Description

また円筒研削盤において、主軸台の基準座と心押台の心押センタに設けた測定用円筒部に砥石台に設けたタッチセンサを当接させることでテーパ補正を行うものがある。（例えば、特許文献２参照）In cylindrical grinder, there is performed a taper correction by causing contact the touch sensor provided in the wheel head to the measurement cylindrical portion provided on the heart press center of the headstock of the reference locus and the tailstock. (For example, see Patent Document 2)

故に、本第一の発明によれば、例えば主軸台に実装されたセンタの回転軸の精度と第一の嵌合手段の柱状の構造物又はその構造を有する物と嵌合するための穴の精度がともに数ミクロンメートルの精度であれば、測定器を用いることなくこれらと同程度の芯ずれの精度を簡便に実現することができ、更にこれらの物品の加工精度を更に上げれば、その加工精度の上昇に伴って当該芯ずれの精度も向上させることができるものである。Therefore, according to the first invention, for example, the accuracy of the rotation shaft of the center mounted on the headstock and the hole for fitting with the columnar structure or the structure having the structure of the first fitting means are provided. If both the accuracy is several micrometers, the same misalignment accuracy can be easily achieved without using a measuring instrument. If the processing accuracy of these articles is further increased, the processing As the accuracy increases, the accuracy of the misalignment can also be improved.

図１中１ａと１ｂは分離した第一の嵌合手段であり、２ａと２ｂは正方形の中心に円形の穴の開いた軸受手段２の断面であり、３ａと３ｂは止めねじであり、４は第二の嵌合手段であり、５ａと５ｂは円筒型のワーク５の断面であり、６ａと６ｂは第一の嵌合手段が柱状の構造物等と嵌合するための穴であり、７は第二の嵌合手段４が柱状の構造物等と嵌合するための穴であり、８ａと８ｂは第一の嵌合手段１ａとワーク５との締め付け用ねじ穴であり、９ａと９ｂは第一の嵌合手段１ｂと第二の嵌合手段４の締め付けようねじ穴であり、１０はバカ穴であり、１１ａと１１ｂと１１ｃと１１ｄはパッキンである。1 in 1a and 1 b is a first fitting means separated, 2a and 2b is a cross section of the bearing means 2 an open circular hole in the center of the square, 3a and 3b are set screw, 4 is a second fitting means, 5a and 5b are cross sections of the cylindrical workpiece 5, and 6a and 6b are holes for fitting the first fitting means to a columnar structure or the like. , 7 are holes for fitting the second fitting means 4 to a columnar structure or the like, 8a and 8b are screw holes for fastening the first fitting means 1a and the work 5, and 9a And 9b are screw holes for fastening the first fitting means 1b and the second fitting means 4, 10 is a fool hole, and 11a, 11b, 11c and 11d are packings.

本第一の発明を円筒研削盤に実施するに当たり心押台のセンタ穴に実装でき先端形状が穴６ａ及び穴６ｂに嵌合するテーパー形状を有する円柱形の治具（以降治具Ａと称する）を用意する。When the first invention is applied to the cylindrical grinding machine, it can be mounted in the center hole of the tailstock, and a cylindrical jig having a tapered shape that fits into the hole 6a and the hole 6b (hereinafter referred to as jig A). ) is prepared.
