The disengaging back and forth that positioning bead is realized by rotation function controls customization pearl by moving back and forth there are no one kind to move back
It is dynamic, to realize control positioning.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of push type spring holder, can use past
Two different results can be completed in the position of multiple motion control positioning bead, i.e., a kind of same movement.
In order to solve the above-mentioned technical problem, the utility model proposes a kind of push type spring holder, including set casing,
Described set casing one end is closed end, and the other end is open ports, is equipped at open ports and installs outer eaves, and the outer eaves is equipped with spiral shell
Counterbore is followed closely, the wall of the set casing is equipped with a circular hole；In the set casing, self-styled closed end to open end be successively arranged pressure
Spring, positioning bead fixture block, power transmission pearl, rotating wheel and pressing axis, the positioning bead fixture block are equipped with card slot, the axial direction of the card slot
The shape in section is made of interconnected arc groove with rectangular channel, and a positioning bead, the positioning bead are equipped in the card slot
Diameter be greater than the circular hole diameter；The set casing is equipped with a plurality of on the interior rotary surface for being located at the open ports side
Intermeshing end-tooth, the end-tooth are equipped on axial guidance, the rotating wheel and the opposite end face of the pressing axis
For helical teeth, the outer surface of revolution of the rotating wheel is equipped with the axial groove cooperated with the axial guidance.
Further, the utility model proposes push type spring holder, wherein the positioning bead and the card slot
When arc groove face contact, the power transmission pearl is in the circular hole；More than the positioning bead when rectangular channel face contact of the card slot,
The power transmission pearl and the circular hole are in close contact.
Compared with prior art, the utility model has the beneficial effects that
The utility model positioning pin realizes quickly positioning, improves positioning using the position for moving back and forth control positioning bead
The working efficiency of control.And the utility model one side area occupied is smaller, needs to act just one kind, when realizing automatic operation
It waits just very simple, when needing that workpiece is positioned, needs to install this device when cannot remove, positioning bead protrusion is come will be
Workpiece positions.

Specific embodiment
Technical solutions of the utility model are described in further detail in the following with reference to the drawings and specific embodiments, it is described
Specific embodiment is only explained the utility model, is not intended to limit the utility model.
As shown in Figure 1, the utility model proposes a kind of push type spring holder, including set casing 2, the set casing
2 one end are closed end, and the other end is open ports, are equipped at open ports and install outer eaves 21, and the outer eaves 21 is heavy equipped with screw
The wall in hole, the set casing 2 is equipped with a circular hole 22；Interior, the self-styled closed end of the set casing 2 to open end is successively arranged pressure
Spring 1, positioning bead fixture block 4, power transmission pearl 5, rotating wheel 6 and pressing axis 7, the positioning bead fixture block 4 are equipped with card slot 41, the card
The shape of the axial cross section of slot 41 is made of interconnected arc groove with rectangular channel, and a positioning bead is equipped in the card slot 41
3, the diameter of the positioning bead 3 is greater than the diameter of the circular hole 22；The set casing 2 is returning in the open ports side
Turn surface equipped with a plurality of axial guidance 8, is equipped with intermeshing on the rotating wheel 6 and the opposite end face of the pressing axis 7
End-tooth, the end-tooth is helical teeth, and the outer surface of revolution of the rotating wheel 6 is equipped with the axial direction cooperated with the axial guidance 8
Slot.Axial guidance 8 has fettered the rotation of rotating wheel 6 and pressing axis 7, be axially moveable rotating wheel 6 can only.Work as rotating wheel
6, which move to disengaging 8 Shi Caineng of axial guidance along axial (left side in as shown), is freely rotated, and since the length of pressing axis 7 has
Limit, pressing axis 7 can not move to left enough distances to be detached from guide rail within the scope of finger-controllable, so pressing axis 7 can only axial translation,
It is the equal of the effect of a sliding block.
In the utility model, when the arc groove face contact of the positioning bead 3 and the card slot 41, the power transmission pearl 3 is embedded in
In the circular hole 22；When the rectangular channel face contact of card slot 41 described in the positioning bead 3, the power transmission pearl 3 and the circular hole 22 are tight
Contiguity touching.
When rotating wheel 6 is detached from the axial guidance 8 on 2 inner wall of set casing, according to anti-self-lock mechanism, 1 reaction of compression spring
Power can promote rotating wheel 6 to rotate, since the axial guidance 8 on set casing 2 circumferentially has the guide-track groove being alternately present (such as
Shown in Fig. 3 and Fig. 4), compression spring 1 presses closer one end of positioning bead fixture block 4, and positioning bead fixture block 4 moves axially, and positioning bead 3 has
There are two positions, and one is the lower position (falling in circular arc groove face) for allowing positioning bead 3 to fall on card slot 41, and one is positioning bead
3 jack up to high end position (i.e. the rectangular channel face contact of positioning bead 3 and card slot 41).Power transmission pearl 5 in the utility model mainly makees
The reaction force between rotating wheel 6 and compression spring 1 is reduced with being.The utility model positioning pin is by rotating wheel 6
Rotation is to control the position of positioning bead 3, to realize control positioning function.
Although the utility model is described above in conjunction with attached drawing, the utility model is not limited to above-mentioned
Specific embodiment, the above mentioned embodiment is only schematical, rather than restrictive, the ordinary skill of this field
Personnel are under the enlightenment of the utility model, in the case where not departing from the utility model aims, can also make many variations, this
It belongs within the protection of the utility model a bit.
