Problems solved by technology
On the surface, this method is simple and easy to operate, but the actual effect is unsatisfactory; because the rotary file is used for deburring, and the observation of the oil passage hole is not intuitive, the effect of manually using the rotary file to remove the burr is very unreliable ;Use a rotary file to remove the burrs in the oil passage holes. Since the working principle of the rotary file is similar to the cutting principle, in practice, the intersection positions of the oil passage holes that are prone to burrs appear alternately, and the burrs need to be removed repeatedly, which not only reduces the It reduces the production efficiency, and it is easy to fatigue after a long time of manual work, which is not conducive to the stable guarantee of deburring quality

Embodiment Construction
[0020] The present invention will be specifically described below in conjunction with the accompanying drawings. As shown in the figure, in the deburring processing method of the present invention, the cutter 3 that penetrates into the oil passage hole 1 is close to the burr and the burr is removed; the cutting edge 2 back of the cutter 3 is provided with a nozzle 4. The nozzle 4 is in communication with the pressure liquid source, and the reaction force of the liquid 6 ejected from the nozzle to the pressure generated in the inner cavity of the oil passage hole makes the cutter 3 stick to the burr; the cutter is composed of an elastic cutter rod and a power header connection. The deburring tool of the present invention comprises a cutting edge 2, the back of the cutting edge 2 is provided with a spout 4, and the spout 4 communicates with the pressure liquid source through the central hole 5 of the elastic knife rod 8, and the elastic knife rod is connected with the knife handl...

The invention discloses a crankshaft oil channel hole burr removing machining method and a tool. The back face of a cutting edge of the tool is provided with a spraying opening, the spraying opening communicates with a pressure liquid source, and counter-acting force of pressure generated by liquid sprayed out of the spraying opening to an inner cavity of an oil channel hole enables the tool to beattached to burr. The tool is connected with a power head through an elastic tool rod. The burr removing tool comprises the cutting edge. The back of the cutting edge is provided with the spraying opening, the spraying opening communicates with the pressure liquid source through a center hole of the elastic tool rod, the elastic tool rod is connected with a tool handle, and the tool handle is fixed to the power head. The crankshaft oil channel hole burr removing mechanism method and the tool have the advantages that the burr of the oil channel hole can be effectively removed, the oil channelhole burr removing stability is improved, repeated reworking is avoided, and the machining efficiency is improved.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a method and tool for removing burrs. Background technique [0002] The crankshaft is one of the five most important core components in the engine, and its quality is crucial to the performance and service life of the engine. Everyone knows that in addition to the requirements for dimensional accuracy, roughness, and surface hardness, the crankshaft also has an important quality index: the cleanliness of the crankshaft. The cleanliness of the crankshaft is directly related to the smoothness of the oil passage of the engine and the lubrication and wear of the kinematic pair. If the cleanliness of the crankshaft is not good, the parts will be lost and the performance will be reduced, and the engine will be scratched and held, and even the engine will be scrapped. [0003] The burr at the intersection position in the crankshaft oil passage hole is a key indicator affecting the cleanliness o...
