Abstract

The invention provides a drilling device special for a support part, and belongs to the technical field of machining. The drilling device comprises a base, a positioning block, a supporting plate, a drilling plate, a drilling sleeve, a pressing sliding block, a support, an adjusting bolt and a J-shaped supporting block. When the drilling device is used for drilling a bracket part on a common drilling machine, the quick positioning operation of the part can be realized, and the positioning surface is a finish machining surface, so that the positioning precision is high; according to the device, positioning can be rapidly achieved through the finish machining surface of a part, clamping is rapidly achieved through the pressing sliding block, and the device is simple and convenient to use; meanwhile, the drilling device is made of common materials, and each part is simple in structure, convenient to machine, low in manufacturing cost, low in maintenance cost and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of machining, and relates to a special drilling device for bracket parts. Background technique [0002] The bracket part is an important part in the aircraft hydraulic system, which plays an important role in connecting the finished product. The bracket part has a complex shape, a large number of space dimensions, and various features on the part are irregularly distributed. This type of part is generally a semi-machined part. , First, the blank is obtained by casting or forging, and the basic shape of the part is obtained, and then part of the structure is finished according to the application of the part. In addition, for some bracket parts produced by casting, even if the machining can be completed on a milling machine or a lathe, it is difficult to select and clamp the positioning surface, and even cause the product to be out of tolerance and scrapped. [0003] The invention relates to a bracket part, t...
