Abstract

The utility model discloses an automatic positioning discharge device for a spring collet, which comprises a tapped-stem bolt, a stopping block, a spring collet, a compression spring and an ejector rod for discharge, wherein the tapped-stem bolt comprises a tapered stem part and a threaded part; the stopping block has a tapered hole and a threaded hole, which are matched with the tapered stem part and threaded part of the tapered-stem bolt respectively; a notch is formed in a solid body between the tapered hole in the stopping block and the outer wall of the stopping block; the spring collet comprises a root part and a claw part, and a cylindrical through hole is formed in the spring collet; and the spring collet is sleeved on the stopping block, the compression spring and the ejector rod; the stopping block is fixed on the root part of the spring collet by the tapered-stem bolt; the compression spring is positioned between the stopping block and the ejector rod; and the ejector rod is positioned on the claw part of the spring collet. The automatic positioning discharge device for the spring collet, which is adopted by the utility model, has a simple structure, convenience for regulation and high generality, and the stopping block has high locking force and operates reliably. The automatic positioning discharge device for the spring collet is suitable for batch production, thereby increasing production efficiency.

Description

A kind of collet is with locating discharge device automatically
Technical field
The utility model relates to a kind of automatic location discharge device, relates in particular to a kind of collet with locating discharge device automatically.
Background technology
At present, in machining, use collet that part is added man-hour, the position block in the collet be inconvenient to adjust, and part is after machining, and part can not taking-up fast from collet, to such an extent as to influence production efficient.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of collet that can conveniently adjust the interior position block of collet, also can discharge the part of clamping in the collet automatically with locating discharge device automatically.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of collet is with locating discharge device automatically; Comprise taper shank screw, stop body, collet, compression spring and be used for the push rod of discharge; Said taper shank screw comprises taper shank portion and threaded portion; Said stop body is provided with respectively suitable taper hole and the screwed hole of taper shank portion and threaded portion with the taper shank screw, on the taper hole of stop body and the entity between its outer wall, has cut notch; Said collet comprises root and claw, and its inside is cylindrical hole; Said collet is sleeved on stop body, compression spring and the push rod, and said stop body is fixed on the root of collet through the taper shank screw, and the compression spring is between stop body and push rod, and push rod is positioned at the claw of collet; Said push rod diameter is slightly thinner than the clamping diameter of collet.
During use, stop body is moved to desired location, tighten the taper shank screw, make the taper hole spreading, when the outer surface of stop body and collet root inner surface are tightly fitted, promptly realized the locking of stop body; With the claw that is held part insertion collet, and withstand push rod, realize location part to be processed to compress the compression spring; Make collet clamp part to be processed through external force, just can process part to be processed; After the completion to be processed, unclamp externally applied forces and make collet unclamp part to be processed, in the moment of unclamping, because the active force of compression spring has been realized the purpose that push rod is discharged part to be processed.
The claw of said collet comprises more than one claw, and the outside of said push rod is provided with the projection that equates with the claw number, and the slit that forms between the position of said projection and the claw is corresponding; The slit that the thickness of said projection has dwindled when being in clamped condition than collet is also narrow; When being discharged from part when being the thin-walled tubulose,, make this device also can operate as normal because the existence of projection has increased the roof pressure contact area of push rod head.
The claw number of said collet is three.
On the taper hole of stop body and the entity between its outer wall, three notches have been cut.
Beneficial effect: the collet that the utility model adopts is with location discharge device automatically, and is simple in structure, easy to adjust, versatility is good, and the stop body coupling mechanism force is strong, reliable operation, is particularly useful for producing in batches, to enhance productivity.

Structural representation when Fig. 1 does not clamp part for the utility model;
Structural representation when Fig. 2 clamps part for the utility model;
Fig. 3 is an A-A cross section structural representation among Fig. 2;
Fig. 4 is a B-B cross section structural representation among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be depicted as a kind of collet with locating discharge device automatically like accompanying drawing 1,2,3,4; Comprise taper shank screw 1, stop body 2, collet 3, compression spring 4 and be used for the push rod 5 of discharge; Said taper shank screw 1 comprises taper shank portion and threaded portion; Said stop body 2 is provided with respectively suitable taper hole and the screwed hole of taper shank portion and threaded portion with taper shank screw 1, on the taper hole of stop body 2 and the entity between its outer wall, has cut three notches; Said collet 3 comprises root and claw, and its inside is cylindrical hole; Said collet 3 is sleeved on stop body 2, compression spring 4 and the push rod 5, and said stop body 2 is fixed on the root of collet 3 through taper shank screw 1, and compression spring 4 is between stop body 2 and push rod 5, and push rod 5 is positioned at the claw of collet 3.
The claw of said collet 3 comprises three claws, and the outside of said push rod 5 is provided with three projections, and the slit that forms between the position of said projection and the claw is corresponding.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
