SUMMARY OF THE INVENTION A method for cutting a component cable of a coaxial cable for equipment wiring according to the present invention is a method for rotating a coaxial cable for equipment wiring around its axis, and a blade in a direction orthogonal to the coaxial cable. It is characterized in that the component is cut by advancing and biting the coaxial cable in a direction perpendicular to the coaxial cable.

As described above, while rotating the coaxial cable for device wiring around its axis, the blade is advanced in the direction orthogonal to the coaxial cable and bites in the direction orthogonal to the coaxial cable, thereby constituting the component. When the blade is cut, the blade goes straight without rotating around the coaxial cable, so that it is possible to easily and accurately set the biting allowance for the coaxial cable. The cutting up to the element can be performed accurately.

Further, in the case of this cutting method, the coaxial cable rotates and the blade does not rotate. Therefore, by using a rotary system having a simple structure and a blade having a simple structure, specific components of the coaxial cable can be obtained. Can be cut up to.

Further, since the blade bites in the direction orthogonal to the coaxial cable, the cutting surface is clean and chips are not generated during cutting.

The coaxial cable component cutting device for equipment wiring according to the present invention has a coaxial rotating body having a coaxial cable through hole through which a coaxial cable for equipment wiring penetrates and a rotatable body, and a coaxial cable through hole. Chuck for fixing the coaxial cable to the rotating body, rotation driving means for rotating the rotating body around its axis, and surrounding its components in a direction orthogonal to the coaxial cable on the tip side of the rotating body. It has a structure including a blade that cuts in a direction and a blade drive mechanism that moves the blade in a direction orthogonal to the coaxial cable and bites into the coaxial cable.

In such a coaxial cable component cutting device for equipment wiring, since the coaxial cable rotates and the blade does not rotate, the structure of the rotating system can be simplified, and the device can be used more easily than before. It can be constructed at low cost.

Further, since the blade moves straight around the coaxial cable without rotating, it is possible to easily and accurately set the biting allowance for the coaxial cable. Therefore, even if the coaxial cable having a small outer diameter is used, it is possible to set the bite. It is possible to accurately cut the components.

Further, since the same portion of the coaxial cable is cut at a right angle with one blade, there is an advantage that the cut end is clean, and there is an advantage in cutting chips as in the case of cutting the same portion with a plurality of blades in a groove shape. It is possible to prevent the occurrence of a large number of occurrences, which causes a failure.

The coaxial cable component cutting device for equipment wiring according to the present invention has a coaxial cable through hole through which a coaxial cable for equipment wiring penetrates, which has a shaft hole and is rotatable, and a coaxial cable penetrating body. A chuck for fixing the coaxial cable passed through the hole to the rotating body, a rotation driving means for rotating the rotating body around its axis, and a centering for centering the coaxial cable protruding from the tip of the rotating body. Tool, a blade for circumferentially cutting the component in a direction orthogonal to the coaxial cable between the tip of the rotating body and the centering tool, and the blade in a direction orthogonal to the coaxial cable. It has a structure including a blade drive mechanism for moving and biting into the coaxial cable.

When the centering tool for centering the coaxial cable protruding from the tip of the rotating body is provided in this manner, the coaxial cable can be accurately centered by the rotating body and the centering tool, and the coaxial cable can be centered. Even if the cable is thin, it is possible to reliably cut the required components in the circumferential direction when cutting the required components with the blade. It is possible to prevent cutting.

In this case, it is preferable that an adapter sleeve having a hole having an inner diameter corresponding to the outer diameter of the coaxial cable for device wiring to be processed is set in the coaxial cable through hole of the rotating body.

When the adapter sleeve having the inner diameter hole corresponding to the outer diameter of the coaxial cable to be processed and set in the coaxial cable through hole of the rotating body is used, the outer diameter of the coaxial cable to be processed is When the coaxial cable changes, it can be replaced with an adapter sleeve having an inner diameter corresponding to the outer diameter of the coaxial cable, so that the size of the coaxial cable can be changed without replacing the rotating body.

The rotating body has a rotating body frame having a shape in which a small-diameter cylindrical portion and a large-diameter cylindrical portion are connected by a stepped portion, and a coaxial cable through hole through which a coaxial cable for device wiring penetrates. It is preferable that the rotary body has a rotary head that is replaceably attached to the small-diameter cylindrical portion of the rotary frame.

When the rotating body head is replaceably attached to the small-diameter cylindrical portion of the rotating-body frame having the shape in which the small-diameter cylindrical portion and the large-diameter cylindrical portion are connected by the step, the rotating body is constructed. The length of the rotating body head, which is a portion through which the device-wiring coaxial cable penetrates, is shortened, so that the constituent elements of the device-wiring coaxial cable can be easily cut. Also, by changing the rotary head, it is possible to cope with a change in the size of the coaxial cable.

