A Design Method for Lifting Hole of Vertical Machine Tool

Abstract

The invention discloses a method for designing lifting holes of a vertical machine tool. The method comprises the following steps: 1) determining center of gravity of the vertical machine tool, a body and a base; and 2) designing the lifting holes, namely a) drawing vertical center lines A1, A2 and A3 perpendicular to the ground and horizontal center lines B1, B2 and B3 parallel to the ground by virtue of the center of gravity of the vertical machine tool, the body and the base according to a lifting manner that a long side of equipment is parallel to the ground and a short side of the equipment is perpendicular to the ground; b) respectively forming a first lifting hole and a second lifting hole in one side, which is far away from the center of gravity of the vertical machine tool, of the body and the base; c) forming a third lifting hole in the other side of the body, so that the distance between the first lifting hole and the center of gravity of the body is approximately equal to that between the third lifting hole and the center of gravity of the body; and d) forming a fourth lifting hole in the other side of the body, so that the distance between the second lifting hole and the center of gravity of the base is approximately equal to the that between the fourth lifting hole and the center of gravity of the base. According to the method for designing lifting holes of the vertical machine tool, the center of gravity of an irregular object is accurately and rapidly determined by adopting professional design software, and the lifting holes of irregular objects such as the vertical machine tool and the like are reasonably designed; and moreover, the method is simple in design and convenient to use, the vertical machine tool can be hoisted in a balanced state while lifting, and turnover during lifting is avoided.

Description

technical field [0001] The invention relates to the field of mechanical hoisting, in particular to a design method for a hoisting hole of a vertical machine tool. Background technique [0002] Generally, there are four lifting holes on the object to be hoisted, which are respectively arranged on two parallel rods, and when the lifting holes are provided, the four lifting holes are often rectangular and symmetrically distributed on the two rods. When hoisting regular objects, this structure can ensure that the hoisting center of the four lifting holes is located at the center of gravity of the object to be hoisted, and the object to be hoisted can be hoisted smoothly. However, when hoisting irregular objects, the center of gravity of the object to be hoisted is often not at the hoisting center of the four lifting holes. The assembly work of the components assembled in the air brings great inconvenience and has potential safety hazards. [0003] At present, the methods for d...

Problems solved by technology

Traditionally, the determination of the center of gravity of irregular objects such as vertical machine tools can only be done by combining on-site experience or through strict calculation of the weight of heavy objects. The traditional method is cumbersome and not necessarily accurate.
