[0002] Knobs are crucial components in CNC equipment for inputting operational data into the CNC system. Data input is typically achieved by manually turning the knob, during which the CNC system generates corresponding signals. However, most knobs lack physical feedback; workers can only track the data adjustment progress by checking the control system screen, which hinders quick and convenient data adjustments. Summary of the Invention

The housing includes a flange, a front cover, and a rear cover, with the front cover and the rear cover respectively disposed on the front and rear sides of the flange. The rotary transmission assembly includes a gear shaft and a bearing. The gear shaft passes through the flange and its upper end is fixedly connected to the front cover. The bearing is disposed between the gear shaft and the flange. The signal transmission assembly is disposed between the flange and the rear cover and is used to identify and output rotation information of the gear shaft.

[0006] Furthermore, the knob also includes an indexing and positioning component, which is mounted on the flange seat and is used to elastically lock the two teeth of the gear shaft.

The axis of the indexing column is parallel to the axis of the gear shaft. Under normal conditions, the indexing column is located between two teeth of the gear shaft.

[0008] Furthermore, the tips of the gear teeth on the gear shaft are rounded.

[0009] Furthermore, the top surface of the front cover is provided with a scale, and the minimum interval angle of the scale corresponds to the tooth interval angle of the gear shaft.

[0026] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, it will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that the features shown in the figures are not necessarily drawn to scale. Furthermore, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

The terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0028] like Figure 1-3As shown, this embodiment provides a knob for a CNC machine, including a housing and a rotary transmission assembly and a signal transmission assembly disposed within the housing. The housing includes a flange seat 11, a front cover 12, and a rear cover 13, with the front cover 12 and the rear cover 13 respectively disposed on the front and rear sides of the flange seat 11. The rotary transmission assembly includes a gear shaft 21 and a bearing 22. The gear shaft 21 passes through the flange seat 11, and its upper end is fixedly connected to the front cover 12. The bearing 22 is disposed between the gear shaft 21 and the flange seat 11, allowing the front cover 12 to rotate relative to the flange seat 11. The signal transmission assembly is disposed between the flange seat 11 and the rear cover 13, and is used to identify and output the rotation information of the gear shaft 21. The flange seat 11 is mounted on the CNC panel, and the signal transmission assembly is signal-connected to the control system. Thus, turning the front cover 12 drives the gear shaft 21 to rotate, and the signal transmission assembly identifies and outputs the corresponding signal, thereby controlling the control system.

[0029] like Figure 3-4 As shown, as a preferred embodiment, the knob also includes an indexing and positioning component, which is mounted on the flange seat 11 and is used to elastically lock the two teeth of the gear shaft 21 to achieve indexing when the gear shaft 21 rotates.

[0030] like Figure 4 As shown, the indexing and positioning assembly further includes an indexing column 41 and a spring plate 42. Both ends of the spring plate 42 are mounted on the flange seat 11 and located on one side of the gear shaft 21. One side of the indexing column 41 is fixedly connected to the spring plate 42. The axis of the indexing column 41 is parallel to the axis of the gear shaft 21. Under normal conditions, the indexing column 41 is located between two teeth of the gear shaft 21. Under the action of the spring plate 42, when the front cover 12 is twisted, the gear shaft 21 rotates to support the radial movement of the indexing column 41, ensuring that the indexing column 41 does not obstruct the gear shaft 21. After the front cover 12 is stopped from being twisted, the spring plate 42 drives the indexing column 41 to push the gear shaft 21 to correct its position. Furthermore, during the rotation of the gear shaft 21, the indexing and positioning assembly provides tactile feedback to the human hand, allowing workers to better perceive the adjustment process and facilitating quick and accurate data input.

[0031] The typical gear has a flat top, but this has the disadvantage that as the indexing pin 41 rolls over each gear, two jump points are generated at the transition position of the flat top of the gear, affecting the smoothness of the feel and the service life. Therefore, as... Figure 5As shown, as a preferred embodiment, the tips of the teeth of the gear shaft 21 are rounded; thus, when the dome gear rotates through an indexing gear, only one transition jump point is generated, improving smoothness and service life.

[0032] like Figure 1 As shown, as a preferred embodiment, the top surface of the front cover 12 is provided with a scale 121, the minimum interval angle of the scale 121 corresponding to the tooth interval angle of the gear shaft 21, thus providing visual guidance and improving the convenience of operation.

[0033] like Figure 1 As shown, as a preferred embodiment, the circumferential surface of the front cover 12 is provided with anti-slip protrusions 122; preferably, the anti-slip protrusions 122 are honeycomb-shaped; this increases the feel and facilitates operation.

[0034] like Figure 1 As shown, as a preferred embodiment, the top surface of the front cover 12 has a hemispherical recess 123 near the edge. The front cover 12 can be rotated by pressing the recess 123 with a finger, so as to provide multiple operating modes to adapt to various situations in the production workshop.

[0035] like Figure 3 , 6 As shown, in a preferred embodiment, the signal transmission component includes a slit grating 31, a metal circular grating 32, and a circuit board 33. The slit grating 31, the metal circular grating 32, and the circuit board 33 are arranged sequentially at intervals. The slit grating 31 is fixed on the flange seat 11. The lower end of the gear shaft 21 passes through the flange seat 11 and is fixedly connected to the metal circular grating 32. The circuit board 33 is disposed on the rear cover 13. The circuit board 33 receives the light changes generated when the slit grating 31 and the metal circular grating 32 move relative to each other to identify the rotation information of the front cover 12 and transmits the information to the control system.

[0036] like Figure 7 As shown, this embodiment also provides a control panel for CNC equipment, including the aforementioned knob.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
