DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a turning device for marble processing, including a bottom plate 1. Two first sliding grooves 2 are opened at the top of the bottom plate 1. First sliding blocks 3 are slidably embedded in the inner walls of the two first sliding grooves 2. Tooth racks 4 are fixedly installed at the tops of the two first sliding blocks 3. First pushing blocks 5 are fixedly installed on one side of the outer walls of the two tooth racks 4. Hydraulic rods 6 are fixedly connected to one side of the outer walls of the two first pushing blocks 5. A second sliding groove 7 is opened at the top of the bottom plate 1. A second sliding block 8 is slidably embedded in the inner wall of the second sliding groove 7. Two groups of L-shaped plates 9 are fixedly installed at the top of the bottom plate 1. Arc-shaped grooves 10 are opened at the tops of the two groups of L-shaped plates 9. First bearings 11 are movably contacted with the inner walls of the two groups of arc-shaped grooves 10. A rotating shaft 12 is fixedly inserted between the interiors of the two groups of first bearings 11. Two gears 13 are fixedly sleeved on the outer surface of one group of rotating shafts 12. A connecting rod 14 is fixedly installed at the top of the second sliding block 8. A second pushing block 15 is fixedly installed on one side of the outer wall of the connecting rod 14. An electric push rod 16 is fixedly connected to one side of the outer wall of the second pushing block 15. Two fixing frames 17 are fixedly installed on the outer surface of the connecting rod 14, and the outer surfaces of the two fixing frames 17 movably penetrate through the interiors of the two groups of L-shaped plates 9. One group of mounting plates 18 is fixedly installed on one side of the outer walls of the two fixing frames 17. First cylinders 19 are fixedly installed at the tops of the two groups of mounting plates 18, and the telescopic ends of the two groups of first cylinders 19 movably penetrate through the interiors of the two groups of mounting plates 18. The telescopic ends of the two groups of first cylinders 19 are fixedly connected with arc-shaped clamping plates 20.

[0024] The effect achieved by the entire Embodiment 1 is that by starting the electric push rod 16, its telescopic end drives the connecting rod 14 to move left and right, thereby driving the two fixing brackets 17 to slide in the same direction. In this process, the two groups of arc-shaped clamping plates 20 are precisely positioned at specific positions of the two groups of arc-shaped grooves 10. One group of arc-shaped clamping plates 20 is located exactly in the center of the top of one group of arc-shaped grooves 10, and the other group of arc-shaped clamping plates 20 is offset to one side of the top of the other group of arc-shaped grooves 10. Subsequently, by starting a corresponding group of first cylinders 19, the telescopic ends of the group of first cylinders 19 synchronously push the group of arc-shaped clamping plates 20 downward to firmly fix the arc-shaped clamping surfaces of the group of arc-shaped clamping plates 20 to the group of first bearings 11, thereby realizing the two-way flipping mechanism of the marble with the two rotating shafts 12 as the axis, significantly improving the efficiency of the flipping operation. After the marble is firmly fixed on the top of the flipping plate 21, the staff operates the two hydraulic rods 6 to start synchronously. If a left flip is required, the piston rods of the two hydraulic rods 6 will extend synchronously, pushing the two racks 4 to move horizontally to the left. Since a high-precision meshing design is adopted between the tooth shapes of the racks 4 and the teeth of the two groups of gears 13, as the racks 4 move to the left, their left tooth surfaces establish a meshing relationship with the teeth of the left group of gears 13, ensuring the close cooperation and accurate transmission between the two, and then driving the group of gears 13 to rotate. The rotational power of the group of gears 13 is transmitted to the flipping plate 21 through the rotating shaft 12, prompting it to complete an accurate 180-degree rotation around the rotating shaft 12 to realize the left flip of the marble. And because two rotating shafts 12 are fixedly sleeved on the inner surface wall of the flipping plate 21, and gears 13 are fixedly sleeved on the outer surface walls of the two rotating shafts 12, this precise design ensures that after the flipping plate 21 completes the flipping action and returns to the initial position, although the direct meshing relationship between the gears 13 and the racks 4 is temporarily released, the gears 13 will not cause accidental displacement or misalignment due to factors such as inertia, vibration, or external impact force. This stability guarantees that in subsequent operations, when a group of racks 4 moves again in the direction of this group of gears 13, the gears 13 can quickly and accurately re-establish a meshing relationship with the racks 4 without additional calibration or adjustment.

