Fig. 2 is the front view of the utility model structural representation.
Among the figure: 1-column, 2-pedestal, 3-handwheel, 4-pedestal, 5-workbench; The 6-main shaft, 7-single shaft head, 8-main shaft belt wheel, 9-main shaft timing belt, 10-balladeur train; 11-spindle motor belt wheel, 12-spindle motor, 13-column ball screw belt wheel, 14-column ball screw, 15-column timing belt; 16-balladeur train servomotor, 17-balladeur train servomotor belt wheel, 18-electric box, 19-digital control system control cabinet, 20-workbench ball screw belt wheel; 21-workbench ball screw, 22-workbench timing belt, 23-workbench servomotor, 24-servomotor belt wheel.
The specific embodiment:
Further describe below in conjunction with the specific embodiment of accompanying drawing the utility model.
As shown in the figure; Pedestal 2 front portions are equipped with pedestal 4; Pedestal 2 is connected with pedestal 4 usefulness screw mandrels, and workbench 5 is installed on the pedestal 4, and 5 of pedestal 4 and workbench are connected with workbench ball screw 21; Can make pedestal 4 and workbench 5 do laterally moving of front and back through handwheel 3; Servomotor and ball screw also can be installed use digital control system and servomotor control to move laterally (Y to), installment work platform servomotor belt wheel 24 and workbench ball screw belt wheel 20 respectively on workbench servomotor 23 and the workbench ball screw 21, by workbench servomotor 23 through synchronizing jugged 22 drive workbench 5 deceleration transmission and mobile (X to); Thereby improve the carry-over moment of workbench servomotor 23, thereby the power that under identical moment requires, can reduce servomotor reaches energy-conservation effect.
Column 1 is installed in pedestal 2 rear portions; Column 1 is equipped with balladeur train 10 through guide rail and column ball screw 14; The moving of balladeur train 10 (Z to) drives column ball screws 14 through column synchronous cog belt 15 by balladeur train servomotor 16 with column ball screw belt wheel 13, balladeur train servomotor belt wheel 17 and rotates and realize; Big or small proportioning through synchronizing jugged belt wheel can be carried out deceleration transmission; Improve the carry-over moment of balladeur train servomotor 16, thereby the power that under identical moment requires, can reduce servomotor reaches energy-conservation effect.
Single shaft head 7, main shaft 6 and spindle motor 12 are installed on the balladeur train 10, main shaft belt wheel 8 is installed on the single shaft head 7, spindle motor belt wheel 11 is installed on the balladeur train 10; Main shaft belt wheel 8 passes through the rotation of main shaft synchronous cog belt 9 by spindle motor 12 driving main shaft 6 with spindle motor 12; Main shaft belt wheel 8 is bigger, and spindle motor belt wheel 11 is less, transmits to realize slowing down; Thereby the power that under identical moment requires, can reduce motor reaches energy-conservation effect; Spindle motor 12 uses variable-frequency motor or main axle servo motors, thereby has reduced mechanical gear, can reach electrodeless variable-speed stably again simultaneously reducing the parts manufacture difficulty.
The digital control system of lathe is installed in the electric box 18 and digital control system control cabinet 19 of column 1 both sides; Digital control system comprises servomotor and the servo-driver of each; And servomotor and servo-driver, spindle dynamo-electric 17 and the variable frequency drives thereof of controlling each realize the motion of each moving-member, rotary part, and digital control system can be used diaxon or three axle systems according to requirements of different users.
The utility model is owing to adopted ball screw; The translational speed and the positioning accuracy of moving component have been improved; And use the rotation that reaches main shaft of moving of digital control system control and driven by servomotor workbench, balladeur train and main shaft; Make the control and the making of lathe oversimplify, the adjustment of the rotation rotating speed of lathe moving-member translational speed and main shaft is also because of having used digital control system no longer complicated.
