Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a plate positioning device for laser cutting. Background Technology

[0002] Laser cutting uses a focused laser beam to irradiate a sheet material, causing it to melt and vaporize rapidly. At the same time, a high-speed airflow blows away the molten material, thus cutting the workpiece. Laser cutting has high cutting efficiency and high precision.

[0003] In existing technology, when cutting sheet metal, the worker needs to place the sheet metal under a laser emitter, which then emits a laser to cut the sheet metal. At this time, the sheet metal is prone to shaking on the worktable, which can cause deviations in the cutting process. Utility Model Content

[0004] This utility model proposes a plate positioning device for laser cutting to overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plate positioning device for laser cutting, comprising a worktable, the worktable being placed on the ground by means of support legs to provide overall support, a U-shaped plate being disposed on the top of the worktable, and sliding plates being fixedly connected to both sides of the worktable, wherein the two arms of the U-shaped plate can move along the sliding plates, a laser emitter being slidably connected to the surface of the U-shaped plate, wherein the laser emitter can emit laser to process the plate, a support plate being installed on the upper surface of the worktable, and a fixing device being disposed on the upper surface of the support plate, wherein the fixing device can fix the plate.

[0006] The effect achieved by the above components is as follows: when processing the sheet material, the worker moves the sheet material and places it on the upper surface of the support plate. Then, the fixing device fixes the sheet material, and finally, the laser emitter on the U-shaped plate emits a laser to cut the sheet material.

[0007] Preferably, the fixing device includes a plurality of mounting holes evenly spaced on the upper surface of the support plate, two mounting plates disposed on the upper surface of the support plate, the mounting plates having an L-shaped cross-section, wherein the mounting plates are slidably fitted with the mounting holes, a bolt is threadedly inserted into the top of the mounting plate, one end of the bolt is rotatably connected to a clamping plate, two clamping plates are rotatably connected inside the mounting plate, two mutually symmetrical slots are formed inside the mounting holes, wherein the clamping plates are slidably fitted with the slots, a spring is disposed between the two clamping plates, wherein the two ends of the spring are respectively fixedly connected to the two clamping plates, and two push plates are slidably inserted on both sides of the mounting plate, wherein the push plates can drive the two clamping plates to move.

[0008] The aforementioned components achieve the following effect: When it is necessary to fix the sheet metal, the operator presses down on the two push plates, which squeeze the two clamping plates. The two clamping plates move closer together, causing the springs to deform. Then, the operator moves the mounting plate, which is inserted into the mounting hole near the sheet metal. When the clamping plate moves to the position of the slot, the operator releases the push plates. Under the action of the spring's return force, the clamping plate is inserted into the slot, achieving the effect of fixing the mounting plate. Afterward, the operator rotates the bolt, which moves the clamping plate downward. Finally, the clamping plate squeezes the sheet metal, achieving the effect of fixing the sheet metal. This fixing device achieves the effect of fixing the sheet metal, preventing the sheet metal from shaking during laser cutting and thus avoiding the occurrence of unqualified sheet metal processing.

[0009] Preferably, a plurality of protrusions are fixedly connected to the side of the clamp away from the bolt, and the plurality of protrusions are rubber blocks.

[0010] The effect achieved by the above components is to increase the friction between the clamping plate and the plate by setting protrusions, thereby preventing slippage between the clamping plate and the plate.

[0011] Preferably, the top of the mounting plate has two mutually symmetrical limiting rods that slide through it, wherein one end of the limiting rod is fixedly connected to the clamping plate.

[0012] The effect achieved by the above components is that by setting the limit rod, the movement direction of the clamping plate is restricted, thereby improving the stability of the clamping plate movement.

[0013] Preferably, one end of the push plate is rotatably connected to a rotating component, wherein the rotating component is in contact with the card plate.

[0014] The effect achieved by the above components is that by setting the rotating part to rotate relative to the clamping plate, the friction between the push plate and the clamping plate is reduced, making it easier for the push plate to move with the clamping plate.

[0015] Preferably, the inner wall of the mounting hole is fixedly connected to two mutually symmetrical positioning rods, wherein the mounting plate has positioning holes corresponding to the positioning rods, and the size of the positioning rods is adapted to the size of the positioning holes.

[0016] The effect achieved by the above components is that when the mounting plate moves downward in the mounting hole, the positioning rod is inserted into the positioning hole of the mounting plate, thereby restricting the movement direction of the mounting plate and preventing the mounting plate from shaking.

[0017] Preferably, the support plate is provided with a protective device via a mounting hole. The protective device includes a rotating shaft, the two ends of which are rotatably connected to the inner wall of the mounting hole. A protective plate is fixedly connected to the arc surface of the rotating shaft, wherein the size of the protective plate is adapted to the size of the mounting hole. Two coil springs are respectively sleeved on the two ends of the rotating shaft, wherein the two ends of the coil springs are respectively fixedly connected to the inner wall of the mounting hole and the protective plate.

