The welding slag and smoke generated during welding can be sucked away by the suction component 7, so as to improve the safety and hygiene of the staff in welding.

[0025] like Figure 1-4 As shown, the limiting assembly 6 includes a stabilizing rod 61, a rotating part 62 is arranged on one side of the bottom surface of the stabilizing rod 61, and the side wall of the rotating part 62 is connected to the side wall of the base 1; a mounting hole 63 is opened on one side of the middle position of the top of the stabilizing rod 61, and an electric push rod 64 is arranged in the inner cavity of the mounting hole 63, a pressing frame 65 is arranged on the bottom surface of the electric push rod 64, and an anti-slip pad 66 is arranged on the bottom surface of the pressing frame 65, and the rotating part 62 includes a positioning column 621 arranged on the side wall of the base 1, and an axial hole 622 is opened at the top of the positioning column 621, and a shaft rod 623 is inserted in the inner cavity of the shaft hole 622, and the top of the shaft rod 623 is connected to the side wall of the base 1. The stabilizing rod 61 is connected to one side of the bottom surface; an annular groove 624 is provided on the side wall of the shaft rod 623 near the bottom end, and internal threaded holes 625 are provided on both side walls of the positioning column 621. The two internal threaded holes 625 are connected to the inner cavity of the shaft hole 622, and the inner cavities of the two internal threaded holes 625 are rotatably connected to the limit screws 626, and one end of the limit screws 626 is inserted into the inner cavity of the annular groove 624. The top surface of the stabilizing rod 61 and both sides of the mounting hole 63 are provided with guide holes 67, and the inner cavities of the two guide holes 67 are inserted with guide columns 68, and the bottom ends of the two guide columns 68 are connected to the top surface of the pressing frame 65;

[0026] Through the positioning column 621 in the limiting assembly 6, it can be fixed to the side wall of the base 1, and the shaft rod 623 can be inserted and installed through the shaft hole 622, and at the same time, it can provide an opening space for the two internal threaded holes 625. Through the shaft rod 623, the stabilizing rod 61 can be installed and fixed, and the annular groove 624 can be provided with an opening space. Since the inner cavities of the two internal threaded holes 625 are rotatably connected to the limiting screw 626, and one end of the limiting screw 626 is inserted into the inner cavity of the annular groove 624, the limiting screw 626 can be inserted into the annular groove 624 of the shaft rod 623, which does not affect the rotation of the shaft rod 623 in the shaft hole 622, and can prevent the shaft rod 623 from sliding upward. Through the electric push rod 64, it can be installed in the mounting hole 63 on the stabilizing rod 61, and the clamping frame 65 can be installed at its telescopic end. Then, through the clamping frame 65, The anti-skid pad 66 can also be installed. When the hydraulic cylinder to be welded needs to be clamped, the shaft 623 is rotated at this time, so that the stabilizing rod 61 can be made perpendicular to the top of the base 1, and then the electric push rod 64 is extended, so that the clamping frame 65 and the anti-skid pad 66 can be driven downward synchronously, so that the bottom end of the anti-skid pad 66 can be against the upper surface of the hydraulic cylinder to be welded, so that the hydraulic cylinder to be welded can be clamped and limited, thereby ensuring the stability of the subsequent hydraulic cylinder welding. Since guide holes 67 are provided on the top surface of the stabilizing rod 61 and on both sides of the mounting hole 63, and guide columns 68 are inserted into the inner cavities of the two guide holes 67, and the bottom ends of the two guide columns 68 are connected to the top surface of the clamping frame 65, the stability of the clamping frame 65 during lifting and lowering can be improved through the guide columns 68 and the guide holes 67.

[0027] As shown in 5, the air suction component 7 includes a waste box 71 arranged in the notch 3, and the bottom surface of the inner cavity of the waste box 71 is provided with flame-retardant cotton 72, and the top surface of the flame-retardant cotton 72 is provided with a hollow mesh plate 73; a side wall of the waste box 71 and a position close to the bottom end are connected with an air suction part, and the four corners of the bottom surface of the waste box 71 are provided with limiting columns 76, and the bottom surface of the notch 3 is provided with a limiting groove for inserting the limiting column 76, and the air suction part includes an air pump 75 arranged on the side wall of the base 1, and the air inlet end of the air pump 75 is connected to the air outlet pipe 74, and one end of the air outlet pipe 74 passes through the side wall of the waste box 71, and the air outlet end of the air pump 75 is connected to an air filter;

[0028] Through the waste box 71 in the suction component 7, it can be inserted into the limiting groove at the notch 3 through the limiting column 76, and can also hold the flame retardant cotton 72 and the hollow mesh plate 73. Then, through the vacuum pump 75, it can be connected with the waste box 71 through the air outlet pipe 74. Therefore, when the hydraulic cylinder is welded at the notch 3, the welding waste slag will fall on the hollow mesh plate 73. At this time, the flame retardant cotton 72 can filter the welding slag to prevent the welding slag from damaging the vacuum pump 75. Since the welding will move downward under the pumping of the vacuum pump 75, it can prevent the smoke from floating upward, and the smoke pumped over can be filtered through the air filter, thereby improving the safety of the staff welding the hydraulic cylinder.

