Abstract
The present invention relates to a drill clamping chuck universally used for conic workpieces and cylindrical workpieces, which comprises an outer shell provided with a conical inner chamber, a T-shaped flange and a drilling clamping chuck handle. The present invention is characterized in that clamping jaws are hinged on a push block through a shaft pin, and a top tip is arranged in the core hole of the drill clamping chuck. When the present invention is used for clamping cylindrical workpieces, such as a cylinder, the clamping jaws tightly cling to the push block and serve as rigid clamping jaws. When the present invention is used for clamping conical workpieces, the workpieces are centered and clamped tightly by the matching of the clamping jaws and the top tip. With the structure, the present invention has the characteristics of simple structure, high work efficiency, etc.
Description
The present invention relates to that a kind of awl is straight-through uses drill chuck, the equipment such as drilling machine, lathe, milling machine, boring machine that are applicable to are made universal fixturing.
Drill chuck that prior art relates to such as scroll chuck, common drill point are first-class, its operation principle is for being provided with the rigid jaw more than three or three at scroll chuck or the first-class radian of common drill chuck, the rigid jaw radial motion, clamping work pieces also makes workpiece centering location.The prior art constructions feature make jaw be clamping element be again setting element, its action links, and can constant speed becomes into or recesses workpiece, makes the symmetrical centre axis of workpiece not produce displacement, thereby realizes that centering clamps.It is straight cylinder that but prior art is only applicable to workpiece, as cylinder etc.For the cone workpiece, prior art can't realize directly that then the centering location clamps, and must could be clamped by centering by the cooperation of the tapered sleeve that conforms to the workpiece tapering.
Purpose of the present invention will provide a kind of awl to lead directly to exactly and use drill chuck, to overcome the deficiency of prior art.
The object of the present invention is achieved like this: a kind of awl is straight-through uses drill chuck, includes the shell body of conical internal cavity, and T shape flange and drill chuck handle is characterized in that jaw is articulated on the pushing block by pivot pin, are provided with top in drill chuck core hole.
Described a kind of awl is straight-through uses drill chuck, it is characterized in that on the drill chuck handle screw thread being arranged, and on the drill chuck handle adjustable ring is set, have in the adjustable ring with the drill chuck handle on the screw thread of threads engaged, and annular groove is arranged; Be provided with pin at top afterbody, the pin tail places in the annular groove.
Design concept of the present invention is the rotatable jaw of the fixed supported rigid jaw of available technology adopting being changed into the self-alignment supporting or claiming floating support.The variation of reference position and adjusting automatically can be located along with workpiece in the position of floating support point, make with it to adapt to; Depress wherein that all the other promptly rise, till whole contacts, its effect still is equivalent to a fixed bearing, only limits one degree of freedom.The present invention is when clamping cylindricality workpiece such as cylinder, and jaw is close on the pushing block, and the effect of being played is equivalent to the effect that rigid jaw played in the prior art.As the present invention during at clamping cone workpiece, thereby the automatic turn of jaw makes the jaw face be close to taper work surface clamping work pieces, is arranged at top in the drill chuck core hole and heads in the centre bore of taper work, makes workpiece centering under the cooperation of jaw.Can regulate the length that is held that top position in drill chuck core hole can change workpiece by adjustable ring.It is simple in structure that said structure of the present invention has it, characteristics such as operating efficiency height.
Below by embodiment, in conjunction with the accompanying drawings the present invention is further described.
Fig. 1 is the structural representation of an embodiment of the present invention.
Among the figure (1) be shell body, (2) for conical internal cavity, (3) for jaw, (4) for pivot pin, (5) for pushing block, (6) for T shape flange, (7) for bearing, (8) for top, (9) for interior be equipped with female, (10) be annular groove for pin, (12) for drill chuck handle, (13) for adjustable ring, (11).Among the embodiment, jaw (3) is articulated on the pushing block (5) by pivot pin (4), is provided with in drill chuck core hole top (8).On drill chuck handle (12), screw thread is arranged, adjustable ring (10) is set on drill chuck handle (12), the screw thread of going up threads engaged with drill chuck handle (12) is arranged in the adjustable ring (10), and annular groove (13) is arranged; Afterbody is provided with pin (11) in top (8), and pin (11) tail places in the annular groove (13).T shape flange (6) periphery has screw thread, and and drill chuck handle (12) chamber screw-internal thread fit, pushing block (5) is in relation to T shape flange (6).When rotational shell body (1), under the effect of screw thread, T shape flange (6) moves and drives pushing block (5) along axis and moves along axis.Pushing block (5) is realized moving radially under the constraint of conical internal cavity (2), thereby realizes unclamping or clamping work pieces.Present embodiment is when clamping cylindricality workpiece such as cylinder, and jaw (3) is close on the pushing block (4), and the effect of being played is equivalent to the effect that rigid jaw played in the prior art.As the present invention during at clamping cone workpiece, jaw (3) thus turn makes the jaw face be close to taper work surface clamping work pieces automatically, top (8) that are arranged at head in the centre bore of taper work in drill chuck core the hole in, and workpiece is felt relieved.Can regulate the length that is held that top (8) position in drill chuck core hole can change workpiece by adjustable ring (10).
Claims (2)
1, a kind of awl is straight-through uses drill chuck, includes the shell body of conical internal cavity, and T shape flange and drill chuck handle is characterized in that jaw is articulated on the pushing block by pivot pin, are provided with top in drill chuck core hole.
2, awl as claimed in claim 1 is straight-through uses drill chuck, it is characterized in that on the drill chuck handle screw thread being arranged, and on the drill chuck handle adjustable ring is set, have in the adjustable ring with the drill chuck handle on the screw thread of threads engaged, and annular groove is arranged; Be provided with pin at top afterbody, the pin tail places in the annular groove.
