DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figures 1 to 6 As shown, an embodiment of the utility model provides a lifting mechanism 10, which includes a fixed frame 100, a transmission device 200 and a lifting module 300; the fixed frame 100 is provided with a guide groove 110; the transmission device 200 includes a screw rod 210 and a screw nut 220, the screw rod 210 is connected to the fixed frame 100 and accommodated in the guide groove 110, and the screw nut 220 is transmission-connected with the screw rod 210; the lifting module 300 includes a lifting frame 310 and a lifting device 320, the lifting frame 310 is slidably matched with the guide groove 110, and the screw nut 220 is rotationally connected with the lifting frame 310; the lifting device 320 is arranged on the lifting frame 310, and the lifting device 320 is transmission-connected with the screw nut 220.

[0039] In the lifting mechanism 10 of the present embodiment, the lifting device 320 is arranged on the lifting frame 310, and the lifting device 320 drives the screw nut 220 to rotate relative to the screw 210 to drive the lifting frame 310 to move up and down. At this time, since the lifting device 320 is arranged on the lifting frame 310, the lifting module 300 does not need to occupy the axial space of the fixed frame 100. This arrangement can make the overall structure of the lifting mechanism 10 compact and the occupied space can be optimized.

[0040] In the lifting mechanism 10 of the present embodiment, the lifting device 320 drives the screw nut 220 to rotate relative to the screw 210 to drive the lifting frame 310 to perform lifting movement, so that the overall structure of the upgrading mechanism can be compact and the occupied space can be optimized.

[0041] Specifically, the lifting device 320 includes a mounting frame 321, a driving assembly and an adjusting knob 323. The mounting frame 321 is connected to the lifting frame 310, the driving assembly is connected to the mounting frame 321, and the driving assembly is transmission-connected to the screw nut 220. The adjusting knob 323 is connected to the output end of the driving assembly and is coaxially arranged with the driving assembly.

[0042] Thus, by adjusting the knob 323 and cooperating with the drive assembly, during the use of the lifting mechanism 10, the output end of the drive assembly can be rotated by manually rotating the adjusting knob 323, thereby the position of the screw nut 220 can be rotated and adjusted, thereby realizing the position calibration of the height of the lifting frame 310, with a simple structure and convenient adjustment. When assembling the lifting mechanism 10 of this embodiment, the drive motor 3221 can be first connected to the mounting frame 321 to form a modular structure, and then the two can be connected to the lifting frame 310 to complete the assembly of the lifting module 300, which is convenient to assemble.

[0043] In one embodiment, the driving assembly includes a driving motor 3221, a driving wheel 3222 and a synchronous belt 3223. The driving motor 3221 is connected to the mounting frame 321, the driving wheel 3222 is connected to the output end of the driving motor 3221, the synchronous belt 3223 is respectively connected to the driving wheel 3222 and the screw nut 220, and the adjusting knob 323 is connected to the driving wheel 3222 and is coaxially arranged with the driving wheel 3222.

[0044] In the present embodiment, starting the driving motor 3221 can drive the driving wheel 3222 to rotate, and the screw nut 220 can be driven to rotate through the transmission connection between the driving wheel 3222 and the synchronous belt 3223. At this time, since the screw nut 220 rotates relative to the screw 210, the lifting frame 310 can be driven to move up and down. The overall structure of the driving component is compact, and the manufacturing cost is low, which is convenient for later maintenance. At the same time, in the present embodiment, the driving motor 3221 can adopt a self-locking motor. When the driving motor 3221 stops running, the self-locking function can be realized to avoid the lifting frame 310 from performing additional movement and causing the height of the lifting frame 310 to be offset, thereby improving the operation accuracy of the lifting mechanism 10.

[0045] Furthermore, the transmission device 200 further includes a limit member 230 , which is connected to the lifting frame 310 , and the limit member 230 abuts against an axial end of the screw nut 220 .

[0046] With this arrangement, the limit member 230 can limit the axial movement of the screw nut 220. When the screw nut 220 rotates relative to the screw 210, the driving force of the screw nut 220 is transmitted from the limit member 230 to the lifting frame 310 to drive the lifting frame 310 to move up and down. At this time, the heights of the screw nut 220, the limit member 230 and the lifting frame 310 remain consistent.

[0047] Specifically, the limiting member 230 includes a bearing frame 231 and a thrust bearing 232. The bearing frame 231 is connected to the lifting frame 310, and the thrust bearing 232 is arranged in the bearing frame 231. There are two groups of limiting members 230, and the thrust bearings 232 of the two groups of limiting members 230 are respectively abutted against the opposite ends of the screw nut 220.

[0048] In this embodiment, a mounting groove is provided on the side of the bearing frame 231 facing the screw nut 220, and a thrust bearing 232 is arranged in the mounting groove, and the end of the thrust bearing 232 abuts against the screw nut 220. At this time, the bearing frame 231 is connected through the thrust bearing 232 so that the screw nut 220 can rotate relative to the bearing frame 231, and the limiting members 230 respectively arranged on the upper and lower sides of the screw nut 220 can limit the axial movement of the screw nut 220 to realize the transmission connection between the screw nut 220, the limiting member 230 and the lifting frame 310.

[0049] Furthermore, the fixing frame 100 further includes a guide portion 120 , which is protruding from the guide groove 110 ; the lifting module 300 further includes a guide assembly 330 , which is rotatably connected to the lifting frame 310 , and the guide assembly 330 is in rolling contact with the guide portion 120 .

