Abstract
The utility model relates to the technical field of hardware cutting tools, and particularly relates to a circular cutter for a packaging machine. The circular cutter for the packaging machine comprises a circular cutter head and an edge part arranged on the outer periphery of the cutter head, wherein an assembling hole and a plurality of fixing holes are formed in the cutter head, an antiskid check ring is arranged on one side of the cutter head, and the check ring is arranged along the edge of the assembling hole and concentrically arranged together with the assembling hole; a plurality of limiting gaps are formed in the check ring. The circular cutter is reasonable in structure, and can be fixed on a main shaft through matching and locking the check ring and the fixing holes; the limiting gaps in the check ring are meshed with a locating block on the main shaft in assembling, so that the assembling efficiency and the connection strength can be enhanced, the slippage situation of the cutter can be effectively avoided.
Description
Technical field
The utility model relates to hardware and cutting-tools technical field, particularly a kind of packing machine round cutting-off tool.
Background technology
The hardware and cutting-tools using in machining comprises lathe tool, milling cutter, planing tool, fluted drill etc., and milling cutter is wherein the manufacturing procedures such as cutting for piece surface, groove milling, quit a post and thus leave it vacant.In various processing, due to the clamping gap of fixture and the impact of cutting force, often there will be skidding to cause the damage of milling cutter.For avoiding this problem, conventionally operative employee understands excessive screwing chuck etc. to increase the clamping dynamics to milling cutter, until that sensation is twisted is motionless.But excessive clamping can cause the gap of chuck to increase, and to handle of a knife distortion and then reduce milling cutter service life.The situation of skidding of the disc type milling cutter work in-process wherein using in packing machine is especially serious, the stator of milling cutter is sheathed on the main shaft of lathe, then after being screwed by hold-down nut with its rotation, when encountering excessive cutting, be easy to the situation of skidding, and the location that is also unfavorable for cutter, is therefore necessary this to be improved avoid the problems referred to above.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of packing machine round cutting-off tool simple in structure, easy to use is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of packing machine round cutting-off tool described in the utility model, comprise circular cutterhead and be located at the blade in cutterhead periphery, described cutterhead is provided with pilot hole and some fixing holes, and cutterhead one side is provided with anti-skidding back-up ring, and described back-up ring is along the setting of pilot hole edge concentric setting; Described back-up ring is provided with some spacing breach.
Further, the circumference of described some fixing holes centered by pilot hole arranges for first-class minute, and some fixing holes are no less than three.
Further, the setting corresponding to fixing hole of described spacing breach, and spacing breach is located on the angle center line between adjacent fixing hole and cutterhead center.
Further, the V-shaped opening setting of described spacing breach and V-arrangement opening deviate from cutterhead, and the V-arrangement opening of spacing breach inwardly narrows along back-up ring outer rim.
The utility model beneficial effect is: the utility model is rational in infrastructure, by back-up ring and fixing hole, lock cutting knife is fixed on main shaft, the locating piece interlock of spacing breach on back-up ring when assembling and on main shaft, improves efficiency of assembling and bonding strength, effectively avoids the situation of skidding of cutter.
Accompanying drawing explanation
Fig. 1 is side structure schematic diagram of the present utility model;
Fig. 2 is front of the present utility model sectional structure schematic diagram.
In figure:
1, cutterhead; 11, blade; 12, back-up ring; 13, spacing breach;
14, fixing hole; 15, pilot hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in Fig. 2, a kind of packing machine round cutting-off tool described in the utility model, comprise circular cutterhead 1 and be located at the blade 11 in cutterhead 1 periphery, blade 11 is the non-standard molding edge of a knife for groove milling cutting, described cutterhead 1 is provided with pilot hole 15 and some fixing holes 14, pilot hole 15 and fixing hole 14 dock with main shaft on lathe when mounted, fixing hole 14 is fixed with nut after being socketed on main shaft connecting bolt, and fixing hole 14 is ring groove shape and then makes cutterhead 1 on main shaft, have certain rotation surplus.The circumference of some fixing holes 14 centered by pilot hole 15 arranges for first-class minute, and some fixing holes 14 are no less than three, and fixing hole 14 quantity improve the intensity that is linked and packed more at most still can reduce efficiency of assembling, so the preferred some fixing holes 14 of this programme are three.
Cutterhead 1 one sides are provided with anti-skidding back-up ring 12, and described back-up ring 12 is along pilot hole 15 edge settings concentric setting; Described back-up ring 12 is provided with some spacing breach 13; The setting corresponding to fixing hole 14 of described spacing breach 13, and spacing breach 13 is located on the angle center line between adjacent fixing hole 14 and cutterhead 1 center; After projection interlock on spacing breach 13 and main shaft, cutterhead 1 screws nut by fixing hole 14 and fixes, and improves the bonding strength between cutterhead 1 and main shaft.The V-shaped opening setting of described spacing breach 13 and V-arrangement opening deviate from cutterhead 1, and the V-arrangement opening of spacing breach 13 inwardly narrows along back-up ring 12 outer rims; The V-arrangement opening of spacing breach 13 is finely tuned the gap coordinating when the projection interlock with on main shaft, improves efficiency of assembling and bonding strength, effectively avoids the situation of skidding of cutter.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
