Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] See Figure 1-4 This embodiment relates to a positioning fixture for processing ceramic sealing rings, including a clamping assembly 1. The clamping assembly 1 includes a base 11 and a fixed seat 12 that is detachably connected to a mounting groove 111 opened on the base 11. A second mounting groove 121 is opened in the fixed seat 12, and a connecting rod 122 is provided in the second mounting groove 121. A bushing 13 is sleeved on the rod body of the connecting rod 122, and a top cover 14 is fastened to the top of the rod body above the bushing 13.

[0019] Specifically in this embodiment, such as Figure 1 The overall structural arrangement of the frame 3, the fixed plate 2 on it, and the clamping assembly 1 on it shown can be referred to in actual use. Figure 2-4As shown, the clamping assembly 1 can be installed and fixed at the processing position through a plurality of mounting holes 110 circumferentially opened on the chassis 11. Furthermore, the size of the second mounting groove 121 in the fixing seat 12 and the structure of the bushing 13 with corresponding wall thickness can be set according to the specific specifications of the ceramic seal. The fixing seat 12 can be rotatably installed on the threaded rod 112 provided in the mounting groove 111 on the chassis 11 through the threaded hole 120 opened at the bottom of its seat body, realizing the detachable connection process of the fixing seat 12 to the chassis 11. Subsequently, when the fixing seat 12 is on the second mounting groove 111 of the chassis 11... After tightening in the mounting groove 121, the bushing 13 is fitted onto the body of the connecting rod 122. Simultaneously, the outer wall of the bushing 13, with its appropriate wall thickness, passes through the inner hole in the center of the ceramic sealing ring for fitting the ceramic sealing ring. The ceramic sealing ring can slide along the outer wall of the bushing 13 and fit into the second mounting groove 121, conforming to its bottom wall. Furthermore, the bushing 13 fitted onto the connecting rod 122 and the ceramic sealing ring fitted onto the bushing 13 can be connected using either a clearance fit or an interference fit, depending on the clamping requirements. The clearance fit method requires that, while ensuring that the ceramic sealing ring does not wobble or shift, it allows for easy fitting, disassembly, and switching of the connecting rod 122 and bushing 13 according to processing requirements. Simultaneously, the ceramic sealing ring within the second mounting groove 121 can rotate in the corresponding direction around the connecting rod 122 and bushing 13. The length of the bushing 13 can be set to match the specific thickness of the connecting rod 122 and the ceramic sealing ring. Combined with the detachable top cover 14 with a plug-in structure at the top of the connecting rod 122, it allows for... The bushing 13 on the connecting rod 122 and the ceramic sealing ring fitted on it are positioned. The insertion structure includes a slot 123 opened at the top of the connecting rod 122 and an annular groove 124 opened around the inside of the slot 123. The top cover 14 is provided with a plug rod 141 inserted into the slot 123 and a protruding ring 142 around the outside of the plug rod 141 for engaging with the annular groove 124. Thus, combined with the fastening process of the top cover 14 at the top of the connecting rod 122, the position of the bushing 13 and the ceramic sealing ring fitted on it can be conveniently positioned and disassembled.The interference fit ensures the positional stability of the bushing 13 and its ceramic sealing ring on the connecting rod 122, preventing rotation during subsequent processing. This allows for flexible adjustment of the clamping structure according to different processing requirements. The lengths of the bushing 13 and the connecting rod 122 can be set to be greater than the thickness of the ceramic sealing ring. The interference fit prevents positional shift of the bushing 13 and its ceramic sealing ring on the connecting rod 122. Combined with the detachable connection of the fixing seat 12 to the mounting groove 111 on the chassis 11, this facilitates the switching of the overall structure of the fixing seat 12 and its ceramic sealing ring in the second mounting groove 121. It also facilitates the installation and removal of the top cover 14 on the connecting rod 122. The overall structure of this positioning fixture for processing ceramic sealing rings features a slightly larger initial diameter and depth of the mounting groove 111 on the base 11 in the clamping assembly 1. Simultaneously, the diameter and depth of the second mounting groove 121 within the fixed seat 12, the specific lengths of the connecting rod 122 and the bushing 13, and the specific wall thickness of the bushing 13 surrounding the connecting rod 122 can be configured with multiple sets of matching structures for the fixed seats 12 and bushings 13 according to the different specifications of the batch of ceramic sealing rings to be processed. Furthermore, during configuration, appropriate gaps are maintained between the mounting groove 111 on the base 11 and the outer wall of the fixed seat 12, and between the second mounting groove 121 on the fixed seat 12 and the outer edge of the ceramic sealing ring. This allows for the detachable connection of the fixed seat 12 to the base 11. The process of replacing and detachably connecting and replacing the bushing 13 on the connecting rod 122 allows for the installation, fixing, disassembly, and replacement of the fixed seat 12 and bushing 13 on the chassis 11 according to the corresponding structural settings for ceramic sealing rings of different specifications. This provides high flexibility and applicability. Furthermore, this clamping assembly 1, by fixing the ceramic sealing ring in position through the fixed seat 12 and the bushing 13 on the connecting rod 122, ensures uniform force distribution on the ceramic sealing ring during clamping and processing compared to traditional gripper structures. It facilitates adjustment of the clamping structure while providing high clamping stability, effectively reducing the risk of edge chipping of the ceramic sealing ring, ensuring the overall structural stability of the ceramic sealing ring during clamping and processing, improving processing quality, and saving on operating costs.

