Abstract
The invention relates to a novel hilt, and belongs to the technical field of machining tools. The novel hilt comprises a knife head and a knife bar, wherein the knife head is conical in shape, the inclination angle of the knife head is 13-20DEG, and the diameter of the end portion of the knife head far from the knife bar is largest. The knife head is provided with empty avoiding surfaces comprising two first empty avoiding surfaces and two second empty avoiding surfaces, and each two crossed empty avoiding surfaces form a recess portion, wherein each of the first empty avoiding surfaces is provided with an arc, and the radius of the arc is 32-35mm; and each of the second empty avoiding surfaces is provided with a blade placing surface, a blade fixing surface, an empty avoiding groove and a blade mounting hole. The empty avoiding groove is arranged at the crossing position of two blade fixing surfaces, the blade mounting hole is arranged on the blade placing surface, and the blade mounting hole is a screwed hole. The novel hilt has the advantages of simple structure, effective utilization of waste blades, durability, high processing efficiency, cost saving and the like.
Description
Technical field
The present invention relates to the frock tool technical field of machining, relate in particular to the milling cutter hilt that a kind of novel machining center uses.
Background technology
Along with Chinese economic development, the tradition manufacturing industry progressively changes to advanced manufacturing industry, and the use of CNC in advanced manufacturing industry is frequent day by day, so-called CNC is the abbreviation of " Computer Numerical Control ", i.e. " computer numerical control (CNC) lathe " (being called for short " Digit Control Machine Tool ").
Cutter plays an important role in CNC uses, and cutter comprises the blade of direct processing work and blade is fixedly installed in hilt on the CNC cutter platform.Wherein, blade comprises carbide chip, ceramic tip etc.Blade is consumable accessory, and the price comparison height.And when the CNC processing work, only use the processing limit of blade, if the processing limit of blade is damaged, whole blade all possibly can't be used.But, can guarantee effectively that by the structure of hilt the service life of blade is more of a specified duration.So, seek simplicity of design, can effectively utilize blade, improve the service life of blade and guarantee machining accuracy and the hilt of efficient is the problem that practitioner, technical staff and researcher constantly pursue.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of novel hilt, this hilt has simple in structure, can effectively utilize useless blade, durable in use, characteristics such as working (machining) efficiency is high, saving cost.
The objective of the invention is to be achieved through the following technical solutions:
A kind of novel hilt comprises cutter head and knife bar, and cutter head is coniform, the inclination angle of cutter head be 13 the degree to 20 the degree, cutter head is away from the end diameter maximum of knife bar; Described cutter head is provided with empty avoiding face, and two crossing empty avoiding faces form a recess, and wherein, the first empty avoiding face is provided with circular arc, and the radius of circular arc is that 32mm is to 35mm; The second empty avoiding face is provided with blade placed side, blade stationary plane, avoiding hollow groove and blade installing hole; Avoiding hollow groove is located at the position that two blade stationary planes intersect, and the blade installing hole is located on the blade placed side, and described blade installing hole is screwed hole.
Described cutter head inclination angle is that 14 degree are to 16 degree.
The arc radius of the described first empty avoiding face is that 33mm is to 34mm.
Described cutter head is provided with 4 empty avoiding faces, and forms two centrosymmetric recesses in the end of cutter head.
The end of described tool bit diameter maximum is recessed by export-oriented center, and the inclination angle is that 4 degree are to 6 degree.
Inside recessed inclination angle, described cutter head end is 5 degree.
The maximum end of described tool bit diameter outer rim is provided with chamfering, and the radius of chamfering is that 1.2mm is to 1.8mm.
The radius of the maximum end of described tool bit diameter outer rim chamfering is that 1.4mm is to 1.6mm.
By technique scheme of the present invention, novel hilt of the present invention has simple in structure, can effectively utilize useless blade, durable in use, effects such as working (machining) efficiency is high, saving cost.
Description of drawings
Fig. 1 is one embodiment of the present invention structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of novel hilt comprises cutter head 2 and knife bar 1, and cutter head 2 is coniform, the inclination angle scope of cutter head 2 taper seats 21 be 13 the degree to 20 the degree, preferred 14 the degree to 16 the degree.Cutter head 2 is away from the end diameter maximum of knife bar 1, and just the diameter at the position that is connected with knife bar 1 of cutter head 2 is less than cutter head 2 away from the end diameter of knife bar 1.
As shown in Figure 1, be provided with 4 empty avoiding faces at cutter head 2, and form two centrosymmetric recesses in the end of cutter head 2.So-called symmetrical recess setting refers to second recess and has the structure same with first recess, and is symmetrical arranged in the position.Like this two blades can be installed simultaneously, be convenient to the raising of working (machining) efficiency
When arranging, the end of cutter head 2 diameter maximums is recessed by export-oriented center, and namely the outer end 26 of cutter head 2 maximum gauges is recessed gradually to centerline direction.The inclination angle scope of concave surface be 4 the degree to 6 the degree, be preferably 5 the degree.
Simultaneously, the maximum end of cutter head 2 diameters outer rim is provided with chamfering 27, and the radius of chamfering 27 is that 1.2mm is to 1.8mm.Preferred 1.4mm is to 1.6mm.
Knife bar 1 is provided with mounting groove 11 and installation base 12 away from the end of cutter head 2, is used for whole hilt is fixed in the cutter platform of CNC.
By technique scheme of the present invention, novel hilt of the present invention has simple in structure, can effectively utilize useless blade, durable in use, effects such as working (machining) efficiency is high, saving cost.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
