[detailed description of the invention]
In describing the invention, it is to be understood that term " radially ", " on ", " outward ", the orientation of the instruction such as " vertically " Or position relationship is based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, and It not to indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore It is not considered as limiting the invention.In describing the invention, except as otherwise noted, " multiple " are meant that two or two More than individual.
In describing the invention, it should be noted that unless otherwise clearly defined and limited, term " is arranged ", " phase Even ", " connection " should be interpreted broadly, for example, it may be fixing connection, it is also possible to be to removably connect, or be integrally connected;Can To be mechanical connection, it is also possible to be electrical connection;Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, Ke Yishi The connection of two element internals.For the ordinary skill in the art, can understand that above-mentioned term is at this with concrete condition Concrete meaning in invention.
The invention discloses the aligning method that a kind of part is angular, its step is as follows:
(1) processing technique alignment holes or stretch face: according to the construction features processing technology alignment holes 4 of part 1, and in technique Processing technique alignment holes 4-1 and installing hole 4-2 on centering block 4;On the zero degree position of chuck body processing technique alignment holes or Angularly stretch face;
(2) clamping device: fixture is arranged on lathe, technique alignment holes on centering fixture or angularly stretch face, if Zero setting degree angular position, compressing fixture;
(3) part is installed: be arranged on fixture by part 1, part 1 installed and on limit, has the part in angular hole, installs Time part 1 and fixture angular relation by the setting circle on the alignment pin on fixture, positioning spigot and part, angularly position Kong Wei One determines;Part 1 is installed and on limit, does not has angular hole or hole, angular location to need to use technique centering block when being not easy to centering Auxiliary transverse alignment part is angular;Check errorless rear compressing component;
(4) mounting process centering block: the technique centering block made according to part practical structures is passed through on part existing Hole is arranged on part;
(5) determine angularly: for fixture can be utilized to determine zero degree angular position, use dial gauge to play table and stretch fixture The face that angularly stretches or centering fixture on alignment holes determine zero degree position;Angular for fixture can not be utilized to determine, centering Fabrication hole on part 1 or technique alignment holes 4-1 on technique centering block 4, now 0 degree of angular position of part will be the most true Fixed, it is 0 degree of position by arranging this position in the current angular position angular parameter column in lathe parameter arranges instruction.
Referring to shown in Fig. 1 to Fig. 4, the present invention also provides for the aligning method fixture that a kind of part is angular, including base The fixture being arranged on lathe, the base 2 of fixture is vertically arranged with L-shaped part 1, part 1 is provided with for auxiliary transverse alignment Circular arc technique centering block 4, clamp base 2 is provided with multiple pressing plate 3 for compressing described part 1 bottom surface.
Technique centering block 4 outer radial is provided centrally with technique alignment holes 4-1, and technique alignment holes 4-1 is blind hole, and technique is looked for It is provided with the installing hole 4-2 for positioning assembling on positive block 4;Technique centering block 4 freely can move on to be processed of part 1 Dynamic, coordinated with the hole on part 1 by installing hole 4-2 and carry out location centering.
Bore as a example by boring side and end-face hole by certain model aircraft engine turbine casing: the end face of certain machine turbine casing and outer A, B, C, D, E, F, G, H, J, K, L, M, N totally 13 group different size, different angular holes group is distributed on wall, and in processing, other owns Kong Zuqian, only at two, C hole between installation limit has processed and has put in place, remaining hole group is not the most processed, porose group Angular position is all determined angular position by the C hole group processed.The former processing method 0 degree of angular position before determining processing Time, take to insert in the arbitrary hole in 42 C holes by an alignment pin, then use lever meter to play table in the both sides of alignment pin and determine The center of alignment pin thus indirectly determine the position in C hole, then on the basis of this C hole, by C disc spins 6 °, determine zero 0 degree of angular position of part.Said method firstly there are the position with alignment pin during operation and indirectly determines the position in C hole Existing and position inaccurate problem, secondly when beating the both sides of alignment pin with lever meter, working place is little, and inconvenient operation plays table Result is inaccurate, the problem secondly operational error easily occur when coordinate rotates angular.
The technique centering block processing method currently using band technique alignment holes carries out clamping to turbine casing process side face Centering, the steps include: first processing technology centering block, has at 2 installing hole for installing limit with turbine casing on technique centering block On location, 2 C holes assembling, the radial design at mounting blocks has the technique alignment holes of ф 8 at, with wherein 1 at installing hole It is angularly 6 °;Mounting process block again, after attaching components to compress on fixture, solid in technique block is arranged on any 2 C holes Fixed;Finally, according to the radial direction alignment holes on centering mounting blocks, this position is set to 0 degree.With the method centering part angular time tool There is the advantage that accuracy quick, simple is high, greatly simplify centering process, reduce centering difficult point, improve centering precision.
