Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
As shown in fig. 1-4, the application discloses a bearing bush installation tool, which comprises a driving rod 1, a positioning seat 2 and a protective sleeve 3, wherein one end of the driving rod 1 is a power input end, the other end is a power output end, the positioning seat 2 is arranged at the power output end, the protective sleeve 3 is sleeved on the positioning seat 2 and can axially slide relative to the positioning seat 2, a notch 201 is formed in the outer edge of the positioning seat 2, the protective sleeve 3 and the notch 201 form a placing groove matched with a bearing bush, and the depth of the placing groove is equal to or smaller than the length of the bearing bush.
When the axle tile is installed, firstly, place the axle tile in the standing groove, aim at the axle tile mounting hole with the axle tile to make protective sheath 3 and axle tile mounting hole butt, apply external force to the power input, so that actuating lever 1 drive positioning seat 2 moves towards axle tile mounting hole direction, and because protective sheath 3 and axle tile mounting hole edge butt, so in the motion process, protective sheath 3 its fixed in position, and positioning seat 2 and the axle tile of cover on positioning seat 2 will press into in the axle tile mounting hole, in the in-process of axle tile pressing into the axle tile mounting hole, protective sheath 3 will wrap up the axle tile, in order to provide spacingly for the axle tile, avoid the in-process of axle tile pressing into the axle tile mounting hole to take place to warp, after the axle tile is packed into the axle tile mounting hole completely, can take out positioning seat 2, in order to accomplish the axle tile installation.
The notch 201 is arranged on the positioning seat 2 to be matched with the protective sleeve 3 to form a placing groove for placing the bearing bush, so that the bearing bush is placed conveniently; the protective sleeve 3 can provide limit for the bearing bush in the process of pressing the bearing bush into the bearing bush mounting hole, and further avoid deformation of the bearing bush in the process of pressing the bearing bush into the bearing bush mounting hole.
Meanwhile, in order to prevent the protective sleeve 3 from shifting in the process of pressing the bearing bush into the bearing bush mounting hole, the side surface of the positioning seat 2 is provided with the guide block 202, the protective sleeve 3 is provided with the sliding groove 301 matched with the guide block 202, and the sliding groove 301 extends along the axial direction of the protective sleeve 3 so as to guide the protective sleeve 3, so that the protective sleeve 3 can only move along the axial direction of the positioning seat 2 and cannot shift.
In addition, in order to facilitate the user to align the positioning seat 2 with the bearing bush mounting hole, the application further comprises a guide seat 4, wherein a mounting seat 401 matched with the bearing bush mounting hole is formed on the guide seat 4, a guide rod 402 is arranged at the center of the mounting seat 401, and a guide hole 203 matched with the guide rod 402 is formed at the center of the positioning seat 2.
