Abstract
The utility model provides an insert sheet hob milling cutter, belongs to technique field of machinery, and is used for solving the problem that the fixing ring of the traditional insert sheet hob milling cutter is easy to fall. The insert sheet hob milling cutter comprises a knife body with an inner hole and a cutter blade with a cutting edge, wherein fixing rings are installed at two ends of the knife body, the cutter blade is installed on the knife body through the fixing rings, supporting platforms at two ends of the knife body are provided with inner cones with angles of 1.0-1.5 degrees, the inner wall of each fixing ring is provided with a taper matched with the inner cone on the supporting platform, and a wedge sheet is inserted between two adjacent cutting edges. The insert sheet hob milling cutter has the advantages of simple structure and long service life.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of hobboing cutter, particularly a kind of tipped gear hob.
Background technology
Empiecement hobboing cutter cutter hub support end platform in the past is a cylindrical structural, and the phenomenon that in use often has retainer plate to come off takes place, and becomes the blade loose or dislocation, gear hob can not normally be used, even scrap.Cause the main cause of this phenomenon to be: tipped gear hob is the gear cutting tool of processing modulus more than 9, and tool weight is big, and the endoporus precision is high, is not easy to install.The cutter hub brace table is two in the retainer plate contact-making surface to be faced directly, artificial when loading and unloading, knock retainer plate with weight and accomplishes loading and unloading, repeatedly knocks retainer plate is come off etc.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, proposed a kind of simple in structure, under the situation that does not increase production cost, improve the tipped gear hob in service life.
The purpose of the utility model can realize through following technical proposal: a kind of tipped gear hob; Comprise cutter hub with endoporus and blade with cutting edge; Retainer plate is installed at described cutter hub two ends and described blade is installed on the cutter hub through retainer plate; It is characterized in that; The angle that the brace table at described cutter hub two ends has inner cone and inner cone is 1.0 °～1.5 °, have on the described retainer plate inwall with brace table on the tapering that matches of inner cone, be embedded with key between the described two adjacent cutting edges.
Compared with prior art; This tipped gear hob forms self-locking through the tapering face of brace table and the tapering face of retainer plate; Make retainer plate being fixed on the brace table tightly; Under the situation of not destroying retainer plate, can't retainer plate be taken off, also can not come off because of repeatedly knocking, machining accuracy is high, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional structure sketch map of the utility model.
Fig. 3 is the partial structurtes sketch map of the utility model.
Among the figure, 1, cutter hub; 11, endoporus; 2, blade; 21, cutting edge; 3, retainer plate; 4, key.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
Like Fig. 1, Fig. 2 and shown in Figure 3; This tipped gear hob comprises cutter hub 1 with endoporus 11 and the blade 2 with cutting edge 21; At cutter hub 1 two ends retainer plate 3 is installed and blade 2 is installed on the cutter hub 1 through retainer plate 3; The angle that the brace table at cutter hub 1 two ends has inner cone and inner cone is 1.0 °～1.5 °, have on retainer plate 3 inwalls with brace table on the tapering that matches of inner cone, be embedded with key 4 between the two adjacent cutting edges 21.The best tapering of the inner cone on the brace table at cutter hub 1 two ends is 1.5 °.
This tipped gear hob forms self-locking through the tapering face of brace table and the tapering face of retainer plate 3; Make retainer plate 3 being fixed on the brace table tightly; Under the situation of not destroying retainer plate 3, can't retainer plate 3 be taken off; Also can not come off because of repeatedly knocking, machining accuracy is high, long service life.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
