Description

Auxiliary device for mounting fender of electric automobile Technical Field The invention belongs to the technical field of automobile processing, and particularly relates to an auxiliary device for mounting an electric automobile fender. Background A fender is an outer panel of a vehicle body that is mounted around the wheels of the vehicle, and is also called a fender because the shape and position of the part on the old vehicle body are similar to those of a wing. In the mounting process of the automobile fender, bolts are pre-tightened to ensure primary connection stability, then the fender is adjusted by a positioning tool to be perfectly matched with an automobile body, the fender is firmly fixed by a fixing device to prevent deflection in the bolt tightening process, all the bolts are tightened to ensure mounting strength, and finally the fixing device and the positioning tool are disassembled in sequence to complete the whole mounting process. When positioning the fender with the positioning tool, a magnetic attraction fixing manner is generally adopted, however, the magnetic attraction fixing manner may cause weakening or disappearance of the magnetic attraction force in some cases. For example, the presence of other strong magnetic field sources (e.g., large electromagnetic equipment, welders, etc.) at the installation site may interfere with the magnetic field distribution of the magnetically attractable positioning tool, resulting in unstable attraction forces or directional shifts. Specifically, electromagnetic interference may affect the magnetic attraction force when welding operations are performed simultaneously in a vehicle body repair shop. Weakening or disappearance of the magnetic attraction force can cause the positioning tool to be fixed not firmly, and the fender is easy to deviate under the influence of external force, so that inaccurate positioning is finally caused. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide an auxiliary device for mounting an electric automobile fender, so as to solve the technical problems that in a magnetic attraction fixing mode, the magnetic attraction is weakened or vanished, the fixing of a positioning tool is not firm, the fender is easy to deviate under the influence of external force, and finally the positioning is inaccurate. The auxiliary device for mounting the fender of the electric automobile comprises a base rod, wherein a plurality of mounting seats are arranged on the base rod, and the mounting seats are sequentially arranged along the length direction of the base rod; Each mounting seat is provided with a first fixed end and a second fixed end, the first fixed end and the second fixed end are respectively provided with a magnetic suction part and a negative pressure suction part, the magnetic suction parts and the negative pressure suction parts of the first fixed end are used for fixing the automobile body, and the magnetic suction parts and the negative pressure suction parts of the second fixed end are used for fixing the fender; The magnetic attraction parts are in transmission connection with the negative pressure adsorption parts, and in the process that the two negative pressure adsorption parts are used for fixing the fender and the vehicle body respectively, the magnetic attraction parts can be triggered to generate magnetic attraction so that the two magnetic attraction parts are used for carrying out magnetic attraction fixing on the fender and the vehicle body respectively. Compared with the prior art, the invention has the advantages that: (1) According to the auxiliary device for mounting the fender of the electric automobile, provided by the invention, the double fixing modes of negative pressure adsorption fixing and magnetic attraction fixing are adopted, so that the fixing effect is further enhanced compared with a single fixing mode, the stability of mounting the fender is greatly improved, and the problem of displacement of the fender caused by vibration or external force in the mounting process is effectively avoided. For example, the magnetic attachment means may in some cases cause the magnetic attachment force to be weakened or vanished. Weakening or disappearance of the magnetic attraction force can cause the positioning tool to be fixed not firmly, and the fender is easy to deviate under the influence of external force, and finally inaccurate positioning is caused. The auxiliary negative pressure adsorption fixing mode can still maintain good fixing under the condition that the magnetic attraction force weakens or disappears, so that the installation of the fender can be continued to be normally carried out. (2) According to the auxiliary device for mounting the fender of the electric automobile, the negative pressure adsorption part is in transmission connection with the magnetic attraction part, the negative pressure adsorption fixing process is connected with the mag
