Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile accessory assembly, specifically is a kind of automatic assembly device for automobile door sill beam. BACKGROUND

[0002] In the automobile manufacturing industry, the door sill beam, as an important component of the vehicle body structure, its production quality and efficiency are directly related to the safety and manufacturing cost of the whole vehicle. When nut plate welding and subsequent bolt assembly operations need to be performed on the door sill beam, the traditional production process usually relies on manual operation. Specifically, in the step of fixing the nut plate to the door sill beam, the worker needs to first manually complete the positioning and preliminary fixing of the nut plate, and then transfer the assembled component to a special welding station for accurate welding by a skilled welder or automatic welding equipment. After completing the welding process, the next step is the bolt assembly process, which also requires manual intervention to accurately install the bolt of a specific specification onto the welded nut plate. In the entire process, due to multiple manual interventions, not only does it complicate the process, but also reduces the work efficiency. This traditional working mode significantly limits the improvement of production efficiency, especially when large-scale production and rapid delivery requirements need to be met, its limitations are more obvious.

[0060] As Figures 1 to 7 shown, the utility model discloses an automatic assembly device for automobile door sill beam, is used for the welding of door sill beam and nut plate, and is used for assembling bolt on door sill beam, and automatic assembly device includes: welding unit 1;Assembly unit 2 is arranged in the side of welding unit 1, and has assembly station 3 and the assembly part 4 of movable setting, and assembly station 3 is used to provide support to the door sill beam of completing welding, and assembly part 4 is used to assemble bolt on the nut plate on door sill beam;Nut plate feeding unit 5 is arranged in the side of welding unit 1, and is used to provide nut plate to be welded;Bolt feeding unit 6 is arranged in the side of assembly unit 2, and is used to provide bolt to be assembled;Conveying unit 7 is arranged between welding unit 1 and assembly unit 2, and is used to convey door sill beam.

[0061] The assembling device in the scheme carries out the working process of assembling the rocker beam. First, the conveying unit 7 accurately sends the rocker beam to be assembled to the position of the welding unit 1, then the nut plate feeding unit 5 starts, which places the pre-prepared nut plate to the specified position on the rocker beam above the welding unit 1. When the nut plate is correctly placed, the welding unit 1 starts to work and welds the rocker beam and the nut plate. After the welding is completed, the conveying unit 7 works again, which stably moves the rocker beam that has completed the welding process to the assembly station 3. After reaching the assembly station 3, the bolt feeding unit 6 provides the required bolts, and the specially designed assembly part 4 is responsible for accurately installing the bolts into the nut plate on the rocker beam. Finally, the conveying unit 7 sends the rocker beam after all the assembly processes to the preset position, thus the entire assembly work is completed, realizing the automation service from the initial positioning to the final assembly. In the entire assembly process, from the initial positioning of the rocker beam, welding to the final bolt assembly, automation operation is realized without direct human intervention. This not only greatly improves the production efficiency and reduces the labor cost, but also ensures the consistency and reliability of product quality, which is very suitable for large-scale production needs.

[0062] Specifically, the welding unit 1 comprises: a first support seat 8, a first welding part 9 and a second welding part 10 movably arranged on the first support seat 8, the first welding part 9 and the second welding part 10 are oppositely arranged for simultaneously welding the rocker beam; a welding station 11 arranged on the side of the first support seat 8 for providing support for the rocker beam; a first driving part 12 arranged on the first support seat 8, the first welding part 9 is connected to the output end of the first driving part 12, the first driving part 12 is used to drive the first welding part 9 to move in the vertical direction; a second driving part 13 arranged on the second support seat 42 and located below the first driving part 12, the second welding part 10 is connected to the output end of the second driving part 13, the second driving part 13 is used to drive the second welding part 10 to move in the vertical direction, wherein the first driving part 12 and the second driving part 13 can be an oil cylinder, an air cylinder, a motor or an electromagnet.

[0063] In operation, the rocker beam is transported by the transporting unit 7 to the welding station 11 of the welding unit 1, at this time, the first welding member 9 and the second welding member 10 are respectively located on both sides of the rocker beam in the vertical direction, the nut plate feeding unit 5 is started, and the pre-prepared nut plate is placed on the designated position on the rocker beam on the welding unit 1, when the nut plate is correctly placed, the first driving member 12 and the second driving member 13 are started synchronously, driving the first welding member 9 and the second welding member 10 to move to the preset welding position along the vertical direction, then the first welding member 9 and the second welding member 10 simultaneously weld the nut plate on the rocker beam on both sides in the vertical direction; the first welding member 9 and the second welding member 10 can be a laser welding head, a resistance welding gun or other suitable welding equipment, they are symmetrically arranged on both sides of the rocker beam, this design allows simultaneous welding from both sides, ensuring the uniformity and strength of the welding, and also improving the welding efficiency.
