Abstract
The utility model provides a cylinder graduating tool for a non-rotative machine. The cylinder graduating tool is provided with a cylinder main body. A tool bit is arranged at one end of the cylinder main body, and the tool bit is provided with a blade, a tool nose, an anterior angle and a relief angle. The front surface of the shape of the tool bit is a taper angle, and the tool nose deviates from the center line of the cylinder main body. The tool bit of the cylinder graduating tool for the non-rotative machine is provided with appearance geometrical angles with unique design, and used materials have the advantages of being simple in source, low in cost, long in service life, easy to cut and sharpen, high in precision of processing, clear and smooth in lines, not high in demands of a clamped machine tool and the like. The cylinder graduating tool is especially applicable to a common machine tool to enable the common machine tool to process graduated lines which are high in appearance quality and high in precision. During a processing practice, the processing precision of the cylinder graduating tool can reach+/- 1.5', and the processing of the graduated lines can be realized in a plane, an inclined plane and a circumference.
Description
Technical field
The utility model relates to a kind of non-rotating machine cylinder scribing cutter, is particularly useful for common milling machine or boring machine, can process the graduation mark of high accuracy, apperance quality.
Background technology
The processing of the part graduation mark of precision equipment often belongs to high-precision machining, for example in the testing equipment required precision between dial two grooves generally can reach ± 2 '.Numerical controlled engraving and milling device is fit to small lot, part that the groove number is many, but for then seem underaction and greatly improved processing cost of numerical controlled engraving and milling device in the few situation of the single-piece production of frequent appearance or groove number.Carry out groove so generally adopt at present at machine tool dress rotation line carver or the non-rotating line carver of square handle, the rotation line carver in working order lower employed lathe rotating speed is required very high, the defective such as point of a knife frangibility when having tool sharpening difficulty, groove; Although handle non-rotating line carver in side's has been avoided the duty of High Rotation Speed, the clamping difficulty must cooperate the self-control special tool-post to use, and not easy to operate, the production qualification rate is low, therefore is necessary to improve.
The utility model content
The technical problem that the utility model solves: be the problem such as overcome groove processing cost height, operating difficulties, the production cycle is long, qualification rate is low, the utility model provides a kind of non-rotating machine cylinder scribing cutter, have that sharpening is simple, easy to operate, graduating accuracy is high, the excellent characteristics of presentation quality, solved well an above-mentioned difficult problem.
The technical solution adopted in the utility model: non-rotating machine cylinder scribing cutter, have cylindrical body, described cylindrical body one end is cutter head, and described cutter head has blade, point of a knife, anterior angle and relief angle, described cutter head shape front is cone angle, and point of a knife and cylindrical body center line depart from.
Further, described point of a knife and cylindrical body center line depart from 1.5mm～2mm.
Further, the anterior angle of described cutter head is 3 °～5 °.
Further, the cone angle of described cutter head is 60 °.
Further, the relief angle of described cutter head is 20 °～22 °.
Further, the point diameter of described cutter head is 0.02mm.
Further, the diameter of described cylindrical body is 8mm～12mm.
Further, described cutter head also comprises auxiliary angle.
The utility model compared with prior art cutter head has how much angles of the unique profile of design, material therefor source is simple, cost is low, long service life, easily sharpening, the processing graduating accuracy is high, svelteness is smooth, to characteristics such as the lathe of clamping are less demanding, be particluarly suitable for using on the machine tool, common machine tooling apperance quality, high accuracy groove are become a reality.In machining Practice, this tool sharpening precision can reach ± 1.5 ', no matter on the plane, inclined-plane, periphery processing groove can both realize.

Fig. 2 is the utility model structural front view;
Fig. 3 is the utility model structure side view.
The specific embodiment
Below in conjunction with accompanying drawing 1-3 a kind of embodiment of the present utility model is described.
Non-rotating machine cylinder scribing cutter, has cylindrical body 1, described cylindrical body 1 one ends are cutter head, described cutter head has blade 4, point of a knife 3, anterior angle 2 and relief angle 5, described cutter head shape front is cone angle 7, to carry out groove as example at the Steel material piece surface, cylindrical body 1 is Φ 8mm～Φ 12mm column structure, other end cutter head is shaped as: the front is 60 ° of cone angles 7, point of a knife 3 is crossed center line 1.5mm～2mm, and the anterior angle 2 of cutter head is 3 °～5 °, and 7 liang of equilateral symmetries of cone angle inwardly close up until cross to a line in outer peripheral edges, the relief angle 5 that self-assembling formation is 20 °～22 ° and blade 4, all the other are auxiliary angle 6.The cutter point of a knife 3 diameter minimums of this structure can be 0.02mm, and close to point, the blade 4 of edge of a knife bottom is sharp, thereby the svelteness that adopts this line carver to carve is smooth, precision is high.Grope through practice, select 60 ° of cone angles 7 can guarantee the intensity of cutter, anterior angle 2 be 3 °～5 ° delivery ratios that can make smear metal smoothness reduce simultaneously the cutter loss, 20 °～22 ° relief angle 5 has reduced the chatter that produces in the friction of cutter and the processing, and auxiliary angle 6 can avoid cutter and other workpiece to collide.The structure of this cutter can guarantee that smear metal is smooth, sharpness and the intensity of the edge of a knife reach optimization.
Work in-process, cylindrical body 1 one ends are clamped on plain-milling machine or the boring spindle, under electroless state, shake the lathe handle, make machine tool chief axis make radially irrotational motion, cutter hub is along with machine tool chief axis motion reaches purpose at piece surface cutting groove, use flexible, easy and simple to handle, cutter life is long.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, so all equivalences of being done with the described content of the utility model claim change, all should be included within the utility model claim scope.
