Problems solved by technology
[0002] When many shafts or similar shaft parts are processed, they must be positioned by the center holes at both ends, and usually an axial force needs to be applied to both ends of the part. Generally, the top is clamped, and the top is made to fit the center hole of the part before processing, but When the part is a slender shaft or a part that is easy to bend, it is easy to make the part elastically bend during the clamping process, which makes it difficult to control the dimensional accuracy and shape tolerance of the part, which affects the machining accuracy of the part

Embodiment Construction
[0010] A clamping method for shaft parts, such as figure 1 As shown, it is characterized in that: first measure the distance between the two ends of the workpiece 1 in a free state, and then put the workpiece between the two tops 5, one of the tops is mounted on the movable top seat 6, and the flanges 2 are mounted on both ends of the workpiece. , tighten the nuts 8 respectively, so that the tip fits the center hole of the workpiece, measure the distance between the two ends of the workpiece, and compare it with the distance between the two ends of the workpiece in the free state, adjust the position of the movable center seat 6, so that the distance between the two ends of the workpiece is the same as that of the free state. In this state, the distances between the two ends of the workpiece are consistent, and the movable center seat 6 is fixed to process the workpiece.
[0011] Specific embodiments of the present invention are as follows (as figure 1 Shown): A. Install flan...

The invention relates to a method for clamping axle element, wherein it is characterized in that: first, measuring two end distance of work piece at free state; putting work piece between two top sharps, while one is mounted on movable top sharp base; two ends of work piece are mounted with flange discs fixed via nuts to contact the sharp with central hole; measuring two ends distance compared with free state, adjusting position of movable top sharp base, to correct them same, fixing movable top sharp, and processing the work piece. The invention can avoid flexible curvature in treatment to improve accuracy. And the distance measurement can utilize laser measurer.
Description
technical field [0001] The invention belongs to the category of mechanical processing methods, in particular to a clamping method for shaft parts. Background technique [0002] When many shafts or similar shaft parts are processed, they must be positioned by the center holes at both ends, and usually an axial force needs to be applied to both ends of the part. Generally, the top is clamped, and the top is made to fit the center hole of the part before processing, but When the part is a slender shaft or a part that is easy to bend, it is easy to cause the part to be elastically bent during the clamping process, which makes it difficult to control the dimensional accuracy and shape tolerance of the part and affects the machining accuracy of the part. Contents of the invention [0003] The purpose of the present invention is to provide a clamping method for shaft parts that is simple and reasonable, can effectively control the elastic bending of the slender parts after clampi...
