[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] like Figures 1 to 7 As shown, an electrode end surface processing device includes a fixed frame 2, the fixed frame 2 is provided with a sliding movable frame 3, and the fixed frame 2 is provided with a driving device 4 for driving the movable frame 3 to move in the horizontal direction; a lifting arm 5 is provided on the movable frame 3, and a first push rod motor 6 is fixed on the movable frame 3, and the push rod of the first push rod motor 6 is connected to the lifting arm 5 for driving the lifting arm 5 to move in the height direction; a first rotating shaft 7 and a second rotating shaft 8 are rotatably provided on the lifting arm 5, and the first rotating shaft 7 and the second rotating shaft 8 are arranged along the moving direction of the movable frame 3, and the upper and lower ends of the first rotating shaft 7 are detachably provided with coarse grinding wheels 9; the upper and lower ends of the second rotating shaft 8 are detachably provided with fine grinding wheels 10; a driving structure 11 for driving the first rotating shaft 7 and the second rotating shaft 8 to rotate is provided on the lifting arm 5; a replacement mechanism 12 for removing or installing the coarse grinding wheel 9 at the upper and lower ends of the first rotating shaft 7 is provided on the fixed frame 2.

[0040] In this application, two welding copper electrodes 100 are involved in the resistance welding device. During the welding process, the parts are placed between the two copper electrodes 100, and then welding is achieved by bringing one of the copper electrodes 100 close together. However, during the welding process, an oxide layer will be formed after several weldings, and polishing treatment is required to eliminate the oxide layer.

[0041] When the copper pole 100 needs to be polished, the movable frame 3 is driven horizontally by the driving device 4, so that the coarse grinding wheel 9 on the lifting arm 5 at the end of the movable frame 3 moves to between the two copper poles 100, and then the lifting arm 5 is driven to move up and down by the first push rod motor 6, so that the coarse grinding wheels 9 at the upper and lower ends of the first rotating shaft 7 can polish the upper and lower copper poles 100, and then the movable frame 3 is continued to be driven to move by the driving device 4, so that the fine grinding wheel 10 moves to between the two copper poles 100, and then the lifting frame is driven by the first push rod motor 6, and then the fine grinding wheel 10 is used to polish the two copper poles 100.

[0042] Generally, the coarse grinding wheel 9 is a grinding wheel, while the fine grinding wheel 10 is a diamond grinding wheel. As a result, the coarse grinding wheel 9 wears out faster during use. Therefore, a replacement structure is designed. After the grinding wheel reaches a predetermined number of uses, the coarse grinding wheel 9 can be directly replaced through the replacement structure. The fine grinding wheel 10 is more wear-resistant and can be manually replaced after a long time. This avoids the problem of frequent replacement of the coarse grinding wheel 9 and reduced efficiency, or the problem of poor grinding effect caused by not replacing the coarse grinding wheel 9 for a long time.

[0043] Specifically, a displacement sensor for detecting the number of times the movable frame 3 moves is fixed on the fixed frame 2 .

[0044] The displacement sensor can detect the number of times the movable frame 3 moves. If no movement is detected, it means that the coarse grinding wheel 9 and the fine grinding wheel 10 have been used for grinding once. After the detection reaches the preset number of times, the coarse grinding wheel 9 can be replaced through the replacement structure, or the fine grinding wheel 10 can be replaced manually.

[0045] Specifically, the driving structure 11 includes a first gear 111, a second gear 112, a driving gear 113 and a first driving motor 114. The first gear 111 is coaxially arranged with the first rotating shaft 7, the second gear 112 is coaxially arranged with the second rotating shaft 8, the first driving motor 114 is fixed on the lifting arm 5, the driving gear 113 is fixed on the output shaft of the first driving motor 114, and the driving gear 113 is engaged with the first gear 111 and the second gear 112 through a toothed belt 115.

[0046] The first drive motor 114 is started, driving the driving gear 113 to rotate. The driving gear 113 drives the first gear 111 and the second gear 112 to rotate through the toothed belt 115. The first gear 111 and the second gear 112 respectively drive the first rotating shaft 7 and the second rotating shaft 8 to rotate, thereby driving the coarse grinding wheel 9 and the fine grinding wheel 10 to rotate respectively.

[0047] Specifically, the driving device 4 includes a second push rod motor, the second push rod motor is fixed on the fixed frame 2 , and a push rod of the second push rod motor is connected to the movable frame 3 .

[0048] The second push rod motor drives the moving frame 3 to move horizontally. The lifting arm 5 on the moving frame 3 can move between the replacement mechanism 12 and the two copper poles 100.

[0049] Specifically, the invention further comprises two blowing pipes 13 which are capable of blowing air toward the rough grinding wheel 9 or the two fine grinding wheels 10 .

[0050] The air blowing pipe 13 can be started to blow away the particles ground off the surface of the coarse grinding wheel 9 and the fine grinding wheel 10, so as to avoid affecting the next grinding and causing the grinding effect to deteriorate.

