Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and more particularly to the field of ceramic blade grinding technology, specifically a multi-blade clamping grinding device. Background Technology

[0002] Ceramic blades are cutting tools made primarily of special ceramic powders such as alumina and silicon nitride, which are sintered under high temperature and pressure. The sintered blanks have many defects and must be ground to finish the cutting edge. For example, Chinese Patent CN218169688U discloses a ceramic blade sharpening device, including a sharpening machine body and a sharpening wheel disposed on one side of the sharpening machine body. The top of the sharpening machine body is provided with a positioning mechanism for positioning the ceramic blade, and the inner side of the sharpening machine body is provided with a drive mechanism for rotating the sharpening wheel. The positioning mechanism includes a limiting horizontal plate disposed on the top of the sharpening machine body and a movable frame disposed on the limiting horizontal plate. A limiting post is fixed in the middle of the limiting horizontal plate, passing through one end of the movable frame and rotatably connected to it. This avoids the cumbersome situation of sharpening both sides of the ceramic blade, making it more convenient to change to the other side of the ceramic blade for sharpening, improving the working efficiency of the ceramic blade sharpening device, and possessing strong practicality. It makes the sharpening of the ceramic blade more uniform, improves the sharpening effect of the ceramic blade sharpening device, and makes the sharpening process more flexible.

[0003] However, based on the actual processing and production use of existing grinding equipment, it still has certain drawbacks, such as: 1. Traditional grinding equipment lacks a synchronous linkage structure when processing multiple blades simultaneously. Multiple independent fixtures need to be operated and adjusted separately. The auxiliary operation of loading and unloading takes up a large proportion of time, resulting in a low effective grinding rate. At the same time, the clamping tightness and centering coaxiality of multiple blades cannot be kept consistent, resulting in large dispersion of blade edge size after grinding and poor product consistency.

[0004] 2. Ceramic cutting insert substrates are brittle. Existing fixtures use metal clamping blocks to directly and rigidly compress the inner ring of the insert. Stress concentration is easily generated during clamping, which can easily cause the insert to chip or break, significantly increasing the cost of scrapping the machining. In addition, the clamping block height of traditional fixtures is fixed, and the entire fixture needs to be replaced when changing inserts of different thicknesses, resulting in poor versatility.

[0005] 3. Existing equipment relies on manual addition or removal of metal shims to adjust the blade tilt angle. The shim positions are fixed, making it impossible to achieve continuous fine adjustment of the tilt angle. During batch processing, the blade grinding tilt angle is not uniform, resulting in grinding angle deviation.

[0006] 4. Ceramic grinding generates a large amount of hard, fine dust and sharp, flaky debris. The dust drifts freely into the workshop, which not only harms the respiratory health of operators, but also poses a safety hazard of scratching operators when the debris flies in. At the same time, the dust is very easy to adhere to the transmission gaps of motors, slide rails, and clamps.

[0007] Therefore, we propose a multi-blade clamping grinding device to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a multi-blade clamping grinding device to solve the problems mentioned in the background art, such as the lack of synchronous clamps, the fragility of rigid clamping tools, poor tilt angle adjustment accuracy, lack of dust collection, and the risk of injury to personnel and equipment.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a multi-plate clamping grinding device, comprising: a cabinet, a mounting table, a multi-station clamping mechanism, and a grinding mechanism. The mounting table is fixed to the top of the cabinet. The multi-station clamping mechanism is mounted on the left side of the mounting table and the grinding mechanism is mounted on the right side. The multi-station clamping mechanism includes a deflectable clamping table, a sealed housing, a synchronous internal support clamping assembly, and a worm gear linkage transmission pair. A rotary drive disk with an arc-shaped drive groove is provided inside the sealed housing. Multiple sets of clamping plate motion mechanisms are slidably arranged inside the rotary drive disk to achieve radial synchronous centering clamping. A worm wheel is coaxially fixed at the bottom of the rotary drive disk, and a worm is meshed with the outer side of the worm wheel to form a worm gear linkage transmission pair. The grinding mechanism includes a bottom loading frame and a top loading frame slidably connected to the right side of the mounting platform, and a grinding roller disposed inside the top loading frame. The bottom of the bottom loading frame is integrated with a negative pressure dust collection mechanism.

