Description

Technical Field

[0001] This invention relates to the field of cutting tool processing technology, and in particular to a feeding and conveying mechanism for diamond cutting tool production. Background Technology

[0002] Diamond cutting tools are highly efficient mining tools, with polycrystalline diamond composite sheets welded onto a cemented carbide matrix at their core. Their greatest advantage lies in their superior wear resistance and hardness, far surpassing traditional cemented carbide cutting tools. They are primarily used in mining equipment in coal mines, metal mines, and tunnel engineering, performing exceptionally well in breaking hard rock formations and under highly abrasive conditions. They significantly extend service life, reduce replacement frequency, improve rock-breaking efficiency, and substantially reduce downtime and overall costs, making them one of the representative advanced tools for efficient and economical hard rock mining.

[0003] Patent document CN118495089A discloses an alloy head feeding device for a cutting tooth production line, including a bracket. The bracket includes an alloy head feeding lifting mechanism, an anti-slip conveying mechanism, an electronic grabbing mechanism, and a rotary mechanism. The alloy head feeding lifting mechanism is located on one side of the bracket. One end of the alloy head feeding lifting mechanism is connected to the anti-slip conveying mechanism through an inclined receiving mechanism. The electronic grabbing mechanism is located above the anti-slip conveying mechanism. One end of the rotary mechanism is connected to an outlet of the anti-slip conveying mechanism, and the other end is connected to the top of the alloy head feeding lifting mechanism.

[0004] In existing technologies, gripping equipment is typically used to grip the diamond composite head and assemble it with the substrate.

[0021] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] like Figures 1 to 14 The illustrated feeding and conveying mechanism for diamond cutting tool production includes a base plate 1, and further includes: A limiting sleeve 2 is positioned above the base plate 1. A cutting tooth base 3 is located at the opening of the limiting sleeve 2, with one end of the cutting tooth base 3 inside the limiting sleeve 2. Figure 13 As shown, one end of the limiting sleeve 2 is fixedly connected with multiple limiting protrusions 4 along the circumferential direction, and multiple limiting grooves 5 are opened on the cutting tooth base 3 along the circumferential direction. The multiple limiting protrusions 4 are respectively located in the corresponding limiting grooves 5. A drive component is provided on the limiting sleeve 2. The drive component is used to drive the limiting sleeve 2 to reciprocate and rotate. A limiting component is provided on the base plate 1 and is used to limit the movement of the cutting tooth base 3. A rectangular base 6 is fixedly connected to the base plate 1, and a strip groove 7 is provided at the center of the rectangular base 6 (e.g., Figure 5 As shown), a sealing housing 8 is slidably connected inside the strip groove 7. A movable strip 9 is fixedly connected to the top of the sealing housing 8. The top of the movable strip 9 has multiple spherical grooves 10, and the bottom of the movable strip 9 has multiple connecting holes 11 (as shown). Figure 9As shown), multiple connecting holes 11 are connected to the corresponding spherical grooves 10 respectively. The top of the rectangular base 6 has two guide grooves 12 that slope downwards towards the strip groove 7. The top of the movable strip 9 slopes downwards from the center to both sides. A lifting assembly is mounted on a rectangular base 6 and is used to drive the movable bar 9 to move vertically. An adsorption component is disposed on the sealed housing 8 and is used to generate negative pressure in the sealed housing 8. One end of the cutting tooth base 3 is inserted into the limiting sleeve 2, and the limiting sleeve 2 is driven to move laterally by the driving component. During the movement, the limiting sleeve 2 is driven to rotate. Through the limiting component's limiting effect on the cutting tooth base 3 and the cooperation between the limiting protrusion 4 and the limiting groove 5, the cutting tooth base 3 moves and rotates synchronously. Multiple alloy balls are placed in each of the two guide slots 12. The movable bar 9 is driven to move into the strip groove 7 and is located below the two guide slots 12 by the action of the lifting component. After the alloy balls inside the two guide slots 12 are no longer blocked by the sealing shell 8 and the side of the movable bar 9, they converge on the top of the movable bar 9 along the inclined surface of the guide slot 12. At the same time, the negative pressure is generated in the sealing shell 8 under the action of the adsorption component, so that the negative pressure is generated at the connection between the connecting hole 11 and the spherical groove 10, causing the alloy balls to move into the corresponding spherical groove 10 and be adsorbed and positioned. When all the spherical grooves 10 are filled with alloy balls, the movable bar 9 is driven to move upward and return to the initial position by the action of the lifting component. During the upward movement of the movable bar 9, the alloy balls located at the top of the movable bar 9 and not in the spherical groove 10 roll to both sides through the inclined surface of the top of the movable bar 9 and fall back into the guide slot 12. After the movable bar 9 returns to the initial position, the adsorption component stops working. The drive assembly drives the cutting tooth base 3 to move past the top of the movable bar 9 and rotates during the lateral movement. During the rotation, the multiple inlay slots on the cutting tooth base 3 correspond sequentially with the alloy balls in the spherical grooves 10. The diameter of the inlay slots on the cutting tooth base 3 is slightly smaller than the diameter of the alloy balls. Thus, during the sequential correspondence between the inlay slots and the alloy balls, the alloy balls in the spherical grooves 10 can be interference-fitted into the corresponding inlay slots and disengaged from the corresponding spherical grooves 10, thereby completing the automatic assembly of the alloy balls. After the assembly is completed, the inlay of the alloy balls is permanently fixed by subsequent welding. In the process of feeding and transporting the cutting tooth base 3, the present invention enables the alloy balls to be automatically embedded during the movement of the cutting tooth base 3 by rotating the cutting tooth base 3 during displacement and filling and collecting the alloy balls by the spherical groove 10, thereby improving the embedding and assembly efficiency of the alloy balls.

