Description

The pick-up unit of measured hole face runout and axially bored line verticality thereof

Technical field

The utility model relates to the pick-up unit of a kind of measured hole face runout and axially bored line verticality thereof, particularly measures the pick-up unit of non-rotary body parts drilling face runout and axially bored line verticality thereof.

Background technology

In the prior art, the drilling of non-rotary body parts often will be beated to the verticality of its axially bored line and hole end surface and be detected, object such as the non-rotary body assembly detection of forming by a machine folder part and foundry goods shown in Figure 1, because its none plane of assembly part external form is vertical with axially bored line, not having can be for the plane of detection and localization, adopt the detection of conventional sense measured hole face runout and axially bored line verticality thereof, generally be to clamp part with unit clamp, the alignment holes axis upward detects to the three-dimensional machines again.When measuring Circular Run-out Tolerance, should on some faces of cylinder, carry out usually, get and record the greatest circle jitter values as the Circular Run-out Tolerance value.If but the flatness tolerance of tested surface relatively its circle permissible value of beating is very little, and, allow only to measure a face of cylinder when tested surface diameter not quite or when little ring surface and step surface.If the tested end face of workpiece is bigger, allow the circle jitter values less again, then should suitably increase measurement point; If the measurement total run-out then should make clock gauge radially measure on whole end face.Because end face is different with the measurement that interior axially bored line circle is beated to foreign round with end face with the measurement of endoporus axis verticality to foreign round, and Circular Run-out Tolerance is zero, not necessarily there is not the error of perpendicularity, so, can not measure the verticality of end face with the method for measuring Circular Run-out Tolerance from the form and position tolerance definition.Therefore, which kind of detection tool structurally all should satisfy above-mentioned requirements.

Based on above-mentioned requirements, prior art usually needs the workman constantly to adjust the position of detection when detecting, and the weak point of this detection mode is that the detection link is many, detection speed is slow, and efficient is low, and is long in time limit, equipment cost height, quality be cannot say for sure to demonstrate,prove, and detected product percent of pass is low.Be the drillings of the above-mentioned non-rotary body parts of puzzlement always, detect the difficult problem that its verticality and hole end surface are beated.

Summary of the invention

The purpose of this utility model is to have weak point at above-mentioned prior art, provides a kind of simple in structure, and measurement links is few, and cost is low, the efficiency of measurement height, and highly versatile can fast, accurately detect the pick-up unit of hole end surface and axially bored line verticality.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of pick-up unit that detects hole end surface and axially bored line verticality thereof, comprise, a gauge head that rotates in the tested part hole is justified the dial test indicator of beating with detecting, it is characterized in that, it also comprises the survey pin of a deep enough measured hole of energy and axially is connected the lever of surveying pin, this lever vertically is assemblied in the adjustment hole of dial holder, and parallel with the table body of the dial test indicator of dial holder upper end assembling, the clock gauge gauge outfit writes down the detection indicating value of a plurality of positions rotationally at the tested surface of tested part.

The utility model defines from form and position tolerance, flatness tolerance according to workpiece end face, very little to the axis verticality tolerance, and when measured face is little ring surface and step surface, can come measuring junction to face the verticality of axis with the method for measuring Circular Run-out Tolerance, with the dial test indicator that gauge head that rotates in the tested part hole and detection circle are beated, the method measuring junction of check end surface full jumping has greatly improved detection efficiency and detection quality in the face of the verticality of axis.This installs cubing only by four parts, three standard screws, and a dial test indicator, the quick hole end surface that connects to form with the dial test indicator detection head by assembling detects, and has guaranteed detected product percent of pass.Solve the drilling of non-rotary body parts, detected the difficult problem that its verticality and hole end surface are beated.

Pick-up unit is simple in structure, and measurement links is few, and cost is low, the efficiency of measurement height, and manufacturing expense is low, easy to detect quick, and highly versatile can be widely used in the detection of all kinds of parts.

Description of drawings

Below, in conjunction with the accompanying drawings and embodiments the utility model is further specified.

Fig. 1 is the organigram that the utility model detects the pick-up unit of hole end surface and axially bored line verticality thereof.

Fig. 2 is one of the present utility model and detects principle schematic.

Fig. 3 is the view that a kind of non-rotary body parts are shaped on hole and end face thereof.

Among Fig. 1: 1 lever, 2 dial holders, 3 table body dog screws, 4 dial test indicators, 5 gauge head anti-turn screws, 6 gauge heads, 7 survey pin, 8 screws, 9 gauge outfits.

Embodiment

Consult Fig. 1, the survey pin 7 of a deep enough measured hole of energy and the main body of the lever 1 special hole end face that axially is connected survey pin 7 to axially bored line verticality cubing.One end of gauge head 6 was pressed in above-mentioned 1 coaxial the joining of lever of Kong Zhongyu of surveying pin 7, was shaped on screw hole on it, and it can fastening survey pin 7 by gauge head anti-turn screw 5, prevents gauge head 6 rotation in surveying pin 7.Lever 1 one ends are pressed in another stomidium of surveying pin 7.Dial framework 2 is gone into an end of lever 1 by screw 8 by its lower end borehole jack, tightening prevents that dial holder 4 from rotating in lever.Lever 1 one ends are pressed into to be surveyed in pin 7 holes, and an end vertically is assemblied in the adjustment hole of dial holder 2 belows, and parallels with the table body of the dial test indicator 4 of dial holder 2 upper ends assembling.Dial test indicator 4 one ends are assemblied in dial holder 2 upper end holes versatilely, carry out location positioning by table body dog screw 3.After the check point position was determined, table body dog screw 3 can be fixed, and prevents that dial test indicator 4 from rotating in lever dial framework 2.To be placed on pick-up unit during measurement and put into tested part,,, write down the detection indicating value of a plurality of positions rotationally at the tested surface of tested part when the sphere contact of clock gauge gauge outfit 9 is placed in the tested part hole with clock gauge zeroing.The maximum difference of indicating value is exactly that tested surface is to datum hole axis verticality error.Hole end surface is beated and the axially bored line verticality thereby can measure.

Consult Fig. 2 since the flatness tolerance (0.01mm) of stage face its squareness tolerance (0.06mm) is very little relatively, again because tested step surface is little, therefore can check verticality by measuring Circular Run-out Tolerance.In testing process, workpiece 10 stepped hole end faces have the verticality requirement to the datum hole axis, pick-up unit is put into the tested part hole locatees with gauge head 6 diameter axle journals, the sphere contact of clock gauge gauge outfit 9 contacts with tested surface, with the clock gauge zeroing, make 180 ° of pick-up unit revolutions then, gauge head 6 rotates in the tested part step surface simultaneously, clock gauge gauge outfit 9 is write down the indicating value of clock gauge in a plurality of positions of tested part, the maximum difference of indicating value is exactly that tested surface is to datum hole axis verticality error.This direct measurement is directly to measure measured parameter, and its value is directly read by instrument, is called direct measuring method.
