Description

Electromagnetic sample suction and shooting device of automatic grinding wheel sample grinding machine

Technical Field

The invention relates to an electromagnetic sample sucking and shooting device of an automatic grinding wheel sample grinding machine.

Background

The shape of a furnace front molten iron sample in steel making and iron making of a large-scale steel plant at present is cylindrical or racket-shaped, a direct-reading spectrometer or an X-fluorescence spectrometer is adopted for analysis, the direct-reading spectrometer or the X-fluorescence spectrometer is used for surface analysis, and in order to ensure the accuracy of measurement, the molten iron sample is required to be flat in surface, good in smoothness and uniform in grain. In order to ensure that the surface of the molten iron sample is smooth, has good finish and uniform and consistent grains, sample preparation equipment is required to grind the surface of the molten iron sample. The system appearance equipment of stokehold molten iron sample of large-scale steel plant adopts full-automatic emery wheel sample grinding machine basically, when the molten iron sample was put into to full-automatic emery wheel sample grinding machine anchor clamps bench, in order to ensure safety, must adopt the instrument to put into when putting into the molten iron sample, has two kinds of modes at present, one kind is that the sample is got to the clamp with the iron clamp, then put into full-automatic emery wheel sample grinding machine anchor clamps bench, and this kind of mode defect of getting the sample is: 1. the sample is round, so the sample is easy to fall off in the process of clamping the sample, and 2, the labor intensity is high. The other method is that a magnet sample sucking racket, namely a round racket-shaped mould is manufactured, a round magnet is embedded on the racket-shaped mould, the sample is adsorbed by utilizing the magnetism of the magnet, and then the sample is placed on a clamp table of a full-automatic grinding wheel sample grinding machine. The defects of the mode of clamping the sample are as follows: if the weight of the sample changes, the magnetic force of the magnet is constant, and the sample can not be adsorbed by the magnet, so that the sample falls off; along with the long-time use of magnet, magnetism can weaken, also can not adsorb the sample, causes the sample to drop.

Disclosure of Invention

In order to overcome the functional defects of a special clamp and a magnet sample suction swatter, the invention aims to provide an electromagnetic sample suction swatter device of an automatic grinding wheel sample grinding machine, which adsorbs a sample by utilizing the magnetism generation characteristic of a suction disc type electromagnet after being electrified and can prevent the sample from falling.

The invention adopts the technical scheme that an electromagnetic sample suction and patting device of an automatic grinding wheel sample grinding machine is characterized in that a circular racket-shaped cup body with a handle is made of an aluminum alloy material, wherein the handle is a hollow cylinder with the length L =250mm and the diameter phi =30 mm; the circular racket-shaped cup body is a cylinder with the thickness h =20mm and the diameter phi =36mm, and comprises a cup body, a cup cover and a cavity arranged in the cup body, wherein the bottom of the cup body is provided with a through hole communicated with the cavity, the diameter phi =32mm, and the cup cover is covered on the cup body; placing a circular sucker electromagnet with the thickness h =18mm, the diameter phi =34mm, the DC =18V, the power W =6W, the attraction force =180N and the weight =90g into a circular racket-shaped cup body, connecting a magnetic part of the sucker electromagnet with a through hole at the bottom of the cup body, and the diameter phi =32mm, covering and screwing the cup cover; a rotary RV24 potentiometer with a switch is arranged in the hollow cylindrical handle at a position 23mm away from the front end of the handle, and a rotary switch of the potentiometer is arranged on the surface of the handle; a 18V rechargeable lithium battery is additionally arranged at the tail end of the hollow cylindrical handle; one lead of the sucker electromagnet is connected with a movable terminal in the middle of the potentiometer, and the other lead is connected with the negative electrode of the battery; meanwhile, a switch terminal of the potentiometer is connected with the positive electrode of the lithium battery through a wire, and the potentiometer switch button is rotated to switch on and off the current and adjust the current, so that the electromagnet of the sucking disc is magnetized or demagnetized, the magnetism of the electromagnet of the sucking disc is controlled, the sucking disc electromagnet is enabled to adsorb molten iron samples with different weights, and the molten iron samples are prevented from falling off.

The electromagnet is characterized in that after an iron core is inserted into the energized solenoid, the iron core is magnetized by the magnetic field of the energized solenoid, and the magnetized iron core also becomes a magnet, so that the magnetism of the solenoid is greatly enhanced due to the mutual superposition of the two magnetic fields. The sucker type electromagnet has the function of strong magnetism after being electrified, and can suck, fix or displace an iron heavy object. No magnetism after power failure, convenient and economical use. The other end of the sucker type electromagnet is non-magnetic, and the periphery of the electromagnet is non-magnetic through the magnetic conduction and the shielding of the shell, so that the magnetic force of the magnetic place is strong, and the magnetic force of the place which is not magnetic is very weak. The electromagnetic sample suction device is manufactured by utilizing the characteristics that the electromagnet generates magnetism after being electrified and the strength of the magnetism is changed by the size of current, so that the device can adsorb molten iron samples with different weights, the molten iron samples are prevented from falling off, and the use is convenient and fast.