[0023] As a further embodiment of the present invention, extrusion grooves 13 are provided on both sides of the strip groove 7 (e.g., Figure 9 As shown), the extrusion groove 13 is located below the guide groove 12. Each extrusion groove 13 is provided with an extrusion strip 14. Each side of the two extrusion strips 14 facing away from each other is fixedly connected to a U-shaped bracket 15. Both sides of the rectangular base 6 are provided with connecting grooves 16, which are connected to the corresponding extrusion grooves 13. Both ends of the U-shaped bracket 15 extend along the corresponding connecting grooves 16 to the outside of the rectangular base 6 and are fixedly connected with circular pins 17. Both sides of the rectangular base 6 are rotatably connected with rotating shafts 18. Cams 19 are fixedly connected to the rotating shafts 18. Both ends of the cams 19 are provided with convex grooves 20. One end of the circular pin 17 is located in the corresponding convex groove 20. Both sides of the rectangular base 6 are fixedly installed with first servo motors 21. The output shafts of the first servo motors 21 are fixedly connected to the corresponding rotating shafts 18. The movable bar 9 moves into the strip groove 7 and is located below the two extrusion grooves 13. The alloy balls inside the guide groove 12 converge at the top of the movable bar 9 along the inclined surface of the guide groove 12. The output shafts of the two first servo motors 21 rotate, driving the corresponding rotating shafts 18 to rotate, thereby causing the cam 19 to rotate synchronously. The circular pin 17 is guided and limited by the convex groove 20 on the cam 19, causing the U-shaped bracket 15 to move back and forth inside the connecting groove 16, and driving the extrusion bar 14 to move synchronously. This causes the adjacent ends of the two extrusion bars 14 to move from the inside of the corresponding extrusion groove 13 into the strip groove 7, and to push the alloy ball at the top of the movable bar 9 back and forth, thereby increasing the movement frequency of the alloy ball and improving the efficiency of the alloy ball entering the spherical groove 10.

[0024] As a further embodiment of the present invention, the lifting assembly includes: The first electric cylinder 22 is fixedly installed at the bottom of the rectangular base 6. The drive shaft of the first electric cylinder 22 extends into the interior of the strip groove 7 and is then fixedly connected to the bottom of the sealed housing 8. The transmission shaft of the first electric cylinder 22 moves downward, thereby driving the sealing housing 8 and the movable bar 9 to move downward synchronously. When the movable bar 9 is below the extrusion groove 13, the transmission shaft of the first electric cylinder 22 moves back and forth in a small amplitude, thereby causing the movable bar 9 to vibrate back and forth below the extrusion groove 13, and in conjunction with the reciprocating push of the extrusion bar 14, accelerating the efficiency of the alloy ball entering the spherical groove 10.

[0025] As a further embodiment of the present invention, the adsorption component includes: Vacuum pump 23 is fixedly installed at the bottom of the sealed housing 8, and the negative pressure end of vacuum pump 23 is fixedly connected to the sealed housing 8; The vacuum pump 23 operates to create a vacuum inside the sealed housing 8, and through multiple connecting holes 11, it creates an adsorption force at the corresponding spherical groove 10. When the alloy ball enters the spherical groove 10, the negative pressure adsorption effect generated at the connection between the connecting hole 11 and the spherical groove 10 adsorbs and fixes the alloy ball in the spherical groove 10.

