A Pneumatic Expansion Clamping Mechanism

Abstract

The invention discloses a pneumatic expanding and clasping mechanism which comprises a rotary shaft, an outer shaft sleeve, a rear base, a spring protection cover, a wedged shaft sleeve, a spherical pin, a resilient sheet and a guide plate, wherein the rotary shaft is provided with the rear base, the outer shaft sleeve and the spring protection cover; the rear base is fixedly connected with the outer shaft sleeve in a sealed manner; a spring I is arranged between the spring protection cover and the rotary shaft; a spring II is arranged among the rear base, the outer shaft sleeve and the rotary shaft; a clamping spring is arranged on the front end face of the rotary shaft; the clamping spring is connected with the outer shaft sleeve; the wedged shaft sleeve is arranged between the rotary shaft and the outer shaft sleeve; the wedged shaft sleeve is slidingly connected with the outer shaft sleeve in the sealed manner and is connected with the rear base in the sealed manner; the spherical pin is fixedly arranged in a clamping groove of the wedged shaft sleeve; the spherical pin is connected with the resilient sheet; a fast-inserting connector is arranged at the top of the rear base and a guide pin is arranged on the bottom face; and one end of the guide pin is arranged in the guide plate. The pneumatic expanding and clasping mechanism can really simulate the work state of an automobile lock and provides good support for measuring various technical indexes of the lock.

Description

technical field [0001] The invention relates to a clasping mechanism, in particular to a pneumatic expansion clasping mechanism. Background technique [0002] With the improvement of people's living standards, people not only have more and more demand for cars, but also have higher and higher performance requirements for cars. The car lock is one of the main components to evaluate the reliability of the car. In order to meet people's needs, when manufacturing a car, it is usually necessary to rely on the testing mechanism to simulate the rotation of the lock cylinder to different positions after the key is inserted, so as to measure the internal components of the car lock through the torque sensor, pressure sensor and displacement sensor outside the car lock Various data. However, due to factors such as friction and elastic force, the existing testing institutions cannot truly simulate the working state of the car lock, so the support provided for measuring various technic...
