Description
Technical field
The utility model relates to a kind of carbide alloy guider, is specifically related to a kind of deep hole machining carbide alloy guider, belongs to field of machining.
Background technology
Deep hole machining is owing to being semiclosed or carry out close to closing under working condition, thus a processing difficult problem (tubesheet holes etc. as on nuclear steam turbine train condenser tube sheet) is acknowledged as, for guaranteeing deep hole machining quality, fairlead is selected to be one of measure.Existing fairlead centering effect is poor, and service precision is low, affects crudy.
Utility model content
The utility model is poor for solving existing fairlead centering effect, and service precision is low, affects the problem of crudy, and then proposes a kind of deep hole machining carbide alloy guider.
The utility model is the technical scheme taked that solves the problem: the utility model comprises drill bushing and positioning sleeve, drill bushing is connected to form successively by linkage section cylinder and lead segment cylinder head and the tail, the first through hole is had in linkage section cylinder, the second through hole is had in lead segment cylinder, first through hole is communicated with the second through hole, third through-hole is had in positioning sleeve, third through-hole is connected to form successively by the first rectangular section, the first conical section, the second rectangular section head and the tail, and linkage section cylinder is inserted in the second rectangular section.
The beneficial effects of the utility model are: the utility model not only increases guiding accuracy, also substantially increase fairlead service life; The utility model improves former in adjective-centre structure, Integral alloy steel matter fairlead, substantially increases centering effect and service life.This fairlead adopts Hardmetal materials drill bushing and alloy steel material positioning sleeve assembling integrative-structure pattern, not only increases guiding accuracy, also substantially increases fairlead service life.The drill bushing end face of this fairlead is designed with the V-type raised face (add and contact with workpiece end face man-hour) of an annular, not only plays boring certralizing ability, but also plays sealing function, prevent cutting fluid from revealing, ensure that deep hole machining quality.
Accompanying drawing explanation
Fig. 1 is main sectional view of the present utility model, and Fig. 2 is the main sectional view of drill bushing, and Fig. 3 is I place enlarged drawing in Fig. 2, and Fig. 4 is the main sectional view of positioning sleeve.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 to Fig. 4 illustrates present embodiment, described in present embodiment, a kind of deep hole machining carbide alloy guider comprises drill bushing 1 and positioning sleeve 2, drill bushing 1 is connected to form successively by linkage section cylinder 1-1 and lead segment cylinder 1-2 head and the tail, the first through hole 1-1-1 is had in linkage section cylinder 1-1, the second through hole 1-2-1 is had in lead segment cylinder 1-2, first through hole 1-1-1 is communicated with the second through hole 1-2-1, third through-hole 2-1 is had in positioning sleeve 2, third through-hole 2-1 is by the first rectangular section 2-1-1, first conical section 2-1-2, second rectangular section 2-1-3 head and the tail connect to form successively, linkage section cylinder 1-1 is inserted in the second rectangular section 2-1-3.
Detailed description of the invention two: composition graphs 1 to Fig. 4 illustrates present embodiment, first through hole 1-1-1 of a kind of deep hole machining carbide alloy guider described in present embodiment is connected to form successively by the 3rd rectangular section and the second conical section head and the tail, and described second conical section is identical with the tapering of the first conical section 2-1-2.
The technique effect of present embodiment is: so arrange, and is convenient to drill bit to introduce in drill bushing 1, and adds centering and sealing function when playing boring man-hour.Other composition and annexation identical with detailed description of the invention one.
Detailed description of the invention three: composition graphs 1 to Fig. 4 illustrates present embodiment, described in present embodiment, the edge of a kind of second through hole 1-2-1 of deep hole machining carbide alloy guider is provided with slope 1-2-2.Other composition and annexation identical with detailed description of the invention one.
