Coating transmission mechanism of fastening bolt lubricant pre-coating device and mounting method of coating transmission mechanism

Abstract

The invention discloses a coating transmission mechanism of a fastening bolt lubricant pre-coating device and a mounting method of the coating transmission mechanism. The coating transmission mechanism comprises a main frame, a main brush roll drive motor, an auxiliary brush roll drive motor, a lubricant storage box, a main brush roll assembly and an auxiliary brush roll assembly. The mounting method comprises the following steps: mounting the main frame; mounting the brush roll drive motors; mounting the main brush roll assembly; mounting the auxiliary brush roll assembly; mounting the lubricant storage box. According to the coating transmission mechanism, an original mode of coating a thread of a bolt by manually holding a paint brush by a hand is replaced with a mode of coating the thread of the bolt by driving a roller brush by an electromechanical transmission device; the thread of the fastening bolt can be conveniently and easily coated with a lubricant, the labor intensity of operators is alleviated, the working efficiency is improved, the non-uniform coating and the waste of the lubricant are prevented, and a 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 coating transmission mechanism of a fastening bolt pre-coating lubricant device and an installation method thereof. 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 applic...

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, and the coating transmission mechanism of the bolt coating lubricant device is its key component

[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.