Further, the rotary body has a rotary body frame having a shape in which a small-diameter cylindrical portion and a large-diameter cylindrical portion are connected by a stepped portion, and a coaxial cable through hole through which a coaxial cable for device wiring is penetrated. And a large-diameter cylindrical portion of the rotating body frame having a rotating body head that is replaceably attached to the small-diameter cylindrical portion of the rotating body frame and a coaxial cable guide hole that penetrates a coaxial cable for device wiring. It is preferable that the guide body is detachably attached to the structure.

When the rotating body head is attached to the small-diameter cylindrical portion of the rotating body frame and the guide body is attached to the large-diameter cylindrical portion of the rotating body frame in this way to construct the rotating body, guide bodies of different lengths are used. This makes it possible to easily cope with changes in the length of the coaxial cable for device wiring.

Further, the blade driving mechanism includes a guide rail that defines a moving direction in which the blade moves in a direction orthogonal to the coaxial cable, a slider that is moved by being guided by the guide rail, and the slider that moves along the guide rail. A drive source to be moved, and an XY table mounted on the slider for adjusting the position of the blade in a direction orthogonal to the coaxial cable and a direction parallel to the coaxial cable can be provided.

With such a configuration, the position of the blade with respect to the coaxial cable is set by the XY table and the biting amount is set in advance, and thereafter, the slider is driven back and forth by the drive of the drive source having a predetermined stroke. It is very easy to use.

The blade drive mechanism has an independent structure for each cut portion of the coaxial cable, and the blades can be arranged at different positions in the longitudinal direction of the coaxial cable.

With such a structure, by using the blade drive mechanism at that position, it is possible to efficiently cut at a plurality of positions without moving the blade to the next cutting position of the coaxial cable.

1 and 2 show a first example of an embodiment of a coaxial cable component cutting device for equipment wiring according to the present invention.

The apparatus for cutting a coaxial cable component for equipment wiring of this example has a structure suitable for a case where the length of the equipment wiring coaxial cable 1 is relatively long (for example, 100 mm to 150 mm).

This device wiring coaxial cable component cutting device has a rotatable cylindrical body 7 having a coaxial cable through hole 6 through which the device wiring coaxial cable 1 penetrates and which is rotatable. The rotating body 7 has a pillow portion 9 through a bearing 8.
Is horizontally supported by a work table (not shown).

A chuck 10 composed of a coaxial cable holding screw for fixing the coaxial cable 1 passed through the coaxial cable through hole 6 to the rotating body 7 is screwed in the rotating body 7 in the radial direction.

Further, the rotary body 7 is provided with a rotation drive means 11 for rotating the rotary body 7 around its axis. The rotation driving means 11 includes a motor 12 supported by a workbench (not shown), a pulley 13 attached to an output shaft 12a of the motor 12, a pulley 14 attached to the rotating body 7, and a space between these pulleys 13. The timing belt 15 is stretched around.

On the tip end side of the rotating body 7, a centering tool 16 for fitting the coaxial cable 1 projecting from the tip end of the rotating body 7 and centering the same is supported and arranged on a workbench (not shown). There is. A hole 16a into which the coaxial cable 1 is fitted is provided at the tip of the center projecting tool 16.

Between the tip of the rotating body 7 and the centering tool 16, a blade 17 for cutting the constituent elements in the circumferential direction in a direction orthogonal to the coaxial cable 1 is orthogonal to the coaxial cable 1. It is arranged in the orientation. A blade tip 17e at the tip of the blade 17 is formed obliquely so as to easily bite into the coaxial cable 1.

The blade 17 is supported by a blade drive mechanism 18 that moves in the horizontal direction orthogonal to the coaxial cable 1 and bites into the coaxial cable 1. The blade drive mechanism 1
Reference numeral 8 denotes a blade holder 19 that supports the blade 17, and a guide rail 20 that is supported by a workbench (not shown) in a direction orthogonal to the coaxial cable 1 and that defines the moving direction of the blade 17.
A slider 21 that supports the blade holder 19 and slides along the guide rail 20; an air cylinder 22 as a drive source that moves the slider 21 back and forth in the direction of the guide rail 20; And a stopper 23 for determining the bite amount of the blade 17 with respect to the coaxial cable 1.

Next, a method for cutting a coaxial cable constituent element for equipment wiring by such a device for cutting a coaxial cable constituent element for equipment wiring will be described.

