Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to an abrasive flow tooling. Background Technology

[0002] Abrasive Flow Machining (AFM) is an advanced surface treatment technology that uses semi-solid abrasive media flowing under pressure across the surface of a workpiece to achieve precision polishing, deburring, and chamfering. This technology utilizes viscoelastic fluid abrasives to perform micro-cutting on the workpiece under pressure, significantly improving surface quality. The core advantage of AFM lies in its ability to handle complex structures. It can efficiently machine deep holes, intersecting holes, internal cavities, and other areas that are difficult to reach with traditional processes, and is widely used in aerospace, automotive manufacturing, and medical device industries.

[0003] When performing abrasive flow machining, workpieces need to be fixed and restrained by tooling. However, when the feed hole of the tooling does not match the diameter of the workpiece's bore, the flow velocity of the abrasive entering the workpiece's inner bore and the pressure exerted on the bore wall are unstable, affecting the machining effect. Therefore, separate tooling is usually required to restrain workpieces with different bore diameters, which is costly and has poor applicability. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing abrasive flow tooling cannot process workpieces with different hole diameters and has low applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Furthermore, the limiting mechanism includes several lower slots, which are evenly opened on the top of the base around the axis of the base. Adjacent lower slots are coaxially arranged with the discharge hole. The bottom of the top cover is evenly opened with several upper slots along the axis. Adjacent upper slots are coaxially arranged with the feed hole, and opposite upper slots are coaxially arranged with the lower slots.

[0008] Furthermore, a lower limiting ring is detachably provided inside the lower slot, and an upper limiting ring is detachably provided inside the upper slot.

The lower inclined surface and the upper inclined surface are arranged in parallel, and a sealing groove is provided on both the lower inclined surface and the upper inclined surface.

[0011] Furthermore, a sealing ring is detachably provided between the pair of sealing grooves.

[0012] Furthermore, a handle is vertically fixedly connected to the top edge of the mounting ring.

[0013] The beneficial effects of this utility model are as follows:
