Abstract
A beam driving device of a numerical-control turret punch press relates to an improvement on the structures of beam driving devices of numerical-control turret punch presses and is capable of reducing load of lead screws in starting so as to increase stability in driving. A beam is movably connected to a body of the punch press through a Y-axis guide rail, the beam driving device comprises the lead screws, Y-axis lead screw nuts, connecting blocks and Y-axis servo motors, wherein the lead screws, the Y-axis lead screw nuts, the connecting blocks and the Y-axis servo motors are respectively arranged on lower portions of two sides of the beam. Further, the Y-axis servo motors are fixedly connected to the body, the lead screws are parallel to the Y-axis guide rail, one ends of the lead screws are connected to the body through bearings while the other ends of the lead screws are fixedly connected to the Y-axis servo motors, and the Y-axis lead screw nuts are fixedly connected to the bottom surface of the beam through the connecting blocks and are movably connected with the lead screws. The beam is driven to move by driving structures provided with double servo motors and disposed on two sides of a base of the beam. Compared with the mode of driving the lead screws by the single servo motor, the beam driving device has the advantages that the beam of the punch press is stable in running, the service lives of the lead screws are long, and acceleration performance and deceleration performance are improved correspondingly.
Description
Technical field
The utility model relates to the improvement to the crossbeam driving device structure of NC turret punch machine.
Background technology
The crossbeam drive unit of NC turret punch machine adopts the Synchronous Belt Drives pattern not long ago.Afterwards, be not easy to generate pitch error simultaneously for solving the synchronous cog belt tightness, and then cause the low problem of running precision, the applicant 2009.3.24. is to the patent application of " novel cross-beam, 200920041815.9 " of State Intellectual Property Office's proposition.This structure adopts single servo motor to drive the pattern of leading screw, use till today, but we finds in using always; The single servo motor driving mechanism of this structure is placed in the middle of the crossbeam, and single-point is stressed during motion, and power of motor is bigger; During acceleration and deceleration motor is required high; Leading screw is corresponding stressed big, influence the service life of leading screw, and action stability is poor.
The utility model content
The utility model provides a kind of ability to reduce leading screw load when starting to above problem, and then the feasible crossbeam drive unit that drives the NC turret punch machine of stationarity raising.
The technical scheme of the utility model is: said crossbeam is movably connected in through the Y axis rail on the fuselage of said punch press, and said crossbeam drive unit comprises leading screw, Y axial filament thick stick nut, contiguous block and the Y axle servomotor that sets up separately with crossbeam two side lower parts; Said Y axle servomotor is fixedly connected on the said fuselage; Said leading screw be parallel to said Y axis rail, an end through bearing be connected on the fuselage, the other end is fixedly connected said Y axle servomotor; Said Y axial filament thick stick nut is fixedly connected on the bottom surface of said crossbeam through said contiguous block; Said Y axial filament thick stick nut flexibly connects said leading screw.
The utility model adopts two driven by servomotor mechanisms to drive the crossbeam motion; Driving mechanism is placed on the beam base both sides, and for the pattern that former single servo motor drives leading screw, the punch press crossbeam operation of the utility model is more steady; The leading screw life-span is longer, the also corresponding raising of electric property.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the vertical view of Fig. 1,
Among the figure 1, crossbeam, 2, Y axial filament thick stick, 3, Y axle servomotor, 4, contiguous block, 5, Y axial filament thick stick nut, 6, the Y axis rail.
The specific embodiment
The utility model is like Fig. 1, shown in 2; Crossbeam 1 is movably connected in through Y axis rail 6 on the fuselage of said punch press, and said crossbeam drive unit comprises a pair of Y axial filament thick stick 2, a pair of Y axial filament thick stick nut 5, a pair of contiguous block 4 and a pair of Y axle servomotor 3 that sets up separately with 1 liang of side lower part of crossbeam; Said Y axle servomotor 3 is fixedly connected on the said fuselage; Said Y axial filament thick stick 2 be parallel to said Y axis rail 6, an end through bearing be connected on the fuselage, the other end is fixedly connected said Y axle servomotor 3 (both concentrics); Said Y axial filament thick stick nut 5 is fixedly connected on the bottom surface of said crossbeam 1 through said contiguous block 4; Said Y axial filament thick stick nut 5 flexibly connects said Y axial filament thick stick 2.When two servomotors were synchronized with the movement, two leading screws 2 promptly drove crossbeam 1 operation through two Y axial filament thick stick nuts.
