Embodiment Construction
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] like Figure 1-2 As shown, a tooling fixture for CNC finishing includes a base 1, a bar 2 is arranged on the upper end of the base 1, and the bar 2 is positioned and clamped at the upper end of the base 1, which is convenient for subsequent finishing; There are two positioning grooves 21 symmetrically opened on the circle. By positioning the two positioning grooves 21, compared with the prior art, the clamping force is used to...

The invention discloses a CNC finishing method and a tooling fixture, belonging to the field of machining; a tooling fixture for CNC finishing comprises a base, a centering mechanism and a clamping mechanism; The upper end of the base is provided with a centering mechanism and an engaging mechanism, and two first clamping blocks capable of synchronous reverse movement are arranged in the centering mechanism, and a universal ball is arranged on the inclined surface of the first clamping block. Two card board assemblies capable of synchronous reverse movement are provided, and a card board and a mounting plate that are elastically connected to each other are arranged in the card board assembly, so that the card board is engaged with the positioning groove, compared with the prior art directly through the In terms of clamping force to limit the rotational freedom of the bar, it can more effectively and stably prevent the bar from being clamped, and under the action of the cutting force, rotation will occur and affect the machining accuracy; a CNC finishing method includes: Grooving, positioning clamping, machining and tailing removal.
Description
technical field [0001] The invention belongs to the field of machining, and in particular relates to a CNC finishing method and a tooling fixture thereof. Background technique [0002] CNC is also known as CNC milling machine. With the continuous development of science and technology, CNC milling machines are more and more widely used in the field of machining; CNC milling machine is a CNC machine tool with strong processing functions. Units, etc. are produced on the basis of CNC milling machines and CNC boring machines, both of which are inseparable from the milling method; because the CNC milling process is the most complicated and the technical problems to be solved are the most, people are researching and developing CNC systems and When using automatic programming language software, milling has always been the focus; [0003] In the prior art, when the CNC milling machine processes the bar, the bar is fixed by the clamping force, and the static friction force generated ...
