Description

Technical Field

[0001] The present invention relates to the field of laser processing and manufacturing technology, in particular to a laser coordinated brazing CBN abrasive processing device and a processing method. Background Art

[0002] Brazed CBN abrasive processing equipment is a high-end device that integrates laser technology, brazing processes, and super-hard abrasive processing. Its core principle is to utilize the high energy density of lasers to rapidly melt the brazing material (such as a metal alloy) and form a high-strength metallurgical bond with the CBN (cubic boron nitride) abrasive and the substrate (such as a metal grinding wheel or tool base material). The result is a highly wear-resistant, high-cutting-efficiency abrasive tool or cutting tool for the precision machining of hard and brittle materials.

[0003] Existing CBN abrasive brazing equipment typically uses a traditional heating source combined with a mechanical clamping device to secure and braze the abrasive. The heat source melts the brazing material and wets the interface between the abrasive and the substrate, allowing the brazing material to flow naturally to form a bonded layer. While some systems incorporate lasers as a heating source, these only enable linear movement in a single direction, lack angle adjustment and electromagnetic control mechanisms, and often rely on a single mechanical clamp for abrasive fixation.

[0004] After the existing CBN abrasive brazing processing equipment melts, it is difficult to avoid excessive wrapping of the CBN abrasive due to differences in surface tension and wettability. This leads to insufficient exposure of the abrasive cutting edge, directly reducing the grinding efficiency of the abrasive tool. Local accumulation or uneven distribution is prone to occur, resulting in different bonding strengths of various parts of the abrasive tool, which in turn causes early shedding of the abrasive or cracking of the matrix, resulting in poor process adaptability.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. 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 making creative efforts are within the scope of protection of the present invention.

[0040] Please see the attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 The embodiment of the present invention provides a laser-assisted brazing CBN abrasive processing device and a processing method, comprising a base 2, a top shell 1 fixedly connected to the top of the base 2, a control panel 3 fixedly connected to the outside of the base 2, a base plate 9 fixedly connected to the top of the base 2, a grabbing assembly provided inside the top shell 1, a fixing assembly provided on the top of the base plate 9, a tensioning assembly and a spraying assembly provided on the top of the fixing assembly, a connecting block 44 provided inside the top shell 1 through a moving assembly, which is used to control the angle of the suppression assembly through an angle adjustment assembly to suppress excessive wetting of the brazing material on the CBN abrasive and suppress violent flow of the brazing material;

[0041] The fixing assembly includes a shell 19, which is fixedly connected to the top of the base plate 9. The inside of the shell 19 is rotatably connected to a fixing plate 23, the top of the fixing plate 23 is fixedly connected to a coil spring 22, and a clamping block 20 is placed outside the coil spring 22. The clamping block 20 is slidably connected to the top side of the middle part of the shell 19. The middle part of the shell 19 is fixedly connected to a motor three 16, the output end of the motor three 16 is fixedly connected to a worm one 17, and the middle part of the fixing plate 23 is fixedly connected to a worm gear one 18, which is engaged with the worm gear one 18. The tensioning assembly includes a bracket 21, which is fixedly connected to the top of the housing 19. A fixed disk 24 is fixedly connected to the top of the bracket 21. A gear three 27 is provided on the top of the fixed disk 24. A motor four 30 is fixedly connected to the middle of the fixed disk 24. The output end of the motor four 30 is fixedly connected to the gear two 26. The gear two 26 is engaged with the gear three 27. A movable block 25 is slidably connected to the middle of the fixed disk 24. A fixed rod 28 is fixedly connected to the top of the movable block 25. A slide groove 29 is provided in the middle of the gear three 27. The fixed rod 28 is slidably connected to the middle of the slide groove 29.

[0042] By starting motor 3 (16), worm 17 rotates. Since worm 17 meshes with worm gear 18 in the middle of fixed plate 23, the rotation of worm 17 drives fixed plate 23 to rotate within housing 19. As fixed plate 23 rotates, coil spring 22 attached to the top deforms, generating an elastic force. Clamping block 20 is slidably connected to the top side of the middle portion of housing 19. Driven by the elastic force of coil spring 22 and the thrust generated by the rotation of fixed plate 23, clamping block 20 slides toward the grinding tool, thereby clamping it from its outer edge. Motor 4 (30) in the middle of fixed plate 24 rotates gear 26. Gear 26 meshes with gear 3 (27), driving gear 3 to rotate at the top of fixed plate 24, driving movable block 25 to apply tension to the interior of grinding tools with internal circular holes, such as grinding wheels, saw blades, and grinding discs, securing them to housing 19. The tensioning assembly can be removed to secure grinding tools such as drills. The dual clamping mechanism of the fixed and tensioning components allows for adaptability to grinding tools of varying sizes, ensuring stable and reliable clamping. This prevents the grinding tool from shifting or loosening due to external forces, allowing the abrasive grains to maintain precise positioning during machining, ensuring machining accuracy and quality.

