Description

Technical Field

[0001] This invention relates to the field of marble grinding technology, and in particular to a surface grinding device for processing precision measuring tools on marble platforms. Background Technology

[0002] In the manufacturing and installation of precision machine tools and other equipment, marble, with its excellent physical properties such as high stability, low coefficient of thermal expansion, and outstanding shock resistance, has become an ideal material for constructing precision worktables. After careful polishing, marble tabletops can provide an extremely flat, stable, and reliable support foundation for precision machine tools, ensuring that the machine tools maintain high-precision machining performance during long-term operation, thereby guaranteeing the dimensional accuracy and quality stability of the produced parts. However, to obtain high-quality marble tabletops that meet the requirements of precision machine tools, the key lies in the fine polishing of the marble surface.

[0003] Currently, traditional marble grinding operations mainly rely on grinding machines. These grinding machines are wet grinding equipment specifically designed for the surface processing of artificial or natural stone such as marble, granite, and terrazzo. They have multiple functions such as coarse grinding, fine grinding, polishing, and renovation. Their working principle is that the grinding disc is driven by a motor to rotate at high speed. During the grinding process, clean water or special grinding fluid is used to cool and lubricate the surface, while also removing the grinding debris, thus achieving a dust-free, efficient, and low-damage grinding effect.

[0004] In the actual polishing process of marble, the surface needs to be sprayed through the spray system of the grinding machine. However, this system has a significant drawback: the spray volume cannot be adjusted at the water outlet, while the grinding machine's spray volume requirements vary greatly at different polishing stages (e.g., coarse polishing requires high-flow cooling, while fine polishing requires low-flow cooling). This problem directly leads to two common problems in actual operation: first, excessive water output wastes water resources; second, insufficient water output results in poor cooling of the marble slab, failing to provide sufficient and suitable cooling. Improper cooling will further affect the polishing quality, potentially causing thermal damage and uneven polishing on the marble surface, ultimately failing to meet the high precision and high quality requirements of precision machine tools for marble countertops.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example, refer to Figures 1-8This is the first embodiment of the present invention. This embodiment provides a surface grinding device for processing a precision measuring tool marble platform. It includes a machine tool 1, a marble grinding machine body 100 mounted on the machine tool 1, a support rod 101 fixed to the bottom of the marble grinding machine body 100, a water tank 200 fixed to the top of the marble grinding machine body 100, a water outlet pipe 203 mounted on the outer surface of the water tank 200, a pressurizing component 300 disposed inside the water tank 200, a power component 400 disposed on the support rod 101, the power component 400 being connected to the pressurizing component 300, an adjusting component 500 disposed at the outlet of the water outlet pipe 203, a locking component 600 fixed on the adjusting component 500, and the machine tool 1 is provided with x-axis and y-axis slide rails. The left and right and forward and backward movement of the marble grinding machine body 100 can be controlled by the x-axis and y-axis slide rails. During the marble grinding process, the marble grinding machine body 100 is controlled to swing left and right or back and forth via the x and y axis slide rails on the machine tool 1; the power component 400 then converts this swinging force into up and down reciprocating motion and transmits it to the pressurizing component 300. The pressurizing component 300 performs work on the water tank 200, using atmospheric pressure to continuously press the water in the water tank 200 through the water outlet pipe 203, realizing automatic water spraying during grinding. This can reduce the surface temperature of the board and suppress dust flying. When changing grinding discs of different mesh sizes, the linkage design of the adjusting component 500 and the locking component 600 allows for precise control of the outlet pipe 203 diameter to match the differentiated needs of coarse grinding (high flow rate) and fine grinding (low flow rate), thus avoiding water waste or insufficient cooling.

