The utility model provides a compartment bottom plate hole drilling positioner, which belongs to mechanical processing auxiliary equipment and relates to a hole drilling positioning device. The compartment bottom plate hole drilling positioner is characterized by being formed by connecting an arch-shaped support frame, a positioning pin and a punching and curving mechanism, wherein an upper wing of the arch-shaped support frame is provided with the punching and curving mechanism provided with an anvil, a lower wing of the arch-shaped support frame is provided with the positioning pin, and the center axial line of an anvil head and the center axial line of the positioning pin are positioned on the same plumb line. The compartment bottom plate hole drilling positioner has the advantages that the design is novel, the structure is simple, compact and reasonable, when the drilling positioner is adopted, multi-person multi-work-procedure operations such as batten processing, hole distance measuring by battens, wire pulling and wire snapping, hole distance measuring by the battens and one-by-one sample making and hole punching are omitted, the operation is simple and convenient, rivet hole sample punching holes can be accurately and easily punched in side beam bottom plates at the two sides by one person in one step, in addition, each hole uses a corresponding bottom beam rivet hole as the reference, the error caused by reference conversion is avoided, the line scratching precision of the bottom plate rivet hole is greatly improved, the work intensity of workers and the maintenance cost are reduced, the work efficiency and the maintenance quality are improved, safety and reliability are realized, and the potential safety hazard is eliminated.
