Problems solved by technology

[0002] At present, in the prior art, two fixing devices are used for the detection of the profile of the stator blade and the detection of the journal runout, because the axial direction of the blade and the angular direction of the blade need to be fixed when detecting the profile of the stator blade. The surface sample and the blade back profile surface sample respectively check the profile of the blade pot and the blade back; and the inspection of the blade journal jump needs to fix the axial direction of the blade after the blade can rotate along the axial direction, and use two devices to fix the detection respectively. The repeated workload is large, the errors caused by human factors and other factors are large, the detection efficiency is low, and additional labor costs are increased, which is not suitable for the development trend of blade design, manufacturing, and detection integration.

Embodiment 1

[0014] Example 1, such as figure 1 Shown is a fixing device for stator blade profile and journal runout detection, one side above the base 1 is fixedly connected to the first center seat 2, and the other side is fixedly connected to the second center seat 6, which is arranged on the first center The first apex 5 in the seat 2 is on the same straight line as the second apex 7 arranged on the second apex seat 6, and the action of the handle 15 on the gear 3 is adjusted so that the first spring 4 pushes the first apex 5 along the blade. The axial direction pops up so that the two ends of the blade journal are respectively pressed against the tips of the first center 5 and the second center 7, because the spring force of the first spring 4 is greater than that of the second spring 8 in the second center 7 The relative thrust of the first tip 5 and the second tip 7 fixes both ends of the blade, and the axial positioning surface of the blade is closely attached to the end surface of...

Embodiment 2

[0015] Example 2, such as figure 1 The shown is a fixing device for stator blade profile and journal runout detection. The premise of detecting the blade journal runout is that the blade can rotate freely between the first center 5 and the second center 7. In order to achieve the above purpose , after detecting the size parameters of the blade profile and the intake side and exhaust side, use the screw 13 to pull the angular positioning plate 14 back into the body 12, and then push the screw plug 9 towards the direction of the blade, so that the second top 7 The axial direction of the blade moves so that the angular positioning plate 14 leaves the end surface of the blade edge plate, and the blade rotates freely around the two tops. A platform surface is made on the first top seat 2 and the second top seat 6, and the table seat is placed On the platform surface, screw 16 fixes the measuring instrument on the table seat, and detects the runout of the blade journal through the r...

Abstract

The invention relates to a fixation apparatus for stator blade profile and journal bounce detection. The fixation apparatus comprises a first foot block and a second foot block which are fixed at the two sides of a base; the axial positioning of a blade is finished by clamping a baled axle center by use of two opposite finials in the two foot blocks and attaching an axial positioning plate to a blade axial positioning surface; by use of the attachment of an angle positioning plate in a body seat and a blade profile, the angle positioning of the blade is realized, and the blade profile is further detected; by use of the push effects of the plug screw arranged at the second foot block, the blade is enabled to disengage from the axial positioning plate and rotate on the two finials; and then journal bounce detection is performed on the blade. The fixation apparatus solves the problem of performing blade profile detection and journal bounce detection at the same measuring tool, facilitates one-time multiple dimension clamping and processing on numerical control equipment in terms of process to finish needed detection means, and reduces the labor intensity of repeated positioning.
