Adopt the shaped grooves clamp for machining of technical solution of the present invention, comprise mandrel, mandrel is for carrying pattern and workpiece, mandrel slidably and rotatable, thus mandrel can drive pattern rotate together with workpiece and slide, mandrel is provided with fixed disk, and fixed disk maintains static, and fixed disk is used for carrying out spacing to stage clip, mandrel is provided with pattern, pattern can make mandrel axially move, the right-hand end of pattern is provided with groove, it is circular that the end face of groove surrounds that a center of circle is positioned on mandrel axial line, the bottom undulate of groove, and the lower shape of groove is consistent with the sidewall shape of shaped grooves, thus the axial undulatory motion of mandrel is consistent with the fluctuating of wave, therefore, tool position remains unchanged, under the rotation of mandrel, cutter can process shaped grooves in workpiece outer wall, fixed leg is provided with on the right side of pattern, jacking block is provided with on the left of fixed leg, jacking block and groove bottom offset, jacking block can make mandrel do axial undulatory motion with coordinating of groove, stage clip is provided with between fixed disk and Kao Mi, stage clip applies a pressure to the right to pattern, thus ensure that jacking block and groove offset all the time, right side mandrel being positioned at pattern is provided with axial chute, mandrel is connected with worm gear by flat key, flat key is positioned at chute, flat key can slide in chute, thus worm gear and mandrel can together with rotate, and in the process of rotating, worm gear and mandrel can relative slidings, be provided with worm screw below mandrel, worm and wheel engages, and worm gear coordinates with worm screw mandrel can be made to rotate, mandrel is also provided with the shaft shoulder and clamping screw, and the shaft shoulder and clamping screw cooperation mandrel can by Workpiece clampings.
Workpiece only need to be sheathed on mandrel when implementing and to lock with clamping screw by the present invention, the position of cutter is adjusted again according to the relative position of jacking block and groove, the processing of shaped grooves can be carried out to workpiece, avoid setting-out, and often process a workpiece, installing new workpiece after being dismantled by the workpiece processed can to the processing of new workpiece, and working (machining) efficiency is high, is applicable to producing in enormous quantities; In addition, in process, avoid cutter position under with the naked eye judging, mismachining tolerance is little.
Further, described jacking block is provided with roller, and roller and groove bottom offset.Roller can reduce the frictional force between jacking block and groove, thus alleviates the wearing and tearing of groove bottom.
Further, the left end of described mandrel is also provided with block.Described block can keep away face change jacking block time mandrel and fixed disk come off.
Described mandrel is arranged with expansion sleeve, and workpiece is sheathed on expansion sleeve, and is also provided with elastomeric pad between workpiece and the shaft shoulder.Expansion sleeve and elastomeric pad can make Workpiece clamping better effects if.