[0029] There are four brake casters 8, and the four brake casters 8 are respectively arranged at the four corners of the bottom surface of the base 1. The four brake casters 8 can not only play a supporting role, but also facilitate the staff to move the tooling, thereby improving the convenience of using the tooling.

[0030] During operation, the base 1 can provide a foundation for the arc groove 2, the notch 3 and the multiple ball grooves 4, and can also prevent the hydraulic cylinder to be welded through the arc groove 2. Since each ball groove 4 is provided with a ball 5 in the inner cavity, the ball 5 in the ball groove 4 can not only lift the hydraulic cylinder to be welded, but also make the hydraulic cylinder to be welded roll on its upper surface, so as to adjust the position of the hydraulic cylinder to be welded. Then, the notch 3 can be used to install the suction component 7, and it can be convenient for the staff to weld the hydraulic cylinder at its position. The welding slag and smoke generated during welding can be sucked away by the suction component 7, so as to improve the safety and hygiene of the staff in welding.

[0031] Through the positioning column 621 in the limiting assembly 6, it can be fixed to the side wall of the base 1, and the shaft rod 623 can be inserted and installed through the shaft hole 622, and at the same time, it can provide an opening space for the two internal threaded holes 625. Through the shaft rod 623, the stabilizing rod 61 can be installed and fixed, and the annular groove 624 can be provided with an opening space. Since the inner cavities of the two internal threaded holes 625 are rotatably connected to the limiting screw 626, and one end of the limiting screw 626 is inserted into the inner cavity of the annular groove 624, the limiting screw 626 can be inserted into the annular groove 624 of the shaft rod 623, which does not affect the rotation of the shaft rod 623 in the shaft hole 622, and can prevent the shaft rod 623 from sliding upward. Through the electric push rod 64, it can be installed in the mounting hole 63 on the stabilizing rod 61, and the clamping frame 65 can be installed at its telescopic end. Then, through the clamping frame 65, The anti-skid pad 66 can also be installed. When the hydraulic cylinder to be welded needs to be clamped, the shaft 623 is rotated at this time, so that the stabilizing rod 61 can be made perpendicular to the top of the base 1, and then the electric push rod 64 is extended, so that the clamping frame 65 and the anti-skid pad 66 can be driven downward synchronously, so that the bottom end of the anti-skid pad 66 can be against the upper surface of the hydraulic cylinder to be welded, so that the hydraulic cylinder to be welded can be clamped and limited, thereby ensuring the stability of the subsequent hydraulic cylinder welding. Since guide holes 67 are provided on the top surface of the stabilizing rod 61 and on both sides of the mounting hole 63, and guide columns 68 are inserted into the inner cavities of the two guide holes 67, and the bottom ends of the two guide columns 68 are connected to the top surface of the clamping frame 65, the stability of the clamping frame 65 during lifting and lowering can be improved through the guide columns 68 and the guide holes 67.

[0032] Through the waste box 71 in the suction component 7, it can be inserted into the limiting groove at the notch 3 through the limiting column 76, and can also hold the flame retardant cotton 72 and the hollow mesh plate 73. Then, through the vacuum pump 75, it can be connected with the waste box 71 through the air outlet pipe 74. Therefore, when the hydraulic cylinder is welded at the notch 3, the welding waste slag will fall on the hollow mesh plate 73. At this time, the flame retardant cotton 72 can filter the welding slag to prevent the welding slag from damaging the vacuum pump 75. Since the welding will move downward under the pumping of the vacuum pump 75, it can prevent the smoke from floating upward, and the smoke pumped over can be filtered through the air filter, thereby improving the safety of the staff welding the hydraulic cylinder.

[0033] In summary, the device can not only lift the hydraulic cylinder to be welded, but also make the hydraulic cylinder to be welded roll on its upper surface, so as to adjust the position of the hydraulic cylinder to be welded, facilitate the subsequent welding processing of the hydraulic cylinder, and at the same time, it can also handle the welding slag and smoke generated during welding, thereby improving the safety and hygiene of the workers in welding.
