Problems solved by technology
The traditional blade drilling method is to use the drill rod of the radial drilling machine to drill through the tooling with the same positioning hole as the center hole of the workpiece to drill holes. In addition to equipment errors and operation errors, this method also has machining errors of the tooling , assembly errors, etc., resulting in large cumulative errors, so it is difficult to meet the requirements

The invention belongs to the technical field of auxiliary equipment for machining, and particularly relates to a clamping tool for drilling a center hole in a curved surface forging. According to themain technical scheme, the clamping tool comprises a rack, and a clamping template arranged in the rack, wherein the clamping template comprises a lower template and an upper template which are used for locating the curved surface forging; the lower template is arranged in a base of the rack, and the curved surface forging is clamped through the upper template and the lower template by pressing alever; and one side or the two opposite sides of the upper template are provided with reference holes matched with tool setting bars of a computer numerical control milling machine for detection. Theclamping tool for drilling the center hole in the curved surface forging has the characteristics that the clamping tool is not limited by the appearance of the curved surface forging, and the positionaccuracy of the center hole is high; and the tolerance of the distance between the centers of the center holes is small.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing auxiliary equipment, and specifically relates to a clamping tool for drilling a center hole of a curved surface forging. Background technique [0002] As the forging process matures, forging workpieces become more and more complex. The precise core components of steam turbines, gas turbines, aero engines, blowers and other equipment are all forged. The requirements are high, and it is generally produced by a five-axis CNC machining center. Before processing, it is necessary to drill center holes on both ends of the blank, and the accuracy of the center hole distance is high, and the requirement is ±0.03mm. The traditional blade drilling method is to use the drill rod of the radial drilling machine to drill through the tooling with the same positioning hole as the center hole of the workpiece to drill holes. In addition to equipment errors and operation errors, this method also has ma...
