[0002] The automotive half-axle drilling device is a key mechanical equipment used to accurately drill holes on the automotive half-axle. These holes are mainly used to install fixed components or as a component of the lubrication system. The device is usually equipped with a high-precision CNC system to achieve automation and multi-axis drilling to improve production efficiency and processing accuracy. With the advancement of technology, modern drilling devices not only emphasize durability and easy maintenance, but also integrate intelligent control systems and environmental protection technologies to optimize the processing process and reduce environmental impact. These technological innovations have a significant industrial and market impact on the automotive manufacturing industry in terms of improving manufacturing efficiency, reducing costs and enhancing product reliability.

[0003] After searching, the existing patent (Announcement No.: CN217800419U) discloses a vehicle half-axle drilling device, including a bottom plate, the upper surface of the bottom plate is respectively fixedly connected with a support column and a lower arc-shaped clamping plate, the top of the support column is fixedly connected with a top plate, the surface of the top plate is respectively provided with a clamping mechanism and a height adjustment mechanism, the clamping mechanism includes a hydraulic rod fixedly arranged on the lower surface of the top plate, the telescopic end of the hydraulic rod is fixedly connected with an upper arc-shaped clamping plate, and the upper arc-shaped clamping plate is adapted to the lower arc-shaped clamping plate. The vehicle half-axle drilling device, after the half-axle is clamped and positioned, the electric telescopic rod is extended, and the drill drives the drill bit to rotate, so that the operation of drilling holes at both ends of the half-axle can be realized at the same time, and the efficiency of drilling processing is improved. When processing half-axles of different diameters, the axis height of the half-axle changes, and the vertical screw is driven to rotate by the rotation of the lifting motor. Under the limiting action of the limiting slider, the moving screw block is stably lifted and lowered, and the height of the drilling rig and the drill bit is adjusted, thereby expanding the application range of the overall device.

[0004] However, in the actual use of the above solution, after the half-shaft is fixed by the clamp, the half-shaft is not allowed to adjust its angle during the drilling process, which may lead to inaccurate drilling position. For applications that require extremely high precision, this fixing method may not be sufficient to meet the requirements.

[0005] To this end, the utility model provides a vehicle half-axle drilling device. Utility Model Content
