Problems solved by technology

[0002] When processing the holes on the four side strips of a cylindrical product, it is generally processed by drilling machine after scribing or machining by machining center. If the drilling machine is used for processing after scribing, a scribing process needs to be added. After scribing, it is necessary to use a sample punch to punch out the center of the hole. Due to manual errors during scribing and punching, the position deviation is relatively large. The hole is tilted, and the processing cycle of this method is longer; while the processing with a machining center has higher precision, but it needs to occupy the machining center equipment to process a product, and it takes a long time to clamp and disassemble the product. The center cannot process other complex products; in addition, due to the high man-hours of the machining center, the processing cost of the holes on the side strips is relatively high

Abstract

The invention discloses a feeding type cylinder side edge strip wing drilling fixture, and belongs to the field of fixtures. The drilling fixture comprises parts such as a fixture body, a drilling jig plate, a rotation shaft, an adjustable positioning plate, a blanking cap, a pressing disc, a limiting block, a compression screw, a knurled thumb screw, a positioning plug pin a, a positioning plug pin b, quick-changing drilling bushings and a bolt washer assembly. By adopting the drilling fixture, the hole machining precision can be greatly improved, the assembling requirement of a corresponding product is guaranteed, occupation of a machining center can be reduced, the machining cost is reduced, and the working efficiency is improved. Through actual detection, when drilling and reaming machining is conducted on sixteen holes formed in four side edge strip wings of a cylindrical product with the diameter of 400 mm and the length of 500 mm by adopting the drilling fixture, the position degree can meet the requirement of 0.1 mm.
