Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker component assembly equipment, and in particular to a torsion spring shaping device for a mechanism assembly device. Background Technology

[0002] Circuit breakers are commonly used switching devices in daily life. The circuit breaker's core assembly is a crucial component, primarily responsible for normal circuit control and fault protection. The core assembly mainly includes contacts, connecting plates, and torsion springs. During assembly, it's essential to maintain a fixed angle between the torsion spring and the contacts and connecting plates to ensure proper functioning. Therefore, the torsion spring needs to be shaped during manufacturing. Current technology typically involves manually placing the torsion spring in a mold, shaping it to a standard shape, and then assembling it onto the core assembly. However, this method presents several problems: First, manual shaping can result in incomplete shaping. Second, after shaping, the torsion spring needs to be fed to the assembly station. If the interval is too long, and given the torsion spring's metal material, it may spring back to some extent, affecting the final product's yield. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a torsion spring shaping device for movement assembly that features a high degree of automation, improves product qualification rate, and ensures precise torsion spring shaping.

[0004] The technical solution of this utility model: A torsion spring shaping device for a movement assembly assembly, comprising a torsion spring feeding device, a shaping device, and a controller. The torsion spring feeding device includes a rotary vibrating feeding disc, a transmission track connected to the rotary vibrating feeding disc, and a flat vibrating motor connected to the transmission track. The shaping device includes a material distribution block, a fixed station, a fixed frame, a first sliding base slidably connected to the fixed frame, a second sliding base slidably connected to the first sliding base, a pneumatic chuck slidably connected to the second sliding base, a rotating shaft movably connected to the second sliding base, a first connecting rod fixedly connected to the rotating shaft, a second connecting rod hinged to the first connecting rod, a first hydraulic cylinder for driving the second connecting rod to move horizontally, and a controller for driving the first sliding base. The system includes a second hydraulic cylinder that slides horizontally along the base and a third hydraulic cylinder that drives the second sliding base to slide vertically. The material distribution block is provided with a first limiting groove, and the fixed station is provided with a second limiting groove. The first and second limiting grooves are respectively adapted to the shape and size of the torsion spring to be processed. The second sliding base is provided with a first shaping plate fixedly connected to the second sliding base. The bottom of the rotating shaft is provided with a second shaping plate fixedly connected to the rotating shaft. The distance between the first and second shaping plates is adapted to the diameter of the torsion spring to be processed. The controller is electrically connected to the rotating vibrating feed plate, the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the flat vibrating motor, and the pneumatic chuck.

[0005] Using the above technical solution, firstly, the torsion spring to be processed is fed into the transmission track via a rotating vibrating feed disc. Then, the controller controls the flat vibrating motor to start working, and the vibration force generated by the flat vibrating motor drives the torsion spring to be fed into the first limiting groove of the material distribution block. Then, the controller controls the second hydraulic cylinder to drive the first sliding base to slide horizontally, so that the pneumatic chuck is directly above the first limiting groove. Then, the controller controls the third hydraulic cylinder to drive the second sliding base to move vertically downward, and at the same time, the controller controls the pneumatic chuck to clamp the torsion spring. Then, the torsion spring is moved from the material distribution block to the second limiting groove on the fixed station, and then... The second hydraulic cylinder is controlled to move the first sliding base horizontally, aligning the gap between the first and second shaping plates with the second limiting groove. Then, the controller controls the first hydraulic cylinder to move the second connecting rod horizontally, which in turn moves the first connecting rod, causing the rotating shaft to rotate. This causes the second shaping plate to rotate by a certain angle until the included angle between the first and second shaping plates is the same as the included angle that needs to be formed on the two connecting ends of the torsion spring. This completes the shaping of the torsion spring. Compared with traditional shaping devices, this method greatly improves the degree of automation and ensures that the shaped torsion spring meets production requirements.

[0006] A further feature of this invention is that the second shaping plate is provided with an extension protrusion fixedly connected to the second shaping plate, and the length of the extension protrusion is less than 1 cm.

