Embodiment Construction
[0032] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations therein are illustrative in nature and not intended to limit the present invention. invention.
[0033] Such as Figure 4 with Figure 5 As shown, an embodiment of the retaining ring installation and removal device proposed by the present invention. In this embodiment, the circlip installation and removal device is used to install or remove the circlip 100 for one shaft. In this embodiment, an existing shaft circlip 100 is taken as an example for illustration. The shaft circlip 100 has two trailing ends 101 , and each trailing end 101 is respectively provided with a pincer hole 102 . In this embodiment, the retaining ring insta...

The invention provides a retaining ring assembly and disassembly device. The retaining ring installation and disassemble device is used for assembling and disassembling a flexible retaining rings for a shaft, the flexible retaining rings for the shaft is provided with two traction ends, and clamp holes are formed in the traction ends. The retaining ring assembly and disassembly device comprises a frame body, a two-way screw rod and two traction blocks, wherein the two-way screw rod is rotatably arranged on the frame body, and two sections of external threads with opposite screwing directions are arranged on the two-way screw rod; the two traction blocks are connected onto the two-way screw rod in a threaded mode, and each traction block is provided with a threaded connecting portion and a traction head; a threaded hole is formed in each threaded portion, and the internal thread of the threaded hole is matched with the external thread of the two-way screw rod; each traction head is formed by the corresponding threaded connecting portion horizontally extending out of the frame body, and each traction head can be connected with the clamp hole. The retaining ring assembly and disassembly device overcomes the defect that existing straight tip installation pliers enable the retaining ring to generate additional deformation. The lever structure of the existing installation pliers is replaced by a screw pair, the labor is saved, meanwhile, the defect of non-self-locking of retaining ring pliers is also eliminated, the retaining ring obtains an arbitrary rolling-up diameter needed by assembly and disassembly conveniently through the screw pair, and therefore the whole operation process is more labor-saving and reliable.
Description
technical field [0001] The invention relates to a device for installing and dismounting a retaining ring. Background technique [0002] The shaft circlip is a widely used standard part. For a long time, the shaft circlip installation pliers are used for installation and disassembly. This kind of installation pliers often causes the accident that the circlip slips from the pliers mouth and hurts people. Moreover, the above-mentioned installation pliers are also specifically divided into straight mouth type and hook mouth type, and the straight mouth type installation pliers will cause additional deformation of the retaining ring (such as figure 1 shown), which brings certain difficulties to installation and disassembly. The hook mouth type installation pliers will increase the expansion force due to operation fatigue or the increase in the diameter of the retaining ring, and the operator will find it difficult to hold and operate (such as figure 2 shown). In order to solv...
