Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a quick-change mounting mechanism for an integrated cutting blade wheel. Background Technology

[0002] In cutting machine tools using integrated cutting wheels, the cutting wheel assembly consists of a tool holder and a cutting wheel at its end, integrally formed. The tool holder is inserted into the mounting hole of the headstock tool holder by a plug-in method, and axial positioning and circumferential torque transmission are achieved through a locking mechanism. Although the integrated configuration eliminates the accumulated tolerances caused by the split assembly, under actual cutting conditions, high-frequency impact loads and alternating tangential torques make it easy for high-hardness and highly abrasive cutting dust to penetrate into the mating interface between the outer circle of the tool holder and the inner hole of the tool holder. Under continuous vibration excitation, progressive abrasive wear occurs on the mating surface between the tool holder and the tool holder, leading to a deterioration of the mating condition between the tool holder and the tool holder, a significant decrease in the locking preload, and consequently, radial wobble and angular deflection of the cutting wheel. Because the cutting process places stringent requirements on the radial centering accuracy and torsional stiffness of the cutting wheel, once the effective clamping force of the locking mechanism decreases due to dust abrasion, the cutting wheel will generate a significant torsional offset under the action of tangential torque, ultimately forming uneven cut marks or edge chipping on the workpiece cutting surface, severely degrading the processing quality.

[0003] To address the aforementioned issues, existing technologies offer several solutions. For example, one approach uses radial bolts to directly clamp the tool holder, requiring external tools to tighten the bolts for clamping and releasing during tool changes. While this method is structurally simple, on-site tool changing is cumbersome, necessitating repeated torque adjustments, extending equipment downtime, and reducing production line efficiency. Another approach involves introducing quick-release spring-loaded locking mechanisms, attempting to achieve rapid manual tool changes using the instantaneous reset action of the elastic element. However, to ensure smooth insertion and removal of the tool holder, such mechanisms necessitate a necessary assembly gap between the tool holder and the tool holder. This gap directly degrades initial centering accuracy. Furthermore, the elastic element, constantly exposed to high-load cutting forces and abrasive dust, is prone to fatigue relaxation, jamming, and even breakage, failing to meet the engineering requirements of high-precision cutting for torsional rigidity and consistent repeatability.

[0004] Therefore, there is an urgent need to develop a quick-change mounting mechanism for integrated cutting wheel. This mechanism should effectively resist wear on mating surfaces and decline in locking force caused by dust intrusion, while ensuring high-precision centering and high-rigidity anti-rotation performance. It should also enable tool-free and rapid locking and releasing operations to meet the requirements of high-efficiency and high-precision continuous production of high-quality workpieces. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-change mounting mechanism for an integrated cutting wheel, so as to solve the problem mentioned in the background art that the existing mounting mechanisms cannot simultaneously achieve the convenience of quick-change operation, installation accuracy, and locking reliability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A quick-change mounting mechanism for an integrated cutting wheel includes a tool holder and a cutting wheel assembly. The tool holder has a locating inner hole that extends axially from top to bottom. The lower part of the locating inner hole is configured as a truncated pyramidal conical female hole. A dovetail-shaped guide groove is formed axially on one side wall of the conical female hole. The cutting wheel assembly includes a tool bar and a cutting wheel located at the bottom end of the tool bar. The top end of the tool bar is a male cone that matches the conical female hole. One side of the male cone has a sliding block that matches the guide groove. The other side of the male cone opposite the sliding block... An arc-shaped locking groove is provided on one side, and the top of the locking groove is provided with an inwardly downward inclined pressure surface; the tool holder is also provided with an eccentric locking assembly, which includes a camshaft and an operating handle. The camshaft is horizontally arranged and rotatably connected to the tool holder. One end of the camshaft extends to the outside of the tool holder and is fixedly connected to the operating handle. The middle section of the camshaft is provided with an outwardly convex eccentric driving arc surface. The operating handle is used to drive the camshaft to rotate so that the eccentric driving arc surface cuts into the locking groove and presses against the pressure surface.

