[0046] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0047] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0048] Unless otherwise specified, the exemplary embodiments / examples shown will be understood to provide exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various embodiments / examples may be additionally combined, separated, interchanged, and / or rearranged.

[0049] In the drawings, cross-hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement regarding the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences may be performed in an order different from that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. Moreover, the same reference numerals denote the same components.

[0050] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component may be directly on the other component, directly connected to or directly coupled to the other component, or there may be an intermediate component. However, when the component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. For this reason, the term "connection" may refer to a physical connection, an electrical connection, etc., and may or may not have an intermediate component.

[0051] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "over", "higher", and "side (e.g., as in "side wall")" to describe the relationship of one component to another (other) component as shown in the figures. In addition to the orientation depicted in the figures, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the figures is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0052] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but it does not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus they are used to explain the inherent deviations of measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.

[0053] Figure 1 is a schematic structural view of a snap ring assembling device according to an embodiment of the present disclosure. Figure 2 and Figure 3 is a schematic structural view of the snap ring assembling device from another angle according to an embodiment of the present disclosure. Figure 4 is a schematic structural view of a jig 100 according to an embodiment of the present disclosure.

[0054] As Figures 1 to 4 shown, when the snap ring assembling device of the present disclosure is in use, it can install a snap ring into a hole of an automotive transmission. Specifically, a plurality of holes may be formed in the housing of the automotive transmission, and these holes may have the same inner diameter or different inner diameters; correspondingly, the sizes of the snap rings may also be the same or different. That is, the size of the snap ring is set to correspond to the size of the hole.

[0055] At the side wall at a preset position in the axial direction of these holes, an annular groove can be provided, and this annular groove is the snap ring groove. When the snap ring is installed in the hole, the snap ring can be in close contact with the bottom wall surface of the snap ring groove under the action of its own elastic force.

[0056] Structurally speaking, the snap ring assembly device of the present disclosure may include components such as a jig 100, a connecting plate 200, a first base 300, a second base 400, a pressing head 500, and a clamping device 600.

[0057] As Figure 4 shown, the jig 100 of the present disclosure is used to store the snap ring to be assembled. Specifically, the jig 100 of the present disclosure is generally cylindrical in shape, and at least part of the inner peripheral surface of the jig 100 is a conical surface. In other words, the jig 100 has an axial direction, and in actual use, this axial direction can be set as the vertical direction. At this time, the axial direction of the hole of the housing of the automotive transmission is also set as the vertical direction.

[0058] When the jig 100 of the present disclosure is in use, on the one hand, the axial direction of the jig is set as the vertical direction, and on the other hand, at least part of the inner diameter of the jig 100 gradually decreases in the direction from top to bottom. In other words, the conical surface of the inner peripheral surface of the jig of the present disclosure is set as an inverted cone shape.

[0059] In addition, the inner peripheral surface of the jig 100 of the present disclosure may also include a cylindrical surface. Specifically, the upper end and / or the lower end of the conical surface may be provided with this cylindrical surface. Correspondingly, the diameter of the cylindrical surface provided at the upper end of the conical surface is the same as the inner diameter of the upper end of the conical surface, and the diameter of the cylindrical surface provided at the lower end of the conical surface is the same as the diameter of the lower end of the conical surface. Thus, the inner peripheral surface of the jig 100 of the present disclosure will not affect the normal downward movement of the snap ring.

[0060] The outer peripheral surface of the jig 100 of the present disclosure is formed in the form of a stepped cylindrical surface. Specifically, the outer peripheral surface of the jig 100 includes a first diameter portion 110 and a second diameter portion 120. Among them, the first diameter portion 110 has a first diameter, the second diameter portion 120 has a second diameter, and the first diameter portion 110 is located above the second diameter portion 120. Thus, the outer peripheral surface of the jig 100 of the present disclosure is formed into a structure with a larger upper part and a smaller lower part, which is beneficial to inserting the lower end of the jig into the hole of the housing of the automotive transmission.

