Description
Technical field
The utility model relates to a kind of hole non-squareness measurement instrument, belongs to machining survey instrument technical field.
Background technology
In machining is measured; usually can run into the measurement to the non-perpendicularity of two mutual upright openings; although the instrument of its measurement and means are varied; but all be indirect measurement, measurement data is many, the survey instrument complexity; the location of datum mark is also inaccurate; cause and measure the cumulative errors increasing, measuring accuracy is on the low side, can't satisfy accurately machined technical requirement.
Summary of the invention
The purpose of this utility model just provides a kind of hole non-squareness measurement instrument, is used for addressing the above problem.
The technical solution of the utility model is: a kind of hole non-squareness measurement instrument, comprise cover, the horizontal survey rod, the table bar, little ringfeder, strut, dial gauge, the vertical survey rod, big ringfeder, butter, link block and pressure regulation nail, be provided with cover from left to right successively on the horizontal survey rod cylindrical, little ringfeder and big ringfeder, its endoporus communicates with little ringfeder and big ringfeder endoporus and is provided with butter, the pressure regulation nail links with horizontal survey rod endoporus threadably, be provided with link block between butter and the pressure regulation nail, the horizontal survey rod is packed into behind the big lateral aperture and little lateral aperture of workpiece, the cylindrical of big ringfeder and little ringfeder contacts with little lateral aperture with the big lateral aperture of workpiece respectively, table bar and external threading link, the table bar is provided with strut and dial gauge and is located by screw, the vertical survey rod is set on the upright opening of workpiece, and the contact of strut and dial gauge all contacts with vertical survey rod cylindrical.
The beneficial effects of the utility model are: simple in structure, easy to operate, and the measuring accuracy height.

Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done to describe in further detail, with reference to accompanying drawing 1 as can be known, a kind of hole non-squareness measurement instrument, comprise cover 1, horizontal survey rod 2, table bar 3, little ringfeder 4, strut 5, dial gauge 6, vertical survey rod 7, big ringfeder 9, butter 10, link block 11 and pressure regulation nail 12, be provided with cover 1 from left to right successively on horizontal survey rod 2 cylindricals, little ringfeder 4 and big ringfeder 9, its endoporus communicates with little ringfeder 4 and big ringfeder 9 endoporus and is provided with butter 10, pressure regulation nail 12 links with horizontal survey rod 2 endoporus threadably, be provided with link block 11 between butter 10 and the pressure regulation nail 12, horizontal survey rod 2 is packed into behind the big lateral aperture and little lateral aperture of workpiece 8, the cylindrical of big ringfeder 9 and little ringfeder 4 contacts with little lateral aperture with the big lateral aperture of workpiece 8 respectively, table bar 3 links with cover 1 screw thread, table bar 3 is provided with strut 5 and dial gauge 6 and is located by screw, vertical survey rod 7 is set on the upright opening of workpiece 8, and the contact of strut 5 and dial gauge 6 all contacts with vertical survey rod 7 cylindricals.During measurement, earlier vertical survey rod 7 is packed into gently in the upright opening of workpiece 8, and the shoulder of noting measurement rod 7 is not adjacent to the upper surface of workpiece 8 upright openings, thereby avoid not forcing measurement rod 7 to tilt because the upper surface of workpiece 8 upright openings is vertical with the hole face, again horizontal survey rod 2 is packed in the big lateral aperture and little lateral aperture of workpiece 8, screw pressure regulation nail 12, extruding butter 10, little ringfeder 4 and big ringfeder 9 thin-walled portions are evenly expanded, little lateral aperture and the big horizontal hole surface of being close to workpiece 8 respectively, till horizontal survey rod 2 can not rotate, smear one deck machine oil at the outer round surface of horizontal survey rod 2 left ends then, refill cover 1, and with the table bar 3 usefulness thread connection of intrinsic strut 5 and dial gauge 6 on cover 1, the contact of adjustment strut 5 touches certain point on vertical survey rod 7 cylindricals, the operator can will overlap 1 with hand and slowly swing back and forth this moment, read the maximal value of dial gauge 6 and write down, take off cover 1, equally, smear one deck machine oil at the outer round surface of horizontal survey rod 2 right-hand members again, to overlap 1 and be contained in horizontal survey rod 2 right-hand members, use the same method and read the maximal value of dial gauge 6 and write down, half of the difference of two ends, dial gauge 6 left and right sides maximal value then, be upright opening center line lateral aperture little with it and the big horizontal centerline hole of workpiece 8, the non-perpendicularity between the contact distance of the contact of dial gauge 6 and strut 5.
