Problems solved by technology
Since the energy storage hole of the ratchet frame is located on the curved surface, the ratchet frame cannot be drilled on the curved surface without the aid of a jig
However, the existing fixture cannot accurately realize the accurate positioning of the energy storage hole, which affects the processing quality and processing efficiency of the ratchet frame, and cannot meet the actual requirements.

The invention provides a drilling tool for a ratchet rack of a circuit breaker, which is applied to the technical field of circuit breakers. A concave ratchet rack placing groove (2) is formed in a base (1) of the drilling tool for the ratchet rack of the circuit breaker; a ratchet rack positioning hole I (3) and a ratchet rack positioning hole II (4) are formed in the side of the base (1); a ratchet positioning screw hole (18) is formed in the side of the base (1); a ratchet positioning bolt (5) is screwed in the ratchet positioning screw hole (18); the drilling tool further comprises a limiting shaft I (19) and a limiting shaft II (20); a guiding component (6) is arranged at the upper part of the base (1); a drilling guiding hole (7) is formed in the guiding component (6); and the guiding component (6) is positioned above the ratchet rack placing groove (2). The drilling tool can position a ratchet rack body conveniently and quickly, realizes positioning and drilling of an energy storing hole quickly and accurately, and improves the processing quality and the processing efficiency of the ratchet rack.
Description
technical field [0001] The invention belongs to the technical field of circuit breakers, and more specifically relates to a drilling tool for a ratchet frame of a circuit breaker. Background technique [0002] The ratchet frame is an important part of the vacuum circuit breaker used to store energy for the closing spring. Its function determines that it must drill a round hole (energy storage hole) on the side of a curved surface structure for inserting the energy storage rod. , by shaking the energy storage rod up and down, it is used to store energy for the closing spring of the circuit breaker. Since the energy storage hole of the ratchet frame is located on the curved surface, the ratchet frame cannot be drilled on the curved surface without the aid of a clamp. However, the existing fixture cannot accurately realize the accurate positioning of the energy storage hole, affects the processing quality and processing efficiency of the ratchet frame, and cannot meet the actu...
