[0002] The indexing plate is a crucial accessory for CNC machine tools, primarily used for rotating, indexing, and positioning workpieces. It receives signals or commands from the CNC device to perform rotary indexing or continuous rotary feed motion, thereby assisting the CNC machine in completing the specified machining process. CNC indexing plates are typically used in conjunction with CNC milling machines, vertical machining centers, and other equipment, and are suitable for machining workpieces such as shafts and sleeves. Their use not only improves machining accuracy and efficiency but also expands the application range of CNC machine tools, enabling the smooth completion of complex machining tasks.

[0022] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0024] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] See Figures 1 to 6 As shown, the structure of the present invention is as follows: a CNC indexing plate, including a base plate 1, a shell 101 fixedly arranged on the base plate 1, and a motor 2. A turntable shaft is provided for rotation in the shell 101, one end of the turntable shaft passes through the shell 101 and is connected to the turntable 3, and the other end of the turntable shaft is provided with a worm gear 4. A support seat 5 is fixed in the shell 101, and a worm 6 that cooperates with the worm gear 4 is rotatable on the support seat 5. One end of the worm gear 6 passes through the shell 101 and is provided with a rotating wheel 7. The other end of the worm gear 6 is provided with a reduction assembly 8 that is transmission-connected to the motor 2. Specifically, during debugging, the rotating wheel 7 can be manually rotated, and then the cooperation between the worm gear 4 and the worm 6 can drive the turntable 3 to rotate, which is convenient for controlling the angle of the turntable 3 and making the debugging work easier. During processing, after the motor 2 reduces the speed and increases the torque through the reduction assembly 8, the turntable shaft is driven to rotate through the cooperation of the worm gear 6 and the worm gear 4, thereby driving the turntable 3 to automatically control the angle, thereby greatly improving work efficiency.

[0026] like Figure 2 、 Figure 5 As shown, the reduction assembly 8 includes a first pulley 801 arranged on the worm 6, and a second pulley 802 is provided at the output end of the motor 2. The first pulley 801 is connected to the second pulley 802 through a synchronous belt 803. Specifically, the first pulley 801 is a large pulley, and the second pulley 802 is a small pulley. The small pulley at the output end of the motor 2 drives the large pulley on the worm 6 through the synchronous belt 803, reducing the output speed of the motor 2 and increasing the torque accordingly, thereby improving the load capacity and ensuring that the transmission effect reaches an ideal state.

[0027] like Figure 2As shown, an oil groove 9 is provided on the support seat 5 below the worm 6. Specifically, the oil groove 9 is used to add lubricating oil. When the worm gear 4 and the worm 6 rotate, the worm 6 drives the lubricating oil in the oil groove 9 to lubricate the worm gear 4.

[0028] like Figure 2 As shown, a sensing disk 10 is fixedly provided on the turntable shaft, and a sensor 11 corresponding to the sensing disk 10 is provided on the inner wall of the housing 101. Specifically, the sensing disk 10 rotates synchronously with the turntable shaft. By detecting the rotation of the sensing disk 10, the sensor 11 can detect and measure the motion state of the turntable 3 and various environmental parameters, so as to achieve precise control and data recording.

[0029] like Figure 2 As shown, a notch 12 is provided on the induction disk 10. Specifically, when the turntable 3 needs to be reset to zero, the sensor 11 detects the notch 12 on the induction disk 10 as the zero point.

[0030] like Figure 3 、 Figure 6 As shown, a limit pin 13 is threadedly connected to the shell 101, and a groove 14 corresponding to the limit pin 13 is provided on the turntable 3. Specifically, a plurality of grooves 14 are equidistantly provided on the turntable 3. When the turntable 3 does not need to rotate during processing, the limit pin 13 can be inserted into the corresponding groove 14 to prevent the turntable 3 from rotating and affecting the processing accuracy.

[0031] like Figure 1 As shown, T-slots 301 are spaced apart on the turntable 3. Specifically, the turntable 3 can be installed with various jigs through the T-slots 301, which has a wider range of applications.

[0032] like Figure 4 As shown, ribs 102 are provided at intervals on the bottom of the base plate 1, and a stopper 103 is provided on one side of the rib 102. Specifically, the rib 102 is inserted into the groove on the machine tool workbench, and the stopper 103 abuts against the edge of the workbench, which is used to position the turntable 3 during installation and make the installation more stable to avoid displacement of the dividing plate during processing.

[0033] During specific use and debugging, the wheel 7 can be manually rotated, and then the turntable 3 can be driven to rotate through the cooperation of the worm gear 6, which is convenient for controlling the angle of the turntable 3 and making the debugging work easier. During processing, the motor 2 reduces the speed and increases the torque through the reduction assembly 8, and then drives the worm to rotate. The turntable shaft is driven to rotate through the cooperation of the worm gear 6 and the worm wheel 4, thereby driving the turntable 3 to automatically control the angle, greatly improving work efficiency.

[0034] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
