2. Main components of the Machine
Bed, workbench, left and right columns, beams, saddles, rams and other large parts are all made of resin sand molding, high-quality gray iron 250 casting, annealed in hot sand pit→vibration aging→hot furnace annealing→vibration aging→rough machining→ Vibration aging→hot furnace annealing→vibration aging→finishing, completely eliminate the negative stress of the parts, and keep the performance of the parts stable. The Machine has functions such as milling, boring, drilling, countersinking, tapping, etc., and the tool cooling method is external cooling , The Machine contains 6 feed axes, which can realize 4-axis linkage and 6-axis single-action. There are 2 power heads. The axial direction of the Machine and the power head are shown in the figure below.
2.1 The main structure of the axial transmission feed part
2.1.1 X1/X2 axis: The column reciprocates longitudinally along the guide rail of the fixed bed.
X-axis transmission: Driven and controlled by an AC servo motor, the high-precision planetary reducer drives the two columns to move linearly along the X-axis through the ball screw transmission pair.
Guide rail form: Two high-strength precision linear guide rails are laid flat. The precision grade of the ball screw in the transmission pair is C5.
2.1.2 Y1/Y2 axis: The boring and milling power heads I, II and their columns are respectively installed on the high-strength base guide rails on both sides, and reciprocate along the base guide rails along the Y1 and Y2 axes. The AC servo motor is used to drive and control the ball screw transmission pair, drag the saddle to move, and realize the linear movement along the Y axis.
Guide rail form: 4 linear guide rails + ball screw drive. The accuracy grade of the ball screw in the transmission pair is C5, and the semi-closed-loop control is adopted.
2.1.3 Z1/Z2 axis: Boring and milling power heads I, II and their sliding saddles are vertically installed on the front ends of the columns on both sides, and reciprocate along the Z1 and Z2 axes up and down the column guide rails.
Z1-axis transmission: AC servo motor is used to drive and control the high-precision planetary reducer and ball screw transmission pair, and the ram is driven to move linearly along the Z-axis.
Guide rail form: 2 linear guide rail structures are adopted. The accuracy grade of the ball screw in the transmission pair is C5.
2.2 Chip removal and cooling
There are spiral and flat chain chip conveyors installed on both sides under the workbench, and the chips can be automatically conveyed to the chip conveyor at the end through two stages of spiral and chain plates to realize civilized production. There is a cooling pump in the coolant tank of the chip conveyor, which can be used for external cooling of the tool to ensure the performance and service life of the tool, and the coolant can be recycled.
3. Full digital numerical control system:
3.1. With chip breaking function, chip breaking time and chip breaking cycle can be set on the man-machine interface.
3.2. Equipped with the tool lifting function, the tool lifting distance can be set on the man-machine interface. When the distance is reached, the tool is lifted quickly, then the chips are thrown away, and then it is fast forwarded to the drilling surface and automatically converted to work.
3.3. Centralized operation control box and hand-held unit adopt numerical control system and are equipped with USB interface and LCD liquid crystal display. In order to facilitate programming, storage, display and communication, the operation interface has functions such as man-machine dialogue, error compensation, and automatic alarm.
3.4. The equipment has the function of previewing and re-inspecting the hole position before processing, and the operation is very convenient.
4. Automatic lubrication
Machine precision linear guide rail pairs, precision ball screw pairs and other high-precision motion pairs are equipped with automatic lubrication systems. The automatic lubricating pump outputs pressure oil, and the quantitative lubricator oil chamber enters the oil. After the oil chamber is filled with oil, when the system pressure rises to 1.4-1.75Mpa, the pressure switch in the system is closed, the pump stops, and the unloading valve unloads at the same time. When the oil pressure in the road drops below 0.2Mpa, the quantitative lubricator starts to fill the lubricating point and completes one oil filling. Due to the accurate oil supply of the quantitative oil injector and the detection of the system pressure, the oil supply is reliable, ensuring that there is an oil film on the surface of each kinematic pair, reducing friction and wear, and preventing the damage to the internal structure caused by overheating. , to ensure the accuracy and life of the Machine. Compared with the sliding guide rail pair, the rolling linear guide rail pair used in this Machine has a series of advantages:
① High motion sensitivity, the friction coefficient of the rolling guide rail is small, only 0.0025-0.01, and the driving power is greatly reduced, which is only equivalent to 1 of ordinary machinery. /10.
② The difference between dynamic and static friction is very small, and the follow-up performance is excellent, that is, the time interval between the driving signal and the mechanical action is extremely short, which is conducive to improving the response speed and sensitivity of the numerical control system.③It is suitable for high-speed linear motion, and its instantaneous speed is about 10 times higher than that of sliding guide rails. ④ It can realize gapless movement and improve the movement rigidity of the mechanical system. ⑤Produced by professional manufacturers, it has high precision, good versatility and easy maintenance.
5. Machine use environment:
5.1. Environmental requirements for equipment use
Maintaining a constant level of ambient temperature is an essential factor for precision machining.
(1) Available ambient temperature requirements are -10°C to 35°C, when the ambient temperature is 20°C, the humidity should be 40% to 75%.
(2) In order to keep the static accuracy of the Machine within the specified range, the optimum ambient temperature is required to be 15°C to 25°C, and the temperature difference
Must not exceed ±2°C/24h.
5.2 Power supply voltage: 3-phase, 380V, within the range of ±10% voltage fluctuation, power supply frequency: 50HZ.
5.3 If the voltage in the working area is unstable, the Machine should be equipped with a stabilized power supply to ensure the normal operation of the Machine.
5.4 The Machine should have reliable grounding: the grounding wire is a copper wire, the wire diameter should not be less than 10mm², and the grounding resistance is small into 4 ohms.
5.5 In order to ensure the normal working performance of the equipment, if the compressed air of the air source cannot meet the requirements of the air source, it should be installed on the Machine.
Add a set of air source purification device (dehumidification, degreasing, filtering) before the air.
5.6 Keep the equipment away from direct sunlight, vibration and heat sources, high-frequency generators, electric welding machines, etc., so as to avoid Machine production failure or loss of Machine accuracy.
