Abstract
A hole-enlarging guide sleeve is characterized in that a steel ball and a retaining ring are arranged at the contact part of the hole-enlarging sleeve and the end face of an outer sleeve, a roller pin is arranged between the hole-enlarging sleeve and the inner circle and the outer circle of the outer sleeve, an elastic check ring and a spacer sleeve for a shaft are arranged at the lower port of the outer sleeve, and the hole-enlarging sleeve is made of 20Cr steel through carburizing and quenching. The utility model is used for the reaming direction in the spot facing work, reaming cover wearing and tearing are little, longe-lived, and the direction is nimble reliable, can reduction in production cost, improves the spot facing work precision.
Description
Technical field
The utility model relates to a kind of reaming fairlead that is used for hole processing.
Background technology
Machining industry, for generally reaming again after boring of the hole of having relatively high expectations, for guaranteeing precision, broad need be led by fairlead.Existing reaming fairlead is made of reaming cover and lining (overcoat), reaming cover endoporus and broad slide-and-guide, and the coefficient of sliding friction is big; The reaming cover is generally made by tin bronze, and the broad targeting part is generally the quenching of 45 steel, and both hardness differ bigger, and the reaming cover is easy to wear, and service life is short, not only increases production cost, also influences the hole machining accuracy.
The utility model content
The technical problems to be solved in the utility model provides that a kind of wearing and tearing are little, the life-span is long, can reduce production costs, and improves the reaming fairlead of hole machining accuracy.
The technical solution of the utility model is: reaming fairlead, packing reaming cover, overcoat, improvements are that reaming cover and overcoat end face contact site are provided with steel ball and keep circle, are provided with needle roller between the inside and outside circle of reaming cover and overcoat.
Overcoat lower port place is provided with and is contained in the circlip for shaft that reaming puts; The circlip for shaft top is provided with the spacer that is contained between reaming cover and the overcoat; Described needle roller has upper and lower two row; The reaming cover material is the 20Cr steel alloy, and there is carburized layer on the surface.
The utility model changes the reaming slide-and-guide into the guiding of rolling, coefficient of friction is little, and reaming is applied mechanically the 20Cr steel and is made through carburizing and quenching, hardness and cutter targeting part basically identical, and wearing and tearing greatly reduce, long service life, reduce production costs, the reaming cover rotates flexibly, and the counterpart gap is constant substantially, stable processing quality, the hole machining accuracy improves.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, reaming cover 3 is provided with steel ball 1 and keeps circle 2 with overcoat 7 end face contacts site, be provided with upper and lower two row needle rollers 5 between the inside and outside circle of reaming cover and overcoat, overcoat lower port place is provided with circlip for shaft 4, back-up ring top is provided with the spacer 6 that is contained between reaming cover and the overcoat, and reaming cover 3 is made through carburizing and quenching by the 20cr steel.
Claims (5)
1, a kind of reaming fairlead, packing reaming cover, overcoat is characterized in that reaming cover and overcoat end face contact site are provided with steel ball and keep circle, are provided with needle roller between the inside and outside circle of reaming cover and overcoat.
2,, it is characterized in that overcoat lower port place is provided with to be contained in the circlip for shaft that reaming puts by the described reaming fairlead of claim 1.
