The sheet metal positioning and cutting device includes: a base 1, a pulling block 2 is fixedly connected to the top of the base 1, a pull rod 3 is slidably connected inside the pulling block 2, the pull rod 3 penetrates through the pulling block 2 and extends to the outside of the pulling block 2, a compression spring 4 is arranged outside the pull rod 3, one end of the pull rod 3 is fixedly connected to a semi-circular block 5, a semi-circular tooth 6 is fixedly connected to one side of the semi-circular block 5, a rotating column 7 is rotatably connected inside the base 1, the rotating column 7 penetrates through the base 1 and extends to the outside of the base 1, a circular supporting block 8 is fixedly connected to the outside of the rotating column 7, a middle groove 9 is opened on the outside of the rotating column 7, a rotating tooth 10 is fixedly connected to the outside of the middle groove 9, the outside of the rotating tooth 10 is meshed with the outside of the semi-circular tooth 6, and a rotating plate 11 is fixedly connected to the top of the rotating column 7.

[0022] Manually pull the pull rod 3 outwards by personnel, so that the pull rod 3 slides inside the pull block 2. A compression spring 4 is arranged outside the pull rod 3. When the pull rod 3 moves, the distance between the semi-circular block 5 and the pull block 2 shortens. When shortening, the compression spring 4 is squeezed and contracted. A semi-circular tooth 6 is installed outside the semi-circular block 5. A rotating column 7 is rotatably connected to the base 1. A middle groove 9 is opened outside the rotating column 7. By fixedly connecting a rotating tooth 10 outside the middle groove 9, when the semi-circular tooth 6 disengages from the rotating tooth 10, the rotating column 7 can rotate. When rotating, the rotating plate 11 at the top of the rotating column 7 rotates synchronously, so that the position of the sheet metal positioned at the top of the rotating plate 11 can be adjusted. And a supporting circular block 8 is installed outside the rotating column 7 to facilitate bearing the gravity on the rotating column 7. When the rotation position is determined, release the pull rod 3. When the compression spring 4 is released, engage the semi-circular tooth 6 with the rotating tooth 10, so that the rotating column 7 cannot rotate and plays a fixing role.

[0023] A moving groove 12 is opened at the top of the rotating plate 11. A moving plate 13 is slidably connected inside the moving groove 12. A rubber pad 14 is fixedly connected to one side of the moving plate 13. An L-shaped rod 15 is fixedly connected to the other side of the moving plate 13. A straight plate tooth 16 is fixedly connected to the outside of the L-shaped rod 15. A rotating shaft 17 is movably connected inside the rotating plate 11. A transmission tooth 18 is fixedly connected to the outside of the rotating shaft 17. A rocking handle 19 is fixedly connected to the top of the rotating shaft 17. A positioning pin 20 is slidably connected inside the rocking handle 19. The positioning pin 20 is inserted into the rotating plate 11. The straight plate tooth 16 is engaged with the transmission tooth 18.

[0024] When personnel rotate the rocking handle 19, the transmission tooth 18 outside the rotating shaft 17 rotates. When rotating, it meshes with the straight plate tooth 16 on the L-shaped rod 15 for transmission. One side of the L-shaped rod 15 is fixed to the moving plate 13. When personnel rotate the rocking handle 19 clockwise and counterclockwise, the moving plate 13 shortens and extends the distance inside the moving groove 12 to facilitate clamping sheet metals of different widths. The rubber pad 14 can increase the friction force during clamping so as to reduce shaking. By opening perforations on the rotating plate 11, which are equidistantly distributed in a circular array, it is convenient for the positioning pin 20 to be inserted into the perforations to lock the rocking handle 19.

