Abstract
Description
Technical Field
[0001] This application relates to the field of sheet metal production equipment technology, and in particular to a positioning fixture for welding sheet metal parts. Background Technology
[0002] In modern industrial production, sheet metal parts are widely used in the automotive, aerospace, and home appliance industries due to their lightweight, high strength, and excellent machinability. Especially in the welding of sheet metal parts, positioning fixtures are crucial tools for ensuring welding accuracy and efficiency. However, existing positioning fixtures for sheet metal welding have significant functional limitations. These fixtures typically only provide simple clamping and fixing of workpieces, making it difficult to meet the processing needs of complex sheet metal parts, particularly when it is necessary to roll sheet metal parts into cylindrical structures and precisely fix their welds.
[0003] However, when operators roll sheet metal parts into cylindrical structures and fix their welds, additional manual assistance is required, which increases the difficulty of operation and time costs. Secondly, since the welds cannot be effectively fixed, deformation or misalignment is prone to occur during the welding process, which directly affects the welding quality. Therefore, a positioning fixture for welding sheet metal parts is proposed. Utility Model Content
[0004] To address the issue that additional manual assistance is required when operators roll sheet metal parts into cylindrical structures and fix their welds, which increases the difficulty and time cost of operation, this application provides a positioning fixture for welding sheet metal parts.
[0005] The positioning fixture for welding sheet metal parts provided in this application adopts the following technical solution:
[0006] A positioning fixture for welding sheet metal parts includes a base, a vertical plate fixedly connected to the upper surface of the base, a motor fixedly mounted on the surface of the vertical plate, the output shaft of the motor passing through the vertical plate and fixedly connected to a mold roller, a positioning mechanism provided on the mold roller, the positioning mechanism being able to fix one welding edge of the sheet metal part to the surface of the mold roller, a connecting plate fixedly connected to the top of the vertical plate, an electric push rod fixedly connected to the connecting plate, an arc-shaped plate fixedly connected to the telescopic end of the electric push rod, the arc-shaped plate being adapted to the curvature of the mold roller.
[0007] Preferably, the extension and retraction direction of the electric push rod is set along the radial direction of the mold roller.
[0008] Preferably, the positioning mechanism includes a positioning plate, a screw is inserted into one side of the mold roller, an insertion hole is opened on one side of the positioning plate, the shank of the screw passes through the insertion hole, the head diameter of the screw is larger than the diameter of the insertion hole, and the shank diameter is smaller than the diameter of the insertion hole.
[0009] Preferably, a guide rod is fixedly connected to the surface of the mold roller. The guide rod is configured as a T-shaped structure. The guide rod passes through the positioning plate and slides with it. A spring is sleeved on the surface of the guide rod. One end of the spring is fixedly connected to the end of the guide rod, and the other end of the spring is fixedly connected to the positioning plate.
[0010] Preferably, when the screw is tightened, the positioning plate contacts the surface of the mold roller, and the spring is in a stretched state.
[0011] In summary, this application includes the following beneficial technical effects:
[0012] This application utilizes a positioning mechanism to fix one welded edge of a sheet metal part onto the surface of a mold roller. By setting an arc plate in conjunction with an electric push rod, the sheet metal part undergoes corresponding deformation. Then, a motor drives the mold roller and the positioning mechanism to rotate, causing the sheet metal part to pass between the arc plate and the mold roller and to be wound around the sheet metal part. When the two welded edges of the sheet metal part are aligned, the electric push rod drives the arc plate to press the other welded edge of the sheet metal part, so that the workers can fix the sheet metal part.

[0019] Furthermore, the extension and retraction direction of the electric push rod 5 is set radially along the mold roller 2.
[0020] In this embodiment, a positioning mechanism is used to fix one welded edge of the sheet metal part onto the surface of the mold roller 2, and the electric push rod 5 is driven to move the arc plate 6 to one side of the mold roller 2, causing the sheet metal part to undergo corresponding deformation. Then, the motor 7 is used to drive the mold roller 2 and the positioning mechanism to rotate, causing the sheet metal part to pass between the arc plate 6 and the mold roller 2 and be wound around the sheet metal part. When the two welded edges of the sheet metal part are aligned, the electric push rod 5 is used to drive the arc plate 6 to press the other welded edge of the sheet metal part, so that the workers can fix the sheet metal part.
[0021] Furthermore, the positioning mechanism includes a positioning plate 11, a screw 10 is inserted into one side of the mold roller 2, and an insertion hole is opened on one side of the positioning plate 11. The rod of the screw 10 passes through the insertion hole, the diameter of the head of the screw 10 is larger than the diameter of the insertion hole, and the diameter of the rod of the screw 10 is smaller than the diameter of the insertion hole.
[0022] Furthermore, a guide rod 8 is fixedly connected to the surface of the mold roller 2. The guide rod 8 is configured as a T-shaped structure. The guide rod 8 passes through the positioning plate 11 and slides with it. A spring 9 is sleeved on the surface of the guide rod 8. One end of the spring 9 is fixedly connected to the end of the guide rod 8, and the other end of the spring 9 is fixedly connected to the positioning plate 11.

[0024] In this embodiment, one welded edge of the sheet metal part is placed between the mold roller 2 and the positioning plate 11, and then the screw 10 is tightened so that the positioning plate 11 presses the sheet metal part to fix it. After the sheet metal part is welded, the screw 10 is tightened, the stretched spring 9 is reset, and the positioning plate 11 is reset so that the positioning plate 11 is away from the sheet metal part and no longer clamps the sheet metal part, so that the sheet metal part can be removed from the mold roller 2.
