Abstract

The invention discloses a horizontal type six-shaft parallel-serial computer numerical control milling machine, and relates to machining tools for large workpieces with complex curved surfaces. The horizontal type six-shaft parallel-serial computer numerical control milling machine is provided with a base, and a Y-direction slide platform, a Z-direction slide platform and an X-direction slide platform are mounted on the base through rails in sequence. A Y-direction drive motor is arranged on the base, and the Y-direction drive motor is connected with a Y-direction drive screw rod and drives the Y-direction slide platform to move in the Y direction. A Z-direction drive motor is arranged on the Y-direction slide platform, and the Z-direction drive motor is connected with a Z-direction drive screw rod and drives the Z-direction slide platform to move in the Z direction. An X-direction drive motor is arranged on the Z-direction slide platform, and the X-direction drive motor is connected with an X-direction drive screw rod and drives the X-direction slide platform to move in the X direction. An RPS parallel mechanism with three degrees of freedom is arranged on the X-direction slide platform, and a machining tool is mounted at the executing end of the parallel mechanism. The horizontal type six-shaft parallel-serial computer numerical control milling machine has the advantages of being large in working space, good in stiffness property, low in cost and high in machining accuracy. Further, the horizontal type six-shaft parallel-serial computer numerical control milling machine can be used for large stroke machining in the Y direction.

Description

technical field [0001] The invention relates to a processing tool for a large complex curved surface workpiece, in detail it is a horizontal 6-axis mixed-connection numerical control milling machine with good rigidity performance and large working space. Background technique [0002] The processing of complex free-form surface workpieces requires a 5-coordinate machining center, and the tool can realize 3 movements and 2 rotations. At this stage, this type of processing device is mainly divided into two types: serial processing center and parallel processing center. In the tandem machining center, the tool is located at the end of the tandem kinematic chain, and the processing space is large, but the error transmission chain is long, and the machining accuracy is low; in order to improve the rigidity performance of the device, a huge machine body is required and the cost is high. At present, tandem processing devices are widely used. In the parallel machining center, the t...
