Problems solved by technology

When the existing tooling is used for clamping and positioning the eccentric shaft, because the shaft sleeve and the bottom plate of the tooling are integrated, a set of tooling can only process one specification of the eccentric shaft. The entire set of tooling including the replacement of the tooling requires heavy workload and low production efficiency; in addition, the existing tooling can only clamp a section of the eccentric shaft, and it is only fixed by bolts, lacking angular positioning, and the eccentric shaft with high precision requirements As far as the shaft is concerned, the lack of necessary angular positioning is prone to clamping out of tolerance, resulting in an increase in the scrap rate of workpieces

Abstract

The invention provides a positioning tool of an eccentric shaft and a machine tool. The positioning tool comprises a chuck assembly, a transmission part eccentrically fixed to the chuck assembly, an angle positioning jacket, a front tip, and a rear tip, the angle positioning jacket is connected with the transmission part and is provided with a positioning hole, the positioning hole is conical, andis used for radially fixingthe eccentric shaft, the front tip is fixedly arranged on the chuck assembly, the rear tip is fixedly arranged on the machine tool, and the front tip and the rear tip are used for abutting against the two axial ends of the eccentric shaft. Through the technical scheme, different specifications of eccentric shafts can be rapidly clamped and positioned, the machining precision of the eccentric shaft can be improved, the scrappage is reduced, the positioning tool is simple in structure, only few parts like a spline positioning sleeve need to be replaced, the replacingwork intensity of the positioning tool of the eccentric shaft can be reduced, and the replacing efficiency of the positioning tool is improved.

Description

technical field [0001] The invention relates to the technical field of eccentric shaft processing, in particular to a positioning tool for an eccentric shaft and a processing machine tool. Background technique [0002] The eccentric shaft of the RV reducer is a key component in the reducer, and its machining accuracy is closely related to the quality and life of the reducer. Considering the dimensional accuracy required by the parts, the eccentric shaft of the RV reducer has very high requirements on the eccentricity of the shaft and the surface roughness, which must be completed by one clamping process. When the existing tooling is used for clamping and positioning the eccentric shaft, because the shaft sleeve and the bottom plate of the tooling are integrated, a set of tooling can only process one specification of the eccentric shaft. The entire set of tooling including the replacement of the tooling requires heavy workload and low production efficiency; in addition, the ...
