When the clamping device works specifically, after the clamping support 4a enters an inner cavity of the speed reducer, the clamping slip ring 4c is pulled by the clamping cylinder 4e to slide downwards along the inner wall of the clamping slip cylinder 4b, the clamping connecting rod 4d is further driven to move downwards synchronously, because the middle part of the rotating frame 4e is fixedly arranged on the clamping support 4a in a rotating fit manner, the rotating frame 4e starts to rotate per se in the process of pushing the clamping connecting rod 4d downwards, the lower end of the rotating frame 4e rotates outwards, the upper end of the rotating frame 4e rotates inwards, the supporting slide block 4k is further driven by the limiting slide block 4h to slide towards one end of the shell of the speed reducer along the supporting slide way 4j, at the moment, the supporting spring 4m is in a stretching state, and the rotating path distance caused by the angle change of the sliding fit between the limiting slide groove 4f and the limiting slide block 4h can adapt to the change during the rotation, the limiting spring 4g accessible spring effect that sets up promotes limiting slide 4h and supports all the time and lean on the inner wall of spacing spout 4f, avoids during operation limiting slide 4h to take place to rock, sets up the inclined plane on supporting slide 4k and can make supporting slide 4k better insert the clearance between speed reducer casing lower extreme and the forming die.

The upper end of the rotating frame 4e drives the clamping rack 4n2 to slide inwards along the clamping sliding groove 4n1 through hinge transmission while rotating, and further drives the clamping gear 4n3 to rotate through meshing transmission, because the clamping gear 4n3 is fixedly arranged on the clamping bracket 4a through rotating matching, the clamping gear 4n3 further drives the positioning slide seat 4n6 to slide outwards along the positioning rod 4n4 through meshing transmission between the clamping gear 4n3 and the meshing teeth 4n7, at the moment, the positioning spring 4n5 is in a stretching state, the positioning slide seat 4n6 further drives the connecting shaft 4n8 to move while moving, the connecting shaft 4n8 further drives the positioning side plate 4n10 to rotate along the connecting rod 4n9 through sliding fit between the connecting shaft 4n8 and the positioning sliding chute 4n11 until the side wall of the positioning side plate 4n10 is attached to the inner wall of the speed reducer shell.

Then, the vibration motor 3n is controlled to rotate, the vibration rotary disc 3m is further driven to rotate, the vibration rotary disc 3m continuously drives the clamping support 4a to perform reciprocating lifting motion through the abutting fit between the arranged vibration lug 3p and the circular lug while rotating, the arranged vibration slide rod 3h can limit the moving path of the clamping support 4a, the arranged vibration spring 3j can pull the circular lug to always abut against the side wall of the vibration rotary disc 3m through the elastic action, the reciprocating vibration of the speed reducer shell is further driven through the reciprocating vibration of the clamping support 4a, so that the speed reducer shell is better separated from a forming die, then, the lifting sliding plate 3d is further pushed to move upwards through the lifting cylinder 3c, the shifting Contraband-shaped frame 3g is pushed to move outwards through the shifting cylinder 3e, the speed reducer shell is taken away from the outer side of the forming die, then the clamping sliding ring 4c is pushed to slide towards the upper end through the clamping cylinder 4e, the clamping operation on the speed reducer shell is further removed, the speed reducer shell is collected and cooled through manpower and placed, after the cooling is completed, the speed reducer shell is further subjected to fine machining operation through the manpower, and a finished speed reducer shell product is obtained.