[0020] A second sleeve 15 is also fitted between the connecting rod 122 and the bushing 13. The connecting rod 122 has a prism-shaped structure. The inner and outer side walls of the second sleeve 15 are respectively provided with a prism groove 151 structure to fit the prism and a cylindrical structure to fit the inner wall of the bushing 13. The second sleeve 15 can be fitted between the connecting rod 122 and the bushing 13 in a split structure or as an integral part of the inner wall of the bushing 13. The integral structure formed by the second sleeve 15 fitted on the inner wall of the bushing 13 and the bushing 13 can be found in [reference needed]. Figure 3 As shown, when the ceramic sealing ring and bushing 13 are connected by either clearance or interference fit according to processing requirements, the top cover 14 on the connecting rod 122 limits the position of the top of the second sleeve 15, enabling the ceramic sealing ring to rotate and be fixed in position on the bushing 13 within the second mounting groove 121 of the fixed seat 12. Furthermore, when the bushing 13 and ceramic sealing ring are connected by an interference fit, the connection structure between the bushing 13 and the connecting rod 122 via the second sleeve 15 facilitates the disassembly and replacement of the ceramic sealing ring within the second mounting groove 121 of the fixed seat 12. Additionally, the second sleeve 15 can also be... Figure 2 or Figure 4 The connecting rod 122 and the bushing 13 are designed as separate structures. The second sleeve 15 is fitted between the connecting rod 122 and the bushing 13 through the grooves 151 and cylindrical structures on the inner and outer sides, respectively. At this time, the second sleeve 15, which is fitted on the prismatic connecting rod 122 through the grooves 151, is fixed in position and cannot rotate. At the same time, the bushing 13 fitted on the second sleeve 15 and the ceramic sealing ring fitted on it are adjusted accordingly to achieve the connection process of individual or synchronous rotation of the bushing 13 and the ceramic sealing ring of the second sleeve 15 as well as overall fixation. This further improves the detachability and disassembly flexibility of the overall structure of this clamping assembly 1, and can also effectively reduce the further wear on the surface of the ceramic sealing ring, meeting different clamping requirements.

