Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, specifically to a rotatable and adjustable fixing device for granite processing. Background Technology

[0002] Traditional granite processing techniques mainly include steps such as quarrying, cutting, grinding, and polishing. Quarrying involves first collecting raw granite blocks from the mine to ensure their quality and integrity. Cutting uses specialized equipment and tools, such as diamond saw blades, to precisely cut the blocks into the desired size and shape. Grinding removes burrs and uneven areas from the cut blocks, making them smoother. Polishing further polishes the surface of the stone, giving it a brighter, smoother, and more textured appearance.

[0003] Traditional fixing devices often use mechanical fixing methods such as bolts and clamps. However, the fixing effect is not ideal for granite of different sizes. They are prone to shaking or displacement during processing, which affects the processing accuracy. In the stone processing process, it is often necessary to cut or grind the stone at different angles. However, traditional fixing devices often lack flexible angle adjustment functions, making it difficult for processors to adjust the processing angle of the stone according to actual needs, thus limiting processing efficiency and flexibility. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotatable and adjustable fixing device for granite processing. This solves the technical problems of difficulty in effectively fixing granite during processing and inconvenient angle adjustment. It utilizes the combined action of a vacuum suction cup and a cylinder to achieve a firm fixation of the granite. By adjusting the rotating part, the device can easily adjust the processing angle of the granite. Through the effective fixing and flexible adjustment functions of this device, processors can process granite more precisely, avoiding processing errors caused by stone movement or shaking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotatable and adjustable fixing device for granite processing, comprising a supporting base block, an adjusting rotating part, and a stone fixing clamping part. Supporting legs are fixedly installed equidistantly on the bottom outer wall of the supporting base block, and supporting pads are fixedly installed on the bottom outer wall of the supporting legs. The adjusting rotating part is located on the top of the supporting base block, and the stone fixing clamping part is located on the top of the adjusting rotating part.

[0006] Preferably, the adjusting rotation part specifically includes: a mounting groove formed on the top outer wall of the support base block; a drive motor disposed inside the mounting groove; a rotation adjustment plate disposed on the top of the support base block; and a rotation limiting block circumferentially fixedly installed on the top outer wall of the support base block.

[0007] A rotation limit block is installed, and the rotation limit groove on the rotation limit block slides in conjunction with the rotating circular plate, ensuring the stability and accuracy of the rotation adjustment plate during rotation. This avoids processing errors caused by excessive rotation or deflection. In conjunction with the mounting groove, drive motor, rotation adjustment plate and other components, the 360-degree rotation adjustment function of the stone fixing clamp is realized, which greatly improves the flexibility and convenience of stone processing.

[0008] Preferably, the drive motor is fixedly installed on the inner wall of the mounting groove, the output end of the drive motor is fixedly connected to a rotating pad, and a rotating circular plate is fixedly installed on the top outer wall of the rotating pad.

[0009] Preferably, each of the rotating limiting blocks is provided with a rotating limiting groove, the rotating circular plate is slidably installed inside the rotating limiting groove, and a rotating connecting block is fixedly installed on the top outer wall of the rotating circular plate. The top outer wall of the rotating connecting block is fixedly connected to the bottom outer wall of the rotating adjusting plate.

[0010] Preferably, the stone fixing clamping part specifically includes: a support rod, which is circumferentially and equidistantly fixed on the top outer wall of the rotating adjustment plate; a fixed support plate, which is fixedly installed on the top of the support rod; and an air pump, which is fixedly installed on the top outer wall of the rotating adjustment plate.

[0011] An air pump is installed, which, in conjunction with a vacuum suction cup, allows for a firm gripping and fixation of the stone. The air pump generates negative pressure, which is transmitted to the vacuum suction cup through connecting air pipes, connecting bends, and connecting blocks. This ensures the vacuum suction cup adheres tightly to and firmly grips the stone, guaranteeing its stability during processing.

