Abstract
A grinding machine workpiece clamping device belongs to field of grinding machine workpiece support technology. The problem to be solved is that grinding machine workpiece clamping device with high clamping force and simple structure is provided. The technical scheme to solve the problem includes main shaft sleeve, shell, bearing, stretching screws, location screw caps, conical sleeve, workpiece clamping sleeve and clamping screw caps. The bearing is installed at the pre-and post terminal of the shell. The main shaft sleeve is mounted in the bearing and the location screw caps are installed at the back of the main shaft sleeve. The conical sleeve is installed in the cone shaped hole of inner hole in the front of the main shaft sleeve. The stretching screws are mounted in the internal screw thread of inner hole at the back of conical sleeve. The workpiece clamping sleeve is installed in the cone shaped hole of inner hole in the front of the conical sleeve. The clamping screw caps are mounted on the external screw thread in the front of the conical sleeve. The utility model can be used in grinding machine and its beneficial effects are that the clamping force is high, the structure is simple and it is convenient to use.
Description
Technical field
The utility model belongs to the back rest technical field.
Background technology
General grinding machine, former, back centre withstands workpiece as work support, carry out grinding, but chucking power is big inadequately.The grinding machine that has adopts work holder, by this clamper workpiece is clamped, and carry out grinding, but this kind clamper part is many, and inconvenient operation influences working (machining) efficiency.
Summary of the invention
Technical problem to be solved is to provide a kind of chucking power big, simple in structure, easy to operate grinding machine work holder.
The technical scheme that solves its technical problem is as follows: the grinding machine work holder comprises housing, rear bearing, fore bearing, collar bush, stretching screw, positioning screw cap, conical sleeve, piece-holder sleeve and binding nut.Housing has endoporus, and its front and back ends respectively has bearing block, and housing is installed on the grinding machine.Fore bearing and rear bearing are respectively charged in the antero posterior axis bearing of housing.Collar bush is a cylindrical body, and in the forward and backward bearing of spindle set in housing, collar bush rear end appearance has external screw thread, sets a nut on the external screw thread, and collar bush is positioned in the housing.The collar bush endoporus is divided into three sections, and the leading portion endoporus is pre-large post-small round taper hole, and the stage casing diameter of bore is less.The pre-large post-small conically shaped body that the back segment of conical sleeve adapts for the round taper hole with collar bush leading portion endoporus, the leading portion appearance has external screw thread, the back segment endoporus of conical sleeve has internal thread, its leading portion endoporus is pre-large post-small round taper hole, and the back segment conically shaped body of conical sleeve is packed in the round taper hole of collar bush leading portion endoporus.The stretching screw that diameter is slightly less than collar bush stage casing endoporus internal diameter by after pass collar bush stage casing endoporus forward and pack in the internal thread of conical sleeve back segment endoporus with its screw thread and its tension.The endoporus of piece-holder sleeve is a circular hole, the pre-large post-small conically shaped body that its appearance adapts for the round taper hole with conical sleeve leading portion endoporus, the axial expansion or contraction joints that several front opening back-end closures are arranged on the piece-holder sleeve, piece-holder sleeve are packed in the round taper hole of conical sleeve leading portion endoporus.Pack into the endoporus of piece-holder sleeve of workpiece, binding nut is contained on the leading portion external screw thread of conical sleeve with its internal thread, and workpiece is clamped.
Beneficial effect: the utility model is used for the grinding machine holding workpiece, and its beneficial effect is that chucking power is big, and is easy to operate, and only need tighten or unscrew binding nut can clamp or take off workpiece, and operation is convenient, simple in structure rapidly, low cost of manufacture.
Description of drawings
Fig. 1 is a structure chart of the present utility model.Fig. 1 is described as follows: 1 is collar bush, and 2 is stretching screw, and 3 is positioning screw cap, and 4 is rear bearing, and 5 is fore bearing, and 6 is conical sleeve, and 7 is housing, and 8 is the piece-holder sleeve, and 9 is binding nut, and 10 is expansion or contraction joints.
The specific embodiment
