Description

Technical Field

[0001] This utility model relates to the field of equipment leveling technology, specifically a leveling worktable for a car key laser engraving machine. Background Technology

[0002] Laser engraving machines can improve engraving efficiency, make the surface of the engraved area smooth and rounded, quickly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object. According to the different laser sources, they can be divided into CO2 non-metallic laser engraving machines and fiber metal engraving machines.

[0003] In existing technologies, laser engraving of car keys requires ensuring that the key surface is strictly parallel to the laser focal plane. Traditional leveling methods have the following problems: low efficiency of manual leveling: it relies on the operator's experience, takes a long time to adjust, and is difficult to meet the needs of mass production; lack of dynamic error compensation: vibration or thermal deformation during the engraving process may cause platform offset, and the lack of a real-time correction mechanism leads to the inability to adjust the level of the processed surface of the car key. Utility Model Content

[0004] The purpose of this invention is to provide a leveling worktable for a car key laser engraving machine. A translation component drives a movable support block to slide on an inclined surface at the top of the base, facilitating height adjustment at the four corners of the worktable to maintain its levelness. During the translation of the movable support block, a rotation drive component rotates an elliptical disk. The different distances from the center to the edge of the elliptical disk also allow for adjustment at the four corners of the worktable. The combination of these two adjustment structures reduces the time required for leveling using a single adjustment method, thereby improving the precision of car key processing and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leveling worktable for a car key laser engraving machine, comprising: Fixed base and processing table; The processing table is movably mounted above the fixed base. The top of the fixed base has symmetrical inclined surfaces, and movable support blocks are slidably mounted on the outer side of the inclined surfaces. Four sets of translation components are arranged around the bottom of the processing table to move the movable support blocks left and right. Each translation component is also equipped with an elliptical disk, which movably fits against the upper surface of the movable support block. The translation components are also equipped with a rotation drive component to rotate the elliptical disk. The translation components and the rotation drive component work together to independently adjust the height of the four corners of the processing table, thereby ensuring that the processing surface of the car key is perpendicular to the laser optical axis.

[0006] Preferably, the translation component includes a support plate fixed to the bottom of the processing table, a lead screw rotatably connected to one side of the support plate via a bearing, an elliptical disc threaded to the outside of the lead screw, and a first drive motor on the outside of a set of support plates, the output shaft of the first drive motor passing through the support plate and fixedly connected to one end of the lead screw.

[0007] Preferably, the rotary drive assembly includes a fixed cylinder fixed to one end of the elliptical disk, a mounting base rotatably connected to the outer side of the fixed cylinder via a bearing, the upper end face of the mounting base slidingly fitting against the bottom of the processing table, a second drive motor fixed to the outer side of the mounting base, and the output shaft of the second drive motor penetrating into the inner cavity of the mounting base and fixed with a worm gear, the worm gear being rotatably connected to the mounting base via a bearing, and a worm wheel meshing with the worm gear fixed to the outer side of the fixed cylinder.

[0008] Preferably, a support rod is fixed at the center of the top of the fixed base, a fixed ball is fixed at the top of the support rod, a support seat is fixed at the center of the bottom of the processing table, and the fixed ball is rotatably connected to the inner cavity of the support seat.

[0010] Preferably, the movable support block has two sets of through holes with parallel inclined surfaces, and a limit rod is slidably installed in the through holes. The two ends of the limit rod are fixed to the top of the fixed base by a fixing block.

[0011] Preferably, a protective frame is fixed to the bottom of the processing table, and the protective frame covers the outside of the fixed base to prevent processing debris and dust from entering.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a translation component to drive a movable support block to slide on the inclined surface at the top of a fixed base, ensuring the angle adjustment of the processing table in the left and right directions. Then, a rotation drive component drives an elliptical disk to rotate, and the distance between the processing table and the movable support block is adjusted by utilizing the change in distance from the center to the edge of the elliptical disk.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figures 1-6 The leveling worktable of a car key laser engraving machine shown includes: Fixed base 1 and processing table 2; The processing table 2 is movably positioned above the fixed base 1. The top of the fixed base 1 is provided with symmetrical inclined surfaces 3, and movable support blocks 4 are slidably arranged on the outer side of the inclined surfaces 3. Four sets of translation components 5 are arranged around the bottom of the processing table 2 to move the movable support blocks 4 left and right. An elliptical disk 6 is also provided on the translation component 5. The elliptical disk 6 is movably attached to the upper end surface of the movable support block 4. A rotary drive component 7 is also provided on the translation component 5 to rotate the elliptical disk 6. The translation component 5 and the rotary drive component 7 cooperate with each other to independently adjust the height of the four corners of the processing table 2, thereby ensuring that the processing surface of the car key is perpendicular to the laser optical axis. A laser interference sensor is installed inside the laser engraving machine to monitor the levelness of the processing surface of the car key. The translation component 5 drives the movable support block 4 to slide on the inclined surface 3 at the top of the fixed base 1, ensuring the angle adjustment of the processing table 2 in the left and right directions. Then, the rotation drive component 7 drives the elliptical disk 6 to rotate. By utilizing the change in distance from the center to the edge of the elliptical disk 6, the distance between the processing table 2 and the movable support block 4 is adjusted. The two horizontal adjustments work together to reduce the time required for a single adjustment method, thereby avoiding errors generated by the car key in the laser engraving machine and improving processing accuracy.

