Abstract
The invention discloses an intelligent shock-absorbing standard worktable for a machine tool, which comprises magnetorheological fluid, exciters, a damping gasket, liquid seals, a digital power source, a standard worktable, damping connectors and a 3D (three-dimensional) sensor. The 3D sensor and the digital power source control the exciters to subject the magnetorheological fluid to intelligent energy conversion. Using the intelligent shock-absorbing standard worktable solves the problems that the existing flexible clamp in an elastic structure for damping is unable to sufficiently absorb shock, the elastic structure generates a new shock source in returning, the shock absorption frequency range is narrow, the efficiency fails to increase high and the like. The intelligent shock-absorbing standard worktable is simple in structure and easy in control, shock is automatically tracked, efficiency of frequency variation and amplitude reduction is improved, machining speed is increased greatly, surface roughness is improved, production efficiency by unit energy consumption is improved, machining precision of various cutting and grinding devices is improved, shock frequency and amplitude of process systems are changed, relative rigidity of the process systems is enhanced, and high-precision machining, process shortening and consumption reduction are achieved.
Description
Technical field
The invention belongs to the stock-removing machine industry, be used on lathe installing workpiece to be machined or cutter and as benchmark.It is lathe intelligence shock-absorbing benchmark job platform.
Background technology
Existing resilient flexibility anchor clamps and solid high score material are isolated anchor clamps, and the buffering back forms the secondary focus, power conversion amplitude of vibration and vibration frequency model very limited, that can satisfy is also very limited.No adaptive ability.
Summary of the invention
The purpose of this invention is to provide that a kind of self adaptation vibration frequency scope is wide, that multiple focus influence is arranged, lathe intelligence shock-absorbing benchmark job platform that damping is fast, that energy conversion efficiency is high.
In order to achieve the above object, the present invention has adopted following technical scheme;
Any machine tool all be unable to do without baseline system, and it directly influences dimensional accuracy of products, positional precision, form accuracy, surface roughness, working (machining) efficiency, operation length, energy loss, spillage of material, production cost.But, the motor rotation of lathe, power transmission, main spindle box gear, gearbox gear, and other movement parts all have the relative motion gap, add the asymmetric stress of fixing a cutting tool etc. and caused lathe objective reality vibration source.Process system rigidity one regularly, when its eigentone near or when equaling vibration source frequency, chatter will take place in process system, be directed at state deterioratings such as work piece dimensional accuracy, surface roughness.For solving this type problem, the organization plan that the present invention adopts includes; A kind of non-newtonian fluid rheology resisting medium---(intellectual material) magnetic flow liquid, driver, polymeric solid damping sealing gasket, liquid sealing, digital power, table base, benchmark job platform, damping connector.The 3D sensor is installed on the benchmark job platform; Digital power is installed in the lathe executor; The bottom surface of this table base connects with former workbench of lathe or the former mounting plane of knife rest; Driver, polymeric solid damping sealing gasket are installed on this table base, liquid confidential paper are installed between driver and benchmark job platform and are full of magnetic flow liquid betwixt.Equally, also be full of magnetic flow liquid at polymeric solid damping sealing gasket and benchmark job interstation.With damping connector location, its interstitial fluid is full of magnetic flow liquid between this table base and benchmark job platform.
The present invention utilizes nanometer magnetofluid and magnetic rheological fluid intelligent material rerum natura variation characteristic, suspension characteristic, Interface Control characteristic, viscosity characteristics, acoustic characteristic, and the shock energy that produces when making the machine tooling workpiece through this structure and driver thereof is dissipated and decays.It all can and improve frequency conversion, amount of decrease efficient greatly from motion tracking, thereby cut speed and surface roughness precision are improved greatly in wide vibration frequency scope, and then improves the production efficiency under the specific energy consumption.Effectively improve all kinds ofly cut, the machining accuracy of equipment for grinding, obvious strengthening process system relative stiffness.This has crucial meaning to processing industry.
The benchmark job platform (7) of lathe intelligence shock-absorbing benchmark job platform employing clamping workpiece to be machined (or cutter)) and between the table base (6) isolated by magnetic flow liquid (1) polymeric solid damping sealing gasket (3) fully; Make that lathe self vibration energy is decayed because of damping action forces vibration frequency in the isolation strip with the cutting vibration energy significantly in the cut; Thereby play tangible frequency conversion effect; Again because self adaptations such as the apparent viscosity of intelligent magneto-rheological liquid and magnetic suspension characteristic, acoustic characteristic vibrations variation; Make multiple focus amplitude, frequency significantly decay in the isolation strip and convert heat energy to and distribute, do not cause the influence of secondary focus.And then the dimensional accuracy that workpiece to be machined cutting at one time (or grinding) can realize, rough surface precision, shape and positional precision improve greatly.The ability of its absorbing vibration is adjustable or automatic control, during use at the bottom of little, the production cost of occupied ground, the raw material source is wide.
