Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a device for automatically adjusting a laser safety protection mechanism. Background Technology

[0002] In the bending machine manufacturing process, workers frequently need to put their hands into the dangerous areas of the equipment to perform bending operations. If the equipment lacks effective protective measures, accidents can easily occur, leading to injuries. To ensure worker safety and improve production efficiency, a safety protection technology capable of real-time monitoring of dangerous areas and taking timely measures before danger occurs is needed; this is where safety light curtains come in. When processing a variety of parts, and different parts require different heights or shapes of upper blades depending on the bending process requirements, the height of the corresponding laser safety protection mechanism also needs to be adjusted when the height of the upper blade changes. When the upper blade is frequently changed during production, the height of the corresponding laser safety protection mechanism also needs to be repeatedly adjusted. When the machine tool is equipped with automated bending, and the machine tool needs to change the upper blade when different production programs are selected, the laser safety protection mechanism must be manually lifted before the subsequent upper blade change operation can be completed.

[0003] Therefore, it is necessary to design a device that can be controlled by a CNC system to automatically and quickly adjust the height of the laser safety protection mechanism. Summary of the Invention

[0019] See Figure 1-5 This embodiment is a device for automatically adjusting a laser safety protection mechanism, including a bracket 4, a servo motor 6 mounted on the upper end of the bracket 4, a support 8 mounted on the lower end of the bracket 4, a guide rail 13 arranged along the length direction inside the bracket 4, a lead screw 5 mounted on the support 8, the lower end of the lead screw 5 being rotatably connected to the support 8, and the upper end of the lead screw 5 being connected to the servo motor 6, a slide 7 mounted on the guide rail 13, the slide 7 being threadedly connected to the lead screw 5, a support arm 12 connected to one side of the slide 7, the support arm 12 being connected to the side of the slider 1 of the bending machine, and a laser safety protection mechanism 10 mounted on the support 8; the servo motor 6 is signal-connected to the main control system of the bending machine.

[0020] Furthermore, the support 8 is provided with a horizontally arranged track, an adjustment frame 9 is mounted on the track, a locking screw 15 is mounted on the adjustment frame 9, and the laser safety protection mechanism 10 is installed at the bottom of the adjustment frame 9.

[0021] Furthermore, the adjustment frame 9 has an adjustment hole A16 corresponding to the rear end of the laser safety protection mechanism 10, and two adjustment holes B17 corresponding to the rear end of the laser safety protection mechanism 10. Both adjustment holes A16 and adjustment holes B17 are equipped with screws 14. The bottom end of each screw 14 is fixedly connected to the outer shell of the laser safety protection mechanism 10. Adjusting nuts are installed on the upper and lower sides of each screw 14 at the adjustment holes A16 and B17.

[0022] Furthermore, the adjustment hole A16 is a round hole, and the two adjustment holes B17 are both arc-shaped holes with the center of adjustment hole A16 as the center, and the two adjustment holes B17 are arranged symmetrically.

[0023] Furthermore, the track is a track groove 81, and a sliding key 11 is installed in the track groove 81. The shape of the sliding key 11 matches the track groove 81, and the sliding key 11 has a through threaded hole. The locking screw 15 is threadedly connected to both the adjusting bracket 9 and the sliding key 11.

[0024] See Figure 6 , Figure 7The working principle of this utility model is as follows: When the parts processed by the bending machine are switched, mold A2 needs to be switched to mold B3. At this time, the height of the laser safety protection mechanism 10 is at the height position corresponding to the tool A. The main control system issues a mold change command. The servo motor 6 receives the command and drives the lead screw 5 to rotate. Since the slide 7 is connected and fixed to the slider 1 through the support arm 12, the lead screw 5 will drive the entire bracket 4 and the lower laser safety protection mechanism 10 to move upward relative to the support arm 12 until it reaches the zero position. At this time, mold A2 can be moved out from the side of the slider 1 without colliding with the laser safety protection mechanism 10. Then, mold B3 is moved into the mounting slot of the slider 1. After mold B3 is installed, the main control system issues a command to the servo motor 6. The servo motor 6 moves the laser safety protection mechanism 10 from the zero position to the height position corresponding to the mold B3, thereby realizing the automatic adjustment of the height of the laser safety protection mechanism 10.

[0025] This utility model uses the adjustment frame 9 to center and adjust the laser safety protection mechanism 10. By loosening the locking screw 15, the adjustment frame 9 can move along the track groove 81 of the support 8 via the sliding key 11, thereby realizing the adjustment of the laser safety protection mechanism 10 in the X direction. Since the two adjustment holes B17 at the front end of the adjustment frame 9 are arc-shaped holes, by adjusting the position of the screws 14 in these two adjustment holes B17, the laser safety protection mechanism 10 can be rotated at a certain angle in the horizontal plane. By adjusting the relative length of each screw 14 in the adjustment hole A16 and adjustment hole B17, the laser safety protection mechanism 10 can be rotated in the vertical plane. Ultimately, the centering adjustment of the laser safety protection mechanism 10 is achieved according to the actual situation.
