Description

Technical Field

[0001] This utility model relates to the field of gear ring processing technology, specifically a gear ring pressure forming tool. Background Technology

[0002] The gear ring is a workpiece that is heated and then inlaid on the outer edge of the flywheel. After cooling, it is fastened to the outer edge of the flywheel and used to mesh with the starter gear to drive the crankshaft to rotate. During heat treatment, in order to prevent deformation, the gear ring needs to be fixed and limited by a forming fixture.

[0003] Currently, when fixing a gear ring, the fixture places the gear ring into the fixture and then rotates multiple sets of threaded rods within the fixture. When all the threaded rods are in contact with the outer side of the gear ring, the gear ring can be fixed, thus solving the problem of elliptical deformation during heat treatment. However, the flatness of the gear ring cannot be effectively controlled, affecting subsequent assembly and ultimately impacting product performance and lifespan. Furthermore, existing shaping fixtures that limit the flatness of the gear ring use rectangular extrusion blocks at the bottom of the crossbeam to press the top two sides of the gear ring during installation, thereby clamping it. To ensure that the extrusion blocks contact the sides of the gear ring, the position of the gear ring needs to be manually adjusted to be centered, which is quite cumbersome. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-6 The illustrated gear ring pressurizing and shaping fixture includes a base plate 1 and a bidirectional threaded rod 8. A channel steel frame 2 is welded and fixedly connected to the top center of the base plate 1. Threaded rods a3 are welded and fixedly connected to both sides of the top of the channel steel frame 2. A lever beam 4 is connected through the outer side of the threaded rod a3. A nut 5 is set on the top of the lever beam 4, and the outer side of the nut 5 is threadedly connected to the threaded rod a3. The bottom of the nut 5 is attached to the lever beam 4 through a connecting plate. A pressurizing beam 6 is connected to the bottom of the lever beam 4. A square key 7 is set at the bottom of the pressurizing beam 6. An adjustment mechanism is set inside the square key 7, which includes a fixing plate 9. A positioning mechanism is set inside the channel steel frame 2. Specifically, the arrangement of multiple sets of nuts 5 can evenly transmit the pressing force to the pressurizing beam 6 and the square key 7, thereby pressing the gear ring at the bottom.

[0021] Please see Figure 1The fixing plate 9 is fixedly connected to the bottom of the pressure beam 6. The interior of the fixing plate 9 is rotatably connected to the bidirectional threaded rod 8 through the bearing. Both ends of the bidirectional threaded rod 8 are threadedly connected to the square key 7. The top of the square key 7 abuts against the pressure beam 6. The bidirectional threaded rod 8 and the square key 7 form a threaded transmission structure. Specifically, since the top of the square key 7 abuts against the bottom of the pressure beam 6, the square key 7 will not rotate when the bidirectional threaded rod 8 rotates, and the square key 7 will move in a straight line.

[0022] In this embodiment, when adjusting the flatness of the gear ring, the gear ring is placed on the channel steel frame 2, and then the square key 7 at the bottom of the pressure beam 6 is moved to contact the two sides of the top of the gear ring. Subsequently, multiple sets of nuts 5 can be rotated, and the nuts 5 will be threaded with the threaded rod a3, thereby moving down to squeeze the lever beam 4. The lever beam 4 will transmit the squeezing force through the pressure beam 6 to the square key 7, thereby pressing the bottom gear ring, maximizing the flatness adjustment of the part, so that the product reaches a certain deformation, and finally stress relief and shaping are achieved through low-temperature tempering. In order to press gear rings of different diameters, the bidirectional threaded rod 8 can be rotated to thread with the two sets of square keys 7, driving the two sets of square keys 7 to move, thereby adapting to gear rings of different diameters.

[0023] Example 2: Please refer to Figures 1-6 This embodiment further illustrates Example 1. The positioning mechanism shown in the figure includes a handle 10, which is rotatably connected to the inside of the base plate 1 via a bearing. One end of the handle 10 is fixedly connected to a bevel gear a11. A bevel gear b12 meshes with the outer side of bevel gear a11. The top of bevel gear b12 is fixedly connected to a bevel gear c13 via a connecting shaft. Multiple sets of bevel gears d14 mesh with the outer side of bevel gear c13, and a threaded sleeve 15 is welded and fixedly connected to one side of each set of bevel gears d14. The outer side of the threaded sleeve 15 is rotatably connected to the channel steel frame 2 via a bearing. The threaded sleeve 15 has a threaded rod b16 internally connected to it. One end of the threaded rod b16 is provided with a toggle block 17. The outer side of the toggle block 17 is slidably connected to the channel steel frame 2. A telescopic mechanism is provided on one side of the toggle block 17. One end of the handle 10 is provided with a limit mechanism. The threaded rod b16 and the threaded sleeve 15 form a threaded transmission structure. The top of the channel steel frame 2 is provided with a moving groove that matches the toggle block 17. The channel steel frame 2 and the toggle block 17 form a sliding structure. The arrangement of multiple sets of bevel gears d14 can make multiple sets of toggle blocks 17 move synchronously, thereby positioning the gear ring.

