Description
Technical field
The utility model relates to machine tool technical field, is specifically related to a kind of lathe tools.
Background technology
Regular turning tool is all generally one-body molded, is generally used for the outer surface of processing work.
When the surface of the work more complicated of processing, usually need to change different lathe tools and carry out machining, the replacing of cutter is cumbersome, and working (machining) efficiency is low.
When machining, the point of a knife of lathe tool and cutting edge bear larger power, and the stress surface of point of a knife and cutting edge is less, in working angles, the phenomenon of cutting edge explosion often occur.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the lathe tools that a kind of structure is simple, can bear larger power.
Realize the technical solution of the utility model as follows:
A kind of lathe tools, comprise handle of a knife and cutter head, the central authorities of the head end of described handle of a knife are provided with screwed hole, described cutter head comprises installation portion and cutting portion, installation portion is provided with the counterbore axially arranged, counterbore and screwed hole isometrical, cutter head is fixedly connected with the head end of handle of a knife by bolt, cutting portion is arranged on the one end away from handle of a knife on installation portion, the sidewall of cutting portion and installation portion is connected to form sickleshaped structure, described cutting portion comprises the first side wall, second sidewall, 3rd sidewall, the first side wall, 3rd arc-shaped transition between sidewall and the sidewall of installation portion, second sidewall and the first side wall arc-shaped transition, obtuse angle is pressed from both sides between the first side wall and the second sidewall, second sidewall is crossing with the 3rd sidewall, acute angle is pressed from both sides between second sidewall and the 3rd sidewall, described 3rd sidewall is arcwall face, on 3rd sidewall, nearly second sidewall end establishes main cutting edge, on second sidewall, nearly 3rd sidewall end establishes front cutting edge.
Further, the perisporium of described handle of a knife head end is provided with stopper slot, and stopper slot is uniformly distributed around the axis of handle of a knife, and the one end near handle of a knife on described cutter head is provided with the limited block suitable with stopper slot.
Have employed above-mentioned scheme, cutter is in cutting process, and cutter head and cutting portion can bear larger power, improves cutting-tool's used life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 exploded view;
In figure, 1 is handle of a knife, and 2 is cutter head, and 3 is screwed hole, and 4 is installation portion, and 5 is cutting portion, and 6 is counterbore, and 7 is bolt, and 8 is the first side wall, and 9 is the second sidewall, and 10 is the 3rd sidewall, and 11 is stopper slot, and 12 is limited block.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1, 2, a kind of lathe tools, comprise handle of a knife 1 and cutter head 2, the central authorities of the head end of described handle of a knife are provided with screwed hole 3, described cutter head comprises installation portion 4 and cutting portion 5, installation portion and cutting portion one-body molded, installation portion is provided with the counterbore 6 axially arranged, counterbore and screwed hole isometrical, cutter head is fixedly connected with the head end of handle of a knife by bolt 7, cutting portion is arranged on the one end away from handle of a knife on installation portion, the sidewall of cutting portion and installation portion is connected to form sickleshaped structure, described cutting portion comprises the first side wall 8, second sidewall 9, 3rd sidewall 10, the first side wall, 3rd arc-shaped transition between sidewall and the sidewall of installation portion, second sidewall and the first side wall arc-shaped transition, obtuse angle is pressed from both sides between the first side wall and the second sidewall, second sidewall is crossing with the 3rd sidewall, acute angle is pressed from both sides between second sidewall and the 3rd sidewall, described 3rd sidewall is arcwall face, on 3rd sidewall, nearly second sidewall end establishes main cutting edge, on second sidewall, nearly 3rd sidewall end establishes front cutting edge.
Adopt cutter head described in the utility model to carry out machining, the cutting portion of cutter head can bear larger power, and not easily burst apart in working angles, cutting-tool's used life is greatly enhanced.When cutter head is impaired, directly can change cutter head, and not need whole cutter to disassemble from toolframe; The surface of the work of processed complex, directly changes different cutter heads and just can carry out machining.Described 3rd sidewall is arcwall face, can be convenient to the eliminating of the chip that Tool in Cutting processing produces.
Further, the perisporium of described handle of a knife head end is provided with stopper slot 11, and stopper slot is uniformly distributed around the axis of handle of a knife, and the one end near handle of a knife on described cutter head is provided with the limited block 12 suitable with stopper slot.Cooperatively interacting of stopper slot and limited block, thus realize spacing to the radial direction of cutter head, cutter head is by the head end of locked with bolts at handle of a knife, and cutter head is by axial limiting, and so, cutter head can be tightly fixed on the head end of handle of a knife.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
