Abstract

The utility model relates to a core rod repair welding and regrinding machine which comprises a machine frame and a grinding mechanism. The utility model is characterized in that both sides of the machine frame are provided with guide rails; the upper part of the machine frame is provided with screw nuts, and screw rods are arranged in the screw nuts; the lower ends of the screw rods are connected with an elevating mechanism which is matched with the guide rails; the grinding mechanism is arranged on the elevating mechanism which comprises a motor and an abrasive wheel which is directly arranged on a motor shaft or is arranged on a rotating shaft driven by the motor; the lower part of the machine frame is provided with semicircular arced supporting tiles. The utility model has the advantages that the efficiency of core rod grinding is high, and the precision and the smoothness after grinding can completely satisfy the quality requirements. The utility model is suitable for regrinding the core rod used for rolling a seamless steel tube.

Description

Plug soldering sharpening machine
Technical field
The utility model relates to a kind of plug soldering sharpening machine.
Background technology
The rolling too busy to get away plug of seamless steel pipe, plug in use can be pulled, and pulls the position and must study for a second time courses one has flunked, polish, reach the precision of production requirement after, could continue to use.At present, the processing method to the plug pulled is: plug is pulled the position after soldering, polishes with angle frosted turbine.Because this method is a kind ofly to have the artificial polishing process of abrasive machine in arms by the people fully, so not only grinding efficiency is extremely low, precision and fineness do not reach requirement, and more seriously mill is round, directly influences the quality of production of seamless steel pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of grinding efficiency height, polishing back precision and fineness can satisfy the plug soldering sharpening machine of quality requirement fully in order to overcome above-mentioned the deficiencies in the prior art.
The purpose of this utility model is realized by following mode:
The utility model comprises frame, workpiece polishing mechanism, it is characterized in that: the both sides in frame are provided with guide rail, top in frame is provided with screw, be provided with leading screw in the screw, the lower end of leading screw is connected with the elevating mechanism that cooperates with guide rail, and workpiece polishing mechanism is located on the elevating mechanism, and workpiece polishing mechanism comprises motor, emery wheel, emery wheel is directly installed on the motor shaft or is installed in the rotating shaft by driven by motor, is provided with semicircular arc in the bottom of frame and supports watt.
The utility model has the advantages that: the efficient height of polishing plug, polishing back precision and fineness can satisfy quality requirement fully.
Description of drawings
Fig. 1 is a structural representation one of the present utility model; Fig. 2 is the left view of Fig. 1; Fig. 3 is a structural representation two of the present utility model; Fig. 4 is the left view of Fig. 3.
The specific embodiment
With reference to accompanying drawing, the utility model comprises frame 1, workpiece polishing mechanism 2, both sides in frame 1 are provided with guide rail, be provided with screw 3 on the top of frame 1, be provided with leading screw 4 in the screw 3, the lower end of leading screw 4 is connected with the elevating mechanism 5 that cooperates with guide rail, workpiece polishing mechanism 2 is located on the elevating mechanism 5, workpiece polishing mechanism 2 comprises motor 6, emery wheel 7, emery wheel 7 is directly installed on the motor shaft (as accompanying drawing 3, shown in 4), or be installed in by motor 6 by being contained in the rotating shaft 11 on the bearing block 9 that belt pulley 10 drives (as accompanying drawing 1, shown in 2), be provided with semicircular arc in the bottom of frame 1 and support watts 8.Structure shown in the accompanying drawing 1,2 comes down to consistent with the structure shown in the accompanying drawing 3,4, its difference is that the structure shown in the accompanying drawing 1,2 has increased belt pulley, belt, bearing block and rotating shaft than the structure shown in the accompanying drawing 3,4, cost is slightly high, but in use, because the diameter of bearing block is than little many of the diameter of motor, (whether the diameter that depends on emery wheel the service life of emery wheel in the structure shown in the accompanying drawing 3,4 is greater than the diameter of motor so the service life of emery wheel is long; Whether the diameter that depends on emery wheel in the structure shown in the accompanying drawing 1,2 is greater than the diameter of bearing block).
When practical operation; the internal diameter that should select semicircular arc to support watt is consistent with the external diameter of the plug of wanting reconditioning; the plug long with circumference face of weld 300mm is example; plug is fixed on the stand; 17.5 meters of this plug total lengths; external diameter 158.3mm; circumference soldering face 300mm is long; semicircular arc of the present utility model is supported watt soldering that is placed on plug end in front, adjust the position of elevating mechanism and control processing dimension, open motor then; operator's both hands are caught the handle on the leading screw; come and go rotation around plug, the amplitude of rotation is 1/4 of a circumference, promotes sharpening machine forward along plug when rotating; the length that promotes is the front end that supports watt of semicircular arc and the distance between emery wheel; be generally 120mm, 1/4 wide when first, after the long mill of 120mm is good; machine is return and shut down; after plug rotated 1/4 along clockwise direction, the mill that carries out again second 1/4 was repaiied, and finishes up to whole reconditionings by that analogy.The internal diameter that supports watt when semicircular arc is with the external diameter of the plug of wanting reconditioning when inconsistent, can an internal diameter respectively is installed and want the corresponding to semicircular arc fairlead of external diameter of the plug of reconditioning to solve at the two ends that semicircular arc supports watt.
