Anti-slip grooves 17 are opened on the inner wall of the rubber pad 16. After the upper fixture seat 5 and the lower fixture seat 13 are separated, directly move the valve core into the fixing holes 15. Then start the second electric push rod 12 again, so that the second electric push rod 12 pulls the lower fixture seat 13 and makes the rubber pads 16 on the two fixture seats contact the outside of the valve core.

[0032] The working principle of the present utility model is as follows: When in use, start the second electric push rod 12, so that the second electric push rod 12 pushes the lower fixture seat 13 downward, and then move the valve core into the fixing hole 15. Start the second electric push rod 12 again, so that the upper fixture seat 5 and the lower fixture seat 13 are closed together. At the same time, the rubber pad 16 inside the fixing hole 15 contacts the valve core and fixes the valve core inside the fixing hole 15. When adjusting the welding angle of the valve core, start the motor 6, so that the motor 6 drives the valve core fixed inside the two fixture seats to rotate left and right through the first electric push rod 2, the connecting frame 3 and the connecting plate 4. Then start the double-headed motor 9, so that the double-headed motor 9 drives the connecting plate 4 to rotate up and down through the rotating shaft 8, so that the connecting plate 4 drives the valve core fixed by the two fixture seats to rotate up and down. The cooperation of the motor 6 and the double-headed motor 9 enables the fixed valve core to rotate to a suitable angle for welding. At the same time, the height of the fixed valve core can be adjusted through the first electric push rod 2.

[0033] Compared with the prior art, the present utility model has the following beneficial effects over the prior art:

[0034] 1. When welding the valve core, after the upper fixture seat 5 and the lower fixture seat 13 cooperate to fix the valve core, at this time, the motor 6 drives the first electric push rod 2, so that the first electric push rod 2 drives the two fixture seats to rotate left and right through the connecting frame 3 and the connecting plate 4. When starting the double-headed motor 9, the double-headed motor 9 drives the connecting plate 4 through the rotating shaft 8, so that the connecting plate 4 drives the two fixture seats to rotate up and down. The cooperation of the motor 6 and the double-headed motor 9 enables the valve core fixed inside the fixture seat to be adjusted in angle in multiple directions, improving the welding effect when welding the valve core.

[0035] 2. When fixing the valve core, start the second electric push rod 12, and the second electric push rod 12 pushes the lower fixture seat 13, so that the lower fixture seat 13 is separated from the upper fixture seat 5. Then move the valve core into the fixing hole 15. Push the second electric push rod 12 again, so that the upper fixture seat 5 and the lower fixture seat 13 cooperate to fix the valve core. When adjusting the height of the fixed valve core, directly drive the first electric push rod 2.
