According to the invention, a crankshaft raw material to be processed is clamped between the other eccentric shaft adjusting clamp groups 3 by moving one of the eccentric shaft adjusting clamp groups 3, then the rotary driving host machine 2 is started to drive and rotate, then the turning tool driving slide rail 4 is started to drive the lower end processing lathe tool rest 8, then the processing lathe tool rest 8 is driven to move downwards, the lower end processing lathe tool 9 turns the main shaft of the crankshaft raw material wire by wire and buckle by buckle, and then the eccentric shaft adjusting clamp groups 3 are used for adjusting, and the rotating axis is adjusted to the position of each connecting rod shaft one by one;
Wherein, the rotary driving host 2 drives the rotary driving shaft 307 to rotate, and the rotary driving shaft 307 passes through the clamp back seat 302 to drive the rotary shaft turntable 303 to rotate, so as to drive the front end crankshaft fixing fluted disc 309 to rotate, wherein the crankshaft top shaft boss 310 can prop against a positioning center hole drilled on the side surface of the crankshaft, and the three-jaw fixing clamp 311 can clamp the crankshaft raw material;
After the main shaft on the crankshaft is turned, the rotating shaft turntable 303 is rotated, the rotating shaft turntable positioning groove 316 is opposite to one side of the turntable limiting disc 3138, then the first electric sliding rail 3131 is started, the turntable limiting disc push rod 3132 at the front end is driven to move towards the rotating shaft turntable 303, so that the turntable limiting disc 3138 is clamped in the rotating shaft turntable positioning groove 316 and prevented from rotating in the adjusting process, then the second electric sliding rail 3133 is started, the eccentric shaft adjusting shaft sliding block 3134 is used for butting one side of the screw rod driving rotating shaft 3139 with one end of the locking base driving screw rod 305, the driving rotating shaft motor 31312 is started, the screw rod driving rotating shaft 3139 is used for driving the locking base driving screw rod 305 to rotate, and accordingly a screw rod sleeve integrated with the rear end of the locking base assembly shell 3061 can be driven to move, and the distance between the connecting rod shaft and the main shaft is adjusted;
Then, by starting the third electric sliding rail 3135 and driving the toothed disc motor mounting slide block 3136, the locking driving hexagonal head 31310 is inserted into the locking nut 3065, and simultaneously the angle adjusting toothed disc 315 is meshed with the side surface of the crankshaft fixing toothed disc 309, firstly starting the hexagonal head driving motor 31313 and driving the locking driving hexagonal head 31310 to rotate, so that the locking nut 3065 can be driven to rotate, and the second bevel gear 30614 at the inner end can be linked to rotate, so as to engage the first bevel gear 30610, and then the inner supporting locking screw rod 3069 at the inner front end drives the inner supporting locking screw sleeve 3061 to linearly move, so that the sliding locking inner supporting slide block 3067 can be pushed to linearly slide inwards, and the state that the sliding locking inner supporting slide block 3067 is in abutting contact with the crankshaft toothed disc coaxial base 3063 can be released, and because the crankshaft toothed disc coaxial base 3063 is connected with the crankshaft fixing toothed disc 309, at the moment, the adjusting toothed disc motor 31311 is started again, and the angle adjusting toothed disc 315 is meshed with the crankshaft fixing toothed disc 309 to rotate, so that the deflection angle between the crankshaft fixing toothed disc intervals can be adjusted, and then the crankshaft fixing toothed disc 309 can be locked;
according to the scheme, the crankshaft connecting rod with multiple connecting rod shafts and multiple angle distribution of the connecting rod shafts can be processed, compared with the prior art, the crankshaft connecting rod is more convenient to process, and all the adjusting parts are in independent fit contact, so that the situation that meshing and penetration are not carried out during interval adjustment is avoided.
