Description

Technical Field

[0001] This invention relates to the field of sealing ring testing equipment, and more specifically, to a sealing ring testing bench for clutch actuators. Background Technology

[0002] The sealing ring is a key component of the clutch actuator, and its durability directly affects the product's lifespan. After the sealing ring is manufactured, it is usually tested under normal pressure to ensure its quality. However, this test does not cover the special requirements of subsequent assembly products. The sealing ring has a frameless K-type structure, and the product includes two different sizes of sealing rings. It is necessary to test their sealing durability under high pressure gas simultaneously. However, existing sealing ring tests can only test a single size of sealing ring and cannot test two different sizes of sealing rings at the same time. Moreover, the test operation is relatively complicated, resulting in low testing efficiency and poor adaptability.

[0003] Based on the above, we provide a test bench for clutch actuator seals to quickly test the durability of seals of different sizes and specifications on the assembly products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a test bench for the sealing rings of clutch actuators, which can test the sealing rings under high-pressure gas and different operating frequencies, and can simultaneously test sealing rings of different specifications and sizes. The test operation is simple and can solve the technical problems existing in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a test bench for the sealing ring of a clutch actuator, the test bench comprising:

[0006] - The main frame of the platform consists of two parts: an upper frame and a lower frame;

[0007] - The cam linkage mechanism is fixedly installed on the platform at the bottom of the upper frame. The bottom of the cam linkage mechanism is connected to a servo motor that drives its axial swing to swing repeatedly. The servo motor is fixedly connected to the lower frame through a mounting bracket. The two ends of the cam linkage mechanism are respectively connected to a large sealing ring assembly fixture and a small sealing ring assembly fixture. Each assembly fixture can install three sealing rings of the same specification for testing.

[0008] - The electric control triplet is fixedly installed at the bottom left end of the lower frame. The air inlet of the electric control triplet is connected to the air source of the assembly line through the air inlet pipe. The two air outlet pipes of the electric control triplet are respectively connected to the large sealing ring assembly fixture and the small sealing ring assembly fixture through the air supply pipe to regulate the gas pressure inside the aforementioned two fixtures.

[0009] - The leak tester is fixedly installed on the left front side of the bottom of the lower frame. The detection interface of the leak tester is connected to the large sealing ring assembly fixture and the small sealing ring assembly fixture through a set of detection gas tubes, which are used to monitor the leakage of gas in the large sealing ring assembly fixture and the small sealing ring assembly fixture.

[0010] Preferably, the test bench also includes two sets of temperature sensors, one set of displacement sensors, and an industrial control computer;

[0011] Two sets of temperature sensors are used. One set of temperature sensors is fixedly installed inside the large sealing ring assembly fixture to monitor the temperature inside the cavity of the large sealing ring assembly fixture, while the other set of temperature sensors is fixedly installed inside the small sealing ring assembly fixture to monitor the temperature inside the cavity of the small sealing ring assembly fixture.

[0012] A set of displacement sensors are symmetrically fixed on the platforms on both sides of the cam linkage mechanism to detect the position of the connecting shaft of the cam linkage mechanism, so as to ensure that the cam linkage mechanism can operate stably.

[0013] The industrial control computer is fixedly installed on the right front side of the bottom of the lower frame. It is equipped with a signal acquisition port and a signal output interface. The signal acquisition port is connected to the temperature sensor and the displacement sensor respectively, while the signal output interface is connected to the electric control triplet and the servo motor respectively to control and adjust the working status of the electric control triplet and the servo motor.

[0014] Preferably, a lighting lamp and an electronically controlled safety lock are also fixedly installed at the top of the upper frame, and an operation button panel, a three-color light, a touch screen and a display are also fixedly installed on the front right side of the upper frame;

[0015] The operation button panel is used to control at least the switching of servo motors, lighting, and electric safety locks on the test bench, as well as the emergency stop of the servo motors;

[0016] The tri-color LEDs are connected to the industrial control computer and are used to monitor the test status of the test bench.

[0017] The touchscreen, connected to the industrial computer, is used for manually adjusting setting parameters and displaying monitoring channel parameters;

[0018] The monitor, connected to the industrial control computer, is used to display the operating parameters of the test process.

[0023] This invention relates to a test bench for clutch actuator seal rings, comprising a main frame, a cam-linkage mechanism, a large seal ring assembly fixture, a small seal ring assembly fixture, a servo motor, an electrical control triplet, a leakage tester, and an industrial computer. The structure is simple. When two seal rings of different sizes are nested around the large and small seal ring assembly fixtures respectively, the servo motor drives the cam-linkage mechanism to oscillate axially, serving as the driving component for the entire test. This allows for testing the durability of the seal rings. Furthermore, the test bench can adjust the servo motor speed via the industrial computer, enabling testing of the seal rings under high-pressure gas and different operating frequencies (simulating various load conditions). The testing operation is very simple. Moreover, because the cam-linkage mechanism is equipped with two assembly fixtures of different sizes at both ends, it can simultaneously test seal rings of different sizes, resulting in high testing efficiency and good adaptability.

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] See Figure 1-4 In this embodiment, a test bench for clutch actuator seals is provided, the test bench comprising:

[0031] - The main frame of the test bench consists of two parts: an upper frame 4 and a lower frame 1. Both the upper frame 4 and the lower frame 1 are made of corrosion-resistant metal profiles, which have strong structural strength and hardness and can effectively support the test equipment and facilities on the test bench.

