Description

Technical Field

[0001] This utility model relates to the field of three-section expansion bolt assembly technology, specifically to a three-section expansion bolt assembly platform. Background Technology

[0002] Three-section expansion bolts are building fasteners consisting of a screw, three-section expansion tubes, and a nut. When the nut is tightened, the tapered tail of the screw squeezes the expansion tube, causing its three sections to expand evenly and fit against the inner wall of the drilled hole. They achieve a firm fixation through friction and interlocking force. They are characterized by strong fixing force, convenient installation, and compatibility with various substrates, and are suitable for heavy equipment, brackets, and other scenarios that require stable fixation.

[0003] After the three-section expansion bolt is manufactured, the operator needs to thread the three-section expansion tube and nut onto the screw to assemble the three-section expansion bolt. The existing assembly method usually involves the operator holding the screw through the three-section expansion tube and screwing it into the nut. This assembly method requires the operator to frequently pick up and remove the screw, which makes it difficult to ensure the continuity of the three-section expansion bolt assembly and reduces the efficiency of the three-section expansion bolt assembly.

[0021] 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.

[0022] Please see Figures 1 to 4 A three-section expansion bolt assembly platform includes a frame 1, and further includes a conveyor belt 2, limiting rods 3, and clamping plates 4. The conveyor belt 2 is installed inside the frame 1 through a conveying mechanism, which is used to continuously convey multiple screws. There are two limiting rods 3, which are respectively installed on both sides of the frame 1 through a moving mechanism. The moving mechanism is used to adjust the distance between the two limiting rods 3. There are two clamping plates 4, which are respectively located on the two limiting rods 3. Clamping mechanisms are provided on both sides of the frame 1, and the two clamping mechanisms are used to drive the two clamping plates 4 to clamp and fix the screws.

[0023] The conveying mechanism includes: a conveyor shaft 5, a first motor 6, and a support plate 7. There are two conveyor shafts 5, both of which are rotatably connected inside the frame 1. The conveyor belt 2 is driven between the two conveyor shafts 5. The first motor 6 is installed on one side of the frame 1. The output end of the first motor 6 passes through the frame 1 and is fixedly connected to one of the conveyor shafts 5. The support plate 7 is fixedly connected inside the frame 1. The top of the support plate 7 contacts the inner wall of the conveyor belt 2. The first motor 6 drives the conveyor shafts 5 to rotate, and the conveyor belt 2 drives the screw between the two conveyor shafts 5, thereby continuously conveying the screw.

[0024] The moving mechanism includes two slide rods 8 and two drive screws 10. Both slide rods 8 are slidably connected to the frame 1. One end of each slide rod 8 is fixedly connected to a limiting rod 3, and the other end of each slide rod 8 is fixedly connected to a drive plate 9 that supports the sliding of the two slide rods 8. One end of the drive screw 10 is rotatably connected to the frame 1. A screw hole is provided on the drive plate 9, and the drive screw 10 is threaded into the screw hole. The operator can rotate the drive screw 10 by twisting it. When the drive screw 10 rotates, it drives the drive plate 9 to move, causing the two slide rods 8 to slide on the frame 1. The sliding of the two slide rods 8 causes the limiting rods 3 to move, thereby adjusting the distance between the two limiting rods 3. This allows the two limiting rods 3 to contact the two sides of the screw during conveying, thus guiding the screw during conveying.

[0025] The clamping mechanism includes: clamping rods 11, support springs 13, a top frame 14, a transmission assembly, and a drive assembly. Two clamping rods 11 are provided, each slidably connected to a drive plate 9. One end of each clamping rod 11 is fixedly connected to the clamping plate 4, and the other end is fixedly connected to a drive frame 12 capable of driving the two clamping rods 11. The drive frame 12 has an opening, and a drive screw 10 is located within the opening. Two support springs 13 are provided, each sleeved on one of the two clamping rods 11. Both ends of each support spring 13 are fixedly connected to the drive frame 12 and the drive plate 9, respectively. The top frame 14 is fixedly connected to the top of the drive plate 9. The transmission assembly is located within the top frame 14 and is used to move the drive frame 12. The drive assembly is located on the top frame 14 and is used to drive the transmission assembly. The transmission assembly includes: a guide rod 15 and a C-ring 16. The guide rod 15 is slidably connected to the top frame 14. Inside, a C-ring 16 is fixedly connected to one end of a guide rod 15. Both ends of the C-ring 16 are fixedly connected to contact shafts 20 for moving the drive frame 12. The top of the drive frame 12 is located inside the C-ring 16. The drive assembly includes a push seat 17 and an electric cylinder 18. The push seat 17 is located inside the top frame 14. A push wheel 19 capable of moving the C-ring 16 is rotatably connected inside the push seat 17. The electric cylinder 18 is installed at the top of the top frame 14. The output end of the electric cylinder 18 passes through the top frame 14 and is fixedly connected to the push seat 17. The electric cylinder 18 drives the push seat 17 and the push wheel 19 to descend. When the push wheel 19 descends, it rolls on the C-ring 16, thereby pushing the C-ring 16 and the guide rod 15 to move. This causes the drive frame 12 to move via the contact shaft 20. When the drive frame 12 moves, it drives two clamping rods 11 to slide on the drive plate 9, thereby causing the clamping plate 4 to abut against the screw, thus fixing the screw during assembly.

[0026] Working principle: When assembling the screw, this three-section expansion bolt assembly platform needs to be connected to a centrifugal rotary feeder. The operator then rotates the drive screw 10, which in turn moves the drive plate 9. This movement causes two sliding rods 8 to slide on the frame 1. As the two sliding rods 8 slide, they move the limit rods 3, adjusting the distance between them. This ensures the limit rods 3 contact the sides of the screw during conveying, guiding the screw. The centrifugal rotary feeder then neatly places the screw onto the conveyor belt 2, which is then fed by the first motor. 6 drives the conveyor shaft 5 to rotate, and the conveyor belt 2 drives the screw between the two conveyor shafts 5 to continuously convey the screw. During assembly, the electric cylinder 18 drives the push seat 17 and the push wheel 19 to descend. When the push wheel 19 descends, it rolls on the C-ring 16, thereby pushing the C-ring 16 and the guide rod 15 to move. This, in turn, moves the drive frame 12 through the contact shaft 20. When the drive frame 12 moves, it drives the two clamping rods 11 to slide on the drive plate 9, thereby driving the clamping plate 4 to abut against the screw, thus fixing the screw during assembly. This makes it convenient for the operator to put the three-section expansion tube on the screw and tighten the nut.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
