[0002] In the production process of new energy cylindrical battery shells, the materials needed include aluminum tubes. The cylindrical battery shells are obtained through the process of extrusion, cutting, preheating, stretching, rough cutting, cleaning and fine cutting of the aluminum tubes.

[0003] After being stretched, the aluminum tube needs to be cut into several short aluminum tubes of a certain length to form the prototype of a cylindrical battery shell. At present, when cutting the aluminum tube, the cutting knife needs to move downward or upward to cut the aluminum tube. The cutting knife will exert a certain pressure on the surface of the aluminum tube. Since the aluminum tube is used to make a cylindrical battery shell, the thickness of the aluminum tube is relatively thin, and the plasticity of the aluminum tube is relatively strong, which will cause the end of the cut part of the aluminum tube to deform, resulting in the cut short aluminum tube being unqualified and unable to adapt to the subsequent assembly of the entire battery. It needs to be further processed, thereby reducing the processing efficiency of the battery shell. Summary of the invention

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0035] like Figure 1-Figure 3 As shown, an aluminum tube processing positioning and cutting device includes a base 1, a cutting machine 2, a support seat 13 for placing the aluminum tube, a traction trolley 14 and a push plate 15, and the device also includes:

[0036] A fixing clamp 3, the fixing clamp 3 is fixedly mounted on the base 1, and the aluminum tube passes through the fixing clamp 3;

[0037] Guide cylinder 7, a bracket 4 is arranged on the base 1, a telescopic member 1 5 is movably mounted on the bracket 4, the output end of the telescopic member 1 5 is connected to a telescopic member 2 6, the output end of the telescopic member 2 6 is mounted with a guide cylinder 7, the other end of the telescopic member 2 6 is provided with a connecting rod 61, and the connecting rod 61 is hinged to the bracket 4;

[0038] The clamp 8 is installed on the guide cylinder 7. The guide cylinder 7 and the clamp 8 extend into the aluminum tube. The outer surface of the clamp 8 is arc-shaped and abuts against the inner wall of the aluminum tube.

[0039] Further, the fixture 8 comprises:

[0040] The fixed block 81, one end of the guide cylinder 7 is rotatably connected with the rotating cylinder 71, a driving member 72 is installed in the guide cylinder 7, a telescopic member 3 73 is installed at the output end of the driving member 72, and the output end of the telescopic member 3 73 passes through the rotating cylinder 71 and is fixedly connected to the fixed block 81;

[0041] The movable rod 1 82 and the movable rod 2 83, the outer periphery of the rotating drum 71 is rotatably connected with a plurality of movable rods 1 82, the other end of the movable rod 1 82 is rotatably connected with the movable rod 2 83, and the other end of the movable rod 2 83 is rotatably mounted on the fixed block 81;

[0042] The clamping plate 84 is movably mounted on one end of the movable rod 2 83 which is rotatably connected to the movable rod 1 82 .

[0043] In one case of the present embodiment, telescopic member 1 5, telescopic member 2 6 and telescopic member 3 73 can all be cylinders, or other components that can be telescopically driven; the driving member 72 can be a motor, or other components that can drive the fixed block 81 to rotate; the fixing clamp 3 does not apply any pressure to the aluminum tube, but only fits on the surface of the aluminum tube, so that the aluminum tube remains in a stable state when being cut; the side of the support seat 13 that contacts the aluminum tube is arc-shaped, which can effectively prevent the tube body of the aluminum tube from deforming when the aluminum tube is cut; the push plate 15 is driven to move by the traction trolley 14, so that the aluminum tube slowly approaches the cutting machine 2.

[0044] In actual application of this embodiment, the guide tube 7 drives the clamp 8 to extend into the aluminum tube by extending the telescopic member 2 6. When cutting the aluminum tube, the telescopic member 3 73 is extended to move the fixed block 81 in the direction away from the guide tube 7, and the fixed block 81 drives the movable rod 2 83 to move. Since both ends of the movable rod 2 83 are in a hinged state, the movable rod 2 83 cooperates with the movable rod 1 82 to move the clamp 84 outward, so that the plurality of clamps 84 are against the inner wall of the aluminum tube to support and clamp the inner wall of the aluminum tube, and the clamping position is close to the cutting position. In this way, when the cutting machine 2 moves down to cut the aluminum tube, the plurality of clamps 84 support the inner wall of the aluminum tube, thereby effectively preventing the end of the cut portion of the aluminum tube from being deformed, and preventing the cut aluminum tube from being unable to adapt to the subsequent assembly of the entire battery, so that the cut aluminum tube does not need to be processed again, thereby avoiding reducing the processing efficiency of the battery shell;

[0045] Since the plurality of clamping plates 84 cannot be flush with the cut portion of the aluminum tube, that is, the side of the clamping plates 84 away from the guide cylinder 7 cannot be flush with the end of the cut portion when the aluminum tube is cut, this will still cause deformation of the end of the cut aluminum tube. At this time, the cutting machine 2 is moved upward, and the telescopic member 26 is extended to move the plurality of clamping plates 84 in the direction away from the guide cylinder 7. The cut aluminum tube is blocked by the aluminum tube that has not been cut, that is, the long aluminum tube, so that the cut aluminum tube remains motionless. In this way, the plurality of clamping plates 84 will squeeze the deformed end portion of the cut aluminum tube, so that the end of the aluminum tube is restored to its original state, avoiding deformation of the end of the cut aluminum tube. There are gaps between the plurality of clamps 84, so that the portion of the aluminum tube that the plurality of clamps 84 cannot contact may still be in a deformed state. At this time, the telescopic member 3 73 is retracted so that the plurality of clamps 84 no longer press against the inner wall of the aluminum tube, and then the clamp 8 is rotated by the driving member 72 to change the position of the plurality of clamps 84. At this time, the telescopic member 3 73 is extended again so that the plurality of clamps 84 can contact the deformed position of the inner wall of the aluminum tube, and then the operation is performed according to the above steps, so that the end of the cut aluminum tube can be completely kept in an unchanged state, thereby effectively avoiding deformation of the end of the cut portion of the aluminum tube, so that there is no need to process the cut aluminum tube, thereby avoiding reducing the processing efficiency of the battery shell;

[0046] When the aluminum tube is cut, in addition to the possibility that the end of the cut aluminum tube may be deformed, the cut end of the long aluminum tube may also be deformed during cutting. At this time, the telescopic member 5 is extended to make the guide cylinder 7 rotate around the connecting rod 61 to move the cut aluminum tube downward, and the clamp 8 is released to make the cut aluminum tube fall into the external collection box. The guide cylinder 7 is returned to its original position through the telescopic member 5, and then the guide cylinder 7 is driven by the telescopic member 2 6 to extend the clamp 8 into the long aluminum tube so that the end of the long aluminum tube is located within the outer surface range of the clamp 84. At this time, several clamps 84 are unfolded to squeeze the deformed part of the end of the long aluminum tube to restore the end of the long aluminum tube to its original state. The position that the clamp 84 cannot squeeze is changed by the driving member 72, so that the end of the long aluminum tube can be completely kept in an unchanged state.

[0047] like Figure 2-Figure 4 As shown, a scraper 85 is provided on the side of the clamping plate 84 close to and away from the guide tube 7 . The scraper 85 is located at the edge of the clamping plate 84 , and the outer surface of the scraper 85 is flush with the outer surface of the clamping plate 84 .

[0048] It should be noted that after the cutting machine 2 has been running for a long time, the surface of the cutting knife is in a high temperature state. Therefore, when the cutting knife cuts the aluminum tube, the debris generated by the cutting may also be in a high temperature state, and the debris may enter the aluminum tube through the cut slit and adhere to the inner wall of the aluminum tube, which makes the inner wall of the aluminum tube rough. When the battery is assembled as a whole, it may cause the battery assembly to be unable to be inserted into the aluminum tube battery shell; based on this problem, a relevant structure is set to handle these debris.

[0049] In actual application of this embodiment, after the aluminum tube is cut, the telescopic member 2 6 will drive the clamp 8 to repair the end of the aluminum tube. At this time, the splint 84 is in a fit with the inner wall of the aluminum tube. When the splint 84 moves, the scraper 85 shovels up the debris attached to the inner wall of the aluminum tube, thereby avoiding the presence of debris attached to the inner wall of the aluminum tube; the position that the scraper 85 cannot contact can change the position of the splint 84 through the driving member 72, so that the scraper 85 can shovel off the debris on the inner wall of the aluminum tube that was originally unreachable, thereby improving the cleaning efficiency; the debris attached to the inner wall of the long aluminum tube is cleaned after the clamp 8 repairs the end of the long aluminum tube.

[0050] like Figure 3-Figure 5 As shown, a plurality of rotating members 74 are installed on the periphery of the guide cylinder 7, and the rotating axes of the rotating members 74 are perpendicular to the central axis of the guide cylinder 7. When the rotating members 74 rotate, the cut aluminum tubes are driven by the rotating members 74 to move away from the clamp 8.

[0051] Furthermore, movable grooves 841 are provided on both sides of the clamping plate 84 , and two groups of cleaning members 9 are installed in the movable grooves 841 from top to bottom, and a touch block 10 is installed between the two groups of cleaning members 9 .

[0052] Furthermore, the cleaning member 9 includes a rotating plate 91 and a cleaning plate 92, the rotating plate 91 and the cleaning plate 92 are fixedly connected, the rotating plate 91 is rotatably installed in the movable groove 841, and the rotating part of the rotating plate 91 is elastically installed, so that the rotating plate 91 and the cleaning plate 92 always have a tendency to rotate toward the movable groove 841, and two limit blocks 842 are arranged between the movable grooves 841, and the limit blocks 842 are flush with the side of the clamping plate 84, and a touch block 10 is movably installed between the two limit blocks 842, and an elastic member 12 is installed in the clamping plate 84, and the elastic member 12 is installed in the clamping plate 84. One end of the flexible member 12 is fixedly connected to the touch block 10, so that the touch block 10 always has a tendency to move toward the side away from the clamping plate 84. The top and bottom of the touch block 10 are provided with ear plates 101. When the end of the aluminum tube does not touch the touch block 10, the ear plate 101 is against the limit block 842. The ear plate 101 is located between the limit block 842 and the rotating plate 91. When the end of the aluminum tube touches the touch block 10, the ear plate 101 pushes the rotating plate 91 to rotate the rotating plate 91, so that the cleaning plate 92 rotates to the outside of the movable groove 841.

