Welding wire feeding device

Abstract

The present invention provides a welding wire feeding device that improves the workability of maintenance on the storage area that houses the welding wire feeding mechanism. [Solution] The containment area R1 of this welding wire feeding device 1 is arranged at a predetermined distance from the bottom surface 111 in the direction in which the welding wire 4 is fed, and includes a first wall 112 located on the upstream side in the direction in which the welding wire 4 is fed and a second wall 113 located on the downstream side in the direction in which the welding wire 4 is fed. The containment area R1 includes an opening / closing cover 130 that covers the containment area R1. The opening / closing cover 130 has a rotation support mechanism M1 on the side of the first wall 112, and a locking mechanism M2 on the side of the second wall 113 that selects between a closed state and an open state of the opening / closing cover 130. The rotation support mechanism M1 has an opening / closing central axis a1 extending in a direction intersecting the direction in which the welding wire 4 is fed, and an opening mechanism 138 that applies an opening force to the opening / closing cover 130.

Claims

1. A welding wire feeding device that feeds welding wire to the area to be welded, A housing through which the welding wire can be inserted, The system includes a welding wire feeding mechanism that contacts the welding wire and feeds the welding wire to the welding location, The housing includes a housing area for housing the welding wire feeding mechanism, The aforementioned storage area has a bottom surface, The welding wire feeding mechanism is placed on the bottom surface, The aforementioned containment area is In the direction in which the welding wire is fed, the structure includes a first wall located upstream in the direction in which the welding wire is fed and a second wall located downstream in the direction in which the welding wire is fed, which are arranged at a predetermined distance from the bottom surface. The aforementioned storage area includes an opening and closing cover that covers the storage area. The opening and closing cover has a rotational support mechanism on the side of the first wall, The opening / closing cover has a locking mechanism on the second wall side that allows selection between the closed state and the open state of the opening / closing cover. The rotational support mechanism includes an opening / closing central axis extending in a direction intersecting the direction in which the welding wire is fed, and an opening mechanism that applies an opening force to the opening / closing cover to an open state. The locking mechanism maintains the closed state of the opening / closing cover when the opening / closing cover is in the closed state, in opposition to the opening force applied to the opening / closing cover by the opening mechanism. Welding wire feeding device.

2. The locking mechanism is An operation button provided on the second wall, The locking claw provided on the side of the opening / closing cover and engaging with the operation button is included, The aforementioned operation button is provided so as to be selectable between a locked state, in which the closed state of the opening / closing cover is maintained by maintaining the engagement of the locking claw with the operation button, and an unlocked state, in which the open state of the opening / closing cover is maintained by disengaging the locking claw with the operation button. The welding wire feeding device according to claim 1.

3. The locking mechanism has a safety mechanism between the second wall and the operation button for maintaining the locked state of the operation button. The welding wire feeding device according to claim 2.

4. The inner surface of the opening / closing cover on the side of the housing area is provided with ribs that protrude toward the welding wire feeding mechanism. The welding wire feeding device according to claim 1.
