ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an automatic cutting and crimping apparatus, and relates, more particularly, to an automatic cutting and crimping apparatus for cutting an electric wire (covered wire) to be used for a wiring harness (an assembled wire for a car) and for crimping a terminal (a compression ring) to both ends of the wire after stripping the wire of its cover at both ends.
Japanese Patent Application Laid-open No. 8-102354 discloses a both-end crimping apparatus for crimping both ends of a covered wire.
SUMMARY OF THE INVENTION
According to the investigation by the present inventor, there is considered available a both-end crimping apparatus
1
as shown in FIG.
8
.
The apparatus
1
has a supply station
3
having a large number of wire supply tubes
3
a
on a base stand
2
, as shown in FIG.
8
.
The supply station
3
is provided to be able to move in both directions of an arrow mark e.
A turning arm
4
is provided at an exhaust side of the supply station
3
. The turning arm
4
is provided with clamping means (not shown) for clamping an electric wire W supplied from the supply station
3
.
The turning arm
4
can move (turn) freely in left and right directions as shown by an arrow mark with respect to the base stand around an axis
5
. A head portion
4
a
of the turning head
4
is designed to be positioned at a reference position H, at a maximum turn processing position J that forms a maximum turn angle with the reference position H, and at an intermediate processing position I between these two points, respectively, by the turn of the turning arm
4
. Further, the head portion
4
a
of the turning arm
4
is structured to face a wire cutting section
6
A at the reference position H. to face a covered wire stripping section
6
B at the intermediate position I, and to face a terminal crimping section
6
C at the maximum turn processing position J, respectively.
Further, a first carrying section
7
is provided on the base stand
2
, and this first carrying section
7
can move freely in an arrow mark n direction and an arrow mark m direction.
The first carrying section
7
is provided with four clamping sections of first to fourth clamping sections
7
a
to
7
d
at equal distances. The first clamping section
7
a
is moved between the reference position H and a first processing position K, the second clamping section
7
b
is moved between the first processing position K and a second processing position L, the third clamping section
7
c
is moved between the second processing section L and a third processing section M, and the fourth clamping section
7
d
is moved between the third processing section M and a fourth processing section N, respectively.
A second carrying section
8
is disposed at the first processing position K of the first carrying section
7
, and this second carrying section
8
can move freely in an arrow mark p direction. The second carrying section
8
has a clamping section
8
a
and can carry a clamped wire W to a position opposite to a cover stripping section
6
D by moving in the arrow mark p direction.
A third carrying section
9
is disposed at the second processing position L of the first carrying section
7
, and this third carrying section
9
can move freely in an arrow mark q direction. The third carrying section
9
has a clamping section
9
a
and can carry a clamped wire W to a position opposite to a cover stripping section
6
E by moving in the arrow mark q direction.
A clamping section
6
F is provided at the third processing position M of the first carrying section
7
, and a wire exhausting section
6
G is provided at the fourth processing section N of the first carrying section
7
.
Based on the above-described structure, at first, the electric wire W is supplied to the turning arm
4
from the supply station
3
, and the supplied wire W is clamped by the clamping means not shown, with the front end side of the electric wire W set in a status of being projected from the head portion
4
a
of the turning arm
4
.
Next, the electric wire W projected from the head portion
4
a
of the turning head
4
is cut by the wire cutting section
6
A, and the turning arm
4
is turned from the reference position H to the intermediate processing position I.
Next, an insulating cover member at one end terminal of the electric wire W is stripped by the cover stripping section
6
B, and the turning arm
4
is turned from the intermediate position I to the maximum turn processing position J.
Then, a terminal is crimped to a conductive wire of the electric wire W by the terminal crimping section
6
C, and the turning arm
4
is returned from the maximum turn processing position J to the reference position H. Thus, a terminal processing at one end side of the electric wire W finishes.
When the turning arm
4
has returned to the reference position H, the first carrying section
7
moves in the arrow mark m direction to position the first clamping section
7
a
at the reference position H, and the electric wire W is drawn out by a predetermined volume by the head portion
4
a
of the turning arm
4
. The first clamping section
7
a
of the first carrying section
7
clamps this drawn-out electric wire W, and the first carrying
7
moves in the arrow mark n direction to move the first clamping section
7
a
to the first processing position K.
Next, the clamping section
8
a
of the second carrying section
8
re-clamps the electric wire W, and the second carrying section
8
moves in the arrow mark p direction to move the electric wire W to a position near the cover stripping section
6
D.
Next, an insulating cover member at the other end terminal of the electric wire W is stripped by the cover stripping section
6
D, and then the second carrying section
8
returns to the original position.
Next, the second clamping section
7
b
of the first carrying section
7
is positioned at the first processing section K, and the second clamping section
7
b
re-clamps the electric wire W.
Next, the first carrying section
7
moves in the arrow mark n direction, and the second clamping section
7
b
moves to the second processing position L.
Next, the clamping section
9
a
of the third carrying section
9
re-clamps the electric wire W, and the third carrying section
9
moves in the arrow mark q direction to move the electric wire W to a position near the terminal crimping section
6
E.
Next, a terminal is crimped to the other end terminal of the electric wire W by the terminal crimping section
6
E, and thereafter the third carrying section
9
returns to the original position.
Next, the third clamping section
7
c
of the first carrying section
7
is positioned at the second processing position L, and the third clamping section
7
c
re-clamps the electric wire W.
Next, the first carrying section
7
moves in the arrow mark n direction to move the third clamping section
7
c
to the third processing position M.
Then, the clamping section
6
F re-clamps the electric wire W, and the electric wire W is moved to the fourth processing position N by the move of the first carrying section
7
, and the electric wire W is exhausted by the wire exhausting section
6
G. Thus, the terminal processing at the other end side of the electric wire W also finishes.
According to the above-described apparatus
1
, however, it is necessary to use a worm gear, a worm wheel, a belt, etc. as a mechanism for turn driving the turning arm
4
. It is generally difficult to accurately position the turning arm
4
at each position of H, I and J, because of the backlash generated between the worm gear and the worm wheel at the time of stopping the turning arm
4
at each position of H, I and J. Particularly, the move volume of the head portion
4
a
at the front end of the turning arm
4
becomes large, and thus, it is considered difficult to secure a constant level of processing quality at each position of H, I and J.
With a view to solving the above-described problems, it is an object of the present invention to provide an automatic cutting
