一般に工作機械の安全扉は、機械製造現場でベッド上にテ−ブル、コラム、工作ツ−ル等を組み立てて工作機械を完成する際、安全扉、安全カバ−、その機枠等も工作機械部品の組み立て作業と平行して同時に行われる。別の言い方をすれば、工作機械の製造完成後、安全扉を工作機械に後付けで設置することは行われていない。 In general, when a machine tool is manufactured by assembling a table, a column, a machine tool, etc. on a bed at a machine manufacturing site, the safety door, the safety cover, its machine frame, etc. are also machine tools. It is performed simultaneously with the assembly work of the parts. In other words, a safety door is not retrofitted to the machine tool after the machine tool has been manufactured.

工作機械の製造現場で組み立て製造された工作機械は、製造現場でワ−クをテスト加工し、仕様を満足する性能があることを確認したのち、ワ−クの加工メ−カ−の生産工場内へ輸送、搬入、据え付けされ、そこで、工作機械が正常に稼動するかワ−クをテスト加工し、仕様に合格なら工作機械の検収を終える。安全扉を備え付けた工作機械の出荷は、梱包容積が大きい。また、工作機械の輸送時に安全扉の荷重分の振動が工作機械のベッドやコラム、サドル等の他の部材に影響し、加工メ−カ−の生産工場内に工作機械を搬入、据え付けたのちの工作機械のガタが来ている部分のネジ締め等の再調整作業量も増加する。さらに、工作機械に安全扉が取り付けられているので、再調整作業時に身体を乗り入れる容積も狭く、調整作業がしにくい。本発明は、工作機械の輸送の容積を小さくでき、輸送時のガタを小さくすることができる工作機械への安全扉の設置方法の提供を目的とする。 The machine tool assembled and manufactured at the machine tool manufacturing site is tested at the manufacturing site and confirmed that it has the performance that satisfies the specifications. The machine is transported, loaded, and installed, and the work is tested to see if the machine tool is operating normally. If the machine passes the specifications, the acceptance of the machine tool is finished. Shipments of machine tools equipped with safety doors have a large packing volume. In addition, the vibration of the load of the safety door during transportation of the machine tool affected other parts such as the bed, column, and saddle of the machine tool, and the machine tool was brought into the processing manufacturer's factory and installed. The amount of readjustment work such as screw tightening at the part where the play of the machine tool is coming also increases. Furthermore, since a safety door is attached to the machine tool, the volume into which the body can be placed during readjustment work is narrow, and adjustment work is difficult. It is an object of the present invention to provide a method for installing a safety door on a machine tool that can reduce the volume of transportation of the machine tool and can reduce backlash during transportation.

組み立て製造された工作機械と安全扉のプレファブリック材は、別々に梱包されて加工メ−カ−の工場へ輸送されるので、工作機械の梱包容積は減少される。また、輸送時に安全扉の横揺れや上下振動が工作機械に負荷することがないので、工作機械の輸送時にガタが生じる量は小さい。安全扉は工作機械のベッドに接触してはおらず、ベッドを囲繞するように設置されるので、加工メ−カ−の工場内に工作機械を据え付けた後、検収前に工作機械の点検作業を行う仕事量が少ない。さらに、工作機械と安全扉のプレファブリック材を加工メ−カ−の工場建屋内に搬入後、工作機械のベッドを囲繞するように前記安全扉のプレファブリック材を組み立て、工場の床に安全扉を設置することができる。 The assembled machine tool and safety door prefabricated material are packaged separately and transported to the processing manufacturer's factory, reducing the packaging volume of the machine tool. In addition, since the rolling or vertical vibration of the safety door does not load the machine tool during transportation, the amount of backlash generated during transportation of the machine tool is small. The safety door is not in contact with the bed of the machine tool and is installed so as to surround the bed. After installing the machine tool in the factory of the processing manufacturer, check the machine tool before acceptance. Less work to do. Furthermore, after the machine tool and the prefabricated material for the safety door are brought into the factory building of the processing manufacturer, the prefabricated material for the safety door is assembled so as to surround the bed of the machine tool, and the safety door is placed on the factory floor. Can be installed.

