Abstract
The invention discloses a method for measuring the position dimensions of multiple holes. A related tool comprises a horizontal platform, a height gauge, an inner diameter measuring meter and a supporting bolt assembly. In the prior art, a precise hole position dimension measuring method is implemented by a three-coordinate measuring instrument or a projection measuring instrument, the measuring method enables the position dimensions of holes of small and medium precise parts to be measured very conveniently and precisely, but the cost is relatively high, and the measuring instrument has the requirement for a good measuring environment and a relatively-fixed placing spot and also has certain measuring range limit; for mechanical parts and structural elements with large appearance sizes, transferring is not convenient, the hole distance dimensions possibly exceed the measuring range of the three-coordinate measuring instrument or the projection measuring instrument held by common manufacturers. According to the method for measuring the positioning dimensions of the multiple holes, the hole position dimensions of large-scale parts can be precisely measured in a machining spot, measuring time is reduced, and measuring cost is lowered.
Description
Technical field
The present invention relates to field of measuring technique, more specifically relate to a kind of method of measuring porous position dimension.
Background technology
In the measuring method of prior art, the detecting instrument of conventional measurement porous position dimension has three-coordinates measuring machine or projective measuring instrument, in use these appliance requires parts self have a machined surface as measurement datum, use these instruments can the accurate position dimension that must portal to the little machining parts of physical dimension.But exceed and hold instrument range or piece surface does not have the part of machined surface as measurement datum for physical dimension, as large welded structures part, what this method just can not be quick, economical obtains measurement result.Take welding triangular support bracket as example, after adding and man-hour gusset and round steel being welded together, through CNC milling machine at round steel place hole milling, during because of installation, locate with hole, not processing plane reference field, this parts use three-coordinates measuring machine or projective measuring instrument with regard to bad measurement, bigger than normal because of accessory size, settle also inconvenient on three-coordinates measuring machine or this exact instrument of projective measuring instrument.
Summary of the invention
(1) technical matters that will solve
The technical problem to be solved in the present invention is just to provide a kind of method of hole site size of convenient, fast, economic measurement large parts.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of method of measuring porous position dimension, the instrument that the method is used comprises levelling bench, height gauge, inside diameter caliper and carrying bolt assembly; Measuring process comprises: first by three triangular in shape being placed on levelling bench of carrying bolt assembly, measured piece is placed on carrying bolt assembly and is located, adjusting carrying bolt assembly makes axially bored line be parallel to levelling bench, utilize height gauge to measure respectively the height of two datum hole vertical direction bottom buses and levelling bench, adjust carrying bolt assembly allow surveyed two highly equal, then just can measure the height of each measured hole to levelling bench, measure each hole internal diameter size in conjunction with inside diameter caliper, can calculate the position dimension portalling.
Preferably, using the processing platform of large-scale lathe or milling machine as above-mentioned levelling bench.
(3) beneficial effect
Use the present invention to measure the position dimension of the measured hole that the method for porous position dimension can be convenient, fast, economic, solved existing surveying instrument limit of range and the high problem of expense.

The carrying bolt modular construction schematic diagram of Fig. 2 for using in the present invention;
In figure: 1, measured piece, 2, carrying bolt assembly, 3, levelling bench; A, B, C, measured hole.
Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples are used for illustrating the present invention, but can not be used for limiting the scope of the invention.
The present invention measures the instrument that the method for porous position dimension uses and comprises levelling bench, height gauge, inside diameter caliper and carrying bolt assembly, measuring process comprises: first by three triangular in shape being placed on levelling bench of carrying bolt assembly, measured piece is placed on carrying bolt assembly and is located, adjusting carrying bolt assembly makes axially bored line be parallel to levelling bench (utilize dial gauge measured hole vertical direction bottom bus relative level platform beat or with determining to the distance of levelling bench whether axially bored line is parallel to levelling bench in height gauge measured hole two ends), utilize height gauge to measure respectively the height a of two datum hole vertical direction bottom buses and levelling bench, b, adjust carrying bolt assembly by a, b equates, then just can measure the height of each measured hole to levelling bench, measure each hole internal diameter size in conjunction with inside diameter caliper, can calculate the position dimension portalling.
Embodiment:
As shown in drawings, by three triangular in shape being placed on levelling bench of carrying bolt assembly, measured piece is placed on carrying bolt assembly and is located, adjusting carrying bolt assembly makes axially bored line be parallel to levelling bench (utilize dial gauge measured hole vertical direction bottom bus relative level platform beat or with determining to the distance of levelling bench whether axially bored line is parallel to levelling bench in height gauge measured hole two ends), utilize height gauge to measure respectively two datum hole A, B vertical direction bottom bus is to the height a of levelling bench, b, adjust carrying bolt assembly and make a, b equates, then utilize height gauge to measure the height c of triangular support bracket top-portion apertures vertical direction bottom bus to levelling bench.With inside diameter caliper measured hole A, internal diameter size Da, the Db of B, C, Dc respectively.Calculate each hole relative position by following formula:
Relative A hole, B hole axial line position=b+Db/2-(a+Da/2)=b-a+(Db-Da)/2
Relative A hole, C hole axial line position=c+Dc/2-(a+Da/2)=c-a+(Dc-Da)/2
Above embodiment is only for the present invention is described, but not limitation of the present invention.Although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is carried out to various combinations, revises or is equal to replacement, do not depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