[0053] Furthermore, when the touch block 10 is pushed into the movable groove 841 by the end of the aluminum tube, the rotating plate 91 rotates to a horizontal state, and the upper and lower rotating plates 91 remain parallel.

[0054] It should be noted that after the aluminum tube is cut, a large number of burrs will be generated on its end surface, which will affect the quality of the cut aluminum tube; in addition, the scraper 85 may not be able to clean up all the debris attached to the inner wall of the aluminum tube; according to the above problems, relevant structures are set to solve them.

[0055] In one case of this embodiment, the elastic member 12 may be a spring or other elastically retractable member; the elastic rotating portion of the rotating plate 91 is provided with a torsion spring; the rotating member 74 may be composed of a wheel and a motor for driving the wheel to rotate; the outer surface of the telescopic member 6 is provided with a thickened shell (not shown in the figure), and the diameter of the thickened shell is equal to the inner diameter of the aluminum tube; the surface of the cleaning plate 92 is in an inclined state, so as to facilitate the shoveling of burrs or debris.

[0056] In actual application of this embodiment, after the aluminum tube is cut and the end of the aluminum tube is repaired, the clamp 8 is loosened until the inner wall of the cut aluminum tube contacts the rotating member 74. After the inner wall of the aluminum tube contacts the rotating member 74, the rotating member 74 drives the aluminum tube to move away from the clamp 8, so that the aluminum tube is sleeved on the thickened shell on the surface of the telescopic member 2 6 to keep the aluminum tube stable. Then the telescopic member 2 6 is contracted and the telescopic member 3 73 is extended at the same time to make the clamp 84 expand outward, and a plurality of clamps 84 move toward the end face of the aluminum tube so that the touch block 10 contacts the end face of the aluminum tube. In this way, the touch block 10 will move into the movable groove 841, and the ear plate 101 on the touch block 10 will squeeze the rotating plate 91 to make the rotating plate 91 rotate until the upper and lower cleaning plates are 92 are in contact with the outer surface and inner wall of the aluminum tube respectively. At this time, the clamp 8 is rotated by the driving member 72, so that the upper and lower cleaning plates 92 move along the end surface of the aluminum tube and scrape the inner and outer walls of the aluminum tube to clean up the burrs and debris on the aluminum tube, further improving the cleaning efficiency and ensuring the quality of the cut aluminum tube; after cleaning, the telescopic member 2 6 is extended and the telescopic member 3 73 is contracted to make the clamp 8 away from the aluminum tube, and then the rotating member 74 is reversed to make the aluminum tube fall off the thickened shell and fall into the external collection box through the clamp 8. When the touch block 10 is not bound, the elastic member 12 has the rebound ability to make the touch block 10 slowly return to its original position, and then the torsion spring has the rebound ability to make the upper and lower cleaning members 9 return to the movable groove 841;

[0057] After cleaning the cut aluminum tube, the telescopic member 2 6 is extended and the telescopic member 3 73 is extended to make the clamp 8 close to the long aluminum tube, so that the touch block 10 on the other side of the clamp 8 contacts the end face of the long aluminum tube, so that the upper and lower cleaning plates 92 move along the end face of the long aluminum tube and scrape the inner and outer walls of the long aluminum tube to clean up the burrs and debris on the long aluminum tube.

[0058] Furthermore, friction plates 11 are embedded on both sides of the clamping plate 84 . The friction plates 11 are divided into two sections. The two sections of the friction plates 11 are located on both sides of the touch block 10 .

[0059] It should be noted that burrs or debris on the aluminum tube may be at the end surface of the aluminum tube, and the upper and lower cleaning plates 92 cannot clean the burrs or debris on the end surface of the aluminum tube; in addition, when the aluminum tube is cut, the high-temperature cutting knife may cause the end surface of the aluminum tube to soften due to heat, which may cause the end surface of the aluminum tube to be uneven, thereby affecting the quality of the cut aluminum tube; according to the above problems, relevant structures are set to solve them.

[0060] In one case of this embodiment, the friction plate 11 may be sandpaper, or other components that can grind the end surface of the aluminum tube.

[0061] When this embodiment is actually used, a number of clamping plates 84 rotate around the end face of the aluminum tube, and the end face of the aluminum tube contacts the friction plate 11. The friction plate 11 will grind the end face of the aluminum tube, thereby grinding away burrs or debris on the end face of the aluminum tube, and at the same time grinding the end face of the aluminum tube to make it smooth, avoiding the situation where the end face of the aluminum tube is uneven.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
