Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel dressing, in particular to a grinding wheel side thickness dressing device and a processing method thereof. Background Art

[0002] In recent years, with the development of the automotive, electronics, and refrigeration industries, the demand for high-precision superhard grinding wheels has been increasing year by year. Since these industries have very strict requirements on the dimensional accuracy and surface quality of the processed parts, it is necessary to control the dressing amount of the grinding wheel end face and the side abrasive layer to ensure the service life of the grinding wheel.

[0003] Patent No. CN208697167U discloses a grinding wheel dressing tool for an end grinder, the grinding wheel dressing tool comprising a seat, a grinding stone, a grinding stone fastener, a top screw and a clamping piece. The seat is a rectangular parallelepiped, and a grinding stone slot is provided on one end face. A deep screw hole is provided on the side of the seat close to the grinding stone slot. The grinding stone fastener and the grinding stone are both accommodated in the grinding stone slot. The top screw passes through the deep screw hole, and one end is screwed to the grinding stone fastener to fix the grinding stone in the grinding stone slot. The clamping piece is connected to the bottom of the seat to fix the grinding wheel dressing tool on an external base. The grinding wheel dressing tool has a simple structure and is easy to operate. It not only solves the problem of grinding wheel fillet appearing during manual grinding wheel dressing, but also improves the operational safety of the entire operation process.

[0004] In the prior art, the grinding stone is fixed on the base to avoid manual dressing operation by holding the grinding stone. However, in the dressing process, the dressing amount of the grinding wheel needs to be strictly controlled. It is possible that during the dressing process, grinding stones of different mesh sizes need to be replaced in the middle of the grinding process to control the dressing amount. However, in the replacement process, it is necessary to disassemble the grinding stone and assemble a new grinding stone. The disassembly and assembly process is relatively complicated, which reduces the efficiency of grinding wheel dressing. At the same time, when the grinding stone and the grinding wheel are in contact at high speed, high temperature will be generated on the surface of the grinding stone. Direct disassembly may cause damage to the skin of the staff. Waiting for cooling before taking it out will further reduce work efficiency. It is not suitable for large-scale grinding wheel dressing.

[0022] A method for trimming the thickness of a grinding wheel side surface comprises the following steps:

[0023] S1, first put the grinding stones of different mesh sizes into the feeding plate in turn, clamp them with the clamping block in the feeding plate, and then drive the dressing plate and the feeding plate to rotate through the main shaft. During the rotation, the fixed box on the dressing plate and the notch on the feeding plate slowly overlap in parallel. At the same time, when the feeding plate rotates, it will drive the bidirectional screw in the pushing box to rotate, so that the grinding stone is pushed into the fixed box by the pushing head when the notch overlaps with the fixed box;

[0024] S2, after the grinding stone is pushed into the fixing box, it drives the dressing disk to rotate again. During the rotation, the fixing box is driven to the bottom of the mounting disk. While rotating, the lower gear is driven to rotate by the lower rack, so that the grinding stone is fixed by the rubber pad. When the grinding stone reaches the bottom of the mounting disk, the grinding wheel in the mounting disk is driven to rotate, and then the grinding wheel is brought into contact with the grinding stone for dressing work;

[0025] S3, when the fixed box rotates toward the mounting plate, another set of fixed boxes will overlap with another set of grinding stones on the feeding plate, and the other set of grinding stones will be pushed onto the fixed box again through the pushing mechanism. The other set of grinding stones can be grinding stones of different mesh sizes or different types, which is convenient for dressing work according to the dressing process of the grinding wheel.

[0026] Beneficial effects of the present invention:

[0027] (1) When the feed disc rotates, the present invention uses the teeth at the bottom of the feed disc to drive the push gear on the push box to rotate. When the push gear rotates, it will drive the bidirectional screw inside the push box to rotate. When the bidirectional screw rotates, it will drive the threaded disc to move toward the grinding stone. While moving, it drives the telescopic column and the push head to approach the grinding stone and abut against the grinding stone. When the feed disc rotates slowly, the push head is used to slowly push the grinding stone into the fixed box. At the same time, a telescopic spring is arranged in the telescopic column. Since the push head may abut against the inner wall of the feed disc when the feed disc rotates, in order to avoid hard contact between the push head and the feed disc, the telescopic spring will be squeezed when the push head contacts the feed disc. When the notch on the feed disc is parallel to the fixed box, the push head will pass through the notch and contact the grinding stone again, thereby pushing the grinding stone into the fixed box.

