Extension length adjusting device in gas spring durability test mechanism

摘要

The present invention relates to a stretch length adjusting device in a durability test mechanism of a gas spring, to install the gas spring to perform a stretching movement by a predetermined value to the durability of the gas spring for testing the durability of the gas spring In the test mechanism, the motor (10) for providing the driving force in the test mechanism, the sleeve (13, 14, 15), which is formed integrally with the motor shaft (11) of the motor (10) and oscillates Limiter switches 50 (50a, 50b, 50c) and the sleeves (13, 14, 15) are installed on the support 60 to drive the motor 10 when the sleeves (13, 14, 15) contact Weights 37, 38 and 39, which are connected to the arms 21, 22 and 23 integrally formed, and installed on the support 27 formed with a screw groove 45, are provided on the weights 37, 38 and 39. Limit switch (40; 40a, 40b, 40c), a plurality of height adjustment to make the motor 10 is stopped driving when contacting The support 27 and the support 27 is provided by a screw part 44 installed on the left and right sides of the support 27 in a shape in which the front slit 43 is formed and penetrating the screw part 44 penetrating the height adjusting slit 43. Left / right support members 41 and 42 that are screwed together, and length adjusting members 24, 25, and 26 for installing the gas springs 34 to the protrusions formed at the lower part and fixed to the arms 21, 22 and 23, respectively. And the support 27 provided with the limit number position 40 for stopping the motor drive is adjustable to the height of the support springs 41 and 42. The durability test of the gas spring, which is adapted to the expansion and contraction length of the gas spring installed in the durability test apparatus, can be performed.
