Boring cutter for processing engine oil injection nozzle

Abstract

The invention discloses a boring cutter for processing an engine oil injection nozzle. The boring cutter comprises a boring cutter body, wherein the boring cutter body comprises a cutter rod and a cutter head; a cooling channel is formed in the cutter rod; a through hole is formed on the surface of the cutter rod; and the cutter head and the end head of the cutter rod are integrally connected. According to the boring cutter for processing the oil injection nozzle of the engine, the anti-seismic performance in the processing process is effectively improved through the design of an eccentric structure and the redesign of a cutter tip part, meanwhile, the chip removal performance is better, the phenomenon of chip blockage is avoided, the use is more convenient, and the structural design is more reasonable; the design of the 40-degree acute angle included angle of the cutter tip part is matched with the 17-degree included angle at an extension part, so that the chip removal performance inthe reaming process is effectively enhanced; and the eccentric structure design of the cutter head and the cutter rod shape can effectively improve the overall structural strength of the boring cutter, and the anti-seismic performance is better.

Description

technical field [0001] The invention relates to the technical field of boring cutters, in particular to a boring cutter for processing engine fuel injection nozzles. Background technique [0002] Boring tool is a common tool in modern industrial production. Its main function is to expand the internal aperture of the workpiece. The engine fuel injector is a relatively basic component structure in the engine. The internal aperture of the fuel injector needs to be processed in actual processing. The boring tool is used, but the existing boring tool structure has the following disadvantages in actual use: [0003] During the cutting process, since the cutter head and the cutter head are uniform and symmetrical structures, the amount of vibration is relatively large during actual operation, which is prone to damage to the cutter head and the cutter rod, and due to the unreasonable design of the cutter head structure, resulting Crumb performance is poor.

Problems solved by technology

[0004] The object of the present invention is to provide a boring tool for processing engine fuel injection nozzles, to solve the above-mentioned background technology when cutting, because the cutter bar and the cutter head are uniform and symmetrical structures, so the amount of vibration is relatively large during actual operation. Large, prone to damage to the cutter head and the cutter bar, and due to the unreasonable design of the cutter head structure, resulting in poor chip removal performance
