[0002] The gearbox is a crucial mechanical component widely used in wind turbine generators. Its main function is to transmit the power generated by the wind turbine under wind force to the generator and enable it to achieve the corresponding rotational speed.

[0003] Gearboxes typically consist of an upper cover, a gear set, and a lower cover. When assembling a gearbox, the upper cover and other gearbox components are usually connected by press fitting. However, existing gearbox assembly devices directly use a robotic arm to grab the upper cover and press it onto the other parts of the gearbox by lowering the robotic arm. This results in insufficient pressing force and low assembly efficiency. Utility Model Content

[0008] A clamping assembly includes a moving component and a jaw disposed at the output end of the moving component. The jaw is used to clamp a top cover. A striking element is disposed on the jaw. The output end of the striking element faces the top cover. The moving component is used to control the jaw to transfer the top cover into the cavity. The striking element is used to strike the top cover.

[0009] Furthermore, the striking element is a cylinder or a gear and rack mechanism.

[0010] Furthermore, the gearbox cover assembly device also includes a positioning lifting component disposed on the conveying module. The positioning lifting component includes a carrier plate disposed on the conveying module, a support member disposed on the carrier plate, and a lifting cylinder for controlling the lifting of the support member. The output end of the lifting cylinder is connected to the support member, and the lifting cylinder controls the support member to lift up and down to abut against the carrier.

[0011] Furthermore, the abutment includes a support plate disposed at the output end of the lifting cylinder and a rolling element disposed on the support plate. The platform is provided with a sliding frame connected to the conveying module. The sliding frame is provided with an abutment groove, and the rolling element and the abutment groove roll against each other.

[0012] Furthermore, the carrier plate is provided with guide posts, and the supporting member is provided with mounting slots that are adapted to the guide posts. When the supporting member is raised or lowered, the guide posts pass through the mounting slots.

[0013] Furthermore, the moving component includes a first moving module, a second moving module, and a third moving module disposed at the output end of the second moving module. The output end of the first moving module is connected to the second moving module, and the output end of the third moving module is provided with a gripper cylinder, the output end of which is connected to the gripper.

[0014] Furthermore, the output end of the third moving module is provided with a first abutment plate and a second abutment plate arranged opposite to each other, a mounting shaft disposed between the first abutment plate and the second abutment plate, and a telescopic spring sleeved on the mounting shaft.

Detailed Implementation

[0026] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figure 1-7 This utility model embodiment provides a gearbox cover assembly device 100, including a platform 10, a conveying module 20, a vibrator 30, and a clamping assembly 40. The conveying module 20 is used to drive the platform 10 to move. Specifically, the conveying module 20 is a chain conveying mechanism in the prior art, and only part of the track in the conveying module 20 is shown in the figure.

[0028] A platform 10 is used to place the gearbox 200. The platform 10 has cavities 11 for placing various parts of the gearbox 200. The platform 10 is mounted on the conveyor module 20. Specifically, the bottom end of the platform 10 has a sliding frame 13 that is slidably connected to the track of the conveyor module 20. In this embodiment, the gearbox 200 includes an upper cover 201, a gear set 202, and a lower cover 203. For ease of explanation in the accompanying drawings, the upper cover 201, the assembled gearbox 200, and the gear set 202 are sequentially placed on the platform 10. This embodiment shows three cavities 11: one for placing the upper cover 201, one for placing the gear set 202, and one for placing the lower cover 203. During assembly, as shown in the figure, the gear set 202 and the upper cover 201 are sequentially placed on the lower cover 203 located in the middle cavity 11 to form the gearbox 200.

[0029] The vibrator 30 is mounted on the platform 10, and the output end of the vibrator 30 is in contact with the platform 10. Furthermore, in this embodiment, the vibrator 30 is fixedly connected to the bottom end of the sliding frame 13, and the output end of the vibrator 30 is in contact with the sliding frame 13. The vibrator 30 transmits the vibration to the cavity 11 on the platform 10 through the sliding frame 13, thereby transmitting the vibration to various parts of the gearbox 200.

[0030] The clamping assembly 40 includes a moving assembly and a jaw 41 disposed at the output end of the moving assembly. The jaw 41 is used to clamp the upper cover 201. A striking element 42 is disposed on the jaw 41. The output end of the striking element 42 faces the upper cover 201. The moving assembly controls the jaw 41 to transfer the upper cover 201 into the cavity 11. The striking element 42 is used to strike the upper cover 201.

[0031] The output end of the striking element 42 is provided with a striking plate 421. Optionally, the striking element 42 can be a cylinder or a gear and rack mechanism. In this embodiment, the striking element 42 is a rodless cylinder.

[0032] The moving assembly includes a first moving module 43, a second moving module 44, and a third moving module 45 disposed at the output end of the second moving module 44. The output end of the first moving module 43 is fixedly connected to the second moving module 44. The output end of the third moving module 45 is provided with a gripper cylinder 46, and the output end of the gripper cylinder 46 is fixedly connected to a gripper 41. Specifically, the first moving module 43, the second moving module 44, and the third moving module 45 are all existing lead screw conveying mechanisms. The first moving module 43 is arranged along the length direction of the conveying module 20, the second moving module 44 is arranged along the width direction of the conveying module 20, and the third moving module 45 is arranged along the height direction of the conveying module 20. The output end of the third moving module 45 is provided with a sliding plate 456, which slides along the height direction of the conveying module 20.

