Description

Technical Field

[0001] The utility model relates to the field of ceramic polishing, in particular to a ceramic polishing machine which is convenient for replacing a polishing roller. Background Art

[0002] Ceramic polishing is to further improve the surface accuracy after ceramic grinding, using soft elastic or viscoelastic tools and micro-powder abrasives to make the surface of the workpiece reach the finish of a mirror. In the prior art, a polishing machine can polish and grind a ceramic insulation board of a specified size through a polishing roller. After a certain period of use, the surface of the polishing roller will produce a certain degree of wear, and the polishing roller needs to be disassembled and replaced. The traditional polishing roller is fixedly connected to the polishing machine by bolts, so that special tools are needed to disassemble and replace the bolts on the polishing roller. This replacement method is time-consuming and labor-intensive. Therefore, the application number: CN202320983736.X discloses a ceramic polishing machine that is easy to replace the polishing roller, which relates to the technical field of ceramic insulation board polishing machines , including: an equipment main body, a processing table, a control box, a rotating shaft, a polishing and grinding roller and a card slot. The surface of the equipment main body is connected to the processing table through a slide rail, the control box is installed on the top of the equipment main body through screws, and the front part of the equipment main body is connected to the rotating shaft. The ceramic polishing machine that is convenient for replacing the polishing roller can polish and grind the surface of the workpiece. Usually, the polishing and grinding roller needs to be replaced and cleaned after a certain period of use. The traditional way of replacing the polishing and grinding roller is more troublesome. When the handle is turned, the bidirectional threaded rod can be driven to rotate, so that the waste chips on the surface of the processing table can be quickly cleaned. When there are enough waste chips in the collection box, they can be processed, which is convenient for the polishing machine to quickly clean the residual waste chips on the surface of the processing table through the scraper during use.

[0003] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, the connection between the polishing roller and the rotating shaft is completed by two L-shaped blocks that can adjust the relative distance and the grooves set on the outer wall of the polishing roller. When the driving device in the polishing machine drives the rotating shaft to rotate at a high speed, it will generate a large torque, and at the same time, it will also generate a large inertia when it stops instantly. Under the condition of high torque and high inertia, the two L-shaped blocks may be deformed. If the L-shaped blocks are deformed or broken, the stability of the polishing roller installation cannot be guaranteed, and the polishing roller is prone to fall off.

Under the condition of high torque and high inertia, the two L-shaped blocks may be deformed.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 7The utility model provides a technical solution: a ceramic polishing machine that is easy to replace the polishing roller, including a polishing machine body 1, a plurality of rotating shafts 2 connected to the output device are rotatably installed on the surface of one side of the polishing machine body 1, a connecting component 3 is fixedly installed at one end of each rotating shaft 2, each connecting component 3 is movably connected to a corresponding polishing member 4, each connecting component 3 includes a connecting seat 301, the connecting seat 301 is fixedly installed at one end of the corresponding rotating shaft 2, and an inwardly recessed connecting slot 302 is opened on the bottom surface of the connecting seat 301 Each polishing member 4 includes a grinding member 401, a connecting shaft 402 is fixedly connected to the middle of one side surface of the grinding member 401, the connecting shaft 402 is inserted into the corresponding connecting slot 302, a plurality of circularly evenly distributed arcuate protrusions 303 are arranged on the inner wall of the connecting slot 302, an arcuate groove 304 corresponding to the arcuate protrusion 303 is arranged on the outer wall of the connecting shaft 402, the arcuate groove 304 is meshed with the arcuate protrusion 303, and a locking connection mechanism and an unlocking mechanism are also arranged in the connecting slot 302

[0025] See also Figures 4 to 7 The snap-fit ​​connection structure includes an insertion rod 306, which is arranged in the connecting slot 302. A plurality of evenly distributed fixing rods 305 are arranged on the circumferential surface of one end of the insertion rod 306. One end of each fixing rod 305 is fixedly connected to the inner wall of the connecting slot 302. A socket 403 corresponding to the insertion rod 306 is provided at the top of the connecting shaft 402. A plurality of slide grooves 307 are evenly arranged on the circumferential side wall of the insertion rod 306 in a ring shape. A slide rod 308 is slidably connected in each slide groove 307. The two ends of a plurality of springs 311 are fixedly connected to the inner wall of one side of the corresponding slide groove 307 on the surface of one side of each slide rod 308. A card block 309 is arranged on the bottom end of the other side surface of each slide rod 308. A plurality of card grooves 310 corresponding to the card blocks 309 are arranged on the circumferential inner wall of the socket 403.

[0026] When the connecting shaft 402 is rotated along the extension direction of the arc groove 304 and the fixing rod 305 and inserted into the connecting slot 302 and installed in place, the positions of the slot 310 and the block 309 correspond, and under the action of the spring 311, the sliding rod 308 slides outward in the sliding groove 307, driving the block 309 to slide into the corresponding slot 310 to complete the engagement, so that the connecting seat 301 as a whole completes the connection with the connecting shaft 402, and the connecting shaft 402 cannot rotate independently relative to the connecting seat 301 or move outward, thereby ensuring the stability of the connection during use.

