[0002] Metal bars are a common type of metal products and are widely used in multiple fields. As blank parts in many fields, metal bars need to be further finely processed, such as surface grinding and cutting into shape. The above steps all require positioning of the metal bars.
[0003] Generally, two metal plates are used to clamp the metal bar for positioning. However, such a clamping method still has problems. This clamping method results in too small a contact area between the clamping plate and the end face of the metal bar, and it is difficult to master the clamping force. At this time, when the clamping force is too small, the bar may be unstably clamped and break away from the two metal plates. If the clamping force of the metal plates is increased, it will cause damage to the metal bar due to clamping. Therefore, when rough processing the bar, the metal bar can be positioned by a clamping method. Content of the Utility Model

A docking frame is provided at the bottom of the rotating shaft, and the bottom end of the docking frame is fixedly connected with a clamping frame.
[0006] Preferably, insertion slots are opened on both sides of the positioning frame. After both ends of the clamping frame penetrate the insertion slots, the clamping frame is movably inserted into the insertion slots.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1-3, A clamping and positioning mechanism for bar processing, including a processing table 1, a clamping frame 2 and a support base 3. Two support bases 3 are fixedly installed on the top of the processing table 1, and a clamping frame 2 is fixedly installed on the support bases 3. The clamping frame 2 includes a positioning frame 21, a driving motor 22, a stable frame 23, a rotating shaft 24, a docking frame 25 and a clamping frame 26. A driving motor 22 is provided at the top of the positioning frame 21, and a stable frame 23 is provided between the driving motor 22 and the positioning frame 21. The bottom of the driving motor 22 is connected with a rotating shaft 24, and the stable frame 23 is penetrated by the rotating shaft 24. The stable frame 23 maintains the stability of the rotating shaft 24 during rotation. A docking frame 25 is provided at the bottom of the rotating shaft 24, and the bottom end of the docking frame 25 is fixedly connected with a clamping frame 26. The driving motor 22 drives the rotating shaft 24 to rotate, and the rotating shaft 24 pushes the docking frame 25 to descend, so that the clamping frame 26 and the positioning frame 21 can jointly clamp and fix the metal bar tightly.
[0019] Further, insertion slots are opened on both sides of the positioning frame 21. After both ends of the clamping frame 26 penetrate the insertion slots, the clamping frame 26 is movably inserted into the insertion slots. A closed relationship is formed between the clamping frame 26 and the positioning frame 21 to prevent the metal bar from falling off therefrom.
[0020] Further, an external thread groove is opened on the outer side of the lower half shaft body of the rotating shaft 24, and an internal thread groove is opened inside the docking frame 25. The rotating shaft 24 is threadedly connected with the docking frame 25. After the driving motor 22 drives the rotating shaft 24 to rotate, the rotating shaft 24 pushes the clamping frame 26 to descend in the insertion slots on both sides of the positioning frame 21 through the external thread groove.
[0021] Further, a lower clamping pad 211 is provided inside the positioning frame 21, and an upper clamping pad 261 is provided inside the clamping frame 26. During the clamping process, the lower clamping pad 211 and the upper clamping pad 261 protect the metal bar to prevent the metal bar from being damaged.
[0022] Further, side slots are also opened on both sides of the support base 3, and the width of the side slots is greater than the width of the clamping frame 26. During the descent of the clamping frame 26, it can enter the side slots.
[0023] Working principle: For a clamping and positioning mechanism for bar processing of the present utility model, during use, one end of the metal bar is placed between the positioning frame 21 and the clamping frame 26. The driving motor 22 is started, and the driving motor 22 drives the rotating shaft 24 to rotate. Through the threaded connection between the external thread groove at the bottom end of the rotating shaft 24 and the docking frame 25, the docking frame 25 pushes the clamping frame 26 to descend in the insertion slots on both sides of the positioning frame 21, so that the clamping frame 26 and the positioning frame 21 jointly clamp and fix the metal bar tightly.
