Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a height-adjustable device for a diamond-coated wire rack. Background Art

[0002] The preparation technologies of diamond coatings mainly include microwave plasma chemical vapor deposition, DC plasma jet chemical vapor deposition, hot wire chemical vapor deposition, etc. Compared with the other two technologies, the hot wire method can prepare large-area diamond coatings with relatively the lowest cost. It has good industrial promotion potential and is widely used.

[0003] According to the Chinese patent document with announcement number CN220468131U, a height-adjustable device for a diamond-coated wire rack is disclosed, which relates to the technical field of diamond-coated wire racks. The device includes a base, on which four electrode supports are provided. The top ends of two of the electrode supports are fixedly connected to the same left molybdenum electrode, and the top ends of the other two electrode supports are fixedly connected to the right molybdenum electrode. The base is provided with multiple first sleeves below the corresponding filaments. The multiple first sleeves are each plugged into a guide shaft, and the top ends of the multiple guide shafts are fixedly connected to the same stage. The base is provided with an adjustment unit for adjusting the height of the stage. The utility model forms a height adjustment structure by providing a first sleeve, a guide shaft, a second sleeve, an internally threaded rotating sleeve, a first helical gear, a screw, a mounting frame, a rotating shaft, a second helical gear, and a handle, thereby achieving adjustment of the stage height and preventing damage to the coating quality, and is highly practical.

[0004] Based on the search of the above patents and in combination with the adjustment devices in the prior art, it was found that when the above device is in use, the first sleeve and the guide shaft can be combined with the second sleeve, the threaded rotating sleeve, the first helical gear, the screw, the mounting frame, the rotating shaft, the second helical gear and the handle to form a height adjustment structure to adjust the height of the loading platform. However, in actual use, the height of the loading plate requires the staff to manually turn the handle to adjust the height, and the adjusted height cannot be accurately controlled. There will be errors in the height each time it is adjusted, resulting in inconsistent coating quality and inability to achieve precise adjustment. The screw is exposed to the air for a long time and is prone to rust, causing damage to the thread, making effective adjustment impossible, thereby reducing practicality. Utility Model Content

A fixing frame 7 is fixedly connected to the upper end face of the base plate 1, and the upper end face of the fixing frame 7 is arc-shaped. A hydraulic telescopic column 13 is fixedly connected to the fixing frame 7, which is fixed. The frame 7 can fix the hydraulic telescopic column 13 to ensure that the hydraulic telescopic column 13 is sufficiently stable during use. The movable end of the hydraulic telescopic column 13 is fixedly connected to a connecting block 14. The connecting block 14 is fixedly connected to a first rack 15 on one side adjacent to the hydraulic telescopic column 13. The upper end surface of the first rack 15 is meshed with a first gear 16.
