The utility model discloses a two and half claws of installation on the carriage saddle, through the tight bar of two and half jaw clamps, removal along with the carriage saddle drives bar removal default distance, thereby can automatic next section with the bar after a section of bar is processed into the product and separates this product remove to and treat machining -position progressive, do not need to cut into sectional blank with the bar in advance, the process is simplified greatly, machining efficiency obtains great improvement, it is little to have the space that occupies the lathe, easy installation, the operation is thus simple, tail end that can centre gripping to bar, the bar is kept somewhere fewly, make bar work more thoroughly.
Description
Technical field
This utility model is related to machine tooling equipment technical field, more particularly, to a kind of bar automatic shift for lathe
Device.
Background technology
At present, numerically controlled lathe, in processing, needs to install blank in the jaw of lathe, and general blank is cut by bar
Cut and form, such as：A piece copper rod several meters long it would be desirable to bar is cut into isometric multiple blanks, then by a hair
Blank is put in lathe jaw rotating shaft, is processed, and after being completely processed, finished product is taken out from jaw, and is placed again into another
One blank, goes round and begins again.This processing technique operation is many, complex, leads to working (machining) efficiency low.
Existing occurring in that on the market installs feeder in lathe spindle tail end, this kind of feeder has that volume is big, efficiency is low,
Bar indwelling is many, installation and debugging inconvenience, feeding when the shortcomings of can produce bias.
Content of the invention
The purpose of this utility model is to solve blank complex process based on bar for the current lathe process, processing effect
The low technical problem of rate.
For realizing above utility model purpose, this utility model provides a kind of bar automatic shift device for lathe,
Including handle, described handle is arranged on carriage saddle, and described handle is provided with guide groove, is spaced and is symmetrically inserted with two in described guide groove
Half pawl, each described half pawl includes base and calvus respectively, and described calvus first end is hinged with described base, described calvus second end
It is built in described base by banking stop, outside described calvus, be provided with blade tooth.
Further, each described half pawl is provided with sliver, and each described half pawl is mated with described guide groove by described sliver, makes
Each described half pawl inserts in described guide groove.
Further, also include fishbolt, in the middle part of described guide groove, be provided with the groove with certain depth, described clamping spiral shell
Bolt is through two walls of described groove.
Further, described calvus second end is nearby installed with spring between surface and described base, and described base sets
There is adjusting screw, described adjusting screw is axially arranged along described spring.
Compared with prior art, the beneficial effects of the utility model are：
This utility model passes through to install two and half pawls on carriage saddle, clamps bar by two and half pawls, with carriage saddle
Mobile drive bar moves predeterminable range, thus can be automatically by bar after being processed into product and separate this product at one section of bar
Next section move to station to be processed, be not required in advance bar be cut into sectional blank, operation obtain significantly letter
Change, working (machining) efficiency obtains larger raising, in addition, the overall structure of automatic shift device is simple, small volume, take the space of lathe
Little, easy for installation, simple to operate, can clamp to the tail end of bar, bar indwelling is few so that bar processing is more thorough.
