In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In order to facilitate the introduction of the structure and the principle of the present invention, in the following embodiments, the plug is used as a part to be assembled.

As shown in fig. 1 to 5, the E-shaped split retainer assembling jig of the present embodiment includes a positioning block 1, a guide pin 4, and a pressing rod 6. The upper end of the positioning block 1 is provided with a positioning section 10, and the positioning section 10 is downwards adjacent to a limiting section 14 which is radially enlarged. The outer diameter of the positioning section 10 is slightly smaller than the positioning hole 20 at the lower end of the plug 2, so that the plug 2 can be quickly and accurately fixed on the positioning block 1.

The guide pin 4 is substantially cylindrical and comprises a guide section 42 and an expansion section 44, the guide section 42 being located at the end remote from the locating block 1. Referring to fig. 3, a guide hole 40 matched with the cylindrical head 22 at the upper end of the plug 2 is formed in the end face of the expansion section 44, the guide pin 4 is connected to the upper end of the plug 2 at the initial assembly position, and the E-shaped split retainer ring 5 is placed on the guide section 42 of the guide pin 4. To better facilitate the movement of the E-shaped split washer 5, the guide section 42 may be tapered, preferably conical, in the direction away from the positioning block 1. The E-shaped split retainer ring 5 moves from the guide section 42 to the expanding section 44, the outer diameter of the expanding section 44 is larger than that of the guide section 42, the E-shaped split retainer ring 5 expands outwards, and in order to ensure that the E-shaped split retainer ring 5 expands uniformly, the expanding section 44 is preferably processed into a cylindrical shape.

The pressure lever 6 is arranged above the guide pin 4, the pressure lever 6 is tubular, an inner hole 60 is arranged at the lower end of the pressure lever 6, and the aperture of the inner hole 60 is larger than the outer diameter of the expansion section 44 of the guide pin 4. The pressing rod 6 is used for applying thrust to the E-shaped split retainer ring 5 and vertically pushing the E-shaped split retainer ring 5 downwards into the clamping groove 24 in the upper end of the plug 2. The pressure lever 6 can be manual or pneumatic. For example, the pressing rod 6 is fixed on a pneumatic jig, and the pressing rod 6 automatically moves downwards when a corresponding button is pressed. In the embodiment, the pressure lever 6 is driven manually, and the upper end of the pressure lever 6 can be further connected with a handle 7, and the handle 7 is convenient to grasp.

The E-shaped split washer assembling clamp provided by the embodiment has the following specific using process: the positioning block 1 is horizontally arranged, and the positioning section 10 is ensured to be upward. The positioning hole 20 of the plug 2 faces downwards, the plug 2 is vertically placed on the positioning block 1, and the lower end face 26 of the plug 2 abuts against the shaft shoulder 12 formed by the positioning section 10 and the limiting section 14. The nut 3 is sleeved on the plug 2, and the lower end face of the nut 3 is stopped on the boss 16 of the positioning block 1. The guide pin 4 is vertically placed on the plug 2 such that the cylindrical head 22 at the upper end of the plug 2 is inserted into the guide hole 40 at the end of the guide pin 4. The E-shaped split retainer ring 5 is sleeved on the guide section 42 of the guide pin 4, and the pressing rod 6 is vertically placed on the E-shaped split retainer ring 5. The pressing rod 6 is pushed downwards by force, the E-shaped split retainer ring 5 is forced to move downwards along the guide section 42 by the pressing rod 6 and moves downwards to the expansion section 44, the E-shaped split retainer ring 5 expands outwards along with the expansion section 44, enters the clamping groove 24 at the upper end of the plug 2 after passing through the expansion section 44, and the expanded E-shaped split retainer ring 5 contracts and recovers, so that the plug 2 is clamped.

The foregoing has described the principles and advantages of the present invention, and it will be apparent to those skilled in the art that the foregoing embodiments are merely illustrative of the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art may still modify the technical solutions described in the foregoing embodiments or make equivalents to some or all of the technical features thereof upon reading this specification.
