Background technology
Vertical machining centre processing radial hole is adopted in the boring of traditional bearing pin, though can ensure the quality of products, the equipment purchase cost is high, and working (machining) efficiency is low, and percent defective is high, operates time-consumingly, and labour intensity is big, and is dangerous.
Summary of the invention
The technical problem that the present invention will solve is to overcome existing defective, and a kind of bearing pin drilling tool mould is provided, and can raise the efficiency, and reduces labour intensity, increases security, improves yield rate.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of bearing pin drilling tool of the present invention mould; Comprise base, V-block, model drilling body, drill bushing, positive stop, axial location seat, pressing plate, dive key, back-up block, support bar, stud, spring; Said base is a rectangular structure, and right ends is laid model drilling body; Said model drilling body is divided into and comprises left model drilling body and right model drilling body, and all there are three drill bushings the model drilling body upper end; Positive stop is equipped with in said axial location seat Guan County; Said V-block is four, comprises each two of outer V-block and interior V-blocks; Said back-up block comprises big back-up block and little back-up block, and big back-up block is installed on the outer V-block, and little back-up block is installed on the interior V-block; Said support bar is two, all is fixed between left model drilling body and the right model drilling body; Said pressing plate is two, and pressing plate is a cuboid, and an end has strip boring; Said stud is two, passes the boring of two pressing plates, one end respectively and fixes with nut, and one section stud between base and the pressing plate is set with spring, and whole stud and spring are used to support pressing plate; Said dive key is installed in axial location seat and four V-block bottom surfaces.
Further, the installed surface of said base is fluted, and axial location seat and four V-block underrun dive keys are placed on the groove.
Further, said V-block all can be fixed on the base according to the requirement of workpiece through four pieces of nuts.
Further, said axial location seat can be fixed on the base according to the requirement of workpiece through two pieces of nuts.
Further, said drill bushing is fixing specification not, can require to change according to processing parts.
Further, the external diameter of said stud is less than the internal diameter of pressing plate boring.
Further, said big back-up block is four holes, is fixed on the outer V-block with four pieces of screws.
Further, said little back-up block is two holes, is fixed on the interior V-block with two pieces of screws.
A kind of bearing pin drilling tool of the present invention mould, to bearing pin product aperture, adjustable die, converted products can be raised the efficiency, and reduces labour intensity, increases security, improves yield rate.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a front schematic view of the present invention;
Fig. 3 is a vertical view of the present invention;
Fig. 4 is a side schematic view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Like Fig. 1,2,3, shown in 4, base 1 is a rectangular structure, and left model drilling body 6 and right model drilling body 4 are laid in two ends, and has on the base and be parallel to long groove.Left side model drilling body 6 and right model drilling body 4, all there are three drill bushings 5 the model drilling body upper end.Axial location seat 8 is fixed on base 1 left side, and left drill jig 6 bodies below is equipped with positive stop 7 on the axial location seat 8.V-block is four; Comprise outer V-block 2 and interior V-block 3 each two; Outer V-block 2, interior V-block 3 all can be fixed in base 1 groove optional position according to the requirement of workpiece with axial location seat 8; Dive key 10 is installed in axial location seat 8, outer V-block 2 and interior V-block 3 bottom surfaces, and axial location seat 8 is placed on the groove with interior V-block 3 underrun dive keys 10 with outer V-block 2.Big back-up block 11 is installed on the outer V-block 2, and ramuscule bracer 12 is installed on 3 of the interior V-types.Two support bars 13 all are fixed between left model drilling body 6 and the right model drilling body 4.Two block pressur plates 9 are cuboid and an end has strip boring; Two studs 14 pass the boring of two pressing plates, 9 one ends respectively and fix with nut; One section stud 14 between base 1 and the pressing plate 9 is set with spring 15, and whole stud 14 is used to support pressing plate 9 with spring 15.
When the needs processing parts; Be processed as example with needs left side model drilling body 6; Workpiece is positioned on outer V-block 2 and the interior V-block 3, and according to the position of the required boring of workpiece, in the position of the good axial location seat of groove adjusted 8, outer V-block 2 and interior V-block 3 and fixing; The nut of backing out simultaneously on the stud 14 is also fixed the purpose of workpiece to reach pressing plate 9, holes on workpiece through left model drilling body 6 selected drill bushings 5 at last.
A kind of bearing pin drilling tool of the present invention mould, to bearing pin product aperture, adjustable die, converted products can be raised the efficiency, and reduces labour intensity, increases security, improves yield rate.
The above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
