Abstract
The invention discloses a fly cutter mounting structure of a drum chipper. The fly cutter mounting structure comprises a fly cutter base arranged on a cutter roll and used for mounting a fly cutter and a nut provided with an internal thread and an external thread, wherein the fly cutter base is provided with a threaded hole; the nut is arranged in the threaded hole by virtue of the external thread; the boundary between the nut and the fly cutter base is provided with a fastening screw capable of preventing the nut from rotating; the fly cutter is arranged on the fly cutter base, then is matched with the internal thread of the nut by virtue of a fastening bolt and is used for clamping and fixing the fly cutter. After such a structure is adopted, the nut is provided with the external thread in a detachable mode instead of a traditional welding mode; the fly cutter is clamped and fixed by virtue of cooperation of the bolt and the nut; during replacement, only the nut is required to be screwed out, so that the replacement cost is lowered, and continuous production is ensured.
Description
Technical field
The present invention relates to a kind of component mounting structure of drum chipper, specifically a kind of drum chipper fly cutter mounting structure, belongs to wood processing equipment technical field.
Background technology
Drum chipper is a kind of special equipment of production technology wood chip.Be widely used in the industrial production such as medium density fibre board (MDF), ordinary particle board and papermaking, as one of wood chip material papering section main frame, also can be used as the unit producing wood chip and use; Drum chipper cuts raw material and is mainly undersized log, harvesting of wood residue (branch, branch etc.), wood machining residues (lath, slab, garden reel, waste single boards etc.) etc., its feature has compact conformation reasonable, easy and simple to handle, productivity ratio is high, adaptability to raw material is wide, and cutting chip quality is high, safe and reliable, easy to maintenance, be drum chipper more advanced both at home and abroad at present.
The cutting knife roller that drum chipper high speed rotates is furnished with 2-4 fly cutter, and fly cutter is consumable accessory, each order of classes or grades at school must remove the fly cutter of wearing and tearing, changes the fly cutter after new sharpening; Therefore the fly cutter bolt of fly cutter and screwed hole thereof is fixed through being dismounted for multiple times, often there is the phenomenon of screw thread plucking or sliding tooth, it is very convenient that fly cutter bolt renews, but be difficult to process after the screwed hole plucking of fixing fly cutter bolt or sliding tooth, can adopt in early days and strengthen the method for the diameter of thread and process, but again just cannot process after plucking or sliding tooth, the rotor that must again renew, one to carry out replacement cost high, and two is the continuous seepage affecting factory.
Summary of the invention
The present invention relates to one and can reduce replacement cost, ensure quantity-produced drum chipper fly cutter mounting structure.
In order to solve the problems of the technologies described above, drum chipper fly cutter mounting structure of the present invention, comprise the fly cutter seat for settling fly cutter be arranged on cutting knife roller, fly cutter seat is provided with a screwed hole, also comprise one and there is internal thread and externally threaded nut simultaneously, nut is arranged in screwed hole by external screw thread, the border of nut and fly cutter seat is provided with the trip bolt that can prevent nut rotation, fly cutter to be placed in after on fly cutter seat by the screw-internal thread fit of a fastening bolt and nut and to be gripped by fly cutter.
One piece of cushion block is provided with between described fly cutter and fly cutter seat.
Described fastening bolt is dormant bolt.
Described fly cutter is provided with one piece of briquetting, fly cutter is fixed by briquetting by fastening bolt.
The cross sectional shape of described fly cutter seat is L shape, the vertical edge of fly cutter seat is provided with a groove, the rear end face of briquetting is provided with one with the projection of groove fit, during installation, briquetting is fixed by fly cutter seat upper groove and the projection on the rear end face of briquetting are spacing.
After adopting above-mentioned structure, while arranging, there is internal thread and externally threaded nut, nut is arranged in screwed hole by external screw thread, the border of nut and fly cutter seat is provided with trip bolt, nut to be coordinated with screwed hole by external screw thread install, nut rotation is prevented by trip bolt after installing, fly cutter to be placed in after on fly cutter seat by the screw-internal thread fit of a fastening bolt and nut and to be gripped by fly cutter, its nut be not adopt traditional welding manner but by detachable form with externally threaded nut, fly cutter is gripped again by the cooperation of bolts and nuts, during replacing, only nut need be screwed out, thus reduce replacement cost, ensure that continuous seepage.
Accompanying drawing explanation
Fig. 1 is the structural representation of drum chipper fly cutter mounting structure of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, drum chipper fly cutter mounting structure of the present invention is described in further detail.
As shown in the figure, of the present inventionly comprise the fly cutter seat 2 for settling fly cutter 1 be arranged on cutting knife roller, fly cutter seat 2 is provided with a screwed hole, also comprise one and there is internal thread and externally threaded nut 3 simultaneously, nut 3 is arranged in screwed hole by external screw thread, nut 3 and the border of fly cutter seat 2 are provided with the trip bolt 4 that can prevent nut 3 from rotating, fly cutter 1 to be placed in after on fly cutter seat 2 by the screw-internal thread fit of a fastening bolt 5 and nut 3 and to be gripped by fly cutter 1, one piece of cushion block 6 can also be provided with between fly cutter 1 and fly cutter seat 2, wherein fastening bolt 5 is preferably dormant bolt, fly cutter 1 is provided with one piece of briquetting 7, fly cutter 1 is fixed by briquetting by fastening bolt 5.
Further, the cross sectional shape of fly cutter seat 2 is L shape, the vertical edge of fly cutter seat 2 is provided with a groove, the rear end face of briquetting 7 is provided with one with the projection of groove fit, during installation, briquetting 7 is fixed by fly cutter seat 2 upper groove and the projection on the rear end face of briquetting 7 are spacing.
Dismountable with externally threaded nut by adopting on the fly cutter seat of rotor in the present invention, fix with holding screw during fine finishining assembling, like this when fastening bolt and internal thread are fastening, when there is screw thread plucking or cunning tooth, change internal and external threads to overlap, not only save time but also cost-saving.
