Abstract

The invention discloses a press-mounting mechanism and device. According to the press-mounting mechanism and device, the technical problem that a press-mounting device provided by the correlative technology is liable to be damaged so as to have the short service life is solved. The press-mounting mechanism comprises a propelling assembly. The propelling assembly comprises at least two pushing blocks arranged in sequence in the same circumferential direction. An inserting hole used for inserting of the small-diameter end of a taper sleeve is defined by the at least two pushing blocks. Additionally, the at least two pushing blocks can get close to each other synchronously or be away from each other synchronously in the radial direction of the circumference to enable the diameter of the inserting hole to be adaptive to the outer diameter of the taper sleeve.

Description

technical field [0001] The invention relates to the field of press-fit technology, in particular to a press-fit mechanism and a press-fit device. Background technique [0002] The piston ring is a seal of hydraulic equipment, such as a hydraulic cylinder, and the piston ring is set between the cylinder and the piston rod for sealing. The installation quality of piston rings is directly related to the qualification rate of hydraulic equipment, and the installation efficiency of piston rings can directly affect the production efficiency and maintenance cycle of hydraulic equipment. [0003] The related art provides a pressing device, such as figure 1 As shown, the press-fitting device includes a transition taper sleeve 1, an elastic propeller 2 and a fixed mandrel 3, wherein the large-diameter end of the transition taper sleeve 1 is used to insert the piston 5, and the fixed mandrel 3 is inserted into the transition taper sleeve 1; the elastic propeller 2 is sleeved on the o...
