Abstract
The utility model discloses a hub drill, which comprises a hilt and a knife. Blades, edges, a front knife surface and a bottom edge are arranged on the knife, and an arc-shaped chip breaker groove is disposed on the front knife surface of the knife. The blades and the edges on two sides of the hub drill are in asymmetrical design, so that vibration of the hub drill during hole drilling can be avoided effectively, surface vibration grains, black hole walls and knife sticking during processing of bolt holes can be prevented, the arc-shaped chip breaker groove is arranged on the front knife surface of the knife so that cutting resistance generated by the hub drill during processing can be reduced, surface smoothness of drilled holes is increased, processing efficiency is improved, and the quality of the drilled holes is enhanced.
Description
Technical field
The utility model relates to a kind of brill cutter, and particularly a kind of wheel hub that is used for processing automobile aluminium alloy wheel hub bolt hole bores.
Background technology
In the production process of automobile, the bolt hole on the aluminium alloy wheel hub of automobile all is to adopt wheel hub to creep into row processing.But employed various wheel hubs bore in the industry at present, the land that wheel hub bores both sides is symmetrical, in the process of the bolt hole on wheel hub, vibrations in various degree can appear when wheel hub is drilled in work, turn black, glue phenomenons such as cutter with regard to surface shake line, the hole wall that occurs on the bolt hole of feasible processing in various degree like this, influence attractive in appearance, the serious words of bolt hole even can have influence on the quality of product, and adopt existing wheel hub to be drilled in the boring procedure, cutting resistance is bigger, make that the working (machining) efficiency of boring is not high, production efficiency is affected.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides and a kind ofly can improve working (machining) efficiency, and the wheel hub that can avoid again surface shake line, hole wall blackout and sticking cutter phenomenon occurring when the processing bolt hole bores.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of wheel hub bores, and comprises handle of a knife and cutter hub, and described cutter hub is provided with land, cutting edge, rake face and shear blade, and the rake face of described cutter hub is provided with the circular arc chip-breaker.
Preferably, the cutting edge of described cutter hub both sides is asymmetric.
Preferably, the land of described cutter hub both sides is asymmetric.
Further, the one-sided downward mill of the cutting edge of described cutter hub downside is low.
Preferably, the shear blade of described cutter hub and cutting edge are provided with chip-breaker.
Technique scheme has following beneficial effect: land and cutting edge that this wheel hub bores both sides adopt asymmetric design, can avoid effectively that wheel hub gets out existing vibrations in boring procedure, prevent from when the processing bolt hole, to occur surface shake line, hole wall blackout and sticking cutter phenomenon, on the rake face of cutter hub, be provided with the circular arc chip-breaker, can reduce wheel hub and be drilled in the cutting resistance that produces in the process, improve boring surface fineness, improve working (machining) efficiency, improve the quality of boring.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 bores the structural representation of a side for the utility model wheel hub.
Fig. 2 bores the structural representation of another side for the utility model wheel hub.
Fig. 3 is the enlarged diagram at A place among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, 3, this wheel hub bores and comprises handle of a knife 1 and cutter hub 2, cutter hub is provided with land 3,4, cutting edge 5,6 and shear blade, wherein respectively be provided with circular arc chip-breaker 7 on the shear blade of cutter hub 2 and the cutting edge 5,6, the shear blade of cutter hub 2 is provided with two chip-breakers 8, and the cutting edge 5 of cutter hub upside is asymmetric with the cutting edge 6 of downside, the land 3 of cutter hub upside is asymmetric with the land 4 of downside, and the one-sided downward mill of the cutting edge 41 of downside is low.
More than a kind of wheel hub that the utility model embodiment is provided bore and be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
