oil drain connecting pipe 67 is connected to the oil drain pipe 68, and the other end can be connected to the air bleed screw hole 2312 of the brake caliper 231 installed on the caliper assembly fixing plate 23. The ultrasonic bubble sensor 69 is installed on the oil drain pipe 68 for detecting bubbles in the brake fluid passing through the oil drain pipe 68.

[0058] The oil filling pump 62 , the pressure pump 63 , the first switching valve 64 , and the ultrasonic bubble sensor 69 are all electrically connected to the control panel 11 .

[0059] When the brake caliper 231 rotates to the actual loading angle, the control panel 11 automatically controls the oil filling pump 62 to start, and the oil filling pump 62 transports the brake fluid in the reservoir 61 to the first switching valve 64 through the oil pipe 65. At this time, the first switching valve 64 is connected to the oil filling pump 62, and the brake fluid enters the inner cavity of the brake caliper 231 through the oil inlet hole 2311 after passing through the oil connecting pipe 66. At this time, the air in the brake caliper 231 will be discharged from the bleed screw hole 2312.

[0060] When the inner cavity of the brake caliper 231 is filled with brake fluid, the brake fluid will be discharged from the oil drain pipe 68 after passing through the oil drain connecting pipe 67. During the discharge process, the ultrasonic bubble sensor 69 will detect the bubbles in the brake fluid in the oil drain pipe 68. When no bubbles are detected, it means that the air in the inner cavity of the brake caliper 231 has been discharged.

[0061] Then, the first switching valve 64 automatically switches to connect the pressure pump 63 to the first switching valve 64. At this time, the pressure pump 63 works. The pressure pump 63 pressurizes the brake fluid in the fluid storage tank 61 and passes it into the brake caliper 231 through the oil pipe 65 and the oil connecting pipe 66, thereby creating pressure in the brake caliper 231 to simulate the working pressure that the brake caliper 231 is subjected to during actual use. This pressure is usually set according to the requirements of the brake caliper 231 when working in an actual vehicle.

[0062] By simulating the actual working environment, the booster pump 63 ensures that the brake caliper 231 can operate normally during the test, thereby verifying its sealing, exhaust performance and other key performances.

[0063] Further, see Figure 1 and Figure 3The two ends of the oil delivery connection pipe 66 and the oil discharge connection pipe 67 are respectively provided with a rotary seal joint 671 and a quick connector 672. The rotary seal joint 671 is used for rotary seal connection of the oil delivery connection pipe 66 and the oil delivery pipe 65, or for rotary seal connection of the oil discharge connection pipe 67 and the oil discharge pipe 68. The quick connector 672 can be detachably installed at the ends of the oil delivery connection pipe 66 and the oil discharge connection pipe 67, and the quick connector 672 is provided with a variety of different models and sizes corresponding to different models of brake calipers 231.

[0064] When the rotating shaft 22 drives the caliper assembly fixing plate 23 to rotate, the rotating sealing joint 671 can reduce the impact of the oil connection pipe 66 on the oil pipe 65 when rotating, so that the oil connection pipe 66 can be rotatably connected with the oil pipe 65. The detachable quick-connect joint 672 enables different types of brake calipers 231 to be quickly connected and disassembled, improving the flexibility and adaptability of the equipment, especially in the test process, different types of brake calipers 231 can be quickly switched, shortening the working time and improving production efficiency.

[0065] Reference Figure 1 and 5 A gas-liquid separator 681 and a vacuum pump 682 are provided on the oil drain pipe 68, and both the gas-liquid separator 681 and the vacuum pump 682 are electrically connected to the control panel 11. The end of the oil drain pipe 68 is connected to the inlet of the gas-liquid separator 681, and the gas outlet of the gas-liquid separator 681 is connected to the suction port of the vacuum pump 682. A waste liquid collection tank 12 is also provided on the test bench 1, and the liquid outlet of the gas-liquid separator 681 is connected to the waste liquid collection tank 12.

