Description

Technical Field

[0001] This invention relates to the field of grinding wheel manufacturing technology, and in particular to a bonding device for CBN grinding wheel manufacturing. Background Technology

[0002] CBN grinding wheels use cubic boron nitride (CBN) as the abrasive, which is bonded into a specific shape and size using a binder (such as resin, metal, or ceramic). They are widely used in high-precision, high-efficiency grinding processes. The core component of CBN grinding wheels is cubic boron nitride, the second hardest synthetic material after diamond, second only to diamond in hardness, but with significantly superior thermal and chemical stability. CBN grinding wheels are manufactured by mixing CBN abrasive with a binder and then processing it through pressing, sintering, or curing. They possess high hardness, high wear resistance, high thermal stability, and good chemical inertness.

[0003] In existing technologies, before bonding CBN grinding wheels, fine particles such as dust, fibers, and metal shavings in the workshop air will naturally settle on the substrate surface. Waste residue will also remain during the substrate processing. Dust and other impurities will occupy the contact area between the adhesive and the substrate, forming a physical isolation layer. This prevents the adhesive from fully wetting the substrate surface, thereby reducing the bonding strength. Furthermore, it is difficult to quickly carry out bonding work after cleaning, resulting in low work efficiency. Therefore, a bonding device for CBN grinding wheel production is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the natural settling of dust, fibers, metal shavings, and other fine particles in the workshop air onto the substrate surface before bonding CBN grinding wheels, as well as the residual waste from substrate processing. Dust and other impurities occupy the contact area between the adhesive and the substrate, forming a physical isolation layer, which prevents the adhesive from fully wetting the substrate surface, thereby reducing the bonding strength. Furthermore, it is difficult to quickly perform bonding work after cleaning, resulting in low work efficiency. Therefore, this invention proposes a bonding device for CBN grinding wheel production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bonding device for CBN grinding wheel production includes a base, a linkage mechanism on top of the base, a drive motor on top of the base, a drive rod at the output end of the drive motor, a dust removal brush plate fixedly connected to the side of the drive rod away from the drive motor, a notched rack wheel fixedly connected to the side of the drive rod near the drive motor, a gear meshing with the side of the notched rack wheel, a connecting rod fixedly connected above the gear, a cross partition fixedly connected to the side of the connecting rod away from the gear, a base plate below the cross partition plate, and a bonding mechanism on top of the side of the base plate near the linkage mechanism. A bonding groove is provided on the side of the base near the bonding mechanism. A circular plate is fixedly connected to the side of the base near the cross partition. The cross partition divides the internal space of the circular plate into four parts. The drive motor drives the dust removal brush disc to rotate inside the base through the drive rod and cleans the bonding surface of the grinding wheel above. The drive rod drives the gear to rotate through the notched rack wheel. The notched rack wheel rotates one revolution and only drives the gear to rotate one-quarter of the revolution. The gear drives the cross partition to rotate one-quarter of the revolution through the connecting rod. When the cross partition rotates, it cooperates with the circular plate to rotate the dust-cleaned grinding wheel base to the top of the bonding groove. The bonding mechanism below the bonding groove is used to immediately bond the CBN film.

[0006] The above technical solution further includes: The equipment base is fixedly connected to the drive motor, the connecting rod is rotatably connected to the base, and the connecting rod is rotatably connected to the equipment base.

[0007] The notched rack and pinion drive the gear to rotate a quarter circle before disengaging from the gear, thus creating intermittent motion.

[0008] The bonding mechanism includes a hydraulic rod mounted above the equipment base, and a movable plate is mounted on the output end of the hydraulic rod.

[0009] The equipment base is fixedly connected to the drive motor, and a sliding groove is provided above the moving plate, with an L-shaped positioning plate slidably connected above the sliding groove.

[0010] The slide groove and L-shaped positioning plate are provided in multiple sets to ensure the stability of the CBN film before bonding.

[0011] A limiting plate is slidably provided on the side of the base near the bonding groove, and a pull rod is fixedly connected below the limiting plate.

[0012] The device is equipped with multiple sets of tie rods and limiting plates, which ensures that it is suitable for bonding grinding wheels of different sizes.

[0013] The base has a dust removal groove on the side near the dust removal brush disc, and the dust removal brush disc is located inside the dust removal groove.

[0014] A cover plate is rotatably connected to the side of the annular plate, and a handle is fixedly connected to the side of the cover plate.

