Clamping device for cover of wind power gear box

Abstract

The invention discloses a clamping device for a cover of a wind power gear box, and belongs to the technical field of machining. The clamping device for the cover of the wind power gear box comprisesa first base, a second base, a first clamping unit, a second clamping unit, a first pressing unit, a second pressing unit and an adjustment unit, wherein the first base and the second base are slidably connected with a worktable separately and can support the cover; the first clamping unit and the second clamping unit are arranged on the first base and the second base respectively and used for positioning of a first bearing hole and a second bearing hole respectively; the first pressing unit and the second pressing unit are slidably connected with the worktable and used for pressing the upperend faces of the first bearing hole and the second bearing hole respectively; and the adjustment unit is arranged on the worktable and can abut upon the edge of the bottom surface of the cover to support and adjust the height of the cover. The clamping device for the cover of the wind power gear box is high in universality, improves the production efficiency and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a clamping device for a case cover of a wind power gearbox. Background technique [0002] Wind power gearbox case cover milling is the first finishing process after rough machining. For traditional vertical machining centers, the connection between the center of the two bearing holes and the machine tool can only be corrected according to the difference in diameter between the two bearing holes. The X axis is parallel, and a bearing hole is used as the programming zero point to mill the box cover surface and process the threaded hole and positioning pin hole on the box surface. However, this correction method needs to adjust the position of the bearing hole on the Y-axis of the machine tool multiple times to meet the parallel line between the centers of the two bearing holes and the X-axis of the machine tool, resulting in more auxiliary time for assembly and calibr...

Problems solved by technology

However, this correction method needs to adjust the position of the bearing hole on the Y-axis of the machine tool multiple times to meet the parallel line between the centers of the two bearing holes and the X-axis of the machine tool, resulting in more auxiliary time for assembly and calibration than the normal processing time of the part. Reduced processing production efficiency; in addition, in the prior art, the spacing of the clamping device is fixed, which can only be used for the milling process of a wind power gearbox cover, and the versatility is poor. When producing case covers with different sizes of center distances , it needs to be equipped with multiple clamping devices, frequent replacement is time-consuming and laborious, and the production cost is high
