Description

Technical Field

[0001] This invention relates to the field of tooth root grinding technology for inner ring gears, and more specifically to a tooth root grinding machine for tooth rings. Background Technology

[0002] The machining of toothed rings involves multiple steps. When machining the teeth, the inner ring side or the outer ring side of the toothed ring needs to be machined depending on the application scenario.

[0003] For example, Chinese Patent Publication No. CN106112400B discloses a method for machining ultra-large diameter multi-segment gear rings. This method details the complete steps of gear ring machining, which include the following process steps: 1. Dividing the blank; 2. Rough turning the end face; 3. Low-temperature tempering; 4. Finish turning the end face; 5. Milling the outer circle or inner hole; 6. Drilling; 7. Gear machining. The workpiece is fixed on a fixture, and gear machining is performed on a gear shaper. After machining, the gear ring is inspected, and all dimensions meet the drawing requirements, thus completing the machining process.

[0004] The above solution describes the tooth machining steps, which are basically consistent with the existing tooth machining process. However, in order to improve the precision of the teeth in the gear, the tooth roots usually need to be ground immediately after the teeth on the gear are turned. Specifically, for the teeth on the outer ring side of the gear ring, grinding wheels or spiral grinding rollers are mainly used for grinding, while for the teeth on the inner ring side of the gear ring, broaching is mainly used. During grinding, the grinding head reciprocates to achieve the grinding effect on the tooth roots on the inner ring side of the gear ring. However, the following problems exist when grinding the tooth roots on the inner ring side of the gear ring: First, the size and shape of the teeth on the inner ring side of different toothed rings vary. Therefore, a corresponding grinding head needs to be selected to complete the grinding work. However, the replacement of existing grinding heads requires manual operation, which is cumbersome and inefficient. Second, grinding heads will wear down after long-term use. Manually inspecting the wear of each grinding head is a huge workload and prone to errors. Specialized inspection tools and inspection workbenches are needed for inspection, which is also inefficient. If an excessively worn grinding head is mistakenly used to grind the toothed ring due to human error, the grinding effect will be poor and the product will not meet the standards. Summary of the Invention

[0005] To address the aforementioned issues, a tooth root grinding machine for gear rings is provided. By housing multiple grinding blades within a tool magazine and coordinating with a drive unit to achieve synchronous movement of all blades, the machine can quickly move the grinding blade matching the gear ring body to the mounting position, eliminating the need for manual selection. This simplifies the selection process, effectively improves grinding blade replacement efficiency, and solves the problems of cumbersome and inefficient manual replacement in existing technologies. The clamping unit enters the mounting position via its clamping end to complete the clamping and replacement of the grinding blade, reducing manual labor intensity. A detection unit located at the mounting position can promptly detect grinding blade wear without the need for specialized tools, reducing manual workload and errors. This prevents substandard products caused by misusing excessively worn grinding blades, while also verifying the accuracy of replacement and reading initial values ​​for subsequent testing.

[0006] To address the problems of the prior art, the present invention provides a tooth root grinding machine for tooth rings, including a clamping seat for supporting and holding the tooth ring body; The tooth root grinding machine also includes: A tool magazine is horizontally disposed on the upper part of the clamping base. The tool magazine contains a plurality of grinding blades arranged along the length of the tool magazine. A drive unit for driving all the grinding blades to move synchronously is horizontally disposed at one end of the tool magazine. The tool magazine is provided with a mounting position. A clamping unit is provided on one side of the tool magazine. The lower part of the clamping unit is a clamping end, which can enter the mounting position to clamp and replace the grinding tool. The detection unit is located at the mounting position of the tool magazine and is used to detect the wear of the grinding tool.

[0007] Preferably, the grinding blade comprises: The support base can be directly connected to the clamping end of the clamping unit; The cutting head is detachably coupled to the support base.

[0008] Preferably, the lower part of the cutter head is chamfered.

[0009] Preferably, the tool magazine is further provided with: The tool holder is slidably disposed within the tool magazine along the extension direction of the tool magazine, and the drive unit is directly connected to the tool holder; The tool holder has multiple placement slots that are evenly spaced along the extension direction of the tool magazine, and the placement slots are used to place the grinding tool.

