Abstract
The invention discloses a floating axial support attached to a chuck gripping jaw. The floating axial support comprises a pull handle, a slide bar, a pipe body, a spring and a chuck gripping jaw, wherein the pipe body is obliquely and fixedly connected to the side face of the chuck gripping jaw; the slide bar in which the spring is sleeved is arranged in the pipe body; the slide bar exposed out of the upper end of the pipe body is connected with the pull handle, so that a manual elastic mechanism is constructed; the slide bar has a stepped shaft structure; the large-diameter section of the slide bar is positioned at the bottom, is in clearance fit with the inner hole of the pipe body, and is provided with an inclined surface boss which moves in a longitudinal open groove in the outer wall of the pipe body in a limited way; the oblique angle of the inclined surface boss on the slide bar and the oblique angle of the pipe body are in the same direction, and are equal to each other; and the inclined surface boss of the large-diameter section of the slide bar is pressed against the inner end face of a workpiece, so that an axial floating support is constructed. The floating axial support is constructed on the end face of one side of the workpiece which is far away from an axle hole, so that the rigidity is enhanced remarkably, the production efficiency is increased, and the overall end face processing quality is improved. The floating axial support is simple in structure, is placed accurately and rapidly, is positioned reliably, and is particularly suitable to be taken as an auxiliary support for use in large-scale production.
Description
Technical field
The present invention relates to a kind of aiding support that is located in the machining fixture, specifically, the present invention relates to a kind of unsteady axially mounting that is attached on the chuck jaw.
Background technology
Eccentric cover is a kind of common machine components, and special because of its structure, the structural strength of each one of end face and rigidity difference are larger, and facing processing back plane degree and roughness difficulty reach designing requirement.The end cap of hand oil pump is a kind of typical Thin-Walled Eccentric lid, axis hole on the end cap is decided according to the rotor amount of bias, one side end face rigid phase away from axis hole is poor to one side end face in paraxial hole, under same cutting output condition, process, end face flatness and the roughness of end cap are relatively poor, its reason is one side end face poor rigidity away from axis hole, and end face produces strain during turning.Usually adopt the method that reduces cutting output to realize producing in the industry, this finish turning method can significantly reduce the end face elastic deformation amount, but still can not realize end face flatness problem up to standard.In addition, the smart cutting of trace production efficiency is low, can not satisfy requirements of mass production.
Summary of the invention
The present invention proposes a kind of unsteady axially mounting that is attached on the chuck jaw mainly for the deficiencies in the prior art, and this supporting structure is simple, and it is accurate, quick to put in place, and the location is reliable.Unsteady axially mounting is positioned at eccentric cover to be processed away from one side inner face of axis hole, directly strengthens this rigidity, thereby reaches the purpose that improves the whole crudy of end face.
The present invention is achieved through the following technical solutions technical goal.
Be attached to the unsteady axially mounting on the chuck jaw, it comprises handle, slide bar, body, spring and chuck jaw.Described body is fixedly connected on a chuck jaw side, the slide bar of the built-in pocketed springs of body, and the slide bar and the handle that expose from the body upper end connect and compose Manual elastic mechanism.Its improvements are: the relative chuck jaw of the axis of described body outer face tilts to the inside, and its included angle is acute angle, and body hypomere tube wall outwardly leaves the longitudinal opening groove.Described slide bar is the multidiameter structure, enlarged diameter section is in bottom and body endoporus matched in clearance, the slide bar enlarged diameter section is provided with the inclined-plane boss along the spacing movement of the open slot of body, this angle of chamfer and body oblique angle in the same way and angle equate that slide bar inclined-plane boss with enlarged diameter section under spring action consists of the axially mounting that floats by real workpiece inner face.
In the said structure, the inside tilting acute angle in the relative chuck jaw of body axis outer face is α=6
0～10
0, spring is Compress Spring.
The present invention compared with prior art has following good effect:
1, unsteady axial bearing structure is simple, easily makes;
2, put down handle after the Workpiece clamping, slide bar under the effect of spring with the inclined-plane boss by real workpiece inner face, floating axle to supporting put in place accurately, quick, the location is reliably;
3, workpiece obtains the axially mounting that floats away from one side inner face of axis hole, significantly strengthens this rigidity, is conducive to enhance productivity and the whole crudy of end face.
Description of drawings
Fig. 1 is structural profile schematic diagram of the present invention.
Fig. 2 is that partial structurtes of the present invention are cutd open schematic diagram.
The specific embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Be attached to the unsteady axially mounting on the chuck jaw shown in the accompanying drawing, it comprises handle 1, slide bar 2, body 3, spring 4 and chuck jaw 5.Described body 3 is fixedly connected on wherein chuck jaw 5 sides of scroll chuck, the slide bar 2 of body 3 built-in pocketed springs 4, and the slide bar 2 that exposes from body 3 upper ends connects and composes Manual elastic mechanism with handle 1.The present invention has adopted tilting resilient movement structure in order to reach random position holding workpieces 6 away from the purpose of axis hole one side inner face.The relative chuck jaw of the axis of present embodiment middle tube body 35 outer faces slope inwardly 7
0, after floating axle under this angle condition is real to a breasting, having certain self-locking performance, the axially mounting of guaranteeing to float is reliable.Body 3 hypomeres tube wall outwardly leaves longitudinal opening groove 3.1, slide bar 2 is the multidiameter structure, enlarged diameter section is in bottom and body 3 endoporus matched in clearance, slide bar 2 enlarged diameter sections are provided with inclined-plane boss 2.1 along the open slot 3.1 spacing movements of body 3, this angle of chamfer and body 3 oblique angles in the same way and angle equate.When workpiece 6 is seated in the chuck jaw 5, to place the elastic mechanism place away from one side end face of axis hole, the operative employee pulls out handle 1, making to move on the inclined-plane boss 2.1 on the slide bar 2 does not affect workpiece 6 and lays, when leaning on to chuck jaw 5 outer face, the inner face of workpiece 6 implements to clamp, then loosen handle 1, slide bar 2 consists of the axially mounting that floats with the inclined-plane boss 2.1 of enlarged diameter section by real workpiece 6 inner faces under Compress Spring 4 effect.Because workpiece 6 obtains the axially mounting that floats away from one side end face of axis hole, this rigidity is significantly strengthened, and is conducive to enhance productivity and the whole crudy of end face.
