Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
A first embodiment of the present invention provides a method for detecting an ABS energy accumulator, where the method is applied to the ABS energy accumulator, and as shown in fig. 1, the ABS energy accumulator includes: a stop cover 101, a spring 102, a piston 103 and a cavity 104 with an opening; the baffle cover 101 is embedded at the opening of the cavity 104; one end of the spring 102 is connected with the gear cover 101, and the other end is connected with the piston 103; the piston 103 is arranged in the cavity 104 and is used for sliding on the cavity wall of the cavity 104; the bottom of the cavity 104 is provided with an oil port 105.
As shown in fig. 2, the method for detecting the ABS accumulator includes:
s201: injecting high-pressure gas through an oil port 105 of the ABS energy accumulator;
s202: carrying out first detection on the ABS energy accumulator to obtain a first detection result;
s203: after the high-pressure gas in the ABS energy accumulator is exhausted, the high-pressure gas is injected again through the oil port 105 of the ABS energy accumulator;
s204: carrying out secondary detection on the ABS energy accumulator to obtain a second detection result;
s205: and comparing the first detection result with the second detection result to determine whether the ABS energy accumulator is abnormal or not.
It should be explained that, the high pressure gas is injected into the ABS accumulator through the oil port 105 of the ABS accumulator, the high pressure gas will push the piston 103 to slide, the piston 103 compresses the spring 102, and the spring 102 transmits the motion of the piston 103 to the accumulator cover 101. The ABS accumulator is detected by using the motion principle of the piston 103, the spring 102 and the stop cover 101.
The ABS energy accumulator is detected in a high-pressure gas mode, and the ABS energy accumulator is efficiently detected on the premise of not losing or damaging the ABS energy accumulator. Even if the ABS energy accumulator is detected to be abnormal, the failure of the ABS energy accumulator can be confirmed without destroying the body structure, and the detection method can be applied to production equipment. The detection method of the invention achieves high-efficiency and low-cost detection.
In a specific implementation process, step S202 includes:
the high-pressure gas pushes the piston 103 at the initial position to the stopper 101 by compressing the spring 102; the vibration of the cover 101 is detected by an environment detection sensor provided on the cover 101, and a first detection result is obtained.
In a specific implementation process, step S204 includes:
the piston 103 is pushed to the stop cover 101 by the high-pressure gas injected again through the compression spring 102; the vibration of the stopper 101 is detected by the environment detection sensor, and a second detection result is obtained.
Preferably, the initial position is a position where the piston 103 is at the bottom inside the cavity 104.
Preferably, the environment detection sensor is a vibration sensor, and the environment detection sensor can also adopt a pressure sensor.
Specifically, the first detection process is as follows: high-pressure gas is injected into the ABS accumulator through the oil port 105 of the ABS accumulator, and the high-pressure gas pushes the piston 103 at the initial position to compress the spring 102 due to the gradual increase of the volume of the high-pressure gas. The high-pressure gas gradually pushes the piston 103 at the initial position to the stopper cover 101 by the compression of the spring 102, and the stopper cover 101 is vibrated at the moment when the piston 103 touches the stopper cover 101. The vibration value is acquired through the vibration sensor, and the acquired vibration value is a first detection result.
After the first detection result is collected, step S203 may be executed to evacuate the high-pressure gas in the ABS energy accumulator to prepare for the re-detection.
In step S204, the process of the second detection is identical to the process of the first detection, as follows:
high-pressure gas is injected into the ABS accumulator through the oil port 105 of the ABS accumulator, and the high-pressure gas pushes the piston 103 at the initial position to compress the spring 102 due to the gradual increase of the volume of the high-pressure gas. The high-pressure gas gradually pushes the piston 103 to the stopper cover 101 by the compression of the spring 102, and the stopper cover 101 is vibrated at the moment when the piston 103 touches the stopper cover 101. And acquiring the vibration value through a vibration sensor, wherein the vibration value is a second detection result.
It is noted that the piston is in the initial position, i.e. at the bottom in the chamber, at the first test. When the detection is carried out again, the position of the piston in the cavity cannot be determined, so that the detection must be carried out for the second time to judge whether the piston can freely slide or not and whether the ABS energy accumulator functions normally or not.
The invention adopts the vibration sensor or the pressure sensor, has the advantages of various types, low cost, better precision and the like, is beneficial to detecting the ABS energy accumulator and can efficiently collect the impact force of the piston on the stop cover.
