When processing sheet metal brackets, a positioning device is usually required to position them. Existing sheet metal positioning devices are not flexible enough to adjust the position according to the size of the sheet metal bracket, so they cannot firmly clamp sheet metal brackets of different specifications. In view of the above problems, a solution is proposed below. Utility Model Content

[0018] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figures 1 to 3 As shown, a positioning device for a sheet metal bracket includes a base 1, and a plurality of universal wheels 27 are symmetrically fixed at the lower end of the base 1. The plurality of universal wheels 27 can facilitate the movement and fixation of the entire device, thereby improving the use range of the device. A support plate 2 is arranged above the base 1, and a lifting mechanism 3 is arranged at the upper end of the base 1. The lifting mechanism 3 is connected to the support plate 2 to drive the support plate 2 to move up and down. The lifting mechanism 3 can drive the support plate 2 to move up and down to adjust the height of the support plate 2, so that the processing height of the sheet metal bracket can be adjusted, which is conducive to better processing of the sheet metal bracket to improve the processing efficiency of the sheet metal bracket.

[0020] The lifting mechanism 3 includes a motor 17 mounted on the upper end of the base 1, a worm 18 is fixedly arranged on the output shaft of the motor 17, a protrusion 19 is fixedly arranged on the upper end of the base 1, and the other end of the worm 18 is rotatably connected to the protrusion 19, and the rotation of the motor 17 can drive the worm 18 to rotate. A rotatable shaft 20 is arranged on the base 1, a worm wheel 21 is fixedly arranged on the shaft 20, and the worm wheel 21 is meshed with the worm 18, a screw 22 is fixedly arranged on the upper end of the shaft 20, a threaded barrel 23 is fixedly arranged on the lower end of the support plate 2, and the upper end of the screw 22 is inserted into the threaded barrel 23, the rotation of the worm 18 can drive the worm wheel 21 to rotate, thereby driving the shaft 20 to rotate, and finally driving the screw 22 to rotate, so that the threaded barrel 23 can be moved up and down by the rotation of the screw 22, and finally the support plate 2 can be driven to move up and down, so that the height of the support plate 2 can be adjusted.

[0021] A plurality of guide cylinders 24 are fixedly provided at the upper end of the base 1, and a plurality of guide posts 25 are fixedly provided at the lower end of the support plate 2. The lower ends of the plurality of guide posts 25 are slidably located in the plurality of guide cylinders 24 respectively. When the support plate 2 moves up and down, the plurality of guide posts 25 can slide up and down along the plurality of guide cylinders 24 respectively, so that the support plate 2 can move more straight and stably when moving up and down, so as to ensure the stability during sheet metal processing.

[0022] Two first grooves 4 are symmetrically provided at the upper end of the support plate 2, and a rotatable threaded rod 5 is respectively penetrated in each first groove 4. The thread directions of the two threaded rods 5 are opposite, and one end is fixedly connected. A turning handle 6 is provided on one side of the support plate 2, and the other end of the threaded rod 5 is fixedly connected to the turning handle 6. By rotating the turning handle 6, the two threaded rods 5 can be driven to rotate at the same time. Slidable threaded seats 7 are respectively provided in the two first grooves 4, and the threaded seats 7 are penetrated on the threaded rod 5. Since the thread directions of the two threaded rods 5 are opposite, the two threaded seats 7 can slide along the two first grooves 4 and approach or move away from each other by rotating the two threaded rods 5.

[0023] Four second grooves 8 are symmetrically arranged on the support plate 2, and a slidable adjustment block 9 is respectively embedded in each second groove 8. A first adjustment rod 10 is respectively hinged between the upper end of each threaded seat 7 and the upper ends of every two adjustment blocks 9. Four third grooves 11 are symmetrically arranged on the support plate 2, and a slidable slider 12 is respectively embedded in each third groove 11. When the two threaded seats 7 are close to each other, they can be swung and adjusted by two adjacent first adjustment rods 10 and second adjustment rods 14 respectively. At this time, the angle between the first adjustment rod 10 and the second adjustment rod 14 becomes smaller, and at the same time, the adjustment block 9 slides forward along the second groove 8, and the slider 12 slides forward along the third groove 11, which can eventually make the two adjacent sliders 12 approach each other. Conversely, when the two threaded seats 7 move away from each other, the two adjacent sliders 12 slide backward along the third groove 11 respectively and move away from each other.

[0024] A T-shaped column 13 is fixed to the upper end of each slider 12, and a second adjusting rod 14 is hinged between the upper ends of the four adjusting blocks 9 and the four T-shaped columns 13, and a clamping plate 15 is provided above every two sliders 12, and a T-shaped slot 16 is provided at the lower end of the clamping plate 15. Every two T-shaped columns 13 can be slidably embedded in the T-shaped slot 16, respectively. When two adjacent sliders 12 slide forward along the third groove 11 and approach each other, the T-shaped column 13 can be driven to slide along the T-shaped slot 16 and approach each other, and finally the two clamping plates 15 can be brought close to each other, so as to facilitate positioning and clamping of the sheet metal bracket. Conversely, when two adjacent sliders 12 slide backward along the third groove 11 and move away from each other, the two clamping plates 15 are separated from each other, and finally the distance between the two clamping plates 15 can be adjusted to adapt to the sheet metal brackets of different specifications for firm clamping, which can further improve the efficiency of sheet metal bracket processing.

[0025] A protective pad 26 is fixed to one side of the two clamping plates 15 respectively. The protective pad 26 is elastic and can prevent the sheet metal bracket clamped between the two clamping plates 15 from sliding, and can also effectively prevent the surface of the sheet metal bracket from being deformed due to excessive clamping force.

[0026] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
