Description

Technical Field

[0001] The utility model relates to the technical field of rotation locking devices, in particular to a rotation locking device and a laser engraving machine. Background Art

[0002] Laser engraving and cutting machines focus the laser light emitted from a laser into a laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach a melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the melted or vaporized material. As the relative position of the beam and the workpiece moves, the material eventually forms a texture or cut, thereby achieving the purpose of engraving or cutting.

[0003] However, the existing laser engraving and cutting head can only be fixed to emit light vertically downward to the surface of the workpiece for engraving, so the laser head cannot be rotated and locked to align with the side cylinder for engraving.

[0004] Therefore, how to realize engraving on the side cylinder so as to fix the laser after it rotates to a certain position is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0024] The utility model provides a rotation locking device, comprising: a housing 10 and a U-shaped fixing frame 20. The housing 10 comprises a housing body and a mounting unit. The mounting unit is arranged on the housing body. The U-shaped fixing frame 20 is mounted on the mounting unit, and the position of the U-shaped fixing frame 20 corresponds to that of the mounting unit.

[0025] The mounting unit includes at least one group of mounting holes.

[0026] In one embodiment, the mounting unit on the housing 10 is a mounting hole provided on the housing 10 .

[0027] In another embodiment, the housing 10 includes two groups of mounting holes.

[0028] The rotation locking device also includes at least one set of locking and fixing units, wherein one set of locking and fixing units includes at least one set of rotation fixing sub-units, wherein one set of rotation fixing sub-units includes a graphite nylon gasket 30, a plug screw 40, and a self-locking nut 50. At least one set of locking and fixing units is used to fix the U-shaped fixing frame 20 on the mounting unit, and at least one set of locking and fixing units is installed in contact with at least one set of mounting holes.

[0029] It should be noted that the graphite nylon gasket 30 includes a graphite nylon gasket 301 and a graphite nylon gasket 302. The graphite nylon gasket 301 and the graphite nylon gasket 302 are respectively arranged on both sides of the shell wall of the shell 10, and are used to fix the screw 40 and the self-locking nut 50, thereby realizing the fixed connection between the shell 10 and the U-shaped fixing frame 20 at a certain point.

[0030] It should also be noted that by setting two sets of rotating fixed sub-units, that is, setting two fixing points of the housing 10 and the U-shaped fixing frame 20, and the two fixing points are symmetrically arranged, the housing 10 and the U-shaped fixing frame 20 can rotate around an invisible axis. The invisible axis is the horizontal connecting line of the two fixing points. Figure 1 , Figure 2 and Figure 3 It can be seen that there are two sets of fixed connection combinations of plug screws 40 and self-locking nuts 50, and two sets of graphite nylon washers 30 are included.

[0031] An embodiment is provided, wherein the rotating stator units are divided into two groups.

[0032] The U-shaped fixing frame 20 includes at least one set of U-shaped frame installation holes.

[0033] In one embodiment, the U-shaped fixing frame 20 includes two groups of U-shaped frame mounting holes.

[0034] The mounting holes on the U-shaped fixing frame 20 correspond to the mounting holes on the housing 10 .

[0035] The locking and fixing unit further includes at least one set of manual locking subunits, wherein one set of manual locking subunits includes a hand screw 60; the hand screw 60 is detachably mounted on the mounting hole of the hand screw 60 on the housing 10. When the hand screw 60 is removed from the mounting hole on the housing 10, the hand screw 60 is movably connected to the U-shaped fixing frame 20 and does not separate.

[0036] An embodiment is provided in which the manual locking subunits are divided into two groups, and include two hand screws 60 .

[0037] An embodiment is provided in which a protrusion structure is provided on the hand screw 60 after passing through the mounting hole of the U-shaped fixing frame 20, and the protrusion structure engages with the mounting hole of the U-shaped fixing frame 20, thereby realizing that the hand screw 60 and the U-shaped fixing frame 20 are movably connected and cannot be separated.

[0038] It should be noted that by movably connecting the hand screw 60 and the U-shaped fixing frame 20 without separation, the hand screw 60 can be manually fixed to the corresponding mounting hole of the shell at any time when the relative position of the U-shaped fixing frame 20 and the shell is changed.

[0039] Please refer to Figure 4 and Figure 1 , Figure 4 for Figure 1 The schematic diagram of the structure of the rotating locking device in the rotating use state is shown.

[0040] The locking and fixing unit also includes at least one set of rotating and fixing sub-units, wherein one set of rotating and fixing sub-units includes a graphite nylon gasket 30, a plug screw 40, and a self-locking nut 50, which are used to connect the shell 10 and the U-shaped fixing frame 20 to achieve relative rotation of the shell 10 and the U-shaped fixing frame 20, and the mutual rotation angle can reach 90°.

[0041] It should be noted that the rotation angle of the U-shaped fixing frame 20 on the horizontal plane can exceed 90°, because the housing 10 needs to be equipped with a generator to facilitate operation on an object, such as laser cutting of an object. Therefore, the U-shaped fixing frame 20 and the housing 10 need to be fixed, and a locking fixing structure, i.e., a hand screw 60, needs to be provided to facilitate the use of the rotating fixing subunit.

[0042] In one embodiment, a plurality of mounting holes for hand screws 60 are provided on the housing 10 , so that the housing 10 can be fixed at a plurality of angles.

[0043] The utility model provides a laser engraving machine in a second aspect. The laser engraving machine (not shown) comprises a body (not shown) and a generator. The body comprises a rotation locking device. One end of the generator is installed in the housing.

[0044] Compared with the prior art, the utility model provides a rotation locking device and a laser engraving machine (not shown). A U-shaped fixing frame 20 is arranged on the housing 10 of the rotation locking device, wherein the U-shaped fixing frame 20 is used to connect with the body of the laser engraving machine (not shown), and the rotation locking device installs the laser head through the housing 10. The U-shaped fixing frame 20 is provided with a hand screw 60 that can be fixed or separated from the housing 10, but the hand screw 60 is always kept on the U-shaped fixing frame 20 and does not separate. At the same time, the U-shaped fixing frame 20 is also provided with a graphite nylon gasket 30, a plug screw 40, and a self-locking nut 50 for fixing the U-shaped fixing frame 20 on the housing 10. By moving the hand screw 60 to different fixing holes on the housing 10, the U-shaped fixing frame 20 is rotated and the operating angle of the laser engraving machine is changed, so that the side of the cylindrical object can be processed.

[0045] It should be further explained that the U-shaped fixing frame 20 is also provided with mounting holes for mounting the U-shaped fixing frame 20 on the laser engraving machine.

[0046] At the same time, a laser head mounting structure is arranged inside the housing 10 for mounting the laser head.
