Abstract
Description
Technical Field
[0001] This application relates to the field of granite processing technology, and in particular to a granite surface polishing device. Background Technology
[0002] Granite is a type of stone that naturally metamorphoses under high temperature, high pressure, and the combined action of minerals. Due to its hardness, density, high strength, resistance to weathering, corrosion, and wear, and low water absorption, granite is widely used in various construction industries. When processing granite, it needs to be cut and polished according to the intended use to ensure the desired color and smoothness of its surface.
[0003] A polishing device is proposed in related technologies, including a worktable, a polishing mechanism, and a clamping mechanism. The polishing mechanism is located on the top of the worktable, and the clamping mechanism is symmetrically located on both sides of the worktable. It includes an electric slide rail vertically mounted on the worktable, an electric telescopic rod slidably connected within the electric slide rail, a connecting plate at the end of the electric telescopic rod, and a slot block rotatably connected to a rotating shaft. In use, the workpiece is placed on the worktable, and the electric telescopic rods on both sides are driven to extend, causing the slot blocks to press against both sides of the workpiece. Then, the polishing mechanism at the top polishes one side of the workpiece. After one side is polished, the electric slide rail drives the electric telescopic rod to rise, driving the rotating shaft to rotate and flip the workpiece disc, thus completing the polishing operation on the other side of the workpiece.
[0004] Regarding the aforementioned technologies and mechanisms, although they can achieve the flipping of granite and thus polish both sides, during the flipping process, due to the heavy weight of granite, if the clamping blocks hold the workpiece too tightly, it is easy to cause damage to the workpiece. If the clamping blocks hold the workpiece too loosely, it is easy for the workpiece to slip during the flipping process, which poses a safety hazard. Utility Model Content
[0005] To address the issues of workpiece breakage due to excessive clamping of the workpiece by the slot block and slippage during workpiece flipping due to excessively loose clamping, this application provides a granite surface polishing device.
[0006] The granite surface polishing device provided in this application adopts the following technical solution:
[0007] A granite surface polishing device includes a base, a rotating table, a mounting frame, a lifting plate, and a polishing mechanism. The rotating table is rotatably connected to the base, and a slot block is provided on the rotating table. The base is provided with a drive assembly for driving the rotating table to rotate. The mounting frame is mounted on the base, and the lifting plate is slidably connected to the mounting frame along the vertical direction. A slot block corresponding to the slot block on the rotating table is also rotatably connected to the lifting plate. The polishing mechanism is located on the lifting plate, and the mounting frame is provided with a first linear drive component for driving the lifting plate to move up and down.
[0008] By adopting the above technical solution, the lifting plate is driven to rise and fall by the first linear drive component, so that the rotating table and the slot blocks on the lifting plate cooperate to fix granite at different heights. The rotating table can be turned by the drive component to achieve the flipping of the granite. With the polishing mechanism, the polishing operation of both sides of the granite can be achieved. The granite is stuck in the upper and lower slot blocks, which makes it more stable when flipping. This improves the problem in the prior art that the slot blocks clamp the workpiece too tightly, which is easy to cause the workpiece to break, while the slot blocks clamp the workpiece too loosely, which is easy to cause the workpiece to slip during the flipping process, which poses a safety hazard.
[0009] Optionally, the drive assembly includes a worm gear, a worm, and a first rotating motor. The worm gear is coaxially connected to the rotating platform, the worm is rotatably connected to the base, and the worm gear meshes with the worm. The first rotating motor is mounted on the base, and the rotating shaft of the first rotating motor is connected to the worm.
[0010] By adopting the above technical solution, the first rotating motor drives the worm to rotate. Since the worm wheel meshes with the worm, the rotation of the worm will drive the worm wheel to rotate. The worm wheel is coaxially connected to the rotating platform, thereby causing the rotating platform to rotate vertically on the base, realizing the drive of the rotating platform to rotate, which facilitates multi-directional polishing of granite. The worm wheel and worm gear transmission has self-locking properties and transmits a large torque, thereby making the rotating platform stably stop at the required position and improving the stability of the polishing operation.
