Description

Technical Field

[0001] The utility model relates to the field of drilling devices, in particular to a drilling device for a flange plate used in a hydraulic cylinder. Background Art

[0002] The drilling device for hydraulic cylinder flanges is a device used to drill holes on hydraulic cylinder flanges. Hydraulic cylinders usually have flanges that are used to connect the hydraulic cylinders with other equipment or structures. During the processing of hydraulic cylinder flanges, it is often necessary to drill holes on the flanges of the hydraulic cylinders in order to install accessories or connect other components.

[0003] Application number: CN202223061130.5, discloses a flange drilling device, which uses two fixed ends to fix and clamp the flange. At the same time, under the action of a pressure member, the flange is prevented from displacement or tilting, effectively improving the processing accuracy of the flange. At the same time, the second fixed end can be adjusted in position by a vertical rod to adapt to the drilling operation of flanges of different sizes. At the same time, under the action of a second motor, the flange can be driven to rotate, making processing more convenient.

[0004] However, the number of holes required to be drilled in the hydraulic cylinder flange is often large. Compared with the flange drilling device in the patent, it is difficult to drill multiple holes on a hydraulic cylinder flange at the same time. In addition, the diameter of the flange will also vary depending on the specifications of the hydraulic cylinder. Compared with the drilling device in the patent, it is also difficult to flexibly adjust the drilling position according to the different flange diameters. For this reason, we propose a drilling device for a hydraulic cylinder flange. Utility Model Content
