Description

Technical Field

[0001] The utility model belongs to the technical field of automobile radar assembly equipment, and in particular relates to an automobile bumper radar bracket welding device. Background Art

[0002] Nowadays, the rear bumper of a car generally needs to be installed with a radar to monitor the reversing distance, etc. To install a radar on the rear bumper of a car, it is usually necessary to first punch the radar holes on both sides, and then weld and install the radar bracket at the punching position. In current production, the punching process and the radar bracket installation process are operated separately, which has low production efficiency. In addition, the radar bracket needs to be welded and installed after the bumper body is injection molded and painted. Employees are required to mask the welding position of the punching edge with tape during injection molding to prevent paint mist from falling on it during subsequent painting, resulting in unstable subsequent welding. However, during subsequent welding operations, the radar bracket welding offset will still occur, resulting in obvious offset of the radar after assembly.

[0003] In the prior art, the patent document with the announcement number CN 216803730 U discloses a bumper radar hole punching and welding machine, including a base, a support top beam is installed on the top of the base, the support top beam is fixed in the bearing frame, and the bottom ends of the bearing frame are fixed on the base; an L-shaped fixing frame is connected to one side of the support top beam, the bottom of the L-shaped fixing frame is fixed on the base, and an adjusting hydraulic cylinder is installed at the end of the L-shaped fixing frame away from the support top beam and the top of the support top beam. The adjusting hydraulic cylinder is vertically arranged downward, and a strip beam is connected to the bottom of the two adjusting hydraulic cylinders, and a linear motor is installed on the upper surface of the strip beam. An L-shaped fixing plate is installed on the top of the linear motor, and one side of the L-shaped fixing plate extends below the strip beam. Although the above scheme solves the problem of continuous operation of the punching process and the radar bracket installation process, its welding installation method is limited, and it is impossible to complete the installation of bumpers or radar brackets with complex structures, and the placement position of the bumper needs to be manually positioned, which is prone to errors, resulting in inaccurate installation position of the radar bracket.