[0010] Preferably, the clamping unit includes: A first linear actuator is horizontally disposed on one side of the tool magazine and is used to drive the tool magazine to move horizontally; A fixing component is vertically movable on one side of the tool magazine. The fixing component has a highest position when it is raised and lowered. When the tool magazine moves horizontally and the fixing component is in the highest position, the fixing component can slide into the mounting position. The support base has a slot on its side wall, and the slot is inserted into the fixing component.

[0011] Preferably, the fixing component includes: The insert block is inserted into the slot. A lifting groove is vertically formed on the upper part of the insertion block; The locking block is vertically movable and positioned within the lifting groove; An air pump is located on one side of the insert block and communicates with the lifting groove; The top of the slot has a vertical locking groove, which is inserted into the locking block.

[0012] Preferably, the clamping unit further includes: The second linear actuator is vertically mounted on the upper part of the fixed component and is used to drive the fixed component to move up and down.

[0013] Preferably, the detection unit includes: An electric actuator is horizontally positioned on the side of the mounting position away from the clamping unit; A detection head is disposed at the end of the electric actuator, and the detection head is pressure-sensitive.

[0014] Preferably, the electric actuator is a Hall effect type.

[0015] Preferably, a replacement port is provided on the side wall of the tool magazine.

[0016] The advantages of this invention compared to the prior art are: 1. This invention, by setting multiple grinding blades in the tool magazine and cooperating with the drive unit to achieve synchronous movement of all grinding blades, can quickly move the grinding blade matching the gear ring body to be processed to the mounting position, eliminating the need for manual selection, simplifying the selection process, effectively improving the grinding blade replacement efficiency, and solving the problems of cumbersome and inefficient manual replacement in the prior art. The clamping unit enters the mounting position through the clamping end to complete the clamping and replacement of the grinding blade, reducing the intensity of manual operation; the detection unit is located in the mounting position, which can detect the wear of the grinding blade in a timely manner without the need for special tools, reducing manual workload and errors, avoiding product substandard due to the misuse of excessively worn grinding blades, and at the same time verifying the accuracy of replacement and reading the initial values, providing a reference for subsequent testing, improving grinding efficiency, accuracy and stability, and ensuring the quality of gear ring processing.

[0017] 2. By setting the grinding cutter to a structure where the support base and the cutter head can be detachably coupled, when the detection unit detects excessive wear of the cutter head, it is not necessary to replace the entire grinding cutter; only the worn cutter head needs to be replaced. This avoids material waste and reduces equipment maintenance costs. The chamfer set at the lower part of the cutter head allows the cutter head to smoothly conform to the tooth root contour, avoiding jamming during grinding, reducing cutter head wear and tooth root grinding defects, extending the service life of the cutter head, further reducing maintenance and operating costs, and ensuring smooth grinding and precision of gear ring machining.

[0018] 3. Through the coordinated operation of the various components of the clamping unit and the optimized design of the detection unit, the clamping, unlocking, and wear detection of the grinding blade are automated. The Hall effect electric actuator improves the detection accuracy and stability. The setting of the replacement port simplifies the grinding blade replacement operation. The blade holder and placement slot ensure the stability of the grinding blade movement and the versatility of the equipment. The overall equipment structure is optimized, the intensity of manual operation is reduced, the reliability and practicality of equipment operation are improved, and the grinding operation is ensured to be carried out continuously and efficiently.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 to 4 A tooth root grinding machine for tooth rings includes a clamping seat 1 for supporting and holding the tooth ring body 2; The tooth root grinding machine also includes: The tool magazine 3 is horizontally disposed on the upper part of the clamping base 1. The tool magazine 3 is provided with a plurality of grinding blades 31 arranged along the length direction of the tool magazine 3. A drive unit 32 for driving all the grinding blades 31 to move synchronously is horizontally disposed at one end of the tool magazine 3. The tool magazine 3 is provided with a mounting position 33. The clamping unit 4 is located on one side of the tool magazine 3. The lower part of the clamping unit 4 is the clamping end, which can enter the mounting position 33 to clamp and replace the grinding tool 31. The detection unit 5 is located at the mounting position 33 of the tool magazine 3 and is used to detect the wear of the grinding tool 31.