In a specific implementation process, step S205 includes:
if the first detection result is the same as the second detection result and the first detection result is greater than or equal to the threshold value, determining that the ABS energy accumulator is in a normal state; and if the first detection result is different from the second detection result, or the first detection result is smaller than the threshold value, or the second detection result is smaller than the threshold value, determining that the ABS energy accumulator is in an abnormal state.
Specifically, through twice detection, whether the piston of the ABS energy accumulator can move freely or not and whether the function of the ABS energy accumulator is normal or not can be judged. If the first detection result is basically the same as the second detection result and the first detection result is greater than or equal to the threshold value, it is indicated that the ABS energy accumulator piston can move freely and the energy accumulation function is normal. If the difference between the first detection result and the second detection result is large, or the first detection result is smaller than the threshold, or the second detection results are both smaller than the threshold, the situation that the piston is blocked by four, the energy accumulator fails, and the assembling quality of the energy accumulator is poor is shown.
In practical application, in the detection process of a qualified ABS energy accumulator, the acquired vibration value is between 52 and 82N, in the detection process of an unqualified ABS energy accumulator, the acquired vibration value is between 5 and 5.8N, and the threshold value is set to be 30N, so that the good product and the defective product of the ABS energy accumulator can be completely distinguished.
Before injecting high-pressure gas through the oil port 105 of the ABS accumulator, the detection method of the present invention further includes:
the air compressor compresses air, and the compressed air is stored in the air tank, so that the air in the air tank is injected into the ABS energy accumulator.
Preferably, the high pressure gas is air. In addition, nitrogen can be used as the high-pressure gas.
Specifically, the air compressor can be made of local materials, uses air as a medium, compresses air, and stores the air into the air tank, so that the air in the air tank is injected into the ABS energy accumulator. Therefore, the invention takes gas as a medium to test whether the ABS energy accumulator is abnormal or not under the condition of not damaging the ABS energy accumulator body. Even on an ABS assembly line, the invention can also detect and test each assembled ABS energy accumulator; the accuracy of the detection result is high, the subsequent packaging, transportation and the like of the ABS energy accumulator after the test are not influenced, and the method is suitable for production equipment. The invention can accurately check the ABS energy accumulator with high efficiency and low cost.
For a more complete description of the detection method of the ABS energy accumulator, see fig. 3, the following is shown:
the inside of the dotted line frame is the internal structure of the ABS body, wherein EV1-EV4 is a pressure increasing valve (normally open valve), AV1-AV4 is a pressure reducing valve (normally closed valve), P1 and P2 are oil return pumps, M is a motor, R1 and R2 are energy accumulators, and each energy accumulator comprises a cavity, a spring, a piston, a stop cover and the like.
On the external line, Y1-Y7 are solenoid valves, Y8-Y9 are manual valves (line pressure can be manually reduced to atmospheric pressure when the solenoid valves fail), B1, B4, B5 are pressure sensors, B2, B3 are vibration sensors, and F1, F2, F3 are filters. Since the high pressure gas is at a high pressure of 200Bar, the pressure is adjusted to 60Bar by a pressure regulating valve at the air inlet.
The air intake operation is as follows: the following valves on the external piping were opened: y1, Y2, Y3, Y5 and Y6 are used for introducing high-pressure gas into inlets of pressure reducing valves AV1-AV4 through oil ports, and EV1-EV4 are normally open valves and default to an open state. The ABS is controlled, the pressure reducing valves AV1-AV4 are opened, external 60bar high-pressure gas is charged into the energy accumulator when the pressure reducing valves are opened, the energy accumulator piston is pushed to compress the spring, and the spring transmits the impact vibration to the stop cover. The shock sensor at the hood will detect this impact force.
Because two detections are needed, after the first detection is finished, Y1 is closed, and the high-pressure gas source is cut off; opening Y4, Y7 (at which time Y2, Y3, Y5, Y6 continue to open) exhausts high pressure gas in the external piping and in the ABS accumulator cavity (at which time AV1-AV4 continue to open) to the atmosphere. And after the exhaust is finished, performing primary air intake and detection on the ABS energy accumulator through the process.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
1. the invention takes gas as a medium to detect the ABS energy storage deflection without damaging the ABS body structure, so the method can be carried out on an ABS assembly line, can test each ABS and is suitable for production equipment.
2. The invention uses gas as medium for detection, does not affect the subsequent packaging and transportation links of ABS products, and the gas adopts air or nitrogen, thereby improving the detection efficiency, reducing the loss of ABS and saving the cost.
3. The invention has the characteristics of easy operation, high efficiency, accurate detection rate and the like, thereby effectively improving the quality of ABS products.
