Abstract
The utility model belongs to blind threaded technical field, proposes a kind of blind hole chasing bar, including motor；It is provided with rotation axis on motor, disk is provided in rotation axis, is provided with threading tool on disk；Following several baneful influences can be occurred by solving existing screw tap and being once broken: although scrap of the product and product are not scrapped, special process mode being needed to take out fracture screw tap, expended a large amount of human and material resources, seriously affect the technical problems such as manufacturing schedule.
Description
Technical field
The utility model belongs to blind threaded technical field, is related to a kind of blind hole chasing bar.
Background technique
We can be commonly encountered various drawings, various parts in production, and be passed through in part process
It is commonly encountered requirement of the product to accuracy of screw machining.
The classification of screw thread process mode is roughly divided into: it is through hole whorl, blind threaded, blind threaded and include two kinds of patterns:
Thread Pilot hole is general counterbore, screw-threaded counterbore bottom belt escape.
Above several situations, in processing blind hole screw thread and without escape, and product has the depth of thread after processing
In the case where exact requirements, screw tap phenomenon of rupture can occur often.
Screw tap, which is once broken, can occur following several baneful influences: although scrap of the product and product are not scrapped, need
Special process mode takes out fracture screw tap, expends a large amount of human and material resources, seriously affects the technical problems such as manufacturing schedule.
Utility model content
The utility model proposes a kind of blind hole chasing bars, solve above-mentioned technical problem.
The technical solution of the utility model is achieved in that
A kind of blind hole chasing bar, comprising:
Motor；It is provided with rotation axis on the motor, disk is provided in the rotation axis, is provided with and attacks on the disk
Silk cutter.
As further technical solution, the threading tool includes knife handle and screw thread threading tool, and the knife handle is connected to institute
Disk is stated, the screw thread threading tool is arranged in the knife handle end.
As further technical solution, the knife handle is cylindric, the axis of the axis of the knife handle and the disk
In parallel.
As further technical solution, the side of the knife handle is arranged in the screw thread threading tool.
Compared with prior art, the utility model has the beneficial effect that
1, in the utility model, it is provided with rotation axis on motor, disk is provided in rotation axis, is provided with tapping on disk
Cutter, motor provide power for rotation axis, and rotation axis rotation drives disc rotary, and then threading tool is driven to move in a circle.
2, in the utility model, threading tool includes knife handle and screw thread threading tool, and knife handle is connected to disk, the setting of screw thread threading tool
In knife handle end and the side of knife handle is arranged in screw thread threading tool, and screw thread threading tool only goes out to process the screw thread of a part every time, passes through circle
The processing of whole screw threads is completed in the feeding and rotation of disk.
3, in the utility model, knife handle be it is cylindric, in process, knife handle is simultaneously not filled by full blind hole, process inner hole
Have a large amount of vacant, convenient for the discharge of steel cuttings, and screw tap will not be broken；The axis of knife handle and the axis of disk are parallel, knife handle
It is not located on the axis of disk and makes rotating motion, but the axis around disk moves in a circle, and carries out spiral cutting processing；
This circular motion overcomes technology prejudice.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is threading tool partial enlarged view in the utility model；
Fig. 3 is disk schematic cross-section in the utility model；
Fig. 4 is counterbore partial enlarged view in the utility model；
Fig. 5 is knife handle end partial enlarged view in the utility model.
In figure: 1- motor, 2- rotation axis, 3- disk, 4- threading tool, 41- knife handle, 42- screw thread threading tool.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the utility model proposes a kind of blind hole chasing bars, comprising:
Motor 1；It is provided with rotation axis 2 on motor 1, disk 3 is provided in rotation axis 2, is provided with threading tool on disk 3
4。
In the present embodiment, it is provided with rotation axis 2 on motor 1, disk 3 is provided in rotation axis 2, is provided with and attacks on disk 3
Silk cutter 4, motor 1 are that rotation axis 2 provides power, and the rotation of rotation axis 2 drives disk 3 to rotate, and then threading tool 4 is driven to do circle
Zhou Yundong.
Further, threading tool 4 includes knife handle 41 and screw thread threading tool 42, and knife handle 41 is connected to disk 3, and screw thread threading tool 42 is set
It sets in 41 end of knife handle and the side of knife handle 41 is arranged in screw thread threading tool 42.
In the present embodiment, threading tool 4 includes knife handle 41 and screw thread threading tool 42, and knife handle 41 is connected to disk 3, screw thread threading tool
42 are arranged in 41 end of knife handle and screw thread threading tool 42 is arranged in the side of knife handle 41, and screw thread threading tool 42 only goes out to process a part every time
Screw thread, the processing of whole screw threads is completed by the feeding of disk 3 and rotation.
Further, knife handle 41 is cylindric, and the axis of knife handle 41 is parallel with the axis of disk 3.
In the present embodiment, knife handle 41 be it is cylindric, in process, knife handle 41 is simultaneously not filled by full blind hole, process inner hole
Have a large amount of vacant, convenient for the discharge of steel cuttings, and screw tap will not be broken；The axis of knife handle 41 is parallel with the axis of disk 3, knife
Handle 41 is not located on the axis of disk 3 and makes rotating motion, but the axis around disk 3 moves in a circle, and carries out spiral and cuts
Cut processing；This circular motion overcomes technology prejudice.
Further, threading tool 4 can adjust position on disk 3, and then adjust the axis of knife handle 41 to the axis of disk 3
The distance between line changes the radius that threading tool 4 moves in a circle, to adapt to different size of blind hole machining.
Further, the counterbore that distance is different between several groups and the center of circle of disk 3 is provided on disk 3, in each counterbore
It is respectively provided with there are two spring, is respectively connected with fixture block on each spring；It is opened on knife handle 41 there are two groove, groove and fixture block match
It closes, knife handle 41 can be fixedly mounted in counterbore.
In the present embodiment, different counterbores can change the axis of knife handle 41 to the distance between the axis of disk 3, in turn
Change the radius that threading tool 4 moves in a circle, to process different size of blind hole, there is better adaptability.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
