Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a split double-arm five-axis high-speed turntable device. Background Art

[0002] Five-axis machine tools generally add two rotating axes to ordinary three-axis machine tools. Also known as 3+2 axes. Five-axis machine tools can be divided into three categories according to the type of rotating axes: double turntable five-axis, double swing head five-axis, single turntable single swing head five-axis. There are two types of rotating axes: the rotating axis that rotates the spindle direction is called the swing head, and the rotating axis that rotates the worktable that clamps the workpiece is called the turntable. As the core component of the five-axis CNC machine tool: B and C axis turntables, their structure and precision play a key role in the machine tool.

[0003] Currently, the C-axis of the double-arm five-axis rotary table on the market is connected to the B-axis and the tailstock as an integral part, which means that the double-arm five-axis rotary table can only be replaced as a whole when workpieces of different sizes need to be processed. Due to the heavy weight of the rotary table itself, the replacement efficiency of the double-arm five-axis rotary table is reduced. Utility Model Content

[0004] The utility model aims to provide a split double-arm five-axis high-speed turntable device, which can replace the C-axis mechanism in the double-arm five-axis turntable separately and improve the replacement efficiency of the C-axis mechanism.

[0005] To achieve the above purpose, a split double-arm five-axis high-speed turntable device is provided, comprising: a B-axis mechanism, a base, a tailstock mechanism, a C-axis mechanism and a connecting mechanism, wherein the B-axis mechanism and the tailstock mechanism are fixedly connected to the upper end of the base, and the B-axis mechanism and the tailstock mechanism are respectively located at two ends of the base, the rotating shafts in the B-axis mechanism and the tailstock mechanism are opposite, the connecting mechanism is provided with two, and the rotating shafts of the B-axis mechanism and the tailstock mechanism extend to the connecting mechanism respectively, the C-axis mechanism is located between the two connecting mechanisms, and the two side ends of the C-axis mechanism are respectively fixedly connected to the connecting mechanism. The C-axis mechanism in the double-arm five-axis turntable can be replaced separately, and the replacement efficiency of the C-axis mechanism can be improved.

[0006] According to the split double-arm five-axis high-speed turntable device, the connecting mechanism includes a three-jaw chuck, a support plate, a mounting seat, and a fastening bolt. The mounting seat is fixedly connected to the side end of the C-axis mechanism, and the support plate is respectively fixedly connected to the two ends of the mounting seat, and the upper end of the support plate extends to the top of the mounting seat. The side end of the mounting seat is symmetrically provided with two fixing holes. The three-jaw chuck is located at the upper end of the mounting seat, and the clamping ends of the three-jaw chucks in the two connecting mechanisms are far away from each other. A connecting screw hole is opened in the middle of the outer end of the three-jaw chuck, and the connecting screw hole has the same height as the fixing hole. A fastening bolt is installed on the side end of the support plate, and the fastening bolt passes through the fixing hole and the connecting screw hole in turn, and the fastening bolt is threadedly connected to the connecting screw hole. The C-axis mechanism can be quickly installed by clamping the rotating shaft of the B-axis mechanism and the tailstock mechanism with the three-jaw chuck, which has a simple structure and is easy to operate.

[0007] According to the split double-arm five-axis high-speed turntable device, a T-shaped slide groove is provided in the middle of the upper end of the mounting seat, and the slide groove is located between the support plates, a slider is slidably connected in the slide groove, and the upper end of the slider is fixedly connected to the bottom of the three-jaw chuck, which is used to guide the three-jaw chuck and facilitate the movement of the three-jaw chuck.

[0008] According to the split double-arm five-axis high-speed turntable device, the distance between the center points of the two fixing holes is greater than the length of the rotating shafts extended from the B-axis mechanism and the tailstock mechanism, so that the rotating shafts of the B-axis mechanism and the tailstock mechanism are completely away from the three-jaw chuck.

[0010] The above scheme has the beneficial effect of connecting the three-jaw chuck in the connecting mechanism with the rotating shafts of the B-base mechanism and the tailstock mechanism, and sliding the slider in the slide groove to make the rotating shafts of the B-base mechanism and the tailstock mechanism leave the three-jaw chuck, thereby facilitating the disassembly and assembly of the C-axis mechanism and improving the disassembly and assembly efficiency.
