The all-important task of the lift equipment is that it is to stipule the jointed work pieces after they have been jointed. It makes the work pieces leave the jig and convenient to move away from jigs. It works to work in the jigs of product line. It is used to underlay the orbits, work pieces on orbits and other equipment of every work position. It requests the equipment to completes the action of lifting and descending. This lift equipment is composed of air pressure system, gear and rack drive system, lift shelf, orbits, BASE board and other parts.
In this design, the lift equipment need to lift about 762.2kg’s weight and the range it need to lift is 0~400mm. It has two orbits, which are away from 400mm, which based on the need of the bodywork’s shape and size. Besides, the bodywork can slippage on the orbits to and fro on the pulley. Between the process of design, we should assure that the lift flat roof is balanceable and smooth. For shake of meeting this need, we adopt gear and rack drive system, and the rake is the machinery of oriented axes. In this way, the lift equipment’s action is accordant, and it can assure the placidity and reliability of lifting.
air pressure system is the action energy sources of the whole system. For the shake of assuring the lift of the work body favoring, we need choose the diameter and journey of the air pressure crocks basing the lift weight and the result of calculation.
At the present time, this equipment is being perfected and improved which make the capability more predominant. Doing these is for achieving one-up level in home and advanced level in foreign countries, and occupy domestic market gradually. In the end, it can come into the foreign markets.
Key words: lift equipment, air pressure system, gear and rack drive system
