[0038] Airtightness detection and hydraulic clamping are carried out simultaneously. After the workpiece is placed, the worker presses the knob, at which time the gas supply structure transports gas, so that the gas reaches the detection base on the gas path of the detection base. A small hole is formed in the detection head for airtightness detection. During detection, the PLC control of the clamping mechanism is used to determine whether the air pressure leakage value on the detection head exceeds the preset value. If the preset value is exceeded, the PLC control system will alarm, prompting the operator that the bearing cover is not clamped well. When the preset value is not exceeded, the clamping mechanism operates normally, thereby achieving the effect of airtightness detection.

[0089] The centering structure 3 is arranged on one side of each clamping position 100, and the two centering structures 3 are centrally symmetric about the center point of the clamping position 100. This layout ensures that the forces on both sides of the clamping position 100 are balanced, which helps to achieve more accurate centering alignment. When the centering driving member 31 is activated, it drives the toggle member 32 to rotate around its axis. Since the two centering structures 3 are centrally symmetric about the center point of the clamping position 100, their rotation will work together to align the clamping position 100 and the bearing cover (or other clamped objects) on it to the center position.

[0090] Through the rotation adjustment of the centering structure 3, it can be ensured that the bearing cover always remains in the center position during clamping, thereby improving the accuracy and stability of clamping. This is crucial for subsequent machining operations, helping to reduce machining errors and improve product quality.

When the bearing cover (or other clamped object) is placed on the clamping position 100, the position of the first positioning head 62 matches the positioning hole or positioning surface of the bearing cover, so as to realize the accurate positioning of the bearing cover. During clamping, the first positioning structure 6 cooperates with the centering structure 3 to firmly fix the bearing cover on the clamping position 100. The first positioning head 62 enhances the stability of clamping by limiting the movement of the bearing cover in a specific direction. The shape and size of the first positioning head 62 can be customized according to the positioning needs of different bearing covers (or other clamped objects), thereby improving the adaptability and flexibility of the clamping mechanism.

[0096] This embodiment is improved on the basis of Embodiment 5.

[0097] As shown in the figure, in this embodiment, it also includes a gas tightness detection system 5, which includes a detection base 51 and a detection head 52.

[0099] ​​The air tightness detection and hydraulic clamping are simultaneously performed. After the workpiece is placed, the worker presses the knob. At this time, the gas supply structure will transport the gas to make the gas reach the detection base 51 on the gas path of the detection base 51. A small hole is formed in the detection head 52 for air tightness detection. During the detection process, whether the air pressure leakage value on the detection head 52 exceeds the preset value is judged through the PLC control of the clamping mechanism. If the preset value is exceeded, the PLC control system will alarm, prompting the operator that the bearing cover is not clamped well. When the preset value is not exceeded, the clamping mechanism normally operates, so that the air tightness detection function is achieved. The air tightness detection system 5 can achieve the purpose of whether the bearing is in place and whether the clamping is wrong, and has a certain foolproof function.

[0101] This embodiment is improved on the basis of embodiment 6.

[0102] As shown in Figures 1-5 In this embodiment, a second positioning structure is further included, which comprises a second positioning driving member 81 and a second positioning head 82. The second positioning driving member 81 is arranged below the clamping position 100, and the second positioning head 82 is fixed to the output end of the second positioning driving member 81. The second positioning driving member 81 drives the second positioning head 82 to ascend and descend.

[0103] The introduction of the second positioning structure enables the device to achieve more accurate positioning when clamping the object. By controlling the ascending and descending of the second positioning head 82, the second positioning head 82 can enter or leave the clamping position 100. The second positioning structure cooperates with the first positioning structure 6 to interact, so as to achieve comprehensive positioning of the workpiece.

[0104] In this embodiment, an air tightness detection port 821 is arranged on the second positioning head 82, and the air tightness detection port 821 is arranged towards the clamping position 100.

[0105] Similar to the detection head 52, the air tightness detection port 821 is also connected with the PLC control system. The PLC control system can monitor the air pressure change at the air tightness detection port 821 in real time, and compare it with the preset air pressure threshold value. If the air pressure decreases by more than the preset threshold value, the PLC control system will judge that the workpiece is not clamped in place or there is an air tightness problem, and immediately issue an alarm signal to prompt the operator to check and adjust. According to the alarm signal, the operator can quickly locate the problem and re-clamp or adjust the workpiece. After the adjustment is completed, the air tightness detection is performed again to ensure that the workpiece is correctly and tightly clamped on the clamping position 100. The air tightness detection port 821 and the small hole on the detection head 52 together constitute a double and multi-point detection system, which improves the accuracy and reliability of the detection.

[0106] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0107] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0108] In addition, it needs to be explained that the use of "first", "second" and the like to limit the parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning if there is no further declaration, so it cannot be understood as a limitation on the protection scope of the application. The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
