Description

A leveling and calibration welding head for a flow battery product Technical Field

[0001] This utility model relates to the field of automated welding, and in particular to a leveling and calibration welding head for flow battery products. Background Technology

[0002] When automating the welding of flow battery products, welding heads attached to robotic arms are typically used. A special type of welding head has recently emerged on the market. This head features multiple collinear welding points, enabling multi-point welding operations in a single operation. Compared to traditional welding heads with only one welding point, this type of head requires strict precision in its relative position to the robotic arm during installation (specifically, the lines containing the multiple welding points must be perpendicular to the central axis of the robotic arm); otherwise, the welding result may be affected.

[0003] The traditional method is to use a flange structure to connect the welding head and the robotic arm. However, the flange structure still has certain limitations. When the flange itself has a precision problem, it cannot be adjusted.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0005] This invention addresses the aforementioned shortcomings of existing technologies by proposing a welding head that is simple in structure, ingeniously designed, rationally laid out, and capable of quickly, conveniently, and accurately adjusting (leveling) the positional accuracy between the welding head and the robotic arm.

[0006] The technical solution of this utility model is: a leveling and calibration welding head for flow battery products, comprising a welding head body 1, characterized in that: the top of the welding head body 1 is connected to an amplifier 2, the amplifier 2 has a protruding connecting skirt 3 in the middle, the outer edge of the connecting skirt 3 has a plurality of positioning notches 4 evenly distributed in the circumferential direction, and the connecting skirt 3 is clamped by an inner plate 5 below it and a pressure plate 6 above it, the inner plate 5 and the pressure plate 6 are fixed by pressure plate bolts 7, and a positioning pin 8 matching the positioning notches 4 is also provided inside the inner plate 5.

[0007] The inner plate 5 is located in a recessed groove at the center of the lower plate 9. Four leveling bolts 10, evenly distributed in a circumferential direction, are threaded onto the bottom surface of the lower plate 9, with the tops of the leveling bolts 10 contacting the bottom surface of the inner plate 5. An upper plate 11 is positioned above the pressure plate 6, and the upper plate 11 is fixedly connected to the lower plate 9 by upper plate bolts 12. In other words, the inner plate 5 and the pressure plate 6 are clamped together by the upper plate 11 above and the lower plate 9 below.

[0008] Both the upper plate 11 and the lower plate 9 have multiple bolt holes evenly distributed in the circumferential direction, and long connecting bolts 13 are connected to the bolt holes.

[0009] The inner plate 5, pressure plate 6, lower plate 9, and upper plate 11 are all provided with circular holes at their centers, allowing the amplifier 2 to pass through.

[0010] The pressure plate 6 is composed of two semi-annular components.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] This type of flow battery product uses a leveling and calibration welding head, which features a simple structure, ingenious design, and reasonable layout. Addressing the problems of traditional welding head and robotic arm connection structures, it employs a unique design. It uses a pressure plate and an inner plate to clamp the amplifier directly connected to the welding head body. An upper and lower plate further clamp the pressure plate and inner plate, forming an integrated structure. Multiple leveling bolts adjust the posture of the inner plate relative to the upper and lower plates. Because the lines connecting the inner plate and multiple welding points on the welding head body are parallel in space, adjusting the posture of the inner plate allows for adjustment of the welding head body. This enables quick, convenient, and precise connection and relative position adjustment between the welding head and the robotic arm, ensuring welding quality. Furthermore, its manufacturing process is simple and cost-effective. Therefore, it possesses numerous advantages and is particularly suitable for widespread application in this field, with a very broad market prospect. Attached Figure Description

[0014] Figure 2 is an exploded view of the parts in an embodiment of this utility model. Detailed Implementation

[0015] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. As shown in Figures 1 and 2: A leveling and calibration welding head for flow battery products includes a welding head body 1. The top of the welding head body 1 is connected to an amplifier 2. The amplifier 2 has a protruding connecting skirt 3 in the middle. The outer edge of the connecting skirt 3 has a plurality of positioning notches 4 evenly distributed in the circumferential direction. The connecting skirt 3 is clamped by an inner plate 5 below it and a pressure plate 6 above it. The inner plate 5 and the pressure plate 6 are fixed together by pressure plate bolts 7. At the same time, a positioning pin 8 matching the positioning notch 4 is also provided inside the inner plate 5.

[0016] The inner plate 5 is located in a recessed groove at the center of the lower plate 9. Four leveling bolts 10, evenly distributed in a circumferential direction, are threaded onto the bottom surface of the lower plate 9, with the tops of the leveling bolts 10 contacting the bottom surface of the inner plate 5. An upper plate 11 is positioned above the pressure plate 6, and the upper plate 11 is fixedly connected to the lower plate 9 by upper plate bolts 12. In other words, the inner plate 5 and the pressure plate 6 are clamped together by the upper plate 11 above and the lower plate 9 below.

[0017] Both the upper plate 11 and the lower plate 9 have multiple bolt holes evenly distributed in the circumferential direction, and long connecting bolts 13 are connected to the bolt holes.

[0018] The inner plate 5, pressure plate 6, lower plate 9, and upper plate 11 are all provided with circular holes at their centers, allowing the amplifier 2 to pass through.

[0019] The pressure plate 6 is composed of two semi-annular components.

[0020] The working process of the leveling and calibration welding head for the flow battery product of this utility model embodiment is as follows: During installation, firstly, the amplifier 2 is inserted into the center hole on the inner plate 5, ensuring that a certain positioning notch 4 on the outer edge of the connecting skirt 3 is engaged with the positioning pin 8 on the inner plate 5. Then, the two semi-annular components are pressed together above the connecting skirt 3, and the inner plate 5 is connected to the pressure plate 6 using the pressure plate bolt 7. At this time, the amplifier 2 is clamped and fixed by the inner plate 5 and the pressure plate 6.

[0021] The inner plate 5 and the pressure plate 6, which are connected as a single unit, are placed into the recessed groove in the center of the lower plate 9, and the upper plate 11 is fastened on top of it. Then, the upper plate 11 and the lower plate 9 are connected as a single unit using the upper plate bolts 12.

[0022] Then, the upper plate 11 / lower plate 9 is fixedly connected to the robotic arm using long connecting bolts 13. Since the welding head body 1 is fixedly connected to the amplifier 2, the connection between the robotic arm and the welding head body 1 is realized.

[0023] Since the inner plate 5 and the pressure plate 6, and the upper plate 11 and the lower plate 9 are essentially flange structures, the accuracy of assembly can be effectively guaranteed. Even if an angle is found between the central axis of the amplifier 2 and the central axis of the robotic arm after installation, it can be adjusted by the leveling bolt 10.

[0024] During adjustment, the staff rotates a leveling bolt 10, and the end of the leveling bolt 10 pushes the inner plate 5. By adjusting different leveling bolts 10, the posture of the inner plate 5 between the upper plate 11 and the lower plate 9 is changed. After adjustment, the result is verified by simulated welding. If the verification shows that the central axis of the amplifier 2 is coaxial with the central axis of the robotic arm, the adjustment is stopped. Otherwise, the adjustment continues until the two coincide.
