Abstract

The utility model provides a kind of nonstandard threading tool, including a cutter head, is made of two frustums of a cone and the cylinder between two frustums of a cone, and the bottom surface of two frustums of a cone is overlapped with two bottom surfaces of the cylinder to form cutter head respectively；Further include a main body pole, be used as handle, the cutter head is located at the end of the main body pole.This nonstandard threading tool, it is simple in structure, therefore be simple to manufacture, manufacturing time is short, and manufacturing cost is low, and processing rigidity is strong, meets processed surface smoothness and rigidity is good, reduce the fraction defective of later process, the accessory size produced and processed out is stablized.

Description

Nonstandard threading tool

Technical field

The utility model is related to field of machining more particularly to a kind of nonstandard threading tools.

Background technology

Mechanical processing refers to the process of being changed to the appearance and size or performance of workpiece by a kind of mechanical equipment.By adding Difference in work mode can be divided into machining and pressure processing.

In the cutting process, cutter is usually used, cutter at high speeds is rotated and needs to cut place close to object, to make Product is machined to required shape.General cutter is all industry-standard sizes and monolithic construction, and cannot widely meet makes With, and the manufacturing cycle is long, manufacturing process replicates, fraction defective is high, manufacturing cost is high.

Utility model content

The utility model provides a kind of nonstandard threading tool, for solving the above problems.

In order to achieve the above objectives, the utility model provides a kind of nonstandard threading tool, including

One cutter head, by two frustums of a cone and the cylinder integrated molding between two frustums of a cone, two frustums of a cone Bottom surface respectively with two bottom surfaces of the cylinder overlap to form cutter head；

One main body pole, is used as handle, and the cutter head is located at the end of the main body pole.

Preferably, described two frustums of a cone are respectively defined as first frustum of a cone and second frustum of a cone, second circular cone The upper bottom surface of platform is overlapped with the end of the main body pole.

Preferably, the side of first frustum of a cone and bottom surface angle are 30 °, the side and bottom of second frustum of a cone Face angle is 10 °.

Preferably, the height of second frustum of a cone is less than the height of first frustum of a cone.

Preferably, the pole is divided into two coaxial sections, the radius close to a section of the cutter head is less than far from described The radius of one section of cutter head.

Compared with prior art, the utility model has the beneficial effects that：The utility model provides a kind of nonstandard threading tool, including

One cutter head is made of, the bottom of two frustums of a cone two frustums of a cone and the cylinder between two frustums of a cone Face is overlapped with two bottom surfaces of the cylinder to form cutter head respectively；

This nonstandard threading tool, it is simple in structure, therefore be simple to manufacture, manufacturing time is short, and manufacturing cost is low, and processing rigidity is strong, Meet processed surface smoothness and good, the fraction defective of process after reduction of rigidity, the accessory size produced and processed out are stablized.

Description of the drawings

Fig. 1 is nonstandard thread cutter structure schematic diagram provided by the utility model；

Fig. 2 be Fig. 1 rotate be vertical state to main body pole after enlarged drawing at A.

In figure：1- cutter heads, first frustums of a cone of 11-, 12- cylinders, second frustums of a cone of 13-, 2- main body poles.

Specific implementation mode

To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings to this The specific implementation mode of utility model is described in detail.

Fig. 1 to Fig. 2 is please referred to, the utility model provides a kind of nonstandard threading tool, including

One cutter head 1,12 integrated molding of cylinder by two frustums of a cone and between two frustums of a cone, two circular cones The bottom surface of platform is overlapped with two bottom surfaces of the cylinder 12 to form cutter head 1 respectively；

One main body pole 2, is used as handle, and the cutter head 1 is located at the end of the main body pole 2.

Specifically, described two frustums of a cone are respectively defined as first frustum of a cone 11 and second frustum of a cone 13, second circle The upper bottom surface of frustum 13 is overlapped with the end of the main body pole 2.The height of second frustum of a cone 13 is less than described first and justifies The height of frustum 11.The section of two frustums of a cone is all isosceles trapezoid, side and the bottom surface angle of first frustum of a cone 11 It it is 30 °, side and the bottom surface angle of second frustum of a cone 13 are 10 °.

The basal diameter of cylinder 12 is 12mm, and the height of entire cutter head 1 is 3.04mm, and the height of first frustum of a cone 11 is 1.38mm, cylinder 12 form rounded corner, rounded corner radius in place of being connected with first frustum of a cone 11 and second frustum of a cone 13 For 0.2mm.

Preferably, the main body pole 2 is divided to for two coaxial sections, the radius close to a section of the cutter head 1 is less than far The radius of a section from the cutter head 1 so that the section intensity far from the cutter head 1 increases, and increases mounting area.

Obviously, it is new without departing from this practicality can to carry out utility model various modification and variations by those skilled in the art The spirit and scope of type.If these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology Within the scope of, then the utility model is also intended to including these modification and variations.
