The range of work.
Chinese patent Authorization Notice No. is CN 2659602Y, and authorized announcement date is special for the utility model on December 1st, 2004
Profit discloses adjusting precision holding mainshaft, including for clamp clamping mandrel that the collet of workpiece is connected with chuck with
And for supporting the splicing sleeve of described clamping mandrel, the big footpath for clamping mandrel is fixedly connected with a main tapping, main tapping it is cylindrical
Adjusting screw is radially arranged on week, adjusting screw head and the big footpath for clamping mandrel are inconsistent, and collet is configured in main shaft
In the taper hole of head front end, the rear portion of main tapping sets an interior annular groove and coordinated with described clamping mandrel phase gap, spring clip
The rear end of head is spirally connected a pull bar being arranged in clamping mandrel endoporus, clamping mandrel connect a driving member and with the boss of pull bar it
Between be provided with butterfly spring and guide pin bushing.
Although the device can complete the automatic clamping of workpiece, discharging process needs are manually operated, and operation sequence ratio
It is more complicated, have a strong impact on processing efficiency.
The content of the invention
The purpose of the present invention is to overcome problems of the prior art, there is provided one kind can realize automatic discharge, efficiency
High back spindle automatic discharging device.
To realize object above, technical solution of the invention is：A kind of back spindle automatic discharging device, including bullet
Property chuck, material pushing needle, collet sleeve and bar charging aperture, the material pushing needle is located in collet, and the collet is positioned at folder
In headgear, the material pushing needle is threadedly coupled with push rod one, and the collet sleeve is threadedly coupled with spacing collar, the collet and
Back-moving spring is provided between spacing collar, the collet sleeve contacts by one end of bar charging aperture with push rod two, the push rod
Two other end contacts with the galianconism of Open and close claw, and the long-armed of the Open and close claw contacts with pneumatic actuator, the collet with
Liftout spring is provided between bar charging aperture, the bar charging aperture side is provided with inductive switch.
The side of the Open and close claw is provided with Thrust nut, and the Thrust nut and pneumatic actuator are located at Open and close claw respectively
Both sides.
The cross section of the back-moving spring is rectangle.
Compared with prior art, the present invention has the benefit that：
1st, the present invention realizes the automatic folder of back spindle by the compound action of inductive switch, pneumatic actuator and Open and close claw
Hold, operation is easier, and after machining, oneself of back spindle can also be realized by devices such as back-moving spring, liftout springs
Dynamic discharge, so whole clamping, discharging process can be automatically performed, and actuation time is short, high in machining efficiency, and due to avoiding
Human error, accuracy are also higher.
2nd, the present invention is provided with Thrust nut in the side of Open and close claw, it is therefore prevented that the action of Open and close claw is excessive, ensure that folder
Hold precision；The action of push rod one is limited there is provided spacing collar, ensure that when automatic discharge can discharge in place.
3rd, the cross section of back-moving spring is rectangle in the present invention, and contact of such back-moving spring with collet can more be filled
Point, discharge effect also can be more preferable.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：Collet 1, material pushing needle 2, collet sleeve 3, push rod 1, back-moving spring 5, spacing collar 6, push rod 27, gas
Dynamic actuator 8, Open and close claw 9, galianconism 91, long-armed 92, Thrust nut 10, inductive switch 11, liftout spring 12, bar charging aperture
13。
Embodiment
Below in conjunction with brief description of the drawings, the present invention is further detailed explanation with embodiment：
Referring to Fig. 1, a kind of back spindle automatic discharging device, including collet 1, material pushing needle 2, collet sleeve 3 and bar charging
Mouth 13, the material pushing needle 2 is located in collet 1, and the collet 1 is located in collet sleeve 3, one end of the material pushing needle 2
It is threaded, the material pushing needle 2 is threadedly coupled with push rod 1, and the length of material pushing needle 2 can make appropriate change as needed, but
It is unsuitable long, otherwise influence bar can clamping length, the collet sleeve 3 is threadedly coupled with spacing collar 6, the collet
Back-moving spring 5 is provided between 1 and spacing collar 6, the cross section of the back-moving spring 5 is rectangle, to ensure collet sleeve
Reliable reset, the collet sleeve 3 contact by one end of bar charging aperture 13 with push rod 27, and the other end of the push rod 27 is with opening
The galianconism 91 for closing pawl 9 is contacted, and long-armed the 92 of the Open and close claw 9 contacts with pneumatic actuator 8, and the side of the Open and close claw 9 is set
Have a Thrust nut 10, the Thrust nut 10 and pneumatic actuator 8 are located at the both sides of Open and close claw 9 respectively, the collet 1 with
Liftout spring 12 is provided between bar charging aperture 13, the side of bar charging aperture 13 is provided with inductive switch 11.
During processing, the bar that main shaft processes soon enters from bar charging aperture 13, when bar enters the elasticity of back of the body main shaft
When in chuck 1, bar can promote material pushing needle 2 to move backward, and when moving to certain position, touch inducing switch 11, sensing is opened
Closing 11 and be signaled to pneumatic actuator 8, pneumatic actuator 8 moves forward, promotes long-armed the 92 of Open and close claw 9 up to move, from
And Open and close claw 9 is rotated, the galianconism 91 of Open and close claw 9 then promotes push rod 27 to move backward, so as to promote collet sleeve 3 to make accordingly
Motion, is applied to collet 1, so that the Automatic-clamping of collet 1 by the conical surface of collet sleeve 3.
After machining, Digit Control Machine Tool sends a signal to pneumatic actuator 8, and at this moment pneumatic actuator 8 moves backward,
Open and close claw 9 is rotated counterclockwise and resetted in the presence of back-moving spring 5, and collet sleeve 3 is multiple forward in the presence of back-moving spring 5
Position unclamps collet 1, and push rod 1 pulls material pushing needle 2 that bar is ejected so as to realize certainly in the presence of liftout spring 12
Dynamic discharge.
