[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5In this embodiment of the invention, an auxiliary positioning device for precision sheet metal processing includes a base frame 1. Guide frames 2 are fixedly connected to both sides of the top of the base frame 1. A fixed frame 3 is slidably connected between the two guide frames 2. A displacement cylinder is provided on one side of the fixed frame 3 to push the fixed frame 3 to slide along the length direction of the guide frames 2. The output end of the displacement cylinder is fixedly connected to the fixed frame 3. An electric gripper 5 for positioning and fixing the end of the sheet metal material is fixedly installed on the inner wall of the fixed frame 3. Guide grooves are provided on the sides of the two guide frames 2 that are close to each other. By setting the displacement cylinder to drive the fixed frame 3 to move, and cooperating with the electric gripper 5 set on the inner wall of the fixed frame 3, the end of the sheet metal material is clamped and fixed. The movement of the fixed frame 3 drives the sheet metal material to move, assisting in the feeding operation of the sheet metal material.

[0025] To facilitate the adjustment of the sheet metal material's position during processing, adjustable slide rails 17 are fixedly installed at the bottom of both guide frames 2. Several support units for supporting the sheet metal material are slidably connected between the two adjustable slide rails 17. Each support unit includes a roller frame 12, with its top two ends slidably connected to the inner walls of the two adjustable slide rails 17. A support roller 13 is rotatably mounted on the inner wall of the roller frame 12, and a roller motor 14 is fixedly installed on one side of the roller frame 12. The output end of the roller motor 14 is fixedly connected to one end of the support roller 13. By setting the support roller 13, the processing position of the sheet metal material is supported, improving the stability of the sheet metal material's posture during processing. Due to the slidable connection of the roller frame 12, the position of each support roller is flexibly adjustable, allowing the sheet metal material to be supported at different positions according to the needs of the processing position. Combined with the rotation of the roller motor 14, the position of the sheet metal material can be flexibly adjusted.

[0026] To ensure stable clamping of the sheet metal end by the electric gripper 5, several contact switches 6 are embedded on one side of the inner wall of the electric gripper 5, and several indicator lights 7 are fixedly installed on the top of the fixing frame 3. The contact switches 6 are respectively set and electrically connected to the indicator lights 7. The position of the sheet metal is detected by the contact of each contact switch 6 with the end of the sheet metal, so as to ensure the stability of the position and posture of the end of the sheet metal.

[0027] A detection unit for detecting the condition of sheet metal is fixedly installed on the top of the guide frame 2. The detection unit includes a drive guide rail 8, and the detection unit for detecting the condition of sheet metal is slidably installed on the inner wall of the drive guide rail 8. The detection unit includes a drive plate, and a detection frame 9 is fixedly connected to the top of the drive plate. An upper positioning groove 10 is opened on the top of the detection frame 9, and an upper docking frame 11 is slidably connected to the inner wall of the upper positioning groove 10. A positioning plate 15 is fixedly connected to one side of each of the several rotating roller frames 12. The top of the positioning plate 15 is opened... A lower positioning slide groove is provided, and several lower docking frames are slidably connected to the inner wall of the lower positioning slide groove. The lower docking frames are correspondingly set with the upper docking frame 11. Photoelectric gates 16 are fixedly installed on both the upper docking frame 11 and the lower docking frame. The transmitting end and receiving end of the same photoelectric gate 16 assembly are respectively located on the corresponding upper docking frame 11 and the lower docking frame. By setting the corresponding arrangement of several photoelectric gates 16 on the upper docking frame 11 and the lower docking frame, the detection of the position of the through hole on the sheet metal material is realized, thereby realizing the accurate positioning of the sheet metal material.

[0028] To further improve the positional stability of sheet metal during processing, a connecting plate is fixedly connected to the bottom of the inner wall of the inspection frame 9, and a contact plate 18 is fixedly connected to one side of the connecting plate. The edge of the contact plate 18 is inclined downward. To facilitate the determination of the position of the sheet metal, scale lines are painted on the top of the contact plate 18.