[0007] By setting a frustum-shaped conical female hole and a dovetail-shaped guide groove in the tool holder, and setting the top of the tool bar as a matching male cone and slider, the slider slides axially along the guide groove during the assembly of the tool wheel assembly, so that the male cone and the conical female hole can achieve a large-area surface contact fit. Relying on the multi-faceted constraint of the frustum shape and the axial wedging effect of the conical surface, not only can the circumferential coarse positioning of the tool wheel assembly be achieved before external force locking, but also the radial assembly gap of the mating interface can be forcibly eliminated, ensuring the initial coaxiality of the tool wheel assembly in the tool holder, realizing high-precision radial centering, thereby ensuring the straightness and depth uniformity of the glass cutting marks.

[0008] Furthermore, by setting an eccentric locking assembly including a horizontal camshaft and an operating handle, the camshaft is driven to rotate by the operating handle, causing its convex eccentric driving arc surface to cut into the arc-shaped locking groove on the side of the male cone and press against the inwardly downward inclined pressure surface. Under the combined action of the eccentricity and the inclined surface, the unidirectional rotational torque can be converted into a bidirectional rigid component force in the axial upward and lateral radial directions. The axial component force presses the male cone deeply into the conical female hole to achieve rigid locking, while the radial component force causes the slider part to fit tightly against the inclined surface of the guide groove, forming a high-rigidity composite anti-rotation closed loop in the tangential direction. This effectively prevents the slight deflection of the cutter wheel caused by high-frequency axial impact and tangential torque fluctuation during glass cutting, avoiding uneven cutting lines or chipping on the glass surface and ensuring the processing quality of the glass.

[0009] Furthermore, the integrated cutting wheel can be instantly locked and released by rotating the handle, shortening the downtime for tool replacement and maintenance on site. At the same time, the tight contact between the conical mating surfaces in the locked state constitutes a hard seal interface, preventing the intrusion of high-hardness, highly abrasive glass dust from the source. This eliminates the defects of gaps and locking force attenuation caused by dust abrasion in the locking pair, reducing the wear rate of the mechanism. Even under long-cycle, continuous, and heavy production conditions, it has extremely high structural stability and an ultra-long service life.

[0010] Preferably, the tool holder is provided with a limiting block, and the eccentric driving arc surface is configured to rotate to a dead-point state beyond the maximum eccentricity point under the drive of the operating handle, and when the eccentric driving arc surface is in the dead-point state, the operating handle and the limiting block abut against each other.

[0011] By providing a limiting stop on the tool holder, when the integrated cutting wheel is locked, the driving handle drives the camshaft to rotate in the locking direction, causing the eccentric drive arc surface to cut into the locking groove and pass the maximum eccentricity point. During the process, the locking resistance generated by the eccentric drive arc surface first increases and then decreases until the operating handle and the limiting stop make hard contact. At this time, the entire eccentric locking assembly crosses the dead point and is limited, which not only provides the operator with clear physical feedback on locking and positioning, but also transforms the high-frequency axial impact force and tangential torque generated by glass cutting into a tendency force that makes the operating handle further press against the limiting stop. This effectively prevents the camshaft from reversing and unlocking under severe vibration conditions, and further ensures the locking reliability of the mating surface between the tool holder and the cutting wheel assembly.

[0012] Furthermore, when the operating handle is rotated in the reverse direction to release and replace the cutter wheel assembly, the limit stop restricts the starting point of the locking stroke, preventing over-travel interference of the internal components of the eccentric locking assembly caused by blind operation or excessive reverse rotation of the operating handle, thus ensuring the accuracy of the quick-change release action. At the same time, when the machine head is carrying the cutting cutter wheel for continuous high-speed cutting operations, the limit stop provides a rigid lateral positioning support surface for the operating handle in the locked state, restricting the circumferential degree of freedom of the operating handle, and preventing mechanical resonance caused by the inertia of its own mass during follow-up reversal or high-speed reciprocating motion, thereby ensuring the mechanical stability of the overall mechanism in high-frequency glass cutting operations.

[0013] Preferably, a mounting groove is formed on the large end face of the conical female hole, and a dust scraper ring protruding inward is fixedly disposed in the mounting groove. The inner contour of the dust scraper ring is adapted to the outer peripheral surface of the male cone, and slides in an interference fit with the outer peripheral surface of the male cone during axial insertion.