[0012] Preferably, the top outer wall of the fixed support plate has equidistant mounting openings, and support pads are fixedly mounted equidistantly on the top outer wall of the fixed support plate. A fixing plate is fixedly mounted on the bottom outer wall of the fixed support plate. A vacuum suction cup is fixedly mounted on the inner wall of the mounting openings. A circular opening is provided on the fixing plate, and the fixing plate is fixedly fitted onto the outer wall of the vacuum suction cup through the circular opening. A connecting block is fixedly mounted on the bottom outer wall of the fixing plate.

[0013] Support pads are installed, with the height of the support pads slightly lower than the vacuum suction cup mentioned later, to prevent the vacuum suction cup from being crushed. When the stone is placed on the fixing device, the vacuum suction cup can make contact with the bottom surface of the stone first. Because granite is hard and heavy, vibrations during processing and impacts during handling may damage the components below. The support pads can effectively distribute the pressure and prevent the vacuum suction cup from deforming, wearing or even breaking due to excessive pressure.

[0014] Preferably, the outer wall of the connecting block is provided with connecting bends at equal intervals around its circumference. The other end of the connecting bends is connected to the bottom outer wall of the vacuum suction cup. The bottom outer wall of the connecting block is provided with a connector. The bottom outer wall of the connector is provided with a connecting air pipe. The other end of the connecting air pipe is connected to the output end of the air pump. The top outer wall of the fixed support plate is fixedly installed with trapezoidal support blocks at equal intervals around its circumference. The top outer wall of each trapezoidal support block is fixedly installed with an L-shaped fixing bracket.

[0015] Preferably, a cylinder fixing bracket is fixedly installed on one outer wall of the L-shaped fixing bracket, and a cylinder is fixedly installed inside the cylinder fixing bracket. The telescopic end of the cylinder movably passes through one outer wall of the L-shaped fixing bracket and extends to the other side of the L-shaped fixing bracket. A clamping push plate is fixedly connected to the telescopic end of the cylinder. Clamping pads are fixedly installed at equal intervals on the outer wall of the clamping push plate. Fixing ear plates are fixedly installed on both outer walls of the L-shaped fixing bracket. Sliding holes are opened on the fixing ear plates. A sliding rod is slidably connected inside the sliding holes. One end of the sliding rod is fixedly connected to the outer wall of the clamping push plate, and the other end of the sliding rod is fixedly connected to a limiting plate. The limiting plate is located on one side of the fixing ear plate.

[0016] A cylinder is installed as a driving element, which can provide stable and controllable thrust. In the stone fixing and clamping part, the telescopic end of the cylinder is connected to the clamping push plate. Through the telescopic movement of the cylinder, the clamping push plate can clamp the stone tightly, ensuring the stability and safety of the stone during the processing.

[0017] This utility model provides a rotatable and adjustable fixing device for granite processing. It has the following advantages:

[0018] (1) This utility model drives the rotating circular plate and the rotating adjustment plate to rotate by a drive motor, so that the stone can be easily adjusted at multiple angles, which greatly improves the flexibility and adaptability of processing. The combined use of the rotating limit block and the rotating limit slide can limit the rotation range of the rotating circular plate and prevent the stone from shifting or shaking during processing, thereby improving the processing accuracy. The stable connection of the support base block, the rotating adjustment plate and the fixed support plate, as well as the limiting effect of the rotating limit block and the rotating limit slide, together ensure the stability of the device during processing.

[0019] (2) This utility model can firmly clamp the stone through components such as vacuum suction cup and cylinder, preventing it from shaking or shifting during processing. This stability is crucial for ensuring processing accuracy and stone integrity. Especially when performing fine processing, by adjusting the suction force of the vacuum suction cup and the extension length of the cylinder, it can adapt to various types of stone, improving the versatility and applicability of the device. This eliminates the need for workers to spend a lot of time manually adjusting the position and stability of the stone, thereby improving production efficiency. Attached Figure Description

[0025] 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.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1:

[0028] A preferred embodiment of the rotatable and adjustable fixing device for granite processing provided by this utility model is, for example... Figure 1-4 As shown: A rotatable and adjustable fixing device for granite processing includes a supporting base 1, an adjusting rotating part 3, and a stone fixing clamping part 4. Supporting legs 2 are fixedly installed equidistantly on the bottom outer wall of the supporting base 1, and supporting pads are fixedly installed on the bottom outer wall of the supporting legs 2. The adjusting rotating part 3 is located on the top of the supporting base 1, and the stone fixing clamping part 4 is located on the top of the adjusting rotating part 3.

