Abstract
The invention discloses a chuck of a blanking machine, and the structure of the chuck consists of a spring chuck, a movable component, and a clamping sleeve; taper is arranged at the outer side of the left end of the spring chuck and is provided with an external locking sleeve which is installed on a main axle; a clamping sleeve carrier is arranged at the inner side of the spring chuck; one end of the clamping sleeve carrier extends out of the spring chuck; a plurality of rolling chutes are arranged on the clamping sleeve carrier; an elastic component and the movable component are movably arranged in the rolling chute; the clamping sleeve is arranged at the inner side of the movable component; by the arrangement of the movable component, axial play produced by the fraction force of the chuck can be transformed into the rolling force of a rolling component; that is, the clamping sleeve only receives compaction force transmitted by the rolling component; the compaction force clamps the workpiece, without producing the axial play, thus guaranteeing the consistency of the size of cutting workpiece.
Description
Technical field
The present invention relates to a kind of blanking machine, relate in particular to a kind of clamping head of blanking machine.
Background technology
At present, the collet in order to location, clamping work pieces that generally uses on the lathe is to use the external screw thread of pull bar to be connected tension with the rear end internal thread of collet, produces axial tension.Chuck is converted to the clamping force at vertical and chuck center with axial tension, thereby workpiece is clamped by the compression of the conical surface of machine tool chief axis front end.But adopt this structure, workpiece can make spring add with frictional force between collet and produce relative rotation or axial float between head and the workpiece, influence the machining accuracy of workpiece.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of novel structure is provided, can have effectively avoided part along with the clamping head of blanking machine of clamping head toward retraction.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of clamping head of blanking machine, comprise collet, movable-component, gripping sleeve, the arranged outside of the left end of described collet has tapering, tapering is provided with the outer locking cover, the outer locking cover is installed on the main shaft, described collet inboard is provided with the clamping block set, one end of described clamping block set stretches out collet, clamp block set and be provided with many rolling grooves, being arranged in the rolling groove of elastic parts and movable-component activity, the inboard of described movable-component is provided with gripping sleeve, by movable-component is set, can will produce the rolling power that axial float is converted into rolling assembly by chuck frictional force, that is to say, gripping sleeve only is subjected to the thrust that rolling assembly transmits, and workpiece is clamped, and can not produce axial float.Thereby guarantee the dimensional uniformity of cut workpiece.
In the technique scheme, described movable-component is a ball, is convenient to movable-component moving in the gripping sleeve outside.
In the technique scheme, described ball is provided with more than 2 pairs or 2 pairs.
In the technique scheme, described gripping sleeve is provided with the opposite elongated slot of direction.
In the technique scheme, described elongated slot is provided with more than 2 groups or 2 groups.
Beneficial effect: the present invention compared with prior art has following beneficial effect:
1) novel structure of the present invention, by movable-component is set, the harmful friction that produces on the chuck can be absorbed the rolling power that is converted into rolling assembly, that is to say, the gripping sleeve that is arranged in the movable-component only is subjected to the thrust that rolling assembly transmits, workpiece is clamped, and can not produce axial float.Thereby guarantee the dimensional uniformity of cut workpiece.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
See Fig. 1～Fig. 3, described clamping head of blanking machine mainly is made of collet 1, movable-component 5, gripping sleeve 4 etc.
The arranged outside of the left end of described collet 1 has tapering, and tapering is provided with outer locking cover 7, and outer locking cover 7 is installed on the main shaft 8, and described collet 1 inboard is provided with and clamps block set 2, and an end of described clamping block set 2 stretches out collet 1.
Described clamping block set 2 is provided with many rolling grooves, being arranged in the rolling groove of described elastic parts and movable-component 5 activities, and the inboard of described movable-component 5 is provided with gripping sleeve 4.
Preferably, describedly step up to overlap 4 and be provided with the opposite elongated slot of direction.
Described movable-component 5 can be objects such as cylinder, and in other words, described movable-component 5 can move in gripping sleeve 4 outsides and get final product, and not as limit, the present invention is set to ball, is convenient to movable-component 5 moving in gripping sleeve 4 outsides.
As preferably, described elastic parts is a spring, can simplify technology, the convenient installation.
Its operation principle of clamping head of blanking machine is, collet 1 is connected outward with pull bar by internal thread, pull bar moves backward and produces an axial pulling force, collet 1 is owing to be subjected to the locking of the tapering of outer locking cover 7, collet 1 inwardly shrinks, produced a power perpendicular to collet 1 center, ball is subjected to this vertical power, to clamp at the gripping sleeve 4 of inboard, simultaneously, the frictional force that ball produces when again collet 1 being shunk absorbs, and ball rolls thereupon backward, thereby has effectively avoided the axial float between the chuck in clamping work pieces.Guaranteed the uniformity of processing work size.
When collet 1 loosened, the power that is applied on the ball disappeared, and the elastic parts that ball is set at the rolling groove end pushes back initial position, prepares clamping next time.
Though the present invention is described by preferred embodiment, yet the present invention is not limited to embodiment as described herein, also comprises various changes and the variation done without departing from the present invention.
