Description

Technical Field

[0001] This utility model relates to the field of steel plate manufacturing equipment, and in particular to an automatic gripping mechanism for processing engine flywheels. Background Technology

[0002] In the current process of manufacturing engine flywheels, such as drilling, the flywheels from the previous process are stacked in a transition hopper by hand. After one process is completed, the flywheel needs to be moved to the next process location for further processing. This process is inefficient, and the manual handling in between is troublesome.

[0003] Therefore, some existing methods involve setting up a conveyor mechanism between two process equipment to transport the flywheel processed in the previous process to the next process. However, the existing conveyor mechanism cannot accurately position the flywheel, so when it is transported to the equipment of the subsequent process, the gripping mechanism on that equipment cannot accurately grip the flywheel, affecting its automated continuous processing.

[0026] The implementation principle of an automatic gripping mechanism for engine flywheel processing according to an embodiment of this application is as follows: During operation, the operator places the flywheel on the outside of the positioning seat 5, precisely positioning it on the turntable 4. Then, the servo motor 67 drives the drive pulley 63 to rotate, which in turn drives the driven pulley 64, the rotating rod 62, and the turntable 4 to rotate via the belt 65, rotating the flywheel from the previous processing step to the gripping end of the transfer component 3 and pausing it. At the same time, during the rotation of the turntable 4, the push cylinder 73 pushes the positioning block 72 to rise, so that the positioning block 72 can abut against the fixed block 71, preventing the turntable 4 from rotating excessively and ensuring that the flywheel can be precisely stopped directly below the gripping end of the transfer component 3. Afterward, the lifting cylinder 32 lowers the finger cylinder 34, which drives the first clamping plate 36 and the second clamping plate 37 to approach and clamp the sides of the flywheel. Then, the lifting cylinder 32 rises, and the servo slide guide module 31 transfers the flywheel to the next processing step.
