Description
Technical field
The utility model is related to a kind of heat-shrinkable knife handle, more particularly to a kind of heat-shrinkable knife handle of removable cutter head.
Background technology
Heat-shrinkable knife handle is a kind of cutter holding instrument popular in recent years, and operation principle is to utilize instantaneous heated blade
The clamping section of handle makes handle of a knife aperture instantaneously become larger to be packed into and take out cutter.Heat-shrinkable knife handle has fast handling, precision height, turns round
The features such as square is big, rigidity is good, processing at a high speed, in high precision, occasion is especially outstanding.But heat-shrinkable knife handle unit price is costly, it is single
Valency is generally in members up to ten thousand etc., and among practical application, once there is cracking of cutter, cutter stub segment point will be unable to from tool-holder
Section taking-up is held, causes handle of a knife premature failure, both waste of resource or has caused no small economic loss to enterprise.
Utility model content
The technical issues of the utility model solves is to provide a kind of heat-shrinkable knife handle of removable cutter head, to solve the above-mentioned back of the body
The shortcomings that in scape technology.
The technical issues of the utility model solves is realized using following technical scheme：
A kind of heat-shrinkable knife handle of removable cutter head, including holder main body, holder main body is from left to right divided into three sections, is followed successively by knife
Have gripping section, middle transition section and main shaft gripping section, the cutter head for being internally provided with the to install milling cutter peace of the cutter holding section
Behave affectedly, main shaft installation cavity be equipped in main shaft gripping section, in the cavity that is internally provided with of middle transition section, middle transition section be equipped with
The inlet of cavity connection is equipped with the runner connected between cutter head installation cavity and cavity.
Further, the outside of the cutter holding section and main shaft gripping section is tapered, and the outside of middle transition section is in straight
Tubular, shoulder is respectively equipped in the both sides of middle transition section, and inlet is arranged between the shoulder of both sides.
Further, the inlet is equipped with plugging device, and plugging device is sunk screw.
The beneficial effects of the utility model are：
The utility model need to only remove sunk screw, high pressure liquid pressure oil be injected in cavity by inlet, in high pressure
Fracture milling cutter nubbin out of cutter head installation cavity can be taken out under the action of oil, can effectively solve to be led by milling cutter fracture
The handle of a knife of cause is scrapped and the problem of premature failure, improves the service life of heat-shrinkable knife handle, improve heat-shrinkable knife handle use it is economical
Property, in addition, can effectively prevent foreign matter from entering cavity or runner and influencing hydraulic pressure to be blocked on inlet by sunk screw
The mobility of oil.
Description of the drawings
Fig. 1 is the structure diagram of the preferred embodiment 1 of the utility model；
Fig. 2 is the front view of Fig. 1；
In figure, 1- middle transition sections, 2- cutter holding sections, 3- main shaft gripping sections, 4- inlets, 5- cavitys, 6- milling cutters, 7-
Sunk screw.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment 1, referring to Fig. 1 --- Fig. 2, a kind of heat-shrinkable knife handle of removable cutter head, including holder main body, holder main body from
It is left-to-right to be divided into three sections, be followed successively by cutter holding section 2, middle transition section 1 and main shaft gripping section 3, the cutter holding section it is interior
Portion is equipped with to install the cutter head installation cavity of milling cutter 6, main shaft installation cavity is equipped in main shaft gripping section, in middle transition section 1
Portion is equipped with cavity 5, and middle transition section 1 is equipped with the inlet 4 connected with cavity 5, is equipped between cutter head installation cavity and cavity
The runner of connection.
The outside of the cutter holding section 2 and main shaft gripping section 3 is tapered, and the outside of middle transition section 1 is in straight tube shape,
Shoulder is respectively equipped in the both sides of middle transition section 1, inlet 4 is arranged between the shoulder of both sides.
The inlet 4 is equipped with plugging device, and plugging device is sunk screw 7.
The utility model in actual use, need to only remove sunk screw 7, and by inlet 4, injection is high in cavity 5
Hydraulic fluid pressure oil, but cavity 5 is connected through runner with cutter head installation cavity, and milling cutter can will be broken so under the action of high pressure oil
Nubbin takes out out of cutter head installation cavity, is scrapped and premature failure so as to solve the handle of a knife caused by being broken milling cutter
Problem improves the service life of heat-shrinkable knife handle, improves heat-shrinkable knife handle its usage economy, in addition, passing through 7 come pairs of sunk screw
Inlet 4 carries out the mobility that closure can effectively prevent that foreign matter from entering cavity or runner influences hydraulic oil.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
