The utility model discloses simple structure, it is tight to make the automatic shrink when the clamping of the irregular work piece of appearance press from both sides, convenient operation has improved handling efficiency, and the work piece is more stable during the machine tooling, has guaranteed properties of product, great improvement the quality that the clamping locating clip is tight and the efficiency of product.
Description
Technical field
The utility model relates to a kind of collet, particularly a kind of special-shaped collet for the irregular workpiece of clamping profile.
Background technology
For the irregular workpiece of profile, due to its Set and Positioning face out-of-shape, common clamping tool is difficult to find suitable location clamping point at its external surface as plain cylindrical form workpiece, possibly by a series of centering, clamping, is then arranged on lathe, centering clamping again, process is loaded down with trivial details, reduces the production efficiency of product, brings inconvenience to work; And after clamping workpiece, when frock is arranged on lathe, because of the problem that locating surface irregular generation clamping force is uneven, also reduce crudy.
Utility model content
The technical problems to be solved in the utility model is that the efficiency of loading and unloading is low in order to overcome prior art complicated operation, adds the defect of workpiece stability difference in man-hour, provides a kind of special-shaped collet for the irregular workpiece of clamping profile.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of special-shaped collet, it comprises interconnective tapering clamping section and cylinder clamping section; Described tapering clamping section is provided with some retraction slots, and described tapering clamping section comprises a cone and cylinder, and the inner side of described cone is a concave surface.This concave surface is identical with clamping workpiece locating surface profile, ensures that the positioning supports of workpiece in frock is good, and Workpiece clamping stress point can be made more even during clamping, makes workpiece clamp more stable man-hour adding.
Preferably, the outside of described cone is a conical surface, and the stress arranged when cone structure can ensure clamping is excessive gently, improves the stability of frock.
Preferably, described cone is provided with some rectangles or circular groove.In tapering clamping section open rectangle and circular groove object be in order to after making clamping workpiece, frock is arranged on can by overall shrinkage and then clamping work pieces on lathe, the object of circular groove is to reduce contraction dynamics, and make contraction more easy, workpiece is more easily clamped.
Preferably, described cylinder clamping section is positioned at the outside of described cylinder, and the inner side of described cylinder is provided with a cylindrical hole.Through hole act as loss of weight, and retraction slot can be made more easily to shrink when stressed.
Preferably, described retraction slot is wide, and described retraction slot is uniformly distributed in described tapering clamping section.When these retraction slots make frock be arranged on lathe, can clamp external cylindrical surface by chuck makes notch shrink, frock concave surface is driven to shrink to work piece interface, Workpiece fixing is clamped carry out simultaneously, and ensure the uniform force of each contact point of all directions, make stressed effect in the machined of workpiece better, improve crudy.
Preferably, described special-shaped collet is made up of spring steel, and described spring steel is technical term known in those skilled in the art, and the intensity of spring steel is high, and resistance to impact is good, good stability.
Positive progressive effect of the present utility model is: the utility model structure is simple, the irregular workpiece of profile is made automatically to shrink clamping when clamping, easy to operate, improve the efficiency of loading and unloading, and workpiece is more stable during machined, ensure that properties of product, improve quality and the efficiency of the Set and Positioning clamping of product greatly.

Detailed description of the invention
Mode below by a preferred embodiment further illustrates the utility model, but is not therefore limited among described scope of embodiments by the utility model.
As shown in Figure 1-2, a kind of special-shaped collet, it comprises interconnective tapering clamping section 1 and cylinder clamping section 2; Described tapering clamping section 1 is provided with some retraction slots 3, and described tapering clamping section 1 comprises a cone and cylinder, and the inner side of described cone is a concave surface 4.The outside of described cone is a conical surface.Described cone is provided with some rectangles or circular groove 5.Described cylinder clamping section 2 is positioned at the outside of described cylinder, is provided with a cylindrical hole 6 inside described cylinder.Described retraction slot 3 is wide, and described retraction slot 3 is uniformly distributed in described tapering clamping section 1.
As shown in Figure 3, cylinder clamping section 2 is determined with using the chuck of lathe according to clamping workpiece profile size, tapering clamping section 1 is determined jointly according to workpiece configurations size and cylinder clamping section 2, wherein the tapering of tapering clamping section 1 can suitably regulate, principle is: excessive gently, ensure chuck strength, alleviate fixture overall weight, and ensure to wrap workpiece configurations locating surface completely.
As shown in Figure 4, comprise the wide retraction slot of decile 3, middle cylindrical hole 6, for the concave surface 4 of clamping workpiece, this concave surface is identical with clamping workpiece face shape, wherein the groove width of retraction slot 3 and groove depth are determined according to the diameter of the length of cylinder clamping section 2 and tapering clamping section 1, wherein the diameter of cylindrical hole 6 is determined according to the external diameter of cylinder clamping section 2, principle is: ensure that certain wall thickness guarantees frock intensity, suitable increasing reduces the pretightning force of clamping work pieces, increases the weight alleviating frock as much as possible; Wherein the degree of depth determination principle of concave surface 4 is: guarantee that tool positioning surface wraps up completely, ensures chuck strength, makes the overall weight of frock reduce to greatest extent.This concave surface can be used for profile regular workpiece clamping equally, as: when workpiece configurations is bar, its locating surface is one section of face of cylinder, and now, this frock concave surface changes one section of face of cylinder into.
The utility model abnormity collet clamping process is: the locating surface of workpiece is embedded in concave surface 4, cylinder clamping section 2 loads machine chuck, and chuck tightens up, and drives retraction slot 3 to shrink, concave surface 4 contacts with Workpiece fixing face and compresses until workpiece is clamped completely, completes clamping workpiece.
Described in this preferred embodiment, special-shaped collet is made up of spring steel.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", " top ", " end ", etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
