Abstract
A metal sawing machine of a miniature combined machine tool comprises a sawing machine box and a joint shaft arranged inside the sawing machine box. A rapid saw blade clamping mechanism arranged on the joint shaft is formed by a saw blade clamp body, an elastic device, a fixed rod, a saw blade clamp sliding block, a torsion spring and an opening check ring which are sequentially connected; the fixed rod and the saw blade clamp body are integrated or split; and the saw blade clamp body is in sleeve connection with the joint shaft. When the elastic device is pulled downwards, the saw blade clamp sliding block can move upwards under the action of the torsion spring and achieve the purpose of clamping saw blades. When the rapid saw blade clamping mechanism clamps the saw blades to perform sawing and processing, the saw blade clamp sliding block can be strained because of downward movement of the saw blades, and the saw blades can not be pulled out of the rapid saw blade clamping mechanism because of overlarge pulling force exerted on the saw blades. The metal sawing machine has the advantages of being capable of rapidly clamping and loosening the saw blades, thereby realizing rapid replacement of the saw blades, and being safe and reliable and capable of protecting the saw blades from easy breaking.
