A kind of boring machine fixture
The present invention relates to a kind of Workpiece machining apparatus, relate in particular to a kind of boring machine fixture of processing water pump.
Traditional mechanical processing technique, the large plane of milling, mistake water endoporus operation are all unified lathe processing, and hand labor intensity is large, and scroll chuck is easily damaged, and product easily flies out, and exists potential safety hazard large.Processing a part needs for a long time.As large milling plane, mistake water endoporus operation are split and come, water endoporus is crossed in general boring machine fixture boring, cannot guarantee again the axiality of its position and blank position of bearings profile.Cause processing the large plane of water pump milling, to cross water endoporus process efficiency very low, and wastes a large amount of human and material resources and time.Particularly large pump need to be processed, and general factory, in the time of the large plane of processing and milling, mistake water endoporus operation, all adopts large lathe processing, and the problem of this way maximum is that chuck is large, is manually difficult to clamp, and centrifugal force is large, and efficiency is low.The precision many deficiencies such as being difficult to assurance that are affected of processing, are difficult to meet the need of market.
Summary of the invention
The present invention, in order to overcome above-mentioned defect of the prior art, provides a kind of simple and reasonable, easy to operate, is easy to the boring machine fixture of clamping.
In order to achieve the above object, the invention provides a kind of boring machine fixture, comprising:
Frock base plate;
Some support bars, it is located at the upper surface of described frock base plate;
Frock panel, it is located at the end of described support bar, parallel with described frock base plate, has datum hole at described frock panel surface, and the aperture of described datum hole is greater than the aperture in the hole of required processing work;
Guide rod, it is located between described frock base plate and described frock panel, parallel with described support bar;
Sliding panel, it is provided with the hole corresponding with described guide rod, and one end of described guide rod is fixedly connected with described frock base plate through the hole of described sliding panel; And
Cylinder, the piston rod of described cylinder is connected with described sliding panel;
Wherein, be provided with the profile centralized positioning cover corresponding with described frock panel datum hole on described sliding panel, described profile centralized positioning cover inside is conical.
In technique scheme, described profile centralized positioning cover inside is conical, and the gradient of described conical wall is 45 degree.
In technique scheme, on described guide rod, be provided with guide pin bushing, the lower end of described guide pin bushing is fixedly connected with described sliding panel upper surface.
In technique scheme, the gap between described guide pin bushing and described guide rod is 0.05mm～0.1mm.
In technique scheme, described profile centralized positioning cover inner wall smooth.
In technique scheme, described cylinder is by Manual gas valve control.
Beneficial effect of the present invention is as follows: boring machine fixture of the present invention comprises frock base plate, support bar, frock panel, guide rod, sliding panel and cylinder, wherein, on frock panel, be provided with profile centralized positioning cover, and profile centralized positioning cover inside is conical, workpiece is placed in profile centralized positioning cover, use air cylinder lifting sliding panel, workpiece contacts with the lower surface of frock panel, datum hole on the corresponding frock panel in hole of required processing, boring machine fixture of the present invention is used for processing water pump, can guarantee the axiality of the interior water hole position of water pump and blank position of bearings profile, realize efficiency high, labour intensity is little.

Wherein, 1, cylinder; 2, frock panel; 3, Manual gas valve; 4, guide rod; 41, the first guide rod; 42, the second guide rod; 5, support bar; 6, guide pin bushing; 61, the first guide pin bushing; 62, the second guide pin bushing; 7, profile centralized positioning cover; 8, sliding panel; 9, frock base plate; 10 datum holes; 11, hole; 111, the first hole; 112, the second hole.
The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.
As shown in Figure 1, a kind of boring machine fixture, comprising:
Frock base plate 9; Four support bars 5, it is located at the upper surface of described frock base plate 9; Frock panel 2, with screw and nut, frock panel 2 is fixed on to the upper end of support bar 5, frock panel 2 is parallel with frock base plate 9, have datum hole 10 on described frock panel 2 surfaces, the aperture of described datum hole 10 is greater than the aperture in the hole of required processing water pump, and the boring cutter on boring machine carries out Boring by datum hole to water pump, two guide rods 4, it is located between described frock base plate 9 and described frock panel 2, parallel with described support bar 5; Sliding panel 8, is provided with the first hole 111 and the second hole 112 at the panel of sliding panel 8, and guide rod 41 is fixedly connected with frock base plate 9 through the first hole 111, and guide rod 42 is fixedly connected with frock base plate 9 through the second hole 112; And cylinder 1, comprise two cylinders 1, be located at the left and right sides on frock panel 2, the piston rod of described cylinder 1 is connected with described sliding panel 8, to control sliding up and down of sliding panel 8; Wherein, on described sliding panel 8, be provided with the profile centralized positioning cover 7 corresponding with described frock panel 2 datum holes 10, described profile centralized positioning is overlapped 7 inside and is conical, the gradient of described conical wall is 45 degree, inner wall smooth, and profile centralized positioning cover 7 is put in the one end that water pump is to circular cone shape, can well contact fixing with profile centralized positioning cover 7, in the time of bore hole, be difficult for being offset, add and be convenient to man-hour water pump to put into and take out, easy and simple to handle.
On described the first guide rod 41, cover has the first guide pin bushing 61, on the second guide rod 42, cover has the second guide pin bushing 62, the lower end of described the first guide pin bushing 61 and the second guide pin bushing 62 is fixedly connected with described sliding panel 8 upper surfaces, gap between guide pin bushing 6 and described guide rod 4 is 0.05mm～0.1mm, makes guide pin bushing 6 be easier to slide on guide rod 4.
Described cylinder 1 is by the activity of Manual gas valve 3 control cylinders 3, and Manual gas valve 3 is located on frock panel 2.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in description and embodiment, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend of describing.
