Definitions
- the invention relates to a hand belt grinding machine with the features of the preamble of claim 1.
- a generic hand-held belt grinder with a drive and deflection roller and with an automatic belt run centering is described in EP-PS 7172.
- a sensor with a lever system for pivoting the deflection roller is mounted on the housing of the known hand belt grinding machine. The storage is near the pulley.
- Hand belt sanding machines have the peculiarity that the rotating sanding belt migrates laterally depending on the load and direction.
- the belt run centering is intended to ensure the correct correspondence between the center of the grinding belt and the center of the drive or deflection roller running surface.
- the sensor acts on the pulley via the lever system. This is moved out of its position parallel to the axis of the drive roller in such a way that the belt is again directed into the center of the roller circumference.
- Hand belt grinding machines with the characterizing features of claim 1 have the advantage of a simple, robust and functionally reliable construction with reduced wear both on the centering device and on the grinding belt.
- the service life of the sanding belt is extended considerably.
- the quality of work that can be achieved with hand belt grinding machines is improved.
- Interruptions to work due to the failure of the automatic centering of the strip and a subsequent manual adjustment are no longer necessary.
- the features of the claims following claim 1 serve to advantageously develop the invention.
- Particular advantages of the invention result from the compact, level lever arrangement of the tape centering without mounting on the housing with only a single pivot axis.
- the invention solves the problem of creating a sensitive and robust belt run centering for a hand belt sanding machine with few, easy to manufacture and functionally reliable parts, by which an adjustment after changing the sanding belt is unnecessary.
- FIG. 1 shows a View of a hand-held belt grinder from below
- FIG. 2 shows its side view
- FIG. 3 shows a separate exemplary embodiment of the deflection roller.
- FIG. 1 shows a hand belt grinder 1 with a motor, not shown in detail.
- the hand-held belt grinder 1 has a housing 2 which on the one hand receives an axis 3 with a drive roller 4 and on the other hand a guide plate 5.
- a control plate 6 with a fork-shaped end for receiving an axis 7 of a deflection roller 8 is mounted on this.
- the control plate 6 is pivotably held on the guide plate 5 via a pivot axis 9, or optionally 10, which is designed as a joint.
- the guide plate 5 is guided in guide grooves 11 of the housing 2 transversely to the axes 3, 7.
- the control plate 6 ends on its side facing away from the fork-shaped end in a lever arm 12.
- This carries a thrust part 12 'in the form of a thrust roller, which is directly adjacent to the intended movement path of an outer edge 13 of a drive roller 4 and deflection roller 8 and via a - shown in Figure 2 - grinding plate 19 guided grinding belt 14 is positioned near the drive roller 4.
- the run-on part 12 ' is rotatably mounted and adjustable relative to the outer edge 13 via the eccentric bolt 16.
- a compression spring 17 is supported on one side in the area of the guide grooves 11 on the housing 2 and on the other side in a step-shaped area of the guide plate 5.
- a further compression spring 18 can be supported between the end of the guide plate 5 on the drive roller side and the lever arm 12.
- the deflection roller 8 carries two O-rings 20 on its circumference off-center, on the side of the run-up part 12 '.
- the side view of the hand-held belt grinding machine 1 shown in FIG. 2 illustrates the position of the lever arm 12 with the run-on part 12 'to the sanding belt 14 and the sanding plate 19.
- the position of the guide plate 5 is at about half the height of the drive and deflection rollers 4, 8 and above them the position of the motor shown.
- FIG. 3 shows a guide roller 28 which, on its circumference, instead of the two O-rings 20 according to FIG. 1, laterally carries a bead 40 which is molded into the roller material.
- the motor drives the drive roller 4. This transfers the rotary motion required for the grinding to the sanding belt 14 and thus to the deflection roller 8, 28.
- the hand belt sanding machine 1 With the side of the sanding plate 19, the hand belt sanding machine 1 is placed on a surface to be sanded and held. The abrasive belt 14 sliding over this surface causes the surface to be removed.
- the grinding belt 14 runs crosswise in the viewing direction, for example to the left on the rollers 4, 8 or 28.
- the left outer edge 13 meets the run-up part 12 'of the lever arm 12 and moves it to the left.
- This left movement causes the control plate 6 to move about the pivot axis 9 or 10 in the same way.
- the fork-shaped end of the control plate 6 pivots with the deflection roller 8, 28 as a result of this movement to the right about the pivot axis 9 or 10 8 and 28, the grinding belt 14 is guided against its transverse movement to the right.
- the starting part 12 is relieved.
- the lever arm 12 pivots with the control plate 6 about the pivot axis 9 or 10 to the right and thus the fork-shaped end of the Control plate 6 about the pivot axis 9 or 10 back to the left in the starting position.
- the axes 3, 7 are adjusted so that there is a defined, to the left, slight oversteering tendency of the grinding belt 14, so that the latter constantly oscillates slightly towards and away from the start-up part 12 *.
- This oversteering tendency can be varied by the dimensioning of the additional compression spring 18 or by the arrangement of the O-rings 20 or the bead 40 on the deflection roller 8 or 28 or by the alternative, off-center pivot axis 10. If the transverse movement of the grinding belt 14 is influenced by external influences, e.g. when cross-grinding with the hand belt grinding machine, stronger, the above-described restoring effect is also increased.
- a transverse movement of the grinding belt in the viewing direction to the right is automatically compensated for due to the tendency to oversteer to the left.
- the compression springs 17, 18 are means for tensioning the grinding belt 14, which is necessary for operation, and exert a force on the deflection roller 8 or 28 away from the drive roller 4.
- the eccentric pin 16, with which the run-on part 12 'can be adjusted parallel to the axes 3, 7, allows the grinding belt 14 to be shifted to a right, particularly in the viewing direction, into a changed centering position.
- the sanding belt 14 projects with its outer edge 13 beyond the right outer edge of the hand belt sanding machine or the sanding plate 19. This enables a particularly precise and fine, flush, grinding of stepped surfaces or grooves.
- the closely adjacent position of the run-up part 12 'to the drive roller 4 near the grinding plate 19 results in a particularly quickly responding control mode, because the transverse displacement of the grinding belt 14 only begins in this area. The inertia of the control loop is thus significantly reduced because the transverse displacement already controls itself when the transverse displacement occurs.