The safety door 10 is assembled into the safety door 10 that surrounds the vicinity of the bed 2 of the machine tool 1 through an assembly process of the next prefabric material.
(1) The window plate 110 is inserted in the left wall panel body 10b in advance.
(2) The left wall panel body 10b or the right wall panel body 10a adjusted in advance so that the lower position of the lifting jack 160 is higher than the lower position of the traveling vehicle 150 travels in the vicinity of the side wall of the bed 2 of the machine tool 1. The vehicle 150 is caused to travel, and the traveling vehicle 150 is stopped at a predetermined position.
(3) The other right wall panel body or left wall panel body that has been adjusted in advance so that the lower position of the lifting jack 160 is higher than the lower position of the traveling vehicle 150 travels in the vicinity of the bed 2 side wall of the machine tool 1. The vehicle 150 is caused to travel, and the traveling vehicle 150 is stopped at a predetermined position.
(4) Lowering the screw rod of the lifting jack 160 raises the left wall panel body 10b and the right wall panel body 10a from the floor surface, and floats the lower part (bottom part) of the traveling vehicle 150 on the floor 30 surface. The bottom of the lifting jack 160 is landed to determine the positions of the left wall panel body 10b and the right wall panel body 10a.
(5) The left wall panel body 10b and the right wall panel body 10a are connected to the two auxiliary rail members 111 and 112 by 1 to 3 reinforcing connection members 100i.
(6) The left wall panel body 10b and the right wall panel body 10a are lowered by raising the screw rods of the lifting jack 160, and the lower part of the traveling vehicle 150 is attached to the floor 30 surface to make the bed 2 of the machine tool. The assembly of the safety door 10 that surrounds is finished.
(7) The handle 113 attached to the front of the window plate 110 is moved in the right direction to pull out the window plate 110 from the left wall panel body 10a and to be positioned in front of the work tool.

なお、安全扉１０の組み立て終了後、ジャッキ１６０は走行車１５０と共に底パネルに取り付けたまま残しておいてもよいし、ジャッキ１６０を係止プレ−ト１４０より取り外してもよい。ジャッキ１６０は、ウオ−ム歯車と台形ネジ軸で構成されるスクリュ−ジャッキが好ましく、株式会社大阪ジャッキ製作所のウオ−ムギヤジャッキＷＪＵ（商品名）、ニュ−フォ−カス社のピックジャッキ（商品名）などが利用できる。また、走行車１５０とジャッキ１６０と係止プレ−ト１４０が一体となったミスミ株式会社が販売する一体型キャスタ＆アジャスタパッドＨＣＦＴ（商品名）を使用してもよい。 After the assembly of the safety door 10, the jack 160 may be left attached to the bottom panel together with the traveling vehicle 150, or the jack 160 may be detached from the locking plate 140. The jack 160 is preferably a screw jack made up of a worm gear and a trapezoidal screw shaft. Etc. are available. Alternatively, an integrated caster and adjuster pad HCFT (trade name) sold by MISUMI Corporation in which the traveling vehicle 150, the jack 160, and the locking plate 140 are integrated may be used.

本発明の安全扉は、工作機械１が組み立て製造された後に、工作機械１の作業テ−ブルおよび工作ツ−ルを搭載しているベッド２を囲繞するように安全扉は後付けで設置されるので、予め安全扉が工作機械のベッドに固定されている従来の工作機械と比較して輸送時のガタの発生が少なく、加工メ−カ−の工場における検収前の機械調整作業量が少なく済む利点を有する。また、安全扉が工作機械のベッドに接触しないでベッドを囲繞するように組立設置されているので、工作機械の温度変化を小さくできるとともに、ワ−ク加工時の安全扉の振動が工作機械に伝達されない故に工作機械の振動も小さいものとなり、ワ−クの加工精度が向上する。 After the machine tool 1 is assembled and manufactured, the safety door according to the present invention is retrofitted so as to surround the work table of the machine tool 1 and the bed 2 on which the machine tool is mounted. Therefore, compared to conventional machine tools in which the safety door is fixed to the machine tool bed in advance, there is less play during transportation, and the amount of machine adjustment work before inspection at the processing manufacturer's factory is reduced. Have advantages. In addition, since the safety door is assembled and installed so as to surround the bed without contacting the bed of the machine tool, the temperature change of the machine tool can be reduced, and the vibration of the safety door during work processing is applied to the machine tool. Since it is not transmitted, the vibration of the machine tool becomes small, and the machining accuracy of the workpiece is improved.
