Abstract

The invention discloses a lower-hanging-type truss structure based on a quadrilateral mechanism. The lower-hanging-type truss structure comprises a transverse sliding rail, a first driving device is slidably arranged on the transverse sliding rail, and a quadrilateral connecting frame is connected to the first driving device; the bottom of the quadrilateral connecting frame is provided with a second driving device, and a manipulator is connected to the second driving device; the quadrilateral connecting frame is provided with an oil cylinder, the oil cylinder is internally provided with a piston, a first connecting rod and a second connecting rod are arranged on the two sides of the piston, the first connecting rod is connected with the first driving device, and the second connecting rod is connected with the second driving device; a first oil inlet and a first oil outlet are formed in the position, located on one side of the first connecting rod, of the oil cylinder; and a second oilinlet and a second oil outlet are formed in the position, located on one side of the second connecting rod, of the oil cylinder. The lower-hanging-type truss structure based on the quadrilateral mechanism can improve the deficiency of the prior art and improve the positioning efficiency of a horizontal machine tool machining center.

Description

technical field [0001] The invention relates to a machine arm used for a horizontal machine tool machining center, in particular to a lower-hanging truss structure based on a quadrilateral mechanism. Background technique [0002] In the existing horizontal machine tool machining center, the placement of fixtures and workpieces is completed by multi-degree-of-freedom joint robots. When the articulated robot moves rapidly or is impacted by processing, the positioning accuracy of its end will be reduced. Usually, it is necessary to reduce the moving speed and perform repeated positioning to ensure the positioning accuracy of the robot end, and the positioning efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bottom-hanging truss structure based on a quadrilateral mechanism, which can solve the deficiencies of the prior art and improve the positioning efficiency of a horizontal machine tool machini...
