Missile heat shield turning and grinding compound machine tool

Abstract

The invention relates to a turning, grinding and compositing machine tool for large thin-walled conical structures such as missile heat-proof sleeves and belongs to the field of machine manufacturing. A workpiece and a clamp are absorbed by a vacuum pump to form vacuum, so that a conical sleeve and a heat-proof sleeve are tightly combined, and the heat-proof sleeve is clamped and positioned by clamping the conical sleeve. Turning of the heat-proof sleeve and grinding wheel polishing are achieved through a turning tool. An angle grinder clamps and occupies one station of a four-station tool holder and moves along the axial direction of the heat-proof sleeve to achieve symmetrical subdivision of the heat-proof sleeve. Switching of the functions of turning and symmetrical subdivision is achieved through cutter head rotation. A grinding tool holder is located opposite to the turning tool holder. The grinding tool holder moves to drive a grinding wheel to grind the heat-proof sleeve precisely. The turning, grinding and compositing machine tool integrates multiple functions such as fast clamping, turning, grinding, symmetrical subdivision and grinding wheel polishing, multiple machining procedures such as turning and grinding of the heat-proof sleeve is achieved through one-step clamping, machining speed is increased, and errors brought by multiple times of station switching are reduced.

Description

technical field [0001] The invention relates to a compound machine tool for a tapered thin-walled rotary part, in particular to a turning-grinding compound machine tool for a missile heat-proof sleeve, which belongs to the field of mechanical manufacturing. [0002] technical background [0003] The heat shield is the protective structure of the missile nose cone, which protects the titanium alloy frame from high-speed airflow, blocks external aerodynamic friction heat, and provides a suitable working environment for the missile. At present, the heat shield used in the production of missiles is a composite material component with a conical rotary structure. During the implementation of the thin-walled conical part turning process, the clamping is cumbersome, and the auxiliary time for tool setting, measurement, and adjustment is long. Production The efficiency is low, which cannot meet the requirements of mass production, and because the wall thickness of this thin-walled con...

Problems solved by technology

The station change between turning, grinding and symmetrical splitting leads to an increase in the clamping error and increases the clamping time

And because the accuracy in production depends on the proficiency of manual operation, the product processing is highly dependent on the technical level of workers, and the production efficiency is low.
