Fixing mechanism for crankshaft machining

Technical Field

The utility model relates to the technical field of crankshaft machining, in particular to a fixing mechanism for crankshaft machining.

Background

As is well known, a crankshaft is the most important component in an engine, and can bear the force transmitted by a connecting rod, convert the force into torque, output the torque through the crankshaft and drive other accessories on the engine to work, and the crankshaft is subjected to the combined action of the centrifugal force of rotating mass, the gas inertia force which changes periodically and the reciprocating inertia force, so that the crankshaft bears the action of bending and torsion load, therefore, the crankshaft is required to have enough strength and rigidity, the journal surface needs to be wear-resistant, work uniformly and balance well, and people usually use corresponding fixing mechanisms to fix the crankshaft in the process of processing the crankshaft.

Through searching, the utility model patent with the Chinese patent number of CN202023183461.7 discloses a fixing mechanism for crankshaft machining, which comprises a fixing seat, wherein the upper surface of the fixing seat is fixedly connected with a fixing table, grooves are symmetrically formed in the fixing seat, mounting grooves are respectively formed in the outer walls of two opposite sides of the two grooves, sliding grooves are formed in the lower surface of the grooves, a bearing is fixedly connected in the mounting grooves, a screw rod is rotatably connected to the inner wall of the bearing, and a turntable is fixedly connected to one end, far away from the bearing, of the screw rod. When the screw sleeve is used, the turntables on the outer walls of the two sides of the fixed seat are rotated at first, the turntables drive the screw rod to rotate on the bearing, the screw rod drives the screw sleeve to move, and the connecting rod is driven by the screw sleeve to drive the pressing plate to move due to the fact that the sliding block is fixedly connected to the bottom of the screw sleeve and is in sliding connection with the sliding groove. The bottom of the pressing plate and the upper surface of the fixed table are on the same horizontal line, the other pressing plate can move in the same way, and the two pressing plates fix the outer walls of the two sides of the crankshaft, so that the two pressing plates cannot move on the horizontal plane; at the moment, the pull plate is pulled again, the pull plate drives the push rod to move upwards, meanwhile, the pull plate drives the spring to deform, the pressing block is located on the upper surface of the crankshaft, at the moment, the pull plate is loosened again, the pull plate pushes the push rod to move downwards under the action of the spring, the push rod pushes the pressing block to move downwards, and the pressing block fixes the upper surface of the crankshaft.