[0033] The output end of the third moving module 45 is provided with a first abutment plate 451 and a second abutment plate 452 arranged opposite to each other, a mounting shaft 453 and a slide rail 455 disposed between the first abutment plate 451 and the second abutment plate 452, and a telescopic spring 454 sleeved on the mounting shaft 453. Specifically, the first abutment plate 451 and the second abutment plate 452 are sequentially connected to the two ends of the sliding plate 456 in the length direction. There are two mounting shafts 453, two telescopic springs 454 corresponding to the mounting shafts 453, and one slide rail 455, which is located between the two mounting shafts 453. A mounting bracket 4531 for supporting the gripper cylinder 46 is slidably disposed on the mounting shaft 453. One end of the telescopic spring 454 abuts against the first abutment plate 451, and the other end of the telescopic spring 454 abuts against the mounting bracket 4531. Specifically, the mounting bracket 4531 is provided with a protrusion (not labeled in the figure) that abuts against the telescopic spring 454. The mounting bracket 4531 is provided with a sliding block 4532 that is adapted to the slide rail 455. The end of the sliding block 4532 away from the telescopic spring 454 abuts against the second abutment plate 452. Specifically, the bottom end of the sliding block 4532 abuts against the second abutment plate 452. When the third moving module 45 controls the gripper 41 and the striking member 42 to press down, the first abutment plate 451 applies downward force to the telescopic spring 454, and the telescopic spring 454 applies force to the mounting bracket 4531. The sliding block 4532 on the mounting bracket 4531 is subjected to force and abuts against the second abutment plate 452, thereby causing the mounting bracket 4531 to drive the gripper 41 and the striking member 42 to form an elastic connection with the third moving module 45. The telescopic spring 454 cooperates with the first abutment plate 451, the second abutment plate 452, the slide rail 455, and the sliding block 4532 so that when the striking part 42 and the gripper 41 contact the upper cover 201, the pressing force on the upper cover 201 is partially offset by the elastic force of the telescopic spring 454, which reduces the damage to the upper cover 201 caused by excessive pressing force and improves the assembly quality.

[0034] During the press-fitting of the upper cover 201, the gripper 41 transfers the upper cover 201 into the cavity 11 and aligns it with other components of the gearbox 200. Then, the striking element 42 strikes the upper cover 201. Simultaneously, the vibrator 30 mounted on the platform 10 and the striking element 42 work together to generate resonance, causing the upper cover 201 and other parts of the gearbox 200 to vibrate under force and gradually achieve an interference fit. Compared to the prior art where a robotic arm directly grips the upper cover 201 and presses it into the gearbox 200 by lowering the robotic arm, the pressing force is increased, thereby improving assembly efficiency.

[0035] The gearbox cover assembly 100 also includes a positioning and lifting assembly 50 disposed on the conveying module 20. The positioning and lifting assembly 50 includes a carrier plate 51 disposed on the conveying module 20, a support member 52 vertically mounted on the carrier plate 51, and a lifting cylinder 53 for controlling the lifting of the support member 52. The output end of the lifting cylinder 53 is connected to the support member 52, and the lifting cylinder 53 controls the support member 52 to lift and lower until it abuts against the platform 10. Specifically, the carrier plate 51 and the frame portion of the conveying module 20 (not shown in the figure) are fixedly connected.

[0036] The supporting member 52 includes a support plate 521 disposed at the output end of the lifting cylinder 53, a rolling member 522 disposed on the support plate 521, and a connecting plate 523 disposed on the support plate 521. The connecting plate 523 and the support plate 521 are fixed to each other by bolts, and the rolling member 522 is disposed at the top of the connecting plate 523.

[0037] The bottom end of the sliding frame 13 is provided with a support groove 12, and the rolling element 522 rolls against the support groove 12. Specifically, the rolling element 522 can be a roller or a ball bearing; in this embodiment, it is a roller. The carrier plate 51 is provided with a guide post 512, and the support plate 521 is provided with a mounting slot 5211 that matches the guide post 512. When the support element 52 rises and falls, the guide post 512 passes through the mounting slot 5211.

[0038] When the platform 10 moves to a position below the clamping assembly 40 via the conveying module 20, the lifting cylinder 53 controls the support plate 521 to rise. The support plate 521 drives the rolling element 522 to rise and roll against the abutment groove 12 on the sliding frame 13, making the platform 10 less likely to move when assembling the upper cover 201.

[0039] The working process of the gearbox cover assembly device 100 provided by this utility model is as follows: The platform 10 is moved to a position below the gripper 41 by the conveying module 20. The lifting cylinder 53 controls the support plate 521 to rise. The support plate 521 drives the rolling element 522 to rise and roll against the abutment groove 12 on the sliding frame 13, making it difficult for the platform 10 to move during the assembly of the cover 201. The gripper 41 is moved to a position above the cover 201 by the cooperation of the first moving module 43, the second moving module 44 and the third moving module 45, and the cover 201 is transferred to be aligned with the lower cover 203. Then the striking element 42 is activated, and the upper cover 201 is gradually pressed onto the lower cover 203 and the gear set 202 by the up and down movement of the striking element 42.
