Abstract

The invention relates to the technical field of bolt tightening, in particular to a bolt tightening device, a bolt loosening device and a multi-bolt tightening and loosening device and aims at solving the problems that tightening and loosening of studs or total-thread bolts in the prior art are large in labor intensity, low in working efficiency and low in technical content due to the fact that no special tool exists for clamping threads of the bolts or sleeves cannot be rapidly taken down after the bolts are clamped through the thread sleeves. According to the rapid stud tightening device, the principles of coaxial decentration, blocking conical surface clamping, centrifugal force, friction force and the like are applied, the threads of the studs can be accurately and rapidly clamped for tightening or loosening, the equipment can be rapidly taken down after the studs are tightened or loosened, and the working efficiency can be greatly improved when the device is used inn cooperation with a high-speed electric or pneumatic impact wrench.

Description

technical field [0001] The invention relates to the technical field of bolt screwing, in particular to the technical field of a bolt tightener, a bolt loosener and a multi-bolt tightener and loosener. Background technique [0002] The ever-increasing labor cost is a problem that every enterprise has to face in the process of survival and development. Every enterprise is racking their brains to improve production efficiency and industrial automation in order to improve market competitiveness. Assembly and maintenance is an important process in mechanical automation, and the screwing of bolts is an essential process for mechanical assembly and maintenance. Its efficiency directly affects the production efficiency and quality of products, and also directly affects the profit and survival of enterprises. However, most of the conventional bolt screwing procedures of general enterprises are screwed by high-efficiency electric wrench, pneumatic wrench, hydraulic wrench and other ...
