Location mechanism for curved-surface circular ring

Abstract

The invention discloses a location mechanism for a curved-surface circular ring. The location mechanism for the curved-surface circular ring comprises a location shaft assembly, a calibration elementand a fixing element, wherein the curved-surface circular ring is arranged on the location shaft assembly in a sleeved manner, a location structure used for carrying out radial location on the inner wall of the curved-surface circular ring is arranged in the location shaft assembly, and the calibration element is installed on the location shaft assembly, and used for carrying out circumferential and axial limit on the curved-surface circular ring; and the fixing element is installed on the location shaft assembly, and used for applying a pressure onto the calibration element. The location mechanism for the curved-surface circular ring is simple in structure, easy to machine, convenient to operate, high in universality, and capable of carrying out locating on a series of quasi-curved-surface circular ring parts, so that the equipment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of product positioning, in particular to a curved ring positioning mechanism. Background technique [0002] With the development of smart wearable electronic products, more and more product shapes are developing towards irregular surfaces to adapt to the shapes of human ears, eyes, fingers and other parts, making the human wearing experience more comfortable. In the process of assembling this type of product, a mechanism or tooling for positioning irregular curved surface ring parts inevitably appears. Common irregular surface ring structures such as figure 1 As shown, the curved ring 1 includes an annular body 11, the inner cavity of which is a curved surface of the opposite sex, the two ends of the annular body 11 are respectively provided with radially outwardly extending edge portions 12, and a U-shaped plate is arranged between the two edge portions 12 13. The two vertical plate portions 131 of the U-...

Problems solved by technology

However, the above-mentioned positioning mechanism (profiling positioning) has the following deficiencies and disadvantages: ①Profiling surface is difficult to process, and the cost is high; ②Profiling positioning uses the part profiling surface as a positioning reference, and the positioning deviation is large. The ring positioning shakes; ③The profiling positioning can only locate one type of curved ring parts, which has poor versatility. When the height of the corner or the axial span of the two extensions changes slightly), it is necessary to perform profiling positioning one by one, which greatly increases the number of positioning mechanisms used and increases the cost of equipment.
