Electric torque type synchronous bolt fastening device

Abstract

The invention discloses an electric torque synchronous bolt tightener, which comprises a main cylindrical shell, a main groove structure is arranged inside one end surface of the main cylindrical shell, and the other end surface of the main cylindrical shell passes through a bolt A force control mechanism housing is fixed, and a force control mechanism is installed inside the force control mechanism shell, and an end surface of the force control mechanism shell is fixed with a motor fixing shell by bolts, and the inside of the motor fixing shell is An electric motor is installed, and the main shaft of the electric motor in the electric motor passes through the fixed casing of the electric motor and the casing of the strength control mechanism. The present invention utilizes the electric motor to carry out synchronous rotating and fastening effect on multiple bolts, so that multiple bolts can go deep into the fastening part under the action of the thread structure at the same time, thereby reducing the damage to the thread structure and improving the service life of the wheel. In addition, the device has a force control mechanism, which can further protect the thread structure from damage.

Description

Technical field [0001] The invention relates to the technical field of mechanical fasteners, in particular to an electric torque type synchronous bolt fastener. Background technique [0002] At present, in terms of automobile bolt tightening, especially the bolt tightening of automobile wheels, because it is a circular tightening, in the general way, the torque wrench is used for multiple single rotation tightening. However, the biggest disadvantage of a single rotation is that a single rotation causes uneven forces on multiple threaded structures, which will also affect the service life of automobile wheels. Summary of the invention [0003] The purpose of the present invention is to provide an electro-torque-type synchronous bolt fastener to solve the problems raised in the background art. [0004] In order to achieve the above objectives, the present invention provides the following technical solutions: [0005] An electric torque-type synchronous bolt fastener includes a main cy...
