The specific embodiment:
Further specify the particular content of the present invention and the course of work thereof below in conjunction with the accompanying drawing illustrated embodiment.
Consult Fig. 1: the method that the present invention adopts annular knurl and assembling to carry out simultaneously designs.Knurling device 30 is loaded on the top of camshaft rigging position (being cam 25 putting positions).At first under the downward promotion of cylinder putter 18, chuck 23 clamps the mandrel 24 of camshaft, motor 3 can adopt AC servo motor, high-speed transmission ratio mechanism through speed-changing gear box 4 drives travelling gear 5 rotations, because travelling gear 5 is connected with the nut 7 of ball-screw 6, drives nut 7 and rotates, ball-screw 6 moves down fast, ball-screw 6 links to each other with slide block 12 by ring flange 11, and slide block 12 can slide up and down on line slideway 13, and slide block 12 lower ends are connected with mandrel 24 clamping and rotating systems.Because ball-screw 6 moves down fast, then mandrel 24 also moves down fast.When moving down into when desiring the annular knurl position, the piston 27 that ejects guiding oil cylinder 26 promotes to eject the lower end that guide post 28 withstands mandrel 24, when guaranteeing annular knurl mandrel 24 do not vibrate and the cam 25 of accurately packing in.Meanwhile, another motor 32 starts, and drives worm screw 31 rotations, drives rotations together such as oil cylinders 17 and fixture block 22, chuck 23 through worm gear 20, also rotation thereupon of mandrel 24, and mandrel annular knurl mechanism 30 carries out annular knurl processing.Owing to be that 120 ° of concentric processing of three cuttves can guarantee that annular knurl fast, evenly.After annular knurl finished, motor 3 was transformed into low speed ratio mechanism, and mandrel is pressed in the cam, and first cam is linked and packed and finishes.When carrying out being linked and packed of second cam, after annular knurl finishes, after adjusting angles, motor 32 can be pressed in the cam.The rest may be inferred, all finishes until being linked and packed.
Consult Fig. 4: speed-changing gear box is made up of high-speed transmission ratio mechanism and low speed ratio mechanism, main transmission clutch (40) on low speed main drive gear (39) and the high speed main drive gear (41) is housed on the final drive shaft (38), gearbox output gear (43), low speed output gear (36), high speed output gear (42) are housed on the output shaft (35) and be connected to low speed output gear (36) and high speed output gear (42) on output clutch (37).
The course of work of speed-changing gear box is: high-speed transmission ratio mechanism: motor 3 drives final drive shaft 38 and rotates, main transmission this moment clutch 40 connects, output clutch 37 separates, and final drive shaft 38 drives low-speed active gear 39, main transmission clutch 40, high speed main drive gear 41, high speed output gear 42, output shaft 35, gearbox output gear 43 rotate together, finish high-speed transmission ratio output (low speed output gear 36 idle running at this moment).
Low speed ratio mechanism: motor 3 drives final drive shaft 38 and rotates, main transmission this moment clutch 40 separates, output clutch 37 connects, final drive shaft 38 drive low speed main drive gears 39, low speed output gear 36, output clutch 37, high speed output gear 42, output shaft 35, gearbox output gear 43 rotate together, finish low speed ratio output (high speed driving gear 41 idle running at this moment).
In the clamping and rotating system, on the oil cylinder overcoat 14 at oil cylinder 17 turnover oilhole places, establish Baltimore groove, even can keep oil cylinder that hydraulic oil is freed in and out.Chuck 23 can be contained in the lower end of oil cylinder 17 cylinder bodies by fixture block 22.
Its course of work is: hydraulic oil is through hydraulic cylinder 17 upper oil hole oil-feeds, and push rod 18 promotes fixture block 23 downwards and clamps mandrel 24; Motor 32 rotations drive worm gear 20 through worm screw 31 and rotate.Because gear links to each other with oil cylinder, so drive oil cylinder and chuck, mandrel rotation.
Consult Fig. 5: the knurling tool 48 in the mandrel annular knurl mechanism 30 can adopt 3 and be distributed on the inwall of described annular knurl rotating disk 45, and knurling tool 48 is contained on the guide rail 47, and the runner 46 on the knurling tool 48 contacts with annular knurl rotating disk 45 inwalls that are round involute shape.
The course of work of mandrel annular knurl mechanism 30 is: in the time will carrying out annular knurl to mandrel 24, annular knurl hydraulic cylinder 44 is according to arrow direction, annular knurl rotating disk 45 rotates counterclockwise, runner 46 contacts with annular knurl rotating disk 45 inwalls, because inwall is the involute shape of circle, along with the rotation of annular knurl rotating disk, promotion knurling tool 48 to axe movement, begins annular knurl processing along guide rail 47 when arriving the annular knurl position.
