Description

Technical Field

[0001] The present invention relates to the technical field of shock absorber pressure detection, in particular to a corrosion-resistant pressure detection device for an automobile shock absorber and a use method thereof. Background Art

[0002] The suspension system is the general term for all load-transmitting connections between a vehicle's frame and axles or wheels. Its function is to transmit forces and torques acting between the wheels and frame, cushion the impact forces transmitted to the frame or body by uneven roads, and attenuate the resulting vibrations, ensuring smooth driving. A typical suspension system consists of elastic elements, guide mechanisms, and shock absorbers. Some systems also include buffer blocks and anti-roll bars. Elastic elements can take the form of leaf springs, air springs, coil springs, and torsion bars. In a vehicle's suspension, shock absorbers are always used in conjunction with springs. When we press down on a corner of the vehicle, it's the springs that are actually compressed, causing the corresponding swing arm to swing. When the body is released, the spring force causes the vehicle to rebound. Shock absorbers dampen this rebound, stabilizing the vehicle after the rebound. Without shock absorbers, the springs would be compressed again after the rebound, causing the vehicle to rebound again, resulting in the vehicle stabilizing after repeated rebounds. Therefore, shock absorbers provide a damping function for the springs in a vehicle's suspension during rebound. In order to quickly attenuate the vibration of the frame and body and improve the smoothness and comfort of the car's driving, shock absorbers are generally installed on the car's suspension system. The double-acting cylinder shock absorbers are widely used in cars.

[0003] After the existing automobile shock absorbers are produced, they need to be tested for the pressure value they can withstand. During this process, a device is usually used to press down on the automobile shock absorber to test the pressure value the automobile shock absorber can withstand. However, when the automobile shock absorber is no longer pressed down, the elastic element inside the automobile shock absorber will reset, and the resilience of the elastic element inside the automobile cannot be tested at this time.

[0015] A method for using a corrosion-resistant pressure detection device for an automobile shock absorber comprises the following steps:

[0016] Step 1: Pressure detection;

[0017] Step 2: Stable clamping;

[0018] Step 3: Resilience test;

[0019] Step 4: Corrosion testing.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, when the two moving frames approach each other, the moving frame drives the rotating bar to move, which is limited by the limiting rod. The rotating bar drives the concave shell to slide along the outer wall of the limiting rod. During the movement of the concave shell, it will come into contact with the top of the sliding bending plate, squeeze the sliding bending plate, and make the sliding bending plate move laterally. During the movement of the sliding bending plate, the bottom end of the automobile shock absorber is no longer supported. When the automobile shock absorber is completely out of contact with the top of the sliding bending plate, the elastic structure inside the automobile shock absorber causes the bottom end of the automobile shock absorber to move toward the inside of the working shell, thereby being able to detect the rebound elasticity of the elastic material inside the automobile shock absorber, thereby improving the accuracy of the detection. At this time, the clamped automobile shock absorber shell can provide stability for the automobile shock absorber rebound detection, thereby preventing the automobile shock absorber shell from slightly shaking during the automobile shock absorber rebound detection.

[0022] (2) The present invention clamps the two ends of the automobile shock absorber on the inner walls of the two positioning frames, and the bottom end of the automobile shock absorber is placed on the top of the sliding bending plate. The electric telescopic rod is started, and the electric telescopic rod drives the sliding plate to vertically descend along the outer wall of the fixed column, and the sliding plate drives the positioning frame to descend, and the positioning frame drives the automobile shock absorber to descend. Under the reaction force of the sliding bending plate, the automobile shock absorber can simulate the pressure conditions it bears in actual work. When the sliding plate descends, the sliding plate will contact the top of the slider, causing the slider to vertically descend. The slider drives the rotating rod to move downward, and is limited by the limiting groove. The rotating rod drives the sliding shell to move along the inner wall of the limiting groove. The sliding shell drives the moving plate to move, and the moving plate drives the cross bar to move. The cross bar drives the special-shaped clamping block to move. The two special-shaped clamping blocks approach each other, thereby clamping the outer wall of the bottom end of the automobile shock absorber, preventing the automobile shock absorber from shaking during the pressure detection process, and improving the accuracy of the automobile shock absorber detection.

