CN202292181U - Accelerating clamping device for rocker arm machining - Google Patents

The utility model relates to the technical field of a clamping device, in particular to an accelerating clamping device for rocker arm machining. The accelerating clamping device comprises a support which comprises a transverse beam, a hanger I and a hanger II, wherein the hanger I and the hanger II are respectively arranged at the two ends of the transverse beam, an oscillating arm is articulated at the lower end of the hanger I, and a locating shaft is arranged at the end part of the oscillating arm; a cam is articulated at the lower end of the hanger II, a locating groove is arranged on the cam, and the locating shaft and the locating groove are correspondingly arranged; a mandrel is arranged at the bottom of the transverse beam; and an adjustable pressing block is arranged in a corresponding position of the oscillating arm. As the locating shaft on the oscillating arm is closely matched with the locating groove on the cam, the accelerating clamping device can rapidly realize the locking and has high stability. The accelerating clamping device has simple structure, reasonable installation and high production efficiency.

Clamping device is accelerated in a kind of rocking arm processing

Technical field

The utility model relates to the clamping device technical field, and clamping device is accelerated in particularly a kind of rocking arm processing.

Background technology

Each operation of rocking arm processing is a prerequisite to clamp rocking arm all.Existing clamping device generally is made up of mandrel and pressing plate, is positioning reference with the rocking arm inner hole during operation, and rocking arm is inserted in the mandrel, loads onto pressing plate then, uses nut screwing clamping.Existing clamping device is simple in structure, but the clamping time is long, and at the bottom of the operating efficiency, inconvenient operation.
