Description

Technical Field

[0001] This invention relates to the field of stone processing equipment technology, and more specifically to a clamping rotary platform for stone processing. Background Technology

[0002] With the development of architectural design, stone has long been one of the important raw materials for building, decoration, road and bridge construction. Stone vase columns, for example, are not only exquisitely carved, beautiful and durable, but also offer excellent protective properties. They are mainly used for protection in factories, garden squares, parking lots, commercial areas, flagpoles, bridges, and public places. However, in the processing of stone vase columns, each workstation needs to move the stone, disassembling it from one workstation to the next. This is especially true between the cutting and roughing workstations, where a single piece of stone is being cut... After processing, multiple strips of stone will be cut side by side and close together. There is not enough roughing space between two adjacent strips of stone. At this time, it is not possible to directly rough cut multiple strips of stone side by side. Usually, it is necessary to manually transfer the individual strips of stone so that they can be rough cut at the roughing station. However, this makes it difficult to achieve continuous production of stone vase columns, which will affect the overall production efficiency. In addition, the labor intensity of the operators transferring the stones is high, which will increase labor costs. Therefore, further improvement is needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a clamping rotary platform for stone processing that has a stable and reliable overall structure, is easy to operate, can realize continuous production, effectively ensures overall production efficiency, greatly reduces the labor intensity of operators, and helps to reduce overall labor costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a clamping rotary platform for stone processing, comprising a rotary drive base, a rotating disk disposed on the upper end of the rotary drive base, and a stone clamping assembly disposed on the upper end of the rotating disk. The rotary drive base is used to drive the rotating disk to rotate intermittently. There are six stone clamping assemblies, which are evenly arranged along the rotation direction of the rotating disk and correspond one-to-one with the loading station, cutting station, roughing station, fine cutting station, polishing station, and unloading station around the rotating disk. The stone clamping assembly includes multiple clamping mechanisms and a telescopic drive mechanism. The clamping mechanism is used to clamp the stone and is radially slidably connected to the rotating disk. The telescopic drive mechanism is used to drive the multiple clamping mechanisms to move closer to or further away from each other.

[0005] Furthermore, the clamping mechanism includes a support base, a first slide block, a second slide block, and a sliding drive assembly. The two ends of the support base are slidably connected to the rotating disk through the first sliding assembly. The first slide block and the second slide block are respectively located on the left and right sides of the upper end of the support base and are slidably connected to the support base through the second sliding assembly. The sliding drive assembly is located on the support base and is used to drive the first slide block and the second slide block to move synchronously in opposite directions. The first slide block is provided with a first support shaft, and a rotatable first clamping top block is installed at one end of the first support shaft. The second slide block is provided with a rotatable second support shaft, and a second clamping top block is fixedly installed at one end of the second support shaft. The second slide block is provided with a rotary drive assembly for driving the second support shaft to rotate.

[0006] Furthermore, the sliding drive assembly includes a sliding hydraulic cylinder and a tension spring. The two ends of the sliding hydraulic cylinder are fixedly connected to the first slide and the second slide, respectively. At least one tension spring is fixedly provided between the first slide and the second slide and the support seat.

[0007] Furthermore, the telescopic drive mechanism includes a telescopic hydraulic cylinder and an X-shaped telescopic frame. The support seats on the multiple clamping mechanisms are respectively hinged to multiple central hinge points on the X-shaped telescopic frame. The cylinder body of the telescopic hydraulic cylinder is fixedly installed on the rotating disk. The piston rod end of the telescopic hydraulic cylinder is fixedly connected to the innermost support seat, and the outermost support seat is fixedly installed.

[0008] Furthermore, the first support shaft is movably sleeved inside the fixed cylinder and slides in cooperation with the fixed cylinder. The fixed cylinder is fixedly installed on the upper end of the first slide block. A moving drive assembly for driving the first support shaft to move is provided on one side of the fixed cylinder. A guide groove is provided on the surface of the first support shaft along its axial direction. A guide block is provided on the fixed cylinder that is locked in the guide groove and adapted to the guide groove.

[0009] Furthermore, when the stone clamping assembly is in the cutting position, a first cutting gap is provided between the first slides on two adjacent clamping mechanisms, and a second cutting gap is provided between the second slides on two adjacent clamping mechanisms.

