【発明の属する技術分野】
本発明は、研削盤の構造に関し、より詳細にはベッドの構造に関する。
【０００２】
【従来の技術】
一般的に、工作機械のベッド１００の構造は、図３に示すように、重量を考慮して箱状で補強リブ１０１等を適宜に配置して鋳物等で作成している。
例えば、工作機械のうち、よく知られた研削盤を例として取り上げると、この研削盤は前後動する砥石台（図示略）と、ワークを挟持し左右動する主軸台（図示略）と心押台（図示略）で構成されている。
そして、この研削盤のベッド１００の上に天井板を載置固定し、この天井板の上に、砥石台と主軸台と心押台を取付けるため、これらの部品の重量を考慮して、略Ｔ字状の箱状で、補強リブ１０１を適宜の間隔で設けていると共に、ベッドの支持箇所にはジャッキ（図示略）が取り付けてあり、このジャッキで高低調整やベッドの静的な変位（歪み）の調節をしたり、研削盤の稼動時の動的な変位を見込んだ調節をしている。そして、そのジャッキの数は、例えば、１３箇所に及んでいる。
尚、前記説明の研削盤のベッドの構造は、従来よく知られた構造であるので、あえて、先行技術文献を記載しない。
【０００３】
【発明が解決しようとする課題】
前記従来の研削盤のベッド１００は、１３箇所のジャッキで、変形やレベル調整可能に構成してあるが、この高低調整は熟練を要すると共に、その数の多さに長時間を要する。又、径年変化のため、ベッド１００の変形調整が定期的に必要となる。
又、ベッド１００は、重量がある砥石台と心押台と主軸台及びテーブルを考慮して、Ｔ字状の箱状に構成してあると共に、荷重に耐えるように補強リブ構造のため、その構造は複雑で、鋳物の製作における型が複雑であるし、その複雑な構造のために各部の歪みも複雑となり、製作コスト面と加工精度の面で問題がある。
【０００４】
そこで、先ず、従来のベッドの変位量等を、砥石台の重心Ａ、主軸台の重心Ｂ、心押台の重心Ｃ及びテーブルの重心を考慮し測定した。
（１）ワークと砥石間の相対変位量
（イ）砥石台の重心位置（Ａ）、主軸台の重心位置（Ｂ）、心押台の重心位置（Ｃ）とし、
（ロ）相対変位（水平面に対する変位）を、〔（Ｂ点の変位＋Ｃ点の変位）／２−（Ａ点の変位）〕と定義すると、
（ハ）砥石台を前進と後退変動させて、前記相対変位〔（Ｂ点の変位＋Ｃ点の変位）／２−（Ａ点の変位）〕を計算することができる。
（２）ベッドの上下方向の変形量
又、図３に示すように、砥石台を前後に移動すると共に、主軸台と心押台を左右動させて計算することができる。
【０００５】
そこで、本発明は、前記の変形量等を減少させると共に、製造が簡便なベッドの構造を提供するものである。
【０００６】
【課題を解決するための手段】
請求項１の研削盤のベッドの構造は、底板の上に、例えば、図１に示すように、砥石台側支柱１０、主軸台側支柱１１、心押台側支柱１２の３箇所の支柱を立設し、この支柱の上に天板を載置固定して構成し、前記支柱は円形または多角形の筒状体である。また、前記３箇所の支柱は、研削盤全体の重心がこれらの３箇所の支柱で形成される三角形の中に入るように配置してある。
そして、前記底板の上に又は前記支柱の側面に、天板を支える板状で逆台形状の補強板を砥石台または主軸台の移動方向に沿って設けてある。
また、請求項２の研削盤のベッドの構造は、支柱の補強として、筒状体の内部に長手方向に板状の補強体を一体形成する。
【０００７】
請求項３の研削盤のベッドの構造は、補強板の下隅部を肉盛することによって、補強板を更に補強することができる。
請求項４の研削盤のベッドの構造は、支柱と他の支柱を前記底板と共に板状の補強体で連結することによって、簡便な方法で強度を増すことができる。
【０００８】
【発明の実施の形態】
本発明の実施の形態を図面を用いて説明する。図１は、工作機械、例えば、研削盤のベッド１の平面矢視図であり、底板３の上には、後記で詳述する３本の支柱１０、１１、１２が立設してあり、これらは鋳物等で製造してある。
尚、このベッド１に立設の支柱１０、１１、１２の上には、天板（図示略）が載置固定され、この天板の上には、前後動する砥石台、ワークを挟持し左右動するテーブルの上に主軸台（図示略）と心押台（図示略）が載置固定される。尚、主軸台（図示略）と心押台（図示略）が左右動する構成であってもよい。そして、全体を覆うカバーが設けられている。
研削盤は、前記砥石台と主軸台と心押台が主たる重量物であり、本発明は、前記従来例で記載したように、砥石台の重心、主軸台の重心、心押台の重心及びテーブルの重心に対し、変位量を最小にする構造を提供するものである。
【０００９】
そこで、研削盤のベッドの形状を種々の条件で検討した結果、図１に示すように、底板３上に、３点で支持し、それらの間に空間を形成する構造が好ましいことを見いだした。
このベッド１は、図１に示すように、略Ｔ字状の底板３の上に、砥石台のほぼ後退端での重心に位置する砥石台側支柱１０と、図示略の主軸台と心押台の下方位置に主軸台側支柱１１と心押台側支柱１２を立設して構成する。そして、これらの支柱１０、１１、１２の断面形状は円形または多角形でよいが、最も簡便で座屈応力を考慮して６角形の筒状体を選定すると共に、この６角形の筒状体を更に補強するために、内部に、長手方向に板状の補強体５が一体で形成してある。
