The outer contour of the positioning reference of the planetary disk is arranged in an arc shape, and the clamping end of the clamping block is an arc-shaped surface consistent with the shape of the outer contour of the positioning reference set on the planetary disk.

The length of the guide groove is not less than 30mm.

The support includes a fixed plate and a connector, the fixed plate is T-shaped, and the cross arm of the T-shaped fixed plate is fixedly connected with the bottom plate; The vertical arm of the T-shaped fixed plate is provided with a slot for the connector, which is embedded in the outer periphery of the vertical arm of the T-shaped fixed plate, and the cross arm of the T-shaped conical connector and the vertical arm of the T-shaped fixed plate The fastening parts are fastened between them, and at the same time, the inner cavity of the T-shaped truncated conical connector is connected with the connecting pin hole provided along the axis on the clamping block through the connecting pin.

According to above technical scheme, with respect to prior art, the present invention has following advantage:

The planetary disk ball socket processing fixture of the present invention guides the clamping block by setting the guide block, so that the axis of the clamping block and the axis of the guide groove are the same as the connection line between the positioning reference of the planetary disk and the center of the planetary disk. straight line, which can effectively ensure that the concentricity between the outer circle of the ball socket and the inner hole is not higher than 0.15; in addition, the length of the guide groove in the present invention is not lower than 30mm, so as to limit the workpiece during the machining process. Offset, enhance the stability of the positioning pin, and better prevent radial loosening of the product during processing, that is, to further ensure that the concentricity between the outer circle and the inner hole of the product is not higher than 0.15.