[0014] By creating an installation groove on the large end face of the conical female hole and fixing a dust scraper ring thereon, when the cutter wheel assembly is axially inserted, the male cone moves inward along the axial direction, causing the dust scraper ring to slide and wipe against the outer circumferential surface of the male cone. This provides a clean surface free of fine particulate matter contamination for the mating interface that is about to be joined, thereby preventing high-hardness glass dust generated during the plate cutting process from being trapped between the two conical surfaces during locking. This effectively prevents the mating surfaces from being ground or accumulating tolerances under severe vibration, further ensuring the cleanliness of the original contact state of the internal positioning mating surfaces.

[0015] Furthermore, when the cutter wheel assembly is fully inserted and locked into the conical female hole, the dust scraper ring, under interference deformation, tightens around the outer circumference of the root of the male cone. As the male cone continues to penetrate deeper, the dust scraper ring will tightly adhere to the surface of the male cone, forming a fully enclosed physical chip-breaking and sealing barrier until the cutter wheel assembly reaches the mechanical positioning dead point. At this time, the dust scraper ring maintains a tight sealing state under the constraint of its own interference elasticity, ensuring that continuous glass dust splashed from the outside during operation cannot seep back into the positioning inner hole from the root gap, thus avoiding secondary contamination of the internal eccentric locking component by dust. At the same time, the inner contour of the dust scraper ring is interference-fitted with the male cone throughout the entire insertion and extraction process, ensuring the axial stability of the cutter wheel assembly during insertion and descent, and preventing lateral displacement or eccentric wobbling of the cutter wheel assembly due to uneven insertion and extraction force during manual quick-change operation, thereby ensuring the stability of the cutter wheel assembly during loading, unloading, changing, and moving operations.

[0016] Preferably, the upper section of the positioning inner hole is provided with a cooling channel, and the top center of the tool bar is provided with an exhaust channel that is coaxial with and connected to the cooling channel. The exhaust channel passes through the tool bar axially downward and leads directly to the tool wheel at the lower end.

[0017] By setting a cooling channel in the upper section of the positioning inner hole and an exhaust channel coaxially connected to and passing through the cutter bar and leading directly to the cutter wheel at the top center of the cutter bar, high-pressure cooling airflow can be smoothly injected from the upper section of the cutter holder during high-intensity glass cutting operations. This airflow is then transported axially to the bottom cutting point, directly and efficiently cooling the interface between the cutter wheel and the glass. This effectively suppresses thermal wear of the cutter wheel and edge chipping of the glass due to intense friction and heat generation. Simultaneously, the high-pressure airflow ejected at high speed from the bottom of the exhaust channel forms a powerful local positive pressure purging zone around the cutter wheel. This forcefully peels away and removes glass dust instantly upon its generation, cutting off the physical path of high-hardness dust drifting upwards and intruding into the locking interface, ensuring the cleanliness of the entire mechanism for long-term operation.

[0018] Furthermore, by configuring the cooling channel and the exhaust channel as a coaxial line, the two-section fluid transmission path can achieve automatic, precise, and seamless coaxial docking during the axial insertion and eccentric locking of the tool holder, relying entirely on mechanical positioning references. This eliminates the need for additional external pipelines or manual connectors, greatly simplifying the quick-change operation and improving overall efficiency. Simultaneously, the axially central through-hole channel design reuses the non-primary load-bearing core area inside the tool holder, ensuring minimal flow resistance and low pressure loss during airflow transmission. It also avoids weakening the overall cross-sectional moment of inertia of the tool holder due to opening pipelines on the outer circumference, preserving the torsional stiffness and axial impact stiffness of the tool holder. This ensures the structural stability and machining accuracy of the tool wheel assembly under high-frequency vibration operation.

[0019] Preferably, the eccentric locking assembly further includes a torsion spring sleeved on the camshaft, the torsion spring being used to provide an initial preload force for the operating handle and the camshaft to rotate toward the locking termination position.

