Description

Technical Field

[0001] This invention relates to the field of diamond composite cutting tool grinding technology, and in particular to a high-speed grinding and repair device for diamond composite cutting tools. Background Technology

[0002] Diamond composite cutting teeth are a type of cutting teeth that use a new type of diamond and cemented carbide composite teeth. These cutting teeth have cemented carbide diameter-protecting teeth distributed on the outer side of the cutting tooth head, which enhances the wear resistance of the cutting tooth head, has a good diameter-protecting effect, and can effectively protect the cutting tooth and extend its overall service life.

[0003] Currently, after long-term drilling, the surface of diamond composite cutting tools will be worn. At this time, it is necessary to grind and repair the surface. However, due to the special shape and many specifications of diamond composite cutting tools, it is necessary to equip multiple feed path molds to grind and repair diamond composite cutting tools of different specifications, which will greatly increase the production cost. Therefore, manual grinding is usually the only option, which is not only low in grinding accuracy but also inefficient.

[0004] Based on this, we propose a high-speed grinding and repair device for diamond composite cutting teeth. Summary of the Invention

The limit rod is located between two straight guide rails, and the side wall of the limit rod is in contact with the side wall of the straight guide rail. The mounting shaft is fixedly sleeved with a torsion spring. The two ends of the torsion spring are fixedly connected to the upper end of the grinding table and the lower end of the swing arm respectively.

[0009] A drive mechanism is installed on the workbench.

[0010] Preferably, the drive mechanism includes a mounting plate fixedly connected to the upper end of the worktable, a rotating shaft rotatably connected to the side wall of the mounting plate, a servo motor fixedly connected to the upper end of the mounting plate via a bracket, the output end of the servo motor being fixedly connected to the rotating shaft, a reciprocating screw rotatably connected to the inner wall of the groove, and the side wall of the reciprocating screw being threadedly connected to the moving block.

[0011] Preferably, the drive mechanism further includes a drive wheel fixedly connected to the side wall of the rotating shaft, one end of the reciprocating screw passes through the side wall of the stroke seat and is fixedly connected to a driven wheel, and the drive wheel and the driven wheel are connected by a synchronous belt.

[0012] Preferably, a traveling mechanism is installed in the slide groove. The traveling mechanism includes a lead screw rotatably connected to the inner wall of the slide groove. The side wall of the lead screw is threadedly connected to the slider. An installation groove is provided at the upper end of the worktable. An installation rod is rotatably connected to the inner wall of the installation groove. A first bevel gear is fixedly connected to one end of the installation rod. A second bevel gear is fixedly connected to one end of the lead screw, which extends into the installation groove. The first bevel gear and the second bevel gear are meshed together.

[0013] Preferably, the traveling mechanism further includes a sector gear fixedly connected to the side wall of the rotating shaft, and one end of the mounting rod passes through the side wall of the worktable and is fixedly connected to a first gear that cooperates with the sector gear.

[0014] Preferably, a tensioning mechanism is installed on the mounting plate. The tensioning mechanism includes a vertical groove formed on the side wall of the mounting plate. A vertical block is slidably connected to the inner wall of the vertical groove. A tensioning wheel is rotatably connected to the side wall of the vertical block via a pin. The tensioning wheel, the driving wheel, and the driven wheel are connected by a synchronous belt. A guide rod is fixedly connected to the inner wall of the vertical groove. The side wall of the guide rod is slidably connected to the vertical block. A spring is sleeved on the side wall of the guide rod. The two ends of the spring are fixedly connected to the top of the vertical groove and the upper end of the vertical block, respectively.

[0018] The present invention has the following beneficial effects:

[0019] 1. By setting up a grinding mechanism and a drive mechanism, and by starting the servo motor, the cutting tool can be driven to move along the shape of the diamond composite cutting tooth, thereby grinding it. This can achieve rapid grinding and repair of diamond composite cutting teeth, which is more efficient than manual grinding.

