Description

Technical Field

[0001] This utility model relates to the technical field of busbar processing equipment, and more specifically to a busbar weld milling machine. Background Technology

[0002] A busbar is a conductive component used in electrical engineering to distribute current, typically made of copper or aluminum. Its function is to connect electrical equipment such as substations, distribution cabinets, and switchgear, carrying high-current transmission. Busbars are widely used in high-voltage and low-voltage power distribution systems and are one of the most important power distribution and transmission devices.

[0003] A busbar weld milling machine is a device specifically designed for milling busbar welds. It is commonly used in the electrical and electronics industries, especially in the production and processing of high-current busbars. Its purpose is to improve the surface quality of the busbar weld joints, remove welding defects, and ensure the surface quality and electrical contact performance of the busbar. Milling the welds not only improves the appearance of the busbar but also ensures good contact, reduces electrical contact resistance, and avoids electrical faults caused by uneven or defective welds.

[0004] Existing weld seam milling machines are prone to slippage and displacement when the workpiece is placed on the placement plate during the processing of welded busbars. The tail end of the workpiece is also prone to bending. Furthermore, the milling process generates flying debris, which not only contaminates the worktable and is difficult and time-consuming to clean, but also has a very adverse effect on the health of workers, reducing processing efficiency. To address these issues, we propose a busbar weld seam milling machine. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing weld seam milling machines, where the workpiece slides and shifts when placed on the placement plate after welding, the tail end of the workpiece is prone to bending, and the milling process generates waste chips that fly up during milling, causing table contamination, making cleaning inconvenient, time-consuming and labor-intensive, and reducing processing efficiency. Therefore, this utility model provides a busbar weld seam milling machine.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

A milling mechanism 17 is fixedly installed inside the chassis 1. A lifting assembly 5 is provided on the other side of the top of the chassis 1. A cutting waste box 7 is provided on one side of the bottom of the chassis 1.

[0023] In this embodiment, during use, after powering on, press and hold the reset button to return the milling cutter 1706 to its original position, and the pressure plate 3 is in the raised state. Then, place the welded busbar on the workpiece support plate 13, with the front end of the busbar close to the positioning block 19, so that the center position of the weld seam of the busbar roughly coincides with the center line of the milling cutter 1706. Then, by pressing the foot switch, the clamping cylinder 2 drives the pressure plate 3 to descend and clamp the workpiece. Afterwards, after setting the milling length on the touch screen of the operation box 4, press the start button to start the drive motor 1701. Through the transmission belt 1702, the drive motor 1701 drives the reciprocating screw 1703 to rotate, and the reciprocating screw 1703 drives the moving block 1704. The milling cutter 1706 moves horizontally, which in turn drives the milling cutter 1706 to move horizontally. Simultaneously, the rotary motor 1705 is started, which drives the milling cutter 1706 to rotate, thus starting the milling operation. The milling chips pass through the through slot 16 and enter the cutting waste box 7 through the machine housing 1, which facilitates the collection of chips and keeps the table clean, effectively preventing chip splashing and improving operational safety. After the milling is completed, the milling cutter 1706 returns to the original position and stops rotating. The red indicator light of the stop button flashes, indicating that the work is completed and the workpiece can be unloaded. Simply step on the foot switch, and the clamping cylinder 2 drives the pressure plate 3 to rise. After unloading the workpiece, load the next workpiece, and repeat the rising operation.

[0024] Furthermore, the milling mechanism 17 includes a drive motor 1701, a transmission belt 1702, and a reciprocating lead screw 1703, which are fixedly installed inside the housing 1. The output end of the drive motor 1701 is connected to the reciprocating lead screw 1703 via the transmission belt 1702. One end of the reciprocating lead screw 1703 is threadedly connected to a moving block 1704. A rotary motor 1705 is fixedly installed on one side of the moving block 1704. The output end of the rotary motor 1705 is fixedly connected to a milling cutter 1706. In use, by starting the drive motor 1701, the drive motor 1701 drives the reciprocating lead screw 1703 to rotate through the transmission belt 1702. The reciprocating lead screw 1703 drives the moving block 1704 to move horizontally, thereby driving the milling cutter 1706 to move horizontally. Simultaneously, by starting the rotary motor 1705, the rotary motor 1705 drives the milling cutter 1706 to rotate, thus starting the milling operation.

