Description

Technical Field

[0001] The present invention relates to the field of metal seal production and processing equipment, and particularly to a processing equipment and method for metal seals. Background Art

[0002] Metal seals are mostly thin-walled circular ring structures, whose function is to build a tight sealing interface between mechanical components, effectively prevent leakage of fluid media such as liquids and gases, ensure the stability of the system pressure, and at the same time prevent intrusion of external impurities such as dust and moisture. In the existing field of metal seal processing, when machining the inner and outer circumferential surfaces of circular ring seals, a split clamping tooling and a manual switching operation mode are generally adopted. Specifically, traditional processing equipment is mostly equipped with single-function inner circle or outer circle jigs. When it is necessary to switch the machining of the inner and outer walls of the circular ring seal, the operator must first stop the machine, loosen the jig, completely remove the workpiece from the jig, remove the position obstruction of the workpiece on the jig adjustment, and then replace the suitable inner circle or outer circle jig, and reposition and clamp the workpiece. Since such processing equipment involves frequent manual loading and unloading and removal of the workpiece, the production efficiency is significantly reduced, and the single switching process takes a long time. At the same time, due to the fixed height of the jig, when taking and placing the workpiece, it is necessary to move the upper processing tool upward to create a space for the workpiece to be taken out of the jig upward, which exacerbates the tediousness of disassembling and replacing the workpiece inside the processing machine tool with a compact size and is not convenient to use. Summary of the Invention

[0003] The purpose of the present invention is to provide a processing equipment and method for metal seals to solve the above problems, drive the clamping part to rotate and move horizontally in the commutation groove, quickly switch the position of the chuck, replace the traditional manual workpiece taking and jig adjusting operation, shorten the clamping and switching time for machining the inner and outer circles of the seal, and improve the production efficiency. When disassembling and assembling the workpiece, the clamping part can be rotated to the horizontal state and then hidden in the commutation groove, without the need to move the tool upward to create space, simplifying the process of taking and placing the workpiece and making the operation more convenient, as described in detail below.

[0004] To achieve the above object, the present invention provides the following technical solutions: A processing equipment for metal seals provided by the present invention includes a base, a clamping table and multiple groups of clamping parts. The clamping table is arranged on the base. A sleeve rod for supporting the rotation of the clamping part is arranged inside the clamping table, and a transmission component for supporting the sleeve rod to drive the clamping part to move radially along the clamping table is arranged in the middle of the clamping table; The clamping part includes a chuck and a core rod. The chuck includes an outer circumferential clamping plate and an inner circumferential clamping plate connected vertically. The clamping part can rotate to switch the up and down positions of the outer circumferential clamping plate and the inner circumferential clamping plate, so as to clamp the inner circumference or the outer circumference of the circular ring seal. The core rod can rotate inside the sleeve rod. A commutation groove for accommodating the chuck is arranged on the clamping table. When the clamping part rotates to the horizontal state, it can be hidden in the commutation groove of the clamping table.

[0005] Preferably, a clamping motor is fixed on one side of the top of the base, and a rotating table is fixed on the top of the base. A synchronous ring is arranged between the base and the clamping table, and the rotating table is used to support the synchronous ring to rotate.

[0006] Preferably, a synchronous gear ring is coaxially arranged on the top side of the synchronous ring, and a driving gear meshing with the synchronous gear ring is arranged at the output end of the clamping motor. The clamping motor drives the synchronous gear ring through the driving gear to drive the synchronous ring to rotate.

[0007] Preferably, an installation groove for accommodating a transmission component is further arranged on the clamping table. The transmission component includes an installation frame and a transmission gear. The installation frame is fixed inside the installation groove, and the transmission gear is rotatably arranged in the installation frame. Multiple groups of the transmission gears are all meshed with the synchronous gear ring to achieve synchronous transmission.

[0008] Preferably, the sleeve rod penetrates through the installation frame, and a constraint block is fixed inside the installation frame. Multiple groups of constraint grooves are arranged on the outer circumference of the sleeve rod corresponding to the constraint block, and the constraint block is in sliding fit with the constraint grooves to support the sleeve rod to drive the whole clamping part to slide radially along to realize the gathering and expansion of the chucks.

[0009] Preferably, the sleeve rod penetrates through the transmission gear, and the sleeve rod is in threaded fit with the transmission gear to utilize the rotation of the transmission gear to drive the sleeve rod to slide radially along the clamping table.