[0061] Those skilled in the art should be aware that when installing circlips of different sizes into holes of different sizes, fixtures 100 of different sizes can be used to achieve this. That is to say, at this time, a suitable fixture can be selected, and the second diameter of the fixture is made the same as or slightly smaller than the inner diameter of the hole, so that the lower end of the fixture 100 can be conveniently inserted into the hole of the housing of the automotive transmission.

[0062] As Figure 4 shown, a positioning member 130 is provided on the second diameter portion 120 of the present disclosure. The positioning member 130 is used to cooperate with the groove on the inner wall surface of the hole, so that the fixture 100 is positioned in the circumferential direction (i.e., the circumferential direction of the hole) relative to the hole. Thus, the circlip assembled by the circlip assembling device of the present disclosure can have a fixed opening direction.

[0063] In a preferred embodiment, the positioning member 130 is provided at the upper end of the second diameter portion 120, that is, the positioning member 130 is provided close to the lower end of the first diameter portion. Thus, when at least a part of the lower end of the fixture 100 is inserted into the hole of the housing of the automotive transmission, the positioning member 130 can be located in the notch at the upper end of the hole of the housing of the automotive transmission, and correspondingly, a notch with a relatively large size will not be formed in the hole of the housing of the automotive transmission.

[0064] In a preferred embodiment, the connection between the first diameter portion 110 and the second diameter portion 120 is formed as a stepped surface, so that the size of the fixture 100 inserted into the hole can be controlled by the cooperation of this stepped surface and the end surface of the hole of the housing of the automotive transmission.

[0065] More preferably, the dimension in the axial direction of the second diameter portion (i.e., the height of the second diameter portion) can be set differently according to the position of the circlip groove. In other words, even when installing a circlip in a hole with the same diameter, due to the different positions of the circlip groove along the axial direction of the hole, fixtures 100 with different heights of the second diameter portion can be selected.

[0066] A limiting block 140 is provided on the first diameter portion 110, and at least a part of the limiting block 140 is located in the inner cavity of the fixture 100; in a preferred embodiment, at least a part of the limiting block 140 can extend along the axial direction of the fixture 100 in the inner cavity of the fixture 100. Thus, when the circlip is placed inside the fixture 100, the limiting block 140 can be located in the circumferential opening of the circlip, so that the circlip can be positioned in the circumferential direction; correspondingly, combined with the positioning function of the positioning member 130, when the circlip is installed in the hole of the automotive transmission, the direction of the circumferential opening of the circlip can be determined.

[0067] In the present disclosure, at least two clamping blocks 150 are further provided on the first diameter portion 110. Thus, the fixture 100 of the present disclosure can be conveniently operated by the jaw device. In one embodiment, a jaw device can be installed on the robotic arm, and the jaw device can clamp the fixture 100 through the clamping blocks 150 to achieve automated handling and release of the fixture 100. In addition, the fixture 100 of the present disclosure can also be clamped by the clamping device 600 and driven to move.

[0068] An avoidance groove 160 is formed in the first diameter portion 110, and the opening of the avoidance groove 160 faces the upper end of the fixture 100. Correspondingly, through the setting of the avoidance groove 160, the snap ring can be conveniently placed in the fixture 100. Specifically, when manually placing the snap ring by a worker, the snap ring can be pinched with fingers and placed in a horizontal state, and then the snap ring is slowly lowered. At this time, the fingers can be located in the avoidance groove 160, and the snap ring can be located at a preset position within the fixture 100.

[0069] In the present disclosure, the placement of the snap ring can also be achieved by automated equipment such as jaws. Specifically, after the jaws clamp the snap ring, the snap ring is kept in a horizontal state, and then the snap ring is slowly lowered. At this time, the jaws can be located in the avoidance groove 160, and the snap ring can be located at a preset position within the fixture 100.