[0025] Furthermore, the lifting assembly 5 includes support side plates 51 symmetrically fixedly connected to the top two sides of the chassis 1. The top of the support side plates 51 is provided with several equally spaced placement grooves 53. A lifting roller 52 is provided between the two support side plates 51. In use, the position of the lifting roller 52 can be adjusted to avoid bending of the busbar, and it is convenient to process busbars of different sizes and lengths. It is flexible and adaptable. For busbars with larger lengths, an auxiliary lifting bracket needs to be added.

[0026] Furthermore, an electrical control cabinet door 6 is provided on one side of the chassis 1, and a tool maintenance cabinet door 10 is provided on the other side of the chassis 1. The tool maintenance cabinet door 10 and the through slot 16 facilitate maintenance operations.

[0027] Furthermore, a power switch 11 is located on the top of one side of the front of the chassis 1, an emergency stop switch 12 is located on one side of the top of the chassis 1, and a compressed air interface 14 is located inside the back of the chassis 1. In use, the emergency stop switch 12 is located to the lower right of the operator. In an emergency, pressing this button will stop the motor, keep the clamping cylinder 2 stationary, and disable the foot switch and all action buttons. Through the compressed air interface 14, compressed air can be used as a cooling medium, directly blowing onto the cutting tool and the machining surface to help dissipate heat, keep the machining temperature within a reasonable range, and prevent overheating damage to the end mill 1706 or the busbar surface. By periodically blowing away the metal chips accumulated on the surface of the end mill 1706 and the workpiece, compressed air helps reduce the direct contact between the end mill 1706 and the chips, avoids the re-cutting of metal chips, improves the durability of the end mill 1706, and extends its service life.

[0028] Furthermore, two workpiece support plates 13 are symmetrically distributed on both sides of the through slot 16. The milling cutter 1706 extends to the outside through the through slot 16. A positioning block 19 is fixedly connected to one side of the workpiece support plate 13, and a protective cover 18 is fixedly connected to the other side of the positioning block 19. The protective cover 18 is fixed to the top of the operating table 15. The cutting waste box 7 is connected to the bottom of the machine box 1. In use, the protective cover 18 can protect the milling cutter 1706.

[0029] The working principle of this utility model is as follows: Upon powering on, press and hold the reset button to return the milling cutter 1706 to its original position, with the pressure plate 3 in the raised state. Then, place the welded busbar on the workpiece support plate 13, with the front end of the busbar against the positioning block 19, ensuring the center of the busbar's weld seam roughly coincides with the centerline of the milling cutter 1706. Next, press the foot switch to activate the clamping cylinder 2, which lowers the pressure plate 3 to clamp the workpiece. After setting the milling length on the touchscreen of the control box 4, press the start button to start the drive motor 1701. Through the transmission belt 1702, the drive motor... 1701 drives the reciprocating lead screw 1703 to rotate, which in turn drives the moving block 1704 to move horizontally, thereby driving the milling cutter 1706 to move horizontally. Simultaneously, the rotary motor 1705 is started, which drives the milling cutter 1706 to rotate, thus starting the milling operation. After the milling is completed, the milling cutter 1706 returns to the original position and stops rotating. The red indicator light of the stop button flashes, indicating that the work is completed and the workpiece can be unloaded. Simply step on the foot switch, and the clamping cylinder 2 will drive the pressure plate 3 to rise. After unloading the workpiece, the next workpiece will be loaded, and the above operation can be repeated.
