DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring apparatus for removing burrs of a work such as a metal plate generated by punching / pressing, mechanical cutting, laser processing, and the like.
More specifically, the present invention relates to a deburring apparatus which can remove burrs attached to the inside of a work such as a groove or a hole without deteriorating the accuracy of a product and which can be easily maintained.

[0002]

2. Description of the Related Art Generally, burrs are formed at corners of a machined or pressed part. If parts are processed and assembled without removing burrs generated in these processing steps, accurate assembly cannot be performed. Also, even when assembled into a machine, the burrs fall off and fall into the details of the machine, lowering the operation reliability of the machine or, in the case of a machine installed in a clean room, generating dust around the machine. It is discharged and has a bad influence on the surrounding environment. Further, if a part of the body such as a hand touches the portion where the burr is attached, "injury" may occur, which is dangerous. Especially in today's era of product liability, this should be avoided as much as possible.

[0003] By the way, conventionally, studies have been made to remove burrs by cutting or grinding, but mainly hydraulic pressure,
Valves and pipes of pneumatic equipment are made for relatively rigid parts as a whole, but there is not much solution for punching a plate with low rigidity as this part. A grinding wheel method and a grinding belt method for removing are mainly used. Also, in recent years, "Mounting a plurality of brush rods on a brush holding plate,
A vertical rotary brush type deburring machine that removes burrs of a work at the lower end of the brush rod by horizontally rotating the brush holding plate ”is also used.

[0004]

However, the above-mentioned conventional deburring apparatus has the following problems. In other words, in the grinding wheel method or the grinding belt method, the burrs inside the punched hole of the work cannot be sufficiently removed, and the work surface is simultaneously polished, so that the thickness of the work becomes thin. . In the case of the vertical rotating brush method, the burrs on the edge of the work cannot be sufficiently removed, and when a plurality of the vertical rotating brushes are arranged, the distance between the vertical rotating brush and the work is reduced. Variations occur, variations occur in the polishing state of the work surface, and furthermore, accurate spacing adjustment between the work and the plurality of vertical rotary brushes cannot be performed. And other issues.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to reduce wear of a grindstone and to remove both surface burrs and internal burrs.

By moving the movable frame 6 and connecting with the main body frame 5, the first deburring machine 1 and the second deburring machine 2 are connected to form a deburring device.

Next, each transfer device and the rotary grindstone 1
1. The rotary brush 22 and the rotary finish whetstone 32 are driven in synchronization with each other. Then, the work is supplied to the supply section of the first conveyor 12, and the transfer is started. The surface of the workpiece is removed while being transferred while being in contact with the rotating grindstone 11 of the first deburring machine 1.

Subsequently, the work is transferred to the second conveyor 22 and, while being transferred, the rotary brush 21 of the second deburring machine 2 removes burrs inside the holes and in the concave portions. in this case,
The untreated surface between the first row of rotating brushes 21 is processed by the second row of rotating brushes 21. Subsequently, while the work is transferred to the third conveyor 32 and transferred, the rotating brush 31 of the third deburring machine 3 removes burrs and baking remaining on the surface. The third deburring machine 3 is a wet type and prevents burning. Subsequently, the fourth conveyor 43
While being transferred from the holding roller 45 to the outlet, the attached gas is blown off and dried by the dry gas from the blowing pipes 42a and 42b. In addition, each rotating whetstone 11,
The rotation of the rotating brush 21 and the rotating finish whetstone 31 and the ejection of the blown gas may be performed before a device is provided in front of each device or at a required position, and the sensor is used to detect a workpiece before operation. . With this configuration,
The life of the grindstone, the brush and the like can be extended, and the power cost can be reduced.

Next, maintenance such as maintenance and inspection of the rotating grindstone 11 and the rotating brush 21 is required.
If it is preferable to work close to 1 from the viewpoint of workability, the movable frame 6 and the main body frame 5 are separated from each other, so that the work can be easily performed not only from the side but also from the front or the rear. Thus, maintenance workability is improved. When adjusting the bristle length (brush protrusion length) of the rotating brush 21 in the vertical axis rotating brush type deburring machine (second deburring machine) 2, the handle 89 is operated to drive the screw jack 81. The connection shaft 8
8, through the roller bearing 91, the vertical axis (brush holding axis)
The brush holder 92 attached to the 26 moves up and down by a spline groove 26 b around the vertical axis (brush holding axis) 26. As a result, all the brush holders 92 connected to the connecting shaft 88 move up and down at the same time, so that the height of the rotating brush 21 attached to each brush holder 92 can be simultaneously and uniformly adjusted.

It should be noted that the present invention is not limited to the above-described embodiments, but includes those which can be modified and implemented without departing from the gist of the present invention. Incidentally, in the above-described embodiment, an example has been described in which the first deburring machine and the third deburring machine are configured by one rotating grindstone, but a plurality of rotating wheels may be used in parallel. In this case, they may be formed from the same or different materials. In addition, although the example has been described in which the number of the vertical shaft rotating brush rows is two, three or more rows may be arranged. Although the drying device is provided, the final deburring machine may be a dry type and no drying machine may be provided. In addition, although the example in which the positioning of the movable frame is performed by fitting it into the framework of the main body frame has been described, the moving frame may be shortened by assembling it in an opposite manner without fitting. You may do so. In short, the present invention is to provide adjacent deburring machines for different types of polishing, and also to make one deburring machine separable from other deburring machines for easy maintenance, and a rotating brush. The feature is that the height adjustment can be performed integrally.
