Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber detection, in particular to a quality detection device for automobile shock absorber processing. Background Art

[0002] A car's shock absorber is a crucial component in the suspension system. Its primary function is to dampen the oscillations caused by the spring's rebound after absorbing shock, as well as impacts from the road surface. When a vehicle travels over uneven surfaces, the shock absorber's internal piston moves, controlling the flow of oil within the cylinder, thereby generating a damping force to attenuate the resulting vibrations. This damping force effectively reduces spring rebound and vehicle body roll, maintaining good wheel-to-ground contact and improving driving stability and ride comfort.

[0003] Therefore, it is crucial to control the quality of automobile shock absorbers during their processing. However, existing automobile shock absorbers are usually inspected manually during the inspection process. The use of the above-mentioned inspection method will lead to reduced inspection efficiency. At the same time, manual inspection cannot intuitively reflect the shock absorber data in a timely manner, thereby reducing the accuracy of the inspection.

[0004] Therefore, the utility model provides a quality inspection device for automobile shock absorber processing, which is used to solve the above problems. Utility Model Content

[0005] Existing automobile shock absorbers usually adopt manual inspection during the inspection process. The use of the above-mentioned inspection method will lead to reduced inspection efficiency. At the same time, manual inspection cannot timely and intuitively reflect the shock absorber data, thereby reducing the accuracy of the inspection. The utility model provides a quality inspection device for automobile shock absorber processing.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A quality inspection device for automobile shock absorber processing, comprising a testing box, a fixing frame, and a vibrator. The fixing frame is installed in the testing box; the vibrator is installed at the bottom of the testing box. The device is characterized by further comprising a detection mechanism installed inside the testing box. The detection mechanism is used to convert the shock absorption effect of the shock absorber into the displacement of the sensor, thereby ensuring the accuracy of the detection.

[0008] Pre-pressure is applied to the shock absorber in advance through the pressure component in the detection mechanism, thereby simulating cars of different weights. The shock absorber is then vibrated by the vibrator at its bottom. The vibrating shock absorber drives the displacement sensor to move up and down in the sensing plate, and the shock absorption effect of the detection shock absorber is converted into the displacement of the sensor, thereby improving the detection efficiency and accuracy.

[0009] As a preferred technical solution of the present utility model, the detection mechanism includes a pressure component, a fixed plate, a mobile rod, a displacement sensor, a limit groove and a sensing piece. The pressure component is installed on the top of the detection box, the fixed plate is installed above the shock absorber, the fixed plate is installed with a mobile rod, and the displacement sensor is installed on the mobile rod; limit grooves are provided on both sides of the detection box, the limit grooves are installed in the sensing pieces, and the displacement sensor is clamped in the limit grooves;

[0010] The staff places the shock absorber in the test box, then fixes the shock absorber with a fixing frame, operates the pressure component to apply a pre-pressure to the fixed shock absorber, and the pressure component squeezes the fixed plate. Then the staff operates the vibrator to vibrate to simulate the driving environment. At this time, the shock absorber will drive the fixed plate to move up and down during the vibration process, and the fixed plate moving up and down will drive the moving rod to move up and down. The moving rod moving up and down will drive the displacement sensor to move up and down in the limit slot, thereby making the displacement sensor contact the sensor plates at different positions. The sensor plates transmit the signals to the control mechanism, and the control mechanism converts the signals into specific data and displays them on the operating table, thereby realizing the detection of the shock absorber.

[0011] As a preferred technical solution of the present invention, the pressure assembly includes an electric push rod and a pressure block, the electric push rod is installed inside the detection mechanism, the end of the electric push rod is installed with a pressure block, and the pressure block is in contact with the fixed disk;

[0012] The staff controls the extension and retraction of the electric push rod to apply different degrees of pressure to the pressure block, thereby simulating cars of different tonnages, and then cooperates with the detection components to realize the detection of the shock absorber.

[0013] As a preferred technical solution of the present utility model, a rotating motor is installed on the electric push rod, and a clamping block is installed on the rotating motor, and the clamping block is in contact with the pressure block;

[0014] By pressing the shock absorber to a certain value and then controlling the rotation of the motor, the clamping block and the pressure block are no longer in contact, and the pressure on the shock absorber disappears instantly. At this time, the shock absorber will drive the displacement sensor to move up and down until it stops. This method can quickly detect the working effect of the shock absorber at the extreme position, thereby further improving the accuracy of the detection.

