Rapid assembling and disassembling combination fixture for removing burrs on inner walls of slender rods through ultrasonic compositing of abrasive flows

Abstract

A rapid assembling and disassembling combination fixture for removing burrs on the inner walls of slender rods through ultrasonic compositing of abrasive flows is characterized by comprising a fixture upper main body (5) and a fixture lower main body (6); the fixture lower main body (6) is sleeved with the upper part and the lower part of the fixture upper main body (5); a nut (4) is mounted on a thread section of the fixture lower main body (6) in a screwed mode and located between the upper part and the lower part of the fixture upper main body (5); an annular abrasive cavity (13) is formed in the lower portion of the fixture upper main body (5); feeding of the annular abrasive cavity is conducted through feeding inlets (14); a circle of multiple discharging connectors (15) communicating with the annular abrasive cavity (13) are arranged on the lower portion of the fixture upper main body (5); an elastic clamping hoop (3) is installed on a disk body (16) where the lower end of the fixture lower main body (6) penetrating through the fixture upper main body (5); and the slender rods to be machined penetrate through installing groove holes (12) between the disk body (16) and the elastic clamping hoop (3) and then are inserted into the feeding inlets (14). Clamping is convenient, efficiency is high, and the inner walls of more than eighteen slender rods can be machined at a time.

Description

technical field [0001] The invention relates to a fixture for mechanical processing, in particular to a fixture for machining the inner wall of a slender rod with abrasive flow, in particular to a quick-installation and quick-disassembly combined fixture for ultrasonic composite removal of burrs on the inner wall of a slender rod by abrasive flow . Background technique [0002] The surface finishing of the workpiece has always been the focus of researchers. The surface quality of the workpiece determines the performance and reliability of the workpiece. Especially in aerospace, national defense and military, etc., its importance is particularly prominent, such as the deburring of valves and spools of parts that play an important role in aerospace, as well as metal thin tubes and cross holes in medical equipment. The deburring process of the inner wall of the slender rod also needs to be solved urgently. [0003] Most of the original slender rod fixtures are single fixtures...

Problems solved by technology

[0004] The purpose of the present invention is to design a kind of abrasive flow ultrasonic compounding machine that can clamp at least 18 rods at a time, aiming at the problem that most of the existing slender rods are single-clamped during abrasive processing on the inner wall, with low efficiency and inconvenient clamping.
