Description

Technical Field

[0001] This utility model belongs to the field of gear ring processing technology, and in particular relates to a clamping device for gear ring production. Background Technology

[0002] Currently, the machining of gear rings often involves positioning them. However, due to the special structure of gear rings, customized tooling fixtures are required for positioning during production. During gear ring machining, the clamping position of the gear ring is typically adjusted based on its machining location. For example, a gear ring consists of an inner and outer ring, and the machining process may require separate machining of either the inner or outer ring. However, existing clamping equipment may not be able to adjust the clamping position according to the gear ring's machining location, leading to certain drawbacks and making the equipment less convenient to use. This affects the equipment's practicality and ease of use. For example, patent number CN202322797488.2 exhibits this problem, failing to adjust the clamping position based on the gear ring's machining location, thus impacting its usability. Utility Model Content

The number of slide rods is the same as the number of outer ring plates, and the outer ring plates are fixedly disposed on the slide rods. A spring for resetting is sleeved on the slide rod, and a pressing assembly for driving the slide rod is also provided on the outside of the slide rod.

[0009] As a preferred embodiment of this utility model, the extrusion assembly includes an extrusion block fixedly disposed at the end of a slide bar, a rotating disk rotatably disposed on a worktable and located outside the mounting disk, and a plurality of wedge-shaped path plates corresponding to the extrusion block are fixedly disposed on the rotating disk.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes an outer ring plate in the equipment to effectively clamp the outer edge of the gear ring. This prevents the equipment from being unable to process the inner ring of the gear ring due to clamping limitations. Similarly, the inner arc plate in the equipment can effectively clamp the inner ring of the gear ring, enabling the equipment to process the outer ring of the gear ring.

A pressing assembly for driving the slide rod 5 is also provided on the outside of the slide rod 5, which drives the plurality of outer ring plates 2 to move closer to the center of the mounting plate 4, thereby effectively clamping the gear ring and maintaining its clamping stability.

[0027] As a preferred embodiment of this utility model, the extrusion assembly includes an extrusion block 9 fixedly disposed at the end of the slide bar 5, a rotating disk 7 rotatably disposed on the worktable 1 and located outside the mounting disk 4, and a plurality of wedge-shaped path plates 8 corresponding to the extrusion block 9 fixedly disposed on the rotating disk 7, which facilitates the simultaneous driving of several outer ring plates 2 to move at the same time, thereby effectively improving the clamping efficiency of the equipment, while ensuring that the toothed ring is located at the axial position of the mounting disk 4 during clamping.

[0028] As a preferred embodiment of this utility model, the inner ring fixing assembly further includes a fixing ring 12 fixedly mounted on the worktable 1. A lead screw 10 is slidably connected inside the fixing ring 12. A rotating ring 11 is rotatably mounted at the end of the lead screw 10. Several support rods 13 are hinged to the rotating ring 11 and the fixing ring 12 respectively. Every two support rods 13 form a group, and the end of each group of support rods 13 is hinged to the inner arc plate 3. A rotating sleeve 14 is rotatably mounted at the bottom of the worktable 1, and the lead screw 10 is threadedly connected inside the rotating sleeve 14. A telescopic limiting post 15 is provided between the lead screw 10 and the worktable 1 for guiding the movement of the lead screw 10, which facilitates internal reinforcement of the gear ring and ensures its reinforcement stability. At the same time, it can be clamped and separated from the outer ring to achieve the effect of clamping the equipment as needed.

[0029] As a preferred embodiment of this utility model, the drive assembly includes a gear ring 16 mounted on the outside of the rotating disk 7; a first gear 17 fixedly mounted on the rotating sleeve 14; a gearbox 18 fixedly mounted on the workbench 1, and the gearbox 18 is connected to the gear ring 16 via a transmission component. A second gear 19 is mounted on the gearbox 18. A drive motor 20 is mounted on the lower side of the workbench 1, and the output end of the drive motor 20 is provided with two half gears 21. The two half gears 21 alternately mesh with the first gear 17 and the second gear 19, respectively, which facilitates the separation and movement of the outer ring plate 2 and the inner arc plate 3, thereby achieving stability and convenience of the equipment in clamping.

[0030] The working principle of this utility model:

[0031] refer to Figure 1 The inner arc plate 3 is located inside the outer ring plate 2. The equipment has two clamping methods, which are determined by the clamping position of the gear ring, thereby reducing the drawbacks of using the equipment and improving the ease of clamping.

[0032] For outer ring clamping method, please refer to [reference]. Figure 3 The gear ring is placed between several outer ring plates 2, and the drive motor 20 is driven to rotate in the forward direction. When the drive motor 20 rotates in the forward direction, refer to Figure 2 One of the half gears 21 on the drive motor 20 drives the second gear 19 to rotate in the forward direction. At this time, the gearbox 18 increases its output speed, so that the transmission component can quickly drive the gear ring 16 to rotate. When the gear ring 16 rotates, the gear ring 16 drives the rotating disk 7 to rotate in the forward direction. When the rotating disk 7 rotates in the forward direction, the path plate 8 on the rotating disk 7 begins to squeeze the squeezing block 9, so that the squeezing block 9 gradually pushes the slide rod 5 to move. When multiple slide rods 5 are squeezed by the path plate 8, several outer ring plates 2 gradually move towards the axis of the mounting disk 4, so as to effectively reinforce the gear ring. During the reinforcement of the gear ring, the spring 6 is gradually compressed. When the gear ring is finished, the drive motor 20 rotates in the reverse direction, so that the outer ring plates 2 gradually move away from the gear ring 16, and the spring 6 gradually returns to its original position.

[0033] Inner ring clamping method, refer to Figure 1 The gear ring is placed on the outside of several inner arc plates 3, while the drive motor 20 rotates in the opposite direction. (Refer to...) Figure 2 When the drive motor 20 rotates in the reverse direction, the other half gear 21 drives the first gear 17 to rotate in the reverse direction. When the first gear 17 rotates in the reverse direction, refer to Figure 4 The first gear 17 drives the rotating sleeve 14 to rotate in the opposite direction. When the rotating sleeve 14 rotates in the opposite direction, the lead screw 10 will gradually move downward due to the limit of the limit post 15. When the lead screw 10 moves downward, since the fixed ring 12 is in a fixed state and the lead screw 10 passes through the fixed ring 12, the lead screw 10 will pull the rotating ring 11 downward. When the rotating ring 11 moves downward, the support rod 13 between the rotating ring 11 and the fixed ring 12 will gradually expand, thereby causing the inner arc plate 3 to gradually expand. When multiple inner arc plates 3 expand in a circular shape, the inner arc plate 3 can effectively fix the inner side of the gear ring, and then effectively fix the gear ring from the inside. After the gear ring is processed, it is only necessary to drive the drive motor 20 to rotate in the forward direction.

[0034] This invention, through the outer ring plate 2 in the equipment, can effectively clamp the outside of the gear ring, thus preventing the equipment from being unable to process the inner ring of the gear ring due to clamping limitations. Similarly, the inner arc plate 3 in the equipment can effectively clamp the inner ring of the gear ring, enabling the equipment to process the outer ring of the gear ring. The cooperation between the inner arc plate 3 and the outer ring plate 2 effectively reduces the drawbacks of the equipment during use, further improving its practicality and ease of use, while also reducing the steps required to change the fixtures.