[0010] Preferably, it further includes a control part. The control part is a cylinder or an electric push rod. A fixed column is arranged on the top side of the clamping table. A fixed ear of the control part is arranged at the fixed end of the control part, and the fixed column is used to support the fixed ear of the control part to rotate.

[0011] Preferably, it further includes an adjusting ring and an extension frame. The adjusting ring can rotate in a guiding groove outside the clamping table. The traction frame at the telescopic end of the control part is hinged with a connection hole of the adjusting ring to drive the adjusting ring to rotate by pulling the adjusting ring through the control part. The extension frame includes a support plate fixed on the top side of the clamping table. The outer end of the support plate is bent downward to form a support ear for accommodating the core rod to pass through. A rotating sleeve sleeved outside the core rod is rotatably arranged inside the support ear.

[0012] Preferably, a support groove is arranged on the core rod. A support block in sliding fit with the support groove is fixed inside the rotating sleeve. A positioning gear ring is arranged on the outer circumference of the adjusting ring, and a positioning gear meshing with the positioning gear ring is fixed on the end face of the rotating sleeve.

[0013] The present invention also provides a processing method for a metal seal, including the following steps: S1: Fix the base to the processing equipment through the assembly groove by bolts, such as fixing it on the installation base surface of the workbench of a lathe, and then place the ring seal between multiple clamping parts of the clamping table; S2: According to the situation of the part to be processed on the ring seal, contract the telescopic end of the control part, thereby pulling the adjustment ring to rotate, and use the positioning gear ring of the adjustment ring to drive the positioning gears of multiple extension frames to rotate synchronously, so as to rotate the core rod through the support blocks inside multiple rotating sleeves. According to the required clamping position of the ring seal, rotate the outer circumferential clamping plate or the inner circumferential clamping plate of the chuck to the upward state to complete the rotation preparatory clamping action of the chuck; S3: Start the clamping motor, drive the synchronous gear ring of the synchronous ring to rotate through the driving gear at the output end of the clamping motor, keep the synchronous gear ring meshed with multiple transmission gears, and then drive multiple transmission gears to rotate synchronously. The transmission gears rotate smoothly in the transmission frame. Due to the threaded cooperation between the transmission gear and the sleeve rod, and the sliding cooperation between the constraint block and the constraint groove, use the constraint block to slide-guide the sleeve rod, restrict the sleeve rod to only translate and slide along the radial direction of the clamping table, so that the sleeve rod drives the clamping part to move along the radial direction of the clamping table, realize the gathering or outward expansion of the chuck, clamp and fix the ring seal, and complete the clamping and supporting action of the chuck on the ring seal; S4: When it is necessary to switch the clamping and processing of the inner circumference or outer circumference of the ring seal, first start the clamping motor to loosen the clamping state of multiple clamping parts on the ring seal. Specifically, if the ring seal is in the state of clamping the outer circle, drive multiple chucks to expand outward; if the ring seal is in the state of clamping the inner circle, drive multiple chucks to gather inward, that is, move the chucks radially to separate them from the ring seal. Then start the control part, drive the adjustment ring to rotate by driving the traction frame by the control part, so as to drive the positioning gear on the end face of the rotating sleeve to rotate by using the positioning gear ring of the adjustment ring, and make the support blocks inside multiple rotating sleeves support the core rod to drive the chuck to rotate, so as to drive the chucks of multiple clamping parts to rotate synchronously; Drive the core rod of the clamping part to drive the chuck to rotate to the horizontal state in the sleeve rod, so that the chuck is hidden in the commutation groove of the clamping table. At this time, when the whole chuck moves along the radial direction of the clamping table in the commutation groove, it is ensured that the ring seal placed above will not hinder the sliding movement of the chuck, that is, there is no need to remove workpieces such as the ring seal to switch the positions of the inner and outer wall fixtures; After completing the rotation and hiding action of the chuck in the commutation groove, start the clamping motor again, drive the synchronous gear ring of the synchronous ring to rotate by using the driving gear of the clamping motor, drive the transmission gears of multiple transmission components to rotate by using the synchronous gear ring, so as to utilize the threaded cooperation between the transmission gear and the sleeve rod, and combine the sliding guiding action of the constraint block on the constraint groove, so as to drive the sleeve rod to drive the clamping part to move along the radial direction of the clamping table through the transmission component, change the radial position of the clamping part, and adjust the relative position between the chuck and the ring seal; After moving into place, the control part pulls the adjusting ring to rotate again, thereby driving the clamping ring at one end of the core rod support chuck to rotate and extend out of the commutation groove, causing one set of clamping plates to rotate and switch to the upward working position. Then, the clamping heads of multiple clamping parts are gathered or expanded through the transmission component again, so as to complete the clamping action of switching between the inner and outer walls of the circular ring seal without taking the part.

