Description
Technical field
This utility model relates to machine tool field, particularly relates to a kind of tool fixing structure and is applicable to this
The cutter of tool fixing structure and handle of a knife.
Background technology
Thermal insert knife handle is widely used in cutter holding, is provided with cutter holes in handle of a knife.During clamping cutter, add
Hot handle of a knife makes cutter holes expand, and then cutter inserts cutter holes, and after handle of a knife cooling, cutter holes contraction will cutter
Tool clamping.Generally thermal insert knife handle can stably clamp cutter, it is to avoid cutter moves axially.But some is special
In the case of, it may appear that the situation that cutter moves axially, such as, after cutter is processed for a long time, it may appear that cutter
The situation of the most a small amount of movement, and situation about being displaced outwardly based on cutter.Even if cutter axially moves on a small quantity
Also can affect the machining accuracy of cutter, even cause part rejection.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of it can be avoided that the cutter that cutter moves is fixed
Structure.
The technical scheme is that tool fixing structure includes handle of a knife and cutter, handle of a knife for solving the problems referred to above
Inside being provided with the cutter holes extended internally by handle of a knife end, cutter inserts cutter holes, handle of a knife clamping cutter；Also
Including safety locking pin；The lockpin hole extended internally by handle of a knife sidepiece it is provided with in handle of a knife；Lock it is provided with on cutter
Pin is by groove and withdrawing concave station, and withdrawing concave station is extended to lock pin by cutter end face and passes through groove；Safety locking pin loads
Lockpin hole also inserts lock pin by groove, and safety locking pin limits cutter and moves axially；Handle of a knife releases the folder to cutter
Hold and cutter rotate to withdrawing concave station and safety locking pin just pair time, cutter movement outside handle of a knife is not by safety
Lock pin limits.
Further: safety locking pin passes through groove through lock pin.
Further: safety locking pin, lock pin are all vertical with the axis of cutter by groove.
Further: tool fixing structure include being arranged at the bottom of cutter holes hole with cutter before elastomer.
Further: elastomer is spring.
To be solved in the utility model another technical problem is that: provides one to be applicable to above-mentioned tool fixing structure
Cutter.
The technical scheme is that being provided with lock pin on cutter passes through groove and withdrawing concave station for solving the problems referred to above,
Withdrawing concave station is extended to lock pin by cutter end face and passes through groove.
Further: lock pin is vertical with the axis of cutter by groove.
To be solved in the utility model another technical problem is that: provides one to be applicable to above-mentioned tool fixing structure
Handle of a knife.
Extend internally by handle of a knife end for solving to be provided with in the problems referred to above the technical scheme is that handle of a knife
Cutter holes, is provided with the lockpin hole extended internally by handle of a knife sidepiece in handle of a knife, lockpin hole passes through mutually with cutter holes.
Further: lockpin hole is vertical with cutter holes.
The beneficial effects of the utility model are: safety locking pin limits cutter and moves axially, it is possible to avoid cutter shaft
To moving influence machining accuracy.Handle of a knife releases clamping and rotary cutter to cutter and makes withdrawing concave station and safety
Lock pin is the most right, and safety locking pin i.e. releases the restriction moving axially cutter so that cutter can be dismantled and install.
When therefore using this tool fixing structure, it is not necessary to operation safety locking pin, it is only necessary to rotary cutter can dismount cutter,
The dismounting of cutter is the easiest.
Accompanying drawing explanation
Fig. 1 is the assembling explosive view of tool fixing structure；
Fig. 2 is the axial sectional view of tool fixing structure；
Fig. 3 is the A-A sectional view of Fig. 2.
Figure is labeled as: handle of a knife 1, lockpin hole 2, safety locking pin 3, elastomer seat 4, elastomer 5, cutter
6, cutter holes 7, lock pin are by groove 8, withdrawing concave station 9.
Detailed description of the invention
With detailed description of the invention, this utility model is further illustrated below in conjunction with the accompanying drawings.
Tool fixing structure includes handle of a knife 1 and cutter 6, is provided with and is extended internally by handle of a knife 1 end in handle of a knife 1
Cutter holes 7, cutter 6 inserts cutter holes 7, and handle of a knife 1 clamps cutter 6；Also include safety locking pin 3；Cutter
The lockpin hole 2 extended internally by handle of a knife 1 sidepiece it is provided with in handle 1；Lock pin it is provided with by groove 8 on cutter 6
With withdrawing concave station 9, withdrawing concave station 9 is extended to lock pin by groove 8 by cutter 6 end face；Safety locking pin 3 loads
Lockpin hole 2 also inserts lock pin by groove 8, and safety locking pin 3 limits cutter 6 and moves axially；It is right that handle of a knife 1 releases
The clamping of cutter 6 and cutter 6 rotate to withdrawing concave station 9 and safety locking pin 3 just pair time, cutter 6 is to cutter
Movement outside handle 1 is not limited by safety locking pin 3.
During assembling, the sidewall that lock pin should be made to pass through groove 8 is fitted with safety locking pin 3, of cutter 6
Moving axially of direction is stopped by safety locking pin 3, and therefore safety locking pin 3 can limit 6 one directions of cutter
Move axially.More typically, it is inner to be the most generally that lock pin passes through groove 8 for the situation that cutter 6 is displaced outwardly
Sidewall fit with safety locking pin 3.Lock pin is custom-designed groove by groove 8, can design and ensure to add
Two sidewalls that work accuracy makes lock pin pass through groove 8 are all fitted with safety locking pin 3, such safety locking pin 3 energy
Enough limit moving axially of cutter 6 both direction.
Safety locking pin 3 can be to insert lockpin hole 2.Safety locking pin 3 need not rotate, therefore safety locking pin 3
Should be interference fit with lockpin hole 2.Safety locking pin 3 can also be threadeded with lockpin hole 8
Lock pin can be straight trough as shown in Figure 1 to Figure 3 by groove 8, it is also possible to is cannelure or arcuate groove.
Withdrawing concave station 9 can be as it is shown on figure 3, become 90 degree of angles with lock pin by groove 8, it is also possible to is other angle.
Cutter 6 rotary course should not interfered with safety locking pin 3, can be as it is shown on figure 3, make lock pin pass through groove 8
With withdrawing concave station 9 arc transition.
Safety locking pin 3 can only insert but be not passed through lock pin and pass through groove 8, but this situation safety locking pin 3 is outstanding
Arm beam, intensity is bad, and therefore safety locking pin 3 preferably passes through lock pin by groove 8, and safety locking pin 3 is best
Vertical with cutter 6.Correspondingly, lock pin is vertical with the axis of cutter 6 by groove 8, lockpin hole 2 and cutter
Hole 7 is vertical.
As it was previously stated, the situation that cutter 6 is displaced outwardly is more typically, it is inner to be generally that lock pin passes through groove 8
Sidewall is fitted with safety locking pin 3.The tool fixing structure for this with safety lock structure includes being arranged at cutter
Elastomer 5 at the bottom of hole, hole 7 and before cutter 6.Elastomer 5 can be conventional spring.The bullet of elastomer 5
Property make it apply outside power to cutter 6 so that lock pin is pasted with safety locking pin 3 by the inner sidewall of groove 8
Close.As in figure 2 it is shown, elastomer seat 4 can be connected at the bottom of cutter holes 7 hole, elastomer seat 4 may be used for
Support elastomer 5 it can also be used to prevent elastomer 5 from tilting.Cooling water hole can be set in elastomer seat 4,
Cooling water enters cutter 6 to avoid elastomer seat 4 to stop.
This utility model is primarily adapted for use in thermal insert knife handle it can also be used to other handle of a knife.