[0032] - The cam linkage mechanism 12 is fixedly installed on the platform at the bottom of the upper frame 4. The bottom of the cam linkage mechanism 12 is connected to a servo motor 19 that drives it to swing axially repeatedly. The servo motor 19 is fixedly connected to the lower frame 1 through a mounting bracket. The two ends of the cam linkage mechanism 12 are respectively connected to a large sealing ring assembly fixture 13 and a small sealing ring assembly fixture 5. Each assembly fixture can install three sealing rings of the same specification for testing. Specifically, the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5 serve as assembly fixtures for sealing ring products. When two types of sealing rings of different sizes are nested around the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5, the cam linkage mechanism 12 can be driven by the servo motor 19 to swing axially repeatedly, serving as the driving component for the entire test, thereby testing the durability of the sealing ring.

[0033] - The electric control triplet 15 is fixedly installed at the bottom left end of the lower frame 1. The air inlet of the electric control triplet 15 is connected to the air source of the assembly line through the air inlet pipe. The two air outlets of the electric control triplet 15 are respectively connected to the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5 through the air supply pipe, so as to regulate the gas pressure inside the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5, thereby simulating the durability performance of the sealing ring under various load conditions.

[0034] - Leak tester 17 is fixedly installed on the left front side of the bottom of the lower frame 1. The detection interface of leak tester 17 is connected to the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5 through a set of detection gas tubes, and is used to monitor the leakage of gas in the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5.

[0035] See Figure 2 In this embodiment, the test bench also includes two sets of temperature sensors, one set of displacement sensors 18, and an industrial control computer 2;

[0036] Two sets of temperature sensors are provided. One set of temperature sensors is fixedly installed inside the large sealing ring assembly fixture 13 (not shown) to monitor the temperature inside the cavity of the large sealing ring assembly fixture 13, while the other set of temperature sensors is fixedly installed inside the small sealing ring assembly fixture 5 (not shown) to monitor the temperature inside the cavity of the small sealing ring assembly fixture 5. Specifically, each set of temperature sensors has at least three sensors, which are distributed in different positions of the fixture to ensure the accuracy of temperature monitoring inside the cavity.

[0037] A set of displacement sensors 18 are symmetrically fixed on the platforms on both sides of the cam linkage mechanism 12 to detect the position of the connecting shaft of the cam linkage mechanism 12, so as to ensure that the cam linkage mechanism can operate stably.

[0038] The industrial control computer 2 is fixedly installed on the right front side of the bottom of the lower frame 1. It is equipped with a signal acquisition port and a signal output interface. The signal acquisition port is connected to the temperature sensor and the displacement sensor 18, respectively, while the signal output interface is connected to the electric control triplet 15 and the servo motor 19, respectively, to control and adjust the working state of the electric control triplet 15 and the servo motor 19. Specifically, the temperature sensor sends the temperature data monitored in the cavity of the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5, and the axial rocking displacement data monitored by the displacement sensor 18 on the cam linkage mechanism to the industrial control computer 2. After processing, the industrial control computer 2 controls the speed of the servo motor 19, thereby simulating the durability performance of the sealing ring under various load conditions.

[0039] See Figure 2 In this embodiment, a lighting lamp 11 and an electronically controlled safety lock 10 are also fixedly installed at the top of the upper frame 4, and an operation button panel 6, a three-color lamp 9, a touch screen 7 and a display 8 are also fixedly installed on the front right side of the upper frame 4.

[0040] The operation button panel 6 is used to control at least the switching of the servo motor 19, the lighting lamp 11, and the electric safety lock 10 on the test bench, as well as the emergency stop of the servo motor 19;

[0041] The tri-color light 9 is connected to the industrial control computer 2 and is used to monitor the test status of the test bench;

[0042] Touch screen 7, connected to industrial computer 2, is used for manually adjusting setting parameters and displaying monitoring channel parameters;

[0043] Display 8 is connected to industrial computer 2 and is used to display the operating parameters of the test process.

[0044] See Figure 2In this embodiment, a power distribution box 14 is also fixedly installed on the left end of the lower frame 1. The power distribution box 14 provides power to at least the electrical control triplet 15, the leakage tester 17, the industrial computer 2 and the servo motor 19 on the test bench.

[0045] See Figure 1-2 In this embodiment, a control keyboard 3 connected to the industrial control computer 2 is also fixedly installed on the front right side of the top of the lower frame 1.

[0046] See Figure 1-2 In this embodiment, leveling bases 16 are fixedly installed at the bottom corners of the lower frame 1. The leveling bases 16 can quickly level the test bench to ensure the stability of the test bench during the sealing ring test.

[0047] It should be noted that the test process for the clutch actuator seal ring test bench of the present invention is as follows:

[0048] During testing: The tester assembles the corresponding number and specifications of sealing rings around the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5. Then, the tester controls the electric control triplet 15 to charge the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5 with high-pressure gas at the required pressure. Then, the tester controls the servo motor 19 to drive the cam linkage mechanism 12 to swing axially between the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5 repeatedly, which serves as the driving component for the entire test. This allows for durability testing of the sealing rings around the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5.

[0049] After a period of testing (completion): the tester can monitor the amount of gas leakage in the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5 through the leakage tester 17, thereby judging the degree of wear of the outer sealing rings of the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5, and thus helping to judge the durability of the sealing rings.

[0050] Of course, during the testing process: the tester can also adjust the gas pressure inside the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5 through the electronic control triplet 15. The temperature sensor will send the temperature data monitored in the cavity of the large sealing ring assembly fixture 13 and the small sealing ring assembly fixture 5, as well as the axial rocking displacement data monitored by the displacement sensor 18 on the cam linkage mechanism, to the industrial control computer 2. After processing, the industrial control computer 2 controls the speed of the servo motor 19, thereby simulating the durability performance of the sealing ring under various load conditions (operating frequency), which can effectively improve the testing breadth of the sealing ring on the test bench.
