Abstract
The utility model discloses an improved structure of an electromagnetic fixture, which comprises a central revolving shaft, a working disk and a coil, wherein two ends of the central revolving shaft are respectively sheathed in a spacer bush by a thrust bearing; one end of the spacer bush is provided with a flange; the flange is fixed on a matrix by a bolt; the outer side of the spacer bush is sheathed with a coil shell; one side of the coil shell is provided with an annular baffle; an annular slot is formed by surrounding the annular baffle and the matrix; and a coil is wound in the annular slot to form an electromagnetic passage. After the electromagnetic fixture is improved by the improved structure of the electromagnetic fixture, which is disclosed by the utility model, the central revolving precision is improved, the electromagnetic fixture has a good rigidity, the external diameter precision of a processed part is 0.001-0.002mm, and the processed part is convenient to clamp and regulate. A coreless electromagnetic fixture is added on the original old outer-ring mill, the use range of the original machine tool is enlarged, the versatility is added, and meanwhile, the machine tool use ratio is improved.
Description
Technical field:
The utility model relates to the magnetic holding device of field of machining, is specifically related to a kind of improvement structure of electromagnetism jig.
Background technology:
In field of machining, need to use magnetic holding device usually, and the precision of existing magnetic holding device is not high, also has the inconvenient problem that clamps, the scope of application is restricted.
The utility model content:
The utility model provides a kind of electromagnetism jig to improve structure to the deficiency that existing magnetic holding device exists.
The technical scheme that the utility model adopted: a kind of improvement structure of electromagnetism jig comprises centre rotational axis, scratch diskette; Coil, the two ends of centre rotational axis are set in the spacer through thrust bearing respectively, and an end of spacer is provided with flange; Flange is fixed on the matrix through screw, the wired shell of outside suit of spacer, and a side of this line shell is provided with ring baffle; Ring baffle and matrix surround a cannelure, are wound with coil in this cannelure and form the electromagnetism path.
One end of said centre rotational axis is fixed on through end nut on the inner ring of thrust bearing, and this section of centre rotational axis is equipped with handle.
Scratch diskette is fixed on the other end of centre rotational axis through screw, and that an axle is housed is stifled for pad between the inner ring of this scratch diskette and bearing.
Also be set with an axle sleeve between two side bearings.
The useful good effect of the utility model: after the utility model improved magnetic holding device, the center rotation precision was improved, good rigidly; Compare with original old-fashioned structure and to have the following advantages: the part external diameter precision of (1) processing reaches 0.001～0.002mm, and (2) convenient mounting and clamping is easy to adjust; (3) magnetic holding device is not in the mood in increase on former outer ring mill of haveing been friends in the past; Increase the scope of application of former lathe, increased versatility, also improved machine tool utilization rate simultaneously.
Description of drawings:
Fig. 1 is that the utility model electromagnetism jig improves structural representation.
The specific embodiment:
Referring to Fig. 1, the two ends of the centre rotational axis 2 of this electromagnetism jig are set in the spacer 10 through thrust bearing 4 respectively, also are set with an axle sleeve 5 between two side bearings.One end of spacer 10 is provided with flange; Flange is fixed on the matrix 12 through screw 13, the wired shell 9 of the outside suit of spacer 10, and a side of this line shell 9 is provided with ring baffle; Ring baffle and matrix 12 surround a cannelure, are wound with coil in this cannelure and form the electromagnetism path.One end of said centre rotational axis 2 is fixed on the inner ring of thrust bearing 4 through end nut 3; This section of centre rotational axis 2 is equipped with handle 1; Scratch diskette 8 is fixed on the other end of centre rotational axis 2 through screw 7, and pad is equipped with an axle stifled 6 between the inner ring of this scratch diskette 8 and bearing.