[0028] (2) In the present invention, after the grinding stone is pushed onto the bottom plate in the fixed box, the dressing disk is driven to rotate again. During the rotation, the dressing disk will drive the fixed box to reach the lower rack, and make the lower gear at the bottom of the fixed box mesh with the lower rack. At the same time, the fixed box on the dressing disk is rotated to the bottom of the mounting disk. During the movement of the fixed box, the lower gear is driven to rotate by the lower rack, and then the transmission shaft is used to drive the rotating shaft and the crown gear inside the fixed box to rotate, and then the crown gear is used to drive the driven gear to rotate, thereby driving the fixed screw to rotate. When the fixed screw rotates, it will drive the two sets of moving plates to move toward the grinding stone, and then the grinding stone is fixed by the rubber pad.

[0029] (3) After a group of grinding stones have finished their work, the present invention rotates the dressing disk to rotate the grinding stones that have finished their work to the end away from the feed disk. During this rotation, the upper gear at the bottom of the fixed box will contact the upper rack on the sliding base, and the upper rack is arranged on the periphery of the upper gear. After contacting the upper rack, the upper gear will be driven by the upper rack to rotate in the opposite direction when it rotates again, thereby driving the crown gear to rotate again, so that the two groups of rubber pads release the fixation of the grinding stone, and finally the grinding stone can be removed.

[0030] (4) The present invention provides a telescopic spring in the telescopic column. Since the push head may abut against the inner wall of the feed tray when the feed tray rotates, in order to avoid hard contact between the push head and the feed tray, the telescopic spring will be squeezed when the push head contacts the feed tray. When the notch on the feed tray is parallel to the fixed box, the push head will pass through the groove and contact the grindstone again, thereby pushing the grindstone into the fixed box.

DETAILED DESCRIPTION

[0042] 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.

[0043] See also Figure 1-Figure 9 As shown, the present application provides a grinding wheel side thickness dressing device, including a workbench 1 and a sliding base 2, and also includes:

[0044] A mounting plate 7, arranged on the workbench 1, for mounting a grinding wheel;

[0045] A dressing disc 3 is rotatably arranged on the sliding base 2 and is used for dressing the grinding wheel;

[0046] A fixing mechanism 4, arranged on the dressing disc 3, for fixing the grinding stone;

[0047] The feeding mechanism 5 is rotatably arranged on the sliding base 2 and is used for feeding grinding stones of different mesh sizes;

[0048] A pushing mechanism 6 is arranged in the feeding mechanism 5 and is used to assist the feeding mechanism 5;

[0049] The workbench 1 is rotatably connected with a moving shaft 11; two groups of the moving shaft 11 are provided; a moving block 12 is threadedly connected to the moving shaft 11; the sliding base 2 is fixedly connected to the moving block 12; a hand crank 13 is rotatably connected to the side wall of the workbench 1; the moving shaft 11 is driven to rotate by the hand crank 13; a connecting column 22 is fixedly connected to the sliding base 2;

