Description

Technical Field

[0001] This invention belongs to the field of graphite electrode connector technology, specifically referring to a graphite electrode connector assembly device. Background Technology

[0002] Graphite electrodes are high-temperature resistant graphitic conductive materials made from petroleum coke and pitch coke as aggregates and coal tar pitch as a binder. The process involves calcination, crushing and grinding, batching, mixing, molding, roasting, impregnation, graphitization, and machining of the raw materials. Graphite electrodes are typically cylindrical, and a special connector is used to connect two electrodes. The connector surface is machined with male threads, and both ends of the electrode have threaded holes that mesh with the connector threads. This connection method can be further divided into cylindrical connector connections and conical connector connections. The conical connector uses tapered threads... Compared to traditional cylindrical threads, the mating of graphite electrodes requires higher precision. It is necessary to ensure that the tapered thread is centered and to avoid mis-threading. Tightening is required after the male and female threads have made smooth contact. Currently, graphite electrodes are usually manually aligned and tightened by hoisting during assembly, which results in lower precision. At the same time, in order to ensure the conductivity of the motor and to ensure a tight fit between the electrode and the connector, electrode connector adhesive needs to be applied between the electrode and the connector during assembly. The traditional method is usually manual application, which makes it difficult to evenly fill the space between the connector and the electrode, thus reducing the conductivity of the graphite electrode. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a graphite electrode connector assembly device that can assist in aligning the electrode connectors during assembly and automatically apply connector adhesive during the assembly process.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a graphite electrode connector assembly device, including a base and a rotating ring. The rotating ring is rotatably mounted on the base and can be electrically controlled to rotate. A calibration mechanism is symmetrically provided on the rotating ring. The base is cylindrical.

[0005] Furthermore, the calibration mechanism includes a telescopic rod, which is electrically controlled. An adjustment rod is provided on the top side wall of the telescopic rod, which extends toward the axis of the rotating ring. An adjustment rod is slidably provided at the end of the adjustment rod, and a feeding mechanism is provided at the top of the telescopic rod.

[0006] Furthermore, the adjusting rod includes a sleeve and an inner rod. The inner rod is slidably disposed inside the sleeve. A spring is provided between the inner rod and the sleeve. A U-shaped bracket is provided at the end of the inner rod. A slider is symmetrically disposed inside the U-shaped bracket. The slider is rotatably disposed.

[0007] Furthermore, the adjusting rod includes a rod body and a support bar. The support bar is located on the side of the rod body near the axis of the rotating ring. The thickness of the support bar gradually decreases from top to bottom. The side wall of the rod body has symmetrically opened sliding grooves. The slider is slidably disposed in the sliding grooves and fits against the sliding grooves.

[0008] Furthermore, a second sliding groove is provided on the side of the bottom end of the rod away from the support bar. An adjusting block is slidably provided in the second sliding groove. The adjusting block includes a second slider and a convex shaft. The second slider is slidably provided in the second sliding groove and fits against the second sliding groove. The convex shaft is provided on the side wall of the second slider and extends outward. A second spring is provided in the second sliding groove, and the second spring connects the second sliding groove and the second slider.

[0009] Furthermore, the rod body is provided with a feeding pipe, the top of the rod body is provided with a connector, the connector is connected to the feeding pipe, and the side wall of the rod body is provided with a linear array of discharge holes, which are connected to the feeding pipe.

[0010] Furthermore, a connecting hose is provided between the feeding mechanism and the connector, and the connecting hose connects the connector and the feeding mechanism.

[0011] Furthermore, a sealing plug is provided on the discharge hole.

[0012] The beneficial effects of the present invention using the above structure are as follows: In the graphite electrode connector assembly device provided by this solution, the graphite electrode is placed inside the base. Then, the telescopic rod is controlled to retract, and the adjusting rod is inserted into the screw hole of the graphite electrode, with the bottom end of the adjusting rod fitting against the angle between the bottom wall and side wall of the screw hole. The electrode connector is then hoisted, its stress relief groove aligned with the adjusting rod, and placed into the screw hole of the graphite electrode. After being compressed by the electrode connector, the side wall of the adjusting rod fits against the female thread, and the support bar contacts the side wall of the electrode connector. Since the thickness of the support bar gradually narrows from top to bottom, the male thread on the electrode connector and the female thread on the graphite electrode do not contact each other under the action of the adjusting rod. Simultaneously, during the process of the adjusting rod side wall fitting against the female thread, the convex shaft is inserted into the thread of the female thread. Then, the rotating ring is controlled to rotate, and the calibration mechanism rotates around the graphite electrode. During this process, the feeding mechanism is activated, and the feeding mechanism delivers the connector adhesive into the feed pipe through the connecting hose. The adhesive is evenly applied to the screw hole through the discharge hole. Simultaneously, during rotation, the convex shaft slides within the female thread, and the adjusting block gradually rises in the second slide groove until it adheres to the top wall of the second slide groove. The adjusting block then supports the adjusting rod. As the calibration mechanism rotates, under the action of the convex shaft and the female thread, the adjusting rod gradually disengages from between the graphite electrode screw hole and the electrode connector. The contact point between the electrode connector thread and the support bar gradually moves downwards, the thickness of the support bar at the contact point gradually decreases, and the distance between the electrode connector and the graphite electrode screw hole gradually decreases until the threads contact each other and are tightened under the rotation of the rotating ring, completing the assembly. This method assists in aligning the electrode connector during installation, ensuring smooth contact between the male and female threads, preventing thread damage. Furthermore, it allows for even application of adhesive within the screw hole during alignment, resulting in more uniform application and higher efficiency. It can also adapt to the slope of tapered threads, flexibly accommodating various specifications of graphite electrodes. Attached Figure Description

