[0025] Combined with Figure 1-4 The present invention provides a new spot welding conductive automatic adjustment device, comprising: a servo motor 1, a conductive device, a lifting device, a pressure sensor 10, a transmission device, an adjustment device 32, a base plate 22, a spring seat 23, a spring 12, a push rod 11, a conductive head 15, a rocker arm bracket 24, a bearing 26, an axle pin 25, a rocker arm 13, a fixed seat 28, a conductive connecting block 29, and a conductive contact 20; the servo motor 1 is connected to the conductive device and the lifting device respectively, and the lifting device and the adjustment device 32 are connected through the transmission device, wherein the adjustment device 32 is fixedly arranged on the upper end of the base plate 22, the pressure sensor 10 is fixedly arranged on the middle lower end of the base plate 22, the spring seat 23 is fixedly arranged on the upper end of the base plate 22, the position of the spring seat 23 corresponds to the position of the pressure sensor 10, and the spring seat 23 is arranged at the upper end of the pressure sensor 10, the spring 12 is fixedly arranged on the upper end of the spring seat 23, the push rod 11 is arranged in the spring 12, and the conductive head 15 is fixedly arranged on the upper end of the push rod 11.

[0026] To further explain, a rocker arm bracket 24 is fixedly arranged on the side of the base plate 22 away from the adjusting device 32, and a bearing 26 and an axle pin 25 are fixedly arranged on the upper end of the rocker arm bracket 24; the axle pin 25 is inserted into the bearing 26, and the bearing 26 is connected to the rocker arm 13; a fixing seat 28 is arranged on the upper end of the rocker arm 13, and a conductive connecting block 29 is arranged on one side of the fixing seat 28; a conductive contact 20 is fixedly arranged on the upper end of the conductive connecting block 29; and the conductive contact 20 is connected to the conductive device.

[0027] In one embodiment, the conductive device includes: a positive conductive device 2 and a negative conductive device 3; the servo motor 1 is connected to the positive conductive device 2, and a positive pole portion 4 is provided at the upper end of the positive conductive device; a copper nail 5 is connected to the upper end of the positive pole portion 4; a negative pole cover 6 is connected to the upper end of the copper nail 5; a negative pole portion 7 is connected to the upper end of the negative pole cover 6; and the negative pole portion 7 is connected to the negative conductive device 3. The positive pole portion 4 and the negative pole portion 7 can be connected by moving the positive conductive device 2 and the negative conductive device 3 up and down.

[0028] In one embodiment, the lifting device includes: a nut 8, a bolt 9, a motor fixing seat 14, a bearing seat fixing plate 19, and a bearing seat 21; one side of the motor fixing seat 14 is used to fix the servo motor 1, and the other side of the motor fixing seat 14 is fixedly connected to the bearing seat fixing plate 19, the bearing seat 21 is fixedly set at the upper end of the bearing seat fixing plate 19, the nut 8 is set in the bearing seat 21, and the bolt 9 is set in the nut 8. The servo motor 1 drives the nut 8 to rotate by adjustment, and then adjusts the up and down movement of the bolt 9. When the nut 8 rotates clockwise, the bolt 9 moves upward, and when the nut 8 rotates counterclockwise, the bolt 9 moves downward.

[0029] In one embodiment, the transmission device includes: a first synchronous wheel 16, a second synchronous wheel 17, and a synchronous belt 18; the second synchronous wheel 17 is fixedly connected to the bolt 9, one side of the synchronous belt 18 is connected to the second synchronous wheel 17, and the other side is fixedly connected to the first synchronous wheel 16; the first synchronous wheel 16 is fixedly connected to the adjusting device 32, and the adjusting device 32 is provided with an adjustment plate 30 and a screw 31, one end of the screw 31 is fixedly connected to the first synchronous wheel 16, and the other end is fixedly connected to the adjustment plate 30, and the other end of the adjustment plate 30 is fixedly connected to the rocker arm 13.

[0030] To further illustrate, when the conductive contact 20 contacts the conductive head 15, the rocker arm 13 swings downward under the action of the conductive contact 20, and the rocker arm 13 compresses the push rod 11 to move downward, so that the pressure sensor 10 detects the pressure value of the push rod 11. When the pressure value decreases to a certain value, the servo motor 1 rotates to move the rocker arm 13 upward. The servo motor drives the second synchronous wheel 17 to rotate, thereby driving the synchronous belt 18, thereby driving the rotation of the first synchronous wheel 16. The rotation of the first synchronous wheel 16 causes the screw rod 31 to move up and down, thereby driving the height of the adjustment plate 30, realizing the height adjustment of the rocker arm 13, and making the conductive contact 20 contact the conductive head 15.

[0031] To further explain, a first ceramic pad 27 is provided between the bottom plate 22 and the spring seat 23; a second ceramic pad 33 is provided between the rocker arm 13 and the fixing seat 28. The first ceramic pad 27 and the second ceramic pad 33 are provided for protection, and the top rod 11 adopts a piston rod.

[0032] The working principle of the present invention is as follows: the conductive device is driven by the servo motor 1 to make the rocker arm 13 of the conductive device move a certain distance. When working normally, when the conductive contact 20 contacts the conductive head 15, the rocker arm 13 swings downward under the action of the conductive contact 20, and the rocker arm 13 compresses the push rod 11 to move downward. The pressure sensor 10 detects the pressure of the push rod 11 to check whether the conductive contact and the conductive head are in good contact. When the pressure value decreases to a certain value, the servo motor 1 rotates to move the rocker arm 13 upward, so that the conductive contact and the conductive head are in normal contact, thereby realizing the automatic adjustment function.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