[0050] During operation, in the prior art, the grinding stone is fixed on the base body to avoid manual hand-held grinding stone for dressing operation. However, in the dressing process, the dressing amount of the grinding wheel needs to be strictly controlled. It is possible that during the dressing process, it is necessary to replace grinding stones of different mesh sizes in the middle of the process to control the dressing amount. However, in the replacement process, it is necessary to disassemble it and assemble a new grinding stone at the same time. The disassembly and assembly process is relatively cumbersome, resulting in reduced efficiency of grinding wheel dressing. At the same time, when the grinding stone and the grinding wheel are in contact at high speed, high temperature will be generated on the surface of the grinding stone. Direct disassembly may cause damage to the skin of the staff. Waiting for cooling before taking it out will further reduce work efficiency. It is not suitable for large-scale grinding wheel dressing. In order to prevent such incidents from happening, first, the grinding stone should be replaced according to the grinding stone. In the process of wheel dressing, grinding stones of different mesh sizes and different types are installed in the feeding mechanism 5 in sequence, and then the dressing disk 3 and the receiving mechanism are rotated. While rotating, the grinding stone is pushed into the fixing mechanism 4 in the dressing disk 3 according to the pushing mechanism 6. After the grinding stone reaches the inside of the fixing mechanism 4, the dressing disk 3 is driven to rotate again. During the rotation, the grinding stone is fixed by the fixing mechanism 4. After the fixation is completed, it contacts the grinding wheel in the mounting disk 7 for dressing work. During the dressing process, the staff can rotate the hand crank 13 on the side wall of the workbench 1. During the rotation, the hand crank 13 drives the moving shaft 11 inside the workbench 1 to rotate, and at the same time uses the moving block 12 to drive the sliding base 2 to move, thereby driving the grinding stone to move back and forth on the grinding wheel to realize the dressing of the grinding wheel.

[0051] like Figure 3As shown, the feeding mechanism 5 includes a feeding tray 51; the sliding base 2 is rotatably connected with a main shaft 31 and a secondary shaft 53; the end of the main shaft 31 away from the sliding base 2 is fixedly connected to the trimming disk 3; the end of the secondary shaft 53 away from the sliding base 2 is fixedly connected to the feeding tray 51; a connecting belt 33 is sleeved on the main shaft 31 and the secondary shaft 53; the fixing mechanism 4 includes a fixing box 41; the fixing box 41 is fixedly connected to the trimming disk 3; the fixing box 41 is provided with four groups; the side wall of the feeding tray 51 is provided with a notch 57; the notch 57 is provided with four groups; the side wall of the notch 57 is provided with a notch 54; the pushing mechanism 6 includes a pushing box 61; the end of the connecting column 22 away from the sliding base 2 is connected to the pushing The box 61 is fixed; the pushing box 61 is arranged in the middle of the feeding tray 51; a bidirectional screw rod 62 is rotatably connected in the pushing box 61; a threaded disk 63 is threadedly connected to the bidirectional screw rod 62; a connecting rod 64 is fixed to the side wall of the threaded disk 63; a telescopic column 65 is fixed to the end of the connecting rod 64 away from the threaded disk 63; a telescopic spring 67 is fixed in the telescopic column 65; a push head 68 is fixed to the end of the telescopic spring 67 away from the telescopic column 65; the push head 68 is slidably arranged in the telescopic column 65; a pushing gear 621 is fixed to the end of the bidirectional screw rod 62 away from the pushing box 61; teeth 52 are fixed to the middle of the feeding tray 51; the pushing gear 621 is meshed and connected with the teeth 52;

[0052] During operation, after the grinding stone is installed on the feeding plate 51, the main shaft 31 on the rotating sliding base 2 is rotated, and then the connecting belt 33 is used to drive the secondary shaft 53 to rotate, that is, the dressing plate 3 and the feeding plate 51 are driven to rotate at the same time, and the feeding plate 51 and the dressing plate 3 rotate in opposite directions, the dressing plate 3 rotates counterclockwise, and the feeding plate 51 rotates clockwise. When the dressing plate 3 rotates counterclockwise, it will drive one group of fixed boxes 41 close to the feeding plate 51. When the feeding plate 51 rotates counterclockwise, it will drive the grinding stone in the notch 57 close to the fixed box 41. When the fixed box 41 and the grinding stone are parallel and overlapped, the grinding stone is pushed into the fixed box 41 by the pushing head 68 in the pushing box 61. The pushing method is: when the feeding plate 51 rotates, the teeth 52 at the bottom of the feeding plate 51 will be used to drive the pushing gear 621 on the pushing box 61 to rotate. When the push gear 621 rotates, it will drive the bidirectional screw rod 62 inside the push box 61 to rotate. When the bidirectional screw rod 62 rotates, it will drive the threaded disk 63 to move toward the grindstone, and at the same time drive the telescopic column 65 and the push head 68 to approach the grindstone and abut against the grindstone. Under the slow rotation of the feed tray 51, the push head 68 is used to slowly push the grindstone into the fixed box 41. At the same time, a telescopic spring 67 is provided in the telescopic column 65. Since the push head 68 may abut against the inner wall of the feed tray 51 when the feed tray 51 rotates, in order to avoid hard contact between the push head 68 and the feed tray 51, the telescopic spring 67 will be squeezed when the push head 68 contacts the feed tray 51. When the notch 57 on the feed tray 51 is parallel to the fixed box 41, the push head 68 will pass through the slot 54 and contact the grindstone again, thereby pushing the grindstone into the fixed box 41.

