Description

Technical Field

[0001] The present invention relates to the technical field of diamond saw blade processing and polishing, and particularly relates to a high-precision polishing process for diamond saw blades. Background Art

[0002] Diamond saw blades are mainly used for cutting reinforced concrete roads, walls, etc., which can not only reduce cutting wear but also ensure the heat dissipation effect.

[0003] When processing diamond saw blades in a factory, after the welding between the cutting head and the substrate is completed, the cutting head needs to be polished. On the one hand, it makes the diamond exposed, and on the other hand, it is also for the aesthetics of the product, which is beneficial to the better sales of the product.

[0004] When polishing the cutting head, generally, the circumferential edge of the blade is polished, and sandblasting is used for both sides of the blade. However, the grooves, slot grooves, and bevel grooves of the blade cannot be polished. This results in poor overall aesthetics of the blade, which is not conducive to the sales of the product. At the same time, since the slot grooves and bevel grooves are not polished, their surfaces are relatively rough, which is not conducive to the smooth discharge of water during cutting.

[0005] However, polishing the grooves, slot grooves, and bevel grooves takes a lot of time, and it is not convenient for workers to operate tools to polish these grooves. This leads to the lack of a suitable polishing process for these positions. Therefore, it is necessary to design a high-precision polishing process for diamond saw blades that can process the grooves, slot grooves, and bevel grooves, without the need for manual polishing by workers, and can reduce the time spent during the polishing process. Summary of the Invention

[0006] Aiming at the above-mentioned technical deficiencies, the purpose of the present invention is to provide a high-precision polishing process for diamond saw blades that can process the grooves, slot grooves, and bevel grooves, without the need for manual polishing by workers, and can reduce the time spent during the polishing process.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the present invention provides a high-precision grinding process for a diamond saw blade, including a lifting mechanism, a reverse driving mechanism, a saw blade rotating mechanism, a grinding wheel 1, a grinding wheel 2, an annular cutter, a grinding stone, two inner pushing mechanisms, three rotating mechanisms and two angle adjustment mechanisms, the saw blade is detachably mounted on the saw blade rotating mechanism, the three rotating mechanisms are all mounted on the outer edge bottom of the saw blade, the grinding wheel 1 is fixedly mounted on the rotating shaft of the middle rotating mechanism, the grinding wheel 2 and the annular cutter are mounted on the rotating shafts of the other two rotating mechanisms, the lifting end of the lifting mechanism is fixedly connected to the middle rotating mechanism, and the lifting mechanism is used to move upward The grinding wheel 1 is lifted up to approach the saw blade, and the rotating seats on the two angle adjustment mechanisms are fixedly connected to the other two rotating mechanisms. The two angle adjustment mechanisms are used to change the angle between the grinding wheel 2 and the annular cutter and the cross section of the saw blade. The two angle adjustment mechanisms are respectively fixedly installed on the two inner pushing mechanisms. The two inner pushing mechanisms are used to push the grinding wheel 2 and the annular cutter toward the saw blade respectively. The grinding stone can slide horizontally to approach or move away from the saw blade. One end of the reverse drive mechanism is transmission connected to one of the inner pushing mechanisms, and the other end of the reverse drive mechanism is transmission connected to the grinding stone. When the working end of the inner pushing mechanism moves toward the saw blade, the reverse drive mechanism pushes the grinding stone away from the saw blade.

[0009] Step 2: Adjust the angles of the two angle adjustment mechanisms, so that the grinding wheel 2 faces the eight-shaped grooves of the two cutter heads, the annular cutter faces the gap grooves of the other two cutter heads, and the grinding wheel 1 faces the blade groove of one cutter head;

[0010] Step 3: The three rotating mechanisms work simultaneously, the lifting mechanism and the inner pushing mechanism push the three rotating mechanisms to approach the saw blade at the same time, the annular cutter cuts and grinds the slit groove, the grinding wheel 2 grinds the splayed groove, and the grinding wheel 1 grinds the blade groove. After the grinding is completed, the lifting mechanism and the grinding wheel 2 are reset;

[0011] Step 4: After one grinding is completed, the saw blade drives the saw blade rotating mechanism to rotate by a preset angle, and step 3 is repeated again. The preset angle is the mid-section angle between the two cutter heads;

[0012] Step 5: When all blade grooves, slit grooves and figure-eight grooves are polished, the saw blade drives the saw blade rotating mechanism to rotate at high speed. The inner push mechanism, which was originally in the reset position, continues to move backward a preset distance, so that the grinding stone slides horizontally and fits the outer edge of the saw blade. The preset distance of backward movement is the distance that allows the grinding stone to contact the saw blade.

