Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1 to 4, the bearing bush mounting tool disclosed by the application 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 of the driving rod is a power output end, the positioning seat 2 is mounted 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 less than the length of the bearing bush.
When installing the axle bush, place the axle bush in the standing groove earlier, aim at the axle bush mounting hole with the axle bush, and make protective sheath 3 and axle bush mounting hole butt, exert external force to the power input end, so that 1 drive positioning seat 2 of actuating lever moves towards axle bush mounting hole direction, and because protective sheath 3 and axle bush mounting hole edge butt, so in the motion process, its rigidity of protective sheath 3, and positioning seat 2 and cover establish the axle bush mounting hole that will impress on positioning seat 2, at the in-process of axle bush mounting hole that impresses, protective sheath 3 will wrap up the axle bush, in order can provide spacingly for the axle bush, avoid the in-process emergence deformation of the axle bush mounting hole that the axle bush is impressed, after the axle bush mounting hole is packed into completely, can take out positioning seat 2, in order to accomplish the axle bush installation.
The positioning seat 2 is provided with the notch 201 to be matched with the protective sleeve 3 to form a placing groove for placing the bearing bush, so that the bearing bush can be conveniently placed; the protective sheath 3 that sets up can provide spacingly for the axle bush at the in-process that the axle bush mounting hole was impressed to the axle bush, and then avoids the axle bush to take place to warp at the in-process of impressing the axle bush mounting hole.
Simultaneously, for avoiding the axle bush in the in-process of axle bush mounting hole of impressing, the skew takes place for protective sheath 3, and this application still is provided with guide block 202 in the 2 sides of positioning seat, set up on protective sheath 3 with the spout 301 of guide block 202 adaptation, and spout 301 extends along the axial direction of protective sheath 3 to can lead for protective sheath 3, make protective sheath 3 only can follow the axial direction of positioning seat 2 and move, can not take place the skew.
In addition, for the person of facilitating the use with positioning seat 2 aim at the axle bush mounting hole, this application still includes guide holder 4, is formed with the mount pad 401 with the axle bush mounting hole adaptation on the guide holder 4, and the center of mount pad 401 is provided with guide bar 402, and the guiding hole 203 with the guide bar 402 adaptation is seted up at the center of positioning seat 2.
In use, the mounting seat 401 is first installed in the bushing mounting hole, and then the guiding hole 203 is matched with the guiding rod 402, and the positioning seat 2 is aligned with the bushing mounting hole, so that the user can apply power towards the driving end to move the positioning seat 2 towards the bushing mounting hole, so as to press the bushing into the bushing mounting hole.
Because the guide hole 203 is sleeved with the guide rod 402, in the process that the positioning seat 2 moves towards the bearing bush mounting hole, the guide rod 402 synchronously moves towards the bottom of the guide hole 203, thereby squeezing the air in the guide hole 203, and when the air in the guide hole 203 is compressed to a certain degree, the movement of the guide rod 402 is affected, the guide rod 402 cannot move towards the bottom of the guide hole 203, so that the positioning seat 2 cannot move towards the bearing bush mounting hole, so as to press the bearing bush into the bearing bush mounting hole, therefore, the bottom of the guide hole 203 is provided with a first air release hole, the side surface of the driving rod 1 is provided with a second air release hole 2032 communicated with the first air release hole 2031, in the process that the guide rod 402 moves towards the bottom of the guide hole 203 synchronously, the air in the guide hole 203 continuously leaks into the outside air from the first air leakage hole 2031 and the second air leakage hole 2032 without limiting the movement of the guide rod 402.
And in order to make things convenient for guide bar 402 to pack into guiding hole 203, this application is provided with the chamfer at guiding hole 203 and guide bar 402 edge, and when guide bar 402 and guiding hole 203 cooperate, guide bar 402 can be drawn into in the guiding hole 203 along the chamfer.
In addition, because the axle bush comprises two axle bush pieces, so there is the gap of two symmetries on the axle bush, and because of the installation demand, the straight line that two gaps of axle bush link must keep perpendicular with the direction of gravity, so this application has seted up constant head tank 302 in the side of protective sheath 3, constant head tank 302 middle part is provided with locating piece 303, locating piece 303 is suitable for and aligns with the axle bush seam, with the direction of confirming the axle bush on positioning seat 2, then align constant head tank 302 and the preset positioning line in axle bush mounting hole edge, thereby make the axle bush in-process of impressing the axle bush mounting hole, the straight line that two gaps of axle bush link must keep perpendicular with the direction of gravity, in order to satisfy the installation demand.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
