Hemisphere shaping fixture of solid wood tellurion and application of hemisphere shaping fixture

The invention provides a hemisphere shaping fixture of a solid wood tellurion. The shaping fixture comprises a worktable, wherein a screw is vertically fixed on the worktable, and the upper end of the screw is positioned at the upper part of the worktable. A hoop is further arranged on the worktable, and the screw is positioned in the center of the hoop. After a plurality of arc sections are buckled and adhered in the hoop, a hemisphere is formed. The upper end of the screw penetrates through the vertex of the hemisphere. A balancing weight sleeves the upper end of the screw and presses the top of the hemisphere. Compared with the prior art, the top end of each arc section is propped agaisnt the screw, and when the balancing weight presses downwards, the circumstance that the arc sections which collapse without of support is avoided. The hoop is positioned in the middle of the last sawn section at the bottom of the hemisphere, when the balancing weight applies pressure to the top of the hemisphere, the bottom of the hemisphere cannot be blown open under the effect of the hoop, and thus, through matching of the hoop, the screw and the balancing weight, shaping of the hemisphere is finished. According to actual situations of the hemisphere, a nut can be adjusted to increase or reduce pressure of the balancing weight on the hemisphere, so that roundness and precision of the hemisphere are guaranteed.