[0015] As a preferred technical solution of the present invention, a reset spring is installed between the detection box and the pressure block, and the reset spring is used to quickly reset the pressure block when the clamping block rotates.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. During the shock absorber testing process, pre-pressure can be applied to the shock absorber in advance through the pressure component in the testing mechanism, thereby simulating cars of different weights. The shock absorber is then vibrated by the vibrator at the bottom. The vibrating shock absorber drives the displacement sensor to move up and down in the sensing piece, thereby converting the shock absorption effect of the testing shock absorber into the displacement of the sensor, thereby improving the detection efficiency and accuracy.

[0019] 2. During the shock absorber testing process, when the shock absorber is pressed to a certain value, the rotating motor is controlled to rotate, so that the clamping block and the pressure block are not in contact, and the pressure on the shock absorber disappears instantly. At this time, the shock absorber will drive the displacement sensor to move up and down until it stops. This method can quickly detect the working effect of the shock absorber at the extreme position, thereby further improving the accuracy of the detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0026] The utility model discloses a quality inspection device for automobile shock absorber processing, which is mainly used in the scenario of quality inspection of automobile shock absorbers during processing.

[0027] Reference Figures 1-4 A quality inspection device for automobile shock absorber processing includes a testing box 1, a fixing frame 2 and a vibrator 3. The fixing frame 2 is installed in the testing box 1; the vibrator 3 is installed at the bottom of the testing box 1; it is characterized in that it also includes a detection mechanism 4, which is installed inside the testing box 1. The detection mechanism 4 is used to convert the shock absorption effect of the shock absorber into the displacement of the sensor, thereby ensuring the accuracy of the detection.

[0028] In this embodiment, pre-pressure can be applied to the shock absorber in advance through the pressure component 41 in the detection mechanism 4, thereby simulating cars of different weights, and then the shock absorber is vibrated by the vibrator 3 at its bottom. The vibrating shock absorber drives the displacement sensor 44 to move up and down in the sensing plate 46, and then the shock absorption effect of the detection shock absorber is converted into the displacement of the sensor, thereby improving the detection efficiency and the accuracy of the detection.

[0029] Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, the detection mechanism 4 includes a pressure component 41, a fixed plate 42, a moving rod 43, a displacement sensor 44, a limiting groove 45 and a sensing piece 46. The pressure component 41 is installed on the top of the detection box 1, and the pressure component 41 is used to apply pressure to the shock absorber; the fixed plate 42 is installed above the shock absorber, and the fixed plate 42 is used to move up and down with the up and down movement of the shock absorber; the fixed plate 42 is installed with a moving rod 43, and the moving rod 43 is used to drive the displacement sensor 44 to move; the displacement sensor 44 is installed on the moving rod 43; the displacement sensor 44 is used to cooperate with the sensing piece 46 to record the movement data of the shock absorber in time; limiting grooves 45 are provided on both sides of the detection box 1, and the limiting grooves 45 are used to limit the moving direction of the displacement sensor 44; the sensing piece 46 is installed in the limiting groove 45, and the sensing piece 46 is used to cooperate with the displacement sensor 44 to record the movement data of the shock absorber; the displacement sensor 44 is clamped in the limiting groove 45;

[0030] During operation, the staff first places the shock absorber in the test box 1, then fixes the shock absorber through the fixing frame 2, operates the pressure component 41 to apply a pre-pressure to the fixed shock absorber, and the pressure component 41 squeezes the fixed plate 42. Then the staff operates the vibrator 3 to vibrate to simulate the driving environment. At this time, the shock absorber will drive the fixed plate 42 to move up and down during the vibration process. The fixed plate 42 that moves up and down will drive the moving rod 43 to move up and down. The moving rod 43 that moves up and down will drive the displacement sensor 44 to move up and down in the limit groove 45, thereby making the displacement sensor 44 contact the sensing piece 46 at different positions. The sensing piece 46 transmits the signal to the control mechanism, and the control mechanism converts the signal into specific data and displays it on the operating table, thereby realizing the detection of the shock absorber;

[0031] By adopting the above-mentioned detection method, pre-pressure is applied to the shock absorber in advance through the pressure component 41 in the detection mechanism 4, thereby simulating cars of different weights, and then the shock absorber is vibrated by the vibrator 3 at its bottom. The vibrating shock absorber drives the displacement sensor 44 to move up and down in the sensing plate 46, and then the shock absorption effect of the detection shock absorber is converted into the displacement of the sensor, thereby improving the detection efficiency and the accuracy of the detection.

