Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker processing equipment, and in particular to a traction rod assembly device for circuit breakers. Background Technology

[0002] A circuit breaker is a protective switch for branch circuits, housing contacts, an arc-extinguishing chamber, a trip unit, and an operating mechanism within a plastic casing. The traction rod is the core component of the operating mechanism, primarily responsible for unlocking the latch, driving the trip, and adjusting thermal protection parameters. The commonly used assembly method in existing technology involves manually placing the traction rod at the trip link of the mechanism and tightening the screws. This installation requires two steps: first, manually placing the traction rod at the trip link position of the operating mechanism, then taking the corresponding combination screws and tightening them through the traction rod to the trip link. Accurate positioning of the link is crucial during this process. This assembly method has the following drawbacks: first, low assembly efficiency and high labor costs; second, misalignment during tightening, which will affect subsequent thermal trip time tests. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a highly automated and precise assembly device for traction rods of circuit breakers.

[0004] The technical solution of this utility model: A traction rod assembly device for a circuit breaker, comprising an equipment base, a transmission device connected to the equipment base, a traction rod feeding device connected to the equipment base, a screw feeding device connected to the equipment base, and a controller. The transmission device includes a first transmission belt connected to the equipment base, a first drive motor for driving the first transmission belt, a first sliding base slidably connected to the equipment base, two first top plates fixedly connected to the first sliding base, a first hydraulic cylinder for driving a first clamping plate to move vertically upward, a second transmission belt connected to the equipment base, and a mechanism for driving the second transmission belt. The screw feeding device comprises a second drive motor, a first fixed frame fixedly connected to the equipment base, a second sliding base slidably connected to the first fixed frame, a third sliding base slidably connected to the second sliding base, a first electric clamping claw connected to the third sliding base, a first lead screw motor for driving the second sliding base to move horizontally, and a second hydraulic cylinder for driving the third sliding base to move vertically. The screw feeding device also includes a second fixed frame fixedly connected to the equipment base, a fourth sliding base slidably connected to the equipment base, a fifth sliding base slidably connected to the fourth sliding base, and a second hydraulic cylinder for driving the fourth sliding base to move horizontally. The traction rod feeding device includes a second lead screw motor, a third hydraulic cylinder for driving the fifth sliding base to move vertically, a screw-tightening element connected to the fifth sliding base, a connecting pipe connected to the screw-tightening element, a first flat vibrating track connected to the connecting pipe, a first rotary vibrating feed plate connected to the first flat vibrating track, a rotary motor for driving the screw-tightening element to rotate, and a stop assembly connected to the end of the first flat vibrating track. The traction rod feeding device also includes a second rotary vibrating feed plate, a second flat vibrating track connected to the second rotary vibrating feed plate, a sixth sliding base slidably connected to the fourth sliding base, and a second electric clamping clamp connected to the sixth sliding base. The claw and the fourth hydraulic cylinder for driving the sixth sliding base to move vertically, the distance between the two first top plates is adapted to the width of the first conveyor belt, when the fourth sliding base slides a certain distance, the screw-tightening element and the second electric clamping claw can be located directly above the first sliding base, the controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, the first electric clamping claw, the second electric clamping claw, the stop assembly, the first lead screw motor, the second lead screw motor, the first drive motor, the second drive motor, the rotary motor, the first rotary vibrating feed plate and the second rotary vibrating feed plate respectively.

[0005] Using the above technical solution, firstly, the circuit breaker to be processed is placed on the first conveyor belt. Then, the controller controls the first drive motor to move the first conveyor belt a certain distance. When the circuit breaker moves directly above the first sliding base, the controller controls the first hydraulic cylinder to move the first sliding base vertically upward. The two first push rods lift the circuit breaker vertically upward. Then, the controller controls the first rotary vibrating feed plate to move the screw to the first flat vibrating track. When the screw moves to the end of the first flat vibrating track, the controller controls the stop component to be in the open state, and the screw enters the screw-tightening element through the connecting pipe. Then, the stop component returns to the closed state, and the remaining screw cannot enter the connecting pipe. At the same time, the second rotary vibrating plate transports the connecting rod to its end through the second flat vibrating track. Then, the controller controls the second lead screw motor to move the fourth sliding base horizontally, so that the second electric clamping claw is directly above the end of the second flat vibrating track. Then, the controller controls the fourth hydraulic cylinder to move the sixth sliding base vertically downward. The second electric clamping claw then clamps the traction rod. Then, the second lead screw motor and the fourth hydraulic cylinder respectively drive the sixth sliding base vertically downward. The fourth and sixth sliding bases are moved, causing the second electric clamping jaw to move directly above the circuit breaker to be processed and place the traction rod inside the circuit breaker. Simultaneously, the controller controls the second lead screw motor to move the fourth sliding base a certain distance horizontally, positioning the screw-tightening element directly above the connection between the circuit breaker and the traction rod. Then, the controller controls the third hydraulic cylinder to move the fifth sliding base vertically downwards, and the controller controls the rotary motor to rotate the screw-tightening element, completing the traction rod assembly of the circuit breaker. The controller then controls the first drive motor to drive the first conveyor belt to continue moving, and the processed circuit breaker moves directly below the first electric clamping jaw. The first lead screw motor and the second hydraulic cylinder then drive the second and third sliding bases to move, moving the first electric clamping jaw directly above the second conveyor belt. The circuit breaker is then placed on the second conveyor belt, and the controller controls the second drive motor to drive the second conveyor belt, completing the unloading of the circuit breaker. Compared to traditional processing methods, this significantly improves automation and assembly efficiency.

