Abstract
The utility model provides a three-claw self-centering adjustable chuck, which comprises a chuck body, a clamping pawl and a chuck wire, wherein the clamping claw is formed by the connection of a claw seat matched with the chunk wire and the chuck body, and a claw body of a holding work piece, and the utility model is also provided with a position adjusting structure of the claw body correspondingly to the claw seat in the radial direction of the chuck body. The utility model divides the clamping claw into a matching part of the chuck wire and the chuck body and a holding work par, in the locking and loosening operation, the two parts can be linked and can also be singly acted, once the condition that the centering is not accurate occurs, the centering adjustment operation is conveniently performed by the position adjusting structure, and thus errors caused by inaccurate centering of the chuck in the process of clamping and centering are effectively avoided.
Description
Technical field
The utility model relates to a kind of chuck, is meant the three-jaw self-centering chuck of using on the lathe especially.
Background technology
In the prior art, all be to pull wheel by rotation to drive parcel and jaw is tightened up and unclamp in the three-jaw self-centering chuck, clamp and the purpose of unclamping workpiece thereby reach.The shortcoming of this three-jaw self-centering chuck is: chuck when feeling relieved inaccurate and causing error to regulate, makes the workpiece circular runout very big in the middle of the Centering Clamping process.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of three jaw self-centering adjustable chucks that overcome above-mentioned defective.For this reason, the present invention by the following technical solutions: it comprises disk body, claw, parcel, and described claw is formed by connecting by the pawl seat that cooperates with parcel and disk body and the corpus unguis of holding workpiece, and it also is provided with corpus unguis and directly makes progress with respect to the position adjustment structure of pawl seat at disk body.Owing to adopt technique scheme, the utility model is the part that cooperates with parcel and disk body and the part of holding workpiece with the claw split, when locking and unclamp operation, but these two parts are also single action of linkage both, in case run into the inaccurate situation of centering, can be by the position adjustment structure adjusting of feeling relieved easily, thus effectively avoided chuck in the Centering Clamping process, the inaccurate and error that causes of centering.
Above-mentioned position adjustment structure can adopt multiple mode, such as, described corpus unguis is provided with the connector of threaded endoporus, and the pawl seat is provided with the screw rod that directly upwards is positioned at disk body that cooperates with threaded interior hole.Adopt this structure, easy to assembly, and directly upwards the location is reliable each other at disk body for pawl seat and corpus unguis.
Pawl seat and corpus unguis can be provided with at disk body and directly upwards be slidingly matched, disk body axially on the location guide rail and the slider guide that cooperate.Like this, this slide construction also has the pawl of maintenance seat and the effect that corpus unguis axially is connected, and makes syndeton simple more compact.

The specific embodiment
With reference to accompanying drawing.The utility model comprises disk body 1, claw 2, parcel, and described claw is formed by connecting by the corpus unguis 4 of pawl seat 3 that cooperates with parcel and disk body and holding workpiece, and it also is provided with corpus unguis and directly makes progress with respect to the position adjustment structure of pawl seat at disk body.
Described corpus unguis is provided with the connector 6 of the threaded endoporus 11 in lower end, and the upper end of pawl seat is provided with the screw rod 9 that directly upwards is positioned at disk body that cooperates with threaded interior hole.Described connector 6 is the cylinder that is connected with corpus unguis.Drawing reference numeral 10 be with cylinder 6 close-fitting corpus unguis on the hole.
Shown in Fig. 3,4,6, guide rail 71 and slider guide 72 that pawl seat and corpus unguis are provided with at disk body and directly upwards are slidingly matched, the location cooperates on disk body is axial.Make pawl seat and corpus unguis be connected the location at disk body on axially, radially dewclaw seat and corpus unguis can slide relatively by regulating at disk body.
The upper end of pawl seat is provided with the positioning boss 14 that screw rod directly makes progress at disk body, and screw rod is provided with the detent 15 that matches.
The pawl seat directly upwards is provided with the step surface 16,17 that matches with corpus unguis at disk body, like this, and the position components in the transmission of power and when assembling when being more conducive to clamp operation.
Claims (6)
