Embodiment Construction

[0033] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0034] Such as figure 2 Shown; A tube sheet deep hole verticality measuring tool, which includes: bracket 2; handle 3, which is vertically arranged above the bracket 2; mandrel 4, which is vertically arranged below the bracket 2; thimble 5, It is vertically arranged at one end of the support 2, and the bottom of the thimble 5 is provided with a tip 51; the dial indicator 6 is vertically arranged at the other end of the support 2, and the bottom of the dial indicator 6 is provided with a measuring rod 61. The size of the mandrel 4 matches the size of the deep hole 1 to be measured, ensuring that the axis of the mandrel 4 remains coaxial with the axis of the deep hole 1 during testing.

[0035] In this embodiment, the size tolerance range of the deep hole 1 is Φ20.68 (+0.09 / -0.04). Due to the large number of deep...

Abstract

The invention discloses a measurement tool of verticality of a deep hole of a tube plate. The measurement tool comprises a support, a handle vertically arranged above the support, a core rod vertically arranged below the support, a center vertically arranged at one end of the support, and a dial indicator vertically arranged at the other end; and a tip is formed at the bottom of the center and a measurement rod is arranged at the bottom of the dial indicator. The measurement tool has the following advantages: thousands of to-be-measured deep holes can be aligned rapidly and can be measured one by one; adjustment and extra fixation are not required; and the operation is convenient.

Description

technical field [0001] The invention relates to the field of precise detection, in particular to a tool for measuring verticality of deep holes in a tube plate and a measuring method thereof. Background technique [0002] The deep hole drilling of the tube plate of the nuclear power evaporator is a major processing and manufacturing node in the entire evaporator manufacturing. Seriously restrict the manufacturing cycle of the whole evaporator. Including, it will take a lot of energy for the inspection engineer to measure the size and position of each pipe hole after the deep hole is drilled; figure 1 As shown, the deep hole 1' on the tube sheet 7' has a depth of 890mm and a through hole with a size of Φ20.68 (+0.09 / -0.04). Φ20.64~Φ20.77. Contents of the invention [0003] The object of the present invention is to provide a tube sheet deep hole perpendicularity measuring tool and its measuring method, which can align each deep hole to be measured, and quickly measure whe...
