[0002] Mechanical parts, also known as mechanical elements, are the basic components of machinery and are inseparable individual parts that make up machinery and machines. Mechanical parts are not only a discipline for studying and designing basic mechanical parts in various equipment, but also a general term for parts and components. The specific content of mechanical parts as a discipline includes: 1. Connection of parts (components). Such as threaded connection, wedge connection, pin connection, key connection, spline connection, interference fit connection, elastic ring connection, riveting, welding and adhesive connection, etc.
[0003] The existing cylindrical mechanical parts cannot be disassembled after being welded and fixed, and the welding deformation is large, which affects the size of other parts. Some of them are fixed by top screws and screws, which takes up a large space and leaves no space for arrangement when the design structure is compact. For this reason, we propose a nested installation structure for cylindrical mechanical parts. Utility Model Content

[0006] Preferably, the first limiting groove includes three first anti-rotation grooves, which are arranged inside the first top component, and the second limiting groove includes three second anti-rotation grooves, which are arranged inside the fourth cylinder, which is conducive to the misalignment of the plane position so that it cannot move axially.
[0007] Preferably, the first anti-rotation groove includes three first milling planes, which are opened on the outside of the first cylinder, and the second anti-rotation groove includes three second milling planes, which are opened on the outside of the fifth cylinder, which is conducive to the staggered position of the planes so that they cannot move axially.
[0008] Preferably, a first pin hole is opened inside the first milling plane, and a second pin hole is opened inside the second milling plane. The two parts are rotated until the inner and outer pins are aligned, and then the pins are inserted to position them so that the two parts do not rotate.
[0009] The utility model provides a mutually nested installation structure of cylindrical mechanical parts, which has the following beneficial effects:
[0010] 1. The cylindrical mechanical parts are nested in each other and installed in a structure. The first milling plane, the second milling plane, the first anti-rotation groove and the second anti-rotation groove are designed through the first top component, the first cylinder, the second cylinder, the third cylinder and the fourth cylinder, the outer ring, the second top component and the fifth cylinder. After being installed in place and rotated, the first milling planes, the second milling planes, the first anti-rotation groove and the second anti-rotation groove of the two parts are staggered, so that they will not move axially anymore. At the same time, the circumferential direction is positioned by pins and finally fixed, so that there is no need to use top screws and screws for fixing, which greatly reduces the space occupied and avoids the influence on the size of other parts.
[0011] 2. The cylindrical mechanical parts are nested in each other and installed in a structure with a second pin hole and a first pin hole. When disassembling, the pin can be removed and the two parts can be rotated to align the two milled parts. At this time, the parts can be disassembled axially, so that the mechanical parts can be easily disassembled, thereby greatly improving the convenience of use, and there is no need to occupy space by welding.
