The invention belongs to the field of mechanical grinding, and particularly discloses die drilling equipment for stepped shafts. The die drilling equipment comprises a first lantern ring, wherein a second lantern ring is connected to the first lantern ring in a clamping manner; a plurality of first grooves are formed in the first lantern ring; a plurality of second grooves each of which is fitted with the corresponding first groove are formed in the second lantern ring; a movable slot is formed by each first groove and the corresponding second groove; an adjustment and control device is arranged at the top end of the first lantern ring, and comprises an adjustment and control cylinder; the adjustment and control cylinder comprises an input opening and an output opening; a sealing bolt is in threaded connection to the input opening; a plurality of hydraulic cylinders communicating with each other are arranged in the first lantern ring, and communicate with the adjustment and control cylinder; a piston plate is in sliding connection to each hydraulic cylinder; a piston rod is connected to the bottom of each piston plate; the bottom of each piston rod is located in the corresponding movable slot; a drill bushing is connected to the bottom end of each piston rod; and an elastic piece is connected to the bottom end of each drill bushing. Through the adoption of the scheme of the die drilling equipment disclosed by the invention, the position of each drill bushing can be conveniently adjusted, so that the requirement for drilling different stepped shafts can be met through the equipment.
Description
technical field [0001] The invention belongs to the field of mechanical grinding, in particular to a drilling mold tool for workpieces. Background technique [0002] With the rapid development of my country's machinery industry, the market demand for various types of accessories is increasing, especially shaft accessories. The stepped shaft is widely used in various types of machinery because of its easy disassembly and assembly. The stepped shaft needs to be drilled during the production process, and the accuracy of the drilling will directly affect the subsequent use of the stepped shaft. [0003] The patent document with the publication number CN101966602A discloses a drilling mold device for drilling stepped shaft end holes, including a template, a left jaw, and a right jaw. A number of drill sleeves are fixedly installed, and a number of extended drill sleeves are fixedly installed on the shoulder end of the stepped crankshaft. The lower part of the template is a tubul...
