Problems solved by technology
[0002] In the existing mechanism, there are many parts with coaxiality requirements for the holes at both ends, which are widely used. During the use of this type of assembly, a certain degree of coaxiality is required to meet the requirements of use. If the error is too large, not only It cannot meet the requirements of use, and will affect the working efficiency and working life of the mechanism. This requires the coaxiality of the parts to be guaranteed during the processing. In the existing processing technology: some special machine tools are used for processing, and some are processed in two parts No matter which processing method is used, the processing cost of the former is high and the investment is large. Although the cost of the latter is low, the processing accuracy is too low to guarantee the processing accuracy of the parts.

Embodiment Construction
[0009] as attached figure 1 As shown, the method for processing parts with coaxiality requirements on the two ends of the lathe is composed of an ordinary lathe and a tool holder fixture, and is characterized in that the tool bar 2 passes through the hole of the part 4, and the left end of the tool bar 4 It is tightened by the lathe chuck 1, and the right end is floatingly connected with the lathe tailstock 8 through the rolling body 7. The left tool 3 and the right tool 6 are respectively mounted on the tool bar 2, and the left tool 3 is located on the left side of the part 4. On the side, the right tool 6 is located on the right side of the part 4, and the base plate 9 is positioned under the part 4, and it is pressed by the pressing device 5, and the pressing device 5 is fixed on the supporting plate 10.
[0010] The lathe may be a numerically controlled lathe.
[0011] The invention has the advantages of simple structure and convenient operation, and can guarantee the des...
