The housing central section is equipped with the cavity of longitudinal direction, and the upper end of cavity is rectangle structure, and the lower end of cavity is up-narrow and down-wide cone
Structure, cavity is interior to be equipped with pull rod, fore-set is movably equipped in pull rod, two parts are exposed independent from outside pull rod fore-set up and down, and top is exposed
Fore-set and the piston rod of outside cylinder connect, outside cylinder can promote fore-set straight down or to be moved upwards in pull rod, cavity
Lower end is equipped with collet, and the outer wall of collet is in contact with the inner wall of cavity, and collet upper part is embedded in housing
In the cavity at middle part, collet is connected by round nut with pull rod, and the top of cavity is provided distributed over the interior gas of cavity both sides
Cylinder, inside cylinder are connected by clamp spring with the pull rod on cavity, inside cylinder lower part and spring longitudinally disposed on the inner wall of cavity both sides
Connection, the other end of spring is connected with collet, and inside cylinder the downward compression movement of push the spring and can synchronously drive pull rod
Move downward, meanwhile, spring push the spring collet moves downward, at this point, inside cylinder, pull rod, spring and collet together to
Lower movement；The collet is cone structure, and collet includes the rectangular chamber of upper end setting and the cone tail of lower end setting
Portion, the lower part of pull rod is deeply to rectangular intracavitary, and the fore-set that lower part is exposed gos deep into cone afterbody, and cone afterbody is equipped with pin
Axis, axis pin are contacted with the fore-set of top.
Further, the cone afterbody includes body and sets the clamping jaw of body lower part, and clamping jaw is set around the circle of body one
It puts and is not contacted between each clamping jaw, collet is moved upwardly or downwardly by spring under the action of inside cylinder and spring are common,
So that clamping jaw is moved back and forth in the rectangular region of cavity and conical zone：When clamping jaw is in rectangular region, clamping jaw is in just
Normal state, at this point, clamping jaw can just clamp axis pin；When clamping jaw is in conical zone, clamping jaw is in softened state, at this point, folder
Pawl can unclamp axis pin, and when clamping jaw completely disengages conical zone and departs from housing, axis pin is unclamped and departed from from collet completely.
Further, the inside cylinder and case contact part are equipped with several sealing rings, can prevent gas or liquid into
Enter, influence inside cylinder movement.
Further, the inside cylinder and pull rod contact portion are equipped with several sealing rings, can prevent gas or liquid into
Enter, influence inside cylinder movement.

Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings：
As shown in Figure 1：The kind pin mechanism of a kind of positioning for machining center, including outside cylinder 1, inside cylinder 4, housing 6, spring
8th, collet 9, fore-set 10, straight pin 11 and pull rod 12, it is characterised in that：6 upper end of housing is provided with outside cylinder 1, institute
The cavity that 6 middle part of housing is equipped with longitudinal direction is stated, the upper end of cavity is rectangle structure, and the lower end of cavity is up-narrow and down-wide cone knot
Structure is equipped with pull rod 12 in cavity, is movably equipped with fore-set 10 in pull rod 12, fore-set about 10 two parts be exposed independent from outside pull rod 12,
Top expose fore-set 10 be connected with the piston rod of outside cylinder 1, outside cylinder 1 can promote fore-set 10 in pull rod 12 straight down or
It moves upwards, the lower end of cavity is equipped with collet 9, and the outer wall of collet 9 is in contact with the inner wall of cavity, collet 9
Upper part is embedded in the cavity at 6 middle part of housing, and collet 9 is connected by round nut 7 with pull rod 12, and the top of cavity is set
Be distributed the inside cylinder 4 in cavity both sides, inside cylinder 4 is connected by clamp spring 3 with the pull rod 12 on cavity, 4 lower part of inside cylinder with
Longitudinally disposed spring 8 connects on the inner wall of cavity both sides, and the other end of spring 8 is connected with collet 9, and inside cylinder 4 can promote
8 downward compression movement of spring simultaneously synchronously drives pull rod 12 to move downward, meanwhile, 8 push the spring collet 9 of spring moves downward,
Inside cylinder 4, pull rod 12, spring 8 and collet 9 move downwardly together at this time；The collet 9 be cone structure, spring
The cone afterbody that collet 9 includes the rectangular chamber of upper end setting and lower end is set, the lower part of pull rod 12 is deeply to rectangular intracavitary, lower part
The fore-set 10 of exposing gos deep into cone afterbody, and cone afterbody is equipped with axis pin, and axis pin is contacted with the fore-set 10 of top.
Further, the cone afterbody includes body and sets the clamping jaw of body lower part, and clamping jaw is set around the circle of body one
It puts and is not contacted between each clamping jaw, collet 9 is transported up or down by spring 8 under the action of inside cylinder 4 and spring are common
It is dynamic so that clamping jaw is moved back and forth in the rectangular region of cavity and conical zone：When collet 9 is completely in housing 6, this
When, clamping jaw can just clamp axis pin；When clamping jaw exposes outside housing, clamping jaw is in softened state, at this point, axis pin is sent by shell
In collet 9.
Further, the inside cylinder 4 is equipped with several sealing rings 5 with 6 contact portion of housing, can prevent gas or liquid
Into influencing inside cylinder 4 and move.
Further, the inside cylinder 4 is equipped with several sealing rings 5 with 12 contact portion of pull rod, can prevent gas or liquid
State enters, and influences inside cylinder 4 and moves.
Further, the outside cylinder 1 is connected by cylinder top tip 2 with fore-set 10.
Further, the collet 9 is metal material.
Further, the axis pin is straight pin 11.
The principle of the present invention：First, inside cylinder push the spring is compressed, and then push the spring collet moves downward, bullet
The clamping jaw of spring collet exposes outside housing so that collet opens, by axis pin（Such as straight pin）It is sent into collet, spring
Collet is due to the round nut barrier effect of upper end so that collet cannot entirely fall in lower part namely the collet of cavity
Always have in the cavity for being partially left at housing, synchronously, subsequent outside cylinder disconnects source of the gas, is stopped, and inside cylinder is returned in spring
Under the active force of spring-go original, inside cylinder is moved up, collet up moves, and the clamping jaw of collet gradually revert to shell
In vivo so that collet is tightened so that collet clamps axis pin, until spring is restored to original shape, axis pin is complete at this time
It is complete to clamp；And then, outside cylinder connection source of the gas, starts to work, and outside cylinder is by cylinder top tip quick washing fore-set fore-set by pin
Axis is squeezed into the through hole of workpiece, completes kind of a pin job.Above-mentioned work is cycled successively, you can is carried out continuously kind of a pin job.
The above embodiments and description only illustrate the principle of the present invention and most preferred embodiment, is not departing from this
On the premise of spirit and scope, various changes and modifications of the present invention are possible, these changes and improvements both fall within requirement and protect
In the scope of the invention of shield.
