[0032] The utility model provides a circuit breaker rivet dismounting tool.

[0033] In the embodiment, referring to Figures 1-5 The circuit breaker rivet dismounting tool comprises:

[0034] The bracket 1 is provided with a positioning mechanism on the bottom plate 11 for positioning the circuit breaker 2 on the bottom plate and a rivet ejection hole 3 for rivet ejection, the number and position of the rivet ejection hole 3 corresponding to the rivet holes on the circuit breaker 2;

[0035] The top pin assembly includes a lower bottom plate 4, a guide column 5 fixed on the lower bottom plate 4, an upper bottom plate 22 slidingly arranged on the guide column 5, a needle plate 6 fixed on the upper bottom plate 22, a limiting block 7 fixed on the top of the guide column, a top pin 8 fixed on the bottom of the needle plate, and a connecting plate 9 fixed on the upper bottom plate, the top pin passing through the needle hole 23 of the upper bottom plate and the lower bottom plate, the number and position of the top pin corresponding to the rivet holes on the circuit breaker;

[0036] The lifting power mechanism 10 is fixed on the top plate of the bracket, the output end of the lifting power mechanism is connected with the connecting plate, and the lifting power mechanism provides power for the up-down reciprocating movement of the top pin assembly.

[0037] The bracket of the present application is used to fix the circuit breaker, and the top pin assembly composed of the lower bottom plate, the guide column, the needle plate, the limiting block, the top pin and the connecting plate is used to eject the rivet. The number and position of the top pin correspond to the rivet holes on the circuit breaker, ensuring that the rivet can be ejected accurately each time. The lifting power mechanism is responsible for driving the top pin assembly to move up and down reciprocatingly, thereby realizing the disassembly of the rivet.

[0038] The present application can disassemble multiple rivets on the circuit breaker at one time, greatly improving the disassembly efficiency and reducing the labor cost.

[0039] Specific use method: the circuit breaker to be disassembled is placed on the bottom plate through the positioning mechanism, then the top pin assembly is driven to press down by the lifting power mechanism (such as a pneumatic cylinder), after the lower bottom plate is pressed on the circuit breaker, the needle plate provided with the top pin continues to press down, and finally the rivet on the shell of the circuit breaker is ejected from the ejection hole by the top pin.

[0040] Specifically, the bracket includes a bottom plate 11, a back plate 12 fixed on the bottom plate 11, a side plate 13 fixed on the bottom plate, and a top plate 14 fixed on the back plate and the side plate, and a reinforcing plate 15 is arranged between the bottom plate and the back plate.

[0041] In order to increase the structural stability of the whole tooling, the bracket is designed as a frame structure including the bottom plate, the back plate, the side plate and the top plate, and the whole is a box structure with one side open, and a reinforcing plate is arranged between the bottom plate and the back plate to enhance the overall rigidity. This structure design not only enhances the carrying capacity of the bracket, but also effectively prevents the tooling from deforming during use, thereby ensuring the stability and reliability of the tooling.

[0042] Specifically, the lifting power mechanism is a pneumatic cylinder or an electric cylinder.

[0043] The gas cylinder or electric cylinder is used as the power source, which can be selected flexibly according to actual needs, guarantees sufficient driving force, is convenient for maintenance and adjustment, and is convenient for users to select the most suitable power form according to the site conditions.

[0045] The front positioning block, the rear positioning block and the side positioning blocks are designed to enclose a positioning area together, which is used for accurately placing and fixing the circuit breaker. Such a positioning mechanism can ensure that the circuit breaker is firmly fixed at the specified position, prevents deviation during disassembly, and ensures the smooth progress of the disassembly work.

[0046] Specifically, the height of the front positioning block is lower than that of the rear positioning block and the side positioning blocks.

[0047] In order to facilitate the placement and removal of the circuit breaker, the height of the front positioning block is designed to be lower than that of the rear positioning block and the side positioning blocks. Such a design can facilitate the placement or removal of the circuit breaker by the operator, improve the convenience of use, and reduce the risk of bumps during operation.

[0048] Specifically, the bottom of the lower bottom plate is provided with a rear pressing block 19 and a side pressing block 20.

[0049] The rear pressing block and the side pressing block are added to the bottom of the lower bottom plate, which leaves a gap between the circuit breaker and the lower bottom plate, and further stabilizes the position of the circuit breaker, so that the circuit breaker is more stable during disassembly and displacement caused by vibration or other external forces is reduced.

[0050] Specifically, the connecting plate is slidably connected with the back plate through a slide rail and slide block assembly 21.

[0051] The slide rail and slide block assembly is adopted between the connecting plate and the back plate to ensure that the connecting plate and the top nail assembly connected therewith run stably during lifting.
