DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring apparatus, and more particularly, to a roller type deburring apparatus which can efficiently remove burrs formed on a peripheral edge of a work in a thickness direction of the peripheral edge. It is about.

[0002]

2. Description of the Related Art When the peripheral edge of a work is formed by turning, burrs that protrude in the thickness direction of the peripheral edge often occur. Therefore, conventionally, it has been common practice to remove burrs manually using a file or to remove burrs by performing abrasive grain processing or barrel processing.

[0003] However, there is a problem that deburring is inefficient due to manual work, and variation easily occurs due to the skill of the operator. In addition, the size and shape of a work to be applied are limited when barrel processing is performed, and when the work is thin, there is a problem that the work is deformed and it is difficult to specify a burr removal range.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a deburring apparatus capable of accurately removing burrs without deforming a work. I have.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a roller in which a circumferential groove into which a peripheral edge of a work is pressed is formed on an outer peripheral surface, and at least one of the work and the roller is the other. And a floating ring loosely fitted and held in the groove. Then, the sum of the outer diameter of the floating ring and the pushing depth of the work was made larger than the outer diameter of the roller, and the radial width of the floating ring was made smaller than the difference between the depth of the groove and the pushing depth of the work. It is characterized by:

[0006]

In the deburring apparatus constructed as described above,
When the periphery of the work is pushed into and held in the groove formed in the roller and at least one of the work and the roller is driven to rotate relative to the other, the periphery of the work is sequentially pushed into the groove of the roller. Therefore, the burrs formed on the peripheral edge of the work are reliably removed by being pushed into the groove and removed.

In addition, the sum of the outer diameter of the floating ring loosely held in the groove and the pushing depth of the work is made larger than the outer diameter of the roller, and the radial width of the floating ring is adjusted to the depth of the groove and the pushing of the work. It is smaller than the difference in depth. For this reason, when the peripheral edge of the work is pushed into the groove, the outer peripheral portion of the floating ring is pushed out to the opposite side to the pushed position of the work.

Therefore, even if burrs dropped from the work enter the grooves, the burrs are automatically pushed out of the grooves by the floating ring, so that the burrs may clog the grooves. Absent. In addition, even when the work is pushed into the groove, a predetermined gap is secured between the bottom surface of the groove and the inner diameter of the floating ring.
The deformation of the work 5 due to the pushing is prevented.

Further, since the burrs can be removed only by pushing the peripheral edge of the work into the groove, even if the work is extremely thin, the burr can be removed without being deformed. Since deburring is performed only at a part, only a necessary part of the burr can be accurately removed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a schematic configuration showing an embodiment of a deburring apparatus according to the present invention, FIG. 2 is a longitudinal sectional view showing an operation state of the deburring apparatus shown in FIG. 1, and FIG. It is A sectional drawing.

In these figures, a groove 4 is formed along the circumferential direction on the outer peripheral surface of a roller 3 which is mounted on a holder 1 with a shaft 2. The groove 4 is formed to have the same width as the thickness of the peripheral edge of the work 5. When at least one of the work 5 and the roller 3 is rotated relative to the other by driving means (not shown) in a state where the periphery of the work 5 is pushed into and held in the groove 4, the periphery of the work 5 is in the groove 4 of the roller 3. A roller-type deburring device is configured so that burrs formed on the peripheral edge of the roller-type deburring device are successively pushed in to be removed.

As described above, the floating ring 6 is loosely fitted and held in the groove 4 which performs the deburring operation. The sum of the outer diameter of the floating ring 6 and the depth to which the work 5 is pushed is made larger than the outer diameter of the roller 3. For this reason, when the peripheral edge of the work 5 is pushed into the groove 4, the floating ring 6 is pressed against the work 6 by the pressing action of the work 5 while maintaining the state in which the floating ring 6 is held in the groove 4. An outer peripheral portion projects from the groove 4.

The width of the floating ring 6 in the radial direction is smaller than the difference between the depth of the groove 4 and the depth to which the work 5 is pushed. Therefore, even when the work 6 is pushed into the groove 4, a predetermined gap is secured between the bottom surface of the groove 4 and the inner diameter of the floating ring 6, so that the deformation of the work 5 due to the pushing is prevented.

In the deburring apparatus constructed as described above, the peripheral edge of the work 5 is pushed into and held in the groove 4 formed in the roller 3, and at least one of the work 5 and the roller 3 is rotated with respect to the other by a driving device (not shown). When driven, the periphery of the work 5 is sequentially pushed into the groove 4 of the roller 3. Therefore, the burrs formed on the peripheral edge of the work 5 are reliably removed by being pushed into the groove 4 and removed.

Here, by making the sum of the outer diameter of the floating ring 6 loosely fitted and held in the groove 4 and the pushing depth of the work 5 larger than the outer diameter of the roller 3, the peripheral edge of the work 5 is pushed into the groove 4. And floating ring 6 is groove 4
The floating ring 6 is pressed to the side opposite to the work 6 by the pressing action of the work 5 while maintaining the state held therein, so that the outer peripheral portion protrudes from the groove 4.
Therefore, even if burrs that have fallen off from the work 5 have entered the grooves 4, these burrs are
As a result, the burrs are automatically extruded from the grooves 4, so that burrs are not clogged in the grooves 4 and a smooth deburring operation can be performed.

Also, since the width of the floating ring 6 in the radial direction is smaller than the difference between the depth of the groove 4 and the pushing depth of the work 5, even when the work 6 is pushed into the groove 4, the bottom surface of the groove 4 is formed. A predetermined gap is secured between the inner ring and the inner diameter of the floating ring 6. Therefore, the work 5 is not deformed due to an excessive force acting on the work 5 when the work 5 is pushed into the groove 4, and the burr can be removed only by pushing the peripheral edge of the work 5 into the groove 4. Even if it is present, burrs are accurately removed without deformation. Since deburring is performed only at the portion of the roller 3 that is pushed into the groove 4, only the necessary portion of the burr can be accurately removed.

FIG. 4 is a longitudinal sectional view of a main part showing a modification of the groove 4. As shown in FIG. In this modification, the inclined guide surface 7 is provided at the opening edge of the groove 4. Therefore, when the guide surface 7 is provided at the opening edge of the groove 4 in this manner, the workability of positioning the work 5 and the groove 4 is improved.

In the embodiment, the present invention constitutes a deburring device for an outer peripheral edge of a hollow ring-shaped wear ring having a U-shaped cross section used for a piston of an engine. The present invention can be applied to a deburring device for a workpiece, or can remove burrs formed on side edges of a plate material.

[0019]

As is apparent from the above description, according to the present invention, at least one of the rollers or the work is driven to rotate relative to the other while the peripheral edge of the work is pushed into and held in the groove provided in the roller. Thus, burrs can be accurately removed without deforming the work. In addition, clogging of the groove due to the removed burrs can be prevented, and since only the necessary portion of the burrs can be removed, the burrs can be efficiently removed.