[0066] The setting of the gas-liquid separator 681 and the vacuum pump 682 solves the problem of gas and liquid mixing during the oil discharge process. The gas-liquid separator 681 can effectively separate liquid and gas, ensure that bubbles are effectively removed, and prevent gas from entering the oil discharge pipe 68, thereby improving the reliability of the test data. The role of the vacuum pump 682 is to further extract gas after gas-liquid separation, reduce gas residue, and ensure that the liquid in the oil discharge pipe 68 reaches the expected purity to prevent interference from bubbles.

[0067] Reference Figure 1 and Figure 5A connecting pipe 13 is provided between the waste liquid collection tank 12 and the liquid storage tank 61, and a filter 14 is provided on the connecting pipe 13 for filtering impurities in the brake fluid, and the minimum liquid level in the waste liquid collection tank 12 is higher than the height of the connection point between the liquid storage tank 61 and the connecting pipe 13. The design of the connecting pipe 13 and the filter 14 between the waste liquid collection tank 12 and the liquid storage tank 61 ensures the effective recovery of the waste liquid, and filters the impurities therein, preventing the impurities from entering the liquid storage tank 61 and contaminating the brake fluid. The design of the liquid level in the waste liquid collection tank 12 ensures the smooth flow of the liquid in the system, and effectively prevents the waste liquid from entering the liquid storage tank 61, further ensuring the quality of the liquid during the test.

[0068] Reference Figure 1 and Figure 5 The cleaning mechanism 7 includes a cleaning liquid storage tank 71, a liquid pump 72, a liquid injection pipe 73, a second switching valve 74 and a cleaning liquid collection tank 75. The liquid pump 72 is electrically connected to the control panel 11, and the liquid inlet end and the liquid outlet end of the liquid pump 72 are respectively connected to the cleaning liquid storage tank 71 and the first switching valve 64 through the liquid injection pipe 73; The second switching valve 74 is arranged between the liquid outlet of the gas-liquid separator 681 and the waste liquid collection tank 12 and is connected to the two. The cleaning liquid collection tank 75 is connected to the second switching valve 74. The second switching valve 74 is electrically connected to the control panel 11. When the second switching valve 74 is switched, the liquid outlet of the gas-liquid separator 681 is connected to the waste liquid collection tank 12 or the cleaning liquid collection tank 75.

[0069] The cleaning mechanism 7 is configured with a cleaning liquid storage tank 71, a liquid pump 72 and a cleaning liquid collection tank 75, so that the test equipment can be effectively cleaned after completing the exhaust and oil discharge test. The use of cleaning liquid can effectively remove residual liquid and impurities in the equipment, avoid cross contamination between different tests, and ensure the cleanliness of the equipment and the accuracy of the next use. At the same time, the setting of the second switching valve 74 allows the cleaning liquid to flexibly flow into the cleaning liquid collection tank 75 or the waste liquid collection tank 12, avoiding unnecessary waste of liquid and improving the resource utilization efficiency of the equipment.

[0070] The implementation principle of an automobile brake caliper exhaust and oil discharge test equipment in an embodiment of the present application is as follows: when the brake caliper 231 needs to be tested, the brake caliper 231 is installed on the clamping fixture 2, and the control panel 11 is operated so that the control panel 11 controls the nameplate recognition mechanism 4 to first identify the nameplate on the brake caliper 231, thereby identifying the brand, model, batch and other information of the brake caliper 231 to be tested, and then the angle adjustment mechanism 5 drives the brake caliper 231 to rotate to the actual loading angle. At this time, the exhaust and oil discharge test mechanism 6 performs oil filling, exhaust, pressurization and other tests on the inside of the brake caliper 231. After the test is completed, the cleaning mechanism 7 automatically cleans the inside of the brake caliper 231. Since the entire process does not require too much manual participation, the errors and improper operations that may be caused by manual participation are greatly reduced, and the efficiency and accuracy of the test are greatly improved.

[0071] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
