Description
Technical Field
[0001] This utility model relates to the field of bracket technology, and more specifically, to a manually focused three-dimensional laser cutting bracket. Background Technology
[0002] In industrial manufacturing, precision machining, and personalized customization, 3D laser cutting technology has become a core technology for processing complex curved surfaces and irregularly shaped workpieces due to its advantages such as high cutting accuracy, small heat-affected zone, and strong adaptability. As a key connecting component between the laser cutting head and the workpiece, the 3D laser cutting bracket is mainly divided into two categories based on the focusing adjustment method: autofocus brackets and manual focus brackets. While autofocus brackets can automatically adjust focusing parameters through sensors and control systems, their complex structure and high manufacturing cost, coupled with cumbersome parameter calibration processes and difficult equipment maintenance in scenarios involving small batches and diverse workpieces, make them more suitable for large-scale standardized production. Manual focus brackets, on the other hand, due to their relatively simple structure, low cost, and fast operation response, still have irreplaceable application value in small and medium-sized processing enterprises, research institutions, and personalized customization scenarios.
[0003] However, in practical applications, existing manual focusing 3D laser cutting supports mostly use a single screw knob or slider structure for focus adjustment, lacking effective limiting and guiding mechanisms during the adjustment process. When operators turn the knob or push the slider, uneven force applied by the hand can easily cause the support to shift laterally or vibrate, resulting in deviations in the laser focus position. Utility Model Content
[0004] The main purpose of this invention is to provide a manually focused three-dimensional laser cutting bracket, which can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A manually focused 3D laser cutting bracket includes a fixed body, a support frame is provided on the top of the fixed body, an adjustment device is slidably installed inside the support frame, and a laser cutting head is fixedly connected to the side of the adjustment device; The adjusting device includes a lifting plate. A fixed block is fixedly connected to the upper left side of the lifting plate. A movable screw is rotatably installed inside the fixed block. A movable block is threaded onto the outer surface of the movable screw. Support wheels are rotatably installed on both sides of the lower left side of the lifting plate. Positioning rods are fixedly connected to both sides of the lower left side of the lifting plate. An arc-shaped plate is movably sleeved on the outer surface of the positioning rod. Arc-shaped grooves are opened at both ends of the arc-shaped plate. The arc-shaped grooves at both ends are movably sleeved on the outer surfaces of the two positioning rods, respectively. Side frames are fixedly connected to both ends of the left side of the lifting plate. Limiting wheels are rotatably installed inside the side frames. The support wheels and limiting wheels are movably installed on the upper and lower sides of the arc-shaped plate, respectively. A rotating frame is rotatably connected to the side of the arc-shaped plate. The top of the rotating frame is rotatably installed at the lower end of the movable block. The side of the rotating frame is fixedly connected to the laser cutting head.
[0006] Preferably, the support frame includes a connecting frame, with limit rods fixedly connected to both sides of the connecting frame, a lifting adjustment screw rotatably installed inside the connecting frame, a limit frame fixedly connected to the right side of the connecting frame, and sliding grooves provided on both sides of the limit frame.
[0007] Preferably, a sliding block is fixedly connected to the right side of the lifting plate, the sliding block is slidably installed inside the limiting frame, a scale is fixedly connected to both ends of the side of the limiting frame, the lifting plate is movably sleeved on the outer surface of the limiting rod, and the lifting adjustment screw is threadedly installed inside the lifting plate.
[0008] Preferably, both ends of the limiting frame are rotatably installed with limiting adjustment screws, both the upper and lower ends of the limiting frame are slidably connected with positioning blocks, both sides of the positioning blocks are fixedly connected with sliding frames, the sides of the sliding frames are fixedly connected with pointers, the sliding frames are slidably installed inside the sliding groove, and the pointers are slidably installed on the sides of the scale.
[0009] Preferably, the outer surface of the lower end of the left limit adjusting screw and the outer surface of the upper end of the right limit adjusting screw are both provided with external threads. The sliding brackets at both ends are movably sleeved on the outer surface of the limit adjusting screws. The positioning blocks at the upper and lower ends are slidably installed inside the limit brackets. The sliding block on the right side of the lifting plate is located between the positioning blocks at the upper and lower ends.
[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The upper and lower ends are limited by the positioning blocks. The pointer on the side of the scale indicates the precise positioning of the upper and lower ends of the adjustment device. The operator can adjust the position of the adjustment device by rotating the lifting adjustment screw, which is convenient for the operator to focus. 2. The curved plate is limited by the limiting wheels and support wheels. The top of the rotating frame moves to the side. The rotating frame rotates and moves the curved plate to the side on the outer surface of the positioning rod. This causes the angle of the rotating frame to rotate, thereby adjusting the angle of the laser cutting head and preventing the laser cutting head from shifting, which would cause a deviation in the laser focus position.

