Portable bearing hydraulic assembly and disassembly device

Abstract

The invention provides a portable type hydraulic bearing mounting and dismounting device and relates to a hydraulic mounting and dismounting device. The portable type hydraulic bearing mounting and dismounting device comprises a hydraulic system, a working oil cylinder, a pressing plate and a base plate, wherein the hydraulic system comprises an oil tank; the working oil cylinder comprises an oil cylinder barrel and a piston rod; the piston rod is mounted in the oil cylinder barrel; the oil cylinder barrel and the oil tank are connected together through a soft pipe; the pressing plate is located on one side for mounting an engine base framework of a bearing; one end of the pressing plate is nested and connected and the other end of the pressing plate is in contact with the end part of the oil cylinder barrel of the working oil cylinder; the base plate is located on one side of the engine base framework; and a stretching-out end of the piston rod of the working oil cylinder sequentially penetrates through the pressing plate, the engine base framework and the base plate to be connected with a nut. The portable type hydraulic bearing mounting and dismounting device is applicable to mounting and dismounting of bearings of structure pieces with relatively large volume and mass, has the characteristics of small noises, high bearing mounting precision, low labor intensity, high working efficiency, safe and reliable structure, low cost, and convenient and flexible operation, and is particularly suitable for mounting and dismounting the bearings in the structure pieces with various types in various working positions.

Description

technical field [0001] The invention relates to a bearing assembly and disassembly device, in particular to a portable bearing hydraulic assembly and disassembly device. Background technique [0002] The general assembly plants of large-scale machinery manufacturing enterprises generally have long-term and serious noise exceeding the standard. During working hours, the highest noise level in some enterprise workshops is above, and rarely below . The reason for this serious noise pollution is that the product assembly process is brutally backward. [0003] Because the products assembled by the general assembly plant of large-scale machinery manufacturing enterprises are mostly composed of relatively large steel plate tailor-welded structural parts, their surface area is large and their ability to radiate noise is very strong. When assembling the bearing to the steel plate structure, it has been using the method of artificially swinging a sledgehammer to hit it vigorously...
