Abstract

The invention discloses an outer clamp type bevelling machine, which comprises a power mechanism, a driving transmission gear, left and right movable rings, left and right gear rings and left and right fixed rings, wherein the left and right movable rings are respectively and fixedly arranged on the left and right gear rings, a plurality of eccentric shafts are respectively and fixedly arranged on the left and right fixed rings in the circumferential direction, each eccentric shaft comprises a shaft body and a cylindrical bulge part arranged at one end of the shaft body, the axial line of each shaft body and the axial line of the corresponding cylindrical bulge part are parallel but do not coincide, the shaft body of each eccentric shaft is fixedly arranged on the left and right fixed rings, a rolling wheel bearing is arranged on each cylindrical bulge part, a plurality of rolling wheel bearings are movably embedded in grooves of the inner side surfaces of the left and right gear rings, the driving transmission gear is engaged with the left and right gear rings, the power mechanism drives the driving transmission gear to rotate, a knife rest holder is fixedly arranged on the front end surface of the left movable ring or the right movable ring, and the front end surface of the left movable ring or the right movable ring is fixedly provided with a knife impacting mechanism. The outer clamp type bevelling machine has the advantages that the relative rotation can be realized, good coaxiality is also realized, during the cutting, the operation stability is high, the stable and smooth rotation can be realized, the cutting precision is high, and the risk of gear clamping and gear stubbing is also greatly reduced.

Description

technical field [0001] The invention relates to a beveling machine, which relates to an external clamp type beveling machine used for pipeline installation in chemical industry, natural gas, nuclear power, petroleum and other industries. Background technique [0002] In the pipeline installation projects of various industries, the quality of the pipeline is particularly important. The quality assurance of the pipeline installation is mainly the cutting and welding of the pipeline. The cutting is the former. In order to improve the quality of the road, cutting and beveling machines are currently used for cutting pipes, especially thick-walled and large-diameter pipes. On the one hand, the efficiency of the existing equipment is extremely low, and the quality of the nozzle after processing cannot be guaranteed, and the material change of the nozzle caused by high temperature will directly affect the next welding work; Higher and higher, cold cutting of metal pipes has been ge...
