Description
Technical Field
[0001] The utility model belongs to the technical field of drilling bench drills, in particular to an adjustable automatic drilling bench drill. Background Art
[0002] A bench drill is a device used for drilling holes in various materials. Its main function is to accurately produce circular holes. In the field of metal processing, it can drill holes in metal plates, pipes or block metal for subsequent bolt connections, pin installation, or to provide channels for the laying of internal lines and pipes. For wood processing, a bench drill can drill holes of appropriate sizes in wood to facilitate the assembly of furniture or the installation of wooden components. In the processing of plastic products, a bench drill can also be used to drill holes to meet the needs of product assembly and fixation. The bench drill can replace the drill bit according to different needs to drill holes of different diameters. By adjusting parameters such as speed and feed rate, it can adapt to drilling tasks with different materials and different precision requirements. It is a versatile and very practical drilling tool.
[0003] At present, during the application of drilling bench drills, their overall design mostly adopts a method in which the drill head can be adjusted up and down. However, in the specific processing process, there are obvious deficiencies. Generally, the drilling table cannot be adjusted in height. As a result, when people of different heights use it, or when drilling products of different sizes, accurate and flexible adjustment cannot be achieved, which greatly affects the convenience of use and the accuracy of processing. In addition, most of the existing drill bit fixing seats use a motor-driven pulley to drive the drill bit to rotate. During use, this driving method not only takes up a large space, but also wastes a lot of cost. At the same time, the belt is prone to wear and looseness after long-term use, affecting the rotation accuracy and stability of the drill bit. Therefore, in order to improve the practicality, convenience and economy of the drilling bench drill, it is urgently necessary to improve and perfect it. Utility Model Content

In addition, the arc-shaped design also makes the entire bench drill more rounded and smooth in appearance, improves the beauty of the product, and gives people a more comfortable visual experience.
[0025] refer to Figure 1-Figure 3 The drilling mechanism 6 includes a hollow main shaft 61 and a driving assembly 62. The hollow main shaft 61 is fixedly mounted on the bottom output end of the driving motor 7. The outer surface of the hollow main shaft 61 is slidably connected with a sleeve 63. The sleeve 63 is slidably connected to the machine box 4. The bottom of the sleeve 63 is rotatably connected to the drill bit fixing seat 64. The top of the drill bit fixing seat 64 and the hollow main shaft 61 are slidably connected to each other.

This design makes the installation and replacement of the drill bit fixing seat 64 more convenient, and can adapt to drill bit fixing seats 64 of different specifications, thereby improving the versatility of the bench drill. The fixed shaft 621 in the driving assembly 62 rotates to drive the second gear 623 to engage with the second rack 622 on the back of the sleeve 63, thereby achieving precise control of the sleeve 63. The drilling depth can be easily adjusted by operating the handle 624. The operation is simple and convenient, which improves work efficiency.

[0027] Principle of use and advantages: By setting the lifting mechanism 5, the present invention has significant advantages when in use. The user can pull the crank 54 to drive the worm 53 to rotate smoothly inside the slide frame 51. During the rotation of the worm 53, the first gear 57 can be driven to rotate synchronously, and the first gear 57 is rotatably connected to the inside of the slide frame 51 and is in a meshing connection state with the first rack 52. As the first gear 57 continues to rotate, the slide frame 51 can be driven to climb and slide on the lifting shaft 3. By flexibly adjusting the sliding position of the slide frame 51 on the lifting shaft 3, the up and down movement of the receiving plate 55 can be accurately adjusted. By adjusting the receiving plate 55 of the drilling product up and down, the overall adjustment and adaptability of the present invention can be demonstrated. Whether it is users of different heights or drilling processing for products of different specifications, it can be easily coped with, which greatly improves the adaptability of the present invention during the overall production and processing, and provides a reliable solution for various complex processing scenarios.
[0028] By setting up the drilling mechanism 6, the device performs well during use. The operating handle 624 can be adjusted to rotate, and the operating handle 624 drives the fixed shaft 621 to rotate. The rotation of the fixed shaft 621 can cause the second gear 623 to rotate. Since the second gear 623 and the second rack 622 are in a meshing connection state, the drive sleeve 63 can be adjusted to slide up and down inside the machine box 4. During this process, the drill bit fixing seat 64 is rotatably connected to the bottom of the sleeve 63, and the top is connected to the main shaft for sliding up and down. As the sleeve 63 slides up and down, the drill bit fixing seat 64 can be driven to move up and down, which provides strong support for flexible up and down drilling processing. In addition, during the drilling process, since the upper end of the drill bit fixing seat 64 is connected to the hollow The inner side of the main shaft 61 is slidably connected and limited by a rectangular block. During the up and down movement, the drive motor 7 can be started to run, and the drive motor 7 drives the hollow main shaft 61 to rotate. The rotation of the hollow main shaft 61 can drive the drill fixing seat 64 to rotate, and the rotation of the drill fixing seat 64 can drive the drill bit in the drilling fixing seat to rotate and drill. The lifting design adopts the drive motor 7 to directly drive the drill bit to rotate and drill. During the overall use, there is no need to use a pulley or adjust the machine box 4 to move up and down. This structural design is simple and stable, and can effectively avoid the vibration damage of the drive motor 7 due to frequent adjustment of the up and down movement of the drive motor 7. The overall adjustment and adaptation performance is excellent, as well as a long service life and strong adaptability.
