Dual-positioning protective door of numerically-controlled machine tool for cutting stone
The invention discloses a dual-positioning protective door of a numerically-controlled machine tool for cutting stone. The protective door comprises T-shaped support risers and a protective door body, wherein the T-shaped support risers are installed on upright posts at two ends of the machine tool; roller mounting grooves are formed in the upper and lower ends of the T-shaped support risers; a plurality of rollers are mounted in the roller mounting grooves; elastic shaft sleeves are mounted on the support shafts of the rollers; the protective door body is mounted on the T-shaped support risers; roller paths are arranged at the upper and lower ends of the protective door body; the roller paths can slide on the rollers; and the rollers can roll in the upper and lower roller paths to achieve double positioning. Therefore, the positioning accuracy and moving reliability are guaranteed, and the potential safety hazard of shaking back and forth because the distance between a left support riser and a right support riser is relatively large is avoided; and the protective door is low in cost and easy to maintain.
