Foldable positioning plate for reamer

Abstract

The invention relates to a foldable positioning plate for a reamer, and belongs to the technical field of reamer positioning. According to the foldable positioning plate for the reamer, a main plate and an inner plate are connected through a hinge, and the main plate and a lower plate are connected through a hinge. When the positioning plate is unfolded, the main plate and the inner plate are connected through a fixing plate, and the main plate and the lower plate are connected through a fixing plate. When the positioning plate is folded, the inner plate is connected and attached to the main plate through the hinge, and the lower plate is connected and attached to the main plate through the hinge. The lower edge of the inner plate is provided with an arc boundary, a check plate is arranged, a distance is kept between the check plate and the arc boundary of the lower edge of the inner plate, and the boundary of the inner plate is provided with a rib plate. The main plate is provided with an arc positioning boundary, a check plate is arranged, a distance is kept between the check plate and the arc positioning boundary, and a rib plate is arranged on the boundary of the main plate. The inner edge of the lower plate is provided with an arc boundary, a check plate is arranged, a distance is kept between the check plate and the arc boundary of the inner edge of the lower plate, and the boundary of the lower plate is provided with a rib plate. The foldable positioning plate has the advantages that the structure is simple, on-site construction is achieved, disassembly and assembly are convenient, conveying is convenient, and the positioning precision is high.

Description

technical field [0001] The invention belongs to the technical field of reamer positioning, in particular to a foldable positioning plate for a reamer. Background technique [0002] At present, in the construction process of engineering ship machinery, the construction of cutter suction dredger occupies a pivotal position. When mechanical equipment such as reamers are in contact with earthwork, parts such as cutter teeth are severely worn and replaced frequently. These wearing parts are all installed on the mechanical equipment according to the designed spatial position, and the installation positioning accuracy has an important impact on the construction stability and working life of the construction machinery, and has a significant impact on the production efficiency. These easy-to-wear parts are not only worn by earth and rocks, but also bear strong impact loads. If the wear is severe, they need to be returned to the factory for repair or even scrapped directly. The direc...

AI Technical Summary

Problems solved by technology

Manufacturers often provide positioning repair boards for repairing worn parts, but there are the following problems: first, the positioning repair boards are difficult to transport due to their bulkiness and large and irregular area; The positioning accuracy is affected due to deformation caused by external factors such as external factors; thirdly, the positioning repair board takes up more space due to its large area. Unrecoverable deformation, the positioning accuracy decreases, and even the positioning function is gradually lost; Fourth, this positioning repair plate is difficult to maintain. After a long period of use, the positioning repair plate is rusty and corroded very seriously, and its positioning accuracy is gradually reduced. decline
