Water jet deburring and surface finishing apparatus

Abstract

The invention relates to a deburring apparatus, specifically to a water jet deburring and surface finishing apparatus. The water jet deburring and surface finishing apparatus comprises a collecting box arranged in a protective cover; the side surface of the collecting box is provided with a filter and an oil-water separator; the top surface of the collecting box is fixedly provided with a machining center execution mechanism; a central water outlet main shaft device is fixed on the top crossbeam of the machining center execution mechanism; a high pressure water generating device with a surface-mounted pressure regulator is connected with a rotary joint at the upper end of the central water outlet main shaft device through a high pressure pipeline; the lower end of the central water outlet main shaft device is connected with a high pressure water jet nozzle; and the top of the protective cover is provided with a mist arrester, and the mist arresting port of the mist arrester is arranged to be correspond to a cleaning station of the high pressure water jet nozzle. The water jet deburring and surface finishing apparatus can highly efficiently and reliably remove burrs of machined parts and carries out cleaning and surface finishing on the parts at the same time.

Description

Technical field [0001] The invention relates to a deburring device, in particular to a water jet deburring surface finishing equipment. Background technique [0002] During the initial processing and forming process of mechanical parts, burrs will appear on the surface, especially some shell parts, valve parts and hole parts. From the point of view of processing technology, there are many processing procedures, many holes, and a long cycle. , The position of the burr after processing is special, especially the burr at each cross hole, which is invisible, intangible, and difficult to remove. A shell part often has hundreds or even thousands of size requirements and a large number of diameter, depth and accuracy requirements. For different holes, small holes with a depth-to-diameter ratio greater than 10 account for more than 30% of the total. If the removal is not clean, it will become a dangerous source of process pollution, affecting the reliability and life of parts, component...

AI Technical Summary

Problems solved by technology

The abrasive flow method is suitable for removing burrs of simple shells and single inner hole parts. For complex shell parts, the flow guide problem of abrasive flow in the criss-cross hole system is not easy to solve, and it cannot handle the burrs of such parts well. The problem of removing burrs in various holes requires customizing corresponding complex molds, and the removal efficiency is low

The electrochemical deburring method is limited by the size of the electrode, and it is only suitable for processing diameters larger than the ultrasonic deburring method. The ultrasonic grinding head is used for vibration grinding and deburring. The processing efficiency is low and it is difficult to control the processing accuracy.

Single brush deburring device, after processing, the workpiece needs to be cleaned in the next step, which is inefficient

Chinese patent 200910248542.X uses water jet technology to remove burrs in tiny holes, and uses a single nozzle 350Mpa ultra-high pressure water jet cutting machine for deburring. Not only is the efficiency low, but also, due to the use of ultra-high pressure water jets, Easy to damage the workpiece

[0003] For deep hole burrs, it is basically still in the stage of manual processing of burrs, that is: with the help of cold light source and endoscope observation, use autonomous hand tools (special-shaped scrapers, files, special grinding tools, etc.) Burrs, high labor intensity, long cycle, high cost, low efficiency, difficult to ensure consistent product quality, not conducive to the assembly line operation in batch production and the realization of the flexibility of product manufacturing, undue scratches are prone to occur during the deburring process , leading to rework or even scrapping, which increases the manufacturing cost of the part
