Abstract
The utility model relates to a scheme. The scheme is that a frequency conversion speed regulation motor is used as the power of the main shafts of a lathe, a milling machine, a drilling machine, and a machining center. The scheme is especially suitable for substituting the power scheme that a common motor and a speed change gear set are used as the power of the main shafts in a traditional lathe, a traditional milling machine, a traditional drilling machine, and a traditional machining center.
Description
Technical field the utility model relates to a kind of with the main shaft power scheme of frequency-conversion and speed-regulation motor as lathe, milling machine, drilling machine, machining center, and it is specially adapted to substitute in traditional lathe, milling machine, drilling machine, the machining center with common motor and change-speed gearing group as the main shaft power scheme.
Background technology is present, and known lathe is to make up the power as main shaft by common motor, driving belt, belt pulley, change-speed gearing group.Energising earlier made the common motor rotation when lathe normally moved, and the multi-stage gear that drives in driving belt, the change-speed gearing group by belt pulley rotates, and drove main axis rotation at last and cooperated knife rest and anchor clamps that workpiece is processed.When the needs speed change, essential shutdown is earlier carried out step speed change by the cooperation of the big pinion in the gear change hand lever change change-speed gearing group then, and workpiece processing is proceeded in start again.
This a lot of as the main shaft power scheme shortcoming of lathe, milling machine, drilling machine, machining center with common motor and change-speed gearing group, mainly contain the following aspects:
1, the kinetic energy of motor drives driving belt by belt pulley, and the driving belt interior multi-stage gear of driven gear group again rotates, and just exports spindle power at last.Multistage indirect drive causes electric energy loss serious, and utilization rate of electrical is low, has only 50%～60%.
Gear when 2, lathe moves in driving belt and the gear-box can produce very big noise, makes the worker produce fatigue, causes the personal safety accident easily.
3, use belt pulley, gear-box, a plurality of change-speed gearing, cause production cost to increase, waste a large amount of iron and steel metals.
Influence of noise during 4, owing to change-speed gearing group high speed interlock rotation, the speed of mainshaft under the traditional power scheme the highest can only be 1800 rev/mins.And essentially when carrying out speed change shut down earlier, step speed change is carried out in the cooperation that changes the big pinion in the change-speed gearing group by gear change hand lever then, and start just can be proceeded workpiece processing again again.Cause worker's operation inconvenience, production efficiency is low.
5, to use a large amount of lubricating oil for a long time in the change-speed gearing group, and often need change oil, cause unnecessary waste and environmental pollution.
6, because driving belt and change-speed gearing wear and tear easily, make lathe often need maintenance, maintenance, have a strong impact on the service life of lathe.
The summary of the invention the purpose of this utility model provides a kind of with the main shaft power scheme of frequency-conversion and speed-regulation motor as lathe, milling machine, drilling machine, machining center, and its particular design can overcome in traditional lathe, milling machine, drilling machine, the machining center with common motor and the change-speed gearing group deficiency as the power scheme of main shaft power.Make the functional reliability of above-mentioned serial lathe improve 4～6 times, saves energy 30～35%, production efficiency improves 2～3 times, work noise falls 12 decibels, metal material saves 20～30%, has realized the environmental protection of this class lathe, energy-conservation, consumption reduction breakthroughly, improves machine tool utilization rate, enhance productivity, improved the competitiveness of product on market greatly.
The utility model is achieved in that with frequency-conversion and speed-regulation motor as the main shaft power scheme of lathe, milling machine, drilling machine, machining center by forming with lower member: variable-frequency power sources, single speed or multiple-speed motor.Add man-hour, variable-frequency power sources send electricity to give single speed or multiple-speed motor, directly (inconvenience is positioned in the headstock as motor, can or use single gear to make simple indirect drive by belt pulley and driving belt) makes the machine tool chief axis rotation, cooperates knife rest and anchor clamps that workpiece is processed.When the needs speed change, the operating frequency (number of pole-pairs that can change motor self in case of necessity is to adapt to the job requirement under the new frequency) by variable-frequency power sources change motor realizes stepless linear speed regulation, need not to shut down and just can continue workpiece is processed.
Appended drawings is that the utility model is with the preferred embodiment mechanical schematic diagram of frequency-conversion and speed-regulation motor as the main shaft power scheme of lathe, milling machine, drilling machine, machining center.With frequency-conversion and speed-regulation motor as the main shaft power scheme of lathe, milling machine, drilling machine, machining center by forming with lower member: variable-frequency power sources 1, single speed or multiple-speed motor 2.The connecting relation of above-mentioned parts is: variable-frequency power sources 1 connects with single speed or multiple-speed motor 2, and motor main shaft is directly as machine tool chief axis 4, machine tool chief axis 4 directly and work piece holder 5 join.In the present embodiment, single speed or multiple-speed motor 2 are installed in the headstock 3, and 6 is knife rest, and 7 is lathe bed.
The specific embodiment is such with frequency-conversion and speed-regulation motor as the course of work of the main shaft power scheme of lathe, milling machine, drilling machine, machining center: before the processing, worker first specification requirement and adjustable frequency motor rotating speed formula according to the processing work drawing: rotating speed=frequency * 60 ÷ motor numbers of pole-pairs, select and set suitable motor number of pole-pairs and rotating speed.Start lathe, variable-frequency power sources send electricity to give single speed or multiple-speed motor, directly (inconvenience is positioned in the headstock as motor, can or use single gear to make simple indirect drive by belt pulley and driving belt) makes the machine tool chief axis rotation, cooperates knife rest and anchor clamps that workpiece is processed.When the needs speed change, the operating frequency (number of pole-pairs that can change motor self in case of necessity is to adapt to the job requirement under the new frequency) by variable-frequency power sources change motor realizes stepless linear speed regulation, need not to shut down and just can continue workpiece is processed.
