Description
Technical field
The present invention relates to a kind of mechanical component measured position error utensil, especially blind hole to end face verticality measuring instrument and measuring method.
Background technology
At present, some mechanical component are provided with blind hole and perpendicular to end face, and blind hole directly affects the usability of mechanical component on end face error of perpendicularity size.Measure blind hole to the end face vertical error, be with flat board, right angle seat, fixing and adjustable support, with the measurement bay of indicator etc., measuring process is very complicated and difficult, and is just more difficult for the large mechanical component that are difficult to move.
Summary of the invention
The invention provides a kind of blind hole to end face verticality measuring instrument and measuring method, to blind hole on mechanical component to the end face error of perpendicularity can be easy, fast, measure accurately.
The technical solution adopted for the present invention to solve the technical problems is: steel ball is contained in the bottom of part blind hole, the bottom surface that mandrel is contained in the blind hole central shaft withstands on the top of steel ball; an end of rocking arm is fixed by bolts on axle; dial gauge is fixed on the other end of rocking arm by opening sleeve, the gauge head of dial gauge refers to the measurement face at part.Rotate measurer, just can calculate blind hole to the end face error of perpendicularity by the numerical value to the dial gauge indication.
Mandrel is H7/g6 with coordinating of part blind hole.
pointer according to dial gauge during measurement is first found out highs and lows, firmly make mandrel obtain a numerical value a of dial gauge to the minimum point rotation when the gauge head of dial gauge during in minimum point, firmly make mandrel obtain a numerical value b of dial gauge to the peak rotation, firmly make mandrel obtain a numerical value c of dial gauge to the minimum point rotation when the gauge head of dial gauge during at peak, firmly make mandrel obtain a numerical value d of dial gauge to the peak rotation, (c+d) ÷ 2-(a+b) ÷ 2 is exactly the difference h of minimum point and peak, the part blind hole is to end face error of perpendicularity value=h ÷ L2 * L1.
The invention has the beneficial effects as follows, blind hole to the end face verticality measuring instrument can be easy, fast, measure accurately, strong assurance product quality.This measurer is simple in structure easily manufactured.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is that blind hole is to the structural drawing of end face verticality measuring instrument.
In figure 1, part, 2, steel ball, 3, mandrel, 4, bolt, 5, rocking arm, 6, opening sleeve, 7, dial gauge.
Embodiment
Accompanying drawing is that 16V240 cylinder cover for diesel engine upper face guide pillar installing blind is to the structural drawing of end face verticality measuring instrument.Steel ball (2) is contained in the bottom of part (1) blind hole, and mandrel (3) is contained in blind hole.The bottom surface of axle (3) withstands on the top of steel ball (2), realized the axial location of measurer, mandrel (3) selects H7/g6 with coordinating of part (1) blind hole, like this mandrel (3) just can be in blind hole flexible rotating, measurer is successfully measured.One end of rocking arm (5) is fixed on axle (3) with a bolt (4), and another bolt (4) that is contained on rocking arm (5) withstands on opening sleeve (6).Dial gauge (7) is fixed on the other end of rocking arm (5) by on opening sleeve (6).The method of utilizing opening sleeve (6) to clamp dial gauge (7) is to guarantee that dial gauge (7) is indeformable when clamping.The measurement face of the gauge head contact part of dial gauge (7) rotates measurer and just can measure.First find out peak according to the pointer of dial gauge (7) during measurement, certainly, minimum point also just with 180 ° of places of peak symmetry.The diameter of part (1) blind hole is 22 millimeters, mandrel selects H7/g6 with coordinating of part blind hole, and the gap of mandrel and part blind hole is 0.007～0.041 millimeter, and this gap is influential to measurement, particularly the gap is 0.041 o'clock, and the reading error of dial gauge (7) is larger.For this reason, can adopt following method: when the gauge head of dial gauge (7) during in minimum point, firmly make mandrel (3) obtain a numerical value a of dial gauge (7) to the minimum point rotation, firmly make mandrel (3) obtain a numerical value b of dial gauge (7) to the peak rotation.When the gauge head of dial gauge (7) during at peak, firmly make mandrel (3) obtain a numerical value c of dial gauge (7) to the minimum point rotation, firmly make mandrel (3) obtain a numerical value d of dial gauge (7) to peak rotation, should adjust the reading that dial gauge (7) makes dial gauge (7) during measurement is all positive number.(c+d) ÷ 2-(a+b) ÷ 2 is exactly the difference h of minimum point and peak, and the part blind hole is to end face error of perpendicularity value=h ÷ L2 * L1.As: the minimum point that dial gauge (7) shows and the difference h=0.1 millimeter of peak, the degree of depth L1=50 millimeter of blind hole, the distance L 2=100 millimeter between minimum point, peak.Part (1) blind hole is to end face error of perpendicularity value=h ÷ L2 * L1, i.e. 0.1 ÷ 100 * 50=0.05 millimeter.