[0010] Furthermore: the sealing housing is composed of a bottom housing, a middle housing, and a top housing, which are bolted together from top to bottom. The bottom housing is fixed to the lower side of the clamping table by a flange. A cavity is formed between the middle housing and the top housing, and the rotary drive disk is rotatably installed in the cavity.

[0011] Furthermore: the clamping plate movement mechanism includes a U-shaped sliding seat, a transmission optical shaft, and a mounting vertical rod; the U-shaped sliding seat is slidably engaged with the internal sliding groove of the middle housing, the transmission optical shaft passes through the arc-shaped drive groove, the mounting vertical rod is slidably fitted with an inner support clamping block on its outer side, the upper and lower ends of the mounting vertical rod are respectively fitted with elastic buffers, and the top end of the mounting vertical rod is threaded with a locking nut.

[0012] Furthermore: a positioning support plate is fixed to the top side of the clamping table, and a threaded adjusting rod is rotatably mounted inside the positioning support plate. The front end of the threaded adjusting rod is connected to a positioning stop plate, and rotating the threaded adjusting rod can push the positioning stop plate to slide horizontally.

[0013] Furthermore: the end of the clamping platform is hinged to the inner side of the mounting platform, and two sets of first telescopic rods are symmetrically hinged to the bottom surface of the clamping platform, with the bottom end of the first telescopic rods hinged to the inner bottom surface of the mounting platform.

[0014] Furthermore: the right side of the mounting platform has a horizontally rotating translation adjustment screw and two parallel guide slide rods; the bottom of the bottom loading frame is respectively fixed with a screw drive seat and a sliding bushing; the screw drive seat is threadedly engaged with the translation adjustment screw; and the sliding bushing is slidably sleeved on the outside of the guide slide rods.

[0015] Furthermore: the bottom loading frame has vertically opened lifting grooves on both sides, and a lifting slider is slidably embedded in the lifting groove. The lifting slider is fixed to the side wall of the top loading frame, and a second telescopic rod is symmetrically arranged between the bottom loading frame and the top loading frame.

