[0025] In order to better explain the present invention for easy understanding, the following will describe the present invention in detail through specific implementation manners in combination with the drawings.

[0026] It should be noted that all the directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0027] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] The present utility model provides an auxiliary device for interference fit, as Figures 1 to 4 shown, which includes a base 30. A placement area 31 is provided on the base 30. A slider 32 is slidably installed on one side of the placement area 31. The slider 32 is driven by a driving device. The iron frame 10 and the guide paper board 20 to be assembled together are placed on the placement area 31. Then, the driving device drives the slider 32 to move, so that relative movement occurs between the iron frame 10 and the guide paper board 20, thereby interference-fitting the fixing claws 21 on the guide paper board 20 with the mounting holes 11.

[0030] In this embodiment, to limit the guide paper board 20 and push the iron frame 10 to move, in order to ensure that the guide paper board 20 can remain stationary when the slider 32 pushes the iron frame 10 to move, a step 33 is provided on the side of the placement area 31 relative to the slider 32. The step 33 limits the guide paper board 20 to prevent the guide paper board 20 from moving synchronously when the slider 32 pushes the iron frame 10 to move.

[0031] As Figure 5 and Figure 6 shown, the driving device includes a cam 34. The base 30 is rotatably installed with a cam 34 on the side of the slider 32 relative to the placement area 31. The side surface of the cam 34 contacts the slider 32. Rotating the cam 34 can push the slider 32 to move. The slider 32 moves to push the iron frame 10 to move, completing the assembly.

[0032] Specifically, in order to make the movement of the slider 32 more stable, a chute 35 is provided on the base 30 at the position corresponding to the slider 32. A return spring 36 is arranged in the chute 35. After the cam 34 pushes the slider 32 to complete the assembly and rotates the cam 34 in the reverse direction, at this time, under the action of the return spring 36, the slider 32 will move in the reverse direction, thus facilitating the removal of the assembled iron frame 10 and guide paper board 20 for the next assembly.

[0033] A limit block 37 is installed at the position of the base 30 corresponding to the slider 32. The limit block 37 presses on the slider 32, and the slider 32 is inserted and matched with the limit block 37. The limit block 37 is detachably connected to the base 30 by bolts. The limit block 37 can ensure that the slider 32 slides stably on the base 30, ensuring the stable operation of the device.

[0034] As Figure 3 and Figure 4 shown, a handle 40 in the shape of an L is rotatably installed at the position of the base 30 corresponding to the cam 34. The cam 34 is sleeved and clamped on the handle 40. Rotating the handle 40 can drive the cam 34 to rotate. A retaining spring 41 for resetting is installed at the rotating part of the handle 40 and the base 30. After rotating the handle 40 to make the cam 34 work and then releasing the handle 40, under the action of the retaining spring 41, the handle 40 rotates in the reverse direction, and thus the next operation can be carried out, achieving a semi-automatic effect.

[0035] As Figure 3 shown, a handle 42 is sleeved on the handle 40, which is convenient for the user to grasp the handle 40 and makes it more comfortable and convenient to use.

[0036] As Figure 5 and Figure 6 shown, by reasonably setting the size of the cam 34, after the cam 34 rotates in place, the slider 32 can just assemble the iron block 10 and the guide paper board 20 in place, thereby effectively improving the work efficiency and ensuring the consistency of product quality.

[0037] It should be understood that the above description of the specific embodiments of the present invention is only for explaining the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the above specific embodiments. Any changes or modifications made within the scope of the claims of the present invention should be covered by the protection scope of the present invention.
