A ball type torsion clutch electric tool

Abstract

The invention provides a ball type torsion clutch type electric tool. The ball type torsion clutch type electric tool comprises a handheld shell body of the electric tool, a speed changer and an adapter flange. The speed changer and the adapter flange are arranged in the handheld shell body and are sequentially connected with a drive motor. The adapter flange is connected with a transmission clutch ring. The transmission clutch ring is in a plum blossom hole inner ring and is provided with a steel ball. A rotating shaft with an end provided with a quick-release chuck is arranged in the adapter flange and the transmission clutch ring through bearings. A pressure block and a pressure spring are sequentially arranged from the end face of a shaft flange, with a groove, of the rotating shaft. An adjusting nut with an end face provided with a bevel gear and a jacking block arranged on a stepped shaft of the right end of the adjusting nut in a sleeved mode are arranged on the middle section, with adjusting threads and a guide groove, of the rotating shaft. The output section of the rotating shaft is fixed to the front end port of the handheld shell body through a bearing and a bearing seat. Through a clutch device composed of the transmission clutch, the steel ball, the pressure block, the pressure spring, the adjusting nut and the jacking block, the ball type torsion clutch type electric tool can adjust tool locking tension in a stepless mode, meets requirements of electric tools for different kinds of torsion, and brings convenience to production line assembling.

Description

technical field [0001] The invention belongs to the technical field of electric hardware tools, and relates to a torque electric tool, in particular to a ball type torque clutch electric tool. Background technique [0002] Electric tools are often used in the existing electronic processing and machinery manufacturing industries, especially in the assembly line, in order to ensure efficient and fast product assembly, they are often used with torque stepless adjustment settings, torque clutch overload separation and automatic engagement The electric screwdriver or electric wrench with reset function, the existing electric screwdriver or electric wrench adopts 3 technologies respectively: [0003] 1. The torque stepless adjustment of the common electric screwdriver or electric wrench is manually rotating the adjusting nut, relying on 3 or 4 3mm ejector pins to press the push block compression spring to obtain the elastic force, the structure is poorly matched, and the load forc...

AI Technical Summary

Problems solved by technology

[0003] 1. The torque stepless adjustment of the common electric screwdriver or electric wrench is manually rotating the adjusting nut, relying on 3 or 4 3mm ejector pins to press the push block compression spring to obtain the elastic force, the structure is poorly matched, and the load force is low, such as Qili Speed ​​SKD100L; when the torque is close to 10N.m, it is difficult to manually rotate the adjusting nut, and the adjusted load is unreliable, so the failure rate is high

[0004] 2. If the torque of DEVON 5219.2 impact wrench is fixed and cannot be adjusted

[0005] 3. For example, DEVON 5241 rechargeable electric drill, although it is equipped with torque adjustment, it cannot realize stepless gear adjustment and cannot meet the use requirements.
