Problems solved by technology

The existing crankshaft eccentric tooling can only process crankshaft eccentric throws of one size. If the crankshaft eccentricity changes, it is necessary to process another pair of crankshaft eccentric tooling, which will cause a lot of waste and also Will affect the machining accuracy of the crankshaft
More importantly, when machining crankshafts with different eccentricities, the entire set of crankshaft eccentric tooling needs to be replaced. When the size of the crankshaft flange changes, many parts on the original tooling need to be replaced, which will result in a huge manufacturing cost. cost

Abstract

The invention relates to a crankshaft eccentricity tool. The tool comprises a lathe disc chuck (1), a head axe disk (2), an eccentricity adjusting assembly, a workpiece connecting assembly, an eccentric positioning assembly and a balance plate assembly in a split structure, wherein the head axe disk (2) is fixed on the lathe disc chuck (1); the eccentricity adjusting assembly, the workpiece connecting assembly and the eccentric positioning assembly are connected into a part for adjusting the eccentricity of a crankshaft of the tool through a connecting component, and are fixed on one side of the head axe disk (2); the balance plate assembly is fixed on the other side of the head axe disk (2) through a connecting component. Compared with the prior art, the crankshaft eccentricity tool has the advantages of accuracy in positioning, convenience in assembling and disassembling, convenience and rapidness in replacement, convenience in transformation, convenience and flexibility in overall structure, low manufacturing cost and the convenience in manufacturing by adopting a split structure, positioning through a positioning pin and connecting through a positioning plate and bolts.

Description

technical field [0001] The invention belongs to the technical processing field and relates to a tool, in particular to a crankshaft eccentric tool. Background technique [0002] Crankshaft eccentric tooling is a special tooling used to process crankshaft throws. The existing crankshaft eccentric tooling can only process crankshaft eccentric crank throws of one size. If the crankshaft eccentricity changes, it is necessary to process another pair of crankshaft eccentric tooling, which will cause a lot of waste and also It will affect the machining accuracy of the crankshaft crank. More importantly, when machining crankshafts with different eccentricities, the entire set of crankshaft eccentric tooling needs to be replaced. When the size of the crankshaft flange changes, many parts on the original tooling need to be replaced, which will cause a huge production cost. cost. Contents of the invention [0003] The object of the present invention is to provide a split structure...
