Supporting base of lathe for two-end-face floating positioning of machined part and using method thereof

Abstract

The invention discloses a supporting base of a lathe for two-end-face floating positioning of a machined part and a using method of the supporting base. The supporting base is provided with a supporting base solid body, a floating supporting mechanism is arranged in the supporting base solid body, therefore, when the supporting base supports and positions the first end face of the machined part, the floating supporting mechanism is added and used for carrying out floating supporting on the second end face of the special-shaped part for assisting, and the second end face and the first end faceof the machined part has the height difference within the certain range. Since the first end face is precisely positioned, and the second end face is supported in a floating mode, it can be ensured that the first end face is firmly positioned, the second end face always makes close contact with a clamp, it is ensured that the second end face of the part is not in a suspended state in the machiningprocess, the turned position of the second end face is smooth and flat, and vibration knife lines disappear.

Description

technical field [0001] The invention relates to the technical field of support mechanisms, in particular to a support seat for floating and positioning a workpiece with double ends of a lathe and a method for using the same. Background technique [0002] When processing most special-shaped parts with a ratio of large and small diameters greater than 3, the processing requirements can be met by positioning the small end face (first end face) during turning, but it is easy to make the large end face (second end face) of the entire part in a cantilever state; For gears with a diameter ratio greater than 3 between the large and small end faces, when finishing the end face, in order to ensure that the positioning surface is consistent with the spline drawing process, the small end face is always positioned, so that when the large end face is finished, the vibrating knife pattern is obvious, affecting the surface of the part quality. [0003] In the prior art, most gear manufactu...

[0002] When processing most special-shaped parts with a ratio of large and small diameters greater than 3, the processing requirements can be met by positioning the small end face (first end face) during turning, but it is easy to make the large end face (second end face) of the entire part in a cantilever state; For gears with a diameter ratio greater than 3 between the large and small end faces, when finishing the end face, in order to ensure that the positioning surface is consistent with the spline drawing process, the small end face is always positioned, so that when the large end face is finished, the vibrating knife pattern is obvious, affecting the surface of the part quality

[0003] In the prior art, most gear manufacturers use imported double-end hydraulic floating positioning fixtures for double-end positioning, but the manufacturing cost of this kind of fixture is relatively high
