It is good, various special lengthening screw taps are purchased in order to process different product neededs, special lengthening screw tap is expensive, increased enterprise
Processing cost.
Utility model content
The purpose of this utility model be to provide a kind of adaptability it is good, screw tap can will be enlarged by screw tap use range adds
Long set.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of screw tap lengthens set, and the screw tap lengthens set includes sleeve and fastening adjustment screws；Sleeve inner surface is to divide
For conical surface section and straight section, conical surface section is connected with straight section；The upper end of the sleeve outer surface corresponding with conical surface section is along the circumferential direction equal
One group of tapped through hole of even distribution, the sleeve lower end outer surface corresponding with straight section are distributed uniformly and circumferentially one group of screw thread and lead to
Hole, fastening adjustment screws are fixedly connected with sleeve by tapped through hole.
Further, the taper of the conical surface section adopts Morse's taper.
Further, the number of one group of tapped through hole that the corresponding outer surface of conical surface section is distributed uniformly and circumferentially is
Three, the number of one group of tapped through hole that the corresponding outer surface of straight section is distributed uniformly and circumferentially is three.
Further, the number of one group of tapped through hole that the corresponding outer surface of conical surface section is distributed uniformly and circumferentially is
Four, the number of one group of tapped through hole that the corresponding outer surface of straight section is distributed uniformly and circumferentially is three.
Further, a diameter of 40～60mm of the excircle of sleeve.
As a result of above-mentioned technical proposal, the technique effect that this utility model is obtained has：
Inner chamber in this utility model in sleeve is provided with the conical surface section for being connected with screw tap, and the conical surface has preferably fixed
Heart effect, it is ensured that screw tap is concentric with sleeve.The setting of the conical surface can make the silk of a sleeve and multiple different-diameter models
Cone is used cooperatively.
This utility model plug tap adopts taper fit with sleeve, can transmit certain moment of torsion, while convenient dismantle.
In the certain limit of same taper, workpiece be free to dismounting, while operationally do not interfere with using effect again.
This utility model simple structure, can be used cooperatively with the screw tap of various different-diameter models, after lengthening
Screw tap can be nearer with distance axis in processing step axial end, the screwed hole that can not be processed using regular tap.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further details to this utility model：
Embodiment 1
The utility model discloses a kind of screw tap lengthens set, the screw tap lengthens set includes sleeve 1 and fastening adjustment screws
2；To be divided into conical surface section 1-1 and straight section 1-2, conical surface section 1-1 is connected 1 interior surface of sleeve with straight section 1-2；The upper end of sleeve 1 with
The corresponding outer surface of conical surface section 1-1 is distributed uniformly and circumferentially one group of tapped through hole, and 1 lower end of sleeve is relative with straight section 1-2
The outer surface answered is distributed uniformly and circumferentially one group of tapped through hole, and the concrete structure of sleeve 1 is as shown in Figure 1, Figure 2, Figure 3 shows.Tightly
Gu adjusting screw 2 is fixedly connected with sleeve 1 by tapped through hole, concrete structure is as shown in Figure 4.
Inner chamber in this utility model in sleeve 1 is provided with conical surface section 1-1 for being connected with screw tap, and the conical surface has more preferable
Centering effect, it is ensured that screw tap 4 is concentric with sleeve 1.The setting of conical surface section 1-1 can make a sleeve 1 different from multiple
The screw tap 4 of diameter model is used cooperatively.The taper of conical surface section 1-1 preferably uses Morse's taper value, lengthens set to improve the screw tap
Versatility.Screw tap 4 adopts taper fit with sleeve 1, can transmit certain moment of torsion, easily can also dismantle.Same
In the certain limit of taper, workpiece be free to dismounting, while operationally do not interfere with using effect again.This practicality is new
One group of fastening adjustment screws 2 is respectively provided with the top and bottom of sleeve 1 in type, the number of every group of fastening adjustment screws 2 is three.
The longer screw tap 4 and tapping machine dop 3 to adapt to different-diameter model of thread segment of fastening adjustment screws 2, and fastening is adjusted
The number of section screw 2 is set to three, therefore with certain self-centering effect.
Embodiment 2
The present embodiment is the deformation to embodiment 1, and conical surface section 1-1 of sleeve 1 has self-centering effect, therefore will be with conical surface section
The number of one group of tapped through hole that 1-1 corresponding outer surface is distributed uniformly and circumferentially could be arranged to four, sleeve 1
The number of one group of tapped through hole that straight section 1-2 corresponding outer surface is distributed uniformly and circumferentially needs to be set to three, with
Ensure that the centrage of tapping machine dop 3 is concentric with the centrage of sleeve 1.
The outside diameter of this utility model middle sleeve 1 is 40～60mm.
