Several classes such as Mn-Zn, Cu-Zn, Ni-Zn, wherein the ferritic yield of Mn-Zn and dosage are maximum, the ferritic resistivity of Mn-Zn
It is low, it is 1~10 ohm/meter, generally in 100kHZ frequency usage below.The ferritic resistivity of Cu-Zn, Ni-Zn is 102
~104 ohm/meters, it is small in the loss of the radio frequency band of 100kHz~10 megahertz, it is mostly used in radio aerial coil, nothing
Line electricity intermediate-frequency transformer.
The base thickness size H of magnetic ferrite magnetic core is critical size, has the portions of client requirement base thickness tolerance standard to be at present
± 0.05mm, but the method for plane is the bottom surface directly with magnetic ferrite magnetic core on tradition grinding magnetic ferrite magnetic core
On the basis of, plane in grinding, rather than on the basis of the bottom surface of base thickness H, be by the base thickness measured value that this is completed the process ±
The requirement of client is not achieved in 0.08mm.
Utility model content
In order to solve technical problem present in above-mentioned background technique, the utility model provides a kind of high fine grinding bottom folder
Tool, the clamp structure is simple, the controllability of attrition process is improved, using the bottom surface of workpiece base thickness H as benchmark grinding work-piece bottom
Plane on thick H, the product standard after processing can reach the requirement of ± 0.05mm.
The technical solution of the utility model is achieved in that
A kind of high fine grinding bottom fixture, it is characterised in that including base portion, 2n support portion, the base portion is a plate,
The 2n support portion is parallel to each other, and is fixedly arranged in the upper plane of base portion, vertical with base portion, the 2n support portion
Upper plane is in the same plane, and parallel with the bottom surface of base portion, 2n-1 card slot is formed among the 2n support portion, often
Spacing between two lateral surfaces of two adjacent support portions is matched with the spacing between two stabilizer blade medial surface of workpiece, and the card slot is wide
Degree is greater than workpiece intermediate cylindrical portion outer diameter, and workpiece is buckled to the plane on the bottom of workpiece and base portion when on support portion in plane
Between there are gap h, gap h is 1~2mm, and the high fine grinding bottom fixture uses iron material matter.
Further, the upper plane of the support portion and the lower plane flatness of base portion are 0.01~0.02mm, bottom
Portions bottom surface is parallel with plane on support portion, and the depth of parallelism is 0.01~0.02mm.
Further, the n is 1~4.
Working principle of the utility model is: being placed with fixture base subordinate's plane on grinding machine workbench, fixture is used
Iron material matter, workbench have magnetism, fixture are firmly adsorbed on workbench, and workpiece is buckled on two support portion of fixture
In plane, base thickness lower plane and the plane on jig support section of workpiece are affixed, the magnetism of workbench remain to by absorption of workpieces in
It on fixture, therefore is the base thickness dimensional tolerance after grinding directly on the basis of workpiece base thickness lower plane when plane on grinding work-piece
It can reach the requirement of ± 0.05mm.It can be buckled to several workpiece on one fixture while being ground, work efficiency is high.
The beneficial effects of the utility model are: structure is simple, the controllability of attrition process is improved, with the bottom of base thickness H
Plane on base thickness H is ground on the basis of face, the product standard after processing can reach the requirement of ± 0.05mm.
