Description
Technical field
The present invention relates to a kind of vertical broaching machines, more particularly, to a kind of vertical broaching machine main folder cutter head.
Background technique
Currently, the main folder cutter head used on vertical broaching machine, most of main folder cutter head is semicircle as shown in Fig. 1,
In the case that broaching tool leaves collet, iron filings enter in the gap between collet body and claw a, even if using with air blowing or punching
The device of water is also difficult that iron filings are discharged, and when the upward claw of slide unit, causing claw to be obstructed can't clip broaching tool, and broaching machine circulation is dynamic
It is unable to run.Cross-section structure mushroom-shaped main folder cutter head as shown in Fig. 2, this main folder cutter head upper clipping claw a ' and collet body it
Will not block between although and stay iron filings, claw a ' when blocking broaching tool be easy occur because bearing cutting force it is severely deformed, especially
It is the broaching machine of large-tonnage.Above-mentioned vertical broaching machine main folder cutter head has the disadvantage in that stress is bad, accumulates iron filings, transports in lathe
Knife is pressed from both sides in row to have some setbacks, claw is often scratched by iron filings, it needs replacing, so that efficiency is relatively low when broaching machine process component product,
It is at high cost to replace accessory.
202151780 U of CN discloses a kind of chuck body structure, axial for accommodating broaching tool in collet body including being located at
Through-hole, have on the outer peripheral surface of the collet body and radially prolong secondary pin hole along the collet body, inserted with fixed in the pin hole
Position pin, the positioning pin crosses entire through-hole and broaching tool is placed on the positioning pin.Positioning pin master in the chuck body structure
It is used to clamp broaching tool knife handle, prevents broaching tool from gliding, convenient for the downslide discharge of the iron filings generated in broaching tool operational process, cannot solve
The problem of certainly pressing from both sides the accumulation iron filings in gap between cutter hub and claw.
Summary of the invention
The technical problem to be solved by the present invention is overcoming the deficiencies of the prior art and provide, a kind of structure is simple, service life
The vertical broaching machine main folder cutter head of long, uniform force and not long-pending iron filings, and the vertical broaching machine containing the main folder cutter head.
The technical solution adopted by the present invention to solve the technical problems is: a kind of vertical broaching machine main folder cutter head, including top cap,
Set, sliding sleeve, claw, folder cutter hub and shift fork；The top cap is fixed on the upper surface of folder cutter hub；One end of the claw and sliding sleeve connect
It connects；Described sliding sleeve one end is connect by set with top cap, and the other end is connect with shift fork, and is slided up and down under the drive of shift fork；
Several claws are equipped on the inside of the sliding sleeve, the claw is cylindrical pin shape structure；
Further, the quantity of the claw is 2 ~ 6, and circumferentially formula is distributed on the outside of folder cutter hub, true according to knife handle size
Determine the quantity of claw, preferably 4 claws.
Further, the claw includes integrally formed pin and pin cap, and the front end of the pin is equipped with to pin front end
The inclined cambered surface of the central point in face；The two sides of the pin cap offer the spring fixed hole connecting with reset spring.
Further, the cambered surface of the pin is processed on the same mill mill of grinding machine, it is ensured that multiple cambered surfaces and broaching tool are simultaneously
Fitting, keeps its loading angle identical and uniform force.
Further, the tilt angle of cambered surface is consistent with broaching tool, it is preferable that the tilt angle of cambered surface is 45 °, and cambered surface bottom is arrived
The distance of the central point of pin front end face is more than or equal to the vertical height of cambered surface.
Further, interior in the middle part of the folder cutter hub to be equipped with cushion.
Further, the folder cutter hub is equipped with the first round nut and the second round nut far from the end of top cap.
Further, lateral wall is equipped with key in the middle part of the folder cutter hub.
A kind of vertical broaching machine, including above-mentioned main folder cutter head.
Further, it is equipped with blowning installation above main folder cutter head, broaching tool knife handle is made to be not easy to be worn by iron filings with top cap.
A kind of operation principle and using method of vertical broaching machine main folder cutter head of the present invention is: folder knife oil cylinder drives shift fork, dials
Fork drives sliding sleeve to slide up and down, so that claw opens or gathers in sliding sleeve, clamping broaching tool can be completed or unclamp the dynamic of broaching tool
Make.
Compared with existing semicircle claw, since the claw on the vertical broaching machine main folder cutter head is in cylinder latch structure,
Outer surface is arc surface, is inclined cambered surface with the places of broach holder cutter hub location contacts, iron filings be difficult to be attached to arc surface or
In inclined cambered surface, and then solve the problems, such as to accumulate iron filings between claw and folder cutter hub, and columnar pin is to drawing
The phenomenon that snap action of knife is good, deforms there is no mushroom-shaped claw when bearing cutting force.
A kind of vertical broaching machine main folder cutter head of the present invention the utility model has the advantages that structure by changing claw, using cylindrical pin shape
Structure, reduces the accumulation of main folder cutter head portion iron filings in vertical broaching machine use process, and then avoids claw to broaching tool clamping shakiness
Phenomenon.
