[0002] A laser engraving machine is a device that uses lasers to engrave and cut. It is widely used in many fields such as industry, art design, and crafts. When laser engraving materials, it is often necessary to position the materials, so a positioning mechanism needs to be set on the laser engraving machine.

The machine includes a base, a top plate fixedly connected to the top of the base, multiple turntables fixedly connected to the side wall of the top plate, a screw rotatably connected inside each turntable, a motor mounted on the side wall of the top plate, the motor's output end fixedly connected to one end of the screw, a connecting block threadedly connected to the outer wall of the screw, a slide frame fixedly connected to the side wall of the connecting block, a sliding shaft slidably connected inside the slide frame, a laser drill bit mounted on the top of the sliding shaft, a connecting column fixedly connected to the side wall of the top plate, and a connecting shaft fixedly connected to the upper surface of the connecting column. This invention, through the cooperation of the turntables, slide frame, and sliding shaft, achieves synchronous horizontal and vertical axis positioning of the engraving machine's positioning system, thereby achieving fast and accurate positioning and significantly improving the overall working efficiency of the laser engraving machine.

[0004] Although the above-mentioned device can position the workpiece by setting up the cooperation between components such as pull rod, rotating wheel, sliding column, rotating plate, and pressure table, the position of the support table is relatively fixed, which makes it unable to position workpieces of different sizes well and is not practical.

An auxiliary rod is fixedly connected to the lower part of the housing. A slider is slidably connected inside the housing, with the screw and slider passing through and threadedly connected. The auxiliary rod and slider also pass through and are slidably connected.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 The present invention provides an embodiment of a laser engraving machine with a positioning structure, comprising a processing table 1 for connecting various components and for placing the workpiece to be processed. Slide rails 11, which can be electrically powered, are fixedly connected to the left and right sides of the top surface of the processing table 1 for adjusting the position of the engraving device 4. A vertical rod 3 is slidably connected to the top of the slide rails 11 for connecting various components. Positioning components 2 are provided on the left and right sides of the top surface of the processing table 1 for positioning the workpiece. The engraving device 4, which is for laser engraving, is located on the upper part of the processing table 1.

[0032] Furthermore, a horizontal guide rail 31 is fixedly connected between the two uprights 3. A vertical guide rail 32 is provided at the front of the horizontal guide rail 31, which is used to adjust the position and height of the engraving device 4. A horizontal guide block 311 is slidably connected to the outside of the horizontal guide rail 31. The vertical guide rail 32 is fixedly connected to the horizontal guide block 311. A vertical guide block 321 is slidably connected to the outside of the vertical guide rail 32. The guide rail and the guide block can be electrically powered. The engraving device 4 is fixedly connected to the vertical guide block 321.

[0033] like Figure 2 - Figure 4 As shown, the positioning component 2 includes a housing 21, which is used to connect various components and is fixedly connected to the processing table 1. A motor 22 is fixedly connected to the front side of the housing 21 to provide power to the component. A screw 23 is fixedly connected to the output end of the motor 22. The left and right sides of the outer wall of the screw 23 are respectively provided with threads in opposite directions. The screw 23 passes through and is rotatably connected to the housing 21. An auxiliary rod 24 is fixedly connected to the lower part of the housing 21 to assist in the movement of the slider 26. The slider 26 is slidably connected inside the housing 21 to drive the movement of the limiting member 27 and the cylinder 25. The screw 23 passes through and is threadedly connected to the slider 26. The auxiliary rod 24 passes through and is slidably connected to the slider 26. A limiting member 27 is provided on the side of the slider 26 near the engraving equipment 4 to help position the workpiece. A cylinder 25 is fixedly connected to the side of the slider 26 away from the limiting member 27 to adjust the position of the limiting member 27 to help position workpieces of different sizes.

[0034] Furthermore, each of the two outer shells 21 has a sliding opening 211 on its opposite side, which is used to cooperate with the movement of the cylinder 25. The output end of the cylinder 25 is provided with a pneumatic rod 251, which is driven by the cylinder 25 and is used to adjust the position of the limiting member 27. The pneumatic rod 251 passes through and is movably connected to the slider 26. The limiting member 27 includes a limiting block 271, which is used to cooperate with the positioning of the workpiece. The pneumatic rod 251 is fixedly connected to the limiting block 271. An anti-slip pad 272, which may be made of rubber, is provided on the side of the limiting block 271 closest to the engraving device 4. It is used for anti-slip. The limiting block 271 has two slots 273 on the side near the anti-slip pad 272, which are used to connect with the locking strip 274. The anti-slip pad 272 has two locking strips 274 on the side near the limiting block 271. The slots 273 and the locking strips 274 are movably connected, which are used to connect the anti-slip pad 272 and the limiting block 271. The locking strip 274 has an auxiliary cavity 275 in the middle, which is used to deform the locking strip 274 to connect the locking strip 274 and the slots 273.

[0035] Working principle: In use, first place the workpiece to be processed on the processing table 1, then turn on the motor 22. The motor 22 will drive the screw 23 to rotate. When the screw 23 rotates, it will drive the two sliders 26 connected to it to move closer to each other. The sliders 26 will slide along the auxiliary rod 24. When the sliders 26 slide, the cylinder 25 connected to it and the limiting member 27 connected to the air rod 251 will be driven to move. Then turn on the cylinder 25 so that the cylinder 25 pushes the limiting member 27 to press the workpiece against it through the air rod 251. Then the workpiece can be engraved. After the processing is completed, simply control the screw 23 to rotate in the opposite direction by the motor 22 so that the two sliders 26 move away from each other and the limiting member 27 releases the workpiece.

[0036] If the anti-slip pad 272 on the limit block 271 is damaged and needs to be replaced, simply pull the anti-slip pad 272 to make it disengage the locking strip 274 from the slot 273, and then insert the locking strip 274 on the new anti-slip pad 272 into the slot 273.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
