Description

Technical Field

[0001] The utility model relates to the technical field of connecting rod processing, in particular to a turning device used for connecting rod processing. Background Art

[0002] It connects the piston and crankshaft, transmits the force applied to the piston to the crankshaft, and converts the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod group consists of a connecting rod body, a connecting rod big end cover, a connecting rod small end bushing, a connecting rod big end bearing and a connecting rod bolt (or screw). The connecting rod group is subjected to the gas force transmitted from the piston pin, its own swing and the reciprocating inertia force of the piston group. The magnitude and direction of these forces change periodically. When processing the connecting rod, it is usually necessary to use a flipping device to flip the connecting rod.

[0003] When using a flipping device to flip the connecting rod, the connecting rod is usually driven to rotate. For example, application number: CN202023302456.3 discloses a flipping device for crankshaft connecting rod processing. The flipping device used in the above utility model can realize the flipping of the connecting rod, but during the production and processing of the connecting rod, it is usually necessary to adjust the height and angle of the connecting rod. The above utility model does not have the function of adjusting the height and angle of the flipping device, and thus cannot adjust the height and angle of the connecting rod. This results in poor flexibility of the flipping device, which is not conducive to the production and processing of the connecting rod. Utility Model Content
