Example Embodiment

[0014] The present invention will be further described in detail below in conjunction with the drawings.

[0015] Such as figure 1 As shown, the back-end cutting tool of the numerical control machine tool of the present invention is located on the machine bed 4, and includes a power tool 2 and a fixed tool 6. The power tool 2 is arranged on the sub-spindle base 1, and the fixed tool 6 is arranged on the tool holder 5. The power tool 2 and the fixed tool 6 are in different planes; the power tool 2 and the sub-spindle 3 are in the same horizontal plane, the power tool 2 is two, and the fixed tool 6 is four. The fixed tool 6 and the sub-spindle 3 cooperate with each other to process materials or parts to be processed, and the power tool 2 is on the sub-spindle base 1 and uses the same power with the sub-spindle 3 to process materials or parts to be processed on the opposite spindle. It enriches the processing methods of CNC machine tools.

Abstract

A numerical control machine tool, comprising an emergency stop control circuit, the emergency stop control circuit includes a relay circuit arranged on the circuit for controlling the rotation of the motor shaft, and also includes a manual emergency stop button connected in series with the relay, the manual emergency stop The button is controlled by the key that controls the general emergency stop button of the CNC machine tool. It also includes an AC contactor connected in series with the relay and the manual emergency stop button and connected with the general power supply circuit of the CNC machine tool. This circuit can effectively prevent the spindle box from falling down, protect the workpiece or the cutter head, improve the performance and safety of the CNC machine tool, and reduce the maintenance rate in the case of a manual emergency stop of the CNC machine tool or a sudden power failure.

Description

technical field [0001] The invention relates to a numerically controlled machine tool. Background technique [0002] In order to increase the speed of the spindle box moving up and down, the existing CNC machine tools generally adopt the method of removing the counterweight. The motor shaft used to control the up and down movement of the spindle box is mainly controlled by a separate motor control circuit. There is a relay on the circuit. When the CNC machine tool is not working, the relay remains disconnected, the control circuit is disconnected, and the motor shaft In the state of being braked, it is locked and cannot rotate (that is, the brake). When the CNC machine tool is powered on, the relay is instructed to close the relay, the control circuit is connected, and the motor shaft can rotate. In the absence of counterweight, when the machine tool stops in an emergency or the motor is suddenly cut off externally, it takes a certain amount of time for the relay on the mot...
