Description

Technical Field

[0001] The invention relates to the technical field of diamond saw blade processing and grinding, and in particular to a high-precision grinding process for a diamond saw blade. Background Art

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

[0003] When processing diamond saw blades in the factory, after welding between the cutter head and the base body, the cutter head needs to be polished. On the one hand, it is to expose the diamond, and on the other hand, it is also for the aesthetics of the product, which is conducive to better sales of the product.

[0004] When grinding the cutter head, the circumferential edge of the blade is generally ground, and both sides of the blade are sandblasted, but the grooves, slits and splayed grooves of the blade cannot be ground, which affects the overall appearance of the blade and is not conducive to product sales. At the same time, since the slits and slits are not ground, their surfaces are relatively rough, which is not conducive to smoother discharge of water during cutting.

[0005] However, it takes a lot of time to grind the grooves, slits and splayed grooves, and it is inconvenient for workers to operate tools to grind these grooves, which results in the lack of suitable grinding processes for these positions. Therefore, it is necessary to design a high-precision grinding process for diamond saw blades that can process grooves, slits and splayed grooves, and does not require workers to grind them, and the time spent in the grinding process can be reduced. Summary of the invention

[0006] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a high-precision grinding process for diamond saw blades, which can process grooves, gap grooves and splayed grooves, and does not require workers to grind, and the time spent in the grinding process can be reduced.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment: The present invention provides a high-precision grinding process for a diamond saw blade, such as Figure 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.

[0029] Step 1: Install the saw blade 10 on the saw blade rotating mechanism 6; 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; 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 to approach the saw blade 10 at the same time, the annular cutter 13 cuts and grinds the slit groove 10b, the grinding wheel 2 12 grinds the splayed groove 10c, and the grinding wheel 1 11 grinds the blade groove 10a. After the grinding is completed, the lifting mechanism 1 and the grinding wheel 2 12 are reset; 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 step 3 is repeated again. The preset angle is the mid-section angle between the two cutter heads; Step 5: When the blade grooves 10a, gap grooves 10b and splayed grooves 10c at all positions are polished, the saw blade 10 drives the saw blade rotating mechanism 6 to rotate at high speed, and the inner push mechanism 2, which was originally in the reset position, continues to move backward a preset distance, so that the grinding stone 14 slides horizontally and fits the outer edge of the saw blade 10. The preset distance of the backward movement is the distance that allows the grinding stone 14 to contact the saw blade 10.

[0030] Through the above-mentioned grinding process, the saw blade 10 can be installed once to complete grinding in multiple places. At the same time, multiple grinding positions do not interfere with each other. At the same time, the equipment can be used for processing and grinding for saw blades 10 of different sizes. And when the saw blade 10 rotates at high speed, the grinding wheel 12 and the annular cutter 13 can be further away from the saw blade 10, which can avoid the collision of the high-speed rotating saw blade 10 with the annular cutter 13 and the grinding wheel 12 due to misoperation. If this structure is not set, the equipment cannot be set to a high-speed rotation mode, which means that high-speed grinding and groove grinding need to be divided into two devices, and installation and disassembly consume more time. Because once the equipment fails, the high-speed rotating saw blade 10 collides with the grinding wheel 12 or the annular cutter 13, which will cause one of the collision objects to break, which is too dangerous. The equipment in the factory needs to be established under the condition that the workers can use it safely.

[0031] In order to prevent the grinding wheel 11, the grinding wheel 2, and the annular cutter 13 from colliding with the saw blade 10 during the insertion process, the grinding wheel 11, the grinding wheel 2, and the annular cutter 13 need to be clamped with the saw blade 10 one by one, but the three are individually controlled and driven by the lifting mechanism 1 and the inner pushing mechanism 2, which leads to a long insertion process and a large number of cutter heads to be processed. In this way, the cutter heads cannot be processed quickly. In order to achieve fast processing, for this reason, Figure 4As shown, the inner push mechanism 2 includes a push rod 2a and two linear drivers that are symmetrically distributed. The push rod 2a is connected to the two linear drivers in a transmission manner. Each linear driver is connected to a transmission column 2b, a linear adjustment mechanism 2c and a guide column 2d. The push rod 2a is fixedly installed on the vertical lifting seat of the jacking mechanism 1. The two sides of the push rod 2a are respectively provided with strip-shaped slide grooves 2a1. The transmission column 2b is inserted into the strip-shaped slide grooves 2a1. The transmission column 2b is fixedly installed on the linear adjustment mechanism 2c. The guide column 2d can be slidably installed on the rotating seat installed on the angle adjustment mechanism 5. The linear adjustment mechanism 2c is fixedly installed at the bottom of the guide column 2d, and the rotating mechanism 3 is fixedly installed at the top of the guide column 2d. When the jacking mechanism 1 moves, the transmission column 2b can be driven to move, so that the guide column 2d slides linearly along the rotating seat of the rotating mechanism 3, that is, the rotating mechanism 3 is pushed close to or away from the grinding wheel 11. In this way, the grinding wheel 11, the grinding wheel 12 and the annular cutter 13 are guaranteed to move synchronously. The grinding wheel 11, the grinding wheel 12 and the annular cutter 13 have different diameters. The wheel body with the largest diameter will contact the saw blade 10 first. If no collision occurs during the process, the other wheel bodies will continue to contact the saw blade 10, thereby ensuring rapid processing of the cutter head.

