General clamp for abrasive flow polishing of complicated hole surface

Abstract

The invention discloses a general clamp for abrasive flow polishing of a complicated hole surface. The general clamp comprises a clamp body and one or more embedded modules; the clamp body is provided with uniformly distributed threaded holes in the peripheral direction; the clamp body comprises a lower pressing plate, a sleeve, an upper pressing plate and a sealing ring; the upper pressing plate and the sleeve are connected in a fastened manner; the lower pressing plate is connected with the sleeve; the upper pressing plate is provided with embedded module connecting holes and abrasive flow channel holes; the embedded modules are arranged in the clamp body; the embedded modules are detachably connected with the upper pressing plate in a fastened manner; the embedded modules compresses a non-polishing surface of a polished workpiece; the upper pressing plate is provided with the embedded module connecting holes uniformly distributed in the peripheral direction, and the embedded module connecting holes are used for connecting with different embedded modules; the abrasive flowing channel holes of the upper pressing plate are axially parallel to the polishing surface of the polished workpiece; the abrasive flow circulates in the abrasive flow channel holes in the part, which is not pressed and covered, of the upper pressing plate; when the surface of the polished workpiece is a curved surface, a columnar surface or a hole parallel to the direction of the abrasive flow, the embedded modules of corresponding shapes are replaced and recombined according to the appearance surface of the polished workpiece.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision machining, and relates to a general fixture for abrasive flow polishing with complex hole surfaces, in particular to a general fixture for complex hole surface abrasive flow polishing with built-in modules; it is especially suitable for various types of polished parts, A variety of hole, surface abrasive flow polishing, universal fixture. Background technique [0002] Abrasive Flow Machining (AFM) is a new technology for surface polishing and deburring of workpieces with a fluid viscoelastic material composed of a polymer carrier and abrasive. Extrusion honing or abrasive flow machining. In the process of abrasive flow polishing, the fixture is a very important part, which is related to the quality and efficiency of the process. Abrasive flow fixtures are used to hold the workpiece and guide the abrasive to the surface to be machined. In addition, the fixture also acts as a sealing flow...
