For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0025] like Figure 1-5 As shown, the positioning mechanism of a table tennis racket marking device proposed in the present invention includes a workbench 1, a marking machine 2 is provided on the top of the workbench 1, a controller 4 is provided on the top of the workbench 1, bases 5 are provided at the four corners of the bottom of the top of the workbench 1, and a positioning structure 3 is provided on the top of the workbench 1.

[0026] In the present invention, the table tennis racket can be fixed by the positioning structure 3, the table tennis racket can be marked by the marking machine 2 and the controller 4, and the workbench 1 can be stably supported by the base 5.

[0027] In an optional embodiment, the positioning structure 3 includes a placement plate 31, a fixed box 32, a double-headed threaded rod 33, two movable plates 34, two groups of limiting components 35, two groups of abutment components 36 and a drive component 37. The placement plate 31 is arranged at the top of the workbench 1, the fixed box 32 is arranged at the bottom of the workbench 1, the double-headed threaded rod 33 is rotatably connected between the left and right side walls of the inner cavity of the fixed box 32, the two movable plates 34 are respectively threadedly connected to the two ends of the double-headed threaded rod 33 with opposite thread directions, the two groups of abutment components 36 are respectively arranged at the bottom of the two movable plates 34, the two groups of abutment components 36 are respectively arranged at the top of the two movable plates 34, the drive component 37 is arranged inside the fixed box 32, and the output end of the drive component 37 is connected to the double-headed threaded rod 33.

[0028] It should be noted that when it is necessary to mark the table tennis racket, the table tennis racket is first placed between the two sets of abutment components 36, and then the double-headed threaded rod 33 is driven to rotate by the driving component 37. Under the action of the two sets of limit components 35, the two movable plates 34 will not rotate. When the double-headed threaded rod 33 rotates, under the action of the thread thrust, the double-headed threaded rod 33 will drive the two movable plates 34 to move to the opposite side or the opposite side, and the two movable plates 34 will respectively drive the two sets of abutment components 36 to move to the opposite side or the opposite side. When the two sets of abutment components 36 abut against the outside of the table tennis racket, the table tennis racket can be abutted to ensure the stability of the table tennis racket during marking.

[0029] In an optional embodiment, the drive assembly 37 includes a servo motor 371, a rotating shaft 372 and an engagement module 373. The servo motor 371 is arranged at the bottom of the fixed box 32, the rotating shaft 372 is arranged on the output shaft of the servo motor 371, the other end of the rotating shaft 372 extends to the interior of the fixed box 32, and the engagement module 373 is arranged at the top of the rotating shaft 372.

[0030] It should be noted that when the servo motor 371 is started, the output shaft of the servo motor 371 drives the rotating shaft 372 to rotate, and the rotating shaft 372 drives the engaging module 373 to move, thereby driving the double-threaded rod 33 to rotate.

[0031] In an optional embodiment, the meshing module 373 includes a driving bevel gear 3731 and a driven bevel gear 3732. The driving bevel gear 3731 is arranged at the top of the rotating shaft 372, and the driven bevel gear 3732 is arranged on the outside of the double-headed threaded rod 33. The driving bevel gear 3731 and the driven bevel gear 3732 are meshed.

[0032] It should be noted that when the rotating shaft 372 rotates, the rotating shaft 372 drives the driving bevel gear 3731 to rotate, the driving bevel gear 3731 drives the driven bevel gear 3732 meshing therewith to rotate, and the driven bevel gear 3732 drives the double-headed threaded rod 33 to rotate.

[0033] In an optional embodiment, the limiting assembly 35 includes a limiting block 351 and a limiting groove 352. The two limiting blocks 351 are respectively arranged at the bottom of the two movable plates 34, and the two limiting grooves 352 are opened on the inner bottom wall of the fixed box 32. The two limiting blocks 351 are respectively slidably connected to the inside of the two limiting grooves 352.

[0034] It should be noted that the movable plate 34 can be limited by the limiting block 351 and the limiting groove 352. While preventing the movable plate 34 from rotating, the movement trajectory of the movable plate 34 can also be limited to avoid the movable plate 34 and the engagement module 373 from being limited.

[0035] In an optional embodiment, the abutment assembly 36 includes a mounting plate 361 and an abutment arc plate 362. The two mounting plates 361 are respectively arranged on the top of the two movable plates 34. The two mounting plates 361 extend to the top of the placement plate 31. The two abutment arc plates 362 are respectively arranged on the opposite sides of the two mounting plates 361.

[0036] It should be noted that when the two movable plates 34 move toward one side or the other side, the two movable plates 34 will respectively drive the two mounting plates 361 to move toward one side or the other side, and the two mounting plates 361 will respectively drive the two abutting arc plates 362 to move toward one side or the other side. When the two abutting arc plates 362 move toward one side and both abut against the outside of the table tennis racket, the table tennis racket can be fixed to ensure the stability of the table tennis racket during marking. After the marking is completed, the two abutting arc plates 362 are moved toward one side or the other. When the two abutting arc plates 362 are separated from the table tennis racket, the table tennis racket can be removed.

[0037] In an optional embodiment, two sliding holes are opened on the top of the placement plate 31 and penetrate into the interior of the fixed box 32, and the front and back sides of the mounting plate 361 are slidably connected to the front and rear side walls of the inner cavity of the sliding holes respectively.

[0038] It should be noted that the two sliding holes can respectively ensure the stability of the movement of the two mounting plates 361.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
