Rover Sub-Surface Drill Assembly – Dual-Stage Telescopic Science Module (Lead Screw Mechanism) · 模型 124089
This design presents a compact dual-stage telescopic drilling system intended for autonomous rover-based subsurface core sampling applications, where conventional single-stage linear actuators are limited by stroke length and spatial constraints. The mechanism provides a total vertical travel of up to 800 mm within a compact stowed configuration. It employs a nested dual-box telescopic structure comprising: -Outer structural frame: 160 × 160 × 500 mm aluminum enclosure - Inner telescoping carriage: 120 × 120 × 450 mm sliding stage A triangular load distribution arrangement is implemented to ensure structural rigidity and smooth linear motion under operational loads. One vertex is dedicated to lead screw actuation, while the remaining two vertices are constrained using precision guide shafts and linear bearings to minimize deflection, misalignment, and binding during extension. #Actuation System Primary cutting mechanism: High-torque DC motor directly coupled to a spindle for driving a 350 mm auger drill bit -Linear feed system: Dual motor-driven lead screw configuration for controlled extension and regulated drilling force # Technical Specifications - Maximum vertical travel: 800 mm - Effective drilling depth: approximately 350 mm - Structure: Dual-stage telescopic aluminum frame - Kinematic configuration: Triangular constraint system (lead screw + dual linear guides) for enhanced stability and alignment This assembly is suitable for applications in mars exploration systems, autonomous subsurface sampling platforms, and compact multi-stage linear actuation mechanisms within constrained mechanical environments.