[0030] The drive unit 32 is a linear drive type. There are many types of existing linear drive units 32, such as electric cylinders and slides, which can be selected according to needs.

[0031] When grinding the tooth roots of the gear ring body 2, the gear ring body 2 is first placed horizontally on the clamping seat 1, which supports and clamps the gear ring body 2. Then, the drive unit 32 is started, which drives all the grinding cutters 31 in the tool magazine 3 to move synchronously along the length of the tool magazine 3, so that the grinding cutters 31 pass through the mounting positions 33 on the tool magazine 3 in sequence. When the grinding cutter 31 that matches the gear ring body 2 being processed moves to the mounting position 33, the drive unit 32 stops running. At this time, the clamping unit 4 is started, and the clamping end of the clamping unit 4 enters the mounting position 33 to clamp the grinding cutter 31 located at the mounting position 33. After clamping, the clamping unit 4 drives the grinding cutter 31 to perform grinding operations on the tooth roots of the gear ring body 2 on the clamping seat 1.

[0032] After the grinding operation is completed, the clamping unit 4 moves the used grinding blade 31 back to the mounting position 33. The detection unit 5, located at the mounting position 33, detects the wear condition of the grinding blade 31 to determine whether it meets the requirements for continued use. If the detection unit 5 detects that the grinding blade 31 is worn and needs to be replaced, the drive unit 32 is activated after the clamping unit 4 releases the grinding blade 31, driving all grinding blades 31 to move synchronously. The grinding blade 31 that needs to be replaced is moved to a suitable position. After the replacement of the grinding blade 31 is completed, the drive unit 32 moves the replaced grinding blade 31 back to the mounting position 33. The detection unit 5 then detects the replaced grinding blade 31. Once it is confirmed that it meets the usage requirements, the next grinding operation can be performed.

[0033] The tooth root grinding machine for toothed rings uses a clamping seat 1 to stably support and hold the toothed ring body 2, providing a solid foundation for tooth root grinding operations and ensuring grinding accuracy. The tool magazine 3 contains multiple grinding blades 31, which, in conjunction with the drive unit 32, enable the synchronous movement of all grinding blades 31. This allows for the rapid movement of the grinding blade 31 that matches the toothed ring body 2 to the mounting position 33, eliminating the need for manual selection of the appropriate grinding blade 31. This simplifies the selection process, effectively improves the efficiency of grinding blade replacement, and solves the problems of cumbersome and inefficient manual replacement of grinding blades 31 in existing technologies. The clamping unit 4 can access the mounting position 33 through its clamping end to clamp and replace the grinding blades 31. This further optimizes the replacement operation of the grinding cutter 31, reducing the intensity of manual operation. The detection unit 5 is set at the installation position 33, which can detect the wear of the grinding cutter 31 in time after use without the need for special detection tools and detection workbench, reducing the workload of manual detection, avoiding errors that are prone to occur in manual detection, and preventing poor grinding effect and substandard products due to the misuse of excessively worn grinding cutter 31. At the same time, it can also detect the accuracy of the replacement of grinding cutter 31 and read the initial value of grinding cutter 31 in time after replacement, providing a reliable reference for subsequent wear detection of grinding cutter 31, improving the efficiency, accuracy and stability of tooth root grinding of gear rings, and ensuring the processing quality of gear ring products.

[0034] Reference Figure 7 and Figure 8 The grinding blade 31 includes: The support base 311 can be directly connected to the clamping end of the clamping unit 4; The cutter head 312 is detachably coupled to the support base 311.

[0035] The grinding cutter 31 is directly connected to the clamping end of the clamping unit 4 via the support base 311, enabling the clamping unit 4 to stably clamp and drive the grinding cutter 31, ensuring that the grinding cutter 31 will not loosen during the grinding operation and guaranteeing grinding accuracy. Since the cutter head 312 and the support base 311 are detachably connected, when the detection unit 5 detects that the cutter head 312 is excessively worn and needs to be replaced, it is not necessary to remove and replace the entire grinding cutter 31. Only the worn cutter head 312 needs to be removed from the support base 311 and replaced with a new cutter head 312. This avoids the material waste caused by replacing the entire grinding cutter 31 and reduces the maintenance cost of the equipment.