[0018] The aforementioned components achieve the following effect: When the mounting plate needs to be inserted into the mounting hole of the support plate, the mounting plate rotates along with the protective plate. The rotating shaft on the protective plate rotates, the coil spring deforms, and the mounting hole is exposed, facilitating the insertion of the mounting plate. When the operator pulls out the mounting plate, under the action of the coil spring's return force, the protective plate and the rotating shaft rotate, ultimately blocking the mounting hole with the protective plate, thus achieving the effect of protecting the mounting hole. The protective device effectively protects the mounting hole on the support plate, preventing waste generated during sheet metal processing from falling into the mounting hole and causing it to become blocked, thus preventing the mounting plate from being installed.

[0019] Preferably, a baffle is fixedly connected inside the mounting hole, wherein the protective plate fits against the baffle when it completely covers the mounting hole.

[0020] The effect achieved by the above components is that by setting the baffle, the maximum displacement of the protective plate is limited, thus preventing the protective plate from rotating too much during reset, which would expose the mounting holes.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When it is necessary to fix the sheet material, the worker presses down on two push plates, which squeeze two clamping plates. The two clamping plates move closer together, and the springs deform. Then, the worker moves the mounting plate, which is inserted into the mounting hole near the sheet material. When the clamping plate moves to the position of the slot, the worker releases the push plates. Under the action of the spring's return force, the clamping plate is inserted into the slot, achieving the effect of fixing the mounting plate. Afterward, the worker rotates the bolt, which moves the clamping plate downward. Finally, the clamping plate squeezes the sheet material, achieving the effect of fixing the sheet material. The fixing device achieves the effect of fixing the sheet material, preventing the sheet material from shaking during laser cutting and thus preventing the sheet material from being processed unqualified.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Reference Figure 1-6As shown, this embodiment discloses a plate positioning device for laser cutting, including a worktable 1, which is supported by legs placed on the ground; a U-shaped plate 2, which is set on top of the worktable 1, with sliding plates fixedly connected to both sides of the worktable 1, wherein the two arms of the U-shaped plate 2 can move along the sliding plates; a laser emitter 3, which is slidably connected to the surface of the U-shaped plate 2, wherein the laser emitter 3 can emit laser to process the plate; a support plate 4, which is installed on the upper surface of the worktable 1; and a fixing device 5, which is set on the upper surface of the support plate 4, wherein the fixing device 5 can fix the plate. During plate processing, the operator moves the plate, placing it on the upper surface of the support plate 4, then the fixing device 5 fixes the plate, and finally the laser emitter 3 on the U-shaped plate 2 emits laser to cut the plate.

[0034] Reference Figure 1-6 As shown, the fixing device 5 includes several mounting holes 51, which are evenly distributed on the upper surface of the support plate 4; two mounting plates 52, which are disposed on the upper surface of the support plate 4, and the cross-section of the mounting plates 52 is L-shaped, wherein the mounting plates 52 are slidably adapted to the mounting holes 51; bolts 53, which are threaded into the top of the mounting plates 52, and one end of the bolts 53 is rotatably connected to a clamping plate 54; two clamping plates 55, which are rotatably connected to the inside of the mounting plates 52, and the inside of the mounting holes 51 has two mutually symmetrical slots 56, wherein the clamping plates 55 are slidably adapted to the slots 56; a spring 58, which is disposed between the two clamping plates 55, wherein the two ends of the spring 58 are respectively fixedly connected to the two clamping plates 55; and two push plates 57, which are slidably disposed on both sides of the mounting plate 52, wherein the push plates 57 can drive the two clamping plates 55 to move. When it is necessary to fix the sheet material, the worker presses down on the two push plates 57, which squeeze the two clamping plates 55. The two clamping plates 55 move closer to each other, and the spring 58 deforms. Then, the worker moves the mounting plate 52 and inserts it into the mounting hole 51 near the sheet material. When the clamping plate 55 moves to the position of the slot 56, the worker releases the push plates 57. Under the action of the spring 58's return force, the clamping plate 55 inserts into the slot 56, achieving the effect of fixing the mounting plate 52. Then, the worker rotates the bolt 53, which moves the clamping plate 54 downward. Finally, the clamping plate 54 squeezes the sheet material, achieving the effect of fixing the sheet material. The fixing device 5 achieves the effect of fixing the sheet material, preventing the sheet material from shaking during laser cutting and thus avoiding the occurrence of unqualified sheet material processing.

