Embodiment 1
[0035] Such as figure 1 As shown, a flexible sealed spindle center cooling device of the present invention is installed at the end of the machine tool spindle for positioning and clamping the workpiece 5 .
[0036] Such as Figure 2-3 As shown, a flexible sealing spindle center cooling device includes a flexible sealing part 1 and a clamping part 2 sleeved on the outer wall of the flexible sealing part 1. The flexible sealing part 1 is used to seal the inner hole entrance of the workpiece 5 and compensate the axis of the workpiece 5 Tolerance, the clamping part 2 is used to clamp the workpiece 5.
[0037] Such as Figure 4-5 As shown, the flexible sealing part 1 includes an outer sleeve 11 and an inner sliding sleeve 12 that are mutually fitted and can slide relative to each other. The outer sleeve 11 is fixedly connected with the clamping part 2, and a Elastic element 13, to realize the axial reset movement of inner sliding sleeve 12;
[0038] Wherein, the outer sleeve 11...
Embodiment 2
[0053] A lathe, comprising a pedestal, the pedestal is provided with a flexible sealing main shaft central cooling device.
[0054] The present invention possesses stronger versatility, with reference to figure 1 , assembled in the chuck structure of the lathe; the lathe is equipped with the flexible sealing spindle center cooling device of the present invention, which is used to process and manufacture pipes, so as to improve the clamping and positioning efficiency of workpieces, compensate the length tolerance of pipes and buffer axial vibration impact , improve the service life of the tool; especially for precision pipes with a large length-to-diameter ratio, it can significantly reduce labor intensity, improve processing efficiency and tool life, and is conducive to the development of basic manufacturing processes.
[0055] All features disclosed above, or steps in all methods or processes disclosed above, may be combined in any manner, except for mutually exclusive featur...
