The moving end of the translation mechanism 30 is provided with a translation slide 31, and the translation slide 31 is provided with a propping mechanism 32. The moving end of the propping mechanism 32 is provided with a plurality of claws 33, and the propping mechanism 32 is used to drive the plurality of claws 33 to open or close. The plurality of claws 33 are aligned with the pipe head of the pipe fitting 100, and the outer sides of the plurality of claws 33 are used to cover the sealing ring 101. A material stripping mechanism 34 is fixed on the translation slide 31, and the moving end of the material stripping mechanism 34 is provided with a material stripping plate 35, and the material stripping plate 35 is arranged on the front side of the propping mechanism 32. A through hole 350 is provided on the material stripping plate 35, and the plurality of claws 33 all pass through the through hole 350, and the material stripping mechanism 34 is used to drive the material stripping plate 35 to move forward and backward.

[0022] In the above structure, the machine 1 is provided with a jig 2 and an assembly component 3, and the number of the assembly components 3 corresponds to the number of the pipe heads of the pipe fitting 100. During assembly, the pipe fitting 100 is first loaded on the jig 2, and the opening mechanism 32 is controlled to move and drive the multiple claws 33 to close. When the operator sets the sealing ring on the outside of the multiple claws 33, the opening mechanism 32 is controlled to move and drive the multiple claws 33 to open the sealing ring. Then, the translation mechanism 30 drives the translation slide 31 to move forward and translate until the multiple claws 33 are aligned. And it abuts against the tube head of the pipe fitting 100, and then controls the movement of the material return mechanism 34, and the material return mechanism 34 drives the material return plate 35 to move forward, and the sealing rings sleeved on the multiple support claws 33 are pushed to the tube head of the pipe fitting 100 by means of the material return plate 35, thereby completing the process of sleeve sealing rings on the pipe fitting. Compared with the prior art, the utility model better realizes the automatic assembly of sealing rings, can avoid damage to the sealing rings during the assembly process, can effectively improve the assembly quality, and at the same time does not require the staff to perform too much operation, saving time and effort and having a high assembly efficiency.

[0023] In this example, see Figure 1 and Figure 2 The pipe fitting 100 has three pipe heads, and the machine 1 is provided with three assembly components 3, and the assembly components 3 correspond to the pipe heads one by one. Based on the above structure, the present embodiment can assemble sealing rings for the three pipe heads of the pipe fitting 100 at the same time. Compared with a single assembly method, the present invention greatly shortens the working time and thus improves the assembly efficiency.

[0024] In order to reliably fix the translation mechanism 30, in this embodiment, see Figure 3 A bottom plate 36 is fixed to the bottom of the translation mechanism 30, and the bottom plate 36 is fixedly connected to the machine platform 1. Specifically, the translation mechanism 30 and the material-removing mechanism 34 are both linear cylinders.

[0025] Combination Figure 3 and Figure 4 As shown, in this embodiment, the spreading mechanism 32 is a circular three-finger pneumatic clamp, and the spreading mechanism 32 includes three moving fingers 320, which are evenly distributed on the end surface of the spreading mechanism 32 along the circumferential direction, and a spreading claw 33 is fixed on each moving finger 320.

[0027] In the above structure, when the spreading mechanism 32 is in action, the three moving fingers 320 can be driven to move away or approach synchronously, thereby driving the three supporting claws 33 to open or close, that is, when the sealing ring is loaded, the three supporting claws 33 are controlled to close, and after the sealing ring is loaded, the three supporting claws 33 are controlled to open.

[0028] As a preferred embodiment, two material stripping mechanisms 34 are fixed on the translation slide 31, and the two material stripping mechanisms 34 are symmetrically arranged on both sides of the opening mechanism 32. The material stripping plate 35 is U-shaped, and the two ends of the material stripping plate 35 are respectively fixedly connected to the moving ends of the two material stripping mechanisms 34. Among them, this embodiment preferably adopts the method of two material stripping mechanisms 34 synchronously driving one material stripping plate 35 to move forward and backward, which can ensure the mechanical balance of the two ends of the material stripping plate 35, so that the material stripping plate 35 moves forward and backward in a straight line, thereby improving the movement accuracy of the push sealing ring.

[0029] On this basis, see Figure 4 The inner ring end of the through hole 350 is provided with three slide grooves 351 , and the outer arc surface parts 330 of the three support claws 33 pass through the three slide grooves 351 respectively, and the outer arc surface parts 330 are slidably matched with the slide grooves 351 .
