[0013] like Figure 1-3 As shown, this embodiment is an automatic detection device for a bar straightening machine, including a base plate 1, a slide rail 2 on the base plate 1, and several detection mechanisms mounted on the slide rail 2. Each detection mechanism includes a support 3, the bottom of which is slidably connected to the slide rail 2. A locking bolt is provided on one side of the support 3 to fix the position of the detection mechanism. A support plate is provided in the middle of the support 3, and a displacement sensor 5 is mounted on one end of the support plate. A swing rod 6 is mounted on the top of the support 3 and is rotatably connected to the support 3. A pressure block is mounted on the bottom of the end of the swing rod 6 facing the displacement sensor 5, and the pressure block cooperates with the displacement sensor 5. A detection rod 7 is mounted on the end of the swing rod 6 facing the bar and is connected and fixed to the swing rod 6. A return spring 4 is mounted on the support 3 and is fixedly connected to the middle of the swing rod 6.

[0014] Furthermore, the detection rod 7 is L-shaped, and one end of the swing rod 6 has a through hole. The short side of the detection rod 7 is inserted into the through hole, and an adjusting screw is installed on one side of the through hole to fix the position of the detection rod 7. The height of the detection rod 7 can be finely adjusted by sliding it within the through hole according to the actual situation. After adjustment, the adjusting screw can be locked.

[0015] Furthermore, the pressure block is connected to the swing arm 6 by bolts, and the pressure block is made of PVC.

[0016] Furthermore, the lower end of the support 3 is provided with a connecting plate, and the middle of the support plate is provided with a through hole. The return spring 4 passes through the through hole and is fixedly connected to the connecting plate. The working principle of this utility model is as follows: the two ends of the bar are clamped by the clamping mechanism and drive the bar to rotate. The bar is located above the detection rod 7, and the bottom of the bar contacts the detection rod 7 and applies slight pressure. When the bar rotates, the points with excessive bending will cause the corresponding detection rod 7 to produce obvious displacement. The detection rod 7 drives the swing arm 6 to rotate, so that the corresponding displacement sensor 5 can detect the displacement of the point, and thus detect the offset of the point. Each displacement sensor 5 transmits the detection data to the main control system for processing. The program automatically calculates the points that need to be straightened and the straightening amount.