[0026] As a further embodiment of the present invention, a pressure sensor 24 is fixedly installed on the vacuum pump 23; When the alloy ball enters the corresponding spherical groove 10, the connecting hole 11 and the spherical groove 10 come into contact with the alloy ball, reducing the number of negative pressure air intake positions, thereby causing a change in the air pressure detection value of the air pressure sensor 24. When all the spherical grooves 10 are filled with alloy balls, the air pressure detection value of the air pressure sensor 24 reaches its maximum value, thus ensuring that the filling of the alloy ball is completed. The controller connected to the air pressure sensor 24 controls the first electric cylinder 22 to work and drive the movable bar 9 back to the initial position.

[0027] As a further embodiment of the present invention, the driving component includes: A sliding bracket 25 is fixedly connected to the base plate 1. A slider 26 is slidably connected inside the sliding bracket 25. A lead screw 27 is rotatably connected inside the sliding bracket 25. The slider 26 is threadedly connected to the lead screw 27. A second servo motor 28 is fixedly installed on the sliding bracket 25. The output shaft of the second servo motor 28 is fixedly connected to one end of the lead screw 27. U-shaped frame 29 is fixedly connected to the bottom of slider 26. A connecting shaft 30 is rotatably connected inside U-shaped frame 29. One end of connecting shaft 30 passes through U-shaped frame 29 and is fixedly connected to the axis of limiting sleeve 2. Gear 31 is fixedly connected to connecting shaft 30. Rack 32 is fixedly connected to sliding bracket 25. Rack 32 and gear 31 mesh with each other. The output shaft of the second servo motor 28 drives the lead screw 27 to rotate, and the lead screw 27 is threadedly connected to the slider 26, causing the slider 26 to move along the sliding connection of the sliding bracket 25, and driving the U-shaped frame 29 to move synchronously. During the movement, the connecting shaft 30 inside the U-shaped frame 29 rotates in cooperation with the gear 31 and the rack 32, so that the limiting sleeve 2 rotates while moving laterally.

[0028] As a further embodiment of the present invention, the limiting component includes: A connecting bracket 33 is fixedly connected to the base plate 1. A fixed limiting strip 34 is fixedly connected to the top of the connecting bracket 33. Both ends of the fixed limiting strip 34 are provided with movable limiting strips 35. Multiple limiting pins 36 are fixedly connected to the bottom of each movable limiting strip 35. The limiting pins 36 are slidably inserted into the connecting bracket 33. A spring 37 is sleeved on each limiting pin 36. The spring 37 is fixedly connected between the connecting bracket 33 and the corresponding movable limiting strip 35. Both the fixed limiting strip 34 and the movable limiting strip 35 have a raised edge on one side. The top of the fixed limiting strip 34 and the movable limiting strip 35 supports the annular protrusion on the surface of the cutting tooth base 3, and the raised edge limits one end of the annular protrusion on the surface of the cutting tooth base 3, preventing the cutting tooth base 3 from detaching from the limiting sleeve 2. This ensures that the cutting tooth base 3 and the limiting sleeve 2 move synchronously. The cutting tooth base 3 is assembled with the alloy ball. The cutting tooth base 3 is located on the fixed limiting strip 34 to ensure stability during assembly. By pressing the movable limiting strips 35 on both sides, the movable limiting strips 35 drive the limiting pin 36 to move downward and compress the spring 37 to produce compression deformation, thereby causing the movable limiting strips 35 to move downward to make room, which facilitates the loading and unloading of the cutting tooth base 3.

[0029] As a further embodiment of the present invention, a mounting base 38 is fixedly connected to the base plate 1, and an arc-shaped groove 39 is formed on the top of the mounting base 38 (e.g., ...). Figure 11 As shown), a collection housing 40 is fixedly connected inside the arc-shaped groove 39. A circular through groove 41 is provided on the collection housing 40, and the circular through groove 41 is connected to the bottom surface inside the collection housing 40. A push rod 42 is provided at the end of the collection housing 40 away from the limiting sleeve 2. The push rod 42 is coaxially arranged with the circular through groove 41. A contact groove 43 is provided at the end of the push rod 42 near the circular through groove 41. A sliding frame 44 is slidably connected to the mounting base 38. The push rod 42 is fixedly connected to the sliding frame 44. A second electric cylinder 45 is fixedly installed on the mounting base 38. The drive shaft of the second electric cylinder 45 is fixedly connected to the sliding frame 44. Multiple diamond composite heads are placed inside the collection housing 40. The collection housing 40 limits the diamond composite heads to be stacked vertically. When the limiting sleeve 2 moves the cutting tooth base 3 to one side of the collection housing 40 and is coaxial with the circular through groove 41, the drive shaft of the second electric cylinder 45 drives the sliding frame 44 to move. The sliding frame 44 drives the push rod 42 to move into the circular through groove 41 and contact and fit with the convex surface of the diamond composite head through the contact groove 43. This pushes the bottom diamond composite head out of the collection housing 40 along the circular through groove 41 and presses it against the end of the cutting tooth base 3, thus completing the automatic assembly of the cutting tooth base 3 and the diamond composite head.

