In the radius of moving magnet core.
Further, the side of truncated cone-shaped magnetic core and its axis direction have 7 ± 2 ° of angle.
Further, the height of truncated cone-shaped magnetic core is 6 ± 0.5mm.
Further, fixed guide sleeve is arranged with outside mobile column.
Further, reset spring is equipped in guide sleeve.
Further, the utility model also provides a kind of piano type abrasive finishing pad, and piano type abrasive finishing pad includes several is arranged successively
Key, key includes proportion electro-magnet and briquetting interconnected, and proportion electro-magnet is aforementioned proportion electromagnet.
The beneficial effects of the utility model are:
(1) proportion electro-magnet of the utility model, in use, being powered to coil generates magnetic field, moving magnet core is in magnetic field
Middle movement under force, and mobile column is driven to move out, output pressure is equipped with truncated cone-shaped magnet between moving magnet core and mobile column
Core, the radius of one end that truncated cone-shaped magnetic core is connect with moving magnet core are greater than the radius of its other end, truncated cone-shaped magnetic core with
The radius of one end of moving magnet core connection is less than the radius of moving magnet core, needing by the way that truncated cone-shaped magnetic core is arranged
Stroke in output pressure pressure difference it is smaller, i.e., proportion electro-magnet reality output pressure and need between output pressure deviation compared with
It is small, so that the proportion electro-magnet of the utility model has the beneficial effect that control precision is high and control is easy, in conjunction with above-mentioned
Beneficial effect can use for a long time when the proportion electro-magnet of the utility model is used for piano type abrasive finishing pad, solve the prior art
The problem of output pressure can not be precisely controlled after middle cylinder long-time use.
(2) side of truncated cone-shaped magnetic core and its axis direction have 7 ± 2 ° of angle so that in beneficial effect (1)
The pressure difference of output pressure is smaller in the stroke needed is advanced optimized；The height of truncated cone-shaped magnetic core is 6 ± 0.5mm,
So that the stroke that the proportion electro-magnet of the utility model exports meets the requirement of piano type abrasive finishing pad.
(3) it is arranged with fixed guide sleeve outside mobile column, so that mobile column is more stable when moving out, is not in
The problem of column shakes is moved, so that the pressure of output is more stable, and then when being used for piano type abrasive finishing pad, so that piano type
The sanding effect of abrasive finishing pad is more preferable, and reset spring is equipped in guide sleeve, after the completion of use, under the action of reset spring, and magnetic
Iron core drives mobile column to automatically reset.
(4) the piano type abrasive finishing pad of the utility model, including several keys being arranged successively, key includes interconnected
Proportion electro-magnet and briquetting, when sanding, plate passes through under piano type abrasive finishing pad, specifically, when thering is plate to pass through under key,
Key is pressed downward carrying out plate sanding, i.e., the proportion electro-magnet in the key pushes briquetting pushing pair to briquetting output pressure
Plate carries out sanding, and when not having plate to pass through under key, key is failure to actuate, in conjunction with beneficial effect (1)~(3), use ratio
Electromagnet controls precision height as dynamical element, and control is easy, and only need to be powered to powering off to coil can be completed control, Zai Yifang
Face, proportion electro-magnet have the advantages that stability is high, to sum up, so that the piano type abrasive finishing pad of the utility model is used in long-time
After remain to that there is preferable sanding effect.
