Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to a wide-seam continuous welding machine for a drive shaft. Background Technology

[0002] The driveshaft is the power-transmitting shaft in a universal joint drive system. It is a high-speed, low-support rotating body. Current manufacturing processes involve first assembling the various driveshaft components on a press-fitting machine, and then pressing, straightening, and welding them on a specialized welding machine. This driveshaft welding process requires a lot of equipment. First, the components are pressed together using a press-fitting machine. After pressing, straightening is performed, either manually by hammering or using new machinery. Finally, welding begins. The bicycle driveshaft is a crucial component connecting the power unit and the wheel; therefore, strict requirements are placed on the wide-seam welding of the driveshaft. This allows for continuous welding of the wide seams of the bicycle driveshaft.

[0003] In existing related technologies, the drive shaft is first transported to the welding machine. During the welding process, due to the long length of the drive shaft, it is prone to deformation and cannot be effectively supported. Therefore, there is an urgent need to design a wide-seam continuous welding machine for the drive shaft to solve these problems. Utility Model Content

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A wide-seam continuous welding machine for a drive shaft includes a base, a clamping support mechanism disposed above the base, and a welding execution mechanism disposed above the clamping support mechanism.

[0007] The clamping and support mechanism includes a first lead screw that is laterally rotatably mounted above the base. A first movable stage is movably mounted on the outer surface of the first lead screw. A first motor is fixedly mounted at one end of the first lead screw. A vertical plate is fixedly mounted vertically and parallel above the first movable stage. A corner motor is fixedly mounted on the vertical plate.

[0012] Preferably, the longitudinal movement assembly includes a longitudinal movement platform mounted on an L-shaped frame, and a second electric telescopic rod is fixedly mounted on the longitudinal movement platform.

[0013] The beneficial effects are:

[0014] This utility model discloses a wide-seam continuous welding machine for drive shafts. Through a clamping and support mechanism, a first motor drives a first lead screw to rotate. Simultaneously, a first movable table, movably mounted on the outer surface of the lead screw, moves relative to or towards the first lead screw, installing the drive shaft to be welded within a clamping plate. A first electric telescopic rod pushes the clamping plate to clamp and fix the drive shaft. Simultaneously, a first electric cylinder pushes a support plate, a second electric cylinder, and an arc-shaped carrier plate to move laterally. When welding is required, the second electric cylinder pushes the arc-shaped carrier plate upwards, providing support for the clamped drive shaft at a certain distance. This ensures effective support during welding, increases the fixation of the drive shaft, improves welding efficiency, and is convenient and practical. Attached Figure Description

[0026] Working principle: In use, the first motor 202 is started to drive the first lead screw 201 to rotate.

The second motor 302 is started to drive the second lead screw 301 to rotate, driving the second movable table 303, the L-shaped frame 304, and the welding... The welding machine 308 moves laterally left and right. When welding is required, the second electric cylinder 211 is activated to push the arc-shaped carrier plate 212 upward. The arc-shaped carrier plate 212 supports the clamped and fixed transmission shaft at a certain distance, allowing the welding machine 308 and welding wire 309 to move laterally above the transmission shaft to be welded. At the same time, the second electric telescopic rod 305 is activated to push the longitudinal moving table 306, welding machine 308, and welding wire 309 to make longitudinal fine adjustments, so that the welding machine 308 and welding wire 309 can easily perform wide-seam continuous welding on the transmission shaft.

After a certain period of use, the movable grate plate 311 can be moved and cleaned to complete the wide-seam continuous welding of the transmission shaft.