[0029] The adjusting rotating part 3 specifically includes: a mounting groove 311, which is formed on the top outer wall of the support base block 1; a drive motor 312, which is set inside the mounting groove 311; a rotating adjusting plate 318, which is set on the top of the support base block 1; and a rotating limiting block 314, which is circumferentially fixedly installed on the top outer wall of the support base block 1.

[0030] The drive motor 312 is fixedly installed on the inner wall of the mounting groove 311. The output end of the drive motor 312 is fixedly connected to the rotating pad 313. The top outer wall of the rotating pad 313 is fixedly installed with the rotating circular plate 316.

[0032] In this embodiment, the drive motor 312 is started, which drives the rotating pad 313 to rotate. The rotating circular plate 316 on the rotating pad 313 slides smoothly within the rotating limiting groove 315 of the rotating limiting block 314. Then, through the rotating connecting block 317, the rotating adjusting plate 318 and the stone fixed above it rotate together. The operator can precisely control the rotation angle of the drive motor 312 to adjust the surface of the stone to be processed to the optimal processing position, meet the processing requirements of multiple angles and all directions, prevent the stone from shifting or shaking during processing, thereby improving processing accuracy. The stable connection of components such as the support base block, rotating adjusting plate and fixed support plate, as well as the limiting function of the rotating limiting block and rotating limiting groove, together ensure the stability of the device during processing.

[0033] Example 2:

[0034] Based on Embodiment 1, a preferred embodiment of the rotatable and adjustable fixing device for granite processing provided by this utility model is, for example... Figure 1-4As shown: The stone fixing clamping part 4 specifically includes: a support rod 411, which is circumferentially and equidistantly fixed on the top outer wall of the rotating adjustment plate 318; a fixed support plate 412, which is fixedly installed on the top of the support rod 411; and an air pump 414, which is fixedly installed on the top outer wall of the rotating adjustment plate 318.

[0035] The top outer wall of the fixed support plate 412 is provided with equidistant mounting openings. Support pads 413 are fixedly mounted on the top outer wall of the fixed support plate 412 at equidistant intervals. The bottom outer wall of the fixed support plate 412 is fixedly mounted with a fixing plate 418. A vacuum suction cup 419 is fixedly mounted on the inner wall of the mounting opening. The fixing plate 418 is provided with a circular opening. The fixing plate 418 is fixedly fitted onto the outer wall of the vacuum suction cup 419 through the circular opening. A connecting block 416 is fixedly mounted on the bottom outer wall of the fixing plate 418.

[0036] The outer wall of the connecting block 416 is circumferentially connected with connecting bends 417, the other end of which is connected to the bottom outer wall of the vacuum suction cup 419. The bottom outer wall of the connecting block 416 is connected with a connector, the bottom outer wall of which is connected with a connecting air pipe 415, the other end of which is connected to the output end of the air pump 414. The top outer wall of the fixed support plate 412 is circumferentially fixed with trapezoidal support blocks 4111, and the top outer wall of each trapezoidal support block 4111 is fixed with an L-shaped fixing bracket 4112.

[0037] A cylinder mounting bracket is fixedly installed on one outer wall of the L-shaped mounting bracket 4112. A cylinder 4113 is fixedly installed inside the cylinder mounting bracket. The telescopic end of the cylinder 4113 moves through one outer wall of the L-shaped mounting bracket 4112 and extends to the other side of the L-shaped mounting bracket 4112. A clamping push plate 4114 is fixedly connected to the telescopic end of the cylinder 4113. Clamping pads 4117 are fixedly installed at equal intervals on the outer wall of the clamping push plate 4114. Fixing ear plates 4115 are fixedly installed on both outer walls of the L-shaped mounting bracket 4112. A sliding hole is opened on the fixing ear plate 4115. A sliding rod 4116 is slidably connected inside the sliding hole. One end of the sliding rod 4116 is fixedly connected to the outer wall of the clamping push plate 4114. A limit plate is fixedly connected to the other end of the sliding rod 4116. The limit plate is located on one side of the fixing ear plate 4115.

