Description

Technical Field

[0001] This utility model relates to the field of bolt processing technology, specifically to a blade bolt processing device. Background Technology

[0002] Blade bolts are critical fasteners connecting the blades to the hub in wind turbines. A blade bolt consists of the optical shaft section and threaded sections at both ends of the shaft section. Currently, the processing of blade bolts typically involves workers first placing one end of the workpiece into a thread rolling machine to create threads, then removing the workpiece and repeating the process to machine the threads at the other end. This continuous manual operation for machining the threads at both ends of the blade bolts is not only labor-intensive and inefficient but also costly, hindering the company's market competitiveness. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a blade bolt processing device, which solves the problems of low efficiency and high cost in manually processing the threaded section of blade bolts.

[0004] The technical solution adopted in this utility model is as follows: A blade bolt processing device includes a first thread rolling machine and a second thread rolling machine. The first thread rolling machine has a feeding device on one side. The device also includes: The gripper mechanism is respectively installed above the No. 1 thread rolling machine and the No. 2 thread rolling machine. The gripper mechanism is equipped with a lateral displacement mechanism, a longitudinal displacement mechanism and a lifting mechanism. The No. 1 feeding plate is set between the feeding device and the No. 1 thread rolling machine and is arranged at a downward inclination toward the No. 1 thread rolling machine. Support seats are respectively installed at the front end of thread rolling machine No. 1 and thread rolling machine No. 2; The No. 1 conveyor is located between the No. 1 thread rolling machine and the No. 2 thread rolling machine; The material pushing mechanism is located at the end of the No. 1 conveying device; The No. 2 feeding plate is located between the pushing mechanism and the No. 2 thread rolling machine and is arranged at a downward inclination towards the No. 2 thread rolling machine. The material blocking mechanism is respectively installed at the discharge end of the No. 1 feeding plate and the No. 2 feeding plate; The second conveyor is located on the other side of the second thread rolling machine.

[0005] The two sets of lateral displacement mechanisms are mounted on the longitudinal displacement mechanism, the lifting mechanisms are respectively mounted on the outer side wall of the lateral displacement mechanism, and the gripper mechanism is mounted on the lifting mechanism.

[0006] The gripper mechanism includes a bidirectional cylinder, and the piston rods on both sides of the bidirectional cylinder are respectively connected to clamping plates.

[0007] The clamping surface of the clamping plate is provided with an elastic anti-slip pad.

[0008] The support base is equipped with a pair of support rollers.

[0009] The feeding mechanism includes a pusher plate and a No. 1 cylinder. A baffle is provided on the side of the pusher plate near the No. 1 thread rolling machine. The baffle is arranged perpendicular to the pusher plate.

[0010] The material blocking mechanism includes a first block and a second block arranged in pairs. The first block is located in front of the second block, and the top surface of the first block gradually slopes downward toward the second block. A third block is provided between the first blocks. Part of the third block is located in front of the first block and its length is less than or equal to the diameter of a blade bolt. The third block is equipped with a second cylinder, and the top surface of the third block gradually slopes downward toward the second block.

[0011] The beneficial effects of this utility model are: The blade bolts to be processed enter the first feeding plate through the feeding device. After moving a certain distance within the first feeding plate, the blade bolts are stopped by the blocking mechanism and then fed into the first thread rolling machine by the gripper mechanism to roll one end of the bolt. The other end of the blade bolt is supported by the support seat. After the thread rolling is completed, it is fed into the first conveying device by the gripper mechanism. The end of the first conveying device is equipped with a contact sensor. When the blade bolt contacts the contact sensor, the pushing mechanism pushes it into the second feeding plate. The other end of the blade bolt is fed into the second thread rolling machine by the gripper mechanism again for thread rolling. After processing, it is fed into the second conveying device by the gripper mechanism to be conveyed to the next station. This realizes fully automatic processing of the threads at both ends of the blade bolts, which not only has high work efficiency but also reduces labor costs. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments: In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a blade bolt processing device includes a first thread rolling machine 1 and a second thread rolling machine 2. The first thread rolling machine 1 has a feeding device 3 on one side. The device also includes: The gripper mechanism 4 is respectively set above the No. 1 thread rolling machine 1 and the No. 2 thread rolling machine 2. The gripper mechanism 4 is equipped with a transverse displacement mechanism 5, a longitudinal displacement mechanism 6 and a lifting mechanism 7. The No. 1 feeding plate 8 is set between the feeding device 3 and the No. 1 thread rolling machine 1 and is arranged to be inclined downward towards the No. 1 thread rolling machine 1. Support bases 9 are respectively installed at the front end of thread rolling machine 1 and thread rolling machine 2; Conveying device 10 is located between thread rolling machine 1 and thread rolling machine 2; The material pushing mechanism 11 is located at the end of the first conveying device 10; The second feeding plate 12 is set between the pushing mechanism 11 and the second thread rolling machine 2 and is arranged to be inclined downward towards the second thread rolling machine 2. The material blocking mechanism 13 is respectively installed at the discharge end of the first feeding plate 8 and the second feeding plate 12; The second conveyor device 14 is located on the other side of the second thread rolling machine 2.