[0050] Specifically in the present embodiment, the guide portion 120 may be an optical axis disposed on the inner side of the guide groove 110, and the guide assembly 330 may be rotatably connected to the lifting frame 310. When the lifting module 300 is lifted and moved relative to the fixed frame 100, the guide assembly 330 is in rolling contact with the guide portion 120, thereby guiding the movement of the lifting frame 310 relative to the fixed frame 100, so as to improve the smoothness and accuracy of the movement of the lifting module 300.

[0051] In one embodiment, the number of the guide portions 120 is two, and the two guide portions 120 are respectively arranged on opposite sides of the guide groove 110; the lifting frame 310 is provided with an adjustment groove 311, and the guide assembly 330 includes a fixed guide wheel 331, a movable guide wheel 332 and an eccentric slider 333, the fixed guide wheel 331 is rotatably connected to the lifting frame 310 and is in rolling contact with one of the guide portions 120, the eccentric slider 333 is adjustably connected to the adjustment groove 311, the movable guide wheel 332 is rotatably connected to the eccentric slider 333, and the movable guide wheel 332 is in rolling contact with the other guide portion 120.

[0052] The fixing guide wheel 331 is configured to be in a fixed relative position on the lifting frame 310. At this time, the fixing guide wheel 331 is in rolling contact with the guide portion 120 on one side. When the fixing guide wheel 331 is a groove wheel, the movement of the lifting frame 310 toward the fixed frame 100 can also be limited. By arranging the eccentric slider 333 to be connected with the lifting frame 310, the relative position of the eccentric slider 333 on the lifting frame 310 can be adjusted along the length direction of the adjustment groove 311. Of course, during the installation process, the fixing guide wheel 331 is first matched with the guide portion 120 on one side, and then the matching of the movable guide wheel 332 with the guide portion 120 on the other side is adjusted by adjusting the position of the eccentric slider 333 relative to the lifting frame 310, so that the fixing guide wheel 331 and the movable guide wheel 332 can be closely matched with the two groups of guide portions 120 respectively, thereby reducing the moving gap between the guide assembly 330 and the guide portion 120, thereby effectively improving the moving accuracy of the lifting frame 310. Specifically, the eccentric slider 333 and the lifting frame 310 can be connected by threaded fasteners. In this way, the position of the eccentric slider 333 relative to the lifting frame 310 can be adjusted by rotating the threaded fasteners, which has a simple structure and is easy to adjust.

[0053] Furthermore, the eccentric slider 333 is provided with an adjustment hole 3331, and the lifting frame 310 is also provided with a receiving groove 312 and a connecting hole 313, and the connecting hole 313 is arranged on the side of the lifting frame 310; the eccentric slider 333 can be movably accommodated in the receiving groove 312, and the adjustment hole 3331 is located on the side of the lifting frame 310, and the eccentric slider 333 is passed through the connecting hole 313 by a fastener and connected to the adjustment hole 3331, so as to adjust the position of the eccentric slider 333 along the extension direction of the adjustment groove 311.

[0054] In this embodiment, the connecting hole 313 is located on the side of the lifting frame 310, and the adjusting hole 3331 is also arranged on the side of the eccentric slider 333. With this arrangement, after the guide assembly 330 is connected to the lifting frame 310, the operator can conveniently rotate and adjust the threaded fastener from the connecting hole 313. At the same time, since the threaded fastener can be accommodated in the connecting hole 313, the overall structure of the lifting module 300 can also be made compact.

[0055] In one embodiment, the fixed frame 100 is provided with a movable groove 130, and the lifting module 300 further includes a trigger switch 340, which is connected to the lifting frame 310 and suspended in the movable groove 130; when the lifting frame 310 moves to the end of the path, the trigger portion of the trigger switch 340 is used to abut against the inner wall of the movable groove 130.

[0056] It can be understood that when the lifting frame 310 moves relative to the fixed frame 100, the trigger switch 340 can be suspended in the movable groove 130, until the lifting frame 310 moves to the end of the path on the fixed frame 100, the trigger switch 340 can abut against the inner end surface of the movable groove 130, so that the trigger switch 340 can transmit a trigger signal to the control module to determine that the lifting frame 310 has moved to the right position. Of course, in some embodiments, the number of trigger switches 340 can also be two, and the two trigger switches 340 are symmetrically arranged. When the lifting frame 310 moves to the end of the path along its two moving directions, at least one trigger switch 340 contacts the inner wall of the movable groove 130, thereby improving the sensing accuracy of the lifting module 300.

[0057] Specifically, the control module can be but is not limited to various PLCs (programmable logic controller, full name Programmable Logic Control), STM32 (STM32 microcontroller, a 32-bit microcontroller with ARM Cortex-M core), single-chip microcomputer, FPGA (field programmable gate array, full name Field Programmable Gate Array), ARM (ARM processor, full name Advanced RISC Machi ne), etc., which are set inside the device to directly control the device and obtain the operating status of the device.

[0058] The utility model further provides a laser device, which comprises a laser and the lifting mechanism 10 in any one of the above embodiments, wherein the lifting mechanism 10 is connected to the laser.

[0059] It can be understood that, in the laser device of this embodiment, by setting the lifting mechanism 10 in any one of the above embodiments, the lifting mechanism 10 of this embodiment can drive the lifting frame 310 to move up and down by setting the lifting device 320 on the lifting frame 310, and driving the screw nut 220 to rotate relative to the screw 210 through the lifting device 320. At this time, since the lifting device 320 is set on the lifting frame 310, the lifting module 300 does not need to occupy the axial space of the fixed frame 100. Such a setting can make the overall structure of the laser device compact and the occupied space can be optimized.