[0023] (3) In the present invention, when the shell of the automobile shock absorber is in the process of descending, the bottom end of the automobile shock absorber can contact the inclined surface of the special-shaped clamping block, which can drive the cross bar to move slightly, and the cross bar drives the moving plate to move slightly toward the inside of the sliding shell. At this time, the two special-shaped clamping blocks can clamp the outer wall of the shell of the automobile shock absorber, further improving the stability of the automobile shock absorber during pressure testing. In addition, the sliding shell can drive the L-shaped rod to move during movement, and the L-shaped rod will contact one side of the moving frame during movement, so that the moving frame slides along the inner wall of the strip groove, and the moving frame drives the round rod to move, and the round rod drives the arc plate to move. The two arc plates approach each other and will contact the side wall of the special-shaped clamping block. Because the special-shaped clamping block is made of flexible material, the special-shaped clamping block is deformed, thereby improving the clamping effect of the special-shaped clamping block on the automobile shock absorber shell.

[0024] (4) According to the present invention, when the bottom end of the automobile shock absorber enters the interior of the working shell, it will come into contact with the corrosive liquid inside the working shell, thereby performing corrosion resistance testing on the automobile shock absorber. When the shell of the automobile shock absorber squeezes the special-shaped clamping block, the special-shaped clamping block drives the cross bar to move, and the cross bar drives the moving plate to move inside the sliding shell. Because two strip holes are provided at the bottom of the sliding shell, the connecting gear rack is prevented from getting stuck during movement. The moving plate drives the connecting gear rack to move, and the connecting gear rack contacts the outer wall of the gear during movement, causing the gear to rotate. The gear drives the circular sleeve to rotate, and the circular sleeve drives the stirring rack to rotate. During the rotation of the stirring rack, the corrosive liquid inside the working shell is stirred, thereby improving the fluidity of the corrosive liquid and improving the overall corrosiveness of the corrosive liquid to the bottom end of the automobile shock absorber.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the sliding plate 51 is in the process of descending, the sliding plate 51 will come into contact with the top of the slider 561, causing the slider 561 to descend vertically. The slider 561 drives the rotating rod 562 to move downward. It is limited by the limiting groove 565, and the rotating rod 562 drives the sliding shell 564 to move along the inner wall of the limiting groove 565. The sliding shell 564 drives the moving plate 566 to move, the moving plate 566 drives the cross bar 571 to move, the cross bar 571 drives the special-shaped clamping block 572 to move, and the two special-shaped clamping blocks 572 approach each other, thereby clamping the bottom outer wall of the automobile shock absorber 55 to prevent shaking during the pressure detection of the automobile shock absorber 55, thereby improving the detection accuracy of the automobile shock absorber 55.

A second spring 576 is fixedly connected between the two moving frames 574. A round rod 577 is fixedly connected to the side of the moving frame 574 close to the second spring 576. An arc plate 578 is fixedly connected to the end of the round rod 577 away from the moving frame 574. The sliding shell 564 can drive the L-shaped rod 573 to move during movement. The L-shaped rod 573 will move with the moving frame 574 during movement. One side of the movable frame 574 comes into contact, causing the movable frame 574 to slide along the inner wall of the strip groove 575, and the movable frame 574 drives the round rod 577 to move, and the round rod 577 drives the arc plate 578 to move. The two arc plates 578 approach each other and come into contact with the side wall of the special-shaped clamping block 572.

[0044] A detection assembly 58 is provided on the side wall of the support plate 2. The detection assembly 58 includes a limit rod 581 fixedly connected to both ends of one side of the support plate 2. The outer wall of one end of the limit rod 581 is slidably connected to a concave shell 583, and the inner wall of the concave shell 583 is rotatably connected to the two ends of the rotation bar 582.

