[0018] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in conjunction with the embodiments.

[0019] Embodiment 1

[0020] See Figures 1 - 6, this embodiment provides an efficient turning and milling processing device for manufacturing the end cover of a square aluminum alloy fuel tank, including a base 1. A box cover 2 is arranged on the base 1. A first fixing frame 3 is arranged at the top middle of the box cover 2. A mounting frame 4 is hinged at the top of the first fixing frame 3. One end of the mounting frame 4 away from the first fixing frame 3 is fixedly connected to the top of the base 1. A grinding device 5 is arranged on the outer wall at the rear end of the box cover 2. A grinding component 6 is arranged on the grinding device 5. The grinding component 6 includes a support frame 61. A support plate 62 is fixedly connected to the top of the support frame 61. The number of support frames 61 is two. Through the two support frames 61, the use of the support plate 62 can be made more stable. A linear motor 63 is fixedly installed on the top of the support plate 62. The support plate 62 provides a supporting force for the use of the linear motor 63. A moving shaft of the linear motor 63 is fixedly connected to a fixing plate 64. The linear motor 63 provides power for the use of the fixing plate 64. A connecting column 65 is hinged at the middle front end of the fixing plate 64. The fixing plate 64 provides a supporting force for the use of the connecting column 65. A first ratchet wheel 66 is fixedly installed on the outer wall at the middle of the connecting column 65. The connecting column 65 provides a supporting force for the use of the first ratchet wheel 66, making the use of the first ratchet wheel 66 more convenient. The front end of the connecting column 65 is fixedly connected to the rear end of the grinding device 5. The connecting column 65 provides a supporting force for the use of the grinding device 5, enabling the grinding device 5 to process the edge of the box cover 2. A fine grinding block 67 is fixedly installed on the inner wall at the top front end of the grinding device 5. A rough grinding block 68 is fixedly installed on the inner wall below the front end of the grinding device 5. A side plate 610 is fixedly connected to the top right of the base 1. The base 1 provides a supporting force for the use of the side plate 610, preventing the side plate 610 from shaking during use and affecting the use result. A first pawl 69 is fixedly connected to the top of the side plate 610. The side plate 610 provides a supporting force for the use of the first pawl 69. The number of pawls on the first pawl 69 is six. When the first ratchet wheel 66 rotates through all the pawls on the first pawl 69, at this time, the rotation angle of the first ratchet wheel 66 is exactly 180 degrees. The bottom of the first ratchet wheel 66 meshes with the top of the first pawl 69. The side plate 610 provides a supporting force for the use of the first pawl 69.

[0021] When the above-mentioned device is in specific use, the linear motor 63 moves behind the box cover 2, driving the fine grinding block 67 and the coarse grinding block 68 on the grinding device 5 to grind the rear end of the box cover 2. After the linear motor 63 controls the grinding device 5 to grind one end of the box cover 2 once, by controlling the linear motor 63 to continue moving to the right, the first ratchet wheel 66 rotates 180 degrees on the first pawl 69, the connecting column 65 flips 180 degrees on the fixing plate 64, and the up-and-down positions of the fine grinding block 67 and the coarse grinding block 68 inside the grinding device 5 are swapped. At this time, control the linear motor 63 to move left and right on the box cover 2 again, so that both the coarse grinding block 68 and the fine grinding block 67 can grind one end of the box cover 2.

[0022] Embodiment 2

[0023] See Figures 2 - 9, on the basis of the first embodiment, an adjusting assembly 7 is provided on the base 1. The adjusting assembly 7 includes a hydraulic cylinder 72. A first hydraulic rod 71 is slidably connected to the inner surface of the middle part on the right side of the rear end of the hydraulic cylinder 72. A second hydraulic rod 73 is slidably connected to the inner surface of the right side of the front end of the hydraulic cylinder 72. A second pawl 74 is fixedly connected to the right side of the second hydraulic rod 73. The second hydraulic rod 73 provides power for the use of the second pawl 74, enabling the second pawl 74 to move left and right. A limiting frame 75 is slidably connected to the front end of the second pawl 74. The limiting frame 75 is in an "L" shape. By using the limiting frame 75, it can effectively prevent the second pawl 74 from shifting when moving left and right, affecting the use of the second ratchet wheel 78. A spring 76 is fixedly connected to the right side of the second pawl 74, affecting the use result of the spring 76. A vertical plate 77 is fixedly connected to the right side of the spring 76. The vertical plate 77 provides a supporting force for the use of the spring 76. The rear end of the second pawl 74 meshes with a second ratchet wheel 78. The number of paw teeth on the second pawl 74 is three. By moving the three paw teeth to the right, the second ratchet wheel 78 can be driven to rotate exactly 90 degrees. A support column 713 is fixedly connected to the inner side of the second ratchet wheel 78. The support column 713 provides a supporting force for the use of the second ratchet wheel 78, enabling the second ratchet wheel 78 to rotate stably. A circular groove 79 is formed at the bottom of the support column 713. A clamping groove 710 is formed on the inner wall of the circular groove 79. The number of the clamping grooves 710 is four. A spherical clamping rod 711 is slidably connected in the clamping groove 710. The number of the spherical clamping rods 711 is four. A fixing column 712 is fixedly connected to the inner side of the spherical clamping rod 711. The fixing column 712 provides a supporting force for the use of the spherical clamping rod 711. The bottom of the fixing column 712 is fixedly connected to the top of the base 1. The base 1 provides a supporting force for the use of the fixing column 712, enabling the fixing column 712 to be stably fixed above the base 1. The bottom of the vertical plate 77 is fixedly connected to the top of the base 1. The base 1 provides a supporting force for the use of the vertical plate 77, preventing the vertical plate 77 from shaking when the spring 76 is used. The bottom of the hydraulic cylinder 72 is fixedly connected to the top of the base 1. The base 1 provides a supporting force for the use of the hydraulic cylinder 72, effectively preventing the hydraulic cylinder 72 from moving during use and affecting the use of the first hydraulic rod 71 and the second hydraulic rod 73. The bottom of the support column 713 is slidably connected to the top of the base 1. The bottom of the box cover 2 is arranged on the support column 713. Through the cooperation of the support column 713 and the first fixing frame 3, the box cover 2 can be stably fixed above the base 1. The right side of the first hydraulic rod 71 is arranged on the left side of the push plate 611. The push plate 611 provides power for the use of the first hydraulic rod 71, making the use of the first hydraulic rod 71 more convenient.

[0024] When the above device is in specific use, after the grinder 5 finishes grinding one end of the box cover 2, the linear motor 63 is controlled to continue moving to the left, so that the push plate 611 on the left side of the fixed plate 64 at the front end of the linear motor 63 moves to the left, and the push plate 611 squeezes the first hydraulic rod 71 into the hydraulic cylinder 72, causing the second hydraulic rod 73 to move to the right. The movement of the second hydraulic rod 73 to the right drives the second pawl 74 to move to the right on the limit frame 75, causing the spring 76 on the right side of the second pawl 74 to be squeezed against the right vertical plate 77, enabling the second pawl 74 to drive the support column 713 below the rear second ratchet wheel 78 to rotate by 90 degrees. The rotation of the support column 713 drives the clamping groove 710 on the inner circular groove 79 to rotate by 90 degrees on the spherical clamping rod 711, enabling the spherical clamping rod 711 to be clamped in the clamping groove 710, ensuring that the support column 713 can rotate stably by 90 degrees, and the second ratchet wheel 78 outside the support column 713 can rotate stably by 90 degrees. The rotation of the support column 713 drives the first fixing frame 3 on the top box cover 2 to rotate by 90 degrees on the mounting frame 4, causing the box cover 2 to rotate stably by 90 degrees, and enabling the linear motor 63 to grind the other side of the box cover 2. At this time, under the action of the compressed spring 76, the second pawl 74 can move to the left on the limit frame 75, causing the second pawl 74 to squeeze the second hydraulic rod 73 to move into the left side of the hydraulic cylinder 72, making the first hydraulic rod 71 move to the right.

[0025] Embodiment Three

[0026] See Figures 3 - 10, on the basis of the second embodiment, a spraying assembly 8 is provided on the linear motor 63. The spraying assembly 8 includes a water storage tank 81. A water connection pipe 82 is fixedly connected to the front end of the water storage tank 81. The front end of the water connection pipe 82 penetrates through the fixing plate 64 and is fixedly connected to a water delivery pipe 85. The outer wall of the middle part of the water connection pipe 82 is slidably connected within a second fixing bracket 84. The number of the second fixing brackets 84 is two. The outer second fixing bracket 84 is arc-shaped. The inner second fixing bracket 84 is arranged above the rotating ring 83 and on the upper inner wall of the water connection pipe 82 and is a cuboid. A rotating ring 83 is slidably connected to the inner wall of the water connection pipe 82. The rotating ring 83 is circular, and the outer side of the rotating ring 83 is convex. The number of spherical balls on the outer side of the rotating ring 83 is three, which are distributed on the outer side of the rotating ring 83 in sequence. A transfer pipe 86 is fixedly installed at the top of the water delivery pipe 85. The number of the transfer pipes 86 is two. The fixing plate 64 provides a supporting force for the use of the transfer pipes 86 to prevent the transfer pipes 86 from shaking during use. A spray head 87 is fixedly installed at the front end of the transfer pipe 86. The inner side of the rotating ring 83 is fixedly connected to the outer wall of the rear end of the connecting column 65. The number of the water delivery pipes 85 is two, which can quickly transfer the water inside the water connection pipe 82 into the two transfer pipes 86. The rear end of the second fixing bracket 84 is fixedly connected to the front end of the fixing plate 64. The rotating ring 83 is arranged at the rear end of the first ratchet 66. One end of the transfer pipe 86 away from the spray head 87 is fixedly connected to the front end of the fixing plate 64. The number of the spray heads 87 is two. The bottom of the water storage tank 81 is fixedly connected to the top of the linear motor 63. The linear motor 63 provides a supporting force for the use of the water storage tank 81.

[0027] When the above device is specifically used, through the water inlet at the top of the water storage tank 81, water can be put into the interior of the water storage tank 81. The water in the water storage tank 81 is led out through the water connection pipe 82. When the connecting column 65 realizes a 180-degree flip under the movement of the first ratchet 66, it can synchronously drive the rotating ring 83 on the outer wall of the rear end of the connecting column 65 to rotate. Through the rotation of the rotating ring 83, the water inside the water connection pipe 82 is transferred into the water delivery pipe 85, and the water delivery pipe 85 transfers the water through the transfer pipe 86 into the spray head 87, so that the spray head 87 sprays the inner grinding device 5.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
