These terms are only used to distinguish one element from another element. Therefore, a first element may be referred to as a second element without departing from the teachings of the present application.

[0023] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.

[0024] Figure 1 and Figure 2 A portable ball joint disassembly and assembly tool is shown, which is mainly composed of a working cylinder 10 and a press-fitting sleeve 20 arranged inside the working cylinder 10. A pressure member 30 is arranged at the top of the working cylinder 10 to drive the press-fitting sleeve 20 to move and squeeze the ball joint 2, and an adjustment disk 40 is arranged at the bottom of the working cylinder 10 for adjusting the press-fitting angle of the connecting rod 1.

[0025] Specifically, a press-fitting cavity 12 is provided in the working cylinder 10, and the press-fitting sleeve 20 is placed in the upper part of the press-fitting cavity 12 and connected to the press-fitting member 30. The press-fitting sleeve 20 is a hollow structure with a pressure head 21 provided at the bottom. The pressure head 21 is designed to be annular to match the cross-sectional shape of the joint with the ball joint 2 to ensure that it fits tightly when squeezing the ball joint 2. The press-fitting member 30 is composed of a nut 31 fixed to the top of the working cylinder 10 and a bolt 32 screwed into the nut 31. The bolt 32 passes through the working cylinder 10 and engages with the groove 22 at the top of the press-fitting sleeve 20. By rotating the bolt 32, its insertion depth is changed to push the press-fitting sleeve 20 to move. The groove 22 prevents the bolt 32 from being displaced from the press-fitting sleeve 20 during the tightening process. A first through hole 14 is provided at the bottom of the working cylinder 10, and an adjustment disk 40 is hinged in the first through hole 14. The adjusting disk 40 is provided with a positioning plate 42 extending downward and a second through hole 41 for the ball shaft 2a to extend from the working cylinder 10, and the second through hole 42 is coaxial with the first through hole 14. By rotating the adjusting disk 40, the positioning plate 42 is rotated to the press-fitting angle of the ball joint 2, so that the mounting surface 2b of the ball shaft 2a fits with the positioning plate 42, ensuring that the ball joint 2 is adjusted to the press-fitting angle position.

[0026] A feed port 11 is provided on one side of the working cylinder 10, so that the press-fitting cavity 12 is connected to the outside through the feed port 11 to facilitate the placement of parts. A scale 13 is also marked on the side wall of the working cylinder 10. The scale 13 is placed on the side of the feed port 11 to facilitate the operator to operate the bolt 32 when the crossbeam press-fitting sleeve 20 is pressed into the distance.

[0027] Combined with reference Figure 3 , place the ball joint 2 on the side of the connecting rod 1 into the press-fitting cavity 12, select the corresponding press-fitting sleeve 20 according to the different models and sizes of the ball joint 2, use the tool to turn the bolt 32 to make the lower end of the bolt 32 contact the groove 22, press the ball joint 2 with the press-fitting sleeve 20, continue to turn the bolt 32 to push the ball joint 2 out of the mounting hole of the connecting rod 1, and finally use a special caliper to take out the ball joint 2. The installation operation of the ball joint can also be completed in reverse, first pre-install the ball joint 2 with a caliper, and then use the press-fitting sleeve 20 to push it into the connecting rod 1. Compared with the original mechanical press, this replacement tool is small in size and easy to carry. The operator can carry it outside the production workshop and disassemble and repair damaged parts on site.
