Description

Technical Field

[0001] The present invention relates to the technical field of electric saw accessories, and particularly relates to a multifunctional saw blade grinding and polishing device. Background Art

[0002] An electric reciprocating saw, also known as a reciprocating electric saw, is an electric tool that drives a saw blade to move reciprocally through a motor for sawing. It imitates the user's up-and-down movement of the saw blade during cutting, making it faster and more labor-saving for the user to cut materials. When the saw teeth of an electric saw blade are stored for a long time without protective measures, rust spots and rust will appear on its surface, which will affect the movement of the saw blade. Therefore, it is necessary to polish the surface of the electric saw blade before use.

[0003] Currently, when grinding an electric saw blade, a simple grinding device is often used for manual grinding, or a special electric saw blade grinder is used to remove rust from the surface of the saw blade. However, no matter which grinding method is used, it is necessary to manually hold the grinding instrument for polishing operation. During the grinding process, not only the grinding angle and direction need to be determined, but also the electric saw blade grinder needs to be held firmly to maintain a moderate angle and strength to avoid excessive wear. In addition, protective gear needs to be worn and attention needs to be paid to avoiding saw teeth and debris at all times. As a result, the actual operation difficulty and complexity are relatively high. Therefore, a multifunctional saw blade grinding and polishing device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that when grinding an electric saw blade, it is often necessary to manually hold a grinding instrument for polishing operation.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By providing a grinding assembly in the present invention, when rotating the two steering plates to make the grinding plates face the saw blade, then rotating the adjusting bolts on both sides to drive the two grinding plates to contact the two sides of the saw blade respectively, and then starting the electric reciprocating saw to make the saw blade perform a reciprocating motion, the grinding plates on both sides grind and polish the saw blade. Without manual operation, polishing can be achieved by means of the movement of the saw blade itself, reducing the operation difficulty and operation risk.

[0017] 2. By providing an oiling sponge in the present invention, before grinding, auxiliary reagents such as cleaning liquid and rust remover are coated on the surface of the oiling sponge. Rotate the steering plate to make the oiling sponge face the saw blade, then rotate the adjusting bolt to make the two oiling sponges contact the two sides of the saw blade, and then start the electric reciprocating saw to make the oiling sponge perform pre-treatments such as cleaning and rust removal on the surface of the saw blade, thereby improving the smoothness of the movement of the saw blade during subsequent grinding and enhancing the polishing effect.

[0018] 3. By providing an oiling sponge in the present invention, after the grinding plate finishes polishing the surface of the saw blade, electric saw lubricating oil can be coated on the oiling sponge. Rotate the steering plate again to drive the oiling sponge to face the saw blade, and then press the oiling sponge against the surface of the saw blade. When the saw blade moves, the lubricating oil on the oiling sponge is evenly coated on the surface of the saw blade, improving the lubrication degree of the saw blade during subsequent use and playing a role in filling gaps and preventing rust, thereby extending the service life of the saw blade.

[0019] 4. By providing a positioning pin in the present invention, after rotating the steering plate to mutually convert the orientations of the grinding plate and the oiling sponge, the positioning pin on the top of the adjusting plate can be slid to insert the positioning pin into the positioning ring on the grinding frame or the sponge frame to position the steering plate, thereby ensuring that the grinding plate and the oiling sponge are always in a state of flat pressing against the surface of the saw blade and ensuring the effects of pre-treatment and grinding.

[0020] 5. By providing positioning pins in the present invention, the positioning pins are inserted into the positioning slots on the grinding plate and the oiling sponge respectively, enabling the grinding plate and the oiling sponge to be fixedly placed in the grinding frame and the sponge frame respectively. Meanwhile, it is convenient to replace the grinding plate and the oiling sponge, preventing the over-worn grinding plate from losing its grinding function, and the oiling sponge can be turned over so that the auxiliary reagent and the lubricating oil are respectively applied on different sides.

[0021] 6. By providing a support plate in the present invention, the assembly bolts and nuts will fasten the alignment bracket, fixing the four telescopic rods at the bottom of the electric saw housing, playing a supporting role for the electric reciprocating saw and this device. During the saw blade grinding process, the user does not need to touch or approach the electric saw, and can just turn off the electric saw when the saw blade grinding is completed, further improving the convenience and safety of this device.

[0022] 7. By providing fastening bolts in the present invention, when the support surface is not flat enough, the inclination of each telescopic rod can be adjusted. Then, each telescopic rod is stretched respectively, and the fastening bolt is rotated so that one end of the fastening bolt presses the telescopic end of the telescopic rod to fix the length of the telescopic rod, enabling the four support plates to respectively contact relatively flat areas, reducing the shaking of the electric saw and this device during the saw blade grinding process.

