Abstract
The utility model relates to an involute milling machine of a cam shaft, comprising a machine body, a machine frame and a tail seat, wherein two ends of the machine body are respectively fixed with the machine frame and the tail seat; the machine frame is internally connected with a main shaft which is connected with a power transmission mechanism; the machine frame is also internally provided with a dividing spindle which is connected with the main shaft by a gear transmission mechanism; the front end of the dividing spindle is connected with a profiling; and one side of the machine frame is provided with a cutter disc linked with the profiling. Under the driving of the power transmission mechanism, the cam shaft and the profiling rotate simultaneously, the cutter disc linked with the profiling executes copying movement, and the involute contour of the cam shaft is milled by the copying movement of the cutter disc. As the transmission ratio of the main shaft and the dividing spindle is 1/2, the cam shaft only rotates by semicycle when the profiling rotates by one cycle, the involute contour of one side is processed; and when the profiling rotates by one cycle again, the involute contour of the other side is processed, and the involute milling machine is positioned without being stopped, thus guaranteeing the symmetry degree of the processed involute contour, improving the working efficiency and simultaneously also reducing the labor intensity.
Description
Technical field
The utility model relates to a kind of involute milling machine of camshaft, contains fuselage, frame, tailstock, and described fuselage two ends are fixed with frame and tailstock respectively, are connected with main shaft in the frame, and described main shaft is connected with power drive mechanism, and the outer side edges of frame is provided with guide rail.
Background technology
At present, in the Pneumatic braking system of most of domestic automobile and the external automobile of part, all adopt the wheel drag of cam actuated, and brake-toggle shaft all adopts traditional processing method during fabrication, promptly on plain-milling machine, respectively the involute contour of camshaft both sides is processed,, caused the involute contour symmetry low precision of both sides owing to be to adopt twice location processing, process velocity is slow, the labor strength height.
The utility model content
The technical problems to be solved in the utility model provides a kind of involute milling machine of camshaft that can improve both sides involute contour symmetry precision and working (machining) efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of involute milling machine of camshaft, contain fuselage, frame, tailstock, unit head and cutterhead, described fuselage two ends are fixed with frame and tailstock respectively, be connected with cutterhead on the described unit head, be connected with main shaft in the described frame, described main shaft is connected with power drive mechanism; Its innovative point is: dividing spindle also is housed in the described frame, and described dividing spindle is connected with main shaft by gear drive; The front end of described dividing spindle is connected with pattern; The sidewall of described frame is provided with vertical guide rail, is connected with slide block in the described vertical guide rail, and the lower surface and the pattern of described slide block are rigidly connected, and sidewall is fixedlyed connected with unit head.
Further, the gearratio of described main shaft and dividing spindle is 1/2.
Advantage of the present utility model is: during use, camshaft to be processed is connected on the thimble of main shaft and tailstock, under the drive of power drive mechanism, camshaft and pattern rotate simultaneously, the slide block that drops on simultaneously on the pattern drives unit head upper tool pan execution forming movement, moves the involute contour of milling camshaft by the profiling of cutterhead.Because the gearratio of main shaft and dividing spindle is 1/2, camshaft only changeed half-turn when pattern rotated a circle, process the involute contour of a side, after pattern rotates a circle again, process the involute contour of opposite side, guaranteed the symmetry of the involute contour that processes, and in this process, only need carry out one-time positioning, also reduce labour intensity when increasing work efficiency.
Description of drawings
Fig. 1 is the structural representation of involute milling machine of camshaft of the present utility model.
Fig. 2 is the side view of involute milling machine of camshaft of the present utility model.
The specific embodiment
Embodiment as shown in Figure 1, 2, contains fuselage 1, frame 2, tailstock 3, main shaft 4, decelerator 5, motor 6, worm gear 8, dividing spindle 9, pattern 14, vertical guide rail 15, slide block 16, unit head 17, cutterhead 18, the support of bearing 19, bearing 20.
The two ends of above-mentioned fuselage 1 are fixed with frame 2 and tailstock 3 respectively, in frame 2, be connected with main shaft 4, described main shaft 4 is connected with power drive mechanism, power drive mechanism comprises decelerator 5 and motor 6, motor 6 is connected with decelerator 5 by belt transmission 7, and described decelerator 5 is connected with worm gear 8 on the main shaft 4.All be connected with the thimble 21,22 of fixation workpiece on main shaft 4 and the tailstock 3.
Also be connected with dividing spindle 9 in the frame 2 above main shaft 4, on the described dividing spindle 9 dividing gear 11 be housed, front end is connected with pattern 14.This dividing spindle 9 is connected with main shaft 4 by gear drive, its concrete structure is: be provided with the axle 12 of passing a bridge between main shaft 4 and dividing spindle 9, driving gear 10 is housed on the main shaft 4, be connected with dividing gear 11 on the dividing spindle 9, this dividing gear 11 is connected with driving gear 10 by the carrier gear 13,25 of the axle 12 of passing a bridge, thereby realize the interlock of dividing spindle 9 and main shaft 4, i.e. the interlock of the pattern 14 of the camshaft of main shaft 4 and dividing spindle 9.
As shown in Figure 1, 2, the sidewall of frame 2 is provided with vertical guide rail 15, is connected with slide block 16 in the described vertical guide rail 15, and the lower surface of this slide block 16 and pattern 14 are rigidly connected, and its sidewall is fixed with unit head 17, and cutterhead 18 is equipped with in the bottom of described unit head 17.Slide block 16 is given in curved surface power transmission by pattern 14, makes the cutterhead 18 of fixedlying connected with slide block 16 carry out forming movement.In order to reduce the frictional force of pattern 14 and slide block 16, we are fixed with the support of bearing 19 in the lower surface of slide block 16, are connected with bearing 20 on the support of bearing 19, realize like this having reduced frictional resistance with regard to the curved surface of pattern 14 and being slidingly connected of bearing 19.
In order to realize milling smoothly to camshaft both sides involute contour, we are 1/2 with the gearratio of main shaft 4 and dividing spindle 9, camshaft workpiece 23 to be processed is connected between the thimble 21,22 of main shaft 4 and tailstock 3, power drive mechanism drives main shaft 4 and rotates, camshaft workpiece 23 and pattern 14 rotate simultaneously, the slide block 16 that drops on simultaneously on the pattern 14 drives unit head 17 upper tool pans 18 execution forming movements, moves the involute contour of milling camshaft by the profiling of cutterhead 18.Because main shaft 4 is 1/2 with the gearratio of dividing spindle 9, camshaft workpiece 23 just only changeed half-turn when pattern 14 rotated a circle, went out the involute contour of a side in its Surface Machining, at this moment, after pattern 14 is rotated further a circle, process the involute contour of camshaft workpiece 23 opposite sides.Adopt this method only need carry out one-time positioning, guaranteed the symmetry of the involute contour that processes, when increasing work efficiency, also reduced labour intensity.
