The movement of the sliding plate drives the telescopic clamping plate to move, and the movement of the telescopic clamping plate drives the baffle plate to move. The receiving rod moves downward and squeezes the processing box to tilt towards the end close to the receiving rod. At the same time, the first L-shaped plate and the second L-shaped plate move towards the middle and drive the push rod to move closer inward. At the same time, without the limit of the T-shaped convex plate, the telescopic push rod moves towards the direction close to the receiving rod, pushing the debris and water that have been pushed towards the middle by the push rod towards the guide plate. The debris and water slide along the guide plate towards the direction of the waste drawer, keeping the workbench surface clean. At the same time, the clean workbench surface can prevent waste, debris, etc. from contaminating the surface of the workpiece, ensuring the quality of the workpiece after grinding.

During the grinding process, water is dripped for cooling, which can effectively reduce the temperature of the workpiece and the grinding tool, prevent the workpiece from deforming due to overheating or the grinding tool from wearing out quickly, and moreover, an appropriate amount of water can reduce the flying of dust and metal chips and keep the working environment clean.

[0022] A spring 34 is arranged between the fixing ring 35 and the grinding cylinder 32. A semi-circular opening is provided at the top of the grinding cylinder 32, and a first chute is provided on the surface of the workbench 11. When the spring 34 moves upward, it squeezes the fixing ring 35 to move upward, and at the same time, through the reaction force, the grinding cylinder 32 pushes the fixing rod 36 to move upward.

[0023] The fixing rod 36 is fixedly penetrated through the fixing ring 35, the fixing rod 36 is fixedly connected to the pressing ring 37, and there is a protrusion at the bottom of the pressing ring 37 for blocking the water outlet of the water tank 38. When the pressing ring 37 moves upward, the limit on the water outlet of the water tank 38 is released.

The pressing ring 37 moves upward under the action of the fixing rod 36. At the same time, the upward movement of the pressing ring 37 releases the limit on the water outlet of the water tank 38. Without the restriction of the pressing ring 37, the water inside the water tank 38 flows through the water outlet into the water pipe 39 and then through the water pipe 39 into the grinding cylinder, cleaning the flying chips generated during the grinding process. It can accurately spray water on the grinding part, effectively reduce the consumption of water, save resources, meet the environmental protection requirements. And during the grinding process, due to friction, a large amount of heat will be generated. Dripping water can effectively reduce the temperature of the workpiece and the grinding tool, prevent the workpiece from deforming due to overheating or the grinding tool from wearing out quickly. Moreover, an appropriate amount of moisture can reduce the flying of dust and metal chips, keep the working environment clean, thereby enhancing the grinding accuracy and ensuring the surface quality.

[0025] Please refer to Figures 1-9 , on the basis of the above embodiment, in another embodiment of the present invention, it further includes a clamping device and a cleaning device.

The free end of the telescopic elastic rod one 48 is fixedly installed on the circumferential surface of the telescopic clamping rod 47. The second fixing plate 49 is fixedly installed on the inner wall of the telescopic clamping plate 45. Since the telescopic clamping rod 47 is slidably connected to the telescopic clamping plate 45, when grinding the material, the telescopic clamping rod 47 will adaptively slide downward according to the grinding force, maintaining the stability of the material during the grinding process.

[0026] A first tooth block is provided at the output end of the second motor 41. A second tooth block is provided on the surface of the L-shaped plate one 42. A third tooth block is provided on the surface of the L-shaped plate two 43. And the second tooth block provided on the surface of the L-shaped plate one 42 meshes with the first tooth block provided at the output end of the second motor 41. The output end of the second motor 41 rotates to drive the L-shaped plate one 42 to move towards the L-shaped plate two 43, and at the same time, the output end of the second motor 41 rotates to drive the L-shaped plate two 43 to move towards the L-shaped plate one 42.

[0027] The L-shaped plate one 42 is fixedly penetrated through the sliding plate 44, and the L-shaped plate two 43 is fixedly penetrated through the sliding plate 44. The telescopic elastic rod one 48 is fixedly connected to the fixing plate two 49. At the same time, the telescopic elastic rod one 48 supports the telescopic clamping rod 47 under the support of the fixing plate two 49, so that the telescopic clamping rod 47 is not prone to vibration during its grinding process.

[0028] The cleaning device includes a connecting rod 51, a processing box 52, a push rod 53, a T-shaped convex plate 54, a telescopic push rod 55, a receiving rod 56, a guide plate 57, a waste box 58 and a handle 59. The connecting rod 51 is fixedly installed at the bottom of the workbench 11, the processing box 52 is fixedly installed on the surface of the connecting rod 51, the push rod 53 is fixedly installed on the circumferential surface of the L-shaped plate one 42. A T-shaped groove is formed in the inner wall of the processing box 52, and the T-shaped convex plate 54 is slidably installed on the inner wall of the T-shaped groove.

