Among conventional cutting correction type devices, for example, a drill cutting type correction device places a test piece (hereinafter referred to as a workpiece) 2 on a fixed workpiece table 1 as shown in Fig. 2, and a clamp feeding cylinder. 3
It is fixed by a workpiece clamping tool 4 sent by. A drill 6 sent by a cutting feed cylinder 5 performs drill cutting on the fixed end face of the workpiece 2. The main body of the drill 6 is equipped with a cutting depth detector 7 composed of a differential transformer or the like, and a movable core 8 that comes into contact with a hole 9 provided on the work table 1 is displaced as the drill advances, and the amount of displacement is measured. Detected as drill cutting depth. This detection signal is input to a drill feed control section (not shown), and a drill feed amount control signal is output.

In the conventional device, when a workpiece is placed on the workpiece table 1, the contact surface S2 of the workpiece table 1, which comes into contact with the end surface opposite to the end surface of the workpiece to be cut by the drill, serves as a reference surface for setting the cutting depth. If the distance between this contact surface S 2 and the tip of the hit 9 is constant, and the distance between the hit 9 and the tip of the movable iron core 8 of the cutting depth detector 7 is 1 2 , then the distance between the drill 6 and the end surface of the workpiece to be cut is The distance l 1 is 1 1 =
By adjusting the length of the drill 6 in the axial direction so that the length of the drill 6 becomes 1 2 , the cutting depth can be controlled based on the detection signal of the cutting depth detector 7.

ものである。 Therefore, unless 1 1 = 1 2 , an error will occur in the cutting depth. In this case, since the workpiece contact surface S 2 of the work table 1 is used as the reference surface for adjusting so that 1 1 = 1 2 , if the thickness B of the work 2 varies, first adjust it so that 1 1 = 1 2 . Even if the depth was set, the difference would be 1 1 ≒ 1 2 due to the variation in thickness, and accurate depth control would not be possible. Furthermore, when placing the workpiece 2 on the workbench 1, a similar error may occur if there is dust on the placing surface and the cutting surface to be machined is slightly tilted when the workpiece 2 is fixed. be.

たものである。 In addition, since the cutting feed amount is controlled by receiving the signal from the cutting depth detector 7 while feeding the drill 6, the response of the feeding of the drill 6 is slightly delayed, and the drill may cut a little more when the cutting is completed. An error had occurred.

Therefore, in the cutting depth setting device, first set the cutting depth to zero, and then set the distance between the protrusion and the cutting feed means equal to the distance between the cutting means and the cutting surface of the workpiece. By adjusting the position of the cutting means, the cutting depth can be set based on the cutting surface of the workpiece, so even if the thickness dimension of the workpiece fixed to the fixed table changes, the cutting means will only need to be adjusted to the set cutting depth.

FIG. 1 is an explanatory diagram showing the configuration of a dynamic balance tester which is an embodiment of this invention. As an example, a drill cutting type correction device will be described. A workpiece 2 that requires correction is placed on a fixed workpiece table 1, and is clamped by a workpiece clamp table 11 sent by a clamp feed cylinder 3. The work clamp table 11 is equipped with a pulse motor 14 and pulleys 15, 1.
The taper moving table 13 is moved up and down by a feed screw 19 driven by a belt 20 wound around the belt 6, and the position of contact with the tapered surface changes depending on the vertical movement of the tapered moving table. Projection-shaped drill stand stopper 1 whose moving distance changes in the direction
A cutting depth setting device consisting of 2 is provided.
This is the rotation angle of the rotation shaft of the pulse motor 14,
By appropriately determining the ratio of the feed pitch of the feed screw 19 and the angle of the tapered surface with respect to the vertical movement of the tapered moving table 13, it is possible to move the feed screw in the horizontal direction in response to changes in the contact area with the tapered surface. The moving distance of the drill stand stopper 12 is determined. Therefore, for example, the cutting depth is set to zero at the position where the drill stand stopper 12 protrudes the most from the taper movable table 13, and the cutting depth can be arbitrarily set by driving the pulse motor 14.

る。 The drill 6 installed on the drill feed stand 10 is sent to the cutting surface of the work 2 by the cutting feed cylinder 5 with respect to the work 2 fixed by the work clamp stand 11. The drill feed base 10 has a limit switch operating rod 18, and this operation rod 18 is connected to the drill base stopper 12 by movement of the drill feed base.
A limit switch 17 is provided which is activated by coming into contact with the limit switch 17. Limit switch 17
As a result, a cutting completion signal is output to the cutting feed cylinder 5 according to a command from a cutting feed control device (not shown), and the drill feed base 10 is moved backward.

ズレたときも同様に正確な切削ができる。 In the correction device configured as described above, after first clamping the workpiece 2 with the workpiece clamping table 11, the pulse motor 14 is driven to set the taper moving table 13 to the zero cutting depth position, and the drill table stopper 12 is moved. If the distance between the drill stand 10 and the drill stand stopper 12 when pressed against the taper moving table 13 is 1 4 , then the distance 1 3 between the drill 6 and the end face of the workpiece to be cut is 1 3 = 1 4 . Adjust the axial length of the drill 6. By adjusting in this way, even if the thickness B of the workpiece 2 changes with reference to the contact surface S1 of the workpiece clamping table 11 with the end surface of the workpiece, the tip of the drill stand stopper 12 will adjust according to the change. The position changes and the relationship 1 3 = 1 4 is maintained. Therefore, by moving the taper moving table 13 and setting the cutting depth after such adjustment,
By setting the amount of rearward movement of the drill stand stopper 12 as the cutting depth, accurate cutting can be performed regardless of variations in the thickness of the workpiece 2. Accurate cutting is also possible even when the fixation of the workpiece is misaligned.

成すればよい。 In the above embodiment, the cutting depth is set by the rotation angle of the pulse motor 14, but a differential transformer may be used to control the amount of vertical movement of the tapered movable table. In short, the structure may be such that the amount of displacement of the protrusion in the direction parallel to the feeding direction of the cutting means can be exchanged for the amount of cutting depth with respect to the cutting surface of the workpiece.
