Abstract

The invention relates to a constant-force grinding and polishing tool system and belongs to grinding and polishing tools. The constant-force grinding and polishing tool system comprises a power device, a gear change grinding tool, a damping device, a guide device, a force compensation and detection device and a counter weight device to realize constant-force grinding. A grinding tool head guarantees the gear change grinding tool to move vertically by the aid of the guide device to form a blade normal grinding and polishing force through total weight resultant force of the tool system and a low-friction countercylinder. A tool head normal force is measured and compared with a set value by an S-type sensor, a final value is fed back to a computer, and the low-friction countercylinder is regulated and controlled for force compensation by an electrical appliance proportional valve. The power device insulates vibration influences of a motor vibration source on the tool system by the aid of the damping device, and high-precision force control is realized through feedback of the S-type sensor. The constant-force grinding and polishing tool system has the advantages that the system is novel in structure, constant-force polishing of blade surfaces with different curvatures is realized, surface uniformity is realized, residual stress is diminished, and polishing efficiency is improved.

Description

technical field [0001] The invention relates to a constant force grinding tool system. Background technique [0002] Blades are widely used in axial flow turbines such as steam turbines, turbines, and aeroengines. The surface should meet certain roughness and surface accuracy requirements. Before application, the blades need to be ground and polished. At present, the structural principle of the commonly used grinding tool head system: the method is realized by decoupling the mathematical relationship between the tangential force, normal force, abrasive belt tension, contact wheel wrap angle and cylinder displacement acting on the contact wheel. Constant force control of grinding force. The main disadvantages of this method are: 1. There are many structural links in the decoupling method. The method used in traditional grinding tools is the form of force decoupling, that is, the cylinder is used to push the grinding wheel to generate grinding force. In order to ensure the p...
