Small-size precise torque tightening unit

Abstract

The invention discloses a small-size precise torque tightening unit, which belongs to the technical field of automatic precise tightening equipment and comprises a motor, a speed reducer, a bevel gear set and a tightening sleeve. Wherein the motor is connected with the speed reducer, the motor provides power, torque is enhanced through the speed reducer, then the power is transmitted to the bevel gear set, and the bevel gear set drives the tightening sleeve to act; the bevel gear set converts horizontal motion into vertical rotary motion. The tightening unit is mainly applied to an accurate tightening device in a narrow space environment, tightening torque can be measured in real time in a closed loop mode, the rotating angle output by a tightening sleeve can be accurately measured, visual monitoring of the tightening process in a closed inner cavity environment can be provided, all functions are integrated in a tightening mechanism and on the surface of a shell, and the structure is compact.

Description

technical field [0001] The invention relates to the technical field of precise torque tightening devices, in particular to a small-sized precise torque tightening unit. Background technique [0002] In the connection of engine assemblies and components, the tightening torque in the main connecting parts is strictly specified in each assembly component. For a large operating space, standard torque tightening units are generally used for torque tightening. The large-scale application of torque tightening units is an important way to achieve "mechanical replacement" and promote the transformation and upgrading of traditional manufacturing technologies. [0003] However, for torque tightening in many small spaces, since the standard torque tightening unit occupies a relatively large volume, it cannot be arranged in a narrow space. The existing tightening equipment mostly detects the output torque value in an open loop. Due to the limitation of the working space, it is necessary ...
