[0002] Piston rings are metal rings used to fit inside the grooves of a piston. There are two types of piston rings: compression rings and oil rings. Compression rings are used to seal the combustible mixture in the combustion chamber; oil rings are used to scrape excess oil off the cylinder. Today, piston rings are widely used and have become an indispensable mechanical component. The piston ring manufacturing process involves many steps to produce a finished product, among which grinding is an essential process and a key step affecting the precision of the piston ring's forming. Existing technologies also offer various precision machining fixtures for piston rings.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0017] Examples, such as Figures 1-5As shown, a precision forming fixture for thin elliptical cylindrical piston rings includes a fixture body. The fixture body includes a stepped worktable, which is divided into a high platform 1 and a low platform 2 according to its height. The height design of the worktable makes the placement of equipment with different usage requirements more reasonable, especially improving the rationality of the equipment placement. In order to achieve precision machining of the workpiece, a lifting and grinding component 3 is provided on the upper rear side of the high platform 1, and a lifting and bearing component 4 is provided below the high platform 1 corresponding to the lifting and grinding component 3. The two work together to lift the position of the workpiece away from the transfer plate 14 to prevent damage to the equipment. On the other hand, the lifting and grinding component 3 can be used to complete the grinding and machining of the workpiece, improving the functionality of the equipment. An inner positioning component 5 is provided on the lower outer side of the lifting and grinding component 3, and a pushing mechanism 6 is provided on one side of the inner positioning component 5. A transverse slide 7 is provided on the low platform 2, and a transverse sliding mechanism is provided on the transverse slide 7. A transverse drive cylinder 9 is installed below the low-level platform 2, with its output end passing through the low-level platform 2 and connected to the outside of the transverse plate 8. A longitudinal slide bar 10 is installed above the transverse plate 8, and a longitudinal transfer plate 11 is installed above the longitudinal slide bar 10. A longitudinal drive cylinder 12 is installed on the transverse plate 8, with its output end connected to one side of the longitudinal transfer plate 11. A carrier frame 13 is installed on the longitudinal transfer plate 11, and a transfer plate 14 is installed above the carrier frame 13. Two transfer plates 14 are arranged side by side as a group. The gaps between the components are adapted to the specifications of the workpiece. It should be further explained that the operation of the transverse drive cylinder 9 controls the transverse movement of the equipment above the transverse transfer plate 8, especially enabling the transfer plate 14 to move and move the material. The extension and retraction of the longitudinal drive cylinder 12 controls the longitudinal movement of the longitudinal transfer plate 11 to ensure that the transfer plate 14 can be smoothly reset after outputting the material to one side, waiting for the next processing operation to proceed smoothly.An external positioning component 15 is installed above the moving frame. The cooperation between the internal positioning component 5 and the external positioning component 15 facilitates the positioning of the workpiece to be processed, reducing the possibility of displacement and ensuring the grinding effect to meet usage requirements. The specific working method is as follows: the workpiece to be processed is transported to the front of the pushing mechanism 6 by an external conveyor belt. Then, the forward and reverse moving component 16 is controlled to drive the material to move closer to the transfer plate 14. Finally, the transverse drive cylinder 9 is controlled to operate. The moving plate 14 is driven to move, which in turn drives the workpiece toward the lifting support assembly 4. After the workpiece is placed on the support table 42, the lifting support assembly 4 is controlled to move vertically a certain distance, so that the workpiece corresponds to the clamping plates of the inner positioning assembly 5 and the outer positioning assembly 15. After the workpiece position is determined, the forward and reverse movement assembly 16 is controlled to move, so that the pushing mechanism 6 moves backward and resets, waiting for the next pushing action. At the same time, the inner positioning assembly 5 moves forward and approaches the workpiece, and the outer positioning assembly 15 also moves and interacts with the inner positioning assembly 5. The workpiece is positioned and clamped in coordination to ensure its stability. Then, the lifting and grinding assembly 3 is lowered, allowing the grinding head 36 to grind the workpiece. After grinding, the forward and reverse movement assembly 16 is controlled to move, specifically causing the pushing mechanism 6 to push the material conveyed from the front forward again. Simultaneously, the inner positioning assembly moves backward and, together with the outer positioning assembly 15, disengages from the workpiece. The lifting and bearing assembly 4 moves downward, aligning the workpiece with the transfer plate 14. Then, the transverse drive cylinder 9 is controlled to move, pushing the processed workpiece towards... One side pushes out, while the other side conveys the material from the pusher mechanism 6 to the processing position, waiting for the next work to proceed. After the workpiece is conveyed out, the longitudinal drive cylinder 12 is controlled to run, so that the transfer plate 14 moves away from the workpiece. When it moves to the right side, the longitudinal drive cylinder 12 is controlled to run in the opposite direction, especially driving the transfer plate 14 to be adjusted back to the original position. This process is repeated, which not only realizes the convenient loading of workpieces and ensures the smooth progress of grinding work, but also improves the functionality of the device and meets different usage needs. In the above process: the lifting and grinding component 3 and the lifting and bearing component 4 work together to lift the workpiece away from the transfer plate 14, preventing equipment damage. Simultaneously, the lifting and grinding component 3 completes the grinding process, improving the functionality of the equipment. The pushing mechanism 6 replaces manual workpiece loading, reducing labor intensity and ensuring smooth production. The internal positioning component 5 and the external positioning component 15 work together to position the workpiece correctly. Convenient positioning reduces the possibility of displacement, ensuring grinding effect and meeting usage requirements. This device is reasonably designed, simple in structure, easy to process, and can replace manual labor to automatically feed workpieces, reducing labor intensity and ensuring work progress. At the same time, the feeding process and material positioning function work together. Even after the external material is successfully transported to the feeding position, the workpiece is transported to the processing position, and the material positioning function at the aforementioned position resets to wait for the next material to be pushed. Meanwhile, the material positioning function plays a role in positioning the workpiece to ensure the smooth progress of processing and meet usage requirements.
