Description

Technical Field

[0001] The invention relates to the field of ceramic super-hard abrasive tools, in particular to an abrasive layer removal system for ceramic super-hard abrasive tools. Background Art

[0002] Ceramic superabrasive grinding tools are usually composed of a grinding tool base, a bonding layer and an abrasive layer. The grinding tool base is generally a disc-like part made of metal. The abrasive layer is generally a whole abrasive ring or an abrasive ring spliced together by several segments. The abrasive layer is solidified on the grinding tool base through a bonding layer. The bonding layer is made of liquid resin glue that is air-dried and solidified. Since the abrasive layer part of the ceramic superabrasive grinding tool is involved in the grinding process, it is also this part that is consumed. The grinding tool base only plays the role of supporting the abrasive layer and is not consumed during use. Therefore, superabrasive grinding tools often need to recycle the grinding tool base after the abrasive layer is worn out. At this time, the residual abrasive layer needs to be removed.

[0003] Currently, the abrasive layer is usually removed by heating the bonding layer and the abrasive layer, and then scraping the abrasive layer and the bonding layer together with a knife. Most bonding layers use resin adhesives, and the softening temperature of these resin adhesives is between 58 and 93 degrees Celsius. When encountering abrasive tools of different specifications, the inner hole diameters of the abrasive tools are also different. This results in an abrasive layer removal device of one specification being able to remove only abrasive tools of one specification. If abrasive tools of different inner hole diameters are encountered, the entire abrasive tool cannot be fixed, resulting in the mechanical scraping of the abrasive layer, which greatly increases the labor.

[0004] In view of this, the present invention proposes a ceramic super-hard abrasive grinding tool abrasive layer removal system to solve the above technical problems. Summary of the Invention

Specific implementation mode

[0032] Aiming at the deficiencies of the prior art, the present invention provides a system for removing the abrasive layer of a ceramic super-hard abrasive grinding tool, and solves the technical problem that: when the existing abrasive layer removal system removes the abrasive layer, the inner holes of grinding tools with different specifications are different, resulting in the inability to fix the whole grinding tool.

[0033] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0034] Please refer to Figures 1 to 8 , the present invention provides a technical solution:

[0035] A system for removing the abrasive layer of a ceramic super-hard abrasive grinding tool, as Figures 1 to 2 shown, includes a support plate 1; anti-slip feet 2, and the lower end of the support plate 1 is uniformly and fixedly connected with anti-slip feet 2; an abrasive groove 9, and the middle part of the upper end of the support plate 1 is fixedly connected with an abrasive groove 9;

[0036] Storage battery 6, the upper end of the support plate 1 is fixedly connected with a storage battery 6 on the left side of the abrasive groove 9; Switch 7, the front end of the storage battery 6 is fixedly connected with a switch 7; U-shaped high-frequency heater 8, the upper end of the storage battery 6 is fixedly connected with a U-shaped high-frequency heater 8; Cutting knife cylinder 3, the upper end of the support plate 1 is fixedly connected with a cutting knife cylinder 3 on the right side of the abrasive groove 9; Adjusting bolt 5, the right side of the cutting knife cylinder 3 is movably connected with an adjusting bolt 5; Straight tooth cutter 4, a straight tooth cutter 4 is installed inside the cutting knife cylinder 3, and the straight tooth cutter 4 extends to the left side of the cutting knife cylinder 3 and is located inside the abrasive groove 9; Support frame 10, the upper end of the support plate 1 is fixedly connected with a support frame 10 at the rear end of the abrasive groove 9; Motor 11, the front end of the support frame 10 is fixedly connected with a motor 11; Rotating shaft 12, the lower end of the motor 11 is movably connected with a rotating shaft 12; Limiting plate 14, the lower part of the side surface of the rotating shaft 12 is threadedly connected with a limiting plate 14; Grinding tool 13, the surface of the rotating shaft 12 is clamped with a grinding tool 13 at the upper end of the limiting plate 14;

[0037] An expansion mechanism 15 is arranged on the rotating shaft 12;

[0038] By arranging the expansion mechanism 15 on the rotating shaft 12, the abrasive layer of the grinding tool 13 with different inner hole diameters can be stably removed.

