Abstract
The invention discloses a spring chuck capable of automatically discharging. An ejector rod is fixed in a hollow chuck body, a compression spring is arranged on the ejector rod, and the ejector rod can always keep in an ejecting and extending state through the compression spring. When a pipe fitting is clamped, the ejector rod moves backwards through the extrusion of the pipe fitting, the compression spring fixed on the ejector rod is further compressed, and meanwhile the pipe fitting is fixed through the clamping force of the spring chuck. After the pipe fitting is machined, the spring chuck is loosened through a mechanism, at the time, the clamping force, clamping the pipe fitting, from the spring chuck is not exerted on the pipe fitting, and the ejector rod moves forwards through the compression spring, meanwhile, an ejector claw on the ejector rod ejects and supports the pipe fitting to eject the pipe fitting out of the spring chuck, and the automatic discharging operation is finished. The situation that the working efficiency is low in a traditional manner of manual material taking is changed, and machining efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of machined components, be specifically related to a kind of collet that can automatically discharge the pipe fitting of clamping.
Background technology
Collet is a kind of conventional clamping tool for machine work, and it has simple in structure, and reliability is high, is convenient to the advantages such as replacing, is mainly used in fixing shaft object.The clamping section of collet is generally divided into many lobes, and the lateral surface of clamping section is general also for the outside of ，Qi clamping section, inclined-plane also has a gripping sleeve coordinating with it, and the inner surface of gripping sleeve is also inclined-plane.Effect by gripping sleeve makes the various piece of clamping section draw close to center, thereby realizes the clamping to object that wrap up its inside.But object, after completing processing, due to the existence of gripping sleeve, is adding that whole collet is arranged on mount pad, therefore, be difficult to directly object be taken out, particularly clamp pipe fitting, be more difficult to take out, greatly affected the efficiency of processing.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of collet of automatic discharge, can after pipe fitting completes processing, automatically pipe fitting be deviate to collet, reduces manually to take out the time of pipe fitting, and working (machining) efficiency is provided.
For achieving the above object, technical scheme of the present invention is: the collet of automatic discharge, comprise chuck body, described chuck body is divided into the clamp segment of front end and the canned paragraph of rear end, described clamp segment is taper, described clamp segment is divided into three lobes by three notches, form the chuck of clamping pipe fitting, described canned paragraph hollow, in the cavity of described canned paragraph and clamp segment, the cavity of clamping pipe fitting is communicated with, in the cavity of canned paragraph, be provided with a push rod, the front end of described push rod stretches in the cavity of clamping pipe fitting in clamp segment, described push rod front end is provided with three top pawls that insert in notch, the thickness of described top pawl is less than the width of clamp segment notch when clamped condition, the rear end of described canned paragraph is fixed with a push rod support set, has a circle annular protrusion on described push rod, is provided with a Compress Spring on described push rod between annular protrusion and push rod support set.
While adopting technique scheme, owing to having fixed a push rod in the chuck body in hollow, and on push rod, be provided with a Compress Spring, the state that this Compress Spring can keep push rod to stretch in top constantly.When clamping pipe fitting, push rod moves backward under the extruding of pipe fitting, further compresses Compress Spring fixed thereon, and pipe fitting relies on the chucking power of collet to maintain static simultaneously.Treating that pipe fitting completes adds ，You mechanism trip spring chuck in man-hour, and now, pipe fitting loses the chucking power of collet, and push rod moves forward under the effect of Compress Spring, and the top pawl jacking pipe fitting on it, by pipe fitting ejector spring chuck, completes the operation of automatic discharge simultaneously.Changed the lower situation of the artificial feeding operating efficiency of traditional use, the working (machining) efficiency greatly improving.
Further, in order to regulate push rod to stretch into the length in collet, described push rod support set is fixed on by rotation stopping screw on the canned paragraph of chuck body, and the rear end of described push rod support set is also provided with a push rod adjusting nut, and described push rod adjusting nut and push rod are connected and fixed.Because push rod support set is fixed on the canned paragraph of chuck body by rotation stopping screw, while therefore rotating push rod adjusting nut, it can not rotate thereupon, can along with the rotation of push rod adjusting nut, regulate push rod to stretch into the length in collet, to adapt to the processing needs of different length pipe fitting.
Further, in order to reduce the frictional force between top pawl and collet, it is ejected pipe fitting fast, the front end of described top pawl is taper.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the collet embodiment of band automatic discharging device of the present invention.
The specific embodiment
As shown in Figure 1, the collet of band automatic discharging device of the present invention, comprises chuck body, and chuck body is divided into the clamp segment 1 of front end and the canned paragraph 2 of rear end, and this clamp segment 1 is taper, and clamp segment 1 is divided at least three lobes, forms the chuck of clamping pipe fitting 7.Canned paragraph 2 is hollow structure, the cavity of the cavity of canned paragraph 2 and the interior clamping pipe fitting 7 of clamp segment 1 is communicated with, in the cavity of canned paragraph 2, be provided with a push rod 3, the front end of push rod 3 stretches in the cavity of the interior clamping pipe fitting 7 of clamp segment 1, described push rod 3 front ends are provided with three top pawls 31 that insert in notch, and the thickness of described top pawl 31 is less than the width of clamp segment 1 notch when clamped condition.In the rear end of canned paragraph 2, be fixed with a push rod support set 4, on described push rod 3, have a circle annular protrusion, on described push rod 3, between annular protrusion and push rod support set 4, be provided with a Compress Spring 5.This push rod support set 4 is fixed on by rotation stopping screw 41 on the canned paragraph 2 of chuck body, and the rear end of push rod support set 4 is also provided with a push rod adjusting nut 6, and this push rod adjusting nut 6 is fixed together with push rod 3.
Owing to having fixed a push rod 3 in the chuck body in hollow, and on push rod 3, be provided with a Compress Spring 5, the state that this Compress Spring 5 can keep push rod 3 to stretch in top constantly.When clamping pipe fitting 7, push rod 3 moves backward under the extruding of pipe fitting 7, further compresses Compress Spring 5 fixed thereon, and pipe fitting 7 relies on the chucking power of collet to maintain static simultaneously.Treating that pipe fitting 7 completes adds ，You mechanism trip spring chuck in man-hour, now, pipe fitting 7 loses the chucking power of collet, and push rod 3 moves forward under the effect of Compress Spring 5, simultaneously top pawl 31 jacking pipe fittings 7, by pipe fitting 7 ejector spring chucks, complete the operation of automatic discharge.Changed the lower situation of the artificial feeding operating efficiency of traditional use, the working (machining) efficiency greatly improving.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