[0070] An installation hole is formed in the first diameter portion 110 of the present disclosure, and a magnet 170 is provided in the installation hole. That is to say, after the snap ring of the present disclosure is arranged inside the fixture 100, the snap ring can be fixed on the magnet 170 through the adsorption of the magnet 170 to prevent the attitude change of the snap ring.

[0071] In a preferred embodiment, a plurality of installation holes are provided, and correspondingly, a plurality of magnets 170 are also provided. More preferably, these installation holes are arranged in a plane perpendicular to the axis of the fixture 100. Correspondingly, the snap ring can be adsorbed by the magnet 170 and held on this plane.

[0072] In the present disclosure, a plurality of installation holes are arranged to be distributed along the circumferential direction of the fixture 100. For example, they are arranged to be non-uniformly distributed along the circumferential direction of the fixture 100, so that the positions of the installation holes can avoid the opening of the snap ring and the position of the avoidance groove.

[0073] Generally speaking, when the fixture 100 of the present disclosure is in use, a retaining ring can be placed inside the fixture 100 using a robotic arm or manually, and then the retaining ring will be adsorbed by the magnet 170 and held on a certain horizontal plane. Preferably, the plane where the retaining ring is located can intersect with the conical surface, and thus the action of pressing down the retaining ring can be conveniently achieved. After the retaining ring is placed inside the fixture 100, the second diameter portion 120 of the fixture 100 can be inserted into the hole of the automotive transmission by means of a robotic arm or manual handling, and the pressing of the retaining ring can be achieved through components such as the pressing head 500 described below.

[0074] As Figures 1 to 3 shown, the connecting plate 200 of the present disclosure can be formed as a plate-like component. In actual use, the connecting plate 200 can be fixed to components such as a frame or a robotic arm, so that it can be driven by the robotic arm to reach a preset position.

[0075] The first base 300 is arranged to be movable relative to the connecting plate 200 in a first direction; in the present disclosure, this first direction is the vertical direction, that is to say, the first base 300 of the present disclosure can be driven to move downward or upward.

[0076] Specifically, the connecting plate 200 of the present disclosure is provided with first guide rails 210, and two of the first guide rails 210 can be provided. These two first guide rails 210 are both vertically arranged, so that the movement of the first base 300 can be guided through the first guide rails 210.

[0077] The first base 300 of the present disclosure can be driven to move by a first driving device 310. Specifically, the first driving device 310 can be a linear driving mechanism such as a cylinder, a hydraulic cylinder or an electric cylinder. Moreover, the first driving device 310 can be directly or indirectly fixed to the connecting plate 200, and the first driving device 310 can be connected to the first base 300 so that when the first driving device 310 acts, the first base 300 can generate a lifting action.

[0078] In a preferred embodiment, the first driving device 310 can be connected to the first base 300 through a floating component, so that the first base 300 can have a certain floating effect to prevent damage to the retaining ring when pressing in the retaining ring. In a specific embodiment, the floating component can be a spring or an elastic component.

[0079] The pressing head 500 is arranged on the first base 300 so that the pressing head 500 generates a movement in the first direction through the movement of the first base 300 to eject the retaining ring in the fixture 100 to the outside of the fixture 100. In a preferred embodiment, the pressing head 500 can be fixed to the first base 300 through a connecting rod.

[0080] Specifically, as Figures 1 to 3 shown, the indenter 500 of the present disclosure is formed into a cylindrical structure, and the indenter 500 has an opening in the circumferential direction, and the size of the opening in the circumferential direction is larger than the size of the limiting block 140 located in the inner cavity of the jig 100.

[0081] Those skilled in the art should be aware that since the snap rings have different diameters, correspondingly, the indenter 500 can also have different outer diameters and inner diameters. For example, when installing snap rings with different diameters, an indenter 500 corresponding to the snap ring can be selected to cooperate with the snap ring and push the snap ring to act.

