Description

Technical Field

[0001] This utility model relates to the field of bending machine processing technology, specifically a driving device for a laser inspection camera. Background Technology

[0002] Bending machines are widely used machine tools in the machining industry. The angle of the workpiece to be bent varies significantly due to factors such as material thickness differences, machine tool deflection, and die wear, failing to meet drawing requirements. Therefore, real-time angle detection is necessary during the bending process. Currently, laser camera detection technology is relatively advanced. For example, patent document CN117046930A discloses the use of a laser angle detector to detect the angle of bent workpieces. One detector is installed on each side of the lower die of the bending machine. However, in actual production, the following problems exist: when the workpiece is long, multi-point detection is required. In this case, the camera needs to move back and forth along the length of the die, and the cameras on both sides of the workpiece must be synchronized; otherwise, the detection results will be inaccurate. Therefore, a driving device needs to be designed to synchronously move the laser detection cameras on both sides to the designated position for detection. Summary of the Invention

[0018] See Figure 1-4This embodiment is a driving device for a laser inspection camera 1, including two linear tracks 8 set on both sides of the bending machine frame. Each of the two linear tracks 8 is equipped with a set of sliding brackets 2 for mounting the laser inspection camera 1. One end of each linear track 8 is provided with a driving mechanism, which includes a servo motor 3 and a reducer 4. The output end of the reducer 4 is provided with a drive shaft 5 extending to both sides. Each end of the drive shaft 5 is equipped with a drive wheel 6. The other end of each of the two linear tracks 8 is provided with a transmission wheel. A synchronous belt 13 with cyclic motion is wound between each drive wheel 6 and the corresponding guide wheel. The synchronous belt 13 is connected to the sliding bracket 2 on the corresponding side.

[0019] Furthermore, the sliding bracket 2 includes a bracket body, within which a camera receiving cavity 23 is provided. A camera mounting plate 24 is provided inside the camera receiving cavity 23. An opening is provided at the top of the camera receiving cavity 23. A slide block 28 and a drive connector are provided on one side of the bracket body. The slide block 28 cooperates with the linear track 8. The drive connector includes a toothed plate 27 and a pressure plate 26. The toothed plate 27 matches the transmission teeth of the synchronous belt 13. The pressure plate 26 is located directly above the toothed plate 27. The pressure plate 26 is provided with several set screw holes for installing set screws that press the synchronous belt 13.

[0020] Furthermore, the bracket body includes two side plates 29, with a sliding block 28 connecting plate 25 installed on one side between the two side plates 29, a back plate on the other side, and a top plate 22 at the top between the two side plates 29.

[0021] Furthermore, the camera mounting plate 24 is installed at an angle between the two side plates 29 by bolts, and the angle of inclination is set according to the actual needs of the machine tool.

[0022] Furthermore, one end of the linear track 8 is equipped with a tensioning wheel 7 mechanism, which includes an adjusting block 14. Each side of the adjusting block 14 is provided with a tensioning wheel 7 corresponding to the two synchronous belts 13. The tensioning wheel 7 is used to press the synchronous belt 13. One end of the adjusting block 14 is connected to an adjusting bolt, which is used to adjust the position of the adjusting block 14, thereby pressing the synchronous belt 13 through the tensioning wheel 7, so that the synchronous belt 13 accurately transports the sliding bracket 2 to the designated position.

[0023] Furthermore, both sides of the bending machine frame are provided with drag chain grooves 9 below the straight track 8, and drag chain 10 is installed in the drag chain grooves 9. The drag chain 10 is connected to the sliding bracket 2. The two sides of the frame are also provided with drag chain 10 support rollers, which are used to support the suspended part of the drag chain 10.

[0024] The cable chain 10 contains a connection cable to the laser detection camera 1. When the sliding bracket 2 is far from the cable chain groove 9, the suspended cable chain 10 is supported by the cable chain 10 roller.

[0025] Furthermore, each end of the linear track 8 is provided with a limit switch 12, and the limit switches 12 are both connected to the main control system signal.

[0026] The working principle of this utility model is as follows: The servo motor 3 is connected to the main control system of the bending machine. The system sends a signal to the servo motor 3 according to the length and position of the workpiece to be detected. The servo motor 3 acts according to the command and drives the synchronous belts 13 on both sides through the drive shaft 5. The synchronous belts 13 on both sides drive the corresponding sliding brackets 2 to move to the designated position. The laser detection cameras 1 on both sides move to the detection point together with the sliding brackets 2. When the sliding brackets 2 move, they are limited by the limit switches 12 at both ends of the linear track 8. When any limit switch 12 detects the sliding bracket 2, the limit switch 12 will automatically send a signal to the system. The system controls the servo motor 3 to stop immediately to ensure operational safety.