Detailed Implementation
[0013] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0014] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides a manually focused three-dimensional laser cutting bracket, including a fixed body 1, a support frame 2 and an adjustment device 3. The support frame 2 is disposed on the top of the fixed body 1, and the adjustment device 3 is slidably installed inside the support frame 2. A laser cutting head 4 is fixedly connected to the side of the adjustment device 3. like Figure 3As shown, the adjusting device 3 includes a lifting plate 31 and an arc-shaped plate 35. A fixing block 32 is fixedly connected to the upper left end of the lifting plate 31. A moving screw 33 is rotatably installed inside the fixing block 32. A moving block 34 is threaded onto the outer surface of the moving screw 33. Support wheels 38 are rotatably installed on both sides of the lower left end of the lifting plate 31. Positioning rods 37 are fixedly connected to both sides of the lower left end of the lifting plate 31. The arc-shaped plate 35 is movably sleeved on the outer surface of the positioning rods 37. Arc-shaped plates 35 are opened at both ends. The two ends of the arc-shaped groove 36 are respectively movably sleeved on the outer surface of the two positioning rods 37. The two ends of the left side of the lifting plate 31 are fixedly connected to the side frame 310. The side frame 310 is rotatably installed with the limiting wheel 311. The support wheel 38 and the limiting wheel 311 are respectively movably installed on the upper and lower sides of the arc plate 35. The side of the arc plate 35 is rotatably connected to the rotating frame 39. The top of the rotating frame 39 is rotatably installed at the lower end of the moving block 34. The side of the rotating frame 39 is fixedly connected to the laser cutting head 4.
[0015] Specifically, the arc plate 35 is limited by the limiting wheel 311 and the support wheel 38. The moving screw 33 is rotated, causing the moving block 34 to move on the outer surface of the moving screw 33, which causes the top of the rotating frame 39 to move to the side. The rotating frame 39 rotates and causes the arc plate 35 to move to the side on the outer surface of the positioning rod 37, thereby causing the angle of the rotating frame 39 to rotate, thereby adjusting the angle of the laser cutting head 4.
[0016] like Figure 4 As shown, the support frame 2 includes a connecting frame 21, with limit rods 22 fixedly connected to both sides of the connecting frame 21. A lifting adjustment screw 23 is rotatably installed inside the connecting frame 21. A limit frame 24 is fixedly connected to the right side of the connecting frame 21, and sliding grooves 25 are provided on both sides of the limit frame 24.
[0017] like Figure 5 As shown, a sliding block is fixedly connected to the right side of the lifting plate 31. The sliding block is slidably installed inside the limit frame 24. A scale 210 is fixedly connected to both ends of the side of the limit frame 24. The lifting plate 31 is movably sleeved on the outer surface of the limit rod 22. The lifting adjustment screw 23 is threadedly installed inside the lifting plate 31.
[0018] The limiting frame 24 has a limiting adjustment screw 29 rotatably installed at both ends inside. The upper and lower ends of the limiting frame 24 are slidably connected to a positioning block 26. The two sides of the positioning block 26 are fixedly connected to a sliding frame 27. The side of the sliding frame 27 is fixedly connected to a pointer 28. The sliding frame 27 is slidably installed inside the sliding groove 25. The pointer 28 is slidably installed on the side of the scale 210.
[0019] Among them, the sliding brackets 27 at both ends are movably sleeved on the outer surface of the limit adjusting screw 29, the positioning blocks 26 at both ends are slidably installed inside the limit bracket 24, and the sliding block on the right side of the lifting plate 31 is located between the positioning blocks 26 at both ends.
[0020] Specifically, the outer surface of the lower end of the left limit adjusting screw 29 and the outer surface of the upper end of the right limit adjusting screw 29 are both provided with external threads. By rotating the left limit adjusting screw 29, the upper sliding frame 27 moves inside the sliding groove 25, thereby causing the positioning block 26 to move at the upper end inside the limit frame 24. By rotating the right limit adjusting screw 29, the lower sliding frame 27 moves inside the sliding groove 25, adjusting the position of the lower positioning block 26. The positioning blocks 26 at both ends are used for limiting, and the pointer 28 indicates the position on the side of the scale 210, thus facilitating the adjustment of the position of the adjusting device 3.
[0021] The working process of this utility model is as follows: In use, the outer surface of the lower end of the left limit adjusting screw 29 and the outer surface of the upper end of the right limit adjusting screw 29 are both provided with external threads. By rotating the left limit adjusting screw 29, the upper sliding frame 27 moves inside the sliding groove 25, thereby causing the positioning block 26 to move at the upper end inside the limit frame 24, limiting the upper end of the adjusting device 3. By rotating the right limit adjusting screw 29, the lower sliding frame 27 moves inside the sliding groove 25, adjusting the position of the lower positioning block 26. The positioning blocks 26 at both ends limit the device. The pointer 28 indicates the position of the upper and lower ends of the adjusting device 3 by pointing to the side of the scale 210. The operator can adjust the position of the adjusting device 3 by rotating the lifting adjusting screw 23, which is convenient for the operator to focus. The arc plate 35 is limited by the limiting wheel 311 and the support wheel 38. The moving screw 33 is rotated, causing the moving block 34 to move on the outer surface of the moving screw 33, which in turn causes the top of the rotating frame 39 to move to the side, and the arc plate 35 to move to the side on the outer surface of the positioning rod 37. This causes the rotating frame 39 to rotate, thereby adjusting the angle of the laser cutting head 4 and preventing the laser cutting head 4 from shifting, which would cause a deviation in the laser focus position.
