Problems solved by technology

[0002] After the current engine blades have been working for a certain period of time, under the influence of various external stresses, the blade body will have different torsional deformations to a certain extent. When the engine is overhauled, the blade shape of the blade needs to be corrected. The traditional Calibration methods such as beating, thermal shaping, etc. are difficult to accurately grasp the angle of blade shaping, and the consistency of blade shaping is also difficult to guarantee; it cannot provide data judgment basis for subsequent blade shaping of the same type

Abstract

The invention discloses a tool clamp specially for shape correction of a blade. The clamp comprises a base plate, a positioning block, a baffle, a cross beam, a torque transmission sleeve, a jacking rod, a turbine, a transmission shaft, a handle and the like. The blade is arranged on the positioning block and connected with the torque transmission sleeve together. During shape correction, the handle is rotated, and the handle and a worm shaft are fixed together through a square groove to move. The worm shaft transmits force to the turbine and drives the torque transmission sleeve to rotate. The torque transmission sleeve and a blade sawtooth crown are located and connected together, a blade body is driven to rotate under the effect of the force, and then the goal of shape correction is achieved. In the operation process, through real-time detection of a detection instrument, it is guaranteed that the blade body is corrected and rotated to a theoretical position. According to the tool clamp, by adopting the characteristics of a worm and gear transmission mechanism and key connection, the technical problem of inaccurate and uncontrollable shape correction in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of blade clamps, in particular to a special tooling clamp for blade shape correction. Background technique [0002] After the current engine blades have been working for a certain period of time, under the influence of various external stresses, the blade body will have different torsional deformations to a certain extent. When the engine is overhauled, the blade shape of the blade needs to be corrected. The traditional Calibration methods such as beating, thermal shaping, etc. are difficult to accurately grasp the angle of blade shaping, and the consistency of blade shaping is also difficult to guarantee; it cannot provide data basis for subsequent blade shaping of the same type. Contents of the invention [0003] In order to solve the above technical problems, a special tooling fixture for blade shape correction is proposed. The specific technical scheme is as follows: [0004] A special tooling fixture...