[0039] During operation, first unscrew the limiting plate 14, then movably sleeved the grinding tool 13 on the side surface of the rotating shaft 12. After sleeving, tighten the limiting plate 14 to ensure that the grinding tool will not fall down. After sleeving, press the switch 7. After pressing the switch 7, the U-shaped high-frequency heater 8 electrically connected to the storage battery 6 starts to heat the abrasive layer and the bonding layer of the grinding tool, and the motor 11 starts to rotate to drive the rotating shaft 12. Then, turn the adjusting bolt 5 on the right side of the cutting knife cylinder 3. The adjusting bolt 5 is threadedly connected with the cutting knife cylinder 3, the straight tooth cutter 4 is slidably connected with the cutting knife cylinder, and the straight tooth cutter 4 is rotatably connected with the adjusting bolt 5. After turning the adjusting bolt 5, the straight tooth cutter 4 moves from the right side inside the cutting knife cylinder 3 to the left side of the cutting knife cylinder 3, and the straight tooth cutter 4 extending out of the cutting knife cylinder 3 moves into the abrasive groove 9. Adjust the distance between the straight tooth cutter 4 and the abrasive layer of the grinding tool to facilitate more effective scraping of the abrasive layer and the bonding layer of the grinding tool. Arranging the expansion mechanism 15 on the rotating shaft 12 can stably fix grinding tools of different specifications and more stably remove the abrasive layers of grinding tools with different inner hole diameters.

[0040] As an implementation manner of the present invention, such as Figure 3 And Figure 8As shown, the expansion mechanism 15 includes a connecting column 155; a connecting column 155, the lower end of the rotating shaft 12 is fixedly connected to the connecting column 155; a connecting block 159, the lower end of the connecting column 155 is fixedly connected to the connecting block 159; a sliding groove 1511, the lower end of the rotating shaft 12 is provided with a sliding groove 1511; a bearing 151, the interior of the sliding groove 1511 is movably connected to the bearing 151; a limit block 1512, the two sides of the outer ring of the bearing 151 are fixedly connected to the limit block 1512; an elastic platinum sheet 1513, the two sides of the interior of the sliding groove 1511 are fixedly connected to the elastic platinum sheet 1513; a rotating rod 152, the lower end of the inner ring of the bearing 151 is fixedly connected to the rotating rod 152, and the rotating rod 152 passes through the connecting block 159 and extends to the connecting block 159; twist the handle 16, the lower end of the rotating rod 152 is fixedly connected to the twist handle 16; the fixed block 153, the lower end of the rotating shaft 12 is located on both sides of the rotating rod 152 and is fixedly connected to the fixed block 153; the long gear 158, the long gear 158 is fixedly connected to the upper side surface of the rotating rod 152; the gear rod 154, the front and rear ends of the long gear 158 are meshed with the gear rod 154; the expansion arc plate 157, the gear rod 154 is clamped in the inside of the fixed block 153, and the side of the gear rod 154 away from the meshing is fixedly connected to the expansion arc plate 157; the outer gear 156, the outer gear 156 is fixedly connected to the lower side surface of the rotating rod 152; the internal gear 1561, the internal gear 1561 is fixedly connected to the inside of the connecting block 159;

[0041] During operation, first, the abrasive tool is put on the outer surface of the expansion arc plate 157, and then the handle 16 is pulled downward by hand. When the handle 16 is turned downward, the rotating rod 152 is driven to move downward, and the rotating rod 152 drives the outer gear 156, the long gear 158, the bearing 151 and the limit block 1512 to move downward. When the outer gear 156 and the inner gear 1561 are completely staggered, the limit block 1512 is separated from the elastic platinum sheet 1513, and then the handle 16 is turned clockwise. When the handle 16 is turned clockwise, the rotating rod 152 is driven to rotate clockwise, and the rotating rod 152 drives the long gear 158 to rotate clockwise. While 58 rotates, the gear rod 154 engaged with the long gear 158 begins to move away from the rotating rod 152. While the gear rod 154 moves away from the rotating rod 152, it drives the expansion arc plate 157 to move away from the rotating rod 152. When the expansion arc plate 157 is tightly attached to the inner hole of the grinding tool 13, stop twisting the twisting handle 16 and drag the twisting handle 16 upward. When the limit block 1512 is engaged with the elastic platinum sheet, 1513 stops dragging the twisting handle 16 upward. An expansion mechanism 15 is set on the rotating shaft 12, which can stably fix grinding tools 13 with different inner holes, thereby solving the problem that the abrasive layer removal system cannot fix grinding tools 13 of different specifications.

[0042] As an embodiment of the present invention, as Figure 3 shown, the outer surface of the expansion arc plate 157 is a soft magnetic sheet 17, and the inner surface of the expansion arc plate 157 is a tensile rubber 18;

[0043] During operation, at the moment when the expansion arc plate 157 contacts the inner hole of the grinding tool 13, the soft magnetic sheet 17 on the outer surface of the expansion arc plate 157 adsorbs on the surface of the inner hole of the grinding tool 13, greatly increasing the friction between the expansion arc plate 157 and the surface of the inner hole of the grinding tool 13. When the rotating shaft 12 rotates, it effectively prevents the friction between the expansion arc plate 157 and the surface of the inner hole of the grinding tool from being too small to fix the grinding tool. The inner surface of the expansion arc plate 157 is a tensile rubber 18, which can cooperate with the soft magnetic sheet 17 to make close contact with the inner hole of the grinding tool 13 and play a sealing role. It should be noted that the base of the grinding tool 13 is made of iron or iron-based material.

[0044] As an embodiment of the present invention, as Figure 7 shown, an extrusion mechanism 19 is provided at the upper end of the side surface of the rotating shaft 12 located in the expansion mechanism 15. The extrusion mechanism 19 includes a highly deformable rubber 191. The highly deformable rubber 191 is fixedly connected to the side surface of the rotating shaft 12 at the upper end of the expansion mechanism 15. An annular spring 192 and a counterweight block 193 are provided. The annular spring 192 is uniformly fixedly connected with the counterweight block 193 inside.

[0045] During operation, when the rotating shaft 12 rotates, the highly deformable rubber 191 and the annular spring 192 start to extend along the centrifugal trajectory under the action of centrifugal force. The highly deformable rubber 191 and the annular spring 192 are rapidly deformed and extended under the action of the gravity of the counterweight block 193 itself and the centrifugal speed. After being heated by the U-shaped high-frequency heater 8 and then scraped off by the straight-tooth cutter 4 and extruded onto the mixture of the abrasive layer and the adhesive layer at the upper end of the grinding tool 13, the outermost periphery of the expanded highly deformable rubber 191 pushes the mixture of the abrasive layer and the adhesive layer away from the upper end of the grinding tool 13. After scraping, press the switch 7, the U-shaped high-frequency heater 8 stops heating and the motor 11 stops rotating. As the rotating shaft 12 stops rotating, the highly deformable rubber 191 and the annular spring 192 return to their deformed states. It should be noted that the material of the highly deformable rubber 191 is ethylene propylene rubber and can be used for a long time below 120 degrees. The maximum heating temperature of the U-shaped high-frequency heater 8 is 93 degrees.

[0046] As an embodiment of the present invention, as Figure 3 shown, the diameter of the lower end inside the sliding groove 1511 is smaller than the diameter of the bearing 151, and the diameter of the lower end inside the sliding groove 1511 is larger than the diameter of the rotating rod 152;

[0047] During operation, the diameter of the lower end of the sliding groove 1511 is smaller than the diameter of the bearing 151, which can prevent the rotating rod 152 and the bearing 151 from being pulled out as a whole when the handle 16 is pulled and turned toward the lower end, thereby affecting the normal operation of the expansion mechanism 15. The diameter of the lower end of the sliding groove 1511 is larger than the diameter of the rotating rod 152, which facilitates the rotating rod 152 to move to the lower end without being stuck, and the lower and upper ends move normally into the sliding groove 1511.

[0048] As an embodiment of the present invention, Figure 3 As shown, the teeth at the upper and lower ends of the outer gear 156 and the inner gear 1561 are sloped;

[0049] During operation, the teeth at the upper and lower ends of the outer gear 156 and the inner gear 1561 are sloped, which can prevent the outer gear 156 and the inner gear 1561 from getting stuck when they first come into contact.

