Specific implementation manner

[0026] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Please refer to Figures 1 - 4 , the present utility model provides a positioning device for steel fasteners, including a fastener 4, a U-shaped force-bearing bracket 1, which facilitates the sliding connection of both sides of the force-bearing bracket 1 with the sliding groove 8. The bottom of the force-bearing bracket 1 is connected with a base 12, which makes the bottom more stable. A control panel 14 is installed on the outside of the force-bearing bracket 1, which facilitates the operation of the staff and makes the work efficiency higher. The top of the force-bearing bracket 1 is connected with a placement plate 3 through a force-bearing rod 2, and a pressure sensor 16 is installed on the upper end of the placement plate 3. And a protrusion is provided on the outer side of the top end of the placement plate 3, so that the fastener can be placed therein for convenient fixing and limiting. And under the action of the pressure sensor 16, the electric push rod 7 can be automatically pulled to achieve automation and make the work efficiency higher. And the fastener 4 is installed on the upper end of the placement plate 3.

[0028] Inside the force-bearing bracket 1, an electric push rod 7 is installed. By generating upward and downward pulling and pushing forces through the electric push rod 7, it reduces the manual force drive, making the working effect better and the efficiency higher. The output end of the electric push rod 7 is connected to a force-bearing support plate 6, and both sides of the force-bearing support plate 6 are in sliding connection with the inner wall of the force-bearing bracket 1. At both sides of the bottom end of the force-bearing support plate 6, positioning telescopic rods 13 are provided and connected to the force-bearing bracket 1, so that under the action of the positioning telescopic rods 13, the stability of the upward pulling at the upper end is enhanced, making the stability better during positioning processing. The upper end of the force-bearing support plate 6 is connected to a top cylinder 5. The inside of the top cylinder 5 is hollow. At both sides of the top cylinder 5, there are through sliding grooves 8 for sliding connection with the force-bearing bracket 1, so that when the top cylinder 5 moves up and down, it will not be blocked by the force-bearing bracket 1, facilitating the pulling of the upper side clamping plate 9. And the force rod 2 is located inside the top cylinder 5. The upper end of the top cylinder 5 is connected to a connecting top plate 15, and in the middle of the connecting top plate 15, there is a middle hole 110 for sliding connection with the force rod 2, so that the force rod 2 moves inside the top cylinder 5, making the top cylinder 5 move independently when pulled, so that the fastener 4 will not move during positioning. When the top cylinder 5 moves, it makes the fastener 4 clamped and loosened up and down. The two sides of the connecting top plate 15 are rotatably connected to L-shaped side clamping plates 9. After the side clamping plates 9 are forced to flip, the upper ends flip to the upper surface of the fastener 4, and the side clamping plates 9 apply force to the fastener 4 during the downward process, making the clamping and positioning effect of the fastener 4 better. At the bottom of the side clamping plate 9, there is a rotating groove 17, and inside the rotating groove 17, there is a connecting rotating rod 19. At both sides of the connecting top plate 15, there are rotating holes 18 for connection with the connecting rotating rod 19, so that the side clamping plates 9 can be easily flipped under the action of the rotating holes 18 and the connecting rotating rods 19, enabling the disassembly and fixing work of the fastener 4. And the inner side of the top end of the side clamping plate 9 is arc-shaped, increasing the contact surface between the side clamping plate 9 and the fastener 4, making the positioning and fixing effect better.

[0029] Preferably, at both sides of the top end of the force-bearing bracket 1, a rotating rod 11 is rotatably connected through a fixed rod 10. When the rotating rod 11 rotates, during the downward pulling and flipping process of the side clamping plate 9, the rotating rod 11 supports the side clamping plate 9, enabling the working side clamping plate 9 to automatically clamp and position the fastener 4, avoiding manual operation and making the working effect better.

[0030] Working principle: When in use, first connect the electric push rod 7, the control panel 14 and the pressure sensor 16 to an external power supply. Then place the fastener 4 on the pressure sensor 16 on the placement plate 3. When the pressure sensor 16 is stressed, start the electric push rod 7 to pull the force-bearing support plate 6 downward, so that the top cylinder 5 pulls the connecting top plate 15 downward during the downward movement, driving the side clamping plate 9 to pull and flip downward. And under the action of the rotating rod 11 at the upper end of the fixed rod 10, the side clamping plate 9 is flipped onto the fastener 4. Then, when the connecting top plate 15 is pulled downward, the side clamping plate 9 fixes and positions the fastener 4. After processing, the electric push rod 7 can be pushed upward to push the side clamping plate 9 out of the upper end of the rotating rod 11, so as to facilitate opening the side clamping plate 9 and replacing the fastener 4, thus completing the work.
