A fourth connecting rod 15 is connected to the first positioning groove of the fourth sliding block 11 and the first sliding block 8 through a rotating shaft. A protruding plate 29 is fixedly arranged at the bottom of the fourth sliding block 11. Working A cylinder 30 is provided inside the table 1 and below the connecting rod mechanism. The output end of the cylinder 30 is fixedly connected to the extension plate 29. The extension plate 29 is driven by the cylinder 30 to move toward the end of the workbench 1. During the process of the fourth sliding block 11 moving toward the end of the workbench 1, the third connecting rod 14 and the fourth connecting rod 15 will respectively drive the second sliding block 9 and the first sliding block 8 to move toward the middle of the workbench 1. At the same time, the second sliding block 9 and the first sliding block 8 will respectively drive the third sliding block 10 to move toward the end of the workbench 1 through the second connecting rod 13 and the first connecting rod 12. The cylinder 30 drives the extension plate 29 to move toward the middle of the workbench 1. During the process of the fourth sliding block 11 moving toward the middle of the workbench 1, the third connecting rod 14 and the fourth connecting rod 15 will respectively drive the second sliding block 9 and the first sliding block 8 to move toward the end of the workbench 1.

When the second sliding block 9 and the first sliding block 8 move toward the middle of the workbench 1, the extrusion heads 16 at the ends of the second extrusion block 5 and the first extrusion block 4 will squeeze the two ends of the three-way valve 2 to fix the three-way valve 2.

[0027] The material receiving mechanism 6 includes a sliding frame 17, and a sliding bar is provided on the surface of the workbench 1. The bottom of the sliding frame 17 slides on the surface of the sliding bar. A material receiving plate 18 is installed inside the sliding frame 17 by bolts. The end of the material receiving plate 18 close to the support plate 3 protrudes out of the sliding frame 17, and the horizontal height of the material receiving plate 18 is higher than the horizontal height of the support plate 3. When the third sliding block 10 and the fourth sliding block 11 move toward the middle of the workbench 1, the sliding frame 17 and the material receiving plate 18 will move toward the direction of the support plate 3, so as to facilitate the storage of the three-way valve 2 after welding.

[0028] The pushing mechanism 7 includes a pushing block, which is slidably arranged in front of the three-way valve 2. The horizontal height of the pushing block is consistent with the horizontal height of the receiving plate 18. A pushing plate 19 is installed on the top of the pushing block by bolts. When the third sliding block 10 and the fourth sliding block 11 move toward the middle of the workbench 1, the pushing plate 19 can push the welded three-way valve 2 to the surface of the receiving plate 18, so that the three-way valve 2 can be quickly disassembled.

[0029] The supporting mechanism 27 includes a side frame 20, which is fixedly mounted on the side of the support plate 3. An opening 24 is provided at one end of the side frame 20 close to the material receiving mechanism 6. A rectangular block 21 is slidably arranged inside the side frame 20. A guide bar is arranged on the side of the support plate 3 and located inside the side frame 20. The surface of the rectangular block 21 slides on the surface of the guide bar to ensure the stability of the rectangular block 21 moving inside the side frame 20. A spring 23 is arranged at one end of the rectangular block 21 away from the opening 24. A rack 22 is arranged on the top of the rectangular block 21. A gear 25 is rotatably installed on the side of the support plate 3 and above the guide bar. The gear 25 meshes with the rack 22. A supporting frame 26 is arranged on the top of the gear 25.

The end of the sliding frame 17 close to the support plate 3 is opposite to the It is said that two insertion plates 28 are installed, and the two insertion plates 28 correspond to the two openings 24 respectively. Since the end of the insertion plate 28 is closer to the support plate 3 than the end of the receiving plate 18, when the third sliding block 10 and the fourth sliding block 11 move to the middle of the workbench 1, the insertion plate 28 can be inserted into the opening 24 first, and the rectangular block 21 is pushed toward the inner side of the side frame 20. At the same time, the gear 25 rotates, and the top of the support frame 26 will move toward the direction of the receiving mechanism 6. The three-way valve 2 will be in a tilted state. Under normal conditions, the elastic force of the spring 23 will push the rectangular block 21 toward the opening 24. When the top of the rectangular block 21 close to one end of the opening 24 is close to the surface of the side frame 20, the position of the rectangular block 21 is positioned, the gear 25 is stationary, and the support frame 26 is in an upright state.

The stepper motor drives the workbench 1 to rotate, and the welding gun can weld the three-way valve 2 360 degrees.

[0031] Working principle: First, the cylinder 30 controls the extension plate 29 to move, so that the slide column slides to the middle of the guide groove. At this time, the elastic force of the spring 23 will push the rectangular block 21 to the opening 24. When the top of the rectangular block 21 close to the opening 24 is close to the surface of the side frame 20, the position of the rectangular block 21 is positioned, the gear 25 is stationary, and the support frame 26 is in an upright state. The staff then places the three-way valve 2 on the surface of the support plate 3. The two support frames 26 pre-position the three-way valve 2. Then the cylinder 30 drives the extension plate 29 to the workbench 1. The third connecting rod 14 and the fourth connecting rod 15 will respectively drive the second sliding block 9 and the first sliding block 8 to move toward the middle of the workbench 1 during the process of the fourth sliding block 11 moving toward the end of the workbench 1. At the same time, the second sliding block 9 and the first sliding block 8 will respectively drive the third sliding block 10 to move toward the end of the workbench 1 through the second connecting rod 13 and the first connecting rod 12. The extrusion heads 16 at the ends of the second extrusion block 5 and the first extrusion block 4 will squeeze the two ends of the three-way valve 2 to fix the three-way valve 2, and then drive the workbench 1 through the stepper motor. The table 1 rotates, and the welding gun can weld the three-way valve 2 at 360 degrees. In the next step, the cylinder 30 drives the extended plate 29 to move toward the middle of the workbench 1. During the process of the fourth sliding block 11 moving toward the middle of the workbench 1, the third connecting rod 14 and the fourth connecting rod 15 will respectively drive the second sliding block 9 and the first sliding block 8 to move toward the end of the workbench 1. At the same time, the second sliding block 9 and the first sliding block 8 will respectively drive the third sliding block 10 to move toward the middle of the workbench 1 through the second connecting rod 13 and the first connecting rod 12. The connecting rod mechanism can simultaneously squeeze the first The positions of the first extrusion block 4, the second extrusion block 5, the material receiving mechanism 6 and the pushing mechanism 7 are controlled. At this time, the first extrusion block 4 and the second extrusion block 5 have no extrusion effect on the three-way valve 2, and the insertion plate 28 can be inserted into the opening 24 to push the rectangular block 21 toward the inside of the side frame 20. At the same time, the gear 25 rotates, and the top of the support frame 26 moves toward the direction of the material receiving mechanism 6. The three-way valve 2 will be in an inclined state, so that the pushing plate 19 can push the welded three-way valve 2 to the surface of the material receiving plate 18, and the three-way valve 2 can be quickly disassembled.