[0045] One end of the rotating bar 582 is rotatably connected to the top of the moving frame 574, and a sliding bending plate 584 is passed through and slidably connected to one side of the working shell 1, so that the two ends of the automobile shock absorber 55 are clamped at the inner walls of the two clamping frames 54, and the bottom end of the automobile shock absorber 55 is placed on the top of the sliding bending plate 584, and the electric telescopic rod 4 is started. The electric telescopic rod 4 drives the sliding plate 51 to vertically descend along the outer wall of the fixed column 3, and the sliding plate 51 drives the clamping frame 54 to descend, and the clamping frame 54 drives the automobile shock absorber 55 to descend, and is subjected to the reaction force of the sliding bending plate 584, so that the automobile shock absorber 55 can simulate the pressure conditions in actual work. The top center of the sliding bending plate 584 contacts the bottom of the automobile shock absorber 55, and one side of the bottom end of the sliding bending plate 584 is fixedly connected to an extrusion spring 585, and one end of the extrusion spring 585 is fixedly connected Connected to one side of the inner wall of the working shell 1, when the two moving frames 574 approach each other, the moving frame 574 drives the rotating bar 582 to move, and is limited by the limiting rod 581. The rotating bar 582 drives the concave shell 583 to slide along the outer wall of the limiting rod 581. During the movement of the concave shell 583, it will contact the top of the sliding bending plate 584, squeeze the sliding bending plate 584, and make the sliding bending plate 584 move laterally. During the movement of the sliding bending plate 584, it no longer supports the bottom end of the automobile shock absorber 55. When the automobile shock absorber 55 is completely out of contact with the top of the sliding bending plate 584, it is affected by the elastic structure inside the automobile shock absorber 55, so that the bottom end of the automobile shock absorber 55 moves toward the inside of the working shell 1, thereby being able to detect the resilience of the elastic material inside the automobile shock absorber 55, thereby improving the accuracy of the detection.

[0046] In embodiment 2, a stirring assembly 59 is provided at the bottom of the movable plate 566. The stirring assembly 59 includes a connecting tooth frame 591 fixedly connected to the two ends of the bottom of the movable plate 566. Clamping holes 592 are respectively opened around the top of the working shell 1. The outer wall of one end of the connecting tooth frame 591 is slidably connected to the inner wall of the clamping hole 592.

[0047] The bottom of the connecting gear rack 591 is meshedly connected with a gear 596, the inner wall of the gear 596 is fixedly connected with a circular sleeve 593, the inner wall of the circular sleeve 593 is rotatably connected with a fixed rod 594, both ends of the fixed rod 594 are fixedly connected to the inner wall of the working shell 1, and the middle end of the outer wall of the circular sleeve 593 is fixedly connected with a stirring rack 595. When the bottom end of the automobile shock absorber 55 enters the interior of the working shell 1, it will come into contact with the corrosive liquid inside the working shell 1, thereby performing corrosion resistance testing on the automobile shock absorber 55. When the shell of the automobile shock absorber 55 squeezes the special-shaped clamping block 572, the special-shaped clamping block 572 drives the cross bar 571 to move, and the cross bar 571 carries The movable plate 566 moves inside the sliding shell 564. Because two strip holes are provided at the bottom of the sliding shell 564 to prevent the connecting gear rack 591 from getting stuck during movement, the movable plate 566 drives the connecting gear rack 591 to move. During the movement of the connecting gear rack 591, it will contact the outer wall of the gear 596, causing the gear 596 to rotate. The gear 596 drives the circular sleeve 593 to rotate, and the circular sleeve 593 drives the stirring rack 595 to rotate. During the rotation of the stirring rack 595, the corrosive liquid inside the working shell 1 is stirred, thereby improving the fluidity of the corrosive liquid and, on the other hand, improving the overall corrosiveness of the corrosive liquid to the bottom end of the automobile shock absorber 55.

[0048] A method for using a corrosion-resistant pressure detection device for an automobile shock absorber comprises the following steps:

[0049] Step 1: Pressure detection;

[0050] Step 2: Stable clamping;

[0051] Step 3: Resilience test;

[0052] Step 4: Corrosion testing.