Each linear driver drives a transmission column, a linear adjustment mechanism, and a first guide post respectively.

The first screw rod meshes with the threaded hole. A handle is arranged on one side of the slideway.

[0015] Preferably, each angle adjustment mechanism includes an arc-shaped slider, an arc-shaped slide rail, a second screw rod, a hinge rod, and two first adjusting nuts. The arc-shaped slide rail is fixedly installed on the frame of the jacking mechanism. The arc-shaped slider is slidably installed on the arc-shaped slide rail. A guide hole for the arc-shaped slider to slide is formed in the middle of the first guide post. One end of the hinge rod is hinged to the arc-shaped slider, and the other end of the hinge rod is hinged to the second screw rod. A locking hole for the second screw rod to pass through is formed in the angle adjustment mechanism. The two first adjusting nuts are respectively located on both sides of the locking hole and clamped on the arc-shaped slide rail, and both first adjusting nuts are meshed and connected with the second screw rod. The central axis of the arc-shaped slider is coaxially arranged with the rotation axis of the saw blade rotating mechanism.

[0016] Preferably, the reverse driving mechanism includes a rotating rod, an installation frame, a first sliding column, and a second sliding column. The installation frame is fixedly installed on the arc-shaped slide rail. The rotating rod is rotatably connected to the installation frame. The second sliding column is fixedly connected to the grinding stone. The first sliding column is fixedly connected to the rotating mechanism. Two chutes are formed at both ends of the rotating rod. The first sliding column and the second sliding column are respectively inserted into the two chutes.

[0017] Preferably, a clamping seat is arranged at the bottom of the grinding stone. A second guide post is fixedly arranged on the right side of the clamping seat. The second guide post is slidably connected to the installation frame. A guide hole for the second guide post to slide is formed on the installation frame. External threads are formed on the outer edge of the tail of the second guide post, and the tail of the second guide post is inserted into the clamping plate. The second sliding column is fixedly connected to the clamping plate. Adjusting nuts two are arranged on both sides of the clamping plate, and the adjusting nuts two are meshed with the external threads on the second guide post.

[0018] Preferably, the jacking mechanism includes a guide seat, a third guide post, an electric push rod, and a jacking plate. The third guide post is vertically slidably installed on the guide seat. The electric push rod is fixedly installed on the guide seat. The jacking plate is fixedly installed on the top of the third guide post, and the output end of the electric push rod is fixedly connected to the jacking plate. The rotating mechanism in the middle is fixedly connected to the top of the jacking plate, and the push rod is fixedly connected to the jacking plate.

[0019] Preferably, the rotating mechanism includes a rotating motor, a pulley group, a mounting shaft, and a locking nut. The rotating motor is drivingly connected to the mounting shaft through the pulley group. The first grinding wheel is clamped on the mounting shaft, and the locking nut is meshingly installed at the end of the mounting shaft and abuts against the first grinding wheel.

[0020] The beneficial effects of the present invention are as follows: The high-precision grinding process of the diamond saw blade can complete the grinding of the outer edge, groove, slot, and bevel groove of the saw blade with only one installation, saving the time of workers. At the same time, the grinding process does not require workers to operate. And the grinding positions at multiple places do not interfere with each other. At the same time, for saw blades of different sizes, this equipment can be used for processing and grinding. And when the saw blade rotates at high speed, the second grinding wheel and the annular cutter can be further away from the saw blade, which can avoid the collision between the high-speed rotating saw blade and the annular cutter and the second grinding wheel due to misoperation.

