Abstract

The invention provides a double arm type five spindle head structure and belongs to the field of machine tool manufacturing. The double arm type five spindle head structure comprises a shaft C, a shaft A and a spindle. The shaft C comprises a substrate, a mandrel, a rotating seat, a rotor bush of the shaft C, a first driving motor and a first encoder. An inner rotor of the first driving motor is connected to the rotor bush of the shaft C, the rotor bush of the shaft C is connected to the mandrel, the first encoder is connected to the mandrel, the bottom of the mandrel is connected to the substrate, and the top of the mandrel is connected to the rotating seat; the shaft A comprises a first rotor bush of the shaft A, a second rotor bush of the shaft A, a shaft hole, a second driving motor and a second encoder. A shaft seat is arranged on the inner wall of the shaft hole, an inner rotor of the second driving motor is separately connected to the first rotor bush of the shaft A and the second rotor bush of the shaft A, and the second encoder is connected to the first rotor bush of the shaft A; the substrate is fixedly locked to the top end of the shaft A, the spindle is connected to theshaft seat, and the shaft A, the shaft C and the spindle are coaxially connected. The double arm type five spindle head structure provided by the invention is simple in structure and good in stability, and improves the operating precision and rigidity of a machine tool greatly.

Description

technical field [0001] The invention relates to the field of machine tool manufacturing, in particular to a double-arm five-axis head structure. Background technique [0002] In recent years, five-axis linkage CNC machining centers have been more and more widely used in various fields. In practical applications, whenever people encounter the problem of high-efficiency and high-quality processing of special-shaped complex parts, five-axis linkage technology is undoubtedly an important means to solve such problems. More and more manufacturers tend to look for five-axis equipment to meet high-efficiency and high-quality processing. [0003] The indicators for evaluating the technical performance of machine tools can ultimately be attributed to machining accuracy and production efficiency. Machining accuracy includes the dimensional accuracy, shape accuracy, position accuracy, surface quality and accuracy retention of the machine tool to be processed. Production efficiency in...
