Wheel nut tightening device

Abstract

The invention discloses a wheel nut tightening device which comprises a movable platform and an automatic nut tightening device. The movable platform comprises wheels, a vehicle frame, a rail plate, alifting hydraulic cylinder, a pushing hydraulic cylinder and an installing base plate, the lifting hydraulic cylinder is used for adjusting the height between the rail plate and the vehicle frame, the installing base plate can slide front and back along the rail plate, and the pushing hydraulic cylinder is used for controlling the installing base plate to slide front and back on the rail plate; and the automatic nut tightening device comprises a power device, a first coupling, a dynamic torque transducer, a second coupling and a tightening device, and the tightening device comprises a shell,a transmission shaft, a driving gear, a driven gear and a driven shaft. According to the wheel nut tightening device, dynamic torque transducer is used for achieving dynamic torque monitoring of wheelnuts in the tightening process, accurate control over the wheel nut tightening force is achieved, and meanwhile, the power device is used for driving for quickly and easily complete assembly of the wheel nuts.

Description

technical field [0001] The invention relates to the technical field of automobile maintenance tooling, in particular to a wheel nut tightening device. Background technique [0002] Automobile is used by more and more people as a means of travel, and there are more and more automobile maintenance thereupon. In the maintenance process, the wheels often need to be disassembled for inspection and repair. Ordinary wheels are fixed on the frame by multiple nuts, which need to be installed one by one during assembly. When using manual tools to install, in order to ensure the tightening force of the wheel nuts, usually use longer tools or afterburners. The installation process is time-consuming and laborious. , and the degree of nut tightening depends entirely on personal feeling, the degree of tightening cannot be monitored, and the consistency of the tightening force of multiple nuts cannot be guaranteed; with the advancement of technology, there has been a device for tightening t...
