[0023] Example:

[0024] like Figure 1-Figure 3 As shown, this embodiment provides an auxiliary press-fitting device, including:

[0025] The lower positioning tool is used to match and install the click plate 1 and the guide sleeve 2 on the upper end of the lower positioning tool, so that the guide sleeve 2 is located below the installation hole of the click plate 1, and the click plate spring 3 is stably placed above the installation hole of the click plate 1, and the click plate 1, the guide sleeve 2 and the click plate spring 3 are quickly positioned in an installation manner from bottom to top;

[0027] The upper pressing mechanism is located above the lower positioning tooling, and the upper pressing mechanism is slidably connected to the support frame 4 along the vertical direction, so that the guide sleeve 2 and the pressing disk spring 3 can be clamped in the mounting hole of the pressing disk 1 through the downward pressure of the upper pressing mechanism. In practice, the upper pressing mechanism only needs to slide downward and press the pressing disk 1, the guide sleeve 2 and the pressing disk spring 3 to achieve the clamping of the guide sleeve 2 and the pressing disk spring 3 on the pressing disk 1. It is simple and efficient, and will no longer cause harm to the hands of employees.

In practice, the positioning block 7 is controlled to make the positioning slide groove 5 slide along the positioning slide groove 5 in the vertical direction, which can drive the upper pressing mechanism to slide up and down, and at the same time can ensure that the upper pressing mechanism is accurately aligned with the pressing plate (1), guide sleeve (2) and pressing plate spring (3) on the upper pressing mechanism, so as to ensure the controllability of the operation. After the final pressing is completed, the tension spring can drive the upper pressing mechanism to slide up and reset.

[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that the auxiliary pressing device also includes a first adjusting arm 8, a second adjusting arm 9 and a pressing handle 10. The upper end of the first adjusting arm 8 is rotatably connected to the upper end of the support frame 4, and the lower end of the second adjusting arm 9 is rotatably connected to the upper end of the positioning block 7. The lower end of the first adjusting arm 8 and the upper end of the second adjusting arm 9 both extend in a direction away from the vertical slider 6, and the lower end of the first adjusting arm 8 is rotatably connected to the upper end of the second adjusting arm 9; the pressing handle 10 is installed in the middle of the first adjusting arm 8, such as Figure 1 As described above, in practice, by pressing the handle 10 to press the first adjusting arm 8 toward the positioning slot 5, the second adjusting arm 9 can be moved downward, and then the upper pressing mechanism is driven to move downward through the positioning block 7, which is simple and convenient to operate.

[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that the upper pressing mechanism includes an upper pressing mounting plate 11 connected to the lower end of the positioning block 7 and three pressing limit posts 12 connected to the lower end of the upper pressing mounting plate 11, the three pressing limit posts 12 respectively corresponding to the three mounting holes of the pressing plate 1, the lower end of each pressing limit post 12 is provided with an annular limiting groove 1201 for matching the pressing plate spring 3, and the lower end of each pressing limit post 12 is also provided with a vertical avoidance groove 1202 for facilitating the three claws of the guide sleeve 2 to pass through the middle of the pressing plate spring 3. In practice, the pressing limit post 12 presses the pressing plate spring 3 to compress the pressing plate spring 3, and then the three claws of the guide sleeve 2 pass through the pressing plate spring 3 to realize the clamping of the pressing plate spring 3, which is simple and effective; the lower end of the tension spring is connected to the upper pressing mounting plate 11 to ensure that the tension spring can drive the upper pressing mechanism to reset.

[0031] As a preferred implementation scheme in this embodiment, it needs to be further explained that the pressure limit column 12 includes a sliding sleeve and a sliding column, a first through hole is provided in the middle of the sliding sleeve, the lower part of the sliding column is inserted into the first through hole, and a limiting ring abutting against the upper end of the sliding sleeve is provided at the upper end of the sliding column. The diameter of the limiting ring is larger than the first through hole, and a connecting ring is provided at the upper end of the sliding sleeve. The connecting ring is connected to the upper press-fit mounting plate 11 by bolts to ensure the installation of the sliding sleeve and the sliding column on the upper press-fit mounting plate 11; the annular limit groove 1201 is opened On the inner side of the lower end of the sliding sleeve, three vertical avoidance grooves 1202 are formed on the outer wall of the lower end of the sliding column, and the sliding sleeve outside the three vertical avoidance grooves 1202 are provided with outer avoidance openings 1203 which are convenient for the claws to clamp the click disk spring 3 when it elastically resets from the inside to the outside of the click disk spring 3. In practice, after the click disk spring 3 is compressed, the three claws of the guide sleeve 2 pass through the click disk spring 3, and then reset from the inside to the outside of the click disk spring 3 under the elastic effect of the claws themselves, thereby realizing the clamping of the click disk spring 3.

[0032] As a preferred implementation scheme in this embodiment, it needs to be further explained that the lower positioning tool includes a base 13 and a positioning plate 14 for cooperating in the installation of the click plate 1 and the guide sleeve 2. The positioning plate 14 is elastically connected to the base 13 in the vertical direction, so that in the actual downward pressing process of the upper pressing mechanism, the positioning plate 14 can be elastically moved downward to a certain extent, which has a buffering effect and avoids the downward pressure of the upper pressing mechanism from being poorly controlled, resulting in damage to the click plate 1, the guide sleeve 2 or the click plate spring 3. The lower end of the support frame 4 is installed on the base 13 on one side of the positioning plate 14, which does not affect the stability of the upper pressing mechanism.

[0033] As a preferred implementation scheme in this embodiment, it needs to be further explained that a plurality of limiting holes are arranged on the positioning plate 14, and a plurality of T-shaped limiting columns 15 are connected to the base 13. The vertical section of each T-shaped limiting column 15 matches and passes through a limiting hole, and the limiting ring at the upper end of the T-shaped limiting column 15 realizes the limitation of the positioning plate 14. A return spring is sleeved on the outside of the vertical section of each T-shaped limiting column 15, and the two ends of the return spring are respectively abutted against the base 13 and the positioning plate 14. Then, when the upper pressing mechanism is pressed down, the positioning plate 14 can realize elastic downward pressure, thereby avoiding the upper pressing mechanism from failing to control the downward pressure, causing damage to the pressing plate (1), the guide sleeve (2) or the pressing plate spring (3), thereby achieving a buffering effect. After the pressing is completed, the return spring can drive the positioning plate 14 to reset.

[0034] As a preferred implementation scheme in this embodiment, it needs to be further explained that a guide sleeve positioning member 16, such as a simple limiting ring, is provided at the upper end of the positioning plate 14 to realize the positioning of the guide sleeve 2. The style of the guide sleeve positioning member 16 can adopt the existing positioning member, and this embodiment does not make specific restrictions.

[0035] As a preferred implementation scheme in this embodiment, it needs to be further explained that two inverted U-shaped handles 17 are installed on the upper end of the positioning plate 14 to facilitate the transportation of the entire device and improve convenience.
