Abstract

The invention discloses an outdoor shaft sleeve pulling and pressing device for excavators and belongs to the field of machinery manufacturing. The outdoor shaft sleeve pulling and pressing device comprises a power assembly (3), a support part (4) and a sleeve part (5). A shaft sleeve (1) is arranged in the shaft hole of a shaft (2). The power assembly (3) comprises a power mechanism (6), a cylinder (7) and a piston rod (8). The power mechanism (6) drives the piston rod (8) to extend out or retract into the cylinder (7). The support part (4) is connected with the cylinder (7), and the sleeve part (5) is connected with the other end of the piston rod (8). A first acting plane (9) acting with the shaft (2) is arranged on the support part (4), while a second acting plane (10) acting with the shaft sleeve (1) is arranged on the sleeve part (5). When the piston rod (8) extends out or retracts into the cylinder (7), the direction of force that the first acting plane (9) applies upon the shaft (2) is opposite to that the second acting plane (10) applies upon the shaft sleeve (1). By the arrangement that the shaft sleeve is pressed out by exerting force upon the cylinder and the piston rod in the opposite direction, greater convenience is brought to outdoor operation, with no need for carrying larger power sources, thus the outdoor shaft sleeve pulling and pressing device can save both time and labor, and damage to the shaft hole is less.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a shaft sleeve pulling and pressing device, in particular to a field shaft sleeve pulling and pressing device for an excavator. Background technique [0002] When replacing the bushing in the field, due to the lack of powerful equipment, flame cutting is often used to cut a gap in the bushing to weaken the bonding force between the bushing and the shaft hole, and then knock out the bushing. [0003] But this method is time-consuming and labor-intensive, and the strength of the material will be reduced after the shaft hole is baked by flame, which will affect the bonding force with the shaft sleeve, making it easier for the shaft sleeve to escape. [0004] At the same time, it is inconvenient and unsafe to carry flame cutting equipment. In addition, the bush assembly devices in the prior art can only be used in the factory, and do not provide the function of pullin...