[0030] Furthermore, the adjusting rod 7 includes a rod body 701 and a support bar 702. The support bar 702 is located on the side of the rod body 701 near the axis of the rotating ring 2. The thickness of the support bar 702 gradually decreases from top to bottom. The side wall of the rod body 701 has symmetrically opened sliding grooves 703. The slider 505 is slidably disposed in the sliding groove 703 and fits against the sliding groove 703.

[0031] Furthermore, a second groove 704 is provided on the side of the bottom end of the rod 701 away from the support bar 702. An adjusting block 8 is slidably provided in the second groove 704. The adjusting block 8 includes a second slider 801 and a convex shaft 802. The second slider 801 is slidably provided in the second groove 704 and fits against the second groove 704. The convex shaft 802 is provided on the side wall of the second slider 801 and extends outward. A second spring 803 is provided in the second groove 704. The second spring 803 connects the second groove 704 and the second slider 801.

[0032] Furthermore, the rod body 701 is provided with a feeding pipe 705, and the top of the rod body 701 is provided with a connector 706, which is connected to the feeding pipe 705. The side wall of the rod body 701 is provided with a linear array of discharge holes 707, which are connected to the feeding pipe 705.

[0033] Furthermore, a connecting hose 601 is provided between the feeding mechanism 6 and the connector 706, and the connecting hose 601 connects the connector 706 and the feeding mechanism 6.

[0034] Furthermore, a sealing plug 708 is provided on the discharge port 707.

[0035] In practical use, firstly, the graphite electrode is placed inside the base 1. Then, the telescopic rod 4 is retracted, and the adjusting rod 7 is inserted into the screw hole of the graphite electrode. Based on the depth of the screw hole, a portion of the sealing plug 708 is removed from below, and the bottom end of the adjusting rod 7 is aligned with the angle between the bottom and side walls of the screw hole. Next, the electrode connector is hoisted, its stress relief groove is aligned with the adjusting rod 7, and it is placed into the screw hole of the graphite electrode. After being compressed by the electrode connector, the side wall of the adjusting rod 7 is aligned with the female thread, and the support bar 702 contacts the side wall of the electrode connector. Since the thickness of the support bar 702 gradually narrows from top to bottom, the electrode connector 706... The male thread on the graphite electrode and the female thread on the graphite electrode do not contact each other under the support of the adjusting rod 7. Simultaneously, as the side wall of the adjusting rod 7 aligns with the female thread, the convex shaft 802 inserts into the thread of the female thread. Then, the rotating ring 2 is controlled to rotate, and the calibration mechanism 3 rotates around the graphite electrode. During this process, the feeding mechanism 6 is activated, which delivers the connector adhesive into the feeding pipe 705 through the connecting hose 601 and evenly coats it into the threaded hole through the discharge hole 707. Simultaneously, during rotation, the convex shaft 802 slides within the female thread, and the position of the adjusting block 8 in the second slide groove 704 gradually rises until it aligns with the second slide groove 704. 4. After the top wall adjustment block 8 supports the adjustment rod 7 from the slide groove 704, as the calibration mechanism 3 rotates, under the action of the convex shaft 802 and the female thread, the adjustment rod 7 gradually extends outward from between the graphite electrode screw hole and the electrode connector. The contact point between the electrode connector thread and the support bar 702 gradually moves downward, the thickness of the support bar 702 at the contact point gradually decreases, and the distance between the electrode connector and the graphite electrode screw hole gradually decreases until the male thread and the female thread contact each other. After contact, the rotating ring 2 continues to rotate to tighten the electrode connector, completing the assembly. During the tightening process, the convex shaft 802 continues to contact the adjustment rod 7, and the adjustment rod 7 will continue to extend upward. The process continues until the thickness of the adjusting rod 7 in the screw hole is less than the thickness of the stress relief groove. The convex shaft 802 then disengages from the female thread. Subsequently, the telescopic rod 4 is extended to pull out the adjusting rod 7. During this process, the joint adhesive is replenished through the feeding mechanism 6 to fill the stress relief groove. (During the rotation of the rotating ring 2 or the extension of the telescopic rod 4, as the adjusting rod 7 leaves the graphite electrode screw hole, some of the discharge hole 707 will leave the graphite electrode screw hole and discharge some of the joint adhesive outside the screw hole. This part of the joint adhesive can be used as conductive adhesive between the graphite electrodes when assembling another graphite electrode later, without causing waste or pollution.)
