Abstract

PURPOSE:To enable transfer of an object to be welded only by the easy operation and inexpensive hoisting device by forming the mating surface of a door to be provided in the opening of a welding chamber into a sloped surface of which the upper part inclines to a welding room side. CONSTITUTION:The mating surface 13 of a door 14 provided in the opening of a welding chamber 12 mounted on a base 1 is formed into a sloped surface of which the upper part inclines toward the room 12. A vacuum seal 5 is incorporated into either one of the room 12 or the surface 13 of the door 14. Putting in and out of an object 6 to be welded to and from the chamber 12 is accomplished first by moving the door 14 in an arrow D direction and to hold the opening of the chamber 12 open. The 1st welding jig table 7 is moved into the opening of the chamber 12 by using the 2nd and 3rd welding jig tables 8, 9. The object 6 is put in and in this state by using a hoisting device in an arrow E direction, whereby the operation is made easy and a floor space is made needless.

Description

[Detailed description of the invention] This invention relates to an electron beam welding device,
In particular, the present invention relates to a large-sized electron beam welding apparatus that uses equipment other than human power to transfer a workpiece to a welding jig table.

Conventionally, there has been a device of this type as shown in FIG.

In the figure, the pace is attached to the bottom.

The welding room, which is composed of side walls and a ceiling, can be isolated from the outside by a door l provided on one or three sides of the side wall, which can be opened and closed with a hinge or slide type, and has a vertical mating surface 3.
Any mating surface of welding chamber λ or door ? A vacuum seal 5 was incorporated in the welding chamber to maintain a vacuum inside the welding chamber. Inside the welding room, there is a first welding jig table 7 for mounting the workpiece 6, and a third welding jig table g for displacing the first welding jig table 7 in rotation i or up and down. Furthermore, a third welding jig table that displaces these in the horizontal direction is stored, and using these welding jig table functions, it can be installed on the ceiling or outside of the side wall of the welding room. The object to be welded t is placed at the position of the electron beam irradiated from the electron gun lθ.
Welding is performed by aligning the welded parts of the

In the above configuration, the work of attaching and detaching the workpiece 6 to the seventh welding jig table 7 is performed by the other second welding jig table 7.
．． Operate 9 on the third welding jig table to move the workpiece 6 to a position close to the door 1 and stop it.
After opening the door, the transfer device f? for the work to be welded installed outside the welding room λ. Accordingly, the workpiece 6 to be welded is moved in the horizontal direction shown by arrow A, and further moved in the vertical direction shown by arrow B if necessary.

FIG. 2 shows another conventional example, in which objects to be welded i, mi, j, and a third welding jig table are placed in the welding chamber λ. ,g
,? The construction is such that a movable trolley/2 that can carry all of the components and move on rails arranged on the floor of the welding room 20 is housed.

In this configuration, the work of transferring the workpiece 6 to and from the first welding jig table 7 is carried out after opening the door and moving the workpiece 6 to the first welding jig table 7 by moving the workpiece 6 to the first welding jig table 7, and then moving the workpiece 6 to the first welding jig table 7, after opening the door. Connect the rail /'7 provided on lJ and the rail // with a connecting rail /S, and then move the movable trolley 12 along the arrow C.
The object to be welded 6 was transferred to the outside of the welding room λ.

However, in the conventional large-scale electron beam welding equipment shown in Fig. 7 and Fig. 2, the mating surface 3 between the welding chamber and the door is vertical, so that the inside of the welding chamber is It is not possible to transfer the workpiece 6 to a certain first welding jig table 7 from above. In addition, the method k) in Fig. 1 has the drawback that it requires a device to horizontally move the workpiece 6 and is difficult to perform the work. ．． Frame/3. As well as requiring equipment such as rail//, /ri and connecting rail/&.

a. The internal volume of the welding room is 1.

b. A floor base outside the welding room 2 is required.

Control and work time are required to load the C0 mobile cart 12 into the welding room.

There were drawbacks such as.

This invention was made in view of the above circumstances, and it is easy to operate by making the mating surface of the door provided at the opening of the welding chamber an inclined surface with the upper part inclined toward the welding chamber. The structure allows the work to be welded to be transferred using only inexpensive lifting equipment.
The object of the present invention is to provide an electron beam welding device that eliminates the drawbacks of conventional devices.

This invention will be explained below using an embodiment shown in FIGS. 3 and 9. The floor does not need to be installed on the base l.

A mating surface 13 with a door/hook provided at the opening of the welding chamber 12 having side walls and a ceiling is an inclined surface with its upper part inclined toward the welding chamber/2 side. Therefore, the door/4Z also has an inclined mating surface. FIG. 9 shows a state in which the door /lI is moved in the direction of the arrow to open the opening of the welding chamber /2. A vacuum seal j is built into one of the welding chamber /J or the mating surface /3 of the door /4/. In addition, the same reference numerals as in FIG. 1 indicate the same parts, and the explanation will be omitted.

Next, the effects will be described. The work of attaching and detaching the workpiece B to the first welding jig table 7 is performed using the door/lI.
9, move the seventh welding jig table 7 to the opening of the welding chamber 12 using the second and third welding jig table counters. Using a lifting device (not shown), the work to be welded can be taken in and out as shown by arrow E.

Based on the above, compared to conventional equipment, a.
Equipment such as trolleys is not required.

b. Since the work to be welded can be attached and removed only from above, the work can be done easily and in a short time.

There is no need for floor space outside the welding room C1 for transferring objects to be welded.

etc., the effect is great.
