The invention discloses a fixing tool for crankshaft milling, and solves the problems of complicated structure and low flexibility of the existing crankshaft fixing tool. The fixing tool for crankshaft milling comprises a base with a mounting opening, a first fixing block, two second fixing blocks, first positioning blocks, second positioning blocks and compressing cylinders; a first fixing grooveis formed in each of the two side walls, which are opposite to each other, of the first fixing block; the first fixing block is positioned in the mounting opening; the two second fixing blocks are respectively positioned on the two sides of the first fixing block; each of the second fixing blocks is provided with a second fixing groove; each first fixing groove and the corresponding second fixinggroove form a fixing hole; a guide groove is formed in each second fixing block; the first positioning blocks are mounted on the base; guide blocks which are matched with the guide grooves are arranged on the side walls of the first positioning block; the second positioning blocks are positioned on the sides, opposite to the first fixing block, of the second fixing blocks; regulating bolts are arranged on the second positioning blocks; the compressing cylinders are mounted on the base; a piston rod of each compressing cylinder is connected with a compressing block; and the compressing blockscan compress the upper ends of the fixing holes. The fixing tool for crankshaft milling is simple in structure, convenient to operate and high in flexibility, and improves the milling efficiency.
Description
technical field [0001] The invention relates to a fixed tool for crankshaft milling. Background technique [0002] The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. The crankshaft is subjected to the joint action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to the bending torsional load. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance. [0003] During the production process of the crankshaft, the front end of the crankshaft needs to be milled, so the crankshaft needs to be fixed by a fixed tool. However, in the prior art, the structure of the fixture for fix...
