Abstract

The invention discloses a hemming device for a narrow space of an automobile cover, which comprises a base, a jacking mechanism, a positioning and clamping mechanism, and a hemming mechanism. The hemming mechanism includes a limit cylinder bracket, a jacking cylinder, a limit Position cylinder, limit mechanism, telescopic guide column, pre-wrapping cylinder, wrapping cylinder, wrapping lifting seat, position sensor, module mounting plate, wrapping module, pre-packing module, travel switch block, travel switch, travel The switch bracket, the wrapping base; the pre-wrapping cylinder drives the pre-wrapping module forward, the jacking cylinder drives the wrapping seat down, the pre-wrapping module descends, the wrapping seat rises, the pre-wrapping module rises and retreats to complete the pre-wrapping. After the hemming seat descends to a certain height, the hemming oil cylinder drives the hemming module forward, and after the hemming seat drives the hemming module down again, the hemming seat starts to rise. After the hemming action is realized, the hemming module moves backward to complete the hemming process .

Description

technical field [0001] The invention relates to a hemming device and method for a narrow space of an automobile cover, and belongs to the technical field of hemming of an automobile cover. Background technique [0002] The pressing of the inner and outer panels of the automobile cover is called hemming, and the cover includes the door, the engine cover, the back door, the trunk cover, the sunroof and the hubcap. The working principle of cover hemming is to put the outer plate of the cover into the mold cavity, then put the welded inner plate of the cover into the outer plate of the cover, pneumatically position and tighten the inner plate of the cover, and drive the pre-wrapping through the hydraulic cylinder. The mechanism and the wrapping mechanism realize the wrapping of the cover. [0003] For the hemming in a narrow space, it is usually done by manual hemming or using a traditional hemming mechanism. The efficiency of manual hemming is low, and the quality of hemming ...
