Clamping device of linkage type pipe fitting

Abstract

The invention belongs to the technical field of a clamping device and discloses a clamping device of a linkage type pipe fitting. The clamping device comprise an operating platform connected with a mechanical arm, an interlocking bar passes through the inner cavity of the operating platform, both sides of the interlocking bar are connected with gear racks, a pressing rod is arranged in the inner cavity of the interlocking bar, and the pressing rod and the bottom of the inner cavity of the interlocking bar are respectively provided with a buffer spring; a left rotating shaft and a right rotating shaft fixedly pass through the operating platform, the upper key of the left rotating shaft is connected with a left toothed wheel and a left clamping jaw, the left toothed wheel is engaged with the toothed bar on the corresponding side of the interlocking bar, the upper key of the right rotating shaft is connected with a right toothed gear and a right clamping jaw, and the right toothed gear is engaged with the toothed bar on the corresponding side of the interlocking bar; the outsides of the left clamping jaw and the right clamping jaw are respectively fixed with a clamping block, and a clamping wheel fastened with the clamping block is rotationally arranged on the operating platform. The clamping device is simple in structure, the mechanical arm isn't provided with an oil cylinder or an air cylinder and other driving devices, and the mechanical arm directly moves, so that the pipe fitting can be automatically clamped by the clamping device, and the energy is saved.

Description

technical field [0001] The invention belongs to the technical field of clamping devices. Background technique [0002] The pipe fitting clamping device is usually used in the mechanical arm in the existing machining factory. This type of pipe fitting clamping device has a splint with a concave semicircular notch, and the two splints are combined to form a circular arc notch. For accommodating pipe fittings, the driving device of the pipe fitting clamping device can be, for example, an air cylinder or an oil cylinder. The air cylinder or oil cylinder is mounted on a mechanical arm according to regulations and outputs power so that the two splints open or close, so that the pipe fittings can be released or clamped. pipe fittings. [0003] The disadvantage of the above technical solution is that it is necessary to add a clamping drive device to the mechanical arm to provide power for the clamping device, which will undoubtedly increase the weight of the mechanical arm, and the...
