Description

Cone crusher base spindle hole pressure testing device

Technical field

The utility model is related to mining equiment manufacturing technology fields more particularly to a kind of cone crusher base spindle hole to try Pressure device.

Background technology

Gyratory crusher be it is a kind of suitable for it is metallurgical, build, build the road, chemistry and silicate industry raw material crusher Tool.Because its reduction ratio is big, efficient, low energy consumption, product granularity is uniform, broken and fine crushing various ores in being suitble to, rock.Fortune extensively For numerous departments such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.

Cone crusher base is casting, and engine base is hollow structure, is internally provided with the spindle hole component of tubular structure. It is easy in casting the defects of spindle hole hole wall generates blow hole, sand holes.And spindle hole when gyratory crusher normal work Enough high pressure oils can be passed through in gap between main shaft, if high pressure when spindle hole can cause to work normally there are drawbacks described above Oil can be leaked from penetrability casting flaw, and oil pressure is caused to decline, and anti-wear effect is deteriorated, and wear bearing shell or main shaft, and cause to lubricate Oil stream is become estranged environmental pollution.

These exactly above-mentioned defects need individually to carry out pressure testing to spindle hole there may be so that engine base before assembling, due to Main shaft pore size is larger, and when pressure testing often needs to carry out pressure testing again after being sealed spindle hole both ends.The prior art is generally taken Spindle hole upper and lower end face fills gasket, then tightly carries out end face static seal pressure testing with bolt handle by big steel plate.But practical examination When pressure, since bolt hole is not arranged in wherein one end of engine base so that steel plate is often inconvenient fixed, and individually increases bolt hole meeting Influence the product quality of entire product.Simultaneously because main shaft pore size is larger so that pressure testing steel plate board size is also larger so that Steel plate is easily deformed when pressure testing, or even rupture.Bolt of the end of spindle hole for fastening under high pressure can be elongated so that end Surface pressure reduces, and causes poorly sealed easy leakage.And fabrication hole is also reserved on the lateral wall of part spindle hole upper end, and this work Skill hole inner wall and outside are all blank, and sealing is difficult, and the prior art is sealed using welding steel plate, but can be caused in actual use Main shaft bore deformation influences entire product quality.