[0082] In one embodiment, a limiting component 220 is further provided on the connecting plate 200, and the limiting component 220 can be provided at both ends of the first guide rail 210, so as to be able to limit the highest position of the upward movement and the lowest position of the downward movement of the first base 300.

[0083] In the present disclosure, after the snap ring is arranged in the jig 100, the first driving device 310 can be controlled to act, and the indenter 500 is moved downward, so that the indenter 500 is inserted into the interior of the jig 100. At this time, the opening of the indenter 500 needs to be aligned with the limiting block 140 of the jig 100, so as to prevent the limiting block 140 from affecting the downward pressing action of the indenter 500, or preventing the limiting block 140 from touching the indenter 500 and damaging the jig 100 or the indenter 500.

[0084] When the indenter 500 is further pressed downward, the lower end surface of the indenter 500 can be in pressure contact with the upper end surface of the snap ring and push the snap ring downward. At this time, since the inner diameter of the jig 100 gradually decreases, correspondingly, the outer diameter of the snap ring will continuously become smaller, and the opening of the snap ring will also become smaller. At this time, the limiting block 140 can also be set such that in the direction from top to bottom, its circumferential dimension (i.e., the dimension along the circumferential direction of the jig 100) also gradually decreases, so that the limiting block 140 does not affect the downward movement of the snap ring.

[0085] Referring again to Figures 1 to 3 , the second base 400 of the present disclosure is arranged to be movable relative to the first base 300 in a first direction. That is to say, the second base 400 of the present disclosure can be driven to generate a lifting movement relative to the first base 300.

[0086] For example, the second driving device 410 can be a linear driving mechanism such as a cylinder, a hydraulic cylinder or an electric cylinder. Moreover, the second driving device 410 can be directly or indirectly fixed to the first base 300, and the second driving device 410 can be connected to the second base 400, so that when the second driving device 410 acts, the second base 400 can generate a lifting action.

[0087] The clamping device 600 is arranged on the second base 400. Specifically, the clamping device 600 may include two jaws capable of relative movement, namely, a first jaw and a second jaw. Preferably, the jaws can be driven to move in the horizontal direction. At this time, the two jaws can approach each other or move away from each other, so that the fixture 100 can be clamped and released by the jaws.

[0088] For example, the first jaw and the second jaw respectively cooperate with the clamping block 150 of the fixture 100 to support the fixture 100, and the fixture 100 is operated by the clamping device 600. After the circlip leaves the fixture 100, it enters the circlip groove opened on the inner wall surface of the hole.

[0089] Similarly, during the movement of the second base 400 of the present disclosure, it can be guided by the second guide rail arranged on the first base 300. Preferably, the second guide rail can also be arranged in two, and both of the two second guide rails are arranged vertically.

[0090] Moreover, during the movement of the second base 400, its highest upward movement position and lowest downward movement position can also be limited by the limiting device. More preferably, the second driving device 410 is connected to the second base 400 through a floating member, so that the second base 400 can have a certain floating effect. In a specific embodiment, the floating member can be a spring or an elastic member.

[0091] In the present disclosure, when the circlip is being pressed down, the clamping device 600 can clamp the fixture 100 and drive the fixture 100 to lift through the second driving device 410; then, the circlip is continuously pressed down and the fixture 100 is continuously lifted. By using the relative movement of the two, the circlip will be pushed out of the fixture 100 and pressed into the appropriate position of the automotive transmission.

[0092] After the circlip is assembled, the clamping device 600 can release the fixture 100, and the first driving device 310 acts to drive the first base 300 and the second base 400 to move upward, so that the pressing head 500 leaves the fixture 100. Then, a robot or other handling mechanism transports the fixture 100 back to the standby position to wait for the assembly of the next circlip product.

[0093] Thus, the circlip assembling device of the present disclosure can realize the automatic press-fitting of the circlip, that is, the circlip can be pressed into the hole of the housing of the automotive transmission, and accordingly, a large amount of manpower and time can be saved, and the factory efficiency can be greatly improved.
