Abstract
The utility model provides a combined core shaft device for processing mechanical parts, which consists of a core shaft, two inner core shaft sleeves and an outer cone shaft sleeve. When the combined core shaft device works, a flange disk of the core shaft is connected with a flange disk on a machine tool. The two inner core shaft sleeves are arranged in the middle section of the core shaft oppositely. The outer cone shaft sleeve is arranged in the rightmost section of the core shaft. The processed part is arranged on the corresponding axial positions of the two inner core shaft sleeves. A pressure applied by an ejector pin on the machine tool makes one ends of the two inner cone shaft sleeves, which are provided with cone chamfer angles, expand outwards so as to compress the processed part so as to not only play a role of positioning the processed part, but also play a role of clamping the processed part. The combined core shaft device is used for processing the mechanical parts which take inner bores as the reference processing outer diameter or the end surface and the like and has the advantages of convenient clamping and high positioning accuracy.
Description
Technical field
The utility model relates to mechanical device, is specifically related to the combined core-axle device that uses in a kind of machine components processing.
Background technology
In mechanical part processing, it is benchmark processing external diameter or end face etc. that many parts need with the endoporus, is the machining of benchmark with the endoporus for this type of, often is aided with and uses mandrel to finish processing tasks as align member.Known mandrel has only positioning function, and can not play the effect that clamps part to be processed simultaneously; In addition, the fit clearance between known mandrel and the part to be processed endoporus with matching causes accumulated error easily.
The utility model content
The purpose of this utility model is to provide the combined core-axle device that uses in a kind of machine components processing, to overcome the deficiency of above-mentioned known mandrel.
The technical solution of the utility model is as follows:
The combined core-axle device that uses in a kind of machine components processing, form by mandrel and axle sleeve, it is characterized in that: described mandrel is similar to " flange shaft ", promptly Zhou a end is provided with a flange disk, described axle is provided with three different-diameter sections, dwindle successively to the other end from flange disk end, the axle the different-diameter section between with the taper seat transition and linkage; 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 the center is a through hole, and the bore area of one end thereof is a taper seat, and is provided with opening along circumference; Described outer cone axle sleeve is the only hollow cylinder shape of an end opening, and the outer surface of openend is a taper seat, and the end face of the other end is provided with a conical centre bore.
It is the machine components of benchmark processing external diameter or end face etc. that the utility model is used to process with the endoporus, convenient mounting and clamping, positioning accuracy height.
Description of drawings
Fig. 1 is the utility model user mode principle schematic;
Fig. 2 is the structural representation of the mandrel in the utility model;
Fig. 3 is the structural representation of the inner cone axle sleeve in the utility model;
Fig. 4 is the left view of Fig. 3;
Fig. 5 is the structural representation of the outer cone axle sleeve in the utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the combined core-axle device that uses in the utility model machine components processing is made up of mandrel 2, two inner cone axle sleeves 3 and an outer cone axle sleeve 5.
As shown in Figure 2, the design feature of the mandrel 2 in the utility model: the axle left end be a flange disk, with the flange disk join the axle three different-diameter sections are arranged, from left to right dwindle successively, the different-diameter section the axle between with the taper seat transition and linkage.
Shown in Fig. 3,4, the design feature of the inner cone axle sleeve 3 in the utility model: the left end inner surface is the taper chamfering, and is provided with equally distributed four openings along circumference.
As shown in Figure 5, the design feature of the outer cone axle sleeve 5 in the utility model: the left end outer surface is the taper chamfering, and the end face of the other end is provided with a conical centre bore.
Using method of the present utility model and principle are as follows:
As shown in Figure 1, the flange disk of mandrel 2 left ends is connected with flange disk 1 on the lathe; Two inner cone axle sleeve 3 mutual reversed arrangement (no taper chamfered end mutually near) are installed in the stage casing of mandrel 2, and the taper seat of first inner cone axle sleeve 3 of left end contacts with the taper seat of mandrel 2; Outer cone axle sleeve 5 is installed in the rightest section of mandrel 2, and the taper seat of outer cone axle sleeve 5 left ends contacts with the taper seat of second inner cone axle sleeve 3; Part to be processed 4 be installed in two inner cone axle sleeves, 3 corresponding axial locations on; Thimble 6 on the lathe withstands the centre bore on outer cone axle sleeve 5 right sides.When the thimble on the lathe 6 is exerted pressure left, because the taper seat of first inner cone axle sleeve 3 of left end contacts with the taper seat of mandrel 2, the taper seat of outer cone axle sleeve 5 left ends contacts with the taper seat of second inner cone axle sleeve 3, then this power outwards expands an end that has the taper chamfering of two inner cone axle sleeves 3, thereby compress part to be processed 4, so both played positioning action, played the clamping effect again, and do not had fit clearance between keeper and the locating hole part to be processed 4.
