Description

Duplex bearing positioning fixture
Technical field
The present invention relates to machining fixture technical field, more particularly to a kind of duplex bearing positioning fixture.
Background technology
Disk cover parts refer generally to the parts such as ring flange, end cap, transparent cover, and this kind of part mainly plays support, axially position and close Envelope is acted on, and such part clamp typically uses following several structures, one:Positioning is using spring expanding sleeve or oil pressure centering swelling;Two: Slide fit heart axle is positioned or centering taper hole rear end face is compressed;Three:End surface supporting is using non-yielding prop pad or oil pressure balance supporting etc..With Upper structure has the following disadvantages:1st, the centering of taper hole expansion set is unstable, complicated using oil pressure structure;2nd, slide fit mode has gap not Energy precision centering, centering efficiency is low;3rd, end face non-yielding prop is jumped to part end and requires high and oil pressure balance complex structure and fault rate It is high.
The content of the invention
The technical problem to be solved in the present invention is to provide that a kind of simple structure, positioning precision are high, rigidity is good and can realize efficiently automatic The duplex bearing positioning fixture of change.
In order to solve the above-mentioned technical problem, the technical scheme is that a kind of duplex bearing positioning fixture, including clamp body, first Supporting oscillating bearing, the second supporting oscillating bearing, tapered sleeve, ball bearing, gland compresses oscillating bearing, and heart axle is described Tapered sleeve is arranged on clamp body by ball bearing, and described the first supporting oscillating bearing and the second supporting oscillating bearing is relative up and down Set, constitute supporting oscillating bearing outer ring, the large cylindrical of described clamp body is convex spherical, constitutes supporting oscillating bearing inner ring; Described gland is connected by compressing oscillating bearing with heart axle, and described mandrel is provided with as the convex of compression oscillating bearing inner ring Sphere, described gland and heart axle abutting end is concave spherical surface, and described compression oscillating bearing and the concave spherical surface part of gland are engaged, Collectively form compression oscillating bearing outer ring.
Supported using oscillating bearing using ball bearing tapered sleeve positioning, lower locating surface, gland and heart axle are connected by oscillating bearing knot Structure, is floated using upper top pull-down and compressed so as to realize zero clearance positioning the advantages of realizing big processing rigidity, high precision and repeat fixed Position precision is within 0.002.Lower positioning support face uses oscillating bearing, realizes end face balanced compensated.
Described ball bearing is provided with door near one end of gland.
Described tapered sleeve lower end is provided with back-moving spring.
Alignment pin is additionally provided with, for making tapered sleeve be positioned at clamp body.
Described clamp body is provided with broaching tool pawl away from spindle end.
Using above-mentioned technical proposal, taper hole and large end face need to be on vertical composite grinding centers when overcoming existing such part processing The defect for processing to ensure the positioning precision of subsequent handling so as to cause high cost, is positioned in the present invention using ball bearing tapered sleeve, Lower locating surface is balanced compensated using oscillating bearing, effectively reduce cost and simplify in clamp structure, and the present invention gland and Heart axle is connected by oscillating bearing structure, is floated using upper top pull-down and compressed the features such as so as to realize big processing rigidity, high precision, Whole clamping process can be participated in manually, high degree of automation.
Brief description of the drawings
Fig. 1 is the structural representation of duplex bearing positioning fixture of the present invention;
Reference:1- clamp bodies;The supporting oscillating bearings of 2- first, the supporting oscillating bearings of 3- second, 4- back-moving springs, 5- tapered sleeves, 6- alignment pins, 7- ball bearings, 8- doors, 9- glands, 10- compresses oscillating bearing, 11- heart axles, 12- broaching tool pawls.
Specific embodiment
Specific embodiment of the invention is described further below in conjunction with the accompanying drawings.Herein it should be noted that for these realities The explanation for applying mode is used to help understand the present invention, but does not constitute limitation of the invention.Additionally, this hair disclosed below As long as involved technical characteristic does not constitute conflict and can just be mutually combined each other in bright each implementation method.
A kind of duplex bearing positioning fixture, including clamp body 1, the first supporting oscillating bearing 2, the second supporting oscillating bearing 3, tapered sleeve 5, ball bearing 7, gland 9 compresses oscillating bearing 10, and heart axle 11, tapered sleeve 5 is arranged on clamp body 1 by ball bearing 7 On, the first supporting supporting oscillating bearing of oscillating bearing 2 and second is oppositely arranged about 3, constitutes supporting oscillating bearing outer ring, folder Specific 1 large cylindrical is processed into convex spherical, constitutes supporting oscillating bearing inner ring;Gland 9 is by compressing oscillating bearing 10 and the heart Axle 11 is connected, and the Surface Machining of heart axle 11 goes out convex spherical, used as the inner ring for compressing oscillating bearing, gland 9 and the abutting end of heart axle 11 It is concave spherical surface, the concave spherical surface part for compressing oscillating bearing 10 and gland 9 is engaged, collectively forms compression oscillating bearing outer ring.
Supported using oscillating bearing using ball bearing tapered sleeve positioning, lower locating surface in the present invention, gland and heart axle are connected by closing Nodal axisn bearing structure, is floated using upper top pull-down and compressed so as to realize that zero clearance positions the advantages of realizing big processing rigidity, high precision And repetitive positioning accuracy is within 0.002.Lower positioning support face uses oscillating bearing, realizes end face balanced compensated.
Ball bearing 7 is provided with door 8 near one end of gland 9, and the lower end of tapered sleeve 5 is provided with back-moving spring 4, accurately fixed for part Position, tapered sleeve 5 is positioned on clamp body 1 by alignment pin 6, additionally, the remote end of centrifugal shaft 11 of clamp body 1 is provided with broaching tool pawl 12.
Operation principle:Due to ball bearing zero clearance and almost zero position error the characteristics of and alignment pin 6 in the presence of make tapered sleeve 5 It is accurately positioned with clamp body 1, part is arranged on rear spindle 11 on tapered sleeve 5 and is automatically inserted into clamp body 1, is existed by gland 9 It is accurately positioned under back-moving spring 4 and taper effect, the second supporting oscillating bearing 3 (upper outer ring) and part during continuing to push Large end face reliable contacts.So that part becames one with fixture, clamping process can be not required to manually join the last drop-down heart axle of broaching tool pawl With more preferably realization automates clamping.
Embodiments of the present invention are explained in detail above in association with accompanying drawing, but the invention is not restricted to described implementation method. For a person skilled in the art, in the case where the principle of the invention and spirit is not departed from, these implementation methods are carried out many Plant change, modification, replace and modification, still fall within protection scope of the present invention.