[0051] Specifically, the replacement mechanism 12 includes a first guide rail 121, a second guide rail 122, two third gears 123, a chain 124, a plurality of clamping components 125 and a second drive motor 126. The first guide rail 121 and the second guide rail 122 are fixed to the fixed frame 2. The first guide rail 121 is provided with a first guide groove 1211, and the second guide rail 122 is provided with a second guide groove 1221. The first guide rail 121 and the second guide rail 122 are parallel to each other and form a gap 127. The coarse grinding wheel 9 on the lifting arm 5 can move into the gap 127. The two third gears 123 are rotatably set on the fixed frame 2. The chain 124 is set A chain 124 is provided on the two third gears 123, and at least part of it is provided in the first guide groove 1211 and the second guide groove 1221. A plurality of clamping components 125 are fixedly connected to the chain 124, and each clamping component 125 can enter the first guide groove 1211 or the second guide groove 1221. The clamping component 125 can slide with the first guide groove 1211 or the second guide groove 1221; the second drive motor 126 is fixed on the fixed frame 2, and the output shaft of the second drive motor 126 is transmission-connected to one of the third gears 123, for driving the third gear 123 to rotate.

[0052] In this mechanism, the coarse grinding wheel 9 is set on the clamping parts 125 in advance, and at the same time, two of the clamping parts 125 can be kept empty.

[0053] The driving device 4 drives the movable frame 3 to move, and causes the rough grinding wheel 9 above the first rotating shaft 7 to be clamped into the vacant clamping part 125, and then the first push rod motor 6 drives the lifting arm 5 to descend, so that the upper rough grinding wheel 9 is disengaged from the first rotating shaft 7, and then the driving device 4 drives the lifting arm 5 away from the replacement structure, and then the first push rod motor 6 descends, and drives the lifting arm 5 to descend, so that the rough grinding wheel 9 below the first rotating shaft 7 can be aligned with another vacant clamping part 125, and the driving device 4 drives the movable frame 3 to move again and drives the rough grinding wheel 9 below the first rotating shaft 7 to be clamped into the clamping part 125, and the first driving motor 114 drives the lifting arm 5 to rise, so that the lower rough grinding wheel 9 is disengaged and remains in the clamping part 125. At this time, the rough grinding wheels 9 above and below the first rotating shaft 7 have been disassembled.

[0054] The second drive motor 126 drives one of the third gears 123 to rotate, and the third gear 123 drives the chain 124 to operate. The chain 124 drives the clamping component 125 to move, removing the two rough grinding wheels 9 that have just been removed and bringing in new rough grinding wheels 9. At this time, the movement of the first rotating shaft 7 causes the upper end of the first rotating shaft 7 to be inserted into the rough grinding wheel 9 located above, thereby moving the first rotating shaft 7 and causing the lower end of the first rotating shaft 7 to be inserted into the rough grinding wheel 9 located below, thereby completing the replacement of the two rough grinding wheels 9.

[0055] The insertion path of the first rotating shaft 7 is to insert it into the upper rough grinding wheel 9 from bottom to top, and then horizontally bring the rough grinding wheel 9 out of the clamping component 125. Then, after adjusting the height of the first rotating shaft 7, move the position of the first rotating shaft 7 and insert the first rotating shaft 7 from top to bottom into the lower rough grinding wheel 9. Then, the first rotating shaft 7 moves horizontally to bring the lower rough grinding wheel 9 out of the clamping component 125, thereby completing the installation of the two rough grinding wheels 9.

[0056] The arrangement of the first guide rail 121 and the second guide rail 122 prevents the clamping member 125 from rocking after entering the first guide groove 1211 and the second guide groove 1221. This allows the first rotating shaft 7 to be accurately inserted into the center hole of the rough grinding wheel 9 after moving to a predetermined position, allowing the rough grinding wheel 9 to be accurately removed and replaced. In a specific implementation, when the clamping member 125 enters the first guide groove 1211 or the second guide groove 1221, the upper and lower surfaces of the clamping member 125 can contact the upper and lower surfaces of the first guide groove 1211 and the second guide groove 1221, respectively, thereby achieving stable movement of the clamping member 125.

[0057] Specifically, a first support plate 128 is fixed on the first guide rail 121 , and a second support plate 129 is fixed on the second guide rail 122 .

[0058] The first support plate 128 and the second support plate 129 can move upward or downward on the first rotating shaft 7 to provide a movable support for the rough grinding wheel 9, thereby facilitating the first rotating shaft 7 to be inserted into the center hole of the rough grinding wheel 9.

[0059] Specifically, the clamping component 125 includes a guide portion 1251 and a clamping portion 1252. The guide portion 1251 can slideably cooperate with the first guide groove 1211 and the second guide groove 1221. When the guide portion 1251 is located in the first guide groove 1211 or the second guide groove 1221, the clamping portion 1252 extends out of the first guide groove 1211 or the second guide groove 1221. The clamping portion 1252 is provided with a receiving groove 12521 for accommodating the coarse grinding wheel 9. Limiting portions 12522 are provided along the upper and lower edges of the receiving groove 12521, and an elastic limiting piece 14 is provided on the inner wall of the receiving groove 12521.

[0060] The wire portion can slide with the first guide groove 1211 and the second guide groove 1221 to limit the movement of the clamping component 125 toward the opening direction, thereby improving the accuracy of the position of the clamping component 125 and facilitating the first rotating shaft 7 to be inserted into the center hole of the rough grinding wheel 9.

[0061] By setting the elastic limiting piece 14, the rough grinding wheel 9 can be conveniently inserted into the accommodating groove 12521 and stuck in the limiting groove, so that the position of the rough grinding wheel 9 can be set to a preset position, but the rough grinding wheel 9 can be conveniently taken out or installed.

[0062] When the rough grinding wheel 9 is inserted into the receiving groove 12521 , the upper and lower surfaces of the rough grinding wheel 9 can respectively abut against the upper and lower walls of the receiving groove 12521 . The interior of the receiving groove 12521 is configured to be in an arc shape that is adapted to the rough grinding wheel 9 .
