本発明は樹脂被覆材の加工方法に係シ、特に、被加工物
の表面に被覆された樹脂被覆材を高精度に加工するのに
好適な樹脂被覆材の加工方法に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for processing a resin coating material, and in particular, a method suitable for processing a resin coating material coated on the surface of a workpiece with high precision. This invention relates to a method for processing resin coating materials.
ハンドルの操舵力をビニオンシャフトに伝達スる為の軸
継手を形成する場合、第１図及び第２図に示されるよう

ハンドルの操舵力をビニオンシャフトに伝達する必要が

がある。そζで、軸継手１４を形成する際、管１２の内
径と軸１０の外径をほぼ同寸法に成形し、軸１０の表面

台せて嵌合することが従来性なわれていた。しかし、こ
のような方法によって軸１０と管１２とを嵌合するので
は、作業性が低下するという不具合があった。When forming a shaft joint for transmitting the steering force of the handle to the pinion shaft, as shown in FIGS. 1 and 2, a shaft 10 connected to the handle and a pipe connected to the pinion shaft are used. 12 is required to be tightly fitted. That is, the shaft joint 14 shown in FIG. 1 rotates while expanding and contracting in the axial direction according to the steering force of the steering wheel.
It is necessary to transmit the steering force of the handle to the pinion shaft, and it is also necessary to keep the backlash in the rotational direction to less than several tens of microns. Therefore, when forming the shaft joint 14, the inner diameter of the tube 12 and the outer diameter of the shaft 10 are molded to approximately the same size, wrapping powder is applied to the surface of the shaft 10, and the shaft 10 and tube 12 are placed on a physical stand. Conventionally, it was customary to fit the parts by aligning them together. However, fitting the shaft 10 and the tube 12 together by such a method has the disadvantage that workability is reduced.
そこで、第３図に示されるように、軸１０と管１２との
間に一定の間隙が生じる程度に軸１０の外径を成形する
と共に、第４図に示されるように軸１０の表面に接着剤
１６を介してナイロン系の樹脂をコーティングすること
が提案された。Therefore, as shown in FIG. 3, the outer diameter of the shaft 10 is shaped to such an extent that a certain gap is created between the shaft 10 and the tube 12, and as shown in FIG. It has been proposed to coat with nylon resin via adhesive 16.
ところが、軸１０の回転方向におけるガタを数十ミクロ

の圧縮強度を維持することができる。However, in order to suppress the backlash in the rotational direction of the shaft 10 to several tens of microns or less and to maintain the compressive strength of the resin coating 18, the thickness of the resin coating 18 is set to be about Q, 2 mm. By coating the surface of the shaft 10 with a resin coating material 18 of about 2 mm by a method such as injection molding, the play in the rotational direction of the shaft joint 14 can be suppressed to several tens of microns or less, and Resin coating material 18
The compressive strength can be maintained.
ところが、軸１０の表面に最初からＱ、 ２１ＴＩ ｍ

１ｍｍ程度切削加工することが提案されている。However, from the beginning on the surface of the shaft 10, Q, 21TI m
If the resin coating material 18 is coated with a thickness of about 0.2 mm, the thickness of the resin coating material 18 on the end portions 20, 22, etc. cannot be maintained at about 0.2 mm. Therefore, it has been proposed to coat the surface of the shaft 10 with a 1.2 mm 8 degree resin coating material 18 and to cut each part by about 1 mm.
ところが、室温、例えば２５℃の雰囲気の中におかれた

ったシすることがあった。However, when the surface of the resin coating material 18 placed in an atmosphere at room temperature, for example 25° C., is cut, the resin coating material 1
8 peeled off from the adhesive surface, or even if it did not peel off, it remained on the shaft 10 because it was fixed by the adhesive 16.
The resin sheathing material 18 having a thickness of m may have shear lines due to cutting resistance, and the resin sheathing material 18 may be peeled off when it is fitted to the pipe 12.
そこで、第５図に示されるように、ポット型多段ブロー

8 to a predetermined thickness.

がかかるという不具合がある。When the resin coating material 18 coated on the shaft 10 is cut using this multistage broach 24, the resin coating material 18 is gradually cut by each stage of broaches, so that the resin coating material 18 can be cut without peeling. be able to. However, when cutting is performed using a multistage broach, the resin coating material 18 must be cut with each stage of broaches.
A long cutting stroke is required, and it is also necessary to enlarge the mechanical equipment for cutting. Furthermore, cutting with a multistage broach has the disadvantage that it takes time and effort to dispose of chips after cutting.

程度である。In FIG. 6, a shaft 32 whose axial end is supported by a support device 30 is used as a shaft of a shaft joint, etc., and the surface of the shaft 32 is bonded via an adhesive 1 (not shown). A resin coating material 18 is coated by injection molding. In this embodiment, the temperature of the resin coating material 18 coated on the surface of the shaft 32 is maintained within the range from the glass transition point to the melting point of the resin. That is, when using nylon 12 as the resin coating material 18, the glass transition point is 50 to 60°C, and the melting point is 170°C.
That's about it.

。When the temperature of the resin coating material 18 is maintained within a range from the glass transition point to the melting point, the resin coating material 18 changes from a glass-like hard state to a rubber-like state. Therefore, even when cutting along the resin coating material 18 with the cutting tool 34, the cutting resistance is small, so the resin coating material 18 can be cut without peeling or peeling off the resin coating material during cutting. be able to. Furthermore, even when the resin coating material 18 is cut to a thickness of 0.2 mm by cutting the resin coating material 18 to a thickness of 0.2 mm by using the cutting tool 34, the resin coating material 1
Since the temperature in step 8 is maintained within the range from the glass transition point to the melting point, this can be done by one cutting.