[0020] By installing a torsion spring on the camshaft and applying a continuous initial preload towards the locking termination position to the operating handle and the camshaft during the locking operation, the camshaft, under the action of elastic energy storage, tends to actively rotate and cut into the locking groove after the cutter wheel assembly is inserted into place. When the operating handle is driven to cross the dead point position of the maximum eccentricity point, the torsion spring can release torque instantaneously, assisting the operating handle to accelerate past the dead point and forcefully engage to the termination state of abutting against the limit stop. This eliminates the safety hazard of the eccentric mechanism failing to fully enter the dead point locking due to insufficient manual operation force or improper operation, thereby ensuring the thoroughness of the initial locking state and the consistency of assembly accuracy.

[0021] Furthermore, during continuous, high-frequency vibration cutting operations, the continuous forward elastic preload provided by the torsion spring and the over-dead-point self-locking mechanism form a double anti-vibration defense, pressing the operating handle onto the limit block. This prevents the camshaft from vibrating away from the over-dead-point position due to reverse impact or resonance caused by the high-frequency cutting load of the glass, ensuring locking stiffness under long-cycle continuous operation. At the same time, when releasing and unlocking the operating handle by rotating it in the opposite direction, the operator must actively overcome the torsional resistance of the torsion spring. This gives the operating handle clear anti-disturbance mechanical damping, effectively preventing the operating handle from accidentally swinging or mis-locking due to its own mass inertia during high-speed reciprocating reversing motion of the machine head, thus improving the operational safety of the quick-change mechanism during production.

[0022] Preferably, the tool holder has a mounting hole for the camshaft to pass through, the camshaft is rotatably connected to the mounting hole, and a sealing ring is provided in the mounting hole to seal both ends of the mounting hole.

[0023] By providing sealing rings inside the mounting hole to seal both ends of the mounting hole, when the equipment performs high-intensity glass cutting operations, the sealing rings form a symmetrical bidirectional sealed barrier at both ends of the mounting hole. This prevents highly abrasive fine glass dust from splashing and spreading throughout the processing area from seeping into the mounting hole along the rotational fit gap of the camshaft. This effectively prevents dust from getting trapped on the camshaft surface and causing abrasive damage, which could lead to rotational jamming or increased fit gap. This further ensures the cleanliness of the core moving parts of the locking mechanism.

[0024] Furthermore, when the operating handle drives the camshaft to rotate to perform the locking or releasing action of the cutter wheel assembly, the sealing rings at both ends always maintain a sliding seal against the outer wall surface of the camshaft. This not only ensures that the lubricating grease stored inside the mounting hole cannot leak outward, maintaining the lightweight operating feel of the camshaft's long-term smooth rotation, but also that the elastic restraint force formed by the symmetrical ends provides stable circumferential and radial limiting constraints for the camshaft. This prevents the camshaft from axial movement or local tilting and shaking when it follows the direction of change or is subjected to high-frequency axial impact loads, thereby ensuring the smoothness of the overall motion transmission of the eccentric locking assembly and the rigid locking accuracy under long-term operation.

[0025] Preferably, both the truncated cone-shaped female hole and the male cone adopt an asymmetrical structure, and the side surface with the slider portion of the male cone has a larger side surface with the arc-shaped locking groove than the side surface with the slider portion.

[0026] By setting both the conical female hole and the male cone to an asymmetrical structure, when the tool wheel assembly is quickly and blindly plugged in and replaced on site, if the tool bar is inserted in the wrong direction, the asymmetrical side profile structure will generate strong spatial geometric interference and obstruction. This avoids mechanical damage to the eccentric locking pair and positioning surface caused by forced assembly of the tool wheel assembly in the wrong direction, effectively prevents glass tangential process defects caused by reversed tool wheel installation direction, and further ensures absolute physical error prevention and initial assembly accuracy of high-frequency quick change operation.

[0027] Furthermore, the side area of ​​the slider portion is configured to be larger than the side area of ​​the locking groove. During the locking operation of the eccentric locking assembly, the camshaft presses against the opposite pressure inclined surface and pushes the male cone laterally in the opposite direction. This causes the larger slider portion side to have a strong, large-area surface contact with the corresponding inner wall of the conical female hole. As the locking force continues to increase, this large-area rigid contact pair forms higher lateral friction damping at the contact interface until the cutter wheel assembly is completely rigidly locked. At this time, the large-area contact surface can disperse and absorb the high-frequency lateral impact load generated during glass cutting, ensuring that the main force surface is not prone to fatigue pitting or dust intrusion grinding due to local stress concentration. At the same time, the large-area asymmetric rigid lateral constraint ensures the torsional limit of the cutter bar under high resistance cutting conditions of glass, avoiding slight deflection or resonant yaw of the cutter wheel assembly in the tangential anti-rotation direction, thereby ensuring the anti-rotation stiffness and final forming quality of high-quality glass products during efficient cutting.

