The bottom end of the collecting frame 33 is communicated with a water delivery pipe, so that the debris can be effectively collected after being discharged into the collecting frame 33, and the cooling liquid can be timely transferred after being discharged into the collecting frame 33. The rectangular frame 31, the driving assembly 32 and the collecting frame 33 together constitute a fixing mechanism 3 for providing a working space for polishing workpieces.

[0067] As Figures 2-3 The left and right sides of the processing table 4 are movably provided with cleaning mechanisms 5. By the design of the cleaning mechanisms 5, the debris discharged from the processing table 4 can be collected, and the debris can be effectively and simply discharged outside the rectangular frame 31 in time. Figure 15The side wall of the cleaning frame 51 close to the processing table 4 is provided with a cleaning cavity, and the cleaning cavity of the cleaning frame 51 is communicated with the transverse groove of the processing table 4. When the debris is discharged from the transverse groove of the processing table 4, it can be collected by the cleaning cavity of the cleaning frame 51, avoiding the debris from falling on the rectangular frame 31 to increase the difficulty of cleaning the debris in the rectangular frame 31. The bottom end of the cleaning frame 51 is provided with a filter hole, and the filter hole is communicated with the cleaning cavity. The aperture of the filter hole is smaller than the size of the debris, which can effectively filter the cooling liquid carrying the debris, so that the debris remains in the cleaning frame 51, and the cooling liquid is discharged downward.

The front and rear side walls of the cleaning plate 52 are fixedly provided with bristles, and the bristles are inclined downward. The bristles on the adjacent cleaning plates 52 are in contact with each other. When the cleaning mechanism 5 reciprocates in the rectangular frame 31, the cleaning plate 52 and the bristles thereon are used to effectively sweep the debris into the collecting frame 33, realize the cleanliness of the inner bottom end of the rectangular frame 31, and ensure the smoothness of the movement of the processing table 4. In addition, since the cleaning plate 52 and the bristles are arranged below the cleaning frame 51, the downward discharge of the cooling liquid can effectively flush the cleaning plate 52 and the bristles, realize the full cleaning of the cleaning plate 52 and the bristles, prevent the accumulation of debris in the cleaning plate 52 and the bristles from affecting the subsequent cleaning effect, and improve the service life of the cleaning plate 52.

The top end of the machining table 4 is provided with a limiting long groove, and the machining table 4 is movably connected with the limiting plate through the limiting long groove. When the limiting block 71 is installed in the limiting short groove, if the limiting block 71 generates magnetic repulsion on the limiting plate, the movable long plate 81 can be pushed to move to the workpiece direction, so as to abut against the side wall of the workpiece, and the clamping stability of the workpiece is enhanced. If the limiting block 71 generates magnetic attraction on the limiting plate, the clamping effect on the workpiece is abandoned, so that the workpiece is convenient to disassemble. The bottom end of the movable long plate 81 corresponding to the position of the inclined groove is provided with a rectangular groove, and the bottom end of the movable long plate 81 is movably connected with the top end of a movable shell 82 through the rectangular groove. The bottom surface of the movable shell 82 is adapted to the inclined groove of the machining table 4, and the lower half of the movable shell 82 is fixedly sleeved with a check valve. The check valve is located on the side wall of the movable shell 82 away from the horizontal groove, and a filter screen is arranged on the check valve. The check valve can effectively filter the debris. When the cooling liquid moves in the inclined groove, the check valve can receive the cooling liquid, so that the cooling liquid enters the movable shell 82 through the check valve and is stored in the movable shell 82. The movable part 83 is composed of a bottom plate and a top rod. The four corners of the top end of the bottom plate are fixedly connected with the movable part 83. The bottom plate is arranged at the bottom end of the movable shell 82, and the top rod surrounds the movable shell 82, so that the movable part 83 can effectively support and protect the movable shell 82. The bottom end of the movable long plate 81 corresponding to the position of the inclined groove is provided with a cylindrical groove, and the bottom end of the movable long plate 81 is movably connected with the top end of the movable part 83 through the cylindrical groove. The top end of the movable part 83 has magnetism. If the movable part 83 is subjected to magnetic attraction, the movable part 83 can drive the movable shell 82 to move upward together, so as to effectively extrude the cooling liquid stored in the movable shell 82. The inside of the movable long plate 81 is fixedly sleeved with a movable strip 84, and the movable strip 84 is located at the top end of the cylindrical groove of the movable long plate 81. The movable strip 84 is an energized magnet, and the energization has magnetism opposite to that of the movable part 83. The magnetic attraction between the movable strip 84 and the movable part 83 can provide power for the upward movement of the movable part 83. The inside of the movable long plate 81 corresponding to the position of the inclined groove is fixedly sleeved with a water spraying part 85, and one end of the water spraying part 85 is communicated with the inside of the movable shell 82. The other end of the water spraying part 85 faces the workpiece. When the movable shell 82 moves upward, the bottom end of the movable long plate 81 will extrude the internal space of the movable shell 82, so that the cooling liquid in the movable shell 82 is discharged through the water spraying part 85, and the side surface of the workpiece is sprayed, which can not only sufficiently cool the side surface of the workpiece and reduce local overheating, but also enhance the cleaning effect of the grinding wheel assembly 25 and the side surface of the workpiece, and further improve the secondary utilization rate of the cooling liquid. In addition, when the movable shell 82 and the movable part 83 move upward without being subjected to magnetic attraction, they are always adapted to the inclined groove of the machining table 4, so that when the workpiece is not machined, the movable assembly 8 can effectively clean the top end of the machining table 4 by moving on the machining table 4, and the debris in the machining table 4 can be simply and timely discharged, so as to prevent the debris from continuously accumulating in the machining table 4 and affecting the working environment.Improve processing quality and efficiency.