[0053] When in use, the two ends of the automobile shock absorber 55 are clamped on the inner walls of the two clamping frames 54, and the bottom end of the automobile shock absorber 55 is placed on the top of the sliding bending plate 584. The electric telescopic rod 4 is started, and the electric telescopic rod 4 drives the sliding plate 51 to vertically descend along the outer wall of the fixed column 3. The sliding plate 51 drives the clamping frames 54 to descend, and the clamping frames 54 drive the automobile shock absorber 55 to descend. The reaction force of the sliding bending plate 584 enables the automobile shock absorber 55 to simulate the pressure conditions in actual work. When the sliding plate 51 is descending, the sliding plate 51 will come into contact with the top of the slider 561. The slider 561 is made to descend vertically, and the slider 561 drives the rotating rod 562 to move downward. It is limited by the limiting groove 565, and the rotating rod 562 drives the sliding shell 564 to move along the inner wall of the limiting groove 565. The sliding shell 564 drives the moving plate 566 to move, and the moving plate 566 drives the cross bar 571 to move. The cross bar 571 drives the special-shaped clamping block 572 to move, and the two special-shaped clamping blocks 572 approach each other, thereby clamping the bottom outer wall of the automobile shock absorber 55, preventing the automobile shock absorber 55 from shaking during the pressure detection process, and improving the detection accuracy of the automobile shock absorber 55.

[0054] When the shell of the automobile shock absorber 55 is in the process of descending, the bottom end of the automobile shock absorber 55 can contact the inclined surface of the special-shaped clamping block 572, which can make the special-shaped clamping block 572 drive the cross bar 571 to move slightly, and the cross bar 571 drives the moving plate 566 to move slightly toward the inside of the sliding shell 564. At this time, the two special-shaped clamping blocks 572 can clamp the outer wall of the shell of the automobile shock absorber 55, further improving the stability of the automobile shock absorber 55 during pressure testing, and the sliding shell 564 can drive the L-shaped rod 571 to move slightly. 3 moves, and the L-shaped rod 573 contacts one side of the moving frame 574 during the movement, causing the moving frame 574 to slide along the inner wall of the strip groove 575. The moving frame 574 drives the round rod 577 to move, and the round rod 577 drives the arc plate 578 to move. The two arc plates 578 approach each other and contact the side wall of the special-shaped clamping block 572. Because the special-shaped clamping block 572 is made of flexible material, the special-shaped clamping block 572 is deformed, thereby improving the clamping effect of the special-shaped clamping block 572 on the housing of the automobile shock absorber 55.

[0055] When the two moving frames 574 approach each other, the moving frame 574 drives the rotating bar 582 to move. The rotating bar 582 is limited by the limiting rod 581, and the concave shell 583 slides along the outer wall of the limiting rod 581. The concave shell 583 contacts the top of the sliding bending plate 584 during the movement, squeezing the sliding bending plate 584, so that the sliding bending plate 584 moves horizontally. The sliding bending plate 584 no longer bears the bottom end of the automobile shock absorber 55 during the movement. When the shock absorber 55 is completely out of contact with the top of the sliding bending plate 584, the elastic structure inside the automobile shock absorber 55 causes the bottom end of the automobile shock absorber 55 to move toward the inside of the working shell 1, thereby being able to detect the resilience of the elastic material inside the automobile shock absorber 55, thereby improving the accuracy of the detection. At this time, the clamped automobile shock absorber 55 shell can provide stability for the rebound detection of the automobile shock absorber 55, and prevent the shell of the automobile shock absorber 55 from shaking slightly during the rebound detection of the automobile shock absorber 55.

[0056] When the bottom end of the automobile shock absorber 55 enters the interior of the working shell 1, it will come into contact with the corrosive liquid inside the working shell 1, thereby performing corrosion resistance testing on the automobile shock absorber 55. When the shell of the automobile shock absorber 55 squeezes the special-shaped clamping block 572, the special-shaped clamping block 572 drives the cross bar 571 to move, and the cross bar 571 drives the moving plate 566 to move inside the sliding shell 564. Because there are two strip holes at the bottom of the sliding shell 564 to prevent the connecting gear rack 591 from getting stuck during the movement, the moving plate 566 drives the connecting gear rack 591 to move. During the movement, the connecting gear rack 591 will come into contact with the outer wall of the gear 596, causing the gear 596 to rotate. The gear 596 drives the circular sleeve 593 to rotate, and the circular sleeve 593 drives the stirring rack 595 to rotate. During the rotation of the stirring rack 595, the corrosive liquid inside the working shell 1 is stirred, thereby improving the fluidity of the corrosive liquid and improving the overall corrosiveness of the corrosive liquid to the bottom end of the automobile shock absorber 55.
