Description

Technical Field

[0001] The utility model relates to the technical field of fire trucks, in particular to a single-machine double-station abrasive flow deburring device. Background Art

[0002] Abrasive flow deburring refers to an extrusion method in which the abrasive is fluid and the particles continuously grind the workpiece surface to complete the polishing and deburring process. It is suitable for polishing irregular surfaces that are not easy to clean with conventional tools.

[0003] At present, most of the common abrasive flow grinding devices on the market are single-station abrasive flow equipment. The equipment mainly includes a power part for extruding abrasives. The power part is connected to a conveying pipeline, and the pipeline is connected to a discharge flange that docks with the workpiece. The abrasive is pressed into the workpiece through the flange discharge, and the top of the workpiece is pressed by an auxiliary oil cylinder. The abrasive continuously passes through the inside of the workpiece for grinding. Each grinding process of the single-station equipment requires installation and disassembly of the workpiece at a single station. Because most of the workpieces need to be assisted by designated tooling for installation, this process is relatively cumbersome. When disassembling and installing the workpiece, the equipment is in a stopped state. When polishing a large number of workpieces, it affects work efficiency. Different tooling and fixtures are also required to clamp the workpieces for the same type of elbow pipe fittings with different sizes. When polishing the same type of elbow pipe fittings with different sizes, changing tooling is time-consuming and cumbersome.

[0004] The patent technology with application number 201721683639.X in the prior art discloses a unidirectional and bidirectional dual-station combined abrasive fluid polishing machine. Although the technology discloses a dual-station abrasive flow device, the technical solution it adopts is that the dual stations use different abrasive flow methods to polish the workpiece. One station is a unidirectional abrasive flow, and one station is a bidirectional abrasive flow. The two stations are not the same, and the workpieces and polishing methods they target are also different. In essence, they are two different devices spliced ​​together by a frame. When replacing the workpiece at the station, it is inevitable to wait for the workpiece to be replaced before processing, which is a waste of time.

[0005] Therefore, the problem that the inventor wants to solve is to design a double-station polishing device to improve work efficiency, which is suitable for polishing elbows of the same type but different sizes and has a wide range of applicability. Utility Model Content