[0032] When the angle adjustment mechanism 5 changes its angle, the guide column 1 2d is driven to move linearly through the rotating seat, so that the corresponding grinding wheel 2 12 or the annular cutter 13 changes its position synchronously to achieve angle adjustment.

[0033] During the process of angle change, the guide column 2d and the transmission column 2b will slide, but this will result in the grinding wheel 11, the grinding wheel 12 and the annular cutter 13 being unable to contact the saw blade 10 at the same time. By adjusting the linear adjustment mechanism 2c, the positions of the transmission column 2b and the guide column 2d can be changed to compensate for the displacement change during angle adjustment. At the same time, if the shapes of the splayed groove 10c and the slit groove 10b change, the grinding wheel 12 and the annular cutter 13 can be replaced so that they can fit the splayed groove 10c and the slit groove 10b for processing.

[0034] In order to adjust the position of the transmission column 2b so that the grinding wheel 11, the grinding wheel 2 and the annular cutter 13 can all contact with the saw blade 10 at the same time, Figure 5As shown, the linear adjustment mechanism 2c includes a slider 2c1, a screw rod 2c2 and a slideway 2c3, the slideway 2c3 is fixedly connected to the bottom of the guide column 2d, the slider 2c1 can be slidably installed on the slideway 2c3, the screw rod 2c2 can be rotatably installed in the slideway 2c3, a threaded hole is provided in the middle of the slider 2c1, the screw rod 2c2 is engaged with the threaded hole, and a handle is provided on one side of the slideway 2c3. When the transmission column 2b needs to be adjusted in position, the slider 2c1 can be slid along the slideway 2c3 by rotating the screw rod 2c2, so that the position of the transmission column 2b can be adjusted, that is, the grinding wheel 11, the grinding wheel 2 12 and the annular cutter 13 can finally contact the saw blade 10 at the same time.

[0035] In order to be able to adjust the angle of the grinding wheel 12 and the annular cutter 13 through the angle adjustment mechanism 5, for this purpose, as shown in FIG. Figure 4 and Figure 5 As shown, each angle adjustment mechanism 5 includes an arc-shaped slider 5a, an arc-shaped slide rail 5b, a screw rod 5c, a hinged rod 5d and two adjusting nuts 5e. The arc-shaped slide rail 5b is fixedly mounted on the frame of the jacking mechanism 1, and the arc-shaped slider 5a can be slidably mounted on the arc-shaped slide rail 5b. A guide hole for the arc-shaped slider 5a to slide is provided in the middle of the guide column 2d. One end of the hinged rod 5d is hinged to the arc-shaped slider 5a, and the other end of the hinged rod 5d is hinged to the screw rod 5c. A locking hole for the screw rod 5c to pass through is provided on the angle adjustment mechanism 5. The two adjusting nuts 5e are respectively located on both sides of the locking hole and are clamped on the arc-shaped slide rail 5b, and the two adjusting nuts 5e are both meshed and connected with the screw rod 5c. The central axis of the arc-shaped slider 5a is coaxially arranged with the rotation axis of the saw blade rotating mechanism 6. When the angle needs to be adjusted, the screw rod 5c is pulled linearly along the arc-shaped slide rail 5b, so that the screw rod 5c pulls the hinge rod 5d to move, and the arc-shaped slide block 5a slides linearly along the arc-shaped slide rail 5b, that is, the angle of the grinding wheel 12 and the annular cutter 13 is changed. Even if the angle is adjusted, since the central axis of the arc-shaped slide block 5a is coaxial with the rotation axis of the saw blade rotating mechanism 6, the middle section of the grinding wheel 12 and the annular cutter 13 keeps intersecting with the rotation axis of the saw blade rotating mechanism 6.