[0028] A partition 202 is fixedly connected inside the water tank 200. The pressurizing assembly 300 includes pressurizing rods 301 that are slidably connected to both sides of the partition 202 inside the water tank 200. A connecting block 302 is fixedly connected to the top of each of the two pressurizing rods 301, and a pressurizing semicircle 303 is fixedly connected to the bottom of each of the two pressurizing rods 301. A notch 304 is provided on each of the two pressurizing semicircles 303. A rotating plate 305 is rotatably connected to each of the two pressurizing semicircles 303 at the position of the notch 304. The rotating plate 305 and the pressurizing semicircle 303 have a one-way opening. The rotating plate 305 can only rotate upward and cannot rotate downward.

[0029] Furthermore, two pressurized semicircles 303 are installed inside the water tank 200, and the pressurized semicircles 303 are matched with the spaces separated by the partition 202 inside the water tank 200. Two connecting blocks 302 are installed on the top outside the water tank 200. This allows the two spaces separated by the partition 202 inside the water tank 200 to drain water according to the direction of movement of the grinding machine when the marble grinding machine body 100 moves left and right or up and down.

[0030] Furthermore, a notch 102 is provided on the side of the support rod 101, and two sliding grooves 201 are provided on the outer surface of the water tank 200. The power assembly 400 includes sliding rods 401 slidably connected within the two sliding grooves 201. A conversion rod 402 is fixedly connected to one end of each sliding rod 401. Both ends of the two conversion rods 402 are provided with movable grooves 403. A receiving rod 404 is movably connected inside each of the two top movable grooves 403, and an output rod 405 is movably connected inside each of the two bottom movable grooves 403. An output rod 405 is fixedly connected to the end of one side of the output rod 405. On the other side, output wheel 406 is connected to the end of output rod 405, and output wheel 407 is connected to the end of output rod 407. Output wheel 408 is perpendicular to output wheel 406 and output wheel 408. The sides of output wheel 406 and output wheel 408 are rounded. Output wheel 406 and output wheel 408 are made of rubber. When moving left and right or up and down, the side that cannot move will not affect the normal movement of the grinder due to the rounded shape. At the same time, it will not leave scratches when rubbing against the marble surface.

[0031] Furthermore, the receiving rod 404 is fixedly connected to the connecting block 302, the output wheel 406 is rotatably connected to the support rod 101, and the output wheel 408 is rotatably connected to the notch 102 opened on the support rod 101.

[0032] Furthermore, the adjustment component 500 includes a limiting plate 501 fixedly connected to the outer surface of the water outlet pipe 203. The limiting plate 501 has multiple limiting grooves 502. Each of the multiple limiting grooves 502 is slidably connected to a moving rod 503. Each of the bottom ends of the moving rods 503 is fixedly connected to a blocking block 504. The ends of the multiple blocking blocks 504 that are close to each other are set with arc-shaped openings 505. A rotating disk 506 is rotatably connected to the outer surface of the water outlet pipe 203 above the limiting plate 501. A guide groove 507 is opened on the rotating disk 506 corresponding to the position of the limiting groove 502.

[0033] Furthermore, multiple movable rods 503 are movably connected to guide grooves 507.

[0034] Furthermore, two slots 204 are provided on the outer surface of the water outlet pipe 203. The locking assembly 600 includes a locking half-ring 601 fixedly connected to the top of the rotating disk 506. A rod 602 is fixedly connected to the inner wall of the locking half-ring 601. A spring 603 is fixedly connected between the rod 602 and the outer wall of the locking half-ring 601. The rod 602 and the slot 204 are matched. The positions of the slot 204 and the rod 602 are both chamfered. This way, when rotating, the side of the slot 204 can abut against the rod 602 and move outward.

