Description
Technical Field
The utility model relates to the field of wind power gear box machining tools, in particular to a height-adjustable machining tool for a torque arm inclined oil return hole of a wind power gear box.
Background
Wind power is used as a high-efficiency, safe and renewable clean energy source. At present, the effect of clean energy is more and more important, and corresponding development force is increased in most countries. Up to now, wind power generation has been developed for a long time, and has been generally adopted in China. The installation quantity of the wind generating set is in an explosion period, so that the processing quality and the efficiency of a core component gearbox inside the wind generating set are important.
The wind power gear box mainly comprises a box body, a torque arm, a gear, a planet carrier, a bearing, a standard component, an electric element and the like, wherein the torque arm is one of main components of the planetary gear transmission device, and the wind power gear box is fixedly connected with the engine room through the torque arm; because wind-powered electricity generation gear box's model is various, therefore the torque arm model that the gear box used also has the difference. In order to prevent oil leakage at the torque arm installation cover plate of the gearbox due to excessive oil quantity, oil return holes are usually required to be machined at the position, close to the lower side, of the torque arm installation cover plate, all the oil return holes are communicated from the end face of the torque arm installation cover plate to the inner cavity of the gearbox, the oil return holes above the torque arm are perpendicular to the installation face of the cover plate, and the oil return holes can be directly machined above a conventional vertical machining center. However, due to design requirements, some types of oil return holes have certain angle requirements relative to the mounting surface of the torque arm cover plate, and the inclined oil return holes with the angle requirements are often time-consuming and labor-consuming to process.
The technical scheme in the first prior art is as follows:
generally, when the inclined oil return holes with a certain angle are formed on the torque arm, the inclined oil return holes with different types are different in inclination angle relative to the cover plate mounting surface, so that the height of the tool to be lifted is calculated according to the inclination angles of the inclined oil return holes with different types and the maximum excircle diameter of the torque arm. The inclined angle of the heightened torque arm is ensured to be consistent with the angle of the torque arm inclined oil return hole to be processed. Therefore, one side of the torque arm needs to be supported, the other side needs to be raised by using equal-height blocks, and the heights of the raised blocks used by the torque arm are changed according to the inclination angles of the torque arm inclined oil return holes of different types and the change of the maximum excircle of the torque arm.
Drawbacks of the first prior art:
1. the fixed-height heightening blocks are used, different types of torque arms are needed, and as the inclination angle of the inclined oil return hole is different from the maximum excircle of the torque arm, various heightening blocks with different heights are needed to be manufactured, and the tooling cost is additionally increased;
2. the workpiece needs to be corrected before the part is machined, and the lifting block with fixed height is time-consuming and labor-consuming to adjust, so that the efficiency is low.
The technical scheme of the second prior art is as follows:
1. the torque arm is not required to be heightened, and the torque arm is directly processed through the vertical processing center with the side milling head module. And the angle deviated by the side milling head of the machine tool is adjusted to be consistent with the inclination angle of the inclined oil return hole to be processed, so that the machine tool can process.
Drawbacks of the second prior art:
1. not all vertical machining centers are provided with head side milling head modules, and the requirements on hardware facilities of a machine tool are high. The side milling head of the machine tool is relatively expensive, and the purchasing cost of the machine tool is additionally increased;
2. the installation of the side milling head needs to be manually installed, and after the through holes and threaded holes perpendicular to the end faces of the torque arms are machined, the side milling head and the cutter are required to be installed, so that time and labor are consumed.
