Abstract
The utility model discloses a drive control device for a travelling car of a core-making machine. The drive control device comprises a machine frame, the travelling car, a drive mechanism and a control mechanism, wherein the travelling car is matched with a guide device arranged on the machine frame. The drive control device is characterized in that the drive mechanism comprises a serve motor arranged on the travelling car, a transmission mechanism connected with an output shaft of the servo motor, an output gear driven by the transmission mechanism, and a rack fixed on the machine frame and arranged to be parallel to a running direction of the travelling car; the output gear is engaged with the rack; the control mechanism comprises a controller, an input and display device and a servo control system. According to the drive control device, the servo motor is arranged, so that the problem that the travelling car of the core-making machine cannot be quickly and stably positioned is solved; due to the adoption of the servo motor, the position and the speed of the car can be determined for control without mechanical limiting and an external sensor.
Description
Technical field
The utility model relates to a kind of control of metal casting machine, is specifically related to a kind of travelling car that core making machine is used and drives the device of controlling.
Background technology
In field of metal casting technology, the making of core is one important technique, and core is generally made by core making machine.In core making machine, have a plurality of stations, core box need to move between each station, and in addition, the air blowing shield of core making machine also needs shift position, so that core making machine can be penetrated respectively sand technique and air blowing curing process on same station.
For realizing above-mentioned movement, in prior art, used air blowing shield dolly and core box dolly, be referred to as travelling car.Travelling car on core making machine, adopts the type of drive such as oil cylinder, oil motor, motor conventionally, and its control mode is for adopting mechanical position limitation, and travelling car is encountered after mechanical position limitation at the volley, and controller is thought and moved into place.This mode travelling car can produce very large noise when colliding with mechanical position limitation, and, in use procedure, along with the wearing and tearing of mechanical position limitation, can cause location not accurate, produce deviation.
On the other hand, in actual use, in order to control the speed of service of travelling car, need outer sensor, the speed of service of dolly is detected, sensor signal is unstable will directly cause the operation of travelling car not steady.
Therefore, in order to strengthen operation stability and the positioning accurate accuracy of travelling car in core making machine, solve travelling car and mechanical position limitation simultaneously and clash into the problems such as noise that cause, need to improve the driving control device of core making machine travelling car.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of driving control device of core making machine travelling car, to guarantee operation stability and the positioning accurate accuracy of travelling car, reduces noise.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of driving control device of core making machine travelling car, comprise frame, travelling car, driving mechanism and controlling organization, described travelling car coordinates with the guider being arranged in frame, described driving mechanism comprises the servomotor being arranged on travelling car, the transmission mechanism being connected with servomotor output shaft, the output gear being driven by transmission mechanism, is fixed on the tooth bar that travelling car traffic direction arranges that is parallel in frame, described output gear and tooth bar engagement; Described controlling organization comprises controller, input and display unit, servo-control system.
Preferred technical scheme, the two ends at the power output shaft of transmission mechanism, are respectively equipped with an output gear, mesh respectively with these two output gears, are respectively arranged with two toothed rack in frame.
In technique scheme, described transmission mechanism is gear drive.
Preferred technical scheme, described controller is PLC controller.Described input and display unit are HMI equipment.Described servo-control system is electrically connected to described controller.
The utility model moves based on servo control mode, its control method is, by HMI equipment, set travelling car range ability and the speed of service, by the required traffic direction of servo-control system computing, range ability and movement velocity, start the operation of servomotor fast and stable and arrive the position that requires.Wherein, described servo-control system capturing and coding device signal, current position coordinates and the speed of service of calculating travelling car, carry out the speed of closed loop and control.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model, by servomotor is set, has solved core making machine travelling car fast and stable orientation problem, adopts servomotor, does not need to use mechanical position limitation and outer sensor can determine position and the speed of dolly, thereby realize, controls.
2. the utility model can pass through HMI equipment input parameter, and by servo-control system, by deviation, the closed loop feedback inputs such as deviation variation rate realize the accurate control to travelling car motion process.
