Adopt encapsulating connection structure's long stroke concatenation lathe bed

The utility model discloses an adopt encapsulating connection structure's long stroke concatenation lathe bed and concatenation method, the concatenation lathe bed includes two section at least lathe beds, and adoption hinge system hole bolt location forms through the concatenation of encapsulating connection structure in the junction between the lathe bed, and the rethread fastening bolt fasten, and every section lathe bed wholly adopts welded structure, has reduced the whole weight of lathe bed, the processing degree of difficulty and the transportation degree of difficulty. Lathe bed diagonal bar board and lateral wall board constitute equilateral triangle's stable structure, combine horizontal gusset, make the lathe bed have good static characteristic, two adjacent lathe bed faying faces adopt encapsulating connection structure, have increased the area of contact of faying face, have improved the whole dynamic characteristic of lathe bed, have reduced the perpendicularity requirement of both ends board lateral surface with the guide rail, and then have reduced the processing degree of difficulty and guaranteed the assembly precision. This lathe bed mainly used decides the concatenation lathe bed structure that roof beam moving column aluminum product longmen machining center guaranteed lathe bed rigidity and assembly precision.
