The impact force of the airflow drives the shaft 14 to rotate, thereby causing the blades 15 to rotate. The airflow can be broken up and dispersed by the rotation of the blades 15 to increase the dispersion area of ​​the airflow, thereby blowing away the iron filings remaining on the surface of the crankshaft. In this process, a large amount of iron filings generated during the machining and grinding of the crankshaft can be reduced, resulting in the iron filings easily remaining on the surface of the crankshaft, making it difficult to clean them, thereby affecting the grinding effect of the crankshaft. At this time, the airflow generated by the rotation of the fan blades 12 can clean the iron filings generated during the grinding of the crankshaft. At the same time, the blowing range of the fan blades 12 can be increased by the blades 15 to improve the cleaning effect.

[0025] like Figure 2-5 As shown, the inner side wall of the CNC crankshaft grinder body 1 is fixedly connected to a guide rail 2; the side wall of the guide rail 2 is evenly provided with a plurality of slots 21; the inner side wall of the guide rail 2 is slidably connected to a slider 22; the side wall of the slider 22 is hinged with a clamping block 23; when in use, the clamping block 23 is first held and pulled, and when it is pulled apart, a certain force is applied to the drive motor 11, and at this time, under the sliding cooperation between the guide rail 2 and the slider 22, the slider 22 will slide on the inner side wall of the guide rail 2, and the position of the drive motor 11 is adjusted. When adjusted to a suitable position, the clamping block 23 will engage with one of the slots 21. The position corresponds to that of the locking block 23. At this time, the locking block 23 is released. Under the action of the internal torsion spring at the hinge of the locking block 23, it can be automatically reset, so that it can be inserted into the locking slot 21 to fix the slider 22, thereby completing the adjustment of the position of the drive motor 11. In this process, the need for the staff to adjust the position of the drive motor 11 can be reduced, which makes it difficult to adjust the drive motor 11, causing the adjustment process to be more cumbersome, thereby increasing a certain amount of workload. At this time, the guide rail 2 is set to facilitate the adjustment of the drive motor 11 and improve the flexibility of the drive motor 11 when in use.

[0026] like Figure 3 , 4As shown, the side wall of the slider 22 is provided with a through hole 3; the side wall of the slider 22 is fixedly connected with a support plate 31; the side wall of the support plate 31 is fixedly connected with a spring 32; the end of the spring 32 is fixedly connected with an insert block 33; the side wall of the insert block 33 is fixedly connected with a pull plate 34; the pull plate 34 penetrates the wall of the support plate 31 and is slidably connected thereto; the side wall of the drive motor 11 is fixedly connected with a mounting block 35; the mounting block 35 is slidably matched with the through hole 3; the side wall of the mounting block 35 is provided with a slot 36; when in use, the staff first applies a certain force to the pull plate 34, pulls the insert block 33 to a certain extent, and then holds the drive motor 11 Reach 11, insert the mounting block 35 into the side wall of the through hole 3, when the mounting block 35 is inserted to the appropriate position, the slot 36 will correspond to the position of the plug block 33, and then release the pull plate 34, at this time it will automatically reset under the elastic force of the spring 32, thereby pushing the plug block 33 into the slot 36 and making it stuck, so that the drive motor 11 can be fixed. In this process, the drive motor 11 can be reduced. When it is damaged after long-term use, it is inconvenient to disassemble it, thereby increasing a certain amount of workload. At this time, the mounting block 35 is inserted into the through hole 3 for fixing, thereby facilitating the disassembly and maintenance of the drive motor 11.