[0023] 8. By providing a balance rod and anti-slip pads in the present invention, the balance rod on one side of the support plate can increase the grounding area of the support plate, improving the stability of the support for the electric saw and this device. At the same time, if the plane of the support plate is relatively flat and smooth, the anti-slip pads at the bottom of the support plate and the balance rod can increase the friction between the support plate, the balance rod and the plane, preventing the whole device and the electric saw from sliding on the plane.

[0024] 9. By providing locking half-bolts and locking nuts in the present invention, after the two grinding plates are respectively pressed on both sides of the saw blade, the two locking half-bolts will be spliced into a complete bolt. At this time, the locking nuts are screwed onto the two locking half-bolts to lock the two steering plates and the grinding plates, avoiding the elastic deformation of the steering plates caused by the reciprocating movement of the saw blade, which may affect the grinding effect of the grinding plates on the saw blade.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0038] As Figures 1 to 8 shown, a multi-functional saw blade grinding and polishing device includes two housing fixing claws 1 that are rotatably installed with each other. As Figure 2 shown, a splicing plate 2 is fixedly installed at the bottom of each housing fixing claw 1. Two assembly holes are opened on the side walls of the two splicing plates 2. As Figure 3 shown, the two assembly holes at the same location are both inserted with the same assembly bolt 3. As Figure 1 shown, an assembly nut 4 is screwed at one end of each assembly bolt 3. In this embodiment, the assembly bolt 3 and the assembly nut 4 adopt a hand-tightening bolt group that is convenient for manual rotation. The bolts and nuts used in this multi-functional saw blade grinding and polishing device can both adopt common hand-tightening bolts on the market to improve the convenience of using the device. A same grinding component is provided on the two housing fixing claws 1;

[0039] The grinding component is used to grind and polish the saw blade as the saw blade of the electric reciprocating saw reciprocates. As Figure 1 shown, the grinding component includes two extension frames 5 respectively fixedly installed on the side walls of the two housing fixing claws 1. As Figure 4 shown, two adjusting plates 6 are arranged between the two extension frames 5. Fixing holes are opened on the side walls of the extension frames 5, and adjusting screw sleeves are fixedly installed inside the fixing holes. Adjusting bolts 7 are screwed inside the adjusting screw sleeves. One end of the adjusting bolts 7 on the same side penetrates through the adjusting screw sleeves and is rotatably installed on the side wall of the adjusting plate 6. A plurality of limiting slide rods 8 are fixedly installed on the side of the adjusting plate 6 close to the extension frame 5. A plurality of limiting slide holes are opened on the side walls of the extension frames 5, and the plurality of limiting slide rods 8 are respectively slidably installed inside the plurality of limiting slide holes. As Figure 6As shown, on one side of each of the two adjusting plates 6 close to each other, a horizontally arranged steering cylinder 9 is fixedly installed. Inside each of the steering cylinders 9, a steering rod 10 is rotatably installed. At one end of each of the steering rods 10, a steering plate 11 is fixedly installed. On one side of each of the steering plates 11, a grinding frame 12 is fixedly installed. Inside each of the grinding frames 12, a grinding plate 13 is arranged. In this embodiment, the thickness of the grinding plate 13 is greater than the depth of the grinding frame 12; specifically, when this multifunctional saw blade grinding and polishing device is in use, first, the two housing fixing claws 1 are buckled on the front housing of the electric reciprocating saw whose saw blade needs to be ground. Then, the two groups of assembly bolts 3 and assembly nuts 4 are screwed into the assembly holes on the splicing plate 2, so that the housing fixing claws 1 are fixedly assembled on the housing. By setting the grinding assembly, after the housing fixing claws 1 are assembled on the housing, at this time, the housing fixing claws 1 fix the two adjusting plates 6 and the two steering plates 11 on both sides of the saw blade through the extension frames 5 respectively. Rotate the two steering plates 11 to make the grinding plates 13 face the saw blade. Then, rotate the adjusting bolts 7 on both sides to make the two adjusting plates 6 approach each other under the limiting action of the limiting slide rods 8 until the two grinding plates 13 are respectively in contact with both sides of the saw blade. Then, start the electric reciprocating saw to make the saw blade perform a reciprocating motion. During the movement of the saw blade, the grinding plates 13 on both sides will perform relative grinding on the saw blade, thereby polishing the saw blade. And during the grinding process, no manual operation is required, and polishing can be achieved by relying on the movement of the saw blade itself, reducing the operation difficulty and operation risk.

[0040] As Figure 5As shown, a sponge frame 14 is fixedly installed on the side of the steering plate 11 facing away from the grinding frame 12. An oiling sponge 15 is arranged inside the sponge frame 14. In this embodiment, the thickness of the oiling sponge 15 is much greater than the depth of the sponge frame 14. Positioning pins 16 are slidably installed on the tops of the adjusting plates 6. Positioning rings 17 adapted to the positioning pins 16 are fixedly installed on the side walls of the grinding frame 12 and the sponge frame 14. The two positioning rings 17 on the same side are centrosymmetric about the axis center of the steering rod 10. Specifically, by providing the oiling sponge 15, auxiliary reagents such as cleaning liquid and rust remover are coated on the surface of the oiling sponge 15 before grinding. The steering plate 11 is rotated to make the oiling sponge 15 face the saw blade, and then the adjusting bolt 7 is rotated to make the two oiling sponges 15 contact both sides of the saw blade. Then the electric reciprocating saw is started, and the oiling sponge 15 pre-treats the surface of the saw blade, such as cleaning and rust removal, so as to improve the smoothness of the movement of the saw blade during subsequent grinding and improve the polishing effect. After the grinding plate 13 finishes polishing the surface of the saw blade, electric saw lubricating oil can be coated on the oiling sponge 15. The steering plate 11 is rotated again to drive the oiling sponge 15 to face the saw blade, and then the oiling sponge 15 is pressed against the surface of the saw blade. When the saw blade moves, the lubricating oil on the oiling sponge 15 is evenly coated on the surface of the saw blade, improving the lubrication degree of the saw blade during subsequent use and playing a role in filling gaps and preventing rust, thus prolonging the service life of the saw blade. By providing the positioning pins 16, after the orientation of the grinding plate 13 and the oiling sponge 15 is mutually converted by rotating the steering plate 11, the positioning pins 16 on the top of the adjusting plate 6 can be slid to make the positioning pins 16 insert into the positioning rings 17 on the grinding frame 12 or the sponge frame 14 to position the steering plate 11, so as to ensure that the grinding plate 13 and the oiling sponge 15 are always in a state of flat pressing against the surface of the saw blade, ensuring the effects of pre-treatment and grinding.

[0041] As Figure 5 shown, a relief chamfer 1501 is provided on the side of the oiling sponge 15. In this embodiment, the relief chamfer 1501 is provided on one of the horizontal sides of the oiling sponge 15, corresponding to the position of the saw teeth of the saw blade. Specifically, by providing the relief chamfer 1501, after the oiling sponge 15 is pressed against the surface of the saw blade, the relief chamfer 1501 can make the bottom side of the oiling sponge 15 avoid the saw teeth on the saw blade, thus preventing the problem of snagging when the saw teeth contact the oiling sponge 15 during the movement of the saw blade.

[0042] As Figure 7As shown, two positioning jacks are provided on the side walls of the grinding frame 12 and the sponge frame 14. Positioning pins 20 are slidably installed inside the positioning jacks. Two positioning slots adapted to the positioning pins 20 are provided on the side walls of the grinding plate 13 and the oiling sponge 15. Magnetic attraction blocks 21 are fixedly installed at one ends of the positioning pins 20 away from the positioning slots. Pulling plates 22 are fixedly installed on one sides of the two magnetic attraction blocks 21 on the same side. Specifically, by providing the positioning pins 20, the positioning pins 20 are inserted into the positioning slots on the grinding plate 13 and the oiling sponge 15. With the magnetic attraction effect of the magnetic attraction blocks 21, the grinding plate 13 and the oiling sponge 15 can be respectively fixedly placed in the grinding frame 12 and the sponge frame 14. At the same time, it is convenient to replace the grinding plate 13 and the oiling sponge 15, preventing the worn-out grinding plate 13 from losing its grinding function, and the oiling sponge 15 can be turned over so that the auxiliary reagent and the lubricating oil are respectively applied on different sides.

[0043] As Figure 2 shown, two hanging rings 23 are fixedly installed on the side wall of the splicing plate 2. The hanging rings 23 at the same position are aligned with the axis of the assembly hole. The assembly bolt 3 is inserted into the inside of the hanging ring 23. The adjusting brackets 24 are rotatably sleeved on the hanging rings 23. Telescopic support rods 25 are fixedly installed at the bottom ends of the adjusting brackets 24. As Figure 2 shown, support plates 27 are rotatably installed at the telescopic ends of the telescopic support rods 25. In this embodiment, the telescopic support rod 25 includes a fixed end and a telescopic end. The telescopic end is slidably installed inside the fixed end. The support plate 27 is rotatably installed at the bottom end of the telescopic end. Specifically, by providing the support plate 27, when the housing fixing claw 1 is locked by using the assembly bolt 3 and the assembly nut 4, the tightened assembly bolt 3 and assembly nut 4 will simultaneously fasten the adjusting bracket 24, so that the four telescopic support rods 25 are fixed at the bottom of the electric saw housing, and the four support plates 27 support on planes such as the ground and the tabletop, playing a supporting role for the electric reciprocating saw and this device. During the saw blade grinding process, the user does not need to contact or approach the electric saw, and can turn off the electric saw after waiting for the saw blade grinding to be completed, further improving the convenience and safety of this device.

[0044] As Figure 2As shown, fastening holes are formed in the side wall of the fixed end of the telescopic support rod 25. A fastening screw sleeve is fixedly installed inside the fastening hole. A fastening bolt 26 is screwed inside the fastening screw sleeve. One end of the fastening bolt 26 extends into the telescopic support rod 25 and contacts the side wall of the telescopic end of the telescopic support rod 25. Specifically, by providing the fastening bolt 26, when the support surface is not flat enough, the angles of the respective orientation adjustment brackets 24 can be adjusted, thereby adjusting the inclination of the telescopic support rod 25. Then, each telescopic support rod 25 is stretched respectively, and the fastening bolt 26 is rotated so that one end of the fastening bolt 26 presses against the telescopic end of the telescopic support rod 25 to fix the length of the telescopic support rod 25, enabling the four support plates 27 to respectively contact relatively flat areas and reducing the shaking of the electric saw and this device during the saw blade grinding process.

[0045] As Figure 1 shown, a plurality of balance rods 28 are fixedly installed on one side of each support plate 27. As Figure 8 shown, anti-slip pads 29 are fixedly installed at the bottoms of the support plates 27 and the balance rods 28. Specifically, by providing the balance rods 28 and the anti-slip pads 29, the balance rods 28 on one side of the support plate 27 can increase the grounding area of the support plate 27, improving the stability of the support for the electric saw and this device. At the same time, if the support plate plane is relatively flat and smooth, the anti-slip pads 29 at the bottoms of the support plates 27 and the balance rods 28 can increase the friction between the support plates 27, the balance rods 28 and the plane, preventing the overall sliding of this device and the electric saw on the plane.

[0046] As Figure 1 、 Figure 5 shown, locking half bolts 18 are fixedly installed on the tops of the steering plates 11. The bolt grooves on the two locking half bolts 18 are mutually adapted. A locking nut 19 is sleeved on one of the locking half bolts 18, and the locking nut 19 is adapted to the locking half bolt 18. In this embodiment, the distance between the two locking half bolts 18 is less than the distance between the two grinding plates 13. Specifically, by providing the locking half bolts 18 and the locking nut 19, after the two grinding plates 13 are respectively pressed against both sides of the saw blade, the two locking half bolts 18 located at the top will be spliced into a complete bolt. At this time, the locking nut 19 can be screwed on the two locking half bolts 18 to lock the locking half bolts 18 together, thereby locking the two steering plates 11 and the grinding plates 13 and preventing the elastic deformation of the steering plates 11 driven by the reciprocating movement of the saw blade from affecting the grinding effect of the grinding plates 13 on the saw blade.

[0047] In summary, when the multifunctional saw blade grinding and polishing device is in use, first fasten the two housing fixing claws 1 to the front housing of the electric reciprocating saw whose saw blade needs to be ground. Then screw the two groups of assembly bolts 3 and assembly nuts 4 into the assembly holes on the splicing plate 2 to fixedly assemble the housing fixing claws 1 on the housing. By setting the grinding assembly, after the housing fixing claws 1 are assembled on the housing, at this time, the housing fixing claws 1 fix the two adjusting plates 6 and the two steering plates 11 on both sides of the saw blade through the extension frame 5. Rotate the two steering plates 11 to make the grinding plates 13 face the saw blade. Then rotate the adjusting bolts 7 on both sides to make the two adjusting plates 6 approach each other under the limiting action of the limiting slide rods 8 until the two grinding plates 13 are respectively in contact with both sides of the saw blade. Then start the electric reciprocating saw to make the saw blade perform a reciprocating motion. During the movement of the saw blade, the grinding plates 13 on both sides will perform relative grinding on the saw blade, thereby polishing the saw blade. During the grinding process, no manual operation is required, and polishing can be achieved by relying on the movement of the saw blade itself, reducing the operation difficulty and operation risk. By setting the oiling sponge 15, before grinding, auxiliary reagents such as cleaning liquid and rust remover are coated on the surface of the oiling sponge 15. Rotate the steering plate 11 to make the oiling sponge 15 face the saw blade. Then rotate the adjusting bolts 7 to make the two oiling sponges 15 contact both sides of the saw blade. Then start the electric reciprocating saw to make the oiling sponge 15 perform pre-treatments such as cleaning and rust removal on the surface of the saw blade, thereby improving the smoothness of the saw blade movement during subsequent grinding and enhancing the polishing effect. After the grinding plates 13 finish polishing the surface of the saw blade, electric saw lubricating oil can be coated on the oiling sponge 15. Rotate the steering plate 11 again to drive the oiling sponge 15 to face the saw blade, and then press the oiling sponge 15 against the surface of the saw blade. When the saw blade moves, the lubricating oil on the oiling sponge 15 is evenly coated on the surface of the saw blade, improving the lubrication degree of the saw blade during subsequent use and playing a certain role in filling gaps and preventing rust, prolonging the service life of the saw blade. By setting the positioning pin 16, after rotating the steering plate 11 to mutually convert the orientations of the grinding plates 13 and the oiling sponges 15, the positioning pin 16 on the top of the sliding adjusting plate 6 can be inserted into the positioning ring 17 on the grinding frame 12 or the sponge frame 14 to position the steering plate 11, thereby ensuring that the grinding plates 13 and the oiling sponges 15 are always in a state of flat pressing against the surface of the saw blade, ensuring the effects of pre-treatment and grinding. By setting the relief chamfer 1501, after the oiling sponge 15 is pressed on the surface of the saw blade, the relief chamfer 1501 can make the bottom side of the oiling sponge 15 avoid the saw teeth on the saw blade, thereby preventing the problem of snagging when the saw teeth contact the oiling sponge 15 during the movement of the saw blade. By setting the positioning pins 20, the positioning pins 20 are inserted into the positioning slots on the grinding plates 13 and the oiling sponges 15 respectively. With the magnetic attraction of the magnetic blocks 21, the grinding plates 13 and the oiling sponges 15 can be fixedly placed in the grinding frame 12 and the sponge frame 14 respectively, and at the same time, it is convenient to replace the grinding plates 13 and the oiling sponges 15.Prevent the grinding plate 13 for preventing excessive wear from losing its grinding function, and the oiled sponge 15 can be turned over so that the auxiliary reagent and the lubricating oil are respectively applied on different sides. By setting the support plate 27, when the housing fixing claw 1 is locked by using the assembly bolt 3 and the assembly nut 4, the tightened assembly bolt 3 and assembly nut 4 will simultaneously fasten the alignment bracket 24, so that the four telescopic support rods 25 are fixed at the bottom of the electric saw housing, and the four support plates 27 support on planes such as the ground and the tabletop, playing a supporting role for the electric reciprocating saw and this device. During the saw blade grinding process, the user does not need to contact or approach the electric saw, and can just turn off the electric saw when the saw blade grinding is completed, further improving the convenience and safety of this device. By setting the fastening bolt 26, when the support surface is not flat enough, the angles of the respective alignment brackets 24 can be adjusted, and then the inclination of the telescopic support rods 25 can be adjusted. Then, each telescopic support rod 25 is stretched respectively, and the fastening bolt 26 is rotated so that one end of the fastening bolt 26 presses the telescopic end of the telescopic support rod 25 to fix the length of the telescopic support rod 25, enabling the four support plates 27 to respectively contact relatively flat areas, reducing the shaking of the electric saw and this device during the saw blade grinding process. By setting the balance rod 28 and the anti-slip pad 29, the balance rod 28 on one side of the support plate 27 can increase the grounding area of the support plate 27, improving the stability of the support for the electric saw and this device. At the same time, if the plane of the support plate is relatively flat and smooth, the anti-slip pads 29 at the bottom of the support plate 27 and the balance rod 28 can increase the friction between the support plate 27, the balance rod 28 and the plane, preventing the whole device and the electric saw from slipping on the plane. By setting the locking half bolts 18 and the locking nuts 19, after the two grinding plates 13 are respectively pressed on both sides of the saw blade, the two locking half bolts 18 at the top will be spliced together into a complete bolt. At this time, the locking nuts 19 can be screwed onto the two locking half bolts 18 to lock the locking half bolts 18 together, thereby locking the two steering plates 11 and the grinding plates 13, avoiding the elastic deformation of the steering plates 11 caused by the reciprocating movement of the saw blade and affecting the grinding effect of the grinding plates 13 on the saw blade.,
