Embodiment Construction

[0014] Such as figure 1 and 2 As shown, the high-precision center positioning tool of the present invention includes a positioning mandrel 1 and a taper sleeve mandrel 2. The positioning mandrel 1 is coaxially embedded in the taper sleeve mandrel 2 and is positioned and matched to ensure the repeatability of the tooling. Positioning accuracy, twelve positioning steel balls 4 are arranged at the same cross-section and equal angles between the tapered sleeve mandrel 2 and the positioning mandrel 1, and the positioning steel balls 4 and the tapered sleeve mandrel 2 adopt a gapless fit, which can ensure The positioning steel ball 4 is flexible, and an O-ring 3 is provided between the taper sleeve mandrel 2 and the positioning mandrel 1 to effectively prevent the entry of iron filings and ensure the flexible rotation of the positioning steel ball 4 .

Abstract

The invention discloses a precision centralized positioning tool comprising a positioning mandrel and a taper sleeve mandrel. The positioning mandrel is coaxially embedded in the taper sleeve mandrel and is positioned in a matched manner. A plurality of positioning steel balls are arranged between the taper sleeve mandrel and the positioning mandrel on same cross section with same angles, and are in gap-free fit with the taper sleeve shaft. The precision centralized positioning tool has the advantages that the positioning steel balls and the taper sleeve mandrel are in gap-free fit so that the positioning steel balls are guaranteed moving flexibly; the taper sleeve mandrel and the positioning mandrel are positioned in the matched manner of taper positioning and end face positioning, and repeated positioning precision of the tooling is guaranteed; an O-shaped ring can prevent scrap iron from entering, and the positioning steel balls are guaranteed rotating flexibly.

Description

technical field [0001] The invention relates to a positioning tool, in particular to a high-precision center positioning tool. Background technique [0002] The large end face of the original processed A4V series housing adopts optical axis positioning, the repeat positioning accuracy of optical axis positioning is relatively low (between 0.03-0.05), and it is difficult to disassemble and assemble, resulting in the coaxiality of the processed housing bearing and the mounting hole of the rear cover The degree of deviation is relatively large (above 0.05). [0003] Therefore, there is an urgent need for an improved technology to solve this problem in the prior art. Contents of the invention [0004] The invention provides a high-precision center positioning tool. [0005] The technical scheme adopted in the present invention is: [0006] High-precision center positioning tooling, including a positioning mandrel and a taper sleeve mandrel, the positioning mandrel is coaxia...
