Abstract
The utility model discloses a drilling and milling cutter for machining the inner side of the tail portion of a coupler trail frame. The drilling and milling cutter comprises a cutter handle and a cutter head, wherein the whole cutter head is in a shape of a drill bit, two blades are arranged at the lower end of the cutter head and form a symmetrical structure, and a deep groove is formed between the two blades. Two connecting parts are further arranged at the top end of the cutter handle. The cutter head of the drilling and milling cutter can perform milling while drilling during machining of the tail portion of the coupler trail frame according to the size R13, so that the abrasion amount of the drill bit is decreased, the machining speed is high, the efficiency is high, and the machining quality is good. In addition, fine tuning nuts are arranged on the connecting parts, calibration and adjustment can be performed at any time, and the machining accuracy is ensured.
Description
Technical field
The utility model relates to the instrument that a kind of machining is used, and is a kind of for processing the brill milling cutter of hook tail frame afterbody inner side specifically.
Background technology
Forging hook tail frame is one of critical component of railway freight-car, is mainly used in the connection of railway freight-car coupler coupler buffering device.13B type forging hook tail frame is for the various lorry of hook load-carrying 60t level and extraordinary lorry.Railway freight-car forging hook tail frame is mainly comprised of framework and connecting plate, in the manufacture process of hook tail frame, according to national standard, hook tail frame has the size of a R13 in the inner side of afterbody, because its shape is special, and there is again a gradient, process this size more difficult, this size of traditional processing is by bit drills, larger to the wear extent of drill bit when boring, speed is slow, and efficiency is low, cost is high, nor can guarantee crudy.
Utility model content
Utility model object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of working (machining) efficiency high, and the quality of production is good, for processing the brill milling cutter of hook tail frame afterbody inner side.
For achieving the above object, the technical solution adopted in the utility model is a kind of for processing the brill milling cutter of hook tail frame afterbody inner side, comprise handle of a knife and cutter head, described cutter head integral body is drill-shape, the lower end of described cutter head is provided with two blades, described two blades are symmetrical structure, and between two blades, form a dark groove; The top of described handle of a knife is also provided with two connectors.
As preferably, the degree of depth of described dark groove is 60mm, and wide is 16mm.
As preferably, on described connector, be also provided with fine-tuning nut.
Beneficial effect: the utility model provides a kind of for processing the brill milling cutter of hook tail frame afterbody inner side, cutter head of the present utility model can be inside processing hook tail frame afterbody during this size of R13 limit bore side milling, carry out simultaneously, to reduce the wear extent of drill bit, processing speed fast, efficiency is high, processing quality good, and fine-tuning nut is set on connector, and adjust in school at any time, guarantees machining accuracy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of for processing the brill milling cutter of hook tail frame afterbody inner side, comprise handle of a knife 1 and cutter head 2, described cutter head 2 integral body are drill-shape, the lower end of described cutter head 2 is provided with two blades 3, and described two blades 3 are symmetrical structure, and between two blades 3, forms a dark groove 4; The top of described handle of a knife 1 is also provided with two connectors 5.
Wherein, the degree of depth of described dark groove 4 is 60mm, and wide is 16mm.
Wherein, on described connector 5, be also provided with fine-tuning nut 6.
Adopt technique scheme, cutter head of the present utility model can bore side milling in limit when this size of processing R13, carries out simultaneously, to reduce the wear extent of drill bit, the speed of processing is fast, efficiency is high, the quality of processing is good, and fine-tuning nut is set on connector, adjust in school at any time, guarantees machining accuracy.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