尚、この補強体５の数は、少なくとも１本でよいが、前記筒体の厚み、大きさ（外周円径）等を考慮して、各隅部を連結する３本で構成する構造である。従って、支柱１０、１１、１２の断面形状は、３角形状の空間が６個で構成してある。
【００１０】
次に、前記３箇所の支柱（砥石台側支柱１０、主軸台側支柱１１、心押台側支柱１２）の中心位置について説明する。
（イ）先ず、砥石台側支柱１０と主軸台側支柱１１と心押台側支柱１２の中心を結んで平面三角形を作成し、この三角形の中に、移動する砥石台と主軸台と心押台を考慮しての、研削盤全体の重心が入るように配置にする。
（ロ）又、主軸台と心押台方向に対するベッドの長さを、梁の長さ（Ｌ）として、この梁に等分布荷重がかかると仮定し、梁のたわみが最小となる支持位置に主軸台側支柱と心押台側支柱の中心をおく。この位置は、ベッドの長さ（Ｌ）に対し、ベッドの端部から主軸台側支柱１１（又は心押台側支柱１２）の中心位置迄の距離Ａは、０．２５＊Ｌである。即ち、主軸台側支柱１１と心押台側支柱１２はベッドの端部から、０．２５＊Ｌの位置に設置する。
（ハ）又、主軸台側支柱と心押台側支柱の中心位置は、ベッドの上を主軸台と心押台が載置されたテーブルが、往復動するのを支持し、且つ、テーブルが傾斜しない位置に設置する。
【００１１】
又、前記各支柱１０、１１、１２の相対する両側面には、補強として、短い方を底板側に、長い方を天板側とする逆台形状の補強板１５が、底板３の上に一体で形成してある。又、この補強板１５は、支柱１０、１１、１２の側面に天板（図示略）を支える。
即ち、砥石台（図示略）が前後動する方向の砥石台側支柱１０の両側面に、逆台形状の補強板１５ａが、主軸台（図示略）の左右動する方向の両側面に逆台形状の補強板１５ｂが、心押台（図示略）が左右動する方向の両側面に補強板１５ｃが、底板３及び各支柱１０、１１、１２と一体で形成してあり、天板を支える。
前記逆台形状の補強板１５により、重量物が移動しても、その重量を各支柱１０、１１、１２で支持することができる。即ち、移動する砥石台の重量を支柱１０が支持し、主軸台及び心押台を載置したテーブルの重量を支柱１１、１２が分配して支持する。
【００１２】
前記のように、底板３をＴ字状（三角状）に形成し、この底板３に砥石台側支柱１０と主軸台側支柱１１と心押台側支柱１２を立設して３点支持構造とし、且つ、側面には逆台形状の補強板１５を立設することによって、底板３や逆台形状の側板等の歪みが少なくなると共に、天板（図示略）とで、箱状のベッドを形成すると、変位量等が少なく構成することができると共に、ベッド内には空間が形成されるので重量の増加を抑制することができる。
尚、前記砥石台側支柱１０は、更なる補強が必要であり、６角形の隅部から前記補強板１５ａと平行方向に補強板１６が延設して、補強を実施してある。
前記逆台形状の補強板の長い方の長さと短い方の長さ及び高さ及び厚みは、天板の上に載置する機器等の荷重及び支柱等の変形量によって選定する。
【００１３】
前記ベッドの上下方向の変形量を減少させる対策として、他の実施の形態として図２に示すように、略台形状の正面開口部の補強及び中央部の空間に対する補強が有効である。
この正面開口部の補強として、図２に示すように、台形部の下隅部２０を尖塔の切欠を埋めるように肉盛する。尚、この台形部の下隅部２０の肉盛は、図２に示す正面の開口部に限定されず、他に立設の補強板１５にも適用可能である。
【００１４】
又、ベッド１の空間部の補強として、前記砥石台側支柱１０に付設の補強板１６と反対側の隅部と主軸台側支柱１１の最右隅部とを連結形成の補強板１８と心押台側支柱１２の最左隅部とを連結形成の板状の補強板１８が、底板３と共に一体に形成してある。
この様に、支柱と支柱及び底板３を補強板１８で連結することによって、より強度な構造にすることができるし、板状の補強板１８で構成するため、ベッド内（底板３の上）には空間を形成することができる。
【００１５】
以上のような構造でベッドを構成すると、砥石台側支柱１０と主軸台側支柱１１と心押台側支柱１２の３点支持で構成できるので、製作が簡便であると共に、ベッド上には空間が形成されて重量の増加の抑制を図ることができるし、且つ、変形量の最小化を図ることができる。
【００１６】
尚、本発明は前記例示の研削盤に適用し、荷重点を考慮して三角形の３点支持でベッドを構成したが、他の研削盤にも適用でき、若し、多くの荷重点を備えている研削盤には、前記３点支持の三角形を基本として、新たな荷重支持点を前記三角形の頂点とで三角形を形成するように構成することによって、本願発明と同じ効果を得ることができる。又、前記逆台形状の補強板１５は、必ずしも左右対称形である必要はないと共に、補強板１５の厚み、及び取り付ける位置も荷重等を考慮して適宜選定する。又、前記に記載したベッドの構造に適用の補強板等の構成は、適宜組み合せて、ベッドを構成してもよい。
【００１７】
【発明の効果】
請求項１の研削盤のベッドの構造は、３箇所の支持構造であるので空間を有するベッド構造となり、製造が簡便であると共に重量増加の抑制を図ることができ、且つ、補強板によって、変形量を減少させる構造にすることができる。
請求項２の研削盤のベッドの構造は、筒状体の内部に長手方向に板状の補強体が一体形成することによって、強固な支柱となる。
