Abstract

The invention provides a bolt tightening device, and belongs to the field of mechanical equipment. The bolt tightening device comprises an oil supply mechanism, an electric pump, a control mechanism and a force application mechanism, wherein the oil supply mechanism comprises an oil tank, the electric pump is located on the oil tank, and an oil inlet of the electric pump communicates with the oiltank; the control mechanism comprises a proportional reversing valve, the proportional reversing valve is located on the oil tank, an oil inlet of the proportional reversing valve communicates with anoil outlet of the electric pump, and an oil outlet of the proportional reversing valve communicates with the oil tank; and the force application mechanism comprises a working head and a sleeve, a first oil port of the working head communicates with a first working oil port of the proportional reversing valve, a second oil port of the working head communicates with a second working oil port of theproportional reversing valve, the sleeve is detachably inserted in the working head, and the working head is used for driving the sleeve to rotate. By means of the bolt tightening device, rotating torques in different directions can be output in a high-precision mode so as to tighten a bolt.

Description

technical field [0001] The disclosure belongs to the field of mechanical equipment, in particular to a bolt tightening device. Background technique [0002] With the progress of society and the development of science and technology, the assembly accuracy and assembly reliability of parts in the industrial production process are also required to be higher and higher. For example, in some assembly processes, it is necessary to apply tightening torque to the bolts, and it is necessary to control the accuracy of the torque in real time when tightening the bolts to ensure the smooth implementation of the bolt assembly. [0003] In the related art, the operation mode adopted when applying the tightening torque to the bolts is usually to use a manual hoist to pull the wrench through the manual hoist to tighten the bolts. [0004] However, the construction efficiency of the manual hoist is low, and the pulling force can only rely on the visual inspection of the operator, and the er...
