[0019] The utility model provides a technical solution: Figure 1-Figure 5 The high-speed open cam indexing mechanism shown includes a machine table 1, a support shaft 2 is fixedly connected to the top of the machine table 1, a rotating disk 3 is rotatably connected to the top of the support shaft 2, a rotating rod 5 is rotatably connected to the bottom of the rotating disk 3, a protective plate 6 is provided on the outside of the rotating disk 3 and the rotating rod 5, an insert block 11 is fixedly connected to the bottom of the protective plate 6, a socket 10 is provided on the machine table 1 near the insert block 11, the insert block 11 is embedded in the socket 10, and a handle 8 is fixedly connected to the side of the insert block 11 away from the rotating rod 5, a support ring 7 is fixedly connected to the outside of the rotating disk 3 near the bottom, the support ring 7 is rotatably connected to one end of the protective plate 6, a connecting rod 17 is fixedly connected to the inside of the rotating rod 5, and support plates 18 are fixedly connected to the two ends of the connecting rod 17, and the support plate 18 is fixedly connected to the top of the machine table 1.

[0020] During operation, the connecting rod 17 is supported by the support plate 18 to rotate above the machine 1, and the connecting rod 17 will drive the rotating rod 5 to rotate, so that the toggle rod 4 can slide inside the toggle groove 9, and then the rotating disk 3 can rotate on the top of the support shaft 2. When the rotating disk 3 rotates, the protective plate 6 can protect the connection and rotation between the rotating disk 3 and the rotating rod 5. When installing the protective plate 6, you can hold the handle 8 to insert the plug 11 into the socket 10, and the support ring 7 can also support the protective plate 6 at the other end, thereby playing a protective effect. This solves the problem that the exposed structure can easily cause danger during high-speed operation, and the operator's clothes or other lightweight materials can be easily caught in it, causing processing hazards, thereby improving the safety of the equipment when in use.

[0021] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In the figure, a toggle groove 9 is provided on the outside of the rotating rod 5, and the toggle groove 9 is arranged in a spiral shape. A toggle rod 4 is fixedly connected to the bottom of the rotating disk 3. There are multiple groups of toggle rods 4 in a circular array at the bottom of the rotating disk 3. The toggle rod 4 is slidably connected to the inside of the toggle groove 9 away from the end of the rotating disk 3. A positioning hole 12 is provided inside the plug block 11, and a sliding groove 14 is provided inside the socket 10 near the positioning hole 12. A positioning block 13 is slidably connected to the sliding groove 14 and the positioning hole 12, and the top of the positioning block 13 is arranged with a beveled surface near the positioning hole 12.

[0022] During operation, the rotating rod 5 will allow the toggle rod 4 to slide along the spiral structure of the toggle groove 9 when it rotates, so that the rotation of the rotating rod 5 can drive the rotating disk 3 to rotate, and the multiple groups of structures of the toggle rod 4 ensure the smooth rotation of the rotating disk 3. When installing the plug block 11, the plug block 11 will squeeze the beveled surface of the positioning block 13, allowing the positioning block 13 to slide into the sliding groove 14. When the plug block 11 is completely inserted into the socket 10, the positioning block 13 is pushed into the positioning port 12, thereby fixing the plug block 11 inside the socket 10, achieving stability when installing the protective plate 6, and solving the problem that the single insertion structure causes the pressure of the protective plate 6 to accumulate on the top of the support ring 7, resulting in severe wear at the contact position between the protective plate 6 and the support ring 7, thereby improving the service life of the protective plate 6.

[0023] See also Figure 4 and Figure 5 In the figure, the positioning block 13 is fixedly connected to the side of the sliding groove 14 with a spring 15, and the end of the spring 15 away from the positioning block 13 is fixedly connected to the inside of the sliding groove 14. A limiting component is arranged inside the spring 15, and the limiting component includes a positioning rod 16, which is arranged inside the spring 15. One end of the positioning rod 16 is fixedly connected to the side of the positioning block 13 away from the positioning port 12, and the positioning rod 16 is slidably connected to the inside of the machine 1. A mounting hole 19 is opened on the top of the machine 1, and there are four groups of mounting holes 19 arranged in a rectangular array.

[0024] During operation, after the plug 11 is inserted into the socket 10, the spring 15 can push the positioning block 13 inside the sliding groove 14 to embed into the positioning port 12, thereby fixing the plug 11 inside the socket 10. When the spring 15 is extended and retracted, the positioning rod 16 can limit the extension and retraction of the spring 15 and the moving position of the positioning block 13. When the machine 1 needs to be installed, the machine 1 can be fixed first by relying on the mounting hole 19 to achieve subsequent installation. The above structure is adopted to achieve the safety of the overall operation of the equipment, solves the problem that the exposed structure easily causes the operator's clothes or other lightweight materials to be caught in it, causing processing hazards, improves the safety of the equipment during use, and can effectively prevent dust from entering.

[0025] Working principle: The connecting rod 17 is supported by the support plate 18 to rotate above the machine 1. The connecting rod 17 drives the rotating rod 5 to rotate, so that the toggle rod 4 slides inside the toggle groove 9, and then the rotating disk 3 rotates on the top of the support shaft 2. When the rotating disk 3 rotates, the protective plate 6 can protect the connection and rotation between the rotating disk 3 and the rotating rod 5. When installing the protective plate 6, you can hold the handle 8 and insert the plug 11 into the socket 10, and the support ring 7 can also support the protective plate 6 at the other end, thereby achieving a protective effect, solving the previous problem of high When the machine is operated at high speed, it is very easy to cause danger. The exposed structure can easily get the corners of the operator's clothes or other lightweight materials into it, causing processing hazards. The safety of the equipment is improved when it is used. When the rotating rod 5 rotates, the toggle rod 4 slides along the spiral structure of the toggle groove 9, so that the rotation of the rotating rod 5 drives the rotating disk 3 to rotate, and the multiple groups of structures of the toggle rod 4 ensure the smooth rotation of the rotating disk 3. When installing the insert block 11, the insert block 11 will squeeze the beveled surface of the positioning block 13, allowing the positioning block 13 to slide into the sliding groove 14. When the insert block 11 is completely inserted into the socket 10, the positioning block 13 is pushed into the positioning hole 12, thereby fixing the insert block 11 inside the socket 10, achieving stability when installing the protective plate 6, solving the problem that the single insertion structure causes the pressure of the protective plate 6 to be concentrated on the top of the support ring 7, resulting in serious wear at the contact point between the protective plate 6 and the support ring 7, and improving the service life of the protective plate 6. After the insert block 11 is inserted into the socket 10, the spring 15 can push the positioning block 13 in the sliding groove 14 to embed into the positioning hole 12, thereby fixing the insert block 11 inside the socket 10. When the spring 15 is extended and retracted, the positioning rod 16 can limit the extension and retraction of the spring 15 and the movement position of the positioning block 13. When the machine 1 needs to be installed, the machine 1 can be fixed first by relying on the mounting hole 19 to achieve subsequent installation. The above structure ensures the safety of the entire equipment during operation, solves the problem that the exposed structure is easily caught by the operator's clothes or other lightweight materials, causing processing hazards, improves the safety of the equipment during use, and can effectively prevent dust from entering.
