Abstract

The invention relates to the technical field of assembling, in particular to a tightening and lengthening transition mechanism. The tightening and lengthening transition mechanism comprises a tightening device and a tightening shaft on the tightening device. The tightening and lengthening transition mechanism further comprises a sleeve, a transition sleeve and a counter force transition sleeve, wherein the sleeve is used for assembling a fastener, one end of the transition sleeve is fixedly connected with the sleeve, the other end of the transition sleeve is fixedly connected with the tightening shaft, the counter force transition sleeve is arranged outside the sleeve and the transition sleeve, one end of the counter force transition sleeve is connected with the tightening device, and a counter force block is arranged above the other end of the counter force transition sleeve. The tightening and lengthening transition mechanism is small in size, low in weight, simple in structure, convenient to maintain, safe and reliable, the fastener is conveniently and accurately assembled, and use by an operator is protected and is convenient.

Description

technical field [0001] The invention relates to the field of assembly technology. Specifically, the present invention relates to a tightening and lengthening transition mechanism, in particular to a mechanism capable of realizing linear tightening control torque required in a narrow space. Background technique [0002] The front axle is an important assembly on a car, mainly including steering knuckles, steering kingpins, front beams and other components. The front axle is connected to the frame through the suspension. In addition to bearing the vertical load between the ground and the frame, it also bears the braking force, lateral force and the moment formed by these forces, and ensures the correct movement of the steering wheel. The axle is connected to the frame through the suspension, supports most of the weight of the car, and transmits the traction or braking force of the wheels, as well as the lateral force to the frame through the suspension. [0003] In the use o...
