Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to an intelligent numerical control machine tool clamping mechanism. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary cone angles, complex rotary inner and outer curved surfaces, and cylindrical and conical threads. It can also perform grooving, drilling, reaming, reaming and boring. Users of CNC lathes need to use workpiece clamping mechanisms.

[0003] Among them, the "A workpiece clamping mechanism for CNC machine tools" disclosed in the application number "CN220881499U" has solved the various disadvantages of the current workpiece clamping mechanism that requires manual rotation of the turntable to clamp the workpiece, which affects the work efficiency, and the clamping method through the linkage mechanism cannot be fixed when one of the components is damaged, and the maintenance cost is high. After further searching, it was found that the "A workpiece clamping mechanism for CNC machine tools" disclosed in the application number "CN219665750U" has effectively solved the problem that the clamping head used for clamping is usually fixed and cannot be replaced through a specific technical structure setting, thereby making the workpiece that the clamping head can clamp The types are limited, or when using the clamping head to clamp some different types of workpieces, the workpiece cannot be clamped stably, which can easily lead to work errors, affect the quality of workpiece processing, and reduce the efficiency of workpiece processing. Technical disadvantages, but in actual use, CNC machine tool clamping mechanisms with similar structures still have many defects, such as: when the existing CNC machine tool workpiece clamping mechanism limits the workpiece, it is usually to fix the position of the tubular or rod-shaped workpiece by rotating the bolts of the clamping mechanism, which will greatly affect the processing efficiency of the workpiece and the efficiency is low during the clamping process. Therefore, it is necessary to design an intelligent CNC machine tool clamping mechanism to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0019] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0020] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0021] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0022] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0023] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first member, component, region, layer, or portion referred to may also be referred to as the second member, component, region, layer, or portion.

[0024] For ease of description, spatial relative terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the drawings. Such spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element would then be located "below" or "lower" relative to the other element.

[0025] Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0026] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "include", "comprise" and "have" list the stated features, quantities, operations, components, elements and / or their combinations that exist, but do not exclude the existence or addition of one or more other features, quantities, operations, components, elements and / or their combinations.

[0027] Variations in the shapes shown in the drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include variations in shapes that occur during manufacturing.

[0028] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.
