Detailed implementation manners

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0025] An embodiment of the present utility model discloses a fixed-angle drilling device for processing diesel engine valve stems.

[0026] The present utility model provides a fixed-angle drilling device for processing diesel engine valve stems as Figures 1-4 shown, which includes a base 1 and a baffle 2. The baffle 2 is fixedly connected to the upper surface of the base 1. Two sliders 3 are slidably provided on the upper surface of the base 1. The tops of the two sliders 3 are simultaneously fixedly connected with a connecting frame 4. The tops of the two sliders 3 are simultaneously fixedly connected with an arc-shaped guide rod 5. A movable block 6 is slidably provided on the rod wall of the arc-shaped guide rod 5. A connecting plate 7 is fixedly connected to the side wall of the movable block 6. The top of the connecting plate 7 is fixedly connected with a cylinder 8. The end of the piston rod of the cylinder 8 extends below the connecting plate 7 and is fixedly connected with a first motor 9. The output shaft of the first motor 9 is fixedly connected with a drill rod 10. A cavity is opened in the inner wall of the base 1, and a second motor 12 is fixedly connected to the side wall of the base 1.

[0027] A lead screw 11 is rotatably connected to the inner wall of the cavity of the base 1. A connecting block 13 is threadedly connected to the rod wall of the lead screw 11. A connecting rod 14 is fixedly connected to the side wall of the connecting block 13. A strip-shaped opening is formed in the upper surface of the base 1. One end of the connecting rod 14 away from the connecting block 13 extends to the outside of the strip-shaped opening and is fixedly connected to the bottom of the slider 3. The output shaft of the second motor 12 is fixedly connected to the end of the lead screw 11.

[0028] A fixing plate 15 is fixedly connected to the upper surface of the base 1. A threaded ring 16 is fixedly connected to the inner wall of the fixing plate 15. A screw rod 17 is threadedly connected to the inner wall of the threaded ring 16. A clamping plate 18 is rotatably connected to the rod wall of the screw rod 17. The bottom of the clamping plate 18 is slidably arranged on the upper surface of the base 1. One end of the screw rod 17 away from the clamping plate 18 extends to the outside of the fixing plate 15 and is fixedly connected to a turning handle 19. The turning handle 19 is arranged as a T-shaped rod.

[0029] During use, the rotation of the output shaft of the second motor 12 can drive the rotation of the lead screw 11. The rotation of the lead screw 11 can drive the movement of the connecting block 13 to drive the movement of the connecting rod 14. The movement of the connecting rod 14 can drive the movement of the slider 3 and the connecting frame 4, facilitating the adjustment of the positions of the movable block 6, the connecting plate 7, the cylinder 8 and the first motor 9, and facilitating the drilling treatment of different positions of the diesel engine valve stem. The first motor 9 drives the drill rod 10 to rotate, and the piston rod of the cylinder 8 pushes the first motor 9 downward, enabling stable drilling treatment. The movable block 6 slides along the rod wall of the arc-shaped guide rod 5. The rod body of the arc-shaped guide rod 5 is arranged as a semi-circular ring, enabling the movable block 6 to perform flexible angle adjustment within 180°, which can improve the adjustment of the angles of the first motor 9 and the drill rod 10 to facilitate the drilling of holes at different angles. By rotating the turning handle 19, the rotation of the screw rod 17 can be driven to push the clamping plate 18 to move, enabling the diesel engine valve stem to be stably clamped at the gap between the clamping plate 18 and the baffle 2, ensuring the subsequent drilling quality.

[0030] To keep the movable block 6 stable on the rod wall of the arc-shaped guide rod 5, as Figures 1-4 shown, a cavity is formed in the inner wall of the movable block 6. A spring 20 is fixedly connected to the inner wall of the cavity of the movable block 6. A plurality of limiting grooves are formed in the side wall of the connecting frame 4. The end of the spring 20 is fixedly connected to a limiting block 21. The limiting block 21 extends to the outside of the cavity and is inserted into the inside of the limiting groove. A pulling rope 22 is fixedly connected to the connection between the limiting block 21 and the spring 20. One end of the pulling rope 22 away from the limiting block 21 extends to the outside of the movable block 6 and is fixedly connected to a pulling ring 23.

[0031] The spring 20 can push the limit block 21 to move and extend into the inside of the limit groove, so that the movable block 6 can be kept stable on the rod wall of the arc-shaped guide rod 5. When the movable block 6 needs to be adjusted subsequently, the pull ring 23 can be pulled to drive the pull rope 22 to move, so that the limit block 21 contracts into the inside of the cavity, facilitating the adjustment of the position of the movable block 6.

[0032] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
