Hanger bracket apparatus

Abstract

The present invention provides a hanger bracket apparatus which can realize the miniaturization of the outer framework and increase working efficiency and an outer framework structure, wherein the hanger bracket (1) can hang and keep a welding portion (31) at a determined height, thereby enabling the welding portion (31) with a heavy weight is easily operated and reducing the load of operators (M). under this condition, a promoting apparatus is used to change the exerted force of a spiral spring, and the hanger bracket apparatus (1) can lift and lower the welding portion (31). When not used the hanger bracket apparatus can be kept upside, and when used for work again the hanger bracket apparatus is reset to the working position, and thereby the increase of the working efficiency and the miniaturization of the outer framework can be realized without enabling the welding portion (31) to be kept towards a side direction.

Description

technical field [0001] The invention relates to a suspension device and an outer frame body structure. In particular, it relates to a suspension device and an outer frame structure capable of reducing the size of the outer frame and improving work efficiency. Background technique [0002] In the assembly line of various structures, operators often use hand-held processing machines to process the processed objects. In this case, if the processing machine is a relatively heavy processing machine such as a spot welding machine or a wrench, the burden on the operator will increase. For this reason, Patent Document 1 discloses a technique in which a spring balancer is hung on the top of an outer frame of an assembly line, and a spot welding machine is suspended by the spring balancer. [0003] According to this technology, since the spot welding machine can be suspended at a specified height position (that is, the position where the weight of the spot welding machine is balance...

AI Technical Summary

Problems solved by technology

[0004] However, in the above technique, since the spot welding machine is suspended from the top, it is necessary to retract the spot welding machine laterally in the horizontal direction and place it on a predetermined mounting table when performing other operations.

Therefore, since the mounting table is formed in the outer frame, there is a problem that the outer frame is enlarged in both the horizontal direction and the vertical direction.

In addition, even if the spot welding machine is moved sideways in the horizontal direction, since the wires and air duct hang down, it becomes difficult to put in / out workpieces such as parts, and the operator needs to make a detour.

Therefore, there is a problem that the number of walks increases and the burden on the operator increases, and there is also a problem that the work efficiency deteriorates.

In addition, when resuming the welding operation, the operator must move to the mounting table to pick up the spot welding machine, so this moving operation also causes a problem that the work efficiency deteriorates.