[0021] When moving through the jacking mechanism, the transmission column can be driven to move, so that the first guide post slides linearly along the rotating seat of the rotating mechanism, that is, the rotating mechanism is pushed closer to or away from the first grinding wheel. In this way, it is ensured that the first grinding wheel, the second grinding wheel, and the annular cutter move synchronously. Among them, the diameters of the first grinding wheel, the second grinding wheel, and the annular cutter are different, and the wheel body with the largest diameter will contact the saw blade first. If no collision occurs during this process, the other wheel bodies will continue to contact the saw blade, that is, the rapid processing of the cutter head is ensured.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment: The present invention provides a high-precision grinding process for diamond saw blades, as Figures 1-3As shown, it includes a lifting mechanism 1, a reverse driving mechanism 4, a saw blade rotating mechanism 6, a grinding wheel 11, a grinding wheel 2 12, an annular cutter 13, a grinding stone 14, two inner pushing mechanisms 2, three rotating mechanisms 3 and two angle adjustment mechanisms 5. The saw blade 10 is detachably mounted on the saw blade rotating mechanism 6, and the three rotating mechanisms 3 are all mounted on the outer edge bottom of the saw blade 10. The grinding wheel 11 is fixedly mounted on the rotating shaft of the middle rotating mechanism 3, and the grinding wheel 2 12 and the annular cutter 13 are mounted on the rotating shafts of the other two rotating mechanisms 3. By working through the three rotating mechanisms 3, the grinding wheel 11, the grinding wheel 2 12 and the annular cutter 13 can be driven to rotate. The lifting end of the lifting mechanism 1 is fixedly connected to the middle rotating mechanism 3. The lifting mechanism 1 is used to lift the grinding wheel 11 upward to approach the saw blade 10. The rotating seats on the two angle adjustment mechanisms 5 are fixedly connected to the other two rotating mechanisms 3. The two angle adjustment mechanisms 5 are used to change the angle between the grinding wheel 12 and the annular cutter 13 and the cross-section of the saw blade 10. When the diameter of the saw blade 10 becomes larger, the size of the diamond blade thereon will not change, but the positions of its multiple adjacent diamonds will change, which causes the grinding wheel 12 and the annular cutter 13 to be unable to continue to grind the slit groove 10b and the eight-shaped groove 10c. At this time, it is necessary to adjust the angle of the angle adjustment mechanism 5 so that the grinding wheel 12 and the annular cutter 13 can grind the eight-shaped groove 10c and the annular cutter 13 can grind the slit groove 10b when they are pushed linearly, and the grinding wheel 11 is pushed upward by the lifting mechanism 1 so that the blade groove 10a can be ground. The two angle adjustment mechanisms 5 are respectively fixedly installed on the two inner pushing mechanisms 2. The two inner pushing mechanisms 2 are used to push the grinding wheel 12 and the annular cutter 13 toward the saw blade 10 respectively. The grinding stone 14 can slide horizontally close to or away from the saw blade 10. One end of the reverse drive mechanism 4 is transmission connected to one of the inner pushing mechanisms 2, and the other end of the reverse drive mechanism 4 is transmission connected to the grinding stone 14. When the working end of the inner pushing mechanism 2 moves toward the saw blade 10, the reverse drive mechanism 4 pushes the grinding stone 14 away from the saw blade 10.

[0033] Step 1: Install the saw blade 10 on the saw blade rotating mechanism 6;

[0034] Step 2: Adjust the angles of the two angle adjustment mechanisms 5, the grinding wheel 2 12 faces the eight-shaped grooves 10c of the two cutter heads, the annular cutter 13 faces the gap grooves 10b of the other two cutter heads, and the grinding wheel 11 faces the blade groove 10a of one cutter head;

[0035] Step 3: The three rotating mechanisms 3 work simultaneously. The lifting mechanism 1 and the inner pushing mechanism 2 push the three rotating mechanisms 3 towards the saw blade 10 simultaneously. The annular cutter 13 cuts and grinds the slot 10b, the second grinding wheel 12 grinds and processes the eight-shaped groove 10c, and the first grinding wheel 11 grinds and processes the blade groove 10a. After the grinding is completed, the lifting mechanism 1 and the second grinding wheel 12 return to their original positions;

[0036] Step 4: After one grinding is completed, the saw blade 10 drives the saw blade rotating mechanism 6 to rotate by a preset angle, and then repeat Step 3. The preset angle is the included angle of the midsection between two cutting heads;

[0037] Step 5: When the blade grooves 10a, slots 10b, and eight-shaped grooves 10c at all positions are all ground, the saw blade 10 drives the saw blade rotating mechanism 6 to rotate at a high speed. The inner pushing mechanism 2 that was originally in the reset position continues to move backward by a preset distance, so that the abrasive stone 14 slides horizontally to fit the outer edge of the saw blade 10. The preset backward movement distance is the distance that can make the abrasive stone 14 contact the saw blade 10.

