Description

Technical Field

[0001] This utility model relates to the field of marking machines, and particularly to laser 3D marking machines. Background Technology

[0002] A laser 3D marking machine is a device that uses a laser beam to perform three-dimensional engraving or marking on the surface of a workpiece. It uses computer control to control the energy, path, and focus of the laser to form three-dimensional patterns, text, QR codes, or complex structures on the surface of various materials such as metal, plastic, ceramics, and wood. Its core technology lies in extending two-dimensional planar marking to three-dimensional space. By scanning layer by layer or dynamically focusing, it can achieve processing of depth, texture, and relief effects. It is widely used in fields such as electronic components, medical devices, automotive parts, and custom jewelry. The precision of laser marking is usually at the micrometer level. If the workpiece undergoes a slight displacement due to vibration, external force, or its own gravity during processing, it will cause pattern misalignment, blurred lines, or deformation of the three-dimensional structure. Therefore, it is necessary to clamp and limit the workpiece.

[0003] However, in existing laser 3D marking technology, some marking machines use simple clamps to fix the workpiece, which makes it difficult to accurately position workpieces of different sizes and shapes. During the marking process, workpiece shaking and displacement are prone to occur, resulting in blurred marking patterns and positional deviations, which seriously affect the marking quality and efficiency.

[0004] Therefore, we propose a laser 3D marking machine. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a laser 3D marking machine, which drives the connecting column and the transmission ring to rotate synchronously through the rotation of the rotating ring, so that the sliding sleeve moves accordingly, thereby driving the connecting rod to swing, realizing the radial movement of the clamping block, which can flexibly and accurately fix workpieces of different sizes and form a uniformly distributed clamping force.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A laser marking machine includes a marking base, a marking platform fixedly connected to the top of the marking base, a positioning component at the top of the marking platform, a support column fixedly connected to the rear end of the marking platform, a marking laser and its electronic components adapted to the positioning component fixedly connected to the upper end of the support column, and a display screen fixedly connected to the right end of the support column. The positioning component includes a housing, a rotating ring rotatably connected inside the housing, several equidistant connecting columns fixedly connected to the top of the rotating ring, a transmission ring fixedly connected to the top of the connecting columns, several sliding sleeves staggered with the connecting columns rotatably connected to the bottom end of the transmission ring and located at the top of the rotating ring, a connecting rod slidably connected inside the sliding sleeve, a rotating shaft fixedly connected to the outer end of the connecting rod, a fixed ring fixedly connected inside the housing below the rotating ring, the fixed ring rotatably connected to the rotating shaft, a connecting piece fixedly connected to the inner end of the connecting rod located inside the transmission ring, the top end of the connecting piece penetrating the top end of the housing and slidably connected to the housing, and a clamping block fixedly connected to the top end of the connecting piece.

[0008] Furthermore, the fixed ring is provided with a vertical rod that is fixedly connected to the bottom of the outer shell. The top of the vertical rod extends out of the top of the outer shell and is fixedly connected to a positioning platform that is adapted to the clamping block.

[0009] Furthermore, the bottom end of the rotating ring is fixedly connected to a connecting ring that is rotatably connected to the fixed ring.

[0010] Furthermore, a worm gear is fixedly connected to the top end of the transmission ring.

[0011] Furthermore, a motor is fixedly connected inside the housing, and a worm gear meshing with a worm wheel is fixedly connected to the transmission end of the motor.

[0012] Furthermore, the top end of the fixed ring is provided with an annular groove that is adapted to the connecting ring, and the annular groove is rotatably connected to the connecting ring.

[0013] Furthermore, the inner end of the clamping block is provided with a groove adapted to the positioning platform.

[0014] Furthermore, the upper end of the clamping block is hollowed out.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1.

[0018] 3. The self-locking characteristics of the worm gear and worm ensure that the clamping block is fixed in position after positioning, ensuring smooth marking operations and achieving stable power transmission.

[0019] 4. The hollowed-out design of the clamping block reduces weight and the load on the rotating ring, making the transmission more flexible and improving the operating efficiency of the equipment. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0028] Reference Figures 1 to 5As shown, in a preferred embodiment of this utility model, a laser 3D marking machine includes a marking base 1. A marking platform 2 is fixedly connected to the top of the marking base 1. A positioning component 6 is provided at the top of the marking platform 2. A support column 3 is fixedly connected to the rear end of the marking platform 2. A marking laser and its electronic components 4, adapted to the positioning component 6, are fixedly connected to the upper end of the support column 3. A display screen 5 is fixedly connected to the right end of the support column 3. The positioning component 6 includes a housing 601. A rotating ring 606 is rotatably connected inside the housing 601. A plurality of equidistant connecting columns 608 are fixedly connected to the top of the rotating ring 606. A transmission ring 607 is fixedly connected to the top of the connecting columns 608. At the bottom of 07 and at the top of the rotating ring 606, there are several sliding sleeves 610 that are staggered with the connecting column 608. The sliding sleeve 610 is slidably connected to the inside of the sliding sleeve 611. The outer end of the connecting rod 611 is fixedly connected to the rotating shaft 605. The inner end of the outer shell 601 is fixedly connected to the fixed ring 604 located below the rotating ring 606. The fixed ring 604 is rotatably connected to the rotating shaft 605. The inner end of the connecting rod 611 is fixedly connected to the connecting piece 612 located inside the transmission ring 607. The top end of the connecting piece 612 passes through the top end of the outer shell 601 and is slidably connected to the outer shell 601. The top end of the connecting piece 612 is fixedly connected to the clamping block 613.

