Problems solved by technology
[0003] The purpose of the present invention is to provide a coating thickness measuring device and method for blade tenon, which solves the problem that the coating of dovetail blade tenon cannot be detected by general measuring tools. The comparison measurement of the blade under test, or the comparison measurement of the tested blade and the standard sample, can intuitively display the coating thickness of the tenon on the reading table, and obtain the result. At the same time, the measurement process is simple and easy to operate, which reduces the detection cost and can effectively improve the detection efficiency. efficiency

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] Such as Figure 1 to Figure 3 As shown, a blade tenon coating thickness measuring device includes a base plate 1, a screw II14, a support I2, a Z-shaped support II6 and a base 7 with a boss, and the upper surface of the base plate 1 is installed by bolts There are support I2 and base 7, and the center line of symmetry of support I2 is coplanar with the center line of symmetry of base 7. The base 7 is provided with support II6, and the horizontal part of the lower part of support II6 is in the same plane as base 7. Through bolt connection, the side wall of the upper horizontal part of the support II6 is provided with a horizontal V-shaped groove on the side close to the support I2, and a positioning rod 5 is installed in the V-shaped groove, and the other end of the upper horizontal part of the support II6 is opened. There is a counters...

The invention discloses a blade tenon coating layer thickness measuring device and a use method thereof. The blade tenon coating layer thickness measuring device comprises a bottom plate; a support I and a base are mounted on the upper surface of the bottom plate, a support II is arranged on the base, and a positioning rod is mounted in a V-shaped groove of the support II and is fixed through a screw II; a reading meter is mounted in a meter clamping hole of the support I and is tightly jacked through a set screw; a lever is rotatably mounted in a rectangular groove of the support I, and the end face of the lever makes contact with a measuring head of the reading meter; and a horizontal hole located under the meter clamping hole is formed in the support I, a screw I is arranged in the horizontal hole, a nut of the screw I is in threaded connection with an inner hole of the horizontal hole, a screw rod of the screw I penetrates through a kidney-shaped hole in the first end of the lever, the tail end of the screw I is in threaded connection with a nut, and a spring sleeves the screw rod part of the screw I between the nut of the screw I and the end face of the first end of the lever. Through the measuring device, the coating layer thickness of a tenon can be visually displayed on the reading meter, the operation is simple and easy, the detection cost is low, and the detection efficiency can be effectively improved.
Description
technical field [0001] The invention belongs to the technical field of measurement of machined parts, and in particular relates to a blade tenon coating thickness measurement device and a use method. Background technique [0002] The tenon of the rotor blade of an aero-engine is generally dovetail-shaped. After machining, both sides need to be sprayed with a protective coating. The final size of the tenon is the actual size after coating, so there are strict requirements on the thickness of the coating. The thickness of the coating is very thin, generally only about 0.1mm, and it is attached to the inclined surface of the tenon. General measuring tools such as calipers and micrometers cannot be measured, so a special measuring device is needed to detect the actual coating thickness. Contents of the invention [0003] The purpose of the present invention is to provide a coating thickness measuring device and method for blade tenon, which solves the problem that the coating ...
