Description

Technical Field

[0001] This invention relates to the field of stone processing technology, specifically to a cutting and polishing device for building stone. Background Technology

[0002] During the construction process, the laying of stone floor tiles (such as marble and granite) is a basic and important task. In actual construction, since the ground size often does not match the standard specifications of the stone, the stone floor tiles need to be cut and polished on site to obtain individual stone pieces that meet the installation size.

[0003] Currently, the cutting and polishing of stone floor tiles at construction sites mainly uses handheld cutting machines (such as marble cutters) and portable cutting machines (table saws). Because handheld cutting machines produce burrs, chipped edges, or unevenness on the cut surface, a handheld angle grinder is needed to polish and trim the cut edges. Although portable cutting machines can achieve straight-line cutting, the finishing of the cut edges still requires additional polishing tools for secondary processing.

[0004] This results in existing equipment having to perform cutting and polishing as two separate processes, which involves many steps and low efficiency. In addition, handheld cutting and polishing operations are highly dependent on the operator's skill level, and quality defects such as skewed cutting lines and uneven cutting surfaces are prone to occur during cutting. Therefore, it is necessary to propose a cutting and polishing device for building stone to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a cutting and polishing device for building stone, which solves the problems of cutting and polishing stone floor tiles being two separate processes, resulting in cumbersome process switching, low on-site operation efficiency, and poor quality.

[0012] Preferably, the fixing mechanism includes a mounting plate, an air cylinder, a piston, a moving rod, a threaded sleeve, a suction cup seat, an adsorption plate, a sealing ring, and a mounting plate; The number of fixing mechanisms is two. The two fixing mechanisms are respectively fixedly installed on the bottom inner side of the main platform and the auxiliary platform. The mounting plate is fixedly installed on the bottom inner side of the main platform, and the air cylinder is fixedly installed inside the mounting plate. The piston is movably arranged inside the air cylinder, and the moving rod is rotatably installed on one side of the piston.

[0013] Preferably, one end of the moving rod is provided with an external thread, the threaded sleeve is threadedly installed on the external thread end of the moving rod, and the threaded sleeve is fixedly installed inside one side of the main platform, and the air cylinder is connected to the suction cup seat through a pipe; The suction plate is fixedly connected to the top inner wall of the suction cup base, the sealing ring is fixedly connected to the top of the suction cup base, the mounting plate is fixedly installed on the outside of the suction cup base and fixedly connected to the main platform, and the suction cup base passes through and extends out of the inner side of the reserved hole.

[0014] Preferably, the positioning mechanism includes a slide groove, a slider, a positioning plate, a fixing plate, a fastening stud, and a side stop; The slide grooves are evenly spaced on the top of the main platform, and the slider is slidably disposed inside the slide grooves.

The fixing plate is fixedly connected to one side of the positioning plate, and the fastening stud is threadedly installed inside the fixing plate, with the bottom end of the fastening stud abutting against the top of the main platform. There are two side guards, which are fixedly connected to the top side of the main platform and the sub-platform respectively. One side of the positioning plate is slidably set on the top of the dimension line, and the positioning plate and the side guards are set perpendicular to each other.

[0015] Preferably, a cover plate assembly is installed inside the reserved hole, and the cover plate assembly includes a cover plate sheet, a magnetic strip one, and a magnetic strip two; The first magnetic strip is symmetrically embedded inside both sides of the cover plate, and the second magnetic strip is symmetrically embedded inside both sides of the reserved hole, and the second magnetic strip and the first magnetic strip are magnetically attracted to each other. A triangular notch is formed between one corner of the cover plate and the reserved hole. The cover plate is pressed and adhered to the top of the sealing ring and the adsorption sheet, and the top of the cover plate is flush with the top of the main platform and the sub-platform.

[0016] Working principle: First, the main platform and the auxiliary platform are adjusted to be close together using the split screw, so that a cutting gap is formed between them. Then, the stone floor tile to be processed is placed on the top of the platform and positioned by the positioning plate and side strip. The bottom of the stone is squeezed to make the adsorption plate deform and fit, achieving pre-adsorption and fixation. Then, the operator rotates the moving rod, and the piston moves in the air cylinder to draw air out of the suction cup seat, so that the adsorption plate is tightly adsorbed to the bottom surface of the stone, completing the firm fixation of the stone.

