Abstract
The utility model relates to a rough boring, including blade holder body and cutter body, blade, the excircle of blade holder body adopts the double arc structure, and the blade holder body be split type structure, and a plurality of components of a whole that can function independently blade holder subsides merga pass bolt fastening is equipped with the circular arc mesa below the blade on the cutter body, circular arc mesa and blade holder body constitute a working chamber, and the chip pocket is connected to the side of this circular arc mesa, and the root of this chip pocket is banding arc recess, the terminal radius angle of this root, the utility model discloses but the quick replacement part, and increaseed and held the bits space, and can accomplish quick chip removal, guarantee going on smoothly of processing.
Description
Technical field
The utility model relates to cutting element, specifically a kind of rough boring cutter.
Background technology
Rough boring cutter belongs to the one of cutting element, and rough boring cutter is mainly used in needing the workpiece of processing to carry out preliminary cutting.Traditional heavy boring, has plenty of tool rest and the mutual Luo of cutter hub connects, also have tool rest and cutter hub integrated, and the tool rest of majority is overall, tool rest is fixed polylith blade, occurring chipping man-hour because of carelessness when adding, whole tool rest is then needed to change, one, replacement cost is high, and two, overall structure is more loaded down with trivial details, can not quick-replaceable.In addition, traditional rough boring cutter, the chip space offered between blade and tool rest body is little, and the space namely processed between blade and workpiece is little, and the chip produced during cutting is piled up instantaneously, reduces the space of processing, to hold chip few; Moreover chip area can not chip removal in time, and chip easily blocks blade, normally carrying out of impact processing.
Utility model content
For the problems referred to above, the utility model provides a kind of spatial accommodation increasing chip removal, and the rough boring cutter of the quick chip removal of energy.
The utility model is achieved through the following technical solutions: a kind of rough boring cutter, comprise tool rest body and cutter hub, described tool rest body is secured by bolts on cutter hub, described tool rest body upper part is provided with blade installation slot, described blade is fixed by screws in blade installation slot, the cylindrical of described tool rest body adopts two arc structure, and described tool rest body is split-type structural, and several split tool rests are fitted and are secured by bolts on cutter hub.
Tool rest body adopts split-type structural, and each split tool rest is all fixed with blade, and offers the chip space matched with it below blade, and be bolted with on cutter hub, single split tool rest is bolted, and adds the stability of cutter.There is chipping because of carelessness when adding man-hour, if this chipping occurs on one of them split tool rest, then taking off corresponding split tool rest and changing, split tool-apron structure is simple, light than entirety of weight, and replacement cost is low, and fast, normally carrying out of processing can be ensured.
The cylindrical of tool rest body adopts two arc design (i.e. the tool rest body part at blade back), is adding man-hour, is increasing the space between tool rest body and workpiece, is more conducive to cutting and chip removal.
Preferably, be provided with circular arc table top below described blade, described circular arc table top and tool rest body form a working chamber, and the side of this circular arc table top connects chip pocket.
Be provided with circular arc table top below blade, described circular arc table top and tool rest body form a working chamber, and this structure increases chip space, can hold the chip adding and produce man-hour as much as possible, have sufficient processing space, ensure the smooth of processing.
Preferably, described chip pocket comprises the root for chip removal, and described root is the arc groove of strip, and at the end rounding of arc groove.
Root similar " J " the shape structure of chip pocket, and the end of root adopts Rouno Cormer Pregrinding Wheel design.The structure of this chip pocket is more conducive to chip removal, realizes chip and is not detained at chip pocket, can not affect processing.
The utility model takes above-mentioned corrective measure, and its beneficial effect is remarkable: the utility model reduces expense on part replacement cost, is improved increasing chip space, and can accomplish quick chip removal, ensure carrying out smoothly of processing by structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is transverse sectional view;
Fig. 3 is the schematic diagram of chip area.
In figure, 1 is cutter hub, and 2 is tool rest bodies, and 21 is split tool rests, and 3 is bolts, and 4 is blades, and 5 is circular arc table tops, and 6 is chip pockets, and 7 is two arcs.
Detailed description of the invention
Contrast accompanying drawing to be below further described the utility model in conjunction with the embodiments:
Shown in Fig. 3, a kind of rough boring cutter, comprise tool rest body 2 and cutter hub 1, the cylindrical of tool rest body 2 adopts two arc (marking 7 in figure) structure, here tool rest body 2 is split-type structural, be made up of two split tool rests 21, two split tool rest 21 tops are provided with blade installation slot, blade 4 is fixed by screws in blade installation slot, and two split tool rests 21 are all fixed on cutter hub 1 by bolt 3, circular arc table top 5 is provided with below blade 4, circular arc table top 5 and tool rest body 2 form a working chamber, the side of this circular arc table top 5 connects chip pocket 6, chip pocket 6 comprises the part that is connected with circular arc table top 5 and the root for chip removal, wherein root is the arc groove of strip, the end rounding of this arc groove.
That more than enumerates is only specific embodiment of the utility model; obviously; the utility model is not limited to above embodiment, all distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, and all should belong to protection domain of the present utility model.
