Flatness measuring device for welding gaskets on device base

The utility model relates to a flatness measuring device for welding gaskets on a device base. The measuring device comprises two brackets and a steel wire rope, wherein each bracket is formed by welding a lower horizontal steel plate, a middle vertical steel plate and an upper horizontal steel plate; the bottom of the middle vertical steel plate is perpendicularly fixed in the middle of the upper surface of the lower horizontal steel plate to form an inversed T-shaped structure; one side of the upper horizontal steel plate is fixed on the middle vertical steel plate, and the upper horizontal steel plate is parallel to the lower horizontal steel plate, so that a clamping groove is formed among the upper horizontal steel plate, the middle vertical steel plate and the lower horizontal steel plate; a first screw hole is formed in the upper horizontal steel plate, a downward first bolt is arranged in the first screw hole, a second screw hole is further formed in the lower horizontal steel plate, an upward second bolt is arranged in the second screw hole, and a through channel is arranged in the middle of the second bolt; a through hole for the penetration of the steel wire rope is formed in the middle vertical steel plate; and one end of the steel wire rope penetrates the through hole in the middle vertical steel plate and the channel on the second bolt and is fixed on the channel. The device has the characteristics of simple structure, convenience of use and high universality.
