[0025] Example 1

[0026] like Figure 1-4As shown, a valve stem mounting device according to an embodiment of the present invention includes a fixed mounting bracket 1 and a movable mounting bracket 2. The movable mounting bracket 2 is mounted on the top left side of the fixed mounting bracket 1. A driver 3 is fixedly connected to the top of the fixed mounting bracket 1, and a screw seat 4 is connected to the bottom of the driver 3. A placement tray 5 is fixedly connected to the bottom side of the inner wall of the movable mounting bracket 2. A rubber sealing ring 6 is embedded and fixed inside the placement tray 5. An assembly seat 7 is fixedly connected to the top of the fixed mounting bracket 1. A first servo motor 8 is fixedly connected to the cavity of the bottom side of the inner wall of the fixed mounting bracket 1, and a rectangular groove 9 is carved out on the bottom side of the inner wall.

This can automatically assemble the valve nozzle parts without the need for workers to manually pick up multiple parts for alignment and waiting for the core to be installed, greatly improving its practicality.

[0027] Example 2

[0028] like Figure 1-4As shown, a valve stem mounting device according to an embodiment of the present invention includes a fixed mounting bracket 1 and a movable mounting bracket 2. The movable mounting bracket 2 is mounted on the top left side of the fixed mounting bracket 1. A driver 3 is fixedly connected to the top of the fixed mounting bracket 1, and a screw seat 4 is connected to the bottom of the driver 3. A placement tray 5 is fixedly connected to the bottom side of the inner wall of the movable mounting bracket 2. A rubber sealing ring 6 is embedded and fixed inside the placement tray 5.

The valve core and valve nozzle can be quickly inserted and connected, which can ensure that the valve core insertion depth is appropriate. Under the action of the buffer spring 17, the insertion flexibility can be ensured, avoiding the valve core breakage caused by rapid impact insertion, and the safety is further improved.

[0029] Example 3

[0030] like Figure 1-4As shown, a valve stem mounting device according to an embodiment of the present invention includes a fixed mounting bracket 1 and a movable mounting bracket 2.

The movable end of the telescopic cylinder 18 is fixedly connected to the connecting block 19, and the bottom side of the connecting block 19 is fixedly connected to the top side of the screwing seat 4. The screwing seat 4 includes a housing 20 and a second servo motor 21. The top right side of the housing 20 is fixedly connected to the second servo motor 21, and the inner walls of the housing 20 are connected by a shaft. A rotating shaft 22 is connected to the housing 20, with its bottom end penetrating the bottom side of the housing 20 and a valve core wrench 23 fixedly connected thereto. The output shaft of the second servo motor 21 extends into the housing 20, and gears 24 are respectively fitted and fixed on the outer wall of the second servo motor 21 and the outer wall of the rotating shaft 22. The gears 24 are matched and meshed with each other. When the valve core and valve nozzle are inserted, the valve core wrench 23 at the bottom of the housing 20 will connect with the top of the valve core.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, by starting the first servo motor 8, the output shaft of the first servo motor 8 drives the lead screw 10 to rotate. Under the guidance and limiting action of the guide rod 11 on the moving block 12, and the action of the lead screw nut inside the moving block 12, the lead screw 10 and the moving block 12 outside the guide rod 11 can drive the movable mounting frame 2 to move laterally. This allows the movable mounting frame 2 to drive the assembled valve nozzle housing into the fixed mounting frame 1, and to be aligned with the mounting base 7, the driver 3, and the screwing seat 4 on the same axis. This allows the valve core to be inserted and fixed to the limiting tube 15 of the mounting base 7. During the compression and limiting process, the driver 3 drives the screw seat 4 to press down, so that the screw seat 4 abuts against the top of the valve core inside the limiting tube 15, so that the limiting tube 15 passes through the inside of the fixed mounting bracket 1, and the valve core is inserted into the valve nozzle housing inside the placement plate 5. When the valve core and valve nozzle are inserted, the valve core wrench 23 at the bottom of the housing 20 will connect with the top of the valve core, start the second servo motor 21, and the gear 24 on the outer wall of the output shaft of the second servo motor 21 meshes with the gear 24 on the outer wall of the rotating shaft 22, which can drive the valve core wrench 23 to rotate, so that the valve core can be screwed on directly after insertion.
