[0022] The utility model provides two technical solutions:

[0023] Figure 1-4 The first embodiment is shown: a forging table clamping device for a steering worm gear, comprising a workbench 1, a bearing platform 2 is fixedly connected to the top of the workbench 1, support cylinders 3 are arranged on the top of the workbench 1 and on both sides of the bearing platform 2, the support cylinder 3 on one side is fixedly connected to the workbench 1, and the support cylinder 3 on the other side is slidably connected to the workbench 1, so as to facilitate the adjustment of the position between the two support cylinders 3 and to facilitate the fixing of billets of different lengths, a movable plate 6 is slidably connected to the inner wall of the support cylinder 3, a first spring 7 is fixedly connected to the bottom of the movable plate 6, and the bottom end of the first spring 7 is fixedly connected to the bottom of the inner wall of the support cylinder 3, a non-return mechanism 4 is arranged between the movable plate 6 and the support cylinder 3 to prevent the first spring 7 from rebounding, and the non-return mechanism 4 comprises a mounting cylinder 41, one end of which is fixedly connected to the support cylinder 3, and an adjusting plate 4 is slidably connected to the inner wall of the support cylinder 3 2. One end of the adjusting plate 42 is fixedly connected with a limiting tooth 43, and the end of the limiting tooth 43 away from the adjusting plate 42 passes through the mounting tube 41 and the supporting tube 3 and extends to the inside of the mounting tube 41. One side of the movable plate 6 is fixedly connected with a limiting rack 44 adapted to the limiting tooth 43, and the other side of the adjusting plate 42 is fixedly connected with an adjusting rod 45, and the end of the adjusting rod 45 away from the adjusting plate 42 passes through the mounting tube 41 and extends to the outside of the mounting tube 41. One side of the adjusting plate 42 and the surface of the adjusting rod 45 are fixedly connected with a second spring 46, and the second spring 46 is in a compressed state. The end of the second spring 46 away from the adjusting plate 42 is fixedly connected to the inner wall of the mounting tube 41, and the top of the movable plate 6 is fixedly connected with a supporting rod 8. The top of the supporting rod 8 is provided with a three-jaw chuck 9 through an adjusting mechanism 5, and the adjusting mechanism 5 is used to adjust the angle of the three-jaw chuck 9.

[0024] By setting the non-return mechanism 4, the limiting tooth 43 contacts the teeth of the limiting rack 44 under the action of the second spring 46 to avoid rebound of the first spring 7, so that the worm blank always maintains effective contact with the surface of the supporting platform 2, ensuring the forging quality, eliminating the need to frequently adjust the positions of the clamping parts and the forging parts, thereby improving the forging efficiency of the workpiece.

[0025] Figure 1 and 4A second embodiment is shown, which mainly differs from the first embodiment in that the adjusting mechanism 5 includes a connecting cylinder 51, which is fixedly connected to the top end of the support rod 8, and the inner wall of the connecting cylinder 51 is rotatably connected to a connecting rod 52, one end of the connecting rod 52 passes through the connecting cylinder 51 and extends to the outside of the connecting cylinder 51, and one end of the connecting rod 52 located outside the connecting cylinder 51 is fixedly connected to the three-jaw chuck 9, and the inner wall of the connecting cylinder 51 is rotatably connected to a rotating rod 53, one end of the rotating rod 53 is fixedly connected to a worm 54, and the surface of the connecting rod 52 is fixedly connected to a worm wheel 55 adapted to the worm 54.

The connecting rod 52 rotates through the three-jaw chuck 9 to drive the worm blank to rotate together, so that the forging machine can forge the peripheral surface of the worm blank and effectively improve the quality of the finished forged parts.

[0027] When in use, the two ends of the worm blank to be processed are fixed by the three-jaw chuck 9. During the forging process, when the worm blank is stamped and forged, when the forging machine stamps and forges the worm blank, the worm blank is deformed and the worm blank moves downward through the three-jaw chuck 9 and the adjusting mechanism 5, and the first spring 7 is compressed by the support rod 8 and the movable plate 6. When the first spring 7 is compressed, the limit tooth 43 contacts the teeth of the limit rack 44 under the action of the second spring 46 to avoid the first spring 7 from rebounding, so that the worm blank always maintains effective contact with the surface of the supporting platform 2, thereby ensuring the quality of forging, rotating the rotating rod 53 to drive the worm 54 to rotate together, and through the meshing action, drive the worm wheel 55 and the connecting rod 52 to rotate together, and the connecting rod 52 rotates through the three-jaw chuck 9 to drive the worm blank to rotate together, so that the forging machine can forge the worm blank conveniently.
