Specific implementation mode
A kind of abrasive belt grinding head is ground limiting device, as shown in Fig. 1,2,3,4,5,6,7,8,9,10, including abrasive belt grinding head 2 and
Rack-mounted motor, the abrasive belt grinding head include driving wheel 3, abrasive band 4 and contact wheel 5, and the contact wheel holds with cylinder
The bead contact of device cylinder 1, the limiting device further include the retainer 8 that a lower end offers symmetrical two centre bore, retainer
One axis 11, axis and the equal clearance fit of two centre bores are installed in two centre bores and left end is by retainer ring spacings.The contact wheel is by rolling
Bearing bearing is mounted on an axle, and the contact wheel is located at retainer median plane, is played support, is compressed abrasive band；The contact
Two eccentric bushings 10 are installed in the left and right sides of wheel, and the eccentric bushing end surface supporting rolling bearing of left and right two axially positions, the eccentric bushing
The radius of upper installation position-limited wheel 9, the position-limited wheel is equal to the sum of radius and abrasive band thickness of the contact wheel.
The limiting device further includes guide rod 7 and tensioning spring 6, and guide rod one end is connect with rack, other end installation is protected
Frame is held, retainer can install contact wheel, the driving wheel installed on contact wheel and motor in guide rod telescopic moving, retainer
It is parallel, grinding belt is loaded onto on driving wheel and contact wheel, guide rod puts on tensioning spring for swelling abrasive band.The effect of guide rod
For the contact wheel of abrasive belt grinding head to be connect with rack, and contact wheel can be made along guide rod telescopic moving（Displacement）；It is tensioned bullet
Spring is act as along the open-top retainer of guide rod, to swelling grinding belt, ensures being normally carried out for grinding.
Cylindrical chamber cylinder by steel plate splicing, roll, be welded, main includes girth joint and along mother in the circumferential direction
Two kinds of weld seams of longitudinal seam in line direction.Fig. 1 is the partial schematic diagram of cylindrical chamber cylinder girth joint.To improve vessel surface quality
Or flaw detection requires, and needs weld reinforcement being removed, and reconditioning is smooth.
It is both provided with threaded hole at the endoporus and outer circle maximum eccentric of two eccentric bushings, it is corresponding with threaded hole on axis
Same busbar on be provided with two jackscrew nests, jackscrew 13 is installed, for fixing eccentric bushing in jackscrew nest.
There are many ways to reconditioning weld seam, Fig. 2 is to carry out the grinding of container girth joint using belt grinding machine to set signal.Abrasive band
Milling drum is mainly made of rack and abrasive belt grinding head, and rack plays support bistrique, with rotary bistrique movement and straight-line feed；Peace
Abrasive belt grinding head on rack transverse arm is grinding execution unit.Common abrasive belt grinding head by motor driving wheel,
By the contact wheel of abrasive band and workpiece compression, the grinding belt on driving wheel and contact wheel, the tensioning spring for being tensioned abrasive band
Equal parts composition.Abrasive band is endless belt-shaped, and outside is covered with the grains of sand, is bonded together by bonding agent and band, is contacted with workpiece, by two
Wheel carries out grinding material removal when driving rotation to workpiece；It is cloth base on the inside of abrasive band, is contacted with two-wheeled.
Common abrasive belt grinding head is not due to having grinding limiting device, it is easy to which weld seam is less than base material or directly will after there is grinding
The case where base material is ground off.
The present invention is as shown in figure 3, can effectively overcome this phenomenon of sbrasive belt grinding.Contact wheel 5 is by rolling bearing branch in Fig. 3
It holds, is mounted on an axle, axis is fitted into retainer transverse holes, and clearance fit, left end is by retainer ring spacing.Contact wheel is located in retainer
Two eccentric bushing end faces of support, compression abrasive band, or so are played by roller bearing axially position in heart face.On eccentric bushing
Position-limited wheel is installed, is supported, can be freely rotated around eccentric bushing by rolling bearing, it is axial to be limited by two shaft block rings.At two
The same position of eccentric bushing（At endoporus and outer circle maximum eccentric）Threaded hole is processed, according to requiring to process on the same busbar of axis
Two jackscrew nests ensure that two eccentric bushings are consistent to the circumference eccentric position of axis, that is, ensure two position-limited wheels and contact wheel after assembly
Circumference eccentric position is consistent.
The four directions of axis left end is moved with spanner, shaft rotation is dynamic, and along axis circumferential variation, position-limited wheel returns the eccentric position of eccentric bushing
Turn center with eccentric bushing around axis circumferential variation.If the radius of contact wheel is R1, abrasive band thickness is C, radius R2=R1+ of position-limited wheel
The eccentricity of C, eccentric bushing are E, if contact wheel compresses abrasive band and contacted with cylinder in certain point, position-limited wheel edge is far from drum surface
Maximum distance is then E, as shaft rotation is dynamic, the eccentric position variation of eccentric bushing, and maximum distance of the position-limited wheel edge far from drum surface
0 is gradually decreased to, axis 11 is rotated further, position-limited wheel is contacted with workpiece, and contact wheel is jacked up, and is detached from drum surface, until abrasive band
It is detached from drum surface maximum distance E.
When being ground to cylinder weld seam, feed motion is made in abrasive band along weld seam, and two position-limited wheels are along weld seam both sides cylinder base material
Surface follows movement, rotation axis, the position of adjustment position-limited wheel, contact wheel relative to drum surface, so that it may to facilitate control to weld
The grinding height relative to base material surface is stitched, and keeps grinding highly consistent, is improved the purpose of weld seam grinding quality.
12 latch segments can lock axis and retainer, ensure the position-limited wheel after adjustment, contact wheel relative to cylinder
Stablize constant in the position on surface.
Illustrate the position of adjustment shell and abrasive belt grinding head by Fig. 2.Abrasive belt grinding head is moved first, makes contact wheel by abrasive band
It is pressed at drum surface no-welding-seam, rotation axis, adjustment position-limited wheel edge is far from drum surface distance：If distance>0, it grinds
Face of weld will be less than base material surface；Distance=0, the face of weld ground will be with base material flush；If position-limited wheel and cylinder
Contact, contact wheel（Abrasive band）It lifts, the face of weld ground will be above base material surface.Its weld seam grinding height can be according to product
It is required that facilitating adjustment.
Adjustment is completed, and is locked axis and retainer with latch segment.
Abrasive belt grinding head is moved to position while welding, shown in Fig. 2, abrasive band center is compressed along Weld pipe mill by contact wheel, two limits
Position wheel is located at weld seam both sides, is in overhead positions.Equipment is started, driving wheel drives contact wheel quick rotation, cylinder by abrasive band
Make slow swivel feeding movement, carries out weld seam grinding.After when cylinder somewhere, weld seam is ground to specified altitude, two position-limited wheels and cylinder
Base material contacts and follows barrel body rotation, abrasive band no longer penetration of a cutting tool to be ground to weld seam.As grinding continues, until by cylinder
Whole weld seam is ground to specified altitude.
Using identical operation principle, workpiece is static, bistrique generates feed motion, can carry out cylinder longitudinal seam polishing
It polishes with plane welded seam.
