Abstract
The invention discloses a combined central spindle device in the mechanical part processing, which comprises a central spindle and a shaft sleeve. One end of the central spindle is provided with a flange plate; the flange plate is provided with a limiting groove; the central spindle is provided with three diameter sections; the three diameter sections have different lengths; the three diameter sections adopts the following length arrangement that the lengths of the three diameter sections are gradually reduced from one end close to the flange plate to the other end; the three diameter sections of the central spindle are of a detachable connection structure; the shaft sleeve comprises two inner cone shaft sleeves and an outer cone shaft sleeve; each inner cone shaft sleeve is of a shape of a cylinder of which the center is provided with a through hole; the surface of an inner hole at one end of each inner cone shaft sleeve is a conical surface and is provided with an opening along the periphery; the outer cone shaft sleeve is of a shape of a hollow cylinder of which only one end is open; the outer surface of the open end is a conical surface and the end face of the other end is provided with a cone center hole; and the cone center hole is provided with a wear-resistant gasket along the hole edge. According to the invention, a processed part can be clamped and a processing error is reduced.
Description
Technical field
The present invention relates to a kind of mechanical device, particularly the combined core-axle device in a kind of machine components processing.
Background technology
In mechanical part processing, many parts need to be processed external diameter end face taking endoporus as benchmark, and the machining to this type of taking endoporus as benchmark is often aided with and completes processing as align member with mandrel.In the prior art, mandrel only has the function of location conventionally, does not possess the effect that clamps part to be processed; Moreover the mandrel of prior art, when for machining, and coordinates the problem that easily causes error because of gap between endoporus.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the invention provides the combined core-axle device in a kind of machine components processing, effectively solve the problem that above-mentioned prior art exists.
To achieve these goals, the technical solution used in the present invention is: the combined core-axle device in a kind of machine components processing, comprise mandrel and axle sleeve, one end of described mandrel is provided with a ring flange, and ring flange is provided with stopper slot, and mandrel is provided with three diameter segment, three diameter segment different in size, their length arrangement is that three diameter segment of mandrel are the structure that removably connects near ring flange end to the other end progressively from long to short, and described axle sleeve comprises two inner cone axle sleeves and an outer cone axle sleeve; Described inner cone axle sleeve is the cylindrical shape that center is through hole, and the bore area of its one end is taper seat, is provided with opening along circumference; Described cylindrical tapered sleeve is the only hollow cylinder shape of an end opening, and the outer surface of openend is taper seat, and the end face of the other end is provided with a conical centre bore, and described conical centre bore is along hole along being provided with antifriction pad.
As preferably: three diameter segment of described mandrel are the structure being socketed between two, fix by gim peg.
Compared with prior art, this beneficial effect of the invention: the present invention is simple in structure, makes the present invention have the function that clamps part to be processed to structural improvement, has reduced mismachining tolerance, the stopper slot arranging on ring flange, makes the present invention's stability in the time of running better.
Brief description of the drawings
Fig. 1 structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Referring to Fig. 1, combined core-axle 2 in a kind of machine components processing installs, comprise mandrel 2 and axle sleeve, one end of described mandrel 2 is provided with a ring flange, ring flange is provided with stopper slot 7, mandrel 2 is provided with three diameter segment, three diameter segment different in size, their length arrangement is near ring flange end to the other end progressively from long to short, 2 three diameter segment of mandrel are the structure that removably connects, in the present embodiment, three diameter segment of described mandrel 2 are the structure being socketed between two, fix by gim peg, described axle sleeve comprises two inner cone axle sleeves 3 and an outer cone axle sleeve 5, described inner cone axle sleeve 3 is the cylindrical shape that center is through hole, and the bore area of its one end is taper seat, is provided with opening along circumference, described cylindrical tapered sleeve is the only hollow cylinder shape of an end opening, and the outer surface of openend is taper seat, and the end face of the other end is provided with a conical centre bore, and described conical centre bore is along hole along being provided with antifriction pad.
The present invention in use, the ring flange that mandrel 2 arranges is connected with the flange disk 1 on lathe, processed part 4 is arranged on the corresponding axial location of two inner cone axle sleeves 3, and serious 6 on lathe withstands in the conical centre bore of outer cone axle sleeve 5, and antifriction pad plays the function of the degree of reducing wear.