[0053] like Figure 6 As shown, a rotating shaft 42 is rotatably connected in the fixed box 41; a crown gear 43 is fixedly connected to the rotating shaft 42; a connecting plate 44 is fixedly connected to the side wall of the fixed box 41; a fixed screw rod 45 is rotatably connected to the side wall of the connecting plate 44; one end of the fixed screw rod 45 away from the connecting plate 44 is rotatably connected to the side wall of the fixed box 41; a driven gear 46 is fixedly connected to the fixed screw rod 45; the driven gear 46 is meshed and connected with the crown gear 43; a screw rod 46 is threadedly connected to the fixed screw rod 45 The movable plate 47; the side wall of the movable plate 47 is fixedly connected with a rubber pad 48; the bottom of the fixed box 41 is rotatably connected with a transmission shaft 49; the transmission shaft 49 is fixedly connected with an upper gear 492 and a lower gear 491; the side wall of the main shaft 31 is fixedly connected with a lower rack 32; the lower rack 32 is movably engaged with the lower gear 491; the side wall of the fixed box 41 is fixedly connected with a bottom plate 411; the movable plate 47 is arranged to penetrate the bottom plate 411; the output end of the transmission shaft 49 is fixedly connected with the input end of the rotating shaft 42;

[0054] During operation, after the grinding stone is pushed onto the bottom plate 411 in the fixed box 41, the dressing disc 3 is driven to rotate again. During rotation, the dressing disc 3 will drive the fixed box 41 to reach the lower rack 32, and make the lower gear 491 at the bottom of the fixed box 41 mesh with the lower rack 32. At the same time, the fixed box 41 on the dressing disc 3 is rotated to the bottom of the mounting disc 7. During the movement of the fixed box 41, the lower gear 491 is driven to rotate by the lower rack 32, and then the transmission shaft 49 is used to drive the rotating shaft 42 and the crown gear 43 inside the fixed box 41 to rotate, and then the crown gear 43 is used to drive the driven gear 46 to rotate, thereby driving the fixed screw rod 45 to rotate. When the fixed screw rod 45 rotates, it will drive the two sets of moving plates 47 moves toward the grindstone, and then the grindstone is fixed by the rubber pad 48, wherein the rubber pad 48 is a flexible material. In order to adapt to different types of grindstones, the rubber pad 48 will be squeezed by the grindstone when it contacts the grindstone. When encountering a larger grindstone, the rubber pad 48 is squeezed deeper, and when encountering a smaller grindstone, the rubber pad 48 is squeezed shallower, and the grindstone and the rubber pad 48 will not be damaged during the squeezing process, and the rubber pad 48 can be restored to its original state after the squeezing is completed. At the same time that the dressing disk 3 drives the grindstone to rotate to the bottom of the mounting disk 7, another group of grindstones on the feeding disk 51 are also pushed by the push head 68 to another group of fixed boxes 41, so that different grindstones can be used according to the dressing process of the grinding wheel.

[0055] like Fig. 9 As shown, a clamping spring 55 is fixedly connected to the side wall of the notch 57; a clamping block 56 is fixedly connected to one end of the clamping spring 55 away from the feeding tray 51;

[0056] During operation, the staff sequentially places grinding stones of different models and mesh sizes into the notch 57 , and clamps the grinding stones through the clamping block 56 to prevent the grinding stones from tipping over when the feed tray 51 rotates.

