Abstract
The invention discloses an intelligent shock-absorbing standard worktable for a machine tool, which comprises magnetorheological fluid, exciters, a solid polymer damping gasket, liquid seals, a digital power source containing microcomputer, a standard worktable, damping connectors and a 3D (three-dimensional) sensor. The 3D sensor and the digital power source containing microcomputer 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 stock-removing machine industry, for installing workpiece to be machined or cutter and as benchmark on lathe.I.e. Intelligent shock-absorbing reference workbench for machine tool.
Background technology
Existing resilient flexibility fixture and solid polymer material isolation fixture, form after buffering that secondary focus, power conversion are very limited, the amplitude of vibration that can meet and vibration frequency scope also very limited.Without adaptive ability.
Summary of the invention
The object of this invention is to provide a kind of self adaptation vibration frequency scope wide, have multiple focus to affect, damping is fast, Intelligent shock-absorbing reference workbench for machine tool that energy conversion efficiency is high.
In order to achieve the above object, present invention employs following technical scheme;
Any machine tool all be unable to do without baseline system, and it directly affects the dimensional accuracy of product, positional precision, form accuracy, surface roughness, working (machining) efficiency, operation length, energy loss, spillage of material, production cost.But all there is relative motion gap in the electric machine rotation of lathe, power transmission, main spindle box gear, gearbox gear and other movement parts, adds asymmetric stress etc. of fixing a cutting tool and result in lathe objective reality vibration source.Process system rigidity one timing, when its eigentone is close or when equaling vibration source frequency, process system chatter will occur, is directed at the state deterioratings such as work piece dimensional accuracy, surface roughness.For solving this kind of problem, the organization plan that the present invention adopts includes; Magnetic flow liquid, driver, polymeric solid damping seal pad, hydraulic seal, the digital power containing microcomputer, table base, reference workbench, damping connector, 3D sensor.3D sensor is arranged on reference workbench, digital power containing microcomputer is arranged in machine tool control device, the bottom surface of this table base connects with the former workbench of lathe or the former mounting plane of knife rest, this table base is provided with driver, polymeric solid damping seal pad, hydraulic seal is installed between driver and reference workbench and is full of magnetic flow liquid betwixt, also magnetic flow liquid is full of between polymeric solid damping seal pad and reference workbench, with damping connector location between this table base and reference workbench, its gap is full of magnetic flow liquid.
The present invention utilizes nanometer magnetofluid and magnetic rheological fluid intelligent material physical property variation characteristic, suspension characteristic, Interface Control characteristic, viscosity characteristics, acoustic characteristic, by this structure and driver thereof, the shock energy produced during machine tool processing workpiece is dissipated and decays.It is within the scope of wide vibration frequency, all also can greatly improve frequency conversion, amount of decrease efficiency from motion tracking, thus machining speed and surface roughness precision are improved greatly, and then improve the production efficiency under specific energy consumption.Effective raising is all kinds of cuts, the machining accuracy of equipment for grinding, obviously strengthening process system relative stiffness.This is of great significance processing industry tool.It is characterized in that: described driver is one or more, and driver is the actuator that magnetic flow liquid produces phase transformation intelligently, and the described magnetic flow liquid that vibration energy is changed is non-newtonian fluid stream mutative damp medium.
Intelligent shock-absorbing reference workbench for machine tool adopt clamping workpiece to be machined (or cutter) reference workbench (7)) and table base (6) between isolated by magnetic flow liquid (1) polymeric solid damping seal pad (3) completely, to make in machining lathe self vibration energy and cut vibration energy in isolation strip because damping action forces vibration frequency significantly to be decayed, thus play obvious frequency conversion effect, again due to apparent viscosity and the magnetic suspension characteristic thereof of intelligent magneto-rheological liquid, the self adaptation vibrations changes such as acoustic characteristic, make multiple focus amplitude, frequency significantly decays in isolation strip and converts heat energy to and distributes, do not cause the impact of secondary focus.And then the dimensional accuracy achieved by workpiece to be machined cutting at one time (or grinding), rough surface precision, shape and positional precision improve greatly.The ability of its absorbing vibration is adjustable or automatically control, and during use at the bottom of little, the production cost of occupied ground, raw material sources is wide.
