Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology, specifically, it relates to a vertical nailing and error-proof fixing mechanism for an electric gun balance arm. Background Technology

[0002] In the automotive manufacturing industry, nailing is a very common and critical process. As an efficient and precise nailing tool, electric nail guns are widely used in the assembly process of various products. The quality and efficiency of nailing directly affect the overall performance and production progress of the product. Especially in the automotive manufacturing industry, which has extremely high requirements for assembly precision, the accuracy of electric nailing is even more crucial. Even a small nailing deviation may lead to an unstable connection of parts, thereby affecting the safety and reliability of the car.

[0003] In existing electric gun nailing operations at heights, a balance arm is often used to suspend the electric gun to reduce the operator's burden. However, the existing balance arm has a simple structure and only serves as a suspension, making it difficult to ensure the verticality of the nailing direction, which can easily cause problems such as nailing off-center or crooked. At the same time, the installation of the electric gun on the balance arm lacks a fault-prevention mechanism, which poses a risk of unstable installation or incorrect installation, affecting construction efficiency and safety. To address this, we propose a vertical nailing and fault-prevention fixing mechanism for the balance arm of an electric gun. Utility Model Content

A through hole 23 is opened on one side of the L-shaped abutment plate 16. A contact sensor 22 is set near the four corners of the through hole 23. The contact sensor 22 is installed on one side of the L-shaped abutment plate 16. A controller 13 is installed on the front of the first connecting frame 5. An alarm light 12 is installed on the front of the mounting plate 1 near the top.

[0016] Furthermore, four contact sensors 22 are signal-connected to controller 13, and controller 13 is electrically connected to alarm light 12.

[0017] Furthermore, a slide rod 6 is installed on the inner wall of the fixed frame 3, and the slide rod 6 moves through the connecting frame 5. A threaded hole 15 is opened on the fixed cylinder.

[0018] Among them, by setting the slide bar 6, the connecting frame 5 can be limited and supported, ensuring the stability of the connecting frame 5 when it moves.

[0019] Furthermore, a limiting slide plate 24 is installed on the outer wall of the second connecting frame 7, and a limiting slide groove 25 is opened on the inner wall of the first connecting frame 5, and the limiting slide plate 24 and the limiting slide groove 25 are slidably connected.

[0020] By setting the limiting slide plate 24 and the limiting slide groove 25, the connecting frame 2 7 can be limited to ensure the stability of the connecting frame 2 7 moving on the connecting frame 1 5.

[0021] Furthermore, a rotating shaft 27 is installed at the output end of the motor 26. The rotating shaft 27 passes through the front of the connecting frame 2 7 and is rotatably connected to the connecting frame 2 7 through a bearing. The fixing plate 8 is fixedly sleeved on the outer wall of the rotating shaft 27.

[0022] By setting a rotating shaft 27, the motor 26 can drive the fixed plate 8 to rotate through the rotating shaft 27.

[0023] Furthermore, a limiting slider 18 is installed at the top of the inner wall of the connecting groove 17, and a limiting groove 19 is opened at the top of the L-shaped abutment plate 16. The limiting slider 18 is slidably connected to the limiting groove 19. A limiting rod 20 is installed on the inner wall of the limiting groove 19.

[0024] The limiting rod 20 can limit the spring 21 and ensure its stability during compression.

[0025] The implementation principle of a vertical nailing and error-proof fixing mechanism for an electric gun balance arm is as follows: In use, the electric gun is passed through the fixing cylinder 14, and then the electric gun is installed and fixed on the fixing cylinder 14 by passing the set screw through the fixing hole. Then the mechanism is installed to the designated position by the mounting plate 1. Then start the second electric cylinder. The second electric cylinder drives the connecting plate 11 to move downward. The connecting plate 11 drives the second connecting frame 7 to move downward. The second connecting frame 7 drives the fixed plate 8 to move downward through the rotating shaft 27. The fixed plate 8 drives the electric gun to move to the specified height of the nailing position. Then, by starting the electric cylinder 4, the electric cylinder 4 drives the connecting frame 5 to move to the left towards the nailing position. The connecting frame 5 drives the electric gun to move towards the nailing position through the connecting frame 7 and the fixing plate 8. At this time, the fixing plate 8 will first drive the L-shaped abutment 16 to contact the plane of the nailing position through the limit slider 18 and the spring 21, so that the four contact sensors 22 contact the nailing plane at the same time. If the four contact sensors 22 do not simultaneously contact the plane, they will send a signal to the controller 13, which will then control the alarm light 12 to sound an alarm, reminding the electric gun that it is not perpendicular to the nailing plane. At this point, motor 26 can be started, causing motor 26 to drive rotating shaft 27 to rotate. Rotating shaft 27 drives fixed plate 8 to rotate, which in turn drives L-shaped abutment plate 16 to rotate. Adjusting the angle of L-shaped abutment plate 16 ensures that all four contact sensors 22 are in contact with the nailing plane simultaneously, thereby adjusting the angle of the electric gun and ensuring that the electric gun is perpendicular to the nailing plane. Then, the electric gun is started by controller 13, allowing the electric gun to drive the nail vertically into the nailing position. Through the above structure, with L-shaped abutment plate 16 and four contact sensors 22, the L-shaped abutment plate can drive the four contact sensors 22 to contact the nailing plane simultaneously, thereby detecting whether the electric gun is perpendicular to the nailing plane. Then, the alarm light 12 can issue an alarm in advance to remind personnel to correct the position of the electric gun, ensuring the accuracy of the electric gun's vertical nailing position, which is highly practical.