[0020] 2. By setting an adjustment mechanism and adjusting the inclined guide rail and the inclined angle of the guide rail, the inclined movement angle of the blade can be adjusted, which can grind the conical surface of diamond composite cutting teeth at different angles. Therefore, it can be used for diamond composite cutting teeth of different specifications, without the need to equip multiple tool travel track molds, thus reducing production costs.

[0021] 3. By setting up a travel mechanism, the cutting tool can intermittently travel a unit distance to the diamond composite cutting tooth during the grinding process to perform multiple grinding operations. Firstly, since the width of the cutting tool is fixed, the grinding thickness of the diamond composite cutting tooth each time is limited, which avoids excessive overlap between the cutting tool and the cross section of the diamond composite cutting tooth in a single operation, resulting in excessive force on the cutting tool surface during grinding and thus causing the cutting tool to break. Secondly, since the cutting tool can travel freely, it can grind diamond composite cutting teeth of different diameters, thus having a wider range of applications. Attached Figure Description

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Reference Figure 1 - Figure 8 A high-speed grinding and repair device for diamond composite cutting teeth includes a worktable 1, a groove 2 is provided on the upper end of the worktable 1, and a travel seat 4 is slidably connected to the inner wall of the groove 2.

[0033] The grinding mechanism includes a groove 5 formed on the upper end of the travel seat 4. A movable block 6 is slidably connected to the inner wall of the groove 5. A grinding table 7 is fixedly connected to the upper end of the movable block 6. Two mounting shafts 8 are symmetrically rotatably connected to the upper end of the grinding table 7. A rocker arm 9 is fixedly connected to the side wall of each of the two mounting shafts 8. A tool holder 10 is rotatably connected to the upper end of the rocker arm 9. A cutting tool 11 is fixedly connected to the side wall of the tool holder 10. Two straight guide rails 12 are fixedly connected to the upper end of the travel seat 4 via a fixed shaft. Two rotating rods 13 are rotatably connected to the upper end of the travel seat 4. The two rotating rods 13 are respectively set through the upper end of the two straight guide rails 12, and the side walls of the two rotating rods 13 are fixedly connected to... There is an inclined guide rail 14, and an adjusting guide rail 15 is slidably connected to the inner wall of the inclined guide rail 14. Two L-shaped guide rails 16 are fixedly connected to the upper end of the stroke seat 4 through a fixed shaft. Two connecting guide rails 17 are slidably connected to the inner walls of the two L-shaped guide rails 16. The other ends of the two connecting guide rails 17 are rotatably connected to the two adjusting guide rails 15 respectively. One end of the tool holder 10 is rotatably connected to a limit rod 18. The limit rod 18 is located between two straight guide rails 12, and the side wall of the limit rod 18 is in contact with the side wall of the two straight guide rails 12. A torsion spring 44 is fixedly sleeved on the mounting shaft 8. The two ends of the torsion spring 44 are fixedly connected to the upper end of the grinding table 7 and the lower end of the swing rod 9 respectively.

[0034] A drive mechanism is installed on workbench 1.

[0035] The drive mechanism includes a mounting plate 19 fixedly connected to the upper end of the worktable 1. A rotating shaft 20 is rotatably connected to the side wall of the mounting plate 19. A servo motor 21 is fixedly connected to the upper end of the mounting plate 19 via a bracket. The output end of the servo motor 21 is fixedly connected to the rotating shaft 20. A reciprocating screw 22 is rotatably connected to the inner wall of the groove 5. The side wall of the reciprocating screw 22 is threadedly connected to the moving block 6.

[0036] The drive mechanism also includes a drive wheel 23 fixedly connected to the side wall of the rotating shaft 20, and a driven wheel 24 fixedly connected to one end of the reciprocating screw 22 through the side wall of the stroke seat 4. The drive wheel 23 and the driven wheel 24 are connected by a synchronous belt.

