Background
With the large-scale development of wind power equipment, the size of a planet carrier of a core component of wind power is continuously increased, so that the fine machining of the planet carrier is more and more difficult, and the machining precision and efficiency are limited. The existing processing technical scheme and processing equipment can not meet the finish machining requirements of the large planet carrier.
The existing finish machining process scheme of the large planet carrier comprises the steps of finish turning all sides by a vertical lathe, and finish boring all indexing holes by a floor boring or horizontal machining center. Because the turning and boring are carried out on different machine tools, secondary positioning and clamping are needed, the position accuracy of each surface of the turning and the boring is difficult to control, the auxiliary time is long, and in addition, the geometric accuracy of the boring is difficult to control due to the influence of the dead weight sinking of the boring bar.

The technical scheme includes that a stand column is arranged on a workbench, a beam is driven to move up and down through a Z-axis transmission device on the stand column, a boring and milling cutter rest and a turning cutter rest are respectively driven on the beam through two X-axis transmission devices, a boring cutter or a milling cutter is connected below the boring and milling cutter rest, a rotary cutter tower is connected below the turning cutter rest, and an indexing transmission device is arranged at the bottom of the workbench and drives the workbench and a workpiece clamp to rotate and index.
The left end part of the cross beam is fixedly connected with tool magazine, and one tool magazine is provided with a workpiece measuring head.
The Z-axis transmission device consists of two sets of servo motors and ball screws, the two sets of servo motors and the ball screws are arranged on the left side and the right side of the upright post in parallel, and the two ball screws are connected with the cross beam together.
The number of the ball screws of the X-axis transmission device is two, the ball screws are coaxially and horizontally arranged on the cross beam, the outer side end of each ball screw is connected with a servo motor, the ball screw sliding block of the left X-axis transmission device is connected with a boring and milling tool rest, and the ball screw sliding block of the right X-axis transmission device is connected with a turning tool rest.
The special machine tool for finish machining of the large planet carrier adopts the structure and has the following advantages:
1. The boring and milling tool rest and the turning tool rest do not have ram, and the vertical movement of the boring and milling tool rest and the turning tool rest is realized by the vertical movement of the cross beam, so that the length of the tool rest can be reduced, the turning strength of the tool rest can be increased, and the machining precision of a workpiece can be greatly improved;
2. The application realizes turning and boring combined machining, can greatly improve the position accuracy of a workpiece, reduces the noise of a speed increaser and prolongs the service life;
3. The application realizes one-time clamping of the workpiece, automatically completes turning, boring, drilling and milling, and can improve the efficiency by more than 3 times by adding automatic tool changing and automatic measurement;
4. The workpiece measuring head is arranged, so that the on-line measurement can be realized, the quality is controllable, and the detection efficiency and the reliability are improved;
5. The application can completely replace imported turning and milling composite vertical lathe, saves foreign exchange and reduces manufacturing cost.