[0035] Reference Figure 1-6As shown, several protrusions 510, which are rubber blocks, are fixedly connected to the side of the clamping plate 54 away from the bolt 53. The protrusions 510 increase the friction between the clamping plate 54 and the plate, preventing slippage. Two symmetrical limiting rods 511 slide through the top of the mounting plate 52, with one end of each limiting rod fixedly connected to the clamping plate 54. The limiting rods 511 restrict the movement direction of the clamping plate 54, improving its stability. A rotating component 59 is rotatably connected to one end of the push plate 57, which engages with the clamping plate 55. The rotation of the rotating component 59 relative to the clamping plate 55 reduces the friction between the push plate 57 and the clamping plate 55, facilitating movement of the push plate 57 with the clamping plate 55. Two symmetrical positioning rods 513 are fixedly connected to the inner wall of the mounting hole 51. The mounting plate 52 has positioning holes 512 corresponding to the positioning rods 513, and the size of the positioning rods 513 matches the size of the positioning holes 512. When the mounting plate 52 moves downward in the mounting hole 51, the positioning rods 513 are inserted into the positioning holes 512 of the mounting plate 52, thereby restricting the movement direction of the mounting plate 52 and preventing the mounting plate 52 from shaking.

[0036] Reference Figure 1-6 As shown, the support plate 4 is provided with a protective device 6 via the mounting hole 51. The protective device 6 includes a rotating shaft 61, the two ends of which are rotatably connected to the inner wall of the mounting hole 51. A protective plate 62 is fixedly connected to the arc surface of the rotating shaft 61, wherein the size of the protective plate 62 is adapted to the size of the mounting hole 51. Two coil springs 63 are respectively sleeved on the two ends of the rotating shaft 61, wherein the two ends of the coil springs 63 are fixedly connected to the inner wall of the mounting hole 51 and the protective plate 62 respectively. When the mounting plate 52 needs to be inserted into the mounting hole 51 of the support plate 4, the mounting plate 52 rotates along with the protective plate 62. The rotating shaft 61 on the protective plate 62 rotates, and the coil spring 63 deforms, exposing the mounting hole 51, making it easier for the mounting plate 52 to be inserted into the mounting hole 51. When the operator pulls out the mounting plate 52, under the action of the return spring force of the coil spring 63, the protective plate 62 and the rotating shaft 61 rotate, and finally the protective plate 62 blocks the mounting hole 51, achieving the effect of protecting the mounting hole 51. The protective device 6 achieves the effect of protecting the mounting hole 51 on the support plate 4, preventing waste generated during the processing of the board from falling into the interior of the mounting hole 51, thus blocking the mounting hole 51 and making it impossible to install the mounting plate 52.

[0037] Reference Figure 1-6As shown, a baffle 64 is fixedly connected inside the mounting hole 51, and the protective plate 62 fits against the baffle 64 when it completely covers the mounting hole 51. By setting the baffle 64, the maximum displacement of the protective plate 62 is limited, preventing the protective plate 62 from rotating too much when resetting, which would expose the mounting hole 51.

[0038] Working principle: When processing the sheet material, the operator moves the sheet material and places it on the upper surface of the support plate 4. Then, the operator presses down on the two push plates 57. The push plates 57, with the help of the rotating part 59, press down on the two clamping plates 55. The two clamping plates 55 move closer to each other, and the spring 58 deforms. Then, the operator moves the mounting plate 52 and inserts it into the mounting hole 51 near the sheet material. At this time, the positioning rod 513 is inserted into the positioning hole 512 of the mounting plate 52, which achieves the effect of restricting the movement direction of the mounting plate 52. When the clamping plate 55 moves to the position of the slot 56, the operator releases it. Push plate 57, under the action of spring 58's return force, inserts clamp plate 55 into clamp slot 56, achieving the effect of fixing mounting plate 52. Then, the operator rotates bolt 53, bolt 53 moves clamp plate 54 downward with bolt 53, and finally clamp plate 54 presses the plate with the help of protrusion 510, achieving the effect of fixing plate. Finally, laser emitter 3 on U-shaped plate 2 emits laser to cut plate. The fixing device 5 achieves the effect of fixing plate, avoiding plate shaking during laser cutting, thus preventing plate from being unqualified.

[0039] When the mounting plate 52 needs to be inserted into the mounting hole 51 of the support plate 4, the mounting plate 52 rotates along with the protective plate 62. The rotating shaft 61 on the protective plate 62 rotates, and the coil spring 63 deforms, exposing the mounting hole 51, making it easier for the mounting plate 52 to be inserted into the mounting hole 51. When the operator pulls out the mounting plate 52, under the action of the return spring force of the coil spring 63, the protective plate 62 and the rotating shaft 61 rotate, and finally the protective plate 62 blocks the mounting hole 51, achieving the effect of protecting the mounting hole 51. The protective device 6 achieves the effect of protecting the mounting hole 51 on the support plate 4, preventing waste generated during the processing of the board from falling into the interior of the mounting hole 51, thus blocking the mounting hole 51 and making it impossible to install the mounting plate 52.
