[0022] An embodiment of the present utility model provides a pneumatic device for assembling an O-ring inside a valve, as Figures 1-5 shown. The pneumatic device for assembling an O-ring inside a valve includes: a processing table 1, on the top of the tabletop of the processing table 1, a mounting bracket 2 is fixedly installed; a cylinder 3, the cylinder 3 is fixedly installed on the inner wall of the top of the mounting bracket 2, and a pressing head 4 is arranged on the output rod of the cylinder 3; a mounting plate 5, the mounting plate 5 is horizontally arranged below the tabletop of the processing table 1, a rotatable mounting disc 6 is arranged on the mounting plate 5, and a plurality of groups of assembly plates 7 are fixedly installed around the center of the top of the mounting disc 6, each group of assembly plates includes two assembly plates distributed at intervals; a first fixture plate 8 and a second fixture plate 9, the first fixture plate 8 and the second fixture plate 9 are respectively arranged on the two assembly plates 7 of each group and are opposite to each other; a window, the window is opened on the tabletop of the processing table and matches the size of the mounting disc, and the upper parts of the plurality of groups of assembly plates extend out of the window to above the tabletop of the processing table; a driving mechanism, the driving mechanism is arranged on the mounting plate 5 and is used to drive the mounting disc 6 to rotate, so as to switch the position of the valve body 17 to directly below the pressing head 4.
[0023] In this embodiment, in the preparation stage: First, place the valve body 17 to be assembled between the first fixture plate 8 and the second fixture plate 9. According to the specific size of the valve body 17, flexibly adjust the distance between the two fixture plates to ensure that the valve body is stable and not easily shaken; pre-place the O-ring: Subsequently, pre-place the O-ring 18 near the sealing ring groove of the valve body 17 to prepare for the subsequent pressing and assembling; start the assembly process: Start the cylinder 3, and its output rod will immediately drive the pressure head 4 to move downward and enter the standby state, ready to press and assemble the O-ring; at the same time, the driving mechanism is started, and the driving mechanism drives the mounting disc 6 to rotate slowly. This action accurately rotates the assembly plate 7 with the valve body 17 to directly below the pressure head 4 to ensure the accuracy of the assembly position; when the valve body 17 reaches the designated position (directly below the pressure head 4), the cylinder 3 continues to push the pressure head 4 downward to accurately and quickly press the O-ring 18 into the sealing ring groove of the valve body 17 with a stable and uniform force; after one assembly is completed, the driving mechanism drives the mounting disc 6 to rotate again, automatically rotating the next valve body 17 to be assembled to directly below the pressure head 4 to achieve a continuous and efficient assembly process; after the assembly is completed, the operator can easily remove the valve body 17 with the assembled O-ring for subsequent quality inspection; through strict quality inspection, it is ensured that each O-ring 18 meets the assembly requirements, effectively avoiding leakage problems caused by improper assembly; the introduction of the pneumatic device to assist in the assembly greatly reduces the time and labor intensity of manual operation and significantly improves the assembly efficiency; the design of the pressure head 4 and the cylinder control ensure the accurate pressing of the O-ring, and at the same time, the design of the fixture plate also ensures the stability of the valve body 17 during the assembly process, reducing the assembly error; the first fixture plate 8 and the second fixture plate 9 with adjustable spacing can adapt to valve bodies of different sizes, improving the versatility and flexibility of the device.
[0024] In a further preferred embodiment of the present utility model, the driving mechanism includes: a bearing seat 10 fixedly installed at the center of the mounting plate 5; a rotating shaft 11 vertically and rotatably installed on the bearing seat 10, the top end of the rotating shaft 11 being fixedly connected to the mounting disc 6; a motor 12 fixed to the bottom of the mounting plate 5, the output shaft of the motor 12 being fixedly connected to the bottom end of the rotating shaft 11 through a coupling.
[0025] In this embodiment, the motor 12 is directly connected to the rotating shaft 11 through a coupling, reducing energy loss during power transmission and improving driving efficiency. This design makes the rotation of the mounting plate 6 more stable and rapid, thus accelerating the assembly speed. The motor 12 is usually equipped with an accurate control system, which can achieve precise control of the rotation speed and rotation angle. This means that during the assembly process, the rotation position of the valve body 17 can be precisely controlled to ensure that it can accurately reach directly below the indenter 4 for assembly. By driving the mounting plate 6 to rotate through the motor, the automation or semi-automation of the assembly process is realized. This not only reduces the need for manual operation but also reduces the labor intensity and improves the production efficiency. The stable design of the bearing seat 10 and the rotating shaft 11 ensures the stability of the driving mechanism during long-term operation. This stability is of great significance for ensuring the assembly accuracy and extending the service life of the equipment. By driving the rotating shaft to rotate through the motor 12, the automatic switching position of the mounting plate and the valve body 17 thereon is realized, further improving the assembly efficiency and automation level.
