Description

Technical Field

[0001] The utility model relates to the technical field of positioning, in particular to a sheet metal production positioning device for a laser cutting machine. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material; when using laser cutting equipment, a positioning device is required to fix the position of the sheet metal to avoid cutting deviation and error. After searching, a Chinese patent with publication number CN217799653U discloses a sheet metal laser cutting positioning device, including a positioning plate, a slide groove is opened on the lower surface of the positioning plate, and the number of the slide grooves is two, and the upper surface of the positioning plate is fixedly connected to the limit plate, which is released by adding a flip mechanism and a clamping assembly. The two clamping plates can reset the two clamping plates through the resilience of multiple springs themselves, so that the two clamping plates clamp the two ends of the sheet metal, and can quickly fix and clamp the sheet metal, and the cylinder is started to drive the piston rod so that the limit rod on the inner wall of the movable frame slides in the limit groove of the two limit plates, and at the same time the limit rod drives the limit block to make the movable seat flip inside the two limit plates, and the movable seat drives the material plate to tilt when flipping, and pours the sheet metal waste into the inside of the waste box, so that the positioning device is convenient for collecting waste. However, it is necessary to release the clamping mechanism before discharging the waste, and the clamping mechanism cannot be released at the same time as the flipping, which makes the operation cumbersome and reduces the processing efficiency.

The laser cutting machine uses sheet metal production positioning device, which is convenient for releasing the clamping mechanism while flipping, so that the waste can be poured out smoothly, reducing the operation steps and further improving the processing efficiency.

DETAILED DESCRIPTION

[0021] 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.

[0022] Example:

[0023] See also Figure 1-6 A sheet metal production positioning device for a laser cutting machine includes a base frame 1, a clamping structure is arranged above the base frame 1, the clamping structure includes a clamping frame 3 and a guide frame 2 arranged above and below, a guiding elastic mechanism is arranged between the guide frame 2 and the clamping frame 3, and also includes a flipping mechanism arranged on the base frame 1 and used to drive the clamping frame 3 to flip, and support mechanisms compatible with the clamping frame 3 are arranged on both sides of the flipping mechanism.

[0024] Specifically, the flipping mechanism includes a support bar fixedly mounted on the base frame 1, a rotating shaft fixedly connected to the bottom of the guide frame 2 and rotatably connected to the top of the support bar, a rotating motor 7 is installed on the base frame 1, and the output shaft of the rotating motor 7 is connected to the rotating shaft through a sprocket chain 8. When the rotating motor 7 is started, the output shaft of the rotating motor 7 rotates clockwise or counterclockwise, and the transmission cooperation of the sprocket chain 8 facilitates the driving of the rotating shaft and the guide frame 2 to rotate clockwise or counterclockwise as a whole.

[0025] Specifically, the supporting mechanism includes a supporting seat 6 fixedly mounted on the base frame 1, the top of the supporting seat 6 is rotatably connected to a supporting roller 4, and the side wall of the clamping frame 3 is fixedly connected to a slide plate 5 located above the supporting roller 4. Through the cooperation of the supporting seat 6, the supporting roller 4 and the clamping frame 3, when the clamping structure rotates as a whole, the clamping frame 3 is pushed out to the side away from the guide frame 2 through the supporting roller 4, so that the guide frame 2 and the clamping frame 3 are opened a certain distance.

[0026] Specifically, the guiding elastic mechanism includes four groups and is respectively arranged at the four corners of the guiding frame 2 and the pressing frame 3. The guiding elastic mechanism includes a lower fixed block 9 and an upper fixed block 10 respectively fixedly installed on the guiding frame 2 and the pressing frame 3. The lower fixed block 9 is slidably matched with a guide rod 11 fixedly connected to the upper fixed block 10 at the top. The bottom of the guide rod 11 is fixedly connected to a limiting block 12. A spring 13 is sleeved on the guide rod 11. The top and bottom ends of the spring 13 are respectively fixedly connected to the lower fixed block 9 and the limiting block 12. Through the cooperation of the lower fixed block 9, the upper fixed block 10, the guide rod 11, the limiting block 12 and the spring 13, it is convenient to press the pressing frame 3 onto the guide frame 2.

[0027] Specifically, it also includes a material receiving box 14 arranged under the guide frame 2, and storage boxes 15 placed on the base frame 1 are arranged on both sides of the material receiving box 14. The material receiving box 14 is used to facilitate the collection of the cut finished products. Through the two storage boxes 15, one storage box 15 can be used as a container for recycling waste materials, and the other storage box 15 can be used to store material plates to be processed.

[0028] When in use, the clamping structure is first driven to rotate to one side by the flipping mechanism. As it rotates, the supporting mechanism lifts the pressing frame 3 to the side away from the guide frame 2, and then pushes the material plate between the guide frame 2 and the pressing frame 3. Then, the clamping structure is driven to rotate to a horizontal state by the flipping mechanism. As it rotates, the outward thrust of the supporting mechanism on the pressing frame 3 is slowly released, so that under the action of the guiding elastic mechanism, the material plate is clamped and fixed between the guide frame 2 and the pressing frame 3. Then, a laser cutting machine is used to cut the material plate clamped between the guide frame 2 and the pressing frame 3. The cut product falls down after cutting. Then, the clamping structure is driven to rotate to the other side by the flipping mechanism, and the pressing frame 3 is pushed to the side away from the guide frame 2 by the supporting mechanism, so as to contact the pressing frame 3 and the guide frame 2 to clamp the waste. Then, under the action of the waste's own gravity, the waste slides out, and the above operation is repeated.
