The invention relates to a beam transmission structure for a numerical control milling and drilling machine. A servo motor and a reduction gear installation seat are fixed on a machine frame; the reduction gear installation seat is fixed with a reduction gear; the servo motor is connected with the reduction gear; bearing blocks are fixedly arranged on the machine frame at intervals; a ball screw is rotatably arranged between two bearing blocks; the ball screw between two bearing seats is in threaded connection with a screw seat; one end of the ball screw is connected with an output shaft of the reduction gear through an elastic coupler; the machine frame on one side of the ball screw is fixed with a guide linear guide rail; the guide linear guide rail is parallel to the ball screw; the machine frame at the tail of the guide linear guide rail is fixed with a limit block; the interior of the guide linear guide rail is slidably connected with the guide slide block; and the guide slide block is fixedly connected with the screw seat. The beam transmission structure has high running stability and reliability, can ensure the shape and size accuracy of the drilling and milling surface of a workpiece, and greatly improves the using performance of the machine tool and greatly prolongs the service life of the machine tool.
Description
technical field [0001] The invention relates to a mechanism used on a numerically controlled drilling and milling machine to make a beam seat move longitudinally, in particular to a beam transmission structure of a numerically controlled drilling and milling machine. Background technique [0002] In the prior art, the rigidity, layout, adjustment method, manufacturability and other overall aspects of the transmission structure are not very reasonable. During the transmission process, the positioning accuracy is not high, and the shape and size accuracy of the drilling and milling surface cannot be guaranteed when the workpiece is drilled and milled. , At the same time, it directly affects the performance and life of the machine tool. For CNC drilling and milling machines, the transmission and guidance of the frame transmission structure are the most critical functional components, which directly reflect the accuracy and performance of the equipment.
