Embodiment Construction
[0024] see Figure 3-5 , a method for processing and aligning a split part provided by an embodiment of the present invention, the split part is composed of two single pieces 5, and the single piece 5 includes a semi-circular piece 5-1 and two connecting plates 5-2, The two connecting plates 5-2 are respectively fixedly arranged on both sides of the diameter direction of the semi-annular part 5-1, and the semi-annular parts of the two single parts 5 are opposite, and the two connecting plates 5-2 of the two single parts 5 are opposite to each other. Assembled to form a split part, the middle parting surface is formed between the two single parts 5, the side of the two connecting plates 5-2 is the first processing surface, the first processing surface is perpendicular to the middle parting surface 6, and the end face of the semi-circular part It is the second processing surface, and the outer arc surface of the half-ring is the third processing surface. The processing method of...

The invention discloses a processing alignment method for split parts, which belongs to the technical field of processing alignment technology. The processing method of the split part includes the following steps: taking the mid-section plane as a reference, machining two third datum planes on the third processing plane, the two third datum planes and the mid-plane The split planes are parallel, and the distance between the two third reference planes and the middle split plane is equal; the two single pieces are assembled to form split parts, and the split parts are placed on the first processing equipment On the workbench; through the second datum plane, it is determined that the split plane of the split part is perpendicular to the workbench of the first processing equipment. The method for processing and aligning the split parts of the present invention can realize the alignment of the mid-section surface and the axis of the inner hole of the split parts after assembly, and avoid the large / small half phenomenon of the split parts.
Description
technical field [0001] The invention relates to the technical field of processing alignment technology, in particular to a processing alignment method for split parts. Background technique [0002] In mechanical equipment, some shell parts with split structure are often encountered. In order to ensure the good operation of the equipment, it is required that the split surface of the split part after finishing is a section passing through the center of rotation of the part. That is to say, during the processing of parts, there should be no phenomenon of large and small parts. [0003] However, the processing and alignment after the assembly of conventional split parts is based on the joint line 1 of the upper and lower half of the part on the outer surface (such as figure 1 shown), as well as inner hole and outer circle alignment. Due to the large alignment error according to the joint line of the split surface on the outer surface, the actual split surface of the finished ...
