Metal material cake clamp and personalized machining center

Abstract

The invention discloses a metal material cake clamp which comprises a frame mounting part and a clamping part, wherein the clamping part is perpendicular to the frame mounting part. The clamping part comprises an annular lid and an annular tray which are detachably connected, and a metal material cake clamping cavity is formed between the annular lid and the annular tray. The mounting part comprises a plug and a protective cover; the protective cover is provided with a round end face and is fixedly connected with the annular tray through the end face; and the plug is located in the protective cover. The metal material cake clamp can stably clamp a circular-cake-shaped metal material cake so that a personalized machining center can directly machine the metal material cake into a plurality of personalized products of different sizes at a time, meanwhile, a piece taking manipulator which is essential for an existing machining center can be omitted, the production efficiency is improved, and the equipment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of machine tool parts, in particular to a metal cake clamp and a personalized machining center. Background technique [0002] In the field of dental implant technology, a large number of personalized products, such as implant guides and implants, need to be applied. Most of these personalized products are realized by 3D printing technology or casting technology, but they have the following disadvantages: ①. Due to the combination of biological activity, the bottom of the abutment needs to be made of cobalt chromium alloy, but 3D printing technology cannot use cobalt chromium Alloys are used as processing materials, so the metals used in the product are not exactly the same, and the melting temperature is also different, so that they are not completely fused together, but only mechanically combined; Pulp, if there are two different metal restorations in contact in the oral cavity, a "potential difference" wi...

Most of these personalized products are realized by 3D printing technology or casting technology, but they have the following disadvantages: ①. Due to the combination of biological activity, the bottom of the abutment needs to be made of cobalt chromium alloy, but 3D printing technology cannot use cobalt chromium Alloys are used as processing materials, so the metals used in the product are not exactly the same, and the melting temperature is also different, so that they are not completely fused together, but only mechanically combined; Pulp, if there are two different metal restorations in contact in the oral cavity, a "potential difference" will be generated through saliva, and the micro-current will stimulate the dental pulp to a certain extent, which may have certain effects on sensitive patients; ③, after embedding → High temperature grilling (expansion) → melting and casting of the metal → cooling (shrinkage) → removal of the embedding powder → the oxide layer produced → sandblasting → grinding and polishing, many processes will be interfered by human factors, Resulting in greater impact on strength and precision

Moreover, the specificity of the fixture is very strong, metal bars of different diameters must use the corresponding type of fixture, so it needs to be disassembled and replaced frequently

These complex processing and production processes have greatly slowed down the production of personalized products
