一般机床是安装在普通基础上,用地脚螺钉把床身、可调垫铁和混凝土联结在一起的。这种基础对于一般机床来说,其精度是可以保证的,但对于大型精密机床、特别是导轨磨床,就显得刚性不足,影响安装精度。因此,肇庆市机械厂在安装四米单臂导轨磨床时,采用了另一种基础——刚性基础。下面对两种基础作一些分析比较,并对刚性基础的结构和安装工艺作简单的介绍。 (1) 普通基础的缺点若干套可调垫铁安放在作为基础的混凝土表面上,由于水泥面不可能是平整的,因
General machine is installed on an ordinary basis, with the ground screw to the bed, adjustable horn and concrete together. This basis for the general machine, its accuracy can be guaranteed, but for large-scale precision machine tools, especially the rail grinder, it appears insufficient rigidity, affecting the installation accuracy. Therefore, Zhaoqing Machinery Factory in the installation of four-meter single-arm rail grinder, using another foundation - the rigid foundation. The following two basics for some analysis and comparison, and rigid foundation of the structure and installation process for a brief introduction. (1) the shortcomings of ordinary basis A number of sets of adjustable horn placed on the concrete surface as a basis, because the cement surface can not be smooth, due to
