The invention has the advantages of simple and convenient use, high precision, good commonality, capability of being suitable for various instruments, low cost and simple manufacture.
Description
Technical field
The present invention relates to the technical field at calibration of workpieces endoporus center, relate in particular to a kind of general-purpose cent(e)ring frame.
Background technology
In shipbuilding or other industrial and agricultural productions, through regular meeting the situation that some pass through other relevant centers of workpiece endoporus cent(e)ring or pass through other relevant cent(e)ring workpiece endoporus centers appears.For example, in shipbuilding, the location of the stern tube shaft pipe assembly that poured with epoxy resin is fixing and backguy prestige light are determined each other locational axial center.Adopt laser at present mostly, straight telescope, the instrument that dial gauge etc. are advanced, they all need just can finish with the acting in conjunction of cent(e)ring frame, and traditional cent(e)ring frame is by radially adjusting the axial angle adjustment of double as, and mixed up radial position doing to influence when axial angle is adjusted, equally, when radially adjusting, will influence again and mix up axial angle position, so will adjust two positions of radial and axial angle of the endoporus of cent(e)ring frame, necessity is adjusted repeatedly, so it is more complicated, the adjustment time is long, and precision is also lower, requires also high to the operator.
Summary of the invention
The purpose of this invention is to provide a kind of general-purpose cent(e)ring frame, it is simple that it has use, and convenient, precision is higher; Shared property is good, can be suitable for various instruments; Cost is low, makes simple.
Technical scheme of the present invention is: general-purpose cent(e)ring frame, mainly by carrying bolt 1, radially adjust bolt 2, axially adjust bolt 3, annular seating 4, radially adjust seat 5, sphere centering frame 6, axially adjust seat 7 etc. and form, the seat of carrying bolt 1 is welded on the annular seating 4, and carrying bolt 1 is fixed in the workpiece endoporus; Radially adjust bolt 2 and be installed on the annular seating 4, and withstand and radially adjust seat 5; Radially adjust and be inserted in sphere centering frame 6 in the seat 5, the tail end of sphere centering frame 6 is enclosed within axial the adjustments seat 7, axially adjusts seat 7 and is installed in the axial adjustment bolt 3 of radially adjusting 5 tail end and withstands.Radially adjusting seat 5 and sphere centering frame 6 is sphere fit structures.Sphere centering frame 6 is that an end is spherical, the circular recessed sky of end face band, and the other end is cylindric, is inserted in radially adjusting in the seat 5.
The invention has the beneficial effects as follows: radially adjust seat by adjusting, adjust the radial position of endoporus, axially adjust bolt by adjusting again, adjustment is inserted in and is radially being adjusted the sphere centering frame of seat, adjust the axial angle position of endoporus, then can make general-purpose cent(e)ring frame be in required tram, so use simple, convenient, precision is also higher.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left TV structure schematic diagram of Fig. 1 of the present invention.
Among the figure: 1, carrying bolt, 2, radially adjust bolt, 3, axially adjust bolt, 4, annular seating, 5, radially adjust seat, 6, sphere centering frame, 7, axially adjust seat.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done description in further detail:
As shown in Figure 1, general-purpose cent(e)ring frame mainly by carrying bolt 1, radially adjust bolt 2, axially adjust bolt 3, annular seating 4, radially adjust seat 5, sphere centering frame 6 and axially adjust seat 7 and form.General-purpose cent(e)ring frame is installed in the workpiece endoporus, withstand workpiece endoporus inwall with carrying bolt 1, adjust carrying bolt (containing seat) 1, the center that makes general-purpose cent(e)ring frame is roughly near workpiece endoporus center, in sphere centering frame 6 front end shrinkage pools, pack into and be with cross hairs glass plate plug core, if by other relevant centers of workpiece endoporus cent(e)ring, then by dial gauge or divider calipers to the cross hairs center of band cross hairs glass plate plug core to workpiece endoporus inwall up and down or all around 4 radial directions apart from measuring, adjust and radially adjust seat 5, make 4 radial direction distances as far as possible near equating, axially adjust bolt 3 by adjusting again, adjustment is inserted in and is radially being adjusted the sphere centering frame 6 of seat 5, adjust the axial angle position of endoporus, then being with the cross hairs center of cross hairs glass plate plug core this moment promptly is workpiece endoporus center, can be by adopting laser, advanced instrument such as straight telescope with this center as other relevant centers of N Reference Alignment.If by other relevant cent(e)ring workpiece endoporus centers, then making the cross hairs center of band cross hairs glass plate plug core by above-mentioned steps earlier is workpiece endoporus center, advanced person's instrument will be as other relevant centrally aligned band cross hairs glass plate plug cores of benchmark by adopting laser, straight telescope etc. then, adjust the location of workpiece, the relevant center with other, cross hairs center of band cross hairs glass plate plug core is overlapped, then finish by other relevant cent(e)ring workpiece endoporus centers.
