Abstract

The utility model relates to a rotary clamping device used for machining double-eccentric crankshaft. The rotary clamping device is characterized by comprising a bottom plate, a rotary plate, a connecting plate, crankshaft clamping devices, a hydraulic tail frame and a computer numerical-control indexing plate, wherein each of the crankshaft clamping devices comprises a crankshaft front-end clamping head, a crankshaft curved section clamping head, a crankshaft straight-section clamping head and a crankshaft rear-end fixing base; the hydraulic tail frame and the computer numerical-control indexing plate are respectively arranged at the two ends of the bottom plate; the rotary plate is connected and arranged between the hydraulic tail frame and the computer numerical-control indexing plate by the connecting plate; the plurality of the crankshaft clamping devices are arranged on the rotary plate; the crankshaft front-end clamping head and the crankshaft rear-end fixing base are fixed on the rotary plate in a front-rear corresponding manner; the crankshaft curved section clamping head and the crankshaft straight section clamping head are arranged on the rotary plate between the crankshaft front-end clamping head and the crankshaft rear-end fixing base from front to rear in sequence. The rotary clamping device disclosed by the utility model has the advantage of enabling the double-eccentric crankshaft to directly complete rotary machining by one step on a machining center.

Description

A kind of rotating clamp for two eccentric crankshaft processing
Technical field
The utility model relates to a kind of rotating clamp, relates in particular to a kind of rotating clamp for two eccentric crankshaft processing.
Background technology
At present add and adopt man-hour step-by-step process to process at the oilhole for two eccentric crankshafts and oil groove, be that each oilhole needs a bench drill and workman, each oil groove to need a milling machine and a workman, in its process, take resource thus many, and in whole process, need multiple clamping processing, easily cause that processing dimension occurs unfavorable condition and causes scrapping.
Summary of the invention
For above shortcoming, the purpose of this utility model with a kind of rotating clamp for the processing of two eccentric crankshafts is provided, it can make, and two eccentric crankshaft work in-processes are directly disposable in the heart completes rotation processing.
Technology contents of the present utility model is: a kind of rotating clamp for two eccentric crankshaft processing, is characterized in that it comprises base plate, finger plate, connecting plate, bent axle clamping device, hydraulic pressure tailstock and computer numerical controlled index dial; Bent axle clamping device comprises crankshaft front end chuck, bent axle tune chuck, bent axle straight section chuck and crankshaft rear end holder; Hydraulic pressure tailstock and computer numerical controlled index dial are separately positioned on the two ends of base plate, and finger plate is mounted between hydraulic pressure tailstock and computer numerical controlled index dial by connecting plate; Some bent axle clamping devices are arranged on finger plate, before and after crankshaft front end chuck and crankshaft rear end holder, correspondence is fixed on finger plate, and bent axle tune chuck and bent axle straight section chuck front and back are successively set between crankshaft front end chuck and crankshaft rear end holder on finger plate.
The advantage that the utility model compared with prior art had is: can make the rotation of the multiple pairs of eccentric crankshafts and directly disposablely complete processing, and time saving and energy saving, improve operating efficiency, also improve product quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
