Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, all embodiments that those of ordinary skill in the art obtain under the prerequisite not paying creative work all belong to protection domain of the present utility model.
The utility model embodiment provides a kind of snap ring assembly tooling, as shown in Figure 2, comprising: guide part 6 and press-fit portion 7, and wherein, guide part 6 is sleeved on the outer surface of axle 5, and press-fit portion 7 is supported on the end face of guide part 6; The size of the first end of guide part 6 is less than the internal diameter under snap ring 1 free state, and the size of the second end of guide part 6 is greater than the internal diameter under snap ring 1 free state; Press-fit portion 7 is cylindrical-shaped structure, and the internal diameter of press-fit portion 7 be greater than internal diameter under snap ring 1 free state, be less than snap ring 1 free state under external diameter, the external diameter of press-fit portion 7 is greater than the size of the second end of guide part 6.This snap ring assembly tooling; in snap ring 1 assembling process; snap ring 1 can be made to be sleeved on guide part 6 by the squeezing action of press-fit portion 7 and finally be arranged on annular groove 4 position; under the guiding and protective effect of guide part 6; can ensure that axle 5 outer surface is not damaged; and make snap ring 1 not produce distortion, damage, the installation of snap ring 1 can be carried out quickly and easily.
As shown in Figure 3, guide part 6 comprises: the installation portion 8 of integrative-structure and protection portion 9, and wherein, installation portion 8 is cone-shaped structure, and protection portion 9 is cylindrical-shaped structure; The first end of guide part 6 is positioned on installation portion 8, and the second end of guide part 6 is positioned in protection portion 9.By installation portion 8 is set to cone structure, snap ring 1 is in installation process, first be sleeved on one end that the conical surface is less, then under the squeezing action of press-fit portion 7, the direction (in the direction of the arrow) larger to the conical surface is mobile, can ensure that snap ring 1 is progressively supportted greatly, ensure that its deformation quantity is controlled, thus prevent snap ring 1 from producing permanent deformation.Those skilled in the art easily arrange the internal diameter of protection portion 9 according to the external diameter of axle 5, the internal diameter of protection portion 9 is set to the external diameter slightly larger than axle 5, thus protection portion 9 can be sleeved on axle 5, and can not strut excessive by snap ring 1.Kept apart between axle 5 and snap ring 1 by protection portion 9, can prevent shaft part outer surface coarse in installation process from scratching snap ring 1 on the one hand, can also prevent shaft part outer surface from producing flanging burr on the other hand.Wherein, the tapering of cone-shaped structure can be arranged according to the external diameter equidimension of the length of installation portion 8 and axle 5; preferably be set to 1 degree; can ensure can comparatively gently be stretched in snap ring 1 installation process; and can open equal with the external diameter of protection portion 9 at installation portion 8 with the internal diameter of the link position snap ring 1 of protection portion 9, thus can overlap easily and install in protection portion 9.
In the utility model embodiment, preferably the length of above-mentioned installation portion 8 is set to the length equaling the first shaft part 2, and the length of protection portion 9 is set to the length equaling the second shaft part 3.Because the first shaft part 2 of axle 5 is equal with the length of the second shaft part 3, therefore, the length of installation portion 8 can be set to the length equaling protection portion 9, thus make on the shaft shoulder of the connecting portion of installation portion 8 and protection portion 9 in the middle part of the first shaft part 2 and the second shaft part 3.
As shown in Figure 4, press-fit portion 7 is provided with two handles 10, thus snap ring 1 can be extruded conveniently by manual operation and move to annular groove 4 direction.Specifically can by two handles 10 symmetry arrangement in the both sides of press-fit portion 7, so that manual hold.
In order to ensure that guide part 6 and press-fit portion 7 have enough intensity, Material selec-tion need adopt the such as good material of steel equal strength to make, because guide part is thin-wall part, therefore, the better high-carbon-chromium bearing steel of preferred employing rigidity (GCr15) is made, and press-fit portion 7 then can adopt No. 45 steel to make.
As shown in Figure 5, above-mentioned snap ring 1 is tool circular ring jaggy.In order to install needs, those skilled in the art easily know that snap ring 1 needs to adopt and has certain elasticity and the enough material of intensity is made, thus elastic deformation can be produced within the specific limits when stressed, and after cancelling External Force Acting, can restore to the original state, after being installed into annular groove 4, positioning action can be played.
The snap ring assembly tooling that the utility model embodiment provides, is set to be less than the internal diameter under snap ring free state by the size of the first end of guide part, the size of the second end of guide part is set to be greater than the internal diameter under snap ring free state; The internal diameter of press-fit portion is set to be greater than the internal diameter under snap ring free state, the external diameter be less than under snap ring free state; the external diameter of press-fit portion is set to the size of the second end being greater than guide part; thus in snap ring assembling process; snap ring can be made to be sleeved on guide part by the squeezing action of press-fit portion and finally be arranged on annular groove position; under the guiding and protective effect of guide part; can ensure that axle outer surface is not damaged; and make snap ring not produce distortion, damage, the installation of snap ring can be carried out quickly and easily.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
