Description
Technical field
The utility model relates to hole processing technical field, particularly relates to the one-body molded process tool of a kind of screwed hole.
Background technology
Along with the requirement on machining accuracy in the continuous progressive double thread hole of science and technology is more and more higher, traditional Screw thread process method is the mode adopting the rear Seiko of first boring.First, use puncher, drilling operation is carried out to material, is processed into the hole of certain diameter; Afterwards, re-use first cutter, in the hole accomplished fluently, carry out tapping; Finally, use second cutter-rose reamer, carry out angle process clearly.Every sheet material processing all needs the processing successively of above-mentioned three kinds of machining hole tools, make process time long, and staff also needs to carry out tool changing operation at tool magazine, and waste time and energy, operating efficiency is low.
Utility model content
The purpose of this utility model is to provide the one-body molded process tool of a kind of screwed hole, in the process of screw, disposablely can complete punching, tapping, clear angle processing action, not need back and forth to switch cutter, operate quick, easy, increase work efficiency.
The technical solution adopted in the utility model is:
The one-body molded process tool of a kind of screwed hole, comprise handle of a knife, clear angle knife bar, screw thread processing nut arbor, the front end of handle of a knife connects clear angle knife bar, the front end connecting thread processing nut arbor of clear angle knife bar, described clear angle knife bar comprises center-pole, and centrally bar circumference surrounds the rose reamer of pyramidal structure; Described screw thread processing nut arbor comprises center drill rod, center drill rod be circumferentially provided with multiple tapping sword, and the head of center drill rod is tapered.
The rose reamer that described centrally bar circumference surrounds pyramidal structure offers angle chip area clearly.
Described multiple tapping swords are arranged on the center drill rod left and right sides, and every side arranges row, and tapping sword interval is equidistantly arranged.
Described center drill rod is provided with screw chip area.
The brill that the utility model utilizes the conical nose of the screw thread processing nut arbor of cutter to carry out bottom outlet is beaten, and can punch easily; Along with screw thread processing nut arbor go deep in hole gradually time, the two row tapping swords be circumferentially provided with of screw thread processing nut arbor also can go deep in hole gradually, in the process that whole cutter punching rotates, tapping sword starts to carry out tapping to hole internal diameter, around hole internal diameter carries out circumference processing, until whole hole internal diameter has screw thread; Afterwards, then the rose reamer that clear angle knife bar circumference surrounds pyramidal structure starts to carry out chamfering cleaning to the top in hole, and further, the chip cut away in scale removal process can be discharged along with the clear angle chip area that rose reamer is offered; This device disposablely can complete punching, tapping, clear angle processing action, does not need back and forth to switch cutter, operates quick, easy, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model.
Detailed description of the invention
As shown in Fig. 1 and 2, the utility model comprises handle of a knife 1, clear angle knife bar, screw thread processing nut arbor, handle of a knife 1 turns equipment for being arranged on brill, the front end of handle of a knife 1 connects clear angle knife bar, the front end connecting thread processing nut arbor of clear angle knife bar, described clear angle knife bar comprises center-pole 2, and centrally bar 2 circumference surrounds the rose reamer 8 of pyramidal structure, and the rose reamer 8 that centrally bar 2 circumference surrounds pyramidal structure offers angle chip area 4 clearly; Described screw thread processing nut arbor comprises center drill rod 3, center drill rod 3 be circumferentially provided with multiple tapping sword 5, multiple tapping sword 5 is arranged on the symmetrical both sides of center drill rod 3, every side arranges row, tapping sword 5 interval is equidistantly arranged, and the head of center drill rod 3 is tapered, and taper forms perforating knife 6, can complete direct punching, center drill rod 3 is provided with screw chip area 7.
The utility model cutter, when machining screw hole machined, first, utilizes the conical nose of the screw thread processing nut arbor of cutter to punch, because conical nose is equivalent to perforating knife 6, can punch easily, not need bottom outlet before processing, can direct hole milling.While punching, along with screw thread processing nut arbor go deep in hole gradually time, the two row tapping swords 5 be circumferentially provided with of screw thread processing nut arbor also can go deep in hole gradually, in the process that whole cutter punching rotates, tapping sword 5 starts to carry out tapping to hole internal diameter, around hole internal diameter carries out circumference processing, namely carries out tapping processing, until whole hole internal diameter has screw thread.In the process of tapping, can be produced some and capture the chip come, by outside screw chip area 7 tap.The size of screw processing, can require to adjust according to actual size, thus meets the screw processing of different pore size.When screw thread processing nut arbor drops to certain depth, the i.e. top of clear angle knife bar contact hole, now, the rose reamer 8 that clear angle knife bar circumference surrounds pyramidal structure starts to carry out chamfering cleaning to the top in hole, and the chip cut away in scale removal process can be discharged along with the clear angle chip area 4 that rose reamer is offered.So cutter of the present utility model is all-round cutter punching, tapping, Qing Jiao combined together, easy to use.