[0015] An elastic pressure plate is provided above the handle.

[0016] A support column is fixedly connected above the side of the equipment base away from the drive motor, and the support column is fixedly connected to the base.

[0017] The present invention has the following beneficial effects: 9. In this invention, the motor drives the dust removal brush disc to rotate at high speed via the drive rod, thoroughly cleaning the bonding surface of the grinding wheel substrate, removing impurities such as dust, fibers, and metal shavings, preventing the formation of a physical isolation layer, and ensuring that the adhesive fully wets the substrate surface. The special meshing design of the notched rack wheel and gear (one rotation only drives the gear to rotate 1 / 4 of a circle) realizes the intermittent quarter-circle rotation of the cross plate, precisely controlling the positioning and transfer of the grinding wheel substrate. After dust removal, the grinding wheel substrate is transferred to the top of the bonding groove, and the hydraulic rod drives the moving plate to rise, which, together with the L-shaped positioning plate, fixes the CBN base plate, achieving rapid bonding, avoiding secondary pollution, avoiding the time loss of waiting for bonding after cleaning, and significantly improving work efficiency.

[0018] 10. In this invention, the cross partition divides the internal space of the ring plate into four parts, forming four independent workstations, which can simultaneously place multiple grinding wheel substrates. Driven by the linkage mechanism, each workstation sequentially completes the dust removal, conveying and bonding steps, realizing batch continuous production and further improving production efficiency.

[0019] 11. In this invention, the hydraulic rod drives the moving plate to precisely press down in the bonding mechanism, ensuring full contact between the CBN substrate and the grinding wheel base. The sliding groove and L-shaped positioning plate on the moving plate can accommodate CBN substrates of different sizes, achieving stable fixation. Simultaneously, the limiting plate and pull rod design on the base can be adjusted to fix grinding wheel bases of different sizes. Combined with the coaxial design of the bonding groove and bonding mechanism, this ensures the accuracy and non-offset nature of the bonding. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-7As shown, this invention is a bonding device for CBN grinding wheel production, including a base 1. A linkage mechanism is arranged above the base 1. The linkage mechanism includes a drive motor 2 arranged above the base 1, a drive rod 3 arranged at the output end of the drive motor 2, a dust removal brush disc 4 fixedly connected to the side of the drive rod 3 away from the drive motor 2, a notched rack wheel 5 fixedly connected to the side of the drive rod 3 near the drive motor 2, a gear 6 meshing with the side of the notched rack wheel 5, a connecting rod 7 fixedly connected above the gear 6, a cross partition 8 fixedly connected to the side of the connecting rod 7 away from the gear 6, a base 9 arranged below the cross partition 8, and a bonding mechanism arranged above the side of the base 1 near the linkage mechanism. A bonding groove 10 is provided on one side of the bonding mechanism. A circular ring plate 11 is fixedly connected to the side of the base 9 near the cross partition 8. The cross partition 8 divides the internal space of the circular ring plate 11 into four parts. The drive motor 2 drives the dust removal brush disc 4 to rotate inside the base 9 through the drive rod 3 and cleans the bonding surface of the upper grinding wheel. The drive rod 3 drives the gear 6 to rotate through the notched rack wheel 5. The notched rack wheel 5 rotates once and only drives the gear 6 to rotate one-quarter of the circumference. The gear 6 drives the cross partition 8 to rotate one-quarter of the circumference through the connecting rod 7. When the cross partition 8 rotates, it cooperates with the circular ring plate 11 to rotate the dust-cleaned grinding wheel base to the top of the bonding groove 10. The bonding mechanism below the bonding groove 10 is used to immediately bond the CBN film.

[0024] The equipment base 1 is fixedly connected to the drive motor 2, the connecting rod 7 is rotatably connected to the base 9, and the connecting rod 7 is rotatably connected to the equipment base 1.

