The hydraulic tensioner resetting device capable of preventing jamming deformation according to claim 5, wherein the notch (38) is formed in the outer wall of the top of the resetting plate (6), the vibration mechanism (39) is arranged on the inner wall of the notch (38), the vibration mechanism (39) comprises an impact block (40) and a spring (41), the spring (41) is connected with the impact block (40) through a bolt, and the spring (41) is fixedly connected with the notch (38).
7. The implementation method of the anti-jamming deformation hydraulic stretcher resetting device according to claim 6, characterized by comprising the following steps:
s1: the hydraulic stretcher is clamped and fixed by the clamping mechanism, the hydraulic stretcher is firstly placed on the clamping mechanism, when the bottom of the hydraulic stretcher is contacted with the base plate, the cushion plate can move downwards due to the gravity of the hydraulic stretcher, the air bag can be compressed when the cushion plate moves downwards, the air in the air bag can be conveyed to the inside of the air cushion through the guide pipe after being compressed, the air cushion can be expanded due to the inflation of the air, at the moment, the expanded air cushion can push the clamping plate to move to one side, the clamping plate can act on the hydraulic stretcher, thereby clamping and fixing the hydraulic stretcher through the clamping plate, when the hydraulic stretcher is reset, the clamping force of the clamping plate on the hydraulic stretcher is increased along with the increase of the pressure along with the gradual increase of the pressure on the hydraulic stretcher, so that the fixing effect of the hydraulic stretcher is improved;
s2: the resetting of the hydraulic stretcher is preprocessed through the pressing mechanism, when the bottom of the hydraulic stretcher is contacted with the clamping mechanism, the support rod moves downwards along with the downward movement of the hydraulic stretcher, at the moment, one side of the connecting plate tilts upwards, the first rack moves upwards along with the tilting of the connecting plate, and the gear is meshed with the first rack, so that the first rack drives the gear to rotate when moving upwards, the gear rotates to drive the second rack to move downwards, at the moment, the pressing plate moves downwards along with the downward movement of the second rack, and the pressing plate is contacted with the top of the hydraulic stretcher, so that the downward movement of the pressing plate can pressurize the top of the hydraulic stretcher;
s3: resetting the hydraulic stretcher, starting a motor, driving a threaded rod to rotate by the motor, driving a reset plate to move downwards by a threaded block along with the rotation of the threaded rod, and resetting the hydraulic stretcher by the reset plate;
s4: carry out vibration processing through vibrating mechanism to hydraulic stretching ware when resetting, when the board that resets moves down under the effect of motor and threaded rod, because the board that resets can produce the vibration in the twinkling of an eye with the contact of hydraulic stretching ware, and the spring can drive the striking piece under the effect of vibration and swing to can improve the vibration range of the board that resets, and then can carry out the processing of resetting to hydraulic stretching ware through the vibration of the board that resets, so that improve the speed of resetting of hydraulic stretching ware.
