Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal seal production and processing equipment, in particular to a metal seal processing equipment and method. BACKGROUND

[0002] Metal seals are mostly thin-walled ring structures, which function to build a tight sealing interface between mechanical components, effectively prevent fluid medium such as liquid and gas from leaking, ensure stable system pressure, and avoid the intrusion of external dust, moisture and other impurities. In the existing field of metal seal processing, when processing the inner and outer circumferential surfaces of the ring seal, a split type clamping tool and a manual switching operation mode are generally used. Specifically, the traditional processing equipment is mostly equipped with single-function inner or outer clamps. When switching the inner and outer walls of the ring seal for processing, the operator must first stop the machine, loosen the clamp, completely remove the workpiece from the clamp, remove the position obstruction of the workpiece to the clamp, then replace the appropriate inner or outer clamp, and reposition and clamp the workpiece. Since such processing equipment involves frequent manual loading and unloading and workpiece removal and disassembly, the production efficiency is significantly reduced, the single switching process takes a long time, and since the clamp height is fixed, the upper processing tool needs to be moved upward to create space for the workpiece to be removed from the clamp, which aggravates the complexity of disassembling and replacing the workpiece in the compact internal processing machine tool, making it inconvenient to use. SUMMARY

A cooling liquid storage cover (not shown in the figure) is arranged 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 processing 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 gear parts below. At the same time, the center of the clamping table 2 is also provided with a disc-shaped magnetic adsorption part, which is used to assist in collecting the iron chips generated during processing, further reducing the difficulty of subsequent cleaning, and improving the operation protection of the movable parts below.

[0048] The sleeve rod 3 penetrates the transmission gear 402 along the 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 sleeve rod 3 is driven to slide in the radial direction of the clamping table 2 by the rotation of the transmission gear 402, so as to realize the position adjustment of the chuck 501.

[0050] The machining equipment of the metal seal described in the application is based on the improvement of the traditional machining process, through arranging the synchronous ring 6 and the positioning gear ring 701 between the base 1 and the clamping table 2, and utilizing the clamping motor 101 to drive the synchronous gear ring 601 to mesh with the multiple sets of transmission gears 402, the radial synchronous gathering and expansion of the multiple sets of clamping parts 5 are realized, so as to complete the clamping of the circular ring seal 10 with different diameters, and ensure that the forces of each clamping point are balanced, and through the threaded cooperation of the sleeve rod 3 and the transmission gear 402 and the sliding guidance of the constraint block 401a and the constraint groove 301, the stable movement of the chuck 501 in the radial direction can be realized without replacing the clamp, so that the universality and precision of the equipment are improved; the reversing groove 201 and the 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 switched to the upper and lower positions by rotating and hidden in the reversing groove 201 in the horizontal state to avoid interference with the workpiece or the tool, so that the switching of the inner and outer wall clamping modes can be completed without disassembling the workpiece or moving the tool upward, and the switching time is greatly shortened; the adjusting ring 7 cooperates with the extension frame 9, the control part 8 of the air cylinder or the electric push rod drives the telescopic end to pull the adjusting ring 7 to rotate, so that the rotating sleeve 903 at the end of the extension frame 9 is synchronously driven to move, the chuck 501 is quickly switched between the hidden and working positions, and sufficient installation and operation space is provided. In addition, the cooling liquid storage and storage cover is additionally arranged between the clamping table 2 and the adjusting ring 7, which is used for collecting the metal chips and cooling water generated in the machining process, and the disc-shaped magnetic adsorption part is arranged at the center of the clamping table 2 to assist the adsorption of iron chips, so that the lower transmission structure is effectively protected and the daily cleaning and maintenance is simplified.

[0051] The machining equipment of the metal seal described in the application is compact in overall structure, saves vertical space and reduces the probability of component interference through hidden design, is particularly suitable for machine tool environments with limited space, realizes the continuous inner and outer wall machining of metal circular ring seals 10 with different sizes and wall thicknesses on the same equipment without repeated disassembly or replacement of special clamps, effectively reduces the frequency of manual intervention, reduces the equipment downtime, significantly improves the production efficiency and machining quality, and enhances the universality and reliability of the equipment.

[0052] The application also provides a machining method of a metal seal, comprising the following steps:

[0053] S1: the base 1 is fixed to the machining equipment through the assembly groove 103 by means of bolts, such as being fixed to the workbench mounting surface of a lathe, and then the circular ring seal 10 is placed between the multiple sets of clamping parts 5 of the clamping table 2;

[0054] S2: Based on the condition of the part to be processed of the annular seal 10, the telescopic end of the control unit 8 is contracted, thereby pulling the adjusting ring 7 to rotate. The positioning gear ring 701 of the adjusting ring 7 drives the positioning gears 904 of multiple extension frames 9 to rotate synchronously. Thus, the core rod 502 is rotated through the support block 903a inside the 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 position, completing the rotational pre-clamping action of the chuck 501.

