Technical field
The utility model relates to a kind of precision machined circular cutter holder that is applicable to major diameter end face lens die.
Background technology
Major diameter end face micro-structural super-precision machine tools is the visual plant that solves the new forms of energy problem in the industry of Developing green low-carbon, also being the important equipment that satisfies following civilian demonstration product, is the infrastructure device that the Fresnel Lenses processing and manufacturing technology of extensive use in development solar energy thermal-power-generating critical system parts and the ultra-thin back projection Display Technique relies on.For the active demand of solar power plant heat collecting element, ultra-thin back projection TV screen and the processing of high-accuracy large-scale concentric circles part, develop a major diameter end face micro-structural super-precision machine tools, realize the Fresnel Lenses Mould Machining.By carrying out the research of large tracts of land micro-structural processing key technology, realize efficient, the Precision Machining of cleaning, environmental protection, the part such as energy-conservation, and in the user produces, realize using.Wherein, the core component that distinguishes with other ultra-precision machine tool is exactly the circular cutter holder of end face lens die processing.B axle flying knife pallet requires to have higher revolution resolution ratio, rotating accuracy, robust motion and stiffness characteristics, makes point of a knife remain at the centre of gyration, reduces the polar coordinates error.
The utility model content
The utility model purpose is to keep B axle circular cutter holder to have higher revolution resolution ratio, rotating accuracy, robust motion and stiffness characteristics in efficient, high accuracy are processed, make point of a knife remain at the centre of gyration, reduce a kind of circular cutter holder structure that is applied to the processing of major diameter end face lens die of polar coordinates error.
A kind of circular cutter holder structure that is applied to the processing of major diameter end face lens die, it is characterized in that, worm screw connects the worm sector plate that drives gyration by it, the worm sector plate is arranged with the with it tool rest bracket of pairing, tool rest bracket is provided with the flat shape guide rail of V-for the gyration of worm sector plate, and provide pretightning force with pressing plate for the worm sector plate, be fixed with on the worm sector plate with its knife rest as the sliding bearing of the centre of gyration, fix promising its on the worm sector plate pressing plate of pretightning force is provided.
This structure adopts servomotor directly to drive the worm screw revolution, drives the revolution of worm sector plate by worm screw; It is the flat shape guide rail of V-that there is the cross section worm sector plate bottom surface, moves in the flat shape guide rail of V-of the tool rest bracket that matches with it, guarantees precision and the rigidity of saddle rotation; And provide pretightning force with pressing plate for the worm sector plate, improve the vibration resistance of knife rest.The utility model cutter frame structure precision is high, have good stability, and is conducive to guarantee crudy.
Description of drawings
Fig. 1 is the circular cutter holder structural principle schematic diagram of major diameter end face lens die processing.
Fig. 2 is the circular cutter holder cross section structure schematic diagram of major diameter end face lens die processing.
The specific embodiment
Be the circular cutter holder structural principle schematic diagram of major diameter end face lens die processing among Fig. 1, wherein 1 is that high accuracy worm screw, 2 is that worm sector plate, 3 is that tool rest bracket, 4 is the V-way face.High accuracy worm screw 1 and worm sector plate 2 forms worm gears, because Worm Wheel System has self-lock ability, and worm sector plate stressing influence indexing accuracy in the time of can be owing to machining; The V-way face 4 of worm sector plate 2 above the tool rest bracket 3 of B axle done gyration, and precision guarantees by the V-way face.
Be the circular cutter holder cross section structure schematic diagram of major diameter end face lens die processing among Fig. 2, wherein 5 be worm gear pressing plate, 6 cutter pressing plates, 7 natural diamond lathe tools, 8 for the level gauge in the flat shape guide rail of V-, 9 be the gaps of worm gear pressing plate and worm sector plate.Wherein, natural diamond lathe tool 7 is pressed on the worm sector plate by cutter pressing plate 6, along with worm sector plate 2 along the V-way face 4 of the flat shape guide rail of V-and the level gauge 8 of the flat shape guide rail of V-, do the high-precision rotary motion, and by worm gear pressing plate 5 maintenance circular cutter holder axial runouts, the rigidity when providing pretightning force to improve cutting; The flat shape guide rail of the V of worm sector plate and tool rest bracket finally guarantees its rotating high accuracy by scraping, and in the scraping process, both are lap tool each other.
The worm sector plate is drive structure of gear worm, and the transmission indexing accuracy is 0.01 °, and the resolution ratio of gyration is 0.001 °.
The worm sector plate is done gyration along the flat shape guide rail of V of the tool rest bracket that matches with it, and the rotating accuracy circular runout is less than 3 μ m, and axial runout is less than 3 μ m.
Pressing plate can pass through the adjusting play for the pretightning force that the worm sector plate provides, and gap adjustment range is 0.5mm.The circular cutter holder structure motion is steady, gapless.
Lathe B axle circular cutter holder needs to realize 1/1000 ° of resolution ratio rotation as the critical component of this project.By its circular index function, cooperate lathe X, Z-axis linkage is realized the micro-structural ultraprecise processing of large-diameter workpiece end face.B axle knife rest servomotor directly drives the worm screw revolution, drives the revolution of worm sector plate by worm screw; Cross section, worm sector plate bottom surface is the flat shape guide rail of V-, moves in the flat shape guide rail of V-of the tool rest bracket that matches with it, guarantees precision and the rigidity of saddle rotation; And provide pretightning force with pressing plate for the worm sector plate, improve the vibration resistance of knife rest.The cutter frame structure precision is high, have good stability, and is conducive to guarantee crudy.
