Machining tool for eccentric shaft

Abstract

The invention discloses a machining tool for an eccentric shaft. The machining tool comprises a first clamping block and a second clamping block. The first clamping block comprises a pedestal and a clamping block, which are cylinders with the same axle center. The clamping block is arranged on the pedestal. A hole groove is formed in the clamping block. An eccentric distance is formed between the center of the hole groove and the axle center of the clamping block. The second clamping block is shaped like a circular ring. An eccentric distance is formed between centers of outer and inner circles of the second clamping block. The eccentric distance between the center of the hole groove and the axle center of the clamping block is the same as the eccentric distance between the centers of outer and inner circles of the second clamping block. In such a way, the machining tool has the advantages that the eccentric shaft can be quickly and conveniently machined, machining efficiency can be increased, labor cost can be lowered, yield is improved; and the machining tool is suitable for batch production.

Description

technical field [0001] The invention relates to the field of tool fixtures, in particular to a processing tool for an eccentric shaft. Background technique [0002] There are two traditional machining methods for eccentric shafts. One method is to use a coordinate boring machine to drill center holes and eccentric center holes at both ends of the shaft. It is not practical when the eccentricity is small. The accuracy of the center hole and the eccentric center hole can not be adjusted once the position of the center hole and the eccentric center hole is determined; another processing method is to punch the center hole at both ends of the shaft, and use the crankshaft grinder to complete the grinding process. High, but requires a special crankshaft grinder, the cost is high; there is another way to process eccentric workpieces on a three-jaw disc or a four-jaw disc. This method has low accuracy and requires repositioning every time a workpiece is processed, which is inefficie...
