Abstract

PURPOSE:To omit the treatment process for cylinder bore and suppress the cost by machining the bore of cylinder so that it becomes larger gradually from the piston upper limit to lower limit, and by grinding the bore with piston motions. CONSTITUTION:The bore 13 of the cylinder chamber 8 of cylinder body 2 is so machined that its portion above the upper limit of piston 9 is plumb and the portion corresponding from the upper limit to the lower limit is tapered with a certain angle. Piston 9 is installed in the cylinder body 2 and actuated to grind the bore 13 of the cylinder chamber 8. This will eliminate honing and cylindrical grinding of the pore of cylinder to allow omission of the treatment process.

However, as mentioned above, polishing the inner surface of the cylinder by cylindrical polishing or honing is very time-consuming and requires a certain amount of equipment, which is not desirable in terms of time and man-hours and work efficiency. There was also the problem of high costs. In addition, in order to separately finish and assemble the piston and cylinder parts, the cylinders, etc. must be highly accurate in roundness, especially in small toy engines. It was extremely difficult.

Therefore, the polishing process can be performed efficiently and work efficiency is high.
There was a need for a cylinder inner surface treatment that was low cost and did not require high roundness.

[Means for Solving Problems] The present invention has been made to solve the above-mentioned conventional problems, and as a means for solving the problems, the method for treating the inner surface of a toy engine cylinder according to the present invention is such that the inner diameter of the cylinder is From the upper limit position to the lower limit position, the cutting process is performed successively,
The piston is assembled into the cylinder while the inner surface of the cylinder is in a cutting state, and then the piston is operated to polish the inner surface of the cylinder.

The inner surface 13 of the cylinder chamber 8 is formed vertically at the upper limit position of the piston 9 and tapered at a predetermined angle of 0 from the upper limit position to the lower limit position, and this tapered portion reduces the side pressure applied to the inner surface 13. I'm trying to do what I can.

First, the inner surface 13 of the cylinder chamber 8 is cut using a lathe. In this case, the piston 9 is cut so that the inner diameter is the same at the upper limit position, and the inner diameter is sequentially increased from the upper limit position to the lower limit position at a predetermined angle θ. High accuracy such as roundness is not required here.

Next, the piston 9 is assembled into the cylinder body 2 while the inner surface 13 of the cylinder chamber 8 is in the cutting state. In this case, the inner surface 13 of the cylinder chamber 8 remains cut by the lathe described above, and is not polished by honing or cylindrical polishing. Use what you already have. At this stage, the piston 9 is of course connected to the crank 7, and the cylinder head 3 is also attached, and the piston 9 is in a substantially completed state except for the internal polishing process.

Then, in the above state, the piston 9 is operated to polish the inner surface 13 of the cylinder chamber 8. In this case, the number of processes can be omitted by utilizing the engine test run process. In addition, the cylinder body 2 is generally made of aluminum, cast iron, brass, etc. with a hard chrome plated inner surface, and the piston 9 is made of steel or nickel, so the inner surface 13 of the cylinder chamber 8 is reliably worn and polished. The shape and dimensions of the piston 9 are adjusted. Therefore, the inner surface can be polished to a glossy finish without requiring equipment for honing or cylindrical polishing, and without requiring any special man-hours.

[Effects of the Invention] As explained above, in the method for treating the inner surface of a toy engine cylinder according to the present invention, the inner diameter of the cylinder is machined to gradually increase in size from the piston upper limit position to the lower limit position, and the cylinder is left in this cutting state. Since a piston is installed inside the cylinder and the inner surface of the cylinder is then polished by the operation of the piston, internal surface treatments such as honing and cylindrical polishing are no longer required, and the polishing process can be performed efficiently by omitting the processing steps for that purpose, making the work easier. This has the effect of improving efficiency and reducing costs.
