When the test bench detects that the shock absorber specimen is unqualified, the code reading and coating assembly 2 can automatically spray ink to destroy the label on the specimen.

[0065] The working process of this device is:

[0066] Before the test begins, there is no shock absorber specimen on the manual position and the test position. First, the tester installs and places the shock absorber specimen on the manual position. After the specimen is placed, the tester leaves the detection range of the safety light curtain 12 with both hands. Then the tester presses the control button 13 to control the rotation of the turntable. The lifting cylinder 303 lifts upward to clamp the cylinder barrel of the shock absorber specimen. Then the turntable 301 rotates 180°. At this time, the manual position and the test position are interchanged. The piston rod of the servo actuator 9 on the test position drives the upper clamp 7 to move downward for a distance, so that the shock absorber piston rod enters the clamping range of the upper clamp 7. After the upper clamp 7 clamps the shock absorber piston rod, the servo actuator 9 starts to apply load to the shock absorber specimen for testing. After the test is completed, the upper clamp 7 releases the shock absorber piston rod, and the servo actuator 9 piston drives the upper The clamp 7 moves upward to make the shock absorber piston rod leave the clamping range of the upper clamp 7, and the test work on the test position is completed; while a series of test work is carried out on the above-mentioned test position, the tester completes the installation on the manual position and presses the control button 13 to control the rotation of the turntable 301. If the test on the test position has been completed at this time, the turntable 301 will rotate 180° again to complete the position exchange of the two stations. If the test work on the test position has not been completed after the tester presses the control button 13, the test bench will wait until the test work on the test position is completed before rotating; after the turntable 301 completes the second rotation, the test piece that has been tested on the test position is transferred to the manual position, the tester will remove the test piece and install a new piece to be tested, and the test of a shock absorber test piece is completed.

[0067] In addition, if the test bench detects that a test piece is unqualified, after the test piece is transferred from the test position to the manual position, the code reading and coating component 2 will automatically start to destroy the label information on the test piece, and then the tester will take the test piece and put it into the unqualified product area.

[0068] The code reading and coding component 2 includes a code reader and a code sprayer. The code reading and coding component 2 can adjust the height to adapt to different models of vibration damper test pieces.

[0069] The present invention has the following advantages:
