Description

Technical Field

[0001] The invention relates to the technical field of electric saw accessories, and in particular 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 uses a motor to drive the saw blade to do reciprocating motion to perform sawing. It imitates the user moving the saw blade up and down when cutting, allowing the user to cut materials faster and with less effort. If the teeth of an electric saw blade are stored for a long time without protective measures, some rust and rust spots will appear on its surface, which will affect the activity of the saw blade. Therefore, the surface of the electric saw blade needs to be polished before use.

[0003] At present, electric saw blades are often polished manually using a simple polishing device, or the surface of the saw blade is rusted using a special electric saw blade grinder. However, no matter which polishing method is used, it is necessary to manually hold the polishing instrument for polishing. During the polishing process, not only the polishing angle and direction must be determined, but also the electric saw blade grinder must be held tightly to maintain a moderate angle and strength to avoid excessive wear. Protective gear must also be worn, and attention must be paid to avoiding saw teeth and debris at all times, which makes the actual operation difficult and cumbersome. Therefore, a multifunctional saw blade polishing device is proposed. Summary of the invention

At the same time, if the support plate surface is relatively flat and smooth, the anti-skid pad at the bottom of the support plate and the balance bar can increase the friction between the support plate, the balance bar and the surface, thereby preventing the device and the electric saw from sliding as a whole on the surface. 9. The present invention provides locking half-bolts and locking nuts so that 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.

[0019] like Figures 1 to 8 As shown, a multifunctional saw blade grinding and polishing device comprises two housing fixing claws 1 which are rotatably mounted relative to each other. Figure 2 As shown, the bottom of the housing fixing claw 1 is fixedly mounted with a split plate 2, and the side walls of the two split plates 2 are provided with two assembly holes, such as Figure 3 As shown, two assembly holes at the same location are both plugged with the same assembly bolt 3. Figure 1 As shown, one end of the assembly bolt 3 is threaded with an assembly nut 4. In this embodiment, the assembly bolt 3 and the assembly nut 4 adopt a hand-tightened bolt group that is convenient for manual rotation.

Figure 1 As shown, the grinding assembly includes two extension frames 5 respectively fixedly mounted on the side walls of the two housing fixing claws 1. Figure 4 As shown, two adjustment plates 6 are arranged between the two extension frames 5, and the side walls of the extension frames 5 are provided with fixing holes, and the insides of the fixing holes are fixedly installed with adjusting screw sleeves, and the insides of the adjusting screw sleeves are screwed with adjusting bolts 7, and one end of the adjusting bolt 7 located on the same side passes through the adjusting screw sleeve and is rotatably installed on the side wall of the adjustment plate 6, and a plurality of limiting slide bars 8 are fixedly installed on the side of the adjustment plate 6 close to the extension frame 5, and a plurality of limiting slide holes are opened on the side wall of the extension frame 5, and the plurality of limiting slide bars 8 are slidably installed in the interiors of the plurality of limiting slide holes, respectively, as shown in FIG. Figure 6 As shown, a horizontally arranged steering cylinder 9 is fixedly installed on one side of the two adjustment plates 6 close to each other, a steering rod 10 is rotatably installed inside the steering cylinder 9, a steering plate 11 is fixedly installed on one end of the steering rod 10, a grinding frame 12 is fixedly installed on one side of the steering plate 11, a grinding plate 13 is arranged inside the grinding frame 12, and in this embodiment, the thickness of the grinding plate 13 is greater than the depth of the grinding frame 12; specifically, when the multifunctional saw blade grinding and polishing device is in use, firstly, the two casing fixing claws 1 are buckled on the front end casing of the electric reciprocating saw whose saw blade needs to be polished, and then two sets of assembly bolts 3 and assembly nuts 4 are screwed into the assembly holes on the splicing plate 2, so that the casing fixing claws 1 are fixedly assembled on the casing, and the grinding assembly is set , so that after the casing fixing claw 1 is assembled on the casing, the casing fixing claw 1 fixes the two adjustment plates 6 and the two steering plates 11 on both sides of the saw blade through the extension frame 5, and rotates the two steering plates 11 to make the grinding plate 13 face the saw blade, and then rotates the adjusting bolts 7 on both sides to make the two adjustment plates 6 approach each other under the limiting action of the limiting slide bar 8, until the two grinding plates 13 are driven to contact the two sides of the saw blade respectively, and then start the electric reciprocating saw to make the saw blade reciprocate. During the movement of the saw blade, the grinding plates 13 on both sides will grind the saw blade relatively, and then polish the saw blade. During the grinding process, there is no need for manual operation, and polishing can be achieved with the help of the movement of the saw blade itself, which reduces the difficulty and risk of operation.

[0020] like Figure 5As shown, a sponge frame 14 is fixedly installed on the side of the steering plate 11 away from the grinding frame 12, and an oiled sponge 15 is arranged inside the sponge frame 14. In this embodiment, the thickness of the oiled sponge 15 is much greater than the depth of the sponge frame 14, and a positioning pin 16 is slidably installed on the top of the adjusting plate 6. A positioning plug ring 17 adapted to the positioning plug pin 16 is fixedly installed on the side walls of the grinding frame 12 and the sponge frame 14, and the two positioning plug rings 17 located on the same side are symmetrical along the axis center of the steering rod 10; specifically, by arranging the oiled sponge 15, before grinding, auxiliary agents such as cleaning liquid and rust remover are coated on the surface of the oiled sponge 15, the steering plate 11 is rotated to make the oiled sponge 15 face the saw blade, and then the adjusting bolt 7 is rotated to make the two oiled sponges 15 contact the two sides of the saw blade, and then the electric reciprocating saw is started, so that the oiled sponge 15 cleans and rusts the surface of the saw blade, so as to pre-treat the saw blade, thereby improving the movement of the saw blade during subsequent grinding. The smoothness of movement and the polishing effect are improved. After the polishing plate 13 finishes polishing the surface of the saw blade, the electric saw lubricating oil can be applied to the oiled sponge 15, and the steering plate 11 is rotated again to drive the oiled sponge 15 toward the saw blade, and then the oiled sponge 15 is pressed against the surface of the saw blade. When the saw blade moves, the lubricating oil on the oiled sponge 15 is evenly coated on the surface of the saw blade, thereby improving the lubrication of the saw blade during subsequent use, and playing a certain role in filling gaps and preventing rust, thereby extending the service life of the saw blade. By setting a positioning pin 16, after the rotating steering plate 11 converts the directions of the polishing plate 13 and the oiled sponge 15, the positioning pin 16 on the top of the adjustment plate 6 can be slid to insert the positioning pin 16 into the positioning insert ring 17 on the polishing frame 12 or the sponge frame 14, and the steering plate 11 is positioned, thereby ensuring that the polishing plate 13 and the oiled sponge 15 are always in a state of being pressed flat against the surface of the saw blade, thereby ensuring the effect of pretreatment and polishing.

[0021] like Figure 5 As shown, the side of the oil sponge 15 is provided with a clearance chamfer 1501. In the present embodiment, the clearance chamfer 1501 is provided on one of the horizontal sides of the oil sponge 15, corresponding to the position of the saw teeth of the saw blade. Specifically, by providing the clearance chamfer 1501, after the oil sponge 15 is pressed against the surface of the saw blade, the clearance chamfer 1501 can make the bottom side of the oil sponge 15 avoid the saw teeth on the saw blade, thereby preventing the saw teeth from contacting the oil sponge 15 during the movement of the saw blade and causing the problem of wire snagging.

[0022] like Figure 7As shown, two positioning holes are provided on the side walls of the polishing frame 12 and the sponge frame 14, and positioning pins 20 are slidably installed inside the positioning holes. Two positioning slots compatible with the positioning pins 20 are provided on the side walls of the polishing plate 13 and the oiling sponge 15, and a magnetic block 21 is fixedly installed on the end of the positioning pin 20 away from the positioning slot, and a pull plate 22 is fixedly installed on one side of the two magnetic blocks 21 on the same side; specifically, by arranging the positioning pins 20, the positioning pins 20 and the positioning slots on the polishing plate 13 and the oiling sponge 15 are mutually plugged, and with the magnetic effect of the magnetic block 21, the polishing plate 13 and the oiling sponge 15 can be fixedly placed in the polishing frame 12 and the sponge frame 14 respectively, and at the same time, it is convenient to replace the polishing plate 13 and the oiling sponge 15 to prevent the excessively worn polishing plate 13 from losing its polishing effect, and the oiling sponge 15 can be turned over so that the auxiliary agent and the lubricating oil are respectively applied on different sides.

[0023] like Figure 2 As shown, two hanging rings 23 are fixedly installed on the side wall of the spliced ​​plate 2, and the hanging rings 23 located at the same place are consistent with the axis of the assembly hole. The assembly bolts 3 are inserted into the inside of the hanging rings 23, and the hanging rings 23 are rotatably sleeved with adjustment brackets 24, and the bottom ends of the adjustment brackets 24 are fixedly installed with telescopic support rods 25, such as Figure 2 As shown, the telescopic ends of the telescopic support rods 25 are rotatably mounted with support plates 27. In the present embodiment, the telescopic support rods 25 include a fixed end and a telescopic end. The telescopic end is slidably mounted inside the fixed end, and the support plate 27 is rotatably mounted 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 bolts 3 and the assembly nuts 4, the tightened assembly bolts 3 and the assembly nuts 4 will simultaneously tighten the adjustment bracket 24, so that the four telescopic support rods 25 are fixed to the bottom of the electric saw housing, and the four support plates 27 are supported on the ground, the table and other flat surfaces, so as to support the electric reciprocating saw and the present device, so that during the saw blade grinding process, the user does not need to touch or approach the electric saw, and can wait for the saw blade grinding to be completed before turning off the electric saw, thereby further improving the convenience and safety of the present device.

[0024] like Figure 2As shown, a fastening hole is provided on the side wall of the fixed end of the telescopic support rod 25, and a fastening screw sleeve is fixedly installed inside the fastening hole, and a fastening bolt 26 is screwed inside the fastening screw sleeve, and one end of the fastening bolt 26 extends to the inside of the telescopic support rod 25 and contacts the side wall of the telescopic end of the telescopic support rod 25; specifically, by arranging the fastening bolt 26, when the supporting surface is not flat enough, the angle of each adjustment bracket 24 can be adjusted, thereby adjusting the inclination of the telescopic support rod 25, and then each telescopic support rod 25 is stretched respectively, and then the fastening bolt 26 is rotated so that one end of the fastening bolt 26 squeezes the telescopic end of the telescopic support rod 25, and the length of the telescopic support rod 25 is fixed, so that the four support plates 27 can contact relatively flat areas respectively, thereby reducing the shaking of the electric saw and the device during the saw blade grinding process.

[0025] like Figure 1 As shown, a plurality of balancing rods 28 are fixedly mounted on one side of the support plate 27. Figure 8 As shown, the bottom of the support plate 27 and the balance bar 28 are fixedly installed with anti-skid pads 29; specifically, by providing the balance bar 28 and the anti-skid pads 29, the balance bar 28 on one side of the support plate 27 can increase the ground contact area of ​​the support plate 27, thereby improving the stability of the support for the electric saw and the device. At the same time, if the support plate plane is relatively flat and smooth, the anti-skid pads 29 at the bottom of the support plate 27 and the balance bar 28 can increase the friction between the support plate 27, the balance bar 28 and the plane, thereby preventing the device and the electric saw from slipping as a whole on the plane.

[0026] like Figure 1 , Figure 5 As shown, a locking half-bolt 18 is fixedly installed on the top of the steering plate 11, and the bolt grooves on the two locking half-bolts 18 are adapted to each other. 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 the present embodiment, the spacing between the two locking half-bolts 18 is smaller than the spacing between the two grinding plates 13; specifically, by arranging the locking half-bolts 18 and the locking nut 19, after the two grinding plates 13 are respectively pressed on the two sides of the saw blade, the two locking half-bolts 18 at the top will be spliced ​​into a complete bolt. At this time, the locking nuts 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 plate 13 to prevent the steering plate 11 from causing elastic deformation during the reciprocating motion of the saw blade, thereby affecting the grinding effect of the grinding plate 13 on the saw blade.

[0027] In summary: when the multifunctional saw blade grinding and polishing device is in use, firstly, the two casing fixing claws 1 are buckled onto the front end casing of the electric reciprocating saw whose saw blade needs to be polished, and then the two sets of assembly bolts 3 and assembly nuts 4 are screwed into the assembly holes on the joint plate 2, so that the casing fixing claws 1 are fixedly assembled on the casing, and by setting the polishing assembly, after the casing fixing claws 1 are assembled on the casing, the casing fixing claws 1 fix the two adjustment plates 6 and the two steering plates 11 on both sides of the saw blade through the extension frame 5, and the two steering plates 11 are rotated to make the grinding plate 13 face the saw blade, and then the adjusting bolts 7 on both sides are rotated to make the two adjustment plates 6 approach each other under the limiting action of the limiting slide bar 8, until the two grinding plates 13 are driven to contact the two sides of the saw blade respectively, and then the electric saw is started. The reciprocating saw is driven to make the saw blade reciprocate. 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, polishing can be achieved by the movement of the saw blade itself without manual operation, thereby reducing the difficulty and risk of operation. By arranging the oiling sponge 15, before grinding, auxiliary agents such as cleaning liquid and rust remover are coated on the surface of the oiling sponge 15, 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 the two sides of the saw blade, and then the electric reciprocating saw is started, so that the oiling sponge 15 performs pre-treatment 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 improving the polishing effect. As a result, after the polishing plate 13 finishes polishing the surface of the saw blade, the electric saw lubricating oil can be applied to the oiling sponge 15, and the steering plate 11 is rotated again to drive the oiling sponge 15 toward 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, thereby improving the lubrication of the saw blade during subsequent use, and playing a certain role in filling gaps and preventing rust, thereby extending the service life of the saw blade. By setting a positioning pin 16, after the rotating steering plate 11 converts the directions of the polishing plate 13 and the oiling sponge 15, the positioning pin 16 on the top of the adjustment plate 6 can be slid to insert the positioning pin 16 into the positioning insert ring 17 on the polishing frame 12 or the sponge frame 14 to position the steering plate 11. Thereby, it is ensured that the grinding plate 13 and the oil sponge 15 are always in a state of being pressed flat against the surface of the saw blade, and the effect of pretreatment and grinding is ensured. By setting the yield chamfer 1501, after the oil sponge 15 is pressed against the surface of the saw blade, the yield chamfer 1501 can make the bottom side of the oil sponge 15 avoid the saw teeth on the saw blade, thereby preventing the saw teeth from contacting the oil sponge 15 and causing the problem of wire snagging during the movement of the saw blade. By setting the positioning pin 20, the positioning pin 20 and the positioning slots on the grinding plate 13 and the oil sponge 15 are mutually plugged, and the magnetic attraction of the magnetic block 21 can be used to fix the grinding plate 13 and the oil sponge 15 in the grinding frame 12 and the sponge frame 14 respectively, and it is convenient to replace the grinding plate 13 and the oil sponge 15.The grinding plate 13 is prevented from losing its grinding function due to excessive wear, and the oiling sponge 15 can be turned over so that the auxiliary agent and the lubricating oil are applied to different sides respectively. By setting the supporting plate 27, when the housing fixing claw 1 is locked by the assembly bolt 3 and the assembly nut 4, the tightened assembly bolt 3 and the assembly nut 4 will simultaneously tighten the adjustment bracket 24, so that the four telescopic support rods 25 are fixed to the bottom of the electric saw housing, and the four supporting plates 27 are supported on the ground, the table and other planes, which plays a role in the electric reciprocating saw and the device. The function of the support is that during the saw blade sharpening process, the user does not need to touch or approach the electric saw, and the electric saw can be turned off when the saw blade is sharpened, which further improves the convenience and safety of the device. By setting the fastening bolt 26, when the support surface is not flat enough, the angle of each adjustment bracket 24 can be adjusted, and then the inclination of the telescopic support rod 25 can be adjusted, and then each telescopic support rod 25 can be stretched respectively, and then the fastening bolt 26 is rotated to make one end of the fastening bolt 26 squeeze the telescopic end of the telescopic support rod 25, so as to fix the length of the telescopic support rod 25. The four support plates 27 can be fixed so that they can contact a relatively flat area respectively, thereby reducing the shaking of the electric saw and the device during the saw blade grinding process. By setting the balance bar 28 and the anti-skid pad 29, the balance bar 28 on one side of the support plate 27 can increase the ground contact area of ​​the support plate 27, thereby improving the stability of the support for the electric saw and the device. At the same time, if the support plate surface is relatively flat and smooth, the anti-skid pad 29 at the bottom of the support plate 27 and the balance bar 28 can increase the friction between the support plate 27, the balance bar 28 and the plane, thereby preventing the device and the electric saw from being on the plane. The locking half bolts 18 and the locking nuts 19 are arranged so that after the two grinding plates 13 are pressed on both sides of the saw blade respectively, the two locking half bolts 18 at the top will be spliced ​​together to form a complete bolt. At this time, the locking nuts 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 plate 13, so as to avoid the steering plate 11 from causing elastic deformation during the reciprocating motion of the saw blade, thereby affecting the grinding effect of the grinding plate 13 on the saw blade.
