Abstract

The invention discloses a blade-type face measuring device. The face measuring device comprises an installation seat. A clamping and positioning part used for clamping and positioning a blade and a detection part used for detecting whether the profile of the blade is qualified or not are arranged on the installation seat. The clamping and positioning part is arranged on the detection part and is connected with an angle positioning part used for positioning angles of the blade. The angle positioning part is arranged on the clamping and positioning part. The clamping and positioning part comprises a clamp head shaft used for clamping a positioning shaft to be laminated on a positioning end face, and a locking piece used for allowing the clamp head shaft to lock a positioning shaft. The locking piece is arranged on the clamp head shaft so as to provide circumferential clamping force for the clamp head shaft. According to the invention, a positioning problem that the tip of the current profile measuring tool fails to touch a technique hole of the blade or the blade has no technique hole, a blade rebound deformation problem caused by supporting of the tip and an inconsistent standard problem can be solved and positioning precision is quite high.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a blade profile measuring device. Background technique [0002] Attached picture figure 1 and figure 2 As a blade part, it is necessary to design a profile measuring tool to measure the profile on the section of the blade 1 with a fixed distance from the positioning end surface 101 on the blade 1 (such as figure 1 Ⅰ, Ⅱ ~ Ⅶ cross-section) is qualified. [0003] Existing surface measuring tools such as image 3 As shown, the right end of the blade 1 in the horizontal direction is centered through the cooperation of the inner hole of the positioning sleeve and the positioning shaft 102 of the blade 1, and the left end opposite to the right end uses a movable tip to support the process hole 104 on the blade, and through The spring generates a force toward the right, and the blade is pressed against the top, so that the positioning end surface 101 on the blade 1 is close to the end su...
