Technical Field
The utility model relates to a prepositioning anchor clamps mechanism, especially a merry go round machine components of a whole that can function independently prepositioning anchor clamps mechanism belongs to machine tool machining production technical field.
Background
In the working process of replacing the workpiece and repeatedly aligning the workpiece, when the non-self-centering fixture is used for processing irregular parts, manual feeding needs to perform re-table alignment on the workpiece every time, so that the workpiece and a main shaft of the vertical lathe are coaxial in the processing process. The alignment times are many, the time is wasted, and the working efficiency is low.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a vertical lathe components of a whole that can function independently prepositioning anchor clamps mechanism saves alignment and beats the table process, improves work efficiency.
For solving the above problems, the specific technical scheme of the utility model is as follows: the split pre-positioning fixture mechanism of the vertical lathe is characterized in that an annular positioning block is fixedly connected to the end face I of a connecting disc, a positioning disc is detachably connected to the end face II of the annular positioning block, a calibration hole is formed in the center of the positioning disc, a positioning mandrel is connected to the inside of the calibration hole in a matched mode and used for conducting coaxial calibration on a workpiece to be machined, a plurality of positioning through holes are formed in the end face of the positioning disc, and the positioning through holes are used for clamping and positioning the workpiece to be machined.
The positioning disc and the annular positioning block are coaxially arranged, and the diameter of the positioning disc is smaller than that of the annular positioning block.
The inner diameter of the calibration hole corresponds to the outer diameter of the positioning mandrel.
The positioning through holes are uniformly distributed in the same angle along the circumferential direction relative to the circle center of the positioning disc.
The positioning disc is connected with the annular positioning block through screws.
The utility model discloses the beneficial effect who brings does: when satisfying artifical material loading, carry out the alignment to the work piece, reduce the work degree of difficulty, improve work efficiency.