[0024] Please see Figure 2 , Figure 4 and Figure 5The telescopic mechanism shown in the figure includes a slider 18, which is fixedly connected to the end of the threaded rod b16. One side of the slider 18 is slidably connected to the actuating block 17. The bottom of the actuating block 17 abuts against a guide plate 19. Both the guide plate 19 and one end of the actuating block 17 are wedge-shaped. A groove matching the slider 18 is provided on one side of the actuating block 17. The slider 18 and the actuating block 17 form a sliding structure. Specifically, since the outer side of the actuating block 17 is slidably connected to the channel steel frame 2, the actuating block 17 and the threaded rod b16 will not rotate. When the threaded sleeve 15 rotates, the threaded rod b16 will move.

[0025] Please see Figure 1 , Figure 3 and Figure 6 The limiting mechanism shown in the figure includes a fixing block 20, which is welded and fixed to one side of the base plate 1. A plug rod 21 is slidably connected inside the fixing block 20. A spring 22 is sleeved on the outside of the plug rod 21. One end of the spring 22 abuts against the fixing block 20. A slot matching the plug rod 21 is opened on the outside of the handle 10, and the slot engages with the plug rod 21. The plug rod 21 and the fixing block 20 form a sliding structure.

[0026] Please see Figure 6 In the figure, the end of the insertion rod 21 away from the handle 10 is fixedly connected to the locking block 23, and the bottom plate 1 has a limiting groove 24 that matches the locking block 23 on the side near the insertion rod 21.

[0027] In this embodiment, to ensure that the square key 7 can contact both sides of the gear ring, the gear ring needs to be positioned in the center of the channel steel frame 2. By rotating the handle 10, the bevel gear a11 at the end rotates, and the bevel gear a11 meshes with the bevel gear b12, thereby causing the bevel gear b12 and its top bevel gear c13 to rotate. The bevel gear c13 meshes with multiple sets of bevel gears d14, thereby driving the threaded sleeve 15 on one side to perform threaded transmission with the threaded rod b16, thereby causing the threaded rod b16 and its end actuating block 17 to move. When the actuating block 17 moves, the wedge-shaped surface at the bottom contacts the wedge-shaped surface at one end of the guide plate 19, and then moves upward. When the actuating block 17 is at the outermost edge position, it retracts back into the channel steel frame 2. Inside, the top of the channel steel frame 2 is flat and without protrusions, making it easy to push the gear ring into the top of the channel steel frame 2. The actuating block 17 will slide on the outside of the slider 18. As the actuating block 17 moves upward, it will contact the outside of the gear ring and push the gear ring closer to the center. When multiple sets of actuating blocks 17 are in contact with the outside of the gear ring, the gear ring will be in the center position. When it is necessary to limit the handle 10 to prevent it from rotating at will, the insert rod 21 can be rotated to drive the outer locking block 23 to disengage from the locking groove 24. At this time, the spring 22 will reset and push the insert rod 21 to engage with the handle 10, thus completing the limitation of the handle 10. In this way, the gear ring can be limited through the above operation, and the flatness of the parts can be adjusted to the maximum extent.

[0028] It should be noted that when adjusting the flatness of the gear ring, the gear ring is placed on the channel steel frame 2, and then the square key 7 at the bottom of the pressure beam 6 is moved to contact the two sides of the top of the gear ring. Subsequently, multiple sets of nuts 5 and threaded rods a3 can be rotated to perform threaded transmission, thereby moving down to squeeze the lever beam 4. The lever beam 4 will transmit the squeezing force through the pressure beam 6 to the square key 7, thereby pressing the bottom gear ring, maximizing the flatness of the part, and making the product achieve a certain deformation. At the same time, the gear ring can be positioned at the center of the channel steel frame 2 through the positioning mechanism, so that the square key 7 can press the gear ring.

[0029] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
