Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for continuously slotting grooves in the lower end of headed terminals used in electrical equipment and the like.

It was common knowledge that when using conventional slotting devices to cut a slot into a screw head or terminal end, the workpiece was temporarily fixed and still, and then the slotting process was performed. Since the number of processes per hour is low, the cost is high, and since the bottom of the slit groove is formed in an arc shape, it has the disadvantage that it cannot be properly abutted against the driver.

In view of the above-mentioned drawbacks, the present invention provides an apparatus capable of performing slot splitting while continuously conveying the workpiece without temporarily fixing it at rest.

Below, one embodiment of the slotting device according to the present invention will be explained according to the drawings. Fig. 1 shows a headed terminal in which the lower end of the terminal is slotted using the slotting device according to the present invention. This is a terminal A for electrical equipment in the shape of a truncated cone with an outer diameter larger than the diameter.

As shown in Fig. 2, the slitting machine equipped with this device has a parts feeder 2 and a feeding chute 11 on the right side of the machine stand 1, and opposite to this on the left side of the machine stand 1. The reducer 3 is installed so that the slit device 8 faces diagonally upward.
is erected, and the rotating shaft of the slotting device 8 is fixedly connected to the output shaft thereof, and on the right side of the slotting device 8 so as to be adjustable on the extension surface of the plane of the rotating disk 14 of the slotting device 8. Fixed cutters 7 are arranged in parallel.

Furthermore, to explain the drive system mechanism of the reduction gear 3 and the fixed cutter 7, a dogleg-shaped motor 4 is installed on the machine stand 1 at the back of the reduction gear 3, and the slitting device 8 is rotated on the back side. The motor 5 necessary for This is a mechanism in which the slitting device 8 is driven by.

Further, a motor 6 necessary for rotating a cutter 7 and a rotary brush 9 disposed at the head of the slitting device via a pulley and a belt is screwed onto the top surface of each motor 4.

Next, a discharge chute 12 for discharging the terminal A whose slotted groove has been cut is disposed on the left front side of the slotting device 8, and a discharge chute 12 for discharging the cutting powder produced by the cutting of the cutter 7 is disposed on the front left side of the slotting device 8. shoe) 10 are arranged to constitute a slitting machine equipped with a slitting device.

To explain the slit device 8 in detail with reference to FIGS. 3, 4, and 5, the rotating shaft of the rotary disk 14 is fitted with the output shaft of the reducer 3, which is disposed slightly upward, by tapered fitting. A plurality of triangular grooves 20 are equally divided into a plurality of triangular grooves 20 for accommodating and transporting the diameter portion of the terminal A on the outer peripheral edge 16 of the rotating disk 14.

The angle of the triangular groove 20 is limited to an angle of 55° to 60°.

Inside the outer circumferential edge 16, a ring 15 is screwed to the inner plate 14 with bolts to form a ring 19 having a width equal to or slightly larger than the head for housing the terminal head. There is.

The disc 14 is arranged between the lower flange 21 and the upper flange 13, the lower flange 21 is screwed onto the upper surface of the reducer 3, and the upper flange 13 is separated from the disc 14 by three spacers 22. Adjust the lower flange 21 with bolts.
It is attached to and screwed with three nuts 24.

Therefore, a small gap should be formed between the terminal diameter part and the lower surface of the upper flange 13 so that the terminal A does not move due to cutting force when the terminal diameter part is housed in the triangular groove 20 on the outer peripheral edge 16 of the disk 14. I can do it.

The upper flange 13 has a notched ring shape extending 270° from the right side of the terminal feed chute 11 to the top of the terminal discharge chute 12, and the inner diameter is equal to the position below the head and neck of the terminal A, that is, the circumference of the round circle 19, and the outer diameter is The fasteners have a large outer periphery so as to have enough space to tighten the nuts 1 to 24.

Further, the outer periphery of the portion where the cutter 7 and rotating flange 9 are disposed is formed into a straight line.

The cutter 7 is on the same plane as the center line of the disc 14, and the rotary brush 9 is suspended above the center line of the upper flange 13 by a support arm 23 whose angle can be freely changed from the lower flange 21.

The final end of the upper flange 13 is on the extension of the center line of the disc 14 and the cutter 7, the terminal discharge chute 12 is attached in contact with the final end of the upper flange 13, and the upper left bent piece 25 is It is bent upward, and the tip of the terminal end support plate 18 is screwed diagonally upward so that the tip of the terminal end support plate 18 approaches the outer periphery of the disk outer peripheral edge 16. The pieces 17 are arranged next to each other, and their tips are formed at an acute angle (approximately 30 degrees), and are inserted close to the bottom surfaces of both terminal head insertion grooves 19 of the disc 14.

Next, to explain the operation of the above structure according to the present invention, the terminals A whose heads are aligned upward by the parts feeder duff* are sent to the terminal feeding shoe 1 via 11 to the outer peripheral edge of the disk 14 of the slotting device 8. The diameter portion of the terminal is accommodated in the triangular grooves 20 equally divided into the terminals 16, and the head enters the terminal head insertion grooves 19 upward and is moved upward by the counterclockwise rotation of the disc 14 until it is near the horizontal line. A groove is slotted at the lower end of the terminal by the cutter 7.

Since the terminal A is slotted while being transported, and since the cutter 7 is fixed, the bottom of the cutting groove at the end of the terminal is cut linearly, and the diameter of the terminal is cut from 55° to 60° of the triangular groove 20. Since it is supported by the two acute-angled sides of ', and the lower surface of the neck of the terminal head is supported and fixed by the rounded side surface 19 of the outer peripheral edge 16, it will not vibrate or become misaligned due to the rotational force of the cutter. .

When the slotted terminal is transferred to the top of the slotting device 8, a small amount of debris remaining in the slotting groove is removed by the rotating flange 9, and the terminal head is placed at the left end of the center horizontal position of the slotting device 8. Since the acute-angled head of the terminal head raising piece 17 is inserted into both insertion grooves 19 close to the bottom surface of the groove, when the terminal head is raised and facing upward, the terminal end support plate 18
The lower end surface of the terminal A is supported by the end of the terminal A as a fulcrum, and the terminal A can freely fall into the discharge chute 12 by lever action.

Although one embodiment of the slotting device of the present invention has been described above, it is also possible to slot not only head terminals but also tapping screws, etc., and the cost can be reduced because the number of manufactured items increases because grooves are processed while being transported. At the same time, there is an effect that it is possible to manufacture a terminal in which the bottom of the slotted groove is machined into a straight line.
