[0039] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0040] In order to solve the problems of the clamping device 30 in the prior art, such as complex structure, high cost, many parts, inconvenient clamping and use, and small clamping travel range of the clamping device, Figure 1 As shown, this embodiment proposes a laser engraving machine, the bottom of which is a strip-shaped bottom plate 10, and the bottom plate 10 is provided with two guide rails 11 in the extension direction, and the first end of the bottom plate 10 is provided with components such as a support plate 21, a motor 22 and a clamping device 30, which are used to mount the objects to be processed and provide rotational power, and the second end of the bottom plate 10 is installed with a bracket assembly and a rotation support assembly 44, etc., for rotationally supporting the objects to be processed. The assembly formed by the bracket assembly and the rotation support assembly 44, etc. can be slidably positioned and installed on the guide rail 11 to adjust the position of the rotational support of the objects to be processed, and is suitable for objects to be processed of various specifications and sizes.

[0041] Specifically, the present embodiment has two support plates 21, which are respectively installed on both sides of the width direction of the first end of the base plate 10. The two support plates 21 are both vertically arranged, and the motor 22 is rotatably connected between the support plates 21 through a rotating shaft. A knob 23 is provided on one side of the support plate 21. The knob 23 can be manually driven to drive the motor 22 and the clamping device 30 installed on the power end of the motor 22 to rotate horizontally to adjust the pitch angle of the clamping device 30.

[0042] In this embodiment, the support assembly includes a first plate body 41 and a second plate body 42 in an L-shaped structure, wherein a rotating support assembly 44 is provided on the upper side of the first plate body 41, and the rotating support assembly 44 has a rotating support member facing the motor 22, and the second plate body 42 is provided with a waist-shaped hole and is installed with a locking member 43, and the second plate body 42 can slide along the main extension direction of the bottom plate 10 through the guide rail 11 on the bottom plate 10, and can be screwed and locked by the locking member 43 after sliding to a predetermined position. Therefore, the problem of a small adjustment range of the existing laser engraving machine can be solved.

[0043] like Figure 2 As shown, the clamping device 30 in this embodiment is directly mounted on the power end of the motor 22, and the motor 22 can directly drive the clamping device 30 and the object to be processed on the clamping device 30 to rotate, without the need for gear transmission speed change, and better stability. In this embodiment, the connection method between the clamping device 30 and the power end of the motor 22 is not limited, and preferably a detachable connection is made by screws.

[0044] Combination Figure 2 and Figure 3As shown, the main body of the rotating body 31 is a disc-shaped structure, and the disc-shaped structure has three radially opened mounting grooves 311; the number of the sliding body 33 matches the number of the mounting grooves 311 and is three, and the sliding body 33 is slidably installed in the mounting grooves 311, and the sliding body 33 can slide in the radial direction of the disc-shaped structure in the mounting grooves 311. The inner wall of the mounting groove 311 has a guide strip 312, and the main body of the sliding body 33 is a long strip-shaped base 331, and the side of the base 331 has a guide groove 332 adapted to the guide strip 312. Therefore, the sliding body 33 can only move in the radial direction of the disc-shaped structure, and cannot rotate relative to the disc structure, and cannot move axially.

[0045] like Figure 4 and Figure 5 As shown, the sliding body 33 has a plurality of assembly protrusions 333 arranged in a straight radial direction along the disk-shaped structure at the first end surface facing the disk-shaped structure, the adjusting disk 32 is installed at the first end surface of the disk-shaped structure, and the adjusting disk 32 has a spiral protrusion structure 321 at the first end surface facing the disk-shaped structure, and the spiral protrusion structure 321 cooperates with the assembly protrusion 333; when the adjusting disk 32 is rotated, the rotating adjusting disk 32 can drive the spiral protrusion structure 321 to gradually enter the gap between two adjacent assembly protrusions 333, so as to drive multiple sliding bodies 33 to move radially synchronously.

[0046] like Figure 6 As shown, in order to lock the relative position of the adjusting disk 32 and the rotating body 31 and prevent the adjusting disk 32 and the rotating body 31 from rotating relative to each other when the motor 22 drives the clamping device 30 to rotate, the disk-like structure has a tubular structure 313 coaxial with the disk-like structure at the axis center facing the first end, and the adjusting disk 32 is rotatably mounted on the tubular structure 313. The tubular structure 313 also has a fixing member for fixing the relative position of the rotating body 31 and the adjusting disk 32. The fixing member is a positioning ring 35, which is mounted on the tubular structure 313 and has a radially through threaded hole 351. When the adjusting disk 32 is screwed to a suitable position, it is only necessary to push up the positioning ring 35, and then screw the screw into the threaded hole 351 and lock it, so as to lock the relative position of the adjusting disk 32.

[0047] Preferably, an elastic gasket, preferably a rubber ring, is installed between the positioning ring 35 and the adjusting disk 32 to prevent loosening.

[0048] For example, when clamping a ring using the clamping device 30, Figure 2As shown, when the clamping device 30 is used, the three rod-shaped claws 34 are respectively installed on the three sliding bodies 33, and the ring to be processed is sleeved on the free end of the rod-shaped claws 34, and then the adjusting disk 32 is screwed, and the adjusting disk 32 drives the sliding body 33 to move radially outward through the cooperation of the spiral protrusion structure 321 and the assembly protrusion 333, until the claws 34 clamp the ring from the inner ring surface of the ring. Then, the positioning ring 35 is pushed upward to press the adjusting disk 32, and the screw is screwed into the threaded hole 351 and locked, and the clamping device 30 is completed.

[0049] like Figure 7-Figure 9 As shown, the clamping device 30 can also be replaced with different claws 34. One end of each claw 34 is used to be fixed on each sliding body 33, and the other end of each claw 34 is used to clamp the outer wall of each circular part. The claw 34 moves toward or away from the center line of the clamping device, so that each claw 34 can clamp and fix the part to be processed, and then the engraving can be processed.

[0050] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
