[0001] This utility model relates to the field of drilling machine technology, specifically to a sliding device for the drill row of a woodworking drilling machine. Background Technology

[0002] In the woodworking industry, woodworking drilling machines are one of the most common processing equipment. They are mainly used for drilling holes in materials such as wood. The sliding device of the drill row of the woodworking drilling machine has an important impact on the processing accuracy and efficiency.

[0003] Some existing woodworking drilling machines use a motor-driven threaded rod to rotate and move the drill string vertically. This method leaves the threaded rod exposed, making it highly susceptible to interference from flying sawdust during drilling. The sawdust accumulates on the threaded rod's surface, becoming difficult to clean over time. This affects the fit between the threaded rod and the nut, consequently impacting the vertical movement accuracy of the drill string and reducing drilling quality and consistency. Furthermore, the accumulation of sawdust can accelerate wear on the threaded rod, shortening the equipment's lifespan and increasing maintenance costs and frequency.

[0004] Therefore, a sliding device for the drill row of a woodworking drilling machine is proposed. Summary of the Invention

[0026] As shown in Figures 1 to 6, a sliding device for a woodworking drilling machine includes a mounting frame 1. A partition 11 is provided on the surface of the mounting frame 1, and a drive assembly 2 is fixedly mounted on the mounting frame 1. A slider 3 is threadedly fitted onto the surface of the drive assembly 2. As shown in Figures 1, 2, and 3, specifically, the drive assembly 2 includes a first motor 201 fixedly mounted on the top surface of the mounting frame 1. The output end of the first motor 201 passes through the top surface of the mounting frame 1 and is fixedly connected to a connecting rod 202. A threaded rod 203 is rotatably inserted into the bottom surface of the mounting frame 1 and the partition 11. The top end of the threaded rod 203 and the bottom end of the connecting rod 202 are connected by a coupling. The slider 3 is threadedly fitted onto the surface of the threaded rod 203.

[0027] More specifically, the slider 3 is threaded onto the surface of the threaded rod 203. When the first motor 201 starts and drives the connecting rod 202 to rotate the threaded rod 203, the slider 3 moves along the axial direction of the threaded rod 203 due to the thread action, thereby driving the drill string 6 to move vertically and complete the adjustment of the drilling depth.

[0028] Furthermore, a protective cover 4 is fixedly installed on the surface of the slider 3, and the protective cover 4, the bottom surface of the mounting bracket 1, and the partition 11 are movably connected; as shown in Figures 1, 2, 3, 4, and 5, specifically, internal threaded recesses 31 are provided on both sides of the slider 3, and internal threaded through holes 41 are provided on the surface of the protective cover 4. The protective cover 4 is in contact with the surface of the slider 3, and bolts 5 are internally threaded into the internal threaded through holes 41 and internal threaded recesses 31.

[0029] More specifically, the protective cover 4 is firmly fixed to the two side walls of the slider 3 by the internal threaded concave hole 31 and the internal threaded through hole 41, forming a whole. This not only ensures the stability of the protective cover 4, but also facilitates disassembly and installation, and makes it convenient to maintain the threaded rod 203.

[0030] Drill rows 6 are fixedly mounted on the surfaces of the two sets of sliders 3. As shown in Figure 6, specifically, the drill row 6 includes a housing 601 fixedly mounted on the two sets of sliders 3. A drill chuck 602 is rotatably inserted into the bottom surface of the housing 601, and a gear 603 is fixedly sleeved on the surface of each set of drill chucks 602. The gears 603 are meshed with each other. A second motor 604 is fixedly mounted on the top surface of the housing 601. The output end of the second motor 604 is fixedly connected to the top of the drill chuck 602 located in the center.

[0031] More specifically, when the second motor 604 starts, it drives the middle drill chuck 602 to rotate. Through the meshing transmission between gears 603, the other drill chucks 602 rotate synchronously, realizing simultaneous drilling operation of multiple drill bits, which improves work efficiency and drilling accuracy.

[0032] In some practical applications, the protective covers 4 are fixedly installed on both sides of the slider 3, the two sets of protective covers 4 form a U-shaped structure, and the threaded rod 203 is located inside the two sets of protective covers 4.

[0033] More specifically, the two sets of protective covers 4 form a U-shaped structure, which wraps the threaded rod 203 inside, effectively preventing wood chips from entering the threaded connection and affecting the movement accuracy of the slider 3. This ensures both the protective effect and the normal rotation of the threaded rod 203 and the movement of the slider 3, thus ensuring the stable operation of the device.

[0034] In some practical applications, the protective cover 4 is made of rigid material, and the rear sidewall of the protective cover 4 is slidably fitted to the surface of the mounting bracket 1.

[0035] More specifically, the protective cover 4 and the mounting bracket 1 are kept in close contact, which further enhances the protective effect, prevents wood chips from entering the device from the side, and ensures the normal operation and processing accuracy of the entire drilling rig 6 sliding device.

[0036] In summary: Through the operation of the drive component 2, the surface of the drive component 2 is threaded with a slider 3, and the surface of the slider 3 is fixedly mounted with a protective cover 4. The protective cover 4 is movably connected to the bottom surface of the mounting frame 1 and the partition plate 11. This movable connection allows the slider 3 to move flexibly within the mounting frame 1 for guidance. At the same time, the protective cover 4 plays a crucial protective role, effectively preventing sawdust from entering the threaded connection, ensuring the processing accuracy and service life of the device. The two sets of sliders 3 drive the drill row 6 on their surface to move vertically, thereby completing the drilling operation.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
