Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding equipment for processing automotive drive shafts. Background Technology

[0002] An automotive driveshaft is a mechanical device that transmits power and torque between two planes of rotation. It is typically used to transfer engine power from the gearbox to the vehicle's drive wheels. Driveshafts are generally annular, stabilized by a balancing joint, and connected to the drive wheels and the vehicle's control components. During operation, the driveshaft is subjected not only to tensile, bending, and torsional stresses, but also to additional loads from the suspension system.

[0003] In automotive driveshaft manufacturing, welding is always a crucial step, and the application of welding processes is closely related to the driveshaft's dynamic balance characteristics, service life, and transmission strength. Currently, there are two main welding processes used in driveshaft manufacturing: CO2 gas shielded welding and friction welding. However, due to various factors, both of these welding processes experience problems to varying degrees during operation, such as uneven melting, metal spatter, porosity, and joint deformation, which negatively impact the driveshaft's transmission performance. In this context, a new welding technology has emerged and is gradually replacing traditional welding processes, gaining widespread acceptance among driveshaft manufacturers. This technology, laser welding, uses a high-energy-density laser beam. By controlling parameters such as peak power, energy, width, and repetition frequency of the laser beam, laser welding is performed on the surface of the driveshaft workpiece.

[0004] However, existing welding techniques generally require manual rotation. This method of rotation adjustment not only poses significant safety risks, but also makes it difficult to achieve uniform rotation, easily resulting in rotation speeds that are too fast or too slow, leading to suboptimal welding results. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a welding equipment for processing automotive drive shafts.

[0006] The purpose of this utility model is achieved as follows: a welding equipment for processing automotive drive shafts includes a base, auxiliary mechanisms are installed on both sides of the base, and a laser welding head is fixedly installed on the middle of one side of the base through a vertical plate and a horizontal plate; The auxiliary mechanism includes a rotating drum, one end of which is fixedly mounted with a clamping cylinder. The clamping cylinder has three mounting slots on its inner side and an adjustment slot on one side. A clamping plate is movably mounted inside the mounting slot via a positioning ring. One end of the clamping plate is mounted on an adjustment plate inside the adjustment slot via a connecting ring. A pushing plate is mounted on one side of the adjustment plate via several connecting rods. Two servo electric cylinders are provided on one side of the pushing plate.

[0007] Furthermore, a number of auxiliary springs are fixedly provided on one side of the push plate, and the other end of the auxiliary springs is fixedly connected to one side of the rotating drum.

[0008] Furthermore, a positioning frame is fixedly provided at the lower part of the servo electric cylinder, and the positioning frame is fixedly installed on both sides of the rotating drum.

[0009] Furthermore, a bearing ring is fixedly installed on one side of the rotating drum, and support seats are welded to both ends of the base. The rotating drum is movably connected to the support seats through the bearing ring.

[0010] Furthermore, two shaft seats are fixedly provided on one side of the base, and a transmission shaft is movably installed inside the two shaft seats. A first rotating wheel is connected to the middle key of the transmission shaft. A servo motor is fixedly installed on the base, and a second rotating wheel is connected to the output shaft of the servo motor. The first rotating wheel and the second rotating wheel are connected by a first transmission belt.

[0011] Furthermore, a third rotating wheel is fixedly provided at one end of the rotating drum, and a fourth rotating wheel is keyed to both ends of the transmission shaft. The third rotating wheel and the fourth rotating wheel are connected by a second transmission belt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, this utility model uses a single servo motor to drive the auxiliary mechanisms at both ends, enabling them to operate synchronously and maintain consistency. This facilitates the synchronous rotation of the auxiliary mechanisms at both ends when clamping and fixing the automobile axle, which is convenient for subsequent welding by the laser welding head. Furthermore, the auxiliary mechanism can rotate while clamping and fixing the automotive drive shaft, facilitating welding. Specifically, the push plate is adjusted by a servo electric cylinder, allowing the push to adjust the position of the adjusting plate inside the adjusting groove. The clamping plate is positioned and installed via a positioning ring, and the clamping plate is connected to the positioning ring via a connecting ring. When the servo electric cylinder pushes, it can control the push plate and positioning ring to move forward, allowing the clamping plate to move forward and thus the outer clamping plate to retract, clamping and fixing the bearing and maintaining stability. In addition, the auxiliary spring protects the rotating drum from damage caused by pushing and collision. Attached Figure Description
