[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 3 The utility model provides an embodiment: a processing fixture for rapid heat treatment of edge rings, including a ring body 1, a gasket ring 2 is fixedly connected to the inner side of the ring body 1, and the gasket ring 2 is designed to be installed at the bottom of the groove of the ring body 1, and plays a role of bottom support for the ring body 1 during processing, and one side of the gasket ring 2 is in contact with the groove plane of the ring body 1, and the thickness of the gasket ring 2 is 0.2-0.8mm greater than the groove depth of the ring body 1, and the diameter of the gasket ring 2 is 0.1-0.7mm smaller than the inner diameter of the groove of the ring body 1. The rear end of the ring body 1 is fixedly connected to a base 3, and the rear end of the gasket ring 2 is fixedly connected to the front end of the base 3. The base 3 and the gasket ring 2 are bonded by paraffin wax. A plurality of support rings 4 are fixedly connected to the outer side of the front end of the base 3, and the rear ends of the plurality of support rings 4 are fixedly connected to the front end of the ring body 1. These support rings 4 are distributed around the outer side of the ring body 1 to support the outer periphery of the ring body 1, so as to avoid the ring body 1 from breaking when processing the groove of the ring body 1.

[0027] A plurality of support rings 4 are circumferentially distributed at the front end of the base 3. The inner wall of the support ring 4 is threadedly connected with a fixing assembly for maintaining the stability of the clamp. The fixing assembly includes a plurality of screws 6. The outer threads of the screws 6 are connected to the inner wall of the support ring 4. The screws 6 are circumferentially distributed at the inner wall of the support ring 4. The outer threads of the screws 6 are connected to the inner wall of the base 3. The plurality of screws 6 are circumferentially distributed at the inner wall of the base 3. Each support ring 4 is designed with 2-4 holes and connected to the base 3 through the screws 6. The inner diameter of the support ring 4 is 0.1-0.6 mm larger than the outer diameter of the ring body 1, and the step outer diameter of the base 3 is 0.1-0.6 mm smaller than the inner diameter of the support ring 4. The front end of the base 3 is provided with a plurality of threaded holes 5. The plurality of screws 6 are circumferentially distributed at the front end of the base 3. The base 3 is the main bearing tool and is designed with 3-9 threaded holes 7. It is connected to the machine tool workbench through the screws 6. The front end of the base 3 is provided with a threaded hole 7. A grindstone can be installed in the threaded hole 7 here for the grinding wheel used in the grinding process. This design allows the tool to be trimmed during the machining process, avoiding the need for secondary clamping after removing the tooling during the machining process, thereby further ensuring the machining accuracy of the ring body 1.

[0028] During assembly, the gasket 2 is first installed at the bottom of the groove of the ring body 1 and bonded with paraffin. Then, the gasket 2 and the ring body 1 are installed on the base 3, and the base 3 is bonded to the bottom surface of the gasket 2 with paraffin. Finally, multiple support rings 4 are connected to the base 3 with screws 6, and the support ring 4 surrounds the ring body 1 for one week, ensuring the stability of the entire structure and the accuracy of the processing process.

[0029] Working principle: First, the gasket 2 is installed at the bottom of the groove of the ring body 1, and paraffin is used for bonding to ensure that one side of the gasket 2 fits tightly with the groove plane of the ring body 1. This step is to provide bottom support for the ring body 1 during processing to prevent the ring body 1 from breaking due to being too thin. Then, the gasket 2 and the ring body 1 are installed as a whole on the base 3, and paraffin is used again to bond the bottom surface of the gasket 2 to the base 3. As the main load-bearing tool, the base 3 is connected to the machine tool workbench by screws 6, providing stability for the entire fixture.

[0030] Subsequently, a plurality of support rings 4 are fixed to the outside of the front end of the base 3. These support rings 4 are connected to the base 3 by screws 6 and surround the outside of the ring body 1. The function of the support ring 4 is to provide additional support to the periphery of the ring body 1 when processing the groove of the ring body 1 to prevent the ring body 1 from breaking due to pressure. Each support ring 4 is designed with 2-4 holes to ensure its stable connection with the base 3. In addition, the inner diameter of the support ring 4 is slightly larger than the outer diameter of the ring body 1, and the outer diameter of the step of the base 3 is slightly smaller than the inner diameter of the support ring 4. Such a size design allows precise matching between components.

[0031] Finally, the front end of the base 3 is provided with a plurality of threaded holes 7, which can be used to install a grindstone so as to sharpen the grinding wheel used in the processing process. This design reduces the need for secondary clamping after removing the tooling during the processing process, thereby improving the processing accuracy of the ring body 1. Through this series of assembly and processing steps, the fixture can effectively improve the processing efficiency and product quality of the edge ring during the heat treatment process, while also ensuring the safety and convenience of operation.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
