[0026] The specific embodiments of the utility model are described in further detail in combination with the drawings.

[0027] Referring to Figures 1 to 4 The embodiment of the application provides a damper joint press-fitting tool, which comprises a support bottom plate 1, a press-fitting block 2, a positioning plate 4, a press-fitting head 8 and a press-fitting machine round table 6, two vertical rods 7 are arranged on the support bottom plate 1 along the width direction of the support bottom plate 1, the press-fitting block 2 is detachably arranged on the support bottom plate 1, the press-fitting block 2 is in clearance fit with the damper joint 3, the positioning plate 4 is located above the press-fitting block 2, the positioning plate 4 is slidably installed on the two vertical rods 7, a positioning hole is formed in the positioning plate 4, the positioning hole is detachably connected with the damper joint 3, the press-fitting head 8 is detachably arranged on the positioning plate 4, the press-fitting head 8 has a press-fitting hole at the bottom, which is matched with the upper end of the damper joint 3, the press-fitting machine round table 6 is located above the press-fitting head 8, and the press-fitting machine round table 6 is detachably connected with the press-fitting head 8.

[0028] It should be noted that the positioning plate 4 can slide out of the two vertical rods 7, so that the positioning plate 4 can be replaced, the size of the damper joint 3 is different for different models of dampers 10, and the size of the corresponding positioning hole is also different, therefore, different positioning holes are formed in the plurality of positioning plates 4 for different models of dampers 10, so that the damper joint 3 can be positioned.

[0029] In the above scheme, when the ear ring of the damper 10 is pressed to fit the damper joint 3, the ear ring of the damper 10 is placed in the pressing block 2, and then the damper joint 3 is placed on the ear ring of the damper 10, and then the corresponding positioning plate 4 is installed on the two vertical rods 7, the positioning plate 4 is pressed to make the upper end of the damper joint 3 inserted into the positioning hole, and then the pressing head 8 is sleeved on the upper end of the damper joint 3 through the pressing hole, and then the pressing machine is started, so that the pressing machine round table 6 moves downward, and the pressing head 8 moves through the positioning plate 4 to complete the pressing of the damper joint 3. Compared with the prior art, the angle of the joint does not need to be measured by the angle ruler before pressing, and the angle deviation of the damper joint 3 is avoided during the pressing process, and the installation error of the damper 10 is reduced.

[0030] In some possible embodiments, referring to Figure 1 With Figure 2 As shown in the figure, when the upper end of the damper joint 3 is inserted into the positioning hole, the upper end of the damper joint 3 protrudes out of the positioning hole, and when the pressing head 8 is installed on the damper joint 3, the pressing head 8 is sleeved on the upper end of the damper joint 3 through the pressing hole.

[0031] In the above scheme, the pressing head 8 is used to prevent damage to the upper end of the damper joint 3 during pressing of the damper joint 3, and the pressing hole at the bottom of the pressing head 8 is sleeved on the upper end of the damper joint 3 during the pressing process. When the pressing machine round table 6 moves downward, the pressure does not act on the upper end of the damper joint 3, which protects the damper joint 3.

[0032] In some possible embodiments, referring to Figure 1 With Figure 2 As shown in the figure, the pressing block 2 is in a cylindrical structure, and the pressing block 2 is provided with an arc-shaped notch from top to bottom to form a support table. The ear ring of the damper 10 is in clearance fit with the through hole at the center of the pressing block 2, and the support table is used to support the ear ring of the damper 10.

[0033] In the above scheme, when the ear ring of the damper 10 is pressed to fit the damper joint 3, the ear ring at one end of the damper 10 is placed in the pressing block 2, and the ear ring is overlapped on the support table, so that the damper 10 is in a horizontal state, avoiding deviation during pressing.

[0034] In some possible embodiments, the included angle between the positioning hole and the length direction of the positioning plate 4 is 5°.

[0035] It should be noted that when the damper joint 3 is installed at 5°, during the operation of the damper 10, when forces from different directions (such as bumping forces, vibration impact forces, etc. during vehicle driving) are received, the transmission path of the forces at the connecting part of the damper joint 3 and the ear ring and the entire damper system will change in a certain way, which can make the stress more evenly distributed on the related parts, reduce the occurrence of local stress concentration. Stress concentration can cause premature fatigue damage to the parts. Installing at 5° helps to improve the overall strength and durability of the parts and prolong the service life of the damper.

[0036] In the design of vehicles or equipment, the installation space of the damper 10 is often limited, and the 5° angle setting of the damper joint 3 is determined on the premise of considering the layout of other surrounding parts and the installation space. It can meet the movement freedom required for the damper 10 to normally perform its function, and it can be reasonably installed in a limited space without space conflicts with other parts.

[0037] In some possible embodiments, referring to Figure 1 and Figure 2 , the positioning plate 4 is provided with a shaft sleeve 9 at both ends in the length direction, and the two shaft sleeves 9 are respectively sleeved on the two vertical rods 7. The shaft sleeve 9 is in sliding connection with the vertical rod 7, and the shaft sleeve 9 is used to reduce the sliding friction between the positioning plate 4 and the vertical rod 7, so as to facilitate the installation and disassembly of the positioning plate 4.

[0038] In some possible embodiments, referring to Figure 1 and Figure 2 , the support base plate 1 is also provided with a detachable support block 5, and the support block 5 is used to support the end of the damper 10 away from the pressing block 2.

[0039] In the above scheme, the support block 5 has a plurality of support blocks 5, and the selection of the support block 5 is determined according to different dampers 10. The support block 5 and the support table are used to horizontally support the damper 10, and at the same time, the support block 5 is also used to limit the left and right directions of the damper 10, so as to avoid the left and right deviation of the damper 10 when the ear ring of the damper 10 is pressed to install the damper joint 3.

[0040] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
