Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0025] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0027] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0029] Embodiment:

[0030] Reference Figures 1 - 3 , a driving mechanism for a sealing detection mechanism, comprising: a base 1 installed on the fixture bottom plate and a spherical bearing joint 2 installed on the fixture top plate. A driving shaft 3 is rotatably connected to the base 1 through a bearing. The two bases 1 are arranged oppositely for installing and supporting the driving shaft 3. A lever 4 is fixedly connected to the driving shaft 3. An end effector 5 for driving the sealing detection mechanism is installed on the lever 4. A swing arm 6 for controlling the rotation angle of the driving shaft 3 is connected to the driving shaft 3. One end of the swing arm 6 is connected to a first sleeve 7, and the other end of the first sleeve 7 is connected to the spherical bearing joint 2. When the top plate moves relatively up and down with respect to the bottom plate, it drives the first sleeve 7 to move up and down, thereby pressing down one end of the swing arm 6. Further, the swing arm 6 drives the driving shaft 3 to rotate, so that the driving shaft 3 drives the lever 4 to swing, and the lever 4 drives the end effector 5 to swing, so that the end effector 5 drives the sealing detection mechanism. By arranging multiple such driving mechanisms between the same bottom plate and top plate, only one reciprocating linear motion of a cylinder can be used to drive multiple sealing detection mechanisms in different directions to simultaneously seal the side holes of the middle frame of the mobile phone shell.

[0031] Reference Figures 1 - 3 , a guide rod 71 is slidably fitted in the first sleeve 7. The lower end of the guide rod 71 is connected to a connecting sleeve 8. The connecting sleeve 8 is slidably fitted with the first sleeve 7. A compression spring 72 is abutted between the connecting sleeve 8 and the first sleeve 7. The swing arm 6 is hinged to the connecting sleeve 8. Thus, the compression spring 72 applies a force to the swing arm 6 through the connecting sleeve 8. Further, the first sleeve 7 elastically and flexibly presses down the swing arm 6 through the compression spring 72, avoiding indirect damage or extrusion deformation to the workpiece to be measured caused by excessive downward pressure compared with hard pressing.

[0032] Reference Figures 1 - 3, a pre-tightening nut 74 is threadedly connected to the first sleeve 7. One end of the compression spring 72 abuts against the pre-tightening nut 74, and the other end abuts against the connecting sleeve 8, thereby adjusting the pressure of the connecting sleeve 8 on the swing arm 6, and further finely adjusting the pressure of the compression spring as a whole. By changing the position of the pre-tightening nut 74, the compression amount of the compression spring 72 is adjusted, and then the pressure on the sealing performance detection mechanism is changed to meet different sealing pressure requirements.

[0033] Reference Figures 1 - 3 , a sliding compression ring 81 is sleeved on the connecting sleeve 8. The sliding compression ring 81 is in sliding fit with the connecting sleeve 8. A pre-tightening spring 82 is abutted between the connecting sleeve 8 and the sliding compression ring 81. Both ends of the compression spring 72 abut against the pre-tightening nut 74 and the sliding compression ring 81 respectively. The sliding compression ring 81 plays a role in force bearing and support. Through the further arranged pre-tightening spring 82, the sealing performance detection mechanism can be pre-pressed on the hole to be measured, and when the first sleeve 7 is pressed down, it can be fully pressed on the hole to be measured, ensuring the accuracy of position and sealing performance.

[0034] Reference Figures 1 - 3 , the upper end of the first sleeve 7 is adjustably connected with an adjusting sleeve 9. For example, the adjusting sleeve 9 is threadedly connected to the first sleeve 7, the ball head bearing joint 2 is connected to the adjusting sleeve 9, and a force application plane 91 matched with a wrench is provided on the outer edge of the adjusting sleeve 9. Thus, when the overall stroke needs to be adjusted, the adjusting sleeve 9 is rotated by using a wrench to clamp the force application plane 91, thereby adjusting the stroke of the driving mechanism.

[0035] Reference Figures 1 - 3 , a bushing 73 is installed in the first sleeve 7. The guide rod 71 is in sliding fit with the bushing 73. A limiting block 711 extends on the guide rod 71. The size of the limiting block 711 is larger than the inner hole size at the upper end face of the bushing 73, thereby preventing the guide rod 71 from falling off the bushing 73.

[0036] Operation process: Under the action of the pre-tightening spring 82, a certain pre-driving force is provided for the sealing performance detection mechanism, so that the sealing performance detection mechanism can be pre-pressed on the hole to be detected. When the top plate and the bottom plate move relatively up and down, the compression spring 72 is compressed, and the pressure is transmitted to the swing arm 6. The swing arm 6 drives the drive shaft 3 to rotate (the rotation amplitude is very small), thereby driving the swing of the dial rod 4 (the swing distance is very small, in millimeters), and then driving the sealing performance detection mechanism to press or loosen the hole.

[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
