[0032] Example 1

[0033] See also Figure 1-Figure 3 This embodiment provides a bar straightening device to solve the problem that it is inconvenient to quickly check the overall straightness of existing long bars.

[0034] In this embodiment, the bar straightening device includes a movable plate 20 slidably clamped on the base 10, and two rollers 30 for supporting the bar are rotatably connected to the movable plate 20. A positioning column 40 that can press against the side wall of the base 10 is provided on the side plate 22 of the movable plate 20, and an operating plate 42 is fixedly connected to the circumferential surface of the positioning column 40. An eccentrically arranged rectangular slider 41 is fixedly connected to the end face of the positioning column 40. The slider 41 is adaptively clamped in the slide groove 23 on the side plate 22, and a rotating groove 24 is provided at the end of the slide groove 23 for rotating the slider 41.

[0035] In this embodiment, the operating plate 42 drives the slider 41 to rotate in the rotating groove 24, so that the circumferential surface of the eccentrically arranged positioning column 40 can be pressed against the side wall of the base 10, thereby fixing the position of the movable plate 20. By observing whether there is any swinging phenomenon when the bar rotates on the roller 30, the overall straightness of the long bar can be quickly and intuitively checked.

[0036] It should be noted that the base 10 is constructed as a whole into a longitudinal rectangular straight plate shape, the base 10 is placed horizontally on the ground as a whole, the movable plate 20 is constructed as a whole into a U-shaped plate shape, the movable plate 20 can be slidably clamped on the base 10, the movable plate 20 is arranged along the width direction of the base 10 as a whole, and the two side plates 22 of the movable plate 20 are attached to the two side walls of the base 10, two movable plates 20 are arranged at intervals on the base 10, and the sliding clamping of the movable plate 20 on the base 10 makes the distance between the two movable plates 20 adjustable, which is convenient for rapid verification of the overall straightness of bars of different lengths.

[0037] In addition, a U-shaped support platform 21 is welded at the middle position of the movable plate 20. The support platform 21 is arranged vertically with the movable plate 20 as a whole. Two rollers 30 are rotatably provided on the support platform 21, and the two rollers 30 are arranged at intervals along the width direction of the base 10. The rotation axis of the roller 30 is parallel to the longitudinal direction of the base 10. The rod is placed between the two rollers 30. The rollers 30 support the rod, which can facilitate the rotation of the rod between the two rollers 30. If the rod is bent, the rod will swing when it rotates, and the overall straightness of the rod can be intuitively identified; on the contrary, if the rotation of the rod is stable, it means that the overall straightness of the rod is good.

[0038] In addition, a rectangular avoidance groove 25 is provided on one side plate 22 of the movable plate 20, and the avoidance groove 25 passes through the lower end of the side plate 22, so that the avoidance groove 25 is U-shaped as a whole, and rectangular slide grooves 23 are provided on the two side walls of the avoidance groove 25, and the slide grooves 23 extend in a direction perpendicular to the movable plate 20, and a circular rotation groove 24 is also provided on the top of the slide groove 23, and the positioning column 40 is constructed as a whole in a cylindrical shape, and the positioning column 40 is placed in the avoidance groove 25 as a whole, and sliders 41 with a rectangular cross-section are integrally formed on the two end surfaces of the positioning column 40, and the sliders 41 are symmetrically arranged on both sides of the positioning column 40, and the shape of the sliders 41 is adaptively clamped It is connected to the inside of the slide groove 23, and the slider 41 can slide up and down along the slide groove 23. The length of the diagonal of the cross section of the slider 41 is equal to the diameter of the rotating groove 24. When the slider 41 moves upward into the rotating groove 24, the slider 41 can rotate around the axis of the rotating groove 24 inside the rotating groove 24. Since the positioning column 40 and the slider 41 are eccentrically arranged as a whole, the positioning column 41 and the rotating groove 24 are also eccentrically arranged. When the slider 41 rotates inside the rotating groove 24, it will drive the positioning column 40 to rotate synchronously. At this time, the position of the movable plate 20 can be fixed by squeezing the circumferential surface of the positioning column 40 and the side wall of the base 10.

[0039] It should be noted that the positioning column 40 is made of rubber material as a whole, so that the positioning column 40 can undergo a certain deformation after being squeezed. The operating plate 42 is integrally formed on the circumference of the positioning column 40, and the operating plate 42 is arranged along the axial direction of the positioning column 40. The operating plate 42 makes the rotation of the positioning column 40 easier.

[0040] It should also be noted that, in the initial state, the slider 41 is located at the lower end of the slide groove 23, the circumferential surface of the positioning column 40 does not contact the side wall of the base 10, and the operating plate 42 is facing downward as a whole. At this time, the movable plate 20 can slide freely on the base 10; after the slider 41 is pushed upward to the inside of the rotating groove 24, the operating plate 42 can be rotated upward to face upward as a whole. At this time, the circumferential surface of the positioning column 40 is pressed tightly against the side wall of the base 10, and the positioning column 40 has a locking effect on the movable plate 20. At this time, the position of the movable plate 20 on the base 10 is fixed.

[0041] When in use, first drive the positioning column 40 to rotate through the operating plate 42, so that the circumference of the positioning column 40 is separated from the side wall of the base 10. At this time, the movable plate 20 loses the lock of the positioning column 40, and the two movable plates 20 can be adjusted to an appropriate distance. Then, the positioning column 40 is driven to rotate through the operating plate 42, so that the circumference of the positioning column 40 abuts against the side wall of the base 10. At this time, the movable plate 20 is locked by the positioning column 40, and the positions of the two movable plates 20 can be fixed; finally, the rod is mounted on the roller 30 and rotated. By observing whether there is a swinging phenomenon when the rod rotates, the overall straightness of the rod can be verified.

[0042] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application.
