Abstract
The utility model discloses a kind of dynamic iron core press-fit structure, comprise dynamic iron core body and plastic seal, dynamic iron core body end has the counterbore for installing described plastic seal, be provided with some spaced apart annular boss in counterbore, counterbore inner wall of end edge is provided with the hypotenuse chamfering of a ring shape.The utility model changes the structure that original dynamic iron core inwardly closes up at one end endoporus oral area increases some boss, produce axial force, seal is made firmly to be connected on dynamic iron core, avoid because tightening force radial when original structure closes up is wayward, efficiently solve the problem because the excessive generation distortion of radial tightening force and the too small generation of radial tightening force come off.
Description
Technical field
The utility model relates to a kind of electromagnetically operated valve parts, particularly electromagnetic relay parts, is specifically related to a kind of dynamic iron core press-fit structure.
Background technology
At present, electromagnetic relay has been widely used in household electrical appliance, automobile and other industries, along with the development of technology, its kind also gets more and more, most important parts in electromagnetic relay-dynamic core assembly is often kind of requisite parts of electromagnetic relay, is assembly plastic seal and dynamic iron core being press-fitted rear formation during manufacture, existing dynamic iron core press-fit structure is generally the inside tightening structure of oral area, because dynamic iron core and plastic seal are all thin-wall parts, when plastic seal is press-fitted in dynamic iron core, because radial load adduction makes iron core occur outer rising, cause operationally there is the risk of clamping stagnation in winding assembly, and the active force of six of plastic seal air vent holes also easily because inwardly tightening up produces distortion, affect properties of product, in addition due to the more difficult control of radial tightening force size, power is excessive yielding, too small, two parts easily produce and come off, be press-fitted difficulty larger, not only percent defective is high, and poor reliability.
Utility model content
The utility model aims to provide a kind of dynamic iron core press-fit structure, with solve clamping stagnation in existing electromagnetic relay existing for dynamic core assembly in winding assembly, yielding, assembly quality is unstable, be press-fitted that difficulty is large, percent defective is high and the problem of poor reliability.
The utility model is achieved by following technical solution:
A kind of dynamic iron core press-fit structure, comprise dynamic iron core body and plastic seal, described dynamic iron core body end has the counterbore for installing described plastic seal, is provided with some spaced apart annular boss in counterbore, and described counterbore inner wall of end edge is provided with the hypotenuse chamfering of a ring shape.
The cross section of described annular boss is triangle, and its side near described chamfer bevel is inclination shape, and opposite side is vertical with dynamic iron core inner body wall, and is fillet in the middle part of annular boss.
The outer wall of described annular boss and plastic seal is interference fit.
Described interference fit is of a size of 0.25-0.45mm.
The beneficial effects of the utility model are:
Compared with prior art, the dynamic iron core press-fit structure that the utility model provides, change the structure that original dynamic iron core inwardly closes up at one end endoporus oral area and increase some boss, produce axial force, seal is made firmly to be connected on dynamic iron core, avoid because tightening force radial when original structure closes up is wayward, efficiently solve the problem because the excessive generation distortion of radial tightening force and the too small generation of radial tightening force come off, not only reduce percent defective and labor intensity of operating staff, make seal more can firmly be connected on dynamic iron core simultaneously, add the reliability that parts connect, in addition, by improving dynamic core structure, quality is press-fitted in raising, the production efficiency of 3 times is improve while reducing product loss due to spoiled work 30-40%, the reliability connected due to parts increases, and product dependability is protected, and makes product economy benefit improve 30-40%.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is dynamic iron core body partial sectional view in the utility model;
In figure: 1-moves iron core body, 2-plastic seal, 11-annular boss, 12-hypotenuse chamfering, 21-outer wall.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in required protection range is not limited to;
As shown in Figure 1-2, the dynamic iron core press-fit structure that the utility model provides, comprise dynamic iron core body 1 and plastic seal 2, described dynamic iron core body 1 end has the counterbore for installing described plastic seal 2, be provided with some spaced apart annular boss 11 in counterbore, described counterbore inner wall of end edge is provided with the hypotenuse chamfering 12 of a ring shape.Change the structure that original dynamic iron core inwardly closes up at one end endoporus oral area and increase some boss 11, produce axial force, plastic seal 2 is made firmly to be connected on dynamic iron core body 1, avoid because tightening force radial when original structure closes up is wayward, efficiently solve the problem because the excessive generation distortion of radial tightening force and the too small generation of radial tightening force come off.
The cross section of described annular boss 11 is triangle, and its side near described chamfer bevel 12 is inclination shape, and opposite side is vertical with dynamic iron core body 1 inwall, and is fillet in the middle part of annular boss 11.The axial limiting power produced by annular boss 11 realizes the firm connection of plastic seal 2, avoids coming off.
In order to ensure that plastic seal 2 can closely be clamped in dynamic iron core body 1, described annular boss 11 is interference fit with the outer wall 21 of plastic seal 2.
In order to improve the installation steadiness of plastic seal 2 further, described interference fit is of a size of 0.25-0.45mm.
Embodiment: a kind of novel movable iron core of electromagnetic valve as shown in Figure 1-2, comprise dynamic iron core body 1, dynamic iron core body 1 is cylindrical, two circle annular boss 11 are provided with at one end endoporus of dynamic iron core body 1, the outer wall 21 of plastic seal assembly 2 is designed to shiny surface, conveniently be connected with other parts, dynamic iron core body 1 inner wall of end is designed with hypotenuse chamfering 12, avoiding dynamic iron core body 1 produces crooked with the mutual rigid extruding of plastic seal 2, the overlap simultaneously preventing the outer wall 21 of plastic seal 2 from extruding is piled up in end face affects performance, be interference fit between the outer wall 21 of annular boss 11 size and plastic seal 2, interference fit is of a size of 0.25-0.45mm, this design can not only avoid the rigid extruding of the outer wall 21 of annular boss 11 and plastic seal 2, and plastic seal 2 firmly can be fixed in dynamic iron core body 1, avoid the appearance of two part distortion or the problem that comes off.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its objective is to allow and be familiar with these those skilled in the art and can understand content of the present utility model implementing according to this; protection range of the present utility model can not be limited with this; all according to the utility model spirit essence done by distortion, modification or with conversion, all should contain in protection range of the present utility model.
