Bolt placement mechanism and installation method of fastening bolt pre-coating lubricant device

Abstract

The invention discloses a bolt arrangement mechanism of a device for pre-coating a fastening bolt with a lubricant and a mounting method of the bolt arrangement mechanism. The bolt arrangement mechanism comprises sliding rails, sliding blocks on the sliding rails, a first bolt arrangement support fixed on the sliding blocks, a second bolt arrangement support fixed at one ends of the sliding rails, bolt arrangement brackets, a bolt rotation driving motors with output shafts and pulleys. The mounting method comprises the steps of mounting the sliding rails and the sliding blocks; mounting one bolt arrangement support; mounting the other bolt arrangement bracket; mounting the bolt rotation driving motors; mounting the pulleys; mounting a proximity switch. The device for pre-coating the fastening bolt with the lubricant, which comprises the bolt arrangement mechanism, can conveniently and easily coat a thread of the fastening bolt with the lubricant, so that the labor intensity of an operator is alleviated, the working efficiency is improved, the phenomena of non-uniform lubricant coating and waste are avoided, and the best coating effect is achieved.

Description

technical field [0001] The invention relates to the field of assembly of wind power generating sets, in particular to a bolt placement mechanism and an installation method of a fastening bolt pre-coating lubricant device. Background technique [0002] In recent years, my country's wind power industry has developed rapidly, and the quality and safety of wind turbines have received more and more attention. In the assembly of wind turbines, bolts are one of the main connection methods for wind turbines. Many key components such as hubs, gearboxes, blades, and towers Almost all mechanical parts are connected by high-strength bolts. The quality of bolts, assembly methods, operators and other factors will affect the final connection quality of threads. In order to reduce the friction coefficient and improve the reliability and safety of the connection, Before assembling high-strength bolts, pretreatment of the threads of the bolts is mainly carried out by manual application of lubri...

Problems solved by technology

[0002]In recent years, China's wind power industry has developed rapidly, and the quality and safety of wind turbines have received more and more attention. In the assembly of wind turbines, bolts are used as the main connection method of wind turbines One, almost all the mechanical parts of hubs, gearboxes, blades, towers and many other key parts are connected by high-strength bolts. The quality of bolts, assembly methods, operators and other factors will affect the final connection quality of threads. In order to reduce the coefficient of friction and improve the reliability and safety of the connection, before assembling the high-strength bolts, pretreatment is carried out on the threads of the bolts. The production is mainly carried out by manually applying lubricants, because a large number of different Standard bolts, holding an ordinary paint brush to apply lubricant to the thread, there are problems such as low production efficiency of manual work, uneven application of lubricant, and waste of lubricant

There has been an automatic bolt coating machine (patent number: 201010108825), but it can only apply glue to small-sized bolts, and the degree of automation is not high. Therefore, it is necessary to design a related bolt coating for the above problems Lubricant device, bolt placement mechanism is an indispensable part of it

[0003]Analysis of the process of manually applying lubricant to fastening bolts, it will take more time to prepare for the pretreatment of bolts in the early stage, and this process will It is an important basis for the final connection quality of the thread. Each bolt requires the operator to hold a brush to apply lubricant to the thread, especially for large-sized bolts. This seems to be a simple job, but it is not an easy job. After the operator continues to work for a period of time, the symptoms of finger stiffness and wrist soreness will appear. Using manual work will also cause problems such as low production efficiency, uneven lubricant coating, and waste.
