Before use, the marking body 8 is installed between the two arc blocks, and the two arc blocks are fixed by bolts, so that the marking body 8 is fixedly installed on the mounting seat 9. The marking body 8 uses a laser marking machine in the prior art, and then the gear is placed in the placement groove 14, and the fixing column 15 is located in the keyway at the center of the gear. In this embodiment, the keyway of the gear is a flat keyway, and the shape of the fixing column 15 is adapted to the shape of the flat keyway. The gear is realized by the cooperation of the fixing column 15 and the flat keyway. The gear is fixed to prevent the gear from rotating; on the other hand, the depth of the placement groove 14 is less than the height of the gear, that is, the lower part of the gear is located in the placement groove 14, and the upper part is located outside the placement groove 14 to facilitate the removal of the gear. It should be noted that the height of the fixing column 15 is greater than the depth of the gear, which further ensures that the gear will not move. The gear is fixed by the fixing column 15. When loading and unloading and replacing the gear, it is only necessary to pull the gear out of the fixing column 15 and insert the next corresponding model of gear into the fixing column 15. The operation is simple and the disassembly is convenient, which can effectively save the gear. The replacement time is improved, and the work efficiency is improved; after the gear is fixed, the left and right positions of the marking body 8 can be adjusted by the first drive motor 5, that is, the first drive motor 5 rotates forward, drives the first screw 6 to rotate forward, and the slide 4 moves to the left as a whole through the first connecting block, the first drive motor 5 rotates reversely, and the slide 4 moves to the right; the position of the marking body in the up and down direction is adjusted by the second drive motor 10, that is, the second drive motor 10 rotates forward, drives the second screw 11 to rotate forward, and the mounting seat 9 moves downward through the second connecting block, the second drive motor 10 rotates reversely, and the mounting seat 9 moves upward; the position of the gear in the front and rear directions is adjusted by the third drive motor 16, that is, the third drive motor 16 rotates forward, drives the third screw 17 to rotate forward, and the U-shaped mounting plate 1 is fixed to the ground at this time, so the sliding frame 12 moves forward through the third connecting block 18, the third drive motor 16 rotates reversely, and the sliding frame 12 moves backward; by adjusting the left and right positions, the up and down positions of the marking body 8, and the front and rear positions of the gear, the marking body 8 can accurately mark the designated position of the gear.

[0027] Specifically, in this embodiment, the detachable connection method of the fixing column 15 is as follows: Figure 3-Figure 4As shown, it is preferred that: a connecting column 19 for connecting the fixing column 15 is provided at the center of the placement groove 14, and the connecting column 19 is sequentially sleeved with a gasket 20 and a spring 21 from top to bottom, one end of the spring 21 is fixedly connected to the bottom of the placement groove 14, and the other end is fitted with the lower end surface of the gasket 20, and the upper end of the connecting column 19 is provided with a protrusion 22 for engaging with the fixing column 15, and the protrusion 22 is located at the upper end of the gasket 20. The shape of the fixing column 15 is adapted to the shape of the keyway at the center of the gear, and the bottom surface of the fixing column 15 is provided with a connecting groove 23 adapted to the connecting column 19 and the protrusion 22. When the connecting column 19 is inserted into the connecting groove 23, a fan-shaped through groove 24 is opened on the side of the fixing column 15 corresponding to the protrusion 22, and the fan-shaped through groove 24 is connected with the connecting groove 23.

[0028] When installing the fixing column 15, firstly, make the connection groove 23 at the bottom of the fixing column 15 face directly above the connection column 19, then insert the fixing column 15 downwards, so that the connection column 19 is inserted into the connection groove 23. During the movement of the connection column 19, the bottom surface of the fixing column 15 is tightly attached to the gasket 20, and the spring 21 is compressed downwards. When the upper end of the connection column 19 and the protrusion 22 thereon contact the bottom of the connection groove 23, the fixing column 15 is rotated so that the protrusion 22 at the upper end of the connection column 19 is located in the fan-shaped through groove 24. At this time, under the action of the rebound force of the spring 21, the gasket 20 The bottom surface of the fixing column 15 is squeezed upward and the fixing column 15 is clamped with the protrusion 22; when the fixing column 15 needs to be removed, the fixing column 15 is pressed downward with force, and then the fixing column 15 is rotated so that the protrusion 22 is re-located in the connecting groove 23, and then the fixing column 15 is pulled upward to remove the fixing column 15 from the placement groove 14; when different types of gears need to be marked, since the sizes of the keyways at the centers of different types of gears are different, the detachable connection between the connecting groove 23 and the connecting column 19 can realize the rapid replacement of different types of fixing columns 15, thereby improving work efficiency.
