Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a device for pushing and inserting a flat armature coil lead wire into a commutator groove in an electric motor, particularly a flat motor, etc., so that it can be automated and provided at a low cost. It has been made possible.

(Prior Art) The conventional method for temporarily connecting coil lead wires is to insert a jig 20 into the commutator 1 as shown in FIG. This is done by pushing it into the commutator groove 1a as a guide, but this work is done manually using an insertion jig 21. Therefore, in recent years, when performing temporary wiring, as shown in Japanese Patent Application Laid-open No. 53-66502, a coil alignment jig is used in which flat armature coils formed into a predetermined shape are arranged in a ring, and a A temporary wiring device has been proposed, which consists of a wiring jig body equipped in the center so as to surround a commutator, and a temporary wiring board for pushing the coil lead wire into the groove of the commutator, and automation is being promoted.

(Problem to be solved by the invention) However, when attempting automation, this device requires a means for holding the coil lead wire against the connection jig body (lead holding plate) and a means for pushing the held lead wire into the groove of the commutator. A problem arises in that a drive system is required to drive each of the (temporary connection plates), resulting in an expensive product. In addition, a cylindrical auxiliary guide provided on the wiring jig body is fitted onto the outer periphery of the commutator, and annular flat armature coils are arranged around the auxiliary guide, so that the coil array is connected to the commutator by the interposition of the auxiliary guide. There was a problem in that the outer diameter of electric motors such as flat motors became larger as the motor moved away from the flat motor.

Therefore, the purpose of the present invention is to hold the lead wire between a finger-shaped rotating piece and a stop piece, and to eject the lead wire using a slider provided between the finger-shaped rotating piece and the stop piece. The rotating operation of the rotating piece and the sliding operation of the slider are performed by one piston,
This makes it possible to reduce the cost of the device, and also to reduce the outer diameter of the motor by not surrounding the commutator with the main body of the wiring jig.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a coil alignment jig in which flat armature coils formed into a predetermined shape are arranged in a ring, and a commutator is placed in the center thereof;
a connecting jig main body disposed above the coil alignment jig near the commutator; a rotating piece rotatably supported by the jig main body; a stop piece that is fixed in a state facing the child, determines the rotation stop position of the rotary piece, and cooperates with the rotary piece to sandwich the coil lead wire, and a surface of the rotary piece that faces the stop piece; a slider for pushing the coil lead wire, which is slidably disposed on the rotary piece and biased by a spring toward the rotation shaft side of the rotary piece, into the commutator groove; and a slider rotatably supported by the slider. and connected to a piston that slides on the coil alignment jig, and rotates the rotating piece by the pushing action of the piston,
A link is provided for sliding the slider toward the commutator at the tip of the rotating piece.

(Function) According to the present invention, the rotating piece is rotated by pushing out the link connected to the piston, and the coil lead wire is sandwiched between the rotating piece and the stop piece.
Further, the slider slides toward the commutator at the tip of the rotating piece, and the coil lead wire is fitted into the groove of the commutator.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 7, and the configuration will first be explained with reference to FIGS. 1 to 4. In these figures, 1 is a commutator, 2
is a flat armature coil formed into a predetermined shape, 2
Reference numerals a and 2b denote coil lead wires, and 3 a coil alignment jig in which flat armature coils 2 are arranged in a ring shape, and has a plurality of pins 4 on the circumference. Reference numerals 111 and 112 are connection jig bodies disposed on the coil alignment jig 3, and 51 and 52 are rotating pieces rotatably supported by the jig bodies 111 and 112. 81, 82 are shafts 91, 92 fixed to the jig bodies 111, 112.
These stop pieces 81 and 8 are fixed at
2 determines the rotation stop position of the rotating pieces 51, 52, and cooperates with the rotating pieces 51, 52 to sandwich the coil lead wires 2a, 2b. 71 and 72 are sliding bodies inserted through the rotating pieces 51 and 52, and have sliders 71a and 72a that push the coil lead wires 2a and 2b into the commutator groove 1a. Also, the slider 71
a, 72a are arranged on the opposing surfaces of the stop pieces of the rotating pieces 51, 52, and the rotating shafts 61, 6 of the rotating pieces 51, 52
2 side is biased by a spring 121 (see FIG. 3). 161 is a shaft 10 rotatably relative to the sliding body 71.
1, and the link 161 rotates the rotating piece 51 by its pushing action,
The slider 71a is arranged to slide toward the commutator 1 at the tip of the rotating piece 51.

Note that similar links and springs are attached to the sliding body 72 side, and these links are driven by the reciprocating motion of the piston as described later. On the other hand, the coil alignment jig 3 is configured to be rotated by a predetermined angle (not shown), and with this rotation, the commutator 1
It also rotates.

The operation of the embodiment configured as described above will be explained below, but it goes without saying that each component provided in a pair operates in the same way.

Now, FIG. 1 shows the standby state of the rotating piece 51, and the flat armature coil 2 is already attached to the pin 4 of the coil alignment jig 3.
The coil lead wires 2a and 2b are arranged in a ring shape using the commutator 1 as a guide, and the coil lead wires 2a and 2b stand up near the commutator 1.

When the link 161 is driven from this state, the rotating piece 51 rotates in the direction 14a, and then the slider 7
1a slides. This will be explained in principle using FIGS. 5 to 7. FIG. 5 shows the standby state of the rotating piece 51, and at this time, the rotating piece 51 and the slider 7
A piston 171 that rotates and slides 1a is arranged behind the cylinder 181. Further, the slider 71a is urged toward the rotating shaft 61 by the spring 121 and comes into contact with the stopper 19.

When the piston 171 is moved forward in this state, the link 161 is pushed out and the rotating piece 51 rotates until it comes into contact with the stop piece 81. Then, the coil lead wire 2a is inserted between the rotation piece 51 and the stop piece 81.
This state is shown in FIG. 6, where the slider 71
Since a is urged toward the rotation shaft 61 of the rotation piece 51 by the spring 121, it is still in contact with the stopper 19.

Next, when the piston 171 is further moved forward against the force of the spring 121 from the state in which the rotation of the rotary piece 51 is restricted, the slider 71a moves toward the link 161.

slide in the direction. Then, the slider 71a finally discharges the coil lead wire 2a from between the rotating piece 51 and the stop piece 81 as shown in FIG. 7, and inserts the coil lead wire 2a into the groove 1a of the commutator 1. do.

This pushing process is clearly shown in FIG.

Further, when the coil lead wire pushing process is completed, the pushing force of the piston 171 is released, and the rotating piece 51 and the stop piece 81 return to the state shown in FIG. 5. Also, the coil alignment jig 3 is the groove 1a of the commutator 1.
The wire is rotated by a predetermined angle in accordance with the above, and the temporary wire connection process is completed. Then, the above steps are repeated several times to complete the temporary connection.

According to the above embodiment, the rotating piece can be rotated by the pushing action of the link connected to the piston, and the slider can be slid at the same time, so automation can be achieved.
Furthermore, since only one drive system is required for sliding the piston, an inexpensive device can be provided. Furthermore, since there is no cylindrical auxiliary guide provided on the wiring jig body around the commutator on the coil alignment jig, it is possible to bring the commutator and flat armature coil as close as possible. Therefore, the outer diameter of the motor can be reduced.

(Effects of the invention) As described above, in the present invention, the rotating piece can be rotated and the slider can be slid at the same time by the pushing action of the link connected to the piston. The drive system for sliding is 1
Since only one is required, there are advantages such as being able to provide an inexpensive device.