[0038] In this embodiment, the cylinder 4113 is activated, and the telescopic end of the cylinder 4113 pushes the clamping push plate 4114 to move towards the side of the stone. The clamping pad 4117 on the clamping push plate 4114 gradually approaches the stone until it is tightly attached to the side of the stone, thus accurately clamping the stone from multiple directions. During this process, the slide rod 4116 slides synchronously in the sliding hole of the fixed ear plate 4115, which plays a role in guiding and stabilizing the clamping push plate 4114, ensuring a smooth clamping process and firmly fixing the stone in the vertical direction. By adjusting the suction force of the vacuum suction cup and the telescopic length of the cylinder, it can adapt to various types of stone, improving the versatility and applicability of the device. This eliminates the need for workers to spend a lot of time manually adjusting the position and stability of the stone, thereby improving production efficiency.

[0039] Working principle: When using:

[0040] Step 1: First, check the entire fixing device to ensure that the support legs 2 at the bottom of the support base block 1 and the support pads on them are stable and undamaged, providing a solid foundation for subsequent load bearing. Check the adjusting rotating part 3 to confirm that the drive motor 312 in the installation groove 311 is firmly installed, the rotation limit block 314 and the rotation limit slide 315 on it are free of foreign objects, and the rotating adjusting plate 318 can rotate freely. At the same time, check the stone fixing clamping part 4 to ensure that the support rod 411, the fixed support plate 412, the air pump 414 and other components are connected normally, the vacuum suction cup 419 is undamaged, and the cylinder 4113 extends and retracts freely.

[0041] Step 2: Move the granite stone to be processed to the top of the fixing device and slowly lower it so that the bottom of the stone rests on the support pad 413 on the top of the fixed support plate 412. At this time, the support pad 413 initially supports the weight of the stone, preventing the stone from directly impacting the vacuum suction cup 419, and at the same time ensuring that the stone is roughly in the center of the fixed support plate 412 for subsequent precise fixing.

[0042] Step 3: Start the air pump 414. The air pump 414 extracts the air from the vacuum suction cup 419 through the connecting air pipe 415, the connecting block 416 and the connecting elbow 417, so that a negative pressure environment is formed inside the vacuum suction cup 419. Under the action of the external atmospheric pressure, the vacuum suction cup 419 tightly adheres to the bottom surface of the stone, achieving initial stabilization and preventing the stone from moving easily in the horizontal direction.

[0043] Step 4: Activate cylinder 4113. The telescopic end of cylinder 4113 pushes the clamping push plate 4114 to move towards the side of the stone. The clamping pad 4117 on the clamping push plate 4114 gradually approaches the stone until it is tightly attached to the side of the stone, accurately clamping the stone from multiple directions. During this process, the slide rod 4116 slides synchronously in the sliding hole of the fixed ear plate 4115, which plays the role of guiding and stabilizing the clamping push plate 4114, ensuring that the clamping process is stable and that the stone is also firmly fixed in the vertical direction.

[0044] Step 5: According to the processing requirements, start the drive motor 312. The drive motor 312 drives the rotating pad 313 to rotate. The rotating circular plate 316 on the rotating pad 313 slides smoothly in the rotating limiting groove 315 of the rotating limiting block 314. Then, through the rotating connecting block 317, it drives the rotating adjusting plate 318 and the stone fixed above it to rotate together. The operator can accurately control the rotation angle of the drive motor 312 to adjust the stone surface to be processed to the best processing position to meet the processing requirements of multiple angles and all directions.

[0045] Step Six: After the stone processing is completed, first turn off the air pump 414, slowly inject air into the vacuum suction cup 419 to balance the pressure difference between the inside and outside, so that the vacuum suction cup 419 releases its adsorption on the stone. Then, control the cylinder 4113 to retract, drive the clamping push plate 4114 away from the stone, release the clamping on the stone, and finally, safely remove the processed stone from the fixing device to prepare for the next round of processing.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