[0011] Optionally, the polishing mechanism includes a sliding seat, a slider, a second linear drive, a rotary motor, and a grinding wheel. The sliding seat is slidably connected to the lifting plate in a horizontal direction, the slider is slidably connected to the sliding seat in a vertical direction, the second linear drive is disposed on the slider in a horizontal direction, the rotary motor is disposed on the output end of the second linear drive, and the grinding wheel is disposed on the rotating shaft of the rotary motor. The lifting plate is provided with a moving component for driving the sliding seat to move, and the sliding seat is provided with a lifting component for driving the slider to rise and fall.
[0012] By adopting the above technical solution, the moving component can drive the sliding seat to slide laterally on the lifting plate, changing the lateral position of the grinding wheel; the lifting component can drive the slider to slide vertically on the sliding seat, adjusting the vertical height of the grinding wheel; the second linear drive component can enable the rotating motor and the grinding wheel to move further laterally, and the rotating motor drives the grinding wheel to rotate, thereby realizing the flexible polishing treatment of the granite surface at different positions and heights by the polishing mechanism.
[0013] Optionally, the moving component includes a gear, a rack, and a stepper motor. The rack is mounted on the lifting plate along the sliding direction of the sliding seat, the stepper motor is mounted vertically on the sliding seat, and the gear is mounted on the rotating shaft of the stepper motor. The gear meshes with the rack.
[0014] By adopting the above technical solution, a moving component consisting of gears, racks and stepper motors is used. The stepper motor drives the gears to rotate and mesh with the racks, which drives the sliding seat to slide laterally on the lifting plate. This allows the polishing mechanism to adjust its lateral position more flexibly, improving the polishing efficiency and effect on the granite surface.
[0015] Optionally, the lifting assembly includes a screw and a second rotating motor. The screw is rotatably connected to the sliding seat about a vertical direction and passes through the slider and is threadedly connected to the slider. The second rotating motor is mounted on the sliding seat, and the rotating shaft of the second rotating motor is connected to the screw.
[0016] By adopting the above technical solution, the second rotating motor drives the screw to rotate. Since the screw is threadedly connected to the slider and the screw is connected to the sliding seat in a vertical rotation, the slider can move vertically along the screw, thereby driving the rotating motor and grinding wheel installed on the slider to achieve lifting and lowering, so as to meet the polishing needs of granite surfaces of different heights. The slider is driven by a transmission method that is threadedly connected to the screw, making the movement of the slider more stable and reliable.
[0017] Optionally, an adjusting rod is threadedly connected to the slot block, and one end of the adjusting rod, which is inserted into the slot of the slot block, is rotatably connected to a pressure plate around the axis of the adjusting rod.
[0018] By adopting the above technical solution, an adjustable rod with a threaded adjustment is set on the slot block, and the end of the adjusting rod is rotatably connected to the pressure plate. This allows the position of the pressure plate in the slot to be adjusted, making it convenient to clamp and fix granite of different thicknesses and sizes, ensuring the stability of the granite during the polishing process, and improving the effect and quality of the polishing treatment.
[0019] Optionally, a buffer pad layer is provided inside the card slot block and on the pressure plate.
[0020] By adopting the above technical solution, the buffer layer can prevent damage to the granite due to excessive pressure when fixing it, thus protecting the granite.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The coordinated arrangement of the rotating table, two slot blocks, drive assembly, and polishing mechanism allows the granite to be stably clamped and fixed, and the rotation of the rotating table enables the granite to be stably flipped, thereby achieving precise polishing of both sides of the granite. During the flipping process, the granite remains supported and stably clamped, which improves the existing technology where the slot blocks clamp the workpiece too tightly, which can easily cause workpiece breakage, while the slot blocks clamp the workpiece too loosely, which can easily cause the workpiece to slip during the flipping process, posing a safety hazard.
[0023] 2. The meshing transmission of the worm gear and worm achieves stable drive of the rotation of the turntable, which facilitates multi-directional polishing of granite. The self-locking property of the worm gear transmission can make the turntable stop stably in the required position, improving the stability of the polishing operation.
[0024] 3. The matching arrangement of the adjusting rod and the pressure plate enables clamping and fixing of granite of different thicknesses, improving the applicability of the polishing device of this application. The structure is simple and easy to use. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses an apparatus for polishing granite surfaces. (Refer to...) Figure 1-2 The granite surface polishing device includes a base 1, a rotating table 2, a mounting frame 3, a lifting plate 4, and a polishing mechanism. The rotating table 2 is vertically rotatably connected to the base 1 via bearings. A slot block 5 is fixedly installed at the top center of the rotating table 2, and the slot block 5 has a slot for accommodating granite. The base 1 is equipped with a drive assembly for driving the rotating table 2 to rotate, thereby causing the granite placed on the rotating table 2 to rotate accordingly.
