Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a welding jig in which a plurality of operating members having fluid actuators such as welding guns and clamp members are attached to a supporting member attached to a jig body. A jig device such as a tool.

(Prior Art) Conventionally, in this type of jig device, in order to supply a fluid such as air to a fluid actuator of an actuating member, a large number of piping members such as an air hose are laid on the jig body, and these piping members are handled. Each is connected to the fluid actuator of the operating member.

(Problems to be Solved by the Invention) In the above, there is a problem that the handling of the piping member becomes complicated, the piping work is troublesome, the manufacturing cost of the jig increases, and the maintainability deteriorates.

An object of the present invention is to provide a jig device that solves the above problems and is inexpensive and has good maintainability.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a support member attached to a jig main body with a plurality of operating members having a fluid actuator such as a welding gun and a clamp member. , A plurality of piping members that supply fluid to the fluid actuators of these actuating members are aligned with each other and are connected to each other through connecting pieces arranged at a plurality of longitudinal positions thereof, thereby connecting these piping members to an aggregate. Is formed, the mounting seats for these actuating members are fixedly mounted on the frame, and the supporting member is constituted by the frame.

(Operation) Each actuating member is attached to each mounting seat of the frame body which is a supporting member, and the fluid actuator of each actuating member is connected to the piping member constituting the frame body. The piping work can be performed easily without having to lay each member on the jig main body for piping, and since the support member and the piping member are integrated, the structure of the jig is simplified.

(Embodiment) With reference to FIG. 1, (1) shows a jig body of a welding jig device, which will be described later in detail as a supporting member to the jig body (1) via a bracket (2). The frame (3) is attached, and a plurality of welding guns (4) operated by an air cylinder (4a) which is a fluid actuator is attached to the frame (3).

The frame body (3) is formed by aligning a plurality of air pipes (5), which are piping members, and connecting them to each other in an aligned state via connecting knitting (6) piped at a plurality of longitudinal positions. This will be described with reference to FIGS. 3 to 5. In the embodiment, the welding guns (4) are divided into two groups having different operation timings.
Two upper and lower air pipes (5) (5) for the group and two upper and lower air pipes (5) for the second group shown by B in the figure.
(5) are aligned in two rows on the left and right, and connecting pieces (6) inserted between the air pipes (5) at a plurality of positions in the longitudinal direction thereof.
Are arranged, and each notch (6a) for positioning formed at the side edge of the connecting piece (6) is engaged with each air pipe (5) and welded, whereby these four air pipes (5) are A frame (3) as an aggregate is formed, and a fixing flange (7) for the brat (2) is formed on the lower surface of the frame (3), and a mounting seat (8) for the welding gun (4) is formed on the upper surface thereof. A plurality of each was fixed.

The fixing flange (7) is to be welded to the connecting piece (6), and the mounting seat (8) is integrally attached to the lower surface thereof to form a spacer (8a) L as shown in FIG. The letter-shaped contact piece (8b) is welded to the plurality of air pipes (5), and the welding gun (4) is bolted to the mounting seat (8) at the support bracket (4b).

Then, locate the air pipes (5) (5) of A in the vicinity of each mounting seat (8) of the welding gun of the first group including the welding gun (4) on the left side in FIG. (9) (9)
Attach the same to the B air pipes (5) and (5) in the vicinity of each mounting seat (8) of the welding gun of the second group including the welding gun (4) on the right side in FIG. The T-shaped branch pipes (9) (9) are attached, and the pair of air ports of the air cylinder (4a) of the welding gun (4) attached to each attachment seat (8) are connected through the connecting pipes (10) (10), respectively. Each said mounting seat (8)
Is connected to the branch pipes (9) (9) in the vicinity of, and one end of these air pipes (5) is pipe-connected to a collecting pipe block (11) having a control valve attached to the jig body (1). With the selective air supply from the collecting block (11) to the air pipes (5) (5) of A, the welding gun (4) of the first group,
By selectively supplying air to the air pipes (5) and (5) of B, the welding guns (4) of the second group are opened and closed respectively.

In the drawing, (12) shows a blind plug provided at the other end of each air pipe (5).

(Effects of the Invention) As described above, according to the present invention, the piping work is facilitated, the manufacturing cost of the jig can be reduced, the structure of the jig is simplified, and the maintainability is improved. .
