The outlet of the hydraulic oil pump 1 communicates with the inlet of the reversing valve 10 , t...

Embodiment 2

[0036] Embodiment 2: as Figure 5 and Image 6 As shown, on the basis of the foregoing embodiment 1, the hydraulic cylinder 6 is rotatably connected to the top of the door-shaped frame 5 through a rotating shaft, and one end of the rotating shaft is connected with a positioning locking mechanism. The positioning locking mechanism includes an indexing plate 16 that is rotationally connected with the rotating shaft and fixed on the door-shaped frame 5; a rotating handle 17 that is rigidly connected at one end with the rotating shaft; the indexing plate 16 has a plurality of Positioning hole, the rotating handle 17 has a waist-shaped hole, and the positioning pin 18 passing through the waist-shaped hole is inserted into the positioning hole to fix the position of the rotating shaft.

Embodiment 3

[0037] Embodiment 3: as Figure 7 and Figure 8 As shown, on the basis of the foregoing embodiment 1, the hydraulic cylinder 6 is rotatably connected to the top of the door-shaped frame 5 through a rotating shaft, and one end of the rotating shaft is connected with a positioning locking mechanism. One end of the rotating shaft is provided with a threaded rod 20 ; the positioning locking mechanism includes a first fastening nut 21 and a second fastening nut 19 which are threadedly connected with the threaded rod 20 . After adjusting the position of the hydraulic oil cylinder 6 , by rotating the first fastening nut 21 , a frictional force is generated between the first fastening nut 21 and the door frame 5 , thereby fixing the position of the hydraulic oil cylinder 6 . The second fastening nut 19 prevents the first fastening nut 21 from loosening.

Abstract

The invention provides a bearing installation device and a bearing installation method. The bearing installation device comprises a bottom board (13), a gate-shaped frame (5), a hydraulic oil cylinder (6), a hydraulic system (4), a reversing valve (10) and an overflowing valve (9), wherein the gate-shaped frame (5) is connected with the bottom board (13), the hydraulic oil cylinder (6) is connected with the gate-shaped frame (5), a piston rod of the hydraulic oil cylinder (6) faces downwards, the hydraulic system (4) is provided with a hydraulic oil pump (1), the reversing valve (10) is connected with the hydraulic oil pump (1) through a pipeline, and the overflowing valve (9) and the hydraulic oil cylinder (6) are connected with the reversing valve (10) through pipelines. The bearing installation method comprises the following steps that a bearing pedestal (8) is placed below the hydraulic oil cylinder (6); the first end of a bearing (7) is pressed in a hole of the bearing pedestal (8); a pressing plate (14) is placed at the second end of the bearing (7); the piston rod of the hydraulic oil cylinder (6) moves downward, and therefore the bearing (7) is pressed in the hole of the bearing pedestal (8); the piston rod of the hydraulic oil cylinder (6) moves upward, and the pressing plate (14) covering the end face of the bearing and the bearing pedestal (8) provided with the bearing are taken off.

Description

technical field [0001] The invention relates to a bearing installation device, in particular to a device capable of quickly installing a bearing into a bearing housing; the invention also relates to a bearing installation method. Background technique [0002] When the outer ring of the bearing fits tightly with the housing hole, and the inner ring fits loosely with the shaft, generally the bearing is pressed into the housing hole first. Whether the bearing is installed well or not will affect the accuracy, life and performance of the bearing. During the installation of the bearing, it should be carried out in a clean and dust-free space as much as possible. There are three methods of bearing installation: cold assembly method, hot assembly method and hydraulic assembly method. When using the existing technology to install the bearing, the bearing is symmetrically impacted during the installation process, and the force point is not easy to grasp during the impact process.
