Abstract
The utility model discloses a spot face countersink, which comprises a countersink body and carbide blades located at the front part of the countersink body. The countersink is characterized in that a countersink head is arranged on the countersink body, the carbide blades are annularly mounted on the front end surface of the countersink head, a positioning core is arranged in the center of the front end surface of the countersink head, an antifriction bearing is mounted at the front end of the positioning core, and the part of the antifriction bearing extending out of the countersink head is higher than the parts of the carbide blades extending out of the countersink head. The spot face countersink provided by the utility model has the advantages of simple structure, convenient use, low cost, long service life and high work efficiency.
Description
Technical field
The utility model relates to the cutter that uses in a kind of machining, particularly relates to a kind of spot face countersink.
Background technology
As engine cylinder-body, wherein there are a plurality of holes need carry out spot face processing in all kinds of auto parts.Traditional processing method is with the special-purpose countersink spot facing in the high-speed steel plane of band fixed guide, the durability of cutter low (every cutter can only be processed and be no more than 200) like this, and targeting part and cutter rotate together, wear and tear especially easily and cause the scuffing of workpiece bottom outlet, reduce the surface smoothness of workpiece bottom outlet; And not thorough to the processing component back chipping, cause the waste of cutter again.
Summary of the invention
The utility model is finished in order to solve deficiency of the prior art, the purpose of this utility model provide a kind of simple in structure, easy to use, cost is low, the life-span is long, high efficiency the spot face countersink.
A kind of spot face countersink of the present utility model, comprise cutter hub and the carbide chip that is positioned at the cutter hub front end, it is characterized in that: establish cutter head on the described cutter hub, described insert ring is located on the cutter head front end face, described cutter head front end face central authorities are provided with positioning core, described positioning core front end is provided with rolling bearing, and the height that described rolling bearing protrudes described cutter head protrudes the height of described cutter head greater than described blade.
A kind of spot face countersink of the present utility model can also be:
Described rolling bearing interference fit edge is placed in described positioning core front end.
Described blade is welded on the described cutter head.
The cutter hub that described cutter hub is made for the 45# steel.
A kind of spot face countersink of the present utility model, in terms of existing technologies, owing to establish cutter head on its described cutter hub, described insert ring is located on the cutter head front end face, described cutter head front end face central authorities are provided with positioning core, described positioning core front end is provided with rolling bearing, and the height that described rolling bearing protrudes described cutter head protrudes the height of described cutter head greater than described blade.Like this, owing to be provided with rolling bearing, and also when cutter head rotated, the guiding parts that rolling bearing and positioning core are formed did not rotate, and targeting part can not wear and tear and can not damage the scuffing bottom outlet simultaneously yet.Simultaneously can not waste cutter head yet, make that whole countersink cost reduces, the life-span is long, and guarantee that back chipping is thorough, high efficiency.

The specific embodiment
Below in conjunction with accompanying drawing Fig. 1 to Fig. 3 a kind of spot face countersink of the present utility model is described in further detail.
A kind of spot face countersink of the present utility model please refer to Fig. 1 to Fig. 3, comprises cutter hub 1 and the carbide chip 2 that is positioned at cutter hub 1 front portion, and this is the universal architecture of all countersinks.Countersink of the present utility model is, establish cutter head 3 on the described cutter hub 1, described blade 2 rings are located on cutter head 3 front end faces, described cutter head 3 front end face central authorities are provided with positioning core 4, described positioning core 4 front ends are provided with rolling bearing 5, and described rolling bearing 5 protrudes the height of the height of described cutter head 3 greater than the described cutter head 3 of described blade 2 protrusions.Like this, owing to be provided with rolling bearing 5, and also when cutter head 3 rotated, the guiding parts that rolling bearing 5 and positioning core 4 are formed did not rotate, and targeting part can not wear and tear and can not damage the scuffing bottom outlet simultaneously yet.Simultaneously can not waste cutter head 3 yet, make that whole countersink cost reduces, the life-span is long, and guarantee that back chipping is thorough, high efficiency.
A kind of spot face countersink of the present utility model please refer to Fig. 1 to Fig. 3, and described rolling bearing 5 interference fit edge is placed in described positioning core 4 front ends.Rolling bearing 5 combines more firm with positioning core 4 like this.Described blade 2 is welded on the described cutter head 3, in addition, is arranged with dust cover on the rolling bearing, and the effect of dust cover is on preventing that ash from falling.Weld more firmly, can not drop when guaranteeing the countersink spot-facing.The cutter hub 1 that described cutter hub 1 is made for the 45# steel.Cutter hub 1 is durable.
Above-mentionedly only several specific embodiments in the utility model are illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
