Locking device for threaded fasteners

Abstract

The invention provides a locking device of threaded fasteners. The locking device comprises a grasping mechanism and a tightening shaft; the grasping mechanism is used for grasping the threaded fasteners; the tightening shaft can lock the threaded fasteners grasped by the grasping mechanism in a to-be-mounted part. The tightening shaft comprises a rotating shaft and a motor which is connected with the rotating shaft and drives the rotating shaft to rotate. The output end of the rotating shaft is connected with the grasping mechanism. The locking device of the threaded fasteners is provided with the grasping mechanism for grasping the threaded fasteners; the grasping mechanism is connected with the output end of the tightening shaft, and therefore the threaded fasteners are locked through the tightening shaft; according to the characteristics of the tightening shaft, the threaded fasteners are locked through the tightening shaft, and the threaded fasteners do not need to be manually locked. Compared with the prior art that the threaded fasteners are locked in batches through manual operation, obviously, manual locking is replaced, and manual labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of threaded fastener locking, and more specifically, to a threaded fastener locking device. Background technique [0002] Because threaded connection has the advantages of simple structure, reliable connection, convenient assembly and disassembly, etc., threaded fasteners are widely used. Threaded fasteners mainly include: screws, nuts, bolts, and screws. For example, the fixing of the compressor in the outdoor unit of the air conditioner fixes the compressor on the chassis through nuts and screws on the chassis of the outdoor unit. The commonly used nuts for fixing compressors are hexagonal nuts with washers. At present, the locking of the nut and the stud usually needs to be done manually, and the locking is realized by threading. [0003] At present, it is usually manually grabbing the nut and manually locking the nut. The action flow of the manual locking nut is as follows: the operator grabs the nut ...

AI Technical Summary

Problems solved by technology

[0004] However, the locking nut is manually passed through the air batch, and the locking nut requires a large torque (usually 12N*M) when fixing the compressor, resulting in high labor intensity

[0005] In addition, the compressor usually needs two or more screws and nuts to be fixed. When the nuts are manually tightened, the manual tightening torque is prone to deviation, resulting in poor consistency of the nut tightening torque and affecting the installation quality of the compressor.

[0006] In addition, manual operation of the air batch is used for locking, which leads to low installation efficiency of the compressor. At the same time, the air batch tool will generate a lot of noise during use, resulting in a poor working environment
