Embodiment
Below in conjunction with accompanying drawing, the utility model is done to further detailed description:
Referring to Fig. 1, the utility model comprises the columniform shell 1 of hollow, and the top of shell 1 offers the circular hole for putting into workpiece for measurement 2; Shell 1 inside is divided into two-layer up and down, upper strata is provided with three upper strata measuring staffs 3, these three upper strata measuring staffs 3 are evenly arranged on the shell 1 horizontal circumference in upper strata, and the both sides of three upper strata measuring staffs 3 are all fixed with pinion and rack, and two pairs of adjacent pinion and racks are meshed; In the upper strata of shell 1, be provided with guide groove 5, upper strata measuring staff 3 is arranged in guide groove 5.Shell 1 lower floor is provided with three lower floor's measuring staffs 4, and these three lower floor's measuring staffs 4 are evenly arranged on the shell 1 horizontal circumference of lower floor, and the both sides of three lower floor's measuring staffs 4 are all fixed with pinion and rack, and two pairs of adjacent pinion and racks are meshed; Pinion and rack comprises pitch wheel 7 and tooth bar 8, and wherein, tooth bar 8 is fixed on the side of upper strata measuring staff 3 or lower floor's measuring staff 4 of its corresponding side; One side of gear 7 is meshed with tooth bar 8, and opposite side is meshed with the gear of another group pinion and rack.The rear end of each upper strata measuring staff 3 and lower floor's measuring staff 4 is all connected on the inwall of shell 1 by back-moving spring 9, the leading section of each upper strata measuring staff 3 and lower floor's measuring staff 4 is inclined-plane, when workpiece for measurement is inserted, can promote upper strata measuring staff 3 and lower floor's measuring staff 4 outwards moves downwards.The end face of the bottom surface of upper strata measuring staff 3 and lower floor's measuring staff 4 is respectively arranged with the block 6 cooperatively interacting.Block place is provided with the range sensor of measuring displacement difference between levels measuring head, in shell 1, is provided with data handling system, and display is also installed on the end face of shell 1; Wherein, range sensor is connected with the data input pin of data handling system, and the result output terminal of data handling system is connected with display.Data handling system is the poor single-chip microcomputer that is calculated as tapering of the relative displacement for range sensor is collected.
Principle of the present utility model and the course of work
The utility model comprises cylinder blanket, the each six pairs of pinion and racks of levels, three upper strata measuring staffs, three lower floor's measuring staffs, back-moving spring, range sensor, data handling system, display etc.The motion of rack-and-pinion adopts the mode of interlock, has guaranteed that the home position of three contact places circles of every layer of measuring staff is constant, and then can guarantee that the displacement of three bars is identical, and the end of measuring staff is inclined-plane, just inserts with measured workpiece.
When use, workpiece inserts downwards, contact upper strata measuring staff end chamfer, promotes it and outwards moves, and upper strata measuring staff moves to certain position, upper and lower two blocks contact, lower floor's measuring staff is outwards moved by thrust, and now, upper layer of contact (measuring staff top and workpiece contact site) place diameter of a circle is less than in lower floor's measuring staff end chamfer along place circular diameter, to guarantee that workpiece can enter smoothly, do not blocked by lower floor's measuring staff.The center of upper and lower two-layer measuring staff is vertical with diameter measurement plane, and this design makes workpiece insert after measuring instrument and can automatically locate, and measuring instrument is measured in the situation that being not horizontal positioned precisely same.
Subsequently, lower layer of contact contacts with the workpiece conical surface.Along with workpiece continues to move down, lower floor's measuring staff continues outwards mobile, and because workpiece cone element and vertical direction angle are less than the angle (instrument be mainly suitable for measure compared with Small Taper workpiece) of upper and lower block Contact levels corresponding contact contact line and vertical direction, so now lower floor's measuring staff movement velocity is fast compared with upper strata, but block is in outside below, so be not subject to stop limits above, so just can guarantee six equal real-time contact of contact of workpiece and levels.Back-moving spring has been installed at rear portion at each measuring staff, has guaranteed contacting of sensor and axle, makes measurement result more accurate, has avoided to a certain extent the generation of error result.
Range sensor of the present utility model is connected with single-chip microcomputer, and numerical value is calculated result show on display by pre-set program after sending into single-chip microcomputer.Also higher in order to guarantee the precision of precision sensor of measuring instrument, the sensor of different accuracy also can be installed according to different accuracy requirements.During insertion, sensor gathers three secondary data, passes to data handling system, through data handling system process after by result output display on display.In measuring process, levels measuring staff all outwards moves a certain distance under the thrust of measured piece, when measuring workpiece and enter measuring state completely by being arranged on range sensor on lower floor's measuring staff, (when six contacts all contact) lower floor's measuring staff is with respect to the displacement variable Δ S of upper strata measuring staff, because the distance of levels contact is certain L, finally draw the tapering of measured piece with formula 2 Δ S/L again.The measurement of displacement difference Δ S is that the sensor by being arranged between upper and lower block is realized, and the distance between levels is pre-set, and calculating realizes by single-chip microcomputer, finally result is directly presented on the display of instrument.
The utility model has the advantage of:
1. measuring accuracy is high.This taper measurer adopts 6 automatic real-time contact formulas to measure, and effectively reduces measuring error; Meanwhile, for same measured piece, instrument kinetic measurement can be obtained multi-group data, has effectively reduced stochastic error, has improved measuring accuracy;
2. automaticity is high, greatly improves and measures efficiency.In testing process, by the manual lifting workpiece of operating personnel, all the other measuring processes and instrument homing action complete automatically by instrument, must human intervention.Can greatly shorten Measuring Time, improve and measure efficiency.
3. economical and practical, applied range, is easy to popularize.This instrument, because mechanism is simple, is manufactured relatively easy; Instrument can be widely used in detection and the sorting of all types of accurate post class parts, the such as automatic detection of oil pump nozzle industry plunger part etc.;
