[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "vertical", "horizontal", "side", "inside", "outside", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] like Figure 1-8As shown, a laser engraving device for stainless steel processing provided by an embodiment of the present invention is provided, comprising an engraving machine 1, a workbench 2 is movably provided in the middle of the engraving machine 1, a stabilizing mechanism 3 is provided at the lower end of the engraving machine 1, and the stabilizing mechanism 3 comprises an adjusting component 4 and a control component 5, the adjusting component 4 is used to adjust the engraving machine 1 to always be in a horizontal state, and the control component 5 is used to adjust the position of the workbench 2 and ensure the horizontal state of the workbench 2;

[0033] The adjusting assembly 4 includes a connecting block 40, which is arranged at the lower end of the engraving machine 1. A mounting frame 41 is arranged at the lower end of the connecting block 40. A rack rod 42 is slidably arranged in the mounting frame 41. A gear 43 is rotatably arranged in the mounting frame 41. The gear 43 is meshed with the rack rod 42.

[0034] The control component 5 includes a mounting frame 50, and the workbench 2 is placed in the mounting frame 50. One side of the lower end of the mounting frame 50 is provided with one end of two first support rods 51 in a hinged manner, and the other ends of the two first support rods 51 are rotatably arranged on the mounting unit 52. The middle parts of the two first support rods 51 are connected by a connecting rod 53. Two sliding blocks 54 are slidably arranged on the other side of the lower end of the mounting frame 50, and each sliding block 54 is hinged at the lower end of each sliding block 54. One end of a second support rod 55 is hinged, and the other ends of the two second support rods 55 are rotatably arranged with a sliding rod 56. The sliding rod 56 is slidably arranged on the mounting unit 52, and each second support rod 55 is rotatably arranged on the connecting rod 53.

[0035] In another embodiment provided by the present invention, the adjustment component 4 further includes a worm wheel 44, which is rotatably arranged in the mounting frame 41, and a worm 45 is rotatably arranged in the mounting frame 41, the worm 45 is meshed with the worm wheel 44, and the worm wheel 44 is fixedly connected to the gear 43, and an adjustment motor 46 is further arranged in the mounting frame 41, and the output end of the adjustment motor 46 is provided with the worm 45;

[0036] The specific implementation is as follows: during the operation of the engraving machine 1, vibrations will be generated due to the operation of the equipment, and these vibrations will cause the engraving machine 1 to shift, making it difficult to maintain the balanced horizontal state of the engraving machine 1, making it difficult for the engraving machine 1 to accurately engrave the stainless steel surface. To avoid the above situation, the adjustment motor 46 can automatically start and stop and rotate forward and reverse according to the state of the engraving machine 1, so that when the engraving machine 1 is difficult to maintain a horizontal state, the adjustment motor 46 drives the worm 45 to rotate, so that the worm 45 drives the worm wheel 44 meshing with it to rotate, so that the worm wheel 44 drives the gear 43 fixed to it to rotate synchronously, so that the gear 43 drives the rack rod 42 to rise and fall along the mounting frame 41, so that the rack rod 42 adjusts the engraving machine 1 to always be in a horizontal state.

[0037] The adjustment component 4 further includes a plurality of inclination sensors 47, which are arranged on the side of the frame of the engraving machine 1. The engraving machine 1 is also provided with a controller, which is electrically connected to the inclination sensors 47 and the adjustment motor 46.

[0038] The specific implementation is as follows: the inclination sensor 47 is used to measure the horizontal angle change. The inclination sensor 47 can measure the inclination of the measured plane relative to the horizontal position, the parallelism and verticality of the two components. In this way, the inclination sensor 47 monitors the horizontal state of the engraving machine 1 in real time. When the horizontal state of the engraving machine 1 changes, it sends a signal to the controller, so that the controller controls the adjustment motor 46 at the corresponding position to rotate, so that the adjustment motor 46 drives the rack rod 42 to rise and fall along the mounting frame 41 through the worm 45, the worm wheel 44 and the gear 43, so that the rack rod 42 adjusts the engraving machine 1 to always be in a horizontal state, thereby ensuring the engraving effect of the engraving machine 1.