[0037] One end of the rotating shaft 20 passes through the side wall of the mounting plate 19 and is fixedly connected to a fixed cylinder 41. Two electric push rods 42 are symmetrically fixedly connected to the side wall of the fixed cylinder 41. The movable ends of the two electric push rods 42 pass through the inner wall of the fixed cylinder 41 and are fixedly connected to a fixed plate 43.

[0038] Furthermore, the servo motor 21 is activated, driving the rotating shaft 20 to rotate, which in turn drives the driving wheel 23 to rotate, which in turn drives the driven wheel 24 to rotate, thereby driving the reciprocating screw 22 to rotate, causing the moving block 6 to slide on the inner wall of the groove 5, which in turn drives the grinding table 7 to move, and drives the tool holder 10 and the cutting blade 11 to move. At this time, the rotation of the rotating shaft 20 will synchronously drive the fixed cylinder 41 to rotate, thereby driving the fixed diamond composite cutting tooth to rotate. The horizontally moving cutting blade 11 contacts the surface of the rotating diamond composite cutting tooth, and will grind it. The movement of the tool holder 10 will synchronously drive the limit rod 18 to move. The limit rod 18 will first move within the straight guide rail 12 (e.g., Figure 5 As shown), at this time, the blade 11 moves linearly, which can grind the cylindrical head of the diamond composite cutting tooth. Then, the limit rod 18 enters the inclined guide rail 14 and the adjusting guide rail 15, which will cause the tool holder 10 to swing to the right (as shown). Figure 5 As shown), at this time, the tool holder 10 will simultaneously drive the blade 11 to move diagonally to the right, and drive the two mounting shafts 8 to rotate clockwise (as shown). Figure 5 As shown), the blade 11 will travel along the conical surface of the diamond composite cutting tooth and grind its conical surface. Finally, when the limiting rod 18 moves into the connecting guide rail 17 and the L-shaped guide rail 16, the mounting shaft 8 will rotate and reset under the action of the torsion spring 44, thereby driving the blade 11 to reset and travel in a straight line again, thus grinding the cylindrical surface of the diamond composite cutting tooth. In this way, the entire travel trajectory of the blade 11 completely conforms to the special shape surface of the diamond composite cutting tooth, which can realize the rapid grinding and repair of the diamond composite cutting tooth.

[0039] A traveling mechanism is installed inside the slide 2. The traveling mechanism includes a lead screw 25 rotatably connected to the inner wall of the slide 2. The side wall of the lead screw 25 is threadedly connected to the slider 3. An installation groove 26 is provided at the upper end of the worktable 1. An installation rod 27 is rotatably connected to the inner wall of the installation groove 26. A first bevel gear 28 is fixedly connected to one end of the installation rod 27. One end of the lead screw 25 extends into the installation groove 26 and is fixedly connected to a second bevel gear 29. The first bevel gear 28 and the second bevel gear 29 are meshed together.

[0040] The traveling mechanism also includes a sector gear 31 fixedly connected to the side wall of the rotating shaft 20, and a first gear 30 that cooperates with the sector gear 31 is fixedly connected to one end of the mounting rod 27 through the side wall of the worktable 1.

[0041] Furthermore, when the cutting tool 11 reaches its end, it will move in the opposite direction to reset. When the cutting tool 11 is fully reset, the sector gear 31 will rotate to mesh with the first gear 30. At this time, the sector gear 31 will drive the first gear 30 to rotate, which in turn will drive the mounting rod 27 to rotate, which will drive the first bevel gear 28 to rotate, which will drive the second bevel gear 29 to rotate, which will drive the lead screw 25 to rotate, causing the slider 3 to slide in the slide groove 2, which in turn will drive the travel seat 4 to move, which will drive the grinding table 7 to move, which will then drive the cutting tool 11 to travel a unit distance towards the diamond composite cutting tooth. Then it can be ground a second time, and so on, until the surface damage of the diamond composite cutting tooth is repaired by grinding. The reason why the blade 11 performs multiple grindings by intermittently traveling one unit distance is that the width of the blade 11 is fixed, and the grinding thickness of the diamond composite cutting tooth each time is limited, so as to avoid the blade 11 overlapping the cross section of the diamond composite cutting tooth too much in a single time, which would cause excessive force on the surface of the blade 11 during grinding and thus cause the blade 11 to break. Secondly, since the blade 11 can move freely, it can grind diamond composite cutting teeth of different diameters, and has a wider range of applications.

