Embodiment 1

[0057] As an embodiment of this application, in combination with Figure 2-7 The numerical control processing method described in the present application is further explained, and the content mentioned above will not be repeated here, and further explanations will be given for specific examples.

[0058] Such as Figure 2-3 As shown, in the processing process, the holes to be processed need to be grouped first, which can better simplify the processing. figure 2 , 3 It shows the grouping of processing holes on the outer wall of the ball and the inner wall of the ball respectively. It can be seen that the method described in this application not only supports the support on the outer wall of the ball but also can be used on the inner wall of the ball.

[0059] Specifically, firstly, the head is clamped with the J-groove side upwards, and placed according to the predetermined orientation. G54X0Y0 is set at the center of rotation of the head. At this time, each hole where the J...

Abstract

The invention provides a machining method for J-shaped grooves of series pipe base holes in a thin-wall irregular spherical end socket. The machining method comprises the following steps that series holes are grouped; establishing a workpiece digital model according to the grouped series holes; a CAM program is developed according to a preset process scheme, and a machining tool is determined; checking the developed CAM program according to VERICUT numerical control machine tool simulation software; and detecting the dimensional accuracy of the workpiece by detecting the feature points through a machine tool. According to the method, the solution for machining the J-shaped groove in the irregular spherical surface is solved, the problem that the machining procedure of the J-shaped groove of a series of holes is tedious is solved, the final machining effect can meet all dimensional precision requirements of drawings, the surface quality of products is greatly improved, and meanwhile the machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of parts processing, in particular to a processing method for a series of J-shaped bevels of socket holes on a thin-walled irregular spherical head. Background technique [0002] The J-groove welded between the socket hole and the spherical head is a complex space surface, and the number of series holes is as many as dozens or nearly a hundred. It is worth mentioning that the spherical surface is an irregular surface. At present, there is only one traceable processing technology. The difference between its background and this plan is that the number of holes in the series is small, and the spherical surface is a regular spherical surface. This processing method cannot guarantee the dimensional accuracy requirements, and the surface roughness cannot be satisfied. The processing method is backward, the processing efficiency is extremely low, and the cost is high. Contents of the invention [0003] According...
