Conventional remote tightening devices for expansion bolts only utilize their own length for remote tightening, which increases the difficulty of aligning the expansion bolts and affects the practicality of the remote tightening device. The "Remote Tightening Device for Expansion Bolts" disclosed on the China Patent Network uses a magnet at the tail of the expansion bolt to expand the tail of the bolt using external magnetic attraction. However, the magnetic force cannot ensure that the expanded part of the expansion bolt fully expands and contacts the inner wall of the bolt hole. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model discloses a remote fastening device for expansion bolts, comprising: a base block 1, side plates 2 at both ends of the base block 1, the base block 1 and the side plates 2 being slidably connected, the side plates 2 providing conditions for the lateral sliding adjustment of the base block 1, wherein the side plates 2 are made of iron, a round-bottomed mounting block 3 being rotatably connected to the upper surface of the base block 1, the round-bottomed mounting block 3 being rotatably connected to the base block 1 via a damping shaft, a servo motor 4 being fixedly connected inside the round-bottomed mounting block 3, the round-bottomed mounting block 3 being used to provide conditions for the servo motor 4 to change the angle of action, a long tube 5 being fixedly connected to the upper surface of the round-bottomed mounting block 3, the output end of the servo motor 4 penetrating into the interior of the long tube 5, a hexagonal clamp 7 being provided inside the long tube 5, the servo motor 4 being used to provide rotational power for the hexagonal clamp 7.

[0024] Specifically, when using the device, the surface of the expansion bolt is directly pressed into the interior of the long tube 5 and contacts the hexagonal clamp 7. As the device approaches the screw hole, the side plate 2 first contacts the part where the screw hole is located. At this time, the hexagonal clamp 7 can be pushed to slide left and right relative to the side plate 2, thereby changing the alignment position of the long tube 5.

[0025] A spring rod 6 is fixedly connected between the hexagonal collet 7 and the output end of the servo motor 4. The spring rod 6 consists of an upper protrusion 16, a compression spring 17, a lower protrusion 18, and a T-shaped long rod 19. The upper protrusion 16 is fixedly connected to the hexagonal collet 7, and the lower protrusion 18 is fixedly connected to the output of the servo motor 4. The two ends of the compression spring 17 are fixedly connected to the upper protrusion 16 and the lower protrusion 18, respectively. The lower end of the T-shaped long rod 19 is fixedly connected to the lower protrusion 18. The T-shaped end of the T-shaped long rod 19 passes through the upper protrusion 16 and engages with the hexagonal collet 7. The spring rod 6 is used to provide the thrust for the expansion bolt to enter the screw hole, ensuring that the expansion bolt is completely inserted into the screw hole.

[0026] Specifically, when the expansion bolt needs to be pressed into the screw hole, during the rotation process, the T-head rod 19 transfers the rotational stress from the lower protrusion 18 to the upper protrusion 16, thereby preventing the compression spring 17 from being subjected to torque. Therefore, the spring rod 6 is driven to rotate by the servo motor 4. During this process, the limiting mechanism 23 releases the restriction on the spring rod 6, and the compression spring 17 automatically extends to push the hexagonal chuck 7 out of the long tube 5, thereby pushing the expansion bolt into the screw hole.

[0027] A limiting mechanism 23 is provided between the hexagonal clamp 7 and the long tube 5. The limiting mechanism 23 consists of a protruding edge 21, a storage section 20, and a passage groove 22. The storage section 20 is located at the lower end of the long tube 5. When the device is not in use, the hexagonal clamp 7 is located inside the storage section 20. The passage groove 22 is located on the inner wall of the long tube 5 and communicates with the storage section 20. The protruding edge 21 is fixedly connected to the hexagonal clamp 7. When the bolt is tightened, the protruding edge 21 is located inside the passage groove 22. The limiting mechanism 23 is used to limit the compression of the spring rod 6 to prevent the spring rod 6 from extending and causing the hexagonal clamp 7 to pop out of the long tube 5 when the device is not in use.

[0028] Specifically, when adding the expansion bolt, the expansion bolt provides a thrust to the hexagonal collet 7, compressing the spring rod 6. This causes a portion of the expansion bolt to be pressed into the interior of the long tube 5. Then, the hexagonal collet 7 is rotated by rotating the expansion bolt. This manually rotates the output end of the servo motor 4 in a small range, causing the protruding edge 21 of the hexagonal collet 7 to be misaligned with the passage groove 22 after entering the storage section 20. At this time, the inner wall of the storage section 20 blocks the protruding edge 21, thus preventing the compression spring 17 from naturally extending. When it is necessary to fix the expansion bolt, the servo motor 4 is turned on to drive the spring rod 6 and the hexagonal collet 7 to rotate. During the rotation of the hexagonal collet 7 within the storage section 20, the protruding edge 21 on its surface rotates to a position symmetrical with the passage groove 22. Then, the spring rod 6 extends, pushing the expansion bolt into the interior of the screw hole.

[0029] The left and right surfaces of the side plate 2 are provided with mounting grooves 8. The upper end of the mounting groove 8 extends through the upper surface of the side plate 2. The mounting groove 8 is provided with a positioning plate 9. The positioning plate 9 is used to limit the sliding range of the base block 1. The upper and lower surfaces of the positioning plate 9 are respectively fixedly connected with rubber blocks 11 and magnet blocks 13. The front and rear surfaces of rubber blocks 11 and magnet blocks 13 are in contact with the inner wall of the slot 10. The rubber blocks 11 and magnet blocks 13 cooperate to increase the resistance of the positioning plate 9 and improve the stability of the positioning plate 9 when it is in operation. The surface of the positioning plate 9 is provided with slots 10. When the bolts are tightened, the base block 1 is located inside the slots 10. The slots 10 improve the stability of the base block 1. The lower surface of the base block 1 is provided with a socket hole 14. The socket hole 14 is provided with a connecting sleeve 12. The connecting sleeve 12 is made of plastic. The upper surface of the connecting sleeve 12 and the upper inner wall of the socket hole 14 are fixedly connected with Velcro 15. The socket hole 14 and the connecting sleeve 12 cooperate to facilitate the docking of the device with external objects such as long rods.

[0030] Specifically, when using the device, press the positioning plate 9 directly into the mounting groove 8, then insert the long rod into the docking sleeve 12 to fix the device to the upper end of the long rod. Use the long rod to push the device to a high position. During the pushing process, align the slot 10 on the surface of the positioning plate 9 with the positioning plate 9 to assist in aligning the collision bolts. After the base block 1 slides into the slot 10, the expansion bolts can be rotated and installed.

[0031] Working principle: When using the device, directly press the expansion bolt into the inside of the long tube 5, and then manually rotate the hexagonal chuck 7 to misalign the protruding edge 21 on the surface of the hexagonal chuck 7 with the passage groove 22, thereby maintaining the compressed state of the spring rod 6. While the side plate 2 is approaching the screw hole, observe the position of the positioning plate 9 by using the space between the base block 1 and the positioning plate 9 to ensure that the upper surface of the positioning plate 9 is aligned with the screw hole through the slot 10. Therefore, after the base block 1 slides into the slot 10, the long tube 5 is in a state of direct alignment with the screw hole. At this time, start the servo motor 4 at the lowest speed setting to ensure that the spring rod 6 has time to extend after the protruding edge 21 aligns with the passage groove 22. The spring rod 6 drives the hexagonal chuck 7 through the passage groove 22 to push the expansion bolt out of the long tube 5. At this time, the collision bolt collides with the screw hole. After hearing the collision sound, increase the speed of the servo motor 4 to complete the tightening of the expansion bolt.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
