Description

Technical Field

[0001] The utility model relates to the technical field of intelligent robot production, in particular to a bracket for an intelligent robot welding fixture. Background Art

[0002] The reason why an intelligent robot is called an intelligent robot is that it has a fairly developed "brain". The central processing unit works in the brain. This computer has a direct connection with the person operating it. The most important thing is that such a computer can perform actions arranged according to the purpose. The production of intelligent robots requires welding fixtures for clamping and fixing, so the welding fixture is supported at the bottom by a bracket.

[0003] Application number: CN202020644303.8; discloses a bracket for an intelligent robot welding fixture, and the key points of its technical solution are: it includes a support plate, a connecting lock, a connecting seat, a base frame, a connecting line and a rotating lifting device, the four corners of the top surface of the support plate are locked and fixed with the connecting lock by bolts, the right end of the back of the support plate is fixed to the connecting seat, the bottom end surface of the support plate is integrally connected to the base frame, the bottom left side of the base frame is connected to the connecting line, and a rotating lifting device is provided in the middle of the bottom end of the base frame. The technical effect of the utility model is: to solve the problem that when it is necessary to use a bracket for an intelligent robot welding fixture, since most of the existing brackets are installed and fixed by bolts or welding, it is easy for them to have different heights and angle distances with external welding equipment during welding, which leads to deviations during robot welding and affects the welding effect. By arranging the rotating lifting device in the middle of the bottom end of the base frame, the rack and the gear can be driven by an electric push rod to engage with each other, so that the gear drives the rotating disk to adjust the rotation angle, and the height is adjusted by the lifting cylinder, so as to realize the rotation and lifting adjustment of the welding fixture bracket, which has strong mobility and is easy to operate.