[0016] Furthermore: the negative pressure dust collection mechanism includes a waste collection plate, a waste discharge through hole, a waste discharge connecting pipe and a dust collection mechanism, which are inclinedly arranged inside the bottom loading rack; the waste collection plate is provided with a waste discharge through hole located on one side of the bottom loading rack at a low position, the waste discharge through hole is sealed and connected to the waste discharge connecting pipe, and the waste discharge connecting pipe extends downward into the cabinet and is connected to the dust collection mechanism.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: the multi-blade clamping grinding device can realize synchronous centering and clamping of multi-station blades, and the buffer clamping avoids the breakage of ceramic blades. It can continuously and uniformly adjust the grinding tilt angle, which is conducive to improving the working environment. At the same time, the grinding feed lifting adjustment is stable, which greatly improves the consistency, versatility and production efficiency of processing. 1. In this solution, a multi-station synchronous internal support clamping structure with worm gear linkage is used. A single worm gear can synchronously control the radial extension and retraction of all station clamping plates, and complete the centering and clamping of multiple cutting tools in one go. This greatly reduces the auxiliary time for loading and unloading. Moreover, the clamping tightness and centering coaxiality of each station are uniform. The self-locking of the worm gear can prevent the cutting tools from loosening and shifting during processing, effectively reducing the dimensional dispersion of the cutting edge after grinding and improving the consistency of batch product processing. 2. In this solution, the inner support clamping block is combined with upper and lower elastic buffers to disperse the clamping pressure and buffer the grinding vibration, preventing the brittle ceramic insert from chipping and breaking due to stress concentration. At the same time, the height of the clamping block can be freely adjusted by locking the nut, and the clamping stroke can be infinitely fine-tuned. It can adapt to ceramic inserts of different thicknesses and inner ring diameters without replacing the entire fixture. The three-section split sealed shell can also prevent dust from entering the clamping transmission structure, reduce jamming failures, and extend the service life of the fixture. 3. In this solution, the telescopic rod drives the stepless continuous deflection of the overall clamping table, which can precisely adjust the grinding angle of the blade. All blades deflect synchronously to ensure that the angle of the blades is uniform in batch processing. The positioning plate driven by the threaded adjustment rod locks the circumferential position of the blades, unifies the grinding direction of the cutting edge, and eliminates the manual calibration process for each blade. 4. This solution integrates a closed negative pressure dust collection mechanism. The inclined waste collection plate, together with the negative pressure airflow, completely encloses and collects dust and debris into the dust collection box inside the cabinet, preventing dust from spilling out. This not only protects the safety of operators but also isolates dust from precision components such as slide rails and motors, reducing equipment failures caused by dust wear and simplifying maintenance and operation. 5. In this solution, the grinding mechanism relies on a lead screw and double guide slides to achieve stable horizontal feed. The double-sided synchronous telescopic rods drive the grinding roller to rise and fall vertically, which can flexibly adjust the grinding position and pressing depth. The grinding depth of the cutting edge is uniform. The grinding, feeding, dust collection and tilt angle adjustment components are independently driven and controlled, which is suitable for rough grinding, fine grinding layer processing and automated batch production, further improving the overall processing efficiency.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figures 1-15 The present invention provides the following technical solution: A multi-plate clamping grinding device includes: a cabinet 1, a mounting table 2, a clamping table 3, a middle shell 4, a bottom shell 5, a clamping plate movement mechanism 6, a U-shaped sliding seat 601, a transmission optical shaft 602, a mounting vertical rod 603, a rotary drive disk 7, an arc-shaped drive groove 8, a top shell 9, a guide slide groove 10, an inner support clamping block 11, an elastic buffer 12, a locking nut 13, a worm gear 14, a worm 15, a positioning support plate 16, a positioning stop plate 17, a threaded adjustment rod 18, a first telescopic rod 19, a bottom loading frame 20, a top loading frame 21, a grinding roller 22, a translation adjustment screw 23, a screw transmission seat 24, a guide slide rod 25, a sliding bushing 26, a lifting slider 27, a lifting slide groove 28, a second telescopic rod 29, a waste chip collection plate 30, a chip discharge through hole 31, a chip discharge connecting pipe 32, and a dust collection mechanism 33. I. Overall machine foundation load-bearing structure The device includes a vertical hollow cabinet 1. A rectangular frame mounting platform 2 is fixed to the top end of the cabinet 1. The mounting platform 2 is divided into two independent working areas along its length. The left side of the mounting platform 2 is a ceramic blade clamping station, used to arrange blade clamping, positioning, and angle adjustment components. The right side of the mounting platform 2 is a grinding mechanism installation area, used to support the feeding, lifting, and driving of the grinding roller 22 and the entire grinding execution components. The cabinet 1 has a reserved layered cavity. The lower layer is a waste chip collection bin, and the upper layer is used to place the dust collection mechanism 33, wires and cables, hydraulic and pneumatic pipelines, motor drive controllers, and other electrical and fluid components.

[0022] In specific application scenarios: Cabinet 1 is used to accommodate the dust collection mechanism 33, store pipelines and electrical control components, and provide bottom support for all processing parts of the whole machine. The mounting table 2 serves as a unified installation benchmark for the blade clamping assembly and grinding feed assembly, dividing the processing area and realizing the partitioned arrangement of clamping and grinding processes.

[0023] The above technical solution is adopted: by using a layered and separate layout of cabinet 1 and mounting platform 2, the dust collection components and processing execution components are physically separated, avoiding grinding dust from contaminating the drive and control components and improving the service life of the equipment.

[0024] II. Single-station insert internal support clamping housing assembly Among them: multiple sets of circular through-holes are evenly spaced on the clamping platform 3. The single clamping mechanism shell structure consists of three cylindrical sections: bottom shell 5, middle shell 4, and top shell 9, which are coaxially assembled and fixed together by bolts from bottom to top. The outer edge of the bottom shell 5 extends into an annular flange, which is fixed to the lower plate of the clamping platform 3 by countersunk bolts to achieve axial positioning of the entire shell. The middle shell 4 passes vertically upward through the mounting hole of the clamping platform 3, and the upper cylindrical section protrudes completely from the upper surface of the clamping platform 3. The top shell 9 is coaxially bolted to the top end face of the middle shell 4. The inner wall of the middle shell 4 and the lower bottom surface of the top shell 9 enclose a sealed annular cavity.

[0025] In specific application scenarios: when multiple blades are processed simultaneously, an independent and enclosed mounting cavity is required to accommodate and hold the drive parts to prevent grinding debris from entering the transmission structure and causing jamming. The clamping mechanism can be arranged with different numbers of workstations, such as 4 or 6, according to production capacity requirements.