[0032] Specifically, refer to Figure 2 and Figure 4 The pressure assembly 41 includes an electric push rod 411 and a pressure block 412. The electric push rod 411 is installed inside the detection mechanism 4 and is used to apply pressure to the pressure block 412. A pressure block 412 is installed at the end of the electric push rod 411. The pressure block 412 contacts the fixed disk 42 and is used to apply pressure to the fixed disk 42.

[0033] During operation, the staff controls the extension and contraction of the electric push rod 411 to apply different degrees of pressure to the pressure block 412, thereby simulating cars of different tonnages, and then cooperates with the detection component to realize the detection of the shock absorber.

[0034] Specifically, refer to Figure 4 The electric push rod 411 is equipped with a rotating motor 413, which is used to control the rotation of the clamping block 414; the rotating motor 413 is equipped with a clamping block 414, which is used to apply pressure to the pressure block 412; the clamping block 414 is in contact with the pressure block 412;

[0035] During operation, the electric push rod 411 transfers pressure to the rotating motor 413, the rotating motor 413 transfers pressure to the clamping block 414, and the clamping block 414 transfers pressure to the pressure block 412, thereby achieving compression of the shock absorber; when contact compression is required at the same time, if the electric push rod 411 is retracted, the shock absorber will expand as the electric push rod 411 is retracted during the retraction process. Therefore, it is necessary to make the rotating motor 413 rotate the clamping block 414 to cancel the clamping of the pressure block 412, and then instantly withdraw the pressure of the electric push rod 411, thereby achieving high-quality detection of the shock absorber.

[0036] By pressing the shock absorber to a certain value, the rotating motor 413 is controlled to rotate, so that the clamping block 414 and the pressure block 412 are not in contact, and the pressure on the shock absorber disappears instantly. At this time, the shock absorber will drive the displacement sensor 44 to move up and down until it stops. This method can quickly detect the working effect of the shock absorber at the extreme position, thereby further improving the accuracy of the detection.

[0037] Specifically, refer to Figure 2 and Figure 4 A reset spring 415 is installed between the detection box 1 and the pressure block 412. The reset spring 415 is used to quickly reset the pressure block 412 when the clamping block 414 rotates.

[0038] Specifically, refer to Figure 2 The detection box 1 is provided with a temperature regulating mechanism 5, a blower mechanism 6 and a water spraying mechanism 7; the temperature regulating mechanism 5 is used to regulate the temperature inside the detection box 1; the blower mechanism 6 is used to simulate a strong wind environment; the water spraying mechanism 7 is used to simulate a rainy day environment, thereby realizing the detection of multiple environments of the shock absorber.

[0039] During operation, the staff first places the shock absorber in the test box 1, then fixes the shock absorber through the fixing frame 2, operates the pressure component 41 to apply a pre-pressure to the fixed shock absorber, and the pressure component 41 squeezes the fixed plate 42. Then the staff operates the vibrator 3 to vibrate to simulate the driving environment. At this time, the shock absorber will drive the fixed plate 42 to move up and down during the vibration process. The fixed plate 42 that moves up and down will drive the moving rod 43 to move up and down. The moving rod 43 that moves up and down will drive the displacement sensor 44 to move up and down in the limit groove 45, thereby making the displacement sensor 44 contact the sensing piece 46 at different positions. The sensing piece 46 transmits the signal to the control mechanism, and the control mechanism converts the signal into specific data and displays it on the operating table, thereby realizing the detection of the shock absorber;

[0040] When it is necessary to detect the extreme position of the shock absorber, the electric push rod 411 transfers the pressure to the fixed sleeve, the fixed sleeve transfers the pressure to the clamping block 414, and the clamping block 414 transfers the pressure to the pressure block 412, thereby achieving compression of the shock absorber; when contact compression is required at the same time, if the electric push rod 411 is retracted, the shock absorber will expand as the electric push rod 411 is retracted during the retraction process. Therefore, it is necessary to make the rotating motor 413 rotate the clamping block 414 to cancel the clamping of the pressure block 412, and then instantly withdraw the pressure of the electric push rod 411, thereby achieving high-quality detection of the shock absorber.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
