Description
Technical field
The present invention relates to Automatic manual transmission clamp art more particularly to a kind of movable contact spring assembly staking fixtures.
Background technique
Movable contact spring component is extremely important component in sealed relay, which is bonded with movable contact spring binding face
Density, contact are to ruler after the tension and stress surface size of reed rivet hole, the forming situation of contact working face etc. and component riveting
Very little consistency is directly related to the assembling quality of product subsequent handling, the technical performance and Reliability of Microprocessor of whole product, because
This, which rivets positioning fixture to it and proposes higher technical requirements.
Currently, being more generally using plane riveting, spherical surface riveting, the movable contact spring riveting dotted state formed after riveting is as schemed
1, shown in Fig. 2, it is easy that there are various forms of technological deficiencies, such as the binding face of contact and reed using both riveting methods
Between have the gap, binding face area is inadequate, bad phenomenons that fitting density is smaller, and reed feels resentful, deform etc., is unable to fully meet and move
The riveting quality demand of spring assembly.It traces it to its cause and is primarily due to, in Fig. 1, riveted using plane, in the mistake to press
Cheng Zhong, most of pressure F are perpendicular to the binding face of reed and contact, and the deformation of contact riveting portion and stress direction are in
The heart is spread around, unstressed state can be almost at edge of the contact far from riveting region, after the completion of pressing, from reed
The fitting density of binding face at rivet hole four to contact edge can gradually become smaller, or even gap shown in figure occur.And in Fig. 2
In, using spherical surface riveting method, during pressing, most of pressure F is perpendicular to spherical surface to be assembled to center, reed riveting
Hole surrounding will bear biggish extension stress, and reed riveting region will appear the phenomenon that feeling resentful, can also go out between contact and reed
Existing gap shown in figure, and will lead to the angle β in reed and change.
In movable contact spring component in use, more than riveting defect will never Tongfang face ring relay electrical contact
Can, i.e., had the gap between contact and reed binding face, binding face not enough, be bonded density it is smaller when, in the electric current of same size
In the case where, the current density between contact and reed will increase, increase the contact resistance between contact, make spring assembly mistake
Heat, deformation, reduce the contact pressure between dynamic and static contact, lead to relay complete machine overheat, failure；The variation at the angle β, gives in reed
The adjusting that product adjusts especially multichannel contact product causes bigger difficulty, will lead to relay in use, dynamic and static
Contact pressure is unstable between contact, and time of contact is asynchronous；Deformation of feeling resentful at reed riveting, can make residual between reed and contact
Biggish stress is deposited, the risk that reed produces fracture in action process is increased.To sum up, above riveting lacks limit, have
The movement failure that may cause relay, substantially reduces its reliability used.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of movable contact spring assembly staking fixtures.
The present invention is achieved by the following technical programs.

Position nail is connected on the press block by screw thread pair, and the sliding friction connection opposite with limiting slot of its end.
The banking pin quantity is 2, and is uniformly deployed on the press block outer peripheral surface.
The pre-compressed spring compression travel and it is described expand rivet rod lower end surface relative between the press block lower end surface away from
From equal.
The beneficial effects of the present invention are: passed through first using technical solution of the present invention when riveting movable contact spring component
Applying active force to compression bar, the head that makes to press is to the corresponding pressure of workpiece application, after the head that presses compresses workpiece, further through
Expand rivet rod and apply the dilating effect power dissipated along riveting point to periphery to workpiece, to force reed and contact contact surface complete
Full surface fitting.Compared with prior art, the present invention makes movable contact spring assembly staking part bear bigger pressure, fills riveting point
The contact type chamber for completely forming limited block both can guarantee the patch that is full, further increasing contact and reed of shape after contact riveting
The area of conjunction be bonded density, and can guarantee the consistency of connection point thickness size, improve the finish of contact working surface.
Movable contact spring component is improved by being applied in actual production using riveting clamp provided by the invention
Reliability is riveted, riveting dot shape obtained is full, and there has also been biggish promotions for the finish of working face, without carrying out again
Polishing can reach the use demand of product, and riveting point is bonded the contact for closely greatly reducing riveting point with movable contact spring
Resistance improves the conductive capability of movable contact spring component, effectively prevents riveting point and the phenomenon that deformation occurs, reduces at riveting
Residual stress, reduce the risk that movable contact spring is broken in use, improve the use reliability of relay.