[0010] Furthermore, the rotating disk is fixedly provided with mounting plates for installing stone clamping assemblies. The number of mounting plates is consistent with the number of stone clamping assemblies and corresponds one-to-one. At least one support leg is fixedly installed on the suspended end of the mounting plate. Rotatable rollers are installed at the bottom of the support legs. The rollers abut against the inner ring guide rail and the two roll in cooperation. The ring guide rail is located on the outside of the rotating drive base.

[0011] Furthermore, the mounting plate has slots running through its upper and lower ends, and an annular water collection tank is located below the slots.

[0012] Furthermore, a limiting and fixing mechanism is provided between the innermost support and the mounting plate. The limiting and fixing mechanism includes a limiting plate, a first limiting pin, and a second limiting pin. The limiting plate is provided with limiting holes that are adapted to the first limiting pin and the second limiting pin. Limiting plates are fixedly installed at both ends of the innermost support. A first limiting hydraulic cylinder and a second limiting hydraulic cylinder are installed on the left and right sides of the lower end of the mounting plate. The piston rod end of the first limiting hydraulic cylinder is fixedly installed with a first limiting pin, and the piston rod end of the second limiting hydraulic cylinder is fixedly installed with a second limiting pin.

[0013] Furthermore, the rotary drive base includes a base body and an intermittent drive source. The rotating disk is rotatably mounted on the upper end of the base body via a slewing bearing. The intermittent drive source is located inside the base body and is used to drive the rotating disk to rotate intermittently.

[0014] As described above, the clamping rotary platform for stone processing provided by this invention has a stable and reliable overall structure, is easy to operate, and has the following beneficial effects: During processing, the stone to be processed is first loaded onto the stone clamping assembly at the loading station. Then, driven by the intermittent rotation of the rotary drive base, the stone to be processed can sequentially pass through the loading station, cutting station, roughing station, fine cutting station, polishing station, and unloading station. In particular, between the cutting station and the roughing station, multiple clamping mechanisms can be used to clamp and fix multiple cut strip stones separately. Then, through the telescopic drive... The mechanism can easily move multiple clamping mechanisms away from each other, thus separating multiple cut strips of stone. This directly creates sufficient roughing, fine cutting, and polishing space between adjacent strips of stone, facilitating the simultaneous roughing, fine cutting, and polishing of multiple strips of stone at the roughing, fine cutting, and polishing stations. In this way, the processing of stone vase columns can achieve continuous production, effectively ensuring overall production efficiency. There is no need for operators to transport and transfer stones between each station, greatly reducing the labor intensity of operators and helping to reduce overall labor costs.

Detailed Implementation

[0023] The present invention will be further described below through specific embodiments.

[0024] like Figures 1 to 7 As shown, the clamping rotary platform for stone processing of the present invention includes a rotary drive base 1, a rotating disk 2 disposed on the upper end of the rotary drive base 1, and a stone clamping assembly 3 disposed on the upper end of the rotating disk 2. The rotary drive base 1 is used to drive the rotating disk 2 to rotate intermittently. There are six stone clamping assemblies 3, which are evenly arranged along the rotation direction of the rotating disk 2 and correspond one-to-one with the loading station 91, cutting station 92, roughing station 93, fine cutting station 94, polishing station 95 and unloading station 96 around the rotating disk 2. The stone clamping assembly 3 includes multiple clamping mechanisms 4 and a telescopic drive mechanism 5. The clamping mechanism 4 is used to clamp the stone and is radially slidably connected to the rotating disk 2. The telescopic drive mechanism 5 is used to drive the multiple clamping mechanisms 4 to move closer to each other or further away from each other.

[0025] During processing, the stone to be processed is first loaded onto the stone clamping assembly 3 at loading station 91. Then, driven by the intermittent rotation of the rotary drive base 1, the stone to be processed sequentially passes through loading station 91, cutting station 92, roughing station 93, fine cutting station 94, polishing station 95, and unloading station 96. In particular, between cutting station 92 and roughing station 93, multiple clamping mechanisms 4 can be used to clamp and fix multiple cut strip stones separately. Then, the telescopic drive mechanism 5 can easily drive the multiple clamping mechanisms 4. By separating the cut stone strips, sufficient roughing, finishing, and polishing space is created between adjacent strips. This allows for simultaneous roughing, finishing, and polishing of multiple stone strips at roughing station 93, finishing station 94, and polishing station 95. As a result, continuous production of stone vase columns can be achieved, effectively ensuring overall production efficiency. There is no need for operators to move the stone between each station, greatly reducing the labor intensity of operators and helping to reduce overall labor costs.