[0029] The inner wall of the inspection frame 9 is provided with a sliding groove, and a pressing adjustment component is slidably installed on the inner wall of the sliding groove. The pressing adjustment component includes a sliding plate 26, and a flipping frame 20 is fixedly connected to the top of the sliding plate 26. An adjusting roller 19 is rotatably installed on the inner wall of the flipping frame 20. An adjusting motor 22 is fixedly installed on one side of the flipping frame 20. The output end of the adjusting motor 22 is fixedly connected to the adjusting roller 19. Several contact washers 21 are fixedly connected to the outer wall of the adjusting roller 19. A locking bolt is threadedly connected to the middle of the sliding plate 26. By setting up the flipping frame 20 and the adjusting roller 19, the sheet metal is pressed and pushed from above, giving the sheet metal an additional force support point, making the position of the sheet metal more stable. With the adjustment motor 22 driving the adjusting roller 19 to rotate, the posture of the sheet metal is adjusted.

[0030] Both guide troughs are equipped with lateral positioning units on their inner walls. Each lateral positioning unit includes a movable plate 23 slidably connected to the bottom of the inner wall of the guide trough. A side support plate 24 is slidably connected to the top of the movable plate 23. Several side guide wheels 25 are rotatably connected to the top of the side support plate 24. Several fixing bolts are rotatably connected to one side of the side support plate 24. By setting the lateral positioning units, the two sides of the sheet metal are guided and limited, so that the device can meet the positioning needs of sheet metal of different widths. In use, the position of the side support plate 24 can be slidably adjusted according to the width of the sheet metal, and then locked by fixing bolts. The side guide wheels 25 are used to guide the two sides of the sheet metal.

[0031] When using this invention, firstly, the positions of the sliding roller frame 12 and the lower docking frame are adjusted so that the photoelectric gate 16 on the lower docking frame is aligned with the through hole or pre-drilled hole on the sheet metal. Then, the position of the upper docking plate is adjusted by sliding, and the detection frame 9 is moved by the drive guide rail 8 so that the photoelectric gate 16 on the upper docking frame 11 is aligned with the photoelectric gate 16 on the lower docking frame, so that the photoelectric gate 16 is turned on.

[0032] If the sheet metal being processed is a straight sheet, its end is fed into the guide groove. The rotating support roller 13 adjusts and pushes the sheet metal until its end enters the fixed frame 3 and contacts each contact switch 6. Each contact switch 6 in contact with the sheet metal illuminates its corresponding indicator light 7. The operator judges the position and orientation of the sheet metal based on the illuminated indicator lights 7 to ensure correct orientation. At this time, the through holes or pre-drilled holes on the sheet metal should be aligned with the photoelectric gate 16 to achieve accurate positioning of the sheet metal. The support roller 13 is located near the through holes or pre-drilled holes, providing support during sheet metal processing. Then, the electric gripper 5 is activated to clamp the end of the sheet metal. The external sheet metal processing equipment then processes the sheet metal. After processing, the electric gripper 5 opens, and the support roller 13 is activated to send the sheet metal out.

[0033] If the sheet metal being processed is cylindrical, adjust the position of the roller frame 12 so that the two supporting rollers 13 are close to each other and the distance between them is less than the diameter of the sheet metal. Then place the sheet metal between the two supporting rollers 13, and the drive guide rail 8 drives the detection frame 9 to move and flip the adjustment frame 20 so that the adjusting roller 19 contacts the sheet metal, thereby achieving the pressing and support of the sheet metal. Then the processing operation is performed by the external processing equipment. By adjusting the drive of the motor 22, the adjusting roller 19 is driven to rotate, which in turn drives the sheet metal to rotate, thereby achieving the adjustment of the sheet metal posture and making the processing operation more convenient.
