Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 and Figure 2 This drilling device includes a driving motor 1. The output end of the driving motor 1 is connected with a driving synchronous pulley 101. The driving synchronous pulley 101 is connected with a driven synchronous pulley 103 through a synchronous belt 102, and a rotating shaft 2 is fixedly connected to the driven synchronous pulley 103. Thus, through the operation of the driving motor 1, the rotating shaft 2 can rotate under the cooperation of the driving synchronous pulley 101, the synchronous belt 102 and the driven synchronous pulley 103. A tight-fitting hole 201 is further opened at the lower part of the rotating shaft 2. The setting of the tight-fitting hole 201 is to adapt to drills 5 of different specifications and ensure the operability during the operation of the device.

[0026] Refer to Figure 3 A spline shaft 3 is sleeved on the rotating shaft 2, and one end of the spline shaft 3 is connected with a servo motor 4. Specifically, a number of splines 301 are arranged on the spline shaft 3, a transmission gear 401 is arranged on the output end of the servo motor 4, and the transmission gear 401 and the above-mentioned splines 301 drive the rotating shaft 2 to move up and down through meshing.

[0027] Under the coordinated cooperation of the above-mentioned rotation operation and lifting operation of the rotating shaft 2, the drill 5 arranged below the rotating shaft 2 is driven to perform rotary lifting operation.

[0028] In the present utility model, refer to Figure 4 An outer sleeve 6 is further sleeved outside the spline shaft 3. While the outer sleeve 6 protects the spline shaft 3 and the rotating shaft 2, it rotates synchronously with the spline shaft 3. At the same time, a sleeve hole 601 is opened at the lower part of the outer sleeve 6, and the spline shaft 601 and the servo motor 4 are connected through the sleeve hole 601. More specifically, the transmission gear 401 arranged on the servo motor 4 meshes with the splines 301 on the spline shaft 3 through the sleeve hole 601 for meshing and matching operation.

[0029] In the present utility model, refer to Figure 5 A clamping sleeve assembly 7 is further sleeved on the outer sleeve 6. The purpose of setting the clamping sleeve assembly 7 is to stably support the whole device. Specifically, the clamping sleeve assembly 7 includes an upper U-shaped clamping block 701 and a lower U-shaped clamping block support seat 702 integrally connected to the upper U-shaped clamping block 701. Of course, the above-mentioned clamping sleeve assembly 7 is not limited to being integrally formed by the above assembly, and other stable methods can also be adopted to stabilize the device.

[0030] In summary, the drilling device of the present utility model has a simple structure, is easy to operate and control. The integrated drive motor drives the rotation shaft to function, the drill bit drills, and the servo motor drives the transmission gear to engage with the splines on the spline shaft arranged outside the rotation shaft, thereby driving the drill bit to move up and down, realizing the synchronous up and down movement and rotation of the drill bit, being able to adapt to the drilling requirements under different production conditions, and having a high safety factor.
