Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a surface processing device for automotive wheel hub bearing flanges. Background Technology

[0002] As a key component of automotive transmission systems, the surface finish of wheel hub bearing flanges directly affects the bearing's load-bearing capacity, sealing performance, and service life. Currently, the processing of wheel hub bearing flanges still suffers from the following technical deficiencies:

[0003] 1. Decentralization of multiple processes leads to low efficiency: Traditional processes require multiple independent machines to complete milling, drilling, grinding and other processes in sequence. The workpiece needs to be clamped and positioned repeatedly, resulting in a long processing cycle and easy to cause dimensional errors due to datum offset, making it difficult to ensure processing consistency.

[0004] 2. Limited processing functions: Existing equipment is usually only compatible with a single type of tool (such as a dedicated milling machine or grinding machine), and cannot integrate multiple processing functions in the same workstation, making it difficult to meet complex surface treatment needs;

[0005] 3. Tool switching relies on manual intervention: In multi-process processing, operators need to frequently change tools or adjust fixtures manually, resulting in low automation, which not only increases labor intensity but also poses safety hazards;

[0006] 4. Insufficient dynamic coordination: Conventional equipment mostly adopts a fixed processing mode, where the workpiece is stationary and the tool feeds in one direction. It is difficult to achieve dynamic coordination between workpiece rotation and radial / axial movement of the tool, resulting in poor surface treatment uniformity. In particular, it is difficult to control the processing accuracy of curved or irregular flange edges.

[0007] The aforementioned problems severely restrict the mass production efficiency and processing quality of wheel hub bearing flanges. Therefore, there is an urgent need to develop an integrated, high-precision machining device capable of multi-process continuous operation, automatic tool changing, and dynamic collaborative machining, thereby breaking through the industry's technical bottlenecks. Utility Model Content

[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a machining device with multi-process integration, automated tool changing and dynamic collaborative control functions.

In use, the first motor drives the chuck and the wheel hub bearing fixed to the chuck to rotate. The drive device is provided on the processing table, and a movable plate is connected to the drive device. The drive device can drive the movable plate to move along the processing table, allowing the processing equipment to approach the wheel hub bearing on the chuck, thereby processing the surface of the wheel hub bearing flange. A traversing device is fixedly connected to one side of the movable plate, and the processing equipment is connected to the traversing device. The traversing device can drive the processing equipment to move laterally, facilitating precise processing of the wheel hub bearing surface.

[0010] In the above technical solution, the driving device includes a driving block, a sliding block, a first threaded rod, and a second motor.

The lower end of the movable plate is fixedly connected to the driving block and the sliding block respectively.

[0011] In the above technical solution, the traversing device includes a mounting plate, a third motor, a second threaded rod, a sliding guide rail, and a sliding guide block. The mounting plate is fixedly connected to one side of the movable plate, and two sets of symmetrical sliding guide rails are fixedly connected to the mounting plate. A second threaded rod is rotatably connected to one side of the mounting plate between the sliding guide rails, and a sliding guide block is threaded onto the second threaded rod. One side of the sliding guide block is slidably connected to the sliding guide rail, and the other side of the sliding guide block is fixedly connected to a processing device.

[0012] In the above technical solution, the processing equipment includes a mounting base, a fourth motor, a keyway block, and a milling cutter converter. The mounting base is fixedly connected to one side of the sliding guide block. The fourth motor is fixedly connected to the mounting base. The end of the rotating shaft of the fourth motor is fixedly connected to the keyway block. A spline groove is opened on one side of the keyway block. The spline groove is connected to the milling cutter converter. The milling cutter converter is fixedly connected to one side of the fourth motor.

[0013] In the above technical solution, the milling cutter converter includes a clamp, a clamp block, an electric push rod, a U-shaped bracket, a ball bearing, a conversion disc, a machining part, a spline head, a first gear, a second gear, and a fifth motor. The clamp and the clamp block are fixed by bolts, and a mounting hole is provided between the clamp and the clamp block. The middle part of the fourth motor is fixedly connected in the mounting hole. An electric push rod is rotatably connected to the clamp block. Slot holes are opened on the clamp blocks located on both sides of the electric push rod. The U-shaped bracket is slidably connected in the slot holes, and a ball bearing is fixedly connected in the middle of the U-shaped bracket.

[0014] The beneficial effects of this utility model are:

[0015] 1. Process integration improves efficiency: By integrating multi-functional modules such as milling, drilling, and grinding, the entire process of wheel hub bearing flange processing can be completed at the same workstation, reducing the number of workpieces that need to be clamped repeatedly, significantly shortening the processing cycle and eliminating reference errors, thereby improving processing consistency and production efficiency.

[0016] 2. Multifunctional integration and high equipment utilization: The modularly designed milling cutter converter supports rapid switching between multiple tools such as face milling cutters, cylindrical milling cutters, and grinding heads, breaking through the limitations of traditional equipment with single functions, meeting the needs of complex surface treatment, and improving the overall utilization rate and space efficiency of the equipment.

[0017] 3. Automated tool changing and safety optimization: Based on the linkage mechanism of gear transmission and electric push rod, the automatic alignment and spline engagement of the workpiece are realized. No manual intervention is required for tool changing, which reduces operational risks while ensuring tool changing accuracy and meets the needs of continuous machining.

[0018] 4. Dynamic collaborative machining improves accuracy: By combining the chuck-driven workpiece rotation with the bidirectional feed control of the drive device and the traverse device, dynamic matching between the radial / axial movement of the tool and the rotation of the workpiece is achieved, ensuring uniform cutting and grinding of complex curved surfaces (such as flange edges), and improving surface machining quality and dimensional accuracy.
