Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は工場等において、溶接、組立、仕上、検査作業等に用いられる作業台 に関する。 The present invention relates to a workbench used for welding, assembly, finishing, inspection work, etc. in a factory or the like.

【0002】[0002]

【従来の技術】[Prior art]

作業台の代表例として、テーブル面の高さ調整の可能なテーブルリフター式作 業台01を図5の斜視図によって説明すると、架台a上にクロス状に設けたフレ ームb上にテーブルcを設け、フレームb内にシリンダーdを付設したものであ り、ワークeの高さに応じてシリンダーdによりテーブルcの高さが調整出来る ものである。 As a typical example of the workbench, a table lifter type workbench 01 whose height of the table surface can be adjusted will be described with reference to the perspective view of FIG. And a cylinder d is attached inside the frame b, and the height of the table c can be adjusted by the cylinder d according to the height of the work e.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記従来の作業台には解決すべき次の課題があった。 The conventional workbench described above has the following problems to be solved.

【0004】 即ち、従来のテーブルリフター式作業台01は単純であり、高さ方向の平行移 動のみでワークの高さには対応できるが傾動が出来ない。従ってワークに斜面が ある場合、斜面を水平にすることが出来ないという問題があった。That is, the conventional table lifter type workbench 01 is simple and can cope with the height of the work only by parallel movement in the height direction, but cannot tilt. Therefore, when the work has a slope, there is a problem that the slope cannot be made horizontal.

【0005】 本考案は上記の問題点を解決した昇降、傾動が可能な作業台を提供することを 目的とする。An object of the present invention is to provide a workbench capable of raising and lowering and tilting to solve the above problems.

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記課題の解決手段として、同一円周上にヘッドを上方にして等分に 直立配置された3本のジャッキと、同3本のジャッキを一体的に連結するフレー ムと、3本のジャッキの各頂部に付設された球状の自由回転体と、同各自由回転 体上を覆って載置されたテーブルと、同テーブルが水平状態にあるときその裏面 の上記円周の中心と各自由回転体中心とを結ぶ線を2等分線としてテーブルの中 心側に頂点を有し両斜辺の内側が上記自由回転体の周面に内接して堤体状にテー ブル裏面に固設された所要高さを有する挟角120°の縁とを具備してなること を特徴とする作業台を提供しようとするものである。 As a means for solving the above-mentioned problems, the present invention has three jacks arranged upright equally on the same circumference with the head above, a frame for integrally connecting the three jacks, and three jacks. Spherical free-rotating bodies attached to the tops of the jacks, a table placed over the respective free-rotating bodies, and the center of the circumference on the back surface of the table when the table is in a horizontal state. The line connecting the center of the free rotating body is divided into two bisectors, and the apex is located on the center side of the table. And a rim having an included angle of 120 ° and having a specified required height.

【0007】[0007]

【作用】[Action]

本考案は上記のように構成されるので次の作用を有する。 Since the present invention is constructed as described above, it has the following effects.

【0008】 即ち、同一円周上に等分に直立配置された3本のジャッキの各頂部に球状の自 由回転体を付設し、その上に載置したテーブルの裏面の上記円周の中心と各自由 回転体中心とを結ぶ線を2等分線としてテーブルの中心側に頂点を有し両斜辺の 内側が自由回転体の周面に内接して堤体状にテーブル裏面に固設された所要高さ を有する挟角120°の縁を備えるため、テーブルはジャッキ上の自由回転体に 点接触で支えられ、かつ、テーブルの面と平行な面内でわずかな力で移動可能で ある。しかも球状の自由回転体に支えられるのであるから移動によってテーブル 面と垂直な方向に上下動を生じることがない。また、三点支持であるから、テー ブルは常に安定する。That is, a spherical free rotating body is attached to each apex of three jacks arranged upright equally on the same circumference, and the center of the circumference of the back surface of the table placed on the spherical free rotating body is attached. The line connecting the center of the free rotating body with the center of the free rotating body is a bisector. With a 120 ° included edge with the required height, the table is supported in point contact with the free rotating body on the jack and can be moved with little force in a plane parallel to the plane of the table. . Moreover, since it is supported by the spherical free rotating body, it does not move up and down in the direction perpendicular to the table surface. Also, the table is always stable because it is supported at three points.

【0009】 また、所要のジャッキを上下操作することにより、テーブルを所望の高さに調 節でき、かつ所望の向きに自由に傾けることができる。その際、三個所のうちの 何れかの縁が必ず、自由回転体にひっかかって滑り止めとなるため、ジャッキか らテーブルが脱落することがなく、かつ、120°をなす縁の挟角が、自由回転 体を挟んでテーブル面に平行な面内での移動を制限するため、テーブル面の不測 の変位が起らない。Further, by operating the required jack up and down, the table can be adjusted to a desired height and can be freely tilted in a desired direction. At that time, any one of the three edges must be caught on the free rotating body to prevent slipping, so the table does not fall off from the jack, and the included angle of the edge of 120 ° is Unexpected displacement of the table surface does not occur because the movement within the plane parallel to the table surface is restricted by sandwiching the free rotating body.