[0007] By adopting the above technical solution, since the second shaping plate is provided with an extension protrusion fixedly connected to the second shaping plate, it can prevent the torsion spring from slipping during the shaping process, causing the connecting end of the torsion spring to leave the gap range between the first shaping plate and the second shaping plate, thereby further improving the product qualification rate.

[0008] A further feature of this invention is that a positioning baffle is fixedly connected to the first sliding base, and when the second sliding base contacts the positioning baffle, the pneumatic claw is positioned directly above the first limiting groove.

[0009] By adopting the above technical solution, since the first sliding base is provided with a positioning baffle fixedly connected to the first sliding base, when the pneumatic gripper is directly above the first limiting groove, the second sliding base contacts the positioning baffle. This can ensure that the pneumatic gripper can be accurately positioned and stably clamp the torsion spring to be processed, thereby reducing the failure rate of the device.

[0010] A further feature of this invention is that the positioning baffle is provided with a sliding groove, and the sliding groove is provided with a buffer spring fixedly connected to the sliding groove and a blocking block fixedly connected to one end of the buffer spring. The blocking block is coaxially arranged with the sliding groove. When the blocking block is completely pressed into the sliding groove by the first sliding base, the pneumatic claw is located directly above the first limiting groove.

[0011] By adopting the above technical solution, since the positioning baffle is provided with a sliding groove, and the sliding groove is provided with a buffer spring fixedly connected to the sliding groove and a blocking block fixedly connected to one end of the buffer spring, when the first sliding base moves towards the direction of the first limiting groove, the first sliding base will first contact the blocking block and drive the blocking block to continue sliding along the sliding groove. During the sliding process, the compression of the buffer spring will provide a reaction force to the blocking block, thereby playing a buffering role and avoiding wear of the first sliding base after long-term use, which would cause the pneumatic clamping claw to fail to accurately enter the position, thereby further improving the processing accuracy of this device.

[0016] like Figure 1-3 As shown, a torsion spring shaping device for a movement assembly assembly includes a torsion spring feeding device 1, a shaping device 2, and a controller 3. The torsion spring feeding device 1 includes a rotary vibrating feeding disc 4, a transmission track 5 connected to the rotary vibrating feeding disc 4, and a flat vibrating motor 6 connected to the transmission track 5. The shaping device 2 includes a material distribution block 7, a fixed station 8, a fixed frame 9, a first sliding base 10 slidably connected to the fixed frame 9, a second sliding base 11 slidably connected to the first sliding base 10, a pneumatic gripper 12 slidably connected to the second sliding base 11, a rotating shaft 13 movably connected to the second sliding base 11, a first connecting rod 14 fixedly connected to the rotating shaft 13, a second connecting rod 15 hinged to the first connecting rod 14, a first hydraulic cylinder 16 for driving the second connecting rod 15 to move horizontally, and a hydraulic cylinder 16 for driving the first sliding base 10 to move horizontally. The system includes a second hydraulic cylinder 17 that slides horizontally and a third hydraulic cylinder 18 that drives the second sliding base 11 to slide vertically. The material distribution block 7 is provided with a first limiting groove 19, and the fixed station 8 is provided with a second limiting groove 20. The first limiting groove 19 and the second limiting groove 20 are respectively adapted to the shape and size of the torsion spring to be processed. The second sliding base 11 is provided with a first shaping plate 21 fixedly connected to the second sliding base 11. The bottom of the rotating shaft 13 is provided with a second shaping plate 22 fixedly connected to the rotating shaft 13. The distance between the first shaping plate 21 and the second shaping plate 22 is adapted to the diameter of the torsion spring to be processed. The controller 3 is electrically connected to the rotating vibrating feed plate 4, the first hydraulic cylinder 16, the second hydraulic cylinder 17, the third hydraulic cylinder 18, the horizontal vibration motor 6, and the pneumatic chuck 12.