[0029] When the rotating ring 606 rotates, it drives the connecting column 608 and the transmission ring 607 to rotate synchronously. The sliding sleeve 610 moves with the transmission ring 607 and the rotating ring 606, thereby driving the connecting rod 611 to swing around the rotating shaft 605 as the fulcrum. This, in turn, drives the connecting piece 612 and the clamping block 613 to move radially, thereby clamping or releasing the workpiece and forming a uniformly distributed clamping force, which can flexibly and accurately fix workpieces of different sizes.

[0030] The fixed ring 604 has a vertical rod 602 that is fixedly connected to the bottom of the outer shell 601. The top of the vertical rod 602 extends out of the top of the outer shell 601 and is fixedly connected to a positioning platform 603 that is adapted to the clamping block 613.

[0031] The positioning stage 603 provides bottom support for the workpiece, and the clamping block 613 clamps the workpiece to ensure that the workpiece remains stable during the marking process, avoiding deviation in the marking position due to shaking, which can effectively improve the marking accuracy.

[0032] The bottom end of the rotating ring 606 is fixedly connected to a connecting ring 609 that is rotatably connected to the fixed ring 604;

[0033] The connection between the connecting ring 609 and the annular groove at the top of the fixed ring 604 provides stable support and a rotation track for the rotating ring 606, reduces radial sway during rotation, ensures the smoothness and accuracy of the movement of the clamping block 613, and makes the clamping operation more stable and reliable.

[0034] A worm gear 614 is fixedly connected to the top end of the transmission ring 607;

[0035] By utilizing the cooperation of the worm gear 614 and the worm 616, the self-locking characteristics of the worm gear 614 and the worm 616 can be used to ensure that the clamping block 613 remains in a fixed position after positioning, preventing it from loosening due to external force during the marking process, ensuring the smooth progress of the marking operation, and at the same time, power transmission can be carried out.

[0036] A motor 615 is fixedly connected inside the housing 601, and a worm 616 that meshes with a worm gear 614 is fixedly connected to the transmission end of the motor 615.

[0037] The mechanical power transmission is achieved by the meshing transmission of the worm gear 616 and worm wheel 614 driven by the motor 615, which makes the rotation of the transmission ring 607 more stable. At the same time, it is convenient to accurately control the moving speed and position of the clamping block 613, improve the positioning accuracy, and achieve precise positioning of the workpiece.

[0038] The top end of the fixed ring 604 is provided with an annular groove that is adapted to the connecting ring 609, and the annular groove is rotatably connected to the connecting ring 609;

[0039] The annular groove provides guidance and limit for the connecting ring 609, ensuring that the rotating ring 606 can only rotate along a fixed trajectory, further enhancing the stability of the structure, avoiding uneven force on the clamping block 613 due to rotational offset, and ensuring consistent clamping effect.

[0040] The inner end of the clamping block 613 is provided with a groove that adapts to the positioning platform 603;

[0041] The groove and the positioning table 603 work together to increase the clamping stability of the workpiece.

[0042] The upper end of the clamping block 613 is hollowed out;

[0043] The hollow design reduces the weight of the clamping block 613 and the load on the rotating ring 606, making the transmission more flexible.

[0044] Specific implementation process: First, place the workpiece to be marked on the positioning table 603, ensuring full contact between the bottom of the workpiece and the positioning table 603. Then, start the motor 615, which drives the worm gear 616 to rotate. The worm gear 616 meshes with the worm wheel 614, thereby driving the transmission ring 607 to rotate. When the transmission ring 607 rotates, it drives the rotating ring 606 to rotate synchronously through the connecting column 608. The sliding sleeve 610 moves with the transmission ring 607 and the rotating ring 606. Under the action of the rotating shaft 605, the connecting rod 611 rotates... The shaft 605 swings as a fulcrum, driving the connecting piece 612 and the clamping block 613 to move radially toward the workpiece until the clamping block 613 firmly clamps the workpiece. At this time, the self-locking characteristics of the worm gear 614 and the worm 616 are used to keep the clamping block 613 in a fixed position. Then, the marking program and parameters are input through the display screen 5, and the marking laser and its electronic components 4 perform 3D marking on the workpiece according to the set program. After the marking is completed, the motor 615 is started in reverse to release the clamping block 613, and the marked workpiece can be taken out.