[0018] To facilitate convenient grinding of workpieces and ensure precise forming, the lifting grinding assembly 3 includes a frame 31. A vertical slide bar 32 is provided on one side of the frame 31, and a vertical moving plate 33 is provided on one side of the vertical slide bar 32. A vertical drive cylinder 34 is provided on one side of the vertical moving plate 33, with its output end connected to the top of the frame 31. A drive motor 35 is located on the upper outer side of the vertical moving plate 33, and a grinding head 36 is located at the output end of the drive motor 35. Specifically, the extension of the vertical drive cylinder 34 drives the vertical moving plate 33 to move vertically up and down, thereby causing the drive motor 35 and the grinding head 36 to move downwards, specifically bringing the grinding head 36 closer to the workpiece. To further explain how the workpiece is polished, the grinding head 36 has a grinding component, such as a grinding wheel (not shown in the figure), located in the middle. A brush assembly 43 is also positioned on the outer side of the grinding component. The arrangement of the grinding head 36 and brush assembly 43 is similar to that of the support platform 42. Once the grinding head 36 is adjusted to the appropriate position, the drive motor 35 is controlled to rotate and act on the grinding head 36, causing the middle part to grind the workpiece. The brush assembly 43 on the outer side serves to block the grinding debris, preventing it from splashing and affecting the cleanliness of the work area, thus improving the work process.
[0019] To ensure the smooth execution of the grinding work, the lifting support assembly 4 includes a vertical lifting cylinder 41 connected to the lower part of the high platform 1. The output end of the vertical lifting cylinder 41 is provided with a support platform 42, and a brush 43 is provided on the outer side of the support platform 42. Specifically, the vertical lifting cylinder 41 is fixedly connected to the lower part of the high platform 1, and a circular hole is opened at the high platform 1 corresponding to its output end, which corresponds to the support platform 42. When the workpiece is transported to the support platform 42 by the transfer plate 14, the vertical lifting cylinder 41 is controlled to rise a certain distance, so that the workpiece is higher than the transfer plate 14, preventing the subsequent grinding process from damaging the transfer plate 14. Of course, the brush 43 is made of soft material such as silicone or plastic. When it rises, it will not be damaged by the transfer plate 14. After it falls, the brush 43 will return to its original position. The brush 43 is used to a certain extent to block the waste generated after grinding, preventing it from flying out and affecting the cleanliness of the processing area. At the same time, the brush 43 is used to block the waste generated after grinding to a certain extent, preventing it from flying out and affecting the cleanliness of the processing area.
[0020] To limit the position of the workpiece and ensure its accuracy, the inner positioning component 5 includes a concave frame 51 that can slide longitudinally relative to the lower outer side of the upright 31. A suction head 52 is installed inside the concave frame 51 and is connected to the concave frame 51. The suction hose connecting to the suction head 52 extends through the bottom of the upright 31, allowing the suction head 52 to move easily during operation. The other end of the suction hose of the suction head 52 is connected to an external dust collection device. When the workpiece is being polished, the external dust collection device operates, and the suction head 52 cleans the polished area, ensuring cleanliness during processing and improving the efficiency of the equipment. For functionality, the concave frame 51 has an inner clamping plate 53 on its outer side. Specifically, the inner side of the concave frame 51 has a slot, and a rod is provided below the upright frame 31 corresponding to the slot. This rod limits the movement of the concave frame 51 and ensures the stability of its position. In other words, the operation of the forward and reverse movement component 16, especially the movement of the first rack 164, acts on the concave frame 51, allowing it to move longitudinally relative to the upright frame 31. This causes the inner clamping plate 53 to move and act on the workpiece on the grinding table, completing the positioning and clamping of the workpiece on its outer side. This works in conjunction with the outer positioning component 15 to ensure the stability of the workpiece's position, providing convenient conditions for subsequent grinding work.
