Problems solved by technology

In addition, high-strength threaded fasteners are usually produced and used in batches, and the working environment is harsh and harsh. If a traditional wrench or a traditional single-head impact fastening device is used for constant torque tightening, there will be problems during the use of tools. Inconvenient, low work efficiency, and limited range of use

Abstract

The invention relates to an adjustable small-spacing double-head impact fastening device which comprises a first output shaft and a second output shaft, one end of the first output shaft and one end of the second output shaft are each provided with a driving gear, the first output shaft and the second output shaft are arranged in parallel in a spaced mode and connected with respective driving units, each driving unit comprises a power gear, and the two driving gears are meshed with the power gear. The first output shaft and the second output shaft are further connected with an angle adjusting mechanism, the angle adjusting mechanism is used for adjusting the included angle between the centers of the two driving gears and the center of the power gear, the impact fastening device can effectively achieve installation of bolts in various arrangement modes, the impact fastening device is suitable for fastening and detaching the bolts used at small intervals, the output torque of the bolt can be effectively ensured, the working efficiency is improved, and the applicability of the impact fastening device can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of impact fastening devices, in particular to an adjustable small-pitch double-head impact fastening device. Background technique [0002] The impact fastening device is a new type of hand-held electric basis for tightening and dismounting various types of threaded fasteners. It has the significance of realizing the efficient mechanization of small manual assembly and manufacturing. It is widely used in various engineering projects or industries. [0003] In actual production, high-strength bolt links have been widely used. The material and heat treatment process of high-strength bolts are strictly controlled and inspected. Therefore, the torsional shear fracture torque is generally controlled within a relatively accurate range to ensure the reliability of bolted connections. When the tightening torque is too large, if the strength of the threaded fastener is insufficient, it may cause problems such as twi...