[0050] As an embodiment of the present invention, Figure 7 As shown, the deformation recovery force of the high-deformation rubber 191 and the restoring force of the annular spring 192 are greater than the friction force of the annular spring 192, the counterweight 193 and the high-deformation rubber 191 on the upper end surface of the mold 13;

[0051] During operation, only when the deformation recovery force of the high-deformation rubber 191 and the recovery force of the annular spring 192 are greater than the friction force of the annular spring 192, the counterweight 193 and the high-deformation rubber 191 on the upper end surface of the mold 13, can the annular spring 192, the counterweight 193 and the high-deformation rubber 191 recover their deformation and return to their original position when the rotating shaft 12 stops rotating.

[0052] As an embodiment of the present invention, Figure 3 As shown, the height of the outer gear 156 and the inner gear 1561 is equal to the height of the sliding groove 1511;

[0053] During operation, only when the height of the outer gear 156 and the inner gear 1561 is equal to the height of the sliding groove 1511, can the handle 16 be turned to pull the rotating rod 152 toward the lower end, and then the arc plate 157 can be expanded by turning the handle 16 clockwise to move away from the rotating rod 152.

[0054] As an embodiment of the present invention, Figure 7 As shown, the maximum deformation length of the high-deformation rubber 191 is less than or equal to the radius of the mold 13;

[0055] During operation, when the maximum deformation length of the highly deformable rubber 191 is less than or equal to the radius of the grinding tool 13, the deformed highly deformable rubber 191 will not get stuck in the gap between the U-shaped high-frequency heater 8 and the grinding tool 13 because the length of the deformed highly deformable rubber 191 is greater than the radius of the grinding tool 13. It should be noted that the internal height of the U-shaped high-frequency heater 8 is greater than the thickness of the grinding tool 13 plus the thickness of the deformed highly deformable rubber 191.

[0056] As an embodiment of the present invention, as Figures 5 to 6 shown, the connection position between the gear rod 154 and the expansion arc plate 157 is a strong magnet;

[0057] During operation, the connection position between the gear rod 154 and the expansion arc plate 157 is a strong magnet, which can enhance the suction force of the expansion arc plate 157 on the inner hole surface of the grinding tool and further increase the friction between the expansion arc plate 157 and the inner hole of the grinding tool 13.

[0058] Working principle:

[0059] When working, first unscrew the limit plate 14, then sleeved the grinding tool 13 on the side surface of the rotating shaft 12. After the sleeving is completed, tighten the limit plate 14 to ensure that the grinding tool will not fall down. After the sleeving is completed, press the switch 7. After pressing the switch 7, the U-shaped high-frequency heater 8 electrically connected to the storage battery 6 starts to heat the abrasive layer and the bonding layer of the grinding tool, and the motor 11 starts to rotate to drive the rotating shaft 12. Then, turn the adjusting bolt 5 on the right side of the cutting tool cylinder 3. The straight-tooth cutter 4 is slidably connected to the cutting tool cylinder, and the straight-tooth cutter 4 is rotatably connected to the adjusting bolt 5. After turning the adjusting bolt 5, the straight-tooth cutter 4 moves from the right side inside the cutting tool cylinder 3 to the left side of the cutting tool cylinder 3, and the straight-tooth cutter 4 extending out of the cutting tool cylinder 3 moves into the abrasive groove 9 to adjust the distance between the straight-tooth cutter 4 and the abrasive layer of the grinding tool, which is convenient for more effectively scraping the abrasive layer and the bonding layer of the grinding tool. An expansion mechanism 15 is provided on the rotating shaft 12 to stably fix grinding tools of different specifications and more stably remove the abrasive layer of grinding tools with different inner hole diameters; first, sleeved the grinding tool on the outer surface of the expansion arc plate 157, and then pull the turning handle 16 downward by hand. While the turning handle 16 is turned downward, it drives the rotating rod 152 to move downward. The rotating rod 152 drives the outer gear 156, the long gear 158, the bearing 151 and the limit block 1512 to move downward. While the outer gear 156 and the inner gear 1561 are completely staggered, the limit block 1512 disengages from the elastic platinum sheet 1513. Then, start to turn the turning handle 16 clockwise. While the turning handle 16 is turned clockwise, the turning handle 16 drives the rotating rod 152 to rotate clockwise. The rotating rod 152 drives the long gear 158 to rotate clockwise. While the long gear 158 is rotating, the gear rod 154 engaged with the long gear 158 starts to move away from the rotating rod 152. While the gear rod 154 moves away from the rotating rod 152, it drives the expansion arc plate 157 to move away from the rotating rod 152. When the expansion arc plate 157 is in close contact with the inner hole of the grinding tool 13, stop turning the turning handle 16 and pull the turning handle 16 upward. When the limit block 1512 is clamped on the elastic platinum sheet 1513, stop pulling the turning handle 16 upward. An expansion mechanism 15 is provided on the rotating shaft 12, which can stably fix grinding tools 13 with different inner holes and solve the problem that the abrasive layer removal system cannot fix grinding tools 13 of different specifications; at the moment when the expansion arc plate 157 contacts the inner hole of the grinding tool 13, the soft magnetic sheet 17 on the outer surface of the expansion arc plate 157 adsorbs on the surface of the inner hole of the grinding tool 13, greatly increasing the friction force between the expansion arc plate 157 and the surface of the inner hole of the grinding tool 13, effectively preventing the friction force between the expansion arc plate and the surface of the inner hole of the grinding tool from being too small to fix the grinding tool when the rotating shaft 12 rotates. The inner surface of the expansion arc plate 157 is a stretching rubber 18, which can cooperate with the soft magnetic sheet 17 to make a tight contact with the inner hole of the grinding tool 13 and play a sealing role. It should be noted that the base body of the grinding tool 13 is made of iron or iron-based material;When the rotating shaft 12 rotates, the highly deformable rubber 191 and the annular spring 192 start to extend along the centrifugal trajectory under the action of centrifugal force. The highly deformable rubber 191 and the annular spring 192 rapidly deform and extend under the action of the gravity of the counterweight 193 itself and the centrifugal speed. After being heated by the U-shaped high-frequency heater 8 and then scraped off by the straight-tooth cutter 4 and squeezed onto the mixture of the abrasive layer and the adhesive layer at the upper end of the mold 13, the outermost periphery of the expanded highly deformable rubber 191 pushes the mixture of the abrasive layer and the adhesive layer away from the upper end of the mold 13. After scraping, press the switch 7, the U-shaped high-frequency heater 8 stops heating and the motor 11 stops rotating. As the rotating shaft 12 stops rotating, the highly deformable rubber 191 and the annular spring 192 recover their deformation. It should be noted that the material of the highly deformable rubber 191 is ethylene propylene rubber and can be used for a long time below 120 degrees. The maximum heating temperature of the U-shaped high-frequency heater 8 is 93 degrees; the diameter of the lower end inside the sliding groove 1511 is smaller than the diameter of the bearing 151, which can prevent the rotating rod 152 and the bearing 151 from being pulled out as a whole when pulling the handle 16 downward, thus affecting the normal operation of the expansion mechanism 15. The diameter of the lower end inside the sliding groove 1511 is larger than the diameter of the rotating rod 152, which is convenient for the rotating rod 152 to move downward without being stuck and enter the sliding groove 1511 normally; the teeth at the upper and lower ends of the external gear 156 and the internal gear 1561 are in a slope shape, which can prevent the external gear 156 and the internal gear 1561 from being stuck when they first come into contact; only when the deformation recovery elastic force of the highly deformable rubber 191 and the recovery elastic force of the annular spring 192 are greater than the frictional force of the annular spring 192, the counterweight 193 and the highly deformable rubber 191 on the upper surface of the mold 13 can the annular spring 192, the counterweight 193 and the highly deformable rubber 191 recover their deformation and return to the original position when the rotating shaft 12 stops rotating; only when the height of the external gear 156 and the internal gear 1561 is equal to the height of the sliding groove 1511 can the expansion arc plate 157 move away from the rotating rod 152 when the handle 16 is pulled downward to rotate the rotating rod 152 and then the handle 16 is rotated clockwise; when the maximum deformation length of the highly deformable rubber 191 is less than or equal to the radius of the mold 13, the deformed highly deformable rubber 191 will not be stuck in the gap between the U-shaped high-frequency heater 8 and the mold 13 because the length of the deformed highly deformable rubber 191 is greater than the radius of the mold 13. It should be noted that the internal height of the U-shaped high-frequency heater 8 is greater than the thickness of the mold 13 plus the thickness of the deformed highly deformable rubber 191; the connection position between the gear rod 154 and the expansion arc plate 157 is a strong magnet, which can strengthen the suction force of the expansion arc plate 157 on the inner hole surface of the mold and further increase the frictional force between the expansion arc plate 157 and the inner hole of the mold 13.;
