Description
Technical field
The present invention relates to machining equipment field, workpiece in more particularly to a kind of elastic composite jacking mechanism and the mechanism
The determination methods that force-bearing situation and workpiece whether there is.
Background technology
It is top, it is a kind of knot for being used for the supporting workpiece when processing Model For The Bush-axle Type Parts on the lathes such as lathe, grinding machine and milling machine
Structure, when being processed on lathe, the front end of workpiece carries out origin reference location with frock clamp, and rear end is held out against with top, and is pushed up
Point is held out against by power set, so that workpiece keeps correctly relative position in machining between lathe and cutter
Put.
During with same power not only to meet dead head movement but also top tight workpiece, because to meet that dead head moves, apply
The power added can not be less than the power of dead head movement, in order to provide the force of less pressure dead head movement and top pressure
System uses separate structure more, and the more complicated manufacturing cost of mechanism is high, and control adjustment is cumbersome.
During working shaft-like workpiece, especially major axis when, if from back dead centre, often due to caused cutting in working angles
Heat change so that process axle temperature height change, the length of axle is easily changed, so must constantly adjust
Whole top tightness, it is very cumbersome to ensure being smoothed out for machining.If caused cutting heat in working angles
When amount change is big, it can only could meet processing request with the top mode compensated automatically.
In order to meet the processing request of automation, it is necessary to which tip mechanism is checked workpiece whether there is.
Tip mechanism of the prior art can not meet top automatic compensation simultaneously, realize promotion and pressure with same power
Tightly, workpiece, which whether there is, carries out inspection work.

The determination methods that part 1 whether there is, comprise the following steps：
S1, the force application system promote dead head 7 to move forward at front position, and now preceding switch 3 is connected, rear switch
5 disconnect, top 2 are introduced into working condition, can determine that for the position without workpiece 1 or workpiece 1 it is not in place；
S2, the force application system promote dead head 7 to move forward until preceding switch 3 disconnects, switch 5 is in still to disconnect shape afterwards
State, now, top 2 withstand workpiece 1, and pressure is provided by flexible member 6 suffered by workpiece 1, can determine that to there is workpiece 1, now, if
When needing the force application system larger pressure of offer, into next step S3；
S3, the force application system promote dead head 7 to move forward until preceding switch 3 is disconnected, switch 5 is connected afterwards, now work
Pressure suffered by part 1 is provided by force application system, can determine that to there is workpiece 1.
Explanation：Force application system promotes dead head 7 to move forward until " front position " can be one at front position
Point or a segment distance, it depends on the elastic deformation amount of workpiece and workpiece and is holding out against the variation of place's size.
Preferably, the force application system be hydraulic pressure, it is pneumatic, electronic in any one.
Preferably, the flexible member 6 is any one in the elastomers such as spring, rubber.
Technical scheme has the advantages that：
Dead head moves and pressure uses same dynamic source；After top 2 set flexible member 6, when need to use compared with
Hydraulic pressure, pneumatic and electronic etc. force application system can be used when big pressure, can pass through bullet when smaller pressure is needed
Property element 6 exerts a force；Workpiece 1 can be compensated automatically with the change of top 2 contact surface (such as centre bore) axial dimension by tip mechanism；Can
The position moved by dead head 7 and it is forward and backward switch on-off situation, can conveniently determine whether workpiece and pressure
Mode.
