[0017] The essential features and advantages of the present invention are further described below with reference to examples, but the present invention is not limited to the examples listed.

[0018] like Figures 1 to 5As shown, a positioning device for a precision engraving machine in this embodiment includes a processing platform 1, a positioning plate 2 is provided on the processing platform 1, and the positioning plate 2 is used to position the material. The positioning plate 2 can be provided with an existing clamping device such as a clamping claw to clamp the material. The positioning plate 2 is provided on a rotating mechanism 3, and the rotating mechanism 3 can drive the positioning plate 2 to rotate, thereby driving the material to rotate. The rotating mechanism 3 includes a base 31, a drive shaft 32, a transmission gear 33, a rotating part 34 and a support plate 35. The drive shaft 32 is horizontally passed through the base 31, and the drive shaft 32 can be driven to rotate by a motor 36. The transmission gear 33 is provided in the base 31 and is sleeved on the drive shaft 32, so that it can rotate synchronously with the drive shaft 32. A cover plate 37 is provided on the base 31 for closing the transmission gear 33. The rotating part 34 has a gear ring 341, and the gear ring 341 is engaged with the transmission gear 33, so that the transmission gear 33 can drive the rotating part 34 to rotate. A connecting rod 342 is provided in the middle of the rotating portion 34, and the support plate 35 is connected to the rotating portion 34 via the connecting rod 342. The processing platform 1 is provided with a sliding assembly 4, which is capable of moving the material. The sliding assembly 4 includes a slider 5 and a guide rail 6. The slider 5 is mounted on the guide rail 6, and the base 31 is mounted on the slider 5. The base 31 is threadedly connected to the screw 41 of the sliding assembly, thereby driving the base's movement through the screw's rotation. The base 31 has a first accommodating cavity 311 and a second accommodating cavity 312 at its bottom. The first accommodating cavity 311 is provided with a mounting seat 7, which is used to connect to a lubricating oil pipe. The slider 5 is mounted in the second accommodating cavity 312. The inlet 51 of the slider 5 corresponds to the oil outlet 71 of the mounting seat 7, allowing lubricating oil to enter the lubricating oil channel within the slider 5 through the oil outlet 71, thereby lubricating the contact surface between the slider and the guide rail. In the above technical solution, the driving shaft 32 drives the rotating portion 34 to rotate, thereby rotating the positioning plate 2, allowing the material to be rotated and adjusted during processing. The slider 5 drives the base 31, thereby linearly moving the positioning plate 2 to adjust the position of the material. Furthermore, by housing the slider 5 in the second accommodating chamber, the base 31 can be lowered from the processing platform 1, while also facilitating access to the lubrication oil circuit. This technical solution facilitates both rotational and linear position adjustment during material processing, providing greater flexibility and convenience.

[0019] In this embodiment, the rotating portion 34 is circular, and the gear ring 341 is an annular tooth disposed at the bottom of the rotating portion 34. The gear ring 341 rotates in a horizontal plane via the transmission teeth 33, thereby driving the rotating portion to rotate. The support plate 35 is provided with a plurality of connection holes 351, which can be screw holes to facilitate assembly and disassembly with the positioning plate 2.

[0020] In this embodiment, the mounting base 7 has an oil inlet 72 and a fluid channel 73. The fluid channel 73 connects the oil inlet 72 and the oil outlet 71. Lubricating oil is input through the oil inlet 72, passes through the fluid channel 73, and is output through the oil outlet 71. The oil inlet 72 is a threaded hole and is arranged on the side of the mounting base 7, thereby facilitating the connection between the delivery pipe 8 and the oil inlet 72. The inner diameter of the input port 51 is larger than the inner diameter of the oil outlet 71. A sealing ring 52 is provided in the input port 51, so that when the slider 5 is mated with the base 31, the oil outlet 71 can dock with the input port 51 and prevent oil leakage. The input port 51 is arranged at the top of the slider 5, and the oil outlet 71 is arranged at the bottom of the mounting base 7, thereby facilitating the connection of the oil ports.

[0021] A positioning device for a precision engraving machine in this embodiment can facilitate rotational and linear position adjustment during material processing, and is more flexible and convenient to use; in addition, it can facilitate the connection of the lubrication oil path of the sliding component.
