[0006] In the aforementioned shock-absorbing rocker arm assembly fixture, the central protrusion at the upper end of the mold base plate forms the positioning mold, and press mounting holes are opened on both sides of the upper end of the mold base plate.

[0007] In the aforementioned shock-absorbing rocker arm assembly fixture, a first countersunk hole is formed at the center of the upper end of the positioning mold, and the first countersunk hole is rectangular.

[0008] In the aforementioned shock-absorbing rocker arm assembly fixture, a second countersunk hole is formed in the center of the first countersunk hole, and the second countersunk hole is rectangular.

[0009] In the aforementioned shock-absorbing rocker arm assembly fixture, each corner of the second countersunk hole is directly opposite each side of the first countersunk hole.

[0010] In the aforementioned shock-absorbing rocker arm assembly fixture, the center line of the arc-shaped groove is aligned with the first countersunk hole.

[0011] Because this utility model employs the aforementioned technology, it has the following positive effects compared to existing technologies:

[0012] (1) By using shock-absorbing rocker arm assembly fixtures, the problem of existing operators being unable to properly fix products can be solved.

[0013] (2) By using the shock-absorbing rocker arm assembly fixture, the dimensional tolerance of the rubber rod after assembly can be effectively controlled.

[0014] (3) The workpiece of the shock-absorbing rocker arm to be assembled can be placed directly on the shock-absorbing rocker arm assembly fixture, eliminating human intervention and quickly placing it, while effectively improving production capacity and efficiency. Attached Figure Description

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Please see Figures 1 to 4The image shows a preferred embodiment of a shock-absorbing rocker arm assembly fixture, comprising: a mold base plate 1 and a raised support block 5. The upper end of the mold base plate 1 protrudes to form a positioning mold 2, and a first countersunk hole 3 is formed at the upper end of the positioning mold 2. A second countersunk hole 4 is also formed within the first countersunk hole 3. The raised support block 5 forms a certain distance from the mold base plate 1, and an arc-shaped groove 6 is formed at the upper end of the raised support block 5.

[0023] Based on the above, this utility model also has the following embodiments:

[0024] Furthermore, as a preferred embodiment, please continue to refer to... Figures 1 to 4 As shown, the central protrusion at the upper end of the mold base plate 1 forms the positioning mold 2, and press mounting holes 7 are opened on both sides of the upper end of the mold base plate 1. The mold base plate 1 is installed on the external press through the press mounting holes 7.

[0025] Furthermore, in a preferred embodiment, the mold base plate 1 is rectangular in shape, and the positioning mold 2 is rectangular in shape.

[0026] Furthermore, in a preferred embodiment, a first countersunk hole 3 is formed at the center of the upper end of the positioning mold 2. The first countersunk hole 3 is rectangular in shape and matches the outer frame of the shock-absorbing rocker arm workpiece 8 to be assembled.

[0027] Furthermore, in a preferred embodiment, a second countersunk hole 4 is formed in the center of the first countersunk hole 3. The second countersunk hole 4 is rectangular in shape and matches the inner support metal block 9 of the shock-absorbing rocker arm workpiece 8 to be assembled.

[0028] Furthermore, in a preferred embodiment, each corner of the second countersunk hole 4 is directly opposite each side of the first countersunk hole 3.

[0029] Furthermore, in a preferred embodiment, the centerline of the arc groove 6 is aligned with the first countersunk hole 3, and the arc groove 6 matches the round tube rocker arm of the shock-absorbing rocker arm workpiece 8 to be assembled.

[0030] In addition to the above, this utility model also has the following usage methods:

[0031] Please continue reading Figures 1 to 4 As shown, step one: install the mold base plate 1 onto the external press through the press mounting hole 7, thereby fixing the shock-absorbing rocker arm workpiece 8 to be assembled later. The press can preferably be a single-column vertical press.

[0032] Step 2: Place the support block 5 in front of the mold base plate 1. Place the shock-absorbing rocker arm workpiece 8 to be assembled on the mold base plate 1 and the support block 5. The outer frame of the shock-absorbing rocker arm workpiece 8 to be assembled is placed in the first countersunk hole 3. The round tube rocker arm of the shock-absorbing rocker arm workpiece 8 to be assembled can be placed in the arc groove 6 of the support block 5. In this way, the arc groove 6 allows the round tube rocker arm to have a better contact surface and can be laid flat, thereby eliminating the height difference.

[0033] Step 3: Place the rubber rod 10 inside the outer frame of the shock-absorbing rocker arm workpiece 8 to be assembled, and then place the inner support metal block 9 inside the rubber rod 10. Start the press to descend, pressing the inner support metal block 9 into the second countersunk hole 4. The first countersunk hole 3 is used to position the outer frame of the shock-absorbing rocker arm workpiece 8 to be assembled, ensuring the angle of the workpiece 8 and the installation depth of the inner support metal block 9. The second countersunk hole 4 is used to position the rubber rod 10 and the inner support metal block 9 at the angle and depth. This completes the assembly of one end of the shock-absorbing rocker arm workpiece 8.

[0034] Step 4: Repeat the above steps to complete the assembly of the other end.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.
