Abstract
The utility model relates to a mechanical machining tool clamp, in particular to a multi-cutter lathe automatic centering tool clamp which comprises a flange base. The flange base is provided with a plurality of bolt holes, a central shaft hole and a cavity. The multi-cutter lathe automatic centering tool clamp is characterized in that internal thread sections are arranged in the cavity of the flange base in a turning mode, an elastic jacket is arranged in the cavity in a threaded connection mode, the inner wall of the elastic jacket is a cone face, locking screws distributed along the radial direction are arranged on the position, directly facing the elastic jacket, on the flange base, a work-piece location pressing cover is arranged at the outer end of the flange base, a ring-shaped boss is designed to be arranged on the outer end face of the location pressing cover, densely-distributed double wedges are designed to be arranged on the outer end face of the ring-shaped boss, a central shaft is arranged in the shaft hole in the flange base in a penetrating mode, penetrates through the elastic jacket, and extends to the exterior of the location pressing cover, a nut and an opening gasket are arranged at the outer end of the central shaft, and an ejection spring is arranged in the elastic jacket. The multi-cutter lathe automatic centering tool clamp solves the problems that centering clamping of push pieces through common chuck clamping is difficult, production efficiency is low and the like, and is mainly applied to work-piece clamping on lathes.
Description
Technical field
The utility model relates to machining tool clamp, especially a kind of multicut lather self-centering clamping tool.
Background technology
For workpiece such as clutch disk core (referring to Fig. 1) with handle (taper handle) structure class, need to be at two faces of cylinder of lathe processing and step end face, normally adopt three-jaw or chuck to cooperate the tailstock thimble to clamp, adopt scroll chuck for push bar structure, although can self-centering, but clamping built on the sand, the operator need to shake tailstock with very large power and hold out against, usually after finishing a face of cylinder processing, need to again shake tailstock holds out against, otherwise workpiece is loosening, affects the machining accuracy of second face of cylinder or step surface; Although and it is comparatively firm to adopt chuck to clamp, can not self-centering, need the workman repeatedly to adjust claw and finish centering, not accurate, efficient is low, and need to shake energetically the tailstock top tight workpiece equally, therefore existing clamping and loading method centering clamps difficulty, and labor strength is large, and production efficiency is low.
Summary of the invention
The purpose of this utility model will solve exactly the centering of Vehicle Processing handle class workpiece and clamp difficulty, and labor strength is large, and the problem that production efficiency is low provides a kind of multicut lather self-centering clamping tool.
Concrete scheme of the present utility model is: a kind of multicut lather self-centering clamping tool, has flange seat, have some bolts hole and central shaft hole and cavity on the flange seat, it is characterized in that: car has internal thread segment in the flange seat cavity, be threaded in the cavity elastic jacket is housed, the elastic jacket inwall is taper surface, and the lock-screw of radial arrangement is housed over against elastic jacket on flange seat; In the flange seat outer end workpiece positioning gland is installed, the outer face of positioning gland is designed with annular boss, is designed with densely covered double wedge on the annular boss outer face; Central shaft is installed in the flange seat axis hole, passes the outside that elastic jacket extends to positioning gland, and the outer end of central shaft is fitted with nut and open washer, and ejector spring is housed in elastic jacket.
Elastic jacket described in the utility model is to be made of two sections of external thread section and resilient sleeve, has at least three expansion breach on the resilient sleeve, and the taper surface in the elastic jacket is positioned at resilient sleeve one side to be arranged, large mouthful outwardly.
The tapering of the inner conical of elastic jacket described in the utility model face is identical with workpiece handle tapering.
The nut of the outer end of central shaft described in the utility model can be made one with central shaft and be ledge structure.
Positioning gland described in the utility model adopts the seam location structure to be connected with flange seat.
Operation principle of the present utility model is: during use, adopt bolt fixedly to dock on flange seat of the present utility model and lathe power transmission dish, and be equipped with hydraulic pressure draw-bar driven force drive plate centre bore at lathe and pass with central shaft in the utility model and be connected.During clamping workpiece is through on the central shaft, the handle section of workpiece puts in the elastic jacket, the step end face of workpiece handle tail end is close to positioning gland outer end annular boss and arranges (referring to Fig. 2), between the nut of workpiece and central shaft outer end, plug open washer, start the lathe hydraulic pull bar, make central shaft draw workpiece and positioning gland to finish clamping by nut and open washer, elastic jacket makes workpiece finish self-centering simultaneously, start the lathe drive plate, the operation knife rest can be finished the multi-cutter process of workpiece, after machining, unclamp hydraulic pressure draw-bar and central shaft takes off open washer, under the effect of ejector spring, workpiece can be deviate from from the spring chuck automatically, workpiece under the fast fetching.
The utility model structure is ingenious, and is reasonable in design, simple and quick, and clamping is light, automatically finishes centering and clamps, and production efficiency improves greatly, compares traditional clamping efficient and improves more than four times.
