[0035] First Embodiment

[0036] Please refer to the following: Figure 1 , Figure 2 and Figure 4 A valve processing turntable mounting device includes: a mounting frame 1, and a lifting device 11, wherein the lifting device 11 is mounted on the top of the mounting frame 1;

[0037] Rotating device 2, which is installed at the output end of lifting device 11, is used to adjust the position of the turntable;

[0038] Flattening structure 4, which is slidably mounted on the output end of the rotating device 2 via connecting structure 3, is used to press the turntable down so that it fits into the valve stem;

[0039] Placement structure 5, which is mounted on the rotating device 2, is used to place the turntable;

[0040] When installing the turntable, place the valve directly below the flattening structure 4, place the turntable on the placement structure 5, and start the lifting device 11. The output end drives the rotating device 2 to move downward. The rotating device 2 drives the flattening structure 4 downward through the connecting structure 3, and at the same time drives the turntable downward. The flattening structure 4 tightly fits the turntable with the valve stem. Then, start the rotating device 2 again, and the placement structure 5 drives the turntable to rotate on the top of the valve stem. When the keyway of the turntable aligns with the key on the valve stem, the flattening structure 4 presses the turntable downward to embed the key into the keyway. The rotating device 2 stops rotating, and then the turntable is placed on the valve stem. Through the cooperation of the rotating device 2 and the flattening structure 4, the turntable can be easily and quickly installed on the valve stem, improving installation efficiency.

[0041] Please refer to the following: Figure 1 , Figure 4 and Figure 5 The rotating device 2 includes a mounting box 21, a motor 22, a transmission shaft 23, and a gantry frame 24. The mounting box 21 is installed on the output end of the lifting device 11. The motor 22 is installed inside the mounting box 21. One end of the transmission shaft 23 is fixedly installed on the output end of the motor 22. The other end of the transmission shaft 23 passes through the mounting box 21 and is fixedly installed on the gantry frame 24.

[0042] During turntable installation, the turntable is placed on the placement structure 5, and the lifting device 11 is started. The output end drives the mounting box 21 to move downward. The mounting box 21 drives the transmission shaft 23 and the gantry frame 24 to move. The gantry frame 24 drives the placement structure 5 and the turntable to move. At the same time, the gantry frame 24 drives the flattening structure 4 to move through the connecting structure 3, so that the turntable and the valve stem are tightly fitted. The motor 22 is started, and the output end drives the gantry frame 24 to rotate through the transmission shaft 23. The gantry frame 24 drives the placement structure 5 and the turntable to rotate, so as to align the keyway of the turntable with the key.

[0043] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The connecting structure 3 includes a connecting rod 31, a limiting plate 32, and a sliding hole 321. One end of the connecting rod 31 is fixedly connected to the lower part of the gantry frame 24, and the other end of the connecting rod 31 is fixedly installed with the limiting plate 32. The limiting plate 32 is provided with a plurality of sliding holes 321 at equal intervals.

[0044] When the turntable is installed, the lifting device 11 is started, and the gantry 24 drives the connecting rod 31 to move downward. The connecting rod 31 drives the limiting plate 32 and the flattening structure 4 to move downward. When the flattening structure 4 contacts the turntable, the lifting device 11 continues to work, and the flattening structure 4 slides upward in the sliding hole 321. At the same time, the flattening structure 4 applies pressure to the turntable to achieve the effect of pressing the turntable and the valve stem to fit tightly.

[0045] Please refer to the reference again. Figure 1 , Figure 2 and Figure 4 The flattening structure 4 includes a slide rod 41, a limiting block 42, a first elastic element 43, and a pressure plate 44. The slide rod 41 is slidably installed in the sliding hole 321. The limiting block 42 is installed on the slide rod 41 and is located above the sliding hole 321. The pressure plate 44 is fixedly installed at the bottom of the slide rod 41. The first elastic element 43 is installed between the pressure plate 44 and the limiting plate 32 and is sleeved on the slide rod 41.

[0046] When installing the turntable, after starting the lifting device 11, the limiting plate 32 drives the slide rod 41 and the pressure plate 44 to move downward. The pressure plate 44 pushes the turntable to contact the valve stem. The lifting device 11 continues to work, and the valve stem and the turntable push the pressure plate 44 to move upward. The pressure plate 44 drives the slide rod 41 to slide upward in the sliding hole 321. The pressure plate 44 squeezes the first elastic element 43. The first elastic element 43 pushes the pressure plate 44 to make the turntable and the valve stem fit tightly. When the turntable rotates on the valve stem, the keyway and the key are aligned. The pressure plate 44 pushes the turntable downward so that the key is embedded in the keyway. At this time, the motor 22 stops working. The pressure plate 44 pushes the turntable to install on the valve stem. After the installation is completed, the lifting device 11 moves upward, and the first elastic element 43 pushes the pressure plate 44 and the slide rod 41 downward. When the limiting block 42 contacts the limiting plate 32, the limiting block 42 limits the slide rod 41 to prevent the pressure plate 44 from falling off.

