DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 3 , a hydraulic cylinder welding part cylinder bottom processing device shown in the figure includes a clamping part 1 for connecting the cylinder barrel of the hydraulic cylinder and a docking part 2 for fixing the earring; and two connecting plates 3, the two connecting plates 3 are respectively docked with the clamping part 1 and the docking part 2, and the two connecting plates 3 are equipped with a rotating part 4 for driving the clamping part 1 and the docking part 2 to rotate; and a welding gun 5, the welding gun 5 is arranged between the hydraulic cylinder and the earring, and is used for welding after the two are docked; and a side plate 6 is arranged between the two connecting plates 3, and a welding auxiliary component 7 for cleaning debris on the adjacent surfaces of the hydraulic cylinder and the earring is installed on the side plate 6, and a linkage component 8 is also installed on the side plate 6, and the linkage component 8 is docked with the two rotating parts 4, and the two rotating parts 4 are driven by the linkage component 8;

[0029] In this solution, the designed clamping part 1 and docking part 2 are respectively docked and positioned with the hydraulic cylinder and the earring, and the earring can be controlled to move toward the hydraulic cylinder. When it moves to contact with the welding auxiliary component 7, the adjacent surfaces of the two can be cleaned and the impurities and dust on the surface can be processed. Then the welding auxiliary component 7 rotates away, the earring and the hydraulic cylinder are fitted together, the welding auxiliary component 7 contacts the linkage component 8, and drives the two rotating parts 4 to drive the hydraulic cylinder and the earring to rotate. Finally, the welding gun 5 moves to the fitting point of the earring and the hydraulic cylinder, and the welding operation is performed while the earring and the hydraulic cylinder rotate synchronously.

[0030] For further information, see Figure 1 - Figure 3 as well as Figure 7 and Figure 8 The rotating part 4 includes a rotating gear ring 9 rotatably mounted on the connecting plate 3. The two rotating gear rings 9 on the two rotating parts 4 are respectively fixed to the clamping part 1 and the docking part 2. A rotating gear 10 meshing with the rotating gear ring 9 is rotatably mounted on the connecting plate 3 through a bearing. A docking gear 11 connected to the linkage assembly 8 is rotatably mounted on the connecting plate 3. A toothed belt 12 is meshed between the docking gear 11 and the rotating gear 10.

[0031] Also, see Figure 1 - Figure 6 The linkage assembly 8 includes a linkage rod 13 that is rotatably docked with the two side plates 6, and a linkage gear 14 is fixed on the linkage rod 13. One of the linkage rods 13 is fixed to one of the docking gears 11, and an inner rod 15 is slidably inserted in the other linkage rod 13 and fixed to the other docking gear 11 through the inner rod 15.

[0032] The principle of driving the two rotating parts 4 to rotate through the linkage assembly 8 is as follows:

[0033] First, the welding auxiliary component 7 is rotated until it contacts the linkage component 8, and then the linkage rod 13 is driven to rotate, and the inner rod 15 is driven to rotate, so that the two docking gears 11 rotate synchronously. Afterwards, under the action of the toothed belt 12, the rotating gear 10 rotates synchronously, driving the rotating gear ring 9 to follow the rotation, so that the clamping part 1 and the docking part 2 rotate synchronously in the same direction, and the hydraulic rod and the earring rotate synchronously, which is convenient for welding operation.

[0034] For further information, see Figure 1 - Figure 6 The welding auxiliary component 7 includes a rotating rod 16 rotatably mounted between the two side plates 6, a rotating plate 17 is fixed on the outer side of the rotating rod 16, a cleaning column 18 is rotatably mounted on the rotating plate 17, a linkage gear ring 19 is fixed on the cleaning column 18, a double gear 20 is rotatably mounted on the rotating plate 17, a toothed belt 22 meshing with the linkage gear 14 is sleeved on the outer side of the small gear in the double gear 20, and the large gear in the double gear 20 is adapted to the linkage gear 14. A driving motor 23 for driving the double gear 20 to rotate is fixed on the outer side of the rotating plate 17 through a motor frame, and a rotating motor 24 for driving the rotating rod 16 to rotate is fixed on the side plate 6;

[0035] In order to facilitate the cleaning of debris on the adjacent surfaces of the earring and the hydraulic cylinder, cleaning brushes 25 are fixed on both sides of the cleaning column 18. The cleaning brushes 25 are detachable and can be replaced after being worn out or having too many foreign objects attached.

[0036] In this solution, when the welding auxiliary component 7 is between the earring and the hydraulic cylinder:

[0037] At this time, the earring gradually moves toward the hydraulic cylinder, and during the movement, it gradually contacts the outer side of the cleaning column 18, and at the same time, the other end of the cleaning column 18 contacts the outer end of the hydraulic cylinder. Driven by the driving motor 23, the double gear 20 is driven to rotate, and the toothed belt 22 is used to drive the linkage gear ring 19 to rotate, so that the cleaning column 18 and the cleaning brush 25 rotate synchronously, so as to clean the adjacent surfaces of the earring and the hydraulic cylinder, remove attachments and rust, and facilitate the subsequent welding operation after the two are bonded together;

[0038] When the welding auxiliary component 7 is rotated and separated from between the earring and the hydraulic cylinder:

[0039] At this time, the rotating motor 24 drives the rotating rod 16 to rotate, and the rotating plate 17 and the cleaning column 18 are rotated, as shown in FIG. Figure 6 As shown, at this time, the large gear on the double gear 20 will mesh with the linkage gear 14, and under the action of the driving motor 23, the linkage gear 14 will follow the rotation, driving the linkage rod 13 to rotate, so that the clamping part 1 and the docking part 2 rotate synchronously, thereby driving the hydraulic cylinder and the earring to rotate synchronously after docking, which is convenient for welding.

[0040] For further information, see Figure 1 - Figure 3 as well as Figure 7 The docking part 2 includes a plug 26 adapted to the inner hole of the earring, a docking seat 27 is fixed to one end of the plug 26, and a threaded rod 28 is fixed to the other end. A docking column 29 fixed to the rotating gear ring 9 is fixed to the outer end of the docking seat 27, and a cap 30 is threadedly sleeved on the outer side of the threaded rod 28. An electric push rod is fixed to the outer end of the connecting plate 3, and the connecting plate 3 and the earring are driven to move toward the cylinder barrel of the hydraulic cylinder by the electric push rod;

[0041] Also, see Figure 1 - Figure 3 as well as Figure 8 The clamping part 1 includes a connecting ring 31 fixed to the rotating gear ring 9, and a plurality of clamping members 32 are installed in the connecting ring 31; wherein the clamping member 32 includes a threaded column 33 threadedly inserted on the connecting ring 31, one end of the threaded column 33 is fixed with a rotating cap, and the other end is rotatably connected with the docking piece 21.

[0042] In this solution, the principle of the clamping part 1 and the docking part 2 fixing the hydraulic cylinder and the earring is:

[0043] First, the personnel loosen and open the abutting cap 30, and then insert the earring into the docking column 29, and then loosen the abutting cap 30 again to complete the docking and fixation of the earring. After that, the personnel insert the cylinder body of the hydraulic cylinder into the connecting ring 31, and by screwing the threaded column 33, the docking piece 21 is abutted against the outer wall of the hydraulic cylinder, thereby fixing the hydraulic cylinder from the outside. After the earring and the hydraulic cylinder are fixed, the electric push rod is used to push the docking seat 27 to move, so that the earring slowly approaches the hydraulic cylinder. After completing the cleaning of the adjacent surfaces of the earring and the hydraulic cylinder, it is moved until the earring and the hydraulic cylinder are fitted together, thereby driving the earring and the hydraulic cylinder to automatically fit together, and the fitting is precise, which makes the welding accuracy higher.

[0044] Example 2: Please refer to Figure 1 - Figure 3 as well as Figure 7 and Figure 8 This embodiment further explains the first embodiment, and the difference lies in that the structures of the offset cap 30 and the rotating cap are optimized.

[0045] Specifically, in order to improve the stability of the abutting cap 30 in docking with the earring, rubber pads are provided on the adjacent surfaces of the abutting cap 30 and the docking seat 27. At the same time, in order to facilitate the rotation adjustment of the abutting cap 30 and the rotating cap, anti-slip patterns are engraved on the outer sides of the abutting cap 30 and the rotating cap.