[0043] Please see the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 8The suppression assembly includes a laser light path 49, which is fixedly connected to the bottom of the connecting block 44. An electromagnetic coil 50 is provided on the outside of the laser light path 49. The moving assembly includes a motor 8, which is fixedly connected to the middle of the base plate 9. The output end of the motor 8 is fixedly connected to the screw 12. The outside of the screw 12 is provided with a side frame 6. The inside of the side frame 6 is fixedly connected to the cross frame 15. The outside of the cross frame 15 is slidably connected to the installation box 5. The middle of the installation box 5 is fixedly connected to the motor 2 13. The output end of the motor 2 13 is fixedly connected to the gear 14. The top of the cross frame 15 is provided with a rack 7. The gear 14 meshes with the rack 7. The bottom of the installation box 5 is fixedly connected to the cross plate 52. The adjustment assembly includes a motor 5 45 , which is fixedly connected to the bottom of the horizontal plate 52 , and the output end of the motor 5 45 is fixedly connected to the connecting frame 48 , and the internal rotation of the connecting frame 48 is connected to the worm gear 2 51 , and the bottom of the horizontal plate 52 is fixedly connected to the motor 6 47 , and the output end of the motor 6 47 is fixedly connected to the worm 2 46 , which is engaged with the worm gear 2 51 , and the connecting block 44 is fixedly connected to the bottom of the connecting frame 48 .

[0044] Motor 1 8 rotates screw 12, driving side frame 6 axially along the screw. Motor 2 13 meshes with rack 7 via gear 14, pushing mounting box 5 to slide horizontally on cross frame 15, thereby moving laser light path 49. Motor 5 45 and Motor 6 47 of the adjustment assembly respectively drive worm 2 46 to mesh with worm gear 2 51, rotating connecting frame 48 and adjusting the angle of laser light path 49 at the bottom of connecting block 44. Laser light path 49 provides localized heating to melt the brazing material, while an external electromagnetic coil 50 generates an alternating magnetic field, causing the brazing material and CBN abrasive grains to form a uniform bond layer on the grinding tool surface, improving brazing quality and process stability.

[0045] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 7 The grabbing assembly includes a mounting frame 32, the middle part of the mounting frame 32 is fixedly connected to the outside of the side frame 6, a motor 7 35 is provided in the middle part of the mounting frame 32, the output end of the motor 7 35 is fixedly connected to the screw 2 33, the outside of the screw 2 33 is provided with an electric push rod 1 31, the output end of the electric push rod 1 31 is fixedly connected to the fixing frame 38, the top of the fixing frame 38 is installed with a cylinder 34, the end of the cylinder 34 is fixedly connected to a disc 39, the bottom of the disc 39 is fixedly connected to a connecting rod 40, the outside of the connecting rod 40 is rotatably connected to a connecting rod 41, the outside of the connecting rod 41 is rotatably connected to a clamping claw 42, the bottom of the fixing frame 38 is fixedly connected to a connecting plate 37, the bottom of the connecting plate 37 is fixedly connected to a vertical rod 43, the clamping claw 42 is rotatably connected to the outside of the vertical rod 43, the connecting rod 40 is slidably connected to the middle part of the connecting plate 37, and a collection box 4 is placed on the top of the base 2.

[0046] By starting motor 7 35 to rotate screw 2 33, electric push rod 1 31 moves left and right along the axial direction of screw 2 33, thereby adjusting the position of the gripper. Electric push rod 1 31 ensures that the clamping jaws 42 can accurately reach the height of the grinding tool. Cylinder 34 pushes connecting rod 40 to slide along the middle of connecting plate 37. Connecting rod 41 drives clamping jaws 42 to rotate around vertical rod 43, achieving the opening and closing movement of clamping jaws 42. When clamping jaws 42 move to the appropriate position above the grinding tool, cylinder 34 pushes clamping jaws 42 to close. After grasping the grinding tool, screw 2 33 drives the grinding tool to move to collection box 4 for collection.

