本発明はバルブリフタにおけるバルブロツドの
頂部と当接される端部の着座面を仕上加工する方
法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for finishing the seating surface of a valve lifter at the end that abuts the top of the valve rod.

はその加工に際し肉が中心部に流れて該中心部に
凸部を発生し、これは精度機能上好ましくない不
都合を伴う。 Conventionally, this type of finishing method generally involves grinding with a small-diameter grindstone after heat treatment, but such a method requires a considerable amount of time and is inevitably inefficient. Conventionally, burnishing methods using burnishing tools have been proposed in order to eliminate such inconveniences, but with such methods, the meat flows to the center and a convex portion is generated in the center, which is a problem. This is accompanied by undesirable disadvantages in terms of accuracy.

ることを特徴とする。 An object of the present invention is to provide a method for finishing the seating surface of the end of a valve lifter, in which the finishing process is performed by burnishing using a burnishing tool. In addition, prior to the processing, a recess is formed in the center of the seating surface to allow the meat to escape.
本発明実施の１例を別紙図面に付説明する。 An example of implementing the present invention will be explained with reference to the attached drawings.
図面で１はバルブリフタを示し、該リフタ１は

はその上面の動弁カムを示す。 In the drawings, reference numeral 1 indicates a valve lifter, and the lifter 1 has a slightly thick seating surface 2 at the center of its end, and the seating surface 2 is brought into contact with the top of the valve rod a, as shown in FIG. 6, for example. However, the seating surface 2 is prepared in advance so that the upper surface is flat as shown in the second figure, and then finishing is performed on this surface.
In FIG. 6, b is a guide on the outer periphery of the rod a;
c is a tappet shim on the upper surface of the valve lifter 1, d
indicates the valve train cam on the top surface.

に例えば10〜20μ程度の高さの凸部ｊを生じ、こ
れは好ましくない。 According to the present invention, the above-mentioned finishing process is performed by a burnishing process using a burnishing tool. For example, as shown in FIG. A burnishing tool h having an inclined tip of a burnishing head g is applied from above. The head g
is given rotation and vertical feeding motion by a main shaft i extending upward, and this point is not particularly different from known ones. Thus, according to the burnishing process using the tool h, the seating surface 2 is given a predetermined finishing process, but as it is, the upper surface of the surface 2 is damaged by the flow of the meat, for example, as shown in FIG. For example, a protrusion j having a height of about 10 to 20 μm is produced, which is not preferable.

た。 According to the present invention, in order to eliminate such inconveniences, a recess 3 is previously formed in the center of the material, as shown clearly in FIG. 2, prior to processing. This recess 3 allows the meat to escape during the burnishing process described below, and the seating surface 2 is made to have a more or less rounded finish, for example, as shown in the third figure. As shown in the figure, it is assumed that the center portion is left somewhat recessed. As an example, the material of the valve lifter 1 is (low carbon steel), the area of the seating surface 2 is 30 mm 2 , and the area of the recess 3 is
When burnishing was applied to this , the surface roughness improved from 20S to 0.8-3S. In this case, the burnishing amount was 0.05 to 0.1 mm, the burnishing pressure was 800 to 1000 kg, and the working time was 2 seconds.

効果を有する。 As described above, according to the present invention, the finishing process of the seating surface is performed by burnishing using a burnishing tool, which makes the work easier and more efficient than the conventional grinding process. Since the seating surface is pre-formed with a concave portion in the center, the flow of meat is absorbed into the concave portion and there is no possibility that a convex portion will be formed in the central portion, so that there are no functional inconveniences.