[0021] like Figure 2-4As shown, the clamping assembly 1 also includes a connecting seat 16 slidably disposed on a connecting rod 122 located in a second mounting groove 121 on the fixed base 12. A third mounting groove 161 is provided in the connecting seat 16, and a through hole 162 for sliding of the second sleeve 15 is provided at the bottom of the third mounting groove 161. The second sleeve 15 extends redundantly at both the upper and lower ends of the bushing 13. The bushing 13 is placed in the third mounting groove 161 above the through hole 162, and a locking element 152 is rotatably disposed around the second sleeve 15 above the bushing 13. Specifically, in use, the fixed base 12... The connecting seat 16 can also be structurally modified. Specifically, the second mounting groove 121 on the fixed seat 12 is adapted to the structure of the connecting seat 16, and the third mounting groove 161 on the connecting seat 16 is set in diameter and depth according to the specific specifications of the ceramic sealing ring. During installation, the connecting seat 16 can pass through the connecting rod 122 of the fixed seat 12 through the through hole 162 on its seat body. At the same time, it can slide and be positioned on the second sleeve 15 sleeved around the connecting rod 122. The bushing 13 on the second sleeve 15 can be placed above the through hole 162. The ceramic sealing ring can be fitted onto the bushing 13 through the third mounting groove 161 on the connecting seat 16. Combined with the adjustment process of the locking member 152 on the second sleeve 15, which is connected by bolts, through a threaded structure, the position of the bushing 13 can be limited and locked. At this time, the top cover 14, which is fastened to the top of the connecting rod 122, can limit the position of the second sleeve 15. Therefore, after the ceramic sealing ring in the third mounting groove 161 on the connecting seat 16 is processed, the top cover 14 can be removed from the top of the connecting rod 122 beforehand, combined with manual operation. Under the application of external force during the upward lifting process of the connecting seat 16 along the chassis 11, the second sleeve 15, bushing 13, and ceramic sealing ring can be separated and removed from the second mounting groove 121 and its internal connecting rod 122 of the fixed seat 12, driven by the connecting seat 16. At the same time, another ceramic sealing ring is pre-installed on the other connecting seat 16 in the third mounting groove 161 through another set of second sleeve 15, bushing 13, and locking member 152. Combined with the top cover 14, the structure of another set of ceramic sealing rings of the same or different specifications on this set of fixed seats 12 is switched and subsequent processing is carried out. The addition of the connecting seat 16 structure can further improve the convenience and efficiency of disassembling and switching ceramic sealing rings in batches, and further improve the functional versatility and usage flexibility of this clamping assembly 1.

[0022] It also includes a fixed plate 2, a frame 3 for mounting the fixed plate 2, and a mounting bracket 4 mounted on the frame 3 above the fixed plate 2. The clamping assembly 1 is mounted on the fixed plate 2 via a chassis 11 and multiple sets are arranged around the fixed plate 2. The fixed plate 2 is rotatably mounted on the frame 3 via a drive component 5 mounted below the frame 3. The drive component 5 includes a first drive motor 51 and a reducer 52 connected to the first drive motor 51 and the fixed plate 2 respectively. A positioning plate 53 is mounted on one end of the reducer 52 and connected to the first drive component 5. The frame 3, located on one side of the positioning plate 53, is equipped with sensors 54 for positioning detection of multiple sets of positioning rods 531 arranged around the positioning plate 53, corresponding to the positions of multiple sets of clamping assemblies 1 on the fixed plate 2. Specifically, from Figure 1 and Figure 5 As can be seen, in actual use, the mounting bracket 4 installed on the frame 3 can be used to install and fix the corresponding processing equipment above the fixed plate 2 according to the processing requirements. Combined with the circumferential installation process of multiple clamping components 1 at the corresponding positions of the fixed plate 2, the first driving component 5 in the driving component 5 drives the reducer 52 and the fixed plate 2 connected to it to rotate on the frame 3 through the synchronous belt drive. At the same time, under the drive of the first driving motor 51, the positioning plate 53 installed on the reducer 52 rotates synchronously, and drives the multiple positioning rods 531 installed on it, which are corresponding to the positions of the multiple clamping components 1 on the fixed plate 2, to rotate synchronously. During the process, the positioning rods 531 are detected by the sensor 54 set on one side of the positioning plate 53. Combined with the operation control of the controller installed on the frame 3, the rotation angle of the fixed plate 2 and the switching process of the multiple clamping components 1 at the corresponding positions are realized. This further improves the functional diversity of this positioning fixture for ceramic sealing ring processing, can meet the processing requirements in different usage environments, further improves processing efficiency, and has high applicability and practicality.

[0023] The frame 3 located below the drive component 5 is also equipped with a second connecting seat 31, and a third connecting seat 32 is slidably disposed on the second connecting seat 31. The drive component 5 is mounted on the third connecting seat 32 and is driven to move up and down by a cylinder 310 connected to the third connecting seat 32 and mounted on the second connecting seat 31. Figure 5 As shown, the drive component 5 installed on the third connecting seat 32 can move up and down on the multiple sets of slide rods 311 provided on the second connecting seat 31 under the push of the cylinder 310, and at the same time drive the fixed plate 2 to move up and down on the frame 3. Thus, the height of the fixed plate 2 and the clamping component 1 on it can be adjusted according to different processing requirements, thereby further improving the functional diversity, usage flexibility and applicability of this positioning fixture for ceramic sealing ring processing.
