Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, the utility model embodiment includes being used for carrying out detail sanding at the uneven wall thickness of blank pipe
Arrangement for grinding, for transfer stock pipe and adjust the buffed surface of blank pipe with coordinate arrangement for grinding polish reconditioning chassis 7；Repair
Mill apparatus includes emery wheel unit 1, unit frame 2, traversing arm 3, and emery wheel unit 1 is connected with unit frame 2, and unit frame 2 is connected to traversing
The front end of arm 3, traversing arm 3 only drives unit frame 2 to do linear extendible motion, and emery wheel unit 1 does arcuate movement with respect to unit frame 2；
The carrying roller 4 for blank pipe to be carried out to radial rotating is provided with reconditioning chassis 7.It is to be ground first in the utility model embodiment
Blank pipe is pushed on reconditioning chassis 7, and then reconditioning chassis 7 runs to the lower section of emery wheel unit 1 and stopped, and both reconditioning chassis 7 was arrived
Up to processing stations, then emery wheel unit 1 is done back and forth by the cooperation of traversing arm 3 and unit frame 2 in the complex surface to be repaired of blank pipe
Reconditioning activity, until reconditioning is completed.The main motor of the emery wheel unit 1 of the present embodiment uses power 7.5KW.Surface stock removal per pass
Secondary >=0.2mm, is controlled according to the bistrique translational speed of air pressure and emery wheel unit 1.Bistrique translational speed is 0.8~10m/
Min, bistrique translational speed frequency conversion is adjustable, the um of the um of surface roughness Ra 25 after reconditioning~12.5.Reconditioning region and non-reconditioning
Region occurs without step-like, and possesses fixed point reconditioning, local reconditioning and full reconditioning function.Swing is rotatably connected on unit frame 2
Arm 5 and retractor device 6, the rotary shaft of the end of swing arm 5, the telescopic end of retractor device 6 with emery wheel unit 1 are hinged, and are stretched
The level height of the set location of compression apparatus 6 is higher than the set location of swing arm 5, and retractor device 6 is implemented using telescopic oil cylinder.When
Traversing arm 3 by unit frame 2 to the dimension linear of reconditioning chassis 7 promote when, the telescopic end of retractor device 6 shortens to lift emery wheel unit
1, emery wheel unit 1 makees lift on arc under the limitation of swing arm 5 and moves to cause the polishing point and emery wheel unit 1 of abrasive machine group 1
The angle of the direction of motion of line and traversing arm 3 of center of rotation be consistently greater than 90 ° and less than 180 °.It is both emery wheel unit 1
Arc reconditioning is carried out from the upper side of blank pipe, if carrying out straight line polishing from vertical direction, the descending amount of emery wheel unit 1 is very
It is rambunctious, easily because stroke enters excessive so as to cause polishing amount excessive, and carry out arc reconditioning from side and work as abrasive machine
When the stroke of group 1 is excessive, emery wheel unit 1 is also to be streaked along certain tangential angle from cladding pipe surface, the polishing amount of this mode
It is extremely limited, and the arc polishing of emery wheel unit 1 is by the parts driving of two linear motions, so traversing arm 3 and stretching
The actual act stroke of the stroke of compression apparatus 6 to emery wheel unit 1 be in fact it is reduced, thus equivalent to be exaggerated control institute
Precision is needed, the accuracy of control is improved.
3rd, according to a kind of floating grinding device of claim 1, it is characterised in that：Reconditioning chassis 7 includes chassis 7, and chassis 7 is set
It is placed on track 8, the bottom of chassis 7 is provided with tugboat 9.Tugboat 9 is connected by lifting motor 10 with chassis 7, lifting motor
10 be servomotor.Drive with the affixed rack of tugboat 9 to adjust the height of chassis 7 by Serve Motor Control gear, so
With regard to distance of the blank pipe with respect to emery wheel unit 1 can be adjusted, when occur polishing it is excessive when, chassis 7 can be declined simultaneously, sand
Lifted on wheel unit 1 to accomplish that the very first time separates, this ensures that the precision of polishing, due to the arcuate lift of emery wheel unit 1
Structure, so the separation of emery wheel unit 1 and blank pipe can be slower than vertical lift mode, so the lift adjustment of chassis 7 is very
It is necessary.
Traversing arm 3 includes traversing motor, traversing gear, traversing rack and transverse arm, and rack is affixed with transverse arm, rack and tooth
The output end of wheel engagement, gear and motor is connected.The speed of the reciprocating linear motion of traversing arm 3 is automatically adjusted by frequency converter.
Two carrying rollers 4 are provided with reconditioning chassis 7, two carrying rollers 4 are rotated backward to constitute between setting, two carrying rollers 4 and used
In the placement portion for placing blank pipe.The mutual carrying roller 4 for rotating backward setting can coordinate in real work carries out blank pipe
Micro-adjustment is will need buffed surface all the time emery wheel unit 1 can be followed to act.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
