Description

Technical Field

[0001] The utility model relates to the field of large gear processing equipment, in particular to a large gear clamping turntable iron chip separation device. Background Art

[0002] The processing of large gears requires the use of a matching large vertical lathe. The annular gear blank is placed on the turntable fixture of the vertical lathe and clamped and fixed. The gear blank is then supported by the fixture to rotate so that the outer circle of the gear blank can be processed using a turning tool. Due to the large diameter of the fixture of such large gears, the metal chips generated by cutting will rotate with the turntable fixture and diffuse to the outside of the vertical lathe under the action of centrifugation, making it difficult to clean the chips and even get stuck in the rotating mechanism of the turntable, affecting the processing process. In addition, if the high-temperature metal chips are not collected, there is a risk of scalding or cutting the staff, which is not practical. Utility Model Content