[0014] The beneficial effects are as follows: 1. By driving the clamping part to rotate and horizontally move in the commutation groove, the up and down position switching of the clamping head can be realized, so as to quickly meet the replacement action of the inner circle fixture and the outer circle fixture, avoid the tediousness of the traditional equipment that requires manual part taking and then adjusting the fixture position, shorten the clamping position switching process time when the inner and outer circles of the circular ring seal are processed in sequence, and improve the production efficiency. 2. At the same time, when disassembling and assembling the workpiece, the multiple clamping parts are directly rotated to the horizontal state quickly to realize the hidden action of the fixture in the commutation groove, without the need to move the machining tool upward to leave space for the workpiece to be taken out upward from the fixture, simplifying the operation process of taking and placing parts in the machining process and making it more convenient to use. 3. In addition, by rotating and switching the inner and outer circumferential clamping plates of the clamping part and adjusting the radial position, it can quickly adapt to the processing requirements of circular ring seals with different size specifications, without the need to frequently replace special fixtures for different sizes, improving the versatility of the equipment. 4. The clamping part can be hidden in the commutation groove of the clamping table in the non-working state. This design effectively saves the equipment occupation space and makes the equipment structure more compact; at the same time, it reduces the risk of interference between components, especially suitable for narrow machining environments, improving the space utilization rate and the overall operation efficiency of the equipment.

Detailed implementation manners

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0019] Refer to Figures 1-12As shown in the figure, the present invention provides a processing device for a metal seal, including a base 1, a clamping table 2 and multiple sets of clamping parts 5. The clamping table 2 is fixedly arranged on the base 1. Multiple U-shaped assembly grooves 103 are arranged on the outer circumference of the base 1. The base 1 is integrally fixedly installed in a set use area by passing bolts through the assembly grooves 103. A sleeve rod 3 for supporting the rotation of the clamping part 5 is arranged inside the clamping table 2. A transmission component 4 for supporting the sleeve rod 3 to drive the clamping part 5 to move radially along the clamping table 2 is arranged in the middle of the clamping table 2. By adjusting the radial positions of the sleeve rod 3 and the clamping part 5, the gathering degree of multiple sets of clamping parts 5 is changed, so as to adapt to the clamping and processing of ring seals 10 of different sizes; Specifically, the clamping part 5 includes a chuck 501 and a core rod 502. The chuck 501 includes an outer circumferential clamping plate 501a and an inner circumferential clamping plate 501b connected vertically. The outer circumferential clamping plate 501a is in a concave arc shape, and the inner circumferential clamping plate 501b is in an outward-expanded arc shape. The core rod 502 can rotate inside the sleeve rod 3. The clamping part 5 can rotate to switch the up and down positions of the outer circumferential clamping plate 501a and the inner circumferential clamping plate 501b, so as to clamp the inner circumference or the outer circumference of the ring seal 10. A reversing groove 201 for accommodating the chuck 501 to rotate supported by the core rod 502 is arranged on the clamping table 2. When the clamping part 5 rotates to the horizontal state, it can be hidden in the reversing groove 201 of the clamping table 2. At this time, the clamping of the clamping part 5 on the ring seal 10 and the hindrance to horizontal movement are released, which is convenient for taking and placing the ring seal 10.