[0042] A tensioning mechanism is installed on the mounting plate 19. The tensioning mechanism includes a vertical groove 32 formed on the side wall of the mounting plate 19. A vertical block 33 is slidably connected to the inner wall of the vertical groove 32. A tensioning wheel 34 is rotatably connected to the side wall of the vertical block 33 via a pin. The tensioning wheel 34, the driving wheel 23, and the driven wheel 24 are connected by a synchronous belt. A guide rod 35 is fixedly connected to the inner wall of the vertical groove 32. The side wall of the guide rod 35 is slidably connected to the vertical block 33. A spring 36 is sleeved on the side wall of the guide rod 35. The two ends of the spring 36 are fixedly connected to the top of the vertical groove 32 and the upper end of the vertical block 33, respectively.

[0043] Furthermore, when the driven wheel 24 moves, the vertical block 33 will move under the action of the spring 36, driving the tension wheel 34 to move, so that the synchronous belt always remains taut, ensuring the effective transmission of power.

[0044] An adjustment mechanism is installed on the travel seat 4. The adjustment mechanism includes an adjustment rod 37 rotatably connected to the upper end of the travel seat 4. A second gear 38 is fixedly connected to the side wall of the adjustment rod 37. A third gear 39 is fixedly connected to the side wall of each of the two rotating rods 13. The third gear 39 is meshed with the second gear 38.

[0045] The upper end of the adjusting rod 37 is fixedly connected to a nut 40.

[0046] Furthermore, by using an external hexagonal wrench to engage the nut 40, the adjusting rod 37 can be rotated, which in turn rotates the second gear 38, thereby rotating the third gear 39. This, in turn, causes the two rotating rods 13 to rotate synchronously, causing the inclined guide rail 14 and the adjusting guide rail 15 to rotate synchronously around the center of the rotating rod 13. This adjusts the angle of the inclined guide rail 14 and the adjusting guide rail 15. At this time, the adjusting guide rail 15 slides on the inner wall of the inclined guide rail 14, while the connecting guide rail 17 slides on the inner wall of the L-shaped guide rail 16. This changes the angle of the inclined guide rail 14 and the adjusting guide rail 15. After the angle of the inclined guide rail 14 and the adjusting guide rail 15 changes, the angle of the limiting rod 18 to move obliquely on the inclined guide rail 14 and the adjusting guide rail 15 will change, which in turn changes the angle of the cutting tool 11 to move obliquely. This allows for grinding of the conical surfaces of diamond composite cutting tools at different angles, thus making it suitable for diamond composite cutting tools of different specifications.

[0047] In this invention, when grinding and repairing diamond composite cutting teeth, the diamond composite cutting teeth are first inserted into the fixed cylinder 41, and then the electric push rod 42 is driven to extend, which drives the fixed plate 43 to move and clamp and fix the diamond composite cutting teeth.

