Embodiment 1

[0031] This embodiment is a machining fixture for two perpendicularly intersecting axes. The vertically intersecting axes include a first axis with a vertical axis and a second axis with a horizontal axis, and the first and second axes are perpendicular to each other and intersect. The clamp includes a compression block 1 , an adjustment screw 2 , a stop nut 3 , a fixed support 4 , a compression screw 5 and a washer 6 .

[0032] Fixed support 4 is the tube shape that one end that 45# steel is made has end cap. The workpiece 7 is located in this fixed support 4 . The inner hole of the fixed support 4 is a stepped hole, and the step surface at the upper end of the inner hole of the fixed support 4 is the positioning notch of the workpiece, and the inner diameter of the positioning notch is consistent with the diameter of the workpiece positioning surface. The diameter of the middle section of the inner hole of the fixed support 4 is 30 mm larger than the sum of the outer diame...

Abstract

The invention discloses a numerical control processing fixture for two perpendicularly-crossed shafts. A workpiece is positioned inside a fixed support; the excircle surface at one side of the fixed support is provided with a second shaft installation hole; and the centre line of the second shaft installation hole and the center line of the fixed support are perpendicular to each other. A compression screw is arranged on the end surface of the opening end of the fixed support; and the bottom of the fixed support is provided with an adjusting screw by which a compression block is in close fit with the excircle surface of a first shaft of the workpiece. A step surface at the upper end of an inner hole of the fixed support is a positioning flange of the workpiece. By use of the numerical control processing fixture, the clamping force of a machine tool claw does not directly act on the workpiece, so the deformation of the workpiece caused by clamping is effectively reduced, and meanwhile deformation resulting from torque transferring through the workpiece is eliminated by a main shaft clamping fixture. The other end of the workpiece is provided with auxiliary supporting, the influences of cutting vibration on the processing precision of the workpiece are reduced and the processing quality of products is improved.

Description

technical field [0001] The invention relates to the machining industry, in particular to a numerically controlled machining fixture for two perpendicularly intersecting axes. Background technique [0002] With the continuous development of my country's aviation and aerospace industry, there are more and more special-shaped parts with complex shapes, such as parts with two perpendicular intersecting axes. For the processing of such parts, people have long realized the superiority and importance of multi-axis CNC technology, such as CNC five-axis turning and milling machining centers. Therefore, a large number of foreign countries have already adopted such equipment in the field of aviation and aerospace to replace traditional processing equipment, while China is relatively backward in this area, and there are mainly the following problems: ① Multi-axis NC programming is abstract and difficult to operate. ②Clamping and positioning methods are not easy to determine; ③Difficult...
