Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] refer to figure 2 , image 3 , The oil bath feeder controller listed in this embodiment includes a motor forward and reverse control circuit, and the motor forward and reverse control circuit includes 5 relays and a single-chip microcomputer. The 5 relays are controlled by the single chip microcomputer to control the forward and reverse rotation of the motor. Of course, 6 relays can be used to control the forward and reverse rotation of the motor. In order to reduce the cost, 5 relays a...

Abstract

The invention relates to a controller of an oil bath feeder, comprising a motor forward and reverse rotation control circuit, wherein the motor forward and reverse rotation control circuit includes 5 relays and a microcontroller, and the microcontroller controls the 5 relays to realize the motor Forward rotation and reverse rotation control; the five relays are connected to the back electromotive force absorption circuit and the relay contact mechanical interlock circuit, the back electromotive force absorption circuit is used to suppress the back electromotive force, and the relay contact mechanical interlock circuit It is used to control whether the motor is only in the forward rotation state or only in the reverse rotation state. The oil bath feeder controller of the present invention uses relays to replace the use of the AC contactor in the traditional controller, and can use PCB wiring, which greatly reduces the volume of the controller and reduces the cost. The relay is controlled by the microcontroller to realize the forward and reverse rotation of the motor, which avoids the damage of the relay contacts and the fracture of the motor shaft caused by the instantaneous state switching of the motor.

Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a controller of an oil bath feeder. Background technique [0002] The oil bath feeder is a kind of CNC lathe feeder. At present, the controller for oil bath feeder is an interlock control circuit assembled from low-voltage electrical components, such as figure 1 As shown, it includes a time relay, two AC contactors, a control transformer, three commonly used low-voltage electrical buttons, and a low-voltage electrical buzzer with lights. The controller mainly controls the forward rotation and reverse rotation of the three-phase asynchronous motor, and the motor load is a gear oil pump. When the feed key is pressed, KM1 absorbs and self-locks, and the motor rotates forward to pump oil to give a certain thrust to a metal bar, which is supplied to the CNC machine tool for processing; after pushing to the end, the hydraulic oil drives the pressure switch, and KM1 jumps of...
