Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a laser cutting device for sheet metal processing. Background Technology

[0002] Sheet metal work is a comprehensive cold-working process for thin metal sheets (usually less than 6mm thick), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal work are called sheet metal parts. The term "sheet metal part" generally varies across different industries and is often used in assembly contexts.

[0003] The laser cutting device for sheet metal processing disclosed in CN 217193322 U uses a fixed frame, a movable rod, a compression spring a, a clamping plate, an extrusion plate, and a compression spring b to fix the sheet metal parts in place, preventing them from shifting due to external factors and thus affecting the cutting position of the laser cutting head.

[0004] This laser cutting device for sheet metal processing uses an internal clamping plate to press the sheet metal parts to be processed, making them more stable during processing. However, the clamping mechanism of this device is fixed and it is difficult to provide stable clamping for sheet metal parts of different sizes, especially different widths. At the same time, the movement range of its laser cutting head is limited, which cannot meet the processing needs of large-sized sheet metal parts. Therefore, it needs to be improved. Summary of the Invention

The fixed rod is fixedly connected to the top of the processing table. A first short rod is rotatably connected to the middle of the inside of the rotating plate. A first arc-shaped plate is fixedly connected to the front and rear of the first short rod. The first arc-shaped plate is fixedly connected to the left side of the processing table.

An electric telescopic rod is fixedly connected to the top left side of the clamping plate. A moving plate is fixedly connected to the left side of the electric telescopic rod, and a sliding plate is fixedly connected to the right side of the moving plate. The sliding plate is slidably connected to the inside of the clamping plate. A first threaded rod is threadedly connected inside the moving plate, and an anti-slip plate is fixedly connected to the bottom of the first threaded rod. The moving mechanism includes a pad plate, which is fixedly connected to the back end of the processing table. A first motor is fixedly connected to the left side of the pad plate, and a worm gear is fixedly connected to the left side of the first motor. A worm wheel meshes with the bottom of the worm gear, and a rotating rod is fixedly connected inside the worm wheel. The front of the rotating rod is rotatably connected to the inside of the processing table. A rotating disk is fixedly connected to the back end of the rotating rod, and an arc-shaped block is fixedly connected to the back end of the rotating disk. A second short rod is fixedly connected to the top of the back end of the rotating disk. A second linkage plate is slidably connected to the periphery of the second short rod, and a sliding block is slidably connected to the bottom of the second linkage plate. A third short rod is rotatably connected inside the sliding block, and the third short rod is fixedly connected to the bottom of the back end of the processing table. The adjustment mechanism includes a push rod, which is rotatably connected to the top of the second linkage plate. A moving block is fixedly connected to the front of the push rod, and a moving frame is fixedly connected to the top of the moving block. A support block is fixedly connected to the front of the bottom of the moving frame, and the support block is slidably connected to the top of the processing table. A second motor is fixedly connected to the top of the back end of the moving frame, and a second threaded rod is fixedly connected to the front of the second motor. The front of the second threaded rod is rotatably connected to the front of the inside of the moving frame, and a threaded block is threadedly connected to the outer periphery of the second threaded rod. A laser cutter is fixedly connected to the bottom of the threaded block.

[0007] According to the above technical solution, the rotating plate has a hole inside that corresponds to the size of the first short rod, and the first short rod is rotatably connected inside the hole, so that the first short rod can limit the rotating plate and allow the rotating plate to rotate through the first short rod.

[0008] According to the above technical solution, a fixed groove corresponding to the size of the slider is opened on the top of the processing table, and the slider is slidably connected to the inside of the fixed groove. The fixed groove can limit the slider, so that the rotating plate can drive the slider to move through the push plate during the rotation. When the slider moves, the fixed groove can limit the slider, making the slider more stable during the movement.

[0009] According to the above technical solution, the back end of the processing table is provided with a circular groove corresponding to the movement trajectory of the arc-shaped block, and the arc-shaped block is slidably connected inside the circular groove. The arc-shaped block can support and limit the rotation of the disk, making the disk more stable during rotation.

[0010] According to the above technical solution, a sliding groove corresponding to the size of the moving block is opened at the top back end of the processing table, and the moving block is slidably connected inside the sliding groove, so that the second linkage plate can drive the moving block to move through the push rod during the rotation, so that the moving block can move inside the sliding groove. The sliding groove can limit the moving block, making the moving block more stable during the movement.

[0011] According to the above technical solution, the movable frame has a limiting groove inside that corresponds to the movement trajectory of the threaded block, and the threaded block is slidably connected inside the limiting groove. The limiting groove can limit the movement of the threaded block, making the threaded block more stable during the movement when the second threaded rod drives the threaded block to move.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This laser cutting device for sheet metal processing, through a set drive clamping mechanism, when it is necessary to clamp the sheet metal part, opens the dual-axis cylinder, so that the dual-axis cylinder drives the rotating plate to rotate through the connecting part, so that the rotating plate drives the slider to move through the push plate, and then drives the clamping plate to move, so as to clamp the sheet metal part, and the clamping plate can clamp the sheet metal part to be processed.

[0013] 2. The laser cutting device for sheet metal processing, when the rotating plate rotates inward, can drive the second linkage rod to move downward through the first linkage plate, so that the second linkage rod drives the second arc plate to move downward through the first linkage rod, so that the second arc plate can drive the sliding cylinder to move downward. When the sliding cylinder moves downward, it can make the two clamping plates clamp the sheet metal part at the same time, and the left and right sides can move synchronously through the sliding cylinder.

[0014] 3. When the sheet metal part to be clamped is irregular in shape, the electric telescopic rod is opened so that the electric telescopic rod can move through the moving plate. The first threaded rod is rotated so that the first threaded rod drives the anti-slip plate to move downward so that the bottom of the anti-slip plate can contact the top of the sheet metal part to clamp the sheet metal part, making the sheet metal part more stable during the cutting process.

