Description
Technical field
The utility model relates to a kind of numerical control device technical field, particularly relates to a kind of spindle unit of CNC milling machine.
Background technology
CNC milling machine is a kind of automatic processing device grown up on the basis of general milling machine, and both processing technologys are substantially identical, and also some is similar for structure.CNC milling machine has to be divided into is not with tool magazine and the large class of band tool magazine two.CNC milling machine wherein with tool magazine is also called machining center.CNC milling machine is various informative, though dissimilar CNC milling machine difference to some extent on composition, has many similarities.
Cooling system.The cooling system of lathe is made up of coolant pump, outlet pipe, return pipe, switch and nozzle etc., coolant pump is arranged in the inner chamber of lathe base, cutting fluid is beaten to outlet pipe from liquid storage tank in base by coolant pump, then through nozzle ejection, cools cutting region.Lubricating system and mode.Lubricating system forms by manually moistening tax oil pump, separator, choke valve, oil pipe etc.Lathe adopts periodic lubrication mode, uses manual lubrication oil pump, is lubricated by separator to rack sleeve, in length and breadth direction guiding rail and three-dimensional ball screw, to improve the service life of lathe.From digital control technology feature. because Digit Control Machine Tool have employed servomotor, Applied Digital technology achieves the direct control to lathe execution unit job order and moving displacement, the gearbox designs of traditional machine tool is cancelled or partial cancellation, and thus frame for movement also greatly simplify.Digital controlly mechanical system is also required to have higher transmission stiffness and without drive gap, with the realization of the execution and Control platform of guaranteeing control instruction.Simultaneously. due to improving constantly of computer level and control ability, perform required various miscellaneous functions with a machine tool allowing greater functionality parts simultaneously and become possibility, thus the machinery knot of Digit Control Machine Tool is drawn and is had higher integrated functional requirement than traditional machine tool.From the requirement of Manufacturing Technology Development, along with the appearance of new material and new technology, and market competition is to the requirement of low cost, metal cutting process is just towards cutting speed with precision is more and more higher, production efficiency is more and more higher and the reliable future development of systems grow.This just requires that the Precision of NC Machine Tool grown up on traditional machine tool basis is higher. more too, mechanical mechanism sound, hot rigidity are better for driving power, and work is more reliable, with running continuously and the least possible downtime when can realize long.
Milling head part forms by having level (or stepless) gearbox and milling head two parts.Milling head main shaft supporting is on high-precision bearing. ensure that main shaft has high rotating accuracy and good rigidity; Main shaft is equipped with rapid changing knife nut, and front-end-cone adopts 1 $ 0505 tapering; Main shaft adopts mechanical stepless speed change, and its adjustable range is wide, and stable drive is easy to operate.Braking mechanism can make main shaft brake rapidly, can save non-cutting time, struts locating snap ring main shaft is braked immediately during brake by brake handle.When starting main motor, should note unclamping principal shaft braking handle.Milling head parts are also equipped with the letter of servomotor, interior toothed belt wheel, ball screw assembly, and collar bush, and they form vertical direction (z direction) feeding driving-chain, make main shaft make vertical rectilinear motion.Overall situation and the powerful market demand of benefiting from national renewal equipment manufacture pull, and the situation that technology tremendous development, willingness to invest are surging has appearred in domestic miller industry." 12 " planning will revitalize equipment manufacture as the main contents advancing industrial structure analysis upgrading, and CNC milling machine then becomes one of emphasis revitalizing equipment manufacture.In future, China will give priority at a high speed, accurate, combined numerically controlled golden miller; Heavy type numerical control gold miller; Numerical control special process milling machine; The associated components etc. of large-sized numerical control shaping and punching equipment and CNC milling machine.
The general performance of CNC milling machine, structure, transmission principle and control program must be familiar with before operation, grasp each action button, the function of indicator lamp and operation sequence.Before getting a thorough understanding of whole operating process, do not carry out operation and the adjustment of lathe.Before starting lathe, check that whether lathe electric control system is normal, whether lubricating system is unimpeded, whether oil is good, and fills up lubricating oil by regulation requirement, and whether each operating grip is correct, whether workpiece, fixture and cutter firm grip, check that whether cooling fluid is sufficient, idle running 3 ~ 5 minutes of then clocking over, checks that whether each drive disk assembly is normal, after confirming fault-free, just can normally use., before processing parts, must close inspection machine origin, whether cutter data normal and carry out without Cutting trajectory simulation run.
Current existing CNC milling machine main shaft is at complex structure, and installation and maintenance are comparatively inconvenient, and main shaft debug difficulties, causes certain inconvenience to user simultaneously.
