Lower-moving type numerical control bender belt transmission system of the present utility model, slide block maintains static, and servomotor drives workbench to move upward by belt transmission system and realizes bending campaign, and then workbench steadily resets at Action of Gravity Field with under with the auxiliary traction of transmission.Complete servo belt numerical control bender main transmission relatively of the prior art, has saved the work such as installation, replacing of back-moving spring and spring, and has avoided because of the uneven impact on transmission system control accuracy of back-moving spring elastic force.In addition, belt transmission system of the present utility model, workbench is evenly applied to bending power on workbench by driving-belt and movable belt pulley, make workbench stressed evenly, moment of flexure and deflection little.Therefore lower-moving type numerical control bender belt transmission system of the present utility model has the balance of transmission, response is fast, transmission accuracy is high, workbench is stressed evenly, is out of shape the advantages such as little.
For further improving the stationarity of belt transmission system, the left and right sides of described fuselage is arranged with respectively two servomotors, on the output shaft of every servomotor, before and after fuselage, be respectively equipped with two electrical machine belt pulleys in front and back, belt wheel, movable belt pulley are determined described in being arranged with respectively four groups in the left and right sides of described fuselage and workbench front-back, every described electrical machine belt pulley connect respectively a driving-belt and respectively with correspondence position determine belt wheel and movable belt pulley installs around.The belt transmission system of this structure, two groups of belt transmission systems before and after servomotor synchronously drives, and the front and back of the left and right sides arrange respectively belt transmission system, adopt two servomotors synchronously to drive worktable lifting to move, make the lifting of workbench flat hidden, the power of adopting is even.
For making the front and back driving-belt degree of tightness of same servomotor drive consistent, stressed evenly to guarantee the stationarity of transmission system, corresponding movable belt pulley and determine belt wheel coaxial corresponding setting respectively before and after described fuselage and workbench homonymy, the position that described in every group, the end of driving-belt connects with fuselage is the corresponding regulating wheel that is provided with respectively, two regulating wheels before described fuselage are coaxially corresponding with two regulating wheels after fuselage respectively, and be fixedly connected with two adjustment axle two ends that are rotatably supported on fuselage respectively, the regulating wheel of described same adjustment axle front-end and back-end is contrary with the strip winding fixed form of corresponding driving-belt.In this structure, before and after two driving-belts on corresponding same adjustment axle reverse strip winding fixed form each other, when the degree of tightness power of front and back driving-belt is inconsistent, adjust axle just in time mutually compensates with pine band to micro-certain angle that turns under the effect of taut band, thereby before and after making, the degree of tightness of driving-belt is consistent, and finally guarantees transmission system stationarity.
For further making left and right servomotor synchronously drive workbench left and right sides synchronization lifting, to improve stationarity and the accuracy of transmission system, the described fuselage left and right sides and workbench are slidably connected by vertically disposed guide rail slide block mechanism, the fuselage rail of the left and right sides lead and slide block between be respectively equipped with the grating scale for detection of slide position and sliding speed, described grating scale is connected with CNC control system respectively, and described CNC control system is controlled the output speed of left and right two servomotors according to the signal feedback of left and right two grating scales.In this structure, left and right two grating scales feed back to CNC control system by the slide position detecting and rate signal respectively, CNC control system is sent control signal to two servomotors respectively contrast the position of two slide blocks according to this feedback signal after, to control the output speed of servomotor, thus make workbench steadily, the lifting of precision.
