Description

Technical Field

[0001] This utility model discloses an assembly fixture, belonging to the technical field of snap ring assembly fixtures, specifically relating to a snap ring assembly fixture device. Background Technology

[0002] A retaining circlip, also known as a retaining ring or spring retainer, is a common mechanical part used primarily to secure components on a shaft or prevent bearings and other parts from sliding axially. It is typically made of an elastic material and can be tightly embedded into a shaft groove or hole using its own elastic force, thus providing a limiting function. There are various types of retaining circlips.

[0003] A shaft retaining ring needs to be installed at the end of the axial rolling head and the housing. However, due to the design of the keyway of the end, it is impossible to loosen the retaining ring slightly with retaining ring pliers and put it into the pre-machined groove. This often leads to a lot of wasted assembly time because it is difficult to install. Or, the retaining ring, after being stretched, often loses its elasticity and undergoes plastic deformation, making it unable to be tightly embedded in the keyway by its own elastic force.

[0010] In a further embodiment, the housing is provided with a plurality of equidistant arrayed loop holes.

[0011] In a further embodiment, the shank diameter of the limiting sleeve matches the inner hole of the workpiece, and its outer shape matches the groove shape of the keyway of the workpiece.

[0012] In a further embodiment, the limiting sleeve is provided with a groove that matches the chamfer.

[0013] In a further embodiment, the limiting sleeve has a tapered structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 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.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] A snap ring assembly fixture includes: a press-fit sleeve 1, a retaining ring 2, a limiting sleeve 3, a housing 4, a tail shank 5, and a sleeve 6.

[0029] In one embodiment, such as Figures 1 to 4 As shown, one end of the tail shank 5 passes through one side of the housing 4 and is engaged with the bottom of the housing 4, and extends to the other side of the housing 4. One end of the limiting sleeve 3 is sleeved inside one end of the tail shank 5. One end of the press-fit sleeve 1 is sleeved on the other end of the limiting sleeve 3. The retaining ring 2 is sleeved on the other end of the limiting sleeve 3. The sleeve 6 is located on one side of the housing 4.

[0030] In one embodiment, such as Figures 1 to 4 As shown, the tail shank 5 and the bottom of the limiting sleeve 3 are provided with mutually cooperating slots and blocks.

[0031] In one embodiment, such as Figures 1 to 4 As shown, a scale is provided on the outer side of the housing 4.

[0032] In one embodiment, such as Figures 1 to 4 As shown, the housing 4 has several loop-shaped holes arranged in an equidistant array.

[0033] In one embodiment, such as Figures 1 to 4 As shown, the shank diameter of the limiting sleeve 3 matches the inner hole of the workpiece, and its outer shape matches the groove shape of the keyway of the workpiece.

[0034] In one embodiment, such as Figures 1 to 4 As shown, the limiting sleeve 3 is provided with a groove that matches the chamfer.

[0035] In one embodiment, such as Figures 1 to 4 As shown, the limiting sleeve 3 has a tapered structure.

[0036] Working principle: The main working principle is to manufacture a limiting sleeve 3. The diameter of the limiting sleeve 3 matches the inner hole of the workpiece, and the outer shape is made to match the keyway of the workpiece. Because the keyway of the product has a large C-angle, the limiting sleeve 3 is made to match the chamfer, so that the limiting sleeve 3 fits tightly with the product shape without gaps. The limiting sleeve 3 is made with a tapered structure to facilitate the insertion of the retaining ring 2. The press-fitting sleeve 1 is placed on the limiting sleeve 3 and the retaining ring 2, and the press-fitting sleeve 1 is struck with external force to make the retaining ring 2 fall onto the outer diameter of the limiting sleeve 3. The press-fitting sleeve 1 is removed. The sleeve 6 is placed on the limiting sleeve 3 and the retaining ring 2, and the sleeve 6 is struck to deform the retaining ring and make it fall into the groove of the product.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
