Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-baking electrode welding manufacturing technology, specifically to a rib alignment and clamping device for welding self-baking electrode cylinders. Background Technology
[0002] Self-baking electrodes consist of an electrode cylinder and electrode paste added to the electrode cylinder. During the calcium carbide furnace production process, the electrode paste below the conductive clip is baked into a mature carbon electrode by resistance heating, conduction heating and radiation heating, and is continuously consumed under the action of the end arc. It is necessary to continuously weld electrode cylinders to the upper part of the electrode cylinder and continuously add electrode paste to the electrode cylinder to form a self-baking electrode for continuous production.
[0003] The electrode cylinder is a hollow cylindrical tube with multiple ribs evenly distributed on its outer cylindrical surface. When welding the electrode cylinder to the upper part of the electrode cylinder, it is necessary to ensure that the outer cylindrical surfaces of the two electrode cylinders are aligned and the ribs are aligned before welding can proceed. Currently, workers manually align and clamp the ribs using hand clamping tools. This manual operation is time-consuming, labor-intensive, and cannot achieve fast and effective alignment and clamping. Therefore, designing and manufacturing a rib alignment and clamping device specifically for welding self-baking electrode cylinders, which can automatically perform the alignment and clamping operation and improve welding efficiency, is a very meaningful endeavor. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a rib alignment and clamping device specifically for welding self-baking electrode cylinders. This device features a novel structure and practical function, enabling automated alignment and clamping of the electrode cylinder's ribs. It ensures accurate alignment and secure clamping, thereby improving welding efficiency and quality.

The inner side of the main clamping block 1 is provided with an arc-shaped clamping concave surface 11. A horizontal groove 12 and a vertical groove 13 are provided in the middle of the main clamping block 1. Clamping planes are respectively provided on the left side of the main clamping block 1 and the right side of the vertical groove 13. Two auxiliary clamping blocks 2 are respectively arranged corresponding to the clamping plane on the left side of the main clamping block 1 and the clamping plane on the right side of the vertical groove 13. Connecting arms 21 are provided on the upper and lower sides of the clamping block 2. The connecting arms 21 are V-shaped and are provided with end hinge pins 22 and middle hinge pins 23.

The cylinder body of the clamping power cylinder 3 is hinged to the main clamping block 1, and the piston rod of the clamping power cylinder 3 is hinged to the middle hinge pin 23. The connecting rod 4 is provided between the two auxiliary clamping blocks 2, and the two ends of the connecting rod 4 are respectively hinged to the middle hinge pins 23 on the two auxiliary clamping blocks 2.
[0006] A further improvement is that the connecting rod 4 includes a middle connecting rod 41 and an end hinge rod 42. The two end hinge rods 42 are respectively arranged at both ends of the middle connecting rod 41. The two ends of the middle connecting rod 41 have threaded holes. One end of the end hinge rod 42 is provided with a threaded rod, and the other end is provided with a hinge hole. The threaded rod of the end hinge rod 42 is threadedly connected to the threaded hole of the middle connecting rod 41, and the hinge hole of the end hinge rod 42 is hingedly connected to the middle hinge pin 23.

[0015] like Figures 1 to 5As shown, a rib alignment clamping device specifically for self-baking electrode cylinder welding includes a main clamping block 1, auxiliary clamping blocks 2, a clamping power cylinder 3, and connecting rods 4. The inner side of the main clamping block 1 has an arc-shaped clamping concave surface 11 that contacts the outer cylindrical surface of the electrode cylinder. A horizontal groove 12 and a vertical groove 13 are provided in the middle of the main clamping block 1. Clamping planes are provided on the left side of the main clamping block 1 and the right side of the vertical groove 13, respectively, contacting one side of the rib. Two auxiliary clamping blocks 2 are respectively positioned corresponding to the clamping planes on the left and right sides of the main clamping block 1 and the vertical groove 13, respectively. Connecting arms 21 are provided on the upper and lower sides of the auxiliary clamping blocks 2. The connecting arms 21 are V-shaped and have end hinge pins 22 and middle hinge pins 23. The two auxiliary clamping blocks 2 are hinged to the main clamping block 1 via end hinge pins 22. The cylinder body of the clamping power cylinder 3 is hinged to the main clamping block 1, clamping... The piston rod of the power cylinder 3 is hinged to the middle hinge pin 23 on the auxiliary clamping block 2, which is correspondingly set on the clamping plane on the left side of the main clamping block 1. The connecting rod 4 is set between the two auxiliary clamping blocks 2. The two ends of the connecting rod 4 are respectively hinged to the middle hinge pin 23 on the two auxiliary clamping blocks 2. The connecting rod 4 includes a middle connecting rod 41 and an end hinge rod 42. The two end hinge rods 42 are respectively set at the two ends of the middle connecting rod 41. The two ends of the middle connecting rod 41 have threaded holes. One end of the end hinge rod 42 has a threaded rod and the other end has a hinge hole. The threaded rod of the end hinge rod 42 is threadedly connected to the threaded hole of the middle connecting rod 41. The hinge hole of the end hinge rod 42 is hinged to the middle hinge pin 23. A fastening nut 43 is set on the threaded rod of the end hinge rod 42. Rotating the end hinge rod 42 can adjust the connection length of the connecting rod 4. The fastening nut 43 plays a role in tightening and fixing the end hinge rod 42.
[0016] The concave surface 11 of the arc clamping mechanism contacts the outer cylindrical surface of the electrode cylinder. The clamping plane on the left side of the main clamping block 1 and the clamping plane on the right side of the vertical groove 13 contact one side of the convex rib, which can align the convex rib. The piston rod of the clamping power cylinder 3 is pushed out, which pushes the two auxiliary clamping blocks 2 to rotate, so that the two auxiliary clamping blocks 2 clamp the convex rib with the clamping plane on the left side of the main clamping block 1 and the clamping plane on the right side of the vertical groove 13, respectively. The automated alignment and clamping operation is accurate and the clamping is firm, which is conducive to improving welding efficiency and welding quality.
