[0004] The CNC vertical lathe is a platform that drives the workpiece to rotate. The cutter head can be programmed to perform XY translation and up and down precession, but has no rotation function. Although it is widely used and the cost is low, it cannot be directly used for the above thin Machining of Shell Members

Embodiment Construction
[0024] Below in conjunction with accompanying drawing, this processing device and method are described in further detail:
[0025] figure 1 The above only shows the size of the workpiece to be processed, the hole diameter is only about 1 mm, and the thickness of the processed thin shell member is only about 0.05 mm. There is no specific requirement for the speed of the high-speed rotating electric grinding head, and it can be 1000, 3000 or even 10000 revolutions per minute, which can evenly grind the ring-shaped processing surface and the stepped processing surface. Such as figure 2 , image 3 , Figure 4 As shown, the processing device and method refer to: electric grinding head 4, grinding wheel 5, transfer positioning block 3, compression screw 1, fastening bolt 2, positioning fixture 6, workpiece 7 to be processed; The grinding head 4 is installed on the tool holder of the CNC vertical lathe as the main force of the grinding process. The tool holder originally has no ...

A processing device for CNC vertical milling of honeycomb parts of aero-engines, which is composed of an electric grinding head, a grinding wheel, a transfer positioning block, a compression screw, a fastening bolt, and a positioning fixture; the upper end of the transfer positioning block is positioned by the compression screw On the tool holder of CNC vertical lathe, the electric grinding head is connected with the lower end of the transfer positioning block through fastening bolts. There is a circular inner hole in the middle of the transfer positioning block. The fan-shaped grooves are formed on the side, and the fan-shaped grooves on both sides can be used as lifting grooves, which are convenient for handling and ensure the safety of operators; the grinding wheel is assembled on the main shaft of the electric grinding head, and only the grinding wheel needs to be trimmed when processing the cylindrical inner arc surface of the annular honeycomb part Outer circle surface; when processing the stepped inner arc surface of annular honeycomb parts, the outer circle surface and end surface of the grinding wheel can be trimmed to ensure the accuracy requirements of the honeycomb radial and axial dimensions at the same time.
Description
technical field [0001] The invention relates to a processing device and method for aero-engine honeycomb parts, in particular to a processing device and method for aero-engine honeycomb parts numerically controlled vertical milling. Background technique [0002] The annular honeycomb part of the aero-engine is a special air-sealing part used in the engine. This part not only has good sealing characteristics, but also has good rotor dynamics characteristics. The annular air seal with honeycomb structure can effectively restrain the gas flow in the rotor-stator gap. It requires high precision and can withstand high temperature, thereby reducing air leakage loss and improving the efficiency of aero-engines. In the event of rubbing between moving and static parts, since the honeycomb parts are designed to have a wall thickness of only about 0.05mm, the honeycomb parts will be worn first. The use of ring-shaped honeycomb parts can effectively reduce rotor vibration and ensure the...
