The specific embodiment
As shown in Figure 1, the two-way deburring chamfering of band protective jacket gang tool (being called for short " gang tool ") comprises cutter hub 1, cutter suitable for reading 9, end opening cutter 10 and little angle cutter 12.
As shown in Figure 5, cutter 9 suitable for reading is roughly a slice shape, respectively is formed with declivous cutting edge 92, two cutting edges 92 in the lower end, both sides of lamellar body and inwardly receives downwards, and there is elongate slots 91 at the center of lamellar body.
Like Fig. 3 and shown in Figure 4, cutter hub 1 is formed with the last slot 90 that runs through both sides vertically, sees figures.1.and.2 simultaneously, and cutter 9 suitable for reading is inserted in the slot 90, and the screw that lock-screw 8 passes on the cutter hub 1 is fixed on cutter suitable for reading in the slot 90.There is axial long hole 101 upper end of cutter hub 1, and there is screwed hole 102 lower end of axial long hole 101, and adjustment double-screw bolt 5 is inserted into the screwed hole 102 from axial long hole 101 and is threaded with screwed hole 102, and the lower end of adjustment double-screw bolt 5 and the upper end of cutter suitable for reading 9 are replaced.Adjustment double-screw bolt 5 can be when cutter 9 suitable for reading be installed the axial location of assist location cutter 9 suitable for reading on cutter hub 1.
The blade 92 of the both sides of cutter 9 suitable for reading is the outsides that are positioned at elongate slots 90, so that cutting workpiece.
As shown in Figure 6, end opening cutter 10 comprises blade 10a, the 10b of two symmetries, and two blade 10a, 10b respectively have circular hole, so that securing member passes, two circular hole coaxial lines are provided with, and with this axis symmetry, the outside of each blade 10a, 10b is a blade 109.Referring to figs. 1 through Fig. 4, cutter hub 1 is formed with the following slot 100 that runs through both sides vertically simultaneously, and following slot 100 is inserted in down in the slot 100.Lock-screw 11 passes the screw on the cutter hub 1 and passes two blade 10a, the last circular hole of 10b; Two blade 10a, 10b are fixed on the cutter hub 1, and blade 10a, the 10b of two symmetries are symmetry axis with lock-screw 11 promptly, and two blade 10a, 10b can be around lock-screw 11 swings; Be provided with spring 103 between two blade 10a, the 10b; Spring 103 keeps the blade of two blade 10a, 10b at a distance of preset distance, and this distance equals the aperture (perhaps being slightly larger than) of workpiece, with the inboard burr in hole of eliminating workpiece.
As shown in Figure 7; Little angle cutter 12 is a blade; Have elongated hole 123, have in both sides to center and downward-sloping two symmetrical groups blade 121,121 and 122,122, wherein one group of blade 121,121 is positioned at the bigger conical both sides of a minimum diameter; Another group blade 122,122 is positioned at the less conical both sides of another minimum diameter, can adapt to the different aperture of more internal diameters through two groups of blades.Little angle cutter 12 is mainly used in the chamfering of the aperture of product.
Continue to see figures.1.and.2, the periphery of cutter hub 1 is with protective jacket 7, and protective jacket 7 has blocked the blade of cutter suitable for reading 9, end opening cutter 10 at least.The upper end of cutter hub 1 also is fixed with thrust bearing 4 through dog screw 3; Be provided with spring 6 between thrust bearing 4 and the protective jacket 7; Spring 6 plays the effect in the position of the blade that has blocked cutter suitable for reading 9, end opening cutter 10 at least of the initial position that keeps protective jacket 7 on the one hand; Quantitatively play the effect of the blade that exposes cutter 8 suitable for reading on the other hand; Therefore be that spring 6 is arranged between protective jacket 7 and the thrust bearing 4, controlled the distance of protective jacket 7, therefore controlled the amount that protective jacket 7 exposes the blade of cutter 9 suitable for reading near thrust bearing 4.
Screw 3 penetrates and connects cutter hub from the periphery of ring (trimmer) 2 of thrust bearing 4; Thereby will go up ring 2 is positioned on the cutter hub 1; Unclamp dog screw 3, ring 2 in the rotation (there is screw thread in the outside of cutter hub 1, on encircle 2 be threaded) with cutter hub 1; Thereby the position of scalable thrust bearing 4, thereby regulate the amount that protective jacket 7 exposes the blade of cutter 9 suitable for reading.
See figures.1.and.2, the installation process of gang tool is following:
1. insert 8 lockings of cutter hub 1 usefulness lock-screw to cutter 9 suitable for reading;
2. inserting cutter hub 1 usefulness dog screw 11 to two end opening cuttves 10 screws in fixing;
3. insert cutter lock-screw 14 lockings in the little angle of cutter hub 1 usefulness to little angle cutter 12;
4. put into positioning security cover 7 cutter hub 1, put into buffering and return out spring 6 and be inserted in thrust bearing 4 again, screw in trimmer 2 locking positioning screws 3;
Continue to see figures.1.and.2, the adjustment process of gang tool is following:
1. going up of rotary thrust bearing 4 encircles 2, and the distance between control thrust bearing 4 and the positioning security cover 7 guarantees the chamfering size of 9 pairs of workpiece of cutter suitable for reading;
2. the size of transposing end opening cutter elastic spring 13 confirms that what of burr workpiece removed;
3. the distance of adjusting both sides blade and cutter hub 1 head end two intersection points of little angle cutter 12 is controlled the chamfering size of workpiece aperture.
The operation principle of gang tool is: the rotation combination cutter that will adjust the chamfering amount stretches into and utilizes in the workpiece hole that cutter suitable for reading carries out an end face chamfering, the deburring of end opening cutter, the edge of a knife carries out the other end chamfering down, and the little angle cutter on gang tool top is to the quantitative chamfering of aperture (if being necessary) then.
Previous embodiment has following advantage:
1. changing two-way (just put and put upside down) chamfering deburring is unidirectional (just put, put upside down arbitrarily) processing, reduces labour intensity, has improved production efficiency;
2. quantitatively chamfering has further been guaranteed the processing of brake disc aperture chamfering, deburring can meet the requirement of product drawing better;
3. the application of the protective jacket on the gang tool has avoided producing in the production process hidden danger of industrial injury;
4. the carbide chip that utilizes enterprise to scrap is made, and cost is low.
