Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0028] 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.

[0029] 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 an oil bath feeder controller which comprises a motor continuous and reversing rotation control circuit, wherein the motor continuous and reversing rotation control circuit comprises five relays and a microcontroller. The microcontroller controls the five relays to control the motor continuous rotation and the motor reversing rotation; the five relays are connected with a reverse electromotive force absorbing circuit and a relay contact mechanical interlocking circuit, wherein the reverse electromotive force absorbing circuit is used for inhibiting the reverse electromotive force, and the relay contact mechanical interlocking circuit is used for controlling the motor to be either in a continuous rotation state or in a reversing rotation state. The oil bath feeder controller replaces the application of an alternating current contactor in a traditional controller with the relay and the PCB wire arrangement can be adopted so that volume of the controller is greatly narrowed, and cost is reduced. The microcontroller controls the relays to realize motor continuous rotation and reversing rotation, so that relay contact damage and motor shaft fracture caused by motor instantaneous state switch can be avoided.

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...
