Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to an integrated equipment for beveling and welding. Background Technology

[0002] Currently, transformer windings are mostly made of single or multiple conductors, and the connection between windings and the transmission of electrical energy are completed by welding the conductors. In existing technology, it is usually necessary to pre-make bevels at the ends of the conductors before welding. This method can effectively improve the structural strength and conductivity of the welded part by increasing the welding contact area.

[0003] Beveling usually requires operators to use files or grinding wheels to grind the ends of the wires to form a specific angled cut surface; welding usually requires operators to use tools such as manual vises to clamp the ends of the wires, align the bevels of the two wires, and then weld them.

[0004] However, manual grinding of beveling is inefficient and produces poor angle consistency, easily leading to mismatched welding contact surfaces; manual clamping makes it difficult to ensure the beveling surface fit accuracy, easily resulting in incomplete welds or misalignment defects during welding; and the separation of beveling and welding processes is cumbersome and loosely connected, seriously affecting welding yield and production efficiency. Therefore, there is an urgent need for an integrated device that can automatically complete beveling and simultaneously perform stable welding on the beveled surface. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the deficiencies and defects mentioned in the background art above, and to provide an integrated equipment for beveling and welding coil winding conductors with high beveling accuracy, good welding quality, tight process connection, simple operation, high efficiency and strong safety.

[0006] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0007] An integrated equipment for beveling and welding coil winding conductors includes a machine body, on which a beveling device and a welding device are disposed on one side of the beveling device. The beveling device includes a beveling clamping assembly for clamping the conductor for beveling, and a cutting tool assembly mounted above the beveling clamping assembly for beveling the conductor. The welding device includes a first welding clamping member and a second welding clamping member for clamping the conductor with two bevel surfaces in contact for welding.

[0008] In the aforementioned integrated equipment for beveling and welding coil winding conductors, preferably, the tool assembly is mounted on the machine body and can be moved up and down via a first lifting drive assembly. The tool assembly includes a rotating cutter head positioned above the beveling clamping assembly, a spindle motor driving the rotating cutter head, and a tool holder. The spindle motor is positioned above the tool holder, and the rotating cutter head is positioned below the tool holder. The rotating cutter head, driven by the spindle motor, grinds the end of the conductor. Furthermore, the first lifting drive assembly allows the rotating cutter head to be precisely positioned according to the actual cutting depth of the workpiece, thereby achieving precise beveling and enabling the equipment to flexibly adapt to beveling coil winding conductors of different sizes and specifications.

[0009] In the aforementioned integrated equipment for beveling and welding coil winding conductors, preferably, the first lifting drive assembly includes a linear guide rail vertically mounted on the machine body and a slider matching the linear guide rail, with the tool holder connected to the slider. The combination of the linear guide rail and the slider provides high-precision linear motion. During the lifting and lowering of the tool assembly, the slider slides smoothly along the linear guide rail, ensuring accurate vertical movement trajectories of the tool holder and the tool assembly. This effectively avoids machining errors caused by tool position deviation, thereby guaranteeing the consistency and stability of the beveling quality.

[0010] In the aforementioned integrated equipment for beveling and welding coil winding conductors, preferably, the beveling clamping assembly includes a clamping and fixing seat for placing the conductor, and an adjustable clamping mechanism disposed on the clamping and fixing seat for clamping the conductor. The top surface of the clamping and fixing seat is inclined, with its highest point located directly below the rotating cutter head. The adjustable clamping mechanism can be adjusted according to the conductor specifications to ensure that the conductor is securely fixed during processing, avoiding processing errors caused by conductor movement. The inclined top surface of the clamping and fixing seat ensures that the end of the conductor placed on it is exactly at its highest point, forming a certain angle with the rotating cutter head directly above, ensuring that the rotating cutter head can accurately bevele the conductor.

[0011] In the aforementioned integrated equipment for beveling and welding coil winding conductors, preferably, the adjustable clamping mechanism includes a movable jaw, a fixed jaw opposite to the movable jaw, and a rotary handle for moving the movable jaw closer to or away from the fixed jaw. The rotary handle is located on the side of the fixed jaw. The rotary handle simplifies the clamping operation, allowing the operator to quickly move the movable jaw closer to or away from the conductor by simply rotating the handle.

[0012] Preferably, the aforementioned integrated equipment for beveling and welding coil winding conductors further includes a limiting device for controlling the processing depth of the conductors. This limiting device includes a lower limiting member vertically mounted on one side of the beveling clamping assembly and adjustable up and down, and an upper limiting member vertically mounted on the tool assembly corresponding to the lower limiting member. The upper limiting member moves up and down with the tool assembly, while the lower limiting member blocks the downward movement of the upper limiting member. Through the cooperation of the upper and lower limiting members, the downward movement distance of the tool assembly can be precisely controlled, thereby accurately determining the beveling depth and ensuring consistent beveling depth for each conductor, improving the consistency and stability of processing quality. Furthermore, the lower limiting member can be flexibly adjusted up and down according to different conductor specifications and processing requirements, allowing operators to quickly set a suitable processing depth based on actual conditions, thus improving the adaptability of the equipment.

[0013] Preferably, the aforementioned integrated equipment for beveling and welding coil winding conductors further includes a protective cover surrounding the beveling device, and a second lifting drive assembly for driving the protective cover to move up and down. A flexible protective curtain is provided on the conductor entry side of the protective cover. The protective cover effectively blocks debris generated during the beveling process, preventing injury to operators. The second lifting drive assembly allows the protective cover to move up and down, flexibly adjusting its height. The flexible protective curtain adapts to conductors of different diameters and shapes, naturally separating when the conductor enters or exits without causing obstruction or damage, and forming a certain sealing effect upon contact with the conductor.

[0014] In the aforementioned integrated equipment for beveling and welding coil winding conductors, preferably, a debris collection chamber is provided inside the machine body below the beveling clamping assembly, and a collection hole is provided at the upper end of the debris collection chamber for collecting debris generated during beveling. This design ensures that debris generated during beveling falls into the debris collection chamber through the collection hole, preventing debris from scattering on and around the equipment surface, keeping the equipment clean, and reducing cleaning workload.

[0015] In the aforementioned integrated equipment for beveling and welding coil winding conductors, preferably, the first welding clamp and the second welding clamp are horizontally spaced and coaxially arranged, and a sloping guide surface is provided in the space between the first welding clamp and the second welding clamp, the sloping guide surface being connected to the debris collection cavity. The horizontally spaced and coaxial arrangement of the first and second welding clamps ensures the alignment and coaxiality of the conductors during the welding process, thereby improving welding quality and ensuring the uniformity and consistency of the weld. The sloping guide surface effectively guides the debris generated during welding to the debris collection cavity, preventing debris accumulation in the welding area and reducing interference with the welding process and contamination of the equipment.

[0016] In the aforementioned integrated equipment for beveling and welding coil winding conductors, preferably, a dust-blowing and suction component is suspended on one side of the tool assembly. This dust-blowing and suction component can promptly remove dust and debris from the beveling area, maintaining its cleanliness, reducing processing errors caused by dust interference, and improving the accuracy and quality of the beveling process.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This utility model integrates beveling and welding processes, using a tool assembly to standardize beveling angles. Combined with the synergistic effect of welding clamps, it achieves tight process connections, reduces manual intervention, and precisely ensures beveling accuracy and beveling face alignment stability. This significantly improves the processing efficiency and welding quality of winding conductors, enhances the consistency of coil winding welding quality, improves coil resistance performance, and ultimately achieves a continuous and efficient production mode, comprehensively enhancing process reliability and product yield.
