Detailed Description
For better understanding of the present invention, the technical solutions and effects of the present invention will be described in detail by the following embodiments with reference to the accompanying drawings.
An assembly method for solving deformation failure of a retainer ring after assembly specifically comprises the following steps:
the method comprises the following steps: and preparing parts and a clamping ring anti-deformation assembly tool for the plug assembly to be assembled completely.
The collar anti-deformation assembling tool comprises a cone base 5 and a handle 4, as shown in fig. 4, the cone base 5 is a rotary cone, and the outer diameter of the large-diameter end is equal to the outer diameter of the plug 1; the middle part of the large-diameter end of the cone base 5 is provided with a first blind hole 51 along the axial direction for accommodating the bulge at the end part of the plug 1, so that interference in the rotating and matching process is prevented, and the positioning function is achieved.
As shown in fig. 3, the handle 4 is a rotating cylinder, and a second blind hole 41 is axially formed in the middle of one end of the handle and is used for being sleeved outside the cone base 5 to assemble the collar 3 in the annular groove of the plug 1. The aperture of the blind hole of the handle 4 is larger than the major diameter of the cone base 5 and smaller than the outer diameter of the clamping ring 3, and meanwhile, the outer diameter of the handle 4 is larger than the outer diameter of the clamping ring 3; the depth of the blind hole of the handle 4 is larger than the sum of the height of the cone base 5 and the distance from the end face of the plug 1 to the annular groove.
Step two: the plug 1 is arranged in the nut 2, and the cone base 5 of the clamping ring anti-deformation assembly tool is placed on the plug 1, so that the major diameter of the cone base 5 coincides with the outer diameter of the plug 1.
Step three: the collar 3 is sleeved on the cone base 5.
Step four: the handle 4 of the clamping ring anti-deformation assembly tool is sleeved outside the cone base 5 through the second blind hole 41, so that the handle 4 pushes the clamping ring 3 to axially move along the outer conical surface of the cone base 5 until the clamping ring 3 is pressed into the annular groove of the plug 1, and the assembly is completed.
The method breaks through the assembly of the clamping ring 3 from two defense lines, namely, the clamping ring 3 is uniformly deformed in the transferring and assembling process, and the clamping ring 3 is minimally deformed in the assembling process. 1. Uniform deformation: the clamping ring 3 is placed on the base cone, and is gradually deformed along the cone conical surface and gradually slides into the groove of the plug 1, so that the purpose that the clamping ring 3 is uniformly deformed in the assembling process is achieved.
Step five: the handle 4 and the cone base 5 are removed.
A plurality of collars 3 are assembled and compared simultaneously using conventional methods and methods provided by the present invention, with the results shown in table 1 below:
TABLE 1 data comparison of conventional methods and assembly methods provided herein
From the above data, the post-assembly deformation amount of the assembly method provided by the present application is on average 0.15mm smaller than that of the conventional assembly method. Therefore, the assembling method provided by the application has great advantages.
