Detailed Embodiment

[0038] The following further describes the present application in detail in conjunction with the attached Figures 1-6 drawings.

[0039] The embodiment of the present application discloses a material clamping mechanism.

[0040] Refer to Figure 1, the material clamping mechanism includes a driving member 1 and a clamping assembly 2. The driving member 1 and the clamping assembly 2 are arranged at intervals. In this embodiment, the driving member 1 is a cylinder. In other embodiments, the driving member 1 can also be an oil cylinder, an electric push cylinder, etc.

[0041] Refer to Figure 1 and Figure 2 , specifically, the clamping assembly 2 includes a mounting seat 21, a connecting plate 22 and two clamping members 23. The mounting seat 21 is provided with a first sliding groove 211 along its own width direction. The connecting plate 22 is slidably connected in the first sliding groove 211, so that the connecting plate 22 is slidably connected to the mounting seat 21 along the width direction of the mounting seat 21. Among them, the driving member 1 is located on one side of the mounting seat 21 and the power output shaft is fixedly connected to the connecting plate 22 to drive the connecting plate 22 to slide.

[0042] Refer to Figure 2 and Figure 3 , the connecting plate 22 is provided with an inclined first guiding groove 221 and a second guiding groove 222. The first guiding groove 221 and the second guiding groove 222 are arranged at intervals along the length direction of the mounting seat 21, and the first guiding groove 221 and the second guiding groove 222 are symmetrically arranged, so that the first guiding groove 221 and the second guiding groove 222 are arranged in an "eight" shape.

[0043] The two clamping members 23 are arranged oppositely. The mounting seat 21 is provided with a second sliding groove 212 along its own length direction. The two clamping members 23 are slidably connected in the second sliding groove 212, so that the two clamping members 23 are slidably connected to the mounting seat 21 along the length direction of the mounting seat 21. At the same time, the lower ends of the two clamping members 23 are respectively limited in the first guiding groove 221 and the second guiding groove 222.

[0044] In practical applications, the driving member 1 drives the connecting plate 22 to slide along the width direction of the mounting seat 21. Under the action of the first guiding groove 221 and the second guiding groove 222, the connecting plate 22 drives the two clamping members 23 to approach each other to realize the clamping and fixing of the bar. During this process, the two clamping members 23 can realize synchronous movement by driving the connecting plate 22 to move by a single driving member 1, so as to ensure the consistency of the movement of the two clamping members 23, thereby improving the clamping and fixing effect on the bar. Moreover, only using a single driving member 1 can also reduce the production and manufacturing cost of the material clamping mechanism.

[0045] In some embodiments, the clamping member 23 includes a sliding block 231 and clamping pieces 232. The sliding block 231 is arranged in a rectangular block shape. The lower end of the sliding block 231 is slidably connected to the second sliding groove 212. One end of the sliding block 231 protrudes to form a limiting post 231a. The limiting post 231a movably penetrates through the mounting seat 21 to ensure the normal sliding operation of the sliding block 231. The two limiting posts 231a respectively movably penetrate through the first guiding groove 221 and the second guiding groove 222 to limit the sliding block 231 to be movably positioned in the first guiding groove 221 or the second guiding groove 222. The clamping pieces 232 are detachably connected to one side of the sliding block 231, so that the bar is clamped and fixed between two opposite clamping pieces 232. In this way, by replacing the clamping pieces 232 with different shapes, it can be applied to other special-shaped pipes, thereby improving the applicability of the material clamping mechanism, or the severely worn clamping pieces 232 can be replaced to ensure the effect of clamping and fixing the bar.

[0046] In some embodiments, the clamping member 23 further includes a first bolt 233. One end of the first bolt 233 movably penetrates through the clamping piece 232 and is threadedly connected to the sliding block 231, and the other end abuts against the clamping piece 232 to achieve the detachable connection between the clamping piece 232 and the sliding block 231, with a simple structure and convenient operation. In other embodiments, the detachable connection of the clamping piece 232 can also be achieved by means of clamping, plugging, etc.

[0047] In some embodiments, a mounting groove 231b is formed on one side of the sliding block 231. The shape of the mounting groove 231b is adapted to the shape of the clamping piece 232. The clamping piece 232 is partially embedded in the mounting groove 231b to facilitate the positioning and installation of the clamping piece 232, thereby facilitating the alignment and installation of the first bolt 233.

[0048] In some embodiments, the number of the clamping pieces 232 is two. The two clamping pieces 232 are respectively arranged on both sides of the sliding block 231, so that the bar is clamped and fixed between the four clamping pieces 232 to improve the stability of clamping and fixing the bar.

[0049] Refer to Figure 2 and Figure 4, in some embodiments, the material clamping mechanism further includes a detection component 3. The detection component 3 includes a movable plate 31, a detection plate 32, a sensor 33, and an elastic member 34. The movable plate 31 is slidably connected to one side of one of the sliding blocks 231, and the sliding direction is the length direction of the mounting seat 21. One end of the movable plate 31 is provided with an abutting groove 311 for abutting against the bar. At the same time, the detection plate 32 is fixedly connected to the sliding block 231 on the side of the movable plate 31, the sensor 33 is threadedly connected to the movable plate 31, and one end of the sensor 33 is aligned with the detection plate 32. The elastic member 34 is a spring. One end of the elastic member 34 is fixedly connected to the movable plate 31, and the other end is fixedly connected to the detection plate 32 to drive the movable plate 31 to slide so that one end of the sensor 33 abuts against the detection plate 32.

[0050] Among them, when the sensor 33 is away from the detection plate 32, that is, when the sensor 33 does not abut against the detection plate 32, it means that a bar is detected to be clamped. When the sensor 33 abuts against the detection plate 32, it means that no bar is detected to be clamped. By the cooperation of the sensor 33 and the detection plate 32, it can be detected whether the two clamping members 23 clamp the bar.

[0051] In some embodiments, the detection component 3 further includes a second bolt 35. The movable plate 31 is provided with a movable groove 312 along its own length direction. One end of the second bolt 35 passes through the detection plate 32 and the movable groove 312 and is threadedly connected to the sliding block 231, so that the movable plate 31 is located between the sliding block 231 and the detection plate 32, thus realizing the sliding connection of the movable plate 31 to the clamping member 23 and the installation of the detection plate 32.

[0052] In some embodiments, the number of the second bolts 35 is two. The two second bolts 35 are arranged at intervals along the length direction of the movable groove 312. Under the action of the two second bolts 35, the rotation of the movable plate 31 can be restricted, thereby improving the sliding stability of the movable plate 31. And the installation stability of the detection plate 32 can be improved.

[0053] The implementation principle of this embodiment is: in practical applications, the driving member 1 drives the connecting plate 22 to slide along the width direction of the mounting seat 21. Under the action of the first guiding groove 221 and the second guiding groove 222, the connecting plate 22 drives the two clamping members 23 to approach each other to realize the clamping and fixing of the bar. In this process, the two clamping members 23 can realize synchronous movement by driving the connecting plate 22 to move by a single driving member 1, so as to ensure the consistency of the movement of the two clamping members 23, thereby improving the clamping and fixing effect on the bar. And only using a single driving member 1 can also reduce the production and manufacturing cost of the material clamping mechanism.

[0054] The embodiment of the present application also discloses a bar feeder.

[0055] Refer to Figure 5 andFigure 6 , the bar feeder includes a frame 4 and the clamping mechanism described in the above embodiment. The driving member 1 and the clamping assembly 2 are arranged at intervals along the length direction of the frame 4, and the driving member 1 and the mounting seat 21 are fixedly connected to the frame 4.

[0056] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
