Description
Technical field: the present invention relates to a kind of high precision fine tuning locating device.
Background technology: in the process measuring core pump three grades of O-ring seals, need 3 orientation tools to be placed on high precision reason stone platform, behind its position of coarse regulation, O-ring seal is placed on accurate adjustment on orientation tool and makes the depth of parallelism of one face be less than 0.002mm, measure the depth of parallelism of another plane.Instrument is originally a kind of screw jack, needs O-ring seal to be placed on screw jack, when measuring at every turn, its position always changes, and the depth of parallelism that adjust plane is 0.002mm, and precision is very high, adjust position very time-consuming, measuring an O-ring seal at least needs 2 hours.This instrument, because do not have scale to show, can not accurately be adjusted to the right place, does not have the mechanism locked, all needs to readjust at every turn when making to measure.
Summary of the invention: the object of this invention is to provide one can adjust article position fast, accurately, and reduces the locating device of service working time.Technical scheme of the present invention is: a kind of high precision fine tuning locating device, nut sheet (3) on the threaded portion of precision bolt (1) and fine-tuning nut (4) and fine-tuning nut (4) passes through threaded engagement, nut sheet (3) end face circle distribution 3 threaded holes, screw 2 rotates in this threaded hole, be supported in fine-tuning nut (4) end face counterbore, a circle steel ball (9) is had in the middle of the ring groove of fine-tuning nut (4) and the ring groove of base (7), screw (6) is arranged in steel ball mounting hole, there is between fine-tuning nut (4) and base (7) secondary chi index dial (5), secondary chi index dial (5) is fixed by lock-screw (8) with base (7), in the locking mechanism of bottom, the plane orthogonal of screw (12) and precision bolt (1), rubber sphere (10) is installed in pin-and-hole successively, wedge post (11), screw (13), screw (13) withstands wedge post (11) and rubber sphere (10).
Its principle of work of the present invention is: fine-tuning nut (4) is by steel ball structure and base (7) axial restraint, and circumference freely rotates.Precision bolt (1) makes precision bolt (1) not rotate by wedge post (11) structure, axially moves freely.Fine-tuning nut (4) circumference has main scale scale, has secondary chi index dial (5) between fine-tuning nut (4) and base (7), and secondary chi index dial (5) is fixed with base (7).Rotary fine adjustment nut (4), precision bolt (1) is moved up and down, utilizes main scale and secondary chi scale, after rapid adjustment to the position of specifying, lock-screw (12), fixes precision bolt (1) and base (7).
Latch mechanism has two functions, and 1, there is regulation and control tolerance clearance function, 2, the function that is locked.
Rubber sphere (10), wedge post (11) and screw (13) is utilized to regulate and control tolerance clearance function, rubber sphere (10) has elasticity, to the elastic force that wedge post (11) is outside, screw (13) is to the inside anchorage force of wedge post (11), and rotary screw (13) can control the position of wedge post (11) freely.Wedge post (11) has 3 ° of inclined-planes, the position of wedge post (11) is moved more to the inside, and the gap, inclined-plane of precision bolt (1) plane and wedge post (11) is less, otherwise larger.Gap is adjusted to minimum, and precision bolt (1) moves axially freedom.
Utilize main scale and secondary chi to carry out reading numerical values, can quick adjustment to the position of specifying.The present invention adopts the precision thin pitch thread of M16X0.5, main scale has 50 scale circumference be uniformly distributed, main scale scale often rotates a circle change in location 0.5mm, and each scale reading is 0.01mm, secondary chi has 10 scales are even to be distributed on main scale in 9 scales, each scale reading is 0.001mm.Main scale reads 0 line numerical value on corresponding secondary chi, and secondary chi reads the numerical value of the groove overlapped with main scale, always reads number=main scale reading+secondary chi reading.
The present invention can with reference to the scale of main scale, secondary chi, and quick, accurate adjustment puts in place, measures O-ring seal, if there is micro-error, can adjust accurately according to difference, measure more efficient and convenient.Present measurement once sealing circle only needs 5 minutes.
Advantage of the present invention and other similar means contrast and have the following advantages:
1., because have scale, can presettingly fast put in place.
2. precision bolt (1) mode of motion is rectilinear motion, circumference is static, is that same point contacts all the time with workpiece, avoids other instruments and rotates rising by bolt, the structure inferior position of multiple point cantact of sphere, makes the workpiece motion s of adjustment more steadily, evenly.
3. after adjusting workpiece to the position of specifying, there is the function be locked, only need accurately adjustment once, lock-screw (12), directly can use when next time measures O-ring seal, need not readjust.
