Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
A kind of anti-rotation structure of main spindle broach mechanism as shown in Figs 1-4, including central spindle 10, rotation preventing device 20,30 and of pull rod
Spring 40；The rotation preventing device 20 is fixedly connected with the central spindle 10, and is provided with the first location structure 21；The pull rod 30 is actively located in
In the central spindle 10, and it is provided with the second location structure 31；First location structure 21 and second location structure 31 inserting cooperation,
And first location structure 21 also cooperates with 31 activity of the second location structure, so that pull rod 30 can be moved up and down with respect to central spindle 10；
The pull rod 30 is also provided with third location structure 32；The spring 40 is set in outside the pull rod 30, and is located in the central spindle 10；The bullet
Spring 40 is provided with the 4th location structure 41, and the 4th location structure 41 cooperates with the third location structure 32 inserting.
On the basis of above structure, during main shaft unloads knife or broaching tool, pull rod 30 moves down compressed spring 40
Perhaps spring 40 rotates or because compressing stress because natural resiliency stress resets when pull rod 30 moves up release spring 40
When rotating, the rotary force of the spring 40 of the above process is transferred to third location structure 32 through the 4th location structure 41, later
It is transferred on pull rod 30, rotary force suffered by pull rod 30 is transferred to the first location structure 21 through the second location structure 31 and passes at this time
It is handed on rotation preventing device 20, rotary force is transferred to central spindle 10 again by rotation preventing device 20, and makes spring 40, pull rod 30 and central spindle 10 3
Synchronized rotation occurs for person, at this point, spring 40, pull rod 30,10 three of central spindle are opposing stationary, i.e. spring 40 and pull rod 30 is without generation
Relative to the rotation of central spindle 10, and the aequum for avoiding main shaft changes, it is ensured that the machining accuracy of main shaft.

Structure 31 is the convex block being fixed on pull rod 30；The first above-mentioned location structure 21 can also be first be fixed on the rotation preventing device 20
Locating piece, correspondingly, second location structure 31 are the first locating slot being provided on the pull rod 30, in this way, pull rod 30 by
When to rotary force, the first locating slot is rotated with pull rod 30, at this point, the cell wall of the first locating slot pushes the first locating piece, and is realized
Power is transferred to the first locating piece；It is above-mentioned that structure is simple and easy to implement, and groove or the first locating slot can be used one at
The manufacture of type technique, can also be used later period drilling processing and is formed；Integral forming process can be used in above-mentioned convex block, the first locating piece
Manufacture is also fixed with modes such as the use later period are spirally connected, weld.
Above-mentioned third location structure 32 can be the convex block being fixed on pull rod 30, and correspondingly, the 4th location structure 41 is
The groove being provided on spring 40；Furthermore above-mentioned third location structure 32 can also be the second positioning being provided on pull rod 30
Slot, correspondingly, the 4th location structure 41 are the second locating piece being fixed on spring 40.
Preferably, spring 40 is flocking double wrap spring 40.Need to illustrate herein when, above-mentioned flocking double wrap spring 40 is
Refer to that appearance is implanted into villous, and the spring 40 with identical two spiral coil of the hand of spiral；Above-mentioned flocking double wrap spring 40 has
There is very strong anti-friction ability, and after being arranged flocking double wrap spring 40 in central spindle 10,40 appearance of flocking double wrap spring
Villus open and prop up the inner wall of central spindle 10, guarantee that it is larger with 10 inner wall contact area of central spindle, and then can prevent in movement
During main shaft, the possibility mobile relative to central spindle 10 of spring 40 serves and positions oneself.
Specifically, rotation preventing device 20 is fixedly connected by coding disk 50 with central spindle 10.Above-mentioned coding disk 50 can pass through screw thread
The mode of connection is connect with central spindle 10, is fixed in central spindle 10 using pin later, in this way, easy to disassemble.
Further, the anti-rotation structure of this main spindle broach mechanism further includes piston 60；Piston 60 is fixedly connected with pull rod 30.
It can avoid piston 60 to rotate relative to central spindle 10, and further decrease the possibility for causing abrasion to piston 60.
Specifically, rotation preventing device 20 is hollow torsional stop, and torsional stop is set in outside pull rod 30, and torsional stop inner ring is opposite
Two sides are respectively arranged with the first location structure 21；Pull rod 30 is provided with two be arranged in a one-to-one correspondence with two first location structures 21
Second location structure 31.In this way, inserting is corresponded by two the first location structures 21 and two the second location structures 31, it can
The harmony of rotary force transmittance process is improved, and is avoided during power transmission rotary force, 30 run-off the straight of pull rod.
The above embodiment is only the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto,
The variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed range.
