Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Figures 1-5 A lathe end face drilling device includes a lathe 1. An inverted F-shaped frame 3 is provided on one side of the lathe 1. The F-shaped frame 3 is securely connected to the lathe 1 via a clamping mechanism at its bottom. The clamping mechanism includes a turntable 17 located below the F-shaped frame 3. The turntable 17 rotates to adjust the height of the entire clamping mechanism, thus adapting to lathes of different thicknesses. A threaded rod 16 is fixedly connected to the top of the turntable 17. The top end of the threaded rod 16 passes through the F-shaped frame 3 and is rotatably connected to a clamping block 15 via a bearing. The bearing structure ensures that the clamping block 15 can still rotate freely when in a fixed position. The clamping block 15 is made of rubber, and its elastic properties... The F-shaped frame 3 is provided with a threaded groove that mates with the threaded rod 16. The engagement of the threaded rod 16 with the threaded groove converts the rotational force into an up-and-down moving force, which drives the clamping block 15 to move. The bottom of the turntable 17 is rotatably connected to a crank handle 18, which provides the convenience of manual operation. A hand-tightening bolt 19 is threadedly connected to the turntable 17. The hand-tightening bolt 19 is used to lock the rotational position of the turntable 17. The top of the hand-tightening bolt 19 passes through the turntable 17 and is fixedly connected to a top block 20. When locked, the top block 20 directly abuts against the surface of the lathe 1. The top block 20 is made of nylon, and its wear-resistant properties extend its service life.

[0020] A fixed plate 4 is fixedly connected to one side of the top of the F-shaped frame 3. A fixed block 5 is fixedly connected to the top of the fixed plate 4. The other side of the fixed block 5 is fixedly connected to the F-shaped frame 3. The fixed block 5 has a triangular structure, which can effectively distribute the force and is used to assist in the support between the fixed plate 4 and the F-shaped frame 3. A pneumatic component 6 is installed on the top of the fixed plate 4. The pneumatic component 6 provides power output for drilling operations. The telescopic end of the pneumatic component 6 passes through the fixed plate 4 and is fixedly connected to a mounting plate 7. A hole drill 8 is fixedly connected to the bottom of the mounting plate 7. The hole drill 8 completes the end face drilling operation under the drive of the pneumatic component 6. Two insertion slots 14 are opened on the top of the lathe 1. A limiting mechanism connected to the two insertion slots 14 is provided on the top of one side of the F-shaped frame 3. Each insertion slot 14 cooperates with a limiting mechanism to achieve device positioning. The limiting mechanism includes two fixed frames 9 fixedly connected to the F-shaped frame 3. Each of the two fixed frames 9 is connected to a movable plate 10 through a spring 13. The spring 13 enables the movable plate 10 to have an automatic reset function. Each of the two fixed frames 9 is provided with an insertion post 11. The two insertion posts 11 are fixedly sleeved with the two movable plates 10 respectively, so that when the movable plate 10 resets, it can synchronously drive the insertion post 11 to reset, ensuring a stable connection. The top of the two insertion posts 11 passes through the two fixed frames 9 and is fixedly connected to the same pull plate 12. The pull plate 12 realizes the synchronous operation of the two insertion posts 11. The bottom of the two insertion posts 11 passes through the F-shaped frame 3 and is inserted into the two insertion slots 14 respectively.

[0021] When using this utility model, the F-shaped frame 3 is first quickly fixed on the lathe 1 by the clamping mechanism. The crank handle 18 is rotated to adjust the threaded rod 16 so that the clamping block 15 and the top block 20 can quickly clamp the lathe 1. The clamping position can be quickly adjusted by loosening the hand-tightening bolt 19. The insertion post 11 of the limiting mechanism can be quickly inserted into or pulled out of the insertion slot 14 of the lathe 1 by pulling the plate 12 to realize the quick positioning and disassembly of the device. After positioning is completed, the pneumatic component 6 is started and the drill 8 can quickly complete the end face drilling operation.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
