Screwdriver head assembly capable of achieving automatic butt joint correction and torque fixing

Abstract

The invention discloses a screwdriver head assembly capable of automatically butting, correcting and fixing torque. The screwdriver head assembly comprises a screwdriver head, a spring, a screwdriver head fixing shaft and a screw head sleeve, the screwdriver head comprises a conical part and a sleeve part arranged on the periphery of the conical part in a surrounding mode, a plurality of protruding parts are arranged at the front end of the sleeve part at intervals, a long-strip-shaped hole is formed in the sleeve wall, and a cavity for containing the spring is formed in the tail end of the sleeve part; the screwdriver head fixing shaft is a cylindrical connecting shaft, a mounting groove is formed in the front end of the screwdriver head fixing shaft and used for being inserted into a cavity in the tail end of the screwdriver head to be in butt joint with the spring, and a threaded hole is formed in the middle of the screwdriver head fixing shaft in the radial direction and fixedly connected with the long-strip-shaped hole of the screwdriver head through a limiting screw; the tail end of the screwdriver head fixing shaft is connected with a driving motor; the screw head sleeve comprises a screw head sleeve body, and a plurality of protruding torque rods are arranged at the end of the screw head sleeve body at intervals. According to the method, two-step automatic correction can be realized, and the error-tolerant rate of the docking process is greatly increased.

Description

【Technical field】 [0001] The invention belongs to the technical field of tools, and in particular relates to a screwdriver assembly capable of automatic docking correction and torque fixing. 【Background technique】 [0002] With the rapid development of my country's economy and power grid construction, economic construction and people's lives are increasingly dependent on electricity, and the society's ability to withstand power outages is getting worse. Live work is one of the important means to solve this problem. Live work refers to the operation of testing and repairing high-voltage electrical equipment under the condition of uninterrupted power supply. It is an effective operation to avoid power failure during maintenance and ensure normal power supply. method. The 10kV distribution network is at the end of the power system and is the key link to ensure the continuous supply of power. Its reliability occupies a very important position in the entire power supply system. ...

AI Technical Summary

Problems solved by technology

[0003] 10kV power distribution line work site widely adopts the middle potential work method of insulated bucket arm truck. Operators use original tools to manually complete live work tasks, which require operators to perform manual wiring and untwisting in extremely dangerous environments such as high altitude, high voltage, and strong electromagnetic fields. Operation, high labor intensity, high mental tension, not only brings personal danger to live workers, but also inefficiency in completing operations

[0004] Based on the improvement of the existing technical solutions, there are currently live robot operations, but in the working process of tightening the clamps in the live work of the robots, there are the following problems: 1. The butt joint between the screw head of the motor and the screw head sleeve on the clamp 2. The stroke of the screwdriver head after entering the screw head cover is not easy to match; 3. Additional sleeves are needed on the wire clamp; 4. Special steps are required after tightening the wire clamp. Collect the screw head sleeves used in the operation process; 5. The tightening torque is not easy to control