[0030] As a further embodiment of the present invention, such as Figure 11As shown, a laser emitter 46 is fixedly mounted on the mounting base 38, such as... Figure 3 As shown, a laser receiver 47 is fixedly installed on the U-shaped frame 29; When the U-shaped frame 29 moves the limiting sleeve 2 laterally, the laser receiver 47 moves synchronously with the U-shaped frame 29. When the limiting sleeve 2 is coaxial with the circular through groove 41, the laser emitter 46 and the laser receiver 47 are in a relative state. At the same time, the laser signal emitted by the laser emitter 46 is received by the laser receiver 47. The controller connected to the laser receiver 47 controls the second servo motor 28 to stop moving and controls the second electric cylinder 45 to work to assemble the cutting tooth base 3 and the diamond composite head. After the drive shaft of the second electric cylinder 45 completes a single reciprocating movement and returns to the initial position, the second servo motor 28 continues to work.

[0031] As a further embodiment of the present invention, a limiting ring 48 is fixedly connected to one end of the collecting shell 40 near the limiting sleeve 2. The inner side of the limiting ring 48 has the same inner diameter as the inner diameter of the circular through groove 41 and they are interconnected. When the limiting sleeve 2 is coaxial with the circular through groove 41, one end of the cutting tooth base 3 contacts the limiting ring 48, thereby limiting the movement of the diamond composite head through the limiting ring 48, ensuring that the diamond composite head can be accurately fitted at the end of the cutting tooth base 3.

[0032] Working principle of this invention: One end of the cutting tooth base 3 is inserted into the limiting sleeve 2, and the limiting sleeve 2 is driven to move laterally by the driving component. During the movement, the limiting sleeve 2 is driven to rotate. Through the limiting component's limiting effect on the cutting tooth base 3 and the cooperation between the limiting protrusion 4 and the limiting groove 5, the cutting tooth base 3 moves and rotates synchronously. Multiple alloy balls are placed in each of the two guide slots 12. The movable bar 9 is driven to move into the strip groove 7 and is located below the two guide slots 12 by the action of the lifting component. After the alloy balls inside the two guide slots 12 are no longer blocked by the sealing shell 8 and the side of the movable bar 9, they converge on the top of the movable bar 9 along the inclined surface of the guide slot 12. At the same time, the negative pressure is generated in the sealing shell 8 under the action of the adsorption component, so that the negative pressure is generated at the connection between the connecting hole 11 and the spherical groove 10, causing the alloy balls to move into the corresponding spherical groove 10 and be adsorbed and positioned. When all the spherical grooves 10 are filled with alloy balls, the movable bar 9 is driven to move upward and return to the initial position by the action of the lifting component. During the upward movement of the movable bar 9, the alloy balls located at the top of the movable bar 9 and not in the spherical groove 10 roll to both sides through the inclined surface of the top of the movable bar 9 and fall back into the guide slot 12. After the movable bar 9 returns to the initial position, the adsorption component stops working. The drive assembly drives the cutting tooth base 3 to move past the top of the movable bar 9 and rotates during the lateral movement. During the rotation, the multiple inlay slots on the cutting tooth base 3 correspond sequentially with the alloy balls in the spherical grooves 10. The diameter of the inlay slots on the cutting tooth base 3 is slightly smaller than the diameter of the alloy balls. Thus, during the sequential correspondence between the inlay slots and the alloy balls, the alloy balls in the spherical grooves 10 can be interference-fitted into the corresponding inlay slots and disengaged from the corresponding spherical grooves 10, thereby completing the automatic assembly of the alloy balls. After the assembly is completed, the inlay of the alloy balls is permanently fixed by subsequent welding. In the process of feeding and transporting the cutting tooth base 3, the present invention enables the alloy balls to be automatically embedded during the movement of the cutting tooth base 3 by rotating the cutting tooth base 3 during displacement and filling and collecting the alloy balls by the spherical groove 10, thereby improving the embedding and assembly efficiency of the alloy balls.