[0015] 4. This laser cutting device for sheet metal processing, through its movable mechanism, allows for adjustment of the position of the movable frame. The first motor is activated, causing it to drive a worm gear to rotate via a worm. This worm gear, in turn, drives a rotating disk via a rotating rod. The rotating disk, through a second short rod, drives a second linkage plate to rotate. This second linkage plate then moves a movable block, which in turn moves the movable frame, allowing for position adjustment. Finally, the movable frame moves the laser cutter, enabling the laser cutter to cut different positions on the sheet metal part.

[0016] 5. In the laser cutting device for sheet metal processing, when the second linkage plate rotates, the sliding block can slide inside the second linkage plate, so that when the second linkage plate rotates left and right, the third short rod cannot restrict the rotation range of the second linkage plate.

[0017] 6. The laser cutting device for sheet metal processing, through the set adjustment mechanism, when the position of the laser cutter needs to be adjusted, the second motor is turned on, so that the second motor drives the second threaded rod to rotate, so that the second threaded rod drives the threaded block to move, so that the threaded block can drive the laser cutter to move, so that the laser cutter can cut the sheet metal.

The arc block 58 supports and limits the rotating disk 59, making the rotating disk 59 more stable during rotation.

[0030] Example 4

[0031] See Figure 1-9 Furthermore, based on Embodiment 1, the adjustment mechanism 4 further includes a push rod 41, which is rotatably connected to the top of the second linkage plate 56. A moving block 42 is fixedly connected to the front of the push rod 41. A moving frame 45 is fixedly connected to the top of the moving block 42. A support block 43 is fixedly connected to the front of the bottom of the moving frame 45. The support block 43 is slidably connected to the top of the processing table 2. A second motor 46 is fixedly connected to the top of the back end of the moving frame 45. A second threaded rod 48 is fixedly connected to the front of the second motor 46.

A threaded block 47 is threadedly connected to the outer periphery of the second threaded rod 48. A laser cutter 44 is fixedly connected to the bottom of the threaded block 47.

[0032] Furthermore, the top back end of the processing table 2 is provided with a sliding groove corresponding to the size of the moving block 42, and the moving block 42 is slidably connected inside the sliding groove, so that the second linkage plate 56 can drive the moving block 42 to move through the push rod 41 during the rotation, so that the moving block 42 can move inside the sliding groove.

[0033] Furthermore, the movable frame 45 has a limiting groove inside that corresponds to the movement trajectory of the threaded block 47, and the threaded block 47 is slidably connected inside the limiting groove. The limiting groove can limit the threaded block 47, making the threaded block 47 more stable during movement when the second threaded rod 48 drives the threaded block 47 to move.

[0034] Preferably, the connection between the sliding cylinder 3193 and the fixed rod 311 is a sliding connection.

[0035] In actual operation, when this device is used and sheet metal parts need to be clamped, the dual-axis cylinder 313 is opened, causing the dual-axis cylinder 313 to drive the rotating plate 318 to rotate via the connecting piece 314. The rotating plate 318 then drives the slider 322 to move via the push plate 321, which in turn drives the push plate 321 to move. The push plate 321 then drives the clamping plate 328 to move, allowing the clamping plate 328 to clamp the sheet metal parts to be processed. When the rotating plate 318 rotates inward, it drives the second linkage rod 3192 downward via the first linkage plate 315, causing the second linkage rod 3192 to drive the second arc-shaped... The plate 3191 moves downward, allowing the second arc-shaped plate 3191 to drive the sliding cylinder 3193 downward. When the sliding cylinder 3193 moves downward, the two clamping plates 328 can clamp the sheet metal part simultaneously. The sliding cylinder 3193 enables the left and right sides to move synchronously. When the sheet metal part to be clamped is irregular in shape, the electric telescopic rod 327 is opened, allowing the electric telescopic rod 327 to move via the moving plate 323. The first threaded rod 324 is rotated, causing the first threaded rod 324 to drive the anti-slip plate 325 downward, so that the bottom of the anti-slip plate 325 can contact the top of the sheet metal part, clamping the sheet metal part and making the sheet metal part more stable during the cutting process.

[0036] When the position of the movable frame 45 needs to be adjusted, the first motor 54 is turned on, causing the first motor 54 to drive the worm wheel 51 to rotate via the worm gear 52. The worm wheel 51 then drives the rotating disk 59 to rotate via the rotating rod 53. The rotating disk 59 then drives the second linkage plate 56 to rotate via the second short rod 57. When the second linkage plate 56 rotates, the sliding block 502 can slide inside the second linkage plate 56. When the second linkage plate 56 rotates left and right, the sliding block 502 can slide inside the second linkage plate 56. Preferably, when the second linkage plate 56 swings, the sliding block 502 at its bottom can slide along the inner wall of the second linkage plate 56 and rotate around the fixed third short rod 501, thereby adapting to the angle and displacement changes generated when the second linkage plate 56 swings, ensuring smooth movement of the mechanism.

[0037] The second linkage plate 56 can drive the moving block 42 to move, so that the moving block 42 can drive the moving frame 45 to move, so that the position of the moving frame 45 can be adjusted, so that the moving frame 45 can drive the laser cutter 44 to move, so that the laser cutter 44 can cut different positions of the sheet metal parts. When it is necessary to adjust the position of the laser cutter 44, the second motor 46 is turned on, so that the second motor 46 drives the second threaded rod 48 to rotate, so that the second threaded rod 48 drives the threaded block 47 to move, so that the threaded block 47 can drive the laser cutter 44 to move, so that the laser cutter 44 can cut the sheet metal parts.
