Abstract
The utility model discloses the design proposal of a jaw of a multi-jaw chuck of a lathe. The utility model is characterized in that the jaw is divided into a jaw body and a jaw head which are fixed to each other by screws., the jaw head of the jaw can be changed according to the material of workpieces and the processing requirements; consequently, the adapting range is widened, the machining accuracy is guaranteed, the repair is convenient, and the waste caused by that the whole set of the chuck needs to be changed because the abrasion is reduced.
Description
The utility model relates to a kind of claw of lathe multijaw chuck.
No matter scroll chuck, chuck etc. in the existing lathe chuck, its claw moulding and material are fixed, consistent, just exist some inherent shortcomings thus.The one, some are needed the powerful workpiece processing that is installed, do not reach the dynamics of being installed; The 2nd, the workpiece that some fineness are had relatively high expectations is installed, and can damage surface of the work again, does not reach processing request; The 3rd, after long-term the use, all can produce the little horn mouth in big the inside, claw outside, it is not tight that workpiece is installed, or the cylindrical of piece-holder part and the cylindrical concentricity reduction after the processing, in case this situation occurs, be difficult to repair, can only change one group of chuck, cause processing cost to improve waste material.
The purpose of this utility model is the defective at above-mentioned prior art, a kind of design of pawl head of replaceable claw is proposed, thereby the working face material of claw holding workpiece part or moulding can be changed because of processing object and requirement, enlarge the scope of application of claw, increase the service life.
The purpose of this utility model can realize by following proposal, is about to claw and is divided into card body and pawl head two parts, makes it affixed each other with screw.The card body still keeps former claw assembly structure and shape, can realize the replacing of pawl head part according to workpiece material and processing request like this.
Claw is connected required assembly structure with chuck, the pawl head all possess with the card body and is connected after adapt, i.e. pawl head design has with the locating slot and the tooth that block the body unanimity.
The claw of the replaceable pawl head that employing the design provides, according to the processing object needs, can change the pawl head by trip bolt, as adopt common pawl head, soft pawl head (material is copper or other soft material), powerful pawl head (clamping face of pawl head is the flute profile piece) or other paralycus head that conveniently is installed and processes are to satisfy different clamping forces, workpiece surface finish or requirement easy to process.Because the pawl head can be changed, when pawl head wearing and tearing, only need change a pawl head or the pawl head is repaired, thereby reduce processing cost, cut the waste.
The utility model is described in further detail below in conjunction with accompanying drawing, can not be interpreted as it is qualification to design.
Fig. 1 is the structural representation of common pawl head.
Fig. 2 is the structural representation that pawl head and card body are connected to claw.
Claw is divided into card body 5 and pawl head 1 two parts, and design has staged screw 2 on the pawl head 1, to realize by screw and to block the affixed of body.The pawl head is provided with and blocks assembly structure identical and that adapt on one's body, as locating slot 3 and tooth 4.
According to workpiece needs and processing request, or convenient for the assembling claw, and pawl head shapes and attached assembly structure thereof can be different, as not being with tooth etc.
Claims (2)
1, the claw of the replaceable pawl head on a kind of lathe chuck is characterized in that long pawl is divided into card body and pawl head two parts, makes affixed each other with screw.
2,, it is characterized in that the assembly structure of pawl head and adapting of card body, if any locating slot and tooth by the described claw of claim 1.
