Abstract
The utility model belongs to the technical field of steel tube internal grinding machine like machining equipment. In the utility model, a motor is fixedly connected with a clamping seat and a traveling trolley and is connected one end of a spindle through a coupler, the spindle is provided with a ball bearing I and a ball bearing II, a long pipe of which one end is supported on the clamping seat are sleeved on the ball bearing I and the ball bearing II, a positioning sleeve is arranged on the spindle between the ball bearing I and the ball bearing II, the other end of the spindle is connected with a grinding wheel shaft through a connector, the long pipe is connected with a short pipe, one end of the grinding wheel shaft is provided with a ball bearing III and a ball bearing IV, short pipes are sleeved on the ball bearing III and the ball bearing IV and are connected by a bolt I and a bolt II, and the other end of the grinding wheel shaft is provided with a grinding wheel sleeve in which a grinding wheel is arranged, as well as a grinding wheel pressure plate and a nut. In the utility model, the rigidity and bending strength of the long pipe are improved by more than two times, the fault rate is reduced by 80 percent due to fewer driving and connecting parts and large spindle size, the service life of a grinding suspension rod is prolonged by 5 to 10 times, the outage factor is lowered obviously, and the assembly and overhaul are quick and convenient.
Description
Technical field
The utility model belongs to the machining equipment technical field, is specifically related to steel pipe internal grinding machine.
Background technology
High temperature, pressure piping that power plant delivering hot water, steam use are to be made by the alloy pipe (material: P91 or P92) of external import.There is radially defective such as ellipse, axial multi-directional bending in the blank steel pipe of import.After internal diameter, external diameter grinding, can satisfy the instructions for use of power plant delivering hot water, steam.
Before the grinding, can not use the part sawing to fall the blank steel tube end part earlier, the carrying roller of horizontal positioned rotation carries out endoporus processing, i.e. grinding then.Because steel pipe is longer, general length is not more than 13 meters.The emery wheel that the cantilever lever that is installed on internal grinding machine walking carriage, built-in mandrel drive the cantilever lever front end rotates and carries out grinding.Because cantilever lever is long, emery wheel heavier (2, about 40kg), to rotate the alternation dynamic loading that (2950 rev/mins) produce at a high speed bigger for the mandrel emery wheel that drives the cantilever lever front end in addition, often cause mandrel to connect to lose efficacy or the fracture of cantilever lever outer tube and cause in grinding machine can not work.
Summary of the invention
The purpose of this utility model is to provide a kind of can improve the steel pipe internal grinding machine cantilever lever steel pipe internal grinding machine in service life.
The utility model concrete structure as shown in Figure 1, be made up of motor 1, shaft coupling 2, ball bearing I 4, locating sleeve 5, mandrel 6, deck 7, ball bearing II 8, long tube 9, joint 10, bolt I 11, ball bearing III12, ball bearing IV 13, bolt II 14, emery wheel 16, nut 17, emery wheel compressing tablet 18, emery wheel cover 19, short tube 21, grinding wheel spindle 22 and walking carriage 23, wherein motor 1 and deck 7 are affixed with walking carriage 23; Motor 1 is connected with mandrel 6 one ends through shaft coupling 2, and mandrel 6 is provided with ball bearing I 4 and ball bearing II 8, is with the long tube 9 that an end is supported in deck 7 on ball bearing I 4 and the ball bearing II 8; The mandrel 6 of section is provided with locating sleeve 5 between ball bearing I 4 and the ball bearing II8; Mandrel 6 other ends are connected with grinding wheel spindle 22 through joint 10; Long tube 9 is connected with short tube 21 through joint 10; Grinding wheel spindle 22 1 ends are provided with ball bearing III12 and ball bearing IV13, are with short tube 21 on ball bearing III12 and the ball bearing IV13, and are connected with bolt II 14 through bolt I 11; Grinding wheel spindle 22 other ends are established emery wheel cover 19, emery wheel compressing tablet 18 and the nut 17 that emery wheel 16 is housed.
Ball bearing I 4 outer ends are provided with shaft block ring 3.
Ball bearing IV13 outer end is provided with bearing cap 20, and bearing cap 20 is affixed through soket head cap screw 14 and short tube 21.
The utility model by strengthening outer tube diameter and wall thickness and grinding wheel spindle diameter, improves bending strength when structural design; The cantilever lever long tube directly is installed on the walking carriage, can avoid the fracture of original long and short steel pipe and reinforcing sleeve junction; Simplify to reduce transmission connection piece, make its connect reliable more, may produce the trouble point and be reduced to minimum; Accomplish to install, overhaul simple, convenient, fast simultaneously.
The beneficial effects of the utility model are that compared with the prior art the rigidity of long tube and bending strength improve more than 2 times; Because simple in structure, transmission connection piece is few, the mandrel size strengthens, and makes fault rate descend 80%, improves 5～10 times the service life of grinding cantilever lever, significantly reduced outage rate, and the assembling maintenance is quick and easy, also can save a large amount of recondition expenses.
