Description

[Technical Field]

[0001] This utility model relates to the technical field of component clamping and positioning devices, and in particular to a low-deviation clamping and positioning device for mobile phone ring CNC machining parts with reasonable structural design and outstanding application effect. [Background Technology]

[0002] With the increasing popularity and technological advancements of mobile phones and other electronic products, the issues involved in their production processes have been gradually improved. In actual manufacturing, ring-shaped parts are frequently used in mobile phone accessories. These ring-shaped parts are very delicate and require chucks for fixing during processing. Commercially available chucks contain gear transmission and threaded structures, allowing the expansion or contraction of each jaw to be controlled synchronously by a wrench, thereby tensioning or clamping the ring-shaped parts. However, chucks with this structure require sufficient internal space to accommodate the transmission structure, resulting in a larger size. They are generally suitable for fixing larger workpieces but not for clamping small precision parts. Furthermore, existing clamping devices suffer from problems such as easy initial positioning errors and the inability to effectively adjust and strengthen the clamping force, which affect the entire subsequent processing.

[0003] For example, the utility model patent with application number CN202121645259.3 and patent title "A Clamping Fixture for Circular CNC Machining Parts for Mobile Phones" specifically discloses a clamping fixture for circular CNC machining parts for mobile phones, relating to the field of clamping fixtures. Addressing the problem of inconvenient fixing of existing circular mobile phone parts, the following solution is proposed: It includes a base, with a disc at the top. The circumferential sidewall of the disc has a sliding groove and an annular groove. A slider is slidably connected within the sliding groove, and a steel wire rope is wound within the annular groove. Two sets of supports are provided on the circumferential sidewall of the disc. A first hollow groove and a second hollow groove are respectively formed on adjacent sides of the base, both penetrating the base and connected to each other. The sliding groove is inverted T-shaped and arranged radially along the disc, forming a circular array about the disc. This utility model has a novel structure, and the device effectively solves the problem of inconvenient fixing of existing circular mobile phone parts.

[0004] The aforementioned existing technical solutions suffer from the problem that relying solely on sliders for positioning can easily lead to excessive positional deviations, thus preventing effective clamping. [Utility Model Content]
