The range of work.
Chinese patent Authorization Notice No. is CN 2659602Y, and authorized announcement date is that the utility model on December 1st, 2004 is special
Profit discloses adjusting precision holding mainshaft, include for clamp the clamping mandrel that the collet of workpiece is connected with collet with
And the splicing sleeve for supporting the clamping mandrel, the major diameter that mandrel is clamped are fixedly connected with a main tapping, the outer circle of main tapping
Radial on week to be provided with adjusting screw, adjusting screw head and the major diameter of 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 be arranged an interior annular groove and with the clamping mandrel phase clearance fit, spring clip
The rear end of head is spirally connected a pull rod being arranged in mandrel endoporus be clamped, clamping mandrel one driving member of connection and with the boss of pull rod it
Between be provided with butterfly spring and guide sleeve.
Although the device can complete the automatic clamping of workpiece, discharging process needs to be manually operated, and operation sequence ratio
It is more complex, seriously affect processing efficiency.
Invention content
The purpose of the present invention is overcoming problems of the prior art, automatic discharge, efficiency can be realized by providing one kind
High back spindle automatic discharging device.
In order to achieve the above object, technical solution of the invention is：A kind of back spindle automatic discharging device, including bullet
Property collet, material pushing needle, collet sleeve and bar feed inlet, the material pushing needle is located in elastic collet, and the elastic collet is located 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 elastic collet and
Resetting spring is provided between spacing collar, the collet sleeve is contacted by one end of bar feed inlet with push rod two, the push rod
Two other end is contacted with the galianconism of Open and close claw, and the long-armed of the Open and close claw is contacted with pneumatic actuator, the elastic collet with
It is provided with liftout spring between bar feed inlet, bar feed inlet side is provided with inductive switch, and the one of the Open and close claw
Side is provided with Thrust nut, and the Thrust nut and pneumatic actuator are located at the both sides of Open and close claw.
The cross section of the resetting spring is rectangle.
Compared with prior art, the present invention has the benefit that：
1, the present invention realizes the automatic folder of back spindle by the compound action of inductive switch, pneumatic actuator and Open and close claw
It holds, operation is easier, after processing is completed, oneself of back spindle can also be realized by devices such as resetting spring, liftout springs
Dynamic discharge, clamping entire in this way, discharging process can be automatically performed, and actuation time is short, high in machining efficiency, and due to avoiding
Human error, accuracy also higher.
2, 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 that push rod one is limited provided with spacing collar, ensure that when automatic discharge can discharge in place.
3, the cross section of resetting spring is rectangle in the present invention, and contact of such resetting spring with elastic collet can more be filled
Point, discharge effect also can be more preferable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
In figure：Elastic collet 1, material pushing needle 2, collet sleeve 3, push rod 1, resetting 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 feed inlet
13。
Specific implementation mode
Below in conjunction with description of the drawings, the present invention is described in further detail with specific implementation mode：
Referring to Fig. 1, a kind of back spindle automatic discharging device, including elastic collet 1, material pushing needle 2, collet sleeve 3 and bar charging
Mouth 13, the material pushing needle 2 is located in elastic collet 1, and the elastic collet 1 is located in collet sleeve 3, one end of the material pushing needle 2
It being 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 elastic collet
Resetting spring 5 is provided between 1 and spacing collar 6, the cross section of the resetting spring 5 is rectangle, to ensure collet sleeve
Reliable reset, the collet sleeve 3 are contacted by one end of bar feed inlet 13 with push rod 27, the other end of the push rod 27 with open
The galianconism 91 for closing pawl 9 contacts, and long-armed the 92 of the Open and close claw 9 contacts with pneumatic actuator 8, the side setting of the Open and close claw 9
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, the elastic collet 1 with
Liftout spring 12 is provided between bar feed inlet 13,13 side of bar feed inlet is provided with inductive switch 11.
