Abstract
The invention relates to an 80-degree non-sealing pipe thread tap. Including screw tap handle and screw tap working part, screw tap handle and screw tap working part are two solitary individualities, screw tap working part includes tapping screw thread and chip groove, the tapping screw thread is 80 degrees non-sealing pipe threads, the chip groove is the axial straight flute, and screw tap working part rear end axle center department is equipped with the recess, the recess is positive quadrangle, the front end of screw tap handle is established to be the positive quadrangular shape with recess matched with, the rear end of screw tap handle is positive right hexagonal prism shape, has seted up three locating hole on the positive right hexagonal prism shape side of screw tap handle, and three locating hole each other becomes 120 degrees distributions on positive straight hexagonal prism face. The screw tap clamping device is simple in structure, when the screw tap working part is damaged, only the screw tap working part needs to be replaced independently, resource waste is reduced, materials are saved, the screw tap is convenient to assemble, the screw tap is stable in clamping state, and therefore machining precision is guaranteed.
Description
Technical Field
The invention relates to a thread tap of an 80-degree non-sealing pipe, and belongs to the technical field of hardware tools.
Background
A screw tap is a common hardware tool, and is generally used for machining cylindrical or conical internal threads, also called a screw tap, on a workpiece. The tap can be classified into a spiral tap and a straight-edge tap according to the shape, and can be classified into a hand tap and a machine tap according to the use environment. At present, the tap handle and the tap working part of screw tap form by integrated into one piece, if the damage appears in the tap working part, then whole screw tap just will be scrapped, just increased the cost of enterprise in the intangible like this, cause the data extravagant, the clamping stability at screw tap centre gripping position is the important factor that influences the machining precision, traditional tap handle is often processed into optical axis handle or right angle handle, the easy appearance of skidding of optical axis handle screw tap in the processing, the phenomenon of following the commentaries on classics, axial and axial stability can all be relatively poor, right angle handle screw tap circumference centre gripping is comparatively stable, the phenomenon of skidding or following the commentaries on classics can not appear, but the phenomenon that the abnormal motion and rocking can still appear in the axial of right angle handle screw tap, the machining precision improves.
Disclosure of Invention
Aiming at the defects, the invention aims to provide the 80-degree non-sealing pipe thread tap which is simple in structure, convenient and quick to assemble, capable of reducing enterprise cost and resource waste, stable in tap clamping state and capable of ensuring machining precision.
Therefore, the technical scheme adopted by the invention is as follows:
including screw tap handle and screw tap working part, screw tap handle and screw tap working part are two solitary individualities, screw tap working part includes tapping screw thread and chip groove, the tapping screw thread is 80 degrees non-sealing pipe threads, the chip groove is the axial straight flute, and screw tap working part rear end axle center department is equipped with the recess, the recess is positive quadrangle, the front end of screw tap handle is established to be the positive quadrangular shape with recess matched with, the rear end of screw tap handle is positive right hexagonal prism shape, has seted up three locating hole on the positive right hexagonal prism shape side of screw tap handle, and three locating hole each other becomes 120 degrees distributions on positive straight hexagonal prism face.
As a further improvement of the technical scheme, the tap handle is made of a magnetic alloy material.
As a further improvement of the technical scheme, the outer surface of the tap working part is provided with a boron nitride hard wear-resistant coating.
As a further improvement of the technical scheme, the thickness of the boron nitride hard wear-resistant coating is 25 mm.
As a further improvement of the technical scheme, the positioning hole is a flat-bottom blind hole with a chamfer at the hole opening.
The invention has the advantages that:
the screw tap clamping device is simple in structure, when the screw tap working part is damaged, only the screw tap working part needs to be replaced independently, resource waste is reduced, materials are saved, the screw tap is convenient to assemble, the screw tap is stable in clamping state, and therefore machining precision is guaranteed.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a cross-sectional view a-a of fig. 1.
In the figure, 1 is a tap shank, 2 is a tap working portion, 3 is a groove, and 4 is a positioning hole.
Detailed Description
The 80-degree non-sealing pipe thread tap comprises a tap handle 1 and a tap working part 2, the tap handle 1 and the tap working part 2 are two independent individuals, the tap working part 2 comprises a tapping thread and a chip removal groove, the tapping thread is the 80-degree non-sealing pipe thread, the chip removal groove is an axial straight groove, a groove 3 is arranged at the axle center of the rear end of the tap working part 2, the groove 3 is a regular quadrangle, the front end of the tap handle 1 is arranged in a regular quadrangular prism shape matched with the groove 3, the rear end of the tap handle 1 is a regular hexagonal prism shape, three positioning holes 4 are formed in the side face of the regular hexagonal prism of the tap handle 1, and the three positioning holes 4 are mutually distributed at 120 degrees on the regular hexagonal prism face.
As a further improvement of the above technical solution, the tap shank 1 is made of a magnetic alloy material.
As a further improvement of the technical scheme, the outer surface of the tap working part 2 is provided with a boron nitride hard wear-resistant coating.
As a further improvement of the technical scheme, the thickness of the boron nitride hard wear-resistant coating is 25 mm.
As a further improvement of the technical scheme, the positioning hole 4 is a flat-bottomed blind hole with a chamfered hole.
