[0015] Step 2: When the inclination angle of the first support frame changes, the height of the second support frame changes, and the second support frame drives the first movable plate, the fixed sleeve and the movable ring to move downward.

[0020] Step 7: When the first tooth plate is no longer located on one side of the first gear, return to step 4, and the staff removes the welded pick until the pick welding is completed.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) Drive several first support frames to rotate synchronously through a synchronous meshing rotation mechanism to change the inclination angle of the first connecting shaft, and then adjust the inclination angle of the pick holder so that the pick holder is at a preset inclination angle. When the inclination angle of the first support frame changes, the height of the second support frame changes, and the second support frame drives the first movable plate, the fixed sleeve and the movable ring to move downward. At the same time, the second support frame drives the first movable plate to slide in the fixed sleeve. The height of the third connecting shaft changes, and the third connecting shaft still remains perpendicular to the horizontal plane. After completing the adjustment of the inclination angle of the pick holder, the staff fixes the assembled tooth body and the alloy head on the pick holder, drives the first rotating shaft to rotate through the intermittent driving structure, and the first rotating shaft drives the support platform and the first support frame so that the tooth body and the alloy head installed on the pick holder move to one side of the welding mechanism, drives the support plate to move up through the first electric telescopic rod, so that the first tooth plate moves to one side of one of the first gears, drives the third support part and the first tooth plate to move relative to the support plate through the second electric telescopic rod, and the first The toothed plate drives the first gear and the third connecting shaft to rotate, the third connecting shaft drives the third bevel gear to rotate, the third bevel gear drives the second bevel gear and the second connecting shaft to rotate, the second bevel gear drives the first connecting shaft and the pick holder to rotate through the first bevel gear, and the welding mechanism welds the rotating tooth body and the alloy head. During the welding process of the welding mechanism, the staff installs the assembled tooth body and the alloy head on the next pick holder. When the tooth body and the alloy head on one side of the welding mechanism are welded, the first electric telescopic rod drives the support plate and the first toothed plate to move downward to avoid the first toothed plate interfering with the first gear to follow the first rotating shaft to rotate, and the first rotating shaft is driven to rotate through the intermittent driving structure, so that the next assembled tooth body and the alloy head are moved to one side of the welding mechanism, and the next welding work can be directly carried out. The staff removes the welded pick and installs the assembled tooth body and the alloy head on the next pick holder at the same time, so as to adjust the inclination angle of the tooth body and the alloy to be welded according to actual needs, and does not need the welding mechanism to wait for the installation of the tooth body and the alloy head and the removal of the pick, thereby increasing work efficiency;

[0023] (2) The third electric telescopic rod drives the movable seat and the adjustment plate to move in the vertical direction relative to the support platform, and the adjustment plate drives the second toothed plate to move in the vertical direction. The second toothed plate drives the second gear and the second rotating shaft to rotate, so that the inclination angles of several first support frames are changed synchronously, which is convenient for adjusting the inclination angle of the first support frame. The staff drives the two adjacent second nuts to rotate so that the two adjacent second nuts no longer clamp the adjustment plate, thereby releasing the limitation on the position of the adjustment plate. The staff drives the adjustment plate and the second toothed plate to move in the vertical direction, and at the same time, the guide block slides in the guide groove to change the height of the second toothed plate, and then drives the second gear and the second rotating shaft to rotate through the second toothed plate, so as to change the inclination angle of a single first support frame, ensuring that the initial state of each first support frame maintains the same inclination angle. When the height of the adjustment plate is adjusted, the staff drives the two adjacent second nuts to rotate so that the two adjacent second nuts clamp the adjustment plate, so that the adjustment plate is fixed relative to the movable seat;

[0024] (3) The staff places the ends of the assembled tooth body and the alloy head in the receiving groove, pushes the ends of the assembled tooth body and the alloy head to the end of the movable column away from the fixed disk and moves into the through hole, so that the fixed disk moves away from the fixed block, and the tension spring is in a tensioned state. The tension spring applies a pulling force to the fixed disk and the movable column, so that the plurality of movable columns clamp the ends of the assembled tooth body and the alloy head, so that the assembled tooth body and the alloy head are fixed relative to the fixed block;

[0025] (4) The second sprocket is driven to rotate by a motor, and the second sprocket drives the first sprocket and the first rotating shaft to rotate through a chain, so that the support platform and the first support frame can rotate relative to the base, so that the pick holder can move to one side of the welding mechanism. The staff drives the two first nuts to rotate so that the two first nuts no longer clamp the second movable plate, thereby releasing the limitation on the position of the second movable plate. The staff drives the second movable plate to slide relative to the base and the first screw rod, so that the welding mechanism moves horizontally and changes the position of the welding mechanism. After the position of the welding mechanism is adjusted, the staff drives the two first nuts to rotate, and the two first nuts clamp the second movable plate, so that the second movable plate and the welding mechanism are fixed relative to the first screw rod and the base. The fourth electric telescopic rod is used to drive the mounting seat to move in the vertical direction, so that the initial height of the welding mechanism can be adjusted, which is convenient for adjusting the initial position of the welding mechanism according to actual needs.
