[0016] like Figures 1 to 4As shown, an auxiliary device for pressing a specific gravity cup includes a workbench 1, on which a placement plate 2 is provided. The placement plate 2 has a cup placement area for placing the cup body of the specific gravity cup and a lid placement area for placing the lid of the specific gravity cup. An overflow hole is provided at the center of the lid. A clamping member for clamping the cup body is provided on the cup placement area. A positioning telescopic rod for positioning the lid is provided on the lid placement area, which is configured to cooperate with the overflow hole. A connecting frame 3 is provided on one side of the placement plate 2. A moving cylinder 4 for horizontal movement is provided on the connecting frame 3. The output axis of the moving cylinder 4 is horizontally arranged. A pressing cylinder 5 is connected to the output end of the moving cylinder 4. The output shaft of the pressing cylinder 5 is connected to a pressing plate 6 located directly above the placement plate 2. The pressure plate 6 is vertically positioned, with a slot 7 in the middle of its lower end. A receiving cavity 8 communicating with the slot 7 is provided within the pressure plate 6. A movable component 9 is mounted on the pressure plate 6, and its output end is connected to a positioning conical rod 11 located within the slot 7. The movable component 9 controls the positioning conical rod 11 to move downwards, allowing it to pass through an overflow hole in the center of the cover. A toggle switch 14 is provided within the receiving cavity 8, and a toggle plate is rotatably mounted on the toggle switch 14. The toggle plate is hinged to the positioning conical rod 11. Multiple suction cups 12 are evenly distributed on the lower end face of the pressure plate 6. A pump body 13, connected to the suction cups 12 via a pipe 15, is mounted on the pressure plate 6. The toggle switch 14 is connected to the pump body 13, and a pressure sensor is located at the connection between the pipe 15 and the pump body 13.

[0017] Place the lid on the lid placement area and the cup on the cup placement area. The clamping device clamps and fixes the cup. When the moving cylinder 4 retracts and resets, the pressure plate 6 is directly above the lid. The pressing cylinder 5 extends and moves the pressure plate 6 downward. The positioning cone rod 11 on the pressure plate 6 passes through the overflow hole in the center of the lid. The moving device 9 controls the positioning cone rod 11 to retract into the slot 7. At this time, the suction cup 12 on the lower end face of the pressure plate 6 contacts the lid. The positioning cone rod 11 moves and moves the toggle plate. The toggle switch 14 is turned on. The toggle switch 14 is the air circuit on / off switch. The pump body 13 is started and the pump body 13 draws a vacuum. The suction cup 12 is adsorbed and connected to the lid to fix the lid. After the pressure plate 6 fixes the lid, the pressing cylinder 5 retracts and the moving cylinder 4 extends, so that the pressure plate 6 is directly above the cup. The pressing cylinder 5 extends and puts the lid on the cup. When pressing the lid down, the force is uniform, which improves the accuracy of the test results.

[0018] When the toggle switch 14 is turned on, the pump body 13 continues to work and draws air inward. The pump body 13 is connected to the air passage of the suction cup 12 through the pipe 15, and the air inside the suction cup 12 is drawn away from the pump body 13 along the pipe 15. The air inside the suction cup 12 is drawn out, forming a negative pressure vacuum. The suction cup 12 is tightly attached to the cover and firmly sucked by the atmospheric pressure difference. The pressure sensor detects the negative pressure value of the pipe 15 in real time, which can determine whether the cover is sucked in and whether there is a leak.

[0019] The movable component 9 includes a movable telescopic cylinder disposed on the pressure plate 6. The telescopic end of the movable telescopic cylinder is connected to the positioning cone rod 11 via a movable rod 10. A slide rail is provided in the slot 7 that is slidably connected to the movable rod 10. The extension of the movable telescopic cylinder is used to control the positioning cone rod 11 to move downward, so that it can be inserted into the overflow hole in the center of the cover, which facilitates the center positioning of the cover.

[0020] The aforementioned movable component 9 is replaceable and can be replaced by a movable motor. The output end of the movable motor is connected to an output shaft, and a rotating gear is provided on the output shaft. A rack is meshed and driven on one side of the rotating gear. The rack is vertically arranged, and a track is provided on the inner side wall of the receiving cavity 8 to slide and connect with the rack. The lower end of the rack is connected to the positioning cone rod 11 through a movable rod 10. When the movable motor is started, the output shaft and the rotating gear rotate. Through the meshing and transmission between the rotating gear and the rack, the positioning cone rod 11 moves downward and extends into the overflow hole in the center of the cover, which facilitates the center positioning of the cover.

[0021] The clamping component includes a driving component 17 and two symmetrically arranged clamping plates 16. The driving component 17 is used to control the two clamping plates 16 to move towards each other to clamp the cup or to move in opposite directions to release the cup.

[0022] The driving component 17 includes a first driving motor, the output end of which is connected to a lead screw. A limiting component parallel to the lead screw is provided on the cup placement area. The lead screw has two threaded sections with opposite thread directions. Each threaded section has a slider that is slidably connected to the limiting component. The two sliders are respectively connected to two clamping plates 16. The limiting component can be a limiting rod or a limiting groove. When the first driving motor is started, it drives the lead screw to rotate, causing the two sliders to move towards each other, which in turn causes the two clamping plates 16 to move towards each other to clamp the cup.

[0023] The aforementioned drive component 17 is replaceable. The drive component 17 can be replaced by a second drive motor. The output end of the second drive motor is connected to a drive shaft. A driven shaft is provided on one side of the drive shaft. A first gear is provided on the drive shaft. A second gear that meshes with the first gear is provided on the driven shaft. Both clamping plates 16 are rotatably disposed in the cup placement area via swing shafts. The two swing shafts are respectively connected to the drive shaft and the driven shaft. When the second drive motor is started, it drives the drive shaft to rotate. Through the meshing of the first gear and the second gear, it drives the driven shaft to rotate. The rotation direction of the driven shaft is opposite to the rotation direction of the drive shaft, thereby causing the two clamping plates 16 to swing towards each other to clamp the cup.

[0024] The two types of driving components 17 described above can also be replaced. The driving component 17 includes two driving telescopic rods. The telescopic ends of the two driving telescopic rods are arranged facing each other and are respectively connected to two clamping plates 16. The extension of the driving telescopic rods is used to control the two clamping plates 16 to move towards each other to clamp the cup. Example
