る。Problems that the invention aims to solve In the plug structure described in the conventional technology, the thermal expansion coefficients differ depending on the materials that make up the plug and the sliding surface, and the top surface of the filler material (plug) changes due to temperature changes. There is a problem in that it protrudes onto the sliding surface and deteriorates the accuracy of the sliding surface. In addition, the plug may conversely dent due to temperature changes, and there is also the problem that the plug may fall out due to repeated thermal deformation.
本考案は、従来の技術の有するこのような問題

とするものである。 The present invention was devised in view of the problems of the conventional technology, and its purpose is to provide a structure for a plug that does not protrude, dent, or fall out due to thermal deformation due to temperature changes. It is something to do.

材を充填して構成したものである。Means for Solving the Problems In order to achieve the above object, the plug structure of the sliding surface in the present invention is such that a locking engagement part is provided near the sliding surface of the counterbore hole, and a retaining engagement part is provided below the counterbore hole. It is constructed by embedding a thermal deformation absorbing material in the bottom and filling the upper part of the thermal deformation absorbing material with a filler.

違する座ぐり穴と充填材とはそれぞれ熱変形量の

準に下底に向かつて伸び縮みし、この伸縮量は熱
変形吸収材により吸収される。Effect Due to changes in the environmental temperature due to operation, etc., the temperature of the counterbore and the filling material changes, and the counterbore hole and the filling material, which have different coefficients of thermal expansion, differ in the amount of thermal deformation. The filler expands and contracts relative to the counterbore, but since the axial movement of the filler is regulated by the retaining engagement part, it expands and contracts toward the bottom with the retaining engagement part as a reference. This amount of expansion and contraction is absorbed by the thermal deformation absorbing material.

時硬化形の充填材５が充填されている。Embodiment An embodiment will be described with reference to FIGS. 1 and 2. The guide rail 2 of the bed 1 is fixed by a bolt 3 that is inserted into a mounting hole having a countersunk hole 2b drilled from the sliding surface 2a side. An inner circumferential groove 2c having a triangular cross-sectional shape is carved at the position. A heat deformation absorbing material 4 made of a foamed elastic material such as sponge is embedded in the bottom of the counterbore hole 2b so as to wrap around the head of the bolt 3, and an inner circumferential groove 2 above the heat deforming absorbing material
The upper side of the counterbore hole having a diameter c is filled with a filler material 5 that hardens over time, such as plastic.

Of course, it is not necessary to use an inner circumferential groove as long as a suitable engaging portion is provided.
続いて本実施例の作用について説明する。 Next, the operation of this embodiment will be explained.

理解できるであろう。 The temperature of the guide rail 2 and the filler 5 changes due to changes in the environmental temperature due to operation or the like. Since the guide rail and the filler have different coefficients of thermal expansion, the amount of thermal deformation of each differs depending on temperature changes, resulting in a difference in the axial dimensions of the filler and the counterbore.
The filling material 5 is regulated in the axial direction by an inner circumferential groove 2c carved at a distance L near the sliding surface 2a, and the expansion and contraction of the filling material with respect to the counterbore hole due to thermal deformation is directed toward the thermal deformation absorbing material 4 side. It appears large and is minute on the sliding surface side. This is compared to the filler 103 cited in the prior art shown in FIG. 3, which expands and contracts significantly upward with the bottom surface as a reference due to the difference in thermal deformation with respect to the axial distances L 1 and L 2 . It will be easy to understand how minute the amount of expansion and contraction with respect to L is.

ことができる。 Thermal deformation absorbing material is buried in a counterbore hole that has a retaining engagement part near the sliding surface, and filler is filled on top of it, so the amount of filler on the sliding surface is smaller than in the past. The amount of protrusion or denting is reduced,
The clearance (oil film) necessary for sliding is ensured, and an adverse effect on the accuracy of the sliding surface can be prevented. It is also possible to prevent the plug from falling out due to repeated thermal deformation.
