The material feeding port 33 is fixedly connected to the upper machine support 2 and is located at the lower end of the turntable 3.

[0027] In this embodiment, the corresponding parts are conveyed to the turntable 3 by the first conveyor belt 5. The rotation of the turntable 3 is used to convey the parts to different working positions. The turntable 3 is provided with a locking position to effectively prevent the parts from rotating and falling during the rotation. At this time, the first position of the turntable 3 is the fastener part. The turntable 3 is rotated to the second position, and the toothless end part is placed by the pneumatic gripper 30. Then the sealing ring part is placed by the pneumatic gripper 30. The toothed end part and the toothless end part are transported to the end of the second conveyor belt 6. At the third position, the pneumatic gripper 30 places the toothed end part at the third position. Then the turntable 3 is rotated to the fifth position, and the toothed end part is screwed into the fastener part by the rotary cylinder 27. Another sealing ring part is placed at the sixth position by the pneumatic gripper 30. The pipe joint is pushed into the discharge port 33 by the discharge lever 32.

[0028] The output end of the rotary cylinder 27 is conical, which presses the toothed end part during the descent and simultaneously positions the toothed end part. After the conical part of the rotary cylinder 27 screws the part in, the rebound force of the spring 26 disengages the part, preventing the product from getting stuck at the output end of the rotary cylinder 27.

[0029] The turbine reduction motor 8 directly drives the turntable 3. The bottom surface of the turntable 3 is provided with a protrusion, and the edge is provided with a chamfered slope. Two columnar protrusions are provided around the contact of the fastener parts to restrict the rotation of the fastener parts. The bottom surface of the turntable 3 is positioned with the retaining ring 31 to keep the fastener parts in an upright position and convey them to the working position. At the seventh working position, the finished product is pushed off by the material dropping lever 32.

[0030] In the screw-in module 4, the screw-in bracket 18 supports the first slide rail 20. The extension and retraction of the first cylinder 19 drives the first slider 21 to move horizontally on the first slide rail 20. The movement of the first slider 21 drives the second slide rail 23 to move. The extension and retraction of the second cylinder 22 realizes the back-and-forth movement of the second slider 24, thereby realizing the lifting and lowering of the first fixed frame 25, which in turn drives the rotary cylinder 27 to move up and down, and the screw-in operation is performed by the rotary cylinder 27.

[0031] The pneumatic gripper 30 uses a four-jaw gripper, enabling precise positioning and accurate gripping. During the gripping process, the sealing ring part can be unfolded for easy installation. The first conveyor belt 5 and the second conveyor belt 6 respectively transmit parts through the baffle 17, while the fixed shaft 16 provides fixed support for the first conveyor belt 5 and the second conveyor belt 6. The baffle 17 allows for the simultaneous transport of two rows of parts, reducing machine costs and energy consumption. The front end of the baffle 17 is inclined to guide the parts into the guide plate, and the end of the baffle 17 is lower than the height of the parts to prevent interference between the pneumatic grippers 30 on both sides during operation, thus affecting the normal operation of the corresponding pneumatic grippers 30. The first sealing ring gripping module 12 forms a 15° angle with the first conveyor belt 5, the toothless end gripping module 13 forms a 75° angle with the first conveyor belt 5, the toothed end gripping module 14 forms a 90° angle with the second conveyor belt 6, and the second machine support 10 forms a 45° angle with the first conveyor belt 5.

[0032] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