[0035] During use, when grinding the surface of a marble slab, the marble grinding machine body 100 is controlled to swing left and right or back and forth via the x and y axis slide rails on machine tool 1. As the marble grinding machine body 100 swings back and forth, the output wheel 406 rotates due to friction with the marble surface. During the rotation of the output wheel 406, the connected output rod 405 moves along the outer ring of the output wheel 406. As the output rod 405 moves, its outer surface abuts against the inner wall of the bottom movable groove 403, causing the conversion rod 402 to drive the slide rod 401 along... As the water tank 200 moves along the track of the sliding groove 201 outside the water tank 200, the inner wall of the movable groove 403 at the top of the conversion rod 402 will abut against the receiving rod 404. Since the receiving rod 404 is connected to the connecting block 302, and the connecting block 302 is connected to the pressure rod 301, and the pressure rod 301 is slidably connected to the water tank 200, the receiving rod 404 will also move perpendicularly to the water tank 200. At this time, one side of the pressure rod 301 and the pressure semicircle 303 will reciprocate up and down under the action of the receiving rod 404. When the pressure semicircle 303 moves downward inside the water tank 200, due to the rotating plate 305 The pressure semicircle 303 rotates in one direction. When the pressure semicircle 303 moves downwards, a negative pressure is created. Water in the water tank 200 then flows upwards from the notch 304, submerging the pressure semicircle 303 to fill the negative pressure. As the pressure semicircle 303 moves upwards, the water pressure in the water tank 200 increases, and the rotating plate 305 immediately closes. When the water pressure exceeds the weight of the water column above the rotating plate 305, the rotating plate 305 is pushed open, and water flows through the notch 304 into the upper space of the pressure semicircle 303. This process repeats until the water column in the water tank 200 rises to the position of the outlet pipe 203 and flows out. When the marble grinding machine body 100 swings around, the output wheel 408 will rotate. At this time, the output rod 405 on the other side will drive the bending rod 407 to abut against the inner wall of the bottom movable groove 403, so that the conversion rod 402 on the other side will also move up and down. At this time, the pressure rod 301, connecting block 302 and pressure semicircle 303 on the other side of the water tank 200 will repeat the corresponding action, and discharge the water in the water tank 200 through the water outlet pipe 203 to spray the marble surface, thereby realizing automatic water spraying during grinding. This can reduce the surface temperature and suppress dust flying. When the operator changes the grit size of the grinding disc, the locking half-ring 601 is rotated according to the desired grinding degree of the marble. The locking half-ring 601 will drive the rotating disk 506 to rotate. The inner wall of the guide groove 507 on the rotating disk 506 will abut against the outer surface of the moving rod 503, causing the moving rod 503 to move along the trajectory of the limiting groove 502. At this time, the blocking blocks 504 at the ends of the multiple moving rods 503 will also move accordingly. When the blocking blocks 504 spread outwards from the outlet of the water pipe 203 as the center, the diameter of the outlet of the water pipe 203 will increase, and the water flow will also increase to accommodate the smaller grit size. Similarly, when multiple blocking blocks 504 move towards the center with the outlet of the water pipe 203 as the center, the diameter of the outlet of the water pipe 203 will become smaller, and the water flow will also become smaller to accommodate the larger mesh size of the grinding disc. When the locking ring 601 rotates, the insert rod 602 set on its inner wall moves to the position of the corresponding slot 204, and the spring 603 will push the insert rod 602 into the slot 204 to prevent the rotating disk 506 from moving during the spraying process. This allows for precise control of the diameter of the water pipe 203 to match the differentiated needs of coarse grinding (large flow) and fine grinding (small flow), avoiding water waste or insufficient cooling.

[0036] In summary, during the marble grinding process, the marble grinding machine body 100 on the machine tool 1 swings left and right or back and forth in the x and y directions; the power component 400 then converts this swinging force into up and down reciprocating motion and transmits it to the pressurizing component 300. The pressurizing component 300 performs work on the water tank 200, using atmospheric pressure to continuously press the water in the water tank 200 through the water outlet pipe 203, realizing automatic water spraying during grinding. This not only reduces the surface temperature of the plate but also suppresses dust. When changing grinding discs of different mesh sizes, the linkage design of the adjusting component 500 and the locking component 600 allows for precise control of the outlet pipe 203 diameter to match the differentiated needs of coarse grinding (high flow rate) and fine grinding (low flow rate), thus avoiding water waste or insufficient cooling.
