Device and method for precoating fastening bolt with lubricant

Abstract

The invention discloses a device and a method for precoating a fastening bolt with a lubricant. The device comprises a working table, a coating transmission mechanism fixed on the working table, a bolt arrangement mechanism arranged in the front of the coating transmission mechanism, and a control box arranged on the lateral side of the coating transmission mechanism, wherein the bolt arrangement mechanism and the control box are further fixedly arranged on the working table; the coating transmission mechanism comprises a main rack, a main brush roll driving motor, a secondary brush roll driving motor, a lubricant storage box, a main brush roll assembly and a secondary brush roll assembly. The method comprises the following steps: supplying a working power source; setting the rotation directions of a main brush roll and a secondary brush roll; arranging coated bolts; starting to coat; and completing coating. The device and the method provided by the invention can be used for conveniently and easily coating a thread of the fastening bolt with a lubricant, so that the labor intensity of an operator is alleviated, the working efficiency is improved, and the lubricant is prevented from being coated in a non-uniform manner, the waste can be avoided; meanwhile, the optimal coating effect can be achieved.

Description

technical field [0001] The invention relates to the field of assembly of wind power generating sets, in particular to a device and method for pre-coating lubricant on fastening bolts. Background technique [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 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 lubricants. Because a large number of bolts of...

[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

[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.
