Description

Multi-cylinder cone crusher main shaft positioning tool

Technical Field

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

Background

The multi-cylinder hydraulic cone crusher is widely applied to the metal mine metallurgy industry, the building industry, the cement industry, the sand and stone industry and the like, and plays an important role in nuclear power, expressways, airports, mines and other projects. In recent years, due to market changes and demands, both users and manufacturers of multi-cylinder hydraulic cone crushers have great interest in domestic multi-cylinder hydraulic cone crushers. The multi-cylinder hydraulic cone crusher has become a machine type which is focused in the current crusher industry.

The multi-cylinder hydraulic cone crusher is firstly used in large scale in China, and is in the artificial stone project of the three gorges in 1996, and therefore, the multi-cylinder hydraulic cone crusher is gradually applied to the domestic large-scale mine industry and the sand and stone aggregate industry. In 2001, the first multi-cylinder hydraulic cone crusher in China shipped from Shenyang. In recent years, with the demand for rapid development of domestic economy and the improvement of machining level, manufacturers for producing multi-cylinder hydraulic cone crushers are gradually increased in China.

The multi-cylinder hydraulic cone crusher is a typical crushing device for medium crushing and fine crushing of hard materials, adopts a 'lamination crushing' principle, improves the yield of primary crushing, and is simpler and more convenient to maintain and lower in operation cost. The structure strength is improved by adopting measures of separating the movable cone from the main shaft, thickening the main shaft and fixing the main shaft, only making the movable cone perform rotary swing motion and the like.

The main shaft of the multi-cylinder hydraulic cone crusher is assembled and fixed on the frame, so that the main shaft and the frame are required to be matched with each other in a large interference range, and the stability of the main shaft during production and operation of the crusher can be ensured. Due to the large interference, the assembly of the main shaft and the frame of the multi-cylinder hydraulic cone crusher usually adopts a press-fitting process, namely the main shaft is pressed into a frame hole by an oil press. Or a cold-loading process is adopted, namely the main shaft is put into a liquid nitrogen refrigerator for freezing, and the main shaft is assembled in the hole of the frame after being cooled to a set temperature. And a cold and hot assembly process is also adopted, namely the spindle is frozen by using dry ice, but the dry ice is not enough to cool the spindle to an assembly size, so that the position of the mounting hole of the rack is heated, and the frozen spindle is assembled into the mounting hole of the rack after the spindle is heated to the required temperature.

The final purpose of the method is to install the main shaft into the frame and ensure that the interference magnitude between the main shaft and the frame meets the design requirements no matter what method is adopted. And the interference magnitude of the main shaft and the frame is ensured by the downward displacement of the main shaft during assembly. When the hydraulic press is assembled, the displacement of the main shaft is measured by adopting a dial indicator, and when cold assembly or cold and hot assembly is adopted, the displacement of the main shaft is manually measured and calculated.

The method mainly adopts assembly methods such as cold charge, hot charge, pressure equipment, etc. to apply the main shaft of the multi-cylinder cone crusher at present, but these methods have the following disadvantages, 1. the displacement of the main shaft needs to be measured during assembly, the assembly failure of the main shaft can be caused no matter the failure of a measuring instrument or the error of a measuring person, and the assembly failure of the main shaft can come to a great deal of rework work; 2. the safety is poor, and survey personnel need measure high temperature or ultra-low temperature part, or measure under the hydraulic press, even have special protector, have the potential safety hazard at all.
