[0003] At present, the temperature of the existing grinding devices used in the production of mechanical tools continues to rise during cutting. In order to avoid the grinding tools being burned, cutting fluid is needed to cool them down. However, as the grinding temperature continues to rise, the cutting fluid will stick to the cutting area, resulting in increased friction between the tool and the iron chips, affecting the processing; in addition, after a long period of grinding, the grinding wheel will cause abrasive particles to fall off, causing local wear of the grinding wheel, resulting in uneven grinding, and increasing the roughness of the processed surface, affecting the grinding of the tool; and when the tool is ground, the metal debris generated adheres to the grinding area of ​​the tool. Even if most of the metal debris can be taken away by the cutting fluid, some metal debris will still remain at the grinding area.

[0029] The specific implementation process is as follows: During the grinding process, the first motor 31 drives the motor shaft 32 to rotate, so that the grinding assembly 4 rotates synchronously to grind the tool. During the rotation of the motor shaft 32, the second synchronous wheel 35 and the reciprocating screw 34 are driven to rotate through the first synchronous wheel 33 and the synchronous belt 36, so that the sliding sleeve 37 and the connecting rod 38 drive the piston plate 39 to move up and down.

At this time, the second connecting pipe 319 and the lower half of the guide pipe 321 are connected, and the upper part of the sealed box 310 is connected to the outside world. A pressure difference will be generated between the lower end of the piston plate 39 and the sealed box 310. By utilizing the generated pressure difference, the water-based cleaning agent inside the second liquid storage tank 318 can only enter the sealed box 310 along the second connecting pipe 319, and then be discharged through the lower half of the guide pipe 321 and the liquid outlet pipe 324 to clean the sticking part of the tool, avoid affecting the normal processing of the tool, and improve the practicality of the device.

[0030] Embodiment 2: The difference from Example 1 is that Figure 6 , Figure 7 , Fig.10 , Fig.11 and Fig.12 As shown, the grinding assembly 4 includes a mounting plate 43 and a plurality of first springs 41, a plurality of blocks 414 are integrally formed at equal intervals on the side wall of the motor shaft 32, a mounting groove 21 is opened at the bottom end of the connecting seat 2, the first springs 41 are fixedly connected to the inner top wall of the mounting groove 21, one end of the first spring 41 is fixedly connected to the top of the mounting plate 43, the mounting plate 43 is slidably matched with the inner wall of the mounting groove 21, and the inner top wall of the mounting groove 21 is symmetrically fixedly connected with a limiting rod 42.

[0031] The limiting rods 42 are all penetrated by the side walls of the mounting plate 43 and are slidably connected. The inner top wall of the mounting groove 21 is fixedly connected with an electromagnet 411. The top of the mounting plate 43 is fixedly connected with a permanent magnet 412. The bottom of the mounting plate 43 is fixedly connected with a second motor 44. The output shaft of the second motor 44 is coaxially fixedly connected with a rotating shaft 45. The side wall of the rotating shaft 45 is fixedly connected with a switching plate 46. The side wall of the switching plate 46 is symmetrically penetrated by a first sleeve 47 and a second sleeve 48 that is rotatably connected.

[0032] The inner walls of the first sleeve 47 and the second sleeve 48 are both provided with a slot 413, the top of the slot 413 and the bottom of the block 414 are both wedge-shaped structures and correspond to each other, the first sleeve 47 and the second sleeve 48 are both slidably matched with the block 414, the side wall of the first sleeve 47 is fixedly connected to the second grinding wheel 410, and the side wall of the second sleeve 48 is fixedly connected to the first grinding wheel 49, so that when the first grinding wheel 49 is damaged, the positions of the first grinding wheel 49 and the second grinding wheel 410 can be effectively swapped, so as to avoid the need to stop the device and replace it after the first grinding wheel 49 is damaged, thereby improving the use effect of the device.

[0033] The specific implementation process is as follows: After a long period of grinding, abrasive particles will fall off the grinding wheel, causing local wear of the grinding wheel, resulting in uneven grinding, increased roughness of the processed surface, and affecting tool grinding. The abrasive grains are located on the rough surface of the grinding wheel side wall, and the filling parts of the first grinding wheel 49 and the second grinding wheel 410 are the abrasive grains. Generally, the first grinding wheel 49 is normally used for tool grinding, and the second grinding wheel 410 is not working and is in a standby state; when the first grinding wheel 49 is used for a long time, abrasive grains fall off, causing uneven grinding of the first grinding wheel 49. At this time, the electromagnet 411 is energized, and the electromagnet 411 generates magnetic poles after being energized. The magnetic repulsion force generated by the same magnetic poles between the electromagnet 411 and the permanent magnet 412 is used to push the mounting plate 43, the second motor 44, the switching plate 46, the first grinding wheel 49 and the second grinding wheel 410 to move downward synchronously. At this time, the first spring 41 is in a stretched state, wherein the first grinding wheel 49 is clamped with the motor shaft 32 through the second sleeve 48, so that when the electromagnet 411 is energized, the first grinding wheel 49 begins to separate from the motor shaft 32;

