Description
Technical field
The utility model relates to machine tool field, particularly relates to a kind of elastic circlip of safety lock structure and utilize the tool fixing structure of this jump ring fixed cutting tool of having.
Background technology
Elastic circlip, also known as elastic collet chuck or collet chuck, is widely used in the cutter holding of drilling machine or milling machine.Elastic circlip by clamp-on tool after handle of a knife and locking nut compression, and relies on frictional force transmitting torque and prevents cutter from moving axially.Definitely unreliable by frictional force fixed cutting tool, cutter Long-Time Service may occur that locking nut loosens, and cutter, elastic circlip, handle of a knife and locking nut occur elastic deformation unavoidably.Therefore, time by elastic circlip fixed cutting tool, occur that cutter loosens sometimes, situation about even coming off, not only affect part crudy, and the safety of lathe and operating personnel can be endangered.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of elastic circlip that cutter can be avoided to come off.
In order to solve the problem, the technical scheme adopted is: the elastic circlip with safety lock structure, elastic circlip is provided with safe lockhole, safety lock axially bored line and elastic circlip axes normal.
Further: safe lockhole runs through elastic circlip.
Another technical problem to be solved in the utility model is: provide a kind of tool fixing structure that cutter can be avoided to come off.
In order to solve the problem, the technical scheme adopted is: the tool fixing structure with safety lock structure comprises handle of a knife, cutter, elastic circlip and locking nut, clamp spring hole is provided with in handle of a knife, elastic circlip is positioned at clamp spring hole, locking nut is threaded with handle of a knife and axial compression elastic circlip, elastic circlip clamping cutter; Also comprise safety locking pin; Cutter is provided with lock pin and passes through structure; Elastic circlip is provided with safe lockhole, safety lock axially bored line and elastic circlip axes normal; Safety locking pin inserts safe lockhole and lock pin passes through structure.
Further: safe lockhole runs through elastic circlip.
Further: the laterally and tightly propped groove that the cutter that lock pin is prior art by structure has.
Further: comprise elastomer and elastomer seat, be provided with handle of a knife endoporus in handle of a knife, elastomer seat is positioned at handle of a knife endoporus and is connected with handle of a knife inner hole thread, and elastomer is arranged between cutter and elastomer seat.
Further: elastomer is spring.
The beneficial effects of the utility model are: safety locking pin inserts safe lockhole and lock pin by structure, and the axially-movable of cutter is limited by safety locking pin, also can not drop even if cutter loosens.
Accompanying drawing explanation
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;
Be labeled as 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 3-1, locking nut 4, cutter 5, lock pin are by structure 5-1, safety locking pin 6, elastomer 7.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As depicted in figs. 1 and 2, the tool fixing structure with safety lock structure comprises handle of a knife 1, cutter 5, elastic circlip 3 and locking nut 4, clamp spring hole 1-2 is provided with in handle of a knife 1, elastic circlip 3 is positioned at clamp spring hole 1-2, locking nut 4 is threaded with handle of a knife 1 and axial compression elastic circlip 3, and elastic circlip 3 clamps cutter 5; Also comprise safety locking pin 6; , cutter 5 is provided with lock pin by structure 5-1; Elastic circlip 3 is provided with safe lockhole 3-1, safe lockhole 3-1 axis and elastic circlip 3 axes normal; Safety locking pin 6 inserts safe lockhole 3-1 and lock pin by structure 5-1.
In tool fixing structure of the present utility model, the axially-movable of cutter 5 is limited by safety locking pin 6, even if cutter 5 loosens also can not drop.
Safe lockhole 3-1 only can extend to inside by elastic circlip 3 outside, but now safety locking pin 6 is only positioned at safe lockhole 3-1 in one end, and safety locking pin 6 force-bearing situation is poor.Safe lockhole 3-1 preferably runs through elastic circlip 3, and now, safety locking pin 6 two ends are all positioned at safe lockhole 3-1, and safety locking pin 6 force-bearing situation is good.Safe lockhole 3-1 axis can with elastic circlip 3 axes intersect, also can be non-intersect.
Lock pin can be aim at the hole of inserting safety locking pin 6 and designing by structure 5-1, but this can cause existing cutter 5 to be difficult to adopt this elastic circlip 3 to clamp, the versatility of influence elastane jump ring 3 and tool fixing structure, and the manufacturing procedure that can increase cutter 5.Therefore lock pin is preferably laterally and tightly propped groove by structure 5-1, and laterally and tightly propped groove is the groove that existing standard cutter exists, neither the versatility of influence elastane jump ring 3 and tool fixing structure, does not also increase the manufacturing procedure of cutter 5.As shown in Figure 2, in order to adaptive with laterally and tightly propped groove, safety locking pin 6 head is cylindrical, and remainder correspondingly should remove portion of material.
In actual processing, the situation of the outside movement of cutter 5 is relatively many, and therefore safety locking pin 6 is preferably fitted with the inner cell wall of laterally and tightly propped groove.For this reason, tool fixing structure comprises elastomer 7 and elastomer seat 2, is provided with handle of a knife endoporus 1-1 in handle of a knife 1, and elastomer seat 2 is positioned at handle of a knife endoporus 1-1 and is threaded with handle of a knife endoporus 1-1, and elastomer 7 is arranged between cutter 5 and elastomer seat 2.Elastomer 7 can for conventional spring.The elasticity of elastomer 7 makes it apply outside power to cutter 5, makes in tool fixing structure assembling process, and safety locking pin 6 is fitted with the inner cell wall of laterally and tightly propped groove all the time.
On existing handle of a knife 1, be provided with handle of a knife endoporus 1-1 more, therefore the structure that elastomer 7 and elastomer seat 2 can not change these handle of a knifes 1 be set, do not affect the versatility of these handle of a knifes 1.For the handle of a knife 1 not arranging handle of a knife endoporus 1-1, elastomer 7 and elastomer seat 2 can not be set, and adopt tool 5 of drawing sword outside other modes; Also the hole for installing elastomer 7 and elastomer seat 2 can be processed specially.