[0017] After fixing, the rotating lifting screw causes the moving block to move downward under the guidance of the limit rod. Then, through the sliding pair and connecting arm, the cutting swing arm is pressed down. The cutting swing arm swings downward around the central axis, while simultaneously driving the grinding swing arm on the other side of the central axis to swing upward. This causes the cutting mechanism to descend into the cutting position and the grinding mechanism to rise for standby. Then, the cutting motor is started, pushing the platform assembly to move along the guide rod and guide rail to the side of the cutting mechanism, so that the rotating blade enters the cutting gap to perform a straight cut on the stone.

[0018] After cutting, rotate the split screw in the opposite direction to move the main platform and the auxiliary platform in opposite directions, separating the two cut stones to form a grinding channel. Then rotate the lifting screw in the opposite direction to swing the cutting arm up and the grinding arm down, switching the grinding mechanism to the grinding position. Start the grinding motor to drive the bidirectional grinding wheel to rotate, and push the platform assembly again to make the bidirectional grinding wheel enter the grinding channel to grind and trim the cut surfaces of the two stones simultaneously. After grinding is completed, reverse the moving rod to release the suction, and the processed stone can be removed.

[0019] This invention provides a cutting and polishing device for building stone. It has the following beneficial effects: 1. This invention integrates and switches between the cutting and grinding processes by installing the cutting mechanism and the grinding mechanism on both sides of the switching mechanism. When the cutting arm is pressed down, it can drive the central shaft to rotate, causing the grinding arm to swing up synchronously. Alternatively, the operation can be reversed to move the grinding mechanism down to the working position and the cutting mechanism up for standby. This allows for the integration and switching of the cutting and grinding processes. After cutting, there is no need to transfer or re-clamp the stone floor tiles. The process can be directly switched to the grinding station for edge trimming, which improves the efficiency of stone cutting and grinding.

[0020] 2. This invention sets a positioning plate and side guards on the top of the platform components, and sets dimension lines on the top of the sides of the main platform and the secondary platform. During construction, the stone floor tiles only need to be placed against the positioning plate and side guards to achieve precise positioning. At the same time, through the splitting and joining mechanism between the main platform and the secondary platform, after cutting, the two pieces of stone can be separated to the sides to form a grinding channel. Grinding can be carried out without readjusting the position of the stone, which improves the convenience of operating the cutting and grinding device.

[0021] 3. This invention, by setting a fixing mechanism inside the platform component, allows for pre-adsorption of the stone by gravity-pre-pressing the adsorption sheet to expel some air. Then, a rotating moving rod drives a piston to move inside the air cylinder to extract air from the suction cup seat, ensuring the adsorption sheet is tightly attached to the bottom of the stone and achieving negative pressure fixation. This effectively prevents the stone from shifting due to vibration during cutting and grinding, ensuring processing accuracy and operational safety. At the same time, the cover plate component selectively covers unused suction cup seats, ensuring that the suction force is only applied to the suction cups supporting the stone during air extraction, preventing air leakage from affecting the fixing effect and improving the stability and reliability of the device.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see the appendix Figure 1 Appendix Figure 7 and attached Figure 13This invention provides a cutting and polishing device for building stone, including a cutting mechanism 1, a switching mechanism 3 installed on one side of the cutting mechanism 1, a polishing mechanism 2 installed on one side of the switching mechanism 3, a frame 4 fixedly installed on one side of the switching mechanism 3, a moving mechanism 5 provided on the top of the frame 4, a platform component 7 installed on the top of the moving mechanism 5, a fixing mechanism 8 installed inside the platform component 7, a positioning mechanism 9 provided on the top of the platform component 7, a dimension line 73 is set in two segments, and the two segments of dimension line 73 are respectively fixedly set on the top of the side of the main platform 71 and the secondary platform 72, a cutting gap is reserved between the main platform 71 and the secondary platform 72, and the starting point of the dimension line 73 is on both sides of the cutting gap; The slide grooves 91 are evenly spaced on the top of the main platform 71, and the slider 92 is slidably disposed inside the slide grooves 91. The positioning plate 93 is fixedly connected to one side of the slider 92, and the positioning plate 93 is slidably disposed on the top of the main platform 71 through the slider 92. The fixing plate 94 is fixedly connected to one side of the positioning plate 93. The fastening stud 95 is threadedly installed inside the fixing plate 94, and the bottom end of the fastening stud 95 abuts against the top of the main platform 71. There are two side stops 96, and the two side stops 96 are fixedly connected to the top side of the main platform 71 and the sub-platform 72 respectively. One side of the positioning plate 93 is slidably disposed on the top of the dimension line 73. The positioning plate 93 and the side stops 96 are perpendicular to each other.

