Description
Technical field：The present invention relates to a kind of high precision fine tuning positioner.
Background technology：, it is necessary to which 3 positioning instruments are placed in into high-precision reason during core pump three-level sealing ring is measured
On stone platform, behind its position of coarse regulation, sealing ring is placed on positioning instrument into accurate adjustment is less than the depth of parallelism of one face
0.002mm, measures the depth of parallelism of another plane.Originally instrument is a kind of screw jack, it is necessary to which sealing ring is put
On screw jack, when measuring every time, its position is always changed, and the depth of parallelism to be adjusted plane is 0.002mm, precision
Very high, adjustment good position is very time-consuming, and one sealing ring of measurement at least needs 2 hours.This instrument without scale because show, no
It can accurately be adjusted in place, the mechanism not locked, make to be required for readjusting during measurement every time.
The content of the invention：Article position can be fast, accurately adjusted it is an object of the invention to provide one kind, and reduces auxiliary
The positioner of working time.The technical scheme is that：A kind of high precision fine tuning positioner, the spiral shell of precision bolt (1)
Line part is coordinated with the nut piece (3) on fine-tuning nut (4) and fine-tuning nut (4) by screw thread, nut piece (3) end face circumference point
3 screwed holes of cloth, the first screw (2) is rotated into the screwed hole, is supported in fine-tuning nut (4) end face counterbore, fine-tuning nut
(4) there is a circle steel ball (9) in the middle of annular groove and the annular groove of base (7), the second screw (6) is arranged in steel ball mounting hole,
There is secondary ruler dial (5), secondary ruler dial (5) passes through lock-screw with base (7) between fine-tuning nut (4) and base (7)
(8) fixed, in the locking mechanism of bottom, the 3rd screw (12) is vertical with the plane of precision bolt (1) body bottom, in pin-and-hole successively
Ball (10), wedge post (11), the 4th screw (13) are installed, the 4th screw (13) withstands wedge post (11) and ball (10).
Its of the invention operation principle is：Fine-tuning nut (4) is by steel ball structure and base (7) axial restraint, and circumference is free
Rotate.Precision bolt (1) makes precision bolt (1) to rotate by wedge post (11) structure, is free to move axially.Fine-tuning nut
(4) circumference has main scale scale, has secondary ruler dial (5), secondary ruler dial (5) and bottom between fine-tuning nut (4) and base (7)
Seat (7) is fixed.Rotary fine adjustment nut (4), moves up and down precision bolt (1), using main scale and secondary ruler scale, quick adjustment
To after the position specified, the 3rd screw (12) is locked, precision bolt (1) and base (7) is fixed.
Retaining mechanism has two functions, and 1, with regulation and control fit clearance function, 2, the function being locked.
Regulate and control fit clearance function using ball (10), wedge post (11) and the 4th screw (13), ball (10) has
Elasticity, the elastic force outside to wedge post (11), the 4th screw (13) support force inside to wedge post (11) rotates the 4th screw (13)
The position of wedge post (11) can freely be controlled.There are 3 ° of inclined-planes on wedge post (11), the position of wedge post (11) more moves inward, essence
Close bolt (1) plane and the inclined-plane gap of wedge post (11) are smaller, otherwise bigger.Gap is adjusted to minimum, and precision bolt (1) is axially
Freedom of movement.
, can be with quick regulation to the position specified using main scale and secondary ruler come reading numerical values.The present invention is using M16X0.5's
There are 50 scale circumference to be uniformly distributed on accurate fine thread, main scale, main scale scale often rotates a circle change in location 0.5mm, often
Individual scale reading is to have 10 scales to be evenly distributed on main scale in 9 scales in 0.01mm, secondary ruler, and each scale reading is
0.001mm.Main scale reads 0 line number value in correspondence secondary ruler, and secondary ruler reads the numerical value of the groove overlapped with main scale, always reads number
=main scale reading+secondary ruler reading.
The present invention is referred to main scale, the scale of secondary ruler, quickly, is accurately adjusted in place, sealing ring is measured, if micro
Error, can accurately be adjusted according to difference, be measured more efficient and convenient.Measurement once sealing circle is only needed to 5 minutes now.
Advantage of the present invention has advantages below with the contrast of other similar means：
1. because with scale, can quickly it is presetting in place.
2. precision bolt (1) motion mode is linear motion, circumference is static, is that same point is contacted all the time with workpiece, it is to avoid
Other instruments are rotated by bolt to be risen, the structure inferior position of the multiple points contact of sphere, make the workpiece motion s of adjustment it is more steady,
Uniformly.
3. adjust workpiece to arrive behind the position specified, with the function being locked, it is only necessary to which accurate adjustment once, locks the
Three screws (12), can directly be used, it is not necessary to readjust during measurement sealing ring next time.
