Abstract
A perpendicularity error measuring tool for opposite end surfaces of blind holes comprises a steel ball, a spindle, a bolt, a rocker arm, an opening sleeve and a dial gauge. The steel ball is mounted at the bottom of a blind hole of a part, the spindle is mounted on the bottom surface of a central shaft of the blind hole and abutted to the top of the steel ball, one end of the rocker arm is fixed onto the spindle by the aid of the bolt, the dial gauge is fixed to the other end of the rocker arm by the aid of the opening sleeve, and a measuring head of the dial gauge points to a measuring surface of the part. When rotating the measuring tool, a user can calculate the perpendicularity error of opposite end surfaces of the blind holes via numerical values indicated by the dial gauge. The perpendicularity error measuring tool for the opposite end surfaces of the blind holes has the advantages that the perpendicularity error measuring tool for the opposite end surfaces of the blind holes can measure simply, conveniently, quickly and accurately, powerfully guarantees the quality of products, and is simple in structure and convenient in manufacture.
Description
Technical field
This practical sexual type relates to a kind of mechanical component measured position error utensil, especially blind hole to end face error of perpendicularity measurer.
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
This practical sexual type 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 scheme that its technical matters that solves this practical sexual type adopts is: steel ball is contained in the bottom of part blind hole, mandrel is contained in the blind hole, the bottom surface of axle 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.
Described mandrel is H7/g6 with cooperating of described part blind hole.
The beneficial effect of this practical sexual type is, use 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
Below in conjunction with drawings and Examples this practical sexual type is further specified.
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 opening sleeve (6), and the method for utilizing opening sleeve (6) to clamp dial gauge (7) is to guarantee that dial gauge (7) is indeformable when clamping.The gauge head of dial gauge (7) refers to just can measure at the measurement face rotation measurer of part.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 degree of depth L1 that distance L 2 between the minimum point that shows by dial gauge (7), the value h of peak and minimum point, the peak and mandrel (3) insert part (1) blind hole just can calculate part (1) blind hole to end face error of perpendicularity value.As: the minimum point that dial gauge (7) shows and the difference h of peak are 0.1 millimeter, and the degree of depth L1 of blind hole is 50 millimeters, and the distance L 2 between minimum point, the peak is 100 millimeters.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.
Claims (2)
1. a blind hole is to the end face squareness measurer, form by steel ball, mandrel, bolt, rocking arm, opening sleeve and dial gauge, it is characterized in that: steel ball is contained in the bottom of part blind hole, mandrel is contained in the blind hole, the bottom surface of axle withstands on the top of steel ball; an end of rocking arm is fixed by bolts on the axle, and 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.
According to claims 1 described blind hole to the end face squareness measurer, it is characterized in that: described mandrel is H7/g6 with cooperating of described part blind hole.
