Quick check of inner spherical parts

In the automotive and machinery industry, there are a large number of housing parts with the inner spherical surface as the main size. Therefore, it is difficult to quickly, accurately and quantitatively detect the position of the ball diameter and the center of the ball with respect to the reference surface. As shown in Fig. 1, the spherical case diameter of the differential case is known as S (?) 148 mm, and the center of the ball is opposite to the reference surface (B side).

Solar Light

Due to the limited and uneven distribution of energy, most countries in the world have insufficient supply and cannot meet the needs of economic development. Therefore, the development of new energy has become a top priority. Solar energy is an inexhaustible and inexhaustible renewable energy source for human beings. At present, my country has also issued some relevant policies and vigorously supports the development of new solar energy sources. More and more solar energy equipment is used in the market, and solar lights are among them One kind.
