functional realization
Machine tools are mainly divided into several functional modules
1.Control system.Through dual channels CNC Numerical control system programming is used to achieve automatic machining of machine tools. one The system controls the cross slide tables on both sides. Complete machining of workpieces such as turning and drilling center holes through tool changing and CNC interpolation. Two sets of cross slide tables on the left and right G Instruction programming does not interfere with each other. Start and stop during automatic operation There is a logical relationship at the end. The automatic machining programs on both sides can control the spindle start stop and speed setting Functions such as workpiece clamping, cooling switch, and corresponding linear slide interpolation control.
2. Bed frame.Plays a role in supporting and installing various components. The bed material is HT250， Casting retreat Fire treatment and stress relief through harmonic vibration aging.
3. Spindle and spindle drive.The machine tool spindle is a specially designed double tube clamp double-sided lathe spindle. Precision spindle selection Specialized high-speed spindle bearings. Maximum spindle speed 2000r/Min, spindle radial runout and end face runout< 0.005 Mm. The working temperature rise of the spindle is 25 ℃. The spindle drive motor is Mond 5.5KW Spindle specific servo drive The motor is driven by a synchronous belt with the spindle. pass through CNC The control can be set to different rotations Speed up. The spindle is equipped with a dedicated constant temperature air conditioner, which controls the oil temperature of the hydraulic oil circulating in the spindle to ensure The spindle temperature rise is within the normal range.
4. Feed drive.This machine uses servo motors to convert the rotational motion into linear motion driven by ball screws Precision slide table achieves linear feed during the machining process. The machine tool servo motor is produced by Huazhong CNC Company. Two axes The power of the servo motor feeding the spindle is 10N. m. The power of the lateral displacement servo motor is 10N. m. The ball screw of this machine is selected from the Taiwan Shangyin model DFU3210 Double nut ball screw. The slide table is a ball linear guide.
