[0024] See also Figure 1-6 , the utility model provides a technical solution:

[0025] A welding and assembly fixture for an intake manifold of an oxygen concentrator comprises a welding workbench 1 and an upper die base mechanism. First sliding guide rails 2 are laterally arranged at the front and rear ends of the top of the welding workbench 1. A first sliding inner cavity 13 is provided at the top of the two first sliding guide rails 2. A sliding rod 10 is slidably connected to the first sliding inner cavity 13. Threaded holes 11 are provided at the centers of both sides of the sliding rod 10. A first screw rod 12 is connected to the inside of the threaded hole 11 by a thread. The two ends of the first screw rod 12 are respectively connected to different side surfaces of the first sliding inner cavity 13. A connecting plate 5 is provided on the top of the sliding rod 10. The tops of the two connecting plates 5 are respectively connected to different ends of the bottom of the lower die base mechanism 3. An upper die base mechanism 4 is provided above the lower die base mechanism 3. A connecting block 24 is provided on the back, and a clamping block 23 is provided on the back of the connecting block 24. A lifting mechanism 15 is provided on the top and back of the welding workbench 1 in the vertical direction. A lifting mechanism inner cavity 16 is opened on the top of the front of the lifting mechanism 15. A second screw rod 17 is provided at the top and bottom center of the lifting mechanism inner cavity 16. A lifting block 20 is provided on the surface of the second screw rod 17. A limiting rod 19 is provided between the top and bottom ends of the lifting block 20. The top and bottom of the limiting rod 19 are respectively connected to the top and bottom of the lifting mechanism inner cavity 16. A second sliding guide rail 21 is provided on the front of the lifting block 20. A second sliding inner cavity 22 is opened on the front of the second sliding guide rail 21. The second sliding inner cavity 22 is slidably connected with a clamping block 23.

[0026] Furthermore, a lower mold 6 is provided inside the lower mold base mechanism 3 , and the size of the lower mold 6 matches the internal size of the lower mold base mechanism 3 .

[0027] Furthermore, a bottom through hole 7 is opened at the bottom center of the lower die base mechanism 3 , and an impact plate 9 is matched and connected to the bottom through hole 7 .

[0028] Furthermore, the bottom center of the impact plate 9 is connected to the bottom telescopic end of the telescopic cylinder 8 , and the bottom of the telescopic cylinder 8 is fixedly connected to the top of the welding workbench 1 .

[0029] Furthermore, a reciprocating motor 14 is fixedly connected to the center of one side of one of the first sliding guide rails 2 , and the bottom output end of the reciprocating motor 14 is connected to one end of the first screw rod 12 .

[0030] Furthermore, a lifting motor 18 is fixedly connected to the top center of the lifting mechanism 15 , and a bottom output end of the lifting motor 18 is connected to the top of the second screw rod 17 .

[0031] Working principle: It should be noted that the upper mold inside the upper mold base mechanism 4 is connected to the inside of the upper mold base mechanism 4, and the upper mold base mechanism 4 can move in the vertical direction. Specifically, when the upper mold base mechanism 4 needs to be moved, the lifting motor 18 is started first. The start of the lifting motor 18 will cause the second screw rod 17 to rotate, and the rotation of the second screw rod 17 will cause the lifting block 20 to move in the vertical direction. The movement of the lifting block 20 will cause the second sliding guide rail 21 to move, and the movement of the second sliding guide rail 21 will cause the card block 23 to move, and the movement of the card block 23 will cause the upper mold base mechanism 4 to move.

[0032] When it is used specifically, the staff first places the lower intake manifold on the lower mold, and then places the upper intake manifold on the upper mold, and then welds it. In the process of moving the upper mold base mechanism 4 to the top of the lower mold base mechanism 3, the staff can use tools to ensure that the upper intake manifold will not fall out. During welding, it is necessary to start the repetitive motor 14. The start of the repetitive motor 14 will rotate the screw rod 12, and the rotation of the screw rod 12 will cause the sliding rod 10 to reciprocate. The reciprocating motion of the sliding rod 10 will cause the connecting plate 5 to reciprocate, and the reciprocating motion of the connecting plate 5 will cause the lower mold base Mechanism 4 performs reciprocating motion. At the beginning, the upper mold is not welded to the lower mold. After a while, the welding surface will generate heat due to friction, causing the plastic at a certain location to melt. Then the lower mold base mechanism 3 will move with the upper mold base mechanism 4. Specifically, the clamping block 23 will slide along the second sliding cavity 22. After a period of friction, the welding of the upper and lower intake manifolds will be completed. When the welding is completed, when the finished product needs to be taken out, the upper mold base mechanism 3 will be moved upward first, and then the telescopic cylinder 8 will be started to impact the impact plate 9 upward, causing the lower mold to vibrate to a certain extent, which is convenient for the separation of the finished product and has certain practicality.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