請求項３の研削盤のベッドの構造は、補強板の下隅部を肉盛することによって、補強板を更に補強することができる。
請求項４の研削盤のベッドの構造は、支柱と他の支柱を底板と共に板状の補強体で連結することによって、簡便な方法で強度を増すことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a grinding machine structure, and more particularly to a bed structure.
[0002]
[Prior art]
In general, the structure of the bed 100 of the machine tool is made of a casting or the like by appropriately arranging a reinforcing rib 101 or the like in a box shape in consideration of the weight, as shown in FIG.
For example, taking a well-known grinder as an example of a machine tool, this grinder includes a grinding wheel head (not shown) that moves back and forth, a head stock (not shown) that holds a workpiece and moves left and right, and a tailstock. It consists of a table (not shown).
A ceiling board is placed and fixed on the bed 100 of this grinding machine, and a grindstone base, a headstock, and a tailstock are mounted on the ceiling board. It is a T-shaped box with reinforcing ribs 101 provided at appropriate intervals, and a jack (not shown) is attached to the bed support location. With this jack, height adjustment and static displacement of the bed ( (Strain) is adjusted, and adjustments are made to allow for dynamic displacement during operation of the grinding machine. And the number of the jack has reached 13 places, for example.
Since the structure of the grinding machine bed described above is a well-known structure, prior art documents are not described.
[0003]
[Problems to be solved by the invention]
The bed 100 of the conventional grinding machine is composed of 13 jacks that can be deformed and level-adjusted. This level adjustment requires skill and requires a long time due to its large number. In addition, due to the change in diameter, it is necessary to periodically adjust the deformation of the bed 100.
In addition, the bed 100 is formed in a T-shaped box in consideration of the heavy grinding wheel head, the tailstock, the headstock, and the table, and has a reinforcing rib structure to withstand the load. The structure is complicated, the mold in casting production is complicated, and the distortion of each part is also complicated due to the complicated structure, and there are problems in terms of production cost and processing accuracy.