[0032] Mounting frame 3 is mounted on base 1. Mounting frame 3 specifically includes two vertical rods and a horizontal plate. The two vertical rods are welded and fixed to the top two sides of the base 1, and the horizontal plate is welded and fixed to the top of the two vertical rods. The lifting plate 4 is slidably sleeved on the two vertical rods at both ends, thereby realizing the function of sliding vertically connected to mounting frame 3. Polishing mechanism is mounted on lifting plate 4, and a slot block 5 is also rotatably connected on lifting plate 4 directly above the slot block 5 on rotating table 2. Mounting frame 3 is provided with a first linear drive component 31 for driving lifting plate 4 to rise and fall. The first linear drive component 31 can be an electric push rod, cylinder, etc. It can push lifting plate 4 to move up and down, thereby adjusting the distance between the slot block 5 on lifting plate 4 and the slot block 5 on rotating table 2, so as to position the upper and lower ends of granite and adapt to the clamping and fixing of granite of different heights.
[0033] In use, the granite slab is directly clamped into the slot of the clamping block 5 on the rotating table 2. The clamping block 5 on the rotating table 2 supports the granite. Then, the first linear drive component 31 drives the lifting plate 4 to descend, causing the clamping block 5 on the lifting plate 4 to press firmly onto the granite slab, thus achieving stable clamping and fixing of the granite. Next, the polishing mechanism polishes one side of the granite. After one side is polished, the drive component drives the rotating table 2 to rotate 90 degrees, causing the granite to flip over. The polishing mechanism then completes the polishing of both sides of the granite. During the flipping process, the granite remains supported and stably clamped, improving upon the existing technology where the clamping block 5 clamps the workpiece too tightly, easily causing workpiece breakage, while the clamping block 5 clamps the workpiece too loosely, easily causing the workpiece to slip during flipping, posing a safety hazard.
[0034] Furthermore, refer to Figure 1 and Figure 3An adjusting rod 51 is threaded along the transverse direction on the slot block 5. One end of the adjusting rod 51, inserted into the slot of the slot block 5, is rotatably connected to a pressure plate 52 around its axis. Both the slot block 5 and the pressure plate 52 are provided with buffer pads 53. When the granite is placed in the slot of the slot block 5, rotating the adjusting rod 51 can cause the pressure plate 52 to press firmly against the side wall of the granite, thereby further locking the granite. This also allows the polishing device of this application to be adapted to clamping and fixing granite of different thicknesses, improving the applicability of the polishing device. The buffer pads 53 prevent damage to the granite due to excessive pressure when fixing it, thus protecting the granite.
[0035] For example, the drive assembly includes a worm gear 21, a worm 22, and a first rotary motor 3523. The worm gear 21 is coaxially connected to the rotary table 2, and the worm 22 is rotatably connected to the base 1. A bearing seat can be provided on the base 1 to support the rotation of the worm 22. The worm gear 21 meshes with the worm 22, and this meshing transmission can achieve the functions of deceleration and torque increase. The first rotary motor 3523 is bolted and fixed to the base 1, and the rotating shaft of the first rotary motor 3523 is connected to the worm 22. After the first rotary motor 3523 starts, it drives the worm 22 to rotate, and the worm 22 then drives the worm gear 21 to rotate, ultimately causing the rotary table 2 to rotate. Moreover, the worm gear 21 and worm 22 transmission has self-locking properties and transmits a large torque, which can make the rotary table 2 stably stop at the required position, improving the stability of the polishing operation. The first rotating motor 3523 here can be a servo motor, which has the advantages of high precision and wide speed range; the worm 22 and worm wheel 21 can be made of alloy steel to improve their wear resistance and load-bearing capacity.
