Description
Technical field
This utility model relates to the technical field of component of machine processing, specifically a kind of precise NC lathe gang tool, particularly to its mechanical connecting structure.
Background technology
At present, less than, in the axle class external diameter lathe in machining of 0.02mm tolerance range and grooving process, inevitably producing, owing to Tool changeover exists position error, the phenomenon that outside dimension is unstable, it is necessary to product is carried out very full inspection and meets prescription.In the prior art: being generally adopted two tool sharpenings, its shortcoming is in that 1: unstable product quality: owing to the course of processing exists tool changing, the tool changing error of cutter-exchange mechanism accounts for tolerance range about 30% about 0.005, causes the CPK < 1.3 of outside dimension.2: Product processing cost is high: owing to two cutter process tool cost height long processing times and size are unstable, because size instability needs full inspection in the course of processing, machining period height and percent defective cause processing cost high.
Summary of the invention
The purpose of this utility model is in that to provide a kind of precise NC lathe gang tool, it can by two cutters in its existing processing technique, merge into a cutter, the course of processing is absent from tool changing, avoid the position error of 0.005, and improve processing precision of products and efficiency, avoid production efficiency low and the some shortcomings of unstable product quality, general domestic numerical control lathe precision can reach Production requirement and avoid adopting expensive import high precision machine tool, overcomes the defect and deficiency that exist in above-mentioned prior art.
nullTo achieve these goals: the technical solution of the utility model is: a kind of precise NC lathe gang tool，It is characterized in that: it includes grooving mechanism、Size adjusting parts、Excircle machining mechanism，Described grooving mechanism is by groove cutter pressing plate、Slot blade、Knife holder slot、Groove cutter pedestal、Location square groove composition，Described groove cutter pedestal is opened above knife holder slot，A slot blade it is provided with in this knife holder slot，Groove cutter pedestal be arranged over groove cutter pressing plate，Groove cutter pressing plate、Slot blade is connected with groove cutter pedestal by bolt，One side surface of this groove cutter pedestal offer the first location square groove，Described excircle machining mechanism is by outer diameter blade、External diameter cutter knife holder slot、Second location square groove、Knife bar forms，The front end of this knife bar is provided with a front end，The side of this front end forms depressed part relative to knife bar，The opposite side of this front end forms jut relative to knife bar，The top of this front end offers an external diameter knife holder slot，This external diameter knife holder slot be arranged over outer diameter blade，Outer diameter blade and external diameter knife holder slot are bolted，The side surface position that described front end forms depressed part relative to knife bar offers one second location square groove，Described size adjusting parts have size adjusting cushion block、First location square button、Second location square button composition，One side surface of size adjusting cushion block is provided with one and positions the first location square button that square groove is corresponding with first，The opposite side surface of size adjusting cushion block is provided with one and positions the second location square button that square groove is corresponding with second，Size adjusting cushion block positions square button respectively through first、Second location square button、First location square groove、Second location square groove and groove cutter pedestal、Front end is connected，Described front end、Size adjusting cushion block、Groove cutter pedestal is attached by bolt.Described first location square groove is positioned at the centre bit of a side surface of groove cutter pedestal.Described second location square groove is positioned at described front end and is in depression relative to knife bar the centre of surface position, side in portion.Described first location square button and the second location square button are positioned at the centre bit of the relative two sides of size adjusting cushion block.
Product structure design is reasonable, has following major advantage:
1. simple in construction, more allowing blade replacement is convenient, and between structure, positioning precision is high, grooving mechanism upper surface be provided with knife holder slot can according to different drawing requirements more allowing blade replacement, or whole mechanism change, side is provided with square location square groove, positioning precision is high, and anti-impact force is strong, and it is convenient to change；
2. improve product yield quality: original technique needs two cutters, the course of processing needs tool changing, during because of tool changing, the cutter-exchange mechanism of lathe need to move to tool changing after home, after tool changing, cutter-exchange mechanism moves to again again needs the position of processing that product is processed, cause that to need inspection operation entirely to cause product sequence to increase efficiency man-hour in long processing time and the processing dimension instability therefore course of processing low, owing to being absent from tool changing minimizing tool change time and lathe empty stroke time after using this novel, also reduce lathe resetting error simultaneously and cutter-exchange mechanism tool changing error therefore product processing time improves more than 15%, constant product quality (CPK > 1.67) course of processing is entirely examined and is changed the reduction in man-hour of sampling observation product whole road into；
3. blade can be changed, and reduces production cost, simultaneously dimensionally stable, and process time is short, and efficiency is high, and percent defective is low, the technique being better than two tool sharpenings.
Compared to existing technologies, there is prominent substantive features and marked improvement.