[0047] Please refer to the following: Figure 1 and Figure 4 The placement structure 5 includes a placement plate 51 and a stop block 52. Two placement plates 51 are symmetrically installed on the bottom of the inner wall of the gantry frame 24, and the stop block 52 is installed on both placement plates 51.

[0048] During turntable installation, the turntable is placed on the placement plate 51 and inserted into the inner side of the outer ring of the turntable by the stop block 52. When the starter motor 22 drives the gantry 24 to rotate, the gantry 24 drives the placement plate 51 to rotate, and the placement plate 51 drives the stop block 52 to rotate. The stop block 52 contacts the connection part between the outer and inner rings of the turntable, causing the turntable to rotate, so that the keyway of the turntable is aligned with the key on the valve stem, and the turntable is fitted onto the valve stem.

[0049] Second Embodiment

[0050] Please refer to the following: Figure 6 and Figure 7 The valve processing turntable mounting device further includes a limiting component 6, which is mounted on the placement plate 51 and is used to limit the turntable.

[0051] In this embodiment, the placement plate 51 is slidably mounted on the gantry frame 24, and the limiting component 6 is mounted on the other side of the gantry frame 24, symmetrical to the stop block 52. When the turntable is placed on the placement plate 51, the stop block 52 engages and is inserted into the inner side of the outer ring of the turntable. The limiting component 6 drives the placement plate 51 to slide within the gantry frame 24, and the placement plate 51 drives the stop block 52 to move, so that the stop block 52 is tightly fitted with the turntable, limiting the turntable and preventing it from falling off during installation. At the same time, it can limit turntables of different diameters.

[0052] Please refer to the reference again. Figure 6 and Figure 7 The limiting component 6 includes a baffle 61 and a second elastic member 62. The baffle 61 is installed at one end of the placement plate 51, and the second elastic member 62 is installed between the baffle 61 and the gantry frame 24 and is sleeved on the placement plate 51.

[0053] When the turntable needs to be placed on the placement plate 51, push the baffle 61 to move the placement plate 51 to the inside of the gantry 24. The placement plate 51 moves the stop block 52. After the stop block 52 is inserted into the outer ring of the turntable, release the baffle 61. The second elastic element 62 pushes the baffle 61 to move the placement plate 51 to the outside of the gantry 24, so that the stop block 52 fits tightly with the inner side of the outer ring of the turntable, thereby limiting the turntable. At the same time, it can adapt to turntables of different diameters and achieve better use results.

[0054] Please refer to the following: Figure 2 and Figure 4 The flattening structure 4 also includes an anti-slip pad 45, which is installed on the bottom of the pressure plate 44;

[0055] When the lifting device 11 is activated and moves downward, the pressure plate 44 causes the anti-slip pad 45 to fit tightly against the top of the turntable, preventing the turntable from slipping and falling off during rotation.

[0056] The working principle of the valve processing turntable mounting device provided by this utility model is as follows:

[0057] When installing the turntable, place the valve directly below the pressure plate 44, place the turntable on the placement plate 51, and insert the stop block 52 into the inner side of the outer ring of the turntable. Start the lifting device 11, and the output end drives the installation box 21 to move downward. The installation box 21 drives the drive shaft 23 and the gantry 24 to move. The gantry 24 drives the placement plate 51 and the turntable to move. At the same time, the gantry 24 drives the connecting rod 31 and the limiting plate 32 to move downward. The limiting plate 32 drives the sliding rod 41 and the pressure plate 44 to move downward. The pressure plate 44 pushes the turntable to contact the valve stem. The lifting device 11 continues to work, and the valve stem and the turntable push the pressure plate 44 upward. 44 drives the slide bar 41 to slide upward in the slide hole 321, squeezing the first elastic element 43. At the same time, the first elastic element 43 pushes the pressure plate 44 to make the turntable fit tightly with the valve stem. When the motor 22 is started, the gantry 24 drives the placement plate 51 and the stop block 52 to rotate. The stop block 52 contacts the connection part between the outer ring and the inner ring of the turntable, causing the turntable to rotate. When the turntable rotates on the valve stem, and the keyway is aligned with the key, the pressure plate 44 pushes the turntable downward, so that the key is embedded in the keyway. At this time, the motor 22 stops working, and the pressure plate 44 pushes the turntable to install on the valve stem, achieving the purpose of conveniently and quickly installing the turntable onto the valve stem and improving installation efficiency. A second elastic element 62 is provided. When the turntable is placed on the placement plate 51, the baffle 61 is pushed, causing the placement plate 51 to slide inward toward the gantry 24. The placement plate 51 drives the stop block 52 to move. After the stop block 52 is inserted into the outer ring of the turntable, the baffle 61 is released. The second elastic element 62 pushes the baffle 61, causing the placement plate 51 to slide outward toward the gantry 24, so that the stop block 52 fits tightly with the inner side of the outer ring of the turntable, thereby achieving the effect of limiting the turntable. At the same time, it can adapt to turntables of different diameters and achieve better use results.
