Description

Technical Field

[0001] The present invention relates to the field of stamping production technology, and in particular to a burr cleaning and detection device for sheet workpieces used in intelligent manufacturing of punching machines. Background Art

[0002] For general punching machines, the stamping process involves extruding and cutting a workpiece through a die, causing plastic deformation or separation, thereby obtaining the desired shape and size. Stamping blanks are primarily hot-rolled and cold-rolled steel sheets and strips. Stamping parts typically have varying degrees of burrs. Burr height exceeding a certain range can affect product quality, necessitating inspection and polishing of these parts. Burr detection typically involves direct touch, which can easily scratch the skin. Manual inspection requires constant operation, resulting in low efficiency. Prolonged polishing and observation of the stamped sheet surface can cause eye strain and lead to certain detection errors. Therefore, under the wave of intelligent manufacturing, punching equipment is evolving toward higher efficiency, precision, and versatility, with increasing automation levels. We propose a burr removal and detection device for sheet workpieces used in intelligent punching manufacturing to address these issues. Summary of the Invention

[0026] Example

[0027] like Figure 1-7As shown, an embodiment of the present invention proposes a burr cleaning and detection device for sheet workpieces used in intelligent manufacturing of punching machines, including an operating table 1, a punching machine component 2 is installed on the top of the operating table 1, a detection platform column 3 is fixed on the top of the operating table 1, a support arm 4 is provided on one side of the detection platform column 3, a lifting component 5 for adjusting the height of the support arm 4 is provided on the top of the operating table 1, a main rotating shaft 6 is rotatably installed on the middle part of the top of the support arm 4 through a bearing, and the distance between the end of the main rotating shaft 6 and the lower surface of the support arm 4 is 3 cm-10 cm, and a driving component 7 for driving the main rotating shaft 6 to rotate back and forth is provided on the top of the operating table 1, a connecting block 8 is fixed on the top of the main rotating shaft 6, and a detection rod 9 is rotatably installed on the middle part of the connecting block 8 through a bearing, and a cleaning plate 10 and a detection plate 11 are fixed on the surface of the detection rod 9, one side surface of the cleaning plate 10 is a rough surface, and one side surface of the detection plate 11 is a smooth surface, and the rough surface of the cleaning plate 10 and the smooth surface of the detection plate 11 are arranged opposite to each other. The end of the detection rod 9 is fixed with a round block 12, and an elastic limit swing rod 13 is fixed to one end surface of the round block 12. The elastic limit swing rod 13 is made of spring steel. A limit sliding ball 14 is installed at the bottom end of the elastic limit swing rod 13. A limit slide 15 adapted to the limit sliding ball 14 is fixed to the surface of the support arm 4. One end of the limit slide 15 is arc-shaped, and the middle of the limit slide 15 is concave and the two sides are convex. The other end surface of the round block 12 is fixed. There is a U-shaped insulating sleeve 16, a fine-tuning screw 17 is installed on the top of the U-shaped insulating sleeve 16, the top of the fine-tuning screw 17 is fixedly connected to the No. 1 wire 18, a U-shaped insulating frame 19 is fixed on the top of the connecting block 8, an electrode contact rod 20 is fixed inside the U-shaped insulating frame 19, one end of the electrode contact rod 20 is fixedly connected to the No. 2 wire 21, a feedback light 22 is fixed on the top of the operating table 1, and the No. 1 wire 18 and the No. 2 wire 21 are respectively connected to the positive and negative ends of the feedback light 22.

[0028] When in use, first place the blank workpiece on the punch assembly 2 to punch out the parts, then turn the parts over and place them on the inspection platform column 3. At this time, the burr surface of the part is facing upward, and then use the lifting assembly 5 to adjust the height of the support arm 4 so that the cleaning plate 10 and the inspection plate 11 are above the workpiece, and then use the driving assembly 7 to drive the main shaft 6 to rotate back and forth. The main shaft 6 drives the inspection rod 9 to rotate back and forth through the connecting block 8. The rear end of the inspection rod 9 drives the elastic limit swing rod 13 to slide in the limit slide 15 through the round block 12. The inspection rod 9 follows the main shaft 6 in the initial swing process. At this moment, the U-shaped insulating sleeve 16 drives the fine-tuning screw 17 to depart from the electrode contact rod 20. At the same time, the inspection rod 9 drives the cleaning plate 10 to swing in the direction of the burr surface of the workpiece.

The inspection rod 9 As the main rotating shaft 6 is in the process of resetting and swinging, the U-shaped insulating sleeve 16 drives the fine-tuning screw 17 to be opposite to the electrode contact rod 20. When the detection rod 9 drives the detection plate 11 to swing in the direction of the burr surface of the workpiece, during this process, when the protruding burr of the workpiece is too high to meet the processing requirements, when the detection plate 11 passes over the burr surface on the workpiece, the burrs on the workpiece will cause the detection plate 11 to drive the detection rod 9 to lift at different angles. During this process, the angle at which the detection rod 9 is lifted causes the No. 1 wire 18 and the No. 2 wire 21 between the electrode contact rod 20 and the fine-tuning screw 17 to form a closed circuit, that is, the feedback light 22 lights up at this moment, which means that the workpiece is judged to be unqualified. During the detection process, the distance between the No. 1 wire 18 and the electrode contact rod 20 can be adjusted by the fine-tuning screw 17, thereby adjusting the detection plate 11 to drive the detection rod 9 to lift at different angles, thereby adapting to the burr height requirements of different workpieces.