[0036] Reference Figure 7 The lower part of the cutter head 312 is chamfered.

[0037] When the clamping unit 4 drives the grinding cutter 31 to grind the tooth root of the gear ring body 2, the lower part of the cutter head 312 directly contacts the tooth root of the gear ring body 2. Because the lower part of the cutter head 312 has a chamfer, it can smoothly conform to the tooth root contour when contacting and grinding, preventing jamming. This avoids problems such as accelerated wear of the cutter head 312 or scratches and dimensional deviations in the tooth root grinding caused by jamming, ensuring the smoothness and precision of the tooth root grinding. At the same time, the chamfer structure also reduces the impact force when the cutter head 312 contacts the tooth root, reducing the wear rate of the cutter head 312, extending its service life, and reducing the frequency of cutter head 312 replacement. This further reduces labor maintenance costs and equipment operating costs, indirectly improving the grinding efficiency of the gear ring tooth root and ensuring that the ground gear ring product meets quality requirements.

[0038] Reference Figure 6 The tool magazine 3 is also equipped with: The tool holder 34 is slidably disposed in the tool magazine 3 along the extending direction of the tool magazine 3, and the drive unit 32 is directly connected to the tool holder 34; The placement slots 341 are multiple and are evenly distributed on the tool holder 34 along the extension direction of the tool compartment 3. The placement slots 341 are used to place the grinding tool 31.

[0039] The drive unit 32 is directly connected to the tool holder 34, which drives the tool holder 34 to slide along the extension direction of the tool magazine 3. Multiple grinding tools 31 are placed in multiple placement slots 341 on the tool holder 34. When the drive unit 32 drives the tool holder 34 to move, it can drive all the grinding tools 31 to move synchronously along the extension direction of the tool magazine 3. This achieves the effect of the grinding tools 31 passing through the mounting position 33 in sequence, ensuring that the grinding tool 31 that matches the gear ring body 2 to be processed can be quickly moved to the mounting position 33. This simplifies the selection and movement operation of the grinding tool 31 and improves the switching efficiency of the grinding tool 31. The placement slots 341 can position and fix the grinding cutter 31, preventing the grinding cutter 31 from shaking or shifting during the movement of the tool holder 34, ensuring the stability of the grinding cutter 31 during movement, and avoiding problems such as difficulty in subsequent clamping or reduction in grinding accuracy caused by the shift of the grinding cutter 31. At the same time, the multiple placement slots 341 are evenly arranged, which can rationally plan the space in the tool magazine 3, making it easy to accommodate multiple grinding cutters 31 of different specifications, meeting the grinding needs of different sizes and tooth shapes, and further improving the versatility of the equipment.

[0040] Reference Figure 7 and Figure 8 The clamping unit 4 includes: The first linear actuator 41 is horizontally disposed on one side of the tool magazine 3 and is used to drive the tool magazine 3 to move horizontally. The fixing component 42 is vertically movable and disposed on one side of the tool magazine 3. The fixing component 42 has a highest position when it is raised and lowered. When the tool magazine 3 moves horizontally and the fixing component 42 is in the highest position, the fixing component 42 can slide into the mounting position 33. The support base 311 has a slot 3111 on its side wall, and the slot 3111 is inserted into the fixing component 42.

