Automobile doorsill beam welding clamp

Abstract

The invention discloses an automobile doorsill beam welding clamp which comprises a base, wherein a fixed plate is arranged on the base; six clamping mechanisms are fixedly mounted on the fixed plate; a pressure block used for clamping the doorsill beam, a dowel pin I and a clamping air cylinder used for driving each clamping mechanism pressure arm are arranged on the corresponding clamping mechanism; the fixed plate is provided with an auxiliary positioning device at a position, between the adjacent two clamping mechanisms, close to the middle part; the auxiliary positioning device comprises an L-shaped vertical plate which is fixedly mounted on the fixed plate, wherein the top of one side of the L-shaped vertical plate is fixedly provided with a dowel pin II by virtue of an L-shaped connecting block; the dowel pin II is perpendicular to the horizontal plane; and the dowel pin II and the dowel pins I on the clamping mechanisms positioned at the two sides of the dowel pin are on the same straight line. The automobile doorsill beam welding clamp is high in positioning precision, adopts the clamping air cylinders to drive pressure blocks, and is convenient to operate, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to automobile welding technology, in particular to a welding jig for an automobile door sill beam. Background technique [0002] In the automobile welding line, because the clamping is done on the welding fixture, the fixture plays an important role in the whole welding process. During the clamping process of the traditional clamp structure, the vehicle door sill beam is fixed by the positioning pin, and then pressed by the handle, so that the door sill beam is pressed by the upper and lower pressing blocks, but due to the distance between every two adjacent clamping mechanisms It is either too large or too small. During the positioning operation, due to the excessive spacing, the sill beam is unstable and prone to shaking, resulting in insufficient positioning accuracy, which is not conducive to welding. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a welding jig f...

During the clamping process of the traditional fixture structure, the car door sill beam is fixed by the positioning pin, and then pressed by the handle, so that the door sill beam is pressed by the upper and lower pressing blocks, but due to the distance between every two adjacent clamping mechanisms It is either too large or too small. During the positioning operation, due to the large spacing, the threshold beam is unstable and prone to shaking, resulting in insufficient positioning accuracy, which is not conducive to welding
