[0003] Since CDC shock absorbers play a key role in the driving process of a car, their durability and reliability are directly related to the overall performance and safety of the vehicle.

At this time, the telescopic end of the started second electric push rod 209 will move, driving the single-port sleeve 210, the return spring 211, the moving rod 212, the limit ring 213, the mounting bracket 214, the electromagnet 215 and the other clamping plate 207 to move. When the other When one clamping plate 207 contacts one of the clamping plates 207 and the other clamping plate 207 can no longer move, the CDC shock absorber body 3 to be tested can be fixed, and the surface of the limiting ring 213 just contacts the surface of the single hole block 206. At this time, the controller 107 will pause the second electric push rod 209 and then start the first electric push rod 205. The first electric push rod 205 that is started will drive the slider 204 to move horizontally with the cooperation of the stabilizing frame 201, the placing table 202 and the slide 203. Then the moving slider 204 will drive the fixed CDC shock absorber body 3 to move with the cooperation of the connecting plate 216 and the connecting frame 208. When the slider 204 moves to a point where it can no longer move, the controller 107 will The first electric push rod 205 is paused. At this time, the bottom end of the CDC shock absorber body 3 just moves to the top groove of the fixing seat 131. At the same time, one end of the pin is just aligned with the socket on the fixing seat 131. Then the telescopic end of the second electric push rod 209 activated by the controller 107 will continue to drive the single-port sleeve 210 to move. At the same time, the moving single-port sleeve 210 will continue to drive the pin fixed to the magnetic end of the electromagnet 215 to move. At the same time, the moving single-port sleeve 210 will also cooperate with the limiting ring 213, the single-hole block 206 and the moving rod 212 to compress the return spring 211 inside the single-port sleeve 210. When one end of the pin moves to the fixing seat 131, the CDC shock absorber body 3 can be fixed in the fixing seat. The first electric push rod 205 is on the seat 131 and does not move. Then the controller 107 turns off the electromagnet 215 and starts the clamp 126 (in the initial state, the clamping end of the clamp 126 is in the open state) to fix it. Then, the controller 107, the second electric push rod 209, the return spring 211 and the previous linkage components are used to make the electromagnet 215 and the other clamping plate 207 reset and move back to their original positions. Then, the controller 107, the first electric push rod 205 and the previous linkage components are used to reset the slider 204 and the connecting frame 208 to their original positions. When the CDC shock absorber body 3 completes the test operation, the above-mentioned operation steps are repeated to allow the two clamping plates 207 to clamp the CDC shock absorber body 3 after the test.The clamp 126 is then released from the CDC shock absorber body 3. The mounting bracket 214 is then moved, allowing the magnetic end of the electromagnet 215 to contact the surface of the latch. The electromagnet 215 is then energized to attract the latch. The mounting bracket 214 is then returned to its original position, removing the latch from the fixing seat 131. The slider 204 is then returned to its original position, and the clamped CDC shock absorber body 3 is removed from the fixing seat 131. Once the slider 204 has returned to its original position, the two clamping plates 207 are separated, and the CDC shock absorber body 3 after the test is removed from between the two clamping plates 207.

[0056] The effect and working principle of the entire mechanism are as follows:

[0057] In the preparation stage, first connect the distribution box 102, keyboard 104, rewinding and unwinding device 105, display 106, controller 107, two first electric cylinders 108, two control buttons 110, second electric cylinder 115, vibration device 117, fixer 118, clamp 126, lifting device 127, alarm 130, first electric push rod 205, second electric push rod 209 and electromagnet 215 in accordance with relevant electrical safety standards and specifications. Then turn on the controller 107, and set various parameters of the two first electric cylinders 108, second electric cylinder 115, first electric push rod 205, second electric push rod 209, vibration device 117, fixer 118, clamp 126, lifting device 127, alarm 130 and electromagnet 215 through the cooperation of keyboard 104 and display 106.