[0039] In another embodiment provided by the present invention, the adjustment assembly 4 further includes an accordion-type protective cover 48, which is sleeved on the outside of the rack rod 42, and the lower end of the accordion-type protective cover 48 is fixed to the lower side of the rack rod 42 by a fixing nut 49, and the upper end of the accordion-type protective cover 48 is arranged at the lower end of the mounting frame 41;

[0040] The specific implementation is as follows: when the rack rod 42 is lifted and lowered along the mounting frame 41, a part of the gear teeth on the rack rod 42 will be exposed to the air, so that dust and other impurities will adhere to the gear tooth surface of the rack rod 42. When the gear teeth with dust and other impurities are meshed with the gear 43, the wear between the gear 43 and the gear teeth on the rack rod 42 will be accelerated, so that the meshing between the gear 43 and the rack rod 42 will be loose, making it difficult for the engraving machine 1 to be accurately adjusted to always maintain a horizontal state. Therefore, an accordion-type protective cover 48 is provided to protect the rack rod 42 to avoid Prevent dust and other impurities from contacting the gear teeth on the rack rod 42, thereby ensuring that the gear 43 is always closely meshed with the gear teeth on the rack rod 42 and reducing wear, so that the rack rod 42 can accurately adjust the engraving machine 1 to always be in a horizontal state; and the fixing nut 49 can adjust the lower end of the accordion-type protective cover 48 to different positions outside the rack rod 42, so that when the rack rod 42 extends to different lengths along the mounting frame 41, the accordion-type protective cover 48 can always protect the gear teeth of the rack rod 42, thereby preventing dust and other impurities from affecting the adjustment of the horizontal state of the engraving machine 1.

[0041] In another embodiment provided by the present invention, two T-shaped slots are symmetrically arranged on one side of the lower end of the installation frame 50, and a T-shaped portion 540 is arranged on the upper end of the sliding block 54, and a T-shaped portion 540 is slidably arranged in each T-shaped slot;

[0042] The specific implementation is as follows: the T-shaped portion 540 can enable the sliding block 54 to be inserted into the T-shaped slot at the lower end of the mounting frame 50, thereby preventing the sliding block 54 from being separated from the mounting frame 50 during movement, and the cooperation between the T-shaped portion 540 and the T-shaped slot can ensure that the first support rod 51 and the second support rod 55 drive the two ends of the mounting frame 50 to rise and fall synchronously, thereby ensuring that the mounting frame 50 and the workbench 2 are always in a horizontal state.

[0043] In another embodiment provided by the present invention, a plurality of top blocks 500 are slidably arranged in the installation frame 50, and a balance spring 501 is arranged between the top block 500 and the installation frame 50;

[0044] The specific implementation is as follows: when the stainless steel workpiece is placed on the workbench 2, the stainless steel workpiece squeezes the top block 500 through the workbench 2, so that the top block 500 squeezes the balance spring 501 and retracts into the mounting frame 50. When a stainless steel workpiece with an offset center of gravity, that is, one end of the stainless steel workpiece is heavy and the other end is light, is placed on the workbench 2, in order to avoid the stainless steel workpiece shaking during the engraving process and causing engraving failure, the support of the top block 500 to the workbench 2 is adjusted by the balance spring 501, so that the top blocks 500 at different positions on the mounting frame 50 form different height positions with the mounting frame 50 under the action of the adjustment spring, so that the mounting frame 50 can adaptively support different positions of the workbench 2 through the top block 500, so that the workbench 2 can self-adjust to support the stainless steel workpiece.

[0045] In another embodiment provided by the present invention, the mounting unit 52 includes a mounting plate 520, which is arranged at the lower ends of the first support rod 51 and the second support rod 55, and a plurality of lifting rods 521 are slidably arranged below the mounting plate 520, and a buffer spring 522 is arranged between the lifting rod 521 and the mounting plate 520, and a support plate 523 is arranged at the lower end of each lifting rod 521 through a ball joint;

[0046] The specific implementation is as follows: under the construction environment, the bottom of the mounting unit 52 contacts the ground, with the ground as support, so that the mounting unit 52 drives the mounting frame 50 to rise through the first support rod 51 and the second support rod 55, so that the mounting frame 50 adjusts the position of the workbench 2. When the mounting unit 52 contacts the ground, due to the uneven state of the ground, the mounting unit 52 affects the adjustment of the workbench 2 when it contacts the ground. In order to avoid the above situation, multiple support plates 523 are set to contact the ground, and each support plate 523 is connected to each lifting rod 521 through a ball joint, so that the multiple support plates 523 can adapt to the uneven ground. At the same time, the buffer spring 522 arranged between each lifting rod 521 and each mounting plate 520 enables the lifting rod 521 to have sufficient support for the mounting plate 520. In this way, the mounting unit 52 can support and limit the ground of the mounting frame 50 and the workbench 2 in different environments through the support plate 523, thereby ensuring the accuracy of laser engraving.