[0026] When laying stone floor tiles at a construction site, if the size of the stone floor tiles is not suitable and needs to be cut at the corners, firstly, the main platform 71 and the secondary platform 72 are adjusted to the required cutting state through the splitting screw 64 of the splitting mechanism 6, that is, the main platform 71 and the secondary platform 72 are closest to each other. At this time, there is a cutting gap between the two. Then, the suction cup seat 86 and suction plate 87 that are not needed are covered by the cover plate assembly 10 as needed. Then, the position of the positioning plate 93 is adjusted, and the positioning plate 93 is pushed to make the slider 92 slide inside the slide groove 91, thereby making the positioning plate 93 slide on the top of the main platform 71. Simultaneously, one side of the positioning plate 93 moves at the top of the dimension line 73, thereby accurately positioning the position of the positioning plate 93 through the dimension line 73. After the positioning plate 93 moves to the required position, the fastening stud 95 is rotated downward and abuts against the top of the main platform 71, thereby fixing the fixing plate 94 and the positioning plate 93 through friction. Then, the stone floor tile to be cut and polished is first placed vertically on one side of the positioning plate 93, and then the stone floor tile is moved towards the side baffle 96, and the two sides of the stone floor tile are placed against the positioning plate 93 and the side baffle 96. Then, the stone floor tile is laid down on the top of the main platform 71 and the secondary platform 72, at which point the positioning of the stone floor tile is completed.

[0027] Please see the appendix Figure 7 Appendix Figure 10 -Appendix Figure 12 Appendix Figure 14 and attached Figure 15 There are two fixing mechanisms 8. The two fixing mechanisms 8 are fixedly installed on the bottom inner side of the main platform 71 and the auxiliary platform 72 respectively. The mounting plate 81 is fixedly installed on the bottom inner side of the main platform 71, and the air cylinder 82 is fixedly installed inside the mounting plate 81. The piston 83 is movably installed inside the air cylinder 82, and the moving rod 84 is rotatably installed on one side of the piston 83. One end of the moving rod 84 is provided with an external thread. The threaded sleeve 85 is threaded onto the external thread end of the moving rod 84, and the threaded sleeve 85 is fixedly installed inside one side of the main platform 71. The air cylinder 82 is connected to the suction cup seat 86 through a pipe. The suction cup seat 86 is a cylindrical structure with an adsorption plate 87 fixed at the top opening. The sealing ring 88 is fixedly connected to the top of the suction cup seat 86. The mounting plate 89 is fixedly installed on the outside of the suction cup seat 86 and fixedly connected to the main platform 71. The suction cup seat 86 passes through and extends into the inside of the reserved hole 74. After the stone floor tile is positioned by the positioning mechanism 9, it is fixed by the fixing mechanism 8. The top of the suction cup seat 86 and the suction plate 87 are made of deformable elastic rubber, and the bottom of the suction cup seat 86 is made of PVC, which makes it easy to fix with the mounting plate 89. The suction plate 87 has a bucket-shaped structure and an air hole in the center. The sealing ring 88 is made of silicone, which allows for better tight fit when encountering uneven stone, while reducing the impact of vibration during stone cutting and grinding on the suction fixation. Specifically, after the stone floor tile is placed on top of the main platform 71 and the secondary platform 72, the bottom of the stone floor tile is squeezed to deform the sealing ring 88 and make the sealing ring 88 fit against the bottom of the stone floor tile. The weight of the stone floor tile presses down the top of the suction cup seat 86, expelling some air and causing the adsorption sheet 87 to be squeezed against the bottom of the stone floor tile for pre-adsorption and fixation. Then, the handle at the outer end of the moving rod 84 is held and rotated, thereby rotating the moving rod 84 inside the piston 83. Simultaneously, the moving rod 84 rotates and moves inside the threaded sleeve 85, causing the moving rod 84 to pull the piston 83 to move inside the air cylinder 82. This allows air between the adsorption sheet 87 and the stone floor tile to enter the suction cup seat 86 through the air hole. Then, the air inside the top of the suction cup seat 86 is drawn into the air cylinder 82, causing the adsorption sheet 87 to fit tightly against the bottom of the stone floor tile. At the same time, the pressure inside the suction cup seat 86 is increased, thereby fixing the stone floor tile. After the stone floor tile has been cut and polished, simply rotating the moving rod 84 in the opposite direction allows air from inside the air cylinder 82 to enter multiple suction cup seats 86, removing the adsorption force between the adsorption sheet 87 and the stone floor tile, thus facilitating the removal of the stone floor tile.