[0026] Preferably, the number of clamping mechanisms 4 on the stone clamping assembly 3 is 3-5.

[0027] At loading station 91, the stone to be processed can be loaded onto the corresponding stone clamping assembly 3. At cutting station 92, a whole piece of stone can be cut into multiple strips. At rough cutting station 93, the cut stone can be rough cut, so that the rough cut stone is cylindrical in shape. At fine cutting station 94, the rough cut stone can be fine cut, so that the fine cut stone is vase-shaped. At polishing station 95, the fine cut stone can be polished.

[0028] Specifically, the clamping mechanism 4 includes a support base 41, a first slide block 42, a second slide block 43, and a sliding drive assembly 44. The two ends of the support base 41 are slidably connected to the rotating disk 2 via the first sliding assembly 45. The first slide block 42 and the second slide block 43 are respectively located on the left and right sides of the upper end of the support base 41 and are slidably connected to the support base 41 via the second sliding assembly 46. The sliding drive assembly 44 is located on the support base 41 and is used to drive the first slide block 42 and the second slide block 43 to move synchronously in opposite directions. The first slide block 42 is provided with a first support shaft. 471, a rotatable first clamping top block 472 is installed at one end of the first support shaft 471, and a rotatable second support shaft 481 is installed on the second slide block 43. A second clamping top block 482 is fixedly installed at one end of the second support shaft 481. The second slide block 43 is provided with a rotary drive assembly 49 for driving the second support shaft 481 to rotate. With this structure, when it is necessary to clamp and fix the stone, the stone can be first hoisted to the corresponding position of the multiple clamping mechanisms 4, and then the first slide block 42 and the second slide block 481 can be driven by the sliding drive assembly 44. The seats 43 move synchronously towards each other, bringing the first slide 42 and the second slide 43 closer together. This allows the first clamping top blocks 472 and the second clamping top blocks 482 on the multiple clamping mechanisms 4 to clamp and fix both ends of the stone, facilitating subsequent processing of the stone. Furthermore, the same clamping pressure can be applied to both ends of the stone, effectively ensuring the integrity of the stone during processing. At the roughing station 93, the finishing station 94, and the polishing station 95, the second support shaft 48 can be driven by the rotary drive assembly 49. 1. The mechanism rotates to facilitate the rotation of the cut stone, enabling roughing, fine cutting, or polishing. After processing, the stone can be hoisted and then the sliding drive assembly 44 drives the first slide block 42 and the second slide block 43 to move synchronously in opposite directions. This causes the first slide block 42 and the second slide block 43 to move away from each other, and the first clamping top block 472 and the second clamping top block 482 on the clamping mechanism 4 to no longer clamp and fix the processed stone, making it easy to remove.

[0029] Specifically, the first sliding component 45 includes a first slider and a first slide rail. The first slider is fixedly installed at both ends of the support base 41, and the first slide rail is fixedly installed on the rotating disk 2. The first slider and the first slide rail are adapted to each other and slide together.

[0030] Specifically, the second sliding component 46 includes a second slider 461 and a second slide groove 462. The lower ends of the first slide base 42 and the second slide base 43 are both fixedly provided with the second slider 461. The second slider 461 is in the shape of an inverted T. The support base 41 is provided with a second slide groove 462 that is adapted to the second slider 461. The second slider 461 is engaged in the second slide groove 462 and the two slide together.

[0031] Specifically, the first clamping top block 472 is conical, and a first clamping groove adapted to the first clamping top block 472 is provided on one end surface of the stone. The second clamping top block 482 is square, and a second clamping groove adapted to the second clamping top block 482 is provided on the other end surface of the stone. Thus, when the second support shaft 481 rotates under the drive of the rotary drive assembly 49, it can easily drive the cut stone to rotate together.

