Embodiment Construction

[0035] The installation structure is positioned by the circumscribed cylindrical surface of non-circular cross-section components. The schematic diagram of the cross-sectional structure is as follows: figure 1 As shown, it includes a mounting seat 1 and a non-circular section element 2, and a connecting sleeve 3 is provided. The connecting sleeve 3 is a cylindrical structure. The outer diameter of the connecting sleeve 3 is the same as the diameter of the circumscribed cylindrical surface of the non-circular section element 2. The connecting sleeve 3 One end of the groove 4 is arranged in the axial direction, the section of the groove 4 contains the section of the non-circular section element 2, the length of the groove 4 along the axial direction of the connecting sleeve 3 is less than the length of the non-circular section element 2, and the length of the connecting sleeve 3 The length is greater than the length of the groove 4, and the shape and size of the groove bottom of ...

Abstract

A mounting structure positioned by the aid of an external cylindrical surface of an element with a non-circular section is provided with a connecting sleeve. The connecting sleeve is a cylindrical structure, the outer diameter of the connecting sleeve is identical to the diameter of the external cylindrical surface of the element with the non-circular section, a groove is arranged at one end of the connecting sleeve, the section of the groove contains the section of the element with the non-circular section, the length of the groove is smaller than that of the element with the non-circular section, the length of the connecting sleeve is larger than that of the groove, a mounting seat is provided with a mounting hole, the diameter of the mounting hole matches with the outer diameter of the connecting sleeve, and one end of the connecting sleeve is fixedly connected with the mounting hole in a threaded manner. By the aid of the mounting structure positioned by the aid of the cylindrical surface of the element with the non-circular section, the element with the non-circular section is mounted into the groove and placed into the mounting hole to be mounted, machining of a difficultly machined hole with a non-circular section can be omitted, production cost is lowered, and the mounting structure is convenient in installation and machining, accurate in positioning, speedy in installation, convenient in sealing and quite remarkable in effect.

Description

technical field [0001] The invention relates to an installation structure, in particular to an installation structure which uses a non-circular cross-section element to circumscribe a cylindrical surface for positioning. Background technique [0002] The mosaic installation of non-circular cross-section components usually adopts the method of machining non-circular cross-section holes on the mounting base that adapt to the shape of non-circular cross-section components, and then inserting non-circular cross-section components into the holes, but the hole processing of non-circular cross-section Difficulty and high cost. This problem is more prominent when the cross-sectional size of non-circular cross-section components is small. This installation method will also increase the complexity of the structure and shape of the mounting seat, and increase the axial positioning and Difficulty in radial positioning, and greatly increases the difficulty of installation and disassembly...