[0006] Further features of this invention: The equipment base is provided with a first connecting frame, a seventh sliding base slidably connected to the first connecting frame, a first clamping plate fixedly connected to the seventh sliding base, a second clamping plate fixedly connected to the first fixed frame, and a fifth hydraulic cylinder for driving the seventh sliding base to move horizontally. The first clamping plate moves towards the second clamping plate. The first fixed frame is provided with a first fixing groove located directly above the first sliding base. When the seventh sliding base slides a certain distance, the traction rod on the circuit breaker housing will be clamped between the first clamping plate and the second clamping plate. The controller is electrically connected to the fifth hydraulic cylinder.

[0007] Using the above technical solution, when the circuit breaker moves to directly above the first sliding base, the controller controls the first hydraulic cylinder to drive the first sliding base to move vertically upward, so that the circuit breaker enters the range of the first fixed groove. Then, the controller controls the fifth hydraulic cylinder to drive the seventh sliding base to move horizontally, so that the connection between the circuit breaker and the traction rod is clamped by the first clamping plate and the second clamping plate, and then the screw tightening work is completed. This can greatly improve the screw tightening accuracy and prevent skewing during the screw tightening process.

[0008] A further feature of this invention includes a detection device comprising a second connecting frame fixedly connected to the equipment base, an eighth sliding base slidably connected to the second connecting frame, a third clamping plate fixedly connected to the eighth sliding base, a fourth clamping plate fixedly connected to the second connecting frame, a photoelectric sensor connected to the second fixed frame, a ninth sliding base slidably connected to the equipment base, two second top plates fixedly connected to the ninth sliding base, a sixth hydraulic cylinder for driving the eighth sliding base to move horizontally, and a seventh hydraulic cylinder for driving the ninth sliding base to move vertically. The second fixed frame is provided with a second fixing groove located directly above the ninth sliding base. The distance between the two second top plates is adapted to the width of the first conveyor belt. The controller is electrically connected to the sixth hydraulic cylinder, the seventh hydraulic cylinder, and the photoelectric sensor, respectively.

[0009] Using the above technical solution, when the processed circuit breaker moves directly above the ninth sliding base, the controller controls the seventh hydraulic cylinder to drive the ninth sliding base to move vertically upward, so that the second push rod lifts the circuit breaker and places it within the range of the second fixed groove. Then, the sixth hydraulic cylinder drives the eighth sliding base to move horizontally, so that the connection position between the circuit breaker and the traction rod is clamped by the third and fourth clamping plates. Then, the photoelectric sensor sends a photoelectric signal to the screw hole position at this position to detect whether the screw is successfully assembled. If the screw is not tightened properly, the height of the screw end is different, and the photoelectric sensor will send an electrical signal to the controller. The controller controls the first drive motor to stop working, which can ensure the product qualification rate.

[0010] A further feature of this invention is that the rotary motor is equipped with a speed sensor, which is electrically connected to the controller.

[0011] By adopting the above technical solution, since the rotary motor is equipped with a speed sensor, when the number of rotations of the screw-tightening element reaches the threshold, the speed sensor will send an electrical signal to the controller, and the controller will control the rotary motor to stop working. This can ensure that the screw tightness meets the requirements and avoid over-tightening or under-tightening of the screw. Attached Figure Description

When the fourth sliding base 20 slides a certain distance, the screw tightening element 24 and the second electric clamping claw 33 can be located directly above the first sliding base 8.

[0019] First, the circuit breaker to be processed is placed on the first conveyor belt 6. Then, the controller 5 controls the first drive motor 7 to move the first conveyor belt 6 a certain distance. When the circuit breaker moves directly above the first sliding base 8, the controller 5 controls the first hydraulic cylinder 10 to move the first sliding base 8 vertically upward. The two first push rods lift the circuit breaker vertically upward. Then, the controller 5 controls the first rotating vibrating feed plate 27 to move the screw to the first flat vibrating track 26. When the screw moves to the end of the first flat vibrating track 26, the controller 5 controls the stop assembly 29 to be in the open state, and the screw enters the screwing tube 25 for tightening. In the screw element 24, the stop assembly 29 returns to the closed state, and the remaining screw cannot enter the connecting tube 25. At the same time, the connecting rod on the second rotating vibrating plate is transported to its end via the second horizontal vibration track 31. Then, the controller 5 controls the second screw motor 22 to drive the fourth sliding base 20 to move horizontally, so that the second electric clamping claw 33 is directly above the end of the second horizontal vibration track 31. Then, the controller 5 controls the fourth hydraulic cylinder 34 to drive the sixth sliding base 32 to move vertically downward. The second electric clamping claw 33 then clamps the traction rod. Then, the second screw motor 22 and the fourth hydraulic cylinder 34 drive the fourth sliding base 32 to move vertically downward.

