What is the function of knife plate holes in the construction machinery industry? — Core Functional Classification

Positioning and Assembly

Function: Enables precise component positioning and bolted connections through standard holes (e.g., through holes, threaded holes), ensuring assembly accuracy.

Applications: Examples include excavator bucket tooth mounting holes and hydraulic cylinder installation holes.

Weight Reduction and Structural Optimization

Function: Reduce weight through stepped holes and irregular holes (e.g., square holes) while maintaining structural strength.

Applications: Lightweight designs in construction machinery arms.

Functional Passages

Function: Serve as channels for hydraulic oil lines, coolant, or cables (e.g., blind holes, deep holes).

Applications: Internal oil passages in hydraulic valve blocks, sensor routing holes.

Process Aids

Function: Counterbores (round/square) distribute fastener stress; countersinks improve contact surface flatness.

Application: Countersunk holes for high-strength bolt connections.