First, the coaxial cable through hole 6 of the rotating body 7
Through the coaxial cable 1 that has been cut to a required length in advance, and insert the tip of the coaxial cable 1 passing through the rotating body 7 into the hole 16a of the centering tool 16 to
With the coaxial cable 1 being centered by the centering tool 16 and the centering tool 16, the rotating body 7 is rotated by the rotation driving means 11 to rotate the coaxial cable 1 around its axis, and in this state the blade 17 is moved. The coaxial cable 1 by the blade drive mechanism 18
Is moved in a direction orthogonal to the above, and a required biting allowance is bitten in a direction orthogonal to the coaxial cable 1 to cut a required component of the coaxial cable 1 in the circumferential direction. At this time, when the blade drive mechanism 18 drives the air cylinder 22 as a drive source, the slider 21 causes the slider 21 to move.
0, and the blade 17 supported by the slider 21 via the blade holder 19 is also moved forward by the forward movement of the slider 21.
When 1 hits the stopper 23 and stops, in this state, the cutting margin of the blade 17 with respect to the coaxial cable 1 is automatically determined. Therefore, it is necessary to set the position of the stopper 23 or the position of the contact portion on the slider 21 side that contacts the stopper 23 in advance.

When the cutting is completed, the coaxial cable 1 extracts the components beyond the cut portion to expose the inner layer.

Incidentally, the cutting of the components of the coaxial cable 1 as shown in FIG. 9 may be performed first at the 4a position, then at the 3a position, and finally at the 2a position, or at all the positions at the same time. You may disconnect.

Further, the insulating layer 4 is not cut, but only the jacket 2 and the outer conductor 3 are cut by the method and apparatus of the present invention.
The stripping of the insulating layer 4 can also be performed using an existing device.

When the components of the coaxial cable 1 are cut in this way, the blade 17 moves straight without rotating around the coaxial cable 1, so that the biting allowance for the coaxial cable 1 can be set easily and accurately. Therefore, even the coaxial cable 1 having a small outer diameter can accurately cut the specific components.

Further, in such a device for cutting a coaxial cable component for equipment wiring, since the coaxial cable 1 rotates and the blade 17 does not rotate, the structure of the rotating system can be simplified, and the device is conventionally used. It can be constructed at a very low cost as compared with.

Further, in this device, the same portion of the coaxial cable 1 is cut by one blade 17 in a direction orthogonal to each other.
There is an advantage that the cut end is clean, and the cause of the failure can be avoided because chips are not generated.

In this case, since the coaxial cable 1 is centered by the rotating body 7 and the centering tool 16 and the required components are cut by the blade 17, the required components are cut when the blade 17 cuts the required components. The components up to can be easily cut in the circumferential direction.

Further, since the blade drive mechanism 18 sets a necessary biting allowance of the blade 17 with respect to the coaxial cable 1, the blade 1
It is possible to prevent cutting of the components inside thereof when cutting the required components at 7.

Further, the blade driving mechanism 18 has a blade holder 19 for supporting the blade 17, a guide rail 20 for defining the moving direction of the blade 17, and a slider 21 for supporting the blade holder 19 and sliding along the guide rail 20. And the drive source 22 for moving the slider 21 back and forth in the direction of the guide rail 20, and the stopper 23 for determining the bite allowance of the blade 17 with respect to the coaxial cable 1, the drive source 22 is moved forward. When driven, blade holder 19
When the slider 21 supporting the slider moves forward along the guide rail 20 and the slider 21 hits the stopper 23, the blade 17 supported by the blade holder 19 is automatically stopped at a position where it bites into the coaxial cable 1. As a result, the blade 17 can be automatically positioned.

FIG. 3 shows an example of each blade and blade holder in the case of cutting each location of the coaxial cable 1 together.

In this case, as shown in the drawing, a jacket cutting blade 17a for cutting the jacket 2 of the coaxial cable 1, an outer conductor cutting blade 17b for cutting the outer conductor 3, and an insulating layer cutting blade for cutting the insulating layer 4. 17c is set in the blade holder 19 with the position of the tip thereof being different depending on the cutting thickness. These blades 17a-1
The blade edge of 7c is also formed obliquely as shown in FIG.

When the blade drive mechanism 18 having the blade holder 19 in which the jacket cutting blade 17a, the outer conductor cutting blade 17b, and the insulating layer cutting blade 17c are set together, the jacket 2 of the coaxial cable 1 and the outside The conductor 3 and the insulating layer 4 can be simultaneously cut at different cutting positions, and the work efficiency can be improved.

