Description
Technical field
The utility model relates to production technology equipment field, relates in particular to a kind of processing tool of large-scale nonstandard nut.
Background technology
The large-scale nonstandard nut (tapped bore is greater than 24mm) using on the equipment of some special occasions at present, when there is no specialized nut process equipment, generally adopt the processing of common machine oil (gas) filling device, as lathe, planer etc., owing to relating to clamping and the calibration of part in processing, wherein planer can a plurality of parts of time processing, but working (machining) efficiency is lower; Lathe working (machining) efficiency is higher, but nut is processed six faces on lathe, blank both ends of the surface need to be fixed on lathe claw, has the illusive problem of clamping, can not realize calibration accurately simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of processing tool of large-scale nonstandard nut, for using on engine lathe, makes clamping more convenient, and calibration is more accurate, improves the working (machining) efficiency of nonstandard nut.
For achieving the above object, the technical solution of the utility model is:
The processing tool of large-scale nonstandard nut, comprise base, central shaft and spring are jumped pin positioning device for use, central shaft level runs through base, one end of central shaft is provided with workpiece installation position, workpiece is connected with central shaft with nut one by pad one, described central shaft is provided with the calibration shaft shoulder, in the outer rim of the calibration shaft shoulder, around even circumferential, be provided with six indexing troughs, side direction at base is provided with spring jumping pin positioning device for use, spring jumping pin positioning device for use is relative with indexing trough position, the other end of central shaft is provided with spring, spring is provided with sheath outward, one end of sheath is connected with central shaft with nut two by pad two, the other end of sheath is connected with base.
Described spring is jumped pin positioning device for use and is comprised end cap, bearing pin, calibration spring, latch and handle, is provided with calibration spring between bearing pin and end cap, and the outer end of bearing pin is provided with handle and pin hole, is provided with latch in pin hole.
Between described central shaft and base, be provided with copper sheathing one, between central shaft and sheath, be provided with copper sheathing two.
Compared with prior art, the beneficial effects of the utility model are: can be connected with lathe chuck easily, clamping is reliable, can provide six calibration accurately simultaneously, the calibration that makes nut add man-hour regulates fast and accurate, has improved working (machining) efficiency and the quality of nonstandard nut.
