[0029] As Figures 1 - 3 shown, a sheet metal cutting positioning device includes a base 1. At one end of the upper side of the base 1, two support plates 2 are symmetrically fixed. The specific fixing method is welding fixation, which ensures the fixing effect and further ensures the stability during cutting. A support shaft 3 is fixedly connected between the two support plates 2. A workbench 4 is rotatably connected to the outer side of the support shaft 3. The support shaft 3 can support one end of the workbench 4 to ensure the overall stability. It further includes: an adjustment mechanism and a positioning mechanism. The adjustment mechanism is arranged on the lower side of the support shaft 3; the positioning mechanism is arranged on the inner side of the support shaft 3. The adjustment mechanism includes an installation box 5 fixed on the upper side of the base 1, and two fixing blocks 6 symmetrically fixed on the lower side of the support shaft 3. A motor 7 is installed on the outer side of the installation box 5. The output end of the motor 7 is fixed with a screw rod 8 that rotates and extends into the inner side of the installation box 5. A moving block 9 is rotatably connected to the outer side of the screw rod 8 through threads. Two connecting shafts 10 are symmetrically fixed on the outer side of the moving block 9. One end of the outer sides of the two connecting shafts 10 is rotatably connected to a rotating rod 11. One side of each of the two fixing blocks 6 is fixed with a connecting shaft 12. The other ends of the two rotating rods 11 are respectively rotatably connected to the outer sides of the two connecting shafts 12;

[0030] When it is necessary to cut the sheet metal part at a special angle, turn on the switch of the motor 7 to make it rotate forward. The motor 7 drives the screw rod 8 fixed to its output end to rotate. The screw rod 8 rotates and drives the moving block 9 to move through thread engagement. The moving block 9 moves and drives the two connecting shafts 10 to move synchronously. Then the two rotating rods 11 rotate. Through the rotation of the two rotating rods 11, the angle of the workbench 4 is finally adjusted, and then the inclination of the sheet metal part is controlled. Through the above principle, turn on the motor 7 to make it rotate in reverse. The screw rod 8 rotates, and drives the moving block 9 to move in the reverse direction through thread engagement, and the angle of the workbench 4 can be flattened. The overall operation is simple.

[0031] As Figures 4 - 5As shown, in one embodiment, the positioning mechanism includes a plurality of card slots 13 symmetrically arranged at equal intervals inside the workbench 4, and two positioning rods 14 symmetrically and slidably arranged inside the workbench 4. Two sliding rods 15 are symmetrically fixed to the inner sides of the two positioning rods 14. A moving rod 16 is slidably arranged on the outer side of each of the plurality of sliding rods 15. The plurality of moving rods 16 respectively penetrate and are slidably connected to both ends of the two positioning rods 14, and a block 17 adapted to the plurality of card slots 13 is fixed to the outer end of each of the plurality of moving rods 16. A dial block 18 is fixed to the outer side of each of the plurality of moving rods 16, and adjacent two dial blocks 18 are respectively slidably connected to the inner sides of the two positioning rods 14. Place the sheet metal part to be cut inside the workbench 4, and adjust the distance between the two positioning rods 14 according to the size of the sheet metal part to fix the sheet metal part. During specific operation, respectively and simultaneously move adjacent two dial blocks 18 inward relative to each other. When the plurality of dial blocks 18 move, they drive the plurality of moving rods 16 fixed to them to slide along the outer sides of the plurality of sliding rods 15 respectively, so that the plurality of blocks 17 move, and the plurality of card slots 13 engaged with them are separated. At this time, the two positioning rods 14 can be controlled to move to clamp and fix the sheet metal part.

[0032] As Figure 5 shown, in one embodiment, a spring 19 is sleeved on the outer side of each of the plurality of sliding rods 15. One end of each of the plurality of springs 19 is fixed to the inner side of the positioning rod 14, and the other end of each of the plurality of springs 19 is respectively fixed to one side of the plurality of moving rods 16. When the plurality of moving rods 16 move, they simultaneously squeeze the plurality of springs 19. After moving the two positioning rods 14 to appropriate positions respectively, release the plurality of dial blocks 18. Due to the elastic potential energy of the plurality of springs 19, the plurality of moving rods 16 reset, and further the plurality of blocks 17 reset and are engaged again inside the corresponding card slots 13 to complete the limit.

[0033] As Figure 4 and Figure 5 shown, in one embodiment, in order to ensure the horizontal movement of the two positioning rods 14, a through groove 20 is formed inside the workbench 4, and two sliders 21 are symmetrically and slidably arranged inside the through groove 20. The two sliders 21 are respectively fixed to the lower sides of the two positioning rods 14.

[0034] As Figure 1 shown, in one embodiment, a cutting assembly 22 is fixed to the upper side of the base 1, and the sheet metal part can be cut by the cutting assembly 22.

[0035] As Figure 2 and Figure 3 shown, in one embodiment, in order to ensure the horizontal movement of the moving block 9 and the two first connecting shafts 10, guide grooves 23 adapted to the two first connecting shafts 10 are symmetrically formed inside the mounting box 5, and the two first connecting shafts 10 are respectively slidably connected to the inside of the two guide grooves 23 to play a limiting role.

[0036] AsFigure 5 As shown, in one embodiment, a plurality of rubber bumps 24 are fixedly arranged at equal intervals on one side of the two positioning rods 14, further improving the fixing effect on the sheet metal part.

[0037] The specific working method is as follows: During operation, place the sheet metal part to be cut inside the workbench 4, adjust the distance between the two positioning rods 14 according to the size of the sheet metal part to fix the sheet metal part. Specifically, when operating, relatively move two adjacent sliders 18 inward simultaneously. When the plurality of sliders 18 move, the plurality of moving rods 16 fixed thereto slide along the outer sides of the plurality of sliding rods 15 respectively, so that the plurality of locking blocks 17 move and separate from the plurality of card slots 13 engaged therewith. At this time, the two positioning rods 14 can be controlled to move. When the plurality of moving rods 16 move, they simultaneously squeeze the plurality of springs 19. After moving the two positioning rods 14 to appropriate positions respectively, release the plurality of sliders 18. Due to the elastic potential energy of the plurality of springs 19, the plurality of moving rods 16 reset, and then the plurality of locking blocks 17 reset and are engaged again inside the corresponding card slots 13, completing the limiting. A plurality of rubber bumps 24 are fixedly arranged at equal intervals on one side of the two positioning rods 14, further improving the fixing effect on the sheet metal part. When the sheet metal part needs to be cut at a special angle, turn on the switch of the motor 7 to make it rotate forward. When the motor 7 is turned on, the screw rod 8 fixed to its output end rotates. The rotation of the screw rod 8 drives the moving block 9 to move through thread engagement. The movement of the moving block 9 drives the two connecting shafts I 10 to move synchronously, and then the two rotating rods 11 rotate. Through the rotation of the two rotating rods 11, the angle of the workbench 4 is finally adjusted, and then the inclination of the sheet metal part is controlled. At this time, the sheet metal part can be obliquely cut through the cutting assembly 22. According to the above principle, turn on the motor 7 to make it rotate in reverse, the screw rod 8 rotates, and drives the moving block 9 to move in the reverse direction through thread engagement, and the angle of the workbench 4 can be flattened. The overall operation is simple.
