Abstract
The invention relates to a non-radial inclined hole machining device of a piston head, belonging to the technical field of workpiece machining. According to the machining device, an idler wheel support frame on an inclined base supports the piston head, a bearing on the idler wheel support frame is in contact with the outer surface of the piston head, and a drill jig body provided with fixed drill sleeves is fixed on a main bolt hole in the piston head through a positioning bolt. The machining device disclosed by the invention breaks through the history that only is a vertical numerical control machining center or horizontal milling or boring machine adopted in non-radial inclined hole machining. The machining device is simple in structure and convenient to use; a non-radial inclined hole is machined by a radial drill, so that the machining efficiency is improved and the production cost is reduced; by taking an instance that an 18-phi10 inclined water hole of a piston head of a G70 machine, 4 hours are needed in production per piece, the cost of unit production time is 70RMB/hour, and the machining cost just requires 280RMB which is greatly reduced compared with the cost of machining by using the vertical numerical control machining center and the horizontal milling and boring machine. The non-radial inclined hole machining device is suitable for machining of non-radial inclined holes of piston heads, is widely applied to non-radial inclined hole machining of similar parts and is also applicable to machining of bulk products.
Description
Technical field
The present invention relates to a kind of piston head non-static fields slant hole processing device, belong to the technical field of work pieces process.
Background technology
Machining hole on the face of cylinder, and processed hole axial line is not non-static fields inclined hole by the hole in the center of circle, the face of cylinder.At present, the processing of non-static fields inclined hole can adopt various processing equipment to complete.As: use vertical numerical control machining center.Upward, combustion chamber end face is positioned on work top down in piston head bottom surface, and after sucker clamping, centering center, main shaft polarization angle, input program data can be processed, and do not need other corresponding auxiliary mould.Use vertical numerical control Cutter Body Processing with Machining Center, advantage is that efficiency is high, precision is accurate; Shortcoming is that equipment investment is large, cause hour processing charges and operation processing charges high.To process G70 machine piston head 18-Φ 10 non-static fields inclined hole, single-piece work needs 4 hours man-hour, and working hour expense present price 600 yuan/hour, the processing charges of single-piece work operation are up to 2400 yuan.
Tradition non-static fields inclined hole processing mode also can adopt boring and milling machine with horizontal spindle.Still to process G70 machine piston head 18-Φ 10 inclined hole, first prepare a set of roller devices and bent plate and be placed in milling-boring machine workbench and fixing, workpiece is put on roller devices and clamps after the centering alignment of shafts, according to the position, 18-Φ 10 non-static fields oblique water hole that technique is given, get coordinate points and identify reference position.Rotary work turntable 50o, finds benchmark and position, hole aft-loaded airfoil accurately.Next hole can be bored after often processing a Kong Housong folder, transposition, centering, clamping.The advantage of this processing mode is that machining accuracy is higher, and shortcoming need be equipped with certain frock as bent plate and roller devices, but due to the unproductive time of centering, location, clamping longer, therefore working (machining) efficiency is not high.To process 18-Φ 10 non-static fields inclined hole, when single-piece work need in man-hour 5, working hour expense present price 250 yuan/hour, the processing charges of single-piece operation need 1250 yuan.
Summary of the invention
In order to overcome problems of the prior art, the invention provides a kind of piston head non-static fields slant hole processing device, to increase work efficiency, reducing production cost.
The technical solution used in the present invention is: a kind of piston head non-static fields slant hole processing device, by the rolling wheel support frame support piston head be arranged on inclined base, bearing on rolling wheel support frame and the exterior surface of piston head, model drilling body is fixed on the kingbolt hole of piston head by four bolts, and model drilling body is provided with fixing drill bushing; Angle between the trade union college plane of described inclined base and radial drill base horizontal plane is a, and the angle between the center line of non-static fields inclined hole and the trade union college plane of inclined base is b, and angle a and angle b sum equal an angle of 90 degrees.
Described model drilling body is provided with 18 fixing drill bushings.
The invention has the beneficial effects as follows: this piston head non-static fields slant hole processing device, by the rolling wheel support frame support piston head be arranged on inclined base, bearing on rolling wheel support frame and the exterior surface of piston head, model drilling body is fixed on the kingbolt hole of piston head by four bolts, and model drilling body is provided with fixing drill bushing.The history that the processing of non-static fields inclined hole can only adopt vertical numerical control machining center or boring and milling machine with horizontal spindle processing broken by this processing unit (plant).This processing unit (plant) structure is simple, easy to use, adopt radial drill processing non-static fields inclined hole, improve working (machining) efficiency, reduce production cost, to process the oblique water hole of G70 machine piston head 18-Φ 10, single-piece operation machining period needs 4 hours, working hour expense 70 yuan/hour, processing charges is only 280 yuan, processes compare expense and greatly reduce with vertical numerical control machining center and boring and milling machine with horizontal spindle.Be not only applicable to the processing of piston head non-static fields inclined hole, can be widely used in the processing of similar parts non-static fields inclined hole, and be applicable to the processing of bulk article.

Detailed description of the invention
Fig. 1,2,3 shows piston head non-static fields slant hole processing device, and it adopts the piston head 7 supported by rolling wheel support frame 6 to be arranged on inclined base 5, and piston head 7 is fixed in model drilling body 1 by bolt 3.With transposition handle 4 on piston head 7, model drilling body 1 is provided with 18 fixing drill bushings and 4 bolts.
When adopting technique scheme, first the bottom surface of inclined base 5 and radial drill base bolt are connected firmly, angle a between the trade union college plane of inclined base 5 and radial drill base horizontal plane is 50 degree of angles, and the angle b between the center line of non-static fields inclined hole 7a and the trade union college plane of inclined base 5 is 40 degree of angles.Be placed on by machining piston head 7 on inclined base 5, rely on two rolling wheel support frames 6 of inclined base 5 to be limited, the upper bearing 6a of rolling wheel support frame 6 contacts naturally with the outer surface of piston head 7.Finally model drilling body 1 is fixed on the kingbolt hole 7b of piston head 7 by four bolts 3, and determines the position of the large cooling water hole of piston head and through non-static fields inclined hole with this.Make sure to keep in mind the position in attention four positioning bolt holes and 18-Φ 55 hole.
Fix the position of drill bushing 2 with radial drill drill bit centering, circumference adjustment done by the location of workpiece transposition handle 4 be arranged on skirt section bolt hole 7, ensures that drill bit freely can be processed up and down in fixing drill bushing 2.Propose drill bit after drilling through a hole, renew processing with behind transposition handle 4 rotational workpieces alignment holes position.
