Description

Machining machine spindle steady state control module

The invention relates to a processing machine, in particular to a processing machine spindle steady state control module.

In general metal processing machines, before the machining is to be carried out, the warming machine must be carried out first, so that the processing machine can perform the machining operation under the optimal working condition to maintain the machining precision.

The time of the warming machine is mostly based on the experience value, and generally the fixed warming time is adopted, but even if it is the same model, it is affected by the difference of the external temperature (for example, the room temperature is low in winter and the room temperature is high in summer) In the summer, a fixed warm-up time is executed, and the temperature of the warm-up machine may have arrived before the time is reached, which may cause energy consumption. Conversely, a fixed warm-up time is performed in the winter, even if the preset warm-up time has been reached, but the temperature of the warm-up machine has not yet been reached, which will also affect the machining accuracy.

Therefore, the use of a fixed warm-up time is not suitable for different ambient temperatures.

Therefore, the object of the present invention is to provide a steady-state control mode of a processing machine spindle capable of accurately detecting temperature and performing processing in an optimum state. group.

Therefore, the processing machine spindle steady-state control module of the present invention comprises a machine table, a spindle holder slidable relative to the machine table, a spindle unit mounted on the spindle holder, and a spindle unit that can be driven to generate the spindle unit An operating drive unit, the spindle unit having a spindle, a plurality of bearings for rotatably supporting the spindle to the spindle holder, and a collet mounted to the spindle, the control module including a first sensor and a control a first sensor mounted on the spindle holder and adjacent to the spindle for sensing an operating temperature of the spindle, the control unit being electrically connected to the driving unit, the first sensor, and controllable Starting and stopping the driving unit, comparing the first temperature signal with a preset steady state temperature according to the first temperature signal sent by the first sensor, when the first temperature signal is not less than the first temperature signal At steady state temperature, it is a steady state state and a display signal is emitted.

The effect of the invention is that the operating temperature of the spindle can be accurately sensed by using the first sensor, and the first temperature signal and the preset steady state temperature are compared by the control unit, and the display signal can be issued in a steady state state. And remind the operator to start the processing, thereby not only improving the processing accuracy, but also reducing energy consumption.

The spindle unit 130 has a spindle 131, a plurality of bearings 132 that rotatably support the spindle 131 to the spindle holder 120, and a collet 133 mounted to the spindle 131 for holding a cutter 170.

The drive unit 140 is a motor.

The control module includes a first sensor 10, a second sensor 20, a control unit 30, and a human interface 40.

The first sensor 10 is mounted on the spindle mount 130 and electrically connected to the control unit 30 and located on the side of the bearing 132 closest to the collet 133 and located at a proximal end position for sensing the spindle 131 The operating temperature at one end.

The second sensor 20 is mounted on the spindle holder 130 and electrically connected to the control unit 30. The second sensor 20 is away from the collet 133 and located at a distal position relative to the first sensor 10. For sensing the operating temperature of the other end of the spindle 131.

The control unit 30 is electrically connected to the driving unit 140, the first sensor 10 and the second sensor 20, and can control the starting and stopping of the driving unit 140, and according to the first sensor 10 sense Detecting a first temperature signal T1, or sensing a second temperature signal T2 sent by the second sensor 20, comparing the first temperature signal T1 or the second temperature signal T2 with one of presets The steady-state temperature T _{S is a} steady state when the first temperature signal T1 or the second temperature signal T2 is not less than the steady-state temperature T _S , and after a predetermined time delay, a process that can start processing is issued. Display the signal. And the control unit 30 compares the first temperature signal T1 or the second temperature signal T2 with a preset one of the warning temperatures T _H according to the temperature signal sensed by the first sensor T1, when the first temperature signal T1 Or when the second temperature signal T2 is greater than the warning temperature T _H , it is an abnormal state, and immediately sends a warning signal.

The human interface 40 is electrically connected to the control unit 30. The human interface 40 has a display 41 for emitting a display signal and a warning device 42 for emitting the warning signal. The display 41 can be illuminated and audible. The alerter 42 can be different from the display and the sound and sound of the display 41.

Therefore, as shown in FIG. 1 and FIG. 2, when the operator turns on the power of the processing machine and causes the driving unit 140 to start running, the first sensor 10 and the second sensor 20 continuously sense. The spindle 131 is operated at a temperature generated by the first temperature signal T1 and the second temperature signal T2, and the first temperature signal T1 or the second temperature signal T2 is compared with the control unit 30. The steady-state temperature T _{S is set} , when the first temperature signal T1 or the second temperature signal T2 is greater than or equal to the steady-state temperature T _S , that is, the steady-state state that the spindle 131 has reached the optimal machining accuracy, Processing directly or after a predetermined time delay, the display 41 of the human interface 40 can be illuminated and sounded, and the operator can be reminded that processing can begin.

After the processing is continued for a period of time, the driving unit 140 or the spindle 131 may be overheated due to an overload. At this time, the first sensor 10 and the second sensor 20 sense that the spindle 131 is operated. If the first temperature signal T1 or the second temperature signal T2 is greater than the warning temperature T _H , the processing machine is in an abnormal state, and the warning device 42 of the human machine interface 40 immediately sends a warning signal, which has been reminded. The operator machine is abnormal.