[0004]
Therefore, first, the displacement amount of the conventional bed was measured in consideration of the center of gravity A of the grinding wheel head, the center of gravity B of the headstock, the center of gravity C of the tailstock, and the center of gravity of the table.
(1) Relative displacement between workpiece and grindstone (a) Gravity center position (A) of grindstone head, gravitational center position (B) of headstock, and gravitational center position (C) of tailstock
(B) When the relative displacement (displacement with respect to the horizontal plane) is defined as [(displacement of point B + displacement of point C) / 2− (displacement of point A)],
(C) The relative displacement [(displacement at point B + displacement at point C) / 2− (displacement at point A)] can be calculated by moving the grinding wheel head forward and backward.
(2) The amount of deformation in the vertical direction of the bed As shown in FIG. 3, the calculation can be performed by moving the grindstone table back and forth and moving the headstock and tailstock horizontally.
[0005]
Accordingly, the present invention provides a bed structure that is easy to manufacture while reducing the amount of deformation.
[0006]
[Means for Solving the Problems]
The structure of the bed of the grinding machine according to claim 1 is such that, for example, as shown in FIG. 1, three pillars of a grindstone base side pillar 10, a spindle base side pillar 11, and a tailstock side pillar 12 are formed on the bottom plate. The column is erected and a top plate is placed and fixed on the column. The column is a circular or polygonal cylindrical body. Further, the three columns are arranged such that the center of gravity of the entire grinding machine falls within a triangle formed by these three columns.
A plate-like and inverted trapezoidal reinforcing plate that supports the top plate is provided on the bottom plate or on the side surface of the column along the moving direction of the grinding wheel head or the headstock.
The structure of the bed of the grinding machine according to claim 2 integrally forms a plate-like reinforcing body in the longitudinal direction inside the cylindrical body as a reinforcement of the support.
[0007]
The structure of the bed of the grinding machine according to claim 3 can further reinforce the reinforcing plate by building up the lower corner portion of the reinforcing plate.
The structure of the bed of the grinding machine according to claim 4 can increase the strength by a simple method by connecting the strut and the other strut together with the bottom plate with a plate-like reinforcement.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a machine tool, for example, a bed 1 of a grinding machine. On a bottom plate 3, three columns 10, 11, and 12 described in detail later are erected. These are manufactured by casting or the like.
A top plate (not shown) is placed and fixed on the support columns 10, 11, and 12 standing on the bed 1, and a grinding wheel base and a workpiece that move back and forth are sandwiched on the top plate. A headstock (not shown) and a tailstock (not shown) are placed and fixed on a table that moves left and right. In addition, the structure which a spindle stock (not shown) and a tailstock (not shown) move right and left may be sufficient. And the cover which covers the whole is provided.
The grinding machine is a heavy article mainly composed of the grinding wheel head, the headstock, and the tailstock, and as described in the conventional example, the present invention includes the center of gravity of the grinding wheel base, the center of gravity of the headstock, the center of gravity of the tailstock, and A structure that minimizes the amount of displacement with respect to the center of gravity of the table is provided.
[0009]
Therefore, as a result of examining the shape of the bed of the grinding machine under various conditions, as shown in FIG. 1, it was found that a structure that supports the bottom plate 3 at three points and forms a space therebetween is preferable. .
As shown in FIG. 1, the bed 1 includes a grinding wheel base side column 10 positioned at the center of gravity at a substantially backward end of the grinding wheel base, a spindle base and a tailstock (not shown) on a substantially T-shaped bottom plate 3. A headstock-side column 11 and a tailstock-side column 12 are erected at a position below the table. The cross-sectional shapes of these columns 10, 11 and 12 may be circular or polygonal , but the hexagonal cylindrical body is selected in consideration of the simplest and buckling stress, and this hexagonal cylindrical body is selected. In order to further reinforce, a plate-like reinforcing body 5 is integrally formed in the inside in the longitudinal direction.
The number of the reinforcing members 5 may be at least one, but the structure is constituted by three connecting the respective corners in consideration of the thickness, size (outer circumference diameter), etc. of the cylindrical body. . Therefore, the cross-sectional shape of the columns 10, 11, and 12 is composed of six triangular spaces.
[0010]
Next, the center positions of the three columns (grinding wheel side column 10, spindle head side column 11, tailstock side column 12) will be described.
(A) First, a plane triangle is created by connecting the centers of the grinder base column 10, the spindle column 11 and the tailstock column 12, and in this triangle, the moving grindstone, spindle column and tailstock are moved. Arrange it so that the center of gravity of the entire grinding machine enters, taking into account the table.
