Description

Technical Field

[0001] This utility model relates to the field of electrode cylinder positioning technology, and more specifically, to an electrode correction and positioning mold. Background Technology

[0002] Due to transportation and the inherent structure of the electrode cylinder, it is prone to deformation; in particular, the longitudinal rib structure of the cylinder may exacerbate local deformation due to stress concentration, and the roundness accuracy of the electrode cylinder directly affects the subsequent welding quality. Existing straightening molds typically employ a rigid, fixed structure, applying radial pressure to the electrode cylinder using mechanical rollers to correct deformation. However, this approach has the following problems:

[0003] If there is a positional deviation during the lifting and lowering process of the electrode cylinder, it is easy to interfere with the rigid positioning structure, resulting in a decrease in correction accuracy or even secondary damage.

[0004] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a convenient and highly accurate electrode correction and positioning mold is provided.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An electrode correction and positioning mold includes a mounting platform, a positioning ring, and a correction wheel assembly. The correction wheel assembly is provided with several units and is evenly distributed along the circumference of the positioning ring. Each correction wheel assembly includes two positioning wheel frames correspondingly arranged on the upper and lower sides of the positioning ring. Positioning wheels are rotatably arranged on the positioning wheel frames.

[0008] The mounting platform has holes in the middle for electrodes to pass through from the top and bottom. Three connecting seats are fixedly connected to the upper end of the mounting platform. Three hinge seats are evenly distributed around the outer side of the positioning ring. The three hinge seats correspond one-to-one with the three connecting seats. The hinge seats and the corresponding connecting seats are connected by connecting rods. The two ends of the connecting rods are respectively ball-hinged with the hinge seats and the connecting seats.

[0009] Preferably, the lower positioning wheel frame of one of the straightening wheel sets is replaced with an encoder assembly. The encoder assembly includes a mounting plate, a connecting plate, and an encoder. The mounting plate is fixedly installed at the lower end of the mounting platform. One end of the connecting plate is hinged to the mounting plate, and the other end of the connecting plate is connected to the mounting plate by a spring.

[0010] The encoder is fixedly mounted on the connection plate.

[0011] Preferably, the connecting rod includes a threaded rod and two fisheye bearings threaded to both ends of the threaded rod, and a locking nut is provided on the threaded rod.

[0012] Preferably, the positioning ring has an H-shaped cross-section, and multiple reinforcing plates are provided between the inner and outer ring surfaces of the positioning ring.

[0013] Preferably, the positioning wheel frame includes a base plate and a mounting base fixedly connected to the base plate. The base plate is connected to the positioning ring by bolts, and the positioning wheel is rotatably mounted on the mounting base.

[0014] Preferably, the rotary drive component is an electric motor or a pneumatic motor.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] This invention connects the positioning ring and the mounting platform via three sets of ball joints, allowing the positioning ring to float within a small range during electrode lifting and lowering, avoiding rigid collisions caused by positional deviations and improving the safety and accuracy of the correction process. A V-shaped positioning wheel assembly with symmetrical upper and lower sections achieves bidirectional constraint through the cooperation of the wheel grooves and electrode ribs, enhancing the correction effect on electrode cylinder deformation while reducing contact damage to the electrode surface. The H-shaped cross-section positioning ring, combined with a reinforcing plate design, significantly improves the overall structural strength; the split positioning wheel frame is bolted together, facilitating individual replacement or maintenance and reducing long-term operating costs.

Three hinge seats 21 are evenly distributed circumferentially on the outer side of the positioning ring 2, each corresponding to one of the three connecting seats 12. The hinge seats 21 and their corresponding connecting seats 12 are connected by a connecting rod 22, with both ends of the connecting rod 22 ball-jointed to the hinge seats 21 and the connecting seats 12, respectively. By setting the connecting rod 22, the positioning ring 2 can move within a small range, preventing interference with the positioning ring 2 due to errors during electrode lifting and lowering, thus affecting the correction accuracy of the electrode correction.

The electrodes are straightened by the cooperation of the straightening wheel sets at preset positions with the ribs on the electrode cylinder. Each straightening wheel set includes two positioning wheel frames 3 corresponding to the upper and lower sides of the positioning ring 2. Positioning wheels 31 are rotatably mounted on the positioning wheel frames 3. The positioning wheels 31 are V-shaped wheels. The electrode cylinder is straightened by inserting the ribs into the grooves of the upper and lower positioning wheels 31.

[0028] Preferably, the connecting rod 22 includes a threaded rod 24 and two fisheye bearings 25 threaded to both ends of the threaded rod 24. A locking nut 26 is provided on the threaded rod 24. By rotating the threaded rod 24, the working length of the connecting rod 22 can be adjusted. By locking the locking nut 26 against the fisheye bearings 25, the length of the connecting rod 22 can be locked.

[0029] To ensure the structural strength of the positioning ring 2, the cross-section of the positioning ring 2 is H-shaped, and multiple reinforcing plates 23 are provided between the inner and outer ring surfaces of the positioning ring 2.

One end of the connecting plate 42 is hinged to the mounting plate 41, and the other end of the connecting plate 42 is connected to the mounting plate 41 through a spring 45. The encoder 43 is fixedly installed on the connecting plate 42. The connecting plate 42 is tightened by the spring 45 so that the encoder 43 can reliably contact the electrode cylinder for monitoring the descent height of the electrode cylinder.

[0032] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
