Follow-up type device for machining shaft diameter of journal part of crankshaft connecting rod

Abstract

The invention discloses a follow-up type device for machining a journal of a crankshaft connecting rod. The follow-up type device for machining the journal of the crankshaft connecting rod comprises a base (1), and is characterized in that a top cover (2) covers a base (1); a universal joint bearing (3) is arranged between the base (1) and the top cover (2) and is connected with an oscillating sleeve (4); the inside of the oscillating sleeve (4) is in threaded connection with a feed screw (5); the tail end of the feed screw (5) is connected with a feeding handle (6); a central rack (7) is arranged at the other end of the oscillating sleeve (4); three clamping jaws (8) are uniformly distributed on the circumference of the central rack (7); each clamping jaw (8) is in threaded connection with the outer wall of the central rack (7); a sliding layer is arranged at an inner tip of each clamping jaw (8); a tool rest (9) is arranged at the end, which is away from the feeding handle (6), of the feed screw (5); and the tool rest (9) is matched with the central rack (7).

Description

technical field [0001] The invention relates to a machining device, in particular to a follow-up type crankshaft connecting rod crank neck part shaft diameter processing device. Background technique [0002] The crankshaft is a commonly used transmission part, and it is one of the most important parts in the engine. Since the crankshaft part and the journal part are not coaxial, when the crankshaft is divided into shaft rotation by the journal part, the crankshaft Some will do circular motion in space. If you want to machine the curved neck part, you need to use special curved neck radius processing equipment (crankshaft grinder), that is to say, you need to purchase a special equipment separately to realize the above operations, which adds additional costs to the enterprise ; At the same time, the traditional crankshaft grinder needs a large radius of gyration, and needs to increase the balance counterweight, which is more cumbersome to operate. If can design a kind of me...