[0058] During the loading stage, when the CDC shock absorber body 3 needs to be subjected to a durability reliability test, the bottom end of the CDC shock absorber body 3 is first moved between the grooves of the two clamping plates 207, and the angle and position are adjusted. The electromagnet 215 is then activated by the controller 107 to generate magnetic force at its magnetic end. The pin for fixing the CDC shock absorber body 3 is then magnetically fixed to the magnetic end of the electromagnet 215. The second electric push rod 209 is then activated by the controller 107. The telescopic end of the activated second electric push rod 209 moves, driving the single-port sleeve 210, the return spring 211, the moving rod 212, the limiting ring 213, the mounting bracket 214, the electromagnet 215 and Another clamping plate 207 moves. When the other clamping plate 207 contacts one of the clamping plates 207 and the other clamping plate 207 can no longer move, the CDC shock absorber body 3 to be tested can be fixed. At the same time, the surface of the limit ring 213 just contacts the surface of the single hole block 206. At this time, the controller 107 will pause the second electric push rod 209 and then start the first electric push rod 205. The first electric push rod 205 that is subsequently started will drive the slider 204 to move horizontally under the cooperation of the stabilizing frame 201, the placement table 202 and the slide 203. Then the moving slider 204 will drive the fixed CDC shock absorber body 3 under the cooperation of the connecting plate 216 and the connecting frame 208. When the slider 204 moves to a point where it cannot move, the controller 107 will pause the first electric push rod 205. At this time, the bottom end of the CDC shock absorber body 3 just moves to the top groove of the fixing seat 131, and one end of the pin just aligns with the socket on the fixing seat 131. Then the telescopic end of the second electric push rod 209 activated by the controller 107 will continue to drive the single-port sleeve 210 to move. At the same time, the moving single-port sleeve 210 will also continue to drive the pin fixed to the magnetic end of the electromagnet 215 to move. At the same time, the moving single-port sleeve 210 will also cooperate with the limiting ring 213, the single-hole block 206 and the moving rod 212 to make the return spring 211 inside the single-port sleeve 210 When one end of the latch moves to the fixing seat 131, the CDC shock absorber body 3 can be fixed on the fixing seat 131 and cannot move. Then the controller 107 turns off the electromagnet 215 and starts the clamp 126 (in the initial state, the clamping end of the clamp 126 is in the open state) to fix it. Then, the controller 107, the second electric push rod 209, the return spring 211 and the previous linkage components are used to make the electromagnet 215 and the other clamping plate 207 return to their original positions. Then, the controller 107, the first electric push rod 205 and the previous linkage components are used to return the slider 204 and the connecting frame 208 to their original positions.

