Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a sheet metal part bending positioning device. Background Art

[0002] Sheet metal bending refers to the process of bending a metal sheet into a desired shape at a certain angle by mechanical or manual operation. This process usually requires the use of a bending machine or bending tool to fix the metal sheet in the appropriate position, and then apply force to bend it. During the sheet metal bending process, the positioning device can help fix and stabilize the metal sheet, ensure its accurate position when applying the bending force, and avoid inaccurate size or shape distortion after bending due to movement or deformation.

[0003] Traditional positioning devices usually consist of fixtures, clamping devices and positioning blocks. The fixture is used to fix the metal sheet to ensure its stable position; the clamping device is used to apply force to fix the metal sheet in the desired position; the positioning block is used to determine the position of the metal sheet, usually in conjunction with the fixture to ensure the accuracy of the bending position.

[0004] However, traditional positioning devices can generally only effectively position and clamp workpieces of the same size. If sheet metal parts of different sizes or shapes need to be processed, the positioning device may need to be frequently replaced, increasing the operation time and cost in the production process. In addition, for workpieces with complex shapes, traditional positioning devices may not provide sufficient accuracy and stability, resulting in position deviation or shape distortion during the bending process, reducing processing efficiency.

[0008] Furthermore, a slide groove is provided inside the fixing platform, and the positioning rod is slidably connected inside the slide groove.

[0009] Furthermore, a fixing frame is fixedly connected to the top of the fixing platform, a cylinder is fixedly connected to the top of the fixing frame, and a pressure block is fixedly connected to the output end of the cylinder.

[0011] Furthermore, a handle is fixedly connected to the outer wall of the screw, and a fixing block is fixedly connected to the outer wall of the threaded rod.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a sheet metal bending positioning device, including a fixed platform 1, a plurality of support blocks 2 are fixedly connected inside the fixed platform 1, one side of one of the support blocks 2 is fixedly connected to a motor 3, the output end of the motor 3 is fixedly connected to a rotating wheel 1 4, one side of another support block 2 is rotatably connected to a rotating wheel 2 5, a synchronous belt 6 is arranged between the rotating wheel 1 4 and the rotating wheel 2 5, a guide rail 7 is fixedly connected inside the fixed platform 1, and the outer wall of the guide rail 7 is slidably connected to two left-right symmetrical connecting frames 8, one of the connecting frames 8 is fixedly connected to a connecting block 1 9, A connecting block 1 9 is internally fixedly connected to one side of the synchronous belt 6, a connecting block 2 10 is internally fixedly connected to another connecting frame 8, and the connecting block 2 10 is internally fixedly connected to the other side of the synchronous belt 6. A positioning assembly is arranged on the top of the connecting frame 8, and the positioning assembly includes a positioning rod 11, and the bottom end of the positioning rod 11 is fixedly connected to the top of the connecting frame 8. A slide groove 12 is provided inside the fixed platform 1, and the positioning rod 11 is slidably connected inside the slide groove 12. A fixed frame 13 is fixedly connected to the top of the fixed platform 1, and a cylinder 14 is fixedly connected to the top of the fixed frame 13, and a pressure block 15 is fixedly connected to the output end of the cylinder 14.

[0025] Specifically, when using the positioning device, the sheet metal is first placed on the top of the fixed table 1. Subsequently, the motor 3 drives the rotating wheel 4 to move through the output end, thereby promoting the movement of the synchronous belt 6 on the outer wall. This movement process simultaneously drives the movement of the rotating wheel 2 5 and the connecting block 1 9. The connecting block 1 9 is subjected to the force of the synchronous belt 6, thereby driving the connecting frame 8 fixed at the bottom to slide on the outer wall of the guide rail 7. At the same time, the synchronous belt 6 also moves the connecting block 2 10 on the other side toward the direction of the connecting block 1 9 to ensure that the connecting blocks on both sides work together. The coordinated movement of the connecting block 1 9 and the connecting block 2 10 allows the connecting frame 8 to slide smoothly on the guide rail 7. The precise design of this motion system ensures the stability and accuracy of the connecting frame 8. Finally, the positioning rod 11 fixed on the top accurately positions the sheet metal by sliding inside the slide groove 12, thereby achieving the effect of positioning sheet metal parts of different sizes.

[0026] Reference Figure 1 and Figure 4 A threaded rod 16 is slidably connected inside the fixed platform 1, a screw 18 is threadedly connected to the outer wall of the threaded rod 16, a handle 19 is fixedly connected to the outer wall of the screw 18, and a fixing block 17 is fixedly connected to the outer wall of the threaded rod 16.

[0027] Specifically, after positioning is completed, subsequent operations can be performed by turning the handle 19. The handle 19 is subjected to force, driving the screw 18 fixedly connected on one side to rotate on the outer wall of the threaded rod 16. The threaded connection between the screw 18 and the threaded rod 16 causes the screw 18 to move, and finally the screw 18 is moved to the top of the fixing block 17 to tighten it. This step enables the clamping block 22 to press and fix the sheet metal part, ensuring that the position of the workpiece remains unchanged during the subsequent processing.

[0028] Reference Figure 1 and Figure 4 A rotating rod 21 is fixedly connected to the bottom of the fixed block 17, a rotating block 20 is rotatably connected inside the rotating rod 21, the rotating block 20 is in contact with the fixed platform 1, and a clamping block 22 is fixedly connected to one side of the rotating rod 21.

[0029] Specifically, if the height of the fixing assembly needs to be adjusted, it can be achieved by rotating the rotating block 20. According to the needs, the high or low side of the rotating block 20 is rotated to the top of the fixing table 1, and then the clamping block 22 is driven to press on the plate by rotating the screw 18. This design effectively realizes the reliable fixation of plates of different thicknesses and improves the accuracy and efficiency of processing.

[0030] Working principle: When using the positioning device, first place the sheet metal on the top of the fixed platform 1, and drive the rotating wheel 4 to move through the output end of the motor 3. The rotating wheel 4 is driven by the force to drive the synchronous belt 6 set on the outer wall to move, and the synchronous belt 6 drives the rotating wheel 2 5 to rotate. At the same time, the synchronous belt 6 drives the connecting block 1 9 fixed on one side to move. The connecting block 1 9 is driven by the force to drive the connecting frame 8 fixed at the bottom to slide on the outer wall of the guide rail 7. At the same time, the synchronous belt 6 also drives the connecting block 2 10 fixed on the other side to move in the same direction as the connecting block 1 9. Through the movement of the connecting block 1 9 and the connecting block 2 10, the connecting frame 8 drives the positioning rod 11 fixed on the top to slide inside the slide groove 12, and through the fixed The positioning rod 11 positions the sheet metal, thereby achieving the effect of positioning sheet metal parts of different sizes. After the positioning is completed, the handle 19 can be turned, and the handle 19 is driven by force to drive the screw 18 fixedly connected on one side to rotate on the outer wall of the threaded rod 16, and the screw 18 is moved through the threaded connection between the threaded rod 16 and the screw 18. The screw 18 moves to the top of the fixed block 17 to fix it, and then the clamping block 22 presses and fixes the sheet metal. When the height of the fixed component needs to be adjusted, the rotating block 20 is rotated to rotate the high or low side of the rotating block 20 to the top of the fixed platform 1 according to the needs, and then the screw 18 is turned to drive the clamping block 22 to press on the plate, thereby achieving the effect of fixing plates of different thicknesses.
