Description

Technical Field

[0001] The utility model relates to the technical field of automobile engine cylinder body processing and production, in particular to a cylinder body grabbing device with locking and limiting function. Background Art

[0002] In the production of engine cylinders, using robots to carry out the handling of engine cylinders is a key technology to achieve production automation. However, the gripping device on the robot is an even more important part. The existing clamping method is to flatten cylindrical pins, locate the holes at the straight ends of the pins, and expand them to create friction between the workpiece and the pin shaft that is greater than gravity, thereby achieving gripping. Due to the complex structure of the engine cylinder itself and its heavy weight, the cast iron cylinder weighs more than 100kg, and it is difficult for friction to overcome gravity. In addition, there are relatively large safety risks. When the robot grips and clamps the engine cylinder, a very high clamping force is required. Utility Model Content