[0028] Preferably, the two sidewalls of the dovetail-shaped guide groove are symmetrically arranged, and the lateral tilt angle of each sidewall relative to the center line of the frustum-shaped conical mother hole is θ, where 10°≤θ≤20°.

[0029] By symmetrically arranging the two sidewalls of the dovetail-shaped guide groove and limiting their lateral tilt angle θ to a specific range of 10° to 20°, when the slider part slides into the guide groove axially for insertion assembly, the symmetrically arranged sidewalls can provide the slider part with a bidirectional balanced lateral geometric constraint force. This avoids unilateral wear or mechanical jamming caused by uneven force on both sides during the high-speed axial advancement of the slider part, effectively preventing local scratches on the mating guide surface or guide failure due to excessive angle, and further ensuring the smoothness of guide alignment throughout the quick-change insertion and removal stroke.

[0030] Furthermore, when the eccentric locking assembly applies a locking force and pushes the slider part forcefully into the guide groove, the two inclined surfaces of the slider part slide and compress relative to the symmetrical sidewalls of the guide groove. As the locking force continues to increase, the wedge effect generated by the tilt angle converts the lateral thrust into a normal clamping force perpendicular to the guide sidewall until the entire tool wheel assembly reaches a rigid positioning dead point. At this time, the slider part remains in a pulled-out blocking state under the restriction of the symmetrical sidewalls of the guide groove, ensuring that the slider part will never radially derail or slightly warp from the guide groove when the external cutting load fluctuates violently. At the same time, the tilt angle ensures the stability of the slider part during the reverse unlocking and extraction process, avoiding lateral jamming or shaking of the tool bar when it exits the positioning inner hole due to the deviation of the direction of the manual pulling force, thereby ensuring the bidirectional stability of the tool wheel assembly when inserting and removing tools and when subjected to high-frequency machining impacts.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention employs a composite structure of eccentric cam over-dead-point locking and conical surface positioning, enabling the rapid disassembly and replacement of the integrated cutting blade wheel under manual operation without the need for additional tools. Compared with the traditional threaded locking structure, this significantly shortens the blade replacement time and effectively improves the production efficiency of continuous glass cutting operations.

[0032] 2. The eccentric locking component, together with the limit stop, achieves self-locking at the dead point, which can convert the impact force generated by the cutting operation into a tendency force to maintain the locking state. Combined with the pre-tightening effect of the torsion spring, it forms a double anti-loosening and anti-vibration structure, which effectively avoids accidental loosening under high-frequency vibration conditions and improves locking reliability.

[0033] 3. By setting up a dust scraper ring in conjunction with a centrally connected blowing and cooling channel, the path of glass dust intrusion into the positioning mating surface and the core moving pair is doubly blocked. This not only avoids grinding damage and tolerance accumulation on the mating surface caused by dust, but also directly cools and reduces dust at the cutting point, thereby improving the service life of the cutting wheel and the quality of the cutting process.

[0034] 4. The asymmetrical conical surface positioning combined with the foolproof structure can avoid incorrect installation direction during manual quick-change operation. At the same time, it increases the contact area of ​​the main force-bearing surface, disperses and absorbs cutting impact load, and improves the torsional stiffness and processing accuracy of the cutter wheel assembly, which can meet the process requirements of high-quality glass cutting.