[0047] In another embodiment provided by the present invention, the control assembly 5 further includes an electric push rod 57, which is disposed at the middle of the upper end of the mounting plate 520, and the protruding end of the electric push rod 57 is connected to the sliding rod 56, and two trapezoidal grooves 5200 are symmetrically disposed on the mounting plate 520 about the electric push rod 57, and two trapezoidal blocks 560 are symmetrically disposed on one side of the sliding rod 56 attached to the mounting plate 520, and a trapezoidal block 560 is respectively disposed in each trapezoidal groove 5200 in a sliding manner;

[0048] The specific implementation is as follows: the electric push rod 57 is electrically connected to the controller. When the engraving machine 1 engraves stainless steel workpieces of different thicknesses, in order to adapt to the stainless steel surfaces of different thicknesses to always be within the focal length range of the laser head of the engraving machine 1, the controller controls the start and stop of the electric push rod 57 according to the thickness of the stainless steel workpiece, so that the extended end of the electric push rod 57 is extended or retracted, so that the extended end of the electric push rod 57 drives the sliding rod 56 to slide on the mounting plate 520, so that the sliding rod 56 drives the lower ends of the two second support rods 55 hinged thereto to move, so that the second support rod 55 and the first support rod 51 are connected. The mounting frame 50 is rotated and driven to adjust the vertical position of the workbench 2, so that the surfaces of stainless steel workpieces of different thicknesses are within the focal length range of the laser head of the engraving machine 1, ensuring normal engraving; and when the sliding rod 56 slides on the mounting plate 520, in order to ensure the sliding accuracy of the sliding rod 56 and avoid the sliding rod 56 from being offset during sliding, two trapezoidal blocks 560 are symmetrically arranged at the lower end of the sliding rod 56, and the trapezoidal blocks 560 slide in the trapezoidal groove 5200 on the mounting plate 520, so that the trapezoidal blocks 560 and the trapezoidal groove 5200 can limit and guide the sliding rod 56, ensuring accurate movement of the sliding rod 56.

[0049] Working principle: Choose a suitable processing position and place the laser engraving device. After the laser engraving device is placed, check it and run it for debugging. After debugging, you can start processing. During the installation, debugging and processing, when the laser engraving device engraves stainless steel workpieces, the operation of the equipment will generate vibrations, and these vibrations will cause the engraving machine 1 to shift, making it difficult to maintain the balanced horizontal state of the engraving machine 1, making it difficult for the engraving machine 1 to accurately engrave the stainless steel surface. To avoid the above situation, the inclination sensor 47 monitors the horizontal state of the engraving machine 1 in real time. When the corner support of the engraving machine 1 is insufficient, that is, the rack rod 42 at a corner of the engraving machine 1 is not aligned with the support. When the total length between the mounting frame 41 is too short, the inclination sensor 47 sends a signal to the controller, so that the controller controls the adjustment motor 46 at the corresponding position to rotate. When the controller drives the adjustment motor 46 to rotate according to the state of the engraving machine 1, the adjustment motor 46 drives the worm 45 to rotate, so that the worm 45 drives the worm wheel 44 meshing with it to rotate, so that the worm wheel 44 drives the gear 43 fixed to it to rotate synchronously, so that the gear 43 drives the rack rod 42 to move to the outside of the mounting frame 41, so that the rack rod 42 and the mounting frame 41 can form sufficient support for the engraving machine 1; at the same time, when the corner support of the engraving machine 1 is excessive, that is, when the total length between the rack rod 42 at a corner of the engraving machine 1 and the mounting frame 41 is too long, The inclination sensor 47 sends a signal to the controller, so that the controller controls the adjustment motor 46 at the corresponding position to rotate in the opposite direction. When the controller drives the adjustment motor 46 to rotate in the opposite direction according to the state of the engraving machine 1, the adjustment motor 46 drives the worm 45 to rotate in the opposite direction, so that the worm 45 drives the worm wheel 44 meshing with it to rotate in the opposite direction, so that the worm wheel 44 drives the gear 43 fixed to it to rotate in the opposite direction synchronously, so that the gear 43 drives the rack rod 42 to move into the mounting frame 41, so as to avoid the rack rod 42 and the mounting frame 41 from over-supporting the engraving machine 1, so that the rack rod 42 adjusts the engraving machine 1 to be always in a horizontal state, thereby ensuring the engraving effect of the engraving machine 1; and when the rack rod 42 is lifted and lowered along the mounting frame 41, the rack rod 42 is A portion of the gear teeth on the bar 42 will be exposed to the air, so that dust and other impurities will adhere to the gear tooth surface of the rack bar 42. When the gear teeth with dust and other impurities are meshed with the gear 43, the wear between the gear 43 and the gear teeth on the rack bar 42 will be accelerated, so that the meshing between the gear 43 and the rack bar 42 will be loose, which makes it difficult for the engraving machine 1 to be accurately adjusted to always maintain a horizontal state. Therefore, an accordion-type protective cover 48 is provided to protect the rack bar 42 to prevent dust and other impurities from contacting the gear teeth on the rack bar 42, thereby ensuring that the gear 43 and the gear teeth on the rack bar 42 are always closely meshed and reduce wear, so that the rack bar 42 can accurately adjust the engraving machine 1 to always be in a horizontal state;The fixing nut 49 can adjust the lower end of the accordion-type protective cover 48 to different positions outside the rack rod 42, so that when the rack rod 42 extends to different lengths along the mounting frame 41, the accordion-type protective cover 48 can always protect the gear teeth of the rack rod 42 to prevent dust and other impurities from affecting the adjustment of the horizontal state of the engraving machine 1;