According to the method for cutting a coaxial cable component for equipment wiring according to the present invention, the blade is advanced in a direction orthogonal to the coaxial cable while rotating the equipment wiring coaxial cable around its axis. Since the component is cut by biting in the direction orthogonal to the coaxial cable, the blade goes straight without rotating around the coaxial cable, which makes it easy and accurate to set the biting allowance for the coaxial cable. Can be performed, and thus even a coaxial cable with a small outer diameter can be accurately cut to its specific component.

Further, in the case of this cutting method, the coaxial cable rotates and the blade does not rotate. Therefore, by using a rotary system having a simple structure and a blade having a simple structure, specific components of the coaxial cable can be obtained. Can be cut up to.

Further, since the blade bites in the direction orthogonal to the coaxial cable, the cutting surface becomes clean and chips are not generated during cutting, and the cause of failure can be avoided.

Further, the apparatus for cutting a coaxial cable constituent element for equipment wiring according to the present invention has a coaxial rotor having a coaxial cable through hole for allowing a coaxial cable for equipment wiring to penetrate therethrough and a rotatable body, and a coaxial cable through hole. A chuck for fixing the coaxial cable passed through the rotor to a rotating body, a rotation driving means for rotating the rotating body around its axis, and its constituent elements in a direction orthogonal to the coaxial cable on the tip side of the rotating body. Since it has a structure that includes a blade that cuts in the circumferential direction and a blade drive mechanism that moves the blade in a direction orthogonal to the coaxial cable and bites into the coaxial cable, the coaxial cable is The blade does not rotate due to rotation, and therefore, the structure of the rotating system can be simplified, and the device can be constructed at a very low cost as compared with the conventional one.

Further, since the blade moves straight about the coaxial cable without rotating, it is possible to easily and accurately set the biting allowance for the coaxial cable. Therefore, even if the coaxial cable with a small outer diameter is used, it is possible to set a specific value. It is possible to accurately cut the components.

Further, in this device, since the same portion of the coaxial cable is cut at a right angle with one blade, there is an advantage that the cut end is clean, and when the same portion is peeled and cut into a groove shape with a plurality of blades. As described above, it is possible to avoid the occurrence of a large number of chips and causing a failure.

In particular, when the centering tool for centering the coaxial cable protruding from the tip of the rotating body is provided, the coaxial cable can be accurately centered by the rotating body and the centering tool, and the blade can be accurately centered. When the required component is cut by, it is possible to accurately perform the cutting up to the required component in the circumferential direction, and prevent the inside component from being cut when the required component is cut. be able to.

If an adapter sleeve having an inner diameter hole corresponding to the outer diameter of the coaxial cable to be processed and set in the coaxial cable through hole of the rotating body is used, the outer diameter of the coaxial cable to be processed is changed. In such a case, the size of the coaxial cable can be changed without replacing the rotating body by replacing the rotating body with an adapter sleeve having an inner diameter corresponding to the outer diameter of the coaxial cable.

Further, when the rotating body is constructed by replaceably mounting the rotating body head on the small diameter cylindrical portion of the rotating body frame having the shape in which the small diameter cylindrical portion and the large diameter cylindrical portion are connected by the step portion,
The length of the rotating body head, which is a portion through which the device-wiring coaxial cable penetrates, is shortened, so that the components of the device-wiring coaxial cable can be easily cut.
Also, by changing the rotary head, it is possible to cope with a change in the size of the coaxial cable.

Further, when the rotating body head is attached to the small-diameter cylindrical portion of the rotating body frame and the guide body is attached to the large-diameter cylindrical portion of the rotating body frame to form the rotating body, guide bodies of different lengths are used. This makes it possible to easily cope with changes in the length of the coaxial cable for device wiring.

Further, the blade drive mechanism defines a guide rail for moving the blade in a direction orthogonal to the coaxial cable, a slider which is guided by the guide rail, and a slider which moves along the guide rail. When the drive source for moving and the XY table mounted on the slider for adjusting the position of the blade in the direction orthogonal to the coaxial cable and the direction parallel to the coaxial cable are provided, the XY table is provided. By setting the position of the blade with respect to the coaxial cable and setting the bite amount in advance with the table, the subsequent operation can be done simply by driving the slider back and forth by driving the drive source with a defined stroke, which is extremely convenient. There is an advantage to get better.

If the blade drive mechanism has an independent structure for each cut portion of the coaxial cable and the blades are arranged at different positions in the longitudinal direction of the coaxial cable, the blade drive mechanism at that position is By using it, it is possible to efficiently cut multiple points without moving the blade to the next cutting position of the coaxial cable. Further, the position of each blade can be easily set independently.