[0026] In a further preferred embodiment of the present utility model, a plurality of brackets 13 are fixedly installed around the center at the top of the mounting plate 5, and balls 14 are embedded at the tops of the plurality of brackets 13.

[0027] In this embodiment, the brackets 13 are symmetrically and fixedly installed at the top of the mounting plate 5, providing a stable support platform for the balls 14. The design of the brackets should ensure that they can bear the weight of the mounting plate 6 and all the components thereon and remain stable during rotation. The balls 14 are embedded at the tops of the brackets 13 and are adapted to the annular groove at the bottom of the mounting plate 6. The presence of the balls greatly reduces the frictional resistance during the rotation of the mounting plate 6, making the rotation smoother and more labor-saving. The annular groove is formed at the bottom of the mounting plate 6 and is in close cooperation with the balls 14. The design of the annular groove should ensure that the balls can roll freely therein while maintaining a certain stability to prevent the mounting plate from shifting or shaking during rotation. When the driving mechanism (such as the motor 12) is started to drive the rotating shaft 11 to rotate, the mounting plate 6 will rotate accordingly. At this time, the annular groove at the bottom of the mounting plate 6 interacts with the balls 14 at the tops of the brackets 13, and the balls roll in the annular groove, providing a smooth sliding path for the rotation of the mounting plate. This design makes the rotation of the mounting plate 6 more stable.
[0028] In a further preferred embodiment of the present utility model, circular holes and strip holes 15 are respectively formed in the first clamping plate 8 and the second clamping plate 9, bolts 16 are arranged in both the circular holes and the strip holes 15, and the bolts 16 are threadedly connected to the corresponding assembly plate 7.
[0029] In this embodiment, the introduction of the strip-shaped hole 15 enables the second fixture plate 9 to move along the length direction of the strip-shaped hole, thereby adjusting the spacing from the first fixture plate 8. This adjustment method is very intuitive and easy to operate: First, it is necessary to loosen the bolts 16 that penetrate the strip-shaped hole 15 and are threadedly connected to the assembly plate 7. This step is the key to unlocking; after the bolts are loosened, the second fixture plate 9 can be freely moved until the desired spacing position is reached; when the second fixture plate 9 is moved to the appropriate position, the bolts 16 are tightened again to make them tightly connected to the assembly plate 7; in this way, the adjustment of the spacing between the first fixture plate 8 and the second fixture plate 9 is completed.
[0030] In a further preferred embodiment of the present utility model, rubber pads are provided on the mutually approaching surfaces of the first fixture plate 8 and the second fixture plate 9 for anti-slip.
[0031] In this embodiment, the design of adding rubber pads on the mutually approaching surfaces of the first fixture plate 8 and the second fixture plate 9. These rubber pads have good anti-slip performance, reducing the risk of the placed valve body 17 slipping.
[0032] In a further preferred embodiment of the present utility model, a concave block is fixedly installed at the top end of the output rod of the cylinder 3 for installing the pressing head 4. A screw is provided on the concave block, and the screw threadedly penetrates the pressing head 4.
[0033] In this embodiment, the cylinder 3 is used as a driving component, and a concave block is fixedly installed at the top end of its output rod. A screw hole is provided on the concave block, and the screw threadedly penetrates the pressing head 4, thereby firmly fixing the pressing head 4 on the concave block.
[0034] In a further preferred embodiment of the present utility model, two support frames are fixedly installed at the bottom of the processing table 1, and the mounting plate 5 is fixedly connected to the two support frames.
[0035] In this embodiment, the support frames are fixedly installed at the bottom of the processing table 1 to provide stable support for the processing table and ensure its stability during the assembly process; the fixed connection between the inner wall of the support frame and the mounting plate 5: The mounting plate 5 is firmly fixed on the inner wall of the support frame by welding, bolt connection or other fastening methods to ensure its stability and reliability.
[0036] In summary, through the design of the indenter 4 and the control of the cylinder 3, it is ensured that the O-ring 18 is accurately and quickly pressed into the sealing ring groove of the valve body 17 to complete the assembly, improving the assembly efficiency. By driving the rotating disc 6 to rotate by the motor 12 and combining with the precise downward pressing of the indenter 4 controlled by the cylinder 3, the automatic or semi-automatic assembly of the valve body 17 and the O-ring 18 is realized. This process reduces the manual operation time and labor intensity. The bracket 13 provides a stable support platform for the ball 14, and the ball fits tightly with the annular groove at the bottom of the rotating disc 6, greatly reducing the frictional resistance during rotation and making the rotation of the rotating disc 6 smoother and more stable. This design ensures the stability and reliability of the assembly process.
