Novel jet machining and detection integrated precision equipment

Abstract

The invention discloses novel jet machining and detection integrated precision equipment. The equipment comprises a workbench used for loading a workpiece, a measuring mechanism used for measuring the workpiece, a jet mechanism used for conducting jet machining on the workpiece according to a detection result and a movement mechanism, and the workbench is movably arranged on the movement mechanism. The measuring mechanism and the jet mechanism are arranged at the two ends of the movement mechanism respectively, the movement mechanism drives the workbench to move back and forth to the position below the measuring mechanism and the jet mechanism in a reciprocating mode, and measurement and jet machining are conducted on the workpiece respectively. A detection device and a machining device are integrated, after being measured by a laser interferometer, the workpiece can be directly moved to the position below the jet device to be machined, integrated manufacturing and machining are achieved, and errors caused by multiple times of clamping are reduced.

Description

technical field [0001] The invention relates to a processing device, in particular to a device for performing abrasive jet finishing on the surface of a workpiece. Background technique [0002] Abrasive water jet polishing technology is to use the polishing liquid mixed with fine abrasive particles sprayed at high speed from the nozzle to act on the surface of the workpiece, and achieve the purpose of grinding and removing materials through the high-speed collision and shearing of abrasives. , Angle and injection time and other process parameters to modify the polishing process of the surface roughness of the workpiece. [0003] In the current process flow, before spraying the workpiece, it is necessary to use the detection device to measure the surface of the workpiece to determine the processing position. After the detection result is obtained, the workpiece is polished by the spraying device. Install the workpiece under the detection device through the fixture, disassemb...

Problems solved by technology

[0003] In the current process flow, before spraying the workpiece, it is necessary to use the detection device to measure the surface of the workpiece to determine the processing position. After the detection result is obtained, the workpiece is polished by the spraying device. Install the workpiece under the detection device through the fixture, disassemble the workpiece after the detection is completed, and install it again under the spray device for polishing. Repeated disassembly and assembly of the workpiece in this way will not only consume time and labor, reduce work efficiency, but also may It will bring errors to the measurement and processing, and the measurement accuracy of the existing detection methods is often not high enough to perform high-precision control to ensure the polishing quality. Basically, it cannot meet the requirements of finishing, especially the nanometer level. Precision
