Description
Technical Field
The utility model belongs to the technical field of gear machining makes, concretely relates to thin wall gear internal grinding device.
Background
Thin-wall gears are widely used in various machines, but due to the structural particularity, the machining has been difficult. Particularly, after the low-carbon steel material is carburized and quenched, the deformation is large, and the internal grinding processing difficulty is large. It is difficult to ensure the precision of the finished product. The measures adopted in the prior production of the gear are to change the material from low-carbon steel to medium-carbon steel, change the process scheme from tumbling to rolling shaving and change carburizing and quenching into soft nitriding treatment with smaller deformation. However, the precision of the gear shaving gear is not as high as that of a gear grinding gear, generally about 6-7 grades, and the gear shaving gear can not meet the requirements of products with high precision requirements. The other scheme is that the material is unchanged, and the method for correcting pitch circle and end face is adopted for processing during internal grinding after carburizing and quenching, so that the mode has large deformation and low product percent of pass.
Disclosure of Invention
For solving the problem that exists among the prior art, the utility model provides a thin wall gear internal grinding device, including positioning disk and holder, the positioning disk with the holder is connected, set up the bolt hole on the positioning disk, the downthehole mounting nut of bolt, the one end connecting stud of nut.
Preferably, a hexagonal flange nut is mounted on the stud.
In any of the above solutions, preferably, the center of the positioning plate is a groove.
In any of the above aspects, preferably, the retainer is disposed in the groove.
