Driving mechanism for electric tool

Abstract

The invention provides a driving mechanism for an electric tool, and belongs to the technical field of electric tools. The problems that an existing electric tool is low in intelligent degree and low in precision are solved. The driving mechanism for the electric tool comprises a motor, a speed reducer and a shell body, wherein a fixing sleeve is arranged between the speed reducer and the shell body, a gear sleeve which is connected with the speed reducer and is in matched transmission with the speed reducer is arranged in the fixing sleeve, and a push rod assembly connected with the electric tool is arranged in the shell body; a lead screw transmission mechanism used for controlling the push rod assembly to operate is arranged between the push rod assembly and the speed reducer, the two ends of the lead screw transmission mechanism stretch into the shell body and the fixing sleeve separately and are connected with the push rod assembly and the gear sleeve separately, and a gear meshed with the gear sleeve and connected with the lead screw transmission mechanism is arranged in the gear sleeve; and the lead screw transmission mechanism is matched with the motor, the speed reducer, the gear sleeve and the gear to convert rotary motion into linear motion, and therefore the push rod assembly is controlled to drive the electric tool to operate. The driving mechanism for the electric tool has the advantages of high intelligent degree and high precision.

Description

technical field [0001] The invention belongs to the technical field of electric tools, and relates to a driving mechanism for electric tools. Background technique [0002] Electric tools, such as crimping pliers, cutters and hydraulic pliers, are necessary tools for wire connection crimping or cutting in the power industry in line infrastructure construction and line maintenance. Generally, it includes a shell, a pliers body and a motor. The pliers body is composed of a fixed pliers and a movable pliers. Cut, so that the caliper body cannot be replaced, and cannot meet the user's requirements. At the same time, after the motor and the housing are assembled, part of its structure is exposed, resulting in an unstable structure after assembly, thereby affecting the operating accuracy. [0003] When in use, the work is generally carried out by manually holding the shell, and its control methods can be divided into manual, hydraulic and electric. Among them, the hydraulic and el...

AI Technical Summary

Problems solved by technology

Generally, it includes a shell, a pliers body and a motor. The pliers body is composed of a fixed pliers and a movable pliers. Cutting, so that the pliers cannot be replaced and cannot meet the user's requirements. At the same time, after the motor and the housing are assembled, part of its structure is exposed, resulting in an unstable structure after assembly, which affects the operating accuracy.

[0003] When in use, the work is generally carried out by manually holding the shell, and its control methods can be divided into manual, hydraulic and electric. Among them, the hydraulic and electric have a low degree of intelligence, and both require manual auxiliary operations, resulting in the control accuracy of which is low when used. There are differences, and it is easy to damage the lines that need to be crimped, thus failing to meet the user's precision requirements