[0032] Specifically, the rotary drive assembly 49 includes a geared motor and a transmission assembly. The geared motor is fixedly mounted on the support base 41. The geared motor is connected to one end of the second support shaft 481 via the transmission assembly. The support base 41 is also equipped with a protective cover for covering the geared motor and the transmission assembly. Preferably, the transmission assembly is a belt drive assembly, a chain drive assembly, or a gear drive assembly.

[0033] Specifically, the sliding drive assembly 44 includes a sliding hydraulic cylinder 441 and a tension spring 442. The two ends of the sliding hydraulic cylinder 441 are fixedly connected to the first slide block 42 and the second slide block 43, respectively. At least one tension spring 442 is fixedly provided between the first slide block 42 and the second slide block 43 and the support base 41. Specifically, one end of the tension spring 442 between the first slide block 42 and the support base 41 is fixedly connected to the first slide block 42, and the other end is fixedly connected to the middle of the support base 41. This allows the tension spring 442 to consistently apply an elastic force towards the second slide block 43 to the first slide block 42. One end of the tension spring 442 between the second slide block 43 and the support base 41 is fixedly connected to the second slide block 43. One end is fixedly connected to the other end, and the other end is fixedly connected to the middle of the support base 41. This allows the tension spring 442 to always apply an elastic force toward the first slide 42 to the second slide 43. In this way, when the extension and retraction of the sliding hydraulic cylinder 441 is controlled and the first slide 42 and the second slide 43 are slid, under the constraint of the elastic force of the tension spring 442 and in conjunction with the adaptive free movement of the sliding hydraulic cylinder 441, the first slide 42 and the second slide 43 can be driven to slide synchronously in opposite directions, so as to facilitate the loading and unloading of stone. For example, when the first slide 42 and the second slide 43 are close to each other, the first clamping top block 472 and the second clamping top block 482 can clamp the stone synchronously from both ends.

[0034] Preferably, two tension springs 442 are fixedly provided between the first slide 42 and the second slide 43 and the support base 41.

[0035] Specifically, the telescopic drive mechanism 5 includes a telescopic hydraulic cylinder 51 and an X-shaped telescopic frame 52. The support seats 41 on the multiple clamping mechanisms 4 are sequentially hinged to multiple central hinge points on the X-shaped telescopic frame 52. The cylinder body of the telescopic hydraulic cylinder 51 is fixedly mounted on the rotating disk 2. The piston rod end of the telescopic hydraulic cylinder 51 is fixedly connected to the innermost support seat 41, and the outermost support seat 41 is fixedly installed. By controlling the extension and retraction of the piston rod of the telescopic hydraulic cylinder 51, the X-shaped telescopic frame 52 can be easily extended and retracted. This allows the multiple support seats 41 to move away from or closer to each other, thus enabling the multiple support seats 41 to... The system switches between a first processing position and a second processing position. When the X-shaped telescopic frame 52 retracts, the multiple support seats 41 will approach and abut against each other, thus being in the first processing position. When the X-shaped telescopic frame 52 extends, the multiple support seats 41 will move away from each other and be spaced apart, thus being in the second processing position. When the stone clamping assembly 3 is in the loading station 91, cutting station 92, and unloading station 96, the multiple support seats 41 on the stone clamping assembly 3 will be in the first processing position. When the stone clamping assembly 3 is in the roughing station 93, fine cutting station 94, and polishing station 95, the multiple support seats 41 on the stone clamping assembly 3 will be in the second processing position.

[0036] Furthermore, the X-shaped telescopic frame 52 can adopt the structure of the prior art, so it will not be described in detail here.

[0037] Furthermore, the first support shaft 471 is movably sleeved within the fixed cylinder 421 and slides within the fixed cylinder 421. The fixed cylinder 421 is fixedly mounted on the upper end of the first slide block 42. A moving drive assembly 422 for moving the first support shaft 471 is provided on one side of the fixed cylinder 421. A guide groove 4711 is provided along the axial direction on the surface of the first support shaft 471. A guide block 423 is provided on the fixed cylinder 421, which is engaged within and adapted to the guide groove 4711. This facilitates good guidance for the movement of the first support shaft 471. Specifically, the moving drive assembly 422 includes a handwheel and a drive screw. One end of the fixed cylinder 421 is fixedly mounted with an end plate. The drive screw is located inside the fixed cylinder 421, and one end of the drive screw passes through the end plate and is fixedly connected to the handwheel. The drive screw is rotatably connected to the end plate through a bearing. The other end of the drive screw is threadedly connected to a threaded hole in the first support shaft 471. In this way, the handwheel can be easily rotated to drive the first support shaft 471 to move, thereby adjusting the extension distance of the first support shaft 471, that is, adjusting the position of the first clamping top block 472, and adjusting the distance between the first clamping top block 472 and the second clamping top block 482, thereby better adapting to the processing of stones of different lengths.

