Description

[Detailed description of the invention] [Industrial application field] This invention is a test to remove machining burrs generated during the preparation process (cutting and cutting processes) of various test pieces (tensile test pieces, Charpy test pieces, etc.) This invention relates to an automatic piece deburring device.

[Conventional technology]

Conventional deburring of various test specimens was entirely done manually. That is, for example, in the case of a Charpey test piece, minute burrs are generated on the side and end surfaces during the four-side grinding process. In the next step, the Shapey test piece is notched to complete the processing process, but the notch requires an accuracy of ±0.05mm.

Therefore, in the conventional work, deburring of each test piece was carried out manually using a belt sander, file, etc., which was a major obstacle to automation and unmanned work in the test piece manufacturing process.

[Problems that the idea should solve]

The present invention improves the conventional method as described above and provides a device suitable for automated and unmanned machining deburring of various test pieces.

[Means for solving problems]

The present invention has been made to advantageously achieve the above object, and its gist is to form a test piece passing path on one side of a cross-shaped base, and to connect a moving mechanism to the path with a drive mechanism. The frames are engaged and arranged, and an alignment frame having a test piece alignment section having an alignment length and a distance d for metal test pieces having machined burrs is fixedly arranged on the upper surface of the movable frame, and Another aspect of the present invention relates to an automatic test piece deburring device characterized in that rotary cutters are arranged on both sides of the passageway so as to be movable in a direction crossing the passageway.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing the overall configuration of the device of the present invention, in which 1a and 1b are cross-shaped bases integrally formed at right angles to each other, and 2 is one base of the cross-shaped bases. A groove engraved on the surface of the base 1a, 3 a movable frame that engages with the groove and is movable in the longitudinal direction of the base 1a, and 4 a test piece fixed on the movable frame 3. 5 is a screw jack engaged with one end of the movable frame 3 in order to move the movable frame 3 forward and backward; 6 is a rotary motor for driving the screw jack 5; 7; are test pieces (in the illustrated case, Charpey test pieces) arranged in the alignment frame 4.

By starting the rotary motor 6, the screw jack 5 is connected to the base 1a.
The movable frame 3 engaged with the groove 2 is guided by the groove 3 and moves back and forth in the longitudinal direction of the base 1a.

8a and 8b are deburring cutter housings, 9
a and 9b are deburring cutter housings 8
The deburring cutters 9c and 9d are rotatably disposed at a and 8b, and the shafts of the cutters 9a and 9b are respectively designated by 9c and 9d. Reference numeral 10 denotes a deburring cutter rotation motor, which is incorporated into the cutter housings 8a and 8b.

11 is a groove 2 formed in the base 1a on the base 1b.
The bottoms of the deburring cutter housings 8a, 8b are slidably fitted into the slide rails fixedly perpendicular to the slide rails. This allows the deburring cutter housing to slide on the rail and adjust the amount of penetration into the test piece.

12 is the deburring cutter housing 8a, 8b
The built-in guide provided on the upper side of the cutter increases the stability of the deburring cutter housings 8a and 8b during deburring work. Reference numeral 13 denotes a holding plate provided opposite the movable frame 3 from the built-in guide 12, and serves to prevent the test piece from jumping up during deburring.

Here, as the deburring cutter, a flap wheel made by pasting sandpaper together in a cylindrical shape or the like can be used.

Further, the positions of the deburring cutter housings 8a and 8b may be set manually or by providing screws and rotating and moving them using a motor. It can be fixed at any desired position, for example, by a nut that fits into a screw screw.

The relationship between the alignment frames 4, 4 and the test piece 7 is as shown in FIG. Since it is centered by itself, it is possible to simultaneously and uniformly remove the burrs generated and attached to both end surfaces of the test piece 7.
This is extremely desirable.

Next, how to use it will be explained.

First, the rotary motor 6 is started to move the movable frame 3 forward or backward, and the alignment frame 4 on the frame 3 is separated from the deburring cutter housings 8a, 8b.

Next, the machined test pieces 7 (10 standard Shapey test pieces in the illustrated case) are arranged and placed on the alignment frame 4. Next, according to the length of the test piece 7, the deburring cutter housings 8a, 8b are moved to the moving frame 3.
Move it to a predetermined position opposite to the passing position. In this state, the cutter housing is fixed. All deburring preparations are now complete.

Then, start the cutter rotation motor 10,
The deburring cutters 9a and 9b are rotated at high speed, and the rotating motor 6 for driving the moving frame is started to move the frame 3 along the groove 2 of the base 1a, while the test piece 7 is being rotated at high speed. Deburring cutter 9
Enter between a and 9b. At this time, the holding plate 13 is lowered directly above the test piece to prevent the test piece from jumping up.

By repeating these series of operations, the test piece 7 is deburred in sequence and efficiently.

Here, although the above description has been made with respect to a Charpy test piece, it is clear that it is equally applicable to a tensile test piece or the like.

[Effect of idea]

As described above, the present invention uses a simple device configuration to remove machining burrs from various test pieces.
Deburring is now possible without any manual effort,
It can be used to achieve great effects when attempting to automate and unmanned test piece processing.