[0026] The above technical solution adopts a modular assembly of three-layer split shells: bottom shell 5, middle shell 4, and top shell 9. Each set of clamping mechanism can be independently disassembled and maintained. The closed cavity isolates external grinding dust, protects internal rotating and sliding transmission parts, and reduces equipment failure rate.

[0027] III. Clamping Plate Radial Telescopic Drive Mechanism The clamping plate is located inside the housing. The clamping plate movement mechanism 6 is integrally formed by a U-shaped sliding seat 601, a transmission optical shaft 602, and a mounting vertical rod 603. The U-shaped sliding seat 601 is slidably engaged in the matching groove inside the middle housing 4. The transmission optical shaft 602 is located between the middle housing 4 and the top housing 9. The mounting vertical rod 603 is a rod with external threads at the top and extends upward through the top housing 9. A rotary drive disk 7 is rotatably installed in the cavity between the middle housing 4 and the top housing 9. The rotary drive disk 7 has an arc-shaped drive groove 8, and the transmission optical shaft 602 is correspondingly inserted into the arc-shaped drive groove 8.

[0028] In specific application scenarios: the external transmission structure drives the rotary drive disk 7 to rotate clockwise around the central axis. The arc-shaped drive groove 8 squeezes the three transmission optical shafts 602 to slide radially outward in sync, driving the three sets of clamping plate motion mechanisms 6 to expand outward in sync along the T-shaped slide. When the rotary drive disk 7 rotates counterclockwise, the arc-shaped drive groove 8 pulls the transmission optical shafts 602 to contract in sync. By controlling the rotation angle of the rotary drive disk 7, the outward expansion stroke of the clamping plates can be continuously adjusted to adapt to ring blades with different inner ring diameters. The three sets of clamping plates move synchronously to automatically center the inner ring of the blade, ensuring that the blade has no eccentric offset.

[0029] The above technical solution is adopted: when the rotary drive disk 7 rotates, the arc-shaped drive groove 8 squeezes the transmission optical shaft 602, which drives the entire set of clamping plate motion mechanism 6 to slide radially synchronously, realizes stepless adjustment of clamping stroke, and automatically centers the inner ring of the ring blade to ensure the coaxiality of the blade after clamping, avoids the deviation of the cutting edge size caused by eccentric grinding, and is compatible with a full range of ceramic blades with different inner ring diameters.

[0030] IV. Blade Thickness Adaptation Buffer Clamping Assembly Specifically: Three through guide grooves 10 are radially opened on the upper end face of the top shell 9. The guide grooves 10 correspond one-to-one with the clamping plate movement mechanism 6. The rod section of the mounting rod 603 extending out of the top shell 9 is slidably fitted with a square block-shaped inner support clamping block 11. The inner support clamping block 11 can slide radially synchronously along the guide grooves 10, and can also slide vertically up and down along the mounting rod 603. Each mounting rod 603 has annular elastic buffers 12 fitted on its upper and lower end faces. The elastic buffers 12 can be rubber rings or springs. The threaded section at the top of the mounting rod 603 is threaded with a locking nut 13. The locking nut 13 presses against the upper elastic buffer 12 to lock the vertical height of the inner support clamping block 11.

[0031] In specific application scenarios, according to the axial thickness of the blade to be processed, the locking nut 13 is rotated to adjust the vertical height of the inner support clamping block 11 so that the clamping surface of the clamping block is aligned with the center of the inner ring thickness of the blade. The upper and lower elastic buffers 12 respectively fill the gaps between the inner support clamping block 11 and the transmission optical shaft 602, and between the inner support clamping block 11 and the locking nut 13. When the clamping plate expands outward to tighten the inner ring of the blade, the elastic buffer 12 absorbs the extrusion force of the metal hard contact, and the impact force generated by the grinding vibration can also be attenuated by the buffer pad to avoid the thin and brittle ceramic blade from chipping and breaking.

[0032] By adopting the above technical solution: tightening the locking nut 13 can adjust the vertical assembly height of the inner support clamping block 11 on the mounting rod 603, adapting to ceramic blades with different axial thicknesses. The upper and lower elastic buffers 12 isolate the metal hard contact, which can disperse the clamping and squeezing force, buffer the grinding vibration, eliminate the stress concentration caused by rigid clamping, effectively avoid the ceramic blade from being crushed by pressure and vibration, and improve the finished product processing qualification rate.