[0027] Furthermore, the unlocking mechanism includes an unlocking gear 312, which is rotatably connected to the inner wall at the top of the connecting slot 302. A plurality of arc-shaped sliding grooves 313 evenly distributed in a ring shape are provided on the surface of the unlocking gear 312. A connecting rod 314 is slidably connected in each arc-shaped sliding groove 313. One end of each connecting rod 314 is fixedly connected to the surface of one end of the corresponding sliding rod 308. A connecting groove 316 is provided on one side of the unlocking gear 312 on the inner wall of the connecting slot 302. A driving gear 315 is rotatably installed on the inner wall of one side of the connecting groove 316. The driving gear 315 is meshingly connected to the unlocking gear 312.

[0028] When the driving gear 315 is rotated outside the connecting seat 301, the driving gear 315 will drive the unlocking gear 312 to rotate. The two ends of the arc-shaped slide groove 313 on the surface of the unlocking gear 312 have different diameters from the center of the circle. When the unlocking gear 312 rotates, the position of the arc-shaped slide groove 313 changes relatively, thereby squeezing the internal connecting rod 314 to change its position, thereby driving all the sliding rods 308 to slide synchronously in the slide groove 307 through the connecting rod 314, so that all the blocking blocks 309 are synchronously disengaged from the engaging state of the blocking groove 310, and the connecting shaft 402 can be disengaged from the connecting seat 301, completing the overall disassembly of the polishing part 4, and the disassembly process is relatively simple and convenient.

[0029] Furthermore, the unlocking mechanism also includes a limiting stabilization mechanism, which includes a threaded hole 317 opened on the top surface of the connecting seat 301, one end of the threaded hole 317 is connected to the connecting groove 316, and a limiting screw 318 is threadedly connected in the threaded hole 317, and a limiting hole 319 corresponding to the limiting screw 318 is opened on one side surface of the driving gear 315.

[0030] When the connecting shaft 402 and the connecting seat 301 are in a connected state, the limiting screw 318 is rotated to make it move up and down relatively in the threaded hole 317 so that its bottom end can be inserted into the limiting hole 319 set on the surface of the driving gear 315. The driving gear 315 can be limited, which can avoid the situation where the driving gear 315 rotates due to factors such as separation force when the driving device drives the connecting component 3 to rotate as a whole, reducing the stability of the engaging connection mechanism.

[0031] See also Figures 1 to 7 The number of the arc-shaped protrusions 303 and the arc-shaped grooves 304 is at least three.

[0032] When the connecting shaft 402 and the connecting seat 301 are in a connected state, the meshing connection between the arc-shaped protrusions 303 and the arc-shaped grooves 304 can share the high torque generated when the driving device drives the connecting component 3 to rotate as a whole, and as the number of arc-shaped protrusions 303 and arc-shaped grooves 304 increases, the strength against torque becomes higher, thereby improving the stability and service life of the overall connecting structure in long-term, high-torque usage scenarios.

[0033] Furthermore, the rotating shaft 2, the connecting seat 301 and the connecting shaft 402 are coaxially arranged.

[0034] The coaxial arrangement of the rotating shaft 2, the connecting seat 301 and the connecting shaft 402 can ensure the stability of the polishing piece 4 during rotation and the transmission efficiency of the driving device, and avoid the overall shaking of the polishing piece 4 caused by the centrifugal force generated by high-speed rotation.

[0035] Furthermore, the insertion rod 306, the insertion hole 403 and the connecting seat 301 are coaxially arranged.

[0036] The coaxial arrangement of the insertion rod 306, the insertion hole 403 and the connection seat 301 can ensure the stability of the connection structure under high-speed rotation.

[0037] Working principle: When it is necessary to connect the polishing part 4 and the rotating shaft 2, align the arc groove 304 provided on the outer wall of the connecting shaft 402 with the arc protrusion 303 provided on the inner wall of the connecting slot 302, and rotate the connecting shaft 402 in the extending direction to insert it into the connecting slot 302. After installation, the positions of the card slot 310 and the card block 309 correspond. Under the action of the spring 311, the slide bar 308 slides outward in the slide slot 307, driving the card block 309 to slide to the corresponding card slot 310 to complete the engagement, so that the connecting seat 301 as a whole completes the connection with the connecting shaft 402. The connecting shaft 402 cannot rotate independently relative to the connecting seat 301 or move outward, thereby ensuring the stability of the connection during use. At the same time, the limiting screw 318 is rotated so that one end of it is inserted into the limiting hole 319 provided on the surface of the driving gear 315, so as to limit the driving gear 315 and avoid the driving device When driving the connecting assembly 3 to rotate as a whole, the driving gear 315 is affected by factors such as the release force, causing the rotation of the driving gear 315 to reduce the stability of the engaging connection mechanism. When it is necessary to contact the connection between the connecting shaft 402 and the connecting seat 301, when the driving gear 315 is rotated outside the connecting seat 301, the driving gear 315 will drive the unlocking gear 312 to rotate. The two ends of the arc-shaped slide groove 313 on the surface of the unlocking gear 312 have different diameters from the center of its circle. When the unlocking gear 312 rotates, the position of the arc-shaped slide groove 313 changes relatively, thereby squeezing the internal connecting rod 314 to change its position, thereby driving all the sliding rods 308 to slide synchronously in the slide groove 307 through the connecting rod 314, so that all the blocking blocks 309 are synchronously separated from the engaging state with the blocking groove 310, and the connecting shaft 402 can be separated from the connection with the connecting seat 301, completing the overall disassembly action of the polishing part 4, and the disassembly process is relatively simple and convenient.

[0038] It should be noted that the specific model and specifications of the polishing machine body 1 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The power supply and principle of the polishing machine body 1 are clear to those skilled in the art and will not be described in detail here.

[0040] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