[0038] Through the above grinding process, the saw blade 10 can be installed once to complete grinding at multiple locations. At the same time, the multiple grinding positions do not interfere with each other. At the same time, for saw blades 10 of different sizes, this equipment can be used for processing and grinding. And when the saw blade 10 rotates at a high speed, the second grinding wheel 12 and the annular cutter 13 can be further away from the saw blade 10, which can avoid collisions between the high-speed rotating saw blade 10 and the annular cutter 13 and the second grinding wheel 12 due to misoperation. If this structure is not set, the equipment cannot be set to a high-speed rotation mode, which will result in the need for two separate devices for high-speed grinding and groove grinding, and the installation and disassembly consume a lot of time. Because once the equipment fails, the high-speed rotating saw blade 10 collides with the second grinding wheel 12 or the annular cutter 13, which will cause one of the colliding objects to break, which is too dangerous. The equipment in the factory needs to be used under the condition that workers can ensure safety.

[0039] In order to avoid collisions between the first grinding wheel 11, the second grinding wheel 12, and the annular cutter 13 and the saw blade 10 during the insertion process, it is necessary to engage the first grinding wheel 11, the second grinding wheel 12, and the annular cutter 13 with the saw blade 10 one by one. However, the three are individually controlled and driven by the lifting mechanism 1 and the inner pushing mechanism 2, which results in a relatively long insertion process. And there are many cutting heads to be processed. Using this method, the cutting heads cannot be processed quickly. In order to achieve fast processing, therefore, as Figure 4As shown in the figure, the internal pushing mechanism 2 includes a push rod 2a and two linear drivers symmetrically distributed. The push rod 2a is in transmission connection with the two linear drivers. Each linear driver drives a transmission column 2b, a linear adjustment mechanism 2c, and a first guide post 2d respectively. The push rod 2a is fixedly installed on the vertical lifting seat of the lifting mechanism 1. Strip-shaped sliding grooves 2a1 are respectively formed on both sides of the push rod 2a. The transmission column 2b is inserted into the strip-shaped sliding groove 2a1. The transmission column 2b is fixedly installed on the linear adjustment mechanism 2c. The first guide post 2d is slidably installed on the rotating seat of the angle adjustment mechanism 5. The linear adjustment mechanism 2c is fixedly installed at the bottom of the first guide post 2d. The rotating mechanism 3 is fixedly installed at the top of the first guide post 2d. When the lifting mechanism 1 moves, it can drive the transmission column 2b to move, so that the first guide post 2d linearly slides along the rotating seat of the rotating mechanism 3, that is, to push the rotating mechanism 3 closer to or farther away from the first grinding wheel 11. In this way, it is ensured that the first grinding wheel 11, the second grinding wheel 12, and the annular cutting tool 13 move synchronously. Among them, the diameters of the first grinding wheel 11, the second grinding wheel 12, and the annular cutting tool 13 are different. The wheel body with the largest diameter will contact the saw blade 10 first. If no collision occurs during this process, the other wheel bodies will continue to contact the saw blade 10, that is, the rapid processing of the tool head is ensured.

[0040] Among them, when the angle adjustment mechanism 5 changes the angle, it will drive the first guide post 2d to linearly move through the rotating seat, so that the corresponding second grinding wheel 12 or the annular cutting tool 13 synchronously changes its position to achieve angle adjustment.

[0041] During the process of angle change, the first guide post 2d and the transmission column 2b will slide. However, this results in that the first grinding wheel 11, the second grinding wheel 12, and the annular cutting tool 13 cannot contact the saw blade 10 simultaneously. By adjusting the linear adjustment mechanism 2c, the positions of the transmission column 2b and the first guide post 2d can be changed to compensate for the displacement change during angle adjustment. At the same time, if the shapes of the eight-shaped groove 10c and the gap groove 10b change, the second grinding wheel 12 and the annular cutting tool 13 can be replaced so that they can fit and process with the eight-shaped groove 10c and the gap groove 10b.