[0020] As an optional implementation manner, a clamping motor 101 is fixed on one side of the top of the base 1, and a rotating table 102 is fixed on the top of the base 1. A synchronous ring 6 is arranged between the base 1 and the clamping table 2. The rotating table 102 is used to support the rotation of the synchronous ring 6. Specifically, a synchronous gear ring 601 and a rotating convex edge 602 are coaxially arranged on the top side of the synchronous ring 6. A driving gear 101a meshing with the synchronous gear ring 601 is arranged at the output end of the clamping motor 101. The clamping motor 101 drives the synchronous gear ring 601 through the driving gear 101a to drive the synchronous ring 6 to rotate. The rotating convex edge 602 of the synchronous ring 6 and the rotating table 102 of the base 1 are rotationally matched through a thrust bearing to ensure that the synchronous ring 6 can rotate smoothly supported by the base 1; In addition, an installation groove 202 for accommodating the transmission component 4 is also arranged on the clamping table 2. The transmission component 4 includes an installation frame 401 with a rectangular frame structure and a transmission gear 402. The installation frame 401 is fixed inside the installation groove 202. The transmission gear 402 is rotatably arranged in the installation frame 401. Multiple sets of transmission gears 402 are all meshed with the synchronous gear ring 601, so as to drive multiple sets of transmission gears 402 to rotate synchronously through the rotation of the synchronous gear ring 601, and realize the synchronous transmission process; The sleeve rod 3 passes through the central inner hole of the mounting frame 401, and the sleeve rod 3 is in clearance fit with the mounting frame 401. A plurality of constraint blocks 401a are fixed around the inner hole inside the mounting frame 401. A plurality of constraint grooves 301 are provided on the outer circumference of the sleeve rod 3 corresponding to the constraint blocks 401a. The constraint blocks 401a and the constraint grooves 301 are in sliding fit along the radial direction of the clamping table 2, ensuring that the transmission assembly 4 can support the sleeve rod 3 to slide radially. The transmission frame is used to support the sleeve rod 3 to drive the clamping part 5 as a whole to slide radially to realize the gathering and expansion of the chuck 501, so as to adjust the position of the chuck 501 to adapt to ring seals 10 of different sizes, and to correspondingly adjust the position of the chuck 501 when adjusting the clamping of the inner and outer walls. A coolant storage and collection cover (not shown in the figure) is provided between the clamping table 2 and the adjusting ring 7, which can collect and store the metal chips and cooling water generated during the clamping and machining of the inner and outer walls of the ring seal 10, so as to reduce the influence of the cutting chips on the operation of the lower gear components. At the same time, a disc-shaped magnetic adsorption component is also provided at the center of the clamping table 2 to assist in collecting the iron chips generated during machining, further reducing the subsequent cleaning difficulty and improving the operation protection of the lower moving components; The sleeve rod 3 passes through the transmission gear 402 along its length direction, and the sleeve rod 3 is in threaded fit with the transmission gear 402. Through the sliding fit between the external constraint groove 301 of the sleeve rod 3 and the internal constraint block 401a of the transmission frame, the rotation of the transmission gear 402 is utilized to drive the sleeve rod 3 to slide radially along the clamping table 2 to realize the position adjustment of the chuck 501; It further includes a control unit 8. The control unit 8 is a cylinder or an electric push rod, preferably a cylinder, which uses an air pump as a power source and does not require the use of electricity, reducing the risk of electric leakage when using coolant during the processing, making it safer to use. A vertically extending fixed column 204 is fixedly arranged on the top side of the clamping table 2. A fixed ear 801 is arranged at the fixed end of the control unit 8. The fixed ear 801 and the fixed column 204 are hinged to form a hinge support. The fixed column 204 is used to support the rotation of the fixed ear 801 of the control unit 8. It further includes an adjusting ring 7 and an extension frame 9. A guiding groove 203 with a groove structure is arranged on the outer circumference of the clamping table 2. The adjusting ring 7 can rotate in the guiding groove 203 outside the clamping table 2. The traction frame 802 at the telescopic end of the control unit 8 is hinged to the connecting hole 702 of the adjusting ring 7. The control unit 8 forms an inclined extending driving execution component, which is used to pull the adjusting ring 7 to rotate coaxially outside the clamping table 2 through the control unit 8. The extension frame 9 includes a support plate 901 fixed to the top side of the clamping table 2. The support plate 901 extends radially along the clamping table 2. The outer end of the support plate 901 is bent downward to form a support ear 902 for the core rod 502 to pass through. A rotating sleeve 903 sleeved on the outside of the core rod 502 is rotatably arranged inside the support ear 902. The rotating sleeve 903 and the core rod 502 are in clearance fit to ensure that the core rod 502 can slide along its length direction inside the rotating sleeve 903. A support groove 502a is arranged on the core rod 502. The support groove 502a is a through groove structure extending along the length direction of the core rod 502. A support block 903a that is slidably matched with the support groove 502a is fixed inside the rotating sleeve 903. A positioning gear ring 701 is arranged on the outer circumference of the adjusting ring 7. A positioning gear 904 that meshes with the positioning gear ring 701 is fixed on the end face of the rotating sleeve 903.