[0021] To facilitate the convenient pushing of workpieces, it needs further explanation: the high platform 1 on the front side of the pushing mechanism 6 is used to receive materials conveyed by the external conveyor belt. That is, the end of the external conveyor belt can use an inclined plate or equivalent component to slide the workpiece to the front of the pushing mechanism 6, ensuring smooth subsequent material loading. Specifically, the pushing mechanism 6 includes a mounting frame 61 connected to the high platform 1. A slide rail 62 is provided on the mounting frame 61, and a slide block 63 is provided on the slide rail 62. A sliding plate 64 with a mountain-shaped design is provided above the slide block 63. A top plate 65 is provided on one side of the sliding plate 64. A keyway 621 is opened in the slide rail 62, and a limit rod 66 is provided in the sliding plate 64, which is adapted to the keyway 621. Specifically, the middle position of the sliding plate 64 is connected to one side of the slide block 63. The sliding plate 63 and sliding plate 64 can move relative to the slide rail 62. In use, the forward and reverse movement component 16 provides driving power and acts on the sliding plate 64, causing it and the sliding block 63 to move relative to the slide rail 62. The limit rod 66 can limit its movement direction. The movement of the sliding plate 64 drives the top plate 65 to move, so that the workpiece located in front of it is pushed to the middle position of the adjacent transfer plate 14, ensuring the smooth progress of the workpiece loading operation and meeting the usage requirements. It should be further explained that after the pushing mechanism 6 pushes the workpiece to the transfer plate 14, it can first control the pushing mechanism 6 to move backward a certain distance, and make the top plate 65 disengage from the workpiece. During this process, the inner clamping plate 53 moves slightly away from the transfer plate 14, and does not affect the movement process of the transfer plate 14, which greatly improves the rationality of the device and meets the usage requirements.
[0022] To ensure the alternating operation of the workpiece loading and positioning functions and effectively improve the functionality of the equipment, a forward and reverse movement component 16 is provided between the internal positioning component 5 and the pushing mechanism 6. The forward and reverse movement component 16 includes a mounting base 161, with a drive gear 162 on one side of the mounting base 161. A drive shaft 163 is housed within the drive gear 162. It should be further noted that the mounting base 161 limits the position of the drive gear 162, allowing the drive gear 162 to rotate. The drive shaft 163 is stably connected to the drive gear 162, and a motor is installed below the high platform 1 to provide driving power. The upper end of the drive shaft 163 rotates relative to the mounting base 161. Thus, the motor provides driving power to the drive shaft 163, causing the drive gear 162 to rotate and mesh with the first rack 164 and the second rack 165. This facilitates the transmission of driving power and allows for the staggered movement of the inner positioning assembly 5 and the pushing mechanism 6. The first rack 164 is located on the outer side of the concave frame 51 near the drive gear 162, and the second rack 165 is located on the outer side of the sliding plate 64 near the drive gear 162. The first rack 164 and the second rack 165 are arranged symmetrically about the drive gear 162. Specifically, when the externally conveyed workpiece is transported to the position in front of the pusher mechanism 6, the inner positioning component 5 is in a state of cooperation with the outer positioning component 15. After the workpiece is processed, the drive gear 162 is controlled to rotate. Its meshing with the first rack 164 and the second rack 165 drives the inner clamping plate 53 backward by driving the first rack 164. On the other hand, the drive gear 162 drives the second rack 165 to drive the sliding plate 64 to move, and causes the top plate 65 to push the workpiece toward a position close to the transfer plate 14. Afterwards, the horizontal drive cylinder 9 is moved and acts on the horizontal plate, causing the transfer plate 14 to move longitudinally. On the one hand, it can move the finished workpiece out from the grinding position, and on the other hand, it can transport the material pushed by the pushing mechanism 6 towards the grinding position. Of course, during the above-mentioned conveying process, the lifting and bearing component 4 has been reset, and the workpiece and the transfer plate 14 are on the same plane, ensuring the smoothness of the output process. The above process can not only replace manual labor to complete the convenient loading of workpieces, but also output the finished workpieces, greatly improving the functionality of the device, reducing labor intensity, and meeting the usage requirements.
[0023] To further improve the rationality of the device setup, the outer positioning component 15 includes a connecting frame 151 connected to the carrier frame 13. A positioning drive cylinder 152 is provided above the connecting frame 151, and an outer clamping plate 153 is provided at the output end of the positioning drive cylinder 152. Specifically, when a workpiece to be processed is placed on the lifting and bearing component 4 and the workpiece is lifted to a certain height, the inner positioning component 5 is controlled to operate synchronously to clamp the inner side of the workpiece. Then, the positioning drive cylinder 152 of the outer positioning component 15 is controlled to operate, causing it to drive the outer clamping plate 153 to move and approach the workpiece, so that it cooperates with the inner clamping plate 53 to complete the clamping of the workpiece's position, ensuring the stability of its position and ensuring the smooth progress of subsequent grinding work. Of course, after the workpiece is lifted to a certain height, the cooperation between the inner positioning component 5 and the outer positioning component 15 needs to be adapted to its height. That is to say, the positions of the inner clamping plate 53 and the outer clamping plate 153 are both higher than the transfer plate 14, which improves the rationality of the device setup.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
