Description
本發明是有關於一種放電加工機,特別是指一種以複門啟閉的放電加工機液槽。 The invention relates to an electric discharge machine, in particular to an electric discharge machine liquid tank which is opened and closed by a double door.
放電加工機為利用連續送出之銅線、鎢線等細金屬線為電極,在呈拉力的狀態下使其移動,輔以去離子水或其他絕緣加工液為介電質,讓具導電性的被加工物與電極之間產生放電燒蝕現象,形成以放電法高精度的將工件加工成任意輪廓形狀之工具機。為了能將工件沉浸於加工液中,放電加工機需設置一具有側向開口的液槽,及一可開啟及封閉該側向開口的擋門,藉由開啟該擋門,能方便操作者進行上下料的動作。 The electric discharge machine uses a thin metal wire such as a copper wire or a tungsten wire which is continuously fed as an electrode, and moves it under tension, and is supplemented with deionized water or other insulating working fluid as a dielectric to make it electrically conductive. A discharge ablation phenomenon occurs between the workpiece and the electrode, and a machine tool that processes the workpiece into an arbitrary contour shape with high precision by a discharge method is formed. In order to be able to immerse the workpiece in the machining fluid, the electric discharge machine needs to be provided with a liquid groove having a lateral opening, and a door for opening and closing the lateral opening, which can be conveniently operated by the operator by opening the door. The action of loading and unloading.
習知一種開啟擋門的設計,是利用一樞設於該擋門及該液槽之間的樞接組,及一相對該樞接組設置於擋門另一側的扣件組鎖設固定,因此當使用者欲更換工件時,需要先打開該扣件組,再藉由該樞接組向外轉動開啟該擋門。這樣的設計不僅作業所需的淨空間較大,且使用上並不便利。 A design for opening the door is a pivoting group pivoted between the door and the liquid tank, and a fastener group fixed to the other side of the door relative to the pivoting group Therefore, when the user wants to replace the workpiece, the fastener group needs to be opened first, and then the door is opened by the pivoting group. Such a design not only requires a large amount of space for work, but is also inconvenient to use.
為了改善上述之缺點,申請人於中華民國新型 專利第M320450號揭示一門中門的創作:利用在該擋門上另裝設一小水槽門,方便使用者於更換工件時,能僅藉由開啟該小水槽門達到更換目的。惟這樣的設計於更換大型工件時仍需開啟擋門,故無法有效降低作業所需的淨空間。 In order to improve the above shortcomings, the applicant is new in the Republic of China. Patent No. M320450 discloses the creation of a middle door: a small sink door is additionally installed on the door, so that when the user replaces the workpiece, the replacement can be achieved only by opening the small sink door. However, such a design still needs to open the door when replacing a large workpiece, so the net space required for the operation cannot be effectively reduced.
再如中華民國發明專利第I269682號與I337908號所分別揭示的連桿啟閉機構、新型專利第232302號所揭示的螺桿昇降擋門、331207號所揭示的配重輔助開啟、M290787號所揭示的剪型連桿昇降擋門等單一門板的創作,雖皆能以不同的驅動方式昇降該擋門,並藉此降低開啟時所需的淨空間,但下述問題仍然無法改善: For example, the link opening and closing mechanism disclosed in the Republic of China invention patent Nos. I269682 and I337908 respectively, the screw lift door disclosed in the new patent No. 232302, the weight assisted opening disclosed in No. 331207, disclosed in M290787 The creation of a single door panel such as a shear-type connecting rod lifting gate can lift and lower the door with different driving methods, and thereby reduce the net space required for opening, but the following problems cannot be improved:
一、啟閉時間較長:當液槽為了適用於大型工件而需裝配大型擋門時,此時擋門的重量及慣性慣量也將隨之增加,而為了避免對於周邊元件造成的衝擊傷害,擋門需以較低的速度移載,而當移動行程較長時,這將造成啟閉速度較慢的缺點。 First, the opening and closing time is longer: When the liquid tank needs to be equipped with a large door for large workpieces, the weight and inertia of the door will increase accordingly, and in order to avoid impact damage to surrounding components, The door needs to be transferred at a lower speed, and when the movement stroke is long, this will cause a disadvantage of a slower opening and closing speed.