[0057] like Figure 6 As shown, an upper rack 21 is fixedly connected to the sliding base 2; the upper gear 492 is movably meshed with the upper rack 21;

[0058] During operation, after a group of grindstones has finished working, the dressing disk 3 is rotated to rotate the grindstone that has finished working to the end away from the feed disk 51. During this rotation, the upper gear 492 at the bottom of the fixed box 41 will contact the upper rack 21 on the sliding base 2, and the upper rack 21 is arranged on the periphery of the upper gear 492. After contacting with the upper rack 21, when it rotates again, the upper rack 21 will drive the upper gear 492 to rotate in the opposite direction, thereby driving the crown gear 43 to rotate again, so that the two groups of rubber pads 48 release the fixation of the grindstone, and finally the grindstone can be removed.

[0059] like Figure 1 As shown, the trimming plate 3 is arranged in parallel with the feeding plate 51; the spindle 31 is driven by a motor;

[0060] During operation, the main shaft 31 is driven to rotate by a motor which is not shown in the figure, and the trimming plate 3 is at the same height as the feeding plate 51 .

[0061] like Figure 1 As shown, the mounting plate 7 is arranged above the trimming plate 3;

[0062] During operation, the grinding wheel is installed in the mounting plate 7, and finally the grinding wheel in the mounting plate 7 is driven to rotate, and then the grinding stone is rotated under the grinding wheel, so as to perform the dressing work of the grinding wheel.

[0063] See also Figure 1-Figure 9 As shown, the present application provides a method for trimming the thickness of a grinding wheel side, comprising the following steps:

[0064] S1, first put the grinding stones of different mesh sizes into the feeding tray 51 in turn, clamp them through the clamping block 56 in the feeding tray 51, and then drive the trimming tray 3 and the feeding tray 51 to rotate through the main shaft 31, and when rotating, the fixed box 41 on the trimming tray 3 and the notch 57 on the feeding tray 51 slowly overlap in parallel, and at the same time, when the feeding tray 51 rotates, it will drive the bidirectional screw 62 in the pushing box 61 to rotate, so that the grinding stone is pushed into the fixed box 41 by the pushing head 68 when the notch 57 overlaps with the fixed box 41;

[0065] S2, after the grinding stone is pushed into the fixing box 41, the dressing disc 3 is driven to rotate again. During the rotation, the fixing box 41 is driven to the bottom of the mounting disc 7. While rotating, the lower gear 491 is driven to rotate by the lower rack 32, so that the grinding stone is fixed by the rubber pad 48. When the grinding stone reaches the bottom of the mounting disc 7, the grinding wheel in the mounting disc 7 is driven to rotate, and then the grinding wheel is brought into contact with the grinding stone for dressing work;

[0066] S3, when the fixed box 41 rotates toward the mounting plate 7, another set of fixed boxes 41 will overlap with another set of grinding stones on the feeding plate 51, and the pushing mechanism 6 will push another set of grinding stones onto the fixed box 41 again. The other set of grinding stones can be grinding stones of different meshes or different types, which is convenient for dressing work according to the dressing process of the grinding wheel;

[0067] During operation, grinding stones of different mesh sizes are first placed in the feeding tray 51 in sequence, clamped by the clamping block 56 in the feeding tray 51, and then the main shaft 31 is used to drive the dressing tray 3 and the feeding tray 51 to rotate. During the rotation, the fixed box 41 on the dressing tray 3 and the notch 57 on the feeding tray 51 slowly overlap in parallel. At the same time, when the feeding tray 51 rotates, the bidirectional screw 62 in the pushing box 61 is driven to rotate, so that the pushing head 68 is used to push the grinding stone into the fixed box 41 when the notch 57 overlaps with the fixed box 41. After the grinding stone is pushed into the fixed box 41, it drives the dressing tray 3 to rotate again, and the fixed box 41 is driven to rotate during the rotation. When the grinding stone reaches the bottom of the mounting plate 7, the grinding wheel in the mounting plate 7 is driven to rotate, and then the grinding wheel is brought into contact with the grinding stone for dressing work. When the fixing box 41 rotates toward the mounting plate 7, another set of fixing boxes 41 will overlap with another set of grinding stones on the feeding plate 51, and the pushing mechanism 6 will push another set of grinding stones onto the fixing box 41 again. The other set of grinding stones can be grinding stones of different mesh sizes or different types, which is convenient for dressing work according to the dressing process of the grinding wheel.

