Abstract
The utility model discloses a kind of floating mechanism of expandable, it is characterized in that: comprise sleeve, floating parts and swivel nut, described sleeve is threaded with described swivel nut, described floating parts and described sleeve are socketed, the length of described sleeve is greater than the length of described swivel nut, the part that described sleeve stretches out described swivel nut is provided with opening, and described floating parts are resisted against described opening part.The technical program can realize the polishing to parts inner surface in small space, and accuracy is high, and requisite space is little.
Description
Technical field
The utility model relates to field of machining, especially relates to the floating mechanism of a kind of expandable of floating operation in small space.
Background technology
In the process of fine turning lathe polishing, polishing in the surface for tiny parts, often has very high technical requirement.Can meet the basic demand of people in prior art for the technique for grinding of outer surface, but for the polishing of inner surface, often can not enter people's will.The direct contact surface that the inner surface of parts normally connects between parts, the performance for parts has a great impact, if the technique for grinding of inner surface is bad, serious wear can be caused even directly to damage.In prior art, the polishing for inner surface is by the automatically grinding under lathe or digital automation control equally, is ensureing, under the prerequisite that control accuracy is high, to need the technical capability that operating personnel are very high equally.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is the floating mechanism proposing a kind of expandable.
The purpose of this utility model will be achieved by the following technical programs: a kind of floating mechanism of expandable, comprise sleeve, floating parts and swivel nut, described sleeve is threaded with described swivel nut, described floating parts and described sleeve are socketed, the length of described sleeve is greater than the length of described swivel nut, the part that described sleeve stretches out described swivel nut is provided with opening, and described floating parts are resisted against described opening part.
Preferably, the floating mechanism of above-mentioned a kind of expandable: described floating parts and described sleeve are connected through the hinge.
Preferably, the floating mechanism of above-mentioned a kind of expandable: described floating parts comprise floating bar and floating, described floating can extend radially out and regain described sleeve.
Preferably, the floating mechanism of above-mentioned a kind of expandable: the junction between described floating and described floating bar is that circular arc bends.
Preferably, the floating mechanism of above-mentioned a kind of expandable: described floating bar is provided with handle, and described handle is rotatable.
Preferably, the floating mechanism of above-mentioned a kind of expandable: described floating is the veined plane of surperficial tool.
Outstanding effect of the present utility model is: 1) in narrow space, floating mechanism can radially stretch out and withdrawal, polish to the inner surface of parts, can meet the job requirements under small space, the component technological obtained can be higher relative to other technologies scheme; 2) floating face is resisted against opening part, when needing floating, just by floating release, can carry out the polishing of floating, after withdrawal, regain in opening part, can not take too much space for this floating; And floating stretch out with withdrawal displacement is little, can action timely.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of floating mechanism of expandable.
Detailed description of the invention
As shown in Figure 1, the floating mechanism of a kind of expandable of the present embodiment, comprise sleeve 1, floating parts 2 and swivel nut 3, sleeve 1 is threaded with swivel nut 3, that is, can mutually rotate between the two, and in the process of rotating, axial displacement can occur sleeve 1.Floating parts 2 comprise floating bar 21 and floating face 22, and the surface in floating face 22 has texture, can maximum efficiency reach floating object.Junction between floating face 22 and floating bar 21 is that circular arc bends.Floating face 22 can extend radially out and regain sleeve 1, and floating bar 21 is socketed with sleeve 1, and floating parts 2 are connected through the hinge with sleeve 1, and floating face 22 can be driven when sleeve 1 action to stretch out and withdrawal sleeve 1.The length of sleeve 1 is greater than the length of swivel nut 3, and the part that sleeve 1 stretches out swivel nut 3 is provided with opening 4, and floating parts 2 are resisted against opening 4 place.
Optionally, floating bar 21 is provided with handle 5, and handle 5 is rotatable, and handle 5 can move axially along sleeve 1, thus drives floating face 22 to stretch out and withdrawal, does floating technique to the inner surface of parts.
When rotating swivel nut 3, driving the sleeve 1 be threaded with it to rotate, thus changing the distance of radial direction into axial distance, promote sleeve 1 and produce displacement.Due to sleeve 1 and floating parts 2 chain connection, thus drive floating face 22 to stretch out opening 4, carry out floating to the narrow and small inner surface space of parts.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
