[0032] Furthermore, the fixing seat 6 and the supporting seat 4 are fixed by bolts, and the supporting seat 4 is slidably connected to the supporting rod 3. The fixing seat 6 and the supporting seat 4 can be used to fix the round steel, and the supporting rod 3 can be used to limit the supporting seat 4 to maintain horizontal movement;

[0033] Furthermore, the support rod 3 and the bidirectional screw rod 5 are arranged parallel to each other, the left and right sections of the bidirectional screw rod 5 have opposite thread distribution directions, and the sections of the bidirectional screw rod 5 with opposite thread directions are both connected to the support seat 4. By rotating the bidirectional screw rod 5, the symmetrically distributed support seats 4 are driven to move in the opposite direction at the same time to dock the round steel.

[0034] A mounting frame 8 is installed above the workbench 1, a hydraulic rod 9 is installed above the mounting frame 8, a welding head 10 is connected to the output end of the hydraulic rod 9, a protective cover 11 is installed on the outside of the welding head 10, a main moving rod 12 is connected above the welding head 10, and a first gear block 13 is connected to the outside of the main moving rod 12; a rotating shaft 14 is rotatably connected to the top of the mounting frame 8, and a second gear 15 is keyed to the end of the rotating shaft 14, a secondary moving rod 16 passes through the upper end of the mounting frame 8, and a second gear block 17 is connected to the side of the secondary moving rod 16, and a support frame 18 is installed at the lower end of the secondary moving rod 16, a motor 19 is installed on the support frame 18, and a grinding disc 20 is connected to the output end of the motor 19;

[0035] Furthermore, the main moving rod 12 and the auxiliary moving rod 16 are arranged parallel to each other, and the first tooth block 13 and the second tooth block 17 are arranged at equal intervals at the connection between the main moving rod 12 and the auxiliary moving rod 16 and the second gear 15, respectively. The first tooth block 13 and the second tooth block 17 are meshed with the second gear 15, and the transmission of the second gear 15 can be used to realize the linkage of the main moving rod 12 and the auxiliary moving rod 16, and drive the main moving rod 12 and the auxiliary moving rod 16 to move in opposite directions at the same time;

[0036] Furthermore, the secondary moving rod 16 and the main moving rod 12 both penetrate the upper end surface of the mounting frame 8, and the secondary moving rod 16 and the main moving rod 12 and the mounting frame 8 form a sliding structure, which allows the main moving rod 12 and the secondary moving rod 16 to move smoothly and adjust the positions of the welding head 10 and the grinding disc 20;

[0037] Furthermore, the grinding disc 20 is symmetrically arranged about the longitudinal center line of the welding head 10, and the lowest point of the welding head 10 is higher than the lowest point of the protective cover 11, so that the grinding disc 20 limits the placement position of the round steel and grinds its welding end, while the protective cover 11 can shield and protect the welding area;

[0038] The rear side of the protective cover 11 is connected to a connecting rod 21, the rear side surface of the connecting rod 21 is connected to a third tooth block 22, and the left and right sides of the protective cover 11 are both provided with through grooves 23;

[0039] Furthermore, the third tooth blocks 22 are evenly spaced and distributed at the connection between the connecting rod 21 and the first gear 7. The third tooth blocks 22 mesh with the first gear 7. The transmission of the first gear 7 is used to control the rotation of the bidirectional screw rod 5 when the connecting rod 21 moves.

[0040] Furthermore, the through slot 23 passes through the lower end of the protective cover 11, and the through slot 23 is an "n"-shaped structure, so that the protective cover 11 can move downward smoothly, and the round steel can be prevented from blocking the protective cover 11;

[0041] Specifically, the round steel is placed on the supporting wheel 2 and the supporting seat 4, and the supporting wheel 2 and the supporting seat 4 are used to support it, and the welding end of the round steel is fitted with the grinding disc 20, and the grinding disc 20 limits the placement position of the round steel, and then the fixing seat 6 can be driven to rotate, and one end of the fixing seat 6 is rotatably connected to the supporting seat 4, and the fixing seat 6 and the supporting seat 4 are enclosed together, and the other end of the fixing seat 6 is fixed to the supporting seat 4 by bolts, and the fixing seat 6 and the supporting seat 4 are locked with bolts, so that the round steel can be fixed, and the round steel is locked between the fixing seat 6 and the supporting seat 4. According to the above steps, the two round steels are fixed symmetrically respectively, and then the motor 19 can be powered on, and the motor 19 controls the grinding disc 20 connected to the output end to rotate, and the grinding disc 20 grinds the end of the round steel, burrs the welding end of the round steel, and grinds off the attached impurities;

[0042] The hydraulic rod 9 is opened to push the welding head 10 to move downward. At this time, the protective cover 11 installed on the outside of the welding head 10 moves downward synchronously. At the same time, the main moving rod 12 installed above the welding head 10 moves downward. The first tooth block 13 connected to the side of the main moving rod 12 is meshed with the second gear 15, so the second gear 15 can be driven to rotate. The second gear 15 is meshed with the second tooth block 17, and the second tooth block 17 is installed on the side of the auxiliary moving rod 16, so the auxiliary moving rod 16 can be controlled to move upward. The transmission of the meshed first tooth block 13, the second gear 15 and the second tooth block 17 can realize the linkage between the main moving rod 12 and the auxiliary moving rod 16, and the auxiliary moving rod 16 is synchronized. The control support frame 18 moves up, thereby driving the grinding disc 20 to move up. When the grinding disc 20 moves up to the point where it is about to disengage from the round steel, the third tooth block 22 on the connecting rod 21 installed on the rear side of the protective cover 11 meshes with the first gear 7, driving the bidirectional screw rod 5 to rotate. The bidirectional screw rod 5 controls the relative movement of the support seat 4 connected with the outer thread. The support seat 4 slides on the support rod 3 at the same time, and the support seat 4 is limited by the support rod 3 to ensure the horizontal movement of the support seat 4, thereby controlling the relative movement of the round steel locked by the support seat 4 and the fixed seat 6, and applying force to make the round steel continue to fit the lower end position of the grinding disc 20, and the end is polished and cleaned. The grinding disc 20 When it moves to be separated from the round steel, the round steel continues to move relatively until the round steel is butted. At this time, the third tooth block 22 moves down to be separated from the first gear 7, and the protective cover 11 moves down with the welding head 10, and the protective cover 11 is gradually set in the welding area. The round steel passes through the through groove 23 opened on the side of the protective cover 11 to avoid blocking the downward movement of the protective cover 11, and the welding head 10 gradually moves down to the butt end of the round steel to release, control the welding head 10 to work, and weld the round steel. After welding is completed, the bolts on the fixing seat 6 can be removed, and the fixing seat 6 can be driven to reverse and open to release the fixation of the round steel, and then the hydraulic rod 9 is controlled to drive the welding head 10 to move up , thereby controlling the protective cover 11 to move up, and moving the protective cover 11 to a position above the round steel, the round steel can be removed. At the same time, due to the upward movement of the protective cover 11, the connecting rod 21 can be controlled to move up, and the meshing of the meshing third tooth block 22 and the first gear 7 can drive the bidirectional screw rod 5 to rotate in the opposite direction, thereby driving the support seats 4 to move away from each other and reset, and continue to control the welding head 10 to move up, and use the transmission of the first tooth block 13, the second gear 15 and the second tooth block 17 to control the grinding disc 20 to move down and reset, which is convenient for the subsequent welding processing of the round steel.
