In addition, a control unit 53 such as a microcomputer electrically connected to each drive unit in order to control the drive of the above device.
An operation panel 54 for inputting various commands and information to the control section 53, and a memory 55 in which various information obtained by programs necessary for control, teaching, etc. are stored.

Next, the operation of this cap body hole processing device will be described. FIG. 6 is a flowchart showing the operation procedure. First, the operator puts the cap body 1 which is an object to be punched on the cap body mounting table 4, and then forms the center mark (not shown) of the cap body 1 on the outer peripheral collar portion 4a of the cap body mounting table 4. Align with the registered alignment mark (not shown). In this way, when the cap body 1 is set at a predetermined position with respect to the cap body mounting table 4, the worker operates the operation panel 54.
Gives a clamp command to the control unit 53. The control unit 53
In response to this clamp command, the cap body 1 is clamped by the first and second clamp means 8 and 20 (step S1). That is, the piston rod of the air cylinder 21 of the second clamp means 20 is lowered and the clamp portion 22
As a result, the upper portion of the cap body 1 is pressed. Thereafter, the pressure cam 7 is driven upward by the air cylinder 6 to operate the 11 first clamping means 8 (FIG. 2), respectively, and the discarding members 13 (FIG. 3) held by the respective clamping means 8 (FIG. 3). ) Are pressed against the inner surface regions of the cap body 1 corresponding to the respective drilling positions.

In this way, when the clamping of the cap body 1 by the first and second clamping means 8 and 20 is completed, the operator subsequently operates the operation panel.
By 54, the control unit 53 is provided with information regarding the hat body 1 that is the target of the punching process and an operation start command. As a result, based on the programs and various control data stored in the memory 55, the control unit 53 sequentially gives a control command to each drive unit, and the punching operation is executed in the following procedure.

That is, first, the drive units of the rotating mechanism, the advancing / retracting mechanism, the first and second elevating mechanisms, and the moving mechanism are operated, and step S2
As shown in, each control axis of the θ axis, the X axis, the Y axis, the A axis, and the Z axis is set to the origin position. Next, in step S3, one of the two drills 26a, 26b having different diameters is used.
It is determined whether to activate 6a. Now, for example, regarding the first drilling, assuming that the control data for starting the drill 26a is given to the memory 55 in advance by teaching, the process proceeds to step S4 and the other drill is drilled.
A rotation stop command to 26b and an air supply stop command to suction box 31 are given. However, in the initial state, the rotation of the drill 26b is stopped and the air supply to the drill 26b is also stopped, so that a new operation is not substantially performed in step S4.

Next, in step S5, the X-axis is moved so that the drill 26a moves to a position corresponding to the first hole drilling position of the cap body 1.
Axis, Y-axis, A-axis, θ-axis positioning control is performed. Specifically, the position of the moving table 18 in the X direction is moved and adjusted so that the cap body 1 moves to the position shown by the broken line in FIG. The rotation position of the rotary table 5 is adjusted so that the hole machining position of the rotary table faces the drill 26a (θ-axis control). Further, the height and posture of the drilling means 3 are adjusted by the control of the Y axis and the A axis so that the drill 26a is arranged on the normal line of the surface region at the first hole drilling position of the cap body 1. .

After that, the rotational driving of the drill 26a is started (step S6), the air supply to the drill 26a and the exhaust from the suction box 30 are started (step S7), and the servo motor 43 causes the drilling means 3 to operate. After being moved by a predetermined amount in the Z direction, drilling is performed by the drill 26a at the first drilling position of the cap body 1 (step S
8). In this case, as shown in FIG.
Since the drill 26a comes into contact with the cap body 1 and the hole is drilled after being pressed against the surface of the cap body 1, the pressing member 38 is constantly pressed against the surface of the cap body 1 by the biasing force of the spring 37. Therefore, the drilling process is performed, and burr is prevented from being generated on the front surface side of the cap body 1. Further, the drill 26a is the cap body 1
The punching is performed so that the throwing member 13 penetrates through to the middle of the throwing member 13, but the throwing member 13 is constantly pressed against the inner surface of the hat body 1 by the spring 11 even on the inner surface side of the hat body 1. Since the boring process is performed, the occurrence of burrs on the inner surface side of the cap body 1 is also prevented.