[0041] When it is necessary to clamp the grinding tool 31, the fixing component 42 is first raised and lowered to its highest position. Then, the first linear actuator 41 is activated, which drives the tool magazine 3 to move horizontally toward the fixing component 42, so that the fixing component 42, which is at its highest position, slides into the mounting position 33 of the tool magazine 3. At this time, the fixing component 42 engages with the slot 3111 on the side wall of the grinding tool support 311, realizing the initial positioning and clamping of the grinding tool 31 by the fixing component 42, ensuring that the clamping unit 4 can stably drive the grinding tool 31 to perform the grinding operation. After the grinding operation is completed, the fixing component 42 is raised to its highest position, and the first linear actuator 41 is activated to drive the tool magazine 3 toward the fixing component 42. When the grinding tool 31, which is fixed by the fixing component 42, enters the mounting position 33, the fixing component 42 separates from the grinding tool 31. Before separation, the detection unit 5 detects the wear condition of the grinding tool 31. This clamping method eliminates the need for manual operation of the fixing component 42 and the grinding blade 31. Through the driving of the first linear actuator 41 and the lifting of the fixing component 42, the clamping and unclamping of the grinding blade 31 is automated, simplifying the operation steps and improving clamping efficiency. When the grinding blade 31 grinds the tooth root of the tooth ring body 2, the first linear actuator 41 is not subjected to vertical force, avoiding damage to the first linear actuator 41. At the same time, the insertion and engagement of the slot 3111 and the fixing component 42 ensures the stability of the clamping, prevents the grinding blade 31 from loosening during the grinding process, and ensures the grinding accuracy. This further solves the problems of cumbersome and inefficient manual clamping of the grinding blade 31 in the prior art.

[0042] Reference Figure 8 The fixing component 42 includes: The insert 421 is inserted into the slot 3111; The lifting groove 422 is vertically formed on the upper part of the insert block 421; The locking block 423 is vertically movable and disposed in the lifting groove 422; An air pump 424 is disposed on one side of the insert block 421 and communicates with the lifting groove 422; The top of the slot 3111 is vertically provided with a locking groove 3112, which is engaged with the locking block 423.

[0043] When the fixing component 42 slides into the mounting position 33 and is inserted into the slot 3111 of the support base 311, the insert block 421 is first inserted into the slot 3111 to achieve the initial insertion and positioning of the fixing component 42 and the grinding blade 31. Then, the air pump 424 is started, and the air pump 424 inflates the lifting groove 422 on the upper part of the insert block 421, pushing the locking block 423 in the lifting groove 422 to rise vertically, so that the locking block 423 extends out of the lifting groove 422 and inserts into the locking groove 3112 at the top of the slot 3111, thereby achieving the locking and fixing of the fixing component 42 and the support base 311, further improving the stability of the clamping, preventing the grinding blade 31 from loosening or shifting due to force during the grinding operation, and ensuring the grinding accuracy. When it is necessary to release the clamp, the air pump 424 draws air, and the locking block 423 falls back into the lifting groove 422, disengaging from the locking groove 3112. At this time, the insert block 421 can be pulled out from the slot 3111, realizing the separation of the fixing component 42 from the grinding blade 31. This locking structure, driven by the air pump 424 to lift the locking block 423, automates clamping and unlocking, eliminating the need for manual locking or unlocking, further simplifying the operation steps and improving clamping and disassembly efficiency. At the same time, the insertion and cooperation between the locking block 423 and the locking groove 3112 effectively enhances the clamping firmness, preventing the grinding blade 31 from falling off during the grinding process, ensuring the safety of equipment operation and the stability of the grinding operation, and further optimizing the clamping effect of the grinding blade 31.

[0044] Reference Figure 3 and Figure 4 The clamping unit 4 further includes: The second linear actuator 43 is vertically disposed on the upper part of the fixed component 42 and is used to drive the fixed component 42 to rise and fall.

[0045] The second linear actuator 43 is vertically mounted on the upper part of the fixed assembly 42 and is responsible for driving the fixed assembly 42 to move up and down in the vertical direction, thereby switching between the highest position of the fixed assembly 42 and the grinding operation position. When it is necessary to clamp or remove the grinding tool 31, the second linear actuator 43 drives the fixed assembly 42 to rise to the highest position, ensuring that when the tool magazine 3 moves in the horizontal direction, the fixed assembly 42 can smoothly slide into or out of the mounting position 33.

[0046] Reference Figure 6 The detection unit 5 includes: The electric actuator 51 is horizontally positioned on the side of the mounting position 33 away from the clamping unit 4; The detection head 52 is disposed at the end of the electric actuator 51, and the detection head 52 is pressure-sensitive.

