Wait. Referring to FIG. 1 , a conventional hand wheel 1 is rotatably provided with a rotor 2 , a magnification adjusting device 3 and a shaft adjusting device 4 . The driving mode of the hand wheel 1 is to use the rotating rotor 2 to generate a pulse signal into the controller as a control command. When the rotor 2 is rotated, the direction of rotation of the rotor 2 determines the positive and negative directions of the output pulse wave. The axis adjustment device 4 can be adjusted to select the servo axis to be driven by adjusting the rate adjusting device 3 to select the magnification of the desired output pulse wave.

However, the conventional hand wheel 1 is made thicker due to the arrangement of the rotor 2, and the user's long-term grip is easy to hand acid. Moreover, it can only generate a single axial pulse wave output, and then drive each servo axis one by one through the switching of the shaft adjusting device 4, and can not simultaneously generate the biaxial pulse wave output to make the spindle simultaneously perform biaxial movement, and operate. More time consuming.

In view of the above, it is necessary to provide a compact and capable biaxially The pulse wave output causes the spindle of the machine tool to simultaneously move the hand wheel with biaxial movement.

A hand wheel includes a body, an input device, a rate adjusting device and a shaft adjusting device. The input device, the speed adjusting device and the shaft adjusting device are all disposed on the body. The input device includes a panel having a plurality of touch points, and a control chip electrically connected to the touch point. The touch point is electrically turned on to output a signal to the control chip, and the control chip receives the signal processed. The pulse signal is outputted, and the shaft adjusting device is electrically connected to the control chip for selecting a servo shaft of the machine tool to be driven, and the shaft adjusting device is provided with a double shaft gear position, and the shaft adjusting device is switched to the double shaft The gear position is electrically connected by any two touch points that are touched to generate a signal, so that the control chip calculates the biaxial distribution amount and simultaneously outputs two sets of pulse wave signals, thereby controlling the spindle of the machine tool to simultaneously perform the double Axial movement.

Compared with the prior art, the hand wheel of the present invention replaces the conventional rotor with a touch device, so that the volume of the hand wheel is relatively light and thin, which does not burden the user for a long time, and can be simultaneously generated. The biaxial pulse wave output causes the spindle of the machine tool to move biaxially simultaneously.

In the first embodiment, the panel 31 is circular, and the touch point 32 is a capacitive touch device and is distributed on the periphery of the panel 31.

The control chip 33 is configured to receive the signal output by each touch point 32, and output a pulse signal to the controller to control the action of the servo motor 34 of the CNC machine tool (not shown) to change the spindle. s position. After receiving the signal sent by each touch point 32, the control chip 33 determines the signals of the adjacent touch points 32 to determine the positive and negative directions of the pulse signal. And it will determine the number of signals received by the touch point 32 to determine the number of pulse signals. In the first embodiment, the control chip 33 has the function of pulse signal generation.

The rate adjusting device 40 is electrically connected to the control chip 33 for adjusting the magnification of the desired output pulse wave. The shaft adjustment device 50 is electrically connected to a control wafer 33 for selecting a servo shaft to be driven.

It should be noted that the hand wheel 10 uses the input device 30 to replace the conventional rotor. The volume of the hand wheel 10 is made lighter and thinner, and does not impose a burden on the user for a long time.

Referring to FIG. 4, when a user's finger (not shown) touches the panel 31 and moves in a clockwise direction for a distance, the finger is electrically connected to the passing touch point 32. At this time, the clockwise adjacent touch points 32 are electrically turned on in sequence to generate a signal output, and the control chip 33 receives a signal to output a positive pulse wave after the processing operation.

Referring to FIG. 5, if the hand wheel 10 is to output a negative pulse wave, a finger (not shown) can be touched on the panel 31 and moved in a counterclockwise direction for a distance. The touch point 32 is electrically turned on. At this time, the touch points 32 adjacent to each other in the counterclockwise direction are electrically turned on to generate a signal output, and the control chip 33 receives the signal and outputs a negative pulse wave after the processing.