[0021] The processing equipment for the metal seal described in this application, based on the improvement of the traditional processing process, arranges a synchronous ring 6 and a positioning gear ring 701 between the base 1 and the clamping table 2, and uses the clamping motor 101 to drive the synchronous gear ring 601 to mesh with multiple groups of transmission gears 402, so as to realize the radial synchronous gathering and expansion of multiple groups of clamping parts 5, complete the clamping of ring seals 10 with different diameters, and ensure that the forces on each clamping point are balanced. Combining the threaded fit between the sleeve rod 3 and the transmission gear 402 and the sliding guidance between the restraint block 401a and the restraint groove 301, the chuck 501 can move smoothly in the radial direction without replacing the fixture, thus improving the versatility and accuracy of the equipment; a reversing groove 201 and a rotatable core rod 502 are arranged on the clamping table 2, so that the outer circumferential clamping plate 501a and the inner circumferential clamping plate 501b can be rotated to switch to the upper and lower positions, and are hidden in the reversing groove 201 in the horizontal state to avoid interference with the workpiece or the tool. Therefore, the switching of the inner and outer wall clamping modes can be completed without disassembling the workpiece or moving the tool upward, greatly shortening the switching time; the adjusting ring 7 and the extension frame 9 cooperate with each other. The control part 8 of the cylinder or the electric push rod drives the telescopic end to pull the adjusting ring 7 to rotate, thereby driving the rotating sleeve 903 at the end of the extension frame 9 to move synchronously, realizing the rapid switching of the chuck 501 between the hidden and working positions and providing enough installation and operation space. In addition, a coolant storage and collection cover is added between the clamping table 2 and the adjusting ring 7 to centrally collect the metal chips and cooling water generated during the processing, and a disc-shaped magnetic adsorption component is configured at the center of the clamping table 2 to assist in adsorbing iron chips, thereby effectively protecting the transmission structure below and simplifying the daily cleaning and maintenance.

[0022] The processing equipment for the metal seal described in this application has a compact overall structure. Through the hidden design, it saves vertical space and reduces the probability of component interference. It is particularly suitable for machine tool environments with limited space, realizes continuous internal and external wall processing of metal ring seals 10 with different sizes and wall thicknesses on the same equipment without repeatedly disassembling or replacing special fixtures, effectively reduces the frequency of manual intervention, reduces the equipment downtime, significantly improves the production efficiency and processing quality, and enhances the versatility and reliability of the equipment.

