Technical field
The present invention relates to lathe in machining technical field, specially a kind of lathe in machining is automatically fixed with two-jaw(ed)chuck
Heart clamping device.
Background technology
The clamping of complex outline workpiece, is always one and makes us stubborn problem.Traditional installation way often be unable to do without
The instruments such as dial gauge, tosecan, square carry out centering to surface to be machined, determine that workpiece is correct with respect to cutter on lathe
Position.This centering clamping formula is cumbersome, and the operation technique relation with individual is very big, and low production efficiency, clamping precision is depended on
The technical merit of workman and the precision of survey tool.Therefore, clamping process becomes the process of artisan, becomes technical expert
Process, its situation is highly detrimental to the requirement of current large-scale production.
It is automatic that patent such as the U of application publication number CN 205380283 discloses a kind of lathe in machining two-jaw(ed)chuck
A chuck corpus unguis is respectively equipped with two strip openings on centering and clamping apparatus, chuck end face, chuck corpus unguis passes through two
The cooperation of side rectangular preiection and guide groove in strip opening, makes two chuck corpus unguis can straight line folding, two chucks along guide groove
Fixed respectively on corpus unguis on stationary positioned block on the chuck face between a contiguous block, two contiguous blocks, two contiguous blocks respectively
Fix a soft pawl, helical line toothed disc is arranged in the endless groove of the chuck other end, the helical line screw thread of helical line toothed disc one end with
Chuck corpus unguis corpus unguis tooth is engaged, and the bevel gear of the helical line toothed disc other end is emerging in endless groove, the card that chuck outer wall is provided with
Disk driving hole is communicated with endless groove.But the apparatus structure is relatively simple, practicality is poor, and clamping parts are more inconvenient, for