[0033] V. Multi-station synchronous linkage transmission components Among them: the worm gear 14 is coaxially connected to the lower end face of the rotary drive disk 7. The worm gear 14 is completely located below the bottom housing 5. The worm 15 is mounted through the inside of the clamping platform 3. The two ends of the worm 15 are rotated and supported by bearing seats. The tooth segments of the worm 15 are fully engaged with the tooth ring of the worm gear 14 to form a worm gear pair.

[0034] In specific application scenarios, multiple ceramic blades are placed on the outside of the clamping blocks of each set of clamping mechanisms. The operator turns the handwheel at the end of the worm gear 15 to drive the matching worm wheel 14 and the rotary drive disk 7 to rotate synchronously, completing the synchronous external support and centering of all workstation clamping plates in one go. After releasing the handwheel, the worm wheel and worm gear self-lock, and the clamping blocks remain in an expanded state to lock the blades. After processing is completed, the handwheel is turned in the opposite direction, and all clamping plates retract synchronously, so that all blades can be removed at once.

[0035] Using the above technical solution: the operation of a single worm gear 15 can synchronously link all the worm wheels 14 and rotary drive disk 7 of the workstations to rotate synchronously, and complete the synchronous centering and clamping of all the cutting tools on the table at one time, which greatly shortens the auxiliary time for loading and unloading multiple cutting tools. The worm gear transmission has reverse self-locking performance, and grinding vibration will not change the clamping expansion. The clamping state is stable and reliable, and there is no risk of cutting tool loosening or displacement throughout the entire processing. It is suitable for long-term continuous batch grinding production.

[0036] VI. Blade tilt angle adjustment base structure The clamping platform 3 is a long rectangular support plate. The ends of the clamping platform 3 are rotated and installed inside the mounting platform 2 via shafts. Two sets of first telescopic rods 19 are symmetrically hinged along the length of the bottom surface of the clamping platform 3. The top hinge seat of the first telescopic rod 19 is fixed to the lower surface of the clamping platform 3, and the bottom hinge seat is locked and fixed to the inner bottom surface of the mounting platform 2.

[0037] In specific application scenarios, based on the target cutting edge inclination angle of the ceramic blade to be processed, the two sets of first telescopic rods 19 are activated to extend or retract synchronously, causing the clamping table 3 to deflect upward or downward around the end shaft. The telescopic rods are locked after running to the target inclination angle.

[0038] The above technical solution is adopted: the two sets of first telescopic rods 19 extend and retract synchronously, which can drive the clamping table 3 to rotate smoothly and steplessly around the end shaft, ensuring that the overall tilt angle is completely uniform after multiple blades are clamped, adapting to the grinding of blades with various cutting edge tilt angles, and reducing product size deviation.

[0039] VII. Blade Circumferential Auxiliary Positioning Component Among them: an L-shaped positioning support plate 16 is fixed on the left edge of the top of the clamping table 3. A threaded adjustment rod 18 is rotatably installed inside the positioning support plate 16. The threaded adjustment rod 18 is connected to the back of the rectangular positioning abutment plate 17. The surface of the positioning abutment plate 17 is parallel to the back of the blade grinding side.

[0040] In specific application scenarios, before placing the blade, the rotating threaded adjustment rod 18 adjusts and moves the positioning plate 17, so that the positioning plate 17 moves to the non-grinding side positioning position of the blade for auxiliary positioning, which facilitates quick assembly of the blade.

[0041] The above technical solution is adopted: rotating the threaded adjustment rod 18 pushes the positioning plate 17 to slide horizontally. When clamping the blade, the non-grinding side of the blade is pressed against the positioning plate 17 to directly lock the circumferential rotational freedom of the blade, unify the orientation of all blade cutting edges, eliminate the need for repeated manual calibration and alignment, simplify the loading and unloading operation process, and ensure that the grinding position of each blade is completely consistent.

