A processing fixture and processing method for drilling holes on the surface of a conical bush

Abstract

The invention relates to a machining fixture and method for drilling a conoid bushing surface. The machining fixture comprises a fixture body and a handle, and one end of the fixture body is a fixed end; the other end of the fixture body is a machining end; the fixed end is fixedly connected to a machine tool workbench, and the machining end face is provided with a boss; the outer side of the machining end is provided with a reaming base, and one end of the handle is rotatably connected to the reaming base; the other end of the handle movably covers the end face of the boss; the machining method comprises the steps of preparing a workpiece and a machine tool separately, installing a cutter and the machining fixture on the machine tool, drilling holes, removing a finished conoid bushing andso forth; according to the technical scheme, the workpiece is located through the boss on the fixture body, and pressed by the handle, while the alignment of the workpiece is not required; the drilling procedures are simplified, and the operation is convenient; the workpiece is prevented from offsetting effectively, and the machining efficiency is improved; and lots of technological auxiliary time is saved, and the production efficiency and capacity are improved.

[0002] In recent years, the machinery and equipment manufacturing industry has developed rapidly. People have designed and manufactured a variety of machinery and equipment to facilitate people's production, life and other activities. Machinery and equipment are composed of parts of different shapes, sizes and functions. , a class of conical bushing parts is widely used in mechanical equipment. The outer surface of such conical bushing parts is generally processed by a lathe, but in some applications, it is often necessary to make the outer surface of the conical bushing parts Corresponding holes are processed on the surface. Since the outer surface of this type of conical bushing is arc-shaped, it is extremely difficult to clamp and position this type of workpiece. In the prior art, V-shaped blocks and corresponding clamping parts are generally used. However, the processing of the V-shaped block itself is extremely difficult, and it is difficult to ensure the processing accuracy, which affects the processing accuracy of the final cone-shaped bushing parts, especially when producing such cones in large quantities. For body-shaped bushing parts, due to the complicated clamping operation of the workpiece, the cumbersome process of workpiece alignment and size positioning, a lot of auxiliary process time is increased, and the production efficiency is low
