Problems solved by technology

These operations need to be carried out manually, especially before the piston rod of the mobile press machine passes through the copper bushing of the boom or the composite bushing, the mobile press machine must first be manually positioned at a predetermined height, not only installation, disassembly, fixing The method is cumbersome and inconvenient to operate, resulting in less frequent use in practice
[0003] Therefore, there is the problem of cumbersome pressing operations in the prior art

Abstract

The invention discloses a press mounting oil cylinder and press mounting equipment. An insert groove (13) used for detachably mounting a press plate (40) is arranged at an extending end of a piston rod (12) of the pres mounting oil cylinder (10). Via the insert groove, the press plate used for press mounting can be conveniently mounted and dismounted. Specifically, during use, subsequent press mounting operation can be conveniently performed by only inserting the press plate into the insert groove, and when not used, the press plate can be conveniently taken down from the insert grooved, and thereby, the process for press mounting is simplified.

Description

technical field [0001] The invention relates to workpiece assembly, in particular to a press-fit oil cylinder and press-fit equipment comprising the press-fit oil cylinder. Background technique [0002] Press-fitting heavy workpieces (such as copper sleeves and composite bushings for medium-tonnage booms) has always been a difficult point in the industry. For example, for the installation of medium tonnage boom copper bushings and composite bushings, two methods are usually used: one is that workers use steel rods or copper rods to directly knock, and the other is to use mobile hydraulic presses for assembly. Direct knocking with steel rods will generate a lot of noise, not only labor-intensive, but also damage the surface of the copper sleeve. The use of the mobile press greatly reduces the labor intensity, but because the end of the piston rod of the mobile press needs to be passed through the boom copper sleeve or composite bushing first, and then the end of the mobile p...