Simultaneously, the controller 5 controls the second lead screw motor 22 to move the fourth sliding base 20 horizontally a certain distance, positioning the screw-tightening element 24 directly above the connection between the circuit breaker and the traction rod. Then, the controller 5 controls the third hydraulic cylinder 23 to move the fifth sliding base 21 vertically downwards. The controller 5 then controls the rotary motor 28 to rotate the screw-tightening element 24, completing the traction rod assembly of the circuit breaker. Finally, the controller 5 controls... The first drive motor 7 drives the first conveyor belt 6 to continue moving. The processed circuit breaker moves to directly below the first electric clamping claw 16. Then, the first lead screw motor 17 and the second hydraulic cylinder 18 drive the second sliding base 14 and the third sliding base 15 to move, thereby moving the first electric clamping claw 16 directly above the second conveyor belt 11. The circuit breaker is then placed on the second conveyor belt 11. The controller 5 controls the second drive motor 12 to drive the second conveyor belt 11 to move, thereby completing the unloading of the circuit breaker. Compared with the traditional processing method, this greatly improves the degree of automation and assembly efficiency.

[0020] The equipment base 1 is provided with a first connecting frame 35, a seventh sliding base 36 slidably connected to the first connecting frame 35, a first clamping plate 37 fixedly connected to the seventh sliding base 36, a second clamping plate 38 fixedly connected to the first fixing frame 13, and a fifth hydraulic cylinder 39 for driving the seventh sliding base 36 to move horizontally. The first clamping plate 37 moves towards the second clamping plate 38. The first fixing frame 13 is provided with a first fixing groove 40, which is located directly above the first sliding base 8. When the seventh sliding base 36 slides a certain distance, the traction rod on the circuit breaker housing will be clamped between the first clamping plate 37 and the second clamping plate 38. The controller 5 is electrically connected to the fifth hydraulic cylinder 39.

[0021] When the circuit breaker moves to the top of the first sliding base 8, the controller 5 controls the first hydraulic cylinder 10 to drive the first sliding base 8 to move vertically upward, so that the circuit breaker enters the range of the first fixed groove 40. Then, the controller 5 controls the fifth hydraulic cylinder 39 to drive the seventh sliding base 36 to move horizontally, so that the connection between the circuit breaker and the traction rod is clamped by the first clamping plate 37 and the second clamping plate 38. Then the screw tightening work is completed. This can greatly improve the screw tightening accuracy and prevent the skew phenomenon during the screw tightening process.

[0022] It also includes a detection device 41, which includes a second connecting frame 42 fixedly connected to the equipment base 1, an eighth sliding base 43 slidably connected to the second connecting frame 42, a third clamping plate 44 fixedly connected to the eighth sliding base 43, a fourth clamping plate 45 fixedly connected to the second connecting frame 42, a photoelectric sensor 46 connected to the second fixed frame 19, a ninth sliding base 47 slidably connected to the equipment base 1, two second top plates 48 fixedly connected to the ninth sliding base 47, a sixth hydraulic cylinder 49 for driving the eighth sliding base 43 to move horizontally, and a seventh hydraulic cylinder 50 for driving the ninth sliding base 47 to move vertically.

The distance between the two second top plates 48 is adapted to the width of the first conveyor belt 6. The controller 5 is electrically connected to the sixth hydraulic cylinder 49, the seventh hydraulic cylinder 50, and the photoelectric sensor 46, respectively.

Then, the sixth hydraulic cylinder 49 drives the eighth sliding base 43 to move horizontally, so that the connection position between the circuit breaker and the traction rod is clamped by the third clamping plate 44 and the fourth clamping plate 45. Then, the photoelectric sensor 46 sends a photoelectric signal to the screw hole position at this position to detect whether the screw is successfully assembled. If the screw is not tightened properly, the height of the screw end is different, and the photoelectric sensor 46 will send an electrical signal to the controller 5. The controller 5 controls the first drive motor 7 to stop working, which can ensure the product qualification rate.

[0024] The rotary motor 28 is equipped with a speed sensor 52, which is electrically connected to the controller 5.

[0025] Since the rotary motor 28 is equipped with a speed sensor 52, when the number of rotations of the screw tightening element 24 reaches the threshold, the speed sensor 52 will send an electrical signal to the controller 5, and the controller 5 will control the rotary motor 28 to stop working. This can ensure that the screw tightening meets the requirements and avoid over-tightening or under-tightening of the screw.
