Description

Technical Field

[0001] The utility model relates to the technical field of automobile component processing, in particular to a special welding tool for aluminum alloy automobile anti-collision beams. Background Art

[0002] Anti-collision beams are important safety components installed at the front and rear of a vehicle. They absorb external impact forces during a collision, thereby reducing damage to the vehicle. Due to the need for lightweight vehicles, anti-collision beams have become increasingly common in recent years, often made of aluminum alloy. Anti-collision beams typically consist of a main beam and connecting columns, with the ends of the connecting columns connecting the main beam to the vehicle chassis. Both the main beam and the connecting columns are manufactured from extruded aluminum profiles. The connecting column is then welded to the main beam at one end to complete the anti-collision beam assembly.

[0003] Since the connecting column needs to be assembled with the specific position of the chassis in the subsequent work section, the shape and position accuracy of the welding between the connecting column and the main beam is required to be high, otherwise it will cause problems such as difficulty in assembling the anti-collision beam; in particular, the main beam of the anti-collision beam is usually arc-shaped, and the end of the connecting column is also a matching shape. If the two are not well positioned when in contact, they are prone to slippage and misalignment after pressurization. Therefore, how to accurately and efficiently weld the connecting column to the main beam has become a technical problem that technicians need to consider and solve. Summary of the Invention

[0004] The purpose of the utility model is to provide a special welding tool for aluminum alloy automobile anti-collision beams, which is specially used for clamping and positioning of robot welding of aluminum alloy automobile anti-collision beams, preventing slippage and the like during the welding process of the main beam and the connecting column of the anti-collision beam, and has the advantages of high positioning accuracy and reasonable positioning points.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0006] A special welding tool for aluminum alloy automobile anti-collision beams. A plurality of main beam side clamps are installed on the frame for clamping the main beam side of the anti-collision beam. Columns are respectively provided at both ends of the frame. A connecting column pressing mechanism is provided on the columns. Pads are provided at corresponding positions below the connecting column pressing mechanism.

[0007] The connecting column's downward pressure mechanism includes a three-axis downward pressure cylinder and a pressure head mounted on the end of the cylinder's piston rod. The shape of the pressure head matches the shape of the end of the anti-collision beam connecting column and can limit the horizontal position of the connecting column. The pad below matches the curved surface of the main beam.

[0008] Connecting column side clamps are also located on either side of the upper center portion of the frame to clamp the sides of the connecting column of the anti-collision beam. These clamps consist of a horizontal cylinder and a quick-release clamp connected to the end of the cylinder's piston rod, horizontally pressing the connecting column inward. A corresponding pad is located on the other side of the connecting column.

[0009] The main beam end clamps are respectively provided at both ends of the frame for clamping the two ends of the main beam. The main beam section clamps are used to limit the degree of freedom of the two ends of the main beam, making the main beam more stable when fixed to the frame and reducing vibration during welding.

[0010] The main beam side clamps include a main beam side clamp A, which is arranged in the middle of the main beam, and main beam side clamps B are arranged on both sides of the main beam side clamp A. The main beam side clamps include a rotating cylinder and a clamping head installed on the cylinder piston rod, which is used to preliminarily limit the position of the main beam.

[0011] A main beam side pressure mechanism is also provided in the middle of the frame, and the main beam side pressure mechanism matches the position of the connecting column. The main beam side pressure mechanism mainly applies pressure to the main beam at the position of the connecting column to prevent the main beam from shifting during welding.