(B) The length of the bed with respect to the headstock and tailstock direction is assumed to be the length (L) of the beam, and it is assumed that an evenly distributed load is applied to the beam. Center the headstock column and tailstock column. In this position, the distance A from the end of the bed to the center position of the headstock column 11 (or the tailstock column 12) is 0.25 * L with respect to the bed length (L). That is, the headstock-side column 11 and the tailstock-side column 12 are installed at a position of 0.25 * L from the end of the bed.
(C) The center position of the headstock column and the tailstock side column supports the reciprocating movement of the table on which the spindle table and the tailstock are placed on the bed. Install in a position that does not tilt.
[0011]
Further, on the opposite side surfaces of each of the pillars 10, 11, 12 is an inverted trapezoidal reinforcing plate 15 on the bottom plate 3 with the shorter side as the bottom plate side and the longer side as the top plate side as reinforcement. It is integrally formed. The reinforcing plate 15 supports a top plate (not shown) on the side surfaces of the support columns 10, 11, and 12.
That is, an inverted trapezoidal reinforcing plate 15a is placed on both sides of the headstock (not shown) in the left-right direction on both sides of the wheelhead-side column 10 in the direction in which the wheelhead (not shown) moves back and forth. The reinforcing plate 15b having a shape is formed integrally with the bottom plate 3 and the respective columns 10, 11, and 12 on both side surfaces in the direction in which the tailstock (not shown) moves left and right, and supports the top plate. .
Even if a heavy object moves, the inverted trapezoidal reinforcing plate 15 can support the weight by the columns 10, 11, and 12. That is, the column 10 supports the weight of the moving grindstone platform, and the columns 11 and 12 distribute and support the weight of the table on which the headstock and the tailstock are placed.
[0012]
As described above, the bottom plate 3 is formed in a T shape (triangular shape), and the grindstone base column 10, the spindle block 11 and the tailstock column 12 are erected on the bottom plate 3 to provide a three-point support structure. In addition, by installing the inverted trapezoidal reinforcing plate 15 on the side surface, distortion of the bottom plate 3 and the inverted trapezoidal side plate is reduced, and the top plate (not shown) is used to form a box-shaped bed. When the is formed, the displacement amount can be reduced, and a space is formed in the bed, so that an increase in weight can be suppressed.
The whetstone-side support column 10 needs to be further reinforced, and the reinforcing plate 16 extends from the corner of the hexagon in a direction parallel to the reinforcing plate 15a to reinforce.
The longer length and the shorter length, height, and thickness of the inverted trapezoidal reinforcing plate are selected according to the load of the device or the like placed on the top plate and the amount of deformation of the column.
[0013]
As a measure for reducing the amount of deformation in the vertical direction of the bed, as shown in FIG. 2 as another embodiment, reinforcement of a substantially trapezoidal front opening and reinforcement of a central space are effective.
As reinforcement of the front opening, as shown in FIG. 2, the
[0014]
Further, as a reinforcement of the space portion of the bed 1, a reinforcing plate 18 formed by connecting a corner opposite to the reinforcing plate 16 attached to the grindstone-side column 10 and a rightmost corner of the headboard-side column 11 and the center. A plate-like reinforcing plate 18 that is formed by connecting the leftmost corner portion of the pedestal side column 12 with the bottom plate 3 is integrally formed.
In this way, by connecting the support column, the support column, and the bottom plate 3 with the reinforcing plate 18, it is possible to make a stronger structure, and because the plate-shaped reinforcing plate 18 is used, the inside of the bed (on the bottom plate 3). A space can be formed.
[0015]
If the bed is configured in the above-described structure, it can be configured by three-point support of the grindstone support column 10, the spindle table support column 11, and the tailstock support column 12, so that the manufacture is simple and the space on the bed is The increase in weight can be suppressed, and the amount of deformation can be minimized.
[0016]
In addition, the present invention is applied to the above-described grinder, and the bed is configured with a triangular three-point support in consideration of the load point. However, the bed can be applied to other grinders and has many load points. the grinding machine in which, as a basic triangle of the three-point support, by configuring so as to form a triangle with a new load support points in the vertex of the triangle, it is possible to obtain the same effect as the present invention . The inverted trapezoidal reinforcing plate 15 is not necessarily symmetrical, and the thickness of the reinforcing plate 15 and the mounting position are appropriately selected in consideration of the load and the like. Further, the bed may be configured by appropriately combining the configurations of the reinforcing plate and the like applied to the bed structure described above.
