[0026] The bottom plate 1 supports the first motor 201 and the processing table 202 . When the first motor 201 is started, the screw 203 can be driven to rotate forward and reversely. After the screw 203 rotates, the first support plate 204 can be driven to slide forward and backward along the upper surface of the bottom plate 1 .

[0027] The inner wall of the processing table 202 is inlaid with a bearing 3, and the inner ring of the bearing 3 is fixedly connected to the outer surface of the screw 203. The bearing 3 can make the screw 203 more stable when rotating, avoiding the screw 203 from getting stuck and swinging during use.

[0028] The outer surface of the screw rod 203 is threadedly connected to a slider 4, and the inner wall of the slider 4 is hinged with a support rod 5 through a pin shaft.

The output shaft of the second motor 205 passes through the first support plate 204 and is rotatably connected to the first support plate 204 . A chuck 206 is fixedly connected to the output shaft end of the second motor 205 .

The staff clamps and fixes the tail of the anchor bolt to be thread rolled through the three claws on the chuck 206.

[0032] Two symmetrical second support plates 207 are fixedly connected to the upper surface of the processing table 202, and the side surfaces of the two second support plates 207 that are away from each other are fixedly connected to the first cylinder 208.

[0035] Example 2

[0036] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that two symmetrical third support plates 9 are fixedly connected to the upper surface of the processing table 202, and the side surfaces of the two third support plates 9 that are away from each other are fixedly connected to the second cylinder 10, and the output shafts of the two second cylinders 10 pass through the third support plates 9 and are slidably connected to the third support plates 9, and the output ends of the two second cylinders 10 are fixedly connected to support frames 11, and the inner walls of the two support frames 11 are slidably connected to thread rolling plates 12.

The mounting blocks 14 can be used to conveniently install the base plate 1, thereby realizing the installation of the thread rolling machine for processing anchor bolts, ensuring the stability of the thread rolling machine for processing anchor bolts during use, and at the same time, the installation position can be fine-tuned.

[0040] Working principle: When using the thread rolling machine for processing anchor bolts, the staff can clamp and fix the tail of anchor bolts of different diameters through the three claws on the chuck 206, and then control the two first cylinders 208 to start synchronously, so as to control the two arc plates 209 to approach synchronously, until the two arc plates 209 fit the anchor bolts, so as to achieve auxiliary support for the middle part of the anchor bolts. At the same time, under the action of lubricating oil, the two arc plates 209 will not hinder the movement of the anchor bolts, and then control the first motor 201 to start. After the first motor 201 is started, it can The screw rod 203 is driven to rotate. After the screw rod 203 rotates, it can drive the first support plate 204 to move along the upper surface of the base plate 1, and then drive the anchor bolt clamped on the chuck 206 to move to the externally arranged thread rolling device through the second motor 205. Then, the second motor 205 is started, which can drive the chuck 206 to rotate, and then drive the anchor bolt clamped on the chuck 206 to rotate, so that the anchor bolt gradually completes the thread rolling process while rotating. The debris generated by the thread rolling process falls from the slot opened on the processing table 202 to the processing table 202 for collection, so as to be subsequently cleaned up.
