The invention relates to a cooling bed lifting type translation mechanism. The translation mechanism comprises a movable frame, a lifting frame is arranged above the movable frame, a left connecting beam and a right connecting beam are arranged above the lifting frame, a plurality of front translation beams and a plurality of back translation beams are arranged between the left connecting beam andthe right connecting beam, a left guide assembly and a right guide assembly are arranged on the lifting frame, a left roller assembly and a right roller assembly are arranged at the bottom of the left connecting beam and the bottom of the right connecting beam respectively, the left guide assembly and the right guide assembly are matched with the left roller assembly and the right roller assemblyrespectively, and a translation oil cylinder assembly is arranged on the lifting frame and connected with the connecting beams. The multiple front and back translation beams are connected together through the connecting beams, and the piston rod ends of the translation oil cylinders are buckled with the connecting beams through buckling claws, so that the multiple translation beams are driven totranslate synchronously, the tooth jumping phenomenon is avoided, manual adjustment is not needed, the production efficiency is greatly improved, and the service life of equipment is prolonged.
