Description
Technical field
The present invention relates to precise numerical control machine field, specifically the horizontal automatic regulating apparatus of a kind of numerical control movable girder gantry machine crossbeam.
Background technology
In recent years, the product that China's manufacturing industry is produced is to large-scale and ultra-large type future development, the precision of part is to high accuracy future development, cause thus all kinds of Digit Control Machine Tools more and more to demand large-scale, super-huge precise numerical control machine to industries such as large-scale, heavy, superduty and ultra-large type direction fast development, particularly Aeronautics and Astronautics, wind-powered electricity generation, nuclear powers.Numerical control movable beam type Longmen machine tool is because the range of work is extensively subject to market favor, can crossbeam in moving process, crossbeam drives by the ball-screw of left and right pillar, meet large grinding scope, guarantee high grinding progress, will guarantee that crossbeam can accurately locate in vertical direction.But because two parts such as motor, leading screw that drive in synchronization structure have the difference characteristic from dispatching from the factory, add other non-linear factors, as the impact of frictional force difference, load movement, environmental factor etc., make the movement of gantry frame can not guarantee uniformity, produce the asynchronous error of two synchronizing shafts.Meanwhile, the impact that the mechanical couplings that this Large-scale Mobile parts of crossbeam cause is subject to asynchronous error can cause pullling of diaxon, thereby further affects asynchronous error.Need to set up Biaxial synchronous control model, two servomotors are arranged to rational parameter, and two axles are carried out to logic compensation.
How the levelness of crossbeam guarantees, except good machinery guarantees, designs a set of electronic type self-level(l)ing device and seems extremely important.
Through retrieval, CN102699688 discloses a kind of digital controlled planer machine movable beam type gantry and foundation level control method thereof, it comprises two columns, rigid bar and two ends are arranged on the moving beam on two columns by ball-screw kinematic pair, an independently servomotor is respectively equipped with at the two ends of back timber, ball-screw kinematic pair and position grating scale also form respectively a Closed Loop Control Unit, the Closed Loop Control Unit of both sides is connected with the digital control system of lathe by data/address bus respectively and forms a Full-closed loop servo control system, realize the dynamic level adjustment of moving beam by the Closed Loop Control Unit of both sides, its deficiency is: the one, owing to using two independently Full-closed loop servo control systems at moving beam two ends, the performance of two grating scales in two Full-closed loop servo control systems conventionally has certain tolerance in the time dispatching from the factory, and, there is when mounted artificial alignment error, cause the movement of the gantry frame state that can not be up to the standard, produce the asynchronous error of two synchronizing shafts, affect thus the machining accuracy of lathe.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, a kind of novel structure is provided, adjust simple, machining accuracy is high, horizontal accuracy that can automatic real-time monitoring crossbeam, realize crossbeam dynamically and the horizontal automatic regulating apparatus of the conforming numerical control movable girder gantry machine crossbeam of quiescent levels precision.
The technical solution adopted for the present invention to solve the technical problems is:
The horizontal automatic regulating apparatus of a kind of numerical control movable girder gantry machine crossbeam, be provided with crossbeam and control system, described crossbeam one end is connected with the ballscrew that rolls left on left column, the other end is connected with the right ball-screw on right column, the described ballscrew that rolls left is through left driven by servomotor, described right ball-screw is through right driven by servomotor, described left servomotor is connected with control system respectively with right servomotor, it is characterized in that described crossbeam central horizontal is provided with electrolevel, described electrolevel is connected with numerically controlled control system through connection, be beneficial to the photovoltaic principals by electrolevel, take tranquil liquid level as horizontal plane, automatic real-time measurement crossbeam departs from incline direction and the angle of inclination of horizontal plane, and be translated into digital signal transfers to the computer in control system, by the display screen in control system, the error amount in computer is shown again, simultaneously, control system is called autobalance program, the left servomotor of the lower one end of instruction crossbeam or the action of right servomotor, drive left ball wire cylinder or the rotation of right ball-screw, and then make the level of the Static and dynamic of crossbeam remain uniformity, greatly improve the machining accuracy of lathe.
The present invention is owing to adopting said structure, can automatic real-time monitoring crossbeam horizontal accuracy, realize crossbeam dynamically and the uniformity of quiescent levels precision, there is novel structure, adjust simple, machining accuracy advantages of higher.
accompanying drawing explanation

Reference numeral: crossbeam 1, left column 2, right column 3, left servomotor 4, right servomotor 5, electrolevel 6, connection 7, control system 8.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, the horizontal automatic regulating apparatus of a kind of numerical control movable girder gantry machine crossbeam, be provided with crossbeam 1 and control system 8, described crossbeam 1 one end is connected with the ballscrew that rolls left on left column 2, the other end is connected with the right ball-screw on right column 3, the described ballscrew that rolls left drives through left servomotor 4, described right ball-screw drives through right servomotor 5, described left servomotor 4 is connected with control system 8 respectively with right servomotor 5, it is characterized in that described crossbeam 1 central horizontal is provided with electrolevel 6, described electrolevel 6 is connected with numerically controlled control system 8 through connection 7, be beneficial to by the photovoltaic principals of electrolevel 6, take tranquil liquid level as horizontal plane, automatic real-time measurement crossbeam 1 departs from incline direction and the angle of inclination of horizontal plane, and be translated into digital signal transfers to the computer in control system 8, by the display screen in control system 8, the error amount in computer is shown again, simultaneously, control system 8 is called autobalance program, left servomotor 4 or the right servomotor 5 of instruction crossbeam 1 lower one end move, drive left ball wire cylinder or the rotation of right ball-screw, and then make the level of the Static and dynamic of crossbeam 1 remain uniformity, greatly improve the machining accuracy of lathe.
Embodiment: in accompanying drawing 1, when crossbeam 1 tilts to while affecting machining accuracy, electrolevel is with reference to the accompanying drawings shown in 2, the P that is under pressure of a place, distance one end on the crossbeam 1 that is L in length, 1, crossbeam is at x1, x2 place produces distortion electrolevel 6 and produces potential difference, output bias value, this deviate is transferred to macro-variable corresponding in control system 8, control system 8 judges the height state of left column 2 and right column 3 according to the positive negativity of the macro-variable value reading, control system 8 adopts the mode of high-end fixing low side adjustment to realize horizontal adjustment, the left servomotor 4 on lower one side or right servomotor 5 drive roll left ballscrew or the quantitatively rotation of right ball-screw do, then continue to judge that by electrolevel 6 crossbeam 1 is whether in the horizontal extent requiring, otherwise continue quantitatively rotation, until realize the automatic leveling of crossbeam 1.
