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

Embodiment Construction
[0024] Below, through Figure 1 to Figure 5 , to describe the embodiment of the present invention. Of course, it goes without saying that the present invention can be easily applied to structures other than those described in the embodiments within a range that does not violate the gist of the present invention.
[0025] figure 1 and figure 2 The welding member holding device 1, which is a fixing jig shown as an example of the present invention, is designed to prevent contact with the surface (upper surface) of the other member 3 when integrally joining metal members such as steel materials by T-joint fillet welding. A device that holds the connected member 2 down or shifts its position. It should be noted that metal members such as steel materials are one member 2 and the other member 3 .
[0026] The welded member holding device 1 is provided with a piston rod 4 for holding one member 2, and a pair of adsorption bodies 5 for adsorbing and holding the welding member hold...

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 an object to be held so as to prevent the member to be held from falling down or being displaced. Background technique [0002] Conventionally, the method of integrating two metal members such as steel plates has been carried out 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 upright with respect to a metal frame placed horizontally, it is necessary to prevent the metal plate from falling down or misaligned during the welding work. As a means of holding the metal plate to be held in a manner that does not cause positional misalignment, in addition to holding by hand, various clampers and locking means using magnetic force have been proposed. For example, Patent Document 1 discloses a technique of holding a pulley with a catch claw p...