[0036] For example, the polishing mechanism includes a sliding seat 32, a slider 33, a second linear drive 34, a rotary motor 35, and a grinding wheel 36. The top of the sliding seat 32 is slidably connected to the lifting plate 4 along the lateral direction. The lifting plate 4 is provided with a moving component for driving the sliding seat 32 to move. The slider 33 is slidably connected to the sliding seat 32 along the vertical direction. The sliding seat 32 is provided with a lifting component for driving the slider 33 to rise and fall. The second linear drive 34 is fixedly installed on the slider 33 along the lateral direction. The second linear drive 34 can be a hydraulic cylinder. The rotary motor 35 is fixedly installed on the output end of the second linear drive 34. The grinding wheel 36 is detachably connected to the rotating shaft of the rotary motor 35. The rotary motor 35 can be a high-speed motor.
[0037] Once the granite is securely clamped and fixed, the rotating motor 35 is started to drive the grinding wheel 36 to rotate at high speed. The grinding wheel 36 polishes the surface of the granite under high-speed rotation. At the same time, the moving component drives the sliding seat 32 to slide laterally on the lifting plate 4, changing the lateral position of the grinding wheel 36. The lifting component drives the slider 33 to slide vertically on the sliding seat 32, adjusting the vertical height of the grinding wheel 36. This allows the polishing mechanism to flexibly polish the granite surface at different positions and heights.
[0038] Specifically, the moving component includes a gear 321, a rack 322, and a stepper motor 323. The rack 322 is fixedly connected to the lifting plate 4 along the sliding direction of the sliding seat 32. The stepper motor 323 is fixedly mounted vertically on the sliding seat 32. The gear 321 is connected to the rotating shaft of the stepper motor 323, and the gear 321 meshes with the rack 322. After the stepper motor 323 starts, it drives the gear 321 to rotate, and the gear 321 rolls on the rack 322, thereby causing the sliding seat 32 to move laterally on the lifting plate 4. Here, the stepper motor 323 can precisely control the rotation angle and number of steps to achieve precise adjustment of the position of the sliding seat 32. The tooth profile of the gear 321 and the rack 322 can adopt an involute tooth profile, which has the advantages of smooth transmission and high efficiency.
[0039] Specifically, the lifting assembly includes a screw 324 and a second rotary motor 35325. The screw 324 is vertically rotatably connected to a sliding seat 32. A bearing can be installed on the sliding seat 32 to support the rotation of the screw 324. The screw 324 passes through and is threadedly connected to the slider 33. This threaded connection converts the rotation of the screw 324 into the linear motion of the slider 33. The second rotary motor 35325 is mounted on the sliding seat 32, and its rotating shaft is connected to the screw 324. After the second rotary motor 35325 is started, it drives the screw 324 to rotate, thereby causing the slider 33 to move up and down on the sliding seat 32.
[0040] The implementation principle of the granite surface polishing device in this embodiment is as follows: During use, the granite is placed directly into the slot of the slot block 5 on the rotating table 2. Then, the adjusting rod 51 is rotated to drive the pressure plate 52 closer to the side wall of the granite, thereby stably clamping and fixing the granite in the slot of the slot block 5. Next, the first linear drive member 31 drives the lifting plate 4 to descend, causing the slot block 5 on the lifting plate 4 to also press against the top of the granite, and the adjusting rod 51 locks the top of the granite, ultimately achieving stable fixation of the granite. Then, the second linear drive member 34 is driven to extend, causing the grinding wheel 36 on the rotating motor 35 to approach the granite, and the rotating motor 35 is started to drive the grinding wheel 36 to rotate at high speed to polish the granite. Simultaneously, stepper motors 323 are activated, driving the sliding seat 32 to move via the meshing transmission of gears 321 and rack 322, thus changing the lateral position of the grinding wheel 36. The second rotary motor 35325 is activated, driving the screw 324 to rotate, causing the slider 33 to slide vertically on the sliding seat 32, adjusting the vertical height of the grinding wheel 36, thereby polishing one side of the granite. After polishing one side is complete, the second linear drive component 34 is retracted, and then the first rotary motor 3523 is activated, driving the rotating table 2 to rotate 90° via the transmission of worm gear 21 and worm 22, thus flipping the granite. The other side of the granite is then polished again via the polishing mechanism. The granite is held in the upper and lower slots 5, making it more stable during flipping. This improves upon the existing technology where the slots 5 clamp the workpiece too tightly, easily causing workpiece breakage, while the slots 5 clamp the workpiece too loosely, easily causing the workpiece to slip during flipping, posing a safety hazard.
[0041] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
