Description

Technical Field

[0001] This utility model relates to the field of manual turntable technology, and more particularly to a dual-axis manual turntable. Background Technology

[0002] In fields such as machining, optical measurement, scientific research experiments, and teaching demonstrations, it is often necessary to adjust and precisely position workpieces or instruments at multiple angles. As a basic adjustment device, manual turntables are widely used in various experimental platforms and industrial devices. Among them, a dual-axis manual turntable is a mechanical device that can adjust the angle in two mutually perpendicular directions. It is suitable for scenarios that require precise angle positioning, such as optical experiments, precision measurement, laser processing, and angle adjustment of photographic and video equipment. This turntable can be manually operated to achieve fine angle adjustment of the installed equipment in the horizontal direction (azimuth) and the vertical direction (elevation).

[0003] Traditional single-axis manual turntables can only achieve angle adjustment in one direction, which cannot meet the needs of complex spatial angle adjustment. To solve this problem, some equipment uses electric multi-axis turntables. Although they achieve multi-degree-of-freedom adjustment, they have disadvantages such as complex structure, high cost, and inconvenient operation, and are not suitable for ordinary laboratories or small-batch application scenarios.

[0004] Therefore, a dual-axis manual turntable needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the limitations of traditional single-axis turntables in terms of adjustment, and the shortcomings of electric multi-axis turntables in terms of complex structure, high cost, and unsuitability for general laboratories and small-batch applications, this utility model provides a dual-axis manual turntable.

[0006] The dual-axis manual turntable includes a base, a first frame, a support base, a second frame, a worktable, an adjustment mechanism, a reset mechanism, and a display mechanism. The first frame is fixedly connected to the top left side of the base, and the support base is installed on the top right side of the base. The second frame is rotatably connected to the top of the support base, and the worktable is fixedly connected to the top of the second frame. The front and right sides of the first and second frames are respectively provided with adjustment mechanisms. The reset mechanism is located inside the adjustment mechanism, and the display mechanism is located at the outer end of the adjustment mechanism.

[0007] In a preferred embodiment of this utility model, both the first frame and the second frame are made of aluminum alloy.

[0008] In a preferred embodiment of this utility model, the adjustment mechanism includes a worm, a worm wheel, and a rotating handle. The front and right sides of the first frame and the second frame are rotatably connected to the worm. A worm wheel is fixedly connected to the bottom of the worktable, and a worm wheel is fixedly connected to the top left side of the second frame. The two worm wheels are located inside the first frame and the second frame, respectively, and the worm and the worm wheel mesh. The outer ends of the two worms are fixedly connected to the rotating handles.

[0009] In a preferred embodiment of this utility model, the reset mechanism includes a rotating rod, a torsion spring, a screw, and a locking block. The rotating rod is fixedly connected inside each of the two worm gears. The inner ends of the two rotating rods are respectively fitted with torsion springs. The other ends of the torsion springs are respectively connected to the inner walls of the first frame and the second frame. The middle of the outer ends of the two worm gears are threaded with screws. The locking blocks are threaded on the two screws. The locking blocks are slidably connected to the worm gears and engage with the rotating rods.

[0010] In a preferred embodiment of this utility model, the screw is made of stainless steel.

[0011] In a preferred embodiment of the present invention, the display mechanism includes a scale and a pointer. The outer ends of the two worm gears are provided with scales around the outer circumference, and the outer ends of the two worm gears are each equipped with a pointer.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model drives the worm gear and worm wheel transmission by rotating the handle, so that the adjustment mechanism of the first frame controls the worktable to rotate around the vertical axis (to achieve elevation angle adjustment), and the adjustment mechanism of the second frame controls the worktable to rotate around the horizontal axis (to achieve azimuth angle adjustment). The two sets of adjustment mechanisms do not interfere with each other and can be adjusted separately to meet the multi-angle precise positioning requirements under complex working conditions.

[0013] 2. This utility model allows the locking block to disengage from the rotating rod by manually rotating the screw. Under the action of the torsion spring, the rotating rod drives the worm gear to automatically return to the initial position, eliminating the need for repeated manual adjustments and greatly improving operating efficiency. It is especially suitable for application scenarios that require frequent resetting.

[0014] 3. This utility model has a scale and pointer at the outer end of each adjustment mechanism. Users can keep track of the current adjustment angle in real time through the scale value indicated by the pointer, avoid blind operation, and improve the adjustment accuracy and consistency of repeated operations.

[0015] 4. Both the first and second frames of this utility model are made of aluminum alloy, which has a good strength-to-weight ratio, ensuring that the structure is lightweight and has sufficient rigidity and resistance to deformation, making it suitable for various usage environments. Meanwhile, the screw is made of stainless steel, which has excellent corrosion resistance and can adapt to harsh environments such as humidity and dust, extending its service life.

