Abstract

The present invention relates to the technical field of magnetic core fixing devices, in particular to a magnetic core axial opening fixing device for magnetic core processing. It includes a base, the upper surface of the base is provided with four second chutes in an annular array, the front and rear sides of the base are provided with first movable grooves that communicate with the second chutes, the center of the second screw rod is fixedly connected with a turbine, and the turbine A second thread is symmetrically arranged on both sides, a first positioning slider and a second positioning slider are respectively fixedly connected to the lower surface of the lower fixed guard plate near the edges of both sides of the connecting column, and a screw rod is fixedly connected to the center of the upper surface of the fixing ear. The fixed cover and the fixed seat are provided to realize the fixed clamping of the magnetic core. The fixed cover can be adjusted up and down through the screw rod according to the height of the magnetic core, so that the magnetic cores of different sizes and heights can be fixed. At the same time, the magnetic core is fixed to ensure the stability of the magnetic core during the hole opening process, thereby improving the drilling accuracy of the magnetic core.

Description

technical field [0001] The invention relates to the technical field of magnetic core fixing devices, in particular to a fixing device for axially opening a magnetic core for magnetic core processing. Background technique [0002] The magnetic core is used as the magnetic collecting part of the power sensor or transformer, and its output voltage has a linear relationship with the number of turns of the coil winding. In order to achieve the ideal accuracy of the output voltage, sometimes it is necessary to choose a non-integer multiple of turns for the coil winding, such as choosing one-half turn, three-quarter turn, and so on. In this case, it is necessary to make a hole in the corresponding position of the magnetic core to let the wire pass through it. With the rapid development of intelligent equipment and the improvement of current measurement and control accuracy, as the upstream core component, the demand for the holed magnetic core is increasing.

Problems solved by technology

[0003] When the magnetic core is bored in the axial direction, the magnetic core needs to be fixed, but most of the magnetic cores are cylindrical. When drilling a cylindrical magnetic core, the clamping stability of the magnetic core by the fixing device is poor, so that the opening Deviation occurs, and at the same time, because the height of the magnetic core is not uniform, and the existing fixing device cannot be adjusted according to the height of the magnetic core, the stability when the magnetic core is clamped and fixed cannot be guaranteed. Therefore, the purpose of the present invention is a magnetic core processing The fixing device for the axial opening of the magnetic core is used to solve the poor clamping stability of the fixing device on the magnetic core, which causes deviations in the opening, and the height of the magnetic core is not uniform. The existing fixing device cannot be adjusted according to the height of the magnetic core. The problem of stability when the magnetic core is clamped and fixed cannot be guaranteed