[0042] 8. Horizontal translation feed assembly of grinding mechanism Specifically: bearing seats are fixed at both ends of the middle of the grinding area on the right side of the mounting table 2. A horizontally rotating translation adjustment screw 23 is assembled between the bearing seats. One end of the translation adjustment screw 23 extends to the outside of the mounting table 2 and is connected to the output shaft of the feed drive motor through a synchronous transmission belt. Two guide slide rods 25 are symmetrically and parallelly arranged on both sides of the axis of the translation adjustment screw 23. Both ends of the guide slide rods 25 are also fixed on the bearing seats. The bottom loading frame 20 is a frame support for the grinding mechanism. A screw drive seat 24 is fixed at the center of the lower plate of the bottom loading frame 20. The screw drive seat 24 has a threaded hole inside and is threaded to engage with the translation adjustment screw 23. Sliding bushings 26 are symmetrically fixed on the left and right sides of the lower plate of the bottom loading frame 20. The sliding bushings 26 are coaxially and slidably sleeved on the outside of the guide slide rods 25.

[0043] In specific application scenarios, after the blade clamping, positioning, and angle adjustment are all completed, the feed drive motor is started. The motor drives the translation adjustment screw 23 to rotate in the forward direction through the transmission belt. The screw engages with the screw transmission seat 24, which drives the bottom loading frame 20 to feed smoothly towards the blade along the two guide slides 25.

[0044] The above technical solution is adopted: relying on the thread engagement to drive the lead screw transmission seat 24 and the bottom loading frame 20 to slide horizontally along the guide slide rod 25, which makes it easy to ensure that the grinding removal amount of all blades is uniform, the machining dimensions are consistent and excellent, and the machining efficiency is improved.

[0045] IX. Grinding depth adjustment component The bottom loading frame 20 has symmetrically vertically opening elongated lifting grooves 28 on both sides of the vertical plates. Lifting sliders 27 that can slide vertically are embedded inside the lifting grooves 28. The lifting sliders 27 on both sides are bolted to the left and right outer plates of the top loading frame 21 respectively. Two sets of second telescopic rods 29 are symmetrically connected between the bottom plate of the bottom loading frame 20 and the top plate of the top loading frame 21. The two sets of second telescopic rods 29 extend and retract synchronously to drive the top loading frame 21 to rise and fall vertically along the lifting grooves 28. A grinding roller 22 is horizontally rotated and assembled inside the top loading frame 21. The roller of the grinding roller 22 is covered with a wear-resistant diamond grinding layer. One end of the grinding roller 22 extends out of the outside of the top loading frame 21 and is independently connected to a grinding drive motor through a transmission belt. The grinding drive motor is fixed on the top surface of the top loading frame 21. The lifting action and the rotation drive of the grinding roller 22 are independent of each other.

[0046] In specific application scenarios, the grinding drive motor is started, which drives the grinding roller 22 to rotate continuously at a uniform speed. According to the processing procedure, the two sets of second telescopic rods 29 are controlled to retract synchronously, pulling the top loading frame 21 down along the lifting slide 28, and the grinding roller 22 presses down to contact the blade surface.

[0047] The above technical solution is adopted: the two sets of synchronously moving second telescopic rods 29 drive the top loading frame 21 to rise and fall smoothly and vertically along the lifting slide 28, and the depth of the grinding roller 22 pressed down to the blade surface can be freely adjusted to ensure that the height of the two ends of the grinding roller 22 is consistent after the lifting and lowering, the grinding depth of the entire blade edge is uniform, and the layered grinding process is highly adaptable.

[0048] 10. Waste and debris negative pressure centralized dust collection component Among them: the waste collection plate 30 is inclinedly welded and fixed on the inner bottom plate of the bottom loading frame 20. The waste collection plate 30 is a unidirectional inclined structure. A circular chip discharge through hole 31 is opened at the lowest position of the rear end of the bottom loading frame 20. The outer edge of the chip discharge through hole 31 is sealed and connected to a rigid chip discharge connecting pipe 32. The chip discharge connecting pipe 32 extends vertically downward into the inside of the cabinet 1. A dust collection mechanism 33 is installed in the lower collection compartment of the cabinet 1. The dust collection mechanism 33 includes a high-pressure negative pressure fan, a dust filter element, and a chip collection box. The air inlet of the fan is sealed and connected to the end of the chip discharge connecting pipe 32.