[0042] In order to be able to adjust the position of the transmission column 2b so that the first grinding wheel 11, the second grinding wheel 12, and the annular cutting tool 13 can finally contact the saw blade 10 simultaneously. For this reason, as Figure 5As shown, the linear adjustment mechanism 2c includes a slider 2c1, a first screw 2c2, and a slideway 2c3. The slideway 2c3 is fixedly connected to the bottom of the first guide post 2d. The slider 2c1 is slidably mounted on the slideway 2c3. The first screw 2c2 is rotatably mounted within the slideway 2c3. A threaded hole is formed in the middle of the slider 2c1, and the first screw 2c2 meshes with the threaded hole. A handle is provided on one side of the slideway 2c3. When the position of the transmission post 2b needs to be adjusted, by rotating the first screw 2c2, the slider 2c1 slides along the slideway 2c3, so that the position of the transmission post 2b can be adjusted, that is, the grinding wheels 11, 12 and the annular cutting tool 13 can finally contact the saw blade 10 simultaneously.

[0043] In order to be able to adjust the angles of the second grinding wheel 12 and the annular cutting tool 13 through the angle adjustment mechanism 5, for this purpose, as Figure 4 and Figure 5 shown, each angle adjustment mechanism 5 includes an arc-shaped slider 5a, an arc-shaped slide rail 5b, a second screw 5c, a hinge rod 5d, and two first adjusting nuts 5e. The arc-shaped slide rail 5b is fixedly mounted on the frame of the lifting mechanism 1. The arc-shaped slider 5a is slidably mounted on the arc-shaped slide rail 5b. A guide hole for the arc-shaped slider 5a to slide through is formed in the middle of the first guide post 2d. One end of the hinge rod 5d is hinged to the arc-shaped slider 5a, and the other end of the hinge rod 5d is hinged to the second screw 5c. A locking hole for the second screw 5c to pass through is formed in the angle adjustment mechanism 5. The two first adjusting nuts 5e are respectively located on both sides of the locking hole and clamp the arc-shaped slide rail 5b, and both first adjusting nuts 5e are meshed and connected with the second screw 5c. The central axis of the arc-shaped slider 5a is coaxial with the rotation axis of the saw blade rotation mechanism 6. When angle adjustment is required, by linearly pulling the second screw 5c along the arc-shaped slide rail 5b, the second screw 5c will pull the hinge rod 5d to move, so that the arc-shaped slider 5a can linearly slide along the arc-shaped slide rail 5b, that is, the angles of the second grinding wheel 12 and the annular cutting tool 13 are changed. Among them, even if the angle is adjusted, since the central axis of the arc-shaped slider 5a is coaxial with the rotation axis of the saw blade rotation mechanism 6, the middle section of the second grinding wheel 12 and the annular cutting tool 13 intersects with the rotation axis of the saw blade rotation mechanism 6.

[0044] In order to enable the abrasive stone 14 and the annular cutting tool 13 to move in the reverse direction and ensure the safety of workers, for this purpose, as Figure 6As shown, the reverse drive mechanism 4 includes a rotating rod 4a, a mounting bracket 4b, a first sliding column 4c, and a second sliding column 4d. The mounting bracket 4b is fixedly mounted on the arc-shaped slide rail 5b. The rotating rod 4a is rotatably connected to the mounting bracket 4b. The second sliding column 4d is fixedly connected to the grinding stone 14, and the first sliding column 4c is fixedly connected to the rotating mechanism 3. Two sliding grooves 4a1 are formed at both ends of the rotating rod 4a. The first sliding column 4c and the second sliding column 4d are respectively inserted into the two sliding grooves 4a1. When the rotating mechanism 3 moves upward, the rotating mechanism 3 will drive the rotating rod 4a to rotate. The rotating rod 4a will drive the second sliding column 4d to move, so that the second sliding column 4d drives the grinding stone 14 to move away from the saw blade 10 to the right. Conversely, when the grinding stone 14 approaches the saw blade 10, the annular cutting tool 13 moves away from the saw blade 10, that is, the movements of the grinding stone 14 and the annular cutting tool 13 are in reverse, ensuring the safety of the workers.

