Description

Quick adjustable drill jig and the clamping tool

The utility model belongs to the B23Q group in International Classification of Patents.

At present, known drill jig is divided into two classes: a class is a special fixture, and it designs according to a certain specific part; Another kind of is adjustable drill jig, is at a collection of size difference and the similar part of shape and designing.Their common drawback is that versatility is poor.For shape and size difference, again little part in batches, if adopt milling machine processing, though can guarantee machining accuracy, working (machining) efficiency is low; As processing with pincers worker line, drilling machine, not only efficient is low, and precision also is difficult for guaranteeing; If the design specialized anchor clamps, not only the cycle is long, nor economical.For this reason, Nanjin Machinery Inst. has proposed polar coordinates indexing jig scheme (China Machine Press, " the Metal Cutting Machine Tool anchor clamps atlas " first volume--Universal adjustable anchor clamps, P52, standard book number 150335536).But this scheme only is applicable to the processing disc type work.Its position, hole distributes less than the aperture in 160 ° of angles of circumference, and the polar coordinates position of a drill bushing is just adjusted in every brill one hole, comprises radius vector R and polar angle α.

Task of the present utility model provides a kind of quick adjustment drill jig, by the transposing template, and all kinds of holes that distribute arbitrarily on can processing work.

In addition, further provide drill jig, utilize above-mentioned quick adjustment drill jig, this drill jig can processing work on than the various holes of above-mentioned wider and any distribution.By the template on the transposing drill jig, to adapt to the hole of different five equilibriums on the workpiece.

Task is achieved in that and at first designs the quick adjustment drill jig.It is made up of substrate, change, template, rotatable parts (gear or worm and gear or tooth bar) at least.Holding the change that template is housed with one heart in the circular port of substrate.One side of substrate is equipped with the rotating shaft of vertically passing this substrate.Gear is equipped with in the lower end of rotating shaft, and the sector rack below being fixed on change (or gear) is meshed.Template by at least one, radial distribution and divide equally the slide block guide rail groove of circumference and its external circumference form.With on the slide block that adjusting rod links to each other drill bushing is housed.Rotary regulating lever can be regulated R; Rotating shaft utilizes engagement, can regulate α.Said R and α, all can read from corresponding graduation apparatus.

Utilize the drill jig of above-mentioned quick adjustment drill jig, two kinds of basic schemes are arranged: first kind of scheme be, drill jig can lifting, and workpiece is done laterally and lengthwise movement.Second kind of scheme is the workpiece lifting, and drill jig is done laterally and lengthwise movement.Two kinds of schemes, all be drill jig last, workpiece is down, all have vertically, laterally, moving component and pillar parts and clamp body parts longitudinally.

According to the quick adjustment drill jig that such scheme is made, both can process hole uniform on the same circumference, also can process α is identical, R is different hole or all different hole of α, R, by the bar number of the slide block guide rail groove on the template, make series mask.According to the distribution of workpiece hole, can select and quick transposing template corresponding, make it to adapt to the hole class processing of various workpiece.When guide-track groove had only one, all right machining hole heart was by hole or the hole and the very little hole of initial point distance of polar coordinates initial point (limit).

In the accompanying drawing, Fig. 1 is the drill jig schematic diagram of three guide-track grooves in the utility model.Fig. 2 is an alternative plan drill jig schematic diagram.Fig. 3 is the first scheme drill jig schematic diagram.Fig. 4,5,6,8 is respectively A-A, B-B, C-C schematic diagram and the D-D rotation schematic diagram of Fig. 1.Fig. 7 is that the K of Fig. 5 is to schematic diagram.

Below in conjunction with accompanying drawing, embodiment is described.

At first, the quick adjustment drill jig is described.In the circular port of substrate ［ 1 ］, accommodate the change ［ 21 ］ of fixing template ［ 20 ］ with one heart.One side of substrate ［ 1 ］ has the rotating shaft ［ 26 ］ of vertically passing this substrate ［ 1 ］.Rotating shaft ［ 26 ］ lower end is fixed with gear ［ 24 ］.The sector rack ［ 22 ］ (or gear) of this gear ［ 24 ］ below being fixed in change ［ 21 ］ is meshed.Template ［ 20 ］ by at least one, slide block guide rail groove ［ a ］ and its circumscribed circle of radial equipartition form.The slide block ［ 15 ］ of quick change drill bushing ［ 10 ］ is housed, rotatable adjusting rod ［ 3 ］ and go up advance and retreat (promptly regulating R) at guide-track groove ［ a ］.Rotate above-mentioned rotating shaft ［ 26 ］, then drive template ［ 20 ］ and rotate, thereby regulate α.

