Description

Technical Field

[0001] The invention relates to a conductive bar shell cutting device and a conductive bar shell cutting method. Background Art

[0002] In the charging facilities of new energy vehicles, copper busbars, aluminum busbars and other materials are used to connect power components and realize the transmission of electric energy. During the production process of these metal conductive buses, a protective shell is set on the outside of the conductive body. When the conductive busbar is connected to other components, the shell at the end needs to be removed. Most of the existing equipment for cutting shells usually places the cutting blades, saw blades and other cutting workpieces on one side of the machine tool. The cutting workpiece can only be cut on the side facing it. Therefore, during the process of cutting the shell, the conductive busbar needs to be constantly flipped to adjust the cutting surface until a full circle is cut. At the same time, in order to maintain stability during cutting, the conductive busbar needs to be re-fixed after each adjustment, which will result in a time-consuming and inefficient cutting operation, and errors are easily generated between the cutting surfaces before and after flipping.

One side end face of the positioning pin constitutes the positioning surface; the positioning pin is adjustable along the length direction on the connecting frame, or the positioning pin is detachably connected to the connecting frame.

[0012] In some embodiments, the cutting portion has a first cutting surface and a second cutting surface respectively arranged on two different sides in the thickness direction, the first cutting surface is located on a side close to the fixing frame, and the second cutting surface is located on a side away from the fixing frame, the first cutting surface extends perpendicular to the rotation axis, and the second cutting surface extends obliquely from the inside to the outside along a direction perpendicular to the rotation axis, and the outer side of the second cutting surface is connected to the first cutting surface to form a cutting edge.

DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings to make the advantages and features of the present invention more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0039] See also Figures 1 to 4The conductive bar shell cutting device shown includes a drive mechanism 1, a guide block 2 and a cutting blade 3, wherein the drive mechanism 1 is movably arranged and includes a rotating shaft 11 that can rotate around its own axis. The guide block 2 is rotatably arranged on the rotating shaft 11 around the axis of the rotating shaft 11. The guide block 2 is relatively fixedly arranged along the axial direction of the rotating shaft 11. The circumferential side of the guide block 2 has a supporting surface 21, and the supporting surface 21 is an arc-shaped surface with the axis of the rotating shaft 11 as the center line. The cutting blade 3 is fixed on the rotating shaft 11 and is spaced apart from the guide block 2 along the axial direction of the rotating shaft 11. The cutting blade 3 has a cutting portion 31 for cutting the conductive bar 10, and the vertical distance between the outer edge of the cutting portion 31 and the axis of the rotating shaft 11 is greater than the vertical distance between the supporting surface 21 and the axis of the rotating shaft 11.

[0040] In this embodiment, the drive mechanism 1 includes a drive module 12 for driving the rotating shaft 11 to rotate about its own axis. When the drive mechanism 1 is activated, the drive module 12 drives the rotating shaft 11 to rotate, which in turn drives the cutting blade 3 to rotate, thereby enabling the cutting operation to be performed using the cutting blade 3. Because the guide block 2 is rotatably connected to the rotating shaft 11, when the rotating shaft 11 rotates, it does not drive the guide block 2 to move. When the cutting device is in operation, the abutment surface 21 is aligned with the outer shell 102 of the conductive bar 10 and remains aligned with the outer shell 102 of the conductive bar 10, driving the drive mechanism 1 to move along the circumference of the conductive bar 10. Because the cutting portion 31 of the cutting blade 3 extends beyond the abutment surface 21, when the abutment surface 21 is aligned with the outer surface of the conductive bar 10, the cutting portion 31 can cut the outer shell 102 of the conductive bar 10 and effectively control the cutting depth. In the working state, as the driving mechanism 1 moves along the circumference of the conductive bar 10, the cutting blade 3 can cut the conductive bar 10 along the circumference, and the cutting operation can be completed in one go. During the cutting process, there is no need to adjust the position and state of the conductive bar 10 or to re-fix the conductive bar 10, which simplifies the operation and improves efficiency.