[0025] Embodiment 2, as Figures 2 - 4 shown, a flipping plate 21 is fixedly sleeved between the outer surface walls of a group of rotating shafts 12. A third chute 22 is opened at the top of the flipping plate 21. Two sliding frames 23 are slidably embedded in the inner surface wall of the third chute 22. A bidirectional lead screw 24 is threadedly connected between the inner surface walls of the two sliding frames 23. A self-locking motor 25 is fixedly connected to one side of the outer wall of the bidirectional lead screw 24. Two second bearings 26 are fixedly sleeved on the outer surface wall of the bidirectional lead screw 24. Second cylinders 27 are fixedly installed on the tops of the two sliding frames 23. The telescopic ends of the two second cylinders 27 are both fixedly connected with pressing plates 28. Two placing frames 29 are fixedly installed on the top of the bottom plate 1.

[0026] The effect achieved by the entire Embodiment 2 is as follows: First, the marble is steadily placed at the central position on the top of the turning plate 21. Subsequently, the self-locking motor 25 is started, and the output end of the self-locking motor 25 drives the bidirectional lead screw 24 to rotate. Based on the precise control principle of screw drive, the two sliding brackets 23 gradually approach each other inside the third chute 22, realizing the preliminary clamping and positioning of the marble, ensuring its stability and accuracy in subsequent operations. At this time, two second cylinders 27 are started, and the telescopic ends of the two second cylinders 27 operate synchronously, pushing the two pressing plates 28 towards the surface of the marble. After the pressing plates 28 contact the surface of the marble, an appropriate amount of pressure is continuously applied, thereby realizing the further pressing and fixing of the marble. This process not only enhances the stability of the marble during the turning process but also ensures the safe progress of the turning operation, effectively preventing accidents such as sliding and falling of the marble during the turning process.

[0027] Working principle: After the device is powered on, first, the marble needs to be accurately and stably placed at the center of the top of the turning plate 21. Subsequently, the self-locking motor 25 is started, and its output end drives the bidirectional lead screw 24 to rotate. Since the two sides of the bidirectional lead screw 24 adopt opposite thread designs, and the outer wall of the bidirectional lead screw 24 is threadedly connected to the inner walls of the two slide carriages 23, and the two slide carriages 23 are located on both sides of the bidirectional lead screw 24, the rotational movement of the bidirectional lead screw 24 can be directly converted into the relative movement between the two slide carriages 23, prompting them to approach each other, thereby achieving the preliminary clamping and fixing of the marble. Next, the staff starts two second cylinders 27 simultaneously, and the telescopic ends of the two second cylinders 27 work together to drive the two pressing plates 28 to apply pressure steadily to the surface of the marble, further ensuring the stability and safety of the marble during the turning process. When the marble needs to be turned to the left, first, the electric push rod 16 is started, and its telescopic end pushes the connecting rod 14 to move leftward. The connecting rod 14 then drives the two fixing brackets 17 and the two groups of arc-shaped clamping plates 20 to move to the corresponding positions, ensuring that a group of arc-shaped clamping plates 20 on the left are accurately aligned and located at the top of a group of arc-shaped grooves 10 on the left, while a group of arc-shaped clamping plates 20 on the right remain on one side of the top of the right arc-shaped groove 10. Subsequently, a group of first cylinders 19 on the left are started, and the telescopic ends of this group of first cylinders 19 push the corresponding group of arc-shaped clamping plates 20 to move downward, thereby closely adhering to and fixing a group of first bearings 11 on the left. At this time, the staff operates the two hydraulic rods 6, so that the telescopic ends of the two hydraulic rods 6 synchronously drive the two racks 4 to move leftward. Since the tooth shapes of the two racks 4 are precisely matched with the tooth shapes of the two groups of gears 13, and the leftward movement of the two racks 4 will cause their tooth parts to be closely engaged with the tooth parts of the left group of gears 13, thereby driving this group of gears 13 to rotate clockwise, and then driving the left rotating shaft 12 and the turning plate 21 to perform a 180-degree rotational movement. This rotational action will drive the marble fixed on the top of the turning plate 21 to complete the left turn, and finally place the marble stably on the top of the placing rack 29 on the left. On the contrary, when the marble needs to be turned to the right, only the above operations need to be performed in reverse to achieve the right turn of the marble. In this way, the device can efficiently and accurately complete the turning operation of the marble, greatly improving the flexibility and efficiency of turning.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