R can read from being fixed in scale ［ 7 ］ on the guide-track groove ［ a ］, and then can also read in detail from the dial ［ 4 ］ that is fixed on the adjusting rod ［ 3 ］.α can read from the angle coarse scale bar ［ 6 ］ that is fixed in substrate ［ 1 ］ circular port periphery, and then reads in detail from the scale plate ［ 25 ］ that is fixed in rotating shaft ［ 26 ］ upper end.

In order to prevent dust and metal fillings, can on change ［ 21 ］, add sealing ring ［ 13 ］; On adjusting rod ［ 3 ］, install dust cover ［ 11 ］ additional; Under gear ［ 22 ］, ［ 24 ］, install sealing ring ［ 23 ］ additional; On slide block ［ 15 ］, install sealing plate ［ 19 ］ additional.

Lining ［ 9 ］, rank shape screws ［ 8 ］, quick change drill bushing ［ 10 ］, pressing plate ［ 16 ］, adjusting rod nut ［ 14 ］, sealing plate ［ 19 ］, cover plate ［ 18 ］, T type screw ［ 17 ］ are housed on the slide block ［ 15 ］.Lining ［ 9 ］ closely cooperates with slide block ［ 15 ］, quick change drill bushing ［ 10 ］ and lining ［ 9 ］ matched in clearance.Rank shape screws ［ 8 ］ directly are contained on the slide block ［ 15 ］.Neither allow quick change drill bushing ［ 10 ］ rotate, do not allow it break away from lining ［ 9 ］ again.Pressing plate ［ 16 ］ is fixed in slide block ［ 15 ］ lower surface, and it is slided in guide-track groove ［ a ］ flexibly.Slide block ［ 15 ］ cooperates with guide-track groove ［ a ］ tapering.T shape screw ［ 17 ］ is used for slide block ［ 15 ］ is fixed in guide-track groove ［ a ］.One end band nut ［ 14 ］ of adjusting rod ［ 3 ］ links to each other with slide block ［ 15 ］ by screw, pin, and the end enters its bearing ［ 2 ］; The other end passes the support ［ 5 ］ that is fixed on substrate ［ 1 ］ the circular port periphery, and the end is with packing ring, round nut, dial ［ 4 ］.Change ［ 21 ］ and substrate ［ 1 ］ taper fit, after change ［ 21 ］ goes to required angle, fixing with hook-shaped screw ［ 12 ］.Quick change drill bushing ［ 10 ］ center is to the distance of initial point, and promptly the indication other method of R is for to load onto vernier on slide block ［ 15 ］, cooperate with scale ［ 7 ］ read (the same slide measure of principle).The control method of α can also rotate change ［ 21 ］ by worm gear, worm screw and reach except above-mentioned points; Or reach by the sector rack (or gear) that is contained in the tooth bar on the substrate ［ 1 ］ and be contained in change ［ 21 ］.

Here will state, quick change drill bushing ［ 10 ］ can be changed fast, and to adapt to the variation of aperture (φ d), template ［ 20 ］ also can be passed through screw ［ 28 ］ transposing fast with alignment pin ［ 29 ］.Because template ［ 20 ］ becomes series by the bar number of the guide-track groove on it ［ a ］.Echo mutually with the distribution of machining hole position by the transposing of template ［ 20 ］.

The drill jig of being furnished with above-mentioned quick adjustment drill jig ［ 32 ］, divide two big classes, the first kind is a drill jig ［ 32 ］ and move both vertically parts ［ 38 ］ together, and workpiece ［ 34 ］ can move and fixing at grade with lengthwise movement parts ［ 39 ］ transverse movement parts ［ 40 ］.Second class is that the transverse movement parts ［ 36 ］ at drill jig ［ 32 ］ place also can move with lengthwise movement parts ［ 35 ］ and fix at grade, and workpiece ［ 34 ］ is with the parts that move both vertically ［ 33 ］ lifting.They all have pillar parts ［ 30 ］, ［ 37 ］ and clamp body parts ［ 31 ］［ 41 ］.Clearly this class drill jig is not only at three dimensions (X, Y, Z), and can quick adjustment at polar coordinates (R, α).As for the adjusting of X, Y, Z, as long as task proposes, concrete structure is not difficult to implement.