[0037] Please see Figures 1 to 7 This invention provides a quick-change mounting mechanism for an integrated cutting wheel, the technical solution of which is as follows: For a quick-change mounting mechanism for an integrated cutting blade wheel, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7The system includes a tool holder 1 and a tool wheel assembly. The tool holder 1 has a locating inner hole 101 that extends axially from top to bottom. The lower part of the locating inner hole 101 is configured as a truncated pyramidal conical female hole 1011. A dovetail-shaped guide groove 1012 is axially formed on one side wall of the conical female hole 1011. The two side walls of the dovetail-shaped guide groove 1012 are symmetrically arranged, and the lateral tilt angle of each side wall relative to the center line of the truncated pyramidal conical female hole 1011 is θ, where θ = 12°. The tool wheel assembly includes a tool shank 2 and a tool wheel 3 located at the bottom end of the tool shank 2. The top end of the tool shank 2 is aligned with the conical female hole 1011. A matching male cone 201 is provided. One side of the male cone 201 is provided with a slider part 2011 that matches the guide groove 1012. The truncated cone female hole 1011 and the male cone 201 both adopt an asymmetrical structure. Among the four sides of the male cone 201, the side area with the slider part 2011 is larger than the side area with the arc-shaped locking groove 2012. The upper end of the positioning inner hole 101 is provided with a cooling channel 102. The top center of the tool bar 2 is provided with an exhaust channel 202 that is coaxial with and connected to the cooling channel 102. The exhaust channel 202 passes through the tool bar 2 axially downward and connects directly to the lower end of the tool wheel 3.

[0038] For further details, please refer to Figures 5 to 7 An arc-shaped locking groove 2012 is provided on the opposite side of the male cone 201 and the slider part 2011. The top of the locking groove 2012 is provided with an inwardly downward inclined pressure surface 2013. The tool holder 1 is also provided with an eccentric locking assembly, which includes a camshaft 4 and an operating handle 5. The camshaft 4 is horizontally arranged and rotatably connected to the tool holder 1. One end of the camshaft 4 extends to the outside of the tool holder 1 and is fixedly connected to the operating handle 5. The middle section of the camshaft 4 is provided with an outwardly protruding eccentric driving arc surface 401. The operating handle 5 is used to drive the camshaft. 4. Rotate so that the eccentric drive arc surface 401 cuts into the locking groove 2012 and presses against the pressure inclined surface 2013; the tool holder 1 is provided with a limit stop 6, and the eccentric drive arc surface 401 is configured to rotate to the over-dead point state beyond the maximum eccentricity point under the drive of the operating handle 5. When the eccentric drive arc surface 401 is in the over-dead point state, the operating handle 5 and the limit stop 6 abut against each other. The eccentric locking assembly also includes a torsion spring 8 sleeved on the camshaft 4. The torsion spring 8 is used to provide the operating handle 5 and the camshaft 4 with an initial preload force for rotation toward the locking termination position.

[0039] For further details, please refer to Figure 6 and Figure 7A mounting groove 1013 is formed on the large end face of the conical female hole 1011. A dust scraper ring 7 protruding inward is fixedly installed in the mounting groove 1013. The inner contour of the dust scraper ring 7 is adapted to the outer circumferential surface of the male cone 201, and slides with an interference fit with the outer circumferential surface of the male cone 201 during axial insertion. It should be noted that the dust scraper ring 7 is made of an elastic and wear-resistant material, such as elastic rubber, engineering plastics, or felt composite material. When the male cone 201 is inserted into the conical female hole 1011 axially, the dust scraper ring 7 can automatically... The glass dust and debris adhering to the surface of the male cone 201 are scraped off to prevent the dust-laden male cone 201 from being fully inserted into the positioning mating surface. This prevents the particles from embedding into the tapered mating gap, causing grinding damage and deterioration of positioning accuracy. After the male cone 201 is inserted into the tapered female hole 1011, the tool holder 2 squeezes the dust scraper ring 7 into the mounting groove 1013. The tool holder 1 has a mounting hole 103 for the camshaft 4 to pass through. The camshaft 4 is rotatably connected to the mounting hole 103. The mounting hole 103 has a sealing ring 9 for sealing both ends of the mounting hole 103.