[0049] In specific application scenarios, the high-pressure fan inside the dust collection mechanism 33 is activated synchronously throughout the grinding operation. The fan continuously generates negative pressure, and the grinding debris and dust fall into the bottom loading rack 20. Relying on its own weight, it automatically slides along the inclined waste chip collection plate 30 to the lower chip discharge hole 31. The negative pressure airflow draws the debris and fine dust into the collection chamber inside the cabinet 1 along the chip discharge connecting pipe 32. After being filtered by the filter element, the clean air is discharged outward, and all solid grinding debris is retained in the chip collection box.

[0050] The above technical solution is adopted: solid grinding shavings are uniformly collected in the shavings collection box, and the entire collection path is fully enclosed with no overflow channels, so that there is no dust dispersion during grinding. This not only protects the workshop working environment, but also avoids grinding shavings splashing and damaging precision machining components. Dust cleaning only requires periodically pulling out the shavings collection box inside the cabinet 1, making maintenance simple and convenient.

[0051] Example:

[0052] When using this grinding device for multi-blade clamping grinding of ceramic inserts, refer to the following workflow: S1: After the equipment is turned on and inspected, rotate the threaded adjustment rod 18 to drive the positioning plate 17 to slide horizontally to the appropriate position, unify the circumferential limit reference of all workstation blades, loosen the locking nut 13 according to the axial thickness of the ceramic blade to be processed, adjust the vertical height of the inner support clamping block 11 along the installation vertical rod 603 so that the clamping surface is aligned with the center of the blade thickness, and complete the height locking of the clamping block with the upper and lower elastic buffers 12. S2: The multiple ring-shaped ceramic cutting tools are sequentially fitted onto the outer side of the inner support clamping block 11 of each station on the clamping table 3, so that the non-grinding side back of the cutting tool is in contact with the positioning plate 17, locking the circumferential rotational freedom of the cutting tool, and completing the initial alignment and placement of all cutting tools. S3: Rotate the handwheel at the end of the worm gear 15. The worm gear 15 engages and synchronously drives all the worm wheels 14 and rotary drive disk 7 to rotate in the same direction. The arc-shaped drive groove 8 on the rotary drive disk 7 squeezes the transmission optical shaft 602, which drives all the clamping plate motion mechanisms 6 to expand radially outward in sync. The inner support clamping block 11 supports the inner ring of the blade and automatically centers it. After releasing the handwheel, the worm gear and worm wheel self-lock, and the blade remains firmly clamped without eccentricity or deviation. S4: According to the cutting edge grinding angle required by the product, control the synchronous extension and retraction of the two sets of first telescopic rods 19, drive the overall clamping table 3 to smoothly deflect around the end shaft to the target angle and then lock it, ensuring that the processing angle of all cutting tools is completely uniform. S5: Start the feed drive motor. The motor drives the translation adjustment screw 23 to rotate. The screw meshes with the screw transmission seat 24, which drives the bottom loading frame 20 to slide horizontally along the two guide slide rods 25. The grinding roller 22 is moved as a whole to the top of the blade grinding station to complete the horizontal feed rough positioning. S6: Start the high-pressure negative pressure fan of the dust collection mechanism 33 inside the cabinet 1. The fan generates continuous negative pressure, and the chip discharge connection pipe 32 and the waste chip collection plate 30 form a closed negative pressure chip collection channel to collect grinding dust and debris synchronously throughout the process. S7: Turn on the grinding drive motor to drive the grinding roller 22 to rotate at a constant speed, control the two sets of second telescopic rods 29 to retract synchronously, pull the top loading frame 21 to slide smoothly down along the lifting slide 28, the grinding roller 22 presses down to contact the blade surface, adjust the pressing stroke according to the grinding allowance, and determine the single grinding depth. S8: The grinding roller 22 rotates continuously to grind the cutting edges of the multi-station blades simultaneously. The dust and grinding chips generated during grinding fall to the bottom of the loading rack and slide down to the chip discharge hole 31 by its own weight and negative pressure through the inclined chip collection plate 30. The chips are then drawn into the cabinet 1 for filtration and collection by the negative pressure airflow along the chip discharge connecting pipe 32. During the processing, the worm gear self-locking structure continuously maintains the blade clamping state without loosening or shifting. S9: After the grinding process is completed, control the second telescopic rod 29 to extend synchronously and push the top loading frame 21 to rise along the lifting slide 28 so that the grinding roller 22 is completely separated from the blade surface. If multi-layer grinding is required, repeat steps S6-S9 to adjust the feed and pressing depth until the blade cutting edge size meets the standard.
