Description

Technical Field

[0001] The utility model relates to the technical field of metallographic cutting machines, in particular to a clamp auxiliary device for a metallographic cutting machine. Background Art

[0002] Metallographic cutting machine is suitable for cutting metallographic specimens of various metal materials in order to observe the metallographic structure of the materials.

[0003] When using the cutting machine, the operator needs to use a clamp to fix the cutting piece to prevent it from shifting or shaking and affecting the cutting accuracy. However, the existing metallographic cutting machine generally has a pair of clamps or two pairs of clamps. Only one pair of clamps is not conducive to stable cutting. The cutting machine with two pairs of clamps is very inconvenient to clamp cutting pieces of different sizes because the distance between the clamps is fixed. It is difficult to adjust. In addition, there is only one V-shaped groove on the side wall of the clamp. One side of the plate cutting piece or the rod and wire cutting piece is placed in the V-shaped groove, and the other side is fixed by a clamping device. For rod and wire specimens with smaller diameters, it is difficult to clamp the specimen with the clamp, so that the accuracy requirements cannot be met during vertical cutting. For samples that need to be analyzed for surface defects, since the clamp cannot be clamped to the defects on the surface of the sample during the cutting process, it is necessary to clamp the two sides of the cutting piece with a clamp to avoid clamping to the defective part, otherwise it will affect the judgment. If the cutting piece is a thin plate or a plate with too large size, the clamp will not be clamped during the vertical cutting process, resulting in the phenomenon of the cutting piece being cut obliquely or falling off.

[0004] In view of this, it is necessary to study and improve the deficiencies of the existing technology and provide a metallographic cutting machine clamp auxiliary device with the advantages of easy loading and unloading, flexible and convenient operation, and a wide range of applications, so as to make it more practical and greatly improve the test efficiency.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
