Fixture

Abstract

Provided is a welding member holding device capable of stably holding a member that is a possible welding target so that the same does not fall or shift position and capable of improving workability and worker safety during welding. A welding member holding device (1), capable of holding one member (2) in direct contact with another member (3) when joining the one member (2) to the other member (3), comprises: a negative pressure generating means (7) for generating negative pressure; an adhering body (5) to adhere to the other member (3) by way of the negative pressure generated by the negative pressure generating means (7); and a piston rod (4) to press the one member (2), which is in direct contact with the other member (3), toward the other member (3) by way of the negative pressure generated by the negative pressure generating means (7). The negative pressure generating means (7) generates the suction of the adhering body (5) and the pressing force of the piston rod (4) by way of negative pressure generated by compressed air being supplied.

Description

Technical field [0001] The present invention relates to a fixing jig capable of stably holding a holding object in a manner that prevents a member as a holding object from falling down or causing positional displacement. Background technique [0002] Conventionally, a method of integrating two metal members such as steel plates has been performed not only in the field of machine tools but also in various technical fields such as the construction field. For example, when performing fillet welding of a T-joint with a long metal plate standing up against a metal frame placed in the horizontal direction, it is necessary to prevent the metal plate from falling down or shifting position during the welding operation. As a means to hold the metal plate to be held in a way that does not cause positional displacement, in addition to holding by hand, various clamps or locking means using magnetic force have also been proposed. For example, Patent Document 1 discloses a technique for holdin...

Problems solved by technology

[0009] Furthermore, in the welding fixture of Patent Document 2, the slider body constituting the welding fixture is operated by hydraulic pressure. Since the welding fixture has oil, there is a problem that, for example, when the welding fixture is used, When the frequency increases, or the filler used to prevent oil leakage deteriorates, oil leakage occurs and the surrounding area is polluted by oil leakage along with the use of the welding installation tool, or the maintenance / inspection work for oil leakage prevention is also required to damage the convenience
