Gear grinding clamping device of planetary gear of wind power generation device

Abstract

Provided is a gear grinding clamping device of a planetary gear of a wind power generation device. The gear grinding clamping device comprises a clamp holder used for supporting a workpiece and a shaft locating pressing block, the clamp holder is shaped like a ladder-shaped cylinder, the bottom of the ladder-shaped cylinder is provided with an installing locating bottom platform with the diameter larger than that of the middle section cylinder, and multiple radial open slots used for installing and fixing are formed in the circumference of the installing locating bottom platform; a workpiece locating platform with the diameter larger than that of the middle section cylinder is arranged on the upper portion of the ladder-shaped cylinder, the upper end of the workpiece locating platform is provided with a circular centering locating step, a convex table portion of the circular centering locating step and the installing locating bottom platform are concentric circles, the diameter of the convex table portion is 0.05-0.1 mm smaller than that of a shaft hole of a machined gear, and the horizontal plane of the circular centering locating step is parallel to the bottom face of the installing locating bottom platform; a threaded hole is formed in the circle center of the circular centering locating step, the lower end of a screw is fixedly connected with the threaded hole, the shaft locating pressing block is arranged on the screw in a sleeving mode through a formed via hole, and the shaft locating pressing block is pressed through a nut.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a tooth grinding and clamping device for a planetary gear of wind power generating equipment. Background technique [0002] For gear processing in the machinery manufacturing industry, for the grinding process of different gears, corresponding gear grinding tools are required to clamp and position the processed gears to ensure the smooth progress of the gear grinding process. In view of the large volume of planetary gears of wind power generation equipment, the diameter is usually greater than 400mm, the existing tooling for grinding teeth of such planetary gears does not have a pre-positioning function structure for the inner hole of the workpiece, which increases the workload of workpiece clamping and alignment, and , Every time the workpiece is clamped, the screw of the tooling connection table needs to be adjusted to level and align the workpiece. In this way, for mass production, each wo...

In view of the large volume of planetary gears of wind power generation equipment, the diameter is usually greater than 400mm, the existing tooling for grinding teeth of such planetary gears does not have a pre-positioning function structure for the inner hole of the workpiece, which increases the workload of workpiece clamping and alignment, and , every time the workpiece is clamped, the screw of the tooling and the worktable needs to be adjusted to level and align the workpiece. In this way, for mass production, each workpiece needs to be leveled and aligned in this way, which is low in efficiency, difficult and high in strength
