DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0020] Please refer to the drawings of the embodiments of the present application Figs. 1-2 A turbine end face detection tool comprises:

[0021] The base 1, the micrometer 2, the mold mounting assembly 3 and the micrometer fixing assembly 4, the base 1 comprises a longitudinal plate 10 and a transverse plate 11, the longitudinal plate 10 is fixedly connected to the middle position of the transverse plate 11, wherein the middle position is provided with a mounting through hole 100, and a plurality of threaded holes 12 are arranged on the position symmetrical side wall of the longitudinal plate 10, the mold placing assembly 3 and the micrometer fixing assembly 4 are respectively located on both sides of the mounting through hole 100, and the mold placing assembly 3 and the micrometer fixing assembly 4 are respectively detachably connected with the threaded hole 12, and the micrometer 2 is detachably connected with the micrometer fixing assembly 4.

[0022] The mold mounting assembly 3 and the micrometer fixing assembly 4 located at both ends of the longitudinal plate 10 can be used to fix the micrometer 2 and the mold for detecting the turbine respectively, according to the specification of the turbine, the appropriate mold is replaced, and according to the position of the turbine welding table, the position of the micrometer 2 is adjusted, so that when the turbine is located in the mold, the micrometer 2 contacts the turbine welding table, and then the runout of the micrometer 2 is used to determine whether the turbine welding table meets the standard, it should be noted that the threaded holes 12 located on both sides of the longitudinal plate 10 are not communicated, so as to avoid the interference between the mold mounting assembly 3 and the micrometer fixing assembly 4.

[0023] Specifically, the first annular baffle 101 is arranged in the mounting through hole 100 and close to the side of the micrometer fixing assembly 4.

[0024] Specifically, the thickness of the first annular baffle 101 is less than the thickness of the longitudinal plate 10.

[0025] Considering the installation of the mold mounting assembly 3, the first annular baffle 101 is arranged to ensure that the mold mounting assembly 3 does not interfere with the installation of the micrometer fixing assembly 4, and considering the installation of the mold for detecting the turbine, the boss for installing the mold is reserved by the thickness difference between the first annular baffle 101 and the longitudinal plate 10.

[0026] Specifically, the micrometer fixing assembly 4 comprises a fixed block 40, at least two mounting bolts 41 and a locking screw 42, the fixed block 40 is provided with a micrometer mounting hole 400, a longitudinal locking screw hole 401 and at least two groups of transverse holes 402, one end of the locking screw 42 passes through the longitudinal locking screw hole 401 and is located in the micrometer mounting hole 400, and the mounting bolts 41 pass through the transverse holes 402 and are threadedly connected in the threaded holes 12 respectively.

[0027] The fixing block 40 is fixed by two groups of bolts 41 passing through the transverse holes 402 provided on the fixing block 40 and being screwed into the threaded holes 12 on the longitudinal plate 10. Then, the probe of the micrometer 2 is passed through the micrometer mounting hole 400, and the position of the micrometer 2 is locked by the locking screw 42. The length of the probe of the micrometer 2 is determined according to the mold and the turbine.

[0028] Specifically, the mold mounting assembly 3 comprises an annular mounting disc 30, at least two mounting bolts 31 and a second annular baffle 32. The annular mounting disc 30 is provided with two groups of transverse holes 300. The second annular baffle 32 is fixedly connected to the annular mounting disc 30. The mounting bolts 31 pass through the transverse holes 300 and are screwed into the threaded holes 12.

[0029] Specifically, the second annular baffle 32 is located outside the annular mounting disc 30 near one end of the longitudinal plate 10. A mold placement gap 32 is provided between the second annular baffle 32 away from one end of the longitudinal plate 10 and the side wall of the annular mounting disc 30 away from one end of the longitudinal plate 10.

[0030] The annular mounting disc 30 is fixed by two mounting bolts 31 passing through the transverse holes 300 and being screwed into the threaded holes 12 on the longitudinal plate 10. The annular mounting disc 30 is connected to the longitudinal plate 10 through the second annular baffle 32 located outside the annular mounting disc 30. The part of the second annular baffle 32 located inside the annular mounting disc 30 has a thickness smaller than that of the annular mounting disc 30, thereby forming a mold placement gap 320 for placing the turbine. When the turbine welding table needs to be detected, the turbine end face is placed in the mold placement gap 320. At this time, the probe of the micrometer 2 contacts the turbine welding table. Then, the turbine is rotated. When the turbine welding table has uneven problems, the probe of the micrometer 2 changes under the external force, and the change is fed back to the dial of the micrometer in real time. Therefore, during detection, if the pointer of the dial changes beyond the detection range, it means that the turbine is unqualified. The detection process is fast and simple, and the method does not require workers to have high knowledge, thereby indirectly reducing the cost of manpower and material resources.

[0031] Specifically, the thickness difference between the first annular baffle 101 and the longitudinal plate 10 is the same as the thickness of the second annular baffle 32 located outside the annular mounting disc 30.

[0032] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
