A kind of outer plate punching device for radar sensor of automobile body

Abstract

The invention discloses an external plate punching device for an automobile body radar sensor of an automobile. The external plate punching device comprises an external plate supporting mechanism located at the bottom end, an external plate shrinking assembly is connected to the side face of the external plate supporting mechanism, and an adjustable positioning assembly for clamping an external plate of the sensor tightly is connected to the tail end of the external plate shrinking assembly; a combined punching mechanism is connected to the side face of the external plate supporting mechanismthrough a supporting frame in a hinged mode, and a rotating fine grinding mechanism for grinding a punched hole is mounted inside the external plate supporting mechanism; and the external plate supporting mechanism comprises a pressure-bearing base and two separating blocking seats, a punching chamber is formed between the two separating blocking seats, and tension limiting plates for buffer protection are installed on the surfaces of the separating blocking seats. The acting force is ensured to be even when punching is carried out by the combined punching mechanism, the punching effect is improved, the punching quality is effectively improved by the accurate grinding after punching, the occurrence of punching burrs is avoided, and subsequent processing is facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile production, in particular to an outer plate punching device for a radar sensor of an automobile body. Background technique [0002] The main function of the car body is to protect the driver and form a good aerodynamic environment. A good body can not only bring better performance, but also reflect the personality of the owner. In terms of form, the car body structure is mainly divided into two types: non-load-bearing and load-bearing. [0003] A car with a non-load-bearing body has a rigid frame, also known as a chassis frame. The body of the body is suspended on the frame and connected by elastic elements. The vibration of the frame is transmitted to the body through the elastic elements, and most of the vibration is weakened or eliminated. When a collision occurs, the frame can absorb most of the impact, and it is safe to drive on bad roads. It protects the body at the same time, so the d...

AI Technical Summary

Problems solved by technology

[0009] (1) General punching equipment can only punch a single hole at a time, and after punching, manual adjustment is required to carry out the next punching work, and the punching efficiency is low;

[0010] (2) Moreover, when punching, due to the lack of pre-protection, it is likely to cause local damage to the surface of the outer plate of the sensor, and the general punching method will have certain burrs or unevenness on the surface after punching , affecting the punching quality
