Description
Technical field
The utility model belongs to screw thread process technical field, attacks mantle fiber more particularly to a kind of multifunctional safety is self-centering
Device.
Background technique
Currently, screwing tool mainly has screw tap and plate when passing through machine tooling small size screw thread (M22 or less)
Tooth, for processing small size internal screw thread, screw die adds for processing small size external screw thread for clamping screw tap progress internal screw thread screw tap
The auxiliary tool of work is windeisen, and also known as " tap wrench ", the auxiliary tool that outer bolt processing is carried out for clamping screw die is plate
Tooth spanner, also known as " die handle ", and windeisen and die-stock are independent from each other two kinds of spanners always, that is,
It says, when needing while using tap and die progress internal and external threads processing, it is also necessary to prepare windeisen and screw die simultaneously
, this also necessarily will increase auxiliary spanner in the quantity for virtually increasing auxiliary tool, and for tool manufacturing enterprise
The manufacturing cost of assistant engineer's tool.
Further more, traditional windeisen and die-stock is felt relieved by tailstock tool center hole, and workpiece is by master
Axis chuck carries out clamping centering, but factors are influenced by workpiece outer diameter is lack of standardization etc., after clamping workpiece, work
Part axle center and machine tool chief axis axle center are easy to appear off-set phenomenon, tapping occur so as to cause workpiece and attack partially or cover the inclined phenomenon of silk braid,
It also will cause screw tap or screw die fracture damage when serious, while causing part rejection.
In addition, when carrying out internal thread machining using traditional windeisen clamping screw tap, and traditional die-stock is utilized to press from both sides
When holding screw die progress outer bolt processing, the rotating spanner progress screw thread process on lathe manually is needed, not only labor intensity of workers
Greatly, and screw processing quality is not easy to guarantee, can be damaged toward contact because of screw tap caused by undue force or screw die, in particular with silk
When boring processing blind hole screw thread, more wants especially careful, because easily screw tap fractures in processing blind hole screw thread, while causing part
It scraps.