[0048] Then, the servo motor 21 is started, driving the rotating shaft 20 to rotate, which in turn drives the driving wheel 23 to rotate, which in turn drives the driven wheel 24 to rotate, thereby driving the reciprocating screw 22 to rotate, causing the moving block 6 to slide on the inner wall of the groove 5, which in turn drives the grinding table 7 to move, and drives the tool holder 10 and the cutting tool 11 to move. At this time, the rotation of the rotating shaft 20 will synchronously drive the fixed cylinder 41 to rotate, thereby driving the fixed diamond composite cutting tooth to rotate. The horizontally moving cutting tool 11 contacts the surface of the rotating diamond composite cutting tooth and grinds it. The movement of the tool holder 10 will synchronously drive the limit rod 18 to move. The limit rod 18 will first move within the straight guide rail 12 (e.g., Figure 5 As shown), at this time, the blade 11 moves linearly, which can grind the cylindrical head of the diamond composite cutting tooth. Then, the limit rod 18 enters the inclined guide rail 14 and the adjusting guide rail 15, which will cause the tool holder 10 to swing to the right (as shown). Figure 5 As shown), at this time, the tool holder 10 will simultaneously drive the blade 11 to move diagonally to the right, and drive the two mounting shafts 8 to rotate clockwise (as shown). Figure 5 As shown), the blade 11 will travel along the conical surface of the diamond composite cutting tooth and grind its conical surface. Finally, when the limiting rod 18 moves into the connecting guide rail 17 and the L-shaped guide rail 16, the mounting shaft 8 will rotate and reset under the action of the torsion spring 44, thereby driving the blade 11 to reset and travel in a straight line again, thus grinding the cylindrical surface of the diamond composite cutting tooth. In this way, the entire travel trajectory of the blade 11 completely conforms to the special shape surface of the diamond composite cutting tooth, which can realize the rapid grinding and repair of the diamond composite cutting tooth.

[0049] When the cutting tool 11 reaches its end, it will move in the opposite direction to reset. When the cutting tool 11 is fully reset, the sector gear 31 will rotate to mesh with the first gear 30. At this time, the sector gear 31 will drive the first gear 30 to rotate, which in turn will drive the mounting rod 27 to rotate, which will drive the first bevel gear 28 to rotate, which will drive the second bevel gear 29 to rotate, which will drive the lead screw 25 to rotate, causing the slider 3 to slide in the slide groove 2, which will then drive the travel seat 4 to move, which will drive the grinding table 7 to move, which will then drive the cutting tool 11 to travel a unit distance towards the diamond composite cutting tooth, and then... The process involves secondary grinding, which is repeated until the surface damage of the diamond composite cutting tooth is repaired through grinding. The reason why the cutting tool 11 performs multiple grinding operations by intermittently traveling one unit distance is twofold: firstly, the width of the cutting tool 11 is fixed, and the grinding thickness of the diamond composite cutting tooth each time is limited, thus avoiding excessive overlap between the cutting tool 11 and the cross-section of the diamond composite cutting tooth in a single operation, which would cause excessive force on the surface of the cutting tool 11 during grinding and thus cause the cutting tool 11 to break; secondly, since the cutting tool 11 can move freely, it can grind diamond composite cutting teeth of different diameters, thus having a wider range of applications.

[0050] Furthermore, by using an external hex wrench to engage the nut 40, the adjusting rod 37 can be rotated, which in turn rotates the second gear 38, thereby rotating the third gear 39. This, in turn, causes the two rotating rods 13 to rotate synchronously, causing the inclined guide rail 14 and the adjusting guide rail 15 to rotate synchronously around the center of the rotating rod 13. This adjusts the angle of the inclined guide rail 14 and the adjusting guide rail 15. At this time, the adjusting guide rail 15 slides on the inner wall of the inclined guide rail 14, while the connecting guide rail 17 slides on the inner wall of the L-shaped guide rail 16. This changes the angle of the inclined guide rail 14 and the adjusting guide rail 15. After the angle of the inclined guide rail 14 and the adjusting guide rail 15 changes, the angle of the limiting rod 18 to move obliquely on the inclined guide rail 14 and the adjusting guide rail 15 will also change. This, in turn, changes the angle of the cutting tool 11 to move obliquely, thus enabling the grinding of the conical surfaces of diamond composite cutting teeth at different angles. Therefore, it can be used for diamond composite cutting teeth of different specifications.
