Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an intermediate assembly device for a controller used for electronic control of fuel injection of an automobile engine, and more particularly to a shield case of the controller. The present invention relates to a forming jig device that bends an electric wire (lead wire) of a plurality of capacitors so as to have a predetermined shape when the capacitors are penetrated and attached.

(Prior Art) As a jig device for forming a feedthrough capacitor in order to obtain an intermediate product of a controller for controlling electrical components of an engine, conventionally, a jig device was manually operated to obtain an intended intermediate product. The method using the conventional apparatus will be described below in the order of steps with reference to FIG. As shown in FIG. 3 (a), four capacitors 2 (which may be any number) are attached to the side wall of the case (work) 1 with a bottom plate so as to pass through the side wall of the case 2 and both sides of the capacitor 2. Electric wire 3 to be the lead wire
Is prominent, and it is a proposition that the long, inner wire is bent at a right angle to face upward. Therefore, first, as shown in (b), a jig (B) 5 having the same number of grooves 4 into which the electric wires 3 are inserted is prepared. On both sides of the lower portion of the jig (B) 5, there are guide plates 6 that horizontally project. Next, as shown in (C), a jig (A) 8 having a plurality of triangular thin plates 7 for bending the electric wire 3 is prepared. Then, as shown in (d), the jig (B) 5 is inserted along the left inner wall of the work 1 of (a) and inserted into the groove 4 in the electric wire 3, and the jig (A) 8 is inserted along the right inner wall. . Next, as shown in (e), the jig (A) 8 is horizontally moved by hand as indicated by an arrow X, and then the tip 7a of the thin plate 7 is rotated around the center. This way,
First, the horizontal movement causes the electric wire 3 of the capacitor 2 to bend at an angle α of about 60 ° as shown in (f), and at the next rotation (g)
As shown in, the angle β is about 90 °. In this way, conventionally, the forming of the feedthrough capacitor has been performed manually.

(Problems to be solved by the invention) However, since such a conventional one is formed by hand as described above, the forming angle is not constant depending on the person (worker), and the subsequent assembly work is difficult. There was a problem that it would have a bad influence, and that it would take man hours to correct it. The present invention solves the above-mentioned problems by providing a forming device for a feedthrough capacitor, which mechanically performs the forming work automatically and does not adversely affect the subsequent assembling work, and does not require man-hours. It is an object.

[Means for Solving the Problems] (Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention provides a work base for mounting a shield case having a plurality of capacitors penetrating therethrough and a wire for bending the capacitor. A jig A having a plurality of triangular thin plates, a jig B having a plurality of grooves for holding the electric wire when the jig A is bent by the thin plates entering, a base for fixing the jig B, and the work. A first cylinder that operates to combine the base and the jig B;
Jig A for the combination of the work base and jig
And a second cylinder that is operated so as to rotate after that.

(Operation) When the worker sets the work on the work base and presses the operation button, the work cylinder is lifted and combined with the jig (B) fixed to the base by the first cylinder. Then, by the second cylinder, the jig (A) comes close to this combination, first makes an intermediate bend, and then rotates and bends at a right angle. The mechanical work of such a jig makes the bending angle constant.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. First, the configuration will be described. The work 1, the jig (B) 5 and the jig (A) 8 are the same as the conventional ones, but in this embodiment,
It is an important point that they are arranged so that they are related to each other. Therefore, FIG. 3 of the conventional drawing will be referred to as necessary.

The table 10 is fixed to the floor, and the jig (B5 is fixed to the table 10 by the bracket 11. The work base 12 is shown in FIG. 1 (b) (this figure shows the work base from FIG. 1 (a)). 12 and the work 1 are lowered and only this is taken out.)
The work 1 is attached to and is held by the work holder 13. Work base 12 is stand 1
It is possible to move up and down with respect to the base 10 by the cylinder 14 for moving up and down. This work base 12 is shown in FIG.
Shows a state in which the jig (B) 5 and the work 1 are combined with each other. As can be seen by referring to FIG. 2, the jig (A)
8 is connected to the shaft 16a of the second forming cylinder 16 via a bracket 15 by a pin 17, and a bearing 18 supported by the bracket 15 allows the work base 8 to be supported.
The bearing 18 rolls on a guide 20 which is integral with the unit 12 to perform a predetermined movement. The forming cylinder 16 is supported at its left end by a bracket 21 on the base 10 via a pin 19 so that the pin 19 serves as a tilt fulcrum.
Further, the right side is supported by the bracket 22 so as to be tiltable. Then, by attaching one end of the spring 23 to the right end of the cylinder 16, the right side of the cylinder 16 is always pulled in the direction of the table 10 to which the other end of the spring 23 is attached.

Next, the operation of the above embodiment will be described. When the work 1 is set on the work base 12 and the button on the control panel (not shown) is pressed, the work cylinder is lifted to raise the work base.
12. Work 1 rises, jig (B) 5 and work 1 are combined, and rise stops. As described above, the combined state is shown in FIG. 1 (a), and the separated state is shown in FIG. 2 by the solid line, and the work 1 in the combined or raised state is shown.
And the work base 12 is shown in phantom. After this ascending step, the forming cylinder 16 operates and the shaft 16a retracts. The bracket 15 connected to the shaft 16a by the pin 17, and thus the jig (A) 8 approaches the jig (B) 5 and the work 1, and the thin plate 7 enters the groove 4. In this case the bearing
18 rolls on a guide 20 integrated with the work base 12 and is guided. The state where the approach is completed is the same as the intermediate bending state shown in FIG. 3 (f). When the shaft 16a is further retracted by the subsequent operation of the forming cylinder 16, the jig (A)
As a result that the leading end 7a of the thin plate 7 of 8 is stopped by the groove 4 of the jig (B) 5 (see the leading end 7a portion in FIG. 3C), the jig (A) 8 rotates about this leading end as a fulcrum. To do. Therefore, the bracket 15 of the jig (A) 8 also rotates and becomes in the state of the chain line (see FIG. 2). In this case, because of the tensile force of the spring 23,
The bearing 18 is on the guide 20 and ensures the movement of the jig (A) 8. The movement of such a jig (8) is
As shown by an arrow Y in FIG. 2, it is the same as the conventional one, that is, the arrow X in FIG. 3, but since the one according to this embodiment is mechanically performed, the bending angle is smaller than that of the conventional one. It can be said to be constant.

In addition, in the above-described embodiment, the forming form is described as the horizontal holding forming, but the invention is not limited to this, and for example, the vertical holding forming may be used.

[Effect of the Invention] As described above, according to the present invention, the variation in the forming angle due to the difference in the workers is eliminated, and there is an effect that the subsequent work is not adversely affected.
