Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, and specifically relates to a novel tooling for dual-station welding of high-elasticity couplings. Background Technology

[0002] Flexible gear couplings are generally composed of internal gear rings with the same number of teeth and flanged half-couplings with external teeth. They are commonly used in shaft transmission under low-speed and heavy-load conditions, such as in the metallurgical, mining, and hoisting and transportation industries. They are also suitable for industries such as petroleum, chemical, and general machinery. The welding of the ring plate and the gear ring is a processing technology.

[0003] Traditional welding methods typically use simple support fixtures to fix the workpiece, and then welders or welding robots perform continuous circumferential welding. Continuous welding can cause large welding stress inside the workpiece, which can lead to workpiece deformation and seriously affect the dimensional accuracy and performance of the product. Single-station operation means that the loading and unloading time and welding time cannot overlap, thereby reducing production efficiency. To solve the above problems, we provide a new type of high-elasticity coupling dual-station welding fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a novel high-elasticity coupling dual-station welding fixture to solve the problems mentioned in the background art. Traditional welding methods usually use simple support fixtures to fix the workpiece, and then welders or welding robots perform continuous circumferential welding. Continuous and uninterrupted welding will cause large welding stress inside the workpiece. This stress will cause the workpiece to deform, which will seriously affect the dimensional accuracy and performance of the product. Single-station operation makes it impossible for the loading and unloading time to overlap with the welding time, thereby reducing production efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel high-elasticity coupling dual-station welding fixture, comprising a fixture table, on both sides of the bottom of the fixture table being bolted with drive motors, a rotating plate being bolted to the output end of the drive motors, an annular frame being bolted to the top of the rotating plate, a mounting base being bolted to the top of the rotating plate, cylinders being bolted to the front, back and sides of the mounting base, a push block being provided at the telescopic end of the cylinders, a gear ring being placed inside the annular frame, an annular plate being fitted on the surface of the gear ring, and several quick clamps being arranged in a circular array on the top of the fixture table.

[0006] Preferably, the bottom of the quick clamp is bolted with a support column, and the bottom of the support column is fixedly connected to the rotating plate.

[0007] Preferably, the surface of the ring frame is provided with a groove, and the vertical joint of the toothed ring is in the same direction as the groove.

[0008] Preferably, a protective plate is provided on the top of the push block, and a mounting bolt is sleeved inside the protective plate, with the bottom of the mounting bolt threadedly connected to the push block.

[0009] Preferably, a fixing bolt is fitted inside the push block, and one end of the fixing bolt is threadedly connected to the telescopic end of the cylinder.

[0010] Preferably, a partition is provided between the two rotating plates, and the bottom of the partition is fixedly connected to the tooling table.

[0011] This utility model has the following beneficial effects: This device features a dual-station structure. Users pre-fit the annular plate and gear ring, aligning the groove at the gear ring joint with the groove inside the annular frame. A quick-clamping device then reliably and quickly positions the annular plate. The operation is simple and the positioning is precise. A cylinder-driven pusher block abuts and limits the gear ring, effectively enhancing stability during welding and preventing workpiece displacement. A welding robot performs welding at the connection between the annular plate and gear ring. A drive motor rotates the plate, allowing for flexible switching between different welding positions. Step-by-step, intermittent welding effectively disperses and reduces welding stress generated by continuous concentrated welding, significantly improving the welding quality and structural reliability of the workpiece while reducing the risk of deformation. The overall structure is rationally designed, combining practicality and high efficiency. Attached Figure Description

The operation is simple and the positioning is precise. The cylinder 6 drives the push block 7 to abut and limit the gear ring 8, effectively enhancing the stability of the welding process and preventing workpiece displacement. A welding robot is used to weld the connection between the annular plate 9 and the gear ring 8. Combined with the drive motor 3 driving the rotating plate 2 to rotate and adjust, flexible switching between different welding positions is achieved.

[0021] refer to Figure 1A partition 16 is provided between the two rotating plates 2. The bottom of the partition 16 is fixedly connected to the tooling table 1. By setting the partition 16, the welding light can be shielded from the other station during the welding process.

[0022] Brief description of the usage process: The user can pre-fit the annular plate 9 and the toothed ring 8, align the joint of the toothed ring 8 with the groove 12 and place it inside the annular frame 4, then use the quick clamp 10 to limit the position of the annular plate 9, then start the cylinder 6 to drive the push block 7 to abut and limit the position of the toothed ring 8, and use the welding robot to weld the connection between the annular plate 9 and the toothed ring 8. The drive motor 3 drives the rotating plate 2 to rotate and adjust the diagonal welding position, which can avoid the welding stress of continuous welding.