[0040] Working principle: Please refer to Figures 1 to 7 The process mainly consists of four continuous dynamic and structural coordination processes: insertion guidance, eccentric locking self-locking, machining follow-up protection, and reverse unlocking release. In the initial insertion stage, the operator aligns the tool shank 2 of the tool wheel assembly with the lower part of the positioning inner hole 101 of the tool holder 1. Because both the truncated pyramidal conical female hole 1011 and the male cone 201 at the top of the tool shank 2 adopt an asymmetrical structure, it can only slide smoothly in when the side with the slider part 2011 is completely aligned with the side wall with the dovetail guide groove 1012, thus achieving absolute physical anti-foolproof positioning. As the tool shank 2 continues to advance axially inward, the dust scraper ring 7, fixedly installed in the mounting groove 1013 on the large end face of the conical female hole 1011, relies on its internal... The sliding interference fit between the profile dimension and the outer peripheral surface of the male cone 201 allows for hard wiping of the surface of the male cone 201 to thoroughly peel off and scrape away the attached high-hardness glass dust, ensuring extremely high cleanliness of the subsequent mating interface. At the same time, the torsion spring 8 sleeved on the camshaft 4 begins to store energy, providing the entire locking assembly with the initial preload force to rotate towards the locking termination position. Furthermore, when the tool holder 2 is pushed upward to the positioning dead point, the cooling channel 102 of the upper section of the tool holder 1 and the exhaust channel 202 at the top of the tool holder 2 automatically achieve seamless coaxial docking under the constraint of the mechanical reference.

[0041] Then, the locking and self-locking stage begins. The operating handle 5, driven manually or via an external mechanism, rotates the horizontally positioned camshaft 4 within the mounting hole 103. At this time, the sealing rings 9 at both ends of the mounting hole 103 provide smooth circumferential damping while maintaining perfect sealing and preventing dust intrusion. The eccentric drive arc surface 401, protruding outwards from the middle section of the camshaft 4, gradually cuts into the arc-shaped locking groove 2012 on the side of the male cone 201, and presses against the inwardly downward inclined pressure surface 2013. Under the tightening action of the camshaft 4 and the pressure surface 2013, the unidirectional rotational torque is converted into a bidirectional force, with the axial upward force pulling the male cone 201 tight against the tapered female hole 1011. Inside, the radial assembly gap between the two conical surfaces is forcibly eliminated and high-precision coaxial centering is achieved. The lateral radial component force causes the slider 2011 to be pushed tightly into the dovetail guide groove 1012. The wedge effect generated by the symmetrical sidewall inclination angle of the guide groove 1012 is used to amplify the lateral thrust into a normal clamping force perpendicular to the sidewall, so that the two inclined surfaces of the slider 2011 are deeply locked with the symmetrical sidewall of the guide groove 1012. At this time, the operating handle 5 continues to rotate and exceeds the maximum eccentricity point of the cam to enter the over-dead point state, and finally makes rigid contact with the limit block 6 on the tool holder 1, forming a dual anti-vibration self-locking defense system composed of elastic pre-tension of torsion spring 8 and mechanical locking of over-dead point.

[0042] In the subsequent machining follow-up operation, high-pressure cooling airflow is injected from the cooling channel 102 and flows directly to the cutting point of the bottom cutter wheel 3 along the exhaust channel 202. While performing follow-up local cooling on the cutter wheel 3 and the glass interface, the high-pressure airflow ejected from the bottom creates a strong positive pressure blowing zone around the cutter wheel 3 to forcibly remove fine glass dust. The high-frequency axial impact force and tangential torque fluctuation generated by glass cutting not only cannot cause the camshaft 4 to reverse, but will be efficiently dispersed and absorbed by the large-area asymmetric rigid contact surface, and transformed into a tendency force that causes the operating handle 5 to press further against the limit block 6. With the circumferential rigid positioning restriction of the limit block 6 on the operating handle 5, it is ensured that the entire mechanism will not have any lateral slight deflection or mechanical resonance under extremely high cutting resistance, thus ensuring anti-rotation stiffness and the scribing quality of the glass.

[0043] Finally, during the unlocking and release phase when the tool needs to be replaced, the reverse rotation of the operating handle 5 overcomes the torsional resistance of the torsion spring 8 and crosses the dead point. The eccentric drive arc surface 401 smoothly slides out of the arc-shaped locking groove 2012, and the constraint of the camshaft 4 on the pressure inclined surface 2013 is completely released. At this time, since the limit stop 6 restricts the starting point of the locking stroke, the operator can directly and smoothly pull out the tool wheel assembly axially, realizing instantaneous zero-stop quick change without tool intervention.

[0044] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
