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

The invention relates to a double-end adjustable impact fastening device. The double-end adjustable impact fastening device comprises a first output shaft and a second output shaft, the first output shaft and the second output shaft are arranged in parallel at intervals and connected with a center driving shaft, the center driving shaft drives the first output shaft and the second output shaft to rotate synchronously, one end of the first output shaft and one end of the second output shaft form the impact fastening device, an angle adjusting mechanism is arranged between the first output shaft and the center driving shaft and between the second output shaft and the center driving shaft, the angle adjusting mechanism is used for adjusting the included angle between the connecting line of the center of the first output shaft and the center of the center driving shaft and the connecting line of the center of the second output shaft and the center of the center driving shaft, the double-end impact fastening device is capable of effectively achieving installation of bolts in various arrangement modes, suitable for fastening and detaching the bolts used at small intervals, capable of effectively ensuring the output torque of the bolts, capable of improving the working efficiency and capable of effectively improving the applicability of the impact fastening device.
Description
technical field [0001] The invention relates to the technical field of impact fastening devices, in particular to a double-head adjustable 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 of high-strength bolts and its heat treatment process are strictly controlled and inspected. Therefore, its torsional shear fracture moment is generally controlled within a relatively accurate specified range, thereby ensuring 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 s...
