Description

Technical Field

[0001] This utility model relates to the field of current sensor pin processing technology, and more specifically, to a current sensor pin bending device. Background Technology

[0002] A current sensor is a device that converts a current signal into a measurable electrical signal. It is used to monitor, control, and protect electrical systems. The pins of a current sensor are key interface components that connect the sensor to external circuits. Their design and quality directly affect the performance and reliability of the sensor. Some pins on current sensors need to be bent. Therefore, a current sensor pin bending device is needed to bend and crimp the pins.

[0003] Traditional current sensor pin bending devices require the current sensor to be fixed in place before use. Then, a pressure bending mechanism is used to press and bend the pin portion of the current sensor. After bending, the current sensor element is removed. However, during the bending process, the worker needs to wait for a certain period of time. When the worker fixes the current sensor, the device also needs to stop for a period of time, which reduces the efficiency of the device to some extent and makes it relatively impractical.

[0032] Working Principle: This utility model includes a worktable 2, a rotary table 4, a placement seat 6, and a fastening clamp 17. A support frame 1 is welded to the bottom surface of the worktable 2, and a connecting frame 15 is welded to the top surface of the worktable 2. A top plate 9 is welded to the top of the connecting frame 15. A stepper motor 3 is bolted to the center of the bottom surface of the worktable 2, and a stepper shaft 19 is keyed to the output end of the stepper motor 3. The rotary table 4 is bolted to the top of the stepper shaft 19. The placement seat 6 is symmetrically welded to the top surface of the rotary table 4, and several bending slots 26 are evenly distributed on the side wall of the placement seat 6. Before use, workers can evenly place several current sensors on the placement seat 6, ensuring that the current sensor pins are inserted into the bending slots 26. Both placement seats 6 have a fixed plate 16 welded to their top surfaces, and an adjusting screw sleeve 20 is welded and fixed to the fixed plate 16. A self-locking screw 21 is installed inside the adjusting screw sleeve 20. One end of the self-locking screw 21 is connected and installed on the connecting shaft seat 22, and a fastening clamp 17 is bolted to one side of the connecting shaft seat 22. A second guide slide rod 23 is symmetrically welded to the side wall of the fastening clamp 17. A second guide sleeve 24 is symmetrically welded to the fixed plate 16, and the second guide slide rod 23 is sleeved inside the second guide sleeve 24. A hand crank 18 is welded to one end of the self-locking screw 21. After the worker places the current sensor, the self-locking screw 21 can be rotated by the hand crank 18, thereby driving the fastening clamp 17 along the second guide slide rod. 23. Move until the anti-slip rubber pad 25, which is bonded and fixed to the side wall of the fastening clamp 17, comes into contact with the side wall of the current sensor, thereby clamping and fixing the current sensor to facilitate subsequent bending of the current sensor pin. This makes the bending process more stable and accurate, improving production quality and practicality. Additionally, this utility model includes a rotating table 4, a placement seat 6, a lifting plate 8, a U-shaped shaft frame 12, and a bending roller 13. An electric push rod 11 is bolted to one side of the top surface of the top plate 9, and the output end of the electric push rod 11 is bolted to the lifting plate 8. A first guide slide rod 5 is symmetrically welded to the top surface of the lifting plate 8, and a first guide sleeve 14 is symmetrically welded to the top plate 9, with the first guide sleeve 14 inner sleeve... A first guide slide rod 5 is connected to a U-shaped shaft frame 12, on which a rotating shaft 28 is mounted. A bending roller 13 is fixedly mounted on the rotating shaft 28, and several bending grooves 27 are evenly distributed on the bending roller 13. A mounting platform 10 is welded to the top of the U-shaped shaft frame 12, and the mounting platform 10 can be fixedly mounted on the lifting plate 8 by mounting bolts. As described above, after the worker fixes several current sensor elements on the placement seat 6 on one side, the stepper motor 3 can be started through the control panel 7 to drive the stepper shaft 19 and the rotating table 4 to rotate 180 degrees, thereby moving the placement seat 6 with the fixed current sensor elements to below the bending roller 13. At this time, the positioning bolts 30 on the rotating table 4 are screwed into the positioning screw holes 29 opened on the worktable 2 for positioning.To prevent the rotary table 4 from rotating during the bending process, the electric push rod 11 is activated via the control panel 7 to move the lifting plate 8 downwards along the first guide slide 5. This causes the bending roller 13 to contact the current sensor pin, which is then locked into the bending groove 27 for positioning, preventing it from shifting during bending. As the bending roller 13 continues to descend, the current sensor pin is bent along the bending groove 27, thus achieving the bending process. During the bending process, the worker can simultaneously load and fix the next batch of current sensor elements onto another placement seat 6. After the previous batch of current sensor element pins has been bent, the loaded placement seat 6 is rotated and positioned below the bending roller 13, and the above steps are repeated for bending the current sensor pins. This reduces downtime, improves efficiency, and enhances practicality.
