Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and in particular to a surface treatment device and method for processing bevel gears. Background Art

[0002] The surface treatment of bevel gears is an important process aimed at improving their performance, extending their service life and increasing their reliability. The surface treatment of bevel gears mainly includes grinding, sandblasting, heat treatment and coating treatment. Among them, whether it is heat treatment, coating treatment or chemical treatment, the oxide layer, rust and dust on the surface of the bevel gears need to be removed before treatment.

[0003] Sandblasting is the process of using high-speed airflow to spray abrasives onto the surface of bevel gears to remove surface dirt, oxides and old coatings, and increase surface roughness. Sandblasting can improve the surface quality of bevel gears, increase surface adhesion, and provide a good foundation for subsequent coating or bonding processes. At present, sandblasting usually requires the use of a sandblasting device, which consists of a fixture, a nozzle, and a robotic arm. During the process, the bevel gear is clamped and positioned by the fixture, and the robotic arm drives the nozzle to align the bevel gear surface for sandblasting. At present, the following deficiencies exist in the sandblasting process:

[0004] First, due to the shape limitation of the bevel gear, the inner ring position is not convenient for the sandblasting head to be aligned during the sandblasting process. In the actual processing process, the inner and outer ring processing positions are prone to poor processing effects;

[0005] Second, during the processing, the robot arm action is usually used to achieve sandblasting of various positions of the bevel gear. However, there are many types of bevel gears with different radii, so the robot arm action that needs to be adjusted is complex, resulting in complex programming. In the actual operation process, the complex robot arm action may also cause interference and collision between the robot arm and the gear due to misoperation, damaging the equipment and workpiece, and it is also easy to cause uneven sandblasting on the workpiece surface;

[0006] Third, the sandblasting equipment is usually designed with a single station. During the actual processing, each time the bevel gear is replaced for processing, it is necessary to stop the machine and replace the workpiece to be processed, which is cumbersome and reduces efficiency. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a surface treatment device and method for bevel gear processing. The design of the rotating bearing component allows the bevel gear workpiece to rotate by itself, so that various parts of the surface of the bevel gear workpiece are evenly treated during the sandblasting process. After the bevel gear workpiece is positioned, the inclination angle switching component is designed to facilitate the inner ring and outer ring to be aligned under the sandblasting head during the processing of the bevel gear workpiece. The robotic arm will not interfere with the bevel gear workpiece, thereby protecting the equipment and the workpiece and ensuring that the processing position of the inner ring and the outer ring is well treated. The station switching unit design facilitates multi-station switching and improves the surface treatment efficiency of the bevel gear workpiece.

During the clamping process, the clamping member 9 is driven to move by adjusting the position of the adjusting block 802, and finally the two groups of clamping members 9 are used to clamp and position the bevel gear workpiece 10.

[0076] Furthermore, the internal rotation connection of the clamping and positioning seat 8 is provided with a double-threaded screw 801, and the double-threaded screw 801 is threadedly connected to the adjustment block 802.

With the design of the inclination angle switching assembly, it is convenient to align the inner ring and the outer ring under the sandblasting head 202 during the processing of the bevel gear workpiece 10.

The mechanical arm 201 will not interfere with the bevel gear workpiece 10, so as to protect the equipment and the workpiece, and also ensure that the processing position of the inner ring and the outer ring is well processed.
