2results about How to "Solve rough" patented technology

This application discloses a composite grinding sander, comprising: a housing; a motor disposed within the housing for providing driving force; a drive shaft connected to and driven by the motor; a connecting seat, one end of the drive shaft disposed within the connecting seat; a oscillating grinding disc disposed at the bottom of the connecting seat, having a grinding disc groove at its center, and connected to the drive shaft via an eccentric transmission mechanism, causing the oscillating grinding disc to oscillate when the drive shaft rotates; and a rotating grinding disc disposed within the grinding disc groove, connected to the drive shaft and capable of rotating with the drive shaft. High-speed rotary coarse grinding is achieved through the central rotating grinding disc, resulting in a high material removal rate; and oscillating fine polishing is achieved through the peripheral oscillating grinding disc, resulting in a smooth surface. Both work collaboratively in the same process, solving both the surface roughness problem of traditional rotary coarse grinding machines and the low efficiency problem of traditional oscillating sanders.

The invention discloses an intelligent simulation confrontation system and method based on laser coding and tactile feedback, and belongs to the technical field of electronic games and simulation training. The system is composed of an intelligent simulation gun, intelligent sensing clothes and an internet platform in a cooperative mode, and unification of safety and immersion is achieved through double-laser coding emission (light condensation / light diffusion), dynamic damage judgment, multiple sensory feedback (sound / light / force / electricity) and a state linkage mechanism. The innovation points comprise that the double laser modules are respectively adapted to far / short-range strike; the internet platform supports parameter configuration and state uploading; the dynamic damage algorithm is combined with weapon types, distance attenuation and protection levels; the immersion sense is enhanced through touch electric shock and acousto-optic feedback; and automatic forbidding and array prompting of the gun are realized through Bluetooth / wired linkage. According to the method, the fairness, authenticity and expansibility of simulation confrontation are remarkably improved, and the core contradiction that safety and immersion cannot be achieved at the same time in the prior art is solved.