[0047] The electric actuator 51 can automatically detect its own extension length. Taking the detection head 52 as an example, before detection, a wear threshold is preset for the grinding blade 31. If the grinding blade 31 is an unused and newly replaced blade, the electric actuator 51 needs to detect the grinding blade 31. The electric actuator 51 pushes the detection head 52 closer to the grinding blade 31. When the detection head 52 contacts the grinding blade 31, the electric actuator 51 stops moving, and the processor records the extension length of the electric actuator 51 at this time and zeros it. The grinding blade 31 will experience wear after use. Each time it is used up, the electric push rod 51 pushes out the detection head 52, so that the detection head 52 contacts the blade head 312 of the grinding blade 31 in the mounting position 33, and records the extension length of the end of the electric push rod 51 to determine the wear condition of the grinding blade 31. The wear value of the blade head 312 is the difference between the actual extension length of the electric push rod 51 and the extension length when the electric push rod 51 is zeroed. If the wear value of the blade head 312 is greater than the wear threshold, it means that the blade head 312 needs to be replaced.

[0048] As a supplement, the detection head 52 can be telescopic and multiple can be set. Since the existing toothed rings mainly have triangular and trapezoidal structures, multiple detection heads 52 can be set according to the tooth shape of different toothed rings to detect the wear of different tooth surfaces on the same tooth. The self-retracting detection head 52 can adapt to the tooth surface after contacting the tooth. When all detection heads 52 detect the same tooth together, the detection data of multiple detection heads 52 can achieve the effect of detecting the wear of different tooth surfaces in the same tooth, thereby improving the accuracy of wear detection of the grinding tool 31.

[0049] The entire testing process requires no manual operation or specialized testing tools and workbenches, achieving automation and precision in the wear detection of the grinding tool 31. This reduces manual workload, improves testing efficiency, and ensures the continuity of grinding operations and the processing quality of gear ring products.

[0050] Reference Figures 1 to 8 The electric actuator 51 is a Hall effect type.

[0051] The Hall effect actuator 51 in detection unit 5 is a Hall effect type. Utilizing its self-checking extension length function, the accuracy and stability of wear detection for the grinding cutter 31 are further improved. When detecting the grinding cutter 31, the Hall effect actuator 51 can accurately detect its own extension length, eliminating the need for additional length detection components, simplifying the structure of detection unit 5 and reducing manufacturing costs. Simultaneously, the Hall effect actuator 51 boasts high self-checking accuracy and fast response speed, quickly and accurately recording the extension length when in contact with the grinding cutter 31. Whether performing zeroing detection on a new grinding cutter 31 or wear detection on a used grinding cutter 31, it ensures the accuracy of the detection data, reduces detection errors, and avoids misjudging the wear condition of the grinding cutter 31 due to data deviation. This prevents the misuse of excessively worn cutting heads 312 or the mistaken replacement of unworn cutting heads 312, ensuring the quality of gear ring grinding while reducing the replacement cost and manual maintenance workload of cutting heads 312. This further optimizes the detection effect of detection unit 5 and improves the overall operational stability and reliability of the equipment.

[0052] Reference Figure 5 The tool compartment 3 has a replacement port 35 on its side wall.

[0053] A replacement port 35 is provided on the side wall of the tool magazine 3, mainly for replacing the grinding cutter 31. This solves the problem of cumbersome and inefficient replacement of the grinding cutter 31 in the prior art. When the detection unit 5 detects that the cutting head 312 of the grinding cutter 31 is excessively worn and needs to be replaced, the drive unit 32 drives the tool holder 34 to move, moving the grinding cutter 31 to be replaced to the replacement port 35. The operator can directly remove the worn grinding cutter 31 or cutting head 312 from the replacement port 35 without disassembling the tool magazine 3 or other parts, simplifying the replacement operation of the grinding cutter 31 and improving the replacement efficiency. At the same time, the setting of the replacement port 35 makes it easy for the operator to observe the storage and usage status of the grinding cutters 31 in the tool magazine 3, making it easy to detect abnormalities of the grinding cutters 31 in a timely manner, and to carry out maintenance and replacement. This reduces the difficulty and workload of manual operation, ensures that the grinding operation can be carried out smoothly and continuously, further improves the practicality and ease of operation of the equipment, and guarantees the efficiency and quality of tooth ring and tooth root grinding.