Detailed Implementation

[0022] Example: Dual-axis manual turntable, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it includes a base 1, a first frame 2, a support base 3, a second frame 4, a worktable 5, an adjustment mechanism 6, a reset mechanism 7, and a display mechanism 8. The first frame 2 is installed on the top left side of the base 1 by screws, and the support base 3 is installed on the top right side of the base 1. The second frame 4 is rotatably connected to the top of the support base 3. Both the first frame 2 and the second frame 4 are made of aluminum alloy. The worktable 5 is installed on the top of the second frame 4 by screws. The front and right sides of the first frame 2 and the second frame 4 are respectively provided with adjustment mechanisms 6. The reset mechanism 7 is provided inside the adjustment mechanism 6, and the display mechanism 8 is provided at the outer end of the adjustment mechanism 6.

[0023] like Figure 2 and Figure 3 As shown, the adjustment mechanism 6 includes a worm gear 61, a worm wheel 62, and a rotary handle 63. The worm gear 61 is rotatably connected to the front and right sides of the first frame 2 and the second frame 4. A worm wheel 62 is welded to the bottom of the workbench 5. A worm wheel 62 is welded to the top left side of the second frame 4. The two worm wheels 62 are located inside the first frame 2 and the second frame 4, respectively, and the worm gear 61 meshes with the worm wheel 62. The outer ends of the two worm gears 61 are respectively welded to the rotary handle 63.

[0024] like Figure 3As shown, the reset mechanism 7 includes a rotating rod 71, a torsion spring 72, a screw 73, and a locking block 74. The rotating rod 71 is welded to the inside of each of the two worm gears 61. The inner ends of the two rotating rods 71 ​​are respectively fitted with torsion springs 72. The other ends of the torsion springs 72 are respectively connected to the inner walls of the first frame 2 and the second frame 4. The middle of the outer ends of the two worm gears 61 are threaded with screws 73. The screws 73 are made of stainless steel. The locking blocks 74 are threaded to the two screws 73. The locking blocks 74 are slidably connected to the worm gears 61 and engage with the rotating rods 71.

[0025] like Figure 5 As shown, the display mechanism 8 includes a dial 81 and a pointer 82. The outer ends of the two worm gears 61 are provided with dials 81 around the outer circumference, and the outer ends of the two worm gears 61 are each equipped with pointers 82.

[0026] When using this device, first, install the equipment to be adjusted on the workbench 5 and ensure a secure connection. To adjust the elevation angle (i.e., the workbench 5 rotates around the vertical axis), manually rotate the handle 63 on the front of the first frame 2, causing the worm gear 61 to rotate. The worm gear 61 drives the meshing worm wheel 62 to rotate. Since one worm wheel 62 is fixed to the bottom left side of the second frame 4, this causes the second frame 4 and the workbench 5 to rotate together around the vertical axis, thus achieving elevation angle adjustment. To adjust the azimuth angle (i.e., the workbench 5 rotates around the horizontal axis),... Manually rotate the handle 63 on the right side of the second frame 4 to rotate the worm gear 61. The worm gear 61 drives the meshing worm wheel 62 to rotate. Since the other worm wheel 62 is fixed to the bottom of the worktable 5, it drives the worktable 5 to rotate around the horizontal axis, thus achieving azimuth angle adjustment. Both the first frame 2 and the second frame 4 are made of aluminum alloy, which is lightweight and high-strength, making the overall structure lightweight and strong. During adjustment, the current angle position can be determined by observing the value indicated by the pointer 82 on the scale 81. Stop the operation after reaching the desired angle. During the adjustment process, as the worm 61 rotates, it drives the rotating rod 71 to rotate as well. The torsion spring 72 is twisted and stores elastic potential energy. The locking block 74 rotates with the rotating rod 71 and forms a locking engagement with it, preventing the worm 61 from rotating in the opposite direction. In this state, even if the torsion spring 72 attempts to push the rotating rod 71 back to its original position, it will be unable to move due to the obstruction of the locking block 74. When the angle adjustment is completed and a reset is required, the screw 73 can be manually rotated to allow the locking block 74 to slide along the screw 73, disengaging from the rotating rod 71 and releasing its limiting function. At this time, the rotating rod 71 will not... Once constrained again, the torsion spring 72 releases its stored energy, pushing the rotating rod 71 to rotate in the opposite direction and causing the worm gear 61 to rotate synchronously in the opposite direction, returning it to its initial position. The pointer 82 points to the "0" mark on the dial 81, completing the reset operation. The screw 73 is made of stainless steel, which has good corrosion resistance and mechanical strength, ensuring long-term stability. If further adjustment is needed, simply repeat the above adjustment steps. If no further adjustment is required, ensure that all components are in their natural state to avoid fatigue damage caused by the torsion spring 72 being in a compressed state for a long time.
