The technique scheme automatic control level is low, simultaneously, reason owing to the setting of plate shearing machine driving device structure, both sides arrange line slideway rectilinear motion are led, and the increase of knife rest width is restricted, when attempting to make large-scale plate shearing machine, the frame for movement relative complex of device, increase manufacture difficulty, improved manufacturing cost, and can't guarantee shear precision.
Therefore, being necessary to provide a kind of not only can finish the wide cut shearing but also can guarantee that the plate shearing machine drive unit of shear precision adapts to the demand of existing market.
Summary of the invention
Goal of the invention of the present utility model provides a kind of gear-synchronous cog belt CNC shearing machine drive unit, by cleverly design, can finish the shearing of wide plate, can effectively guarantee shear precision simultaneously.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of gear-synchronous cog belt CNC shearing machine drive unit, comprise power set, transmission device, control device and knife rest, described power set are servomotor, described transmission device comprises the gear that is arranged on the servomotor output shaft, the synchronizing jugged wheel, synchronous cog belt, connecting rod and slide block, gear and synchronizing jugged the wheel through Synchronous Belt Drives, described connecting rod one end and synchronizing jugged the wheel are rotationally connected, the other end and described slide block one end are rotationally connected, the slide block other end is fixedly connected with knife rest, and described slide block is spacing by the rectilinear motion position-limit mechanism consistent with the knife rest direction of motion; Described control device is digital control system.
In the technique scheme, the profile of tooth of the synchronizing jugged gear teeth of taking turns and synchronous cog belt meshes successively transmits motion and power, and simultaneously synchronizing jugged the wheel drives slide block band movable knife rack by connecting rod and pump and reach shearing function.Connecting rod can be realized reinforcement one time, and the plate shearing machine ability to work is strengthened.
Further technical scheme is provided with two groups of described power set, and described digital control system is controlled the servomotor synchronization action in these two groups of power set, and the slip in these two groups of power set connects respectively the two ends of movable knife rack.
In two groups of power set, gear, synchronous cog belt are all identical and be arranged symmetrically with the synchronizing jugged parameter of taking turns, and by connecting rod and slide block, can realize that the movable knife rack bi-directional synchronization drives.
In the technique scheme, take servomotor as power source, when digital control system is sent an instruction to two servomotors, servomotor just begins to rotate according to preset instructions, drive two gears and rotate simultaneously, synchronous cog belt is housed on the gear, by synchronous cog belt synchronizing jugged the wheel with gear connected together, and carry out the power amplification, play the effect of long-distance transmissions and control shear precision.The synchronizing jugged drivening rod of taking turns drives slide block and knife rest shearing workpiece.Because the number of teeth of two gears is identical, two synchronizing jugged rotating speeds of taking turns were identical about the gear engagement had guaranteed, about two slide blocks actions that are attached thereto also guarantee synchronously.After shearing was finished, digital control system was sent instruction, motor reversal, and each mechanism resets, and unclamps workpiece, finishes a process.
Because technique scheme is used, the utility model compared with prior art has following advantages:
