Description

Technical Field

[0001] This utility model relates to the technical field of copper busbar processing equipment, and in particular to a multi-angle sawing mechanism for irregularly shaped copper busbars. Background Technology

[0002] Copper busbars, as key conductive and structural components in power systems, electronic equipment, and machinery manufacturing, exhibit diverse forms depending on application requirements. Among them, irregularly shaped copper busbars, with specific cross-sectional shapes such as L-shaped, T-shaped, channel-shaped, and custom-designed irregular shapes, can adapt to complex assembly spaces, optimize current distribution, or enhance structural support strength, leading to their increasingly widespread application in high-end power distribution equipment, new energy vehicle power battery packs, and precision electronic instruments.

[0003] Sawing is one of the core processes in the production and application of irregular-shaped copper busbars. Its purpose is to cut long strips of copper busbar blanks into finished segments that meet the design dimensions, or to trim and bevele the ends of finished copper busbars to meet subsequent assembly and docking requirements. Existing copper busbar sawing mechanisms are mostly designed for conventional rectangular copper busbars, and their sawing angle adjustment capabilities are limited. Most can only achieve 90° vertical sawing, which cannot meet the processing requirements of irregular-shaped copper busbars, such as beveling and angle cutting, due to assembly angle requirements. If manual adjustment is used, it is not only inefficient, but also difficult to guarantee angle accuracy. Moreover, the irregular cross-section of irregular-shaped copper busbars makes it impossible for traditional planar clamping structures to form effective positioning. During the sawing process, copper busbars are prone to displacement and vibration, which in turn leads to quality problems such as chipped edges and out-of-tolerance dimensions.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Reference Figure 1 This embodiment provides a multi-angle sawing mechanism for irregularly shaped copper busbars, including a base 1, a multi-directional angle adjustment component 2, a sawing component 3, a positioning and clamping component 4, and a control unit. The base 1 serves as the mounting foundation and load-bearing platform for the entire mechanism, providing stable assembly support for each functional component. Its material can be high-strength cast iron or aluminum alloy, ensuring structural rigidity to resist vibration and impact during sawing while controlling the overall weight according to application requirements. The multi-directional angle adjustment component 2, sawing component 3, and positioning and clamping component 4 are all mounted on the base 1. The installation positions of each component are rationally arranged according to the sawing process flow to ensure coordinated operation of the sawing and positioning / clamping actions. The multi-directional angle adjustment component 2 is drively connected to the sawing component 3, driving the sawing component 3 to rotate around a preset axis to achieve multi-angle sawing adjustment. This preset axis can be set along the length of the base 1 according to processing requirements. The axis extends in the directional direction, width direction, or is at a certain angle to the horizontal plane. It can be rotated to achieve sawing at any angle within the range of 0°-90°, or can be extended to negative angle adjustment, thereby meeting diverse processing needs such as beveling and angled beveling of irregular copper busbars. The positioning and clamping component 4 is equipped with a positioning structure and adjustable clamping structure that can adapt to L-shaped, T-shaped, slotted, and various custom-shaped irregular copper busbars. Precise positioning and reliable clamping prevent the copper busbar from shifting or vibrating during the sawing process. The control unit adopts a control core such as a PLC controller, microcontroller, or industrial computer. It is connected to the multi-directional angle adjustment component 2, sawing component 3, and positioning and clamping component 4 through wires or wireless communication modules. It can preset the processing parameters of irregular copper busbars of different specifications, realize the automated control of sawing angle adjustment, sawing action execution, and clamping and positioning operations, and improve processing efficiency and operation accuracy.

[0020] Specifically, refer to Figure 2The multi-directional angle adjustment assembly 2 includes a rotary drive 21, a rotary shaft 22, and an angle positioning component 23. The rotary shaft 22 is rotatably mounted on the base 1 via a bearing housing. The bearing housing can be a deep groove ball bearing or a tapered roller bearing to ensure the smooth rotation of the rotary shaft 22 and to withstand radial and axial loads. The sawing assembly 3 is fixedly connected to the rotary shaft 22 via a flange, key connection, or welding, ensuring that the rotary shaft 22 can synchronously drive the sawing assembly 3 to adjust its angle when rotating. The rotary drive 21 is drive-connected to the rotary shaft 22 and can be selected from... A servo motor, stepper motor, or hydraulic motor transmits power to the rotating shaft 22 to achieve precise angle adjustment of the sawing assembly 3. The angle positioning component 23 is used to position and lock the rotation angle of the rotating shaft 22. It can adopt an electromagnetic positioning structure, which uses the magnetic force generated by the electromagnet to attract the positioning block on the rotating shaft 22 to achieve positioning. The rotating drive component 21 provides power to drive the sawing assembly 3 to rotate and adjust the angle. The angle positioning component 23 ensures the stability of the sawing assembly 3 at the target angle position, which can improve the accuracy and reliability of angle adjustment.

[0021] Furthermore, the multi-directional angle adjustment assembly 2 also includes an angle limiting component 24, which is disposed on the base 1 and located on both sides of the rotating shaft 22. It can be a limiting block, a limiting bolt, or a limit switch. When a limiting block is used, a metal limiting block can be welded or bolted to the base 1 at the rotation limit position corresponding to the rotating shaft 22. A rubber buffer pad can be attached to the surface of the limiting block to reduce impact. When a limiting bolt is used, an elongated adjustment hole can be opened on the base 1, through which the limiting bolt is passed and fixed with a nut. The rotation limit of the rotating shaft 22 can be flexibly changed by adjusting the position of the limiting bolt. When using a limit switch, a trigger lug can be set on the rotating shaft 22, and a limit switch can be installed at the corresponding position on the base 1. When the rotating shaft 22 rotates to the limit angle, the trigger lug touches the limit switch, and the limit switch sends a signal to the control unit. The control unit controls the rotating drive component 21 to stop working, thereby realizing electrical limit protection. The setting of the angle limit component 24 can effectively limit the rotation range of the rotating shaft 22, avoiding excessive rotation angle of the sawing component 3 due to operational errors or equipment failure, which could cause collision damage with other components on the base 1. This provides a safety guarantee for equipment operation and further improves the safety and reliability of the mechanism.

[0022] Furthermore, the multi-directional angle adjustment component 2 also includes an angle detection element 25, which is mounted on the rotating shaft 22. This element can be an encoder, an angle sensor, or a potentiometer. When an encoder is used, an incremental encoder or an absolute encoder can be employed, directly connected to the rotating shaft 22 via a coupling. The rotation of the rotating shaft 22 drives the encoder to rotate, and the encoder converts the rotation angle into an electrical signal, which is then transmitted to the control unit. When an angle sensor is used, a Hall effect angle sensor or a photoelectric angle sensor can be employed, obtaining angle information by detecting changes in the position of a magnet or light-shielding plate on the rotating shaft 22. When a potentiometer is used, the potentiometer's shaft rotates synchronously with the rotating shaft 22, and the change in the potentiometer's output voltage reflects the rotation angle. The angle detection element 25 can detect the actual rotation angle of the sawing component 3 in real time and feed the detection signal back to the control unit. The control unit compares the actual angle with the preset angle. If a deviation exists, it controls the rotating drive component 21 to correct it, forming a closed-loop control. This ensures that the actual sawing angle is highly consistent with the design requirements, further improving the accuracy of angle adjustment and meeting the high-precision processing needs of irregularly shaped copper busbars.

[0023] The sawing assembly 3 includes a saw blade 31, a saw blade drive 32, and a sawing feed 33. The saw blade 31 can be a high-speed steel saw blade, a carbide saw blade, or a diamond saw blade, and the appropriate saw blade type can be selected based on the material hardness and processing quality requirements of the irregularly shaped copper busbar. The output end of the saw blade drive 32 is fixedly connected to the saw blade 31 via a flange, a saw blade shaft, and a locking nut. It can be powered by a motor, which can drive the saw blade 31 to rotate at high speed via direct drive or belt drive, providing cutting power for the sawing process. The output end of the sawing feed 33... Fixedly connected to the saw blade drive 32, the feed speed and pressure of the saw blade 31 can be adjusted according to the cross-sectional characteristics of the irregular copper busbar. For example, for irregular copper busbars with large cross-sectional dimensions, the feed speed can be reduced and the feed pressure increased to ensure a smooth sawing process; for thin-walled or easily deformable irregular copper busbars, the feed speed can be increased and the feed pressure reduced to avoid chipping of the cut edge or deformation of the copper busbar. The saw blade drive 32 provides cutting power, and the feed parameters can be flexibly adjusted by the sawing feed 33 to achieve adaptive sawing, improve cut quality and sawing efficiency.

