[0002] When using automobile steel plates, they need to be stamped into various shapes, such as automobile door bodies, by stamping. Stamping is a production technology that relies on the power of conventional or special stamping equipment to directly deform the sheet metal in the mold, thereby obtaining product parts with certain shapes, sizes, and properties. The sheet metal, mold, and equipment are the three elements of stamping processing. According to the stamping processing temperature, it is divided into hot stamping and cold stamping.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of 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.

[0027] Please refer to Figures 1-4 , the present utility model provides a new technical solution: a quick positioning mechanism for steel plate processing, including four legs 1 of the steel plate processing workbench. The upper surface of the legs 1 of the steel plate processing workbench is fixedly installed with a steel plate processing workbench 2, and four electric guide rails 3 are fixedly installed on the upper surface of the steel plate processing workbench 2;

[0028] Among them, a positioning mechanism is provided on the steel plate processing workbench 2. The positioning mechanism includes two moving plates 4, two first chutes 5, two T-shaped plates 6, eight dampers 7, eight springs 8, eight piston rods 9, two second chutes 10, two bidirectional threaded rods 11, two knobs 12, four sliding blocks 13 and four cylinder jaws 14.

[0029] Furthermore, the two moving plates 4 are respectively slidably sleeved on the outer surfaces of the four electric guide rails 3, and the two first chutes 5 are respectively opened on the upper surfaces of the two moving plates 4;

[0030] Among them, the vertical plates of the two T-shaped plates 6 are respectively slidably sleeved on the inner surfaces of the two first chutes 5.

[0031] Furthermore, the eight dampers 7 are respectively fixedly installed on the upper surfaces of the two moving plates 4, and the eight springs 8 are respectively fixedly installed on the upper surfaces of the eight dampers 7.

[0032] Furthermore, the eight piston rods 9 are fixedly installed at the upper ends of the eight springs 8, and the eight piston rods 9 are respectively slidably sleeved on the inner surfaces of the eight dampers 7.

[0033] Further, two second sliding grooves 10 are respectively formed in the upper surfaces of the cross plates of the two T-shaped plates 6. The left ends of the two bidirectional threaded rods 11 are respectively rotatably connected to the inner walls of the two second sliding grooves 10, and the right ends of the two bidirectional threaded rods 11 respectively penetrate through the right surfaces of the cross plates of the two T-shaped plates 6;

[0034] Among them, two knobs 12 are respectively fixedly installed at the right ends of the two bidirectional threaded rods 11.

[0035] Further, four sliding blocks 13 are respectively sleeved on the outer surfaces of the two bidirectional threaded rods 11 in a threaded manner, and the four sliding blocks 13 are respectively slidably connected to the two second sliding grooves 10;

[0036] Among them, four cylinder grippers 14 are respectively fixedly installed on the upper surfaces of the four sliding blocks 13;

[0037] When the rapid positioning mechanism for steel plate processing is in use, by placing the steel plate between the four cylinder grippers 14, at this time, by rotating the knob 12, the knob 12 drives the bidirectional threaded rod 11 fixedly installed on the left surface to rotate. At this time, the two sliding blocks 13 sleeved on the outer surface of the bidirectional threaded rod 11 continuously move towards the opposite surface through the thread provided on the outer surface of the bidirectional threaded rod 11, and can be adjusted according to the different widths of the steel plate. At this time, the cylinder grippers 14 fixedly installed on the upper surfaces of the two sliding blocks 13 are close to the outer surface of the steel plate. At this time, by starting the cylinder grippers 14 to clamp the steel plate, and by starting the four electric guide rails 3, the four electric guide rails 3 drive the two moving plates 4 sleeved on the outer surface to move towards the opposite surface on the outer surface of the electric guide rails 3 through operation. At this time, it can be adjusted according to the different lengths of the steel plate. After the adjustment is completed, it can be clamped and fixed by the cylinder grippers. When the steel plate is stamped on the surface, the T-shaped plate 6 moves downward under force. The T-shaped plate 6 exerts a downward pressure on the four piston rods 9 fixedly installed on the lower surface, causing them to move downward. The four piston rods 9 slowly move downward on the inner surface of the damper 7. The damper 7 in the present invention is a hydraulic damper. The hydraulic damper will consume energy through the damping oil and damping holes, thereby slowing down or preventing the mechanical movement process, thereby the transmission of force when the T-shaped plate 6 is pressed, achieving a certain buffering effect. At the same time, the piston rod 9 exerts a pressure on the spring 8 fixedly installed on the lower surface, causing it to contract, and a certain buffer is formed by the elastic potential energy of the spring 8 itself;

[0038] The quick positioning mechanism for steel plate processing can adjust the distance between two moving plates 4 through four electric guide rails 3, so as to adjust and fix steel plates of different lengths. It can also drive two cylinder jaws 14 to move towards the opposite side by a bidirectional threaded rod 11 to adjust and fix them according to the width of the steel plate, which is convenient for subsequent processing. Moreover, the quick positioning mechanism for steel plate processing can buffer the steel plate during stamping through dampers 7, springs 8 and piston rods 9, preventing the situation of fracture caused by excessive local stress, making steel plate processing more convenient.

[0039] Working principle: When the quick positioning mechanism for steel plate processing is in use, place the steel plate between four cylinder jaws 14. At this time, rotate the knob 12, and the knob 12 drives the bidirectional threaded rod 11 fixedly installed on the left surface to rotate. At this time, two sliding blocks 13 sleeved on the outer surface of the bidirectional threaded rod 11 continuously move towards the opposite side through the threads provided on the outer surface of the bidirectional threaded rod 11, and can be adjusted according to the different widths of the steel plate. At this time, the cylinder jaws 14 fixedly installed on the upper surfaces of the two sliding blocks 13 are close to the outer surface of the steel plate. At this time, start the cylinder jaws 14 to clamp the steel plate, and can start four electric guide rails 3. The four electric guide rails 3 drive two moving plates 4 sleeved on the outer surface to move towards the opposite side on the outer surface of the electric guide rails 3 through operation. At this time, it can be adjusted according to the different lengths of the steel plate. After the adjustment is completed, it can be clamped and fixed by the cylinder jaws. When the steel plate is stamped on the surface, the T-shaped plate 6 is stressed and moves downward. The T-shaped plate 6 exerts a downward pressure on the four piston rods 9 fixedly installed on the lower surface, causing them to move downward. The four piston rods 9 slowly move downward inside the damper 7. The damper 7 in the present invention is a hydraulic damper. The hydraulic damper will consume energy through damping oil and damping holes, thereby slowing down or preventing the process of mechanical movement, thus achieving the transfer of force when the T-shaped plate 6 is stressed and achieving a certain buffering effect. At the same time, the piston rod 9 exerts a pressure on the spring 8 fixedly installed on the lower surface, causing it to contract, and a certain buffering is formed by the elastic potential energy of the spring 8 itself.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