[0019] Conveying device 10 and conveying device 14 are belt conveyors. The gripper mechanism can move laterally, longitudinally, and vertically via lateral displacement mechanism 5, longitudinal displacement mechanism 6, and lifting mechanism 7. All three mechanisms are either screw mechanisms or sliding tables. The feeding device 3 is a chain conveyor mechanism, which is inclined upwards and equipped with baffles. The spacing between the baffles allows only one blade bolt to enter. The blade bolt moves upwards between the baffles and, upon reaching the top, moves downwards, falling from between the baffles onto feeding plate 8. After moving a certain distance within feeding plate 8, it is stopped by blocking mechanism 13. The blade bolt is fed into the No. 1 thread rolling machine 1 by the gripper mechanism 4 to roll one end of the bolt. The other end of the bolt is supported by the support seat 9. After the bolt is rolled, it is fed into the No. 1 conveying device 10 by the gripper mechanism 4. The end of the No. 1 conveying device 10 is equipped with a contact sensor. When the bolt contacts the sensor, the pusher mechanism 11 pushes it into the No. 2 feeding plate 12. The other end of the bolt is fed into the No. 2 thread rolling machine 2 by the gripper mechanism 4 again for rolling. After the bolt is processed, it is fed into the No. 2 conveying device 14 by the gripper mechanism 4 to the next station. This achieves fully automatic processing of the threads at both ends of the bolt, which not only has high work efficiency but also reduces labor costs.

[0020] In the embodiments, such as Figure 1 As shown, the two sets of lateral displacement mechanisms 5 are mounted on the longitudinal displacement mechanism 6, the lifting mechanisms 7 are respectively mounted on the outer walls of the lateral displacement mechanisms 5, and the gripper mechanisms 4 are mounted on the lifting mechanisms 7. One of the two gripper mechanisms 4 can feed materials, and the other can pick up materials, which can effectively improve work efficiency.

[0021] In the embodiments, such as Figure 5 As shown, the gripper mechanism 4 includes a bidirectional cylinder 41, with piston rods on both sides of the bidirectional cylinder 41 respectively connected to clamping plates 42. The bidirectional cylinder 41 provides stable output, and the clamping plates 42 can stably clamp the blade bolts. It is also easy to install and has low maintenance costs.

[0022] In the embodiments, such as Figure 5 As shown, the clamping surface of the clamping plate 42 is provided with an elastic anti-slip pad 43. The elastic anti-slip pad 43 is a rubber anti-slip pad, and after the clamping plate 42 clamps the blade bolt, it will not damage its surface or cause displacement.

[0023] In the embodiments, such as Figure 1 , Figure 4 As shown, the support base 9 is provided with a pair of support rollers 15. When the blade bolt is being threaded, it rotates, and the other end makes rolling contact with the support rollers 15, reducing friction with the support base 9.

[0024] In the embodiments, such as Figure 1 , Figure 3 As shown, the feeding mechanism 11 includes a pusher plate 16 and a first cylinder 17. A baffle 18 is provided on the side of the pusher plate 16 near the first thread rolling machine 1, and the baffle 18 is arranged perpendicular to the pusher plate 16. When the first cylinder 17 drives the baffle 18 to push a blade bolt to the second feeding plate 12, the baffle 18 can block the next blade bolt being conveyed, preventing the next blade bolt from being pushed out of the first conveying device 10.

[0025] In the embodiments, such as Figure 1 , Figure 2 As shown, the material blocking mechanism 13 includes a first blocking block 19 and a second blocking block 20 arranged in pairs. The first blocking block 19 is located in front of the second blocking block 20. The top surface of the first blocking block 19 gradually slopes downward toward the second blocking block 20. A third blocking block 21 is provided between the first blocking blocks 19. Part of the third blocking block 21 is located in front of the first blocking block 19 and its length is less than or equal to the diameter of a blade bolt. The third blocking block 21 is equipped with a second cylinder 22. The top surface of the third blocking block 22 gradually slopes downward toward the second blocking block 20. When multiple blade bolts to be processed enter the first feeding plate 8 or the second feeding plate 12, the foremost blade bolt is first blocked by the first stop block 19. Then, the second cylinder 22 drives the third stop block 21 to rise. Since the length of the part of the third stop block 21 located in front of the first stop block 19 is less than or equal to the diameter of a blade bolt, only one blade bolt can be lifted. The blade bolt moves along the top surface of the first stop block 19 and the third stop block 21 towards the second stop block 20. The third stop block 21 is reset, and the other blade bolts are blocked by the second stop block 20.

[0026] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
