Abstract
The invention discloses a M1C-2 main bearing rivet hole position gauge comprising a main body. The central position of the main body is provided with a second fixing hole position. The left side of the second fixing hole position is provided with a first fixing hole position, and the right side of the second fixing hole position is provided with a third fixing hole position. The inner part of the first fixing hole position is correspondingly provided with a prismatic pin, and the inner part of the second fixing hole position is correspondingly provided with a reference shaft. The inner part of the third fixing hole position is correspondingly provided with a rivet pin, and the upper surface of the main body is provided with a positioning through hole. The M1C-2 main bearing rivet hole position gauge is advantageous in that the accurate three-point positioning can be completed by adopting the cooperation of the reference shaft and the two positioning through holes, and whether the position of the rivet hole of the main bearing meets the requirement can be determined according to the position relation between the prismatic pin and the rivet pin; the measurement accuracy is higher, and the stable guarantee can be provided for the processing and the use; the use and the carrying can be more convenient, and the large-scale popularization and use can be facilitated.
Description
Technical field
The present invention relates to rivet hole location detecting technology field, be specially a kind of M1C-2 main bearing rivet hole position rule.
Background technology
Main bearing refers to the bearing of engine inner support bent axle, is also important composition parts of steam turbine simultaneously, is called transverse bearing again.Its effect is the total weight bearing rotor and the centrifugal force caused because rotor quality is uneven, determines rotor correct radial position in the cylinder.Because each bearing will bear higher load, and axle journal rotating speed is very high, so the bearing of steam turbine all adopts fluid friction to be the bearing shell formula sliding bearing of theoretical foundation, between axle journal and bearing shell, oil film is formed by means of there being the lubricating oil of certain pressure, set up fluid friction, Turbine Safety is stably run.It can thus be appreciated that the effect of main bearing in steam turbine is vital, the one-piece machine member quality of main bearing directly determines the serviceable life of steam turbine.
And for the bearing of high precision and quality, the accuracy requirement of its rivet hole position is very high, and some traditional measurement and positioning instruments cannot meet the high-acruracy survey demand of main bearing rivet hole far away, need that our solve.
Summary of the invention
A kind of M1C-2 main bearing rivet hole position is the object of the present invention is to provide to advise, to solve the problem that the traditional measurement orientation tool proposed in above-mentioned background technology cannot meet the high-acruracy survey demand of main bearing rivet hole.
For achieving the above object, the invention provides following technical scheme: a kind of M1C-2 main bearing rivet hole position rule, comprise main body, the center position of described main body is provided with the second fixed hole position, the left side of described second fixed hole position is provided with the first fixed hole position, and the right side of the second fixed hole position is provided with the 3rd fixed hole position, the inside correspondence of described first fixed hole position is provided with prismatic pin, the inside correspondence of described second fixed hole position is provided with reference axis, the inside correspondence of described 3rd fixed hole position is provided with rivet pin, the upper surface of described main body is provided with positioning through hole.
Preferably, described positioning through hole is provided with two, and two positioning through hole are separately positioned on the left and right sides of reference axis.
Preferably, four edges of described body upper surface and four edges of lower surface are provided with chamfering, and the physical dimension of eight chamferings is identical.
Preferably, the internal diameter size of described second fixed hole position is the twice of the first fixed hole position and the 3rd fixed hole position internal diameter size.
Preferably, the upper surface of described main body is provided with district of carving characters.
Compared with prior art, the invention has the beneficial effects as follows: this M1C-2 main bearing rivet hole position rule are scientific and reasonable for structure, safe and convenient to use, entirety changes the use-pattern of traditional measurement orientation tool, adopt the three-point fix accurately that cooperatively interacted of reference axis and two positioning through hole, judge whether the position of rivet hole in main bearing meets the requirements by the position relationship of prismatic pin and rivet pin, measuring accuracy is higher, a stable guarantee is had to its processing and use procedure, use and carry convenient, being beneficial to and promoting the use of on a large scale.
