[0002] The existing valve core and workpiece installation process uses multiple assembly lines, which occupy a lot of space, require many operators, and result in high production costs. It also fails to centralize multiple processing steps, and overall efficiency needs improvement. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an integrated machine for automatic installation and airtightness testing of double angle valve cores.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An integrated machine for automatic installation and airtightness testing of double angle valve cores includes a frame, a turntable rotatably mounted at the top center of the frame, a synchronous belt for workpiece transport mounted on one side of the top of the frame, and a clamping mechanism, a locking mechanism, a pressing and rotating mechanism, and an air pressure detection mechanism sequentially mounted around the top of the frame, with the clamping mechanism and the synchronous belt located on the same side.

[0007] Optionally, the locking mechanism includes a mounting bracket, a telescopic rod is mounted on one side of the mounting bracket, a connecting plate is connected to the telescopic end of the telescopic rod, two rotating rods are mounted on the connecting plate, and a locking sleeve is connected to the bottom of the rotating rods through the connecting plate.

[0008] Optionally, conveyor belts are installed on both sides of the interior of the mounting frame, and limit plates are installed on both sides of the exterior of the mounting frame near the turntable. Push cylinders are also installed on the limit plates.

[0009] Optionally, the pressing and rotating mechanism includes an L-shaped top plate frame, with two rotating rods rotatably mounted on the bottom of the horizontal end of the top plate frame.

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-6 As shown, an integrated machine for automatic installation and airtightness testing of double angle valve cores includes a frame 1. A turntable 6 is rotatably installed at the top center of the frame 1. A synchronous belt 12 for workpiece transportation is installed on one side of the top of the frame 1. A clamping mechanism 5, a locking mechanism 2, a pressing and rotating mechanism 3, and an air pressure detection mechanism 4 are installed sequentially around the top of the frame 1. The clamping mechanism 5 and the synchronous belt 12 are located on the same side.

[0025] As a technical optimization of this utility model, the clamping mechanism 5 includes a transfer rod 15, with grippers 17 for picking up and placing workpieces installed at the bottom of both ends of the transfer rod 15, and a vertically arranged rotating shaft 16 connected to the middle of the bottom of the transfer rod 15, with the bottom of the rotating shaft 16 connected to the top of the frame 1.

[0026] As a technical optimization of this utility model, the locking mechanism 2 includes a mounting bracket 14. A telescopic rod 11 is mounted on one side of the mounting bracket 14. The telescopic end of the telescopic rod 11 is connected to a connecting plate 18. Two rotating rods 10 are mounted on the connecting plate 18. The bottom of the rotating rods 10 passes through the connecting plate 18 and is connected to a locking sleeve 21. The locking mechanism 2 can initially install the valve core and the workpiece, preventing the valve core from separating from the workpiece due to the subsequent rotation of the turntable 6.

[0027] As a technical optimization of this utility model, conveyor belts 13 are installed on both sides of the interior of the mounting frame 14, and limit plates 19 are installed on both sides of the exterior of the mounting frame 14 near the turntable 6. A push cylinder 20 is also installed on the limit plate 19. The limit plate 19 can limit the valve core on the conveyor belt 13, which facilitates the subsequent accurate push of the push cylinder 20.

[0028] As a technical optimization of this utility model, the pressing and rotating mechanism 3 includes an L-shaped top plate frame 24. Two rotating rods 23 are rotatably mounted on the bottom of the horizontal end of the top plate frame 24. A rotating sleeve 22 is connected to the bottom of the rotating rods 23. The bottom of the vertical end of the top plate frame 24 is connected to the top of the frame 1. The pressing and rotating mechanism 3 can fully and accurately install the valve core on the workpiece, ensuring that it is installed in place.

[0029] As a technical optimization of this utility model, the air pressure detection mechanism 4 includes a support frame. Two downward pressure cylinders 25 are installed on the top of the support frame, and the bottom of the support frame is connected to the bottom of the frame 1. A sealing head 26 is installed at the bottom of the downward pressure cylinders 25, and a telescopic air inlet pipe 27 is installed in the middle of the support frame. The downward pressure cylinders 25 drive the sealing head 26 to move downward, and the sealing head 26 seals the top of the valve core. One end of the telescopic air inlet pipe 27 on the other side extends into one end of the workpiece and engages with it to seal it. Then, gas is injected into the workpiece to detect the internal pressure of the workpiece, thereby determining whether the workpiece and the valve core are properly installed.

[0030] As a technical optimization of this utility model, four workstations 7 for placing workpieces are evenly installed on the top of the turntable 6. The bottom of the turntable 6 is connected to the frame 1 through a vertically arranged spindle 8, and the bottom end of the spindle 8 is connected to the top of the frame 1. The spindle 8 can drive the turntable 6 to rotate and stop, so that the workpieces on the workstations 7 can be processed in an orderly manner under each mechanism.

[0031] As a technical optimization of this utility model, a touch screen 9 is also installed on the top of the frame 1 near the synchronous belt 12. The touch screen 9 is electrically connected to the control system of the entire device, and the operation of the entire device can be controlled through the touch screen 9.

[0032] In use, the workpieces to be processed are placed sequentially on the synchronous belt 12. The synchronous belt 12 moves the workpieces towards one side of the clamping mechanism 5. When the workpieces reach the preset position on one side of the clamping mechanism 5, the synchronous belt 12 stops rotating. The gripper 17 at one end of the transfer rod 15 clamps a workpiece and places it into the corresponding station 7 below the clamping mechanism 5. Then, the gripper 17 disengages from the workpiece, and the turntable 6 rotates the station containing the workpiece to below the locking mechanism 2. The conveyor belt 13 moves the placed valve core towards one side of the turntable 6 in advance until the valve core at the very end contacts the limiting plate 19, at which point the conveyor belt 13 stops running. The push cylinder 20 pushes the valve core in contact with the limiting plate 19 outward, and the valve core enters the preset installation position on the workpiece. Then, the telescopic rod 11 moves the connecting plate 18 downward, and the locking sleeve 21 contacts the valve core. The rotating rod 10 drives the locking sleeve 21 to rotate, which in turn drives the valve core to rotate, locking the valve core and the workpiece.

[0033] After the valve core passes through the locking mechanism 2, the turntable 6 drives the workpiece containing the valve core to rotate below the pressing and rotating mechanism 3 and then stops rotating. The rotating rod 23 with telescopic function drives the rotating sleeve 22 to rotate and move downward. The rotating sleeve 22 drives the valve core to rotate and move downward into the interior of the workpiece to press it, so that the workpiece and the valve core are fully installed.

[0034] After the valve core and workpiece are installed, the turntable 6 rotates the installed workpiece to a position below the air pressure detection mechanism 4 and then stops rotating. The downward pressure cylinder 25 moves the sealing head 26 downward, sealing the top of the valve core. One end of the telescopic air inlet pipe 27 on the other side extends into one end of the workpiece and engages with it to seal it. Then, gas is injected into the workpiece to detect the internal pressure, thereby determining whether the workpiece and valve core are properly installed.

[0035] The above steps constitute the installation and inspection of one workpiece. Each time the turntable 6 rotates, the clamping mechanism 5 removes the installed and inspected workpiece from the station and places it onto the synchronous belt 12 for transport to the discharge end. It then clamps a workpiece to be processed from the synchronous belt 12 and places it on an empty station. This cycle is repeated to automate the assembly line installation and inspection of workpieces and valve cores.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
