The plain-milling machine that has extensively used has the workpiece of special processing request for some, and is in use just cumbersome, especially to the workpiece processing of several intersecting planes, needs clamping work pieces repeatedly, and processing repeatedly just can be completed.In process as several sides of drawing horse owner's frame in processing, just need clamping repeatedly, repeatedly process just and can complete.Low and the crudy of efficient and precision all are difficult to guarantee.
Summary of the invention
The object of the present invention is to provide a kind of production miller, have good stability, precision is good, easy to operate, the advantages such as operating efficiency height.
In order to reach above-mentioned purpose, the invention provides a kind of production miller, it is characterized in that comprising milling unit head, feed system, workpiece slew gear, workpiece hydraulic pressure hydraulic clamping system, the cutting fluid circulatory system, electrical apparatus control system, two three parallel lobe blade milling cutters are installed on its main shaft, one spacer is arranged between two milling cutters, spacer has adjusting device, and index dial adopts stepper motor to drive, start-stop at an arbitrary position.
Described milling power head part is to be driven by three-phase AC asynchronous motor, through three grades of decelerations finally by the power output shaft outputting power.
Described feed system is by forming at the ball screw assembly, of working slider bottom and three-phase hybrid stepping motor, and stepper motor is by driver drives, the Current Control of AC servo motor, and accurately sinusoidal current is exported.
Described workpiece slew gear is to drive one group of worm gear, worm screw rotation by stepper motor.Described worm screw is eccentric, eliminates between the two gap by adjusting with the mounting distance of worm gear, in order to guarantee the precision of transmission.
Described workpiece hydraulic clamping system is to provide hydraulic circuit by hydraulic workstation, pulls by drawing cylinder and completes the clamping of workpiece.
The described cutting fluid circulatory system is carried out the circulation of cutting fluid by gear pump.
Described electrical apparatus control system is by the start-stop of the motor of controlling cutting power head, circulating pump, hydraulic pump and control feed system and the slew gear stepper motor forms.
Described electrical equipment control is comprised of PLC and touch screen human-computer interface; Described PLC has two pulse interfaces, is used for controlling two stepper motors of feed system and workpiece slew gear.
Description of drawings
Fig. 1, Fig. 2 are workpiece schematic diagrames to be processed;
Fig. 3 is the structural representation of lathe.
The specific embodiment
By Fig. 1, shown in Figure 2, be workpiece schematic diagram to be processed, wherein A, B, C, D, E, F are six planes will completing on production miller of the present invention, at first with the centre bore of workpiece as positioning datum, workpiece is fixed on the mandrel of index dial 1 as shown in Figure 3 the hydraulic system workpiece pressing.Note the location original position of workpiece when clamping workpiece.Index dial is to adopt stepper motor to drive, start-stop at an arbitrary position.The present case workpiece is trisection.Two three parallel lobe blade milling cutters 2 have been installed on the main shaft of production miller, one spacer is arranged between the two, the length of spacer is to determine according to two plane-parallel distances of workpiece, spacer has adjusting device, in the situations such as tool wear, can do suitable adjustment, guarantee the precision of workpiece with this.
The milling power head part of lathe is to be driven by the three-phase AC asynchronous motor of 3.5 kilowatts, through three grades of decelerations finally by the power output shaft outputting power.Can reach the output of 12 kinds of rotating speeds through the conversion of gear ratio.Be respectively: 40r/min; 110r/min; 270r/min; 680r/min; 60r/min;
150r/min；380r/min；950r/min；80r/min；200r/min；510r/min；1300r/min。
The feed system of lathe refers to be arranged on the ball screw assembly, of working slider bottom and the moving cell that three-phase hybrid stepping motor forms, stepper motor is by driver drives, adopt the current control mode of AC servo motor, accurately sinusoidal current output makes the every running performance index of stepper motor near AC servo motor.
The workpiece slew gear drives one group of worm gear, worm screw revolute pair by a stepper motor and completes.Wherein worm screw is eccentric design, eliminates between the two gap by adjusting with the mounting distance of worm gear, in order to guarantee the precision of transmission.
The workpiece hydraulic clamping system is to provide hydraulic circuit by a hydraulic workstation, pulls the clamping of paired workpiece by drawing cylinder.
The cutting fluid circulatory system is completed the circulation of cutting fluid by a gear pump.
Electrical apparatus control system is the start-stop of the motor of controlling cutting power head, circulating pump, hydraulic pump and the motion of controlling feed system and rotary system stepper motor.The all-in-one that it is comprised of PLC and touch screen human-computer interface is controlled.PLC has two pulse interfaces, is used for controlling two stepper motors.
Below in conjunction with Fig. 3, the course of work of production miller is further described.
After starting the good workpiece of lathe clamping, working slider 3 is in the driving of stepper motor by lead screw pair, and workpiece continues to move ahead near milling cutter 2, and workpiece can be processed, for example first processes A, two faces of B.When workpiece was machined into the position of drawing requirement, program can allow working slider retreat into certain position automatically, and index dial begins to start, make the workpiece rotating certain angle, this case workpiece is rotation 120 degree, after index dial stops, working slider is close to main shaft again, completes the processing of C, two faces of D.Complete equally the processing of E, two faces of F.After all processed completing in plane to be processed, all driver parts return to original position, prepare for processing next workpiece.Workpiece is released simultaneously, and the operator takes off workpiece.For the workpiece of different size model, as long as mandrel and the cutter changed on index dial just can be satisfied the demand.For other, workpiece of calibration requirement is arranged, just can complete processing request as long as adjust procedure.The present invention has the advantages such as efficient is high, precision good, easy to operate in actual use, is widely used in processing and the making of workpiece.
