The overall structure of the adsorption plate is only suitable for larger marbles and often cannot be flexibly adjusted according to the specific shape and size of the marble. This can easily lead to local stress concentration during the adsorption process, increasing the risk of marble breakage. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figure 1-5 As shown, this utility model provides a gantry machine tool for marble cutting, including a machine base 1 and a cutting mechanism 2. A gantry mechanism 3 connected to the cutting mechanism 2 is provided on the machine base 1. The gantry mechanism 3 drives the cutting mechanism 2 to move horizontally, vertically and vertically. The gantry mechanism 3 is a mechanical structure used in commonly used CNC machine tools and can realize three-dimensional adjustment.

[0027] The inner side of the machine base 1 is fixedly connected to a support plate 4 arranged in a linear array. The machine base 1 is fixedly connected to an adsorption mechanism and an adjustment mechanism located below the support plate 4. The adsorption mechanism includes an adsorption plate 5 and an air pump 6. The air pump 6 is fixedly installed on the machine base 1. The adsorption plate 5 is engaged between multiple support plates 4. The air pump 6 enables the adsorption plate 5 to form a negative pressure to adsorb the marble. The adsorption plate 5 can be moved along the length of the support plate 4 through the adjustment mechanism.

[0028] In this embodiment, the adsorption plate 5 includes a central box 51 located below the support plate 4. The top of the central box 51 is connected to a plurality of adsorption boxes 52 arranged in a linear array. The top of the adsorption box 52 is provided with adsorption holes 53.

[0029] Specifically, the air pump 6 forms a negative pressure through the adsorption holes 53 of the centralized box 51 and the adsorption box 52 to adsorb the bottom surface of the marble. The multiple adsorption boxes 52 disperse the negative pressure to avoid marble fracture caused by local stress concentration.

[0030] In this embodiment, the adsorption hole 53 is a tapered hole, and the aperture of the adsorption hole 53 gradually increases from the direction of the adsorption box 52 to the centralized box 51.

[0031] Specifically, the air flow enters the adsorption hole 53 from the marble surface through the sponge layer 54 and the avoidance groove 55. The flow rate surges at the small aperture of the inlet for acceleration. The air flow expands in the adsorption hole 53, and the flow rate decreases, forming a stable negative pressure gradient, significantly improving the stability and energy efficiency of adsorption.

[0032] In this embodiment, a sponge layer 54 is fixedly connected to the top of the adsorption box 52. An avoidance groove 55 matching the adsorption hole 53 is formed on the sponge layer 54. The upper surface position of the adsorption box 52 is lower than the upper surface position of the support plate 4, and the upper surface position of the sponge layer 54 is higher than the upper surface of the support plate 4.

[0033] Specifically, the sponge layer 54 covers the top of the adsorption box 52, the avoidance groove 55 is aligned with the adsorption hole 53, the sponge layer 54 is higher than the surface of the support plate 4, and it fits the bottom surface of the marble after being pressed. The soft sponge avoids hard contact from damaging the marble surface and increases friction to prevent the marble from displacement.

[0034] In this embodiment, the cross-section of the support plate 4 is "convex" shaped, the gap between adjacent support plates 4 is an inverted "convex" shape, the shape of the adsorption box 52 is consistent with the shape of the gap between the two support plates 4, and the adsorption box 52 is slidably arranged between the two support plates 4.

[0035] Specifically, the cross-section of the support plate 4 is "convex" shaped, the shape of the adsorption box 52 is adapted to the gap between the two support plates 4, and only allows the adsorption box 52 to slide along the length direction of the support plate 4, restricting lateral displacement and avoiding deviation caused by cutting vibration.

[0036] In this embodiment, the adjusting mechanism includes a motor 7 and a screw rod 8. The screw rod ⑧ is rotatably arranged on the machine table 1. The motor 7 is fixedly installed on the machine table 1 and drives the screw rod 8 to rotate. A moving seat 9 is threadedly connected to the screw rod ⑧, and the moving seat 9 is fixedly connected to the lower side of the centralized box 51; the output shaft of the motor 7 is fixedly connected with a worm 10, a worm gear 11 is fixedly sleeved on the screw rod 8, the worm gear 11 meshes with the worm 1o, the transmission ratio of the worm 10 and the worm gear 11 is 40:1, and the lead of the screw rod 8 is 5mm.

[0037] Specifically, motor 7 drives worm gear 10, which in turn drives screw 8 to rotate in conjunction with worm wheel 11. Screw 8 pushes moving seat 9, which in turn drives adsorption plate 5 to move as a whole. The self-locking characteristics of worm gear 10 and worm wheel 11 prevent the load from driving in reverse and ensure position locking. The transmission and lead coordination achieve high-precision adjustment.

[0038] In this embodiment, a clearance pipe 12 is installed on the side of the central box 51, and a corrugated pipe 13 is installed between the end of the clearance pipe 12 away from the central box 51 and the air pump 6.

[0039] Specifically, the avoidance tube 12 can avoid the screw 8, preventing the corrugated tube 13 from getting entangled with the screw 8. The corrugated tube 13 moves and extends with the adsorption plate 5.

[0040] How to use and how to work this device:

[0041] When the device is in use, the motor 7 drives the worm 10 to rotate and cooperates with the worm wheel 11. The worm wheel 11 drives the screw 8 to rotate. The screw 8 pushes the moving seat 9 through the thread transmission, driving the adsorption plate 5 to translate along the length of the support plate 4. The self-locking characteristics of the worm 10 and worm wheel 11 prevent the cutting reaction force from causing position displacement, and can move the adsorption plate 5 to the desired position.

[0042] Subsequently, the marble is placed on the support plate 4, with the marble pressing on the sponge pad. The air pump 6 is started and draws air through the corrugated pipe 13 and the clearance pipe 12 to the conical adsorption holes 53 of the collection box 51 and the adsorption box 52, forming a negative pressure. After being pressed, the sponge layer 54 tightly adheres to the bottom surface of the marble, filling the surface unevenness and increasing friction. Multiple adsorption boxes 52 disperse the adsorption force, evenly fix the marble, avoid local stress concentration, and adsorb the marble to prevent it from sliding.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
