Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder processing devices, in particular to a clamping device for oil cylinder processing. Background Art

[0002] The oil cylinder is one of the most important components of construction machinery. As the main component of the oil cylinder product, the processing quality of the cylinder barrel directly affects the use reliability and service life of the whole product. The processing requirements of the cylinder barrel are high. During the processing of the cylinder barrel of the oil cylinder, its surface needs to be polished, and a clamping device is usually required to fix the oil cylinder during the processing of the oil cylinder.

[0003] In the prior art, the patent with the application number CN202223032645.2 proposed a hydraulic cylinder positioning tooling. It starts the servo motor to make the second gear fixedly connected to the output end of the servo motor rotate, makes the second gear drive the meshing-connected first gear to rotate, and then makes the multiple teeth fixedly connected to the outside of the first gear drive the steering gear outside the threaded barrel to rotate. When the steering gear rotates, since the threaded barrel is threadedly connected to the threaded rod and the threaded rod is fixedly connected to the clamping plate, under the limitation of the first telescopic rod, the threaded rod pushes the clamping plate to move, so that the clamping plate clamps and fixes the cylinder block, and different-sized cylinder blocks can be quickly fixed. However, the patent with the application number CN202223032645.2 will block a part of the cylinder barrel of the oil cylinder when clamping the oil cylinder, and the clamping position is fixed. It is impossible to select the clamping position according to the processing position of the oil cylinder barrel, resulting in the unprocessed area at the clamped part of the oil cylinder. The oil cylinder needs to be removed and fixed again, resulting in a complicated oil cylinder processing process and low processing efficiency; moreover, the size of the oil cylinder that can be processed by the existing clamping device for oil cylinder processing is fixed, and it is difficult to clamp and process the cylinder barrels of oil cylinders with different diameters.
