The specific embodiment

The utility model comprises arbitrarily angled drill jig and two kinds of forms of five equilibrium angle drill jig.

Arbitrarily angled drill jig at first is described:

Arbitrarily angled drill jig, comprise soleplate 1 and cover plate 2, soleplate 1 is made of two identical fanning strip assemblings, fan-shaped soleplate is provided with φ 7.8 datum holes 3, being the center with datum hole 3 on the fan-shaped soleplate 1 is provided with many rows' φ 2.5 small bores 4 by different angles along radial direction, and spacing is 4 millimeters between the adjacent small bore 4.Fan-shaped soleplate 1 is divided into four classes by hole figure place preface, be marked with the classification logotype of this plate at the circular arc lateral marks of every fan-shaped soleplate 1, as RS, RS+0.5, RD, RD+0.5, represent that respectively the centre-to-centre spacing between the datum hole 3 of small bore 4 and soleplate 1 is even numbers, even numbers+0. 5, odd number, odd number+0. 5.Fan-shaped soleplate 1 centre position is provided with one by the line of demarcation 12 of datum hole 3 to the circular arc edge, generally does not use simultaneously in the hole on both sides, line of demarcation, as shown in Figure 2, by the distance ordering between small bore and the datum hole center be, 1R, 3R, 5R ... marginal right half of, 2R, 4R, 6R ... half of on a marginal left side, every row goes up that spacing is 4 millimeters between the adjacent small bore, and 1R, 2R, 3R, 4R ... small bore and the distance at datum hole center between to differ be 2 millimeters.Be provided with a circular arc ring of numbers 13 along radial direction every 20 millimeters by datum hole 3 centers on the soleplate 1, can with it determine among each row any one small bore 4 and 3 liang of pitches of holes of datum hole from.Every row's small bore 4 is provided with by datum hole 3 to the edge and be extended down to the center line 14 of circular arc end face on the soleplate 1, is used for determining the direction position in first processed hole with after the center line on the part to be processed is aimed at.The angles of per two rows between the small bores 4 all indicate angle numerical value on the soleplate 1, as shown in Figure 2, are respectively 30 °, 15 °, 15 °, (boundary is 15 °+15 °), 18 °, 12 °, 30 ° from left to right.The soleplate 1 that two block identifications are identical is that benchmark is combined with datum hole 3, and the line of demarcation 12 on the soleplate 1 is two important boundaries, forms when closing the angle and generally can not cross line of demarcation 12.Be provided with security strip 5 between two fan-shaped soleplates 1, security strip 5 is provided with chute 6, and wherein a fan-shaped soleplate 1 is fixedlyed connected with security strip 4, and the fan-shaped soleplate 1 of another piece is provided with the screw 7 that can slide in chute 6.Two soleplates 1 are that benchmark carries out relative position when changing with datum hole 3, can obtain between two rounds of two soleplates, 1 contiguous breach can obtaining 180 ° of two small bore 4 positions after 4, two soleplates of two small bores, 1 combination of any angle of spacing＞4.5 millimeter and angle≤60 ° with interior any angle.Soleplate 1 is provided with cover plate 2, and cover plate 2 constitutes by two fan-shaped, connects cover plate 2 and stationary spindle 10 by screw 9 in the datum hole 3 of soleplate 1.The utility model uses step as described below, (1) at first selects soleplate 1 classification and corresponding security strip 5, cover plate 2 and stationary spindle 10 by drawing, angle between two machining holes gets up with cover plate 2 frames, (2) during stationary spindle 10 is packed the datum hole 3 of two soleplates into, cover plate 2 and stationary spindle 10 are tightened together with screw 9.(3) security strip 5 usefulness screws 7 are fixed on the soleplate 1 gently.(4) decide the position, hole: determine the position in required hole in the small bores 4 two rows of accumulated angle, and the marker pin 15 of in the hole of the vicinity in selected hole, packing into.(5) adjustment and fastening: accumulated angle, cover plate 2 and other parts are adjusted to user mode, as will use 60 ° of angles between two soleplates 1 time, two rounds over there coincide in the hole at place, insert steady pin, treat steady pin to be taken out after fixing everywhere again.(6) check: drawing and the drill jig each several part size that assembles are come into operation after the confirmation one by one.During use, drill jig is packed into behind the part to be processed, the center line 14 in the selected hole on the drill jig is aimed at the center line on the part to be processed, determine the direction position in good processed hole, pin drill jig with hand, it is fixed on the part, and first hole depth is 3～5 millimeters under at this moment boring, and inserts steady pin by drill jig, with drill jig and part relative fixed, bore 3～5 millimeters of second hole depths again ..., the drill jig of taking away is machined to the figure paper size with the aperture.The centralized positioning datum hole of part to be processed is diversified, and what size often has just should prepare how many stationary spindles.It is many so not only to waste raw material, goes back spend a lot of man-hours, uneconomical, and the too big too much keeping difficulty of axle is not easy to carry, and uses inconvenient.For this reason the present utility model 3 methods that center, mutual the cooperating in position, hole reaches replacement φ＞30 and is the effect of any diameter axle of integer on 8 kinds " little axle " of utilization φ 3～φ 10 and the soleplate.Can be in the small bore 3 on the utility model soleplate 1 by the T type nut 16 three points centering axle 11 of packing into.According to selected soleplate 1 type, round with selected hole is a benchmark, select uniform other two rounds, again according to the size of making locating hole on the part to be processed (radius), find out a hole than this pore radius＜1.5～5 in selected every round, this center, three holes is " 3 points ", this hole site size of being found out than part to be processed locating hole difference in size what, the diameter of just packing in this hole is two times poor " little axles ", and fastening with T type nut 16.

Five equilibrium angle drill jig:

The most normal aborning what run into is uniform the part in several holes around the datum hole, and as the sub-multiple angle hole of 2,3,4,5,6,8 equal portions, the utility model has designed five equilibrium angle drill jig.As long as drill jig is installed on the part to be processed, once just can machine the little bottom outlet of several φ 2.5.Five equilibrium angle drill jig comprises soleplate 1 and cover plate 2, and soleplate 1 is made of a circular slab, and the circular foundation plate is the same with fan-shaped soleplate to have the respective classified sign, and soleplate 1 is provided with φ 7.8 datum holes 3.By fixedly sub-multiple angle is provided with along radial direction, arranging φ 2.5 small bores 4 on the circular foundation plate 1 more, spacing is 4 millimeters between every row's the small bore 4, by the distance ordering between small bore 4 and datum hole 3 centers be, 1R, 3R, 5R ... be distributed on the hisectrix, 2R, 4R, 6R ... be distributed between the hisectrix on the bisector, soleplate 1 is provided with cover plate 2, cover plate 2 is made of a circular slab, circular cover 2 is provided with five equilibrium chamfered groove 8, connect cover plate 2 and stationary spindles 10 by screw 9 in the datum hole 3 of soleplate 1, can be in the small bore 4 on the soleplate 1 by the T type nut 16 three points centering axle 11 of packing into.Soleplate 1 upper edge radial direction is provided with a circumferential ring of numbers 13 every 20 millimeters, can with it determine among each row any one small bore and datum hole two pitches of holes from, every row's small bore 3 is provided with by datum hole to the edge and be extended down to the center line 14 of circular arc end face on the soleplate 1, be used for determining the direction position in first processed hole with after the center line on the part to be processed is aimed at.
