[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 An embodiment of this utility model provides a lead screw straightening device, including: a workbench 1, a straightening mechanism 2 for straightening lead screws installed on the top of the workbench 1, a control box 3 installed on one side of the workbench 1, a controller installed in the control box 3, and the controller being electrically connected to the straightening mechanism 2 through a wire.

[0024] The straightening mechanism 2 includes a convex roller 201 and a concave roller 202. The two ends of the convex roller 201 and the concave roller 202 are rotatably connected to the bearing seat 203, and a lead screw 4 is abutted between the convex roller 201 and the concave roller 202.

[0025] One end of the cam roller 201 is equipped with a motor 204, which is fixed on the bearing housing 203. The motor 204 is electrically connected to the controller via a wire. By connecting the motor 204 to the controller via the wire, the controller controls the rotation of the motor 204, thereby driving the cam roller 201 to rotate, in order to straighten the lead screw 4.

[0026] The convex roller 201 and concave roller 202 are made of high-strength steel. This high-strength steel is alloy tool steel, which boasts high strength and toughness. While withstanding straightening forces, it effectively resists the impact caused by irregular bending of the lead screw, reducing the risk of roller breakage. Furthermore, it has good machinability, allowing for the manufacture of roller types to meet different lead screw straightening requirements through various machining methods. For example, rollers with specific grooves to match the lead screw pitch can be used, thus achieving lead screw straightening and enabling semi-automation of the equipment, significantly reducing operator workload. Specifically, the alloy tool steel is Cr12MoV, H13, or 9SiCr, and through quenching and tempering treatment, its hardness reaches HRC 48-62, combining high strength, wear resistance, and impact resistance to meet the straightening requirements of different lead screw specifications.

[0027] The bearing housing 203 has a guide rail groove 205 at its bottom, which is slidably connected to a guide rail 206. The guide rail 206 is fixed to the top of the workbench 1. One end of the bearing housing 203 has a threaded hole 207, and a screw 208 is screwed into the threaded hole 207. One end of the screw 208 is rotatably connected to a bearing housing 212, which is fixedly mounted on the workbench 1. By screwing the screw 208 onto the bearing housing 212, with one end screwed into the threaded hole 207 at one end of the bearing housing 203, the guide rail groove 205 at the bottom of the bearing housing 203 slides on the guide rail 206. By adjusting the screw 208, it is possible to straighten lead screws 4 of different thicknesses, greatly improving the utilization rate of the equipment and effectively reducing the factory's operating costs.

[0028] One end of the screw 208 is equipped with a handle 209. By installing the handle 209, it is easy for the operator to rotate the screw 208 to adjust the lead screws 4 of different thicknesses.

[0029] The bearing housing 203 has a sliding rod 210 slidably connected to its top, and limit blocks 211 are fixedly connected to both ends of the sliding rod 210. By sliding the sliding rod 210 to the top of the bearing housing 203, the stability of the bearing housing 203 can be further improved, thereby enabling the convex roller 201 and concave roller 202 on the bearing housing 203 to straighten the lead screw 4.

[0030] The controller can be a Siemens S7-300 series PLC controller.

[0031] The working principle of this utility model is as follows: In use, the straightening mechanism 2 is adjusted according to the thickness of the lead screw 4. The screw 208 is rotated so that one end is screwed into the threaded hole 207 at one end of the bearing seat 203. This causes the guide groove 205 at the bottom of the bearing seat 203 to slide on the guide rail 206. The motor 204 is started by the controller to drive the cam roller 201 to rotate, thereby straightening the lead screw 4. This makes the equipment semi-automatic, which greatly reduces the operation of the workers. By adjusting the screw 208, lead screws 4 of different thicknesses can be straightened, which greatly improves the utilization rate of the equipment and effectively reduces the operating cost of the factory.

[0032] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
