Description

Technical Field

[0001] The present invention relates to the technical field of clip spring installation, and in particular to a clip spring installation device. Background Art

[0002] A circlip, also called a retaining ring or a snap ring, is a type of fastener that is installed in the shaft groove or hole groove of a machine or equipment, and serves to prevent the axial movement of parts on the shaft or hole. Two clamping holes are usually provided on the circlip, and circlip pliers are generally used to expand or compress the circlip. After the circlip is placed in the specified position, the circlip pliers are loosened so that the circlip is engaged in the circlip groove, thereby achieving the installation of the circlip. However, when installing circlips in deep holes, it is difficult to expand and sleeve the circlip onto the rotating shaft because the circlip pliers are difficult to extend into the deep hole. In addition, it is difficult to observe the position of the circlip groove on the rotating shaft when installing the circlip in the deep hole. It is also difficult to align the position of the circlip during installation. The position of the circlip needs to be adjusted multiple times to achieve correct installation, and the installation operation is cumbersome. Therefore, a circlip installation device is needed to solve the above problems. Summary of the Invention

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-6 , the present invention provides a technical solution:

[0023] A retaining spring installation device includes a base plate 1, a support frame 2 and a tube body 3. The support frame 2 is installed on the base plate 1. A through hole is provided in the middle of the support frame 2. The tube body 3 can be detachably inserted into the through hole on the support frame 2. Handles 5 are connected to the two ends of the upper side of the tube body 3. The setting of the handles 5 facilitates the removal and placement of the tube body 3.

[0024] An installation component 4 for installing the retaining ring 11 is installed in the tube body 3, and the installation component 4 includes a ring body 41, a sleeve 42 and a driving rod 43. The ring body 41 is connected to the tube body 3 for sliding up and down, and the sleeve 42 is connected to the ring body 41. The driving rod 43 is connected to the tube body 3 for sliding up and down, and is used to drive the ring body 41 to slide up and down. The upper end of the driving rod 43 is connected to a driving block 44, and a limiting ring 45 is connected to the side wall of the driving rod 43. A first spring 46 is connected between the limiting ring 45 and the upper end surface of the tube body 3. The setting of the installation component 4 can separate the retaining ring 11 from the sleeve 42, so that the retaining ring 11 enters the retaining ring groove on the rotating shaft 10.

[0025] A supporting assembly 6 for supporting the retaining spring 11 is installed on the base plate 1, and the supporting assembly 6 includes a mounting plate 61, a slider 62 and a support block 63. The mounting plate 61 is installed on the base plate 1, and the sliders 62 are slidably connected in the sliding grooves provided on both sides of the mounting plate 61. The support blocks 63 are connected to the sliders 62. The second spring 64 for driving the two sliders 62 to move closer to each other is provided in the sliding groove of the mounting plate 61. The structural shape of the support block 63 is set to a circular arc sheet structure. The support block 63 can slide toward both sides of the mounting plate 61 during the downward pressing of the expansion block 73, so as to facilitate the auxiliary expansion assembly 7 to expand the retaining spring 11.

[0026] The middle part of the supporting assembly 6 is provided with an expansion assembly 7 for expanding the retaining spring 11. The expansion assembly 7 includes a mounting column 71, a telescopic column 72 and an expansion block 73. The mounting column 71 is connected to the middle position of the supporting assembly 6, and the telescopic column 72 is movably nested and connected in the mounting column 71. The expansion block 73 is connected to the upper end of the telescopic column 72. The expansion block 73 is set to an inverted conical structure. A third spring for driving the telescopic column 72 to move upward is provided in the mounting column 71. The central axis of the expansion block 73 coincides with the central axis of the sleeve 42. The expansion block 73 with a conical structure squeezes the inner ring of the retaining spring 11 to expand the retaining spring 11, and makes the retaining spring 11 slide on the conical surface of the expansion block 73 to the sleeve 42, so that the mounting assembly 4 can install the retaining spring 11.

[0027] A thread is provided on the outer wall of the tube body 3, and a stop block 8 is threadedly connected to the outer wall of the tube body 3. The stop block 8 can fit on the surface of the shaft frame 9 to control the position of the tube body 3 entering the deep hole, thereby facilitating the installation of the retaining spring 11 in alignment with the retaining spring groove, and by adjusting the position of the stop block 8, it can be suitable for the installation of retaining springs 11 of workpieces of different sizes.

[0028] The working process of the present invention is as follows:

[0029] like Figure 5 and 6 As shown, when it is necessary to install this type of retaining spring 11 on the rotating shaft 10 located in the deep hole of the shaft frame 9, first place the opening of the retaining spring 11 through the telescopic column 72 and place it on the support block 63, press the driving block 44 downward, so that the driving block 44 drives the sleeve 42 to move downward through the driving rod 43, and the sleeve 42 fits into the expansion block 73 and presses it downward, so that the expansion block 73 expands the retaining spring 11. In the process of expanding the retaining spring 11, the expansion block 73 squeezes the support block 63, so that the support blocks 63 on both sides of the mounting plate 61 move away from each other, and the support block 63 always maintains support for the retaining spring 11, and the retaining spring 11 slides onto the sleeve 42 on the conical surface of the expansion block 73.

[0030] The tube body 3 is removed from the support frame 2 and inserted into the hole of the shaft frame 9 so that the sleeve 42 is sleeved on the rotating shaft 10. When the stop block 8 is in contact with the lower end surface of the shaft frame 9, the retaining spring 11 reaches the retaining spring groove position on the rotating shaft 10, and the driving block 44 is pulled to drive the sleeve 42 to slide upward relative to the tube body 3. When the sleeve 42 is completely retracted into the tube body 3, the retaining spring 11 is disengaged from the sleeve 42 and engaged with the retaining spring groove on the rotating shaft 10, thereby realizing quick and accurate installation of the retaining spring 11. When it is necessary to install the retaining spring 11 at different depths, the position of the retaining spring 11 can be adjusted by rotating the stop block 8 to control the position of the tube body 3 entering the deep hole, so that the retaining spring 11 is aligned with the retaining spring groove to achieve accurate installation of the retaining spring 11.
