Sheet metal part edge covering device

Abstract

The invention discloses a sheet metal part edge covering device which comprises a box body, an air cylinder is fixed to the inner wall of the top of the box body, a clamping mechanism is fixed to the bottom of the air cylinder, a first servo motor is fixed to the bottom of the box body, and an output shaft of the first servo motor is fixed to the bottom of the clamping mechanism through a linkage device. The clamping mechanism comprises a fixing plate, a mounting plate, a connecting rod, a strip-shaped gear, a rotating gear, an infrared sensor and a laser displacement sensor, mounting grooves are formed in the two ends of the bottom of the fixing plate, and the inner walls of the mounting grooves are in sliding fit with the mounting plate. By using the air cylinder, the first servo motor and the clamping mechanism and arranging a fixing plate, a mounting plate, a connecting rod, a strip-shaped gear, a rotating gear, an infrared sensor and a laser displacement sensor, a sheet metal part can be clamped and fixed, the edge covering efficiency is prevented from being influenced by shaking, meanwhile, the edge covering position of the sheet metal part can be accurately measured, rapid adjustment is conducted, and the production efficiency is improved. And the edge covering precision and efficiency of the sheet metal part are improved.

Description

technical field [0001] The invention relates to the technical field of hemming devices for sheet metal parts, in particular to a hemming device for sheet metal parts. Background technique [0002] In the automobile manufacturing process, a process such as edge wrapping of the inner and outer panels of the door cover is involved. This process usually uses a stamping edge wrapping die to complete the wrapping process. The stamping edge wrapping die includes an upper die seat and a lower die seat. The base is equipped with a positive pressure knife, and the lower mold base is equipped with a bending punch supporting the workpiece and a standard hemming mechanism with pre-bent inserts. The stamping hemming die uses the standard hemming mechanism to drive the pre-bent inserts to pre-bend the edge of the workpiece The hem is formed, and then the hem is pressed against the hem by the longitudinally moving press knife to complete the hemming of the product. The currently used sheet...

Problems solved by technology

The currently used sheet metal hemming device, when in use, needs to bend the short side first, then take out the sheet metal and adjust the orientation to perform the long side bending, which will lead to a decrease in the hemming efficiency, and the sheet metal When hemming, it is necessary to determine the position of the hemming, which requires personnel to continuously adjust and measure repeatedly, resulting in a decrease in the accuracy and efficiency of the hemming of sheet metal parts