【実施例】【Example】

本考案の一実施例の作業台を図1、図2、図3について説明する。 A workbench according to an embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3.

【0011】 図1は本実施例の作業台10の斜視図、図2はテーブル下面の平面図、図3は 水平時及び傾斜時のテーブルとジャッキ頂部のボールベアリングとの当接部、即 ち、図2のIII −III 矢視相当の支点部の部分断面図である。FIG. 1 is a perspective view of a workbench 10 of the present embodiment, FIG. 2 is a plan view of the lower surface of the table, and FIG. 3 is a contact portion between a table and a ball bearing at the top of the jack when the table is horizontal and inclined. 3 is a partial cross-sectional view of a fulcrum portion corresponding to the line III-III in FIG. 2.

【0012】 これらの図において、3本のジャッキ1は同一円周上に直立して等分に配置さ れ、垂直にフレーム2で連結されている。各ジャッキ1のヘッド1aに自由回転 する支点としてボールベアリング1bを付設し、前記ボールベアリング1b上に テーブル3を乗せ、ボールベアリング1bとテーブル3の滑り止めとして、テー ブル3下面の各ボールベアリング1b位置に、扇状に120°開いた縁4をテー ブル3下面に設けるとともに各縁4の扇状の根元4aをテーブル中心3aに向け てある。In these figures, three jacks 1 are vertically arranged on the same circumference in equal parts and vertically connected by a frame 2. A ball bearing 1b is attached to the head 1a of each jack 1 as a fulcrum for free rotation, and a table 3 is placed on the ball bearing 1b. At the position, a fan-shaped edge 4 opened 120 ° is provided on the lower surface of the table 3, and a fan-shaped root 4a of each edge 4 faces the table center 3a.

【0013】 次に上記構成の作用を(1)〜(5)の項目に分け手順を追って説明する。因 みにこれらの作用を図4に示す。「No 」が以下の項目番号に対応する。Next, the operation of the above configuration will be described by dividing it into items (1) to (5) and following the procedure. By the way, these actions are shown in FIG. "No" corresponds to the following item numbers.

【0014】 (1)テーブル高さ調整;三本のジャッキ1を同時に必要高さに昇降させる。(1) Table height adjustment: The three jacks 1 are simultaneously raised and lowered to a required height.

【0015】 (2)テーブル前方傾動;後方ジャッキ1を持上げる。(2) Tilt forward of table; lift rear jack 1.

【0016】 (3)テーブル後方傾動;前方左右ジャッキ1を持上げる。(3) Tilt rearward of table; lift front left and right jacks 1.

【0017】 (4)テーブル側面傾動;傾動面側の前方ジャッキ1を固定して前方他のジャ ッキ1を持上げ、後方ジャッキ1をやや持上げる。(4) Table side surface tilting: The front jack 1 on the tilting surface side is fixed, the other jacks 1 on the front side are lifted, and the rear jack 1 is lifted slightly.

【0018】 (5)テーブル前方側面傾動;傾動面側の前方ジャッキ1を固定して、前方他 のジャッキ1と後方ジャッキ1を持上げる。(5) Tilting the front side of the table; The front jack 1 on the tilting surface side is fixed, and the other jacks 1 and the rear jack 1 are lifted.

【0019】 以上の通り、本実施例によればジャッキ1昇降により、テーブル3の昇降及び 傾きを所望の通りに行なうことができるという利点がある。即ち、3本のジャッ キ1をどのように昇降させても、重力で必ず最低2カ所はジャッキ1のヘッド1 a上のボールベアリング1bとテーブル3下面の扇状縁4が接触しており、作業 時のテーブル3の前後及び横移動は生じ難い。なおジャッキ1の1本の昇降また はジャッキ1の2本の同時昇降ではボールベアリング1bと縁4は2〜3カ所で 接触しており、テーブル3のガタはより生じ難く、テーブル3の昇降と全面傾動 が可能である。As described above, according to this embodiment, there is an advantage that the lifting and lowering and tilting of the table 3 can be performed as desired by lifting and lowering the jack 1. That is, no matter how the three jacks 1 are moved up and down, the ball bearings 1b on the head 1a of the jack 1 and the fan-shaped edges 4 on the lower surface of the table 3 are always in contact with each other at least at two places due to gravity. It is difficult for the table 3 to move back and forth and laterally. When the jack 1 is raised or lowered or the jack 1 is raised or lowered simultaneously, the ball bearing 1b and the rim 4 are in contact with each other at a few places, and it is more difficult for rattling of the table 3 to occur. Full tilting is possible.

【0020】 なお、自由回転体はボールベアリング1bに限定されるものではない。The free rotating body is not limited to the ball bearing 1b.

【0021】[0021]

【考案の効果】[Effect of device]

本考案は上記のように構成されるので次の効果を有する。 Since the present invention is configured as described above, it has the following effects.

【0022】 即ち、本考案による作業台は、テーブルを自由に高さ調整できるのみならず、 従来の作業台ではできなかった傾動を自由に行なうことができる。That is, in the workbench according to the present invention, not only can the height of the table be freely adjusted, but tilting, which the conventional workbench cannot do, can be performed freely.
