Detailed Implementation

[0023] 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.

[0024] like Figures 1 to 6 As shown, this utility model is a high-precision transmission and vibration reduction structure for a metal 3D printing device, including a main body 1. The main body 1 has a support leg 6 at its bottom for supporting the main body 1. A transmission assembly 2 is installed inside the main body 1 to drive the print head 4 to move precisely in the horizontal direction. Specifically, as shown... Figures 1 to 4 As shown, the transmission assembly 2 includes a precision gear transmission mechanism 201, which includes a driving gear 2011, a driven gear 2012, a gear shaft 2013, and a longitudinal threaded shaft 2015. The longitudinal threaded shaft 2015 is threadedly connected to a slide. The driving gear 2011 meshes with the driven gear 2012 to achieve vertical transmission. The driving gear 2011 and the driven gear 2012 are respectively fitted with mutually perpendicular gear shafts 2013 and transverse threaded shafts 2016. More specifically, the gear shaft 2013 of the driving gear 2011 is slidably and rotatably mounted on one end of the slide, such as... Figure 2 As shown, the drive gear 2011 is rotatably connected to one end of the slide table, and then the gear shaft 2013 of the drive gear 2011 forms a sliding key and is slidably connected to the drive gear 2011; the transverse threaded shaft 2016 is threadedly connected to the mounting body slidably connected to the slide table, and the mounting body is used to install the print head 4. The longitudinal threaded shaft 2015 and the transverse threaded shaft 2016 respectively realize the movement in the horizontal X-axis direction and Y-axis direction. The two cooperate to enable the precision gear transmission mechanism 201 to drive the print head 4 to move precisely in the horizontal direction.

[0025] like Figure 4 As shown, the carrier platform for printing parts moves in the height direction through a lead screw motor, etc., and can achieve three-dimensional movement in space by combining with the precision gear transmission mechanism 201 to realize printing.

[0026] It should be noted that the drive gear 2011 and the longitudinal threaded shaft 2015 are driven by different motors. The motors are located on the side of the main body 1 of the device, and the output shaft of the motor is connected to the gear shaft 2013 of the drive gear 2011. The output shaft of the other motor is connected to the longitudinal threaded shaft 2015 to drive the print head 4 to move precisely in the horizontal direction.

[0027] To improve transmission accuracy and reduce friction and wear, the precision gear transmission mechanism 201 also includes a gearbox 2014. The driving gear 2011 and the driven gear 2012 are both disposed in the gearbox 2014. The gearbox 2014 is provided with lubricating oil to lubricate the driving gear 2011 and the driven gear 2012, thereby reducing friction and wear and ensuring transmission accuracy. By adopting the precision gear transmission mechanism 201, precise control of the print head 4 can be achieved, improving printing accuracy and printing quality.

[0028] Further optimizations include eliminating vibrations generated during printer operation, such as... Figures 4 to 6 As shown, an adaptive vibration damping platform 3 is provided at the bottom of the main body 1 of the equipment. The adaptive vibration damping platform 3 is used to reduce the vibration and noise of the equipment during operation and improve the stability of the equipment. Specifically, the adaptive vibration damping platform 3 includes a vibration damping base 301, a vibration damping spring 302, a vibration damping slider 303, and an adaptive adjustment mechanism 304. The top of the vibration damping base 301 is fixedly connected to the bottom of the main body 1 of the equipment, and a vibration damping cavity 3011 is provided at the bottom of the vibration damping base 301. The vibration damping spring 302 is disposed in the vibration damping cavity 3011, and the vibration damping slider 303 is slidably disposed in the vibration damping cavity 3011. The two ends of the vibration damping spring 302 are respectively connected to the bottom of the vibration damping cavity 3011 and the bottom of the vibration damping slider 303. When the equipment vibrates during operation, the vibration damping spring 302 can absorb and dissipate the vibration energy, reducing the vibration amplitude of the equipment.

[0029] To improve the shock absorption effect, specifically, such as Figure 5 As shown, guide strips 3031 are provided on both sides of the damping slider 303, and guide grooves 3012 that cooperate with the guide strips 3031 are provided on both sides of the damping cavity 3011. The damping slider 303 is slidably disposed in the guide grooves 3012 of the damping cavity 3011 through the guide strips 3031 on both sides. This design not only ensures the stability of the damping slider 303 during the damping process and prevents it from deviating, but also improves the overall rigidity and durability of the damping structure. The tight cooperation between the guide strips 3031 and the guide grooves 3012 effectively restricts the lateral movement of the damping slider 303, so that it can only perform vertical damping movement under the action of the damping spring 302.

[0030] Furthermore, the adaptive adjustment mechanism 304 enables the shock absorption structure to adaptively adjust according to the actual working state of the equipment; specifically, as shown in... Figure 5As shown, the adaptive adjustment mechanism 304 includes an adjustment rod 3041, an adjustment spring 3042, and an adjustment seat 3043. The top end of the adjustment rod 3041 is connected to the bottom of the damping slider 303, and its bottom end passes through the bottom of the damping cavity 3011 and extends to the outside of the device. Furthermore, the adjustment seat 3043 is threaded to the bottom end of the adjustment rod 3041, and the adjustment spring 3042 is fitted on the adjustment rod 3041 with its two ends connected to the bottom of the damping cavity 3011 and the top of the adjustment seat 3043, respectively. This design allows the adjustment seat 3043 to move up and down spirally within a certain range, thereby achieving fine adjustment of the damping effect.

[0031] The bottom of the adjustment seat 3043 is provided with an anti-slip pad 3044, which is made of a high-friction material. When the anti-slip pad 3044 is set to contact the bottom surface, it can increase the friction with the ground and effectively prevent the equipment from sliding due to vibration during the printing process. This not only improves the stability of the equipment, but also ensures the continuity and accuracy of the printing process.

[0032] By rotating the adjusting seat 3043, the compression of the adjusting spring 3042 can be adjusted, thereby achieving precise control of the shock absorption effect. This design allows users to flexibly adjust the performance of the shock absorption structure according to the actual working environment of the equipment and printing needs, so as to achieve the best shock absorption effect.

[0033] Of course, in order to improve the intelligence level of this utility model and facilitate the operation of the operator, such as Figure 6 As shown, a control panel 5 is provided on the side of the main body 1 of the equipment, which provides users with an intuitive operating interface. The control panel 5 is equipped with a display screen and operation buttons. Of course, the display screen can be replaced by a touch screen to facilitate operator interaction. Users can monitor the operating status and printing progress of the equipment in real time through the display screen, and control and adjust the equipment using the operation buttons. The control panel 5 is connected to the internal circuit of the main body 1 of the equipment through wires to ensure accurate signal transmission and timely execution of instructions.

[0034] In summary, this utility model provides a high-precision transmission and vibration reduction structure for metal 3D printing equipment. This structure effectively improves the printing accuracy and stability of the equipment by adopting a precision gear transmission mechanism and an adaptive vibration reduction platform. At the same time, this structure also has the advantages of simple structure, convenient operation, and easy maintenance, and is suitable for the manufacturing and application of various metal 3D printing equipment.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
