Inner corner arm jaw assembly for spring dismounting

Abstract

The invention discloses an inner corner arm jaw assembly for spring dismounting. The inner corner arm jaw assembly for spring dismounting comprises a power base located in a first plumb line, a powersliding seat, a fixed base ring located in a second plumb line, a moving sliding ring and an arm jaw assembly installed on the outer sides of the fixed sliding ring and a moving sliding ring; the armjaw assembly comprises multiple driving arm jaws hinged to the outer side of the moving sliding ring and multiple driven arm jaws hinged to the outer side of the fixed base ring; one end, far away from the moving sliding ring, of each driving arm jaw is hinged to one end, far away from the fixed base ring, of the corresponding driven arm jaw; and the outer side surface of each driving arm jaw isprovided with a notch; multiple notches are formed in one plane; and an annular clamping groove for supporting a spring is formed among multiple notches are formed in one plane. For the inner corner arm jaw assembly for spring dismounting, through linkage between the driving arm jaws and the corresponding driven arm jaws, the arranged arm jaw assembly enables the diameter of the annular clamping groove to be increased or decreased according to the use needs so as to be adapted to the sizes of various springs, and the use limitation is avoided.

Description

technical field [0001] The invention relates to the related technical field of electric power tools, in particular to an inner angle arm claw assembly for removing springs. Background technique [0002] The plum blossom contact is a commonly used conductive sliding connection part, which is installed on other handcarts such as switch handcarts, fuse handcarts, and isolation handcarts. The plum blossom contact includes plum blossom contact fingers, contact finger grids and mounted on Among the four springs of the plum blossom contact finger, the spring close to the conductive arm is the inner spring, and the one farther away from the conductive arm is the outer spring. Whether the pressure of the inner and outer springs is normal during use is directly related to the safe operation of the power equipment. The plum-blossom contacts are divided into different specifications according to their rated conduction current value. The number of contacts and the size of each part of th...

Problems solved by technology

[0005] 1. The replacement tools in the prior art are generally fixed in size, so that they can only be removed for one size of spring, which is not universal;

[0006] 2. The replacement tools in the prior art generally lift the spring from the inner side of the spring by claw hands. This method is suitable for the spring on the outer side of the plum blossom contact, but the spring on the inner side of the plum blossom contact cannot be replaced. limitation;

[0007] 3. In the replacement tool in the prior art, when the general gripper grabs the spring, there is instability. Due to the elastic coefficient of the spring itself, if the spring is not grasped well, the spring will fall off from the gripper, which is dangerous , so we propose a kind of inner curved arm claw assembly for spring removal to solve the above problems
