Description

Technical Field

[0001] The utility model relates to the technical field of shell detection, in particular to an intelligent shell detection device. Background Art

[0002] Shock absorbers are a crucial automotive component, primarily designed to dampen the rebound oscillations of their elastic structures after shock absorption, as well as impacts from the road. This accelerates the attenuation of frame and body vibrations, improving the vehicle's ride comfort. Shock absorption is achieved by converting and dissipating the kinetic energy of the impact. Some shock absorbers are airtight, with an external housing seal. These sealed shock absorbers require a seal test device to ensure the airtightness of the shock absorber housing to ensure the airtightness of the internal gas.

[0003] In existing technologies, airtightness testing of automotive shock absorber housings is often performed while the shock absorber housing is in a static state, failing to reflect the sealing condition of the shock absorber housing in a dynamic state, resulting in inaccurate test results. Therefore, a new intelligent housing testing device is urgently needed to address this issue. Utility Model Content

[0041] Sliding rod 3, slidably connected to vertical cylinder 2;

[0042] The bottom end of the fixed folding rod 4 is connected to the top end of the sliding rod 3;

[0043] The top of the rotating folding rod 5 is rotatably connected to the top of the fixed folding rod 4;

[0044] A placement plate 6 is connected to the bottom end of the rotating folding rod 5, and the shock absorber housing 11 is placed on the placement plate 6;

[0045] A fixing mechanism, connected to the rotating folding rod 5, for fixing the shock absorber housing 11;

[0046] A deflection and shaking mechanism, one end of which is connected to the base plate 1 and the other end is connected to the sliding rod 3. The deflection and shaking mechanism is connected to the rotating folding rod 5 and is used to drive the shock absorber housing 11 to deflect and shake;

[0047] An air pump 15 is connected to the base plate 1;

[0048] Connect the hose 14, one end of which is connected to the output end of the air pump 15;

[0049] An air intake pipe 12 is connected to the other end of the connecting hose 14 , and the air intake pipe 12 is detachably connected to the shock absorber housing 11 and communicates with the interior thereof;

[0050] The pressure detector 13 is connected to the intake pipe 12 .

[0051] The shock absorber housing 11 is placed on the placement plate 6, and the fixing mechanism fixes the shock absorber housing 11. The air pump 15 sends gas into the shock absorber housing 11, and the pressure detector 13 detects the air pressure inside the shock absorber housing 11, thereby detecting the air tightness of the shock absorber housing 11. Then the deflection and shaking mechanism drives the shock absorber housing 11 to deflect and shake, thereby simulating the movement state of the shock absorber housing 11 during the driving process of the car. After a period of stillness, the pressure detector 13 detects the air pressure inside the shock absorber housing 11 again.

[0052] As an embodiment of the present invention, please refer to Figure 1 and Figure 3 , the fixing mechanism includes:

[0053] The thread groove 7 is provided on the rotating folding rod 5;

[0054] The threaded sleeve 8 is threadedly connected to the thread groove 7;

[0055] The rotating sleeve 9 is rotatably connected to the threaded sleeve 8;

[0056] The limiting folding rod 10 is rotatably connected to the rotating sleeve 9.

[0057] Place the shock absorber housing 11 on the placement plate 6, rotate the threaded sleeve 8, so that the threaded sleeve 8 drives the rotating sleeve 9 to move downward, and the rotating sleeve 9 drives the limiting folding rod 10 to move downward, so that the limiting folding rod 10 abuts against the top of the shock absorber housing 11, and cooperates with the placement plate 6 to fix the shock absorber housing 11.

[0058] As an embodiment of the present invention, please refer to Figure 1 , the deflection and shaking mechanism includes:

[0059] A driving member 16 connected to the base plate 1;

[0060] The missing gear 17 is connected to the output end of the driving member 16;

[0061] The tooth plate 18 is connected to the sliding rod 3 and is located outside the vertical cylinder 2. The tooth plate 18 is engaged with the gear teeth on the missing gear 17;

[0062] The elastic member 19 has a bottom end connected to the bottom plate 1 and a top end connected to the sliding rod 3;

[0063] The deflection assembly has one end connected to the base plate 1 and the other end connected to the rotating folding rod 5, and is used to drive the rotating folding rod 5 to rotate.

[0064] Driving element 16 rotates the missing gear 17. When the teeth on missing gear 17 mesh with tooth plate 18, missing gear 17 drives tooth plate 18 upward. At this point, elastic element 19 elastically deforms. When missing gear 17 rotates to the point where it no longer meshes with tooth plate 18, the reaction force of elastic element 19 causes tooth plate 18 to move downward, thereby driving the rotating folding rod 5 to reciprocate longitudinally. The deflection assembly then drives the rotating folding rod 5 to rotate, thereby simulating the motion of the shock absorber housing 11 during vehicle operation. The elastic element 19 can be a spring, shrapnel, or the like. The driving element 16 can be a stepper motor, servo motor, or the like.

[0065] As an embodiment of the present invention, please refer to Figure 1 , the deflection assembly comprises:

[0066] Gear 20, connected to the rotating folding rod 5;

[0067] The second gear plate 21 is connected to the base plate 1 and meshes with the gear 20 .

[0068] When the fixed folding rod 4 drives the rotating folding rod 5 to vibrate back and forth up and down, the rotating folding rod 5 drives the gear 20 to vibrate back and forth longitudinally. The gear 20 engages with the second tooth plate 21, so that the gear 20 rotates during the longitudinal movement. The gear 20 drives the rotating folding rod 5 to rotate back and forth, and then drives the shock absorber housing 11 to rotate back and forth, thereby simulating the movement state of the shock absorber housing 11 during the driving process of the car, and then performing dynamic detection.

[0069] As an embodiment of the present invention, please refer to Figure 1 A sealing gasket is provided at the connection between the air intake pipe 12 and the shock absorber housing 11.

[0070] The sealing gasket is set to ensure the sealing of the connection to avoid gas leakage.

[0071] The working principle of the present utility model is as follows: the shock absorber housing 11 is placed on the placement plate 6, the threaded sleeve 8 is rotated, so that the threaded sleeve 8 drives the rotating sleeve 9 to move downward, and the rotating sleeve 9 drives the limit folding rod 10 to move downward, so that the limit folding rod 10 abuts against the top of the shock absorber housing 11, and the placement plate 6 is cooperated to fix the shock absorber housing 11, the air pump 15 sends gas into the shock absorber housing 11, the pressure detector 13 detects the air pressure inside the shock absorber housing 11, thereby detecting the air tightness of the shock absorber housing 11, the driving member 16 drives the missing gear 17 to rotate, and when the gear teeth on the missing gear 17 are engaged with the tooth plate 18, the missing gear 17 drives the tooth plate 18 to rotate. When the gear 17 rotates to no longer mesh with the tooth plate 18, the tooth plate 18 moves downward under the reaction force of the elastic member 19, thereby driving the rotating folding rod 5 to move back and forth longitudinally, and the rotating folding rod 5 drives the gear 20 to shake back and forth longitudinally. The gear 20 is engaged with the tooth plate 21, so that the gear 20 rotates during the longitudinal movement, and the gear 20 drives the rotating folding rod 5 to rotate back and forth, thereby driving the shock absorber housing 11 to rotate back and forth, thereby simulating the movement state of the shock absorber housing 11 during the driving process of the car. After a period of rest, the pressure detector 13 detects the air pressure inside the shock absorber housing 11 again.
