Handheld electric thread repairing device

Abstract

The invention discloses a handheld electric thread repairing device. The handheld electric thread repairing device comprises an inner sleeve, an outer sleeve, a circular die and an electric torque wrench, wherein the inner sleeve is connected to the lower end of a main shaft of the electric torque wrench; the outer sleeve is movably connected to the periphery of the inner sleeve and fixedly connected with an outer shell of the electric torque wrench; and the circular die is fixedly connected into an installation hole in the lower end of the inner sleeve. The device can continuously work for a long time like machine tool equipment, is convenient to carry, simple to operate, and suitable for repairing external threads of various specifications, increases the efficiency, and reduces the construction cost at the same time.

Description

technical field [0001] The invention belongs to the technical field of repair tools, and in particular relates to a hand-held electric thread repair device. Background technique [0002] Threaded connection is a very widely used connection form. During installation and use, internal threads or external threads are often damaged, causing threaded fasteners to fail to connect normally. In general, damaged threaded fasteners will be replaced This ensures connection quality. However, in many cases, the damaged threaded fastener cannot be replaced, and at this time, it is necessary to use equipment or manual methods to repair the damaged thread. Repairing detachable screws and nuts with lathes and other equipment is simple and efficient, but for external threads that have been fixed and cannot be disassembled, such as embedded screws, etc., are affected by environmental and working conditions, and cannot be repaired with lathes and other equipment .

AI Technical Summary

Problems solved by technology

However, it is often impossible to replace the damaged threaded fasteners. At this time, it is necessary to use equipment or manual methods to repair the damaged threads.

Repairing detachable screws and nuts with lathes and other equipment is simple and efficient, but for external threads that have been fixed and cannot be disassembled, such as embedded screws, etc., are affected by environmental and working conditions, and cannot be repaired with lathes and other equipment

[0003] At present, manual repair is usually used for fixed external threads. When the number of repairs is small, the cost is low and the operation is convenient. When the number of repairs is large, the efficiency of manual repair is low, especially when repairing threads with specifications above M24. Manual operation is more difficult. Big
