2, length 420mm, general sinusoidal clamp jaw width is inadequate, adds that workpiece bonds, and place arbitrarily, positional precision is poor, adopts sinusoidal fixture meaningless.
3, use surface grinding machine or cutter and tool grinding machine processing, grinding force is large, does not reach required precision.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides the processing method of a kind of angular adjustment apparatus and carborundum 45 degree of speculums, to solve the problem of carborundum 45 degree of speculum processing.
Technical solution of the present utility model is as follows:
A kind of angular adjustment apparatus, feature is that this device is made up of clamping plate, supporting plate, three jack, the first bolts, described clamping plate be a bottom surface at grade, the orthogonal cylinder of cross section becomes base angle to be the integrative-structure of the cylinder composition of the right-angled trapezium of 45 ° with cross section, the inclined-plane of these clamping plate has the strip groove that is parallel to bottom surface, these clamping plate are bolted on described supporting plate by first, connect three described jack and form angle adjusting mechanism below this supporting plate.
Utilize above-mentioned angular adjustment apparatus to carry out the processing method of carborundum 45 ° of speculums, the method comprises the following steps:
1), first by carborundum 45 ° of speculums to be processed except 45 ° of inclined-planes, all the other sizes of several first utilize other simple frocks processing to put in place;
2), by carborundum 45 ° of speculums to be processed adopt sealing wax to be bonded in the strip groove on the inclined-plane of described clamping plate, make the right-angle surface of carborundum 45 ° of speculums to be processed, namely C face is perpendicular to the inclined-plane of described clamping plate.
3) right-angle surface, utilizing the carborundum 45 ° of speculums to be processed described in three-coordinates measuring machine measurement is basal plane, supporting plate described in three screw-jack triangularities being supported, surveys height error X numerical value between the plane A point of described clamping plate and B point again after adjustment jack makes the right-angle surface of described carborundum 45 ° of speculums become 135 ° with described lathe table top.
4), on the lathe table top of coordinate grinding machine tool install described angular adjustment apparatus, three jack become 3 triangles, one of them are done and finely tune up and down, make the X value that between clamping plate plane A point with B point, height error X numerical value and three-dimensional record identical.By pressing plate, support pad and the second bolt, described angular adjustment apparatus is fixedly mounted on described lathe table top, and compresses.
5), start coordinate grinding machine tool, up and down reciprocatingly, resin diamond grinding wheel inserts the inclined-plane ground in described silicon carbide mirror to coordinate grinding machine tool bistrique, i.e. D face, until completion of processing.
6) clamping plate are unloaded together with silicon carbide mirror arrive three-coordinates measuring machine again and measure, the angle value directly between survey C face and D face, when the error of this angle value and 45 degree be less than ± 5 ", enter step 8); When the error of this angle value and 45 degree be greater than ± 5 ", then enter step 7).
7) be arranged on described supporting plate by described clamping plate and silicon carbide mirror by the first bolt, according to the data recorded, the jack in the middle of adjustment, returns step 5).
8) process finishing, unloads described carborundum 45 ° of speculums from described clamping plate.
Compared with prior art, the beneficial effects of the utility model are: utilize coordinate to grind machining accuracy and the little advantage of grinding force, adopt resin-bonded skive, use the method for plugging in mill, (because workpiece bonding needs grinding force little), adopts the utility model angular adjustment apparatus, adds the cooperation of three-coordinates measuring machine, solve a difficult problem for carborundum 45 degree of speculum processing, obtain satisfied required precision.
