Embodiment Construction
[0025] Embodiments: In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that all the drawings of the present invention are in simplified form and use inaccurate scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.
[0026] The invention provides a crankshaft and crank pin processing tool, such as Figure 1~2 Shown, including: serrated knife (not shown) and ultra-fine grain carbide broad edge knife. The ultra-fine-grain hard alloy wide-edged knife includes: a knife holder 10 and a blade 20 installed on the knife holder 10, and the blade 20 is made of tungsten-cobalt ultrafine grain cemented carbide. Specifically, the main journal of the crankshaft 30 is roughly machined with a...

Abstract
The invention discloses a crankshaft and a crank pin machining tool. The machining tool comprises a sawtooth cutter and an ultra-fine grain cemented carbide broad-blade cutter, wherein the ultra-fine grain cemented carbide broad-blade cutter comprises a cutter clamp and a blade mounted on the cutter clamp, and the blade is made of tungsten-cobalt ultramicron cemented carbide. Compared with the prior art, the number of used cemented carbide broad-blade cutters is reduced, the production cycle is shortened, production efficiency is improved, and production cost is further lowered; the broad-blade cutter does not need to be clamped or replaced, and the problem that cutter setting of a machining tool in the prior art is difficult is solved. In addition, the adopted ultra-fine grain cemented carbide broad-blade cutter has the advantages of being high in hardness, good in abrasion performance, long in service life and good in finished surface roughness.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a tool for processing crankshaft main journals and crank pins. Background technique [0002] The crankshaft is the main rotating mechanism of the engine. It is responsible for converting the up and down reciprocating motion of the piston into its own circular motion. Therefore, the processing conditions of the crankshaft are relatively strict. The main journal of the crankshaft and the outer circle of the crank pin can only be processed by turning on a lathe, and cannot be ground by a grinder. The processing tools currently used are arranged in the order of processing the main journal of the crankshaft and the crank pin, which are: serrated cutter (clamping cutter), carbide wide-edged cutter and high-speed alloy wide-edged cutter. Among them, the zigzag knife performs rough machining on the main journal, leaving a margin of 0.15~0.20mm. Then, use a hard alloy wide-edged kni...
