Description
Technical Field
The invention belongs to the technical field of mechanical assembly, and particularly relates to a method for quickly installing a deep lining.
Background
The depth of a bushing mounting hole of an aluminum alloy product is 36mm, and as shown in figure 1, the mounting fit is phi 16s6/H7 interference fit. Quick installation is required and the coaxiality of the inner hole after the bushing is installed is not more than phi 0.03. The lining material is 1Cr17Ni2, and the surface treatment is passivation.
Currently, for the installation of the bush, the following two methods are generally employed.
The first method comprises the following steps: the inner hole of the bush is not processed in a part state, and after the inner hole of the product main body is filled with the inner hole, the phi 12H9 hole is integrally processed.
The second method comprises the following steps: the perforated liner is directly installed into the inner bore of the product body. A
However, in the first method, the bush may fall off during the processing of the inner bore of the bush, the inner bore of the bush after processing cannot be subjected to surface treatment, and the rust phenomenon is generated during the subsequent use. With the second method, during installation of the bushing into the inner bore of the product body, the bushing inner bore is easily deformed and has poor coaxiality.
Disclosure of Invention

Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
The embodiment provides a method for quickly mounting a deep bushing, which uses a bushing mounting positioning shaft shown in fig. 2, wherein the material is 30CrMnSiA, and the hardness value is 33 HRC-38 HRC. The bushing mounting and positioning shaft comprises a limiting section, a supporting section and a guiding section, wherein the outer diameter of the limiting section is reduced in sequence. Wherein the spacing section has a phi 20 excircle larger than the inner hole of the product main body, and the supporting section hasThe outer circle and the guide section are provided withThe outer circle of the circular ring is provided with a circular hole,andthe size and the coaxiality are required to be ensured by the machining of the cylindrical grinding machine. Wherein the guide section isThe outer circle is in small clearance fit with the inner hole phi 12H9 of the bushing,the excircle and the inner hole phi 16H7 of the main body of the product are in small clearance fit, thereby not only ensuring the coaxiality requirement after the bushing is installed, but also ensuring the bushingThe sleeve mounting positioning shaft can be smoothly inserted and pulled out in the mounting process.
The method for quickly installing the deep bushing comprises the steps of firstly inserting the bushing installation positioning shaft 2 into the inner hole of the main body of the product 1 to ensure that the supporting section of the positioning shaft 2The excircle penetrates through an inner hole of a phi 16H7 main body of the product 1 and is limited by a limiting section; then the guide section of the positioning shaft 2 is positionedThe excircle passes through an inner hole phi 12H9 of the bushing 3 to complete the guiding; then, the bush 3 is pressed into the inner hole of the main body of the product 1 by using the sleeve 4, and after the bush 3 is pressed, the coaxiality of the inner hole of the bush is not more than phi 0.03.
After the assembly is completed, the guide section phi 12 excircle part of the bushing mounting and positioning shaft penetrates into the bushing inner hole, and if the bushing mounting and positioning shaft can smoothly penetrate without clamping stagnation, the coaxiality of the bushing inner hole meets the use requirement.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
