Abstract
The utility model relates to an improved motor braking device of lathes in C616 series and C618 series made in the China. The utility model adopts the design method of mechanical-electrical integration, and replaces an original mechanical braking assembly in a foot-operating mode. When an operator operates a handle switch of a power supply of the lathe to cut off the power supply of a motor, and a time delay switch is switched on to supply the electricity to an electric actuating mechanism which is connected with a steel cable of a connecting rod of a cam shoe-type brake in a constant force drawing mode; thus, a belt pulley of the motor is locked by a braking shoe to complete braking action; after the seconds are sustained, the time delay switch can automatically cut off the power supply for the electric actuating mechanism, and the electric actuating mechanism is restored to an original state to cancel the braking state.
Description
The utility model relates to lathe and makes field, the especially improvement of lathe brake apparatus.
Present homemade C616; C618 series lathe all adopts the arrestment mechanism of mechanical pedal plate type; the strength of stepping on by operator's pin spurs the cable wire that connects the cam-type shoe brake; this frame for movement following situation occurs through regular meeting; or since the operator to brake time channel power excessive; make certain parts damages in the pedal brake assembly; or because outside the pedal brake assembly is exposed to; the long-term use and the pedal back-moving spring occurs and lost efficacy; thereby influence the lathe braking or brake later startup once more; even owing to braking or operate miss (as driving anti-car suddenly) damage travelling gear by force; maintenance load is big, the maintenance cost height
The purpose of this utility model is: provide a kind of lathe self-braking device that is applicable to the electromechanical integration of homemade C616, C618 series lathe, to substitute existing foot-operated mechanical type brake assembly fully.
For achieving the above object, the technical solution of the utility model is that this device includes lathe electric power switch, cam-type shoe brake, cable wire, electric operator, delay switch, manual auxiliary switch etc.The cam-type shoe brake place the lathe motor pulley firm in, one end of cable wire is connected in the folding connecting rod of cam-type shoe brake, the other end of cable wire is connected in electric operator, delay switch accesses in the current supply circuit of electric operator, and manually auxiliary switch then is linked in the current supply circuit that is constituted between delay switch self and any two-phase of lathe motor.
Advantage of the present utility model is: 1, by this brake apparatus of dress, do not need former lathe is done any change, do not change the former design performance of lathe; 2, electric operator produces the needed best pulling force of lathe motor braking, thereby reduces the stress of each parts in the braking procedure; 3, the in good time outage of delay switch, the in good time release of electric operator, more easy to the operation of lathe, alleviate operative employee's labour intensity; 4, this brake apparatus electromechanical, simple in structure, dependable performance, cost are lower, and maintenance capacity is little; 5, the protection transmission assembly prolongs service life of equipment.
Accompanying drawing 1: be electrical structure principle schematic of the present utility model.
Introduce most preferred embodiment of the present utility model below in conjunction with accompanying drawing
Present embodiment is electrically connected as shown in Figure 1.The effect of this device brake switch is come to realize by motor power bat-handle switch intrinsic on the lathe.Electric operator is selected tractive magnet YB for use, and (model is: MQ1), the coil of this tractive magnet is fixed on the lathe sidewall by support, the motion block of tractive magnet is connected with an end of cable wire, and the other end of cable wire then is connected in the folding connecting rod of cam-type shoe brake.Delay switch is selected air type time-delay relay KT after the repacking for use, and (model is: JS7), concrete repacking way is that the electro-magnet switch of this model air type time-delay relay is partly pulled down, press dress after the reverses its direction again, when being electrically connected two groups of normally-closed contact series connection on this air type time-delay relay are accessed in the tractive magnet current supply circuit, and the switch delay time was transferred to for 3 seconds.
When needs lathe electric motor starting, move the lathe electric power switch downwards, this moment, motor and air type time-delay relay were all connected power supply, the one side electric motor starting, on the other hand because the adhesive effect of air type time-delay relay solenoid, electromagnetic switch KT2 disconnects, and air delay switch KT1 connects because of suffering oppression, and the circuit loop of tractive magnet disconnects
When needs brake lathe motor, the operator upwards moves lathe electric power switch handle, on the one hand by K switch M cutting-off lathe motor power, also cut off the power supply of repacking back air type time-delay relay coil KT on the other hand, K switch T2 is discharged rapidly, this moment, delay switch KT1 and KT2 connect simultaneously, power to tractive magnet KB, tractive magnet adhesive motion block, motion block produces 3 kilograms pulling force pulling cable wire, and cam-type shoe brake brake shoe is opened, and the lathe motor pulley is braked.The air type time-delay relay is continuing after tractive magnet powered for 3 seconds, delay switch KT1 automatic disconnection, the current supply circuit that cuts off tractive magnet YB.At this moment, the motion block of tractive magnet is released because of outage, and cam-type shoe brake brake shoe shrinks immediately, and the motor pulley braking is cancelled.
When processing work needs the lathe motor and just commentaries on classics, the time and when counter-rotating, stir auxiliary switch S B, disconnect current supply circuit this moment of air type time-delay relay coil KT, when upwards having removed lathe power supply bat-handle switch again and closing the lathe motor power, this brake apparatus is not had an effect.
