Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of fixture, is specifically related to a kind of hanger outline milling special fixture.
Background technology
At present, CNC milling machine requires chamfering 2mm * 45 ° when as depicted in figs. 1 and 2 hanger part of processing, and other operations of part are completed, and two large faces process, two boring completion of processing of hole, external arc surplus 2-3mm.Require the peripheral circular arc of processing and chamfering on CNC milling machine, external arc limit clamping once can be completed processing, but chamfering needs positive and negative twice clamping just can complete.There is following problem in conventional clamping process: 1, locate because part adopts two centre bores, so centering is very inconvenient; 2, the crudy of tow sides chamfering can't guarantee; When 3, parts batch is produced, waste time and energy, production efficiency is low.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of hanger outline milling special fixture is provided, it can make part positioning and clamping to be processed easy, quick, accurate, part processing precision is high, reasonable in design, simple in structure, versatility is good, manufacture craft is simple, and production cost is low, be convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hanger outline milling special fixture, comprise backing plate and T-shaped slot bolt, it is characterized in that: described backing plate is provided with installing hole one and installing hole two, in described installing hole one, alignment pin one is installed, in described installing hole two, alignment pin two is installed, two described T-shaped slot bolts pass respectively alignment pin one and alignment pin two, two described T-shaped slot bolt tops are provided with nut, are provided with pressing plate between two described nuts and alignment pin one and alignment pin two.
Above-mentioned hanger outline milling special fixture is characterized in that: within the outline of described backing plate all is positioned at the outline of part to be processed.
Above-mentioned hanger outline milling special fixture, it is characterized in that: described pressing plate is the opening pressing plate.
The utility model compared with prior art has the following advantages:
(1) this hanger outline milling special fixture can make part positioning and clamping to be processed easy, quick, accurate, effectively guarantees outline and the chamfer machining precision of part.
(2) this hanger outline milling Special Clamps Design is very reasonable, and simple in structure, and the scope of application is extensive, and versatility is good.
(3) this hanger outline milling special fixture manufacture craft is simple, and a lot of parts all are convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
