Abstract
The utility model provides a novel holding chuck which comprises a chuck body, a wire coiling provided with a center inner hole, and a jack catch. The chuck body is provided with a center column, the wire coiling is sleeved outside the center column of the chuck body; the wall of the center inner hole of the wire coiling is provided with a sheet block which is wearable or can reduce friction with the center column of the chuck body, and/or the position of the center column of the chuck body matched with the wire coiling is provided with the sheet block or an annular block which is wearable or can reduce friction with the centre inner hole wall of the chuck body. The novel holding chuck can reduce the friction of the wire coiling and the chuck body matched with the wire coiling, ensure that the wire coiling keeps a concentricity with the chuck body, can keep the precision of the holding chuck for a longer time, and prolong the service life of the holding chuck.
Description
Technical field
The utility model relates to a kind of chuck.
Background technology
In the prior art, chuck comprises disk body, the claw of chuck, be provided with parcel in the disk body, the front end face of parcel is threaded with claw, described disk body has centered cylinder, and described parcel is enclosed within the disk body centered cylinder and also can rotates as axle outward, when clamping is operated, rotate by turning the tool drives parcel, make claw draw clamping work pieces in.Chuck needs very high precision, but after using for a long time, easily because of wearing and tearing influence its precision, influences the machining accuracy and the quality stability of workpiece.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of chuck of maintenance for more time precision, improves the chuck novel chuck in service life.For this reason, the utility model by the following technical solutions: it comprises disk body, has the parcel of central bore, claw, and described disk body has centered cylinder, and described parcel is enclosed within outside the disk body centered cylinder; The central bore wall of described parcel is provided with sheet piece or ring block wear-resisting or minimizing and the friction of disk body centered cylinder.
For solving the problems of the technologies described above, the utility model also can be by the following technical solutions: it comprises disk body, has the parcel of central bore, claw, and described disk body has centered cylinder, and described parcel is enclosed within outside the disk body centered cylinder; Described disk body centered cylinder with position that parcel cooperates in be provided with sheet piece or ring block wear-resisting or minimizing and parcel central bore wall friction.
For solving the problems of the technologies described above, the utility model also can be by the following technical solutions: it comprises disk body, has the parcel of central bore, claw, and described disk body has centered cylinder, and described parcel is enclosed within outside the disk body centered cylinder; The central bore wall of described parcel is provided with the sheet piece or the ring block of wear-resisting or minimizing and the friction of disk body centered cylinder, described disk body centered cylinder with position that parcel cooperates in also be provided with sheet piece or ring block wear-resisting or minimizing and parcel central bore wall friction.
Adopt above scheme, can both reduce parcel and the wearing and tearing at the disk body position that is mated, make parcel keep concentricity with disk body, maintenance chuck precision for more time, prolongation chuck service life.
