Description

Technical Field

[0001] The invention relates to the technical field of front axle shaft head press-fitting equipment, and in particular to a front axle shaft head and axle tube press-fitting equipment with angle adjustment. Background Art

[0002] The front axle is mostly a driven axle, also known as a steering axle, which is generally distributed at the front end of the vehicle, so it is called the front axle. It is connected to the steering system using a steering knuckle. It can transmit the steering force output by the steering gear to the wheels to achieve the steering of the vehicle. It not only supports the sprung mass at the front of the vehicle and bears the vertical load, but also bears various longitudinal forces, lateral forces and related moments. Therefore, how to ensure the effective press-fitting of the front axle and ensure that the front axle has sufficient strength and rigidity not only determines the quality of the front axle assembly, but also affects the safety of the vehicle's driving and steering. This has become a key point in ensuring the assembly quality of the front axle assembly.

[0003] The existing front axle shaft head press-fitting method is to support the front axle and then manually press-fit the two ends. The positioning accuracy is low, the stability is poor, and the press-fitting efficiency is low. In addition, since the shaft head and the bridge tube are interference fit, it is difficult to press-fit into place manually and it is easy to cause the left and right ends of the shaft head to be misaligned, resulting in press-fitting errors, poor compatibility in subsequent use, and low durability. In order to meet large-scale and large-volume production, it is urgent to develop efficient and high-quality front axle shaft head press-fitting equipment. This requires that the press-fitting process of the front axle shaft head cannot be the same as the traditional press-fitting process. It must be upgraded to improve the positioning accuracy and clamping stability of the bridge tube and the front axle shaft head, and be able to distinguish between the left and right ends, effectively prevent errors, and achieve synchronous press-fitting of the two ends through the pressure applied by the cylinder and the oil cylinder; therefore, a new type of front axle shaft head and bridge tube with angle adjustment press-fitting equipment is proposed. Summary of the invention