[0027] like Figure 3 , 4 As shown, a pair of elastic plates 4 are fixedly connected to the side walls of the slider 22; the elastic plates 4 are symmetrically arranged on both sides of the slider 22 and have the same structure; the side walls of the elastic plates 4 are fixedly connected to the elastic rods 41; the elastic rods 41 are fixedly connected to the slider 22; when in use, when the mounting block 35 is inserted into the side walls of the through hole 3, the mounting block 35 will contact and squeeze the elastic plates 4 on both sides, and by squeezing the elastic plates 4, a certain deformation can be generated between the elastic plates 4 and the elastic rods 41, and then a reaction force will be applied to the mounting block 35 under the elastic force of the elastic plate 4, pushing the mounting block 35 to the middle of the through hole 3, so that the positions of the two are aligned, and at the same time, the mounting block When the mounting block 35 is inserted, the mounting block 35 will also slide toward the middle of the elastic plates 4 on both sides. Later, when the mounting block 35 is staggered with the elastic plates 4, the elastic force of the elastic rods 41 can quickly reset the elastic plates 4, thereby reducing the occurrence of the elastic plates 4 being difficult to recover after being hit and squeezed. In this process, it can reduce the difficulty in aligning the positions of the two when the mounting block 35 is inserted into the side wall of the through hole 3, making the insertion process more cumbersome, thereby increasing a certain amount of workload. At this time, the elastic plates 4 are set to play a role of limiting the insertion of the mounting block 35 into the through hole 3, and at the same time, the elastic rods 41 can play a role of preventing the elastic plate 4 from deforming.

[0028] like Figure 5As shown, a pair of spring rods 5 are fixedly connected to the side walls of the slider 22; the spring rods 5 are symmetrically arranged on both sides of the slider 22 and have the same structure; a shovel plate 51 is fixedly connected to the end of the spring rod 5; when in use, when the slider 22 is moving, the shovel plate 51 contacts the inner wall of the guide rail 2, so that the iron filings dropped on the inner wall of the guide rail 2 can be shoveled away, so that they do not enter between the slider 22 and the guide rail 2, and at the same time, when the shovel plate 51 contacts the guide rail 2, a certain friction force will be generated, causing wear on the shovel plate 51, so that the distance between the shovel plate 51 and the guide rail 2 is increased. The elastic force of the spring rod 5 will exert a certain reaction force on the shovel plate 51, so that the shovel plate 51 is always in full contact with the inner wall of the guide rail 2. In this process, some iron filings generated during crankshaft grinding can be reduced from entering the guide rail 2, causing them to be blocked between the guide rail 2 and the slider 22, thereby affecting the sliding effect of the slider 22 on the inner wall of the guide rail 2. At this time, the shovel plate 51 is pushed away, thereby playing a role in cleaning the iron filings that fall into the guide rail 2, thereby improving the sliding effect of the slider 22, and at the same time, the spring rod 5 can increase the full contact between the shovel plate 51 and the inner wall of the guide rail 2.

[0029] like Figure 5 As shown, the side wall of the card block 23 is fixedly connected with a buckle plate 6; the side wall of the buckle plate 6 is evenly fixedly connected with a plurality of rubber strips 61; when in use, the staff places the finger on the side wall of the buckle plate 6, and the finger can be hooked under the arc action of the buckle plate 6, and then a certain pulling force is applied to the buckle plate 6, so that the card block 23 can be pulled open, and at the same time, when the buckle plate 6 is pulled, the surface of the finger will fully contact with the rubber strip 61 and generate a certain friction force. In this process, the staff can reduce the need to pull the card block 23 open, which makes it inconvenient to hold the card block 23, causing it to easily slip off the side wall of the card block 23 when pulling. At this time, the buckle plate 6 and the rubber strip 61 are set, so as to facilitate the card block 23 when being pulled open, and improve the firmness between the hand and the card block 23.

[0030] like Figure 4 As shown, a plurality of sponge blocks 7 are evenly fixed to the side wall of the elastic plate 4; when in use, when the mounting block 35 is inserted into the through hole 3, it will touch the elastic plate 4. At this time, the sponge block 7 can block the direct contact between the two, thereby reducing the collision force generated by the mounting block 35 on the elastic plate 4. In this process, the mounting block 35 can be reduced from hitting the elastic plate 4 when inserted into the through hole 3, which may cause certain damage to the elastic plate 4, causing deformation and making it difficult to reset, thereby affecting the use effect of the elastic plate 4. At this time, the sponge block 7 is provided to play a protective buffering role when the mounting block 35 hits the elastic plate 4, thereby increasing the service life of the elastic plate 4.

