Abstract
The utility model discloses a precise eccentric processing clamp. The precise eccentric processing clamp mainly comprises a clamp body, a positioning block, a gasket, fastening bolts, a chuck, and a clamping pawl; the clamp body is provided with a sliding seat which can move in a radial direction; the sliding seat is fixedly provided with the chuck; the excircle surface of the clamp body is provided with a positioning block which is fixedly connected with the clamp body; the positioning block is provided with a radial fastening bolt which is connected with the sliding seat; and the gasket with different thickness can be arranged between the sliding seat and the positioning block so as to adjust the eccentricity between the chuck and the clamp body.
Description
Technical field
The utility model relates to a kind of mechanical device, is specially the accurate eccentric processing anchor clamps that a kind of lathe is used.
Background technology
At mechanical processing industry; Eccentric part is one of workpiece commonly used in the Machine Design; When its off-centre of processing, normally used method is to utilize the three-jaw self-centering chuck processing work eccentric, i.e. the pad of pad one suitable thickness in a claw of scroll chuck; Clamp workpiece, car (mill) goes out eccentric workpiece then again; The thickness of institute's shimming calculates according to diameter of work size, eccentricity values, claw card mouth portion effective width; For scroll chuck; Especially often the scroll chuck that uses, claw has wearing and tearing slightly, and card mouth portion effective width will change; So be difficult to guarantee the accurate eccentricity values of workpiece, this common scroll chuck is the processing precise eccentric work piece in large quantity.
Summary of the invention
The purpose of the utility model is to provide a kind of eccentric processing anchor clamps of precision.
For realizing above-mentioned purpose; The utility model has adopted following scheme: accurate eccentric processing anchor clamps; Mainly form by clamp body, locating piece, pad, fastening bolt, chuck, claw; The slide that can move radially is set on clamp body, and slide cooperates with clamp body through chute, and slide axially fastens bolt through two and connects with clamp body; Fixedly mount chuck on the slide; On the clamp body periphery a positioning block is set, locating piece and clamp body are fixedly connected, also be provided with on the locating piece one radially fastening bolt connect with slide; Can add the pad of different-thickness between slide and the locating piece, with the offset between adjustment chuck and the clamp body.
During use; A radial bolts and two axial bolts of fastening slide are unclamped, and moving sliding base is put into the pad that thickness equals offset between slide and locating piece; Tighten radially fastening bolt then; At this moment locating piece, pad, slide are close together, and tighten to axially fasten bolt again, are locked at slide on the clamp body; Clamp body is inserted machine tool chief axis, put into chuck to workpiece at last and clamp, so just can carry out turning or grinding, thereby process eccentric workpiece workpiece.
The utility model is provided with slide on clamp body, can drive chuck and move radially, and realizes the eccentric processing to workpiece, and has guaranteed the precision of offset through the pad of accurate grinding.
