Description

Technical Field

[0001] The utility model relates to the technical field of connecting angle plate welding, in particular to a welding and fixing device for a connecting angle plate of a screening device. Background Art

[0002] The connecting angle plate of the screening device is an important component for increasing the connection strength between the main beam of the vibrator and the flange of the heavy screening device, and is usually arranged inside the flange of the main beam of the vibrator; the connecting angle plate has an L-shaped structure and includes two side plates. One side plate is used to connect with the vertical plate of the main beam of the vibrator, and the other side plate is used to connect with the flange, which is equivalent to strengthening the connection strength between the flange and the main beam of the vibrator from the inside of the flange. At the same time, the side plate connected to the flange and the flange are jointly connected to the side plate of the screen box with bolts, further strengthening the connection strength between the main beam of the vibrator and the side plate of the screen box; therefore, the connecting angle plate is an important component for connecting the main beam of the vibrator, the flange and the side plate of the screen box, and the welding quality must be ensured. It is one of the essential parts in the screening device.

[0003] Since one side plate of the connecting angle plate of the screening device needs to be connected to the vertical plate of the main beam of the vibrator, and the other side plate needs to be connected to the flange, in order to match the vertical plate of the main beam and the flange, two different types of steel plates are usually welded together; at present, when welding the connecting angle plate, due to the lack of a welding and fixing tooling, manual assistance is required for welding. One welder is responsible for fixing the angles of the two side plates with both hands, and the other welder first spot-welds the two side plates preliminarily, and then welds from the inside and outside of the 90° angle; the existing welding method not only wastes labor and increases the welding construction cost, but also, during the welding process, due to manual assistance for fixing, it is easy to cause the welding position to be at the best welding angle during the welding process, resulting in uneven weld legs and large welding deformation, which has a certain impact on the welding quality and cannot guarantee the welding quality of the connecting angle plate, and will further affect the connection quality of the main beam of the vibrator, the flange and the side plate of the screen box in the later stage, affecting the use of the vibrating screening device.