[0068] The working principle of the present invention is as follows: after the grinding stone is installed on the feeding plate 51, the main shaft 31 on the rotating sliding base 2 is rotated, and then the connecting belt 33 is used to drive the secondary shaft 53 to rotate, that is, the trimming plate 3 and the feeding plate 51 are driven to rotate at the same time, and the feeding plate 51 and the trimming plate 3 rotate in opposite directions, the trimming plate 3 rotates counterclockwise, and the feeding plate 51 rotates clockwise. When the trimming plate 3 rotates counterclockwise, it will drive one group of fixed boxes 41 close to the feeding plate 51. When the feeding plate 51 rotates counterclockwise, it will drive the grinding stone in the notch 57 close to the fixed box 41. When the fixed box 41 and the grinding stone overlap in parallel, the grinding stone is pushed into the fixed box 41 by the pushing head 68 in the pushing box 61. The pushing method is as follows: when the feeding plate 51 rotates, the teeth 52 at the bottom of the feeding plate 51 will be used to drive the pushing gear 621 on the pushing box 61 to rotate. When the push gear 621 rotates, the bidirectional screw rod 62 inside the push box 61 will be driven to rotate. When the bidirectional screw rod 62 rotates, the threaded disk 63 will be driven to move toward the grinding stone, and at the same time, the telescopic column 65 and the push head 68 will be driven to approach the grinding stone and abut against the grinding stone. Under the slow rotation of the feed plate 51, the push head 68 is used to slowly push the grinding stone into the fixed box 41. At the same time, a telescopic spring 67 is provided in the telescopic column 65. Since the push head 68 may abut against the inner wall of the feed plate 51 when the feed plate 51 rotates, in order to avoid hard contact between the push head 68 and the feed plate 51, the telescopic spring 67 will be squeezed when the push head 68 contacts the feed plate 51. When the notch 57 on the feed plate 51 is parallel to the fixed box 41, the push head 68 will pass through the notch 54 and contact the grinding stone again, thereby pushing the grinding stone into the fixed box 41.

[0069] When the grinding stone is pushed onto the bottom plate 411 in the fixed box 41, the dressing disc 3 is driven to rotate again. When rotating, the dressing disc 3 will drive the fixed box 41 to reach the lower rack 32, and make the lower gear 491 at the bottom of the fixed box 41 mesh with the lower rack 32. At the same time, the fixed box 41 on the dressing disc 3 is rotated to the bottom of the mounting disc 7. During the movement of the fixed box 41, the lower gear 491 is driven to rotate by the lower rack 32, and then the transmission shaft 49 is used to drive the rotating shaft 42 and the crown gear 43 inside the fixed box 41 to rotate, and then the crown gear 43 is used to drive the driven gear 46 to rotate, thereby driving the fixed screw 45 to rotate. When the fixed screw 45 rotates, it will drive the two sets of moving plates 47 moves toward the grindstone, and then the grindstone is fixed by the rubber pad 48, wherein the rubber pad 48 is a flexible material. In order to adapt to different types of grindstones, the rubber pad 48 will be squeezed by the grindstone when it contacts the grindstone. When encountering a larger grindstone, the rubber pad 48 is squeezed deeper, and when encountering a smaller grindstone, the rubber pad 48 is squeezed shallower, and the grindstone and the rubber pad 48 will not be damaged during the squeezing process, and the rubber pad 48 can be restored to its original state after the squeezing is completed. At the same time that the dressing disk 3 drives the grindstone to rotate to the bottom of the mounting disk 7, another group of grindstones on the feeding disk 51 are also pushed by the push head 68 to another group of fixed boxes 41, so that different grindstones can be used according to the dressing process of the grinding wheel.
