The invention relates to a negative pressure suction mechanism and an automobile metal plate repairing device, the negative pressure suction mechanism comprises a first bearing seat and a second bearing seat, and the first bearing seat and the second bearing seat are fixed and distributed in the vertical direction; a suction pipe in sliding fit with the first bearing seat is arranged on the first bearing seat in a penetrating mode in the horizontal direction, a suction cup is installed at one end of the suction pipe, and the other end of the suction pipe communicates with a negative pressure assembly arranged on the second bearing seat through a first communicating pipe; a first piston cavity is formed in the inner side of the first bearing base and communicates with the negative pressure assembly through a second communicating pipe, and a first piston is fixed to the portion, located in the first piston cavity, of the suction pipe. The negative pressure suction mechanism further comprises a locking mechanism which is installed on the first bearing base and used for locking the position of the suction cup, the locking mechanism is connected with a driving mechanism installed on the first bearing base, and the driving mechanism is further connected with the negative pressure assembly.
Description
technical field [0001] The invention relates to the related technical field of automobile sheet metal repair, in particular to a negative pressure suction mechanism and an automobile sheet metal repair device. Background technique [0002] In the process of production and assembly of automobile bodies, the problem of local deformation of sheet metal often occurs. At this time, it is necessary to repair the deformation of sheet metal. At present, when repairing automobile sheet metal, repair tools such as crowbars and ejector rods are mainly used to push back the depressions and flatten the protrusions. However, this type of repairing device and repairing method are prone to problems of uneven application of force and insufficient application of force when repairing automobile sheet metal due to the lack of force-applying guidance and relying entirely on workers to push and pull when applying force. [0003] The existing automobile sheet metal repair device generally include...
