Embodiment Construction

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 3 Shown seal holder based on laser arm measurement technology for clamping ring seals.

[0034] The fixing tool includes a bottom plate, a chassis 1 , a slider, a bolt 3 and a positioning block 4 .

[0035] The base plate and the base plate 1 are integrally processed and formed, wherein the base plate 1 is a circular boss, and the base plate can be a circular flat plate or a rectangular flat plate. The chassis 1 is located above the bottom plate.

[0036] During measurement, the base of the laser arm is fixed on the base plate by magnetic attraction to avoid relative displacement between the laser arm and the chassis 1 .

[0037] On the chassis 1, a groove is machined at intervals of 120° with the center of the circle as the center. The groove is a T-shaped groove or a dovetail groove. There are tick marks...

Abstract

The invention relates to the technical field of laser measurement, in particular to a sealing element fixing tool based on a laser arm measurement technology, which is used for clamping an annular sealing element and comprises a bottom plate, a chassis, a sliding block, a bolt and a positioning block, the bottom plate and the base plate are integrally machined and formed, and the base plate is a circular boss; the chassis is positioned above the bottom plate; during measurement, the base of the laser arm is fixed on the bottom plate through magnetic attraction, so that relative displacement between the laser arm and the chassis is avoided; n grooves are formed in the base plate at equal-angle intervals with the circle center as the center, and N is larger than or equal to 3. And the edge of each groove is provided with scale marks. According to the fixing tool, the sliding block telescopically moves in the groove, so that the fixing tool is suitable for fixed measurement of sealing elements of different specifications.

Description

technical field [0001] The invention belongs to the technical field of laser measurement, in particular to a sealing member fixing tool based on the laser arm measurement technology. Background technique [0002] The annular seals that need to be installed in some system pipelines and equipment of nuclear power plants, such as standard or non-standard metal graphite gaskets, metal O-rings, etc., require high processing and installation dimensional accuracy. However, during the fixing process of the relevant annular seals, the encoder on the joint arm of the three-coordinate laser measuring instrument often transmits wrong signals due to force deformation or poor positioning, so that the measured size and tolerance data and the actual value exist certain deviation. [0003] Therefore, there is an urgent need to design a fixing device to solve the above problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a sealing member fixing to...