[0025] A fixing frame 21 is fixedly connected to the top of the base 1. A fixed electric block 22 is fixedly connected to one side of the fixing frame 21. A motor 23 is fixedly connected to the top of the fixed electric block 22. One end of the motor 23 is fixedly connected to a threaded rod 24. The threaded rod 24 penetrates through the fixing frame 21 and extends outside the fixing frame 21. A round rod 25 is fixedly connected to the other side of the fixing frame 21. A moving frame 26 is slidably connected to the outside of the round rod 25. The moving frame 26 is threadedly connected to the threaded rod 24. A hydraulic extension rod 27 is slidably connected to the bottom of the moving frame 26. A cutting mechanism 28 is fixedly connected to the bottom of the hydraulic extension rod 27.

[0026] It moves by moving the carriage 26 when the threaded rod 24 rotates. An auxiliary movement is formed by the round rod 25 when the carriage 26 moves, restricting the carriage 26 to convert it into a linear motion. The cutting mechanism 28 can cut the sheet metal by the forward and reverse rotation of the motor 23. The left and right movement of the hydraulic extension rod 27 is controlled by a cylinder at the bottom of the carriage 26, and the cutting mechanism 28 is controlled by the lifting function of the hydraulic extension rod 27 for easy operation.

[0027] A tool box 29 is fixedly connected to the top of the base 1. A cover plate 30 is slidably connected to the top of the tool box 29. A grinding block 31 is fixedly connected to the top of the cover plate 30. A saw tooth box 32 is fixedly connected to the top of the base 1.

[0028] The collection of tools for daily maintenance of the device in the tool box 29 avoids the random placement of tools on the top of the device, which may cause safety hazards. The friction is increased by the grinding block 31 when the personnel open and close the cover plate 30. The saw tooth box 32 facilitates the quick replacement of saw teeth by the personnel.

[0029] Columnar wheels 33 are fixedly connected to the bottom of the base 1. Universal wheels 34 are fixedly connected to the bottoms of the columnar wheels 33.

[0033] The working principle of the sheet metal positioning and cutting device provided by the present utility model is as follows: A pull block 2 is installed on the top of the base 1. By manually pulling the pull rod 3 outwards by a person, the pull rod 3 slides inside the pull block 2. A compression spring 4 is arranged outside the pull rod 3. When the pull rod 3 moves, the distance between the semi-circular block 5 and the pull block 2 shortens. When shortening, the compression spring 4 is squeezed and contracted. A semi-circular tooth 6 is installed outside the semi-circular block 5. A rotating column 7 is rotatably connected to the base 1. A middle groove 9 is opened outside the rotating column 7. A rotating tooth 10 is installed outside the middle groove 9. When the semi-circular tooth 6 disengages from the rotating tooth 10, the rotating column 7 can rotate. When rotating, the rotating plate 11 at the top of the rotating column 7 rotates synchronously, so that the position of the sheet metal positioned on the top of the rotating plate 11 can be adjusted. And a circular supporting block 8 is installed outside the rotating column 7 to facilitate bearing the gravity on the rotating column 7. When the rotating position is determined, the pull rod 3 is released, and when the compression spring 4 is released, the semi-circular tooth 6 is engaged with the rotating tooth 10, so that the rotating column 7 cannot rotate and plays a fixing role, enabling the operator to avoid heavy manual position adjustment and only need to control the rotating position. During the long-term production process, this helps to reduce the fatigue of workers and improve the comfort and safety of work.

[0034] Compared with the related art, the sheet metal positioning and cutting device provided by the present utility model has the following beneficial effects:

[0035] The present utility model provides a sheet metal positioning and cutting device. A rotating mechanism is installed on the top of the device. The rotating mechanism cooperates with each other through the pull block 2, the pull rod 3, the semi-circular block 5, the semi-circular tooth 6, the rotating column 7, and the rotating tooth 10. When the pull rod 3 moves, the compression spring 4 between the pull block 2 and the semi-circular block 5 is compressed, and the semi-circular tooth 6 disengages from the rotating tooth 10 outside the rotating column 7. By this disengagement method, the rotating column 7 rotates. Through the rotating cutting method, the sheet metal can be quickly and accurately adjusted to the required cutting position, reducing the cumbersome positioning and adjustment steps in the traditional cutting method.

[0036] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
