1. A tailstock for machine tools, applied to a lathe having an oblique surface and a slide rail longitudinally extending toward opposing lateral sides of the lathe along a direction of the oblique surface, the lateral sides of the lathe being defined with a specific axial direction, comprising:
a main body, having hollow hole; a lathe center unit, mounted inside the hollow hole of the main body by being parallel to the specific axial direction; a sliding base, fixed by locking to a side of the main body, having a slider at a side thereof respective to the slide rail, the slider engaging the slide rail in a sliding manner; and a clamping unit, inserted inside the sliding base, further comprising: a connection plate, inserted inside the main body, further having at least one positioning hole; at least one hydraulic rod, one end of the hydraulic rod being coupled with the slider while another end thereof contacts at a bottom surface of the main body; a plurality of loading devices, fixed to the hydraulic rod by sleeving in order about the hydraulic rod; a plurality of sleeves, ring-set individually about the hydraulic rod by contacting the respective loading devices;
wherein a surface of the loading device neighboring the connection plate further includes at least one position pin to mate the respective positioning hole of the connection plate. |