[0055] S3: Start the clamping motor 101. The drive gear 101a at the output end of the clamping motor 101 drives the synchronous gear ring 601 of the synchronous ring 6 to rotate. The synchronous gear ring 601 maintains meshing with multiple sets of transmission gears 402, thereby driving the multiple sets of transmission gears 402 to rotate synchronously. The transmission gears 402 rotate smoothly in the transmission frame. Due to the threaded engagement between the transmission gears 402 and the sleeve rod 3, and the sliding engagement between the constraint block 401a and the constraint groove 301, the constraint block 401a guides the sleeve rod 3 to slide, restricting the sleeve rod 3 to slide only radially along the clamping table 2. This causes the sleeve rod 3 to drive the clamping part 5 to move radially along the clamping table 2, realizing the chuck 501 to converge or expand outward, clamping and fixing the annular seal 10, and completing the clamping and supporting action of the chuck 501 on the annular seal 10.

[0056] S4: If it is necessary to switch the clamping process of the inner circumference or the outer circumference of the annular seal 10, first start the clamping motor 101 to release the clamping state of the multiple clamping parts 5 on the annular seal 10. Specifically, if the annular seal 10 is clamped on the outer circle, drive the multiple clamps 501 to expand outward. If the annular seal 10 is clamped on the inner circle, drive the multiple clamps 501 to converge inward, that is, move the clamps 501 radially to separate them from the annular seal 10. Then start the control unit 8, and drive the traction frame 802 to pull the adjusting ring 7 to rotate. Then, use the positioning gear ring 701 of the adjusting ring 7 to drive the positioning gear 904 on the end face of the rotating sleeve 903 to rotate. This causes the support block 903a inside the multiple rotating sleeves 903 to support the core rod 502 and drive the clamps 501 to rotate, so as to synchronously drive the clamps 501 of the multiple clamping parts 5 to rotate.

[0057] The core rod 502 of the clamping part 5 drives the chuck 501 to rotate to a horizontal state in the sleeve rod 3, so that the chuck 501 is hidden in the reversing groove 201 of the clamping table 2. At this time, the chuck 501 moves radially along the clamping table 2 in the reversing groove 201 to ensure that the ring seal 10 placed above will not obstruct the sliding movement of the chuck 501. That is, there is no need to remove the ring seal 10 and other workpieces to switch the position of the inner and outer wall clamps.

[0058] After the rotation hiding action of the clamping head 501 in the reversing groove 201 is completed, the clamping motor 101 is started again to drive the synchronous gear ring 6 to rotate through the driving gear 101a of the clamping motor 101, and the transmission gear 402 of the plurality of transmission assemblies 4 is driven to rotate through the synchronous gear ring 601, so as to drive the sleeve rod 3 to drive the clamping part 5 to move radially along the clamping table 2 through the cooperation of the transmission gear 402 and the thread of the sleeve rod 3, and the sliding guide action of the constraint block 401a to the constraint groove 301, so as to change the radial position of the clamping part 5, and adjust the relative position of the clamping head 501 and the circular ring seal 10.

[0059] After moving to the position, the control part 8 pulls the adjusting ring 7 to rotate again, and then drives the core rod 502 to support the clamping head 501 to rotate and extend out of the reversing groove 201 to clamp one end of the circular ring seal 10, so that one of the clamping plates rotates and switches to the upward working position, and the plurality of clamping parts 5 are gathered or expanded again through the transmission assembly 4, so that the inner and outer wall switching clamping action of the circular ring seal 10 is completed without taking out the workpiece.

[0060] By driving the clamping part 5 to rotate and move horizontally in the reversing groove 201, the up-down position switching of the clamping head 501 can be realized, so as to quickly meet the exchange action of the inner circle clamp and the outer circle clamp, avoid the complexity of manually adjusting the clamp position after taking out the workpiece in the traditional equipment, shorten the clamping position switching process time when the inner and outer circles of the circular ring seal 10 are processed in turn, and improve the production efficiency;

[0061] At the same time, when the workpiece is disassembled, the plurality of clamping parts 5 are quickly rotated to the horizontal state to realize the hiding action of the clamp in the reversing groove 201, without the need to move the machining tool upward to leave space for taking out the workpiece from the clamp, which simplifies the taking and placing operation process of the machining process and is more convenient to use;

[0062] In addition, through the rotation switching of the inner and outer circumferential clamping plates 501a of the clamping part 5 and the radial position adjustment, the machining demand of the circular ring seal 10 of different sizes can be quickly adapted, without the need to frequently replace special clamps for different sizes, and the versatility of the equipment is improved;

[0063] The clamping part 5 can be hidden in the reversing groove 201 of the clamping table 2 in the non-working state, which effectively saves the occupied space of the equipment, makes the equipment structure more compact, reduces the risk of interference between parts, is especially suitable for narrow machining environment, and improves the space utilization and overall operation efficiency of the equipment;

[0064] For the metal ring seal 10 of different materials (such as stainless steel, copper alloy, etc.) and different wall thickness, the present application can stably clamp and process ring workpieces of different sizes by switching the inner and outer wall clamping mode, especially for the thin-walled type ring seal 10, which is processed by the device for multiple alternating processing of the inner and outer walls during the processing process. Because the structure wall thickness is thin, the inner wall and the outer wall of the traditional processing equipment are processed at one time, and the same side is ground for a long time, which can easily cause the workpiece to be deformed at high temperature. The present application relies on the quick adjustment of the inner and outer clamping positions to alternately grind the inner and outer sides, and is especially suitable for clamping and processing of such ring seal 10 with low structural strength.

[0065] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
