Abstract
The utility model discloses special cutter for machining a slender graphite rod. The cutter comprises a clamping handle and a cutter holder fixedly connected with the clamping handle. The cutter holder is in a disc shape; through holes allowing the graphite slender rod to pass are formed in the center of the cutter holder and the center of the clamping handle; multiple outer ring turning tools are assembled on the outer disc face of the cutter holder, arranged in the radial direction of the outer disc face and evenly distributed in the circumferential direction of the outer disc face. The cutter is simple in structure, is clamped at a tailstock and is precisely positioned, the method that supporting and cutting are carried out simultaneously through two cutting heads or three cutting heads is adopted, and the cutter can be used for machining various slender graphite rods of different diameters.
Description
Technical field
The utility model relates to a kind of cutting tool, and particularly a kind of dedicated tool for processing graphite thin bar series products, belongs to Machining Technology for Cutting field.
Background technology
In the industries such as silicon chip film-coated production, need to use a kind of graphite boat, this graphite boat is assembled by graphite boat sheet, the little block part of graphite, graphite bars and ceramic bar.Wherein, adopt conventional stock class parts machining process, during graphite bars is processed, although use the auxiliary equipment such as follow-rest, because graphite material is frangible, and it is serious in processing, to tremble, therefore graphite bars very easily ruptures, general skilled craftsman's per tour (8 hours) at most only can be processed 10 graphite bars, so working (machining) efficiency is extremely low, and machining accuracy is very poor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of dedicated tool for processing graphite thin bar, has advantages of that working (machining) efficiency is high and machining accuracy is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
For a dedicated tool for processing graphite thin bar, comprise grip shank and the knife rest being fixedly connected with grip shank; Knife rest is disc; The center of knife rest and grip shank offers the through hole that graphite thin bar is passed through; In the cylindrical card of knife rest, be equipped with a plurality of billmpse tools, the footpath that a plurality of billmpse tools are all located at cylindrical card makes progress and being circumferentially uniformly distributed along cylindrical card.
Wherein, the number of described billmpse tool is three.
Wherein, the outer surface of described grip shank is conical, and its tapering is No. 4 taperings of Mohs.
Wherein, the cylindrical card of described knife rest is provided with a plurality of lathe tool fitting recess, and a plurality of billmpse tools are fixed by screws in respectively in lathe tool fitting recess.
Wherein, in the through hole of the joint portion of described knife rest and grip shank, be equipped with guiding core retainer plate; The internal diameter of guiding core retainer plate is than the slightly larger in diameter of the graphite round bar being processed into, and the outer surface of guiding core retainer plate is conical, and its tapering is metric system 1:20 tapering.
Wherein, described billmpse tool is 75 ° of billmpse tools, and its parameter is: 75 ° of tool cutting edge angles, 20 ° of auxiliary angles, 2 ° of main cutting edge anterior angles, 10 ° of relief angles, 2 ° of front cutting edge anterior angles, 10 ° of relief angles, 1.993 ° of cutting edge inclinations.
The beneficial effect that adopts technique scheme to produce is:
The utility model passes through the analysis of conventional graphite bars processing industry and research, while is in conjunction with the special working properties of graphite, made dedicated tool, grip shank by this cutter by taper is fixed on tailstock tool, use 2 or 3 lathe tools, use and support and cut the processing method of simultaneously carrying out, successfully solved a difficult problem for conventional graphite bars processing technology graphite bars easy fracture, not only improve the process velocity of graphite bars, guaranteed the machining accuracy of product simultaneously.
The utility model is simple in structure, tailstock clamping, and accurate positioning, is adopted and is supported and cut the method for simultaneously carrying out by Double-cutter head or three cutter heads, can be used for processing the elongated graphite bars product of various different-diameters.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the utility model is a kind of dedicated tool for processing graphite thin bar, comprises grip shank 1 and the knife rest 2 being fixedly connected with grip shank 1; The outer surface of grip shank 1 is conical, and its tapering is No. 4 taperings of Mohs; In the through hole of the joint portion of knife rest 2 and grip shank 1, be equipped with guiding core retainer plate 5; The outer surface of guiding core retainer plate 5 is conical, and its tapering is metric system 1:20 tapering; The internal diameter of guiding core retainer plate 5 is than the slightly larger in diameter of the graphite round bar being processed into, guiding core retainer plate 5 can play the effect of supporting workpiece, advances, to avoid long rod workpieces to add the problem of being out of shape cutter relieving man-hour with cutter, and 5 guiding core retainer plates are replaceable, to process sizes graphite bars.Knife rest 2 is disc; The center of knife rest 2 and grip shank 1 offers the through hole that graphite thin bar is passed through; In the cylindrical card of knife rest 2, be equipped with a plurality of billmpse tools 3, the footpath that a plurality of billmpse tools 3 are all located at cylindrical card makes progress and being circumferentially uniformly distributed along cylindrical card.The number of billmpse tool 3 is preferably three, three uniform clampings of lathe tool, and three amount of feeding of a stroke, when reducing turning amount, have increased operating efficiency.The cylindrical card of knife rest 2 is provided with a plurality of lathe tool fitting recess, and a plurality of billmpse tools 3 are fixed in lathe tool fitting recess by screw 4 respectively.
As shown in Figure 4, billmpse tool 3 of the present utility model is 75 ° of billmpse tools, and its parameter is: 75 ° of tool cutting edge angles, 20 ° of auxiliary angles, 2 ° of main cutting edge anterior angles, 10 ° of relief angles, 2 ° of front cutting edge anterior angles, 10 ° of relief angles, 1.993 ° of cutting edge inclinations.
