Description

Technical Field

[0001] The invention relates to the technical field of automobile metal part drilling, in particular to an automobile steering knuckle drilling pre-processing machine tool. Background Art

[0002] The automobile steering knuckle is a key component in the automobile suspension system. It connects the wheel to the suspension and allows the wheel to rotate when turning. The steering knuckle usually needs to have high strength and durability to withstand the weight of the vehicle and road impact, so its manufacturing process and quality control are very important. The steering knuckle is usually manufactured by casting. Common processes include sand casting, precision casting and pressure casting. The choice of casting process depends on factors such as materials, design complexity and production cost. During the casting process, the design of the pouring head is a key factor in ensuring the quality of the casting. The function of the pouring head is to guide the molten metal into the cavity, while venting and filling the shrinkage to prevent defects such as pores and shrinkage holes in the casting.

[0003] Removing the pouring spout and drilling holes are important steps in steering knuckle processing. The removal of pouring spouts is usually done by sawing machines or drilling machines, which are inefficient and require manual operation, easily resulting in high labor intensity and difficulty in ensuring the flatness of the cut surface, which may require subsequent processing. The drilling operation has the problem that existing drilling equipment is difficult to ensure the position accuracy and dimensional accuracy of the holes, especially for castings with complex shapes. The processing speed of a single device is slow and it is difficult to meet the needs of mass production. Summary of the invention
