The device of water also is difficult to discharge iron filings, when slide unit upwardly claw, leads to claw to be obstructed and can't clip broaching tool, and broaching machine circulation is dynamic
Work cannot run.Cross-section structure mushroom-shaped main folder cutter head as shown in Figure 2, this main folder cutter head upper clipping claw a ' and collet body it
Although between will not block and stay iron filings, easily there is gross distortion because bearing cutting force when blocking broaching tool in claw a ', especially
It is large-tonnage broaching machine.Above-mentioned vertical broaching machine main folder cutter head has the disadvantage in that stress is bad, accumulates iron filings, in lathe fortune
In row, folder knife has some setbacks, claw often by iron filings scratch, need to change so that during broaching machine process component product efficiency low,
Change accessory high cost.
Cn 202151780 u discloses a kind of chuck body structure, including axial direction in collet body for housing broaching tool
Through hole, the outer peripheral face of described collet body has and prolongs secondary pin-and-hole along described collet body radial direction, it is fixed that described pin-and-hole has been inserted into
Position pin, described alignment pin crosses whole through hole and broaching tool is placed on described alignment pin.Alignment pin master in this chuck body structure
It is used for clamping broaching tool handle of a knife, prevents broaching tool from gliding, the downslide being easy to the iron filings of generation in broaching tool running is discharged it is impossible to solve
Certainly press from both sides the problem of the accumulation iron filings in space between cutter hub and claw.
Utility model content
The technical problems to be solved in the utility model is: overcomes the deficiencies in the prior art, provides that a kind of structure is simple, uses
The vertical broaching machine main folder cutter head of life-span length, uniform force and long-pending iron filings, and the vertical broaching machine containing this main folder cutter head.
This utility model solves its technical problem and be the technical scheme is that a kind of vertical broaching machine main folder cutter head, including
Top cap, set, sliding sleeve, claw, folder cutter hub and shift fork；Described top cap is fixed on above folder cutter hub；One end of described claw and cunning
Set connects；Described sliding sleeve one end pass through set be connected with top cap, its other end is connected with shift fork, and under the drive of shift fork on downslide
Dynamic；It is provided with several claws, described claw is cylindrical pin shape structure inside described sliding sleeve；
Further, the quantity of described claw is 2 ~ 6, and circumferentially formula is distributed in outside folder cutter hub, true according to handle of a knife size
Determine the quantity of claw, preferably 4 claws.
Further, described claw includes integrally formed pin and pin cap, and the front end of described pin is provided with to pin front end
The cambered surface that the central point in face tilts；The both sides of described pin cap offer the spring fixed hole being connected with back-moving spring.
Further, the cambered surface of described pin on the same mill mill of grinding machine processing it is ensured that multiple cambered surface with broaching tool simultaneously
Laminating is so as to loading angle is identical and uniform force.
Further, the angle of inclination of cambered surface consistent with broaching tool it is preferable that cambered surface angle of inclination be 45 °, 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 it is provided with cushion pad in the middle part of described folder cutter hub.
Further, described folder cutter hub is provided with the first round nut and the second round nut away from the end of top cap.
Further, in the middle part of described folder cutter hub, lateral wall is provided with key.
A kind of vertical broaching machine, including above-mentioned main folder cutter head.
Further, it is provided with blowning installation above main folder cutter head, make broaching tool handle of a knife and top cap be difficult to be worn and torn by iron filings.
A kind of operation principle of this utility model vertical broaching machine main folder cutter head and using method are: folder knife oil cylinder drives to be dialled
Fork, shift fork drives sliding sleeve to slide up and down so that claw opens in sliding sleeve or gathers, you can completes to clamp broaching tool or unclamps broaching tool
Action.
Compared with existing semicircle claw, because the claw on this vertical broaching machine main folder cutter head is in cylinder latch structure, its
Outer surface is arc surface, and the place with broach holder cutter hub location contacts is the cambered surface tilting, iron filings be difficult to be attached to arc surface or
In the cambered surface tilting, and then efficiently solve the difficult problem accumulating iron filings between claw and folder cutter hub, and the pin of column is to drawing
The snap action of knife is good, there is not the phenomenon that mushroom-shaped claw deforms when bearing cutting force.
The beneficial effect of this utility model a kind of vertical broaching machine main folder cutter head: by changing the structure of claw, using cylinder
Pin-shaped structure, reduces the accumulation of main folder cutter head portion iron filings during vertical broaching machine uses, and then avoids claw that broaching tool is clamped not
Steady phenomenon.
