升降舞臺如何做好平行度控制設計？

升降舞臺隨滑塊在滑道中移動而升降，設計要求滑塊移動距離相同時，兩組平臺升降距離相同，因此在設計時要做好平行度控制。

1、由于設計要求升降舞臺http://m.8kvv.com/90個單元閉合高度為恒定值，因而設計工裝共4件，放在大平臺的四個角，大平臺放在工裝上后就能夠保證大平臺在同一高度。很多情況下，上軸承座和大平臺有間隙，此時調(diào)整油缸活塞桿，使某一軸承座和大平臺之間無間隙，如有間隙時墊入合適厚度鋼板，軸承座和大平臺焊接牢固。
Due to the design requirements for the lifting stage 90 units closed height is a constant value, thus a total of four tooling design, on the four corners, a large platform on a large platform after tooling to ensure a large platform at the same height. In many cases, the bearing and a large platform with a gap, then adjust the cylinder piston rod, so that no gap between the bearing and a large platform, pad into the appropriate thickness steel plate if clearances,bearing housings and a large platform welding firm.

2、上滑道安裝是確保升降舞臺在升降過程中滿足大平臺平行度的關鍵，根據(jù)機構設計原理，上、下軸承座和下滑道固定的情況下，如果上、下滑道不平行，厚鋼板點處上滑道和大平臺有間隙。
The slide installation is key to ensuring a large platform parallelism landing stage to meet the lifting process, according to mechanism design theory, on the case of a fixed bearing and glideslope, if on the glide path is not parallel,the thick steel plate at the point slides and a large platform with a gap.

3、升降舞臺http://m.8kvv.com/用行車吊在大平臺重心點，平穩(wěn)升至最大凈升高度，測量大平臺4個角的高度，確保4個角升高距離在允差范圍內(nèi)，此時上滑道和大平臺間隙墊入合適厚度鋼板，上滑道和大平臺焊接牢固。
Landing stage hung a large platform with a driving focus point, steady rise to a maximum net lifting height, height measuring large platform four corners, four corners to ensure increased distance is within the tolerance range, this

time on a slide and a large gap between the pad into a suitable platform the thickness of the steel, the slide and a large platform welding firm.
