Description

Multifunctional photoelectric sensor protection device Technical Field The utility model belongs to the technical field of automobile manufacturing, relates to a clamp for protecting a photoelectric sensor in a welding workshop, and particularly relates to a multifunctional photoelectric sensor protecting device. Background In the automobile manufacturing process, a welding workshop is a key link for welding and assembling automobile body parts. The photoelectric sensor is used as an important device in the welding process and used for detecting the position and state of a workpiece, so that the welding precision and the production efficiency are ensured. At present, a flat iron bracket is generally adopted for directly fixing the photoelectric sensor, only a basic fixing function is provided, and the photoelectric sensor is exposed outside. However, this approach has the following problems during specific operations: 1. when the workpiece is manually loaded, the workpiece (such as a metal plate) directly collides with the exposed and protruded photoelectric sensor, so that the shell of the photoelectric sensor is easily broken or the lens is easily worn; 2. The outside of the photoelectric sensor is lack of a buffer design, collision impact force is directly transmitted to the photoelectric sensor, the structure is accelerated to be tired, and multidirectional protection of the photoelectric sensor cannot be realized; 3. when the photoelectric sensor is damaged, the photoelectric sensor cannot be replaced quickly and a protection device is installed, so that the production efficiency is low; 4. The fixed installation mode of the photoelectric sensor cannot adjust the installation angle, and the adaptive working condition is single. In the prior art, the installation of the photoelectric sensor cannot be well protected, and the photoelectric sensor is inconvenient to disassemble and assemble and single in adaptation working condition, so that a photoelectric sensor protection device is needed. Disclosure of utility model Aiming at the problems, the utility model mainly aims to design a multifunctional photoelectric sensor protection device, and solves the problems that the photoelectric sensor is single in adaptation working condition, easy to damage and inconvenient to disassemble and assemble by improving the installation mode and the protection structure of the photoelectric sensor.