[0072] As Figure 13 、 Figure 15 Two limiting films 72 are arranged in the limiting long groove of the processing table 4, and one end of the limiting film 72 is connected with the limiting plate of the movable long plate 81, and the other end of the limiting film 72 is connected with the end sidewall of the limiting long groove, so that the limiting film 72 effectively covers the top end of the limiting long groove, preventing debris from entering and affecting use.

[0073] The working principle of the use method of the present application is as follows:

[0074] When the workpiece needs to be polished, first place the workpiece on the top end of the processing table 4, then use the clamping plate 61 to control the clamping piece 62 to clamp the left and right sides of the workpiece, use the limiting block 71 to control the movable assembly 8 to resist the front and back sides of the workpiece, then start the vertical feeding assembly 22 to make the grinding wheel assembly 25 vertically descend, start the longitudinal feeding assembly 24 to make the grinding wheel assembly 25 longitudinally translate, so as to realize the contact between the grinding wheel assembly 25 and the workpiece, then start the grinding wheel assembly 25 to polish the workpiece, in this process, the spraying assembly 26 continuously sprays cooling liquid to the contact point between the grinding wheel assembly 25 and the workpiece, realizing cooling and lubrication of the workpiece, in addition, according to actual needs, start the driving assembly 32 and drive the processing table 4 to move horizontally inside the rectangular frame 31.

[0075] When the workpiece is processed, part of the debris will fall to the top end of the processing table 4, because the cooling liquid flows on the top end of the processing table 4, and because of the design of the inclined groove and the horizontal groove on the top end of the processing table 4, the cooling liquid can carry the debris to move along the inclined groove first, then along the horizontal groove, until it is discharged from the processing table 4 and discharged into the cleaning frame 51, effectively realizing simple and timely discharge and collection of the debris in the processing table 4, thereby preventing the debris from continuously accumulating in the processing table 4 and affecting the working environment, improving the processing quality and efficiency, in addition, under the action of the inclined groove and the horizontal groove of the processing table 4, the moving path of the cooling liquid is effectively limited, so that the bottom end of the workpiece is continuously in contact with the flowing cooling liquid during the processing process, not only effectively cooling the bottom surface of the workpiece, but also improving the secondary utilization rate of the cooling liquid.

[0076] When the workpiece is processed, part of the debris will fall to the inside bottom end of the rectangular frame 31, because the driving assembly 32 controls the movement of the processing table 4, so that the cleaning plate 52 and the bristles thereon effectively clean the inside bottom end of the rectangular frame 31, so that the debris in the rectangular frame 31 can be discharged into the collection frame 33, effectively realizing simple and timely discharge and collection of the debris in the rectangular frame 31, preventing the debris from continuously accumulating in the rectangular frame 31 and affecting the working environment, improving the processing quality and efficiency.

[0077] In the process of machining the workpiece, the cooling liquid is sprayed by the spraying assembly 26, moves to the collecting frame 33 through the machining table 4, the rectangular frame 31 and the like, and is finally discharged from the surface grinder. In the process, part of the cooling liquid is discharged downward through the filter holes of the cleaning frame 51, effectively flushes and cleans the cleaning plate 52 and the bristles thereof, prevents the cleaning plate 52 and the bristles thereof from storing debris to affect the subsequent cleaning effect, and improves the service life of the cleaning plate 52.

[0078] When the workpiece is machined, the movable long plate 81 is abutted against the workpiece under the magnetic repulsion of the limiting block 71. In the process, when the movable strip 84 is not electrified, the movable shell 82 and the movable piece 83 are lowered into the chute of the machining table 4 under the gravity of the movable shell 82 and the movable piece 83 themselves, and are adapted to the size of the chute. At this time, the cooling liquid can enter and be stored in the movable shell 82 through the one-way valve. When the movable strip 84 is electrified, the magnetic attraction of the movable strip 84 to the movable piece 83 makes the movable piece 83 move upward, synchronously drives the movable shell 82 to move upward, and makes the internal space of the movable shell 82 be compressed by the bottom end of the movable long plate 81, effectively extruding the cooling liquid to make it be discharged to the workpiece through the water spraying piece 85, effectively spraying the side surface of the workpiece, thereby not only being capable of sufficiently cooling the side surface of the workpiece and reducing local overheating, but also being capable of enhancing the cleaning effect of the grinding wheel assembly 25 and the side surface of the workpiece, and further being capable of further improving the secondary utilization rate of the cooling liquid. When the workpiece is not machined, if the movable strip 84 is not electrified and moves in the horizontal groove direction on the machining table 4, the top end and the chute of the machining table 4 are effectively cleaned, so that the residual debris is discharged into the horizontal groove, and finally is uniformly discharged into the cleaning frame 51 through the horizontal groove, further realizing that the debris in the machining table 4 is simply and timely discharged, preventing the debris from continuously accumulating in the machining table 4 to affect the working environment, and improving the machining quality and efficiency.
