Description

Boring prelocalization frock
Technical field
The utility model relates to a kind of boring prelocalization frock, the frock of the boring predetermination hole site that specifically to relate to hydraulic pressure, lubricating utensil machinery components and parts valve body and vertical hexahedron porous processing be benchmark with the face.
Background technology
Before main " valve body " class and the boring of vertical hexahedron multi-hole position part of hydraulic pressure, lubricating utensil machinery components and parts, the position of determining the hole is the necessary operation before the boring, and the accuracy of the position in hole directly relates to the quality of workpiece.For single-piece, small lot processing, then determine the position in hole by crossed process, the positional precision in this method hole can only reach ± 0.15mm, and the line scar appears in finished surface; If the face sealing can cause face seal leak oil phenomenon; Do not have scar if guarantee the plane, must increase boring back plain grinding operation.For in, processing in enormous quantities, adopt boring prelocalization frock, the existing boring prelocalization frock nib corresponding with the hole inlayed the drill bushing of hard material, is datum hole with one of them hole, after selecting the datum level location of a datum hole else, do the position, hole in all the other holes with rhombus Wai Yuan and hole; Drilling machine passes drill bushing brill dimple with drill bit after, remove drilling tool and carry out drilling processing again.The general frock of existing boring prelocalization frock is bored nest with the above drilling tool of two covers to a kind of valve body hole position and is decided the position, hole.Because the multiple clamping workpiece, the mutual alignment accuracy in hole is relatively poor; There is smear metal to remain on the drilling tool body during in addition owing to the brill nest, often influences valve body Working position precision quality and efficient; Simultaneously, when boring nest,, the size in drill bushing hole is comparatively fast enlarged, influence the bore position precision because of drill bit rotates friction with the drill bushing hole wall at a high speed; If the frequent drill bushing of changing then can make processing cost strengthen, also have influence on working (machining) efficiency.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing boring prelocalization frock, the utility model provides a kind of boring prelocalization frock that the mutual alignment accuracy is higher, cost is low, efficient is high of hole.
This boring prelocalization frock comprises a boxlike frock shell, boxlike frock shell is made of top board, base plate, front side board and back side panel four block plates, per two blocks of adjacent steel plates fasten as one with trip bolt and locate with alignment pin, it is characterized in that: corresponding two block plates of forming boxlike frock shell are parallel to each other, two adjacent block plates are vertical mutually, and the outer end of the trip bolt of fastening steel plate sinks in the steel plate lateral surface at place; Left end and right-hand member at boxlike frock shell are installed with left plate and right plate respectively, left plate and right plate are installed on the boxlike frock shell by bearing pin, and tighten together by the trip bolt and the boxlike frock shell of countersunk head, the outer end of the trip bolt of countersunk head sinks in the steel plate lateral surface at place.Left plate and right plate are all vertical with four block plates of forming boxlike frock shell, six block plates of forming boring prelocalization frock like this, every two adjacent block plate faces are vertical mutually, perpendicularity meets the required precision of the workpiece of being processed, per two corresponding steel plates are parallel to each other, the depth of parallelism meets the required precision of the workpiece of being processed, and the two sides of every block plate is parallel to each other, and the depth of parallelism meets the required precision of the workpiece of being processed.The rarest block plate of six block plates of boring prelocalization frock is a template, is distributing on template and the corresponding through hole of workpiece, and the mutual alignment between the through hole of every template meets the requirement of institute's processing work.Orthogonal therein three block plates are installed with the trip bolt that is used for fastening workpiece.The outer end of the trip bolt of fastening workpiece sinks in the steel plate lateral surface at place, and the inner cavity size of boring prelocalization frock is greater than the appearance and size of institute's processing work, generally greater than workpiece 2-10mm.
Above-mentioned boring prelocalization frock is characterized in that: the said trip bolt that is used for fastening workpiece is to constitute with the copper packing that is fastened on steel screwed pipe lower end by having externally threaded steel screwed pipe.
This boring prelocalization frock is disposing drift and is being used, and drift is that the lower end is the steel pole of awl point, and there is handle the upper end, and the diameter of drift and the diameter of the through hole on the template match.
This boring prelocalization frock adopts a clamping, three datum level location; Replace drill bit to draw the positioning form of nest with the drift punching out, the degree of accuracy can be controlled in ± 0.05mm; Before being adapted to all kinds of " valve body " parts and vertical hexahedron multi-hole position brill machining hole below 5 kilograms, the location of hole site; And higher efficient is arranged, easy to operate.This brill prelocalization frock is used side flygate form, is convenient to clear up each contact-making surface in the frock, and the workpiece accuracy of manufacture can be guaranteed in no dead angle.
The beneficial effect of this boring prelocalization frock is: 1, do not have the scar of line to workpiece, the precision grinding process after need not to bore is eliminated cut; 2, no drilling cuttings produces, and is convenient to cleannes in the workpiece manufacture process to guarantee machining accuracy; 3, by given precision of manufacturing process requirement, with this boring prelocalization frock, press standard operation, the mutual alignment precision in each hole can be controlled in ± 0.05 millimeter scope in; 4, clamping can be finished the punching out location in the hole of six faces, and work efficiency can be brought up to 3-6 doubly.The prelocalization of this boring simultaneously tool structure is simple, and the manufacturing process difficulty is little.