[0024] The sawing feed component 33 includes a feed guide rail 331, a feed slider 332, a feed drive component 333, and a pressure sensor 334. The feed guide rail 331 is fixedly mounted on the mounting plate of the multi-directional angle adjustment assembly 2. It can be a linear guide rail, a dovetail guide rail, or a cylindrical guide rail, selected according to the precision requirements and cost budget of the mechanism. The feed slider 332 slides with the feed guide rail 331, and ball bearings or sliding bearings can be installed between them to reduce frictional resistance. The saw blade drive component 32 is fixed on the feed slider 332, ensuring that the feed slider 332 moves synchronously, driving the saw blade drive component 32 and the saw blade 31 to feed simultaneously. The output end of the feed drive component 333 is connected to the feed slider 332 via a ball screw drive mechanism, a gear and rack drive mechanism, or a cylinder drive mechanism, driving the feed slider 332 to move along the guide rail, achieving precise control of the feed speed and feed amount. The pressure sensor 334... Sensor 334 is located at the connection between saw blade drive 32 and feed slider 332. It can be a strain gauge pressure sensor or a piezoelectric pressure sensor. It can detect the sawing pressure borne by saw blade 31 in real time during sawing and transmit the pressure signal to the control unit. The control unit automatically adjusts the output of feed drive 333 according to the pressure signal. For example, when the pressure is too high, the feed speed or feed pressure is reduced to avoid damage to the saw blade; when the pressure is too low, the feed speed is increased to improve processing efficiency. This structure can ensure the smoothness of feed movement through the cooperation of feed guide rail 331 and feed slider 332, realize the drive of feed action through feed drive 333, and realize real-time monitoring of sawing pressure and dynamic adjustment of feed parameters through pressure sensor 334, so that the feed parameters are always adapted to the current sawing state, further improving the stability of sawing process and cut quality.

[0025] Reference Figure 3The positioning and clamping assembly 4 includes a positioning seat 41, a movable clamping member 42, a clamping drive member 43, and an adjustable lateral positioning member 44. The positioning seat 41 is fixed to the base 1, and its top has an installation groove. A replaceable positioning groove module 411 is embedded in the installation groove. The positioning groove module 411 can be made of aluminum alloy, engineering plastic, or cast iron. The surface of the positioning groove module 411 has a positioning groove 4111 adapted to the cross-sectional shape of the irregular copper busbar. For irregular copper busbars with different cross-sections, precise positioning can be achieved simply by replacing the corresponding specification of the positioning groove module 411. The movable clamping member 42 is movably mounted on the positioning seat 41 via a guide rail slider or guide hole. Its clamping end can be designed as a flat, arc-shaped, or irregularly shaped structure adapted to the surface of the copper busbar, depending on the shape of the positioning groove 4111, to increase clamping force. The contact area is increased to improve clamping stability. The output end of the clamping drive 43 is fixedly connected to the movable clamping member 42, which can be a cylinder, hydraulic cylinder or electric push rod, to drive the movable clamping member 42 to move toward the positioning groove 4111 to achieve clamping. The adjustable lateral positioning member 44 is set on the positioning seat 41 along the side of the positioning groove 4111. It can adopt a bolt tightening structure, an eccentric wheel positioning structure or a spring clip positioning structure to press its edge against the positioning groove module 411 to achieve fixation. This structure adapts to irregularly shaped copper busbars with different cross sections through the replaceable positioning groove module 411, and achieves reliable clamping through the movable clamping member 42 and the clamping drive 43. The adjustable lateral positioning member 44 ensures the stability of the positioning groove module 411 installation and avoids quality defects caused by copper busbar displacement and vibration during the sawing process.

[0026] Furthermore, an elastic buffer layer 4112 is provided on the inner wall of the positioning groove 4111. The elastic buffer layer 4112 can be made of rubber, silicone or polyurethane material and is fixed to the inner wall of the positioning groove 4111 by bonding or embedding. The elastic buffer layer 4112 has a certain elastic deformation capability. When the irregular copper busbar is inserted into the positioning groove 4111 and clamped, the elastic buffer layer 4112 can conform to the irregular shape of the copper busbar surface, increase the contact friction, and improve the stability of positioning and clamping. At the same time, it can absorb some of the vibration energy generated during the sawing process and reduce the impact of vibration on the positioning of the copper busbar. In addition, the elastic material can also prevent the inner wall of the positioning groove 4111 from directly and rigidly contacting the surface of the copper busbar, preventing the surface of the copper busbar from being scratched or crushed, and playing a role in protecting the surface quality of the copper busbar.
