Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring device suitable for removing burrs from ring-shaped mechanical parts, and more particularly, to easily and accurately remove burrs generated on ring-shaped parts by machining. The present invention relates to a deburring device that can be removed.

[0002]

2. Description of the Related Art In order to remove burrs generated in ring-shaped parts, conventionally, the parts are mounted on a workbench, and then a deburring brush that is rotationally driven by an air motor or the like is mounted on the deburring surface of the parts. There was often manual work of moving along.

Therefore, a skilled technique is required to surely remove burrs while avoiding damage to the parts by the brush, but any expert can scatter burrs on a large number of parts in a short time. Since it is difficult to remove into a non-homogeneous state, there has been a demand for more efficient deburring work.

[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 device having a simple structure capable of easily and accurately removing burrs generated in a ring-shaped component. I am trying.

[0005]

In order to solve the above-mentioned problems, the present invention provides a rotary base for holding a ring-shaped component so that it can be rotated and detachably held with the center of the component as the center of rotation. A deburring brush is provided which is pressed against the deburring surface and is driven to rotate in the rotational direction of the component. A timer for presetting the driving time of the deburring brush and brush moving means for retracting the brush to a position separated from the component when the time set in the timer has elapsed from the start of the brush are provided. Is characterized by.

[0006]

In the deburring device for a ring-shaped component constructed as described above, when the timer is started with the ring-shaped component mounted on the rotary table, the deburring brush is held in pressure contact with the deburring surface of the component. At the same time, the deburring brush is driven to rotate. When the deburring brush is driven to rotate in this way, the deburring is removed by the frictional force between the brush and the deburring brush, and the part rotates integrally with the turntable. Brush moves relatively.

When the time set by the timer has elapsed, the deburring brush is stopped and the brush moving means is operated to retract the deburring brush to a position separated from the component.
Therefore, after the brush retreats in this way, remove the parts from the turntable and attach new parts to the turntable.
Similarly, by activating the timer and repeating deburring of components, it is possible to remove burrs from a large number of components in a uniform state without variation in a short time. It should be noted that the timer setting time may be set appropriately according to the size of the parts and the coupling strength of the burrs, etc. It is also possible to automate the attachment / detachment of the parts and the activation of the timer to perform a fully automatic deburring operation. .

[0008]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an external perspective view showing an embodiment of a deburring apparatus according to the present invention, in which a rotary table 2 is attached to the upper surface of a plate-shaped base table 1. The rotary table 2 is a ring-shaped component. 3 is rotated and removably held around the center of the component 3, and the component 3 is attached to the turntable 2 with the deburring surface (burr generation surface) 4 facing upward.

A column 5 is erected on the upper surface of the base 1 on the side of the rotary table 2, and an air motor 8 is attached to the tip of an arm 6 whose base end is rotatably attached to the column 5 via a bracket 7. Is attached. And the air motor 8
When the air motor 8 is operated by holding the deburring brush 9 attached to the output shaft (not shown) of the deburring brush 9 against the deburring surface 4 of the component 3 on the turntable 2, the deburring brush 9 rotates in the direction of rotation of the component 3. It is designed to be driven to rotate. The deburring brush 9 is composed of, for example, a wire brush or the like, and removes the burrs generated on the component 3 by the frictional force caused by the contact with the component 3.

On the other hand, a timer 11 is provided in the middle of an air pipe 10 from a factory air (not shown) to the air motor 8.
Is attached to the base 1, so that the drive time of the deburring brush 9 can be set in advance. Reference numeral 12 is an adjustment dial for arbitrarily setting the operating time of the air motor 8, and 13 is a start button for the timer 11.

Further, the base 14 and the lever 14 of the bracket 7
The tip of the rod 15 fixed to the above is connected via an air cylinder 16 which functions as a brush moving means. Then, the timer 11 and the air cylinder 16 are connected through an air pipe (not shown) to switch and supply air to the air motor 8 and the air cylinder 16.

That is, when the timer 11 is activated to operate the air motor 8, the air supply to the air cylinder 16 is interrupted and the brush 9 is applied by the weight of the air motor 8 or the like.
Is held in pressure contact with the deburring surface 4 of the component 3. However,
When the time set in the timer 11 elapses and the air motor 8 is stopped, air is supplied to the air cylinder 16 and the air cylinder 16 extends, so that the bracket 7 and the air motor 8 move in the counterclockwise direction in the figure. Since the brush 9 is lifted and rotated, the brush 9 is retreated to a position separated from the component 3. Reference numeral 17 is a brush cover.

In the deburring device for a ring-shaped component constructed as described above, when the start button 13 is pressed down while the ring-shaped component 3 is attached to the rotary table 2, the supply of air to the air cylinder 16 is interrupted. As well as
Air is supplied to the air motor 8. Then, since the air motor 8 rotates clockwise in the drawing around the base end of the arm 6 and descends to the operating position shown in the drawing, the brush 9 is moved by the brush 9 by the self-weight of the air motor 8 or the like. Is pressed and held, and the deburring brush 9 is rotationally driven.

When the deburring brush 9 is rotationally driven in this manner, the burr is removed by the frictional force with the brush 9. Also, due to the frictional force between the component 3 and the brush 9, the turntable 2
At the same time, as the component 3 rotates, the brush 9 relatively moves along the deburring surface 4 of the component 3, so that the burr removal position by the brush 9 sequentially and automatically moves.

When the set time of the timer 11 has elapsed, the air supply to the air motor 8 is interrupted and the air is supplied to the air cylinder 16. Then, the air cylinder 1
6 is extended to move the brush 9 around the base end of the arm 6.
Is lifted and rotated together with the air motor 8 in the counterclockwise direction in the drawing. Therefore, in this state, the deburring brush 9
At the same time, the brush 9 is retracted to a position separated from the component 3, so that a space for attaching and detaching the component 3 is secured.

Therefore, if the part 3 from which the burrs have been removed after the brush 9 is retracted is removed from the rotary table 2 and a new part is attached to the rotary table 2 and the start button 13 is depressed in the same manner, the same sequence as described above is performed. Since the deburring operation is performed, it is possible to remove burrs of a large number of parts in a uniform state without variation.

Note that the set time of the timer 11 and the pressure contact pressure of the brush 9 may be set appropriately according to the size of the component 3 and the burr removal strength, and the attachment / detachment of the component 3 and the activation of the timer 11 are automated. It is also possible to perform fully automatic deburring work.

Although the deburring brush 9 is driven by the air motor 8 and the brush moving means is constituted by the air cylinder 16 in the above embodiment, the actuator for driving the brush 9 and the brush are placed between the operating position and the retracted position. The structure of the brush moving means for moving is not limited to the embodiment.
Further, in the embodiment, the case where the deburring surface 4 is present on one end face of the component 3 has been described, but burrs generated on both end faces or the inner and outer circumferences of the ring-shaped component can be similarly removed. .

When removing burrs generated on the inner and outer peripheral surfaces of the component, the brush 9 may be driven to rotate about an axis substantially parallel to the rotation axis of the component 3, and the rotation axis of the brush 9 and the component By appropriately adjusting the intersecting angle or parallelism of the rotation axes of 3, the rotation speed of the component 3 due to the frictional force with the deburring brush 9 can be arbitrarily set.

[0020]

As is apparent from the above description, according to the present invention, the burr generated on the ring-shaped component can be easily and accurately removed only by attaching the component to the rotary table and starting the timer. Deburring work efficiency is improved.
