[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1 The utility model provides a technical solution: an elliptical air duct weld grinding device.

[0023] Among them, a fixing frame 2 is arranged at the middle and right position of the top of the transmission platform 1, a grinding frame 3 is arranged on the left side of the fixing frame 2, arc surfaces are opened at the centers of the two fixing frames 2, a mounting groove 201 is opened at the center of the arc surface, a plurality of rollers 202 are installed inside the mounting groove 201, a bottom slider 203 is fixedly connected to the bottom of the fixing frame 2, a sliding cavity 101 is opened under the fixing frame 2 of the transmission platform 1, the bottom slider 203 is arranged in the sliding cavity 101, a pushing plate 4 is arranged on the right side of the top of the transmission platform 1, an adjusting window 401 is opened through the center position of the pushing plate 4, a clamping block 403 is installed in the adjusting window 401, a hydraulic rod 405 is arranged on the right side of the pushing plate 4, and a hydraulic cylinder 404 is arranged on the right side of the hydraulic rod 405.

[0024] In this embodiment, the air duct 5 passes through two symmetrical fixing frames 2, and then passes through the grinding frame 3 on the left side, and finally the opening is attached to the push plate 4. There are two symmetrical clamping blocks 403 on the adjusting window 401 of the push plate 4, and the front end is provided with a cushion center and a circular arc gap. The air duct 5 is inserted into the two gaps to fix the front section of the air duct 5, and the bottom is closed by two fixing frames 2. The circular arc of the fixing frame 2 fits the wall of the air duct 5, and the roller 202 in the mounting groove 201 also fits the wall of the air duct, and rotates The air duct 5 ensures that the welding position is aligned with the grinding head 301 on the grinding frame 3. At this time, the power supply 304 is started, and the current is input into the controller 302 through the connecting line 303 to start the rotation of the grinding head 301. Then the hydraulic cylinder 404 is started, and the hydraulic rod 405 extends from the hydraulic cylinder 404, pushing the pushing plate 4 to the right and pushing the air duct 5. The roller 202 that fits the wall of the air duct 5 rotates to assist the air duct 5 to move to the right and ensure the stability of the air duct 5.

[0031] There are two fixing frames 2 and two grinding frames 3 arranged on the top of the transmission platform 1 .

[0032] In this embodiment, the number of the fixing frames 2 and the grinding frames 3 is increased to lengthen the transmission platform 1 to adapt to the grinding of a longer air duct 5 .

[0033] Working principle: the air duct 5 passes through two symmetrical fixing frames 2, and then passes through the grinding frame 3 on the left side. One end of the air duct is attached to the pushing plate 4, and the positions of the two clamping blocks 403 are adjusted. The opening is inserted into the clamping block 403 to fix the air duct 5, and it is ensured that the weld position of the air duct 5 is at the top and aligned with the grinding head 301. Then, the adjusting threaded rod 102 is rotated to close the two fixing frames 2 to fix the air duct 5, and the power supply 304 is started to make the grinding head 301 work. Then, the hydraulic cylinder 404 is started again, and the pushing plate 4 is pushed forward by extending the hydraulic rod 405. The roller 202 on the fixing frame 2 rotates, and the grinding head 301 grinds the air duct 5.
