Accompanying drawing explanation
Fig. 1 is the schematic diagram of process allowance in mechanically cutting method of the present invention;
Fig. 2 is the part blank of abnormity sheet metal component of the present invention scheme of installation on lathe.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition Word can be implemented according to this.
As depicted in figs. 1 and 2, the present invention provides a kind of mechanically cutting method of abnormity sheet metal component process allowance, described different The part blank 2 of shape sheet metal component is by the first horizontal part 3, first surface portion 4, rake the 5, second curved face part 6 and the second level The Z-shaped structure that portion 9 is connected in sequence, and described first horizontal part 3 is positioned at of a relatively high position, and described second horizontal part 9 are positioned at relatively low position, and described method includes:
Step one, bottom frock 10 being installed on lathe, described bottom frock 10 has the first horizontal plane 11, inclined plane 12 and second horizontal plane 13, described part blank 2 is placed on the frock of described bottom, and makes described first horizontal plane 11 Fitting with described first horizontal part 3, described inclined plane 12 is fitted with described rake 5, described second horizontal plane 13 and described the Two horizontal parts 9 are fitted, and support so that described bottom frock provides for described part blank.Bottom frock provides for part blank Support, make part blank be stably placed on lathe, it is ensured that construction precision.Bottom installation during frock, need to beat table centering, Gu Fixed tight.
Step 2, one locating piece of offer have a horizontal bottom 14 and four sides, and wherein first side 16 is Curved surface, is second side with the side adjacent with first side 16, with the side relative with first side 16 for the 3rd Individual side 15;Described locating piece 1 is arranged on described part blank 2, and makes described horizontal bottom 14 with described second Horizontal part 9 is fitted, and makes first side 16 fit with described second curved face part 6, so that second side and described abnormity metal plate The theory limit, both sides of gold part is parallel, makes the 3rd side parallel with the front theoretical limit 7 of described abnormity sheet metal component and rear theoretical limit 8. Locating piece is designed with a curved surface and three vertical sides, the second curved face part of curved surface with part blank is fitted completely, thus Make the relative position between locating piece with part blank fix and accurately, at subsequent working-up stages, be determined by the position of locating piece Put the position on each theoretical limit being assured that out abnormity sheet metal component, and then realize accurately processing.
Step 3, offer patch shape pressing plate, the lower surface of described patch shape pressing plate and the shape of the upper surface of described part blank Unanimously, a pair patch shape pressing plate is arranged on described part blank, makes a pair patch shape pressing plate fit with described part blank, and A pair patch shape pressing plate is distributed in the both sides of described locating piece.Patch shape pressing plate is for further retaining element blank, makes part hair The position of base immobilizes.The shape of patch shape pressing plate is consistent with part blank, such that it is able to be completely against on part blank, changes Kind fixed effect.Additionally, can also arrange a common pressing plate on patch shape pressing plate, this common pressing plate is re-pressed against pasting shape pressure On the upper surface of plate, the most fixing patch shape pressing plate.
Step 4, in machine tool control system, set up a coordinate system, and determine described locating piece second side and Position in described coordinate system, 3rd side, according to theoretical size and the chi of described locating piece of described abnormity sheet metal component Very little, the distance value between second side and theory limit, both sides and the 3rd side are set in advance in described machine tool control system Face distance value respectively and between front theoretical limit 7, rear theoretical limit 8, described machine tool control system according to second side described Position in coordinate system and second side distance value respectively and between theory limit, both sides controls cutter 5 to described part hair The dual-side of base cuts, according to the 3rd side in the position in described coordinate system and the 3rd side respectively with front Distance value between theoretical limit 7, rear theoretical limit 8 controls cutter 5 and cuts front and the back of described part blank, thus Processing obtains the described abnormity sheet metal component of theoretical size.When determining second side of locating piece and the concrete of the 3rd side Position, and owing to the theoretical size of abnormity sheet metal component is previously known, then just can pre-set second side and arrive The distance value on theory limit, both sides and the 3rd side are to front theoretical limit 7, the distance value on the most theoretical limit 8.After setting, lathe control System processed can control cutter and cut four sides of part blank, will be beyond second side, the 3rd side phase Answer the part outside distance value to cut away (part cut i.e. process allowance 6), i.e. can obtain the abnormity of coincidence theory size Sheet metal component.
Above-mentioned " front " and " afterwards " correspond respectively to the left side in Fig. 1 and Fig. 2 and right side, and above-mentioned " both sides " are then corresponding to figure Outside paper in 1 and Fig. 2 and inside paper.
Part blank has been carried out stably fixing and has been precisely located by the present invention, therefore, and the special-shaped metal plate obtained by processing The precision of gold part is high, steady quality.
In a preferred embodiment, in the mechanically cutting method of described special-shaped sheet metal component process allowance, described patch The edge of the lower surface of shape pressing plate is arranged with blunt form, thus prevents in compaction process the upper surface at part blank to extrude Impression.
In a preferred embodiment, in the mechanically cutting method of described special-shaped sheet metal component process allowance, described cutter Tool 5 is ball cutter.When processing Z-direction hypotenuse, coming into contact with part blank in working angles, cutting force is little, cutting vibration Little.
In a preferred embodiment, in the mechanically cutting method of described special-shaped sheet metal component process allowance, the described end The manufacturing process of portion's frock 10 is: first welded by multiple sheet materials, then mills out the first horizontal plane, inclined plane and the second horizontal plane.
In a preferred embodiment, in the mechanically cutting method of described special-shaped sheet metal component process allowance, described different Shape sheet metal component is allotype aluminum alloy sheet metal component.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed Using, it can be applied to various applicable the field of the invention completely, for those skilled in the art, and can be easily Realizing other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit In specific details with shown here as the legend with description.
