Background technology
Requirement according to standard SY/T5561-2008 " friction welding drilling rod " and SY/T5987-94 " drilling rod abroad order goods technical conditions ", tool joint and body are through butt welding, after the final heat treatment of welding zone, the welding zone surface should be smooth, also will carry out nondestructive inspection detects, the fluorescentmagnetic particle(powder) that nondestructive inspection is divided into the drilling rod welding zone again detects and ultrasound examination, before the detection, detector device will be in the enterprising line sensitivity debugging of corresponding contrast standard test block, the surface roughness Ra value of reference block is not more than 1.6 ‰ mm, so require drilling rod welding zone cylinder to detect the surface roughness Ra value at position also within this scope, as being worth greater than this, the testing result of nondestructive inspection is with inaccurate, therefore, in the drilling rod welding zone, outer surface all will carry out surface finish and polishing, so that in the drilling rod welding zone, outer surface reaches the requirement of corresponding roughness.The polishing of welding zone inner surface has had sander in the oil drill rocker industry, i.e. the endoporus sander.The cylindrical polishing machine is also used aborning.Has only the polishing of drilling rod welding zone outer surface, all drilling rod manufacturers of China finish the polishing of welding zone cylindrical with the angle grinding machine with by the angle abrasive disc, its efficient is very low, surface quality, especially surface roundness poor quality, though after the polishing machine polishing, also can reach requirement, increase workload to polishing process virtually.With angle grinding machine polishing welding zone cylindrical, recruitment is many, and the station plane is taken up an area of big, and noise is big, and the dust pollution face is big, also is simultaneously one bottleneck slot operation on the drilling rod production line.
Summary of the invention
The purpose of this invention is to provide a kind ofly can polish at oil drill rocker welding zone outer surface, the grinding efficiency height, fineness is good, polishing rear surface circularity is good, can be a large amount of sand belt of polishing process saving and the oil drill rocker welding zone cylindrical polishing system of time.
The objective of the invention is to realize by following mode:
The present invention includes drilling rod cylindrical welding zone sander and wheel holding mechanism, it is characterized in that: drilling rod cylindrical welding zone sander comprises that a bottom is equipped with the flat bogie of guide wheel, on flat bogie, be provided with column, be connected with the middle rear of a structure-steel framing bottom with hinge on the column top, the place ahead in the structure-steel framing bottom is equipped with abrasive machine, front end at structure-steel framing is equipped with handle, motor is installed on structure-steel framing, the output shaft of motor is connected with the grinding wheel spindle of abrasive machine by transmission device, on column, connect a level board, the buffer spring device is installed on level board, and the top of buffer spring device is connected with the rear of structure-steel framing bottom with hinge; Wheel holding mechanism comprises base, the roller frame that on base, is connected a level with cylinder with guide upright post, one group of pair roller is installed on roller frame, wheel holding mechanism is two groups, be respectively initiatively wheel holding mechanism and passive wheel holding mechanism, initiatively wheel holding mechanism is that a cover Power Drive Unit is installed on roller frame, and the drive end of Power Drive Unit is connected with a roller shaft in the pair roller.
Advantage of the present invention is: can polish at oil drill rocker welding zone outer surface, grinding efficiency height, fineness are good, polishing rear surface circularity is good, can be polishing process saving a large amount of sand belt and time.
