Clamping device for pipe beveling machine

Abstract

The invention provides a clamping device for a pipe beveling machine. The clamping device comprises a fixing body, transmission plates, power devices and clamping jaws; a first through hole is formedin the inner edge of the fixing body in the axial direction so as to allow a pipe to penetrate through, and tracks re formed in the radial direction of the fixing body; the transmission plates are arranged on the fixing body and can rotate along the axis of the first through hole; the power devices are connected to the transmission plates so as to enable the transmission plates to rotate; each clamping jaws comprises a feeding part which can slide along the track and a clamping part for clamping the pipe, and the feeding parts and the clamping parts are fixedly connected to each other; further, guide surfaces are formed on ones of the transmission plates and the clamping jaws, and the others are provided with transmission structures which are matched with the guide surfaces and can move relative to the guide surfaces, and the guide surfaces extend towards the axis along the radial direction of the fixing body; and the power devices drive the transmission plates to rotate so as to enable the transmission structures to interact with the guide surfaces, so that the clamping jaws extend and slide along the tracks.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a clamping device for a pipe beveling machine and the pipe beveling machine. Background technique [0002] In the process of pipe prefabrication, an important link is pipe beveling. In order to improve the quality and efficiency of pipe beveling, pipe beveling machines are more commonly used at present. The pipe beveling machine usually clamps the pipe through the motor-controlled clamping device, and then performs beveling on the pipe through the advancing and retreating knife mechanism. However, the pipe beveling machine using the motor-controlled clamping device needs a series of structures that cooperate with the motor, so the overall thickness is generally thick; it is not conducive to transportation management. Moreover, the process of the clamping device of the above-mentioned existing pipe beveling machine is small, and it is not suitable for pipes of various siz...
