When being squeezed due to original supporting block and armature, whole face contact, armature stress deformation is smaller, and there are spools and armature to connect
It is not firm to connect, and occurs in use process, spool and armature break-off.
Utility model content
The main purpose of the utility model is to provide a kind of throttle valve core press fitting devices, can effectively solve background skill
The problems in art.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of throttle valve core press fitting device, including cylinder, the piston being arranged in cylinder, the work being fixedly connected with the piston
Stopper rod, the cylinder lower end are equipped with upper plate, and vertical between the upper plate two sides and bottom plate to be equipped with two root posts, the bottom plate is equipped with
Spring, the spring upper end are equipped with mandril, and the mandril upper end is equipped with supporting block, and the supporting block upper end is equipped with boss, and institute
It states supporting block and boss and is equipped with the through-hole passed through for spool, the mesoporous that the spool passes through armature enters through-hole, the piston rod,
Spring, mandril, supporting block and boss center on the same axis, the diameter of the supporting block is greater than the diameter of boss.
Further, the upper plate lower end is fixed with guide sleeve, and the bottom plate upper end is fixed with lower guide sleeve, it is described on
The center of guide sleeve and lower guide sleeve is on same axle center.
Further, the supporting block upper end is equipped with support sleeve, to fixed support block.
Further, the spool outer circle has annular groove, and the armature deformed part is squeezed into spool annular groove outside, is formed whole
Body.
Further, the supporting block is fixed on guide holder.
Further, the armature is quenchless pure iron.
Compared with prior art, the utility model has the following beneficial effects:
A kind of throttle valve core press fitting device reduces supporting block and armature end by the way that boss is arranged in the upper end of supporting block
The contact surface in face makes armature close to mandrel concave ring groove location local pressure, causes the extrusion of armature part in press-fitting,
Deformed part is squeezed into spool annular groove outside, reaches armature and is securely connect with spool, to form entirety；
Armature hole is easier squeezed and deformed by this kind of device, and armature is securely connected as one with spool, avoids idol
The generation of spool and armature obscission in part use.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of throttle valve core press fitting device, including cylinder 1, the piston being arranged in cylinder 12, with
The piston rod 3 that piston 2 is fixedly connected, 1 lower end of cylinder is equipped with upper plate 4, vertical between 4 two sides of upper plate and bottom plate 5 to set
There are two root posts 6, the bottom plate 5 is equipped with spring 7, and 7 upper end of spring is equipped with mandril 8, and 8 upper end of mandril is equipped with supporting block
9,9 upper end of supporting block is equipped with boss 10, and the supporting block 9 and boss 10 are equipped with the through-hole passed through for spool 11, described
The mesoporous that spool 11 passes through armature 12 enters through-hole, the piston rod 3, spring 7, mandril 8, supporting block 9 and boss 10 center
On the same axis, the diameter of the supporting block 9 is greater than the diameter of boss 10.
Wherein, 4 lower end of upper plate is fixed with guide sleeve 401, and 5 upper end of bottom plate is fixed with lower guide sleeve 501, institute
The center of guide sleeve 401 and lower guide sleeve 501 is stated on same axle center.
Wherein, 9 upper end of supporting block is equipped with support sleeve, to fixed support block 9.
Wherein, 11 outer circle of spool has annular groove, and 12 deformed part of armature is squeezed into 11 annular groove outside of spool, is formed
It is whole.
Wherein, the supporting block 9 is fixed on guide holder 13, is guaranteed coaxial.
Wherein, the armature 12 is quenchless pure iron, and quality is soft, is easy to be press-fitted.
It should be noted that a kind of working principle of throttle valve core press fitting device of the utility model is to pass through spool 11
