Description

[Detailed Description of the Invention] The present invention relates to a support device for welding robots and other heavy objects.

Conventionally, in this type of device, a heavy object such as a robot is attached to the lower surface of the machine frame on the upper side using a mounting plate on the upper surface and is removably attached to this with screws or the like. Types that are suspended from the bottom surface are known, but in this case, the heavy object can be freely pulled out from the front working position to the rear shelter position as necessary, in preparation for maintenance work, etc. It is preferable that the work can be easily carried out without using a crane or a forklift. The purpose of the present invention is to obtain a device that meets such requirements, and a heavy object 1 such as a robot is attached to the lower surface of the machine frame 3 on the upper side of the mounting plate 2 on the upper surface of the machine frame. 3
In the machine frame 3 which is removably fixed with screws 4 or the like, the machine frame 3 is formed longitudinally in the front and back direction by the mounting plate 2, and left and right parts 1 are formed on the lower surface of the machine frame 3 and extend to both outside sides of the mounting plate 2. A plurality of pairs of brackets 5, 5 are arranged in parallel at intervals in the front-rear direction, and each pair of brackets 5, 5 is provided with a pair of guide rollers 6, 6 each supporting the mounting plate 2 from the lower surface. It consists of

In the illustrated example, the heavy object 1 is an actuating arm 1b extending laterally from the tip of a support arm 1a that is movable back and forth.
is rotatably provided, and a welding gun 1c is provided on the arm 1b so as to be movable forward and backward along the arm 1b, so that the whole is constructed as a welding robot. The lower surface of the machine frame 3 is provided with front and rear stoppers 7, 7 that come into contact with the mounting plate 2 in the forward and reverse positions, and the bracket 5 in the middle of the side surface is provided with a stopper 7, 7 of the mounting plate 2. In the backward movement position, a stopper pin 8 which engages with the front edge of the stopper pin 8 to prevent the plate 2 from moving forward inadvertently is provided so as to be freely retractable against a spring 10 by means of a lever 9 on the outside of the stopper pin 8. In the advanced position of the plate 2, it engages in a notch 11 in its side surface and acts to more or less roughly position the plate 2 in that position.

To explain its operation, the heavy object 1 normally exists in an advanced working position, and is fixed in this position by a screw 4 in preparation for welding or other work. Next, in order to move the mounting plate backward, the fixation by the screws 4 is first released, so that the mounting plate 2 moves downward to a certain extent and lifts the mounting plate 2 on each pair of guide rollers 6, 6 on the outside of the mounting plate 2. Thus, it is possible to move rearwardly along this, and this can be stopped by the stopper pin 8 in the backward movement position.

In this way, according to the present invention, the heavy object 1 can be fixed at the front working position, and once the fixation is released, the heavy object 1 can be attached to each pair of guides on the lower side on the mounting plate 2 on the upper surface of the heavy object 1. It is placed on the rollers 6, 6 and is movable along the rollers, so that the work of moving it to the rear evacuation position can be easily and easily performed without a crane or forklift. It has the effect that it can.
