Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical processing technical field, concretely is a gear manufacturing fixture equipment. BACKGROUND

[0002] Gear manufacturing fixture equipment is a special device for positioning and clamping gear blank in gear machining process to ensure machining accuracy and improve production efficiency, which plays a vital role in various links of gear manufacturing, such as cutting, grinding, drilling and other machining processes.

[0003] Top device function: used for determining the axial position of gear blank, ensuring the axial accuracy of gear during machining, generally having fixed top and movable top, the fixed top is installed at one end of the fixture, and the movable top can be relatively moved through a certain driving device (such as hydraulic or pneumatic device) to better adapt to gear blanks of different sizes and exert axial positioning force on them;

[0004] Working principle: when the gear blank is installed on the fixture, the fixed top first presses against the center hole of one end of the gear, and then the movable top moves to the other end of the gear and is pressed tightly, so that the gear is accurately positioned in the axial direction, for example, when grinding the outer circle of the gear, the top device can ensure that the rotation axis of the gear is parallel to the axis of the grinding wheel, improving the grinding accuracy of the outer circle.