[0036] In order to make the grinding stone 14 and the annular cutter 13 move in opposite directions to ensure the safety of the workers, Figure 6As shown, the reverse driving mechanism 4 includes a rotating rod 4a, a mounting frame 4b, a slide column 1 4c and a slide column 2 4d, the mounting frame 4b is fixedly mounted on the arc-shaped slide rail 5b, the rotating rod 4a is rotatably connected to the mounting frame 4b, the slide column 2 4d is fixedly connected to the grinding stone 14, the slide column 1 4c is fixedly connected to the rotating mechanism 3, two slide grooves 4a1 are provided at both ends of the rotating rod 4a, and the slide column 1 4c and the slide column 2 4d are respectively inserted into the two slide grooves 4a1. When the rotating mechanism 3 moves upward, the rotating mechanism 3 will drive the rotating rod 4a to rotate, and the rotating rod 4a will drive the slide column 2 4d to move, so that the slide column 2 4d drives the grinding stone 14 to the right away from the saw blade 10, and vice versa, when the grinding stone 14 approaches the saw blade 10, the annular cutter 13 is away from the saw blade 10, that is, the movement of the grinding stone 14 and the annular cutter 13 is reversed, ensuring the safety of the workers.

[0037] In order to realize that the grinding stone 14 can slide linearly, and at the same time, after the size of the saw blade 10 changes, the grinding stone 14 can also contact the saw blade 10 when the lifting mechanism 1 moves backward to a preset position, for this purpose, Figure 6 As shown, a clamping seat 7 is provided at the bottom of the grinding stone 14, and a guide post 2 8 is fixedly provided on the right side of the clamping seat 7. The guide post 2 8 is slidably connected with the mounting frame 4b, and a guide hole for the guide post 2 8 to slide is provided on the mounting frame 4b. An external thread is provided on the outer edge of the tail of the guide post 2 8, and the tail of the guide post 2 8 is inserted into the clamping plate 15. The sliding post 2 4d is fixedly connected with the clamping plate 15. The sliding post 2 4d is fixedly connected with the clamping plate 15. Adjusting nuts 2 9 are provided on both sides of the clamping plate 15, and the adjusting nuts 2 9 are meshed with the external threads on the guide post 2 8. When the rotating rod 4a rotates to change its position, the rotating rod 4a will push the sliding post 2 4d, so that the sliding post 2 4d pushes the clamping plate 15, and the guide post 2 8 can slide linearly along the mounting frame 4b, that is, the grinding stone 14 can slide close to the saw blade 10. The grinding stone 14 can be pulled out upward along the clamping seat 7. Since the saw blade 10 rotates 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 the grinding stone 14 can move backward to a preset position after the size of the saw blade 10 changes, so that the grinding stone 14 can still contact the saw blade 10.

[0038] like Figure 7As shown, the lifting mechanism 1 includes a guide seat 1a, a guide column 1b, an electric push rod 1c and a lifting plate 1d. The guide column 1b can be installed on the guide seat 1a in a vertically sliding manner, the electric push rod 1c is fixedly installed on the guide seat 1a, the lifting plate 1d is fixedly installed on the top of the guide column 1b, and the output end of the electric push rod 1c is fixedly connected to the lifting plate 1d, the rotating mechanism 3 located in the middle is fixedly connected to the top of the lifting plate 1d, and the push rod 2a is fixedly connected to the lifting plate 1d. When the electric push rod 1c is pushed upward, the electric push rod 1c will push the lifting plate 1d to move vertically, so that the rotating mechanism 3 can move vertically, so that the grinding wheel 11 can 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 at the same time. There are three situations in which the electric push rod 1c pushes, namely, the grinding position, the reset position, and the preset position generated by the inner push mechanism 2 originally in the reset position continuing to move backwards for a preset distance. These three positions may need to be adjusted more, because an electric push rod is used, and only the distance needs to be changed by programming.

[0039] like Figure 7 As shown, the rotating mechanism 3 includes a rotating motor 3a, a pulley set 3b, a mounting shaft 3c and a locking nut 3d. The rotating motor 3a is connected to the mounting shaft 3c through the pulley set 3b. The grinding wheel 11 is clamped on the mounting shaft 3c. The locking nut 3d is meshed and installed on the end of the mounting shaft 3c. The locking nut 3d is in conflict with the grinding wheel 11. When the rotating motor 3a works, the rotating motor 3a can drive the mounting shaft 3c to rotate through the pulley set 3b, so that the grinding wheel 11 rotates to grind the eight-shaped groove 10c. If it needs to be replaced, the locking nut 3d is unscrewed, and the grinding wheel 11 is removed and replaced.

[0040] When processing, the above-mentioned working process of step 1 to step 5 is sufficient. When the size of the saw blade 10 is changed, the angle is first adjusted through the angle adjustment mechanism 5 so that the grinding wheel 12 and the annular cutter 13 can face the eight-shaped groove 10c and the gap groove 10b. Then, it is lifted upward to the grinding position through the lifting mechanism 1, and then the linear adjustment mechanism 2c is adjusted so that the grinding wheel 12 and the annular cutter 13 can fit the eight-shaped groove 10c and the gap groove 10b respectively. Then, it is moved downward to the preset position through the lifting mechanism 1, and then the adjustment nut 2 9 is adjusted so that the grinding stone 14 fits the saw blade 10, that is, the whole adjustment process is completed.
