Description

Technical Field

[0001] The present application relates to the technical field of wind power equipment production, and in particular to a processing and clamping device for wind power planetary gears. Background Art

[0002] Wind power planetary gears are high-precision gears used in wind power generation equipment. The existing technology generally produces wind power planetary gears in the order of first machining the inner hole on the gear blank and then machining the outer teeth. Due to the high precision requirements of wind power planetary gears, it is necessary to use a gear grinding process to process the tooth surface of the gear blank.

[0003] During processing, workers will first fit the inner hole of the gear blank onto the claws of the chuck, and then use the claw driving mechanism to drive each claw to abut against the inner hole wall of the gear blank so as to fix the gear blank on the chuck. Then start the grinding equipment and make the grinding wheel on the grinding equipment abut against the outer ring of the gear blank. Finally, drive the chuck to drive the gear blank to rotate and process a circle of external teeth on the gear blank.

[0004] However, since the grinding wheel will exert a certain stress on the gear blank while grinding it, and when the chuck is clamped into the inner hole of the gear blank, there will be a section without support between every two adjacent claws. When the grinding wheel grinds to the outer ring corresponding to these sections, these sections are prone to shrink a certain amount toward the axis of the gear blank, causing the gear blank to deform and become scrap, resulting in a high scrap rate in the wind power planetary gear grinding process. Summary of the invention

[0049] Through the above-mentioned arrangement, when the abutment wheel 2 is in a contracted state, a guide bar 3233 will be inserted into the tooth groove of each connecting member 324, and when the abutment wheel 2 is changed from a contracted state to a relaxed state, the connecting member 324 will slide along the guide bar 3233 toward the gear segment 3232 and finally mesh with the gear segment 3232, so that the abutment member 323 can be driven to rotate by the rotating device 4 to drive a pair of connecting members 324 to rotate, and then the movable shaft 312, the abutment wheel 2 and the gear blank 5 can be driven to rotate through the connecting member 324; and when the abutment wheel 2 is changed from a relaxed state to a contracted state, a pair of connecting members 324 will be separated from the gear segment 3232 and will be meshed with a corresponding guide bar 3233 again, so that the connecting member 324 can be guided by the setting of the guide bar 3233 to prevent the connecting member 324 and the gear segment 3232 from being offset and unable to mesh.

[0050] It should be noted that the worker can electrically connect the rotating device 4 to the controller (not shown in the figure) so that after the grinding of the gear blank 5 is completed, the worker can control the rotating device 4 through the controller to rotate the abutment 323 to a position that can ensure that each guide bar 3233 is aligned with a corresponding connecting member 324, so as to ensure that when the abutment wheel 2 changes from a dilated state to a contracted state, each guide bar 3233 can be smoothly inserted into the groove of a corresponding connecting member 324.

After the abutment wheel 2 abuts against the inner hole wall of the gear blank 5, the buffer can absorb the stress transmitted to the gear blank 5 by the grinding wheel, so that the gear blank 5 is less likely to be affected by the stress and the inner hole deformation occurs during grinding, thereby making the gear grinding processing of the wind power planetary gear have a higher yield rate.