二、機台高度無法降低:由於加工機需於下方預留空間供容置開啟後的擋門,因此,當液槽為了適用於大型工件而具有較高的槽體時,對應容置該擋門的空間也需隨之增加,如此一來,因為機台高度增加將導致重心提高,因而產生結構不穩定及震動的現象,影響加工穩定度。此外,放置工件的床台高度也勢必被提高,徒增使用者上下料的不便。 Second, the height of the machine can not be reduced: because the processing machine needs to reserve space under the space to accommodate the opening of the door, therefore, when the liquid tank has a higher tank for large workpieces, the corresponding gear is accommodated. The space of the door also needs to be increased. As a result, the increase in the height of the machine will result in an increase in the center of gravity, resulting in structural instability and vibration, which affects the processing stability. In addition, the height of the bed on which the workpiece is placed is also bound to be increased, which increases the inconvenience of the user to load and unload.
因此,本發明之目的,即在提供一種門板能快速啟閉,且收疊高度低能降低床台高度,提高加工穩定度及方便更換工件的以複門啟閉的放電加工機液槽。 Therefore, the object of the present invention is to provide an EDM liquid tank which can be quickly opened and closed, and has a low stacking height, can reduce the height of the bed, improve the processing stability, and facilitate the replacement of the workpiece by the door opening and closing.
於是,本發明以複門啟閉的放電加工機液槽,包含一槽體、一複門單元、一驅動單元、一傳動單元,及一密封單元。 Therefore, the electric discharge machine liquid tank of the invention with the double door opening and closing includes a tank body, a multi-door unit, a driving unit, a transmission unit, and a sealing unit.
該槽體圍繞界定出一儲液空間,並包括一具有一開口的前側壁,該開口與該儲液空間相連通。 The trough body defines a liquid storage space and includes a front side wall having an opening that communicates with the liquid storage space.
該複門單元連接設置於該槽體的前側壁,並包括相疊的一下門組合,及一上門組合,該複門單元能相對於該槽體,在一封閉位置及一開啟位置之間昇降移動,在該封閉位置時,該上、下門組合封閉該開口,且該上門組合高於該下門組合,在該開啟位置時,該上、下門組合遠離該開口,且使該開口開放。 The multi-door unit is connected to the front side wall of the trough body, and comprises a stack of overlapping door assemblies, and a door assembly. The door unit can be lifted and lowered between a closed position and an open position relative to the trough body. Moving, in the closed position, the upper and lower door assemblies close the opening, and the upper door combination is higher than the lower door combination, in the open position, the upper and lower door assemblies are away from the opening, and the opening is opened .
該驅動單元連接設置於該槽體,並包括一能驅動該複門單元的驅動件。 The driving unit is connected to the tank body and includes a driving member capable of driving the door unit.
該傳動單元連接設置於該複門單元及該驅動單元之間,且能藉由該驅動單元的驅動件,使該複門單元於該開啟位置及該封閉位置之間移動。 The transmission unit is disposed between the multiple door unit and the driving unit, and the moving door unit is movable between the open position and the closed position by the driving component of the driving unit.
該密封單元位於該槽體的前側壁與該複門單元之間。 The sealing unit is located between the front side wall of the trough and the multiple door unit.
本發明之功效在於藉由該複門單元的上、下門組合除了能縮短昇降時所需的時間,更能利用彼此疊合的特點,有效減少收疊時所需空間,進而有效降低床台高度, 達到提高加工穩定度及方便更換工件之優點。 The utility model has the advantages that the upper and lower door combinations of the double door unit can reduce the time required for lifting and lowering, and can utilize the overlapping features to effectively reduce the space required for the stacking, thereby effectively reducing the bed table. height, Achieve the advantages of improved processing stability and easy replacement of workpieces.
