Abstract
The utility model relates to an electronic-started braking system for an engine lathe, which belongs to the field of mechanical and electronic technology. The braking system comprises an electronic braking soft starter, a lathe electric element, an electric motor, a motor belt pulley, a transmission belt, a spindle box belt pulley and a spindle box, wherein, the lathe electric element comprises an AC contactor, a machine tool transformer and an intermediate relay, the electronic braking soft starter is connected to the electric element and the electric motor of the machine tool through a cable conductor into a whole one, and the electric motor realize power connection with the spindle box through the belt pulley and the transmission belt. When the engine lathe brakes, a triphase AC power supply is converted by the electronic braking soft starter into impulse currents to be input into a stator coil of the electric motor, and the impulse currents enable a motor rotor to generate a powerful reversed electromagnetic field to stop the electric motor from rotating in a positive direction, thereby achieving the purpose of braking. When the engine lathe is started, triphase current signals are input into a microcomputer board of the electronic braking soft starter, and the cutting-in degree of controllable silicon is adjusted by controlling the trigger angle of the controllable silicon in such a manner that soft start currents can be transferred to the motor of the machine tool, thereby achieving the purpose of soft starting. The utility model has the advantages of advanced technology, good braking effect, energy conservation, consumption reduction and the like.
Description
Technical field
The utility model relates to the mechanotronics field, specifically is a kind of engine lathe electric start brake system that has soft start function and electric brake device.
Background technology
Above engine lathe, the axis system of 6140 grades has many group travelling gears and major diameter chuck, load rotating inertia is very big.As the load of direct starter motor drive shaft, start moment and can bring great impact to lathe, be easy to damage travelling gear.Common way is first No Load Start motor, spurs that plate clutch, transferring power are rotated to spindle chuck in groups again.Main spindle box has positive and negative two groups of friction clutches, can distinguish the drive chuck forward or reverse.
Traditional main shaft brake method is: manual joystick by mechanical linkage, when control stick mediates, pulling brake steel band holds brake rim on the power transmission shaft tightly, makes main shaft brake stall.
In summary: the engine lathe tradition starts and brake gear all is to be based upon on frictional drive or the friction catch basis, since the existence of frictional dissipation, clutch disc and brake steel band wear out failure gradually in actual use, braking effect gradually variation, need continuous manual adjustment wearing clearance or change the steel band of loss.
Summary of the invention
The utility model overcomes the deficiency of the technical existence of machine tool tradition brake system, the engine lathe brake that has soft start function and electric brake device start-up system is provided, and the utility model technology has many advantages with original mechanically activated comparing with friction brake.
Engine lathe electric start brake system is made up of electric brake soft initiator, lathe electric part, motor, motor pulley, driving-belt, main spindle box belt pulley, main spindle box, wherein, the lathe electric part comprises A.C. contactor, lathe transformer, auxiliary reclay.This electric start brake system links into an integrated entity the electric brake soft initiator by cable and the former electric part of lathe, motor; Motor is connected with main spindle box by belt pulley, driving-belt.During brake, three-phase alternating-current supply converts pulse current to by the electric brake soft initiator and is input to motor stator line bag, pulse current makes rotor produce powerful reverse electromagnetic field prevention motor and is rotated in the forward, thereby realize that motor quick and precisely brakes, again by the belt pulley transmission, lathe spindle is stopped operating, thereby realize the brake purpose.During startup, micro computer plate with three-phase alternating current signal of telecommunication input electric brake soft initiator, the micro computer plate sends enabling signal to drive circuit, drive circuit sends the three-phase inverse parallel silicon controlled that corresponding control signal acts between power supply and the controlled motor and triggers the angle, change silicon controlled by the size of controlling controllable silicon triggering angle and open degree, thereby the soft start electric current is transported in the machine motor, makes lathe reach the purpose of soft start.
Of the present utility model have suitable effect to be:
1, the utility model advanced technology.It constitutes Based Intelligent Control by one-chip computer, and software program transmits information, and is easy to operate, have characteristics intelligent, hommization.
2, brake starts effective.The utility model all adopts advanced circuit chip, therefore can produce reliable signal, provide powerful brake energy, makes motor in 0.3-1.0 brake fast in second; And can the demand of looking under soft start control be adjusted in 0.53.0 between second stable buffering start, overcome the defective of traditional starting drive staring torque shakiness.
3, energy-saving and cost-reducing.The utility model is than conventional apparatus economize on electricity 20%, and unit annual 0.24 ten thousand degree that economizes on electricity reduces the discharge capacity of carbon dioxide, sulfur dioxide, has the good energy-conservation environment protecting.
Description of drawings
Accompanying drawing is the utility model operation principle flow chart.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, engine lathe electric start brake system includes electric brake soft initiator, lathe electric part, motor, motor pulley, driving-belt, main spindle box belt pulley, main spindle box composition, wherein, the lathe electric part comprises A.C. contactor, lathe transformer, auxiliary reclay.The electric brake soft initiator links into an integrated entity by cable and the former electric part of lathe, motor; Motor realizes that with main spindle box power is connected by belt pulley, driving-belt.During brake, three-phase alternating-current supply converts pulse current to by the electric brake soft initiator and is input to motor stator line bag, pulse current makes rotor produce powerful reverse electromagnetic field prevention motor and is rotated in the forward, thereby realize that motor quick and precisely brakes, again by the belt pulley transmission, lathe spindle is stopped operating, thereby realize the brake purpose.During startup, micro computer plate with three-phase alternating current signal of telecommunication input electric brake soft initiator, the micro computer plate sends enabling signal to drive circuit, drive circuit sends the three-phase inverse parallel silicon controlled that corresponding control signal acts between power supply and the controlled motor and triggers the angle, change silicon controlled by the size of controlling controllable silicon triggering angle and open degree, thereby the soft start electric current is transported in the machine motor, makes lathe reach the purpose of soft start.
