Description

A multi-cylinder cone crusher spindle positioning tool

technical field

The utility model belongs to the field of ore equipment, in particular to a main shaft positioning tool of a multi-cylinder cone crusher.

Background technique

Multi-cylinder hydraulic cone crushers are widely used in metal mining, metallurgy industry, construction industry, cement industry, sand and gravel industry, etc., and play a very important role in nuclear power, highway, airport and mining projects. In recent years, due to market changes and demands, both domestic crusher users and manufacturers have developed a strong interest in multi-cylinder hydraulic cone crushers. The multi-cylinder hydraulic cone crusher has become the focus of the current crusher industry.

The first large-scale use of multi-cylinder hydraulic cone crushers in my country was in the Three Gorges artificial stone project in 1996. Since then, multi-cylinder hydraulic cone crushers have been gradually applied in large-scale domestic mining industries and sand and gravel aggregate industries. In 2001, China's first multi-cylinder hydraulic cone crusher left the factory in Shenyang. In recent years, with the needs of the rapid development of the domestic economy and the improvement of the level of machining, the number of domestic manufacturers of multi-cylinder hydraulic cone crushers has gradually increased.

Multi-cylinder hydraulic cone crusher is a typical crushing equipment for medium and fine crushing of hard materials. It adopts the principle of "lamination crushing" to improve the yield of primary crushing, easier and convenient maintenance and lower operating costs. The moving cone is separated from the main shaft, the main shaft is thickened and fixed, and only the moving cone does the swinging motion and other measures to improve the structural strength.

The main shaft of the multi-cylinder hydraulic cone crusher is assembled and fixed on the frame, which requires a large interference fit between the main shaft and the frame to ensure the stability of the main shaft during the production and operation of the crusher. Due to the large amount of interference, the assembly of the main shaft and the frame of the multi-cylinder hydraulic cone crusher usually adopts the press-fitting process, that is, the main shaft is pressed into the frame hole with a hydraulic press. Or the cold-packing process is adopted, that is, the main shaft is put into a liquid nitrogen refrigerator for freezing, and when the main shaft is cooled to the set temperature, it is assembled into the rack hole. There are also hot and cold assembly processes, that is, the main shaft is frozen with dry ice, but the dry ice is not enough to cool the main shaft to the size that can be assembled. This requires heating the position of the mounting hole of the rack, heating to the required temperature, and then freezing it. The spindle fits into the frame hole.

No matter which method is adopted, the ultimate goal is to install the main shaft into the frame and ensure that the interference between the main shaft and the frame meets the design requirements. The amount of interference between the main shaft and the frame is ensured by the downward displacement of the main shaft during assembly. When the hydraulic press is used for assembly, the dial indicator is used to measure the displacement of the main shaft. When cold assembly or hot and cold assembly is used, the displacement of the main shaft is manually measured and calculated.

At present, the main shaft of the multi-cylinder cone crusher on the application site mainly adopts cold fitting, hot fitting, press fitting and other assembly methods, but these methods have the following disadvantages: 1. The displacement of the main shaft needs to be measured during assembly, whether it is the failure of the measuring instrument or the measurement Personnel mistakes will cause spindle assembly failure, and spindle assembly failure will result in a lot of rework; 2. Poor safety, measurement personnel need to measure high-temperature or ultra-low temperature parts, or measure under a hydraulic press, even with special protective devices, still There are security risks.
