Description

Technical Field

[0002] When the stator is dripping paint, the stator needs to be heated by conductive heating to achieve a gel effect.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As shown in the figure, an embodiment of the present invention discloses a conductive tooling for the stator outgoing pin, including a guiding module 1. The guiding module 1 is provided with a pin guiding hole 101. The guiding module 1 is installed on the first insulating guard plate 2. The first insulating guard plate 2 is installed on one side of the guiding block 3. The other side of the guiding block 3 is installed with the second insulating guard plate 4. A first swing plate 5 is provided on the outer side of the second insulating guard plate 4. A pin 6 is installed at the upper ends of the guiding block 3 and the first insulating guard plate 2. The top of the first swing plate 5 is connected to the pin 6. The first swing plate 5 is connected to the output end of the first cylinder 8 through a connecting pin 7. The first insulating guard plate 2 is connected to the output end of the second cylinder 9. Guide rods 10 are installed at the lower end of the first insulating guard plate 2 and the upper end of the guiding block 3. The guiding block 3 is provided with conduction grooves 301 equal in number to the pin guiding holes 101. Conduction blocks 11 are arranged in the conduction grooves 301. A number of probes 12 are installed in the conduction blocks 11. The probes 12 at the rear end are in contact with the contact points 13, and the probes 12 at the front end are in contact with the outgoing pins 14. The contact points 13 are installed on the guiding block 3. A number of copper plates 15 are installed at the rear end of the guiding block 3. The contact points 13 are electrically connected to the copper plates 15. The copper plates 15 pass through the second insulating guard plate 4 and the first swing plate 5. The conduction blocks 11 are installed with driving rods 16, and one end of the driving rods 16 passes through the first swing plate 5.

[0038] During use, the driving stator or the guiding block 3 drives the overall stator lead pin conductive tooling to move, so that the lead pins 14 of the stator are inserted into the pin guiding holes 101 of the guiding module 1, and then sequentially pass through the first insulating guard plate 2 and enter the guiding block 3, reaching the conduction groove 301. At this time, the lower end of the lead pin 14 does not contact the conduction block 11 and the connection is not completed. At this time, the first cylinder 8 operates to drive the first swing plate 5 to swing, and drives the guiding block 3 to move through the swing. In this way, the guiding block 3 and the conduction groove 3 - 1 clamp the lead pin 14, and the lead pin 14 contacts the probe 12 to complete the electrical connection. The probe 12 is electrically connected to the contact 13. The contact 13 is electrically connected to the copper plate 15, and the copper plate 15 is connected to the power supply to achieve conductive heating.

[0039] The present invention eliminates the traditional manual connection of the lead pins of the stator to the copper plate, and does not require the use of soft wires. The connection of the present invention is firm and can still achieve conductive heating during rotation or lifting. The overall structure is simple and stable.

[0040] The lead pin 14 is electrically connected to the probe 12, and the probe 12 also serves to clamp the lead pin. The lead pin 14 itself does not directly collide with the contact 13 in a straight line, protecting the contact 13. In this way, stable contact can be achieved multiple times, ensuring the service life. If it is designed that the lead pin 14 and the contact 13 are stacked and connected up and down, poor contact will also occur. This is because only when clamping one object can the conduction groove 301 and the conduction block 11 firmly clamp. If two objects are to be clamped up and down between the conduction groove 301 and the conduction block 11, it is easy to slide sideways, and the conductive part of the contact is likely to fall off from the lead pin 14 during rotation, resulting in poor contact.

[0041] The connection links of the present invention are few, the connection points are few, the conduction resistance value is stable, and it does not affect the test results. At the same time, the present invention can be applied to stators of multiple signals.

[0042] In an embodiment of the present invention, the first swing plate 5 is provided with a first moving guiding groove 501, the first insulating guard plate 2 is provided with a first guiding groove 201, the second insulating guard plate 4 is provided with a second guiding groove 401, and the guiding block 3 is provided with a third guiding groove 302. The first guiding groove 201, the second guiding groove 401 and the third guiding groove 302 have the same size. The third guiding groove 302 communicates with the rear end of the conduction groove 301. The driving rod 16 passes through the first moving guiding groove 501, the first guiding groove 201, the second guiding groove 401 and the third guiding groove 302. The first guiding groove 201, the second guiding groove 401 and the third guiding groove 302 are straight grooves. A plurality of limiting clamping plates 17 are provided on both sides of the driving rod 16. The limiting clamping plates 17 play a limiting role to prevent the driving rod 16 from sliding out. The driving rod 16 moves along with the first moving guiding groove 501 and then moves linearly under the constraint of the guiding groove 201, realizing the horizontal movement of the conduction block 11, and realizing clamping and releasing the lead pin 14.

[0043] In an embodiment of the present invention, a clamping groove 111 is provided on one side of the conduction block 11 facing the contact 13. The conduction groove 302 is provided with a protrusion 18 that matches the clamping groove 111.

The 12 contacts 13 are electrically connected to the 3 bronze plates 15. Specifically, the connection manner between the contacts 13 and the bronze plates 15 is determined according to the model of the stator.

[0045] In an embodiment of the present invention, the guiding block 3 is provided with a plurality of wire mounting grooves 303. The contacts 13 and the bronze plates 15 are both arranged at the wire mounting grooves 303, and wires are arranged in the wire mounting grooves, and the wires connect the contacts and the bronze plates.

[0046] In an embodiment of the present invention, the swing plate I 5 is provided with an arc groove 502, and the 3 bronze plates pass through the arc groove.