[0047] Please see the attached Figure 4 The spraying assembly includes a drive shaft 36, which is arranged on the top of the substrate 9. The outside of the drive shaft 36 is fixedly connected to a gear five 11. The middle of the shell 19 is rotatably connected to a gear four 10. The gear four 10 is engaged with the gear five 11. The top of the gear four 10 is fixedly connected to a support frame one 55 and a support frame two 56. A solder nozzle 53 is placed in the middle of the support frame one 55, and an abrasive nozzle 54 is placed in the middle of the support frame two 56.

[0048] The drive shaft 36 drives the gear 5 11 and the gear 4 10 to transmit, and drives the support frame 1 55 and the support frame 2 56 to rotate synchronously, so that the solder nozzle 53 and the abrasive nozzle 54 are sprayed as the support frame rotates. The dual nozzles spray solder and abrasive at the same time, thereby improving production efficiency.

[0049] Please see the attached Figure 9 As part of the present invention, an embodiment further provides a method for processing laser-assisted brazing CBN abrasive grains, comprising the following steps:

[0050] S1: applying force simultaneously from the inside and outside of the grinding tool through a tensioning assembly and a fixing assembly to fix the grinding tool;

[0051] Specifically:

[0052] The tensioning assembly slides outwardly against the inner side of the grinding tool to apply a first force;

[0053] The fixing assembly is tightened inwardly from the outside of the grinding tool to apply a second force.

[0054] S2: The brazing material and CBN abrasive are sprayed onto the fixed grinding tool substrate through the spraying assembly, and the laser light path is simultaneously started to melt the sprayed brazing material and weld the CBN abrasive to the substrate;

[0055] S3: adjusting the horizontal and vertical positions and the swing angle of the laser light path by adjusting components and moving components;

[0056] S4: After brazing is completed, the clamping of the grinding tool by the tensioning component and the fixing component is released, and the grinding tool is moved by the grabbing component.

[0057] Specifically include:

[0058] The internal and external forces applied to the grinding tool are released, and the brazed grinding tool is grabbed from the processing position by the clamping device and transferred to the collection box.

[0059] Working principle: The grinding tool to be processed is placed on the top of the shell 19, and the motor 4 30 drives the gear 2 26 and the gear 3 27 to rotate, so that the movable block 25 slides outward inside the fixed disk 24, and fixes and tensions it from the inside of the abrasive. The motor 3 16 drives the worm 17 to rotate, and drives the worm wheel 18 to rotate, so that the coil spring 22 rotates and drives the clamping block 20 to fix the outer edge of the grinding tool. The tensioning component and the fixing component are used to achieve double clamping of the grinding tool, which can fix processing equipment of different sizes; then the drive shaft 36 is started to drive the gear 5 11 to rotate. Since the gear 5 11 is engaged with the gear 4 10, the gear 5 11 drives the gear 4 10 to rotate, and then drives the solder nozzle 53 and the abrasive nozzle 54 to rotate, and sprays and smears the substrate and the grinding tool fixed on the top of the shell 19; while smearing, the laser light path 49 is used to melt the solder, so that the CBN abrasive is welded and fixed on the substrate or the grinding tool.

[0060] When the position of laser light path 49 needs to be adjusted, motor 18 drives screw 12 to rotate, causing side frame 6 to move back and forth on top of base plate 9. Gear 14 meshes with rack 7, driving motor 2 13 to move mounting box 5 laterally along horizontal frame 15, thereby adjusting the position of laser light path 49. Motor 5 45 and motor 6 47 respectively drive worm gear 2 51 and connecting frame 48 to swing, adjusting the angle between laser light path 49 and electromagnetic coil 50. This prevents excessive wetting of the CBN abrasive by the brazing material, suppresses the rapid flow of the brazing material, increases the exposed height and contouring of the CBN abrasive, and improves the machining accuracy of brazed CBN tools.

[0061] After the processing is completed, the cylinder 34 drives the connecting rod 41 to drive the clamping claw 42 to grab the grinding tool. At the same time, the slide groove 29 of the gear three 27 in the tensioning assembly slides with the fixed rod 28 to retract the force on the grinding tool, and the brazed grinding tool is moved from the top of the shell 19 to the inside of the collection box 4 for collection, realizing a fully automated process for fixing, positioning and processing the grinding tool. The transmission is through the rack 7 and gear 14, which shortens the processing cycle and improves the processing efficiency.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
