Description

Technical Field

[0001] The utility model belongs to the technical field of automobile radar assembly equipment, and in particular relates to automobile bumper radar hole forming and processing equipment. 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. The radar holes are currently mainly formed by direct injection molding or later punching. The direct injection molding method will form a weld line on the surface of the product, resulting in a poor appearance. For the radar holes on both sides of the bumper, if the angle between the normal direction of the hole and the mold opening direction is too large, it is easy to form burrs, which will require manual grinding later. In addition, the punching method requires additional punching equipment, which takes up space.

[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 arranged vertically 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 to the bottom of the strip beam. Although the above scheme solves the problem of continuous operation of the punching process and the radar bracket installation process, it does not solve the technical problem that the normal angle between the radar holes on both sides of the bumper and the mold opening direction is too large during the punching process, which is easy to form burrs, and manual grinding is required later, and the placement position of the bumper and the installation position of the radar bracket are inaccurate, which is prone to errors.