After this, the drill 26a retracts in the Z direction and is pulled out from the cap body 1 (step S9), and the first drilling process is completed. During this time, the chips adhering to the drill 26a due to the drilling are blown into the exhaust chamber 32 by the air blown from the air supply pipe 34, and efficiently through the exhaust pipe 36 without being scattered outside the suction box 31. It is discharged to the outside.

In this way, when the first drilling process is completed, the process proceeds to step S10, and it is determined whether or not all the drilling processes have been completed. If you still have holes,
Returning to step S3 again, it is determined whether or not to activate the drill 26a. Now, for example, regarding the second drilling, assuming that the control data for starting the drill 26b is given to the memory 55 in advance by teaching,
After it is confirmed in step S11 that the drill 26b is activated, the process proceeds to step S12.

In step S12, a rotation stop command for the drill 26a and an air supply stop command for the suction box 31 are given. As a result, the rotation of the drill 26a is stopped and the supply of air to the drill 26a is stopped.

After that, the process proceeds to step S13 so that the drill 26b moves to a position corresponding to the second hole processing position of the cap body 1,
Positioning control for the X-axis, Y-axis, A-axis, and θ-axis is performed. Specifically, the position of the moving table 18 in the X direction is moved and adjusted so that the cap body 1 moves to the position shown by the solid line in FIG. 7 (control of the X axis), and the second position of the cap body 1 is adjusted. The rotary position of the rotary table 5 is adjusted so that the hole machining position of the rotary table faces the drill 26b (θ-axis control). Further, the height and the posture of the drilling means 3 are adjusted by the control of the Y axis and the A axis so that the drill 26b is arranged on the normal line of the surface region at the second processing position of the cap body 1.

After that, the rotational driving of the drill 26b is started (step S14), the air supply to the drill 26b and the exhaust from the suction box 31 are started (step S15), and in that state the drilling means 3 is placed in the Z direction. After being transferred by a fixed amount, drilling is performed at the second hole drilling position of the cap body 1 by the drill 26b in the same manner as at the first hole drilling position (step S16). After this, the drill 26b is Z
And is pulled out from the cap body 1 (step S1
7), the second drilling process is completed.

In this way, the process proceeds to step S10 again, and thereafter, for the third and subsequent drilling processes, the step corresponding to each hole diameter is performed.
S3 → S4 → S5 → S6 → S7 → S8 → S9 → S10 or steps S3 → S
One of the operations of 11 → S12 → S13 → S14 → S15 → S16 → S17 → S10 is sequentially selected and executed.

Then, when the final drilling is completed, the supply and exhaust of air to the drill 26a or 26b which has been in the driving state until then is stopped (step S1).
8), rotation of the drill 26a or 26b is also stopped (step S
19), cap body 1 by first and second clamping means 8, 20
The clamp is released (step S20).

In this way, all the boring processing for the cap body 1 is completed,
A plurality of holes are sequentially and accurately formed at predetermined positions of the cap body 1 in a state where no burr is generated.

The discard member 13 held by the first clamp means 8
Once drilled, drill 2a on itself as well.
Alternatively, since the hole is formed by 2b, it is replaced by the operator every time the drilling work is performed.

Examples of the reinforcing fibers of the cap body 1 made of the fiber-reinforced resin include high-strength fibers such as polyamide fiber, carbon fiber, metal fiber and glass fiber, and examples of the resin include epoxy resin and polyester resin. The synthetic resin of.

With respect to the shapes of the drills 26a and 26b, for example, a fiber drill as shown in FIG. 8, an end mill as shown in FIG. 9, and an ordinary drill as shown in FIGS.