[0025] In this embodiment, the grinding wheel substrate is placed into the four-part space formed between the cross partition 8 and the annular plate 11. The linkage mechanism above the equipment base 1 is activated, and the drive motor 2, which is fixedly installed above the equipment base 1, starts running. When the drive motor 2 runs, it controls the drive rod 3 at its output end to rotate. When the drive rod 3 rotates, it drives the dust removal brush disc 4, which is fixedly connected to its other side, to rotate. When the dust removal brush disc 4 rotates, it removes dust from the bonding surface of the grinding wheel substrate placed above. At the same time, after the drive rod 3 completes one rotation of dust removal, the drive rod 3 synchronously drives the notched rack wheel 5 to rotate. At this time, the notched rack wheel 5 has rotated to form a meshing connection with the gear 6. The notched rack wheel 5 will then drive the gear 6 to rotate a quarter circle. After rotation, the gear 6 disengages from the gear 6. When the gear 6 rotates, it drives the connecting rod 7 to rotate between the equipment base 1 and the base 9. The connecting rod 7 passes through the interior of the base 9 to drive the cross partition 8 to rotate. The cross partition 8 rotates one-quarter of the way and moves the dust-removed grinding wheel substrate one-quarter of the way around. The grinding wheel substrate moves to the top of the bonding groove 10 opened inside the base 9. At this time, the bonding mechanism set on the top of the equipment base 1 is activated. The bonding mechanism is used to bond the CBN substrate to the bottom of the grinding wheel substrate. The cross partition 8 and the ring plate 11 are separated into multiple spaces, so that the device can bond multiple grinding wheel substrates at one time. The intermittent motion formed in the linkage mechanism not only ensures that there are no impurities affecting the bonding process, but also improves the bonding efficiency.

[0026] In one embodiment, the bonding mechanism includes a hydraulic rod 12 disposed above the equipment base 1, and a movable plate 13 is disposed at the output end of the hydraulic rod 12.

[0027] The equipment base 1 is fixedly connected to the drive motor 2. A sliding groove 14 is provided above the moving plate 13, and an L-shaped positioning plate 15 is slidably connected above the sliding groove 14.

[0028] In this embodiment, the bonding mechanism includes a hydraulic rod 12 fixedly connected above the equipment base 1. The hydraulic rod 12 can extend and retract by controlling its output end, which can drive the moving plate 13 set at its output end to move up and down. The hydraulic rod 12 drives the moving plate 13 to move into the bonding groove 10 above, until the CBN substrate is bonded to the bottom of the grinding wheel substrate. Multiple sets of sliding grooves 14 are evenly opened in a circular pattern above the moving plate 13. An L-shaped positioning plate 15 is slidably arranged above each set of sliding grooves 14. Multiple sets of L-shaped positioning plates 15 can fix CBN substrates of different sizes.

[0029] In one embodiment, for the base 9, a limiting plate 17 is slidably provided on the side of the base 9 near the adhesive groove 10, and a pull rod 16 is fixedly connected below the limiting plate 17.

[0030] In this embodiment, a limiting plate 17 is slidably provided on the side of the base 9 near the bonding groove 10. Multiple sets of limiting plates 17 are provided. Each set of limiting plates 17 can be slidably adjusted by the pull rod 16 fixedly connected below each set of limiting plates 17, so as to fix grinding wheel bases of different sizes. The central axis of the bonding groove 10 is aligned with the circular axis of the bonding mechanism to ensure that the bonding is not offset.

[0031] In one embodiment, for the base 9, a dust removal groove 18 is provided on the side of the base 9 near the dust removal brush disk 4, and the dust removal brush disk 4 is disposed inside the dust removal groove 18.

[0032] In this embodiment, when the dust removal brush disk 4 rotates, the dust removal brush disk 4 will rotate on the inner wall of the dust removal groove 18 opened inside the base 9.

[0033] In one embodiment, for the aforementioned annular plate 11, a cover plate 19 is rotatably connected to the side of the annular plate 11, and a handle 20 is fixedly connected to the side of the cover plate 19.

[0034] An elastic pressure plate 21 is provided above the handle 20.

[0035] In this embodiment, a cover plate 19 is rotatably connected to the side of the annular plate 11. The cover plate 19 can be opened and closed by a handle 20 fixedly connected between its sides. An elastic pressure plate 21 is provided above the handle 20. The elastic pressure plate 21 is made of a soft and elastic material, which will not cause pressure damage to the grinding wheel. It can keep the bonding process sealed during the operation of the device to prevent external factors from affecting the bonding process.

[0036] In one embodiment, for the device base 1, a support column 22 is fixedly connected above the side of the device base 1 away from the drive motor 2, and the support column 22 is fixedly connected to the base 9.

[0037] In this embodiment, multiple sets of support columns 22 are fixedly connected between the equipment base 1 and the base 9, and the multiple sets of support columns 22 fix the equipment base 1 and the base 9 into a whole.