[0038] In other embodiments, the moving drive assembly 422 includes a moving hydraulic cylinder, the cylinder body of which is fixedly mounted on the fixed cylinder 421, and the piston rod end of which is fixedly connected to the first support shaft 471.

[0039] Furthermore, when the stone clamping assembly 3 is in the cutting station 92, a first cutting gap is provided between the first slides 42 on two adjacent clamping mechanisms 4, and a second cutting gap is provided between the second slides 43 on two adjacent clamping mechanisms 4. By setting the first cutting gap and the second cutting gap, a clearance space can be formed for the cutting blade at the cutting station 92, which further facilitates the smooth cutting of the stone by the cutting blade and uniformly cuts the stone into multiple parts.

[0040] In addition, the rotating disk 2 is fixedly provided with a mounting plate 21 for mounting the stone clamping assembly 3. The number of mounting plates 21 is consistent with the number of stone clamping assemblies 3 and corresponds one-to-one. At least one support leg 61 is fixedly installed on the suspended end of the mounting plate 21. A rotatable roller 62 is installed at the bottom of the support leg 61. The roller 62 abuts against the annular guide rail 63 and the two roll in cooperation. The annular guide rail 63 is located on the outside of the rotary drive base 1. The support leg 61 can provide good support for the suspended end of the mounting plate 21, thereby making the overall structure of the rotating disk 2 more stable, less prone to deformation, and providing better load-bearing effect to better support the stone clamping assembly 3 and the stone. At the same time, the rolling of the roller 62 on the annular guide rail 63 ensures the smoothness of the support leg 61 when it rotates with the rotating disk 2. Preferably, the suspended end of the mounting plate 21 is provided with two support legs 61.

[0041] In addition, the mounting plate 21 is provided with a slot 211 that runs through its upper and lower ends, and an annular water collection tank 7 is provided below the slot 211, which facilitates the collection of water during the stone processing.

[0042] Furthermore, a limiting and fixing mechanism 8 is provided between the innermost support base 41 and the mounting plate 21. The limiting and fixing mechanism 8 includes a limiting plate 81, a first limiting pin 82, and a second limiting pin 83. The limiting plate 81 has limiting holes that are adapted to the first limiting pin 82 and the second limiting pin 83. The limiting plate 81 is fixedly installed at both ends of the innermost support base 41. A first limiting hydraulic cylinder 84 and a second limiting hydraulic cylinder 85 are installed on the left and right sides of the lower end of the mounting plate 21. The piston rod end of the hydraulic cylinder 84 is fixedly equipped with the first limiting pin 82, and the piston rod end of the second limiting hydraulic cylinder 85 is fixedly equipped with the second limiting pin 83. When the first limiting hydraulic cylinder 84 drives the first limiting pin 82 to insert into the limiting hole of the limiting plate 81, the multiple support seats 41 can be stably placed in the first processing position. When the second limiting hydraulic cylinder 85 drives the second limiting pin 83 to insert into the limiting hole of the limiting plate 81, the multiple support seats 41 can be stably placed in the second processing position.

[0043] Specifically, the rotary drive base 1 includes a base body 11 and an intermittent drive source 12. The rotating disk 2 is rotatably mounted on the upper end of the base body 11 via a slewing bearing 13. The intermittent drive source 12 is located inside the base body 11 and is used to drive the rotating disk 2 to rotate intermittently. The intermittent drive source 12 is a combination of a servo motor, a stepper motor, or a geared motor and an intermittent separator. For example, a drive gear is fixedly mounted on the motor shaft of the servo motor, and an internal gear is fixedly mounted inside the slewing bearing 13. The drive gear meshes with the internal gear for transmission, thereby facilitating the intermittent rotation of the rotating disk 2 by the servo motor, rotating the rotating disk 2 by 60 degrees each time.

[0044] The above are merely some specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