[0045] In order to enable the grinding stone 14 to slide linearly, and at the same time, after the size of the saw blade 10 changes, when the lifting mechanism 1 moves backward to a preset position, the grinding stone 14 can still contact the saw blade 10. For this reason, as Figure 6 shown, a clamping seat 7 is provided at the bottom of the grinding stone 14. A second guide post 8 is fixedly provided on the right side of the clamping seat 7. The second guide post 8 is slidably connected to the mounting bracket 4b. A guide hole for the second guide post 8 to slide is formed on the mounting bracket 4b. External threads are formed on the outer edge of the tail of the second guide post 8, and the tail of the second guide post 8 is inserted into the clamping plate 15. The second sliding column 4d is fixedly connected to the clamping plate 15. Adjusting nuts 9 are provided on both sides of the clamping plate 15. The adjusting nuts 9 are meshed with the external threads on the second guide post 8. After the rotating rod 4a rotates and changes its position, the rotating rod 4a will push the second sliding column 4d, so that the second sliding column 4d pushes the clamping plate 15, and the second guide post 8 can slide linearly along the mounting bracket 4b, that is, the grinding stone 14 can slide closer to the saw blade 10. The grinding stone 14 can be pulled out upward along the clamping seat 7. Since the rotation direction of the saw blade 10 is downward, the grinding stone 14 will not be lifted upward during the processing. By rotating the adjusting nut 9, the distance between the grinding stone 14 and the clamping plate 15 is adjusted, so that after the size of the saw blade 10 changes, when moving backward to a preset position, the grinding stone 14 can still contact the saw blade 10.

[0046] As Figure 7As shown in the figure, the jacking mechanism 1 includes a guide seat 1a, a third guide post 1b, an electric push rod 1c, and a jacking plate 1d. The third guide post 1b is vertically slidably mounted on the guide seat 1a. The electric push rod 1c is fixedly mounted on the guide seat 1a. The jacking plate 1d is fixedly mounted on the top of the third guide post 1b, and the output end of the electric push rod 1c is fixedly connected to the jacking plate 1d. The rotating mechanism 3 in the middle is fixedly connected to the top of the jacking plate 1d, and the push rod 2a is fixedly connected to the jacking plate 1d. When the electric push rod 1c pushes upward, the electric push rod 1c will push the jacking plate 1d to move vertically, so that the rotating mechanism 3 can move vertically, enabling the first grinding wheel 11 to grind the blade groove 10a. At the same time, when the rotating mechanism 3 moves vertically upward, it will drive the push rod 2a to move simultaneously. The position where the electric push rod 1c makes a push is divided into three cases, that is, the grinding position, the reset position, and the inner pushing mechanism 2 that was originally in the reset position and continues to move backward a preset distance to generate a preset position. These three positions can be adjusted more according to needs. Since an electric push rod is used, only the distance needs to be changed by programming.

[0047] As Figure 7 shown, the rotating mechanism 3 includes a rotating motor 3a, a pulley group 3b, a mounting shaft 3c, and a locking nut 3d. The rotating motor 3a is drivingly connected to the mounting shaft 3c through the pulley group 3b. The first grinding wheel 11 is clamped on the mounting shaft 3c, and the locking nut 3d is meshed and installed at the end of the mounting shaft 3c, and the locking nut 3d abuts against the first grinding wheel 11. By operating the rotating motor 3a, the rotating motor 3a can drive the mounting shaft 3c to rotate through the action of the pulley group 3b, enabling the first grinding wheel 11 to rotate and grind the eight-shaped groove 10c. When replacement is needed, the locking nut 3d is unscrewed and the first grinding wheel 11 is removed and replaced.

[0048] During processing, the working process of the above-mentioned steps one to five can be carried out. When the size of the saw blade 10 is changed, first, the angle is adjusted through the angle adjustment mechanism 5 so that the second grinding wheel 12 and the annular cutter 13 can be directly opposite the eight-shaped groove 10c and the gap groove 10b. Then, the jacking mechanism 1 is jacked upward to the grinding position, and then the linear adjustment mechanism 2c is adjusted so that the second grinding wheel 12 and the annular cutter 13 can be respectively attached to the eight-shaped groove 10c and the gap groove 10b. Subsequently, the jacking mechanism 1 moves downward to the preset position, and then the adjusting nut two 9 is adjusted so that the grinding stone 14 is attached to the saw blade 10, thus completing the entire adjustment process. However, it should also be noted that when in the reset position, the grinding stone 14 does not contact the saw blade 10, and at the same time, the positions of the first grinding wheel 11, the second grinding wheel 12, and the annular cutter 13 will not collide with the rotating saw blade 10.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
