However, in a general drilling and tapping screw tap, a tapping part has two cutting edges, the service life of the screw tap is short, the processed aperture is not standard, and for drilling and tapping of solid workpieces without holes, the hole is reamed for workpieces with holes, and the design of the cutting edges is unreasonable.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the utility model provides a reaming and tapping screw tap which is suitable for performing pore diameter finishing on a workpiece which is provided with a hole and has an nonstandard pore diameter, and has the advantages of high pore diameter precision and long service life.
In order to achieve the purpose, the utility model is solved by the following technical scheme:
the utility model provides a tooth screw tap is attacked in reaming, includes the screw tap, the screw tap includes tip, reaming portion, aperture accuracy control portion, reaming and keeps away the cavity, attacks tooth portion, attack tooth and keep away cavity, stalk portion, square head, reaming portion, aperture accuracy control portion, reaming keep away the cavity, attack tooth portion, attack the surface of tooth and keep away the cavity and be formed with three chip groove, the chip groove inner wall forms the side sword, the surface of attacking tooth portion still is formed with three helical cutting edge.
Specifically, the pointed end is in a conical structure.
Specifically, the reaming part is in a circular truncated cone-shaped structure.
Specifically, the diameter of the handle part is larger than that of the tapping and avoiding hollow part.
Specifically, the chip groove is of a spiral structure.
Specifically, the tapping part is close to one end of the reaming and hollow avoiding part and is further provided with a tapping guide part.
The utility model has the beneficial effects that:
the reaming and tapping screw tap is suitable for performing aperture finishing on a workpiece which is provided with a hole and has an nonstandard aperture, is provided with the reaming part and the tapping part, can perform two processes of precise reaming and tapping simultaneously, and is provided with three spiral cutting edges, so that the aperture precision is higher, and the service life is longer.

Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1-4:
a reaming and tapping screw tap comprises a screw tap, wherein the screw tap comprises a tip 1, a reaming part 2, a hole diameter precision control part 3, a reaming and cavity avoiding part 4, a tapping part 5, a tapping and cavity avoiding part 6, a handle part 7 and a square head 8, three chip grooves 9 are formed on the surfaces of the reaming and cavity avoiding part 2, the hole diameter precision control part 3, the reaming and cavity avoiding part 4, the tapping part 5 and the tapping and cavity avoiding part 6, the chip grooves 9 are of a spiral structure, side edges 10 are formed on the inner walls of the chip grooves 9, three spiral cutting edges 11 are further formed on the surface of the tapping part 5, the stability of the screw tap in the tapping and cutting process can be improved, the reaming and tapping screw tap is not prone to deflection, the hole precision of a machined workpiece is higher, the tip 1 is inserted into the hole of the workpiece during cutting, and the hole of the workpiece is cut through the side edges 10 at the position of the reaming part 3 during high-speed rotation of the reaming and tapping screw tap so as to enlarge the hole diameter, along with constantly deepening of reaming tapping screw tap, the internal thread in hole is refined through helical cutting edge 11 at last, has increased reaming and has kept away empty portion 4, has reduced the resistance in reaming tapping screw tap reaming processing, has increased tapping and has kept away empty portion 6, has reduced the resistance in reaming tapping screw tap tapping processing, prolongs the life of reaming tapping screw tap.
Preferably, the tip 1 is of conical configuration.
Preferably, the reaming portion 2 has a circular truncated cone-shaped structure.
Preferably, the diameter of the shank 7 is greater than the diameter of the tapping recess 6.
Preferably, attack tooth portion 5 and keep away 4 one ends in the reaming and still be equipped with the tooth of attacking and lead tooth portion 51, the tooth of attacking is led tooth portion 51 and is kept away the screw thread diameter that 6 one ends in the reaming was kept away to the reaming and is less than the screw thread diameter that keeps away to 5 one ends in the tapping, and during tap processing, the tooth of attacking leads tooth portion 51 and contacts with the downthehole wall contact of work piece earlier, makes the tooth of attacking portion 5 and can detain smoothly, conveniently attacks tooth portion 5 and carry out the tapping process.
The above examples only show one embodiment of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
