[0020] An adjustable support device for precision machining includes a storage slot 1, a workbench 8 is provided at the top of the storage slot 1, a number of screw rods 2 are provided in the storage slot 1, screw rod nuts 21 are threadedly installed on the screw rods 2, and the screw nuts 21 are fixedly connected to the base 3. Two rows of scissor structures are provided in the storage slot 1, and the scissor structures include a first scissor arm 4 and a second scissor arm 5. A telescopic rod 7 is slidably connected to one side of the first scissor arm 4, and the telescopic rod 7 includes an outer rod 71 and an inner sliding rod 72. The outer rod 71 is movably connected to one side of one of the first scissor arms 4, and the inner sliding rod 72 is movably connected to one side of the other first scissor arm 4. A screw hole is opened on one side of the outer rod 71, and a bolt is threadedly connected to the screw hole. The outer rod 71 and the inner sliding rod 72 are fixed by bolts.

[0021] The screw rod 2 is rotatably connected inside the storage groove 1, and the base 3 has a bottom groove. The fixed connection of the screw rod 2 ensures that it will not move or shake during operation, thereby providing a stable support foundation. This stability is crucial for precision machining because it helps to reduce machining errors caused by equipment vibration or movement.

[0022] Both ends of the first scissor arm 4 are fixedly connected to a slider, one end of the second scissor arm 5 is fixedly connected to the slider, the other end of the second scissor arm 5 is hinged to one end of the bottom groove, the first scissor arm 4 and the second scissor arm 5 are hinged, the scissor structure is slidably connected to the bottom groove, the first scissor arm 4 and the second scissor arm 5 are connected by a hinged manner, forming a stable support structure, which can disperse stress when bearing vertical and horizontal loads, thereby improving the overall stability and load-bearing capacity.

[0023] The four corners of the scissor structure are slidably connected with telescopic rods 7, and the hinges of the first scissor arm 4 and the second scissor arm 5 are slidably installed with supporting telescopic rods 9. The structure of the supporting telescopic rod 9 is the same as that of the telescopic rod 7. Cylinders 6 are provided at both ends of the telescopic rod 7. The addition of telescopic rods 7 and supporting telescopic rods 9 provides additional supporting force for the scissor structure, making the entire structure more stable during the lifting process. They can effectively disperse and withstand the stress and torque generated by the scissor arms during the extension and retraction process, reduce structural deformation and vibration, and improve the overall stability of the equipment.

[0024] The cylinder 6 includes at least a cylinder body and a piston rod. The cylinder body is hinged to the outer rod 71 of the telescopic rod 7, and the piston rod is hinged to the outer rod 71 supporting the telescopic rod 9. The extension or shortening of the cylinder 6 itself will pull and push the first scissor arm 4 to move along the bottom groove on the base 3, thereby changing the angle between the first scissor arm 4 and the second scissor arm 5, and then changing the height of the first scissor arm 4 and the second scissor arm 5 supporting the workbench 8.

[0025] Two rows of slide grooves 81 are respectively opened on the back side of the workbench 8. The workbench 8 is slidably connected to the scissor-type structure. The scissor-type structure itself has good stability and load-bearing capacity. After being connected to the workbench 8 through a sliding connection, the overall stability of the workbench 8 can be further enhanced.

[0026] Working principle:

[0027] When the device is in the non-working state, the screw rod 2 in the storage groove 1 remains fixed, the screw nut 21 is located at the lower position of the screw rod 2 and is connected to the base 3. The bottom groove on the base 3 provides a basis for the sliding of the scissor structure. The scissor structure consists of a first scissor arm 4 and a second scissor arm 5, which are connected by a hinge. Both ends of the first scissor arm 4 and one end of the second scissor arm 5 are fixed with sliders to ensure that the scissor structure can slide smoothly. The telescopic rod 7 includes an outer rod 71 and an inner sliding rod 72, which are fixed to the four corners of the scissor structure by bolts to maintain the initial length. The supporting telescopic rod 9 is also at the initial length and is installed at the hinge of the first scissor arm 4 and the second scissor arm 5. When the shape of the workbench is inconsistent with the storage groove, it is achieved by rotating the screw rod 2. Due to the threaded connection between the screw rod 2 and the screw nut 21, rotating the screw rod will cause the screw nut 21 to drive the base 3 to move in the horizontal direction, thereby changing the position of the base 3 and the scissor structure in the storage groove 1. In order to adapt In response to workbenches or workpieces of different sizes, it is necessary to adjust the distance between the two rows of scissor structures. This is achieved through the telescopic rod 7. By loosening the bolts, adjusting the relative position between the outer rod 71 and the inner sliding rod 72, and then retightening the bolts, changing the length of the telescopic rod 7, and thus adjusting the distance between the two rows of scissor structures. When the height of the workbench 8 needs to be adjusted, it is achieved by adjusting the scissor structure. The relative movement between the first scissor arm 4 and the second scissor arm 5 causes the scissor structure to expand or contract. As the scissor structure expands, the angle between the first scissor arm 4 and the second scissor arm 5 increases, pushing the workbench 8 up. At the same time, the telescopic rod 7 and the supporting telescopic rod 9 will automatically adjust their lengths according to the movement of the scissor structure to maintain the stability and load-bearing capacity of the structure. After the workbench 8 reaches the approximate height and position, if fine-tuning is required, sliding adjustment can be performed through the slide groove 81 between the workbench 8 and the storage groove 1 to adapt to workbenches or workpieces of different shapes and sizes.
