Abstract
The invention relates to a tool and method for measuring the perpendicularity error of a blind hole to the end surface. A steel ball is arranged at the bottom of the blind hole of a part, a mandrel is arranged in the blind hole, the bottom surface of the mandrel pushes against the top of the steel ball, one end of a rocker arm is fixed on the mandrel through a bolt, a dial indicator is fixed at the other end of the rocker arm through an open sleeve, and a measuring head of the dial indicator points on the measuring surface of the part. The measuring method comprises the following steps: rotating the measuring tool, finding out the highest point and the lowest point according to a pointer of the dial indicator, and calculating the perpendicularity error value of the blind hole of the part to the end surface through the difference value h between the lowest point and the highest point, the distance L2 between the lowest point and the highest point and the insertion depth L1 of the mandrel (3) into the blind hole of the part, which are indicated by the dial indicator. By using the tool and method for measuring the perpendicularity error of a blind hole to the end surface, measurement can be simply, quickly and accurately performed, and the quality of the product can be potently ensured. The measuring tool is simple in structure and convenient to manufacture.
Description
Technical field
The present invention relates to a kind of mechanical component measured position error utensil, especially blind hole to end face error of perpendicularity measurer and measuring method.
Background technology
At present, some mechanical component are provided with blind hole and perpendicular to end face, and blind hole directly influences the usability of mechanical component to end face error of perpendicularity size.Measure blind hole to the end face vertical error, use the measurement bay of flat board, right angle seat, fixing and adjustable support, band indicator etc., measuring process is complexity and difficult very, and is just more difficult for the great machinery part that is difficult to move.
Summary of the invention
The invention provides a kind of blind hole to end face error of perpendicularity measurer and measuring method, to blind hole on the 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 the axle; dial gauge is fixed on the other end of rocking arm by opening sleeve, and 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 numerical value to the dial gauge indication.
Mandrel is H7/g6 with cooperating of part blind hole.
Pointer according to dial gauge during measurement is found out highs and lows earlier, when the gauge head of dial gauge firmly makes mandrel obtain a numerical value a of dial gauge to the minimum point rotation during in minimum point, firmly make mandrel obtain a numerical value b of dial gauge to the peak rotation, when the gauge head of dial gauge firmly makes mandrel obtain a numerical value c of dial gauge to the minimum point rotation 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, and 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 end face error of perpendicularity measurer 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 the structural drawing of blind hole to end face error of perpendicularity measurer.
Among the figure 1, part, 2, steel ball, 3, mandrel, 4, bolt, 5, rocking arm, 6, opening sleeve, 7, dial gauge.
Embodiment
Accompanying drawing is the structural drawing of 16V240 cylinder cover for diesel engine upper face guide pillar installing blind to end face error of perpendicularity measurer.Steel ball (2) is contained in the bottom of part (1) blind hole, and mandrel (3) is contained in the blind hole.The bottom surface of axle (3) withstands on the top of steel ball (2), has realized the axial location of measurer, and mandrel (3) selects H7/g6 with cooperating of part (1) blind hole, and mandrel (3) just can rotate in blind hole flexibly like this, and measurer is successfully measured.One end of rocking arm (5) is fixed on the axle (3) with a bolt (4), and another bolt (4) that is contained on the rocking arm (5) withstands on opening sleeve (6).Dial gauge (7) is fixed on the other end of rocking arm (5) by on the 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.Find out peak earlier 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 cooperating of part blind hole, and then 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 bigger.For this reason, can adopt following method: when the gauge head of dial gauge (7) during, firmly make mandrel (3) obtain a numerical value a of dial gauge (7), firmly make mandrel (3) obtain a numerical value b of dial gauge (7) to the peak rotation to the minimum point rotation in minimum point.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 all is 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, the peak.Then part (1) blind hole is to end face error of perpendicularity value=h ÷ L2 * L1, i.e. 0.1 ÷, 100 * 50=0.05 millimeter.
