Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic tapping device for terminal fittings used in relay terminal blocks for electrical wiring. The terminal fitting used for the terminal block has a screw hole into which a terminal screw is screwed in the center of the flat plate portion. The present invention is a device for automatically raising the screw hole. .

[0002]

[Prior art]

 In the past, terminal fittings differed in shape and size, making automatic tapping difficult, and most tapping machines were operated directly by the operator. Of course, there was an automatic tapping device as shown in Utility Model Publication (Sho 62-28341).

The automatic tapping device reciprocates the feed claws in the left and right directions by an air cylinder that operates in synchronization with the vertical movement of the spindle of the tapping machine, and intermittently makes a pitch for each hole in the workpiece. It was combined with an intermittent feeding device that transfers directly below the tap.

However, the automatic tapping device according to the utility model automatically transfers the terminal block base on which the terminal fitting for tapping is mounted by the feed claw having a special shape matching the terminal block base by the pitch. However, it could not be used for making a screw hole using only the terminal fitting.

[0005]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide an automatic tapping device in which only the terminal fittings are sequentially and continuously transferred without being attached to the terminal base, and the intermittent transfer control for the pitch can be easily performed.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is arranged such that a terminal fitting having a temporary screw hole is transferred above a terminal feeding rail for transferring the temporary screw hole while aligning the temporary screw hole on the upper surface side. Install a tapping machine that taps into the temporary screw hole, and insert it into the temporary screw hole of the terminal fitting from above, above the terminal feed rail upstream of the tapping machine, and at a pitch that matches the width of one terminal fitting. Install an intermittent feeding device that has feed pins formed to move the terminal fittings to the tapping machine side.Stop the terminal fittings on the terminal feeding rail downstream from the tapping machine at a position that matches the pitch of the terminal fittings, and also intermittently. Provided an automatic tapping device for terminal fittings, which is equipped with a terminal retainer that is urged against the terminal fittings so that the stopping force is released by the driving force of the feeder. It is an do.

【Example】

 A description will be given below according to the illustrated embodiment. FIG. 1 is an overall front view of an automatic tapping device according to the present invention. The automatic tapping device includes a terminal fitting supply device 1, a terminal feed rail 2, an intermittent feed device 3, a tapping machine 4, and a terminal retainer 5. And a terminal metal fitting receiving rail 6.

The terminal metal fitting supply device 1 supplies the terminal metal fittings to the terminal feed rail 2 from the ball 7 in which a large number of terminal metal fittings are accommodated, via a track formed in the ball 7, a terminal metal fitting alignment mechanism and the like. The terminal metal is conveyed by vibration.

The terminal feeding rail 2 is a rail for transferring the terminal fitting A from the terminal fitting supply device 1 to the tapping machine 4, and automatically from the terminal fitting supply device 1 side to near the tapping machine 4. Although it is inclined so as to be transferred, it is installed horizontally near the tapping machine 4 because forced transfer is performed by the intermittent feeding device 3. On the terminal feed rail 2, the terminal fitting A is transferred with the horizontal surface portion to be tapped up. In addition, a temporary screw hole B (only a hole is provided and not tapped) is already formed on the horizontal surface of the terminal fitting A.

The tapping machine 4 is installed above the terminal feed rail 2 at a position where the tap 9 can be tapped into the provisional screw hole B by descending the tap 9. The tapping machine 4 is a normal tapping machine and need not be unique to the present invention. A cooling oil supply pipe 11 is installed near the tap 9 of the tapping machine 4.

An intermittent feeding device 3 formed with a feed pin 10 for inserting the provisional screw hole B of the terminal fitting A from above to feed the terminal fitting A above the terminal feeding rail 2 upstream of the tapping machine 4. Is installed. The intermittent feeding device 3 is composed of a drive unit 31, an operating arm 32 extending from the drive unit 31 and a feed pin 10 formed at the tip of the operation arm 32, and the feed pin 10 is one terminal. It has the role of transferring the terminal metal fittings to the tapping machine 4 side at a pitch that matches the width of the metal fittings, and the operation procedure is shown in order from FIG. 5 to FIG.

The operation of the feed pin 10 will be described with reference to FIG. In FIG. 5, the tapping work of the terminal fitting A3 just below the tap 9 is completed, and the tap 9 is lifted. At this time, the feed pin 10 descends and descends with respect to the two upstream terminal fittings A5, and the tip of the feed pin 10 is inserted into the temporary screw hole of the terminal fitting A5. Then, as shown in FIG. 6, the feed pin 10 transfers one terminal metal fitting A5 to the tapping machine 4 side while the tap 9 is standing by upward. At this time, the temporary screw hole of the terminal fitting A4 is located immediately below the tap 9. The arrows shown in the figure indicate the operating directions of the tap 9 and the feed pin 10.

Subsequently, the tap 9 descends and while the tapping work is performed on the terminal fitting A4, the feed pin 10 rises as shown in FIG. 7, and one terminal fitting as shown in FIG. Retreat as much as possible and position it right above the temporary screw hole of the next terminal fitting A6. By repeating this operation, the intermittent feeding operation is continuously performed.

Downstream of the tapping machine 4 of the terminal feeding rail 2, the terminal fitting is stopped at a position adapted to the pitch of the terminal fitting, and the stopping force is released by the driving force of the intermittent feeding device 3. The terminal retainer 5 which is biased against the terminal fitting is installed in the. In the illustrated embodiment, the terminal retainer 5 is provided with a separately-installed mount 51, a retainer arm 52 extending from the mount 51 to the terminal feed rail 2 side, and a retainer ball 53 attached to the tip of the retainer arm 52, as shown in FIG. The holding ball 53 holds down the screwed terminal fitting A1 in FIG.

Reference numeral 12 in the drawing denotes an air blowing pipe for forcibly blowing the terminal from the terminal feeding rail 2 at the end of the terminal feeding rail 2 and dropping it into the terminal metal receiving rail 6.

[Effect of device]

 As described above, the present invention installs an intermittent feeding device in which a feed pin inserted into a temporary screw hole of a terminal fitting and moved at a predetermined pitch is formed upstream of the tapping machine, and downstream of the tapping machine of a terminal feeding rail. Install the terminal retainer that is urged against the terminal fitting so that the terminal fitting is stopped at a position that matches the pitch of the terminal fitting and the stopping force is released by the driving force of the intermittent feeding device. As a result, the screwing of the terminal metal fittings can be performed sequentially without using the terminal base, only with the terminal metal fittings, and intermittent transfer control for the pitch can be easily performed.
