[0002] In the prior art, for figure 1 The blank shown is machined as figure 2 For the parts shown, the processing steps include A stage: rough turning + top finishing; B stage: rough turning + outer surface finishing; C stage: inner hole finishing. In B stage, because the part passes through the four-jaw chuck Fixed on the lathe, the high clamping force of the four-jaw chuck will cause deformation of the part after processing. In addition, because the conical surface of the part is processed, due to the thin wall thickness of the part, it is necessary to reduce the cutting amount of each cutting and reduce the Cutting feed, otherwise greater deformation will occur, so it is necessary to continuously adjust the state of the lathe during operation, and the processing efficiency is low

Embodiment Construction
[0023] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0024] Such as Figure 3-Figure 6 Shown, a kind of manufacturing method of inner taper sleeve, comprises the following steps:
[0025] S1: forging, forging and processing according to the processing drawings to form blanks;
[0026] S2: Rough machining, after checking the allowance of the parts, clamp the parts to correct the circle, and then chamfer the outer circle, inner hole, height and all places to the drawing size;
[0027] S3: UT flaw detection;
[0028] S4: The bottom of the part is drilled according to the requirements of the drawing, the depth of the drilling M16 is 50mm, the depth of the tooth is 35mm, and the chamfer of the hole is 45°;

The invention discloses a method for manufacturing an inner taper sleeve, which comprises the following steps: S1: forging, forging and processing to form a blank according to the processing drawing; S2: rough machining; S3: UT flaw detection; S4: drilling the bottom of the part according to the requirements of the drawing, The depth of drilling M16 is 50mm, the tooth depth is 35mm, and the chamfer of the hole is 45°; S5: Quenching and tempering, the hardness of the part after quenching and tempering is > 300; S6: Finishing of the outer conical surface, and a disc-shaped fixing seat is installed on the CNC machine tool , the part is fixed to the fixing seat through the first fastener through the drilling hole on its bottom surface, the diameter of the fixing seat is the same as the diameter of the bottom surface of the part, and the lower end of the part is fixed to the part by two pressing plates On the fixed seat, the middle part of the fixed seat is provided with an air expansion shaft, and a turning chip cover is installed on the drilling head of the CNC machine tool to process the conical surface on the upper part of the part; S7: packing and storing.
Description
technical field [0001] The invention relates to a manufacturing method of an inner taper sleeve. Background technique [0002] In the prior art, for figure 1 The blank shown is machined as figure 2 For the parts shown, the processing steps include A stage: rough turning + top finishing; B stage: rough turning + outer surface finishing; C stage: inner hole finishing. In B stage, because the part passes through the four-jaw chuck Fixed on the lathe, the high clamping force of the four-jaw chuck will cause deformation of the part after processing. In addition, because the conical surface of the part is processed, due to the thin wall thickness of the part, it is necessary to reduce the cutting amount of each cutting and reduce the Cutting feed, otherwise greater deformation will occur. Therefore, it is necessary to continuously adjust the state of the lathe during operation, and the processing efficiency is low. Contents of the invention [0003] The purpose of the presen...
