[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] like Figures 1 to 3 The multi-head engraving machine 3 shown mainly includes a cooperating engraving base 31, a gantry frame assembly 32, a gantry transmission assembly 33, and an engraving assembly 34.

[0021] The carving base 31 is mainly used to support the gantry frame assembly 32, gantry transmission assembly 33 and carving assembly 34. It includes a bottom support frame 311 set on the ground, a carving carrier plate 312 installed on the bottom support frame 311 (i.e. the carving carrier plate 312 is installed on the top of the bottom support frame 311), and an extension plate 313 installed on the side of the bottom support frame 311 and extending to the outside of the carving carrier plate 312. The carving carrier plate 312 has multiple parallel and spaced mounting grooves 3121 (at this time, the extension direction of the extension plate 313 is perpendicular to the extension direction of the mounting grooves 3121). In this way, multiple carbon fiber square tubes can be installed side by side on the carving carrier plate 312 by cooperating with multiple bolt pairs and other conventional fasteners with the multiple mounting grooves 3121.

[0022] The gantry assembly 32 is slidably mounted on the engraving base 31 via the gantry drive assembly 33. The engraving assembly 34 is slidably mounted on the gantry assembly 32 and includes a vertical base plate 341, a vertical adapter plate 345 slidably mounted on the vertical base plate 341, a horizontal base plate 346 mounted on the vertical adapter plate 345 and arranged horizontally, and a plurality of engraving heads 349 mounted on the horizontal base plate 346 and spaced apart (the plurality of engraving heads 349 are independent of each other and can work independently, using existing conventional methods; or they can be connected to the same industrial computer in a conventional manner for collaborative control).

[0023] In this embodiment, the engraving assembly 34 further includes multiple vertical slide rails 343 (usually two) mounted on the surface of the vertical base plate 341 and spaced apart, multiple sets of vertical sliders 344 mounted on the vertical adapter plate 345 and cooperating with the vertical slide rails 343 (each set of vertical sliders 344 has at least one vertical slider 344, but preferably two; the same applies below), a ball screw assembly 342 connected to the vertical adapter plate 345, and a first stepper motor 340 mounted at the end of the ball screw assembly 342 (the ball screw assembly 342 and the first stepper motor 340 constitute a ball screw module). When the first stepper motor 340 is working, it can drive the ball screw assembly 342 to rotate, thereby driving the vertical adapter plate 345 to rise and fall on the vertical slide rails 343 via the vertical sliders 344. The engraving assembly 34 also includes multiple first slide rail pads 3411 mounted on the surface of the vertical base plate 341 and spaced apart, and an engraving head carrier plate 347 mounted on the horizontal base plate 346. Vertical slide rails 343 are correspondingly mounted on the first slide rail pads 3411, and each engraving head 349 is mounted on the engraving head carrier plate 347 via an engraving head mounting base 348. The spacing between the engraving heads 349 can be adjusted by adjusting the mounting spacing of the engraving head mounting bases 348 on the engraving head carrier plate 347 to accommodate carbon fiber square tubes of different sizes, thereby enabling machining of the corresponding carbon fiber square tubes using the engraving heads 349.

[0024] In this embodiment, the gantry transmission assembly 33 includes a second slide rail pad 331 fixed to both sides of the bottom support frame 311 (the fixing is conventional, such as integral molding or fastener connection), a transverse slide rail 332 mounted on the second slide rail pad 331, a transverse slider 333 slidably mounted on the transverse slide rail 332, a first rack 337 mounted on the side of the second slide rail pad 331 and having a first serration 3371 on its bottom surface, a transmission carrier plate 334 mounted on the gantry frame assembly 32, a first drive wheel 336 rotatably mounted on the transmission carrier plate 334, a gantry moving motor 335 mounted on the transmission carrier plate 334 and connected to the first drive wheel 336 via a first transmission belt, and a first transmission helical gear connected to the first drive wheel 336 and meshing with the first rack 337 (the center of the first transmission helical gear is connected to the center of the first drive wheel 336 via a connecting shaft, and they rotate synchronously; the connection method adopts conventional methods, such as snap-fit ​​or pin-fit; the same applies below). The gantry frame assembly 32 includes a gantry side support plate 321 connected to the transverse slider 333, a gantry top beam 322 mounted on the gantry side support plate 321, multiple gantry transverse slide rails 323 mounted on the side of the gantry top beam 322 and spaced apart, and a second rack 325 mounted on the top surface of the gantry top beam 322 and provided with a second serration 3251. At this time, the transmission carrier plate 334 is mounted on the gantry side support plate 321. In this embodiment, the gantry frame assembly 32 further includes multiple sets of gantry sliders 324 slidably mounted on the gantry horizontal slide rail 323, a gantry upper plate 326 mounted on the engraving assembly 34 and extending horizontally (the gantry upper plate 326 and the vertical base plate 341 are connected in a conventional manner and are perpendicular to each other), a second drive wheel 328 rotatably mounted on the gantry upper plate 326, an engraving assembly moving motor 327 mounted on the gantry upper plate 326 and connected to the second drive wheel 328 via a second transmission belt, and a second transmission helical gear 329 connected to the second drive wheel 328 and meshing with the second rack 325.

[0025] When the gantry moving motor 335 is working, it can drive the gantry frame assembly 32 to move on the transverse slide rail 332; when the engraving assembly moving motor 327 is working, it can drive the engraving assembly 34 to move on the gantry transverse slide rail 323; thus ensuring that the engraving head 349 moves accurately to the part of the product to be processed. Through the cooperation of the above structures, the multi-head engraving machine with the above structure also has the advantages of high precision and good reliability.

[0026] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
