Description

Sleeve screw tap
Technical field
The utility model relates to a kind of structure of set tap, particularly can with the matching used sleeve screw tap of ratchet spanner, belong to cutting element technical field.
Background technology
The kind of set tap is a lot, conventionally, by conehead working portion and taper shank and taper shank end is convenient to the fixing quadrangle body of screw tap or hexagon end of body forms, when use, need to use spanner that square or hexagonal end are clamped and rotate screw tap, reach the object of tapping, time-consuming, effort, efficiency is not high, and some special processing environments cannot be used by the restriction of spanner handle.
Utility model content
The purpose of this utility model is exactly the needs for meeting market, and a kind of sleeve screw tap and manufacture method thereof are provided, and this screw tap can be realized Fast Installation and the use in operation, increases work efficiency, and reduces labour intensity.
The purpose of this utility model is to be achieved through the following technical solutions, sleeve screw tap, comprise the square body of conehead, taper shank and taper shank end, it is characterized in that, the end face of described square body is provided with the driving hole of square opening or hexagonal hole, and described square opening is square hole, and every length of side of square opening is 9.8mm, hole depth 11.5mm, hole wall 5.5mm depth is provided with draw-in groove; Described hexagonal hole is regular hexagon hole, and the inscribed circle diameter of hexagonal hole is 9.5mm, hole depth 11.5mm, and hole wall 5.5mm depth is provided with draw-in groove.
Described draw-in groove is arc groove, and the R of arc groove is 3mm.
Described square body is regular hexagon body, and the limit of regular hexagon body and angle are corresponding respectively with described hexagonal hole limit and angle.
Described square hole has an opposite side parallel with an opposite side of described regular hexagon body.
The conehead end of sleeve screw tap and driving hole bottom arrange centre bore 6.
The utility model is scientific and reasonable for structure, manufactures easily, easy to use.Utilize quick change ratchet spanner can realize fast the conversion of the multiple screw tap in operation, increase work efficiency, reduce work and force the way across.
When use, ratchet spanner tetragonal body latch or hexahedron latch (with the driving hole coupling of square hole or hexagonal hole) are aimed to the driving hole of the taper shank end of screw tap, pinning ratchet spanner locking button inserts, after release button auto lock, realize fast and connecting, screw tap and spanner are connected as a single entity, tapping or return when tooth, can, by stirring ratchet spanner head direction control slide block, realize the left-handed and dextrorotation of screw tap.Special narrow processing environment, uses ratchet spanner to be greater than 15 degree at permission rotation angle range and realizes tapping and return tooth, has solved the irrealizable problem of other spanners.Outside, screw tap tail place (taper shank end outside) is hexagon body, also can use screw tap special spanner or other kind spanners to carry out tapping and return tooth, has realized the wildcard of screw tap occupation mode.

Detailed description of the invention
Sleeve screw tap, is made up of the square body of conehead 1, taper shank 2 and taper shank end, and material is M6542.The end face of square body is provided with driving hole, and driving hole is square hole 3 or regular hexagon hole 4.Every length of side of square hole is 9.8mm, hole depth 11.5mm, and the inscribed circle diameter in regular hexagon hole is 9.5mm, hole depth 11.5mm.On the hole wall of driving hole 5.5mm depth, establish draw-in groove 5, draw-in groove is arc groove, and the R of arc groove is 3mm.The square body of taper shank end is regular hexagon body, and the limit of regular hexagon body and angle are corresponding respectively with limit, described regular hexagon hole and angle.Square hole has an opposite side parallel with an opposite side of regular hexagon body.The conehead end of sleeve screw tap and driving hole bottom arrange centre bore 6.
The manufacturing step of sleeve screw tap:
1) blanking: the section material of blanking diameter 24 mm, length 75 mm, material M6542;
2) adopt lathe in machining to become bar in the section material of step 1), clamp bar one end car bar other end end face and see light, at car light end face centre drill mesopore, median pore diameter 9 mm, the degree of depth 11 mm;
3) by step 2) bar that Vehicle Processing is good puts into power frequency heating furnace, be heated to 950 degree ~ 1180 degree, after thoroughly burning, put into mould forging forming workpiece, workpiece end face mesopore forging forming quadrate or hexagonal driving hole, the length of side of square hole is 9.8 mm, dark 12.5 mm; The inscribed circle diameter of hexagonal hole is 9.5 mm, dark 12.5 mm; It is taper shank that workpiece has one end of driving hole, and the other end is conehead working portion;
4) workpiece of step 3) forging forming is put into annealing furnace, spend ~ 950 degree of temperature 900, with reference to existing high-speed cutter annealing process annealing;
5) the taper shank end of step 4) annealing workpiece is put into digital control lathe clamper, conehead end holds out against, turner part outside diameter 22.30 mm;
6) by the workpiece of step 5) Vehicle Processing, clamp conehead end car taper shank end face, ensure the driving hole degree of depth 11.5 mm, on driving hole hole wall 5.5mm depth hole wall, cutting arc groove is draw-in groove, the R of arc groove is 3mm;
7) by the workpiece after step 6) processing, at driving hole hole subdrilling centre bore, center-hole diameter 1.5mm, center hole depth 3.15mm; Clamp the flat conehead end of taper shank one end car end face, Workpiece length 71.4 mm, at conehead end end face drill centers, center-hole diameter 1.5 mm, dark 3.15 mm; Double Tops workpiece two ends turning is to excircle of workpiece diameter 21.30 mm screw tap blanks;
8) according to screw tap conventional machining method, outside screw tap blank taper shank end milling is become to hexagon, hexagon inscribed circle diameter is 19.5 mm; By the conehead working portion milling screw tap chip pocket quartering of screw tap blank, then carry out quenching heat treatment, HRC62 ~ 64 degree, then grind one's teeth in sleep: dress top mill spiral shell screw thread 14X1.25, dress top thread grinding 17X1.25, opens 17X1.25 cutting mouthful, makes sleeve screw tap;
9) step 8) is made to the inspection of sleeve screw tap, packaging, warehouse-in.
