Fig. 2 is the front view of the cutter that provides of the utility model.
Fig. 3 is the schematic diagram of the cutter that provides of the utility model.
The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As Figure 1-3, the utility model provides a kind of cutter, the cutter assembly 2 that it comprises handle of a knife 1 and is arranged on handle of a knife 1 lower end and is connected with handle of a knife 1; Cutter assembly 2 comprises fixed leg 21 and is fixed on some blades 22 on fixed leg 21 surfaces; Blade 22 comprises fixed part 23 and on-fixed section 25, and fixed part 23 is fixedly connected with fixed leg 21, and on-fixed section 25 comprises cutting face, bottom surface; Outer rim place in the cutting face is provided with blade 26.
The utility model is not done specific (special) requirements to the material of cutter, as long as it satisfies the processing request of workpiece, the metal that preferred hardness is high; For example: manganese alloy, tungsten alloy.
Wherein handle of a knife 1 is structure as a whole with cutter assembly 2, also can be Split type structure; Preferably, it is structure as a whole, and adopts integrative-structure can prevent cutter at work, and under the effect of external force, losing efficacy in the junction, causes tool damage or even fracture, affects the efficient of workpiece processing.
The utility model is not done specific (special) requirements to the shape of handle of a knife 1, as long as can be pressed from both sides surely by lathe and fix; Can for cylindrical, also can for square, can also be rhombus; Preferably, handle of a knife be shaped as cylindrical.
The arrangement mode of the preferred blade 22 of the utility model is: blade 22 is arranged along clockwise direction or counterclockwise and with handle of a knife 1 pivot twist; Can improve like this precision of Tool in Cutting.
Preferably, the Length Ratio of the length of handle of a knife 1 and cutter assembly 2 is 1.5:1 ~ 3:1; The length of cutter assembly 2 refers to: the length of blade 22.After such ratio can guarantee that handle of a knife 1 is fixed on the lathe, blade 22 can keep comparatively safe distance with lathe, can avoid, and blade 22 touches lathe, and causes blade 22 to damage, and prolongs the service life of blade 22.
Preferably, the radius ratio of the width of blade 22 and handle of a knife 1 is 1:1 ~ 1.5:1; The width of blade 22 refers to: the fixed part of blade 22 is to the air line distance of blade; Adopt this ratio can make the cutting effect of blade 22 more obvious, the stock-removing efficiency of blade 22 is higher.For the working durability that makes blade 22 longer, the utility model has increased the thickness of blade 22, preferably, its thickness is 3 ~ 5mm.
Be provided with dregs guiding groove 24 between two adjacent blades 22, the utility model is not done specific (special) requirements to the cross sectional shape of dregs guiding groove 24, can be square groove, can be circular trough yet; Preferably, it is circular trough; Adopt circular trough can make the fast landing of waste material that is cut on the workpiece, can so also can not reduce the time of waste material on labor cleaning's cutter at the too much waste material of cutter accumulation, improve the operating efficiency of cutter; Can also reduce the impact of scrap Workpiece Machining Accuracy, thereby improve the precision of workpiece.
Usually, the cutter of using on the three common axle lathes is single blade, and its blade is linear pattern, and this cutter can only be processed some workpiece that the right angle processing request is arranged; Workpiece that can not the finished surface complexity; For example: the processing cambered surface; If adopt the Digit Control Machine Tool of six axles, then can process with the Arbitrary 3 D face of workpiece by programming; But the price of six Shaft and NC Machining Test lathes is very high, adopts six Shaft and NC Machining Test machine tool processing workpieces can increase the processing cost of workpiece, and adopts six Shaft and NC Machining Test lathes that workpiece is processed, the long processing time of its single workpiece, and efficient is low; Simultaneously, adopt six Shaft and NC Machining Test lathes also to need to be equipped with the technical staff of professional skill and operative skill consummation, like this so that the processing cost of workpiece is higher.
The utility model provides a kind of cutter with circular arc blade 26, and the blade 22 on the cutter is at least two; Under the drive of cutter at lathe, when beginning rotation and work; Circular arc blade 26 on the blade 22 can carry out to workpiece the processing at right angle, and simultaneously, the middle bending part of circular arc blade 26 can carry out camber line processing to workpiece; Under the dual processing of circular arc blade 26, can obtain desirable workpiece.
Adopt cutter of the present utility model, both can satisfy the processing of workpiece simple flat surface, can satisfy again the processing of workpiece complex surface; The cutter that while the utility model provides can be installed on the three common axle lathes, like this, both can make the workpiece processing of machine tool effects on surface complexity, and then can replace six Shaft and NC Machining Test lathes; Thereby reduced greatly the processing cost of workpiece; And adopt at least two blades, can improve greatly the precision of workpiece.
A kind of three axis numerically controlled machine, it comprises the workpiece processing department; The workpiece processing department comprises cutter, the cutter that cutter provides for the utility model.Wherein the workpiece processing department is conventionally known to one of skill in the art, does not repeat them here.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
