Description

Technical field:

[0036] Working principle: The present invention is a pressing mechanism on an automatic assembly machine for air pipe joints. The pressing mechanism is as shown in Figure 2 、 3 . The main technology is located on the feeding rack 7 and the material clamping seat 8. The feeding rack 7 moves on the longitudinal guide rail 5 through the feeding cylinder 6. When the feeding rack 7 moves to the rear end of the longitudinal guide rail 5, the feeding rack 7 is above the material trough. The release ring in the material trough can be pushed into the material clamping seat 8 by the lifting platform driven by the cylinder. The material clamping seat 8 can clamp the release ring; when the feeding rack 7 moves to the front end of the longitudinal guide rail 5, the pressing post 71 on the feeding rack 7 is directly below the pressing head 11. By starting the pressing cylinder 10, the pressing head 11 moves downward to contact the feeding rack 7 and drives the pressing post 71 to move downward, thereby pressing the release ring on the material clamping seat 8 into the joint body at the pressing station. When the pressing cylinder 10 resets, the feeding rack 7 resets based on the acting force of the return spring 78. At the same time, the material clamping seat 8 disengages from the release ring on the joint body;

[0037] Among them, the material clamping seat 8 positions the release ring by using the outer seat body 81 and limits the release ring by using the rubber sealing ring 82. When the release ring is pushed into the material clamping seat 8, the retaining ring on the upper part of the release ring can press the rubber sealing ring 82 to deform, enabling the retaining ring on the upper part of the release ring to cross over the rubber sealing ring 82. Then the rubber sealing ring 82 resets to support the lower end face of the retaining ring on the upper part of the release ring, preventing it from falling when the material clamping seat 8 moves;

[0038] After the release ring is press-fitted into the joint body, since the joint body is clamped and fixed on the work station, the release ring can force the rubber sealing ring 82 to deform and separate from the release ring. At the same time, a central positioning post 814 is provided on the material clamping seat 8, which can ensure the central positioning and verticality of the release ring, facilitate the release ring to be aligned with the joint body and vertically press into the joint body.

[0039] The described embodiments are used to illustrate the present invention by way of example, rather than to limit the present invention. Any person skilled in the art can modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of the rights protection of the present invention should be as listed in the claims of the present invention.