[0050] In order to improve the applicability of the laser engraving device, that is, to enable the laser engraving device to process and engrave stainless steel workpieces of different thicknesses, the controller controls the start and stop of the electric push rod 57 according to the thickness of the stainless steel workpiece, so that the extended end of the electric push rod 57 is extended or retracted, so as to adjust the vertical position of the workbench 2, so that the surfaces of stainless steel workpieces of different thicknesses are within the focal length range of the laser head of the engraving machine 1, ensuring normal engraving. Specifically, when the workpiece is thick, the controller controls the extended end of the electric push rod 57 to extend, so that the extended end of the electric push rod 57 drives the sliding rod 56 on the mounting plate 520 to move away from the electric push rod. When the workpiece is thin, the controller controls the extended end of the electric push rod 57 to retract, so that the extended end of the electric push rod 57 drives the sliding rod 56 to move on the mounting plate 520 toward the direction close to the electric push rod 57. At this time, the second support rod 55 rotates with the first support rod 51 and drives the mounting frame 50 to move vertically upward. The worktable 2 also moves vertically upward with the mounting frame 50, so that the upper surface of the thick workpiece is within the focal length range of the laser head of the engraving machine 1. The upper surface of the thin workpiece is within the focal length range of the laser head of the engraving machine 1, ensuring that the engraving machine 1 can normally engrave the surface of the stainless steel workpiece; and when the sliding rod 56 slides on the mounting plate 520, in order to ensure the sliding accuracy of the sliding rod 56 and avoid the sliding rod 56 from deviating during sliding, two trapezoidal blocks 560 are symmetrically arranged at the lower end of the sliding rod 56, and the trapezoidal blocks 560 slide in the trapezoidal groove 5200 on the mounting plate 520, so that the trapezoidal blocks 560 and the trapezoidal groove 5200 can limit and guide the sliding rod 56, ensuring that the sliding rod 56 moves accurately; the second support rod 55 moves with the sliding rod 56 When rotating and moving, the upper end of the second support rod 55 drives the sliding block 54 to slide at the lower end of the installation frame 50 to ensure that the second support rod 55 can rotate with the first support rod 51 to avoid jamming, and ensure that the installation frame 50 can change its vertical position as the angle between the first support rod 51 and the second support rod 55 changes. When the sliding block 54 moves along the installation frame 50, the T-shaped portion 540 at the upper end of the sliding frame slides in the T-shaped groove under the installation frame 50, so that the cooperation between the T-shaped portion 540 and the T-shaped groove limits and guides the sliding block 54, so as to ensure that the movement of the sliding block 54 is accurate and reliable.

[0051] When the stainless steel workpiece is placed on the workbench 2, the stainless steel workpiece squeezes the top block 500 through the workbench 2, so that the top block 500 squeezes the balance spring 501 and retracts into the mounting frame 50. When a stainless steel workpiece with an offset center of gravity, that is, one end of the stainless steel workpiece is heavy and the other end is light, is placed on the workbench 2, in order to avoid the stainless steel workpiece shaking during the engraving process and causing engraving failure, the support of the top block 500 to the workbench 2 is adjusted by the balance spring 501, so that the top blocks 500 at different positions on the mounting frame 50 form different height positions with the mounting frame 50 under the action of the adjustment spring, so that the mounting frame 50 can adaptively support different positions of the workbench 2 through the top block 500, so that the workbench 2 can self-adjust to support the stainless steel workpiece. In the construction environment, the bottom of the mounting unit 52 contacts the ground, and the ground is used as a support, so that the mounting unit 5 The first support rod 51 and the second support rod 55 drive the installation frame 50 to rise, so that the installation frame 50 adjusts the position of the workbench 2. When the installation unit 52 contacts the ground, the ground is uneven, so that the installation unit 52 contacts the ground and affects the adjustment of the workbench 2. To avoid the above situation, multiple support plates 523 are provided to contact the ground, and each support plate 523 is connected to each lifting rod 521 through a ball joint, so that the multiple support plates 523 can adapt to the uneven ground. At the same time, the buffer spring 522 provided between each lifting rod 521 and each installation plate 520 enables the lifting rod 521 to have sufficient support for the installation plate 520. In this way, the installation unit 52 can support and limit the installation frame 50 and the workbench 2 on the ground in different environments through the support plate 523, thereby ensuring the accuracy of laser engraving.