However, the degree of burr suppression is slightly different depending on the type of drill, and even if the same type of drill changes the angle β of the cutting edge. When actually drilling was performed using the drills shown in Figs. 8 to 11 and the degree of burr generation suppression was measured, the angle β of the fiber drill (Fig. 8) and the cutting edge was set to 150 degrees. The best results were obtained when using a continuous drill (Fig. 11), which used an end mill (Fig. 9) and an ordinary drill (Fig. 10) with the cutting edge angle β set to 118 degrees. When it did, the result which was a little inferior to the former was obtained.

In order to suppress the occurrence of burrs, it is preferable to increase the pressing force of the pressing member 38 on the cap body 1. Therefore, for example,
As shown in FIG. 12, it is desirable to reduce the area of the pressing surface 38b of the pressing member 38. In the example of Fig. 12, the drill through hole
The inner diameter of 38a is 6 mm, the maximum outer diameter of the pressing member 38 is 14 mm,
The case where the diameter of the pressing surface 38b is set to 8 to 9 mm is shown. It is desirable to select the difference between the diameter of the pressing surface 38b and the inner diameter of the drill through hole 38a to be 1 to 5 mm, preferably 2 to 3 mm.

Further, the pressing member 38 may be composed of a blind plate having no drill through hole 38a, and in this case, the effect of suppressing the occurrence of burrs is further enhanced. However, when the drilling process is performed, a hole is also formed in the blind plate pressing member 38, so it is necessary to replace the pressing member each time the drilling process is performed. There is.

The discarding member 13 held by the first clamp means 8 is preferably made of iron, brass, or the like, which is easy to process and inexpensive. It is also possible to use a hard plastic material such as nylon. Furthermore, for example, one side is 10
If you finish it with a hexagon of mm and change the surface pressed against the cap body 1 each time when drilling with a drill, you can use one member for 6-degree drilling work and save the used material. Is planned.

In the above embodiment, the discard member 13 is pressed against the cap body 1 by the first clamp means 8 having the spring 11 and the pressing cam 7. However, the discard member 13 is pressed against the cap body 1 by an air cylinder, for example. You may make it press.

In addition, if the size and shape of the cap body 1 and the number and positions of the processed holes are changed, a unit including the pressing cam 7, the first clamp means 8 and the cap body mounting table 4 is prepared in advance, It can be easily dealt with by simply replacing the unit.
In that case, it is necessary to store control data corresponding to various cap bodies 1 in the memory 55 in advance by teaching.

When a drilling operation was actually performed using the apparatus shown in FIG. 1 under the following processing conditions, the occurrence of burrs could be accurately suppressed.

Machining conditions Drill rotation speed 2100 rpm Pressing force of pressing member 38 on cap body 18 to 20 kg Pressing force of discarding member 13 on cap body 15 to 20 kg Hole diameter and number φ6 mm × 11 The rotation speed of the drill is A range of 1500-3800 rpm is preferred with more favorable results being obtained at 2000-2300 rpm.

(Effect of the Invention) According to the invention described in claim 1, at the time of drilling with the drill, the pressing member is pressed against the surface of the cap body, and then the drill comes into contact with the surface of the cap body to carry out the drilling. For this reason, drilling is performed while the surface of the cap body is always pressed by the pressing member, and burr generation can be suppressed.

According to the second aspect of the present invention, since the drilling process is performed with the drill while the discarding member is pressed against the inner surface region of the cap body corresponding to the drilling position, the occurrence of burrs can be suppressed more reliably. .

According to the invention described in claim 3, since the cap body is drilled while the upper portion of the cap body is pressed by the second clamp means, the cap body is accurately held at a predetermined position, The accuracy of the drilling position can be improved.

According to the fourth aspect of the invention, a plurality of holes can be sequentially and accurately formed at predetermined positions of the cap body on the basis of the programs and various data stored in the memory.
