Description
Technical field
The present invention relates to machine tool field, more particularly to a kind of elastic circlip and utilization with safety lock structure should
The tool fixing structure of jump ring fixed cutting tool.
Background technology
Elastic circlip is also known as elastic collet chuck or collet chuck, in the cutter holding for being widely used in drilling machine or milling machine.Elastic circlip
By clamp-on tool after handle of a knife and locking nut compression, and by frictional force transmission moment of torsion and prevent cutter from moving axially.By rubbing
Wipe power fixed cutting tool definitely unreliable, cutter is used for a long time it is possible that locking nut loosens, and cutter, elastic card
There is elastic deformation unavoidably in spring, handle of a knife and locking nut.When therefore by elastic circlip fixed cutting tool, it sometimes appear that cutter is loose
It is dynamic, or even situation about coming off, part crudy is not only influenceed, and lathe and the safety of operating personnel can be endangered.
The content of the invention
The technical problem to be solved in the present invention is：A kind of elastic circlip that cutter can be avoided to come off is provided.
Technical scheme for the use that solves the above problems is：Set on elastic circlip with safety lock structure, elastic circlip
Safe lockhole is equipped with, safety lock axially bored line is vertical with elastic circlip axis.
It is further：Safe lockhole runs through elastic circlip.
Another technical problem to be solved by the present invention is that：A kind of tool fixing structure that cutter can be avoided to come off is provided.
Technical scheme for the use that solves the above problems is：Tool fixing structure with safety lock structure include handle of a knife,
Clamp spring hole is provided with cutter, elastic circlip and locking nut, handle of a knife, elastic circlip is located in clamp spring hole, locking nut and knife
Handle threaded connection and axial compression elastic circlip, elastic circlip clamping cutter；Also include safety locking pin；Lock pin is provided with cutter
Pass through structure；Safe lockhole is provided with elastic circlip, safety lock axially bored line is vertical with elastic circlip axis；Safety locking pin is inserted
Safe lockhole and lock pin pass through structure.
It is further：Safe lockhole runs through elastic circlip.
It is further：The laterally and tightly propped groove that lock pin has by structure for the cutter of prior art.
It is further：Including elastomer and elastomer seat, handle of a knife endoporus is provided with handle of a knife, elastomer seat is located at handle of a knife
It is connected in endoporus and with handle of a knife inner hole thread, elastomer is arranged between cutter and elastomer seat.
It is further：Elastomer is spring.
The beneficial effects of the invention are as follows：Safety locking pin inserts safe lockhole and lock pin passes through structure, the axial movement of cutter
Limited by safety locking pin, loosen and also do not fall out even if cutter.
Brief description of the drawings
Fig. 1 is the tool fixing structure assembling explosive view with safety lock structure；
Fig. 2 is the axial sectional view of the tool fixing structure with safety lock structure；
Marked in figure：Handle of a knife 1, handle of a knife endoporus 1-1, clamp spring hole 1-2, elastomer seat 2, elastic circlip 3, safe lockhole 3-
1st, locking nut 4, cutter 5, lock pin pass through structure 5-1, safety locking pin 6, elastomer 7.
Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the tool fixing structure with safety lock structure includes handle of a knife 1, cutter 5, elastic circlip 3
With locking nut 4, clamp spring hole 1-2 is provided with handle of a knife 1, elastic circlip 3 is located in clamp spring hole 1-2, locking nut 4 and handle of a knife 1
It is threadedly coupled and axial compression elastic circlip 3, the clamping cutter 5 of elastic circlip 3；Also include safety locking pin 6；, it is provided with cutter 5
Lock pin passes through structure 5-1；Safe lockhole 3-1 is provided with elastic circlip 3, safe lockhole 3-1 axis hang down with the axis of elastic circlip 3
Directly；Safety locking pin 6 inserts safe lockhole 3-1 and lock pin passes through structure 5-1.
In the tool fixing structure of the present invention, the axial movement of cutter 5 is limited by safety locking pin 6, is loosened even if cutter 5
Do not fall out.
Safe lockhole 3-1 can only extend to inside outside elastic circlip 3, but now the only one end of safety locking pin 6 is located at
In safe lockhole 3-1, the force-bearing situation of safety locking pin 6 is poor.Safe lockhole 3-1 preferably runs through elastic circlip 3, now, safety lock
The two ends of pin 6 are respectively positioned in safe lockhole 3-1, and the force-bearing situation of safety locking pin 6 is good.Safe lockhole 3-1 axis can be with elastic circlip 3
Axis intersects, can also be non-intersect.
Lock pin can aim at the hole that insertion safety locking pin 6 is designed by structure 5-1, but this can cause existing cutter 5 difficult
To be clamped using this elastic circlip 3, the versatility of influence elastic circlip 3 and tool fixing structure, and can also increase cutter 5
Manufacturing procedure.Therefore lock pin is preferably laterally and tightly propped groove by structure 5-1, and laterally and tightly propped groove is present on existing standard cutter
Groove, neither influences the versatility of elastic circlip 3 and tool fixing structure, does not also increase the manufacturing procedure of cutter 5.As shown in Fig. 2
In order to be adapted to laterally and tightly propped groove, the head of safety locking pin 6 is cylinder, and remainder should correspondingly remove portion of material.
In actual processing, the situation that cutter 5 is displaced outwardly is relatively more, thus safety locking pin 6 preferably with laterally and tightly propped groove
Inner cell wall laminating.Therefore, tool fixing structure includes being provided with handle of a knife in elastomer 7 and elastomer seat 2, handle of a knife 1
Hole 1-1, elastomer seat 2 be located at handle of a knife endoporus 1-1 in and be threadedly coupled with handle of a knife endoporus 1-1, elastomer 7 be arranged at cutter 5 and
Between elastomer seat 2.Elastomer 7 can be conventional spring.The elasticity of elastomer 7 makes it apply outside power to cutter 5, makes
Obtain in tool fixing structure assembling process, inner cell wall of the safety locking pin 6 all the time with laterally and tightly propped groove is fitted.
On existing handle of a knife 1, it is provided with handle of a knife endoporus 1-1, therefore set elastomer 7 and elastomer seat 2 not to change this more
The structure of a little handle of a knifes 1, the versatility of these handle of a knifes 1 is not influenceed.Handle of a knife 1 for being not provided with handle of a knife endoporus 1-1, can be not provided with
Elastomer 7 and elastomer seat 2, and use tool 5 of being drawn sword outside other modes；Can also specially it process for installing elastomer 7 and bullet
The hole of property housing 2.
