Abstract

The invention relates to a driver plate for clamping a crank shaft, which comprises a lathe main shaft provided with a finial in the center, an upper tilting fillet, a lower tilting fillet, an upper clamping tile and a lower clamping tile, wherein a lug is arranged on the upper tilting fillet; a pin hole is formed in the lug; a lug groove and a pin hole are formed in the outer edge of the end face of the lathe main shaft; the upper tilting fillet and the lower tilting fillet take the finial as the centers, and are mounted on the end face of the lathe main shaft in an up-and-down symmetrical manner; the upper tilting fillet lug is correspondingly mounted in the lug groove of the lathe main shaft, and is connected and fixed through a pin; the upper tilting fillet and the lower tilting fillet are connected through connecting bolts; the upper clamping tile and the lower clamping tile are mounted in the upper tilting fillet and the lower tilting fillet respectively; the large end of the crank shaft is mounted between the upper clamping tile and the lower clamping tile, and the crank shaft can be clamped by tightening the connecting bolts between the upper tilting fillet and the lower tilting fillet; when the lathe main shaft rotates, a feeding device of a lathe can be operated to process a workpiece. The driver plate has a reasonable structure, is convenient to operate, safe and reliable to clamp, and applicable to the assembly of different shaft diameter size, therefore, the driver plate is an ideal driver plate for clamping the crank shaft.

Description

technical field [0001] The invention relates to a clamping device for shaft parts, in particular to a crankshaft clamping dial. Background technique [0002] We know that when processing shaft workpieces on lathes or grinders, the center holes at both ends of the workpiece are mostly used to tighten the top axially. This device is more suitable for small and medium-sized shaft parts. For larger crankshafts, this method not only has poor safety and reliability, but also has a small clamping range, which cannot meet the processing needs of crankshafts with different shaft diameters. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a crankshaft clamping dial with reasonable structure, simple manufacture, convenient operation, safe and reliable clamping, and suitable for assembly of different shaft diameters. [0004] The technical solution adopted by t...