[0041] In this embodiment, see Figure 5 As shown, the conductive bar 10 includes a conductive body 101 for transmitting electrical energy, and a shell 102 wrapped around the outside of the conductive body 101. In this embodiment, when the driving mechanism 1 moves around the conductive bar 10 once, the cutting blade 3 completes the cutting operation around the conductive bar 10, thereby separating the shell 102 at the end of the conductive bar 10 and removing it. In this embodiment, the conductive body 101 of the conductive bar 10 is made of an aluminum alloy material, and an insulating rubber layer is provided on the outside thereof. The shell 102 is arranged on the outside of the insulating rubber layer. The shell 102 is made of a metal material, specifically, the shell 102 is made of aluminum. In some embodiments, the conductive body 101 is made of other metal materials such as copper, or the shell 102 is made of other metal materials.

[0042] In this embodiment, the abutment surface 21 is annular with the axis of the rotating shaft 11 as the center line, and the distance from each point of the abutment surface 21 to the axis of the rotating shaft 11 is consistent, thereby ensuring that the cutting depth of the cutting blade 3 is consistent when the driving mechanism 1 moves around the conductive bar 10.

[0043] In this embodiment, a bearing 20 is sleeved on the rotating shaft 11, and the guide block 2 is annular and sleeved on the outer side of the bearing 20, so as to realize the rotation connection between the guide block 2 and the rotating shaft 11. Figure 8 As shown, the guide block 2 includes a collar sleeved around the outer side of the bearing 20 and an annular protrusion extending outward from the outer circumference of the collar. The outer surface of the annular protrusion constitutes a contact surface 21. Preferably, the width of the contact surface 21 is 3 mm to 10 mm. This ensures that the contact surface 21 and the conductive bar 10 can maintain stable contact during the movement of the drive mechanism 1, thereby ensuring the stability of the movement of the drive mechanism 1. At the same time, it can reduce the contact area between the contact surface 21 and the conductive bar 10, thereby reducing the frictional resistance between the guide block 2 and the conductive bar 10.

[0044] In this embodiment, the cutting blade 3 is circular and fixed coaxially with the rotating shaft 11. The cutting portion 31 of the cutting blade 3 is located outside the circumference of the cutting blade 3. In this embodiment, the driving mechanism 1 is a motor.

[0045] In some preferred embodiments, the axial spacing between the cutting blade 3 and the guide block 2 along the rotating shaft 11 is 5 mm to 10 mm. While ensuring that the operation of the cutting blade 3 is not interfered with, reducing the distance between the cutting blade 3 and the guide block 2 can improve the cutting accuracy.

[0046] In this embodiment, the cutting device includes a first limiting mechanism and a second limiting mechanism. The second limiting mechanism is movably arranged on the first limiting mechanism along a first direction, and the driving mechanism 1 is movably arranged on the second limiting mechanism along a second direction. The first direction and the second direction are perpendicular to each other, and the first direction and the second direction are respectively perpendicular to the axial direction of the rotating shaft 11. In this embodiment, the first direction is the vertical direction, the second direction is the horizontal direction, and the rotating shaft 11 also extends in the horizontal direction. With the cooperation of the first limiting mechanism and the second limiting mechanism, the driving mechanism 1 can be prevented from moving axially along the rotating shaft 11, thereby preventing the cutting blade 3 from moving axially along the rotating shaft 11, so that the driving mechanism 1 and the cutting blade 3 can only move in a plane perpendicular to the rotating shaft 11, ensuring that the cutting blade 3 cuts in the same plane when the driving mechanism 1 moves around the conductive bar 10, thereby achieving the effect of improving the cutting quality and improving the yield rate.

[0047] Specifically, see Figures 6 to 8As shown, the first limiting mechanism includes two support frames 41 spaced apart along the second direction, and the second limiting mechanism includes a lifting platform 42 extending along the second direction, i.e., the horizontal direction. The lifting platform 42 is mounted between the two support frames 41, and the lifting platform 42 can be slidably arranged up and down relative to the support frames 41. The driving mechanism 1 is slidably arranged on the lifting platform 42 along the length direction of the lifting platform 42. In this embodiment, the support frame 41 is provided with a guide rail 40 extending along the up and down direction, and the lifting platform 42 is slidably connected to the guide rail 40, thereby providing a guide for the up and down sliding of the lifting platform 42. In this embodiment, the lifting platform 42 is provided with a guide rail 40 extending along the second direction, and the driving mechanism 1 is slidably connected to the guide rail 40 on the lifting platform 42, thereby providing a guide for the sliding of the driving mechanism 1.

[0048] In this embodiment, the cutting device includes a fixing frame 5, on which a fixing mechanism for fixing the conductive bar 10 is provided. A working space is provided on one side of the fixing frame 5, and the driving mechanism 1 is movably arranged in the working space. Figure 3 、 Figure 4 As shown, the drive mechanism 1 is arranged on one side of the fixed frame 5 parallel to the axial direction of the rotating shaft 11, and one end of the conductive bar 10 fixed on the fixed frame 5 extends into the working space. The drive mechanism 1 moves in the working space and uses the cutting blade 3 to cut the shell 102 of the conductive bar 10 that extends into the working space.

[0049] In this embodiment, the guide block 2 is located on the side of the cutting blade 3 away from the fixed frame 5, which can save space in the cutting device along the axial direction of the rotating shaft 11. In this embodiment, the cutting portion 31 has a first cutting surface 311 and a second cutting surface 312 respectively provided on two different sides in the thickness direction. The first cutting surface 311 is located on the side close to the fixed frame 5, and the second cutting surface 312 is located on the side away from the fixed frame 5. Figure 8 As shown, the first cutting surface 311 extends perpendicular to the rotation axis 11, and the second cutting surface 312 extends obliquely from the inside outward in a direction perpendicular to the rotation axis 11. The outer side of the second cutting surface 312 connects with the first cutting surface 311 to form a cutting edge. Because the overhanging housing 102 needs to be removed, the first cutting surface 311 facing the fixing frame 5 is a vertical plane perpendicular to the rotation axis 11 to ensure the flatness of the cut left by the conductive bar 10.

[0050] In this embodiment, the cutting device includes a positioning member 7, which is provided with a positioning surface 70 for abutting against the end of the conductive bar 10 to position the conductive bar 10. Specifically, the positioning surface 70 abuts against the end of the conductive bar 10 in a direction parallel to the rotation axis 11, thereby adjusting the position of the conductive bar 10 parallel to the axial direction of the rotation axis 11. In conjunction with the drive mechanism 1, which cannot move axially along the rotation axis 11, this ensures that the cutting direction does not deviate and that cutting is performed within a plane.

[0051] In this embodiment, the positioning member 7 has a first state and a second state. In the first state, the positioning surface 70 is located in the workspace and faces the fixed frame. In this mode, the position of the conductive bar 10 can be adjusted by driving the end of the conductive bar 10 against the positioning surface 70. In the second state, the positioning member 7 withdraws from the workspace to avoid affecting subsequent cutting operations. In this embodiment, the positioning member 7 is detachably connected to the fixed frame 5. When the conductive bar 10 needs to be positioned, the positioning member 7 is connected to the fixed frame 5. After positioning is completed, the positioning member 7 is detached from the fixed frame 5, so that the positioning member 7 is out of the workspace.

[0052] In this embodiment, the fixing frame 5 has an upward-facing support surface 51, with a fixing portion 52 disposed on one side of the support surface 51. Specifically, the fixing portion 52 is located on the side of the support surface 51 perpendicular to the axial direction of the rotation axis 11. When placing the conductive bar 10, the conductive bar 10 is placed on the support surface 51 and abutted against the fixing portion 52, thereby preliminarily positioning the conductive bar 10 in the vertical direction and perpendicular to the rotation axis 11. The conductive bar 10 is then moved in a direction parallel to the rotation axis 11 so that it abuts against the positioning surface 70, thereby achieving positioning parallel to the rotation axis 11.

[0053] In this embodiment, the fixing mechanism 6 includes a first fixing member 61 and a second fixing member 62. The first fixing member 61 is positioned above the support surface 51 and is movable up and down. The second fixing member 62 can be positioned relatively far from or relatively close to the fixing portion 52. The first fixing member 61 cooperates with the support surface 51 to fix the conductive bar 10 in the vertical direction. The second fixing member 62 cooperates with the fixing portion 52 to fix the conductive bar 10 in a direction perpendicular to the rotation axis 11.

[0054] In this embodiment, the fixing mechanism 6 includes a first toggle clamp 63 and a second toggle clamp 64. The first toggle clamp 63 drives the first fixing member 61 to move up and down, while the second toggle clamp 64 drives the second fixing member 62 to move axially perpendicular to the rotation axis 11. After the conductive bar 10 abuts against the positioning surface 70 and is positioned, the first toggle clamp 63 is operated to drive the first fixing member 61 downward to clamp the conductive bar 10, while the second toggle clamp 64 is operated to drive the second fixing member 62 toward the fixing portion 52 to clamp the conductive bar 10.

[0055] In other embodiments, the movement of the first and second fixing members 61, 62 is electrically controlled and driven, eliminating the need for manual operation by an operator. The cutting device is provided with a control system that controls the movement of the first and second fixing members 61, 62. Preferably, the cutting device is provided with a sensor that detects whether the end of the conductive bar 10 abuts the positioning surface 70. When the end of the conductive bar 10 abuts the positioning surface 70, the sensor sends a signal to the control system, thereby driving the first and second fixing members 61, 62 to clamp and secure the conductive bar 10. This allows for automated securing operations.

[0056] In this embodiment, see Figure 10 As shown, the positioning member 7 includes a connecting frame 71 and a positioning pin 72. In the first state, the connecting frame 71 is connected to the fixing frame 5. The positioning pin 72 is arranged on the connecting frame 71 parallel to the rotation axis 11. One side end surface of the positioning pin 72 constitutes a positioning surface 70. Specifically, the end surface of the positioning pin facing the fixing frame 5 constitutes the positioning surface 70. In some embodiments, the positioning pin 72 is adjustably arranged on the connecting frame 71 along its own length direction, so that the distance between the positioning surface 70 and the fixing frame 5 can be adjusted. In other embodiments, the positioning pin 72 is detachably connected to the connecting frame 71, and the distance between the positioning surface 70 and the fixing frame 5 can be adjusted by replacing the positioning pins 72 of different lengths. Specifically, see Figures 9 to 11 As shown, the connecting frame 71 is L-shaped, and has a positioning portion extending axially perpendicular to the rotation axis 11 in the first state and a connecting portion connected between the positioning portion and the fixing frame 5, and the connecting portion is detachably connected to the fixing frame 5.

[0057] In this embodiment, the cutting device includes a calibration member 8 having a calibration surface 81 for abutting against the cutting blade 3 along the axial direction of the rotating shaft 11 to position the cutting blade 3. The calibration surface 81 allows the cutting blade 3 to be positioned and adjusted. After adjustment, the cutting blade 3 is fixed so that it cannot move relative to the rotating shaft 11. The first and second limiting mechanisms cooperate to ensure that the cutting blade 3 cuts within a predetermined plane during the cutting process.

[0058] In this embodiment, the correction surface 81 and the positioning surface 70 of the positioning member 7 in the first state are spaced apart by a predetermined distance in a direction parallel to the axial direction of the rotation axis 11. The positioning surface 70 and the correction surface 81 cooperate to achieve positioning of the cutting position. By adjusting the position of the positioning surface 70, the cutting position of the conductive bar 10 can be changed.

[0059] In this embodiment, the correction member 8 includes two positioning plates 82 spaced apart and arranged axially parallel to the rotation axis 11. A positioning slot is formed between the two positioning plates 82. The side surface of one positioning plate 82 constitutes the slot wall of the positioning slot and also forms the correction surface 81. Specifically, the side surface of the positioning plate 82 facing away from the drive mechanism 1 constitutes the correction surface 81. When positioning or installing the cutting blade 3, the cutting blade 3 is inserted into the positioning slot so that the cutting blade 3 abuts the correction surface 81, and then the cutting blade 3 is fixed to the rotation axis 11. This arrangement simplifies the positioning and installation operations.

[0060] In this embodiment, the cutting device includes a frame 100, and the support frame 41, the fixing frame 5, and the correction member 8 are all arranged on the frame 100. In this embodiment, a control switch 110 is provided on the frame 100 for controlling the opening and closing of the driving mechanism 1.

[0061] In this embodiment, the drive mechanism 1 is manually driven to move. Specifically, a handrail 13 is provided on the side of the drive mechanism 1 away from the cutting blade 3, and the operator drives the drive mechanism 1 to move through the handrail 13. In this embodiment, the cutting device includes a crane 91, which is located above the drive mechanism 1. The crane 91 has a sling 911 that can be connected to the drive mechanism 1 and can lift the drive mechanism 1 upward. The crane 91 can lift the drive mechanism 1 upward to offset the gravity of the drive mechanism 1, thereby reducing the operating burden of the operator. In some embodiments, the drive mechanism 1 can be moved by electric drive, without the need for manual operation by the operator, thereby reducing the operating burden of the operator.