[0028] Please see the appendix Figure 12 and attached Figure 15The reserved holes 74 are equally spaced on the top of the main platform 71 and the sub-platform 72. Magnetic strip 102 is symmetrically embedded in the inner sides of the cover plate 101. Magnetic strip 2 103 is symmetrically embedded in the inner walls of the reserved holes 74. Magnetic strip 2 103 and magnetic strip 102 are magnetically attracted to each other. A triangular notch is formed between one corner of the cover plate 101 and the reserved hole 74. The cover plate 101 is pressed and adhered to the top of the sealing ring 88 and the adsorption plate 87. The top of the cover plate 101 is flush with the top of the main platform 71 and the sub-platform 72. When covering the unused suction cup base 86 and suction plate 87, simply align the magnetic strips 102 on both sides of the cover plate 101 with the magnetic strips 103 inside the reserved holes 74, and then press down on the cover plate 101 to complete the covering. When pressing the cover plate 101, the air inside the suction plate 87 and suction cup base 86 is squeezed into the pipe, thereby expelling the air from the air holes of other connected suction plates 87. At the same time, the magnetic strips 102 magnetically attract the magnetic strips 103 to fix the position of the cover plate 101, so that the cover plate 101 is attached to the top of the suction plate 87. Therefore, when the stone floor tile placement platform assembly 7 is placed on top of other suction plates 87, air will not enter from the unused suction plates 87 when the gas inside the pipe is extracted, thus ensuring the stability of the fixing mechanism 8. After use, when it is necessary to remove the cover plate 101, simply insert your fingers into the notch and pinch the side of the cover plate 101 to remove the cover plate 101 upwards.

