Problems solved by technology

However, for Tuojiang jade with complex shape, irregularity, uniqueness, and low surface roughness, the position of the surface to be processed varies greatly, and it is impossible to use general-purpose fixtures such as chucks, briquetting blocks, and vices for positioning
First of all, the clamping of Tuojiang jade is difficult, and the reliability of clamping is difficult to guarantee, especially in batch processing, there are problems such as low part replacement efficiency and high clamping labor intensity; secondly, the spindle has a relatively high speed during finishing machining. It is more than 20000r / s, it is very easy to generate vibration and cause the movement and rotation of the rough stone, which is easy to cause processing accidents

Embodiment 1

[0016] Embodiment 1: see figure 1 , a fast clamping fixture suitable for processing natural raw jade with complex shapes, including a fixture base 1 and a clamping mechanism 2 . The fixture base 1 is composed of a base plate 11 and four side plates 12 arranged on the base plate and forming a rectangle, forming a stable frame structure. Wherein, at least any two adjacent side plates are provided with a clamping mechanism 2, and the position of the clamping mechanism 2 is adjusted and fixed through the threaded hole 3 located on the side plate; The other side plates not equipped with the clamping mechanism 2 and the bottom plate 11 jointly restrict the movement of the clamped part in X, Y and Z directions.

[0017] One, two or three clamping mechanisms 2 are arranged on the bottom plate 11 .

[0018] The clamping mechanism 2 is composed of a universal support 21 and a screw 22. The universal support 21 includes a spherical mandrel and a spherical sleeve. One end of the spheric...

Embodiment 2

[0020] Embodiment 2: (figure omitted), a quick clamping fixture suitable for processing natural raw jade with complex shapes, including a fixture base and a clamping mechanism. The fixture base is composed of a bottom plate and three side plates arranged on the bottom plate and forming a triangle, forming a stable frame structure. Wherein, any side plate is provided with a clamping mechanism, and the clamping mechanism is composed of a universal support and a screw rod, and the screw rod passes through the threaded hole and is perpendicular to the side plate, and the position is adjusted by the and fixed; the clamping head of the clamping mechanism 2 together with the other side plates and the bottom plate 11 not equipped with the clamping mechanism limit the movement of the clamped piece in the X, Y and Z directions.

Embodiment 3

[0021] Embodiment 3: (figures omitted), a quick clamping fixture suitable for complex-shaped natural raw jade processing, including a fixture body and a telescopic mechanism, the fixture is a polygonal hollow structure, and the upper part is an open structure to form The storage opening for placing the workpiece to be clamped is provided with a telescopic mechanism on at least two sides of the fixture body that are perpendicular to the plane where the storage opening is located and adjacent to each other. The working direction of the telescopic mechanism is perpendicular to The surface where it is located points to the inside of the fixture body. A universal support is connected to the inner end of the telescopic mechanism. The telescopic mechanism pushes the universal support to move along the working direction of the telescopic mechanism so that the universal support is the same as the universal support The opposite surface and the surface far away from the storage opening jo...

Abstract

The invention discloses a quick clamping fixture suitable for machining of original natural jade with a complicated shape. The quick clamping fixture comprises a fixture base and clamping mechanisms, wherein the fixture base consists of a base plate and multiple side plates which are arranged on the base plate and form a polygon in an enclosing manner, thus forming a stable framework structure; the clamping mechanisms are arranged on at least one or every two adjacent side plates; the clamping mechanisms are subjected to position adjustment and fixing through thread holes formed in the side plates; chucks of the clamping mechanisms, other side plates without the clamping mechanisms and the base plate jointly limit the movement of a clamped piece in the X, Y and Z directions. The quick clamping fixture effectively solves the problems that the original natural jade is difficult to clamp during machining, a surface to be machined is difficult to locate, the clamping stability is hard to guarantee, the part replacement efficiency is low, the clamping labor intensity is high and the like.

Description

technical field [0001] The invention relates to a fixture, in particular to a quick clamping fixture suitable for processing natural raw jade with complex shapes. It belongs to the technical field of mechanical manufacturing. Background technique [0002] Natural raw jade with complex shapes has high aesthetic value and practical value, so it is often processed into ornaments. However, natural raw jade with complex shapes is often formed naturally in nature. The main chemical composition is mainly silicon dioxide, followed by a small amount of iron oxide and trace amounts of manganese, copper, etc., which determines that the shape of natural raw jade with complex shapes is irregular and the material is irregular The characteristics of uniformity and high hardness; secondly, the processing of natural raw jade with complex shapes also has the characteristics of individualization and small batches. These characteristics and characteristics of natural raw jade make it difficul...