[0023] The present invention also provides a processing method for a metal seal, comprising the following steps: S1: Fix the base 1 to the processing equipment through the assembly groove 103 by bolts, such as fixing it on the workbench mounting base surface of a lathe, and then place the ring seal 10 between multiple groups of clamping parts 5 on the clamping table 2; S2: According to the situation of the part to be processed on the annular seal 10, the telescopic end of the control unit 8 contracts, thereby pulling the adjustment ring 7 to rotate. The positioning gear ring 701 of the adjustment ring 7 drives the positioning gears 904 of multiple extension frames 9 to rotate synchronously, so as to rotate the core rod 502 through the support blocks 903a inside multiple rotating sleeves 903. According to the required clamping position of the annular seal 10, the outer circumferential clamping plate 501a or the inner circumferential clamping plate 501b of the chuck 501 is rotated to the upward state, completing the rotation and preliminary clamping action of the chuck 501; S3: Start the clamping motor 101. The driving gear 101a at the output end of the clamping motor 101 drives the synchronous gear ring 601 of the synchronous ring 6 to rotate. Since the synchronous gear ring 601 is engaged with multiple transmission gears 402, multiple transmission gears 402 are driven to rotate synchronously. The transmission gears 402 rotate smoothly within the transmission frame. Due to the threaded engagement between the transmission gears 402 and the sleeve rod 3, and the sliding fit between the constraint block 401a and the constraint groove 301, the constraint block 401a is used to slide-guide the sleeve rod 3, restricting the sleeve rod 3 to only translate and slide radially along the clamping table 2, so that the sleeve rod 3 drives the clamping part 5 to move radially along the clamping table 2, realizing the gathering or outward expansion of the chuck 501, clamping and fixing the annular seal 10, and completing the clamping and supporting action of the chuck 501 on the annular seal 10; S4: When it is necessary to switch the clamping for machining the inner circumference or outer circumference of the annular seal 10, first start the clamping motor 101 to release the clamping state of multiple clamping parts 5 on the annular seal 10. Specifically, if the annular seal 10 is in the state of clamping the outer circle, drive multiple chucks 501 to expand outward; if the annular seal 10 is in the state of clamping the inner circle, drive multiple chucks 501 to gather inward, that is, move the chucks 501 radially to separate them from the annular seal 10. Then start the control unit 8, and the traction frame 802 driven by the control unit 8 pulls the adjustment ring 7 to rotate. Thus, the positioning gear 904 on the end face of the rotating sleeve 903 is driven to rotate by the positioning gear ring 701 of the adjustment ring 7, so that the support blocks 903a inside multiple rotating sleeves 903 support the core rod 502 to drive the chuck 501 to rotate, so as to synchronously drive the rotation of the chucks 501 of multiple clamping parts 5; Drive the core rod 502 of the clamping part 5 to drive the chuck 501 to rotate to the horizontal state within the sleeve rod 3, so that the chuck 501 is hidden in the commutation groove 201 of the clamping table 2. At this time, when the whole chuck 501 moves radially along the clamping table 2 within the commutation groove 201, it is ensured that the annular seal 10 placed above will not hinder the sliding movement of the chuck 501, that is, there is no need to remove workpieces such as the annular seal 10 for the position switching process of the inner and outer wall fixtures; After the rotation and hiding action of the chuck 501 in the commutation groove 201 is completed, the clamping motor 101 is started again. The driving gear 101a of the clamping motor 101 drives the synchronous gear ring 601 of the synchronous ring 6 to rotate, and the synchronous gear ring 601 drives the transmission gears 402 of multiple groups of transmission components 4 to rotate. By using the threaded engagement between the transmission gear 402 and the sleeve rod 3, and combining with the sliding guiding effect of the constraint block 401a on the constraint groove 301, the transmission component 4 drives the sleeve rod 3 to drive the clamping part 5 to move radially along the clamping table 2, changing the radial position of the clamping part 5, so as to adjust the relative position between the chuck 501 and the annular seal 10; After moving into place, the control part 8 pulls the adjusting ring 7 to rotate again, thereby driving the core rod 502 to support one end of the annular seal 10 that needs to be clamped by the chuck 501 to rotate and extend out of the commutation groove 201, so that one set of clamping plates rotates and switches to the upward working position. Again, through the transmission component 4, the chucks 501 of multiple groups of clamping parts 5 are gathered or expanded, realizing the inner and outer wall switching and clamping action of the annular seal 10 without taking out the workpiece.

[0024] By driving the clamping part 5 to rotate and move horizontally in the commutation groove 201, the up and down position switching of the chuck 501 can be realized, so as to quickly meet the replacement action of the inner circle fixture and the outer circle fixture, avoiding the tediousness of the traditional equipment that requires manual workpiece taking and then adjusting the fixture position, shortening the clamping position switching process time when the inner and outer circles of the annular seal 10 are processed in sequence, and improving the production efficiency; At the same time, when disassembling and assembling the workpiece, the multiple groups of clamping parts 5 are directly rotated to the horizontal state quickly to realize the hiding action of the fixture in the commutation groove 201, without moving up the processing tool to leave space for the workpiece to be taken out upward from the fixture, simplifying the operation process of taking and placing the workpiece in the processing process and making it more convenient to use; In addition, by rotating and switching the inner and outer circumferential clamping plates 501a of the clamping part 5 and adjusting the radial position, the processing requirements of annular seals 10 with different sizes and specifications can be quickly adapted, without frequently replacing special fixtures for different sizes, improving the versatility of the equipment; The clamping part 5 can be hidden in the commutation groove 201 of the clamping table 2 in the non-working state. This design effectively saves the equipment occupation space and makes the equipment structure more compact; at the same time, it reduces the risk of interference between components, especially suitable for narrow processing environments, improving the space utilization rate and the overall operation efficiency of the equipment; For metal annular seals 10 of different materials (such as stainless steel, copper alloy, etc.) and different wall thicknesses, the present invention can stably clamp and process annular workpieces of different sizes by switching the inner and outer wall clamping methods. In particular, for thin-walled annular seals 10, the inner and outer walls are alternately processed multiple times by the present equipment during the processing. Because of the thin wall thickness of the structure, the inner and outer walls of traditional processing equipment are processed at one time, and the same side is ground for a long time, which easily leads to high-temperature deformation of the workpiece. The present invention relies on the ability to quickly adjust the inner and outer clamping positions to alternately grind the inner and outer sides, and is particularly suitable for the clamping processing of such annular seals 10 with low structural strength.

[0025] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
