Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides an automobile parts assembly tool, which can solve the technical problem in the related technology that manual installation of lower protection consumes a lot of physical strength and time, and is also prone to cause occupational diseases such as lumbar muscle strain to the workers.

[0033] The embodiment of the present application can set up a robotic arm 4 so that the lower guard 8 can be grabbed by the forearm 42 of the robotic arm 4 and placed at a preset installation location during installation. Grabbing by the forearm 42 of the robotic arm 4 can make the transportation process of the lower guard 8 faster, and under the action of the track 1, the connecting drive mechanism 2 can drive the robotic arm 4 to slide along the track 1 through the connecting rod 3. The robotic arm 4 can carry the lower guard 8 in a larger range, thereby increasing the coverage range of the robotic arm, and under the action of the counterweight block 43, the robotic arm can further maintain a balanced state during the movement, thereby solving the technical problem in the related technology that the use of manpower to install the lower guard 8 will not only consume a lot of physical strength and time, but also easily cause occupational diseases such as lumbar muscle strain to the staff.