[0062] In this embodiment, the cutting device includes a protective cover 92. Protective cover 92 has a protective state. When in this state, protective cover 92 covers the circumferential outside of conductive bar 10. During the cutting operation, switching protective cover 92 to the protective state prevents waste chips from splashing during the cutting process, ensuring equipment cleanliness while also ensuring safety. Specifically, protective cover 92 is rotatably mounted on frame 100. By rotating protective cover 92, it can be moved to cover the outside of conductive bar 10, thereby switching to the protective state.

[0063] In this embodiment, the steps for cutting the outer shell 102 at the end of the conductive bar 10 are as follows: S1. Place the conductive bar 10 on the fixing frame 5, switch the positioning member 7 to the first state, and force one end of the conductive bar 10 to extend into the working space and abut against the positioning surface 70. Specifically, the positioning member 7 is connected to the fixing frame 5, and the conductive bar 10 is placed on the supporting surface 51 of the fixing frame 5 with one side of the conductive bar 10 abutting against the fixing portion 52. The end of the conductive bar 10 is forced to extend into the working space in an axial direction parallel to the rotation axis 11 and abut against the positioning surface 70, thereby achieving the positioning of the conductive bar 10.

[0064] S2. Use the fixing mechanism to fix the conductive bar 10. Specifically, drive the first fixing member 61 downward and drive the second fixing member 62 toward the fixing portion 52 to fix the conductive bar 10.

[0065] S3, driving the positioning member 7 out of the working space and switching to the second state. Specifically, the positioning member 7 is detached from the fixing frame 5.

[0066] S4. Start the driving mechanism 1, the rotating shaft 11 drives the cutting blade 3 to rotate, driving the abutting surface 21 of the guide block 2 to fit with the outer shell 102 of the conductive bar 10 and keep the abutting surface 21 and the outer shell 102 in a state of fitting, driving the driving mechanism 1 to move along the circumference of the conductive bar 10 and cut the outer shell 102 of the conductive bar 10 through the cutting portion 31.

[0067] Specifically, in step S4, the driving mechanism 1 moves one circle along the outer side of the conductive bar 10, thereby achieving an annular cut and removing the housing 102 in one go. Preferably, in step S4, the movement direction of the driving mechanism 1 is opposite to the rotation direction of the rotating shaft 11 to ensure the stability of the movement of the driving mechanism 1.

[0068] In this embodiment, preparatory work S01 is performed before step S1. Preparatory work S01 includes: driving the cutting blade 3 along the axial direction of the rotating shaft 11 to abut against the correction surface 81, and then securing the cutting blade 3 to the rotating shaft 11. Specifically, the cutting blade 3 is inserted into the positioning groove formed by the two positioning plates 82, and then the rotating shaft 11 and the cutting blade 3 are secured. When cutting multiple conductive bars 10 of the same type, preparatory work S01 only needs to be performed once, and then steps S1 and S2 need only be repeated. When cutting different types of conductive bars 10, the cutting position can be adjusted by adjusting the positioning surface 70, without having to perform preparatory work S01 again.

[0069] In summary, the conductive bar shell cutting device of this embodiment drives the abutment surface 21 of the guide block 2 to contact the outer surface of the conductive bar 10 shell 102 during the cutting operation, maintaining the abutment surface 21 in contact with the outer surface 102 of the conductive bar 10. The drive mechanism 1 is then driven to move circumferentially around the conductive bar 10, allowing the cutting blade 3 fixed to the rotating shaft 11 to cut the outer surface 102 of the conductive bar 10 circumferentially. The guide block 2 provides motion guidance for the drive mechanism 1 and a cutting path for the cutting blade 3 fixed to the rotating shaft 11. The distance from the abutment surface 21 to the centerline of the rotating shaft 11 is constant at all locations, thereby ensuring a consistent cutting depth for the cutting blade 3. The conductive bar 10 does not require adjustment during the cutting process, and the entire cutting operation can be completed in one go, improving cutting efficiency and yield. The cutting device also exhibits high adaptability, capable of cutting conductive bars 10 of varying sizes and cross-sectional shapes.
