A four-degree-of-freedom vertical installation platform

Abstract

The invention discloses a four-freedom-degree vertical type installing platform. A supporting platform, a winch driving system, a lifting appliance supporting plate, a lifting appliance, a position and posture adjusting mechanism, a guide rail installing plate, guide rails and a slider are included. The supporting platform comprises tapered iron, an escalator, a guide rail fixing frame and an operating platform; the winch driving system comprises winches, a guiding pulley, a traction rope and a hoisting ring; the two winches are arranged, and are correspondingly arranged on first-stage and second-stage platform bodies of the supporting platform; the position and posture adjusting mechanism comprises a hoisting lug, a position adjusting support and two symmetrically arranged X and Y movement adjusting tables; the X and Y movement adjusting tables each mainly comprise a bottom plate, four guide rails, four sliders, a workbench, connection rods and four driving devices; each driving device comprises a servo motor, a coupler, a band-type brake, a speed reducer and a ball screw; a connection mechanism comprises a hand wheel, a connection rod force bearing frame, a connecting rod, a telescopic spring and a pressing plate; and the two guide rails are arranged and are symmetrically installed on a guide rail installing plate, and mechanical limiting stopping blocks are installed at thetail ends.

Description

technical field [0001] The invention relates to large component assembly technology, in particular to a four-degree-of-freedom vertical installation platform for large assembly. Background technique [0002] In the manufacturing process of aerospace satellites, the assembly of the satellite cabin and the satellite body is a time-consuming and labor-intensive link. Since the satellite cabin and the satellite body weigh more than one ton, and the size and outline are relatively large, mostly several meters high, there are a lot of high-precision components attached to it. Assembling electronic components together can easily cause bumps or damage to components due to improper operation, causing serious losses to production. At present, the assembly of the two is completed by a lot of manpower, and it takes a long time, and the production efficiency is extremely low, which is contrary to the development direction of the modern technology of high precision and automatic assembly....

[0002] In the manufacturing process of aerospace satellites, the assembly of the satellite cabin and the satellite body is a time-consuming and labor-intensive link. Since the satellite cabin and the satellite body weigh more than one ton, and the size and outline are relatively large, mostly several meters high, there are a lot of high-precision components attached to it. Electronic components, assembling them together is easy to bump or damage parts due to improper operation, causing serious losses to production

At present, the assembly of the two is completed by a lot of manpower, and it takes a long time, and the production efficiency is extremely low, which is contrary to the development direction of modern technology of high precision and automatic assembly.

Moreover, the current assembly technology for large parts is mostly horizontal assembly, and the influence of their own gravity on each other during assembly is often not negligible, and the requirements for the process are more stringent.
