A kind of stephanoporate thin wall lobe plate locating and machining frock, the frock is cuboid, and the corner of the frock is arranged to be used In the screwed hole at fixation four angles of lobe plate to be processed：First screwed hole 2, the second screwed hole 3, the 3rd screwed hole 4 and the 4th spiral shell Pit 5；The 5th screwed hole 6 and the 8th screw thread are uniformly arranged along the long side of frock between the first screwed hole 2 and the 4th screwed hole 5 Hole 9, the 6th screwed hole 7 and the 7th screwed hole are uniformly arranged along the long side of frock between the second screwed hole 3 and the 3rd screwed hole 4 8；Frock middle part setting three blind holes corresponding with first through hole, the second through hole, third through-hole in the middle of lobe plate, i.e., first Blind hole 10, the second blind hole 11, the 3rd blind hole 12；The frock left front arranges corresponding with lobe plate left front fourth hole the Four blind holes 13, the depth of each blind hole is 5mm, each blind hole diameter 1mm bigger than the diameter of corresponding aperture on lobe plate, described first Blind hole 10, the second blind hole 11 is respectively provided with the 9th screwed hole 14, the tenth screwed hole in the middle of the 3rd blind hole 12 and the 4th blind hole 13 15, the 11st screwed hole 16 and the 12nd screwed hole 17.

Compared with prior art, the beneficial effects of the utility model are：Clamping is simple, convenient and practical, high in machining efficiency, plus It is apt fixed.

1st, the clamping time of lobe plate is reduced using this utility model, on the premise of frock is changed without, completes to own Working procedure processing, improves machining accuracy, controls the machining deformation of stephanoporate thin wall lobe plate.

2nd, lobe plate positioning tool simple structure of the present utility model, practical, and clamping is simple, easy to use.

Specific embodiment

This utility model is described in further detail below in conjunction with the drawings and specific embodiments.

The schematic diagram of this utility model lobe plate positioning tool is as Figure 1-Figure 5.

(1) frock processing：To improve working (machining) efficiency, designed frock can simultaneously process two lobe plates.Frock is length Cube, to avoid repeating statement, only illustrates to the part that frock processes first block of lobe plate, and the processing second of frock is convex Wheel plate part is consistent with first lobe plate.Frock processes first piece of cam plate part, and its structure includes：With four angles of lobe plate Fixed corresponding screwed hole, i.e. the first screwed hole 2, the second screwed hole 3, the 3rd screwed hole 4, the 4th screwed hole 5.It is convex to reduce Wheel clamping deformation, in the middle part of lobe plate, is also provided with four screwed holes：That is the 5th screwed hole 6, the 6th screwed hole 7, the Seven screwed holes 8, the 8th screwed hole 9.The frock middle part is arranged and first through hole, the second through hole, third through-hole in the middle of lobe plate Corresponding three blind holes, i.e. the first blind hole 10, the second blind hole 11, the 3rd blind hole 12, the 4th blind hole 13, the depth of blind hole is 5mm, The frock left front arranges the 4th blind hole 13 corresponding with lobe plate left front fourth hole, and each blind hole diameter is than on lobe plate The big 1mm of diameter of corresponding aperture, when this four blind holes are the holes on machining cam plate, so that cutter top can be less than workpiece bottom, The hole for enabling lobe plate processes in place.Each blind hole middle setting has screwed hole, i.e. the 9th screwed hole 14, the tenth screw thread in frock The screwed hole 16 of hole the 15, the 11st, the 12nd screwed hole 17.

(2) lobe plate blank processing：According to the profile of stephanoporate thin wall lobe plate, it is rectangular slab 37 to select blank material. Eight through holes 36 corresponding with eight screwed holes of locating and machining frock periphery, eight through hole positions are processed on rectangular slab In cam periphery, four holes are 5mm from lobe plate blank material periphery in the middle of it, as shown in Figure 2.

(3) lobe plate inside hole machined：Lobe plate blank material is put in frock, is fixed lobe plate using eight screws In frock, Fig. 3, i.e. the first screw 18, the second screw 19, the 3rd screw 20, the 4th screw 21, the 5th screw the 22, the 6th are seen Screw 23, the 7th screw 24, the 8th screw 25, lobe plate need not carry out centering operation, because the lobe plate is overall processing, In the course of processing, lobe plate does not unclamp all the time, and the processing of lobe plate all process steps is completed in a frock.Lobe plate blank material On first through hole 26, the second through hole 27, third through-hole 28, using the end milling cutter of diameter 8mm, rotating speed 3000r/min, cutting Depth 0.3mm, feed speed 1500mm/min；Fourth hole 29, using the end milling cutter of a diameter of 3mm, rotating speed 5000r/ Min, cutting depth 0.2mm, feed speed 500mm/min；All through hole working depths are more than cam plate thickness 2mm.

(3) lobe plate circumference processing：Because lobe plate peripheral cam curve needs all processing, its cam curve model Placing can not have pressing plate and screw, now four screws, i.e. the 5th screw 22 in the middle of release, the 6th screw 23, the 7th screw 24, 8th screw 25, the screw on remaining four angle is motionless.Lobe plate is compressed using pressing plate 38, the platen shape is also cam, is pressed Than the peripheral little 2mm of the lobe plate after correspondence processing, recessed 1mm, there is four through holes, its position in the middle of pressing plate on pressing plate for plate periphery 39 Put corresponding with the blind hole center of lobe plate, using screw 1, screw 2 33, screw 3 34, screw 4 35, by pressing plate 38 and convex Wheel plate is compressed.Using the end milling cutter of a diameter of 6mm, rotating speed 4000r/min, cutting depth 0.2mm, feed speed 1000mm/ Min, completes cam contour processing.