[0031] During operation, when the crankshaft is ground by the CNC crankshaft grinder body 1, the drive motor 11 is started at the same time, and the drive motor 11 can drive the fan blade 12 to rotate. The rotation of the fan blade 12 will generate airflow to blow air to the surface of the crankshaft. At the same time, the airflow will contact the blade 15, and the impact force of the airflow will drive the rotating shaft 14 to rotate, thereby rotating the blade 15. The airflow can be broken up and dispersed by the rotation of the blade 15 to increase the dispersion area of ​​the airflow, thereby blowing off the iron filings remaining on the surface of the crankshaft. When in use, first hold the clamping block 23 and pull it. After pulling it open, a certain force is applied to the drive motor 11. At this time, under the sliding cooperation between the guide rail 2 and the slider 22, the slider 22 will slide on the inner wall of the guide rail 2, and the drive The position of the motor 11 is adjusted. When it is adjusted to a suitable position, the block 23 will correspond to the position of one of the slots 21. At this time, the block 23 is released. Under the action of the internal torsion spring at the hinge of the block 23, it can be automatically reset, so that it is inserted into the slot 21 and the slider 22 is fixed, thereby completing the adjustment of the position of the drive motor 11. When in use, the staff first applies a certain force to the pull plate 34 to pull the plug 33 to a certain extent, and then holds the drive motor 11 to insert the mounting block 35 into the side wall of the through hole 3. When the mounting block 35 is inserted to a suitable position, the slot 36 will correspond to the position of the plug 33, and then the pull plate 34 is released. At this time, it will automatically reset under the elastic force of the spring 32, thereby The insert block 33 is pushed into the slot 36 to make it stuck, so that the drive motor 11 can be fixed. When in use, when the mounting block 35 is inserted into the side wall of the through hole 3, the mounting block 35 will contact and squeeze the elastic plates 4 on both sides. By squeezing the elastic plates 4, a certain deformation can be generated between the elastic plates 4 and the elastic rods 41. Then, under the elastic force of the elastic plates 4, a reaction force is applied to the mounting block 35, and the mounting block 35 is pushed to the middle of the through hole 3 to align the positions of the two. At the same time, when the mounting block 35 is inserted, the mounting block 35 will also slide toward the middle of the elastic plates 4 on both sides. Then, when the mounting block 35 is staggered with the elastic plates 4, the elastic force of the elastic rods 41 can quickly reset the elastic plates 4, reducing the situation where the elastic plates 4 are difficult to recover after being collided and squeezed. When the slider 22 is in use, the scraper plate 51 contacts the inner wall of the guide rail 2, and the iron filings dropped on the inner wall of the guide rail 2 can be scraped off, so that the iron filings do not enter between the slider 22 and the guide rail 2. At the same time, when the scraper plate 51 contacts the guide rail 2, a certain friction force will be generated, which will cause wear on the scraper plate 51 and increase the distance between the scraper plate 51 and the guide rail 2. At this time, under the elastic force of the spring rod 5, a certain reaction force will be applied to the scraper plate 51, so that the scraper plate 51 is always in full contact with the inner wall of the guide rail 2. When in use, the staff can place their fingers on the side wall of the pinch plate 6, and the fingers can be hooked under the arc action of the pinch plate 6, and then a certain pulling force is applied to the pinch plate 6, so that the block 23 can be pulled open. At the same time, when the pinch plate 6 is pulled,The surface of the finger will fully contact the rubber strip 61 and generate a certain friction force. When the mounting block 35 is inserted into the through hole 3, it will touch the elastic plate 4. At this time, the sponge block 7 can block the direct contact between the two, reducing the collision force generated by the mounting block 35 on the elastic plate 4.
