Embodiment Construction

[0024] The present invention will be described in further detail below through specific examples.

[0025] An impact-type electric crimp or cutter, such as Figure 1 to Figure 7 As shown, it includes a housing 9 and a working head for crimping or shearing. A motor 6 and a reducer 5 are installed in the housing 9. The output shaft of the motor 6 is connected to the input shaft of the reducer 5. The output shaft of the reducer 5 drives the working head through the impact rotation assembly 4, the working head includes a sleeve 3, the sleeve 3 includes a sleeve body 31 and a rear cover 32, and the rear cover 32 is installed on the sleeve At the rear end of the barrel 3 , the rear cover 32 is provided with a hole, which is convenient for the output shaft 41 to be inserted and connected with the nut 21 of the lead screw nut mechanism 2 .

[0026] The front end of the sleeve 3 is installed with the jaw assembly 1 ; the rear end of the sleeve 3 is installed in the housing 9 and clamp...

Abstract

The invention discloses impact type electric compression joint or shearing pliers, which comprise a shell and a working head for compression joint or shearing; a motor and a speed reducer are arranged in the shell, the output shaft of the speed reducer drives the working head to move through an impact rotating assembly, the working head comprises a sleeve, and a pliers head assembly is arranged at the front end of the sleeve; and the rear end of the sleeve is arranged in the shell, a lead screw nut mechanism is arranged in the sleeve, the pliers head assembly comprises a pliers arm mounting plate, two mutually matched pliers arms are hinged on the pliers arm mounting plate, the pliers arm mounting plate is arranged at the front end of the sleeve through a central pin, the inner sides of the tails of the two pliers arms are provided with force application bevels, the front end of a lead screw or a nut of the lead screw nut mechanism is provided with a force application part matched with the force application bevels to push the pliers arms to clamp, and the lead screw nut mechanism is connected with the impact rotating assembly. The pliers are powerful and reliable in power, easy and convenient to implement, convenient for replacing various pliers head assemblies and suitable for shearing or clamping of different operations or materials of different specifications.

Description

technical field [0001] The invention relates to a hardware tool, in particular to an impact electric crimping or cutting pliers. Background technique [0002] At present, manual and hydraulic work tools are widely used in pipeline and cable work places such as water supply, power supply, and gas supply. Manual tools are labor-intensive and inefficient, and are basically useless for pipe joints and large-diameter cables. The tool structure of the hydraulic structure is complex, the mechanism is huge and heavy, and requires the cooperation of multiple people, and the hydraulic pipeline and mechanism have fatal defects such as oil leakage, uncleanness, and easy aging and failure. Patent CN201702729U discloses a working head that is connected with an impact wrench and has a clamping or shearing function. The solution is a split structure consisting of an impact wrench and a working head. In actual work, the connection between the working head and the impact wrench is unreliab...
