Problems solved by technology
[0003] (1) The processing is difficult and requires high technical experience for operators;
[0004] (2) The finished product rate of the product is low;
[0005] (3) The machining of the traditional slender shaft is mainly based on the accuracy of the clamping reference (center hole), which is difficult to obtain, and the clamping method based on the center hole does not fully position the workpiece, so the final processed thin Long axis accuracy is difficult to guarantee

Embodiment Construction
[0044] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0045] A production line for processing slender shafts, including a slider wire cutting machine that processes a slider structure for positioning at both ends of a workpiece 1 in the first process, and stretches and positions the slider structure in the second process A lathe that processes the workpiece 1 segment by segment and a grinder that processes the workpiece 1 in the EDM fluid in the third process. Such as figure 1 As shown, the slider structure includes a boss 41 at the center of the end of the workpiece 1, two straight faces 42 are symmetrically arranged on opposite sides of the boss 41, and two straight faces 42 are arranged symmetrically on opposite sides of the boss 41. There are two gaps, and the gap...

The invention relates to a production line for machining spindly shafts. The production line comprises a drawing head line cutting machine for machining drawing head structures for positioning a workpiece at two ends of the workpiece in a first process, a lathe for machining the workpiece section by section after the workpiece is drawn and positioned by the drawing head structures in a second process, and a grinding machine for machining the workpiece which is drawn and positioned by the drawing head structures by soaking the workpiece in an electric spark solution in a third process. The production line for machining the spindly shafts has the beneficial effects that a clamping method in the conventional spindly shaft machining process is firstly changed, namely the drawing head structures which are subsequently used for clamping and positioning during machining of the lathe and the grinding machine are machined at the two ends of the workpiece in the beginning through a line cutting manner; the workpiece is clamped by the drawing head structures in the machining processes of the lathe and the grinding machine; through a drawing force type clamping manner, the stability of the workpiece is greatly improved; the workpiece is high in radial strength, so that the workpece is convenient to machine; in addition, a manner of machining through grinding of the grinding machine in the conventional spindly shaft machining process is changed into an electrosparking manner, so that the machining accuracy is improved.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a production line for processing slender shafts. Background technique [0002] The processing of slender shafts with relatively large shaft diameters has always been a difficult problem in the field of metal processing. The main reasons are as follows: [0003] (1) The processing is difficult and requires high technical experience for operators; [0004] (2) The finished product rate of the product is low; [0005] (3) The machining of the traditional slender shaft is mainly based on the accuracy of the clamping reference (center hole), which is difficult to obtain, and the clamping method based on the center hole does not fully position the workpiece, so the final processed thin Long-axis accuracy is difficult to guarantee. Contents of the invention [0006] To sum up, in order to solve the deficiencies of the prior art, the technical problem to be solved by the present...
