[0029] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0032] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0033] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0034] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0035] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0036] Figure 1 It is a schematic diagram of the overall structure of a tool wear detection device for a shield machine according to an embodiment of the present disclosure.

[0039] like Figure 2 As shown, in the present disclosure, the rotating lifting mechanism 2 includes a driving motor 21, an outer sleeve shaft 22, a longitudinal slide groove 23, a threaded rod 24, a guide slide column 25 and a placement plate 26, wherein the driving motor 21 is fixedly arranged on the inner side of the workbench 1, the outer sleeve shaft 22 is transmission-connected to the top of the driving motor 21, the longitudinal slide groove 23 is opened on the side of the outer sleeve shaft 22, the threaded rod 24 is slidably arranged on the inner side of the outer sleeve shaft 22 along the vertical direction, the threaded rod 24 penetrates the inner wall of the workbench 1 and extends to the top of the workbench 1 and is threadedly connected to the workbench 1, the guide slide column 25 is slidably arranged on the inner side of the longitudinal slide groove 23 and is fixedly connected to the threaded rod 24, and the placement plate 26 is fixedly arranged on the top of the threaded rod 24.

[0040] Therefore, after the tool to be tested is placed on the top of the placement plate 26 and fixed, the drive motor 21 is energized. After the drive motor 21 is energized, it drives the outer sleeve shaft 22 to rotate. When the outer sleeve shaft 22 rotates, it drives the threaded rod 24 to rotate through the longitudinal slide groove 23 and the guide slide column 25. When the threaded rod 24 rotates, it drives the tool to be tested to rotate through the placement plate 26. At the same time, since the threaded rod 24 is threadedly connected to the workbench 1, the tool to be tested is driven to rise through the placement plate 26 during the rotation of the threaded rod 24, thereby enabling the tool to be tested to realize a rotation and rising operation to avoid the existence of a detection blind spot.

[0041] Figure 3 It is a schematic structural diagram of a wear detection mechanism 3 and a clamping and fixing mechanism 4 of a tool wear detection device for a shield machine according to an embodiment of the present disclosure.

[0043] Therefore, during the rotation and rising process of the tool to be tested, the detection camera 32 can photograph the tool to be tested, thereby completing the wear detection operation. The annular fill light 33 is provided for performing fill light operation during the shooting process. It should also be noted that the detection camera 32 belongs to a solution that has been disclosed in the prior art and is not a necessary technical feature of the present application. Therefore, the present application does not elaborate on its specific structure and principle.

[0044] like Figure 3 As shown, in the present disclosure, the clamping and fixing mechanism 4 includes a fixed clamping plate 41, a mounting plate 42, a sliding rod 43, a movable clamping plate 44, a reset spring 45 and a handle 46, wherein the fixed clamping plate 41 and the mounting plate 42 are respectively fixedly arranged on both sides of the top of the placement plate 26, the sliding rod 43 slides through the mounting plate 42 and is fixedly connected to the movable clamping plate 44, the reset spring 45 is sleeved on the outside of the sliding rod 43 and is fixedly connected between the mounting plate 42 and the movable clamping plate 44, and the handle 46 is fixedly arranged on the top of the movable clamping plate 44.

[0045] In this way, the tool to be tested can be placed on the top of the placement plate 26, and then the movable clamping plate 44 is pulled by the handle 46, so that the movable clamping plate 44 drives the sliding rod 43 to move to the right, and at the same time the reset spring 45 is compressed, and then the tool to be tested is pushed to move it between the fixed clamping plate 41 and the movable clamping plate 44. At this time, the handle 46 is released, and then the compressed reset spring 45 drives the movable clamping plate 44 to cooperate with the fixed clamping plate 41 to clamp the tool to be tested.
