Description

Technical Field

[0001] The 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 a general term for all force-transmitting connection devices between the frame and the axle or wheel of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and to buffer the impact force transmitted to the frame or body by the uneven road surface, and to attenuate the vibration caused thereby, so as to ensure that the car can run smoothly. The typical suspension system structure is composed of elastic elements, guide mechanisms and shock absorbers, and some structures also have buffer blocks, lateral stabilizer bars, etc. Elastic elements are in the form of leaf springs, air springs, spiral automobile suspension springs and torsion bar springs. In the automobile suspension, the shock absorber is always used in conjunction with the spring. When we press down a corner of the car body, the spring is actually compressed, and the corresponding swing arm swings at the same time. When the body is released, the body will rebound under the force of the spring. At this time, the shock absorber plays a damping role on the rebound of the spring, that is, it tends to stabilize after rebounding. If there is no shock absorber, the spring will be compressed and rebound again after rebounding, which is manifested as the body tends to stabilize after rebounding many times. Therefore, the shock absorber plays a damping and shock-absorbing role for the spring of the automobile suspension when it rebounds. 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 suspension system. Double-acting cylinder shock absorbers are widely used in cars.

[0003] After the existing automobile shock absorbers are produced, it is necessary to test the pressure value they can withstand. In this process, a device is usually used to press down the automobile shock absorber to test the pressure value that 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.

[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) According to the present invention, when two moving frames approach each other, the moving frame drives the rotating bar to move. The rotating bar drives the concave shell to slide along the outer wall of the limiting rod. During the movement of the concave shell, the top of the sliding bending plate will be contacted to squeeze the sliding bending plate, so that the sliding bending plate moves 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, so that the rebound resilience of the elastic material inside the automobile shock absorber can be detected, 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) In the present invention, both ends of the automobile shock absorber are clamped at the inner walls of the two clamping 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 clamping frame to descend, and the clamping 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 in actual work. When the sliding plate descends, the sliding plate will contact the top of the slider, so that the slider descends vertically. 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) According to 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, so that the special-shaped clamping block 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 detection. In addition, the sliding shell can drive the L-shaped rod to move during the movement. During the movement of the L-shaped rod, it will contact one side of the moving frame, 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 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 the movement. The moving plate drives the connecting gear rack to move, and the connecting gear rack contacts the outer wall of the gear during the movement, causing the gear to rotate. The gear drives the round sleeve to rotate, and the round 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 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 contact the top of the slider 561, so that the slider 561 descends vertically. The slider 561 drives the rotating rod 562 to move downward.

The two arc plates 578 approach each other and come into contact with 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.

[0044] A detection assembly 58 is provided on the side wall of the support plate 2, and the detection assembly 58 includes a limit rod 581 fixedly connected to both ends of one side of the support plate 2, and 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 rotation bars 582 at both ends.

[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 penetrated 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, and 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.

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, the bottom end of the automobile shock absorber 55 is no longer supported. When the automobile 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, so that the resilience of the elastic material inside the automobile shock absorber 55 can be detected, 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, and the stirring assembly 59 includes a connecting tooth frame 591 fixedly connected to the two ends of the bottom of the movable plate 566, and clamping holes 592 are respectively opened around the top of the working shell 1, and 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 fixing rod 594, both ends of the fixing 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 contact with the corrosive liquid inside the working shell 1, so as to perform 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 movable plate 566 moves inside the sliding shell 564. Since two strip holes are provided at the bottom of the sliding shell 564 to prevent the connecting gear frame 591 from getting stuck during movement, the movable plate 566 drives the connecting gear frame 591 to move. During the movement of the connecting gear frame 591, it will contact the outer wall of the gear 596 to make the gear 596 rotate. The gear 596 drives the circular sleeve 593 to rotate. The circular sleeve 593 drives the stirring frame 595 to rotate.

[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 automobile shock absorber 55 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. 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. The rotating rod 562 is limited by the limiting groove 565, and the sliding shell 564 is driven 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 are moved close to each other, thereby clamping the outer wall of the bottom end of the automobile shock absorber 55, preventing the automobile shock absorber 55 from shaking during the pressure detection process, thereby 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, so that the special-shaped clamping block 572 can 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 detection, and the sliding shell 564 can drive the L-shaped rod 571 to move slightly. 3, the L-shaped rod 573 will contact one side of the moving frame 574 during the movement, so that the moving frame 574 slides along the inner wall of the strip groove 575, and the moving frame 574 drives the round rod 577 to move, and the round rod 577 drives the arc plate 578 to move, and 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 drives the concave shell 583 to slide 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, and squeezes the sliding bending plate 584 to make the sliding bending plate 584 move 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 two strip holes are provided at the bottom of the sliding shell 564 to prevent the connecting gear frame 591 from getting stuck during the movement, the moving plate 566 drives the connecting gear frame 591 to move, and the connecting gear frame 591 will come into contact with the outer wall of the gear 596 during the movement, so that the gear 596 rotates, and the gear 596 drives the circular sleeve 593 to rotate, and the circular sleeve 593 drives the stirring frame 595 to rotate. During the rotation of the stirring frame 595, the corrosive liquid inside the working shell 1 is stirred, thereby improving the fluidity of the corrosive liquid and improving the overall erosion of the bottom end of the automobile shock absorber 55 by the corrosive liquid.
