Abstract

The invention discloses a self-adaptive angle accurate positioning and clamping device for an adjustable blade. The self-adaptive angle accurate positioning and clamping device comprises a puller bolt (1), a clamp body (2), a bracket (3), a small-end positioning block (7), a large-end positioning block (8) and an orientator (11), wherein the puller bolt (1) is fixed to the lower left portion of the clamp body (2) through interference fit of a positioning pin and a compression screw; the upper end of the puller bolt (1) is connected with the bracket (3); the small-end positioning block (7) is arranged at the upper end of the bracket (3); the large-end positioning block (8) is arranged on the upper left portion of the clamp body (2); the orientator (11) is arranged on the upper right portion of the clamp body (2), and a orienting chuck (10) horizontally moves and circumferentially rotates under the action of a spring (12) and is matched with the small-end positioning block (7) and the large-end positioning block (8) to automatically determine the position of the blade. The orienting chuck (10) of the device adopts a symmetrical V-shaped structure, can adapt to the thickness change of a blade profile and the deformation of the blade profile, and can realize accurate positioning through the orientator.

Description

technical field [0001] The invention relates to the field of clamping and positioning technology, in particular to an adjustable blade self-adaptive angle precise positioning clamping device. Background technique [0002] Aviation blades are a very important type of aero-engine parts. The shape of the blade is often a complex and irregular surface, and its precision requirements are relatively high, so higher requirements are put forward for its clamping and measurement. At present, a three-coordinate measuring machine is commonly used to measure it, and the aviation blade is placed on the three-coordinate measuring machine. on the measurement platform. However, the three-coordinate measuring machine has strict requirements on the detection environment, and requires professionals to operate, the detection efficiency is low, and the detection cost is high. [0003] In the utility model patent application document with the application number CN201920421243.0, a clamp for cla...