[0059] During the test phase, when the CDC shock absorber body 3 is clamped and fixed on the fixing seat 131, the handle 124 is first used to drive the screw of the ball screw 123 to rotate. At this time, the rotating screw will drive one group of another perforated plates 119 to move upward under the cooperation of the nut on the ball screw 123, the other two long rods 112, one group of one perforated plates 119 and the six second auxiliary rings 120. Then, the moving group of another perforated plates 119 will drive the fixer 118, the two spring bodies 121 and the limiter 125 to move at the same time. When the fixer 118 moves to a point where it cannot move, the handle 124 is stopped from rotating. At this time, the two clamping ends of the fixer 118 are just at the same horizontal plane. Then, one of the control buttons 1 is pressed. 10, the controller 107 will start the fixture 118, and the two clamping ends of the fixture 118 will move toward each other. When the two clamping ends of the fixture 118 are in contact with each other, the top of the CDC shock absorber body 3 is just blocked. Then the controller 107 is used to start the lifting device 127. The lifting device 127 will be driven by the other two long rods 112 and the corresponding two second auxiliary rings 120. The cooperation of the two long rods 112 and the corresponding two second auxiliary rings 120 drives one of the groups of perforated plates 119 and the clamp 126 to move up at the same time. Then, one of the groups of perforated plates 119 will move up at the same time. With the cooperation of 118, the two spring bodies 121 are compressed, and at the same time, one of the perforated plates 119 in one group that moves upward will perform a compression durability reliability test on the CDC shock absorber body 3 with the cooperation of the clamper 126. When the CDC shock absorber body 3 completes the compression durability reliability test operation, the previously moving parts are directly reset to their original positions, and then the off switch of one of the control buttons 110 is pressed. When it is necessary to perform a tilt durability reliability test on the CDC shock absorber body 3, the reel for winding the wire rope is first installed on the reeling device 105, and then one end of the wire rope is fixed to the top of the CDC shock absorber body 3, and then the start switch of the reeling device 105 is pressed. At this time, the reeling device is started 105 will perform the wire rope reeling operation, and the reeled wire rope can be used to perform the tensile tilt durability reliability test on the CDC shock absorber body 3. When the CDC shock absorber body 3 completes the test, the wire rope is unwound by the reeling and unwinding device 105, and then one end of the wire rope is removed from the CDC shock absorber body 3. Then the reeling and unwinding device 105 is closed. When it is necessary to perform the vibration durability reliability test on the CDC shock absorber body 3, the start switch on one of the control buttons 110 is first used. At this time, the controller 107 will simultaneously start the two first electric cylinders 108, and then the two started first electric cylinders 108 will drive the protective frame 109 to move downward together until the protective frame 109 moves to the front of the CDC shock absorber body 3.Then the controller 107 will simultaneously pause the two first electric cylinders 108 and start the second electric cylinder 115. At this time, the started second electric cylinder 115 will drive the vibration device 117 and the auxiliary device 128 to move under the cooperation of the connecting rod 114, the other two long rods 112 and all the perforated blocks 132. When the vibration end of the vibration device 117 contacts the top of the CDC shock absorber body 3, the controller 107 will pause the second electric cylinder 115. At this time, the top of the CDC shock absorber body 3 is just sleeved inside the limiting ring of the auxiliary device 128. Then the controller 107 will start the vibration device 117. The started vibration device 117 can perform a vibration test operation on the CDC shock absorber body 3 to measure its durability and reliability. When the CDC shock absorber body 3 completes the vibration test, the previously moving parts are reset, and then the off switch of one of the control buttons 110 is pressed;

[0060] In the blanking stage, when the CDC shock absorber body 3 after the test needs to be blanked, the above steps are repeated at this time, and the two clamps 207 are used to clamp the CDC shock absorber body 3 after the test. Then, the clamp 126 is released from the CDC shock absorber body 3, and the mounting frame 214 is moved to allow the magnetic end of the electromagnet 215 to contact the surface of the latch, and the electromagnet 215 is energized to attract the latch. Then, the mounting frame 214 is reset to its original position, that is, the latch is removed from the fixing seat 131, and then the slider 204 is reset to its original position, and the clamped CDC shock absorber body 3 is removed from the fixing seat 131. When the slider 204 is reset to its original position, the two clamps 207 are separated, and then the CDC shock absorber body 3 after the test is removed from between the two clamps 207.

[0061] Among them, when the internal components of the CDC shock absorber durability reliability test equipment fail, the controller 107 will send an alarm prompt to the alarm 130. When the staff knows the alarm prompt, they can directly press another control button 110 to perform an emergency stop.

[0062] Among them, the distribution box 102, the keyboard 104, the reeling and winding device 105, the display 106 (which can display the compression, tilt and vibration durability reliability test of the CDC shock absorber body 3), the controller 107, the first electric cylinder 108, the control button 110, the second electric cylinder 115, the excitation device 117, the fixer 118, the ball screw 123, the limiter 125, the clamp 126, the lifting device 127, the auxiliary device 128, the alarm 130, the first electric push rod 205, the second electric push rod 209 and the electromagnet 215 are all existing technologies, and their models can be selected according to actual conditions, so no excessive explanation is given here.