[0054] Working principle: When grinding the tooth root of the tooth ring, the main purpose is to remove burrs and other imperfections at the tooth root using the grinding cutter 31, thereby improving the precision of the tooth ring. Before use, the tooth ring body 2 needs to be placed horizontally on the clamping seat 1, and the clamping seat 1 should hold the tooth ring body 2. At the same time, the tooth ring data, such as the diameter of the tooth ring, the number of teeth on the tooth ring, the tooth shape, and the size of the teeth, should be entered into the tooth root grinding machine.

[0055] Subsequently, the drive unit 32 at the end of the tool magazine 3 is activated, pushing the tool holder 34 to move within the tool magazine 3. The tool holder 34 drives all the grinding cutters 31 to move synchronously. As the grinding cutters 31 move with the tool holder 34, they pass sequentially from the mounting position 33 of the tool magazine 3. When the grinding cutter 31 that matches the gear ring being machined moves to the mounting position 33, the drive unit 32 stops operating, and the grinding cutter 31 is in a clamping state at the mounting position 33. At this time, the fixing component 42 in the clamping unit 4 is on the horizontal side of the mounting position 33. The tool magazine 3 is driven by the first linear actuator 41 to move horizontally, causing the tool magazine 3 to move closer to the fixing component 42. Finally, the fixing component 42 slides into the mounting position 33. When the fixing component 42 slides in, the locking block 423 in the lifting groove 422 does not rise. The insert block 421 first inserts into the slot 3111, and then... The first linear actuator 41 stops operating, the locking block 423 is located directly below the locking groove 3112, the air pump 424 starts, and when the air pump 424 inflates the lifting groove 422, the locking block 423 extends from the upper part of the lifting groove 422 and inserts into the locking groove 3112. At this time, the fixing component 42 and the support base 311 are locked. The first linear actuator 41 drives the tool magazine 3 to move in the opposite direction. Since the grinding blade 31 at the mounting position 33 is locked by the fixing component 42, when the tool magazine 3 moves in the opposite direction under the drive of the first linear actuator 41, the grinding blade 31 will slide out from the mounting position 33. Then the second linear actuator 43 drives the fixing component 42 to descend. Since the lower part of the blade head 312 is chamfered, the grinding blade 31 is not prone to jamming when the lower part of the blade head 312 grinds the tooth root on the tooth ring body 2.

[0056] After the clamping unit 4 drives the grinding cutter 31 to grind the tooth roots on the gear ring body 2 one by one, the second linear actuator 43 drives the fixing component 42 to rise to the highest position. At this time, the fixing component 42 is located on the horizontal side of the mounting position 33. Then, the first linear actuator 41 drives the tool magazine 3 to move closer to the fixing component 42, so that the used grinding cutter 31 slides into the mounting position 33. The grinding cutter 31 that has slid into the mounting position 33 is now in the placement slot 341 of the tool holder 34. At this time, the detection unit 5 detects the cutting head 312 of the used grinding cutter 31 to determine the wear condition of the cutting head 312. If the wear value of the cutting head 312 is greater than the preset wear threshold, the cutting head 312 needs to be replaced. Before replacement, the fixing component 42 needs to be completely unlocked from the grinding cutter 31. Then, the drive unit 32 pushes the tool holder 34 to move, so that the grinding cutter 31 to be replaced moves to the replacement port 35. The operator can then remove the grinding cutter 31 to be replaced from the replacement port 35.

[0057] After replacement, the grinding blade 31 is driven by the drive unit 32 to the mounting position 33, where it undergoes a secondary inspection by the detection unit 5. This secondary inspection serves two purposes: First, it determines whether the grinding blade 31 replaced by the operator was incorrect. If the operator did not replace it with an excessively worn grinding blade 31, the value detected by the detection unit 5 during the secondary inspection will be essentially consistent with the value detected before replacement, thus avoiding incorrect replacement of the grinding blade 31 due to human error. Second, the secondary inspection of the replaced grinding blade 31 allows the detection unit 5 to read the initial value of the replaced grinding blade 31, enabling it to zero out and provide a reference value for subsequent inspections.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