[0034] When the first grinding wheel 49 is completely separated from the motor shaft 32, the second motor 44 starts to work, driving the rotating shaft 45 to rotate 180 degrees, replacing the first grinding wheel 49 and the second grinding wheel 410, so that the second grinding wheel 410 is concentrically arranged with the motor shaft 32, and then the electromagnet 411 is powered off, so that the magnetism between the electromagnet 411 and the permanent magnet 412 is lost, and then under the elastic action of the first spring 41, the mounting plate 43, the second motor 44, the switching plate 46, the first grinding wheel 49 and the second grinding wheel 410 are driven to move up and reset. During the upward movement, the second grinding wheel 410 is clamped with the motor shaft 32. The top ends of the card slots 413 inside the first sleeve 47 and the second sleeve 48 are both wedge-shaped structures, and the bottom ends of the card blocks 414 on the side walls of the motor shaft 32 are also wedge-shaped structures, so that they can be effectively connected, so that the first grinding wheel 49 or the second grinding wheel 410 rotates synchronously with the motor shaft 32, wherein the elastic force of the first spring 41 is greater than the sum of the gravity below the mounting plate 43; by providing the second grinding wheel 410, when the first grinding wheel 49 is damaged, the positions of the first grinding wheel 49 and the second grinding wheel 410 can be effectively swapped, so as to avoid the need to stop the device and then replace it after the first grinding wheel 49 is damaged, thereby improving the use effect of the device.

[0035] Embodiment 3: The difference from Example 2 is that Fig.13 , Fig.14 and Fig.15As shown, the chip removal assembly 5 includes a fixed plate 51, which is fixedly connected to the side wall of the motor shaft 32. A plurality of slide grooves 52 are provided at equal angles at the bottom end of the fixed plate 51. The inner walls of the slide grooves 52 are embedded with strong magnets 56 that slide with the slide grooves 52. A plurality of first rotating rods 53 are rotatably connected to the side wall of the motor shaft 32 at equal angles. A second rotating rod 54 is hinged at one end of the first rotating rod 53. One end of the second rotating rod 54 is rotatably matched with the side wall of the adjacent strong magnet 56.

[0036] The side walls of the first rotating rod 53 are fixedly connected with the second spring 55, one end of the second spring 55 is fixedly connected to the side wall of the adjacent second rotating rod 54, the side walls of the motor shaft 32 are fixedly connected with the scraper 57, the bottom ends of the strong magnets 56 are in contact with the side walls of the scraper 57, the side walls of the motor shaft 32 are fixedly connected with the collecting box 58, and the collecting box 58 is located below the scraper 57.

[0037] The specific implementation process is as follows: Since the metal debris generated during tool grinding will adhere to the tool grinding area, and even if most of the metal debris can be taken away by the cutting fluid, some metal debris will still remain at the grinding site. If it is not cleaned in time and enters the grinding position, after high-temperature grinding, it will aggravate the wear and breakage of the tool. Furthermore, when the tool is being ground, the motor shaft 32 rotates at a relatively fast speed, and the centrifugal force generated by the motor shaft 32 is used to drive multiple strong magnets 56 to move along the slide groove 52 toward the outer ring. At this time, the second spring 55 is in a stretched state. During the grinding operation, the elastic force of the second spring 55 is less than the centrifugal force generated by the rotation of the motor shaft 32. When the strong magnet 56 moves to the limit, it rotates synchronously with the motor shaft 32, so that the first grinding wheel 49 can rotate synchronously through the strong magnet 56 above it during the rotation process, and absorb the remaining metal debris to prevent the remaining metal debris from entering the grinding area and affecting the tool quality; when the tool is ground, the second spring 55 is in a stretched state. When switching or adjusting the position of the first grinding wheel 49, the rotation speed of the motor shaft 32 will decrease accordingly, and the centrifugal force generated at this time will become smaller. At this time, under the elastic action of the second spring 55, the first rotating rod 53 and the second rotating rod 54 are driven to rotate and contract, pulling the strong magnet 56 back to the motor shaft 32. The side walls of the strong magnet 56 are provided with magnetic isolation strips for isolating the magnetic attraction generated by the strong magnet 56 on the surroundings, so that it can only magnetically adsorb the grinding area directly below. In the process of the strong magnet 56 approaching the motor shaft 32, the scraper 57 is used to scrape off the metal debris adsorbed on the bottom of each strong magnet 56, so that the metal debris falls into the collection box 58.

[0038] Among them, the inside of the collection box 58 is provided with a sticky material with strong viscosity, which can effectively wrap and stick the metal debris to prevent the metal debris from being thrown out under the centrifugal action, and when grinding again later, after the speed of the motor shaft 32 increases, the strong magnet 56 will bring out the metal debris inside the collection box 58 again when it leaves, causing an impact. The port of the collection box 58 is slightly lower than the bottom end of the scraper 57, so that the strong magnet 56 will only contact the top of the scraper 57 during the movement, and will not contact the port of the collection box 58, avoiding the limiting effect.

[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