[0018] Among them, such as Figure 2-3 As shown: The translation component 5 includes a support plate 51 fixed to the bottom of the processing table 2. A lead screw 52 is rotatably connected to one side of the support plate 51 via a bearing. An elliptical disk 6 is threaded to the outside of the lead screw 52. A first drive motor 53 is located on the outside of a set of support plates 51. The output shaft of the first drive motor 53 passes through the support plate 51 and is fixedly connected to one end of the lead screw 52. The first drive motor 53 drives the lead screw 52 to rotate, and then the lead screw 52 drives the elliptical disk 6 to translate left and right on the lead screw 52. Through the cooperation of the four sets of lead screws 52 and elliptical disks 6, the height of the four corners of the processing table 2 can be easily adjusted to ensure that the processing surface of the car key installed on the top of the processing table 2 is perpendicular to the laser optical axis.

[0019] Furthermore, such as Figure 4-5 As shown: The rotary drive assembly 7 includes a fixed cylinder 71 fixed to one end of the elliptical disk 6. A mounting base 72 is rotatably connected to the outer side of the fixed cylinder 71 via a bearing. The upper end face of the mounting base 72 slides against the bottom of the processing table 2. A second drive motor 73 is fixed to the outer side of the mounting base 72, and the output shaft of the second drive motor 73 passes through the inner cavity of the mounting base 72 and is fixed with a worm gear 74. The worm gear 74 is rotatably connected to the mounting base 72 via a bearing. A worm wheel 75 that meshes with the worm gear 74 is fixed to the outer side of the fixed cylinder 71. The second drive motor 73 is installed through the cooperation of the fixed cylinder 71 and the mounting base 72. Subsequently, the second drive motor 73 rotates the elliptical disk 6 through the worm gear 74 and the worm wheel 75. By utilizing the different distances from the center to the edge of the elliptical disk 6, the distance between the processing table 2 and the movable support block 4 can be adjusted, which is used to adjust the levelness of the processing table 2.

[0020] Preferred, such as Figure 3 and Figure 6 As shown: A support rod 8 is fixed at the center of the top of the fixed base 1, and a fixed ball 9 is fixed at the top of the support rod 8. A support seat 10 is fixed at the center of the bottom of the processing table 2, and the fixed ball is rotatably connected to the inner cavity of the support seat 10. Through the cooperation of the fixed ball 9 and the support seat 10, the processing table 2 can be adjusted at multiple angles. At the same time, the support rod 8 limits the height of the processing table 2 to ensure the stability of the position between the processing table 2 and the fixed base 1.

[0021] It is worth noting that, such as Figure 4 As shown: The outer side of the elliptical disk 6 is provided with a sliding groove 11, and the top of the movable support block 4 is fixed with a slider 12. The slider 12 is slidably disposed in the sliding groove 11. By sliding the slider 12 in the sliding groove 11, it is convenient to use the slider 12 to movably connect the elliptical disk 6 and the movable support block 4. Not only can the movement of the elliptical disk 6 drive the movable support block 4 to move horizontally, but it also ensures that the elliptical disk 6 fits against the top of the movable support block 4, thereby improving the adjustment accuracy.

[0022] In a further preferred embodiment, such as Figure 2 As shown: The movable support block 4 has two sets of through holes with parallel inclined surfaces 3, and a limit rod 13 is slidably installed in the through holes. The two ends of the limit rod 13 are fixed to the top of the fixed base 1 by the fixing blocks. The limit rod 13 limits the movable support block 4 to ensure that the movable support block 4 fits on the inclined surface 3, and avoids the movable support block 4 from separating from the fixed base 1, which would increase the error in the horizontal adjustment of the processing table 2.

[0023] In addition, such as Figure 1 As shown: A protective frame 14 is fixed to the bottom of the processing table 2. The protective frame 14 covers the outside of the fixed base 1 to prevent processing debris and dust from entering. The protective frame 14 protects the processing table 2 from the bottom, preventing dust and debris generated during laser engraving from falling between the processing table 2 and the fixed base 1, interfering with the lead screw 52 and worm gear 74, and affecting the smoothness of equipment operation.

[0024] In practical use, the car key is fixed with a clamp, which is then fixed to the top of the processing table 2. A laser interference sensor is used to detect the vertical distance between the processing surface of the car key and the laser head. The controller on the laser engraving machine drives the first drive motor 53 and the second drive motor 73 to rotate. The first drive motor 53 drives the lead screw 52 to rotate, and the lead screw 52 drives the elliptical disk 6 to move left and right. Then, the elliptical disk 6 drives the movable support block 4 to slide on the inclined surface 3 on the top of the fixed base 1 through the slider 12, which is used to adjust the height of the four corners of the processing table 2. At the same time, the second drive motor 73 drives the worm gear 74 to rotate. The worm gear 74 drives the fixed cylinder 71 and the elliptical disk 6 through the worm wheel 75, causing the elliptical disk 6 to rotate and change the distance between the lead screw 52 and the movable support block 4, thereby adjusting the height of the four corners of the processing table 2. The two work together to adjust the level of the processing table 2 in the shortest time, ensuring processing accuracy.

[0025] It is worth noting that, in order to improve accuracy, the lead screw 52 and the movable support block 4, as well as the worm 74 and the worm wheel 75, are manufactured using high-precision machining equipment to avoid the impact of gaps on the debugging accuracy.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
