Background technique
As market competition is more and more fierce and the raising of cost of labor, saves cost of labor and improve production and processing efficiency
Key as manufacturing industry survival and development.Industrial automation, it is intelligent become following development trend, can be people from cumbersome
It frees in tired environment, greatly improves production efficiency.Primary artificial dress may be implemented with chief and vice mainshaft digital controlled lathe
Folder can complete the process the function of the two-sided processing of single workpiece.When secondary main shaft carries out second operation work processing, how to improve
The stability of numerically controlled lathe pair main shaft rewinding becomes automation one research topic of linking.Routine techniques is placed in inner hole of spindle
One compressed spring is held by the tension top of compressed spring and completes the process workpiece and fall into rewinding box.But the mechanism rate of wear is higher,
Spring tension can be of different sizes by workpiece, so that the position disunity for falling different workpiece, causes the shape that rewinding is unstable
Condition.Then can find internal structural space also if its replacement spring pairing different workpieces has not applicable situation, and interchangeability is lower.Needle
The stability of liftout rewinding is accomplished to further increase in automation convergence process, our company is tied according to former main shaft inner space
Structure plans that research and development are realized by pneumatic cylinder material jacking mechanism by the function in finished workpiece top to rewinding box again.This device needs full
The sufficient following: 1. meet the normal use of the most of secondary spindle Lathe of company, i.e., reduce changing for former numerically controlled lathe as far as possible
Cause this；2. the unsuitable excessively high and convenient transportation of the totle drilling cost of this device；3. this device can be installed additional individually, in client's specific demand
Installation can be matched；4. working efficiency can be improved in this device, reduce on cutter because advanced wear or deterioration extent occur in viscous bits；5. this
Device stability is higher, and splicing success rate can reach 99.5% or more.
The spring material ejecting structure manufacturing cost used on the market at present is low, easy for installation.But spring service life is limited, makees
For consumables, it is difficult to ensure that in some cycles function stability.Automatic high-speed operating process in, stability be to
Close important link.If operator is not replaced before spring service life, it is not in place to generate rewinding, or even with
The serious consequence that other automated system interference are bumped against.When needing to change workpiece such as user terminal, since workpiece size is different from quality,
It then will affect the position of spring ejection workpiece, or even finished workpiece can not normally can be headed into and be received in box.It such as needs to change at this time
Spring is cumbersome with associated connecting structure, and process is more complex, and maintenance cost is higher.

Return motion flow.
In conclusion the utility model provides a kind of improved lathe assistant main shaft Lifting Device, by improving liftout dress
Set with push rod, be changed to two sections of linkings, this form push rod and air cylinder structure be it is separated, push rod can be with secondary one superhigh speed of main shaft
Rotation.It is limited on the outer ring of push rod using fixed hub, allows to more preferably be bonded with hollow pull rod, when rotating at high speed more
Stablize.Two-part Lifting Device avoids secondary main shaft high speed rotation from generating abrasion to push rod, push rod can be made to have longer using the longevity
Generation abrasion will not be contacted because of material ejection cylinder with its liftout push rod by ordering while ensure that.It is thin during the processing of workpiece
Wall pneumatic cylinder is in contraction state, and secondary main shaft and push rod high-speed rotation will not generate any influence to it.When work pieces process is completed
Afterwards, thin-walled pneumatic cylinder can just participate in this process of blanking.After workpiece is transmitted to next process, thin-walled pneumatic cylinder is in gas
It is shunk under the action of pressure, while the elastic force of compressed spring makes liftout push rod be restored to original state, enters next task
In circulation, the linking of automated production ensure that.So the utility model effectively overcome various shortcoming in the prior art and
Has high industrial utilization value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