The guide plate 57 is fixedly penetrated through the surface of the waste drawer 13. The handle 59 is fixedly installed on the surface of the waste box 58. The debris and water that have been pushed towards the middle by the push rod 53 are pushed towards the guide plate 57, and the debris and water slide along the guide plate 57 towards the waste drawer 13 and then fall into the waste box 58.

[0029] The push rod 53 slides on the surface of the processing box 52, and the push rod 53 slides through the surface of the connecting rod 51. An outlet is formed on the surface of the waste box 58. The guide plate 57 is fixedly penetrated through the waste box 58. The upper part of the receiving rod 56 is provided with an inclined plane. The receiving rod 56 moves downward and squeezes the processing box 52 to tilt towards the end close to the receiving rod 56. At the same time, the L-shaped plate one 42 and the L-shaped plate two 43 move towards the middle and drive the push rod 53 to move closer inward.

[0030] During the operation of this embodiment: Start the second motor 41. The rotation of the output end of the second motor 41 drives the first L-shaped plate 42 to move towards the second L-shaped plate 43, and at the same time, the rotation of the output end of the second motor 41 drives the second L-shaped plate 43 to move towards the first L-shaped plate 42. The first L-shaped plate 42 and the second L-shaped plate 43 respectively drive the sliding plate 44 to move. The movement of the sliding plate 44 drives the telescopic clamping plate 45 to move. At the same time, the movement of the telescopic clamping plate 45 drives the baffle 46 to move. The movement of the baffle 46 pushes the debris scattered on the workbench 11 down, and it falls through the material opening provided on the workbench 11. When the sliding plate 44 moves to clamp and fix the material, the first motor 31 is started, and the grinding cylinder 32 starts to rotate and grind the material. Since the telescopic clamping rod 47 is slidably connected to the telescopic clamping plate 45, the telescopic clamping rod 47 will slide downward adaptively according to the grinding force during the grinding of the material, maintaining the stability of the material during the grinding process, and further improving the grinding accuracy during the clamping process. At the same time, the first telescopic elastic rod 48 supports the telescopic clamping rod 47 under the support of the second fixing plate 49, so that the telescopic clamping rod 47 is not easily vibrated during the grinding process, and the machining error caused by vibration and displacement of the workpiece during the grinding process can be reduced during strengthening fixation, thereby improving the grinding accuracy and surface quality. At the same time, fixing the workpiece well can reduce the possibility of accidents for the operator during the grinding process, such as injuries caused by the sudden slipping or movement of the workpiece, thereby enhancing work safety. Through the support of the fixing device, it is possible to avoid scratches and collisions caused by the instability of the workpiece during grinding, reduce the risk of workpiece damage, and maintain the integrity of the workpiece.

[0031] The sliding plate 44 moves towards the middle. The movement of the sliding plate 44 drives the telescopic clamping plate 45 to move. The movement of the telescopic clamping plate 45 drives the baffle plate 46 to move. The baffle plate 46 moves to contact and squeeze the receiving rod 56. The receiving rod 56 moves downward under its reaction force. The receiving rod 56 moves downward and squeezes the processing box 52 to tilt towards the end close to the receiving rod 56. At the same time, the first L-shaped plate 42 and the second L-shaped plate 43 move towards the middle and drive the push rod 53 to move closer inward. The push rod 53 moves to push the debris and water on the surface of the processing box 52 towards the middle. The push rod 53 moves to contact and squeeze both ends of the T-shaped convex plate 54. Under the extrusion of the push rod 53, the T-shaped convex plate 54 moves downward. The downward movement of the T-shaped convex plate 54 releases the limit on the telescopic push rod 55. At the same time, without the limit of the T-shaped convex plate 54, the telescopic push rod 55 moves towards the direction close to the receiving rod 56, and pushes the debris and water that have been pushed towards the middle by the push rod 53 towards the guide plate 57. The debris and water slide along the guide plate 57 towards the direction of the waste drawer 13 and then fall into the waste box 58. Subsequently, the operator pulls out the waste box 58 through the handle 59 and pours out the waste and water. This keeps the workbench 11 clean. At the same time, the clean workbench 11 can prevent waste, debris, etc. from contaminating the surface of the workpiece, ensuring the quality of the polished workpiece. Regularly cleaning and collecting waste can reduce the wear of the equipment, lower the frequency of maintenance and replacement of parts, save costs. The cleaning and collecting device can process waste in real time, reduce the time for workers to clean the environment, improve the overall production efficiency, and timely cleaning of waste can reduce the accumulation in the equipment, lower the equipment failure rate, and improve the working efficiency and service life of the equipment.
