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...