[0017] First, the torsion spring to be processed is fed into the conveyor track 5 via the rotating vibrating feed disc 4. Then, the controller 3 controls the flat vibrating motor 6 to start working. The vibration force generated by the flat vibrating motor 6 drives the torsion spring to be fed into the first limiting groove 19 of the distribution block 7. Then, the controller 3 controls the second hydraulic cylinder 17 to drive the first sliding base 10 to slide horizontally, so that the pneumatic chuck 12 is directly above the first limiting groove 19. Then, the controller 3 controls the third hydraulic cylinder 18 to drive the second sliding base 11 to move vertically downward. At the same time, the controller 3 controls the pneumatic chuck 12 to clamp the torsion spring. Then, the torsion spring is moved horizontally from the distribution block 7 to the second limiting groove 20 on the fixed station 8. Then, the controller 3 controls the third hydraulic cylinder 18 to move the second sliding base 11 vertically downward. Two hydraulic cylinders 17 drive the first sliding base 10 to move horizontally, so that the gap between the first shaping plate 21 and the second shaping plate 22 is aligned with the second limiting groove 20. Then, the controller 3 controls the first hydraulic cylinder 16 to drive the second connecting rod 15 to move horizontally, thereby driving the first connecting rod 14 to move, which in turn drives the rotating shaft 13 to rotate, so that the second shaping plate 22 rotates at a certain angle until the included angle between the first shaping plate 21 and the second shaping plate 22 is the same as the included angle that the two connecting ends on the torsion spring need to be processed. This completes the shaping of the torsion spring. Compared with the traditional shaping device 2, it greatly improves the degree of automation and can improve the conformity of the shaped torsion spring to production needs.

[0018] The second shaping plate 22 is provided with an extension protrusion 23 fixedly connected to the second shaping plate 22, and the length of the extension protrusion 23 is less than 1 cm.

[0019] Since the second shaping plate 22 is provided with an extension protrusion 23 fixedly connected to the second shaping plate 22, it can prevent the torsion spring from slipping during the shaping process, causing the connecting end of the torsion spring to leave the gap range between the first shaping plate 21 and the second shaping plate 22, thereby further improving the product qualification rate.

[0020] The first sliding base 10 is provided with a positioning baffle 24 fixedly connected to the first sliding base 10. When the second sliding base 11 contacts the positioning baffle 24, the pneumatic claw 12 is located directly above the first limiting groove 19.

[0021] Since the first sliding base 10 is provided with a positioning baffle 24 fixedly connected to the first sliding base 10, when the pneumatic gripper 12 is located directly above the first limiting groove 19, the second sliding base 11 contacts the positioning baffle 24. This ensures that the pneumatic gripper can be accurately positioned and stably clamp the torsion spring to be processed, reducing the failure rate of the device.

[0022] The positioning baffle 24 is provided with a sliding groove 25. The sliding groove 25 is provided with a buffer spring 26 fixedly connected to the sliding groove 25 and a blocking block 27 fixedly connected to one end of the buffer spring 26. The blocking block 27 is coaxially arranged with the sliding groove 25. When the blocking block 27 is completely pressed into the sliding groove 25 by the first sliding base 10, the pneumatic claw 12 is located directly above the first limiting groove 19.

[0023] Since the positioning baffle 24 is provided with a sliding groove 25, and the sliding groove 25 is provided with a buffer spring 26 fixedly connected to the sliding groove 25 and a blocking block 27 fixedly connected to one end of the buffer spring 26, when the first sliding base 10 moves towards the direction of the first limiting groove 19, the first sliding base 10 will first contact the blocking block 27 and drive the blocking block 27 to continue sliding along the sliding groove 25. During the sliding process, the compression of the buffer spring 26 will provide a reaction force to the blocking block 27, thereby playing a buffering role and avoiding wear of the first sliding base 10 after long-term use, which would cause the pneumatic clamping claw to fail to accurately position itself, thereby further improving the processing accuracy of this device.
