Abstract

PURPOSE:To make it possible to precisely deburr a workpiece by mounting the workpiece freely to adjust its rotation and height on a clamp device, making a tool free to mount it in an arbitrary angle, and forcedly pressing the tool with prescribed constant pressure in deburring the middle part of a gear-shaped casting article in the axial direction. CONSTITUTION:By mounting a workpiece 2 on a clamp device 3, and adjusting the height of a deburring position such that said position faces a rotary grindstone 4, they are mounted on a rotary table on a frame 1. Then, a mounting angle alpha of the grindstone 4 against the workpiece is determined, and a machining table 21 is fixed to an XY table 20. And, with the starting of any machining, the workpiece 2 is turned with low speed in the Z direction, and simultaneously the grindstone 4 is also turned to allow a linear table 23 to move with the action of a cylinder, and thereby allowing the grindstone 4 to touch the workpiece. However, the grindstone goes back when grinding pressure is larger than pressing force by a weight 26, and rapidly travels to a B point at the instant it passes through an A point, allowing deburring to be performed successively. When deburring one surface of the workpiece is completed, the grindstone is reversely turned to deburr the other surface thereof. In such a way, it is possible to precisely deburr a workpiece even if there is any variation in its size.

is attached, and when the screw rods 8... rotate, the plate 11 is attached so as to be movable in the vertical direction. A rotary table 1 is mounted on the upper surface of the v-board 11, and is driven by a motor 13 which can change speed. That is, the motor shaft 14 of the motor 13 passes through the plate 11 and is fixed to the rotary table 12 via a key 15. The workpiece 2 is mounted on the rotary table 12 with a plurality of threaded rods 16..., nuts 17... and the tightening plate 1.
It is designed to be clamped with 8.

Next, the processing head 5 is constructed as follows.

A grate 19 is provided on the pedestal 1, and an XY table 20 is provided on this plate 19. This X
A rotary table 21 is rotatably supported on the upper surface of the Y table 20 and is tightened at a desired angle by a fastener 22. A linear table 23 is slidably provided on the upper surface of the rotary table 21. This linear table 23 is.

It consists of a lower stand 23a and an upper stand 23b, and the lower stand 23a
A pulley 24a is rotatably supported at the end of the grindstone 4 side, while a pulley 24a is rotatably supported at the end of the upper stand 23b on the opposite side from the grindstone 4.
A pulley 24b is rotatably supported, and these pulleys 24a
, 24b, a wire 25 is stretched, a weight 26 is suspended from one end of the wire, and the other end is connected to the pulley 241L+2.
4b is fixed with a wire holding fitting 27 provided in the middle,
A constant pressing force is applied to the linear table 23. A motor 29 is fixed to the upper part of the linear table 23 via metal fittings 28 and 28, and a grindstone 4 is rotatably attached to the tip of the motor 29.

Next, in order to perform deburring work using the deburring device configured as described above, the workpiece 2 is attached to the clamping device 3. For this purpose, the threaded rod 8 of the clamping device 3 is adjusted so that the height H to the deburr c of the workpiece 2 and the mounting height of the grindstone 4 of the deburring tool in the processing head 5 are equal.
Rotate... Next, the workpiece 2 is placed on the rotary table 12 of the clamp device 3, and then fixed with the screw rod 1ρ and the nut 17 via the clamping plate 18. Next, the attachment angle α of the grindstone 4 to the workpiece 2 is determined based on the shape of the workpiece. That is, after setting the rotary table 21 of the machining rod 5 at the above-mentioned mounting angle α, the rotary table 21 is attached to the XY table 20 using the fastener 22.
Next, the linear table 23 is moved in the X direction so that the grindstone 4 is separated from the workpiece 2 by a cylinder (not shown). Further, at this time, the linear table 23 is pressed in the Y direction by the weight 26. After doing this, when you press the start button (not shown), the workpiece 2
rotates at low speed in two directions as shown by the arrows. At the same time as the workpiece 2 rotates, the grindstone 4 rotates, the cylinder (not shown) for moving the linear table 23 returns to its original position, and the grindstone 4 and the workpiece 2 come into contact. At this time, when the rotation of the rotary table 21 causes the grinding pressure on the workpiece 2 to become larger than the pressing force exerted by the weight 26, the linear table 23 is pushed back in the It passes through and rapidly moves to point B. In this way, when the deburring work is completed over the entire circumference by sequential machining, the cylinder is operated to move the straight cheagle 23 into the Y direction.
At the same time as the workpiece 2 is pushed back in the direction, the rotation of the workpiece 2 is stopped, and as shown in FIG. 5, only one side of the protrusion 2a of the workpiece 2 shown by the solid line is deburred. To deburr the unprocessed part shown by the broken line, rotate the workpiece 2 in the opposite direction, that is, counterclockwise, and move the grindstone 4 at an angle α toward the unprocessed part.
Just tilt it and operate in the same way.

〔Effect of the invention〕

As explained above, in this invention, the workpiece is mounted on the clamp device in a freely rotatable and height-adjustable manner, and the C17 removal tool is placed on the XY table and attached to the workpiece as desired. Since it can be mounted at any angle and always presses against the workpiece with a constant pressing force, it automatically and continuously traces along the protrusion formed on the outer peripheral wall of the workpiece. Depending on the method, deburring can be performed. Therefore, it is possible to accurately deburr even when there are variations in dimensions in castings that are manufactured in small quantities in a wide variety of types, and the quality and processing time of deburring are more constant than when done manually.

Further, the device has a simple structure and can be provided at low cost.