[0029] Please see the appendix Figure 1 Appendix Figure 3 -Appendix Figure 6 and attached Figure 8 The switching mechanism 3 includes a fixed box 31, a lifting screw 32 rotatably installed inside the fixed box 31, a moving block 33 threadedly installed outside the lifting screw 32, a sliding pair 35 slidably installed on one side of the moving block 33, a rotating shaft 36 rotatably installed on one side of the sliding pair 35, a cutting swing arm 38 hinged to the rotating shaft 36, a central shaft 39 fixedly installed on one side of the cutting swing arm 38, and a grinding swing arm 30 fixedly installed outside the central shaft 39. The cutting mechanism 1 is fixedly installed on the top of the cutting swing arm 38, and the grinding mechanism 2 is fixedly installed on the top of the grinding swing arm 30. The central shaft 39 is rotatably installed on one side of the fixed box 31. When the cutting swing arm 38 is pressed down, the grinding swing arm 30 is raised by rotating the central shaft 39. The cutting mechanism 1 and the grinding mechanism 2 switch their positions by swinging the cutting swing arm 38 and the grinding swing arm 30 up and down. The cutting motor 11 is fixedly installed with a mounting bracket on the outside. The mounting bracket is fixedly installed on the top of the cutting swing arm 38, and the blade 12 is installed on one end of the output shaft of the cutting motor 11. The protective cover 13 covers the outside of the blade 12 and is fixedly connected to the cutting swing arm 38 through the mounting bracket. The switching mechanism 3 also includes a limiting rod 34 and a connecting arm 37. The limiting rod 34 is symmetrically fixedly installed inside the fixed box 31 and is slidably connected to the moving block 33. The connecting arm 37 is fixedly installed between the rotating shaft 36 and the cutting swing arm 38. One side of the moving block 33 has a T-shaped structure, and a groove matching the T-shaped structure is opened on one side of the sliding pair 35. The sliding pair 35 is slidably sleeved on one side of the moving block 33. The guide rod 51 is symmetrically fixedly installed on both sides of the top of the frame 4, and the guide rail 52 is symmetrically fixedly installed on the top of the frame 4. The guide block 53 is slidably disposed outside the guide rod 51, and the roller 54 is slidably disposed on the top of the guide rail 52. The guide rod 51 and the guide rail 52 both extend along the direction from the cutting mechanism 1 to the grinding mechanism 2. After fixing the stone floor tiles, hold the handle at the top of the lifting screw 32 and rotate it clockwise. This causes the moving block 33 to move downward under the limit of the limiting rod 34, thereby pressing the cutting arm 38 downward through the connecting arm 37. The connecting arm 37 rotates on one side of the sliding pair 35, and the sliding pair 35 slides outside the moving block 33, decoupling the moving block 33 and the cutting arm 38. When the cutting arm 38 is pressed down, it drives the central shaft 39 to rotate, thereby causing the grinding arm 30 to swing upward. This causes the cutting mechanism 1 to move downward into the cutting position, and the grinding mechanism 2 to move upward for standby. Then, turn on the cutting power. Coolant is applied to one side of the machine 11 and the blade 12. The user then holds one side of the main platform 71 and pushes it towards the cutting mechanism 1, causing the guide block 53 to slide outside the guide rod 51 and the roller 54 to roll on the top of the guide rail 52. The stone floor tile is then moved to the bottom of the blade 12, and the stone floor tile is cut with the help of the sprayed coolant. As the main platform 71 is pushed, the stone floor tile is moved, and the blade 12 moves in the cutting gap until the stone floor tile is cut. At this point, the stone floor tile is divided into two pieces, which are fixed on the top of the main platform 71 and the secondary platform 72 respectively, thus completing the stone floor tile cutting operation.

The moving plates 66 are set in two groups, and the two groups of moving plates 66 are symmetrically fixedly installed on the bottom inner side of the main platform 71 and the secondary platform 72 respectively. After cutting, the stone floor tile is divided into two pieces. At this time, the stone floor tile is a certain distance away from the grinding mechanism 2. Hold the handle at one end of the splitting screw 64 and rotate it to make the splitting screw 64 rotate inside the fixed box 63. Then, the two displacement blocks 65 at the bottom of the main platform 71 and the secondary platform 72 move relative to each other. At the same time, the moving plate 66 slides and limits itself inside the limiting slide plate 62, so that the main platform 71 and the secondary platform 72 move outward, increasing the distance between the two stone floor tiles, thereby forming a grinding channel that can be passed through the bidirectional grinding wheel 24. Then, by rotating the lifting screw 32 in the opposite direction, the cutting arm 38 is swung upward, thereby pressing down the grinding arm 30, causing the grinding mechanism 2 to move down to the grinding station. Next, the grinding motor 21 is turned on, and through the multiple gears of the gear set 22, the transmission shaft 23 drives the bidirectional grinding wheel 24 to rotate. Then, the platform assembly 7 is pushed to move to one side of the grinding mechanism 2, so that the bidirectional grinding wheel 24 enters the grinding channel between the main platform 71 and the auxiliary platform 72. With the use of coolant, as the platform assembly 7 moves, the cut surfaces of the two stone floor tiles are ground simultaneously. Therefore, no matter which stone floor tile is used, no secondary grinding is required. After grinding is completed, the suction fixation is released by rotating the moving rod 84. Finally, the cut and ground stone floor tile can be removed for use.
