Abstract
The utility model relates to a floating axial support attached to a chuck clamping jaw. The floating axial support attached to the chuck clamping jaw comprises a handle, a slide bar, a tube body, a spring and a chuck clamping jaw. The tube body is inclined and is fixedly connected to the side of the chuck clamping jaw. The slide bar which is sleeved with a spring is arranged in the tube body. The slide bar which emerges from the upper end of the tube body and the handle are connected to form a manual elastic mechanism. The slide bar is of a stepped shaft structure, a large diameter section at the bottom is in clearance fit with a tube body inner hole. A slope boss which is arranged on the large diameter section of the slide bar limitedly moves along a longitudinal open slot on the outer wall of the tube body. The inclined angle of the slope boss on the slide bar and the inclined angle of the tube body are in the same direction and are equal. The slide bar is under the action of the spring, and the slope boss of the large diameter section of the slide bar solidly leans against an inner end face of a workpiece to form the axial floating support. Due to the fact that a side end face of the workpiece acquires the floating axial support, wherein the side end face of the workpiece is away from a shaft hole, the rigidity of the part is significantly strengthened, thus the production efficiency and the overall processing quality of the end face are improved. The floating axial support provided by the utility model has the advantages of simple structure, accurate positioning, rapidness and reliable positioning, and is especially suitable as an auxiliary support applied for mass production.
Description
Technical field
The utility model relates to a kind of aiding support that is located in the machining fixture, and specifically, the utility model 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 bigger, 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 away from the paraxial relatively hole of end face rigidity, one side of axis hole is poor, under same cutting output condition, processes, and the 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.
The utility model content
The utility model is primarily aimed at the deficiency of prior art, proposes a kind of unsteady axially mounting that is attached on the chuck jaw, 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 one side inner face of eccentric cover to be processed away from axis hole, directly strengthens this rigidity, thereby reaches the purpose that improves the whole crudy of end face.
The utility model is realized technical goal through following technical proposals.
Be attached to the unsteady axially mounting on the chuck jaw, it comprises handle, slide bar, body, spring and chuck jaw.Said 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 said body outer face tilts to the inside, and its included angle is an acute angle, and body hypomere tube wall outwardly leaves the longitudinal opening groove.Said 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 and moves along the open slot of body is spacing; 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 leans on real workpiece inner face to constitute the axially mounting that floats.
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 the compression spring.
The utility model compared with prior art has following good effect:
1, unsteady axial bearing structure is simple, is prone to make;
2, put down handle after workpiece clamps, slide bar leans on real workpiece inner face with the inclined-plane boss under the effect of spring, 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, helps enhancing productivity and the whole crudy of end face.
Description of drawings
Fig. 1 is the utility model structural profile sketch map.
Fig. 2 is that the utility model partial structurtes are cutd open sketch map.
The specific embodiment
According to accompanying drawing and combine embodiment, the utility model is described further below.
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.Said 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 utility model has adopted tilting resilient movement structure in order to reach the purpose of random position holding workpieces 6 away from 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 a breasting is real, having certain self-locking performance at floating axle under this angle condition, 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 of body 3 3.1 spacing moving, 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 outwards spurs handle 1, and making to move on the inclined-plane boss 2.1 on the slide bar 2 does not influence workpiece 6 and lay;, the inner face of workpiece 6 implements to clamp when leaning on to chuck jaw 5 outer faces; Loosen handle 1 then, slide bar 2 leans on real workpiece 6 inner faces to constitute unsteady axially mounting with the inclined-plane boss 2.1 of enlarged diameter section in the effect of compression spring 4 down.Because workpiece 6 obtains the axially mounting that floats away from one side end face of axis hole, this rigidity is significantly strengthened, and helps enhancing productivity and the whole crudy of end face.
